Clinician Reviews

A class of drugs long used to treat HIV and hepatitis B viral infections appears to prevent the development of diabetes in a substantial proportion of patients who take these agents, an analysis of multiple databases has shown.

“Nucleoside reverse transcriptase inhibitors [NRTIs], drugs approved to treat HIV-1 and hepatitis B infections, also block inflammasome activation,” Jayakrishna Ambati, MD, University of Virginia, Charlottesville, and colleagues wrote in Nature Communications.

“[We showed that] the adjusted risk of incident diabetes is 33% lower in patients with NRTI exposure. ... These data suggest the possibility of repurposing an approved class of drugs for prevention of diabetes,” they wrote.

The researchers made a small chemical modification to NRTIs that led to their developing a new class of drugs, which they have termed “kamuvudines.” Kamuvudines are nontoxic derivatives of NRTIs, Dr. Ambati said in an interview.

“People take NRTIs because they need to live with HIV, but giving them to the general population is not a great idea because of the toxicities associated with long-term NRTI use. So our focus is not to go forward specifically with NRTIs but rather with these new molecules that are far less toxic, and that is how we envision a clinical trial going forward,” Dr. Ambati noted.
 

Researchers screened five databases of >100,000 patients

Dr. Ambati and colleagues analyzed information from five databases in which patients who had been exposed to an NRTI but who had not previously been diagnosed with type 2 diabetes were assessed for the subsequent development of diabetes over varying time intervals. In one, the Veterans Health Administration database – from the largest integrated health care system in the United States – the analysis spanned a period of 17 years.

Of 79,744 patients with a confirmed diagnosis of HIV or hepatitis B in the Veterans Health Administration database, the risk for type 2 diabetes was reduced by 34% among NRTI users, compared with nonusers after adjusting for potential confounders (P < .0001).

The reduction in diabetes risk was similar among HIV-positive and hepatitis B–positive patients.

These results were reaffirmed by further analyses of four other databases, the investigators reported. One of these, the employer-based health insurance Truven database, had data on 23,634 patients who had been diagnosed with HIV or hepatitis B. After adjusting for potential confounders, NRTI users had a 39% lower risk of developing type 2 diabetes, compared with nonusers (P < .0001).

The risk of developing type 2 diabetes was somewhat lower among NRTI users in the Pearl Diver database, which includes predominantly private health insurance claims. Of 16,045 patients diagnosed with HIV or hepatitis B included in this database, the risk for type 2 diabetes was 26% lower among NRTI users, compared with nonusers (P = .004).

A similar magnitude of risk reduction was seen in the analysis of the Clinformatics dataset. Among 6,341 users of NRTIs, the risk for type 2 diabetes was 27% lower than it was for nonusers (P = .009).

The least reduction in diabetes risk was in the Medicare database, in which only 3,097 patients had been diagnosed with either HIV or hepatitis B. Among these patients, the risk for diabetes was 17% lower among NRTI users than it was for nonusers (P = .137).
 

One-third reduction across multiple databases enhances confidence

“Collectively, among 128,861 patients with HIV-1 or hepatitis B, users of NRTIs had a 33% reduced hazard of developing type 2 diabetes,” Dr. Ambati and colleagues emphasize.

“The fact that the protective effect against the development of diabetes was replicated in multiple databases in studies from multiple institutions enhances confidence in the results,” Dr. Ambati noted in a statement from the University of Virginia.

Dr. Ambati and colleagues also showed that the NRTI lamivudine restores insulin sensitivity in human cells from type 2 diabetes patients.

That drug prevented induction of insulin resistance in human cells from people who did not have diabetes. It also prevented inflammasome activation in mice fed a high-fat diet.

“These investigations of human cell, mouse and population database systems collectively suggest a potential beneficial effect of NRTIs in forestalling diabetes onset,” they stressed.
 

Trial assessing kamuvudines slated to begin next year

In the interview, Dr. Ambati explained that inflammasomes are protein complexes that form a large superstructure within the cell. “When activated, they lead to the production of some very powerful inflammatory cytokines, including interleukin-1 beta and IL-18.”

Although there are many different types of inflammasomes, the one implicated in type 2 diabetes, as well as many other chronic diseases, including macular degeneration, is the NLRP3 inflammasome.

Activation of this molecule promotes insulin resistance, a key driver of type 2 diabetes, he explained.

Importantly, previous research showed that the way the NRTIs block this inflammasome has nothing to do with their anti-HIV activity.

After making a small chemical modification in the NRTIs, Dr. Ambati and colleagues were able to show that the resulting agents, which they have dubbed “kamuvudines,” are able to block inflammasome activation independently of their antiviral effects.

They hope that this modification will reduce the toxicities associated with the agents. This would be necessary if kamuvudines were to be more widely used in a noninfected, healthier population, Ambati stressed.

Dr. Ambati and his colleague, Paul Ashton, PhD, cofounder of Inflammasone Therapeutics, plan a clinical trial with one of these kamuvudines in macular degeneration, which they hope will begin early next year.

“We are trying to pick a disease where we can show efficacy fairly quickly in a small number of people,” Dr. Ashton explained in an interview. “We’re very enthusiastic about this as it looks really, really promising.”

A new, large study has confirmed that different types of hormone replacement therapy (HRT) are associated with an increased risk for breast cancer and has provided additional information on factors associated with that increased risk.

The study was published online on October 28 in The BMJ.

“The study confirms increased risk of breast cancer in patients taking HRT but shows that the magnitude of risk depends on a number of factors,” first author Yana Vinogradova, PhD, said in an interview. Dr. Vinogradova is a medical statistician at the University of Nottingham (England).

The study also suggests the risk may be lower than was estimated in a large meta-analysis of 24 trials that was published in 2019 in The Lancet. In that study, researchers suggested the risk for breast cancer with HRT was higher and persisted longer than had been thought.

This conclusion from the meta-analysis was widely reported in the lay press and led to the UK Medicine and Healthcare Products Regulatory Agency issuing a safety alert for HRT regarding breast cancer. Experts in the field questioned the alert and said it caused undue anxiety. The European Medicines Agency also issued a safety alert because of the study.

This new study was begun before publication of the meta-analysis. Although the results are broadly similar in suggesting increased risk for breast cancer with HRT use, findings from the new study suggest the risk is lower than had been estimated in the meta-analysis and that the risk diminishes more rapidly after stopping HRT than was suggested by the meta-analysis.

“The publicity surrounding publication of the meta-analysis highlighted unexpectedly high risks and led to a heightened level of concern in some quarters,” Dr. Vinogradova commented. “Our study, based on general population data, has not confirmed any such findings. In general, it showed lower levels of risk and clarified the variability of magnitude within them.”

Dr. Vinogradova said the discrepancy could be related to the fact that the studies were designed differently. The meta-analysis relied on results from 24 studies that were conducted around the world at different periods and included women of different ages and backgrounds. The studies in the meta-analysis used different methods, including questionnaires that relied on women’s memories and therefore could have been biased, she said.

In contrast, the new study analyzed EMR data collected prospectively by general practices in the United Kingdom. The data came from the QResearch and from the Clinical Practice Research Datalink (CPRD) databases, the two largest primary care databases in the United Kingdom, which were linked to hospital, mortality, and cancer registries.

Because this study used a “consistent design” and “consistent data sources,” these new results “are likely to be more accurate and reliable for assessing risks among HRT users,” Dr. Vinogradova commented.

This study used an observational design, so it cannot prove that HRT causes breast cancer. These results may better represent women in the general U.K. population, compared with the earlier meta-analysis, she added.

Commenting on the new study, Michael Jones, PhD, senior staff scientist in genetics and epidemiology at the Institute of Cancer Research, London, also emphasized that it was large and its data came from general practitioner medical records, “so the strong statistical associations are unlikely to be due to chance.

“The results of this study generally confirm what has been seen before and is well established – that the use of combined estrogen plus progestogen HRT is associated with increased risk of breast cancer, and this risk increases with duration of use. But reassuringly, after stopping HRT, the raised risk of breast cancer mostly returns to that seen in nonusers of HRT,” he said.

“It’s important to note that no one study should be considered in isolation,” he added. “Even though some risks were found to be slightly smaller than those reported in another meta-analysis of the worldwide epidemiological evidence recently published in 2019, women considering use of HRT should still follow advice given to them by their [general practitioners].”
 

Study details

In the study, researchers evaluated all types of HRT commonly prescribed in the United Kingdom over the past 20 years, including topical estrogen, vaginal pessaries, and creams. They grouped HRT use by recent (within the past 5 years) and past (5 or more years ago) and HRT duration as short term (less than 5 years) and long term (5 years or longer). Results were adjusted for a range of factors that could affect breast cancer risk, including lifestyle, smoking, alcohol consumption, other medical conditions, family history, and use of other prescribed drugs.

The analysis included 98,611 women aged 50-79 years who were first diagnosed with breast cancer between 1998 and 2019. These women were matched by age and general practice to 457,498 women who were not diagnosed with breast cancer over these years. HRT use was reported in 34% (33,703) of women with breast cancer and in 31% (134,391) of women without breast cancer.

Overall, the risk for breast cancer was increased with use of most HRT drugs (adjusted odds ratio, 1.21; 95% confidence, 1.19-1.23), compared with not using HRT drugs. The highest risk was tied to combined estrogen/progestogen HRT (adjusted OR, 1.26; 95% CI, 1.24-1.29). The lowest risk was tied to estrogen-only HRT (adjusted OR, 1.06; 95% CI, 1.03-1.10). Estrogen cream and vaginal estrogen were not associated with increased breast cancer risk.

In general, breast cancer risk was higher among recent HRT users and those receiving long-term therapy. HRT-associated breast cancer risk increased with age and declined after discontinuing treatment. Therapy of less than 1 year was not associated with increased breast cancer risk.

Women who had recently been receiving long-term combined estrogen/progestogen HRT had a 79% increased risk for breast cancer (adjusted OR, 1.79; 95% CI, 1.73-1.85), compared with never-users. Among recent long-term users of combined HRT, breast cancer risk was highest for norethisterone (adjusted OR, 1.88; 95% CI, 1.79-1.99) and lowest for dydrogesterone (adjusted OR, 1.24; 95% CI, 1.03-1.48). Women who had recently been receiving long-term estrogen-only HRT had a 15% increased risk for breast cancer compared to never-users (adjusted OR, 1.15; 95% CI, 1.09-1.21).

Among women who discontinued HRT 5 or more years ago, risk for breast cancer was no longer increased for long-term estrogen-only therapy and short-term estrogen/progestogen therapy. However, breast cancer risk remained elevated 5 years after discontinuing long-term estrogen/progestogen (adjusted OR, 1.16; 95% CI, 1.11-1.21).

HRT-associated risk for breast cancer increased with age across all durations of therapy.

Compared with never-use, recent long-term estrogen-only therapy was associated with zero extra breast cancer cases per 10,000 women-years among women aged 50-59 years and eight extra cases per 10,000 women-years among women aged 70-79.

Recent long-term estrogen/progestogen use was associated with 15 extra breast cancer cases among women aged 50-59 and 36 extra cases among women aged 70-79 per 10,000 women-years.

Past long-term estrogen/progestogen use was associated with zero extra breast cancer cases among women aged 50-59 and eight extra cases among women aged 70-79 per 10,000 women-years.

Summarizing, Dr. Vinogradova said the increased risk for breast cancer with HRT appears to be “relatively small, particularly for younger women and for any women who use HRT only for a restricted period.”

Decisions about whether to use HRT and which type to use should depend on symptom severity, patient factors, and suitability of other treatment options, she commented.

“Particularly for those women who our study has shown to be most at risk, these decisions should be made through discussions between the patient and her doctor,” she concluded. “We hope that the new and more detailed information provided by our study will facilitate such prescribing decisions.”

The study was partially funded by the School for Primary Care Research of the National Institute for Health Research, by Cancer Research UK, and by the Cancer Research UK Oxford Center. Dr. Vinogradova has disclosed no relevant financial relationships. Senior author Julia Hippisley-Cox is an unpaid director of QResearch and was a paid director of ClinRisk until 2019. The other authors have disclosed no relevant financial relationships.

“Particularly for those women who our study has shown to be most at risk, these decisions should be made through discussions between the patient and her doctor,” she concluded. “We hope that the new and more detailed information provided by our study will facilitate such prescribing decisions.”

The study was partially funded by the School for Primary Care Research of the National Institute for Health Research, by Cancer Research UK, and by the Cancer Research UK Oxford Center.

A new, large study has confirmed that different types of hormone replacement therapy (HRT) are associated with an increased risk for breast cancer and has provided additional information on factors associated with that increased risk.

The study was published online on October 28 in The BMJ.

“The study confirms increased risk of breast cancer in patients taking HRT but shows that the magnitude of risk depends on a number of factors,” first author Yana Vinogradova, PhD, said in an interview. Dr. Vinogradova is a medical statistician at the University of Nottingham (England).

The study also suggests the risk may be lower than was estimated in a large meta-analysis of 24 trials that was published in 2019 in The Lancet. In that study, researchers suggested the risk for breast cancer with HRT was higher and persisted longer than had been thought.

This conclusion from the meta-analysis was widely reported in the lay press and led to the UK Medicine and Healthcare Products Regulatory Agency issuing a safety alert for HRT regarding breast cancer. Experts in the field questioned the alert and said it caused undue anxiety. The European Medicines Agency also issued a safety alert because of the study.

This new study was begun before publication of the meta-analysis. Although the results are broadly similar in suggesting increased risk for breast cancer with HRT use, findings from the new study suggest the risk is lower than had been estimated in the meta-analysis and that the risk diminishes more rapidly after stopping HRT than was suggested by the meta-analysis.

“The publicity surrounding publication of the meta-analysis highlighted unexpectedly high risks and led to a heightened level of concern in some quarters,” Dr. Vinogradova commented. “Our study, based on general population data, has not confirmed any such findings. In general, it showed lower levels of risk and clarified the variability of magnitude within them.”

Dr. Vinogradova said the discrepancy could be related to the fact that the studies were designed differently. The meta-analysis relied on results from 24 studies that were conducted around the world at different periods and included women of different ages and backgrounds. The studies in the meta-analysis used different methods, including questionnaires that relied on women’s memories and therefore could have been biased, she said.

In contrast, the new study analyzed EMR data collected prospectively by general practices in the United Kingdom. The data came from the QResearch and from the Clinical Practice Research Datalink (CPRD) databases, the two largest primary care databases in the United Kingdom, which were linked to hospital, mortality, and cancer registries.

Because this study used a “consistent design” and “consistent data sources,” these new results “are likely to be more accurate and reliable for assessing risks among HRT users,” Dr. Vinogradova commented.

This study used an observational design, so it cannot prove that HRT causes breast cancer. These results may better represent women in the general U.K. population, compared with the earlier meta-analysis, she added.

Commenting on the new study, Michael Jones, PhD, senior staff scientist in genetics and epidemiology at the Institute of Cancer Research, London, also emphasized that it was large and its data came from general practitioner medical records, “so the strong statistical associations are unlikely to be due to chance.

“The results of this study generally confirm what has been seen before and is well established – that the use of combined estrogen plus progestogen HRT is associated with increased risk of breast cancer, and this risk increases with duration of use. But reassuringly, after stopping HRT, the raised risk of breast cancer mostly returns to that seen in nonusers of HRT,” he said.

“It’s important to note that no one study should be considered in isolation,” he added. “Even though some risks were found to be slightly smaller than those reported in another meta-analysis of the worldwide epidemiological evidence recently published in 2019, women considering use of HRT should still follow advice given to them by their [general practitioners].”
 

Study details

In the study, researchers evaluated all types of HRT commonly prescribed in the United Kingdom over the past 20 years, including topical estrogen, vaginal pessaries, and creams. They grouped HRT use by recent (within the past 5 years) and past (5 or more years ago) and HRT duration as short term (less than 5 years) and long term (5 years or longer). Results were adjusted for a range of factors that could affect breast cancer risk, including lifestyle, smoking, alcohol consumption, other medical conditions, family history, and use of other prescribed drugs.

The analysis included 98,611 women aged 50-79 years who were first diagnosed with breast cancer between 1998 and 2019. These women were matched by age and general practice to 457,498 women who were not diagnosed with breast cancer over these years. HRT use was reported in 34% (33,703) of women with breast cancer and in 31% (134,391) of women without breast cancer.

Overall, the risk for breast cancer was increased with use of most HRT drugs (adjusted odds ratio, 1.21; 95% confidence, 1.19-1.23), compared with not using HRT drugs. The highest risk was tied to combined estrogen/progestogen HRT (adjusted OR, 1.26; 95% CI, 1.24-1.29). The lowest risk was tied to estrogen-only HRT (adjusted OR, 1.06; 95% CI, 1.03-1.10). Estrogen cream and vaginal estrogen were not associated with increased breast cancer risk.

In general, breast cancer risk was higher among recent HRT users and those receiving long-term therapy. HRT-associated breast cancer risk increased with age and declined after discontinuing treatment. Therapy of less than 1 year was not associated with increased breast cancer risk.

Women who had recently been receiving long-term combined estrogen/progestogen HRT had a 79% increased risk for breast cancer (adjusted OR, 1.79; 95% CI, 1.73-1.85), compared with never-users. Among recent long-term users of combined HRT, breast cancer risk was highest for norethisterone (adjusted OR, 1.88; 95% CI, 1.79-1.99) and lowest for dydrogesterone (adjusted OR, 1.24; 95% CI, 1.03-1.48). Women who had recently been receiving long-term estrogen-only HRT had a 15% increased risk for breast cancer compared to never-users (adjusted OR, 1.15; 95% CI, 1.09-1.21).

Among women who discontinued HRT 5 or more years ago, risk for breast cancer was no longer increased for long-term estrogen-only therapy and short-term estrogen/progestogen therapy. However, breast cancer risk remained elevated 5 years after discontinuing long-term estrogen/progestogen (adjusted OR, 1.16; 95% CI, 1.11-1.21).

HRT-associated risk for breast cancer increased with age across all durations of therapy.

Compared with never-use, recent long-term estrogen-only therapy was associated with zero extra breast cancer cases per 10,000 women-years among women aged 50-59 years and eight extra cases per 10,000 women-years among women aged 70-79.

Recent long-term estrogen/progestogen use was associated with 15 extra breast cancer cases among women aged 50-59 and 36 extra cases among women aged 70-79 per 10,000 women-years.

Past long-term estrogen/progestogen use was associated with zero extra breast cancer cases among women aged 50-59 and eight extra cases among women aged 70-79 per 10,000 women-years.

Summarizing, Dr. Vinogradova said the increased risk for breast cancer with HRT appears to be “relatively small, particularly for younger women and for any women who use HRT only for a restricted period.”

A routine scan used to evaluate some acute stroke patients can also detect SARS-CoV-2 infection in the upper lungs, a new study shows.

“As part of the stroke evaluation workup process, we were able to diagnose COVID-19 at the same time at no extra cost or additional workload,” lead author Charles Esenwa, MD, commented to Medscape Medical News. “This is an objective way to screen for COVID-19 in the acute stroke setting,” he added.

Esenwa is an assistant professor and a stroke neurologist at the Montefiore Medical Center/Albert Einstein College of Medicine in New York City.

He explained that, during the COVID-19 surge earlier this year, assessment of patients with severe acute stroke using computed tomography angiogram (CTA) scans – used to evaluate suitability for endovascular stroke therapy – also showed findings in the upper lung consistent with viral infection in some patients.

“We then assumed that these patients had COVID-19 and took extra precautions to keep them isolated and to protect staff involved in their care. It also allowed us to triage these patients more quickly than waiting for the COVID-19 swab test and arrange the most appropriate care for them,” Esenwa said.

The researchers have now gone back and analyzed their data on acute stroke patients who underwent CTA at their institution during the COVID-19 surge. They found that the changes identified in the lungs were highly specific for diagnosing SARS-CoV-2 infection.

The study was published online on Oct. 29 in Stroke.

“Stroke patients are normally screened for COVID-19 on hospitalization, but the swab test result can take several hours or longer to come back, and it is very useful for us to know if a patient could be infected,” Esenwa noted.

“When we do a CTA, we look at the blood vessels supplying the brain, but the scan also covers the top of the lung, as it starts at the aortic arch. We don’t normally look closely at that area, but we started to notice signs of active lung infection which could have been COVID-19,” he said. “For this paper, we went back to assess how accurate this approach actually was vs. the COVID-19 PCR test.”

The researchers report on 57 patients who presented to three Montefiore Health System hospitals in the Bronx, in New York City, with acute ischemic stroke and who underwent CTA of the head and neck in March and April 2020, the peak of the COVID-19 outbreak there. The patients also underwent PCR testing for COVID-19.

Results showed that 30 patients had a positive COVID-19 test result and that 27 had a negative result. Lung findings highly or very highly suspicious for COVID-19 pneumonia were identified during the CTA scan in 20 (67%) of the COVID-19–positive patients and in two (7%) of the COVID-19–negative patients.

These findings, when used in isolation, yielded a sensitivity of 0.67 and a specificity of 0.93. They had a positive predictive value of 0.19, a negative predictive value of 0.99, and accuracy of 0.92 for the diagnosis of COVID-19.

When apical lung assessment was combined with self-reported clinical symptoms of cough or dyspnea, sensitivity for the diagnosis of COVID-19 for patients presenting to the hospital for acute ischemic stroke increased to 0.83.

“We wondered whether looking at the whole lung would have found better results, but other studies which have done this actually found similar numbers to ours, so we think actually just looking at the top of the lungs, which can be seen in a stroke CTA, may be sufficient,” Esenwa said.

He emphasized the importance of establishing whether an acute stroke patient has COVID-19. “If we had a high suspicion of COVID-19 infection, we would take more precautions during any procedures, such as thrombectomy, and make sure to keep the patient isolated afterwards. It doesn’t necessarily affect the treatment given for stroke, but it affects the safety of the patients and everyone caring for them,” he commented.

Esenwa explained that intubation – which is sometime necessary during thrombectomy – can expose everyone in the room to aerosolized droplets. “So we would take much higher safety precautions if we thought the patient was COVID-19 positive,” he said.

“Early COVID-19 diagnosis also means patients can be given supportive treatment more quickly, admitted to ICU if appropriate, and we can all keep a close eye on pulmonary issues. So having that information is important in many ways,” he added.

Esenwa advises that any medical center that evaluates acute stroke patients for thrombectomy and is experiencing a COVID-19 surge can use this technique as a screening method for COVID-19.

He pointed out that the Montefiore Health System had a very high rate of COVID-19. That part of New York City was one of the worst hit areas of the world, and the CTA approach for identifying COVID-19 has been validated only in areas with such a high local incidence of COVID. If used in an area of lower prevalence, the accuracy would likely be less.

“We don’t know if this approach would work as well at times of low COVID-19 infection, where any lung findings would be more likely to be caused by other conditions, such as pneumonia due to other causes or congestive heart failure. So there would be more false positives,” Esenwa said.

“But when COVID-19 prevalence is high, the lung findings are much more likely to be a sign of COVID-19 infection. As COVID-19 numbers are now rising for a second time, it is likely to become a useful strategy again.”

The study was approved by the Albert Einstein College of Medicine/Montefiore Medical Center Institutional Review Board and had no external funding. Esenwa has disclosed no relevant financial relationships.

A cumulative 511,000 lives could be lost from COVID-19 in the United States by the end of February 2021, a new prediction study reveals.

However, if universal mask wearing is adopted — defined as 95% of Americans complying with the protective measure — along with social distancing mandates as warranted, nearly 130,000 of those lives could be saved.

And if even 85% of Americans comply, an additional 95,800 lives would be spared before March of next year, researchers at the University of Washington Institute for Health Metrics and Evaluation (IHME) report.

The study was published online October 23 in Nature Medicine.

“The study is sound and makes the case for mandatory mask policies,” said Arthur L. Caplan, PhD, a professor of bioethics at NYU Langone Health in New York City, who frequently provides commentary for Medscape.

Without mandatory mask requirements, he added, “we will see a pandemic slaughter and an overwhelmed healthcare system and workforce.”

The IHME team evaluated COVID-19 data for cases and related deaths between February 1 and September 21. Based on this data, they predicted the likely future of SARS-CoV-2 infections on a state level from September 22, 2020, to February 2021.

An Optimistic Projection

Lead author Robert C. Reiner Jr and colleagues looked at five scenarios. For example, they calculated likely deaths associated with COVID-19 if adoption of mask and social distancing recommendations were nearly universal. They note that Singapore achieved a 95% compliance rate with masks and used this as their “best-case scenario” model.

An estimated 129,574 (range, 85,284–170,867) additional lives could be saved if 95% of Americans wore masks in public, their research reveals. This optimistic scenario includes a “plausible reference” in which any US state reaching 8 COVID-19 deaths per 1 million residents would enact 6 weeks of social distancing mandates (SDMs).

Achieving this level of mask compliance in the United States “could be sufficient to ameliorate the worst effects of epidemic resurgences in many states,” the researchers note.

In contrast, the proportion of Americans wearing masks in public as of September 22 was 49%, according to IHME data.
 

Universal mask use unlikely

“I’m not a modeling expert, but it is an interesting, and as far as I can judge, well-conducted study which looks, state by state, at what might happen in various scenarios around masking policies going forward — and in particular the effect that mandated masking might have,” Trish Greenhalgh, MD, told Medscape Medical News.  

“However, the scenario is a thought experiment. Near-universal mask use is not going to happen in the USA, nor indeed in any individual state, right now, given how emotive the issue has become,” added Greenhalgh, professor in the Nuffield Department of Primary Care Health Sciences at Oxford University, UK. She was not affiliated with the study.

“Hence, whilst I am broadly supportive of the science,” she said, “I’m not confident that this paper will be able to change policy.”
 

Other ‘What if?’ scenarios

The authors also predicted the mortality implications associated with lower adherence to masks, the presence or absence of SDMs, and what could happen if mandates continue to ease at their current rate.

For example, they considered a scenario with less-than-universal mask use in public, 85%, along with SDMs being reinstated based on the mortality rate threshold. In this instance, they found an additional 95,814 (range, 60,731–133,077) lives could be spared by February 28.

Another calculation looked at outcomes if 95% of Americans wore masks going forward without states instituting SDMs at any point. In this case, the researchers predict that 490,437 Americans would die from COVID-19 by February 2021.

A fourth analysis revealed what would happen without greater mask use if the mortality threshold triggered 6 weeks of SDMs as warranted. Under this ‘plausible reference’ calculation, a total 511,373 Americans would die from COVID-19 by the end of February.

A fifth scenario predicted potential mortality if states continue easing SDMs at the current pace. “This is an alternative scenario to the more probable situation where states are expected to respond to an impending health crisis by reinstating some SDMs,” the authors note. The predicted number of American deaths appears more dire in this calculation. The investigators predict cumulative total deaths could reach 1,053,206 (range, 759,693–1,452,397) by the end of February 2021.

The death toll would likely vary among states in this scenario. California, Florida, and Pennsylvania would like account for approximately one third of all deaths.

All the modeling scenarios considered other factors including pneumonia seasonality, mobility, testing rates, and mask use per capita.
 

“I have seen the IHME study and I agree with the broad conclusions,” Richard Stutt, PhD, of the Epidemiology and Modelling Group at the University of Cambridge, UK, told Medscape Medical News.

“Case numbers are climbing in the US, and without further intervention, there will be a significant number of deaths over the coming months,” he said.

Masks are low cost and widely available, Stutt said. “I am hopeful that even if masks are not widely adopted, we will not see as many deaths as predicted here, as these outbreaks can be significantly reduced by increased social distancing or lockdowns.”

“However this comes at a far higher economic cost than the use of masks, and still requires action,” added Stutt, who authored a study in June that modeled facemasks in combination with “lock-down” measures for managing the COVID-19 pandemic.

Modeling study results depend on the assumptions researchers make, and the IHME team rightly tested a number of different assumptions, Greenhalgh said.

“The key conclusion,” she added, “is here: ‘The implementation of SDMs as soon as individual states reach a threshold of 8 daily deaths per million could dramatically ameliorate the effects of the disease; achieving near-universal mask use could delay, or in many states, possibly prevent, this threshold from being reached and has the potential to save the most lives while minimizing damage to the economy.’ “

“This is a useful piece of information and I think is borne out by their data,” added Greenhalgh, lead author of an April study on face masks for the public during the pandemic.

This optimistic scenario includes a “plausible reference” in which any US state reaching 8 COVID-19 deaths per 1 million residents would enact 6 weeks of social distancing mandates (SDMs).

Achieving this level of mask compliance in the United States “could be sufficient to ameliorate the worst effects of epidemic resurgences in many states,” the researchers note.

In contrast, the proportion of Americans wearing masks in public as of September 22 was 49%, according to IHME data.
 

Universal mask use unlikely

“I’m not a modeling expert, but it is an interesting, and as far as I can judge, well-conducted study which looks, state by state, at what might happen in various scenarios around masking policies going forward — and in particular the effect that mandated masking might have,” Trish Greenhalgh, MD, told Medscape Medical News.  

“However, the scenario is a thought experiment. Near-universal mask use is not going to happen in the USA, nor indeed in any individual state, right now, given how emotive the issue has become,” added Greenhalgh, professor in the Nuffield Department of Primary Care Health Sciences at Oxford University, UK. She was not affiliated with the study.

“Hence, whilst I am broadly supportive of the science,” she said, “I’m not confident that this paper will be able to change policy.”
 

Other ‘What if?’ scenarios

The authors also predicted the mortality implications associated with lower adherence to masks, the presence or absence of SDMs, and what could happen if mandates continue to ease at their current rate.

For example, they considered a scenario with less-than-universal mask use in public, 85%, along with SDMs being reinstated based on the mortality rate threshold. In this instance, they found an additional 95,814 (range, 60,731–133,077) lives could be spared by February 28.

Another calculation looked at outcomes if 95% of Americans wore masks going forward without states instituting SDMs at any point. In this case, the researchers predict that 490,437 Americans would die from COVID-19 by February 2021.

A fourth analysis revealed what would happen without greater mask use if the mortality threshold triggered 6 weeks of SDMs as warranted. Under this ‘plausible reference’ calculation, a total 511,373 Americans would die from COVID-19 by the end of February.

A fifth scenario predicted potential mortality if states continue easing SDMs at the current pace. “This is an alternative scenario to the more probable situation where states are expected to respond to an impending health crisis by reinstating some SDMs,” the authors note. The predicted number of American deaths appears more dire in this calculation. The investigators predict cumulative total deaths could reach 1,053,206 (range, 759,693–1,452,397) by the end of February 2021.

The death toll would likely vary among states in this scenario. California, Florida, and Pennsylvania would like account for approximately one third of all deaths.

All the modeling scenarios considered other factors including pneumonia seasonality, mobility, testing rates, and mask use per capita.
 

“I have seen the IHME study and I agree with the broad conclusions,” Richard Stutt, PhD, of the Epidemiology and Modelling Group at the University of Cambridge, UK, told Medscape Medical News.

“Case numbers are climbing in the US, and without further intervention, there will be a significant number of deaths over the coming months,” he said.

Masks are low cost and widely available, Stutt said. “I am hopeful that even if masks are not widely adopted, we will not see as many deaths as predicted here, as these outbreaks can be significantly reduced by increased social distancing or lockdowns.”

“However this comes at a far higher economic cost than the use of masks, and still requires action,” added Stutt, who authored a study in June that modeled facemasks in combination with “lock-down” measures for managing the COVID-19 pandemic.

Modeling study results depend on the assumptions researchers make, and the IHME team rightly tested a number of different assumptions, Greenhalgh said.

“The key conclusion,” she added, “is here: ‘The implementation of SDMs as soon as individual states reach a threshold of 8 daily deaths per million could dramatically ameliorate the effects of the disease; achieving near-universal mask use could delay, or in many states, possibly prevent, this threshold from being reached and has the potential to save the most lives while minimizing damage to the economy.’ “

“This is a useful piece of information and I think is borne out by their data,” added Greenhalgh, lead author of an April study on face masks for the public during the pandemic.

A cumulative 511,000 lives could be lost from COVID-19 in the United States by the end of February 2021, a new prediction study reveals.

However, if universal mask wearing is adopted — defined as 95% of Americans complying with the protective measure — along with social distancing mandates as warranted, nearly 130,000 of those lives could be saved.

And if even 85% of Americans comply, an additional 95,800 lives would be spared before March of next year, researchers at the University of Washington Institute for Health Metrics and Evaluation (IHME) report.

The study was published online October 23 in Nature Medicine.

“The study is sound and makes the case for mandatory mask policies,” said Arthur L. Caplan, PhD, a professor of bioethics at NYU Langone Health in New York City, who frequently provides commentary for Medscape.

Without mandatory mask requirements, he added, “we will see a pandemic slaughter and an overwhelmed healthcare system and workforce.”

The IHME team evaluated COVID-19 data for cases and related deaths between February 1 and September 21. Based on this data, they predicted the likely future of SARS-CoV-2 infections on a state level from September 22, 2020, to February 2021.

An Optimistic Projection

Lead author Robert C. Reiner Jr and colleagues looked at five scenarios. For example, they calculated likely deaths associated with COVID-19 if adoption of mask and social distancing recommendations were nearly universal. They note that Singapore achieved a 95% compliance rate with masks and used this as their “best-case scenario” model.

An estimated 129,574 (range, 85,284–170,867) additional lives could be saved if 95% of Americans wore masks in public, their research reveals. This optimistic scenario includes a “plausible reference” in which any US state reaching 8 COVID-19 deaths per 1 million residents would enact 6 weeks of social distancing mandates (SDMs).

Video capsule endoscopy (VCE) offers an alternative triage tool for acute GI bleeding that may reduce personnel exposure to SARS-CoV-2, based on a cohort study with historical controls.

VCE should be considered even when rapid coronavirus testing is available, as active bleeding is more likely to be detected when evaluated sooner, potentially sparing patients from invasive procedures, reported lead author Shahrad Hakimian, MD, of the University of Massachusetts Medical Center, Worchester, and colleagues.

“Endoscopists and staff are at high risk of exposure to coronavirus through aerosols, as well as unintended, unrecognized splashes that are well known to occur frequently during routine endoscopy,” Dr. Hakimian said during a virtual presentation at the annual meeting of the American College of Gastroenterology.

Although pretesting and delaying procedures as needed may mitigate risks of viral exposure, “many urgent procedures, such as endoscopic evaluation of gastrointestinal bleeding, can’t really wait,” Dr. Hakimian said.

Current guidelines recommend early upper endoscopy and/or colonoscopy for evaluation of GI bleeding, but Dr. Hakimian noted that two out of three initial tests are nondiagnostic, so multiple procedures are often needed to find an answer.

In 2018, a randomized, controlled trial coauthored by Dr. Hakimian’s colleagues demonstrated how VCE may be a better approach, as it more frequently detected active bleeding than standard of care (adjusted hazard ratio, 2.77; 95% confidence interval, 1.36-5.64).

The present study built on these findings in the context of the COVID-19 pandemic.

Dr. Hakimian and colleagues analyzed data from 50 consecutive, hemodynamically stable patients with severe anemia or suspected GI bleeding who underwent VCE as a first-line diagnostic modality from mid-March to mid-May 2020 (COVID arm). These patients were compared with 57 consecutive patients who were evaluated for acute GI bleeding or severe anemia with standard of care prior to the COVID-19 pandemic (pre-COVID arm).

Characteristics of the two cohorts were generally similar, although the COVID arm included a slightly older population, with a median age of 68 years, compared with a median age of 61.8 years for the pre-COVID arm (P = .03). Among presenting symptoms, hematochezia was less common in the COVID group (4% vs. 18%; P = .03). Comorbidities were not significantly different between cohorts.

Per the study design, 100% of patients in the COVID arm underwent VCE as their first diagnostic modality. In the pre-COVID arm, 82% of patients first underwent upper endoscopy, followed by colonoscopy (12%) and VCE (5%).

The main outcome, bleeding localization, did not differ between groups, whether this was confined to the first test, or in terms of final localization. But VCE was significantly better at detecting active bleeding or stigmata of bleeding, at a rate of 66%, compared with 28% in the pre-COVID group (P < .001). Patients in the COVID arm were also significantly less likely to need any invasive procedures (44% vs. 96%; P < .001).

No intergroup differences were observed in rates of blood transfusion, in-hospital or GI-bleed mortality, rebleeding, or readmission for bleeding.

“VCE appears to be a safe alternative to traditional diagnostic evaluation of GI bleeding in the era of COVID,” Dr. Hakimian concluded, noting that “the VCE-first strategy reduces the risk of staff exposure to endoscopic aerosols, conserves personal protective equipment, and reduces staff utilization.”

According to Neil Sengupta, MD, of the University of Chicago, “a VCE-first strategy in GI bleeding may be a useful triage tool in the COVID-19 era to determine which patients truly benefit from invasive endoscopy,” although he also noted that “further data are needed to determine the efficacy and safety of this approach.”

Lawrence Hookey, MD, of Queen’s University, Kingston, Ont., had a similar opinion.

“VCE appears to be a reasonable alternative in this patient group, at least as a first step,” Dr. Hookey said. “However, whether it truly makes a difference in the decision making process would have to be assessed prospectively via a randomized controlled trial or a decision analysis done in real time at various steps of the patient’s care path.”

Erik A. Holzwanger, MD, a gastroenterology fellow at Tufts Medical Center in Boston, suggested that these findings may “serve as a foundation” for similar studies, “as it appears COVID-19 will be an ongoing obstacle in endoscopy for the foreseeable future.”

“It would be interesting to have further discussion of timing of VCE, any COVID-19 transmission to staff during the VCE placement, and discussion of what constituted proceeding with endoscopic intervention [high-risk lesion, active bleeding] in both groups,” he added.

David Cave, MD, PhD, coauthor of the present study and the 2015 ACG clinical guideline for small bowel bleeding, said that VCE is gaining ground as the diagnostic of choice for GI bleeding, and patients prefer it, since it does not require anesthesia.

“This abstract is another clear pointer to the way in which, we should in the future, investigate gastrointestinal bleeding, both acute and chronic,” Dr. Cave said. “We are at an inflection point of transition to a new technology.”

Dr. Cave disclosed relationships with Medtronic and Olympus. The other investigators and interviewees reported no conflicts of interest.

Half of Chinese American parents and their children report having experienced an in-person episode of racial discrimination related to the COVID-19 pandemic, according to results from a survey study.

In the United States, where public officials continue to refer to SARS-CoV-2 as the “China virus” and have often sought to draw attention to its origins in Wuhan, China, “the associations between discrimination triggered by the racialization of this acute public health crisis and mental health are unknown,” Charissa S.L. Cheah, PhD, of the University of Maryland, Baltimore County, and colleagues wrote.

For their research published Oct. 29 in Pediatrics, Dr. Cheah and colleagues recruited a cohort of 543 Chinese American parents of school-age children, and 230 of their children aged 10-18 years, to complete online surveys between mid-March and late May 2020. Parents in the cohort were largely foreign born, with all identifying as ethnically Chinese, while their children were mostly U.S. born.
 

Evidence of discrimination against Chinese Americans

Half of parents and their children (51% of parents and 50% of youth) reported experiencing at least one in-person incident of direct discrimination (assessed using questions derived from a validated scale of racial aggression) related to the pandemic. Dr. Cheah and colleagues also reported a high incidence of direct discrimination online (32% of parents and 46% of youth). Additionally, the researchers measured reports of vicarious or indirect discrimination – such as hearing jokes or disparaging remarks about one’s ethnic group – which they used a different adapted scale to capture. More than three-quarters of the cohort reported such experiences.

The experiences of discrimination likely bore on the mental health of both parents and youth. Using a series of instruments designed to measure overall psychological well-being as well as symptoms of depression, anxiety, and certain emotional and behavioral outcomes, Dr. Cheah and colleagues reported significant negative associations between direct online or in-person discrimination and psychological health. For parents and children alike, anxiety and depressive symptoms were positively associated with all varieties of discrimination experiences measured in the study.

About a fifth of the youth in the study were deemed, based on the symptom scales used in the study, to have an elevated risk of clinically significant mental health problems, higher than the 10%-15% that would be expected for these age groups in the United States.

“This study revealed that a high percentage of Chinese American parents and their children personally experienced or witnessed anti-Chinese or anti–Asian American racial discrimination both online and in person due to the COVID-19 pandemic,” the investigators wrote. “Most respondents reported directly experiencing or witnessing racial discrimination against other Chinese or Asian American individuals due to COVID-19 at least once.”

Dr. Cheah and colleagues noted that their cross-sectional study did not lend itself to causal interpretations and was vulnerable to certain types of reporting bias. Nonetheless, they argued, as the pandemic continues, “pediatricians should be sensitive to the potential mental health needs of Chinese American youth and their parents related to various forms of racism, in addition to other stressors, as the foundations of perceptions of racial-ethnic discrimination and their consequences may be set during this period.”
 

COVID-19 didn’t only bring infection

In an accompanying editorial, Tina L. Cheng, MD, of Johns Hopkins University, Baltimore, and her daughter Alison M. Conca-Cheng, a medical student at Brown University, Providence, R.I., remarked that the study’s findings were consistent with recent research that found “4 in 10 Americans reported that it has become more common since COVID-19 for people to express racist views about Asian Americans,” and also described an increase in complaints of discriminatory experiences by Asian Americans.

In this context, a link to poor mental health “should be no surprise,” Dr. Cheng and Ms. Conca-Cheng argued, and urged pediatricians to consult the American Academy of Pediatrics’ 2019 policy statement on racism and on child and adolescent health. “It calls for us to optimize clinical practice, improve workforce development and professional education, strengthen research, and deploy systems through community engagement, advocacy, and public policy.”

David Rettew, MD, a child and adolescent psychiatrist and associate professor of psychiatry and pediatrics at the University of Vermont, Burlington, called the study’s main points “clear and disturbing.”

“While it is difficult to find much in the way here of a silver lining, these alarming reports have helped people working in health care and mental health to understand racism as another form of trauma and abuse which, like other types, can have real negative effects on health,” Dr. Rettew said in an interview. “The more we as mental health professions ask about racism and offer resources for people who have experienced it, just as we would people who have endured other types of trauma, the more we can help people heal. That said, it would be better just to stop this from happening in the first place.”

Dr. Cheah and colleagues’ study was supported by a National Science Foundation grant. The investigators disclosed no conflicts of interest. Dr. Cheng and Ms. Conca-Cheng disclosed no financial conflicts of interest related to their editorial. Dr. Rettew said he had no relevant financial disclosures.

“This study revealed that a high percentage of Chinese American parents and their children personally experienced or witnessed anti-Chinese or anti–Asian American racial discrimination both online and in person due to the COVID-19 pandemic,” the investigators wrote. “Most respondents reported directly experiencing or witnessing racial discrimination against other Chinese or Asian American individuals due to COVID-19 at least once.”

Dr. Cheah and colleagues noted that their cross-sectional study did not lend itself to causal interpretations and was vulnerable to certain types of reporting bias. Nonetheless, they argued, as the pandemic continues, “pediatricians should be sensitive to the potential mental health needs of Chinese American youth and their parents related to various forms of racism, in addition to other stressors, as the foundations of perceptions of racial-ethnic discrimination and their consequences may be set during this period.”
 

COVID-19 didn’t only bring infection

In an accompanying editorial, Tina L. Cheng, MD, of Johns Hopkins University, Baltimore, and her daughter Alison M. Conca-Cheng, a medical student at Brown University, Providence, R.I., remarked that the study’s findings were consistent with recent research that found “4 in 10 Americans reported that it has become more common since COVID-19 for people to express racist views about Asian Americans,” and also described an increase in complaints of discriminatory experiences by Asian Americans.

In this context, a link to poor mental health “should be no surprise,” Dr. Cheng and Ms. Conca-Cheng argued, and urged pediatricians to consult the American Academy of Pediatrics’ 2019 policy statement on racism and on child and adolescent health. “It calls for us to optimize clinical practice, improve workforce development and professional education, strengthen research, and deploy systems through community engagement, advocacy, and public policy.”

David Rettew, MD, a child and adolescent psychiatrist and associate professor of psychiatry and pediatrics at the University of Vermont, Burlington, called the study’s main points “clear and disturbing.”

“While it is difficult to find much in the way here of a silver lining, these alarming reports have helped people working in health care and mental health to understand racism as another form of trauma and abuse which, like other types, can have real negative effects on health,” Dr. Rettew said in an interview. “The more we as mental health professions ask about racism and offer resources for people who have experienced it, just as we would people who have endured other types of trauma, the more we can help people heal. That said, it would be better just to stop this from happening in the first place.”

Dr. Cheah and colleagues’ study was supported by a National Science Foundation grant. The investigators disclosed no conflicts of interest. Dr. Cheng and Ms. Conca-Cheng disclosed no financial conflicts of interest related to their editorial. Dr. Rettew said he had no relevant financial disclosures.

Half of Chinese American parents and their children report having experienced an in-person episode of racial discrimination related to the COVID-19 pandemic, according to results from a survey study.

In the United States, where public officials continue to refer to SARS-CoV-2 as the “China virus” and have often sought to draw attention to its origins in Wuhan, China, “the associations between discrimination triggered by the racialization of this acute public health crisis and mental health are unknown,” Charissa S.L. Cheah, PhD, of the University of Maryland, Baltimore County, and colleagues wrote.

For their research published Oct. 29 in Pediatrics, Dr. Cheah and colleagues recruited a cohort of 543 Chinese American parents of school-age children, and 230 of their children aged 10-18 years, to complete online surveys between mid-March and late May 2020. Parents in the cohort were largely foreign born, with all identifying as ethnically Chinese, while their children were mostly U.S. born.
 

Evidence of discrimination against Chinese Americans

Half of parents and their children (51% of parents and 50% of youth) reported experiencing at least one in-person incident of direct discrimination (assessed using questions derived from a validated scale of racial aggression) related to the pandemic. Dr. Cheah and colleagues also reported a high incidence of direct discrimination online (32% of parents and 46% of youth). Additionally, the researchers measured reports of vicarious or indirect discrimination – such as hearing jokes or disparaging remarks about one’s ethnic group – which they used a different adapted scale to capture. More than three-quarters of the cohort reported such experiences.

The experiences of discrimination likely bore on the mental health of both parents and youth. Using a series of instruments designed to measure overall psychological well-being as well as symptoms of depression, anxiety, and certain emotional and behavioral outcomes, Dr. Cheah and colleagues reported significant negative associations between direct online or in-person discrimination and psychological health. For parents and children alike, anxiety and depressive symptoms were positively associated with all varieties of discrimination experiences measured in the study.

About a fifth of the youth in the study were deemed, based on the symptom scales used in the study, to have an elevated risk of clinically significant mental health problems, higher than the 10%-15% that would be expected for these age groups in the United States.

Two experts at IDWeek 2020 debated the best treatment for patients with the most severe type of Clostridioides difficile infection – fulminant C. diff. The discussion pitted fecal microbiota transplants (FMT) from the stool of healthy donors against traditional antibiotics.

Fulminant C. diff infection (CDI) represents about 8% of all CDI cases and is often fatal. Patients frequently don’t respond to maximum antibiotic therapy.

Should these patients be treated with FMT before surgery is considered?

“Unequivocally, yes,” said Jessica R. Allegretti, MD, MPH, associate director of the Crohn’s and Colitis Center at Brigham and Women’s Hospital in Boston.
 

Patients face full colectomy

Fulminant infection, she says, typically requires a total abdominal colectomy with end ileostomy.

“Patients have a quite high perioperative and intraoperative mortality because this is typically an older population with significant comorbidities,” she said.

Often the patients are poor candidates for surgery, she added.

She pointed to the efficacy of FMT in studies such as one published in Gut Microbes in 2017. The study, by Monika Fischer, MD, of Indiana University, Indianapolis, and colleagues showed a 91% cure rate at 1 month in severe patients with an average of 1.5 fecal transplants, noting that was “quite remarkable” in this very sick population.

Though FMT is not approved by the US Food and Drug Administration for fulminant CDI, Dr. Allegretti said, the FDA does allow treatment under “enforcement discretion,” which means no investigational new drug license is needed specifically if treating CDI patients who haven’t responded to standard therapy, as long as proper consent has been obtained.

“This is a patient population that is likely going to die,” she said. “If you were the one in the ICU with fulminant C. diff and you’ve been on maximum therapy for 3-5 days and you’re not getting better, wouldn’t you want somebody to offer you a fecal transplant and give you the chance to recover and leave the hospital with your colon intact? The data suggest that is possible, with a high likelihood and a good safety profile.”

She said the most recent guidelines have supported FMT, and emerging guidelines coming within months “will support this as well.”
 

Unknowns with FMT

Taking the other side of the debate, Kevin Garey, PharmD, chair of the department of pharmacy practice and translational research at University of Houston College of Pharmacy, warned against trading traditional antibiotics, such as vancomycin and fidaxomicin, for the novelty of FMT.

“With the science of the microbiome and the novelty of fecal microbiota transplantation in expanding use, I think people have somewhat forgotten pharmacotherapy,” he said.

He pointed out safety concerns with FMT reported in June 2019, after which the FDA issued an alert. Two immunocompromised patients who received FMT, both from the same donor, developed invasive infections caused by extended-spectrum beta-lactamase (ESBL)–producing Escherichia coli. One died.

The FDA explained that the donated FMT samples the patients received were not tested for ESBL-producing gram-negative organisms before use.

Dr. Allegretti agreed antibiotics play a role in treatment with FMT, but she argued that the safety profile of FMT remains strong and that the safety issues came from isolated incidents at a single center.

Dr. Garey countered that there are just too many unknowns with FMT.

“We will never know what the next superbug that’s going to land in an FMT is until we’ve identified that superbug in somebody – the next Candida auris, the next CRE [carbapenem-resistant Enterobacteriaceae], the next thing that’s going to show up in FMT – until we get rid of the ‘F,’ “ Dr. Garey said.

“[Until] we get microbial therapy that’s generated without the need for healthy donors, I think we’re always going to be in this problem.”

He said although FMT “has an amazing ability to alter a microbiome” it “pales in comparison” to vancomycin’s ability to do so.

Disruption of the microbiome is, without a doubt, a hallmark of C. diff, but we don’t have to run to FMT,” Dr. Garey said. “We can think about prophylaxis strategies, we can think about new drug development that spares the microbiota. The need for FMT might be a consequence of poor pharmacotherapy management, not a part of pharmacotherapy management.”

Moderator Sam Aitken, PharmD, MPH, a clinical pharmacy specialist in infectious disease at MD Anderson Cancer Center in Houston, said in an interview the speakers found some common ground.

“I think there was a general consensus between both Dr. Allegretti and Dr. Garey that both traditional therapeutics and fecal microbiota transplantation have a role to play in these patients, although there is still quite a bit of discussion around where those might be best positioned,” Dr. Aitken said.

He added, “There’s also a general consensus that there is not likely to be one right answer for all patients with multiple recurrent CDI.”

Dr. Allegretti, Dr. Garey, and Dr. Aitken have disclosed no relevant financial relationships.

For patients with diabetic kidney disease, finerenone, an agent from a new class of selective, nonsteroidal mineralocorticoid receptor antagonists, led to significant reductions in combined adverse renal outcomes and in combined adverse cardiovascular outcomes in the pivotal FIDELIO-DKD trial.

And the safety results showed a good level of tolerability. The rate of hyperkalemia was higher with finerenone than with placebo, but the rate of drug discontinuations for elevated potassium was lower than that seen with spironolactone, a steroidal mineralocorticoid receptor antagonist (MRA).

“An ideal drug would cause no hyperkalemia, but the absolute risk we saw is a fraction of what we see with spironolactone in this vulnerable patient population,” said Rajiv Agarwal, MD, from Indiana in Indianapolis, during a press briefing.

After a median follow-up of 2.6 years, finerenone was associated with a 3.4% absolute reduction in the rate of combined adverse renal events, the study’s primary end point, which comprised kidney failure, renal death, and a drop in estimated glomerular filtration rate (eGFR) of at least 40% from baseline. This produced a significant relative risk reduction of 18%, with a number needed to treat of 32 to prevent one of these events, Dr. Agarwal reported at Kidney Week 2020. Findings from the FIDELIO-DKD trial were published simultaneously in the New England Journal of Medicine.

Finerenone was also associated with an absolute 2.4% reduction in the rate of combined adverse cardiovascular events, the study’s “key secondary end point,” which included cardiovascular death, nonfatal MI, nonfatal stroke, and hospitalization for heart failure. This translated into a significant relative risk reduction of 14% and a number needed to treat of 42 to prevent one of these events.

FIDELIO-DKD assessed 5,734 patients with type 2 diabetes and chronic kidney disease from more than 1,000 sites in 48 countries, including the United States, from 2015 to 2018. In the study cohort, average age was slightly more than 65 years, average baseline systolic blood pressure was 138 mm Hg, average duration of diabetes was nearly 17 years, average baseline glycated hemoglobin (A1c) was 7.7%, and fewer than 5% of patients were Black, 25% were Asian, and about 63% were White.
 

A suggestion of less severe hyperkalemia

Finerenone was well tolerated by the participants, and the findings suggest that it caused less clinically meaningful hyperkalemia than spironolactone, the most established and widely used MRA.

Like all MRA drugs, finerenone led to an increase in serum potassium in all patient subgroups – in this case 0.2 mmol/L – unlike placebo, said Dr. Agarwal.

The overall incidence of hyperkalemia was 16% in the 2,827 evaluable patients in the finerenone group and 8% in the 2,831 evaluable patients in the placebo group. Fewer than 10% of patients in the trial received a potassium-binding agent.

The rate of hyperkalemia leading to treatment discontinuation was higher in the finerenone group than in the placebo group (2.3% vs. 0.9%).

That 2.3% rate is 10 times lower than the 23.0% rate of hyperkalemia-related treatment discontinuation in patients who received spironolactone and no potassium-binding agent, said Dr. Agarwal, citing a previous study he was involved with.

He hypothesized that finerenone might cause less clinically meaningful hyperkalemia because it creates no active metabolites that linger in the body, whereas spironolactone produces active metabolites with a half life of about 1 week.

“The risk for hyperkalemia is clearly increased with finerenone compared with placebo, and in the absence of head-to-head studies, it’s hard to know how it compares with spironolactone or eplerenone [Inspra],” the other agents in the MRA class, said Mikhail N. Kosiborod, MD, from the University of Missouri–Kansas City.

“The rates of hyperkalemia observed in FIDELIO-DKD were overall comparable to what we would expect from eplerenone. But the rate of serious hyperkalemia was quite low with finerenone, which is reassuring,” Dr. Kosiborod said in an interview.

And the adverse-effect profile showed that finerenone “is as safe as you could expect from an MRA,” said Janani Rangaswami, MD, from the Einstein Medical Center in Philadelphia.

The rate of hyperkalemia should be interpreted in the context of the high risk the enrolled patients faced, given that they all had moderate to severe diabetic kidney disease with albuminuria and, in some cases, eGFR rates as low as 25 mL/min per 1.73m², she explained. In addition, all patients were on maximally tolerated treatment with either an angiotensin-converting–enzyme inhibitor or an angiotensin receptor blocker to inhibit the renin angiotensin system (RAS).

“Considering this background, it’s a very acceptable adverse-event profile,” Dr. Rangaswami said in an interview.
 

Renal drugs that could work together

More than 99% of patients in FIDELIO-DKD were on an RAS inhibitor, but fewer than 5% were on a sodium glucose cotransporter 2 (SGLT2) inhibitor at baseline, and fewer than 10% started on this drug class during the course of the study.

Despite that, both Dr. Kosiborod and Dr. Rangaswami are enthusiastic about the prospect of using the three drugs in combination to maximize renal and cardiovascular benefits in FIDELIO-DKD–type patients. Recent results from the CREDENCE study of canagliflozin (Invokana) and from the DAPA-CKD study of dapagluflozin (Farxiga) have established SGLT2 inhibitors – at least those two – as key agents for patients with chronic kidney disease.

Dual treatment with an RAS inhibitor and an SGLT2 inhibitor is “clearly established” for patients with diabetic kidney disease, said Dr. Agarwal.

“After CREDENCE, DAPA-CKD, and now FIDELIO-DKD, we need to seriously consider triple therapy as the future of treatment for diabetic kidney disease to prevent both cardiovascular and kidney complications,” said Dr. Kosiborod. The approach will mimic the multidrug therapy that’s now standard for patients with heart failure with reduced ejection fraction (HFrEF). But he cautioned that this triple combination needs further testing.

“Triple therapy will be the standard of care” for patients with diabetic kidney disease, Dr. Rangaswami agreed, but she cautioned that she would not currently expand the target population for finerenone to patients without type 2 diabetes or to patients without the level of albuminuria required for entry into FIDELIO-DKD: at least 30 mg/g of creatinine per day. And patients with HFrEF were excluded from FIDELIO-DKD, so that limitation on finerenone use should remain for the time being, she added.

Dr. Rangaswami said she is optimistic about the potential efficacy of finerenone added to an SGLT2 inhibitor because of the likelihood that the two drug classes work in different but complementary ways. SGLT2 inhibitors seem to exert their renal protective effects largely through hemodynamic effects, whereas it is likely that finerenone exerts its effects largely as an anti-inflammatory and antifibrotic agent, she speculated. The FIDELIO-DKD results appear to rule out any major effect of finerenone on blood pressure lowering because average systolic pressure fell by only about 2 mm Hg in the treatment group.

“The benefits of finerenone for cardiorenal outcomes are substantial and clinically meaningful,” Dr. Kosiborod said. “We cannot assume that other MRAs, such as spironolactone, provide similar benefits,” he cautioned, but the results are “very good news for patients with type 2 diabetes and chronic kidney disease. We now have another effective intervention with a different mechanism of action.”

FIDELIO-DKD was sponsored by Bayer, the company developing finerenone (BAY 94-8862). Dr. Agarwal has been a consultant to and has received honoraria from Bayer and from several other companies. Dr. Kosiborod has been a consultant to Bayer and to AstraZeneca, Boehringer Ingelheim, Jansse, Merck, and Vifor and has received research funding from AstraZeneca and Boehringer Ingelheim. Dr. Rangaswami has disclosed no relevant financial relationships.

That 2.3% rate is 10 times lower than the 23.0% rate of hyperkalemia-related treatment discontinuation in patients who received spironolactone and no potassium-binding agent, said Dr. Agarwal, citing a previous study he was involved with.

He hypothesized that finerenone might cause less clinically meaningful hyperkalemia because it creates no active metabolites that linger in the body, whereas spironolactone produces active metabolites with a half life of about 1 week.

“The risk for hyperkalemia is clearly increased with finerenone compared with placebo, and in the absence of head-to-head studies, it’s hard to know how it compares with spironolactone or eplerenone [Inspra],” the other agents in the MRA class, said Mikhail N. Kosiborod, MD, from the University of Missouri–Kansas City.

“The rates of hyperkalemia observed in FIDELIO-DKD were overall comparable to what we would expect from eplerenone. But the rate of serious hyperkalemia was quite low with finerenone, which is reassuring,” Dr. Kosiborod said in an interview.

And the adverse-effect profile showed that finerenone “is as safe as you could expect from an MRA,” said Janani Rangaswami, MD, from the Einstein Medical Center in Philadelphia.

The rate of hyperkalemia should be interpreted in the context of the high risk the enrolled patients faced, given that they all had moderate to severe diabetic kidney disease with albuminuria and, in some cases, eGFR rates as low as 25 mL/min per 1.73m², she explained. In addition, all patients were on maximally tolerated treatment with either an angiotensin-converting–enzyme inhibitor or an angiotensin receptor blocker to inhibit the renin angiotensin system (RAS).

“Considering this background, it’s a very acceptable adverse-event profile,” Dr. Rangaswami said in an interview.
 

Renal drugs that could work together

More than 99% of patients in FIDELIO-DKD were on an RAS inhibitor, but fewer than 5% were on a sodium glucose cotransporter 2 (SGLT2) inhibitor at baseline, and fewer than 10% started on this drug class during the course of the study.

Despite that, both Dr. Kosiborod and Dr. Rangaswami are enthusiastic about the prospect of using the three drugs in combination to maximize renal and cardiovascular benefits in FIDELIO-DKD–type patients. Recent results from the CREDENCE study of canagliflozin (Invokana) and from the DAPA-CKD study of dapagluflozin (Farxiga) have established SGLT2 inhibitors – at least those two – as key agents for patients with chronic kidney disease.

Dual treatment with an RAS inhibitor and an SGLT2 inhibitor is “clearly established” for patients with diabetic kidney disease, said Dr. Agarwal.

“After CREDENCE, DAPA-CKD, and now FIDELIO-DKD, we need to seriously consider triple therapy as the future of treatment for diabetic kidney disease to prevent both cardiovascular and kidney complications,” said Dr. Kosiborod. The approach will mimic the multidrug therapy that’s now standard for patients with heart failure with reduced ejection fraction (HFrEF). But he cautioned that this triple combination needs further testing.

“Triple therapy will be the standard of care” for patients with diabetic kidney disease, Dr. Rangaswami agreed, but she cautioned that she would not currently expand the target population for finerenone to patients without type 2 diabetes or to patients without the level of albuminuria required for entry into FIDELIO-DKD: at least 30 mg/g of creatinine per day. And patients with HFrEF were excluded from FIDELIO-DKD, so that limitation on finerenone use should remain for the time being, she added.

Dr. Rangaswami said she is optimistic about the potential efficacy of finerenone added to an SGLT2 inhibitor because of the likelihood that the two drug classes work in different but complementary ways. SGLT2 inhibitors seem to exert their renal protective effects largely through hemodynamic effects, whereas it is likely that finerenone exerts its effects largely as an anti-inflammatory and antifibrotic agent, she speculated. The FIDELIO-DKD results appear to rule out any major effect of finerenone on blood pressure lowering because average systolic pressure fell by only about 2 mm Hg in the treatment group.

“The benefits of finerenone for cardiorenal outcomes are substantial and clinically meaningful,” Dr. Kosiborod said. “We cannot assume that other MRAs, such as spironolactone, provide similar benefits,” he cautioned, but the results are “very good news for patients with type 2 diabetes and chronic kidney disease. We now have another effective intervention with a different mechanism of action.”

FIDELIO-DKD was sponsored by Bayer, the company developing finerenone (BAY 94-8862). Dr. Agarwal has been a consultant to and has received honoraria from Bayer and from several other companies. Dr. Kosiborod has been a consultant to Bayer and to AstraZeneca, Boehringer Ingelheim, Jansse, Merck, and Vifor and has received research funding from AstraZeneca and Boehringer Ingelheim. Dr. Rangaswami has disclosed no relevant financial relationships.

For patients with diabetic kidney disease, finerenone, an agent from a new class of selective, nonsteroidal mineralocorticoid receptor antagonists, led to significant reductions in combined adverse renal outcomes and in combined adverse cardiovascular outcomes in the pivotal FIDELIO-DKD trial.

And the safety results showed a good level of tolerability. The rate of hyperkalemia was higher with finerenone than with placebo, but the rate of drug discontinuations for elevated potassium was lower than that seen with spironolactone, a steroidal mineralocorticoid receptor antagonist (MRA).

“An ideal drug would cause no hyperkalemia, but the absolute risk we saw is a fraction of what we see with spironolactone in this vulnerable patient population,” said Rajiv Agarwal, MD, from Indiana in Indianapolis, during a press briefing.

After a median follow-up of 2.6 years, finerenone was associated with a 3.4% absolute reduction in the rate of combined adverse renal events, the study’s primary end point, which comprised kidney failure, renal death, and a drop in estimated glomerular filtration rate (eGFR) of at least 40% from baseline. This produced a significant relative risk reduction of 18%, with a number needed to treat of 32 to prevent one of these events, Dr. Agarwal reported at Kidney Week 2020. Findings from the FIDELIO-DKD trial were published simultaneously in the New England Journal of Medicine.

Finerenone was also associated with an absolute 2.4% reduction in the rate of combined adverse cardiovascular events, the study’s “key secondary end point,” which included cardiovascular death, nonfatal MI, nonfatal stroke, and hospitalization for heart failure. This translated into a significant relative risk reduction of 14% and a number needed to treat of 42 to prevent one of these events.

FIDELIO-DKD assessed 5,734 patients with type 2 diabetes and chronic kidney disease from more than 1,000 sites in 48 countries, including the United States, from 2015 to 2018. In the study cohort, average age was slightly more than 65 years, average baseline systolic blood pressure was 138 mm Hg, average duration of diabetes was nearly 17 years, average baseline glycated hemoglobin (A1c) was 7.7%, and fewer than 5% of patients were Black, 25% were Asian, and about 63% were White.
 

A suggestion of less severe hyperkalemia

Finerenone was well tolerated by the participants, and the findings suggest that it caused less clinically meaningful hyperkalemia than spironolactone, the most established and widely used MRA.

Like all MRA drugs, finerenone led to an increase in serum potassium in all patient subgroups – in this case 0.2 mmol/L – unlike placebo, said Dr. Agarwal.

The overall incidence of hyperkalemia was 16% in the 2,827 evaluable patients in the finerenone group and 8% in the 2,831 evaluable patients in the placebo group. Fewer than 10% of patients in the trial received a potassium-binding agent.

The rate of hyperkalemia leading to treatment discontinuation was higher in the finerenone group than in the placebo group (2.3% vs. 0.9%).

That 2.3% rate is 10 times lower than the 23.0% rate of hyperkalemia-related treatment discontinuation in patients who received spironolactone and no potassium-binding agent, said Dr. Agarwal, citing a previous study he was involved with.

Eli Lilly announced it will halt its ACTIV-3 trial evaluating the antibody bamlanivimab in combination with remdesivir for people hospitalized with COVID-19, after new evidence regarding efficacy emerged.

The new data from the National Institutes of Health suggest that the experimental neutralizing antibody therapy does not offer significant clinical benefit for people with more advanced COVID-19 illness, according to a company statement.

Eli Lilly also announced it plans to continue its other trials evaluating the antibody, including those assessing a potential role in treating people in the earlier stages of COVID-19.

“While there was insufficient evidence that bamlanivimab improved clinical outcomes when added to other treatments in hospitalized patients with COVID-19, we remain confident based on data from Lilly’s BLAZE-1 study that bamlanivimab monotherapy may prevent progression of disease for those earlier in the course of COVID-19,” the statement reads.

The ACTIV-3 trial was paused on October 13 after a data and safety monitoring board cited safety concerns.

The most recent data update that triggered an end to the trial did not reveal any significant differences in safety, though.

A new algorithm on lipid management and prevention of cardiovascular disease from the American Association of Clinical Endocrinologists* (AACE) and the American College of Endocrinology (ACE) is “a nice cookbook” that many clinicians, especially those who are not lipid experts, will find useful, according to writing committee chair Yehuda Handelsman, MD.

The algorithm, published Oct. 10 in Endocrine Practice as 10 slides, or as part of a more detailed consensus statement, is a companion to the 2017 AACE/ACE guidelines for lipid management and includes more recent information about new therapies.

“What we’re trying to do here is to say, ‘focus on LDL-C, triglycerides, high-risk patients, and lifestyle. Understand all the medications available to you to reduce LDL-C and reduce triglycerides,’ ” Dr. Handelsman, of the Metabolic Institute of America, Tarzana, Calif., explained in an interview.

“We touch on lipoprotein(a), which we still don’t have medication for, but it identifies people at high risk, and we need that.”

Clinicians also need to know “that we’ve got some newer drugs in the market that can manage people who have statin intolerance,” Dr. Handelsman added.

“We introduced new therapies like icosapent ethyl” (Vascepa, Amarin) for hypertriglyceridemia, “when to use it, and how to use it. Even though it was not part of the 2017 guideline, we gave recommendations based on current data in the algorithm.”

Although there is no good evidence that lowering triglycerides reduces heart disease, he continued, many experts believe that the target triglyceride level should be less than 150 mg/dL, and the algorithm explains how to treat to this goal.

“Last, and most importantly, I cannot fail to underscore the fact that lifestyle is very important,” he emphasized.

Robert H. Eckel, MD, of the University of Colorado at Denver, Aurora, and president of medicine and science at the American Diabetes Association, who was not involved with this algorithm, said in an interview that the algorithm is important since it offers “the clinician or health care practitioner an approach, a kind of a cookbook or application of the guidelines, for how to manage lipid disorders in patients at risk ... It’s geared for the nonexperts too,” he said.

Dyslipidemia treatment summarized in 10 slides

The AACE/ACE algorithm comprises 10 slides, one each for dyslipidemic states, secondary causes of lipid disorders, screening for and assessing lipid disorders and atherosclerotic CVD (ASCVD) risk, ASCVD risk categories and treatment goals, lifestyle recommendations, treating LDL-C to goal, managing statin intolerance and safety, management of hypertriglyceridemia and the role of icosapent ethyl, assessment and management of elevated lipoprotein(a), and profiles of medications for dyslipidemia.

The algorithm defines five ASCVD risk categories and recommends increasingly lower LDL-C, non–HDL-C, and apo B target levels with increasing risk, but the same triglyceride target for all.

First, “treatment of lipid disorders begins with lifestyle therapy to improve nutrition, physical activity, weight, and other factors that affect lipids,” the consensus statement authors stress.

Next, “LDL-C has been, and remains, the main focus of efforts to improve lipid profiles in individuals at risk for ASCVD” (see table).

Statement aligns with major guidelines

In general, the 2017 AACE/ACE guidelines and algorithm are “pretty similar” to other guidelines such as the 2018 ACC/American Heart Association (AHA) guidelines for cholesterol management, the 2019 ACC/AHA guidelines for primary prevention of CVD, and the 2019 European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) guidelines for the management of dyslipidemia, according to Dr. Eckel.

They have “all have now taken into consideration the evidence behind PCSK9 inhibitors,” he noted. “That’s important because those drugs have proven to be effective.”

Two differences, he pointed out, are that the 2019 ESC/EAS guidelines suggest that lipoprotein(a) measurement be considered at least once in every adult’s lifetime, and they recommend apo B analysis in people with high triglycerides but normal LDL (or no higher than 100 mg/dL), to identify additional risk.
 

*AACE changes its name, broadens focus

Shortly after its algorithm was published, AACE announced that it has a new organization name and brand, the American Association of Clinical Endocrinology, which “more clearly defines AACE as a community of individuals who work together to elevate the practice of clinical endocrinology,” according to an Oct. 20 statement.

The change is meant to acknowledge AACE’s “more modern, inclusive approach to endocrinology that supports multidisciplinary care teams – with endocrinologists leading the way.”

Along with the name change is a new global website. The statement notes that “health care professionals and community members can access all of the valuable clinical content such as guidelines, disease state networks and important education by visiting the pro portal in the top right corner of the site, or by going directly to pro.aace.com.”

Dr. Handelsman discloses that he receives research grant support from Amgen, Applied Therapeutics, AstraZeneca, BMS, Gan & Lee, Novo Nordisk, and Sanofi, and he is a consultant and/or speaker for Amarin, BI-Lilly, and Sanofi.

Dr. Eckel has received consultant/advisory board fees from Kowa, Novo Nordisk, and Provention Bio.
