Shedding of genital herpes simplex virus was frequent soon after first-time infection but declined significantly during the first year, based on data from 82 individuals.

Genital herpes simplex virus (HSV) infections remain common and incurable; consequently, the population with residual infection continues to rise, Christine Johnston, MD, of the University of Washington, Seattle, and colleagues wrote. However, data on the viral shedding trajectory of genital HSV-1 are limited, although HSV-1 accounts for an increasing number of infections.

In a study published in JAMA the researchers recruited 82 women with first-episode genital HSV-1 infections from sexual health and primary care clinics in Seattle, between 2013 and 2018. The participants supplied self-collected oral and genital swabs for daily HSV polymerase chain reaction testing for two 30-day periods at 2 months and 11 months after their initial symptoms. The study population was not pregnant and did not have HIV infection. The median age of the participants was 26 years, 54 were women, and 42 had primary HSV-1 infections. Primary HSV-1 infection was defined as the lack of HSV antibody at baseline or an evolving antibody profile, based on the University of Washington HSV Western Blot.

The primary outcome was the rates of genital and oral HSV shedding and lesions at 2 and 11 months and up to 2 years after an initial HSV-1 infection.

At 2 months, approximately two-thirds (64.6%) of the participants had HSV-1 in the genital tract and 29.3% had virus in the mouth. Genital shedding of HSV-1 was detected in 12.1% of 2,264 total testing days at 2 months, but this rate declined to 7.1% of 1,719 testing days at 11 months (relative risk, 0.52).

The researchers identified oral HSV-1 shedding on 3.9% of 2,247 testing days at 2 months, with a slight increase to 5.1% of 1,714 testing days at 11 months.

Both genital and oral lesions were rare, with reports of 2.6% and 0.4%, respectively, at 2 months and 3.8% and 0.5%, respectively, at 11 months.

The risk of genital shedding was significantly higher in individuals with primary HSV-1, compared with those with nonprimary infections (7.9% vs. 2.9%; RR, 2.75). The overall rate of genital shedding was 17.2% for those with primary HSV-1, of which 15.2% was asymptomatic. Oral shedding was similar for individuals with primary and nonprimary HSV in a multivariate analysis.

In addition, HSV-specific CD4+ and CD8+ T-cell responses were identified in all participants, and these remained stable during the study period. No association appeared between rates of genital and oral shedding and the proportion of cells that expressed two, three, or four cytokines.

The current study is the first known to comprehensively assess genital and oral HSV-1 viral shedding using polymerase chain reaction, the researchers wrote. “Characterizing shedding rates is clinically important because patients with genital herpes are often concerned about transmission to sexual partners, which usually occurs in the absence of lesions.”

The study findings were limited by several factors including the 22% loss of participants to follow-up by the end of the first year, and the use of data from a single location with a primarily White population, the researchers noted. Another limitation was reliance on self-reports and the potential underestimation of recurrences because of the possible use of antiviral medications between swabbing periods.

However, the results indicate the early frequency of HSV-1 shedding and suggest that suppressive therapy might benefit individuals with primary HSV-1 during their first year of infection, the researchers said.
 

Findings may improve HSV management

The current study helps fill a knowledge gap regarding the natural history of genital HSV-1 infections, Richard J. Whitley, MD, and Edward W. Hook III, MD, both of the University of Alabama at Birmingham, wrote in an accompanying editorial. Despite the small study population, the data represent the largest cohort to date of individuals with first-episode infection and up to 2 years’ follow-up.

Although HSV-2 shedding is greater and associated with more symptoms, seroprevalence of HSV-2 in the United States is declining, they noted. Therefore, the findings can inform patient counseling and recommendations for antiviral therapy that may extend to managing HSV-1 in pregnant women as well, although no pregnant women were included in the study.

“For clinicians, these data emphasize the importance of determining the HSV viral type in persons presenting with initial episodes of genital herpes to accurately counsel patients regarding risk of clinical recurrence, the likelihood of asymptomatic shedding of virus and hence transmission, and antiviral prophylaxis,” the editorialists emphasized. For investigators, the results should prompt additional studies of the host defense against HSV and improved serological testing.
 

Study supports need for attention to HSV-1

“Genital herpes is an extremely common sexually transmitted infection, and often only HSV-2 is measured,” Sarah W. Prager, MD, of the University of Washington, Seattle, said in an interview. “This study shows that HSV-1 also accounts for a significant amount of genital disease, and should also be considered when determining prevalence of genital herpes.

“I was not surprised to see that viral shedding decreased significantly over the first year after diagnosis, and similarly not surprised that lesions were rare after the initial infection,” said Dr. Prager, who was not involved in the study. “I was somewhat surprised to see that genital HSV-1 shedding was more common than oral shedding.”

Dr. Prager said that she would advise clinicians against serum HSV testing unless someone has an active genital lesion. “Testing after a lesion will often reveal HSV-1, and patients should be counseled that shedding will decrease over the first year. Subsequent genital lesions are uncommon, but certainly possible, and oral lesions and shedding are both rare.” ]

More research is needed in a more diverse population, Dr. Prager emphasized. Following patients for more than a year and learning more about the use of antiviral medications also would be useful.

The study was supported in part by the National Institutes of Health/National Institute of Allergy and Infectious Diseases through grants to several authors, including lead author Dr. Johnston. Dr. Johnston also disclosed personal fees from AbbVie, grants from Gilead, royalties from UpToDate, and personal fees from GlaxoSmithKline unrelated to the current study.

New COVID-19 cases in children inched up in late October, just 1 week after dipping to their lowest level in more than a year, and some measures of pediatric emergency visits and hospital admissions rose as well.

There was an 8% increase in the number of cases for the week of Oct. 21-27, compared with the previous week, but this week’s total was still below 25,000, and the overall trend since the beginning of September is still one of decline, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.

A similar increase can be seen for hospitalizations with confirmed COVID. The rate for children aged 0-17 years fell from 0.44 admissions per 100,000 population at the end of August to 0.16 per 100,000 on Oct. 23. Hospitalizations have since ticked up to 0.17 per 100,000, according to the Centers for Disease Control and Prevention.

Emergency department visits with diagnosed COVID among children aged 16-17 years, as a percentage of all ED visits, rose from 0.6% on Oct. 21 to 0.8% on Oct. 26. ED visits for 12- to 15-year-olds rose from 0.6% to 0.7% at about the same time, with both increases coming after declines that started in late August. No such increase has occurred yet among children aged 0-11 years, the CDC reported on its COVID Data Tracker.

One small milestone reached in the past week involved the proportion of all COVID cases that have occurred in children. The total number of child cases as of Oct. 27 was almost 14.9 million, which represents 18.3% of cases in all Americans, according to the AAP and CHA. That figure had been sitting at 18.4% since mid-August after reaching as high as 19.0% during the spring.

The CDC puts total COVID-related hospital admissions for children aged 0-17 at 163,588 since Aug. 1, 2020, which is 3.0% of all U.S. admissions. Total pediatric deaths number 1,843, or just about 0.2% of all COVID-related fatalities since the start of the pandemic, the CDC data show.

The latest vaccination figures show that 71.3% of children aged 12-17 years have received at least one dose, as have 38.8% of 5- to 11-year-olds, 8.4% of 2- to 4-year-olds, and 5.5% of those under age 2. Full vaccination by age group looks like this: 60.9% (12-17 years), 31.7% (5-11 years), 3.7% (2-4 years), and 2.1% (<2 years), the CDC reported. Almost 30% of children aged 12-17 have gotten a first booster dose, as have 16% of 5- to 11-year-olds.

A real-world analysis confirms that fecal microbiota transplantation (FMT) is highly effective for recurrent Clostridioides difficile infection (rCDI) – and there is no difference between delivery by capsule (cap-FMT) and colonoscopy (colo-FMT).

“We present one of the largest cohorts involving people who received capsule FMT. The finding that capsule FMT is as safe and effective as colonoscopy FMT has practical implications for anyone suffering with rCDI today,” Byron Vaughn, MD, with the division of gastroenterology, hepatology, and nutrition, University of Minnesota, Minneapolis, said in an interview.

The study was published online in Clinical Gastroenterology and Hepatology.

The Food and Drug Administration allows FMT to be used for patients who have failed standard treatment for rCDI under a policy of enforcement discretion.

The past decade has seen an increase in the use of FMT in clinical practice, owing to an increase in cases of rCDI after failure of standard antibiotic therapy.

Unlike antibiotics, which perpetuate and worsen intestinal dysbiosis, FMT restores the diversity and function of host microbiota, effectively breaking the cycle of rCDI, the authors of the study noted. But it’s been unclear whether the efficacy and safety of FMT vary by route of administration.
 

Effective without procedural risks

To investigate, Dr. Vaughn and colleagues evaluated clinical outcomes and adverse events in 170 patients with rCDI who underwent cap-FMT and 96 peers who underwent colo-FMT.

FMT was performed using one of two standardized formulations of microbiota manufactured by the University of Minnesota microbiota therapeutics program: freeze-dried/encapsulated or frozen-thawed/liquid.

Overall, the cure rates of CDI were 86% at 1 month and 81% at 2 months. There was no statistically significant difference at either time between cap-FMT and colo-FMT.

The 1-month cure rate was 84% with cap-FMT and 91% with colo-FMT; at 2 months, the cure rates were 81% and 83%, respectively.

Cap-FMT has a safety and effectiveness profile similar to that of colo-FMT, without the procedural risks of colonoscopy, the researchers concluded.

They cautioned that, although FMT is highly effective overall, patient selection is a key factor to optimizing FMT success.

Older age and hemodialysis were associated with FMT failure by 2 months on multivariate logistic regression.

“These risk factors can help determine if a patient should receive FMT or an alternative therapy for rCDI. This is not to say FMT should be avoided in older patients or those on dialysis, but clinicians should be aware of these associations in light of other options for rCDI,” Dr. Vaughn said.

Confirming prior studies, antibiotic use after FMT was a major factor in its failure. Patient selection for FMT should include an assessment of the potential need for antibiotics after transplant, the researchers noted.

One serious adverse event (aspiration pneumonia) was related to colonoscopy; otherwise, no new safety signals were identified.

As reported in other studies, changes in bowel function, including diarrhea, constipation, gas, and bloating were common, although it’s tough to disentangle gastrointestinal symptoms related to FMT from those after CDI, the researchers said. Importantly, no transmission of an infectious agent related to FMT was identified.
 

Two good options

The researchers said their findings are “highly generalizable” because the population reflects all FMT use by participating institutions and contains a mix of academic centers and private practices.

Many patients included in the study would not have been eligible for a clinical trial, owing to their having many comorbid conditions, including immune compromise and inflammatory bowel disease, the authors noted.

“FMT is recommended by major gastroenterology and infectious disease society guidelines,” Dr. Vaughn said. “Our group, and others, have consistently found strategies that incorporate FMT as cost-effective strategies for treating rCDI.”

However, lack of access to FMT products often is a barrier to treatment, he said.

“A stool banking model, similar to the nonprofit blood banking model, may be a useful solution to ensure equitable access to FMT to all who need it,” Dr. Vaughn added.

Reached for comment, Majdi Osman, MD, MPH, told this news organization that the study is valuable, “as it nicely shows in a real-world setting that capsules and colonoscopy are good options for patients who need this.”

Dr. Osman is chief medical officer of OpenBiome, a nonprofit organization that operates a public stool bank and is the major FMT source in the United States. The organization has provided over 63,000 FMT treatments to over 1,200 hospitals in the United States.

“FMT has become standard of care for patients who failed antibiotic therapy, and certainly is being used widely as a treatment option for these patients who have often run out of existing options,” Dr. Osman said.

Support for the study was provided by a donation from Achieving Cures Together, a nonprofit organization dedicated to advancing microbiome-based research. Dr. Vaughn receives grant support from Takeda, Roche, Celgene, and Diasorin and has received consulting fees from Prometheus and AbbVie. Dr. Osman reported no relevant financial relationships.

The finding that capsule FMT is as safe and effective as colonoscopy FMT has practical implications for anyone suffering with rCDI today,” Byron Vaughn, MD, with the division of gastroenterology, hepatology, and nutrition, University of Minnesota, Minneapolis, said in an interview.

The study was published online in Clinical Gastroenterology and Hepatology.

The Food and Drug Administration allows FMT to be used for patients who have failed standard treatment for rCDI under a policy of enforcement discretion.

The past decade has seen an increase in the use of FMT in clinical practice, owing to an increase in cases of rCDI after failure of standard antibiotic therapy.

Unlike antibiotics, which perpetuate and worsen intestinal dysbiosis, FMT restores the diversity and function of host microbiota, effectively breaking the cycle of rCDI, the authors of the study noted. But it’s been unclear whether the efficacy and safety of FMT vary by route of administration.
 

Effective without procedural risks

To investigate, Dr. Vaughn and colleagues evaluated clinical outcomes and adverse events in 170 patients with rCDI who underwent cap-FMT and 96 peers who underwent colo-FMT.

FMT was performed using one of two standardized formulations of microbiota manufactured by the University of Minnesota microbiota therapeutics program: freeze-dried/encapsulated or frozen-thawed/liquid.

Overall, the cure rates of CDI were 86% at 1 month and 81% at 2 months. There was no statistically significant difference at either time between cap-FMT and colo-FMT.

The 1-month cure rate was 84% with cap-FMT and 91% with colo-FMT; at 2 months, the cure rates were 81% and 83%, respectively.

Cap-FMT has a safety and effectiveness profile similar to that of colo-FMT, without the procedural risks of colonoscopy, the researchers concluded.

They cautioned that, although FMT is highly effective overall, patient selection is a key factor to optimizing FMT success.

Older age and hemodialysis were associated with FMT failure by 2 months on multivariate logistic regression.

“These risk factors can help determine if a patient should receive FMT or an alternative therapy for rCDI. This is not to say FMT should be avoided in older patients or those on dialysis, but clinicians should be aware of these associations in light of other options for rCDI,” Dr. Vaughn said.

Confirming prior studies, antibiotic use after FMT was a major factor in its failure. Patient selection for FMT should include an assessment of the potential need for antibiotics after transplant, the researchers noted.

One serious adverse event (aspiration pneumonia) was related to colonoscopy; otherwise, no new safety signals were identified.

As reported in other studies, changes in bowel function, including diarrhea, constipation, gas, and bloating were common, although it’s tough to disentangle gastrointestinal symptoms related to FMT from those after CDI, the researchers said. Importantly, no transmission of an infectious agent related to FMT was identified.
 

Two good options

The researchers said their findings are “highly generalizable” because the population reflects all FMT use by participating institutions and contains a mix of academic centers and private practices.

Many patients included in the study would not have been eligible for a clinical trial, owing to their having many comorbid conditions, including immune compromise and inflammatory bowel disease, the authors noted.

“FMT is recommended by major gastroenterology and infectious disease society guidelines,” Dr. Vaughn said. “Our group, and others, have consistently found strategies that incorporate FMT as cost-effective strategies for treating rCDI.”

However, lack of access to FMT products often is a barrier to treatment, he said.

“A stool banking model, similar to the nonprofit blood banking model, may be a useful solution to ensure equitable access to FMT to all who need it,” Dr. Vaughn added.

Reached for comment, Majdi Osman, MD, MPH, told this news organization that the study is valuable, “as it nicely shows in a real-world setting that capsules and colonoscopy are good options for patients who need this.”

Dr. Osman is chief medical officer of OpenBiome, a nonprofit organization that operates a public stool bank and is the major FMT source in the United States. The organization has provided over 63,000 FMT treatments to over 1,200 hospitals in the United States.

“FMT has become standard of care for patients who failed antibiotic therapy, and certainly is being used widely as a treatment option for these patients who have often run out of existing options,” Dr. Osman said.

Support for the study was provided by a donation from Achieving Cures Together, a nonprofit organization dedicated to advancing microbiome-based research. Dr. Vaughn receives grant support from Takeda, Roche, Celgene, and Diasorin and has received consulting fees from Prometheus and AbbVie. Dr. Osman reported no relevant financial relationships.

For those affected, recurrent urinary tract infections (UTIs) are sometimes stressful. However, even an informative discussion about risk factors and the imparting of behavioral recommendations can be very helpful for many women. Antibiotic prophylaxis should only be considered once all nonantibiotic therapy options have been exhausted.

One in seven women suffers at least once a year from cystitis. Around a third of those women develop a further urinary tract infection 6-12 months after the first infection. A urinary tract infection is classified as recurrent if two symptomatic episodes have occurred within the last 6 months or if three episodes have occurred within the last 12 months.

There are many different approaches to reducing the recurrence rate of urinary tract infections, Daniel Klussmann and Florian Wagenlehner, MD, of the department and outpatient clinic for urology at the University of Giessen (Germany) wrote in DMW Klinischer Fortschritt. Aside from general information and advice, nonantibiotic therapy options are particularly important for recurrence reduction, with the aim of preventing the development of resistance and the corresponding adverse effects of antibiotics.
 

Fluids and D-mannose

An individual consultation discussion is the most important nonantibiotic strategy. Studies have shown that this strategy alone can lower the frequency of recurrent UTIs. According to the authors, special education programs on the causes and behavioral measures are especially helpful. Included in these programs is the recommendation to drink a sufficient, but not excessive, amount of fluids: approximately 1.5 liters per day. In one randomized study, this level of consumption halved UTI frequency. However, drinking an excessive amount of fluids should also be avoided, otherwise the antimicrobial peptides present in the urine become overly diluted.

The regular consumption of fruit juice, especially of that from berries, is also beneficial, according to the authors. However, study results on long-term prevention using cranberry products are inconsistent, and they are not recommended in the updated guideline. Like cranberries, D-mannose also inhibits the fimbriae of the Escherichia coli bacteria and therefore the bacteria’s ability to bind to the bladder epithelium. The authors cite a study in which, following the intake of 2 g of D-mannose dissolved in a glass of water every day, the rate of urinary tract infections dropped significantly, compared with consumption of placebo.

Additional recommendations in the S3 guideline include various phytotherapeutic products such as bearberry leaves, nasturtium herb, or horseradish root, although studies on the comparability of phytotherapeutic agents are very difficult to execute, the authors conceded.

It is already known that there is a positive correlation (by a factor of 60) between the recurrence rate of UTIs and the frequency of sexual intercourse. Even with contraceptive methods (such as vaginal suppositories, diaphragms or condoms coated with spermicide, and intrauterine devices), the risk of urinary tract infections increases by a factor of 2-14. Sexual abstinence, even if temporary, can be a remedy. Evidence for the recommendation to urinate immediately after coitus is contradictory in the literature, however. Excessive intimate hygiene clearly damages the local protective environment.
 

Estrogen substitution beneficial

For postmenopausal women, there is also the option of local estriol substitution (0.5 mg/day) as another nonantibiotic method of prophylaxis. This treatment serves as therapy for vaginal atrophy and reduces both vaginal colonization with uropathogens and the vaginal pH level. The authors cite Scandinavian studies that detected no increase in the risk of breast cancer from the local application of estriol.

Furthermore, the current guidelines recommend oral immunostimulation with bacterial cell wall components from uropathogenic strains of E. coli (OM-89, Uro-Vaxom). The authors reported on two meta-studies in which the average recurrence rate was reduced by 39%, compared with placebo. In addition, the treatment time for breakthrough infections decreased significantly, and prevention with OM-89 could even be started during acute therapy. Also recommended is parenteral immunostimulation with inactivated pathogens (StroVac). Acupuncture as cutaneous immunostimulation has also displayed a positive protective effect.

Only when nonantibiotic therapy fails and the patient is under a high amount of psychological strain should antibiotic prophylaxis be initiated, according to the authors. A period of 3-6 months should be the target here. When choosing an antibiotic and before starting therapy, the corresponding pathogen should be confirmed through a urine culture, and resistance testing should be performed. On the other hand, single-use, postcoital antibiotic prevention could be an alternative, particularly for women in whom a correlation between recurrent UTIs and sexual intercourse has been suspected, the authors wrote.

The effectiveness of up to three doses of COVID-19 vaccine was moderate overall and significantly lower among individuals with immunocompromising conditions, compared with the general population during the period of Omicron dominance, according to an analysis of data from more than 34,000 hospitalizations.

Previous studies have suggested lower COVID-19 vaccine effectiveness among immunocompromised individuals, compared with healthy individuals from the general population, but data from the period in which Omicron subvariants have been dominant are limited, wrote Amadea Britton, MD, of the Centers for Disease Control and Prevention’s COVID-19 Emergency Response Team, and colleagues.

The CDC currently recommends an expanded primary vaccine series of three doses of an mRNA vaccine, and the Advisory Committee on Immunization Practices has recommended a fourth dose with the new bivalent booster that contains elements of the Omicron variant, the researchers noted.

In a study published in the CDC’s Morbidity and Mortality Weekly Report, the researchers identified 34,220 adults with immunocompromising conditions who were hospitalized for COVID-19–like illness between Dec. 16, 2021, and Aug. 20, 2022. These conditions included solid malignancy (40.5%), hematologic malignancy (14.6%), rheumatologic or inflammatory disorder (24.4%), other intrinsic immune condition or immunodeficiency (38.5%), or organ or stem cell transplant (8.6%). They used data from the CDC’s VISION Network, a multistate database. The data include spring and summer 2022, when the BA.4 and BA.5 Omicron subvariants dominated other strains, and adults with immunocompromising conditions were eligible for a total of four vaccine doses (two primary doses and two boosters). The median age of the study population was 69 years, and 25.7%, 41.7%, and 7.0% had received two, three, and four doses, respectively, of COVID-19 vaccine.

Overall, vaccine effectiveness (VE) among immunocompromised patients was 34% after two vaccine doses, increasing to 71% during days 7-89 after a third dose, then declining to 41% 90 days or more after that dose.

During the full Omicron period, VE was 36% for 14 or more days after dose two, 69% for 7-89 days after dose three, and 44% for 90 or more days after dose three.

When VE was stratified by sublineage period, VE was higher 7 or more days after dose three during the predominance of BA.1 (67%), compared with VE during the dominant periods of BA.2/BA.2.12.1 (32%) and BA.4/BA.5 (35%).

In the later periods when Omicron BA.2/BA.2.12.1 and BA.4/BA.5 variants dominated, and individuals who had received three doses of vaccine were eligible for a fourth, VE against these variants was 32% 90 or more days after dose three and 43% 7 or more days after dose four.

VE was lowest among individuals with potentially more severe immunocompromising conditions, notably solid organ or stem cell transplants, the researchers wrote in their discussion.

The study findings were limited by several factors including the use of ICD-9 and -10 discharge diagnosis codes for immunocompromising conditions, potential confounding in VE models, lack of data on outpatient treatments such as nirmatelvir/ritonavir (Paxlovid), and lack of COVID-19 genomic sequencing data that may have affected which sublineage was identified, the researchers noted.

However, “this study confirms that even with boosters, immunocompromised adults, because of their weakened immune systems, are still at high risk of moderate to severe COVID,” said coauthor Brian Dixon, PhD, of the Regenstrief Institute and Indiana University Richard M. Fairbanks School of Public Health, Indianapolis, in a press release about the study.

“Given the incomplete protection against hospitalization afforded by monovalent COVID-19 vaccines, persons with immunocompromising conditions might benefit from updated bivalent vaccine booster doses that target recently circulating Omicron sublineages, in line with ACIP [Advisory Committee on Immunization Practices] recommendations,” the researchers concluded in the study.

The study was funded by the CDC. The researchers had no financial conflicts to disclose. The VISION Network is a collaboration between the CDC, the Regenstrief Institute, and seven health care systems across the United States: Columbia University Irving Medical Center (New York), HealthPartners (Wisconsin), Intermountain Healthcare (Utah), Kaiser Permanente Northern California, Kaiser Permanente Northwest (Washington State), the University of Colorado, and Paso Del Norte Health Information Exchange (Texas).

In the later periods when Omicron BA.2/BA.2.12.1 and BA.4/BA.5 variants dominated, and individuals who had received three doses of vaccine were eligible for a fourth, VE against these variants was 32% 90 or more days after dose three and 43% 7 or more days after dose four.

VE was lowest among individuals with potentially more severe immunocompromising conditions, notably solid organ or stem cell transplants, the researchers wrote in their discussion.

The study findings were limited by several factors including the use of ICD-9 and -10 discharge diagnosis codes for immunocompromising conditions, potential confounding in VE models, lack of data on outpatient treatments such as nirmatelvir/ritonavir (Paxlovid), and lack of COVID-19 genomic sequencing data that may have affected which sublineage was identified, the researchers noted.

However, “this study confirms that even with boosters, immunocompromised adults, because of their weakened immune systems, are still at high risk of moderate to severe COVID,” said coauthor Brian Dixon, PhD, of the Regenstrief Institute and Indiana University Richard M. Fairbanks School of Public Health, Indianapolis, in a press release about the study.

“Given the incomplete protection against hospitalization afforded by monovalent COVID-19 vaccines, persons with immunocompromising conditions might benefit from updated bivalent vaccine booster doses that target recently circulating Omicron sublineages, in line with ACIP [Advisory Committee on Immunization Practices] recommendations,” the researchers concluded in the study.

The study was funded by the CDC. The researchers had no financial conflicts to disclose. The VISION Network is a collaboration between the CDC, the Regenstrief Institute, and seven health care systems across the United States: Columbia University Irving Medical Center (New York), HealthPartners (Wisconsin), Intermountain Healthcare (Utah), Kaiser Permanente Northern California, Kaiser Permanente Northwest (Washington State), the University of Colorado, and Paso Del Norte Health Information Exchange (Texas).

The US Preventive Services Task Force (USPSTF) published updated recommendations on screening for syphilis on September 27.¹ The Task Force continues to recommend screening for all adolescents and adults who are at increased risk for infection. (As part of previous recommendations, the USPSTF also advocates screening all pregnant women for syphilis early in their pregnancy to prevent congenital syphilis.²)

Who is at increased risk? Men who have sex with men (MSM), those with HIV or other sexually transmitted infections (STIs), those who use illicit drugs, and those with a history of incarceration, sex work, or military service are considered to be at increased risk for syphilis. Additionally, since state and local health departments collect and publish STI incidence data, it’s important to stay up to date on how common syphilis is in one’s community and tailor screening practices accordingly.

Men account for more than 80% of all primary and secondary syphilis infections, and MSM account for 53% of cases in men.³ The highest rates of syphilis are in men ages 25-29 years and 30-34 years (58.1 and 55.7 cases per 100,000, respectively).³

Why screening is important. Primary and secondary syphilis rates have increased steadily from an all-time low of 2.1 per 100,000 in 2000 to 12.7 per 100,000 in 2020.⁴ There were 171,074 cases reported in 2021.⁵

If not detected and treated, syphilis will progress from the primary and secondary stages to a latent form. About one-third of those with latent syphilis will develop tertiary syphilis, which can affect every organ system and cause multiple neurologic disorders.

How to screen. Syphilis screening typically involves a 2-step process. The first test that should be performed is a Venereal Disease Research Laboratory (VDRL) or rapid plasma reagin (RPR) test. This is followed by a treponemal antibody test if the initial test is positive. While the VDRL and RPR tests have high sensitivity, many other conditions can cause a false-positive result, necessitating confirmation with the more specific antibody test.

As far as frequency, the Task Force suggests screening annually for those at continued risk and more frequently (every 3 or 6 months) for those at highest risk.

Treatment for primary, secondary, and early latent syphilis (< 1 year’s duration) is a single intramuscular (IM) injection of benzathine penicillin, 2.4 million units. For late latent syphilis or syphilis of unknown duration, treatment is benzathine penicillin, 2.4 million units, administered in 3 weekly IM doses.

Treatment for those with penicillin allergies depends on the stage of syphilis and whether or not the patient is pregnant. Refer to the STD treatment guidelines for guidance.⁶

The CDC recommends presumptive treatment for anyone who has had sexual contact in the past 90 days with a person who’s been given a diagnosis of primary, secondary, or early latent syphilis.⁶

And finally, remember that all STIs are reportable to your local health department, which can assist with contract tracing and treatment follow-up.

CHARLOTTE, N.C. – RBX2660 could be a new option for people who experience recurrent, debilitating Clostridioides difficile infections.

Following a standard course of antibiotics, a one-time treatment with RBX2660 was successful for three quarters of participants at 8 weeks, according to a new study. It also prevented additional bouts, with 84% of these initial responders remaining free of C. difficile infection at 6 months.

The ongoing phase 3, open-label PUNCH CD3-OLS study expands on clinical trial experience by treating more “real-world” patients. People who might have been excluded from previous research because of comorbidities, such as irritable bowel syndrome, inflammatory bowel disease, and immunosuppression, were included.

The study also placed no limit on the number of previous rounds of C. difficile infections.

“Even when you expand the patient population to make it more generalizable, we’re still seeing both a high cure rate and a high success rate,” Sahil Khanna, MBBS, a gastroenterologist and hepatologist at the Mayo Clinic in Rochester, Minn., said in an interview.

“We also are not seeing any kind of safety signals that can be attributed to this particular product,” he said.

Dr. Khanna presented the findings during the annual meeting of the American College of Gastroenterology, which were also published simultaneously in the journal Drugs. The research by Dr. Khanna and associates received an ACG Outstanding Research Award in the colon category.
 

Study design and results

RBX2660 (Rebyota) is a microbiota-based live biotherapeutic in development from Ferring Pharmaceuticals. The treatment contains human stool collected from prescreened, qualified donors and is prepared according to good manufacturing standards.

After standard-of-care antibiotics and a 72-hour washout period, participants received a single 150-mL dose rectally by enema. RBX2660 is administered by a health care professional.

The median age of study participants was 63 years, with 45% aged 65 years or older, and 70% were women. Overall, 37% of participants had Crohn’s disease and 4% had ulcerative colitis.

At the time of screening, about half of participants had a history of one or two infections with C. difficile, and the remaining half reported three or more episodes.

Of the 402 participants whose outcomes could be analyzed, 75% reported treatment success, meaning no further C. difficile infections at 8 weeks. This was consistent with the 75% of 60 participants free of C. difficile in the interim analysis reported in 2021. Efficacy results were based on a modified intent-to-treat analysis.

Of the 300 participants who responded to RBX2660 at 8 weeks, 262 were followed up to 6 months, with 84% of these reporting no C. difficile recurrence.

“If you succeeded to 8 weeks, there was a high likelihood that you would succeed up to 6 months,” Dr. Khanna said.

For the subset of participants with inflammatory bowel disease, Dr. Khanna noted that the success rates were in the 80% range, which is higher than what is seen in clinic fecal microbiota transplantation programs.
 

Adverse events

Of the participants, 63% reported treatment-emergent adverse events. Most events were mild to moderate in severity, the researchers reported, with diarrhea and abdominal pain being the most common.

“When you look at the treatment-emergent adverse events, it’s important to put them into context in terms of this patient population,” Dr. Khanna said. “This recurrent population has developed underlying gastrointestinal symptoms like abdominal pain, diarrhea, nausea, vomiting, and weight loss.”

Some of these adverse events persist beyond resolution of the C. difficile infection, and the adverse-event profile with RBX2660 is consistent with what is seen following fecal microbiota transplantation, he added.

The serious adverse events “were very, very few,” Dr. Khanna said.

Overall, 11% of participants reported a serious adverse event. The majority were related to the C. difficile infection or an underlying comorbidity, he noted.
 

“Excruciating for patients to deal with”

Traditionally, there could be “some hesitation on the patient’s part [to undergo therapy] just because it’s delivered rectally,” session comoderator Lisa Malter, MD, said in an interview.

However, C. difficile can be “excruciating for patients to deal with,” said Dr. Malter, a gastroenterologist and professor of medicine at New York University Langone Health. They “may be more than willing to take [this agent] because it gets them feeling better.”

“This is a positive adjunct to our current therapies for C. diff in terms of trying to knock it out once a standard course of antibiotics has been administered,” she added.

Currently, people with recurrent C. difficile seek fecal microbiota material from a biobank or from a close friend or loved one.

But Dr. Malter noted that asking someone you know to donate fecal matter for transplantation requires several steps. Donors are screened to make sure they are free of gastrointestinal illness, are not taking any contraindicated medications, and do not have active infection.

Fecal microbiota samples from a biobank are more standardized, but there have been intermittent shutdowns and availability has been limited during the pandemic, she said.

Dr. Malter added that one unanswered question is how much of the colon is covered by therapy delivery via enema compared with colonoscope delivery during fecal microbiota transplantation.

“If it’s delivered colonoscopically, you get the entire colon. In contrast with an enema, you really only hit the left side of the colon,” she said.
 

FDA advisory committee nod

On Sept. 26, the Food and Drug Administration’s Vaccines and Related Biological Products Advisory Committee reviewed evidence for RBX2660. The committee voted 13 to 4 that data were adequate to support the effectiveness of RBX2660 to reduce the recurrence of C. difficile infection in adults following antibiotic treatment for recurrent infections.

Members also voted 12 to 4, with one abstention, that the data were adequate to support the product’s safety.

The FDA often follows its advisory committee recommendations but is not required to do so.

“The hope would be that this would get through the usual FDA pipeline of an approval in the near future,” Dr. Khanna said.

The study was funded by Ferring Pharmaceuticals. Dr. Khanna reported receiving grant and research funding from Ferring. Dr. Malter reported no relevant financial relationships.

In the era of Ebola, COVID-19, and even Legionnaires, technicians and other staff working behind the scenes to ensure provider and patient safety continue to face a long-recognized but under addressed challenge: splashes and airborne droplets.

Granted, National Institute for Occupational Safety and Health (NIOSH) standards, industry standards, and professional guidelines are all in place to prevent unintentional exposure to pathogens. However, findings from a newly published study in the American Journal of Infection Control suggest they fall short.

In the study, researchers found that simulated manual cleaning of medical devices generated a drenching splash throughout the process with droplet dispersal exceeding 7 feet (2.1 meters).

“The guidelines say that droplets stop at 3 or 4 feet, and they don’t,” Cori L. Ofstead, MSPH, lead author and president/CEO of Ofstead & Associates, Bloomington, Minn., told this news organization. “That’s the problem with having standards and guidelines that are not based on relevant evidence, [which] in this case, is a single study that was done in an intensive care area where they had an infection outbreak.”

Ms. Ofstead was referring to a report in the journal Infection Control and Hospital Epidemiology, detailing a Canadian investigation involving a multidrug-resistant Pseudomonas aeruginosa outbreak in an ICU. The report implicated the faucets over the hand hygiene sinks, with fluorescent dye showing droplet dispersal roughly 3 feet away from the sinks.

“Somehow it [the 3-feet rule] got implemented in guidelines in sterile processing decontamination areas, which are not the same as hand hygiene,’’ Ms. Ofstead explained.

With a goal of providing more current evidence on droplet generation and dispersal, as well as personal protection equipment (PPE) exposure/effectiveness, she and her colleagues simulated manual cleaning of a decommissioned colonoscope and transvaginal ultrasound probe, using for the study location a new academic sterile processing unit.

To detect droplet generation and dispersal as well as splash following common technician activities (for example, colonoscope brushing, scrubbing, rinsing and transport to an automated endoscope reprocessor [AER] for sterilization), the researchers affixed blue moisture-detection paper to environmental surfaces, on carts positioned 4 feet (1.2 meters) from the sink (to simulate observers), and along a 15-foot pathway between the sink and AER.

They observed droplets everywhere.

Technician activities such as running the faucet and rinsing the probe under running water generated substantial splashing overall. Instrument rinsing in particular produced small and large droplets and confluent puddles of water around the sink and in the broad area surrounding the workspace. Droplets were also dispersed on the floor 7.25 feet (2.2 meters) away and along the entire 15-foot path from the sink to the AER.

At the sink, the technician risked drenching exposure from head to toe during most activities, and even observers positioned 3-4 feet away were found to have droplets on their gowns. In addition, saturated shoe covers reportedly tracked moisture away from the sink to the unit door – a distance of 13 feet (4 meters) – and 2 feet (0.6 meters) farther out into the PPE foyer for donning and doffing.

Although PPE gowns effectively repelled moisture during cleaning of a single device, Ms. Ofstead emphasized that technicians typically handle up to 10 instruments during a normal, 2-hour shift, further increasing exposure risk with each subsequent cleaning.

However, perhaps one of the most surprising findings was that despite an optimal unit design, including physical separation of clean and dirty activities and pressurized air flow to protect workers, droplets were still broadly dispersed.

Current efforts, however well-intentioned, might not be offering the degree of protection (and consideration) that sterile processing technicians need.

“The study was conducted in a new sterile processing area that had an extra excellent kind of distancing and three separate rooms, something that I think most of our hospitals are working toward,” Stella Hines, MD, associate professor at the University of Maryland School of Medicine, Baltimore, explained. Dr. Hines was not directly involved in the study.

“But it also really kind of highlighted what’s happening to workers potentially,” she added. “For example, we want to know if that spray or splatter has a live microbe it in that could cause a problem or ... in a highly wet environment, if that water has some kind of chemical in it that could pose an occupational hazard to the worker based on skin or mucous membrane exposure.”

Ms. Ofstead agreed. “We need to be thinking about the exposure of critically important workers and the environment in an era where we are worried about aerosol-generating procedures and superbugs,” she explained.

Dr. Hines and Ms. Ofstead also noted that the majority of staff involved in front-line patient care have never actually ventured into the sterile processing units nor do they recognize the risks that technicians working in these units face on a daily, or even hourly, basis.

“The people who run these operations are very well trained and knowledgeable. I think that it would be helpful for them to know that they’re appreciated and for the people upstairs on the front lines using the equipment to see what goes on downstairs and all of the painstaking steps that need to be in place for the equipment to come out of sterile processing and be ready to go,” said Dr. Hines.

In the meantime, hospital leaders need to address the challenges and danger posed by migrating infectious droplets, especially for workers involved in processes that stir them up in the first place – workers who by the end of their shifts are unavoidably drenched with infectious blood and tissue secretions.

“I think that it’s going to take a much bigger kind of worldview from hospital leadership,” Dr. Hines said.

The study was supported in part by a grant from Healthmark Industries. Ms. Ofstead reports research grants or consulting fees through her organization with 3M Company, Ambu, Boston Scientific, Cleanis, Fortive/Advanced Sterilization Products, Healthmark Industries, Pentax, and Steris/Cantel/Medviators. Dr. Hines reports no relevant financial relationships.

In the era of Ebola, COVID-19, and even Legionnaires, technicians and other staff working behind the scenes to ensure provider and patient safety continue to face a long-recognized but under addressed challenge: splashes and airborne droplets.

Granted, National Institute for Occupational Safety and Health (NIOSH) standards, industry standards, and professional guidelines are all in place to prevent unintentional exposure to pathogens. However, findings from a newly published study in the American Journal of Infection Control suggest they fall short.

In the study, researchers found that simulated manual cleaning of medical devices generated a drenching splash throughout the process with droplet dispersal exceeding 7 feet (2.1 meters).

“The guidelines say that droplets stop at 3 or 4 feet, and they don’t,” Cori L. Ofstead, MSPH, lead author and president/CEO of Ofstead & Associates, Bloomington, Minn., told this news organization. “That’s the problem with having standards and guidelines that are not based on relevant evidence, [which] in this case, is a single study that was done in an intensive care area where they had an infection outbreak.”

Ms. Ofstead was referring to a report in the journal Infection Control and Hospital Epidemiology, detailing a Canadian investigation involving a multidrug-resistant Pseudomonas aeruginosa outbreak in an ICU. The report implicated the faucets over the hand hygiene sinks, with fluorescent dye showing droplet dispersal roughly 3 feet away from the sinks.

“Somehow it [the 3-feet rule] got implemented in guidelines in sterile processing decontamination areas, which are not the same as hand hygiene,’’ Ms. Ofstead explained.

With a goal of providing more current evidence on droplet generation and dispersal, as well as personal protection equipment (PPE) exposure/effectiveness, she and her colleagues simulated manual cleaning of a decommissioned colonoscope and transvaginal ultrasound probe, using for the study location a new academic sterile processing unit.

To detect droplet generation and dispersal as well as splash following common technician activities (for example, colonoscope brushing, scrubbing, rinsing and transport to an automated endoscope reprocessor [AER] for sterilization), the researchers affixed blue moisture-detection paper to environmental surfaces, on carts positioned 4 feet (1.2 meters) from the sink (to simulate observers), and along a 15-foot pathway between the sink and AER.

They observed droplets everywhere.

Technician activities such as running the faucet and rinsing the probe under running water generated substantial splashing overall. Instrument rinsing in particular produced small and large droplets and confluent puddles of water around the sink and in the broad area surrounding the workspace. Droplets were also dispersed on the floor 7.25 feet (2.2 meters) away and along the entire 15-foot path from the sink to the AER.

At the sink, the technician risked drenching exposure from head to toe during most activities, and even observers positioned 3-4 feet away were found to have droplets on their gowns. In addition, saturated shoe covers reportedly tracked moisture away from the sink to the unit door – a distance of 13 feet (4 meters) – and 2 feet (0.6 meters) farther out into the PPE foyer for donning and doffing.

Although PPE gowns effectively repelled moisture during cleaning of a single device, Ms. Ofstead emphasized that technicians typically handle up to 10 instruments during a normal, 2-hour shift, further increasing exposure risk with each subsequent cleaning.

However, perhaps one of the most surprising findings was that despite an optimal unit design, including physical separation of clean and dirty activities and pressurized air flow to protect workers, droplets were still broadly dispersed.

Current efforts, however well-intentioned, might not be offering the degree of protection (and consideration) that sterile processing technicians need.

“The study was conducted in a new sterile processing area that had an extra excellent kind of distancing and three separate rooms, something that I think most of our hospitals are working toward,” Stella Hines, MD, associate professor at the University of Maryland School of Medicine, Baltimore, explained. Dr. Hines was not directly involved in the study.

“But it also really kind of highlighted what’s happening to workers potentially,” she added. “For example, we want to know if that spray or splatter has a live microbe it in that could cause a problem or ... in a highly wet environment, if that water has some kind of chemical in it that could pose an occupational hazard to the worker based on skin or mucous membrane exposure.”

Just when we thought this holiday season, finally, would be the back-to-normal one, some infectious disease experts are warning that a so-called “tripledemic” – influenza, COVID-19, and RSV – may be in the forecast.

The warning isn’t without basis. 

The flu season has gotten an early start. As of Oct. 21, early increases in seasonal flu activity have been reported in most of the country, the Centers for Disease Control and Prevention said, with the southeast and south-central areas having the highest activity levels. 

Children’s hospitals and EDs are seeing a surge in children with RSV.

COVID-19 cases are trending down, according to the CDC, but epidemiologists – scientists who study disease outbreaks – always have their eyes on emerging variants. 

Predicting exactly when cases will peak is difficult, said Justin Lessler, PhD, a professor of epidemiology at the University of North Carolina at Chapel Hill. Dr. Lessler is on the coordinating team for the COVID-19 Scenario Modeling Hub, which aims to predict the course COVID-19, and the Flu Scenario Modeling Hub, which does the same for influenza.

For COVID-19, some models are predicting some spikes before Christmas, he said, and others see a new wave in 2023. For the flu, the model is predicting an earlier-than-usual start, as the CDC has reported.  

While flu activity is relatively low, the CDC said, the season is off to an early start. For the week ending Oct. 21, 1,674 patients were hospitalized for flu, higher than in the summer months but fewer than the 2,675 hospitalizations for the week of May 15, 2022. 

As of Oct. 20, COVID-19 cases have declined 12% over the last 2 weeks, nationwide. But hospitalizations are up 10% in much of the Northeast, The New York Times reports, and the improvement in cases and deaths has been slowing down. 

As of Oct. 15, 15% of RSV tests reported nationwide were positive, compared with about 11% at that time in 2021, the CDC said. The surveillance collects information from 75 counties in 12 states. 

Experts point out that the viruses – all three are respiratory viruses – are simply playing catchup. 

“They spread the same way and along with lots of other viruses, and you tend to see an increase in them during the cold months,” said Timothy Brewer, MD, professor of medicine and epidemiology at UCLA.

The increase in all three viruses “is almost predictable at this point in the pandemic,” said Dean Blumberg, MD, a professor and chief of pediatric infectious diseases at the University of California Davis Health. “All the respiratory viruses are out of whack.” 

Last year, RSV cases were up, too, and began to appear very early, he said, in the summer instead of in the cooler months. Flu also appeared early in 2021, as it has in 2022. 

That contrasts with the flu season of 2020-2021, when COVID precautions were nearly universal, and cases were down. At UC Davis, “we didn’t have one pediatric admission due to influenza in the 2020-2021 [flu] season,” Dr. Blumberg said. 

The number of pediatric flu deaths usually range from 37 to 199 per year, according to CDC records. But in the 2020-2021 season, the CDC recorded one pediatric flu death in the U.S.

Both children and adults have had less contact with others the past two seasons, Dr. Blumberg said, “and they don’t get the immunity they got with those infections [previously]. That’s why we are seeing out-of-season, early season [viruses].” 

Eventually, he said, the cases of flu and RSV will return to previous levels. “It could be as soon as next year,” Dr. Blumberg said. And COVID-19, hopefully, will become like influenza, he said.

“RSV has always come around in the fall and winter,” said Elizabeth Murray, DO, a pediatric emergency medicine doctor at the University of Rochester (N.Y.) Medical Center and a spokesperson for the American Academy of Pediatrics. In 2022, children are back in school and for the most part not masking. “It’s a perfect storm for all the germs to spread now. They’ve just been waiting for their opportunity to come back.”
 

Self-care vs. not

RSV can pose a risk for anyone, but most at risk are children under age 5, especially infants under age 1, and adults over age 65. There is no vaccine for it. Symptoms include a runny nose, decreased appetite, coughing, sneezing, fever, and wheezing. But in young infants, there may only be decreased activity, crankiness, and breathing issues, the CDC said.

Keep an eye on the breathing if RSV is suspected, Dr. Murray tells parents. If your child can’t breathe easily, is unable to lie down comfortably, can’t speak clearly, or is sucking in the chest muscles to breathe, get medical help. Most kids with RSV can stay home and recover, she said, but often will need to be checked by a medical professional.

She advises against getting an oximeter to measure oxygen levels for home use. “They are often not accurate,” she said. If in doubt about how serious your child’s symptoms are, “don’t wait it out,” and don’t hesitate to call 911.

Symptoms of flu, COVID, and RSV can overlap. But each can involve breathing problems, which can be an emergency. 

“It’s important to seek medical attention for any concerning symptoms, but especially severe shortness of breath or difficulty breathing, as these could signal the need for supplemental oxygen or other emergency interventions,” said Mandy De Vries, a respiratory therapist and director of education at the American Association for Respiratory Care. Inhalation treatment or mechanical ventilation may be needed for severe respiratory issues.
 

Precautions

To avoid the tripledemic – or any single infection – Timothy Brewer, MD, a professor of medicine and epidemiology at the University of California, Los Angeles, suggests some familiar measures: “Stay home if you’re feeling sick. Make sure you are up to date on your vaccinations. Wear a mask indoors.”

A new study provides more evidence that HPV infection doesn’t raise the risk of poor outcomes in women who undergo fertility treatment via in vitro fertilization with fresh embryos. In fact, HPV-positive women were somewhat more likely than HPV-negative women to become pregnant (relative risk, 1.20; 95% confidence interval, 1.03-1.39) and have live births (RR, 1.39; 95% CI, 1.13-1.70), researchers reported Oct. 24 at the American Society for Reproductive Medicine’s 2022 meeting .

“This evidence should reassure women that being HPV positive will not affect live birth rates after a fresh embryo transfer cycle,” said study coauthor and ob.gyn. Nina Vyas, MD, a clinical fellow at Weill Cornell Medicine, New York, in an interview.

According to Dr. Vyas, previous studies have offered conflicting results about whether HPV affects pregnancy outcomes. In 2006, for example, her group performed a pilot study (Fertil Steril. Jun 16. doi: 10.1016/j.fertnstert.2006.01.051) that linked lower pregnancy rates to HPV-positive tests on the day of egg retrieval.

“We sought to reevaluate this finding in a retrospective manner,” Dr. Vyas said. “You’re taking eggs out of their home, injecting with sperm, and putting them back. There’s so much that we don’t know, and we want to make sure there’s no extra risk.”

Also, she added, “prior studies had a relatively low sample size. We sought to use our patient volume to address this question on a larger scale. Our current study benefits from a large sample size and using the clinically meaningful endpoint of live birth as our primary outcome.”

For the new study, researchers retrospectively analyzed 1,333 patients (of 2,209 screened) who received first fresh embryo transfers from 2017 to 2019. All had cytology or HPV status documented per cervical cancer screening guidelines within 6 months before embryos were transferred.

The researchers looked at only fresh embryo transfers “so we could account for pregnancy outcomes closest to the documented HPV status at the time of egg retrieval,” Dr. Vyas said.

Ten percent (133) of patients were HPV positive. Of those, 60.1% became pregnant, and 43.6% of them had live births. Of the HPV-negative women (90% of subjects, n = 1,200), 52.2% became pregnant and 33.5% had live births. The researchers didn’t calculate P values, but Dr. Vyas said an analysis determined that the differences between HPV-positive and HPV-negative women were statistically significant.

The study size doesn’t allow researchers to determine whether HPV actually has a protective effect on pregnancy/live birth rates in IVF, Dr. Vyas said. Even if it did, the virus is dangerous.

What else could explain the discrepancy? “Some elements driving this could the smaller sample size of the HPV-positive group, differences in HPV prevalence between the general population and our population,” she said, “or other confounding factors we were not able to appreciate due to the limitations of the retrospective study.”

Researchers also reported that they found “no significant difference in biochemical or spontaneous abortion rates” between HPV-positive and HPV-negative women.

What is the message of the study? “Women with HPV can rest assured that they won’t have worse outcomes than their non-HPV [infected] counterparts after a fresh embryo transfer cycle,” Dr. Vyas said.

In an interview, McGill University, Montreal, epidemiologist Helen Trottier, PhD, MSc, noted that she recently coauthored a study that linked persistent HPV infection in pregnancy to premature births. The findings appear convincing, she said: “I think we can say that HPV is associated with preterm birth.”

She praised the new study but noted “the relative risks that are reported need to be adjusted for race and possibly other factors.”

Dr. Vyas said that kind of adjustment will occur in a future study that’s in progress. “We are now prospectively enrolling patients and collecting cytology data to understand whether there might be a difference for women with higher malignancy potential/different types of HPV genotypes.”

A new study provides more evidence that HPV infection doesn’t raise the risk of poor outcomes in women who undergo fertility treatment via in vitro fertilization with fresh embryos. In fact, HPV-positive women were somewhat more likely than HPV-negative women to become pregnant (relative risk, 1.20; 95% confidence interval, 1.03-1.39) and have live births (RR, 1.39; 95% CI, 1.13-1.70), researchers reported Oct. 24 at the American Society for Reproductive Medicine’s 2022 meeting .

“This evidence should reassure women that being HPV positive will not affect live birth rates after a fresh embryo transfer cycle,” said study coauthor and ob.gyn. Nina Vyas, MD, a clinical fellow at Weill Cornell Medicine, New York, in an interview.

According to Dr. Vyas, previous studies have offered conflicting results about whether HPV affects pregnancy outcomes. In 2006, for example, her group performed a pilot study (Fertil Steril. Jun 16. doi: 10.1016/j.fertnstert.2006.01.051) that linked lower pregnancy rates to HPV-positive tests on the day of egg retrieval.

“We sought to reevaluate this finding in a retrospective manner,” Dr. Vyas said. “You’re taking eggs out of their home, injecting with sperm, and putting them back. There’s so much that we don’t know, and we want to make sure there’s no extra risk.”

Also, she added, “prior studies had a relatively low sample size. We sought to use our patient volume to address this question on a larger scale. Our current study benefits from a large sample size and using the clinically meaningful endpoint of live birth as our primary outcome.”

For the new study, researchers retrospectively analyzed 1,333 patients (of 2,209 screened) who received first fresh embryo transfers from 2017 to 2019. All had cytology or HPV status documented per cervical cancer screening guidelines within 6 months before embryos were transferred.

The researchers looked at only fresh embryo transfers “so we could account for pregnancy outcomes closest to the documented HPV status at the time of egg retrieval,” Dr. Vyas said.

Ten percent (133) of patients were HPV positive. Of those, 60.1% became pregnant, and 43.6% of them had live births. Of the HPV-negative women (90% of subjects, n = 1,200), 52.2% became pregnant and 33.5% had live births. The researchers didn’t calculate P values, but Dr. Vyas said an analysis determined that the differences between HPV-positive and HPV-negative women were statistically significant.
