Switching patients with HIV from a protease inhibitor–based antiretroviral therapy regimen to an integrase inhibitor–based regimen can be performed safely, with maintenance of high levels of virologic suppression and improvements in both bone mineral density and renal function biomarkers, data from a randomized trial indicate.

Among 212 women with successful HIV virologic suppression following 48 weeks of treatment with ritonavir-boosted atazanavir plus tenofovir disoproxil fumarate (ATV/r +TDF), among those who were switched to continued therapy with an integrase inhibitor–based regimen of elvitegravir/cobicistat/emtricitabine and tenofovir alafenamide (E/C/F/TAF), mean increases in lumbar spine bone mineral density (BMD) were greater and renal function was improved compared with patients who were maintained with ATV/r + TDF, reported Monica Thormann, MD, from Salvador B. Gautier Hospital in Santo Domingo, Dominican Republic, and colleagues at the HIV Glasgow drug therapy meeting, which was held online in 2020.

Although the E/C/F/TAF regimen was associated with a significantly greater increase in lipids, there was no significant change in the total cholesterol to high-density lipoprotein (HDL) cholesterol ratio.

The patients in the study had previously participated in a blinded randomized trial comparing the integrase inhibitor combination plus TDF with ATV/r + TDF in treatment-naive women.

In the current study, patients were randomly assigned in a 3:1 ratio to maintenance with either E/C/F/TAF (159 patients) or ATV/r + TDF (53 patients).

Forty-eight weeks after the switch, virologic suppression (to fewer than 50 copies/mL) was maintained among 94.3% of those on the integrase inhibitor–based regimen, compared with 86.8% of those on the protease inhibitor–based regimen. Virologic failure was seen in 1.9% of those on the integrase inhibitor–based regimen and in 3.8% of those on the protease inhibitor–based regimen.

In addition, virologic suppression below 20 c/mL at week 48 was more common among women maintained on E/C/F/TAF, at 84.9% vs 71.7% (P = .041). No treatment-emergent resistance was seen with either regimen.

As noted, there were higher mean percentage increases in BMD in the E/C/F/TAF group for both total hip and lumbar spine, but only the latter measure improved significantly in comparison with patients treated with ATV/r + TDF (2.82% vs 0%, P < .001).

Markers of renal tubule damage, including the beta-2 microglobulin to creatinine ratio and the rentinol-binding protein to creatinine ratio, were significantly improved with the integrase inhibitor regimen.

Increases in total cholesterol, LDL cholesterol, and HDL cholesterol were 27 vs 5 mg/dL, 16 vs 8 mg/dL, and 5 vs 0 mg/dL in each case comparing the integrase inhibitor–based regimen to the protease inhibitor–based regimen. All of those comparisons were statistically significant.

As noted, however, the total cholesterol to HDL cholesterol ratio was not significantly different between the treatment arms. The rate or initiation of lipid-modifying agents was 1.3% in the E/C/F/TAF group vs 0 in the ATV/r + TDF group, but this difference was not statistically significant.

“These data demonstrate that women who switch to an integrase inhibitor + TAF‐based regimen maintain high levels of virologic suppression with improvement in BMD and renal function biomarkers, as compared with those remaining on their ritonavir boosted atazanavir + TDF‐based regimen,” the authors wrote.

The combination of islatravir (ISL) and doravirine (DOR) maintains HIV-1 viral suppression for at least 96 weeks, according to new data.

ISL is a first-in-class nucleoside reverse transcriptase translocation inhibitor (NRTTI), Jean-Michel Molina, MD, PhD, of Saint‐Louis and Lariboisière Hospitals in Paris, explained at the annual HIV drug therapy meeting in Glasgow, Scotland. The randomized, double-blind, dose‐ranging trial compared ISL+DOR to a fixed‐dose combination of DOR, lamivudine, and tenofovir disoproxil fumarate (DOR/3TC/TDF) daily in 121 patients.

Patients in the ISL+DOR group initially received 0.25, 0.75, or 2.25 mg of ISL along with 100 mg of DOR and 200 mg of 3TC. Beginning at week 20, participants achieving HIV viral loads of 50 copies/mL or less discontinued 3TC but continued on their assigned dose of ISL+DOR for at least 24 weeks. At that point the investigators noted a greater number of discontinuations in the 2.25-mg group and settled on the 0.75-mg ISL dose. All patients in the ISL group were transitioned to that dose between weeks 60 and 72.

At week 96, 81.1% of the patients in the combined ISL group maintained viral loads <50 copies/mL, comparable to the 80.6% of those in the DOR/3TC/TDF group.

ISL+DOR appeared to be “well tolerated,” the investigators noted. They found drug-related adverse events in 7.8% of the patients in the ISL+DOR group compared with 22.6% of patients in the DOR/3TC/TDF group. In addition, among the 90 patients in the ISL+DOR group, no more than 5% of participants experienced any specific drug-related adverse event.

In pediatric Crohn’s disease, a Clostridioides difficile infection detected within the first year after diagnosis is associated with a shorter time to first bowel resection surgery, according to a study that included both a retrospective and prospective analysis. The researchers also found evidence that changes in methionine biosynthesis and depletion of beneficial bacteria may contribute to risk of surgery.

C. difficile infection (CDI) disproportionately affects individuals with inflammatory bowel disease (IBD). Pediatric IBD patients have a 34% risk of recurrent CDI infection, compared with 7.5% in the general population. Previous research found that adults with ulcerative colitis and CDI are at more risk of colectomy, but the finding has not been replicated in children.

In a study published in Inflammatory Bowel Diseases, researchers led by Jennifer Hellmann and Lee Denson of the University of Cincinnati conducted a single-center retrospective analysis of 75 pediatric Crohn’s disease patients. They also conducted a prospective study of 70 pediatric Crohn’s disease patients, using shotgun metagenome sequencing to examine the relationship between microbiota composition and C. difficile carriage or surgery history.

Nineteen percent of patients tested positive for C. difficile. Use of antibiotics was associated with C. difficile (odds ratio, 7.9; P = .02). Of patients who underwent C. difficile testing in the first year, 23 went on to have surgery: 21% who were C. difficile negative required surgery, compared with 67% of those who were positive (hazard ratio, 4.4; P = .0003). The mean time to surgery was 527 days for C. difficile–positive patients and 1,268 days for those who were negative.

A multivariate regression analysis on 54 patients with complete data sets showed that the presence of C. difficile was associated with increased risk of surgery (OR, 16.2; P = .0006). When the analysis was run on all 73 patients, using null value for missing data, the results were similar (OR, 9.17; P = .008).

Shotgun sequencing found that 47 of 114 bacterial species that were associated with the presence of C. difficile were also associated with prior surgery for Crohn’s disease. Species included some that may play a role in mucosal homeostasis, such as Bifidobacterium breve and several Alistipes and Ruminococcus species. That suggests that a reduction in the numbers of these taxa may be associated with C. difficile presence and surgical risk.

The researchers also found that methionine synthesis pathways were depressed in C. difficile–positive and surgery patients. Methionine may bolster antioxidant capacity and improve villus morphology. IBD patients with dysbiosis and those experiencing Crohn’s disease exacerbations have been shown to have decreased methionine pathway activity, suggesting methionine biosynthesis changes have clinical relevance.

The study was funded by the National Institutes of Health.

Vancomycin followed by fecal microbiota transplant (FMT) was associated with reduced Clostridioides difficile (C. diff)-related mortality in patients hospitalized with refractory severe or fulminant C. diff infection (CDI) at a single center. The improvements came after Indiana University implemented an FMT option in 2013.

About 8% of C. diff patients develop severe or fulminant CDI (SFCDI), which can lead to toxic colon and multiorgan failure. Surgery is the current recommended treatment for these patients if they are refractory to vancomycin, but 30-day mortality is above 40%. FMT is recommended for recurrent CDI, and it achieves cure rates greater than 80%, along with fewer relapses compared with anti-CDI antibiotic therapy.

FMT has been shown to be effective for SFCDI, with a 91% cure rate for serious CDI and 66% for fulminant CDI.

In the study published in the September issue of Clinical Gastroenterology and Hepatology, researchers led by Yao-Wen Cheng, MD, and Monika Fischer, MD, of Indiana University, assessed the effect of FMT on SFCDI after their institution adopted it as a treatment protocol for SFCDI. Patients could receive FMT if there was evidence that their SFCDI was refractory, or if they had two or more CDI recurrences. The treatment includes oral vancomycin and pseudomembrane-driven sequential FMT.

Two hundred five patients were admitted before FMT implementation, 225 after. Fifty patients received FMT because of refractory SFCDI. A median of two FMTs was conducted per patient. 21 other patients received FMT for nonrefractory SFCDI or other conditions, including 18 patients with multiple recurrent CDI.

Thirty-day CDI-related mortality dropped after FMT implementation (4.4% versus 10.2%; P =.02). This was true in both the fulminant subset (9.1% versus 21.3%; P =.015) and the refractory group (12.1% versus 43.2%; P < .001).

The researchers used segmented logistic regression to determine if the improved outcomes could be due to nontreatment factors that varied over time, and found that the difference in CDI-related mortality was eliminated except for refractory SFCDI patients (odds of mortality after FMT implementation, 0.09; P =.023). There was no significant difference between those receiving non-CDI antibiotics (4.8%) and those who did not (6.9%; P =.75).

FMT was associated with lower frequency of CDI-related colectomy overall (2.7% versus 6.8%; P =.041), as well as in the fulminant (5.5% versus 15.7%; P =.017) and refractory subgroups (7.6% versus 31.8%; P =.001).

The findings follow another study that showed improved 3-month mortality for FMT among patients hospitalized with severe CDI (12.1% versus 42.2%; P < .003).

The results underscore the utility of FMT for SFCDI, and suggest it might have the most benefit in refractory SFCDI. The authors believe that FMT should be an alternative to colectomy when first-line anti-CDI antibiotics are partially or completely ineffective. In the absence of FMT, patients who go on to fail vancomycin or fidaxomicin will likely continue to be managed medically, with up to 80% mortality, or through salvage colectomy, with postsurgical morality rates of 30-40%.

Although a randomized trial could answer the question of FMT efficacy more definitively, it is unlikely to be conducted for ethical reasons.

“Further investigation is required to clearly define FMT’s role and timing in the clinical course of severe and fulminant CDI. However, our study suggests that FMT should be offered to patients with severe and fulminant CDI who do not respond to a 5-day course of anti-CDI antibiotics and may be considered in lieu of or before colectomy,” the researchers wrote.

Vancomycin followed by fecal microbiota transplant (FMT) was associated with reduced Clostridioides difficile (C. diff)-related mortality in patients hospitalized with refractory severe or fulminant C. diff infection (CDI) at a single center. The improvements came after Indiana University implemented an FMT option in 2013.

About 8% of C. diff patients develop severe or fulminant CDI (SFCDI), which can lead to toxic colon and multiorgan failure. Surgery is the current recommended treatment for these patients if they are refractory to vancomycin, but 30-day mortality is above 40%. FMT is recommended for recurrent CDI, and it achieves cure rates greater than 80%, along with fewer relapses compared with anti-CDI antibiotic therapy.

FMT has been shown to be effective for SFCDI, with a 91% cure rate for serious CDI and 66% for fulminant CDI.

In the study published in the September issue of Clinical Gastroenterology and Hepatology, researchers led by Yao-Wen Cheng, MD, and Monika Fischer, MD, of Indiana University, assessed the effect of FMT on SFCDI after their institution adopted it as a treatment protocol for SFCDI. Patients could receive FMT if there was evidence that their SFCDI was refractory, or if they had two or more CDI recurrences. The treatment includes oral vancomycin and pseudomembrane-driven sequential FMT.

Two hundred five patients were admitted before FMT implementation, 225 after. Fifty patients received FMT because of refractory SFCDI. A median of two FMTs was conducted per patient. 21 other patients received FMT for nonrefractory SFCDI or other conditions, including 18 patients with multiple recurrent CDI.

Thirty-day CDI-related mortality dropped after FMT implementation (4.4% versus 10.2%; P =.02). This was true in both the fulminant subset (9.1% versus 21.3%; P =.015) and the refractory group (12.1% versus 43.2%; P < .001).

The researchers used segmented logistic regression to determine if the improved outcomes could be due to nontreatment factors that varied over time, and found that the difference in CDI-related mortality was eliminated except for refractory SFCDI patients (odds of mortality after FMT implementation, 0.09; P =.023). There was no significant difference between those receiving non-CDI antibiotics (4.8%) and those who did not (6.9%; P =.75).

FMT was associated with lower frequency of CDI-related colectomy overall (2.7% versus 6.8%; P =.041), as well as in the fulminant (5.5% versus 15.7%; P =.017) and refractory subgroups (7.6% versus 31.8%; P =.001).

The findings follow another study that showed improved 3-month mortality for FMT among patients hospitalized with severe CDI (12.1% versus 42.2%; P < .003).

The results underscore the utility of FMT for SFCDI, and suggest it might have the most benefit in refractory SFCDI. The authors believe that FMT should be an alternative to colectomy when first-line anti-CDI antibiotics are partially or completely ineffective. In the absence of FMT, patients who go on to fail vancomycin or fidaxomicin will likely continue to be managed medically, with up to 80% mortality, or through salvage colectomy, with postsurgical morality rates of 30-40%.

Although a randomized trial could answer the question of FMT efficacy more definitively, it is unlikely to be conducted for ethical reasons.

“Further investigation is required to clearly define FMT’s role and timing in the clinical course of severe and fulminant CDI. However, our study suggests that FMT should be offered to patients with severe and fulminant CDI who do not respond to a 5-day course of anti-CDI antibiotics and may be considered in lieu of or before colectomy,” the researchers wrote.

A 42-year-old woman with psoriasis presents for a checkup at the dermatology clinic. Her psoriasis has been fairly stable on methotrexate with no recent flares. She presents her concern of the coronavirus pandemic continuing into the flu season and mentions she would like to minimize her chances of having a respiratory illness. The influenza vaccine has just become available, and she inquires when she can get the vaccine and whether it will interfere with her treatment. What are your recommendations for the patient?

Psoriasis is an immune-mediated, inflammatory skin condition stemming from hyperproliferation of keratinocytes that classically involves erythematous skin plaques with overlying scale. Treatment options vary widely and include topical modalities, phototherapy, immunosuppressants, and biologic agents. Selection of treatment largely depends on the severity and extent of body surface area involvement; systemic therapy generally is indicated when the affected body surface area is greater than 5% to 10%. In patients on systemic therapy, increased susceptibility to infection is a priority concern for prescribing physicians. In the context of continuing immunosuppressive medications, vaccines that reduce susceptibility to infectious diseases can play an important role in reducing morbidity and mortality for these patients; however, an important consideration is that in patients with chronic conditions and frequent hospital visits, vaccines may be administered by various clinicians who may not be familiar with the management of immunosuppressive treatments. It is pivotal for prescribing dermatologists to provide appropriate vaccination instructions for the patient and any future clinicians to ensure vaccine efficacy in these patients.

The intramuscular influenza vaccine is a killed vaccine that is administered annually and has been shown to be safe for use in both immunocompetent and immunocompromised patients.^1,2 Despite its safety, questions remain regarding the efficacy of vaccines while a patient is unable to mount a normal immune response and whether the treatment must be altered to maximize immunogenicity. The common systemic treatment options for psoriasis and any recommendations that can be made regarding administration of the influenza vaccine in that context are outlined in the Table. Given the sparsity of clinical data measuring vaccine immunogenicity in patients with psoriasis, vaccine guidelines are drawn from patients with various conditions who are receiving the same dose of medication as indicated for psoriasis.

After 2 weeks of declines, the percentage of weekly COVID-19 cases occurring in children increased during the week ending Oct. 8, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

For the week, 14.6% of all COVID-19 cases reported in the United States occurred in children, after 2 consecutive weeks of declines that saw the proportion drop from 16.9% to 12.3%. The cumulative rate of child cases for the entire pandemic is 10.7%, with total child cases in the United States now up to 697,633 and cases among all ages at just over 6.5 million, the AAP and the CHA said Oct. 12 in their weekly COVID-19 report.

Nationally, there were 927 cases reported per 100,000 children as of Oct. 8, with rates at the state level varying from 176 per 100,000 in Vermont to 2,221 per 100,000 in North Dakota. Two other states were over 2,000 cases per 100,000 children: Tennessee (2,155) and South Carolina (2,116), based on data from the health departments of 49 states (New York does not report age distribution), as well as the District of Columbia, New York City, Puerto Rico, and Guam.

Severe illness continues to be rare in children, and national (25 states and New York City) hospitalization rates dropped in the last week. The proportion of hospitalizations occurring in children slipped from a pandemic high of 1.8% the previous week to 1.7% during the week of Oct. 8, and the rate of hospitalizations for children with COVID-19 was down to 1.4% from 1.6% the week before and 1.9% on Sept. 3, the AAP and the CHA said.

Mortality data from 42 states and New York City also show a decline. For the third consecutive week, children represented just 0.06% of all COVID-19 deaths in the United States, down from a high of 0.07% on Sept. 17. Only 0.02% of all cases in children have resulted in death, and that figure has been dropping since early June, when it reached 0.06%, according to the AAP/CHA report. As of Oct. 8, there have been 115 total deaths reported in children.

Unlike previous studies focused on vaccine effectiveness (VE) in ambulatory care office visits, Angela P. Campbell, MD, MPH, and associates have uncovered evidence of the overall benefit influenza vaccines play in reducing hospitalizations and emergency department visits in pediatric influenza patients.

“Our data provide important VE estimates against severe influenza in children,” the researchers noted in Pediatrics, adding that the findings “provide important evidence supporting the annual recommendation that all children 6 months and older should receive influenza vaccination.”

Dr. Campbell and colleagues collected ongoing surveillance data from the New Vaccine Surveillance Network (NVSN), which is a network of pediatric hospitals across seven cities, including Kansas City, Mo.; Rochester, N.Y.; Cincinnati; Pittsburgh; Nashville, Tenn.; Houston; and Seattle. The influenza season encompassed the period Nov. 7, 2018 to June 21, 2019.

A total of 2,748 hospitalized children and 2,676 children who had completed ED visits that did not lead to hospitalization were included. Once those under 6 months were excluded, 1,792 hospitalized children were included in the VE analysis; of these, 226 (13%) tested positive for influenza infection, including 211 (93%) with influenza A viruses and 15 (7%) with influenza B viruses. Fully 1,611 of the patients (90%), had verified vaccine status, while 181 (10%) had solely parental reported vaccine status. The researchers reported 88 (5%) of the patients received mechanical ventilation and 7 (<1%) died.

Most noteworthy, the researchers observed a significant reduction in laboratory-confirmed hospitalizations by 41% in children vaccinated against the flu. They further estimated a significant reduction in hospitalizations linked to A(H3N2) and A(H1N1)pdm09 viruses, even in the presence of circulating A(H3N2) viruses that differed from the A(H3N2) vaccine component.

Studies from other countries during the same time period showed that while “significant protection against influenza-associated ambulatory care visits and hospitalizations among children infected with A(H1N1)pdm09 viruses” was observed, the same could not be said for protection against A(H3N2) viruses, which varied among pediatric outpatients in the United States (24%), in England (17% outpatient; 31% inpatient), Europe (46%), and Canada (48%). They explained that such variation in vaccine protection is multifactorial, and includes virus-, host-, and environment-related factors. They also noted that regional variations in circulating viruses, host factors including age, imprinting, and previous vaccination could explain the study’s finding of vaccine protection against both A(H1N1)pdm09 and A(H3N2) viruses.

When comparing VE estimates between ED visits and hospitalizations, the researchers observed one significant difference, that “hospitalized children likely represent more medically complex patients, with 58% having underlying medical conditions and 38% reporting at lease one hospitalization in the past year, compared with 28% and 14% respectively, among ED participants.”

Strengths of the study included the prospective multisite enrollment that provided data across diverse locations and representation from pediatric hospitalizations and ED care, which were not previously strongly represented in the literature. The single-season study with small sample size was considered a limitation, as was the inability to evaluate full and partial vaccine status. Vaccine data also were limited for many of the ED patients observed.

Dr. Campbell and colleagues did caution that while they consider their test-negative design optimal for evaluating both hospitalized and ED patients, they feel their results should not be “interpreted as VE against influenza-associated ambulatory care visits or infections that are not medically attended.”

In a separate interview, Michael E. Pichichero, MD, director of the Rochester General Hospital Research Institute and a clinical professor of pediatrics at the University of Rochester (N.Y.), observed: “There are really no surprises here. A well done contemporary study confirms again the benefits of annual influenza vaccinations for children. Viral coinfections involving SARS-CoV-2 and influenza have been reported from Australia to cause heightened illnesses. That observation provides further impetus for parents to have their children receive influenza vaccinations.”

The researchers cited multiple sources of financial support for their ongoing work, including Sanofi, Quidel, Moderna, Karius, GlaxoSmithKline, Merck, AstraZeneca, and Pfizer. Funding for this study was supported by the Centers for Disease Control and Prevention. Dr. Pichichero said he had no relevant financial disclosures.

More than 225,000 excess deaths occurred in the United States from March to July 2020, compared with historic norms, with approximately two-thirds directly attributable to COVID-19. However, additional deaths could be indirectly related because people avoided emergency care during the pandemic, new research shows.

Deaths linked to COVID-19 varied by state and phase of the pandemic, as reported in a study from researchers at Virginia Commonwealth University and Yale University that was published online October 12 in JAMA.

Another study published online simultaneously in JAMA took more of an international perspective. Investigators from the University of Pennsylvania and Harvard University found that in America there were more excess deaths and there was higher all-cause mortality during the pandemic than in 18 other countries.

Although the ongoing number of deaths attributable to COVID-19 continues to garner attention, there can be a lag of weeks or months in how long it takes some public health agencies to update their figures.

“For the public at large, the take-home message is twofold: that the number of deaths caused by the pandemic exceeds publicly reported COVID-19 death counts by 20% and that states that reopened or lifted restrictions early suffered a protracted surge in excess deaths that extended into the summer,” lead author of the US-focused study, Steven H. Woolf, MD, MPH, told Medscape Medical News.

The take-away for physicians is in the bigger picture – it is likely that the COVID-19 pandemic is responsible for deaths from other conditions as well. “Surges in COVID-19 were accompanied by an increase in deaths attributed to other causes, such as heart disease and Alzheimer’s disease and dementia,” said Woolf, director emeritus and senior adviser at the Center on Society and Health and professor in the Department of Family Medicine and Population Health at the Virginia Commonwealth University School of Medicine in Richmond, Virginia.

The investigators identified 225,530 excess US deaths in the 5 months from March to July. They report that 67% were directly attributable to COVID-19.

Deaths linked to COVID-19 included those in which the disease was listed as an underlying or contributing cause. US total death rates are “remarkably consistent” year after year, and the investigators calculated a 20% overall jump in mortality.

The study included data from the National Center for Health Statistics and the US Census Bureau for 48 states and the District of Columbia. Connecticut and North Carolina were excluded because of missing data.

Woolf and colleagues also found statistically higher rates of deaths from two other causes, heart disease and Alzheimer’s disease/dementia.
 

Altered states

New York, New Jersey, Massachusetts, Louisiana, Arizona, Mississippi, Maryland, Delaware, Rhode Island, and Michigan had the highest per capita excess death rates. Three states experienced the shortest epidemics during the study period: New York, New Jersey, and Massachusetts.

Some lessons could be learned by looking at how individual states managed large numbers of people with COVID-19. “Although we suspected that states that reopened early might have put themselves at risk of a pandemic surge, the consistency with which that occurred and the devastating numbers of deaths they suffered was a surprise,” Woolf said.

“The goal of our study is not to look in the rearview mirror and lament what happened months ago but to learn the lesson going forward: Our country will be unable to take control of this pandemic without more robust efforts to control community spread,” Woolf said. “Our study found that states that did this well, such as New York and New Jersey, experienced large surges but bent the curve and were back to baseline in less than 10 weeks.

“If we could do this as a country, countless lives could be saved.”
 

A global perspective

The United States experienced high mortality linked to COVID-19, as well as high all-cause mortality, compared with 18 other countries, as reported in the study by University of Pennsylvania and Harvard University researchers.

The United States ranked third, with 72 deaths per 100,000 people, among countries with moderate or high mortality. Although perhaps not surprising given the state of SARS-CoV-2 infection across the United States, a question remains as to what extent the relatively high mortality rate is linked to early outbreaks vs “poor long-term response,” the researchers note.

Alyssa Bilinski, MSc, and lead author Ezekiel J. Emanuel, MD, PhD, chair of the Department of Medical Ethics and Health Policy at the University of Pennsylvania Perelman School of Medicine in Philadelphia, calculated the difference in COVID-19 deaths among countries through Sept. 19, 2020. On this date, the United States reported a total 198,589 COVID-19 deaths.

They calculated that, if the US death rates were similar to those in Australia, the United States would have experienced 187,661 fewer COVID-19 deaths. If similar to those of Canada, there would have been 117,622 fewer deaths in the United States.

The US death rate was lower than six other countries with high COVID-19 mortality in the early spring, including Belgium, Spain, and the United Kingdom. However, after May 10, the per capita mortality rate in the United States exceeded the others.

Between May 10 and Sept. 19, the death rate in Italy was 9.1 per 100,000, vs 36.9 per 100,000.

“After the first peak in early spring, US death rates from COVID-19 and from all causes remained higher than even countries with high COVID-19 mortality,” the researchers note. “This may have been a result of several factors, including weak public health infrastructure and a decentralized, inconsistent US response to the pandemic.”
 

“Mortifying and motivating”

Woolf and colleagues estimate that more than 225,000 excess deaths occurred in recent months; this represents a 20% increase over expected deaths, note Harvey V. Fineberg, MD, PhD, of the Gordon and Betty Moore Foundation, in an accompanying editorial in JAMA.

“Importantly, a condition such as COVID-19 can contribute both directly and indirectly to excess mortality,” he writes.

Although the direct contribution to the mortality rates by those infected is straightforward, “the indirect contribution may relate to circumstances or choices due to the COVID-19 pandemic: for example, a patient who develops symptoms of a stroke is too concerned about COVID-19 to go to the emergency department, and a potentially reversible condition becomes fatal.”

Fineberg notes that “a general indication of the death toll from COVID-19 and the excess deaths related to the pandemic, as presented by Woolf et al, are sufficiently mortifying and motivating.”
 

“Profound human toll”

“The importance of the estimate by Woolf et al – which suggests that for the entirety of 2020, more than 400,000 excess deaths will occur – cannot be overstated, because it accounts for what could be declines in some causes of death, like motor vehicle crashes, but increases in others, like myocardial infarction,” write Howard Bauchner, MD, editor in chief of JAMA, and Phil B. Fontanarosa, MD, MBA, executive editor of JAMA, in another accompanying editorial.

“These deaths reflect a true measure of the human cost of the Great Pandemic of 2020,” they add.

The study from Emanuel and Bilinski was notable for calculating the excess COVID-19 and all-cause mortality to Sept. 2020, they note. “After the initial peak in early spring, US death rates from COVID-19 and from all causes remained higher than rates in countries with high COVID-19 mortality.”

“Few people will forget the Great Pandemic of 2020, where and how they lived, how it substantially changed their lives, and for many, the profound human toll it has taken,” Bauchner and Fontanarosa write.

The study by Woolf and colleagues was supported by National Center for Advancing Translational Sciences, the National Institute on Aging, and the National Institute of Allergy and Infectious Diseases. The study by Bilinski and Emanuel was partially funded by the Colton Foundation. Woolf, Emanuel, Fineberg, Bauchner, and Fontanarosa have disclosed no relevant financial relationships.

More than 225,000 excess deaths occurred in the United States from March to July 2020, compared with historic norms, with approximately two-thirds directly attributable to COVID-19. However, additional deaths could be indirectly related because people avoided emergency care during the pandemic, new research shows.

Deaths linked to COVID-19 varied by state and phase of the pandemic, as reported in a study from researchers at Virginia Commonwealth University and Yale University that was published online October 12 in JAMA.

Another study published online simultaneously in JAMA took more of an international perspective. Investigators from the University of Pennsylvania and Harvard University found that in America there were more excess deaths and there was higher all-cause mortality during the pandemic than in 18 other countries.

Although the ongoing number of deaths attributable to COVID-19 continues to garner attention, there can be a lag of weeks or months in how long it takes some public health agencies to update their figures.

“For the public at large, the take-home message is twofold: that the number of deaths caused by the pandemic exceeds publicly reported COVID-19 death counts by 20% and that states that reopened or lifted restrictions early suffered a protracted surge in excess deaths that extended into the summer,” lead author of the US-focused study, Steven H. Woolf, MD, MPH, told Medscape Medical News.

The take-away for physicians is in the bigger picture – it is likely that the COVID-19 pandemic is responsible for deaths from other conditions as well. “Surges in COVID-19 were accompanied by an increase in deaths attributed to other causes, such as heart disease and Alzheimer’s disease and dementia,” said Woolf, director emeritus and senior adviser at the Center on Society and Health and professor in the Department of Family Medicine and Population Health at the Virginia Commonwealth University School of Medicine in Richmond, Virginia.

The investigators identified 225,530 excess US deaths in the 5 months from March to July. They report that 67% were directly attributable to COVID-19.

Deaths linked to COVID-19 included those in which the disease was listed as an underlying or contributing cause. US total death rates are “remarkably consistent” year after year, and the investigators calculated a 20% overall jump in mortality.

The study included data from the National Center for Health Statistics and the US Census Bureau for 48 states and the District of Columbia. Connecticut and North Carolina were excluded because of missing data.

Woolf and colleagues also found statistically higher rates of deaths from two other causes, heart disease and Alzheimer’s disease/dementia.
 

Altered states

New York, New Jersey, Massachusetts, Louisiana, Arizona, Mississippi, Maryland, Delaware, Rhode Island, and Michigan had the highest per capita excess death rates. Three states experienced the shortest epidemics during the study period: New York, New Jersey, and Massachusetts.

Human papillomavirus (HPV) is one of the most common sexually transmitted infections in the United States. It is the causative agent of genital warts, as well as cervical, anal, penile, vulvar, vaginal, and some head and neck cancers.¹ Development of the HPV vaccine and its introduction into the scheduled vaccine series recommended by the Centers for Disease Control and Prevention (CDC) represented a major public health milestone. The CDC recommends the HPV vaccine for all children beginning at 11 or 12 years of age, even as early as 9 years, regardless of gender identity or sexuality. As of late 2016, the 9-valent formulation (Gardasil 9 [Merck]) is the only HPV vaccine distributed in the United States, and the vaccination schedule depends specifically on age. The Advisory Committee on Immunization Practices (ACIP) of the CDC revised its recommendations in 2019 to include “shared clinical decision-making regarding HPV vaccination . . . for some adults aged 27 through 45 years.”² This change in policy has notable implications for sexual and gender minority populations, such as lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) patients, especially in the context of dermatologic care. Herein, we discuss HPV-related conditions for LGBTQ patients, barriers to vaccine administration, and the role of dermatologists in promoting an increased vaccination rate in the LGBTQ community.

HPV-Related Conditions

A 2019 review of dermatologic care for LGBTQ patients identified many specific health disparities of HPV.³ Specifically, men who have sex with men (MSM) are more likely than heterosexual men to have oral, anal, and penile HPV infections, including high-risk HPV types.³ From 2011 to 2014, 18% and 13% of MSM had oral HPV infection and high-risk oral HPV infection, respectively, compared to only 11% and 7%, respectively, of men who reported never having had a same-sex sexual partner.⁴

Similarly, despite the CDC’s position that patients with perianal warts might benefit from digital anal examination or referral for standard or high-resolution anoscopy to detect intra-anal warts, improvements in morbidity have not yet been realized. In 2017, anal cancer incidence was 45.9 cases for every 100,000 person-years among human immunodeficiency (HIV)–positive MSM and 5.1 cases for every 100,000 person-years among HIV-negative MSM vs only 1.5 cases for every 100,000 person-years among men in the United States overall.³ Yet the CDC states that there is insufficient evidence to recommend routine anal cancer screening among MSM, even when a patient is HIV positive. Therefore, current screening practices and treatments are insufficient as MSM continue to have a disproportionately higher rate of HPV-associated disease compared to other populations.

Barriers to HPV Vaccine Administration

The HPV vaccination rate among MSM in adolescent populations varies across reports.^5-7 Interestingly, a 2016 survey study found that MSM had approximately 2-times greater odds of initiating the HPV vaccine than heterosexual men.⁸ However, a study specifically sampling young gay and bisexual men (N=428) found that only 13% had received any doses of the HPV vaccine.⁶

Regardless, HPV vaccination is much less common among all males than it is among all females, and the low rate of vaccination among sexual minority men has a disproportionate impact, given their higher risk for HPV infection.⁴ Although the HPV vaccination rate increased from 2014 to 2017, the HPV vaccination rate in MSM overall is less than half of the Healthy People 2020 goal of 80%.⁹ A 2018 review determined that HPV vaccination is a cost-effective strategy for preventing anal cancer in MSM¹⁰; yet male patients might still view the HPV vaccine as a “women’s issue” and are less likely to be vaccinated if they are not prompted by health care providers. Additionally, HPV vaccination is remarkably less likely in MSM when patients are older, uninsured, of lower socioeconomic status, or have not disclosed their sexual identity to their health care provider.⁹ Dermatologists should be mindful of these barriers to promote HPV vaccination in MSM before, or soon after, sexual debut.

Other members of the LGBTQ community, such as women who have sex with women, face notable HPV-related health disparities and would benefit from increased vaccination efforts by dermatologists. Adolescent and young adult women who have sex with women are less likely than heterosexual adolescent and young adult women to receive routine Papanicolaou tests and initiate HPV vaccination, despite having a higher number of lifetime sexual partners and a higher risk for HPV exposure.¹¹ A 2015 survey study (N=3253) found that after adjusting for covariates, only 8.5% of lesbians and 33.2% of bisexual women and girls who had heard of the HPV vaccine had initiated vaccination compared to 28.4% of their heterosexual counterparts.¹¹ The HPV vaccine is an effective public health tool for the prevention of cervical cancer in these populations. A study of women aged 15 to 19 years in the HPV vaccination era (2007-2014) found significant (P<.05) observed population-level decreases in cervical intraepithelial neoplasia incidence across all grades.¹²

Transgender women also face a high rate of HPV infection, HIV infection, and other structural and financial disparities, such as low insurance coverage, that can limit their access to vaccination. Transgender men have a higher rate of HPV infection than cisgender men, and those with female internal reproductive organs are less likely to receive routine Papanicolaou tests. A 2018 survey study found that approximately one-third of transgender men and women reported initiating the HPV vaccination series,¹³ but further investigation is required to make balanced comparisons to cisgender patients.

The Role of the Dermatologist

Collectively, these disparities emphasize the need for increased involvement by dermatologists in HPV vaccination efforts for all LGBTQ patients. Adult patients may have concerns about ties of the HPV vaccine to drug manufacturers and the general safety of vaccination. For pediatric patients, parents/guardians also may be concerned about an assumed but not evidence-based increase in sexual promiscuity following HPV vaccination.¹⁴ These topics can be challenging to discuss, but dermatologists have the duty to be proactive and initiate conversation about HPV vaccination, as opposed to waiting for patients to express interest. Dermatologists should stress the safety of the vaccine as well as its potential to protect against multiple, even life-threatening diseases. Providers also can explain that the ACIP recommends catch-up vaccination for all individuals through 26 years of age, regardless of sexual orientation or gender identity.

With the ACIP having recently expanded the appropriate age range for HPV vaccination, we encourage dermatologists to engage in education and shared decision-making to ensure that adult patients with specific risk factors receive the HPV vaccine. Because the expanded ACIP recommendations are aimed at vaccination before HPV exposure, vaccination might not be appropriate for all LGBTQ patients. However, eliciting a sexual history with routine patient intake forms or during the clinical encounter ensures equal access to the HPV vaccine.

Greater awareness of HPV-related disparities and barriers to vaccination in LGBTQ populations has the potential to notably decrease HPV-associated mortality and morbidity. Increased involvement by dermatologists contributes to the efforts of other specialties in universal HPV vaccination, regardless of sexual orientation or gender identity—ideally in younger age groups, such that patients receive the vaccine prior to coitarche.

There are many ways that dermatologists can advocate for HPV vaccination. Those in a multispecialty or academic practice can readily refer patients to an associated internist, primary care physician, or vaccination clinic in the same building or institution. Dermatologists in private practice might be able to administer the HPV vaccine themselves or can advocate for patients to receive the vaccine at a local facility of the Department of Health or at a nonprofit organization, such as a Planned Parenthood center. Although pediatricians and family physicians remain front-line providers of these services, dermatologists represent an additional member of a patient’s care team, capable of advocating for this important intervention.

With the ACIP having recently expanded the appropriate age range for HPV vaccination, we encourage dermatologists to engage in education and shared decision-making to ensure that adult patients with specific risk factors receive the HPV vaccine. Because the expanded ACIP recommendations are aimed at vaccination before HPV exposure, vaccination might not be appropriate for all LGBTQ patients. However, eliciting a sexual history with routine patient intake forms or during the clinical encounter ensures equal access to the HPV vaccine.

Greater awareness of HPV-related disparities and barriers to vaccination in LGBTQ populations has the potential to notably decrease HPV-associated mortality and morbidity. Increased involvement by dermatologists contributes to the efforts of other specialties in universal HPV vaccination, regardless of sexual orientation or gender identity—ideally in younger age groups, such that patients receive the vaccine prior to coitarche.

There are many ways that dermatologists can advocate for HPV vaccination. Those in a multispecialty or academic practice can readily refer patients to an associated internist, primary care physician, or vaccination clinic in the same building or institution. Dermatologists in private practice might be able to administer the HPV vaccine themselves or can advocate for patients to receive the vaccine at a local facility of the Department of Health or at a nonprofit organization, such as a Planned Parenthood center. Although pediatricians and family physicians remain front-line providers of these services, dermatologists represent an additional member of a patient’s care team, capable of advocating for this important intervention.

Human papillomavirus (HPV) is one of the most common sexually transmitted infections in the United States. It is the causative agent of genital warts, as well as cervical, anal, penile, vulvar, vaginal, and some head and neck cancers.¹ Development of the HPV vaccine and its introduction into the scheduled vaccine series recommended by the Centers for Disease Control and Prevention (CDC) represented a major public health milestone. The CDC recommends the HPV vaccine for all children beginning at 11 or 12 years of age, even as early as 9 years, regardless of gender identity or sexuality. As of late 2016, the 9-valent formulation (Gardasil 9 [Merck]) is the only HPV vaccine distributed in the United States, and the vaccination schedule depends specifically on age. The Advisory Committee on Immunization Practices (ACIP) of the CDC revised its recommendations in 2019 to include “shared clinical decision-making regarding HPV vaccination . . . for some adults aged 27 through 45 years.”² This change in policy has notable implications for sexual and gender minority populations, such as lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) patients, especially in the context of dermatologic care. Herein, we discuss HPV-related conditions for LGBTQ patients, barriers to vaccine administration, and the role of dermatologists in promoting an increased vaccination rate in the LGBTQ community.

HPV-Related Conditions

A 2019 review of dermatologic care for LGBTQ patients identified many specific health disparities of HPV.³ Specifically, men who have sex with men (MSM) are more likely than heterosexual men to have oral, anal, and penile HPV infections, including high-risk HPV types.³ From 2011 to 2014, 18% and 13% of MSM had oral HPV infection and high-risk oral HPV infection, respectively, compared to only 11% and 7%, respectively, of men who reported never having had a same-sex sexual partner.⁴

Similarly, despite the CDC’s position that patients with perianal warts might benefit from digital anal examination or referral for standard or high-resolution anoscopy to detect intra-anal warts, improvements in morbidity have not yet been realized. In 2017, anal cancer incidence was 45.9 cases for every 100,000 person-years among human immunodeficiency (HIV)–positive MSM and 5.1 cases for every 100,000 person-years among HIV-negative MSM vs only 1.5 cases for every 100,000 person-years among men in the United States overall.³ Yet the CDC states that there is insufficient evidence to recommend routine anal cancer screening among MSM, even when a patient is HIV positive. Therefore, current screening practices and treatments are insufficient as MSM continue to have a disproportionately higher rate of HPV-associated disease compared to other populations.

Barriers to HPV Vaccine Administration

The HPV vaccination rate among MSM in adolescent populations varies across reports.^5-7 Interestingly, a 2016 survey study found that MSM had approximately 2-times greater odds of initiating the HPV vaccine than heterosexual men.⁸ However, a study specifically sampling young gay and bisexual men (N=428) found that only 13% had received any doses of the HPV vaccine.⁶

Regardless, HPV vaccination is much less common among all males than it is among all females, and the low rate of vaccination among sexual minority men has a disproportionate impact, given their higher risk for HPV infection.⁴ Although the HPV vaccination rate increased from 2014 to 2017, the HPV vaccination rate in MSM overall is less than half of the Healthy People 2020 goal of 80%.⁹ A 2018 review determined that HPV vaccination is a cost-effective strategy for preventing anal cancer in MSM¹⁰; yet male patients might still view the HPV vaccine as a “women’s issue” and are less likely to be vaccinated if they are not prompted by health care providers. Additionally, HPV vaccination is remarkably less likely in MSM when patients are older, uninsured, of lower socioeconomic status, or have not disclosed their sexual identity to their health care provider.⁹ Dermatologists should be mindful of these barriers to promote HPV vaccination in MSM before, or soon after, sexual debut.

Other members of the LGBTQ community, such as women who have sex with women, face notable HPV-related health disparities and would benefit from increased vaccination efforts by dermatologists. Adolescent and young adult women who have sex with women are less likely than heterosexual adolescent and young adult women to receive routine Papanicolaou tests and initiate HPV vaccination, despite having a higher number of lifetime sexual partners and a higher risk for HPV exposure.¹¹ A 2015 survey study (N=3253) found that after adjusting for covariates, only 8.5% of lesbians and 33.2% of bisexual women and girls who had heard of the HPV vaccine had initiated vaccination compared to 28.4% of their heterosexual counterparts.¹¹ The HPV vaccine is an effective public health tool for the prevention of cervical cancer in these populations. A study of women aged 15 to 19 years in the HPV vaccination era (2007-2014) found significant (P<.05) observed population-level decreases in cervical intraepithelial neoplasia incidence across all grades.¹²

Transgender women also face a high rate of HPV infection, HIV infection, and other structural and financial disparities, such as low insurance coverage, that can limit their access to vaccination. Transgender men have a higher rate of HPV infection than cisgender men, and those with female internal reproductive organs are less likely to receive routine Papanicolaou tests. A 2018 survey study found that approximately one-third of transgender men and women reported initiating the HPV vaccination series,¹³ but further investigation is required to make balanced comparisons to cisgender patients.

The Role of the Dermatologist

Collectively, these disparities emphasize the need for increased involvement by dermatologists in HPV vaccination efforts for all LGBTQ patients. Adult patients may have concerns about ties of the HPV vaccine to drug manufacturers and the general safety of vaccination. For pediatric patients, parents/guardians also may be concerned about an assumed but not evidence-based increase in sexual promiscuity following HPV vaccination.¹⁴ These topics can be challenging to discuss, but dermatologists have the duty to be proactive and initiate conversation about HPV vaccination, as opposed to waiting for patients to express interest. Dermatologists should stress the safety of the vaccine as well as its potential to protect against multiple, even life-threatening diseases. Providers also can explain that the ACIP recommends catch-up vaccination for all individuals through 26 years of age, regardless of sexual orientation or gender identity.

Case Report

A 50-year-old woman presented with a sore, tender, red lump on the right superior buttock of 5 months’ duration. Five months prior to presentation the patient used this area to attach the infusion set for an insulin pump, which was left in place for 7 days as opposed to the 2 or 3 days recommended by the device manufacturer. A firm, slightly tender lump formed, similar to prior scars that had developed from use of the insulin pump. However, the lump began to grow and get softer. It was intermittently warm and red. Although the area was sore and tender, she never had any major pain. She also denied any fever, malaise, or other systemic symptoms.

The patient indicated a medical history of type 1 diabetes mellitus diagnosed at 9 years of age; hypertension; asthma; gastroesophageal reflux disease; allergic rhinitis; migraine headaches; depression; hidradenitis suppurativa that resolved after surgical excision; and recurrent vaginal yeast infections, especially when taking antibiotics. She had a surgical history of hidradenitis suppurativa excision at the inguinal folds, bilateral carpal tunnel release, tubal ligation, abdominoplasty, and cholecystectomy. The patient’s current medications included insulin aspart, mometasone furoate, inhaled fluticasone, pantoprazole, cetirizine, spironolactone, duloxetine, sumatriptan, fluconazole, topiramate, and enalapril.

Physical examination revealed normal vital signs and the patient was afebrile. She had no swollen or tender lymph nodes. There was a 5.5×7.0-cm, soft, tender, erythematous subcutaneous mass with no visible punctum or overlying epidermal change on the right superior buttock (Figure 1). Based on the history and physical examination, the differential diagnosis included subcutaneous fat necrosis, epidermal inclusion cyst, and an abscess.

Comment

Achromobacter xylosoxidans is a nonfermentative, non–spore-forming, motile, gram-negative, aerobic, catalase-positive and oxidase-positive flagellate bacterium. It is an emerging pathogen that was first isolated in 1971 from patients with chronic otitis media.¹ Since its recognition, it has been documented to cause a variety of infections, including pneumonia, meningitis, osteomyelitis, endocarditis, and bacteremia, as well as abdominal, urinary tract, ocular, and skin and soft tissue infections.^2,3 Those affected usually are immunocompromised, have hematologic disorders, or have indwelling catheters.⁴ Strains of A xylosoxidans have shown resistance to multiple antibiotics including penicillins, cephalosporins, carbapenems, aminoglycosides, macrolides, fluoroquinolones, and TMP-SMX. Achromobacter xylosoxidans has been documented to form biofilms on plastics, including on contact lenses, urinary and intravenous catheters, and reusable tissue dispensers treated with disinfectant solution.^4-6 One study demonstrated that A xylosoxidans is even capable of biodegradation of plastic, using the plastic as its sole source of carbon.⁷

Our case illustrates an indolent infection with A xylosoxidans forming a granulomatous abscess at the site of an insulin pump that was left in place for 7 days in an immunocompetent patient. Although infections with A xylosoxidans in patients with urinary or intravenous catheters have been reported,⁴ our case is unique, as the insulin pump was the source of such an infection. It is possible that the subcutaneous focus of acellular material described on the pathology report represented a partially biodegraded piece of the insulin pump catheter that broke off and was serving as a nidus of infection for A xylosoxidans. Although multidrug resistance is common, the culture grown from our patient was susceptible to TMP-SMX, among other antibiotics. Our patient was treated successfully with surgical excision, drainage, and a 10-day course of TMP-SMX.

Conclusion

Health care providers should recognize A xylosoxidans as an emerging pathogen that is capable of forming biofilms on “disinfected” surfaces and medical products, especially plastics. Achromobacter xylosoxidans may be resistant to multiple antibiotics and can cause infections with various presentations.
