Clinician Reviews

HIV increases the risk for severe COVID-19 by 6% and the risk of dying of COVID-19 in the hospital by 30%, according to a report from the World Health Organization on COVID-19 outcomes among people living with HIV. The study primarily included people from South Africa but also some data from other parts of the world, including the United States.

However, the report, presented at the 11th IAS Conference on HIV Science (IAS 2021), couldn’t answer some crucial questions clinicians have been wondering about since the COVID-19 pandemic began. For example, was the increase in COVID risk a result of the presence of HIV or because of the immune compromise caused by untreated HIV?

The report didn’t include data on viral load or CD counts, both used to evaluate the health of a person’s immune system. On effective treatment, people living with HIV have a lifespan close to their HIV-negative peers. And effective treatment causes undetectable viral loads which, when maintained for 6 months or more, eliminates transmission of HIV to sexual partners.

What’s clear is that in people with HIV, as in people without HIV, older people, men, and people with diabetes, hypertension, or obesity had the worst outcomes and were most likely to die from COVID-19.

For David Malebranche, MD, MPH, an internal medicine doctor who provides primary care for people in Atlanta, and who was not involved in the study, the WHO study didn’t add anything new. He already recommends the COVID-19 vaccine for all of his patients, HIV-positive or not.

“We don’t have any information from this about the T-cell counts [or] the rates of viral suppression, which I think is tremendously important,” he told this news organization. “To bypass that and not include that in any of the discussion puts the results in a questionable place for me.”

The results come from the WHO Clinical Platform, which culls data from WHO member country surveillance as well as manual case reports from all over the world. By April 29, data on 268,412 people hospitalized with COVID-19 from 37 countries were reported to the platform. Of those, 22,640 people are from the U.S.

A total of 15,522 participants worldwide were living with HIV, 664 in the United States. All U.S. cases were reported from the New York City Health and Hospitals system, Henry Ford Hospital in Detroit, and BronxCare Health System in New York City. Almost all of the remaining participants lived in South Africa – 14,682 of the 15,522, or 94.5%.

Of the 15,522 people living with HIV in the overall group, 37.1% of participants were male, and their median age was 45 years. More than 1 in 3 (36.2%) were admitted with severe or critical COVID-19, and nearly one quarter – 23.1% – with a known outcome died. More than half had one or more chronic conditions, including those that themselves are associated with worse COVID-19 outcomes, such as hypertension (in 33.2% of the participants), diabetes (22.7%), and BMIs above 30 (16.9%). In addition, 8.9% were smokers, 6.6% had chronic pulmonary disease, and 4.3% had chronic heart disease.

After adjusting for those chronic conditions, age, and sex, people living with HIV had a 6% higher rate of severe or critical COVID-19 illness. When investigators adjusted the analysis additionally to differentiate outcomes based on not just the presence of comorbid conditions but the number of them a person had, that increased risk rose to 13%. HIV itself is a comorbid condition, though it wasn’t counted as one in this adjusted analysis.

It didn’t matter whether researchers looked at risk for severe outcomes or deaths after removing the significant co-occurring conditions or if they looked at number of chronic illnesses (aside from HIV), said Silvia Bertagnolio, MD, medical officer at the World Health Organization and co-author of the analysis.

“Both models show almost identical [adjusted odds ratios], meaning that HIV was independently significantly associated with severe/critical presentation,” she told this news organization.

As for death, the analysis showed that, overall, people living with HIV were 30% more likely to die of COVID-19 compared with those not living with HIV. And while this held true even when they adjusted the data for comorbidities, people with HIV were more likely to die if they were over age 65 (risk increased by 82%), male (risk increased by 21%), had diabetes (risk increased by 50%), or had hypertension (risk increased by 26%).

When they broke down the data by WHO region – Africa, Europe, the Americas – investigators found that the increased risk for death held true in Africa. But there were not enough data from the other regions to model mortality risk. What’s more, when they broke the data down by country and excluded South Africa, they found that the elevated risk for death in people living with HIV did not reach statistical significance. Dr. Bertagnolio said she suspects that the small sample sizes from other regions made it impossible to detect a difference, but one could still be present.

One thing conspicuously absent from the analysis was information on viral load, CD4 T-cell count, progression of HIV to AIDS, and whether individuals were in HIV care. The first three factors were not reported in the platform, and the fourth was available for 60% of participants but was not included in the analysis. Dr. Bertagnolio pointed out that, for those 60% of participants, 91.8% were on antiretroviral treatment (ART).

“The majority of patients come from South Africa, and we know that in South Africa, over 90% of people receiving ART are virologically suppressed,” she told this news organization. “So we could speculate that this effect persists despite the use of ART, in a population likely to be virally suppressed, although we cannot assess this with certainty through the data set we had.”

A much smaller study of 749 people living with HIV and diagnosed with SARS-CoV-2, also presented at the conference, found that detectable HIV viral load was significantly associated with a slightly higher risk of severe outcomes (P < .039), but CD4 counts less than 200 cells/mm³ was not (P = .15).

And although both Dr. Bertagnolio and conference organizers presented this data as proof that HIV increases the risk for poor COVID-19 outcomes, Dr. Malebranche isn’t so sure. He estimates that only about half his patients have received the COVID-19 vaccine. But this study is unlikely to make him forcefully recommend a COVID-19 vaccination with young, otherwise healthy, and undetectable people in his care who express particular concern about long-term effects of the vaccine. He also manages a lot of people with HIV who have undetectable viral loads and CD4 counts of up to 1,200 but are older, with diabetes, obesity, and high blood pressure. Those are the people he will target with stronger messages regarding the vaccine.

“The young patients who are healthy, virally suppressed, and doing well may very much argue with me, ‘I’m not going to push it,’ but I will bring it up on the next visit,” he said. The analysis “just helps reinforce in me that I need to have these conversations and be a little bit more persuasive to my older patients with comorbid conditions.”

Dr. Bertagnolio has disclosed no relevant financial relationships. Dr. Malebranche serves on the pre-exposure prophylaxis (PrEP) speakers bureau for Gilead Sciences and has consulted and advised for ViiV Healthcare. This study was funded by the World Health Organization.

Bicycle riding may help people with diabetes live longer, new research suggests.

NicolasMcComber/E+/Getty Images

Among more than 7,000 adults with diabetes in 10 Western European countries followed for about 15 years, those who cycled regularly were significantly less likely to die of any cause or of cardiovascular causes, even after accounting for differences in factors such as sex, age, educational level, diet, comorbidities, and other physical activities.

“The association between cycling and all-cause and CVD [cardiovascular disease] mortality in this study of person[s] with diabetes was of the same magnitude and direction as observed in the healthy population,” wrote Mathias Ried-Larsen, PhD, of the Centre for Physical Activity Research, Rigshospitalet, Copenhagen, and colleagues. The findings were published online July 19, 2021, in JAMA Internal Medicine.

In an accompanying Editor’s Note, JAMA Internal Medicine editor Rita F. Redberg, MD, and two deputy editors said that the new data add to previous studies showing benefits of cycling, compared with other physical activities. “The analysis from Ried-Larsen and colleagues strengthens the epidemiologic data on cycling and strongly suggests that it may contribute directly to longer and healthier lives,” they wrote.

Dr. Redberg, of the University of California, San Francisco, told this news organization: “I think the number of cyclists grew greatly during pandemic, when there was little auto traffic, and people did not want to take public transportation. Cities that add bike lanes, especially protected bike lanes, see an increase in cyclists. I think Americans can cycle more, would enjoy cycling more, and would live longer [by] cycling, to work and for pleasure.”

Dr. Redberg disclosed that she is “an avid cyclist and am currently on a bike ride in Glacier National Park. ... This group [Climate Ride] raises money for more bike lanes, promotes climate change awareness, has paid for solar panels at Glacier, and more.”

However, Dr. Redberg and colleagues also “recognize that cycling requires fitness, a good sense of balance, and the means to purchase a bicycle. We also understand that regular cycling requires living in an area where it is reasonably safe, and we celebrate the installation of more bike lanes, particularly protected lanes, in many cities around the world.”

But, despite the limitations of an observational study and possible selection bias of people who are able to cycle, “it is important to share this evidence for the potentially large health benefits of cycling, which almost surely generalize to persons without diabetes.”
 

Cycling tied to lower all-cause and CVD mortality

The prospective cohort study included 7,459 adults with diabetes from the European Prospective Investigation into Cancer and Nutrition. All were assessed during 1992-1998 and again in 1996-2011, with a mean follow-up of roughly 15 years. During that time, there were 1,673 deaths from all causes, with 811 attributed to CVD.

Compared with no cycling, those who reported any cycling had a 24% lower risk of death from any cause over a 5-year period, after adjustment for confounders and for other physical activity. The greatest risk reduction was seen in those who reported cycling between 150-299 minutes per week, particularly in CVD mortality.

In a subanalysis of 5,423 individuals with 10.7 years of follow-up, there were 975 all-cause deaths and 429 from CVD. Individuals who began or continued cycling during follow-up experienced reductions of about 35% for both all-cause and CVD mortality, compared with those who never cycled.

Dr. Redberg and colleagues added that “there are environmental benefits to increasing the use of cycling for commuting and other transport because cycling helps to decrease the adverse environmental and health effects of automobile exhaust.”

They concluded: “As avid and/or aspiring cyclists ourselves, we are sold on the mental and physical benefits of getting to work and seeing the world on two wheels, self-propelled, and think it is well worth a try.”

The study work was supported by the Health Research Fund of Instituto de Salud Carlos III; the Spanish regional governments of Andalucía, Asturias, Basque Country, Murcia, and Navarra; and the Catalan Institute of Oncology. The Centre for Physical Activity Research is supported by a grant from TrygFonden. Dr. Ried-Larsen reported personal fees from Novo Nordisk. Dr. Redberg reported receiving grants from Arnold Ventures; the Greenwall Foundation; and the National Heart, Lung, and Blood Institute.

In a subanalysis of 5,423 individuals with 10.7 years of follow-up, there were 975 all-cause deaths and 429 from CVD. Individuals who began or continued cycling during follow-up experienced reductions of about 35% for both all-cause and CVD mortality, compared with those who never cycled.

Dr. Redberg and colleagues added that “there are environmental benefits to increasing the use of cycling for commuting and other transport because cycling helps to decrease the adverse environmental and health effects of automobile exhaust.”

They concluded: “As avid and/or aspiring cyclists ourselves, we are sold on the mental and physical benefits of getting to work and seeing the world on two wheels, self-propelled, and think it is well worth a try.”

The study work was supported by the Health Research Fund of Instituto de Salud Carlos III; the Spanish regional governments of Andalucía, Asturias, Basque Country, Murcia, and Navarra; and the Catalan Institute of Oncology. The Centre for Physical Activity Research is supported by a grant from TrygFonden. Dr. Ried-Larsen reported personal fees from Novo Nordisk. Dr. Redberg reported receiving grants from Arnold Ventures; the Greenwall Foundation; and the National Heart, Lung, and Blood Institute.

Lower doses of linezolid in the BPaL drug regimen (bedaquiline, pretomanid, and linezolid) significantly reduce the adverse events associated with the treatment for patients with highly drug-resistant tuberculosis (TB) without compromising its high efficacy, new research shows.

“The ZeNix trial shows that reduced doses and/or shorter durations of linezolid appear to have high efficacy and improved safety,” said first author Francesca Conradie, MB, BCh, of the clinical HIV research unit, faculty of health sciences, University of Witwatersrand, Johannesburg, South Africa, in presenting the findings at the virtual meeting of the International AIDS Society conference.

As recently reported in the pivotal Nix-TB trial, the BPaL regimen yielded a 90% treatment success rate among people with highly drug-resistant forms of TB.

However, a 6-month regimen that included linezolid 1,200 mg resulted in toxic effects: 81% of patients in the study experienced peripheral neuropathy, and myelosuppression occurred in 48%. These effects often led to dose reductions or treatment interruption.

Adjustments in the dose of linezolid in the new ZeNix trial substantially reduced peripheral neuropathy to 13% and myelosuppression to 7%, with no significant reduction in the treatment response.

Importantly, the results were similar among patients with and those without HIV. This is of note because TB is the leading cause of death among patients with HIV.

“In the ZeNix trial, only 20% of patients were HIV infected, but in the [previous] Nix-TB trial, 30% were infected, so we have experience now in about 70 patients who were infected, and the outcomes were no different,” Dr. Conradie said in an interview.

Experts say the findings represent an important turn in the steep challenge of tackling highly resistant TB.

“In our opinion, these are exciting results that could change treatment guidelines for highly drug-resistant tuberculosis, with real benefits for the patients,” said Hendrik Streeck, MD, International AIDS Society cochair and director of the Institute of Virology and the Institute for HIV Research at the University Bonn (Germany), in a press conference.

Payam Nahid, MD, MPH, director of the Center for Tuberculosis at theUniversity of California, San Francisco, agreed.

“The results of this trial will impact global practices in treating drug-resistant TB as well as the design and conduct of future TB clinical trials,” Dr. Nahid said in an interview.
 

ZeNix trial

The phase 3 ZeNix trial included 181 patients with highly resistant TB in South Africa, Russia, Georgia, and Moldova. The mean age of the patients was 37 years; 67.4% were men, 63.5% were White, and 19.9% were HIV positive.

All patients were treated for 6 months with bedaquiline 200 mg daily for 8 weeks followed by 100 mg daily for 18 weeks, as well as pretomanid 200 mg daily.

The patients were randomly assigned to receive one of four daily doses of linezolid: 1,200 mg for 6 months (the original dose from the Nix-TB trial; n = 45) or 2 months (n = 46), or 600 mg for 6 or 2 months (45 patients each).

Percentages of patients with HIV were equal among the four groups, at about 20% each.

The primary outcomes – resolution of clinical disease and a negative culture status after 6 months – were observed across all linezolid dose groups. The success rate was 93% for those receiving 1,200 mg for 6 months, 89% for those receiving 1,200 mg for 2 months, 91% for those receiving 600 mg for 6 months, and 84% for those receiving 600 mg for 2 months.

With regard to the key adverse events of peripheral neuropathy and myelosuppression, manifested as anemia, the highest rates were among those who received linezolid 1,200 mg for 6 month, at 38% and 22%, respectively, compared with 24% and 17.4% among those who received 1,200 mg for 2 months, 24% and 2% among those who received 600 mg for 6 months, and 13% and 6.7% among those who received 600 mg for 2 months.

Four cases of optic neuropathy occurred among those who received 1,200 mg for 6 months; all cases resolved.

Patients who received 1,200 mg for 6 months required the highest number of linezolid dose modifications; 51% required changes that included reduction, interruption, or discontinuation, compared with 28% among those who received 1,200 mg for 2 months and 13% each in the other two groups.

On the basis of these results, “my personal opinion is that 600 mg at 6 months [of linezolid] is most likely the best strategy for the treatment of this highly resistant treatment population group,” Dr. Conradie told this news organization.
 

Findings represent ‘great news’ in addressing concerns

Dr. Nahid further commented that the results are highly encouraging in light of the ongoing concerns about the effects of linezolid in the BPaL regimen.

“This is great news,” he said. “The ZeNix trial addresses a key concern that providers and patients have had regarding the safety and tolerability of taking 6 months of linezolid at 1200 mg/d as part of the BPaL regimen.

“The findings that doses lower and durations shorter than the current 1,200 mg linezolid daily for 6 months will significantly expand the usability of the BPaL regimen worldwide.”

The inclusion of patients with HIV was essential in the trial, he noted.

“There are drug-drug interactions to be considered, among other factors that impact drug exposure,” Dr. Nahid said.

“Inclusion of patients living with HIV in this study means that any modifications to the BPaL regimen considered by the WHO [World Health Organization] and other policy decision makers will include data from this key population,” he said. “Of course, more data are needed on safety, tolerability, and efficacy on BPaL in general, and there are international cohorts and demonstration projects underway that will enhance our understanding of the regimen in HIV and in other special populations.”

The authors, Dr. Streeck, and Dr. Nahid have disclosed no relevant financial relationships.

Habitual coffee drinking was not associated with a heightened risk of cardiac arrhythmias in a study of more than 300,000 people.

In fact, an adjusted analysis found that “each additional cup of coffee intake was associated with a 3% lower risk of incident arrhythmia,” Eun-jeong Kim, MD, of the division of cardiology at the University of California, San Francisco, and colleagues reported in JAMA Internal Medicine.

In addition, genetic differences that affect caffeine metabolism did not significantly influence the odds of arrhythmias, the researchers found.

Still, these findings should not necessarily encourage people to start drinking coffee if they don’t already, or to guzzle additional cups with abandon, they said.

American Heart Association

“We certainly don’t want to say drink coffee and it will reduce your risk of arrhythmias,” study author Gregory M. Marcus, MD, MAS, associate chief of cardiology for research at UCSF Health, said in an interview. “But rather, we think the main point is that a blanket prohibition against coffee or caffeine to reduce the risk of arrhythmias among patients who have a diagnosis of arrhythmias is likely unwarranted. And given some evidence that coffee consumption may actually have other benefits regarding diabetes, mood, and perhaps overall mortality, it may be problematic to admonish patients to avoid coffee or caffeine when it is not really warranted.”
 

Methods and results

The conventional wisdom that caffeine increases arrhythmic risk has not been well substantiated. To further examine whether moderate, habitual coffee drinking relates to arrhythmia risk, and whether certain genetic variants influence the association, Dr. Kim and colleagues analyzed data from the UK Biobank. They focused on longitudinal data collected between 2006 and 2018 from 386,258 people who did not have a prior diagnosis of arrhythmia.

Participants had an average age of 56 years, and about 52% were female. They provided information about their coffee consumption, and the researchers grouped the participants into eight categories based on their daily coffee intake: 0, less than 1, 1, 2, 3, 4, 5, and 6 or more cups per day.

Over an average follow-up of 4.5 years, 16,979 participants developed an incident arrhythmia. After adjusting for demographic characteristics, comorbid conditions, and lifestyle habits, the decreased risk with each cup of coffee was similar for atrial fibrillation or flutter (hazard ratio, 0.97) and supraventricular tachycardia (HR, 0.96).

Taking into account genetic variations that relate to caffeine metabolism did not modify the findings. Mendelian randomization analyses that used a polygenic score of inherited caffeine metabolism patterns “failed to provide evidence that caffeine consumption leads to a greater risk of arrhythmias,” the researchers said.

Professional society guidelines have suggested staying away from caffeinated products to reduce the risk of arrhythmia, but this guidance has “relied on assumed mechanisms and a small observational study from 1980,” the authors wrote. Subsequent research has indicated that coffee’s reputation of increasing the risk of arrhythmia may be undeserved.

“The investigators should be commended on performing a high-quality observational study to try to further understand the association between coffee consumption and arrhythmias, or the lack of one,” commented Zachary D. Goldberger, MD, MS, with the division of cardiovascular medicine at the University of Wisconsin–Madison, who was not involved in the study. “This is not a randomized, controlled trial, and coffee consumption was self-reported, but the methods employed are rigorous, despite these and other important limitations. However, we need to be extremely cautious in how we interpret these findings, and not use these data as a prescription for more coffee. It’s important to recognize that this study is not telling us to drink more coffee, or start drinking coffee, to protect against developing arrhythmias. However, it should offer more reassurance that moderate coffee consumption is not necessarily harmful, and will not always lead to arrhythmias. This is important, given the widespread notion that coffee is universally proarrhythmic.”
 

A call for personalized guidance

“As the investigators note, there are definitely biologically plausible reasons how coffee and caffeine may not cause arrhythmias, and may be possibly protective in some, despite being a stimulant,” Dr. Goldberger said. “However, if your patient is reporting palpitations or symptoms of an arrhythmia, and feels they be related to coffee or caffeine, we should not use this study to tell them that coffee may not be the culprit. We need to listen to our patients, and the decision to reduce coffee consumption to reduce these symptoms needs to be personalized.”

The effect size was small, and only about 4% of the participants developed an arrhythmia, Dr. Goldberger and Rodney A. Hayward, MD, wrote in an invited commentary on the study in JAMA Internal Medicine. Dr. Hayward is a professor of public health and internal medicine at the University of Michigan, Ann Arbor, and a senior investigator at the Ann Arbor Veterans Affairs Center for Clinical Management Research.

“Unfortunately, coffee consumption was self-reported at a single time point. Not only can this lead to recall bias, but subsequent and substantial changes in coffee consumption are also possible, including reductions due to new signs or symptoms,” they said.
 

No evidence that coffee ups risk for developing arrhythmias

Another recent study suggests that people may alter their coffee consumption depending on their baseline cardiovascular health, according to the commentary.

Overall, the results “strengthen the evidence that caffeine is not proarrhythmic, but they should not be taken as proving that coffee is an antiarrhythmic—this distinction is of paramount importance,” Dr. Goldberger and Dr. Hayward wrote. “Health care professionals can reassure patients that there is no evidence that drinking coffee increases the risk for developing arrhythmias. This is particularly important for the many patients with benign palpitations who are devastated when they think, or are told, that they have to stop drinking coffee. Given current evidence, this is entirely a patient-preference decision, not a medical one.”

Dr. Marcus, a cardiac electrophysiologist, sees patients with arrhythmias all the time. They tend to “come in fairly convinced that caffeine is to be avoided when they have arrhythmias,” he said. “Often, they been told by their primary care physician or their general cardiologist to avoid caffeine because they have an arrhythmia.

“What I suggest to my patients is that they feel free to go ahead and experiment and try coffee,” Dr. Marcus said.

Still, Dr. Marcus suspects that there are some individuals in whom caffeine is a trigger for the arrhythmia. But evidence indicates these cases likely are rare, and avoiding caffeine need not apply to the general population, particularly “given the potential health benefits of benefits of coffee and also, frankly, just the enhanced quality of life that people can enjoy drinking a good cup of coffee.”

The research was conducted using the UK Biobank resource, which was established by the Wellcome Trust, the Medical Research Council, the U.K. Department of Health, and the Scottish government. The UK Biobank has received funding from other agencies and foundations as well. Dr. Marcus disclosed grants from Baylis, Medtronic, and Eight Sleep outside the submitted work. In addition, he reported consulting for Johnson & Johnson and InCarda, and holding equity in InCarda. A coauthor received salary support from the National Institutes of Health during the study. Dr. Goldberger and Dr. Hayward disclosed no conflicts of interest.

Habitual coffee drinking was not associated with a heightened risk of cardiac arrhythmias in a study of more than 300,000 people.

In fact, an adjusted analysis found that “each additional cup of coffee intake was associated with a 3% lower risk of incident arrhythmia,” Eun-jeong Kim, MD, of the division of cardiology at the University of California, San Francisco, and colleagues reported in JAMA Internal Medicine.

In addition, genetic differences that affect caffeine metabolism did not significantly influence the odds of arrhythmias, the researchers found.

Still, these findings should not necessarily encourage people to start drinking coffee if they don’t already, or to guzzle additional cups with abandon, they said.

American Heart Association

“We certainly don’t want to say drink coffee and it will reduce your risk of arrhythmias,” study author Gregory M. Marcus, MD, MAS, associate chief of cardiology for research at UCSF Health, said in an interview. “But rather, we think the main point is that a blanket prohibition against coffee or caffeine to reduce the risk of arrhythmias among patients who have a diagnosis of arrhythmias is likely unwarranted. And given some evidence that coffee consumption may actually have other benefits regarding diabetes, mood, and perhaps overall mortality, it may be problematic to admonish patients to avoid coffee or caffeine when it is not really warranted.”
 

Methods and results

The conventional wisdom that caffeine increases arrhythmic risk has not been well substantiated. To further examine whether moderate, habitual coffee drinking relates to arrhythmia risk, and whether certain genetic variants influence the association, Dr. Kim and colleagues analyzed data from the UK Biobank. They focused on longitudinal data collected between 2006 and 2018 from 386,258 people who did not have a prior diagnosis of arrhythmia.

Participants had an average age of 56 years, and about 52% were female. They provided information about their coffee consumption, and the researchers grouped the participants into eight categories based on their daily coffee intake: 0, less than 1, 1, 2, 3, 4, 5, and 6 or more cups per day.

Over an average follow-up of 4.5 years, 16,979 participants developed an incident arrhythmia. After adjusting for demographic characteristics, comorbid conditions, and lifestyle habits, the decreased risk with each cup of coffee was similar for atrial fibrillation or flutter (hazard ratio, 0.97) and supraventricular tachycardia (HR, 0.96).

Taking into account genetic variations that relate to caffeine metabolism did not modify the findings. Mendelian randomization analyses that used a polygenic score of inherited caffeine metabolism patterns “failed to provide evidence that caffeine consumption leads to a greater risk of arrhythmias,” the researchers said.

Professional society guidelines have suggested staying away from caffeinated products to reduce the risk of arrhythmia, but this guidance has “relied on assumed mechanisms and a small observational study from 1980,” the authors wrote. Subsequent research has indicated that coffee’s reputation of increasing the risk of arrhythmia may be undeserved.

“The investigators should be commended on performing a high-quality observational study to try to further understand the association between coffee consumption and arrhythmias, or the lack of one,” commented Zachary D. Goldberger, MD, MS, with the division of cardiovascular medicine at the University of Wisconsin–Madison, who was not involved in the study. “This is not a randomized, controlled trial, and coffee consumption was self-reported, but the methods employed are rigorous, despite these and other important limitations. However, we need to be extremely cautious in how we interpret these findings, and not use these data as a prescription for more coffee. It’s important to recognize that this study is not telling us to drink more coffee, or start drinking coffee, to protect against developing arrhythmias. However, it should offer more reassurance that moderate coffee consumption is not necessarily harmful, and will not always lead to arrhythmias. This is important, given the widespread notion that coffee is universally proarrhythmic.”
 

A call for personalized guidance

“As the investigators note, there are definitely biologically plausible reasons how coffee and caffeine may not cause arrhythmias, and may be possibly protective in some, despite being a stimulant,” Dr. Goldberger said. “However, if your patient is reporting palpitations or symptoms of an arrhythmia, and feels they be related to coffee or caffeine, we should not use this study to tell them that coffee may not be the culprit. We need to listen to our patients, and the decision to reduce coffee consumption to reduce these symptoms needs to be personalized.”

The effect size was small, and only about 4% of the participants developed an arrhythmia, Dr. Goldberger and Rodney A. Hayward, MD, wrote in an invited commentary on the study in JAMA Internal Medicine. Dr. Hayward is a professor of public health and internal medicine at the University of Michigan, Ann Arbor, and a senior investigator at the Ann Arbor Veterans Affairs Center for Clinical Management Research.

“Unfortunately, coffee consumption was self-reported at a single time point. Not only can this lead to recall bias, but subsequent and substantial changes in coffee consumption are also possible, including reductions due to new signs or symptoms,” they said.
 

No evidence that coffee ups risk for developing arrhythmias

Another recent study suggests that people may alter their coffee consumption depending on their baseline cardiovascular health, according to the commentary.

Overall, the results “strengthen the evidence that caffeine is not proarrhythmic, but they should not be taken as proving that coffee is an antiarrhythmic—this distinction is of paramount importance,” Dr. Goldberger and Dr. Hayward wrote. “Health care professionals can reassure patients that there is no evidence that drinking coffee increases the risk for developing arrhythmias. This is particularly important for the many patients with benign palpitations who are devastated when they think, or are told, that they have to stop drinking coffee. Given current evidence, this is entirely a patient-preference decision, not a medical one.”

Dr. Marcus, a cardiac electrophysiologist, sees patients with arrhythmias all the time. They tend to “come in fairly convinced that caffeine is to be avoided when they have arrhythmias,” he said. “Often, they been told by their primary care physician or their general cardiologist to avoid caffeine because they have an arrhythmia.

“What I suggest to my patients is that they feel free to go ahead and experiment and try coffee,” Dr. Marcus said.

Still, Dr. Marcus suspects that there are some individuals in whom caffeine is a trigger for the arrhythmia. But evidence indicates these cases likely are rare, and avoiding caffeine need not apply to the general population, particularly “given the potential health benefits of benefits of coffee and also, frankly, just the enhanced quality of life that people can enjoy drinking a good cup of coffee.”

The research was conducted using the UK Biobank resource, which was established by the Wellcome Trust, the Medical Research Council, the U.K. Department of Health, and the Scottish government. The UK Biobank has received funding from other agencies and foundations as well. Dr. Marcus disclosed grants from Baylis, Medtronic, and Eight Sleep outside the submitted work. In addition, he reported consulting for Johnson & Johnson and InCarda, and holding equity in InCarda. A coauthor received salary support from the National Institutes of Health during the study. Dr. Goldberger and Dr. Hayward disclosed no conflicts of interest.

ANSWER

The correct answer is all of the above (choice “f”).

DISCUSSION

The most likely diagnostic explanation for this patient’s presentation is erythema annulare centrifugum (EAC; choice “c”). However, this diagnosis is often difficult to establish, in part because of the broad differential and also because the very existence of EAC is far from well established.

The overwhelming consensus is that EAC represents a hypersensitivity reaction to an unknown antigen. It can be triggered by a wide variety of micro-organisms, stress, or even pregnancy.

In this case, there was no clinical or historical reason to suspect an underlying cancer, Lyme disease, or lupus, nor did the biopsy results suggest any of these.

The key takeaway here is to urge providers to avoid jumping onto a diagnostic bandwagon before considering a wider differential. Indeed, size matters when it relates to the length of one’s differential diagnosis list. If you don’t consider it, you can’t diagnose it.

TREATMENT

Fortunately, EAC nearly always resolves, with or without treatment. This patient received reassurance as such but was scheduled to return for a check of his lesions in 2 months. At that point, they had resolved.

Consumers should stop using certain brands of spray-on sunscreen products made by Johnson & Johnson. The company has issued a voluntary recall after finding low levels of benzene, a known cancer-causing agent, in some samples.

Benzene is not an ingredient of sunscreen, and should not be present in these products. The levels detected were low and would not be expected to have an adverse effect on health, but the company says it is recalling the products anyway “out of an abundance of caution.”

The sunscreen products that have been recalled are:

• NEUTROGENA® Beach Defense® aerosol sunscreen.
• NEUTROGENA® Cool Dry Sport aerosol sunscreen.
• NEUTROGENA® Invisible Daily™ defense aerosol sunscreen.
• NEUTROGENA® Ultra Sheer® aerosol sunscreen.
• AVEENO® Protect + Refresh aerosol sunscreen.

These products were distributed nationwide through a variety of retail stores. Consumers should stop using these products and throw them away, the company said.

At the same time, it emphasized the importance of using alternative sunscreen products to protect the skin from excessive sun exposure, which can lead to skin cancer including melanoma.

Johnson & Johnson has launched an investigation into how benzene got into these products.

One of the company’s other spray sunscreen products, Neutrogena Wet Skin, was not included in the recall.

Recently, benzene was found in 78 widely-used sunscreen products in tests conducted by the online pharmacy and laboratory Valisure. Most of the products were aerosol sprays, and the company called on the Food and Drug Administration to recall them all.

That petition suggested that the finding of benzene was the result of contamination somewhere in the manufacturing process.

“This isn’t a sunscreen issue, it’s a manufacturing issue,” said Adam Friedman, MD, professor and chief of dermatology at George Washington University. “We don’t want those things to be blurred.”

There is a risk that people take away the wrong message from these findings.

“People already have ambivalence about sunscreen, and this is just going to make that worse,” Dr. Friedman said in an interview.

He pointed out that benzene is present in car exhaust, second-hand smoke, and elsewhere. Inhalation exposure has been the primary focus of toxicology investigations, as has exposure from things such as contaminated drinking water – not via topical application. “We don’t know how effectively [benzene] gets through the skin, if it gets absorbed systemically, and how that then behaves downstream,” he noted.

On the other hand, ultraviolet radiation is a well-established carcinogen. Avoiding an effective preventive measure such as sunscreen could prove more harmful than exposure to trace amounts of benzene, he said.

Dupilumab (Dupixent, Sanofi and Regeneron) significantly reduced exacerbations compared with placebo in children ages 6-11 years who had moderate-to-severe asthma in a phase 3 trial.

A fully human monoclonal antibody, dupilumab also improved lung function versus placebo by week 12, an improvement that lasted the length of the 52-week trial.

Dupilumab previously had been shown to be safe and effective in adolescents and adults with moderate-to-severe asthma, patients 6 years and older with moderate-to-severe atopic dermatitis, and adults with chronic rhinosinusitis with nasal polyposis, but its safety and effectiveness for moderate-to-severe asthma in the 6-11 years age group was not known.

Results from the randomized, double-blind VOYAGE study conducted across several countries were presented Saturday, July 10, at the European Academy of Allergy and Clinical Immunology (EAACI) Hybrid Congress 2021.

Leonard B. Bacharier, MD, professor of pediatrics, allergy/immunology/pulmonary medicine at Vanderbilt University Medical Center in Nashville, Tennessee, presented the results from the trial, which was funded by Sanofi/Regeneron.

Researchers enrolled 408 children ages 6-11 years with uncontrolled moderate-to-severe asthma. Children on high-dose inhaled corticosteroids (ICS) alone or medium-to-high–dose ICS with a second controller were randomly assigned either to add-on subcutaneous dupilumab 100 mg or 200 mg, based on body weight at study start, or to placebo every 2 weeks for 52 weeks.

Analyses were done in two populations: 350 patients with markers of type 2 inflammation (baseline blood eosinophils ≥150 cells/μl or fractional exhaled nitric oxide [FeNO] ≥20 ppb) and 259 patients with baseline blood eosinophils ≥300 cells/µl.

“The primary endpoint was the annualized rate of severe asthma exacerbations,” Dr. Bacharier said. “The key secondary endpoint was change in percent predicted prebronchodilator FEV1 [forced expiratory volume at 1 second] from baseline to week 12.”

At week 12, the annualized severe asthma exacerbation rate was reduced by 59% (P < .0001) in children with blood eosinophils ≥300 cells/µL and results were similar in those with the type 2 inflammatory phenotype compared with placebo.

Results also indicate a favorable safety profile for dupilumab.

James M. Tracy, DO, an expert with the American College of Allergy, Asthma, and Immunology, told this news organization that adding the dupilumab option for children in the 6-11 age group is “huge.”

Dr. Tracy, who was not involved with the study, said although omalizumab (Xolair, Genentech) is also available for these children, dupilumab stands out because of the range of comorbidities it can treat.

“[Children] don’t have the same rhinosinusitis and polyposis that adults would have, but a lot of them have eczema, and this drug with multiple prongs is incredibly useful and addresses a broad array of allergic conditions,” Dr. Tracy said.

More than 90% of children in the study had at least one concurrent type 2 inflammatory condition, including atopic dermatitis and eosinophilic esophagitis. Dupilumab blocks the shared receptor for interleukin (IL)-4/IL-13, which are key drivers of type 2 inflammation in multiple diseases.

Dr. Tracy said that while dupilumab is not the only drug available to treat children 6-11 years with moderate-to-severe asthma, it is “a significant and unique addition to the armamentarium of the individual practitioner taking care of these very severe asthmatics in the 6-11 age group.”

Dupilumab also led to rapid and sustained improvement in lung function. At 12 weeks, children assigned dupilumab improved their lung function as measured by FEV1 by 5.21% (P = .0009), and that continued through the 52-week study period.

“What we know is the [improved lung function] effect is sustained. What we don’t know is how long you have to keep on the drug for a more permanent effect, which is an issue for all these biologics,” Tracy said.

Dr. Bacharier reported speaker fees and research support from Sanofi/Regeneron. Dr. Tracy has disclosed no relevant financial relationships.

A new draft consensus statement from the American Diabetes Association and the European Association for the Study of Diabetes (EASD) addresses diagnosis and management of type 1 diabetes in adults.  

The impetus for the document comes from the “highly influential” EASD-ADA consensus report on the management of type 2 diabetes, which led to the realization that a comparable document was needed for adults with type 1 diabetes, said writing panel cochair Anne L. Peters, MD, professor of clinical medicine at the University of Southern California, Los Angeles.

“In recent years, there have been rapid advances in the treatment of type 1 diabetes together with a growing recognition of the psychosocial burden of living with [it],” Dr. Peters said.

She noted that although there is already some guidance available for the management of type 1 diabetes in adults, “this gets admixed into broader guidelines, and many of those are mostly derived from data in people with type 2 diabetes.”  

The new draft document was coauthored by 14 content experts in type 1 diabetes, with equal numbers from the United States and Europe.
 

We want to be helpful to clinicians

Topics covered include diagnosis of type 1 diabetes, goals of therapy and glycemic targets, schedule of care, diabetes self-management education and additional behavioral considerations, glucose monitoring, insulin therapy, hypoglycemia, psychosocial care, diabetic ketoacidosis, pancreas and islet cell transplantation, adjunctive therapies, special populations (including pregnant women, older adults, and inpatient management), and emergent/future perspectives, including beta-cell replacement and immunotherapy.

At the end of the document are tables of glycemic targets for adults with type 1 diabetes, schedule of care, nonglycemic factors that alter A1c levels, standardized continuous glucose meter (CGM) metrics for clinical care, examples of subcutaneous insulin regimens, and the various properties of approved and nonapproved adjunctive therapies for type 1 diabetes, including metformin, pramlintide, GLP-1 agonists, and SGLT2 inhibitors.  

Several colorful flowcharts are also provided, including algorithms for diagnosing and managing type 1 diabetes in adults.

Document coauthor M. Sue Kirkman, MD, of the Diabetes Care Center’s Clinical Trials Unit at the University of North Carolina, Chapel Hill, told this news organization: “We want it to be helpful to clinicians who are diagnosing type 1 diabetes in adults or caring for adults with type 1 diabetes, whether diagnosed in childhood or adulthood.”

The authors presented an overview of the document in a symposium on June 28 at the virtual ADA scientific sessions. The final version will be presented Oct. 1 at the EASD 2021 annual meeting.

The draft document and video of the ADA meeting presentation are both available on the ADA website.
 

New algorithm to reduce misdiagnosis of type 1 diabetes in adults

Misdiagnosis of adult-onset type 1 diabetes is common, occurring in up to 40% of those who develop the condition after age 30 years, said J. Hans de Vries, MD, PhD, medical director, Profil Institute for Metabolic Research, Neuss, Germany.

There are multiple reasons for this, including the fact that obesity and type 2 diabetes are becoming more prevalent at younger ages, C-peptide levels may still be relatively high at the time of clinical type 1 diabetes onset, and islet autoantibodies don’t have 100% positive predictive value.

“No single feature confirms type 1 diabetes in isolation,” Dr. de Vries noted.

The document provides a detailed diagnostic algorithm specifically for adults in whom type 1 diabetes is suspected, starting with autoantibody measurement. If the diagnosis isn’t confirmed that way, the algorithm advises investigating for monogenic diabetes, including use of a maturity-onset diabetes of the young (MODY) calculator and subsequent C-peptide measurement.

Measurement of C-peptide is also recommended if the diabetes type is still uncertain more than 3 years after diabetes onset in those treated with insulin, because by that point it is likely to be <200 pmol/L in people with type 1 diabetes.  
 

Clear statements on diabetes technology, preferred insulins

The draft document clearly states that physiologic insulin replacement using a pump or multiple daily injections, CGM, and analog rather than human insulin are standards of care for adults with type 1 diabetes. Use of hybrid closed-loop insulin delivery systems is advised when available, as they offer the “greatest benefits.”

However, the document also notes that in cases of cost barriers, subcutaneous regimens of human regular and NPH insulin may be used. It cautions, though, that these may result in higher glucose variability, higher risk of hypoglycemia, and less lifestyle flexibility.

Dr. Kirkman told this news organization: “Using human insulins such as NPH and Regular in type 1 diabetes is definitely not preferred, but sometimes due to people’s inability to afford analogs we have to use them. People need to know how to use them safely.”

As for the do-it-yourself insulin delivery systems, which many with type 1 diabetes now use with open-source software algorithms that reverse-engineer older pumps, the document advises that health care providers shouldn’t actively recommend them as they’re not approved by regulatory authorities, but should also “respect the individual’s right to make informed choices and continue to offer support,” Dr. Kirkman said when presenting the insulin therapy section.
 

Psychosocial aspects of type 1 diabetes ‘underappreciated’

Special emphasis is placed on psychosocial support, which may be overlooked in adults, Dr. Kirkman noted.

“Clinicians probably underappreciate what people with type 1 diabetes go through on a daily basis. A lot of the evidence out there regarding psychosocial issues is in children and families of children with type 1 diabetes, or in adults with type 2 diabetes ... Maximizing quality of life needs to be at the forefront of care, not just focusing on glycemic goals.”

Indeed, between 20% and 40% of people with type 1 diabetes experience diabetes-related emotional distress – including 15% with depression – particularly at the time of diagnosis and when complications develop, noted Frank J. Snoek, PhD, professor of medical psychology at Amsterdam University Medical Center, the Netherlands.

To address this, the draft advises that “self-management difficulties, psychological, and social problems” be screened periodically and monitored using validated screening tools.

“Health care providers should be proficient at asking questions about and discussing emotional health, psychological needs, and social challenges as part of the consultation,” Dr. Snoek said.

Dr. Peters disclosed ties with Abbott Diabetes Care, AstraZeneca, Lilly, Medscape, Novo Nordisk, Vertex, and Zealand, Omada, and Teladoc. Dr. Kirkman has received research support from Novo Nordisk and Bayer. Dr. de Vries disclosed ties with Adocia, Novo Nordisk, Zealand, Eli Lilly, and Afon Technology. Dr. Snoek reported ties with Roche Diabetes, Novo Nordisk, Sanofi, and Eli Lilly.

A new draft consensus statement from the American Diabetes Association and the European Association for the Study of Diabetes (EASD) addresses diagnosis and management of type 1 diabetes in adults.  

The impetus for the document comes from the “highly influential” EASD-ADA consensus report on the management of type 2 diabetes, which led to the realization that a comparable document was needed for adults with type 1 diabetes, said writing panel cochair Anne L. Peters, MD, professor of clinical medicine at the University of Southern California, Los Angeles.

“In recent years, there have been rapid advances in the treatment of type 1 diabetes together with a growing recognition of the psychosocial burden of living with [it],” Dr. Peters said.

She noted that although there is already some guidance available for the management of type 1 diabetes in adults, “this gets admixed into broader guidelines, and many of those are mostly derived from data in people with type 2 diabetes.”  

The new draft document was coauthored by 14 content experts in type 1 diabetes, with equal numbers from the United States and Europe.
 

We want to be helpful to clinicians

Topics covered include diagnosis of type 1 diabetes, goals of therapy and glycemic targets, schedule of care, diabetes self-management education and additional behavioral considerations, glucose monitoring, insulin therapy, hypoglycemia, psychosocial care, diabetic ketoacidosis, pancreas and islet cell transplantation, adjunctive therapies, special populations (including pregnant women, older adults, and inpatient management), and emergent/future perspectives, including beta-cell replacement and immunotherapy.

At the end of the document are tables of glycemic targets for adults with type 1 diabetes, schedule of care, nonglycemic factors that alter A1c levels, standardized continuous glucose meter (CGM) metrics for clinical care, examples of subcutaneous insulin regimens, and the various properties of approved and nonapproved adjunctive therapies for type 1 diabetes, including metformin, pramlintide, GLP-1 agonists, and SGLT2 inhibitors.  

Several colorful flowcharts are also provided, including algorithms for diagnosing and managing type 1 diabetes in adults.

Document coauthor M. Sue Kirkman, MD, of the Diabetes Care Center’s Clinical Trials Unit at the University of North Carolina, Chapel Hill, told this news organization: “We want it to be helpful to clinicians who are diagnosing type 1 diabetes in adults or caring for adults with type 1 diabetes, whether diagnosed in childhood or adulthood.”

The authors presented an overview of the document in a symposium on June 28 at the virtual ADA scientific sessions. The final version will be presented Oct. 1 at the EASD 2021 annual meeting.

The draft document and video of the ADA meeting presentation are both available on the ADA website.
 

New algorithm to reduce misdiagnosis of type 1 diabetes in adults

Misdiagnosis of adult-onset type 1 diabetes is common, occurring in up to 40% of those who develop the condition after age 30 years, said J. Hans de Vries, MD, PhD, medical director, Profil Institute for Metabolic Research, Neuss, Germany.

There are multiple reasons for this, including the fact that obesity and type 2 diabetes are becoming more prevalent at younger ages, C-peptide levels may still be relatively high at the time of clinical type 1 diabetes onset, and islet autoantibodies don’t have 100% positive predictive value.

“No single feature confirms type 1 diabetes in isolation,” Dr. de Vries noted.

The document provides a detailed diagnostic algorithm specifically for adults in whom type 1 diabetes is suspected, starting with autoantibody measurement. If the diagnosis isn’t confirmed that way, the algorithm advises investigating for monogenic diabetes, including use of a maturity-onset diabetes of the young (MODY) calculator and subsequent C-peptide measurement.

Measurement of C-peptide is also recommended if the diabetes type is still uncertain more than 3 years after diabetes onset in those treated with insulin, because by that point it is likely to be <200 pmol/L in people with type 1 diabetes.

Congenital onychodysplasia of the index finger (COIF), or Iso-Kikuchi syndrome, is a rare disorder characterized by malformation of one or both nails of the index fingers. The various anomalies described are anonychia, micronychia, polyonychia, malalignment, or hemi-onychogryphosis. It may be associated with abnormalities of the underlying phalangeal bone, the most masked being bifurcation of the terminal phalange.¹ Initially thought to be nonhereditary and nonfamilial,² it is now known that COIF can be inherited in an autosomal-dominant fashion.³ Millman and Strier³ described a family of 9 patients with COIF. It rarely is described outside of Japan. Padmavathy et al⁴ described a case in an Indian patient with COIF that was associated with the absence of a ring finger in addition to anomalies of the metacarpal bones.

Congenital onychodysplasia of the index finger has a broad spectrum regarding its etiology and clinical features.⁵ The pathogenesis of COIF still is poorly understood. Deficient circulation in digital arteries is thought to be a putative mechanism for developing a deformed nail. The nail is affected on the radial side of the index finger, likely because of the smaller caliber of the artery on that side.⁵ Hereditary as well as nonhereditary sporadic cases have been reported. In addition to the various fingernail anomalies, skeletal abnormalities also have been reported. Baran and Stroud⁶ have reported deformed lunulae as a manifestation of COIF.

The Diagnosis: Congenital Onychodysplasia of the Index Finger

The differential diagnosis of COIF includes hidrotic ectodermal dysplasia, nail-patella syndrome, Poland syndrome, and DOOR syndrome. Hidrotic ectodermal dysplasia exhibits onychodystrophy, generalized hypotrichosis, palmoplantar keratoderma, and dental anomalies.⁷ Nail-patella syndrome presents with hypoplasia of the fingernails and toenails, triangular nail lunulae, absent or hypoplastic patellae, and elbow and iliac horn dysplasia. Poland syndrome is distinguished from COIF by the congenital absence of the pectoralis major muscle on the ipsilateral side of the involved digits. The DOOR syndrome tetrad is comprised of deafness, onychodystrophy, osteodystrophy, and mental retardation.⁸ Unlike these conditions, COIF does not involve systems other than the nails and phalanges.

Treatment of this condition is mainly conservative, as patients typically do not have symptoms.⁹ Surgical interventions can be considered for cosmetic concerns. Knowledge of this congenital entity and its clinical findings is essential to prevent unnecessary procedures and workup.

In April, 92 people gathered in Texas for a wedding. To lower the chances of COVID-19 infection, the festivities were held outside under a large, open-air tent. All 92 guests were required to be fully vaccinated.

Despite those precautions, six people tested positive for the coronavirus and one of them died, Forbes magazine reported, citing a preprint published in medRxiv.

Researchers from Baylor College of Medicine said viral sequencing suggests “the strain containing the Delta variant was transmitted to wedding guests from two patients traveling from India. With no history of vaccine failure in these patients, our observations suggest these are true cases of vaccine breakthrough, mediated by the Delta variant.”

Three females and three males aged 53-69 tested positive for COVID-19. Three were overweight, but none had significant comorbidities or a history of failed vaccination.

The first people to get sick were a man and woman who traveled from India, Forbes reported. The man had no health problems, but the woman had diabetes. Both had gotten two doses of the Covaxin BBV152 vaccine before leaving India.

They tested positive for COVID-19 4 days after the wedding, and the man became so ill he was hospitalized. Six days after the wedding, he died, according to Forbes.

Two people who’d gotten the Pfizer/BioNTech vaccine and two people who received the Moderna vaccine interacted with the first two people, and they also tested positive. One of them, a man in his 60s, had to be hospitalized.

The researchers said their findings suggest the Delta variant “may possess immune evasion” in patients that received the Pfizer, Moderna, or Covaxin vaccines.

Forbes summed it up this way: “While the available COVID-19 vaccines can offer good protection against COVID-19, the protection is not perfect. As long as the pandemic is continuing, it is better to maintain multiple layers of COVID-19 precautions when you can.”
