Systemic lupus erythematosus remains a treatment challenge, but a variety of drugs in the pipeline are set to target type I interferons, cytokines, and B cells, according to Richard Furie, MD, chief of the division of rheumatology at Northwell Health and professor of medicine at Hofstra University, Hempstead, N.Y.

In general, when treating patients with systemic lupus erythematosus (SLE), “we just don’t see satisfactory response rates,” Dr. Furie said in an online presentation at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education.

“I think the greatest unmet need is in lupus nephritis,” he said. The data show that not even one-third of patients are adequately responding to standard of care treatment. “We need to do better in lupus nephritis but also for those patients with moderate-severe manifestations outside the kidney.”

Patients with SLE have elevated levels of interferon-alpha, Dr. Furie noted. Data from recent studies show that interferon inhibitors can reduce clinical activity in SLE patients, he said.

“About two-thirds to three-quarters of lupus patients have evidence of interferon pathway activation,” he said. There are three types of interferons, and five subtypes of type I interferon, and all five subtypes of type I interferon bind to the same receptor, which is an important strategy for drug development.

In particular, recent phase 2 and 3 trials have focused on targeting type I interferons with anifrolumab, which blocks all five subtypes.

Dr. Furie cited “very robust results” from a phase 2 study. Results of two phase 3 trials of anifrolumab led to a split decision, but the totality of the data collected across the phase 2 and 3 studies points to a drug that is effective for patients with SLE. The two phase 3 studies were published in Lancet Rheumatology and the New England Journal of Medicine.

Dr. Furie also identified recent studies of baricitinib (Olumiant), which has the ability to target several different cytokines. A phase 2 study in 2018 showed a significant difference in SLE Responder Index between lupus patients who received 4 mg of baricitinib or placebo, and a phase 3 study is underway, he said.

For lupus nephritis, Dr. Furie cited the BLISS-LN trial, a 104-week, randomized trial of patients with active lupus nephritis. The group of patients who received belimumab (Benlysta), a monoclonal antibody that targets B-cell activating factor, in addition to standard therapy had significant improvements in renal responses, compared with standard therapy alone (43.0% vs. 32.3%). The outcome measure was Primary Efficacy Renal Response, defined as urinary protein/creatinine ratio <0.7, eGFR ≥60 mL/min per 1.73 m², confirmation on consecutive visits, and required tapering of background glucocorticoids.

Although belimumab was approved for SLE in 2011, the BLISS-LN study focused on SLE patients with active kidney disease. “Neutralizing B-cell activating factor and down-regulating autoreactive B-cell function in kidneys represented a compelling therapeutic approach to lupus nephritis,” he explained.

Voclosporin, distinct from cyclosporine, has also been studied in lupus nephritis, Dr. Furie said. Voclosporin offers several benefits over cyclosporine, including greater potency and a lower drug and metabolite load, as well as a more consistent pharmacokinetic and pharmacodynamic relationship, he said. In the phase 3 AURORA study, presented at this year’s EULAR congress, 40% of patients with lupus nephritis met the primary endpoint of a renal response at 52 weeks, compared with 22.5% of placebo patients.

Looking ahead to the treatment of SLE in 2021, “I feel very strongly that voclosporin will be approved for lupus nephritis,” he said. He also predicted that the use of belimumab will be officially extended for lupus nephritis and that anifrolumab will receive an approval for SLE patients.

In addition, the future may witness the increased use of biomarkers and development of more individualized therapy. These breakthroughs will yield better outcomes for all lupus patients, he said.

Widespread treatment of hepatitis C virus significantly reduced the risk of hepatocellular carcinoma, based on 18 years of data from patients in Veterans Health Administration hospitals.

Although eradication of hepatitis C virus (HCV) infections has been shown to reduce the risk of hepatocellular carcinoma (HCC), effective direct-acting antiviral therapies available since 2013 appear underused in the United States, with a 14% cure rate for HCV patients as of 2016, wrote Lauren A. Beste, MD, of Veterans Affairs Puget Sound Health Care System, Seattle, and colleagues.

However, “the Veterans Health Administration, the largest integrated health care system in the U.S., provides unrestricted access to HCV treatments and approximately 85% of its case load has achieved cure,” the researchers said.

In a letter published in JAMA, the researchers identified all patients in the VHA diagnosed with HCC based on electronic health records for each year between 2002 and 2018. HCV infection was based on any history of detectable viral load, and HCV cure was defined as a negative viral load at least 12 weeks following completion of antiviral treatment, the researchers said.

“We categorized patients into 3 groups as of the time of HCC diagnosis: HCC/HCV viremic (latest HCV RNA before HCC diagnosis was positive), HCC/HCV cured (HCV eradicated before HCC diagnosis), and HCC/non-HCV (no positive lifetime HCV RNA),” they explained.

The sum of HCC/HCV viremic plus HCC/HCV cured made up the HCC/HCV total. Overall, the incidence of HCC/HCV total increased from 2000 to 2015, peaked at 31.0 per 100,000 patients in 2015, and decreased to 21.8 per 100,000 in 2018 after the introduction of viral eradication efforts from 2014 to 2016.
 

HCV treatment shows value despite lack of causality

Although the study could not prove causality, “the timing of HCV eradication and declining HCC incidence, lack of decline in non–HCV-related HCC, and prior studies demonstrating that HCV eradication reduces HCC risk, provide indirect evidence that this decline may be related to widespread HCV treatment,” the researchers said.

The findings were limited by several factors including the observational study design, use of the International Classification of Diseases to define HCC, use of a VA population that might limit generalizability, and lack of data on the severity of disease prior to treatment, the researchers noted. However, “HCC incidence trends should continue to be monitored closely because patients cured of HCV may have yet to experience the full potential of risk reduction,” and the study results support large-scale campaigns to eliminate HCV as well as monitoring for HCC and HCV patients who achieve disease eradication, they concluded.

The study was supported in part by grants from the National Institutes of Health/National Cancer Institute and the Veterans Affairs Clinical Science Research and Development. The researchers had no financial conflicts to disclose.

A history of liver transplant conveyed no increased risk of death from COVID-19 infections, according to data from a multicenter cohort study of 151 transplant recipients who became infected.

Although current data suggest a possible increased risk of adverse outcomes if liver transplant patients develop COVID-19 infections, the effects remain unclear, wrote Gwilym J. Webb, PhD, of the University of Oxford (England) and colleagues.

In a study published in the Lancet Gastroenterology & Hepatology, the researchers identified adults from 18 countries who had laboratory-confirmed COVID-19 infections between March 25, 2020, and June 26, 2020. The average age of the patients was 60 years, and 68% were men. A contemporaneous group of 627 consecutive adults with confirmed COVID-19 infections who had not undergone liver transplants served as controls.

Overall, 28 of the liver transplant patients and 167 of the controls died (19% vs. 27%; P = .046).

In addition, no differences appeared between infected transplant patients and infected controls in terms of hospitalization (82% vs. 76%) and the need for intensive care (31% vs. 30%), although the transplant patients were significantly more likely to require invasive ventilation (20% vs. 5%).

However, in a multivariate analysis, older age, serum creatinine concentration, and the presence of nonliver cancers were independently associated with increased risk of death in the liver transplant patients, with odds ratios of 1.06 for each year increase in age, 1.57 for each mg/dL increase in serum creatinine concentration, and 18.30 with the presence of a nonliver cancer.

The study findings were limited by several factors including the potential overreporting of severe COVID-19 cases because of reporting bias in the transplant registry, as well as the inability of the sample size to rule out mortality differences, the differences in comorbidities between the transplant patients and controls, and the impact of unmeasured confounding variables such as diet, physical activity, or fibrosis or cirrhosis in recipient grafts, the researchers noted. However, the results suggest that a history of liver transplantation does not increase the risk of death following COVID-19 infection, they wrote.

“Thus, traditional risk factors for adverse outcomes from COVID-19 should be preferentially considered when considering the risks and benefits of hospital attendance, immunosuppression, and social-distancing requirements for liver transplant recipients during the ongoing COVID-19 pandemic,” they concluded.

Focus on comorbidities and combined transplants

“Given that age and presence of comorbidities were significantly associated with risk of death in the cohorts of patients who had and had not undergone liver transplantation, greater emphasis should be placed on other coexisting comorbidities, rather than transplantation status per se, when risk-stratifying liver transplant recipients,” the researchers noted. “Indirectly, these findings suggest that liver transplantation, where indicated, should not be delayed during the COVID-19 pandemic, and that supportive care should not be limited for patients with existing liver transplants with COVID-19,” they suggested.

Given the high prevalence of COVID-19 in many countries, “it is inevitable that liver transplant patients will become infected,” said Wajahat Mehal, MD, of Yale University, New Haven, Conn., in an interview.

Going forward, “it is important to know the natural history of COVID in the immunocompromised population,” he emphasized.

One of the study limitations was the lack of data on how patients’ immunosuppression regimens were changed, if at all, while they were infected. “Since some other immunocompromised patients have had a higher rate of complications [in the wake of COVID-19 infections], I was pleasantly surprised that liver transplant recipients did so well,” Dr. Mehal said.

Dr. Mehal noted that additional research is needed to promote safety in patients with liver disease in the context of COVID-19. “It would be important to evaluate combined transplants, particularly combined liver/kidney transplants,” he said.

The study was supported by the European Association for the Study of the Liver, the National Institutes of Health, and the United Kingdom National Institute for Health Research. Lead author Dr. Webb had no financial conflicts to disclose. One coauthor disclosed unrelated fees from AbbVie and grants from the Fondation du Centre Hospitalier de l’Université de Montréal.

Although recent reports suggest that COVID-19 infections in children are generally mild, data on the full spectrum of illness and duration of viral RNA in children are limited, wrote Mi Seon Han, MD, PhD, of Seoul (South Korea) Metropolitan Government–Seoul National University Boramae Medical Center, and colleagues.

To examine the full clinical course and duration of COVID-19 RNA detectability in children with confirmed infections, the researchers reviewed data from 91 individuals with confirmed infections. The children ranged in age from 27 days to 18 years, and 58% were male. The children were monitored at 20 hospitals and 2 isolation facilities for a mean 21.9 days. The findings were published in JAMA Pediatrics.

Overall, COVID-19 viral RNA was present in the study population for a mean 17.6 days, with testing done at a median interval of 3 days. A total of 20 children (22%) were asymptomatic throughout the study period. In these children, viral RNA was detected for a mean 14 days.

“The major hurdle implicated in this study in diagnosing and treating children with COVID-19 is that a considerable number of children are asymptomatic, and even if symptoms are present, they are unrecognized and overlooked before COVID-19 is diagnosed,” the researchers noted.

Of the 71 symptomatic children, 47 (66%) had unrecognized symptoms prior to diagnosis, 18 (25%) developed symptoms after diagnosis, and 6 (9%) were diagnosed at the time of symptom onset. The symptomatic children were symptomatic for a median of 11 days; 43 (61%) remained symptomatic at 7 days’ follow-up after the study period, 27 (38%) were symptomatic at 14 days, and 7 (10%) were symptomatic at 21 days.

A total of 41 children had upper respiratory infections (58%) and 22 children (24%) had lower respiratory tract infections. No difference in the duration of virus RNA was detected between children with upper respiratory tract infections and lower respiratory tract infections (average, 18.7 days vs. 19.9 days).

Among the symptomatic children, 46 (65%) had mild cases and 20 (28%) had moderate cases.

For treatment, 14 children (15%) received lopinavir-ritonavir and/or hydroxychloroquine. Two patients had severe illness and received oxygen via nasal prong, without the need for mechanical ventilation. All the children in the case series recovered from their infections with no fatalities.

The study’s main limitation was the inability to analyze the transmission potential of the children because of the quarantine and isolation policies in Korea, the researchers noted. In addition, the researchers did not perform follow-up testing at consistent intervals, so the duration of COVID-19 RNA detection may be inexact.

However, the results suggest “that suspecting and diagnosing COVID-19 in children based on their symptoms without epidemiologic information and virus testing is very challenging,” the researchers emphasized.

“Most of the children with COVID-19 have silent disease, but SARS-CoV-2 RNA can still be detected in the respiratory tract for a prolonged period,” they wrote. More research is needed to explore the potential for disease transmission by children in the community, and increased surveillance with laboratory screening can help identify children with unrecognized infections.

The study is the first known to focus on the frequency of asymptomatic infection in children and the duration of symptoms in both asymptomatic and symptomatic children, Roberta L. DeBiasi, MD, and Meghan Delaney, DO, both affiliated with Children’s National Hospital and Research Institute, Washington, and George Washington University, Washington, wrote in an accompanying editorial. The structure of the Korean public health system “allowed for the sequential observation, testing (median testing interval of every 3 days), and comparison of 91 asymptomatic, presymptomatic, and symptomatic children with mild to moderate upper and lower respiratory tract infection, identified primarily by contact tracing from laboratory-proven cases.”

Two take-home points from the study are that not all infected children are symptomatic, and the duration of symptoms in those who are varies widely, they noted. “Interestingly, this study aligns with adult data in which up to 40% of adults may remain asymptomatic in the face of infection.”

However, “The third and most important take-home point from this study relates to the duration of viral shedding in infected pediatric patients,” Dr. DeBiasi and Dr. Delaney said (JAMA Pediatr. 2020 Aug 28. doi: 10.1001/jamapediatrics.2020.3996).

“Fully half of symptomatic children with both upper and lower tract disease were still shedding virus at 21 days. These are striking data, particularly since 86 of 88 diagnosed children (98%) either had no symptoms or mild or moderate disease,” they explained. The results highlight the need for improvements in qualitative molecular testing and formal studies to identify differences in results from different testing scenarios, such as hospital entry, preprocedure screening, and symptomatic testing. In addition, “these findings are highly relevant to the development of public health strategies to mitigate and contain spread within communities, particularly as affected communities begin their recovery phases.”

The study is important because “schools are opening, and we don’t know what is going to happen,” Michael E. Pichichero, MD, of Rochester General Hospital, N.Y., said in an interview.

“Clinicians, parents, students, school administrators and politicians are worried,” he said. “This study adds to others recently published, bringing into focus the challenges to several suppositions that existed when the COVID-19 pandemic began and over the summer.”

“This study of 91 Korean children tells us that taking a child’s temperature as a screening tool to decide if they may enter school will not be a highly successful strategy,” he said. “Many children are without fever and asymptomatic when infected and contagious. The notion that children shed less virus or shed it for shorter lengths of time we keep learning from this type of research is not true. In another recent study the authors found that children shed as much of the SARS-CoV-2 virus as an adult in the ICU on a ventilator.”

Dr. Pichichero said he was not surprised by the study findings. “A similar paper was published last week in the Journal of Pediatrics from Massachusetts General Hospital, so the findings in the JAMA paper are similar to what has been reported in the United States.”

“Availability of testing will continue to be a challenge in some communities,” said Dr. Pichichero. “Here in the Rochester, New York, area we will use a screening questionnaire based on the CDC [Centers for Disease Control and Prevention] symptom criteria of SARS-CoV-2 infections to decide whom to test.”

As for additional research, “We have so much more to learn about SARS-CoV-2 in children,” he emphasized. “The focus has been on adults because the morbidity and mortality has been greatest in adults, especially the elderly and those with compromised health.”

“The National Institutes of Health has issued a call for more research in children to characterize the spectrum of SARS-CoV-2 illness, including the multisystem inflammatory syndrome in children [MIS-C] and try to identify biomarkers and/or biosignatures for a prognostic algorithm to predict the longitudinal risk of disease severity after a child is exposed to and may be infected with SARS-CoV-2,” said Dr. Pichichero. “NIH has asked researchers to answer the following questions.”

• Why do children have milder illness?
• Are there differences in childhood biology (e.g., gender, puberty, etc.) that contribute to illness severity?
• Are there genetic host differences associated with different disease severity phenotypes, including MIS-C?
• Are there innate mucosal, humoral, cellular and other adaptive immune profiles that are associated with reduced or increased risk of progressive disease, including previous coronavirus infections?
• Will SARS-CoV-2 reinfection cause worse disease as seen with antibody-dependent enhancement (ADE) in other viral infections (e.g., dengue)? Will future vaccines carry a risk of the ADE phenomenon?
• Does substance use (e.g., nicotine, marijuana) exacerbate or trigger MIS-C through immune activation?

“We have no knowledge yet about SARS-CoV-2 vaccination of children, especially young children,” Dr. Pichichero emphasized. “There are different types of vaccines – messenger RNA, adenovirus vector and purified spike proteins of the virus – among others, but questions remain: Will the vaccines work in children? What about side effects? Will the antibodies and cellular immunity protect partially or completely?”

Early administration of evolocumab significantly reduced levels of LDL cholesterol in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention, according to data from an open-label randomized trial of 102 adults in Japan.

Data from previous studies have shown that proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors can reduce LDL cholesterol in acute coronary syndrome patients, wrote Tomoaki Okada, MD, of Kagawa (Japan) Prefectural Central Hospital and colleagues.

In particular, “The EVOPACS trial [J Am Coll Cardiol 2019; 74:2452-62] reported that evolocumab therapy initiated at an early phase of ACS showed [LDL cholesterol] level reduction by 4-8 weeks,” they said.

“However, the 4-week efficacy of PCSK9 inhibitor therapy combined with a statin remains unknown,” they said.

In a study presented at the virtual annual congress of the European Society of Cardiology and published simultaneously in JACC: Cardiovascular Interventions, the researchers randomized 52 patients to receive 140 mg of evolocumab subcutaneously within 24 hours of indexed percutaneous coronary intervention and again after 2 weeks. A group of 50 controls received evolocumab after PCI only, but no additional dose after 2 weeks.

The average age of the patients was 65 years, 88% were men, and 26% had a history of statin treatment.

A total of 49 patients in each group were included in the final analysis, with a primary outcome of change in LDL cholesterol levels from baseline to 4 weeks.

Baseline LCL cholesterol levels were 120.8 mg/dL and 124.7 mg/dL in the evolocumab and control groups, respectively. Changes from baseline were significantly greater in the evolocumab group, compared with controls, at –76% and –33%, respectively.

All patients in the evolocumab group and 27% of patients in the control groups achieved LDL cholesterol levels of less than 70 mg/dL at 4 weeks. In addition, 92% and 96% of evolocumab patients achieved LDL cholesterol levels less than 55 mg/dL at 2 weeks and 4 weeks, respectively.

Overall changes in non-HDL cholesterol, HDL cholesterol, and small dense LDL in the evolocumab and control groups were –66.2% and –26.0%; 2.8% and –0.7%; and –67% and –13.8%, respectively. Of these, changes in non-HDL cholesterol and small dense LDL were significantly different between the groups.

In addition, patients in the evolocumab group showed a 3% decrease in lipoprotein, compared with an 82% increase in the control group. This finding suggests the additional benefit of including evolocumab for managing residual risk in patients with high lipoprotein(a) levels” after acute MI, the researchers noted.

Adverse events and serious adverse events were similar between the groups.

‘Early and strong’ LDL cholesterol lowering best for preventing repeat events

“By using the PCSK9 inhibitors, we have the opportunity to lower LDL cholesterol [LDL-C]” both quickly and dramatically, said Heinz Drexel, MD, in an interview.

“This Japanese study shows that very low LDL-C levels can be obtained as fast as within 4 weeks,” he said. “This fits into the concept that risk for future infarctions and strokes is best reduced by early and strong LDL-C lowering,” he explained.

Dr. Drexel said that he was not surprised by the magnitude of the decrease in LDL cholesterol in study findings in light of the EVOPACS study and other research, as well as his own clinical experience.

“The primary message for doctors is that it is now possible to achieve these low levels of LDL-C in a short time,” he said.

“Additional research must prove that this low LDL-C translates to reduction of MIs and strokes, and there is increasing evidence that this will happen,” Dr. Drexel noted.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Drexel had no financial conflicts to disclose.

Early administration of evolocumab significantly reduced levels of LDL cholesterol in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention, according to data from an open-label randomized trial of 102 adults in Japan.

Data from previous studies have shown that proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors can reduce LDL cholesterol in acute coronary syndrome patients, wrote Tomoaki Okada, MD, of Kagawa (Japan) Prefectural Central Hospital and colleagues.

In particular, “The EVOPACS trial [J Am Coll Cardiol 2019; 74:2452-62] reported that evolocumab therapy initiated at an early phase of ACS showed [LDL cholesterol] level reduction by 4-8 weeks,” they said.

“However, the 4-week efficacy of PCSK9 inhibitor therapy combined with a statin remains unknown,” they said.

In a study presented at the virtual annual congress of the European Society of Cardiology and published simultaneously in JACC: Cardiovascular Interventions, the researchers randomized 52 patients to receive 140 mg of evolocumab subcutaneously within 24 hours of indexed percutaneous coronary intervention and again after 2 weeks. A group of 50 controls received evolocumab after PCI only, but no additional dose after 2 weeks.

The average age of the patients was 65 years, 88% were men, and 26% had a history of statin treatment.

A total of 49 patients in each group were included in the final analysis, with a primary outcome of change in LDL cholesterol levels from baseline to 4 weeks.

Baseline LCL cholesterol levels were 120.8 mg/dL and 124.7 mg/dL in the evolocumab and control groups, respectively. Changes from baseline were significantly greater in the evolocumab group, compared with controls, at –76% and –33%, respectively.

All patients in the evolocumab group and 27% of patients in the control groups achieved LDL cholesterol levels of less than 70 mg/dL at 4 weeks. In addition, 92% and 96% of evolocumab patients achieved LDL cholesterol levels less than 55 mg/dL at 2 weeks and 4 weeks, respectively.

Overall changes in non-HDL cholesterol, HDL cholesterol, and small dense LDL in the evolocumab and control groups were –66.2% and –26.0%; 2.8% and –0.7%; and –67% and –13.8%, respectively. Of these, changes in non-HDL cholesterol and small dense LDL were significantly different between the groups.

In addition, patients in the evolocumab group showed a 3% decrease in lipoprotein, compared with an 82% increase in the control group. This finding suggests the additional benefit of including evolocumab for managing residual risk in patients with high lipoprotein(a) levels” after acute MI, the researchers noted.

Adverse events and serious adverse events were similar between the groups.

‘Early and strong’ LDL cholesterol lowering best for preventing repeat events

“By using the PCSK9 inhibitors, we have the opportunity to lower LDL cholesterol [LDL-C]” both quickly and dramatically, said Heinz Drexel, MD, in an interview.

“This Japanese study shows that very low LDL-C levels can be obtained as fast as within 4 weeks,” he said. “This fits into the concept that risk for future infarctions and strokes is best reduced by early and strong LDL-C lowering,” he explained.

Dr. Drexel said that he was not surprised by the magnitude of the decrease in LDL cholesterol in study findings in light of the EVOPACS study and other research, as well as his own clinical experience.

“The primary message for doctors is that it is now possible to achieve these low levels of LDL-C in a short time,” he said.

“Additional research must prove that this low LDL-C translates to reduction of MIs and strokes, and there is increasing evidence that this will happen,” Dr. Drexel noted.

Patients with chronic obstructive pulmonary disease who also had certain interstitial lung abnormalities experienced more exacerbations and reduced lung function than those without such abnormalities, findings from a retrospective study has shown.

Interstitial lung abnormalities (ILA) are considered precursor lesions of interstitial lung disease and previous studies suggested an association with poor outcomes among chronic obstructive pulmonary disease (COPD) patients, but data on long-term clinical relevance are limited, wrote Tae Seung Lee, MD, of Seoul (South Korea) National University Hospital, and colleagues.

In a study published in Chest, the researchers reviewed data from 363 COPD patients including 44 with equivocal ILA and 103 with definite ILA. Overall, the ILA patients were older and had poorer lung function than non-ILA patients. Patients received chest CT scan and longitudinal pulmonary function tests between January 2013 and December 2018.

Over an average follow-up period of 5.4 years, patients with ILA experienced significantly more acute COPD exacerbations than did those without ILA (adjusted odds ratio, 2.03). The percentages of frequent exacerbators among patients with no ILA, equivocal ILA, and definite ILA were 8.3%, 15.9%, and 20.4%, respectively.

“Acute exacerbation is an important event during the clinical course of COPD, because it is associated with temporary or persistent reductions in lung function, lower quality of life, hospitalization, and mortality,” the researchers noted.

In a multivariate analysis, the annual decline in lung function (FEV₁) was –35.7 in patients with equivocal ILA, compared with –28.0 in patients with no ILA and –15.9 in those with definite ILA.

“This may be due to the distribution of the spirometric stages in each group, and to the resulting changes in lung function,” the researchers wrote. In this study, “the equivocal ILA group had a significantly lower baseline FEV₁ than the other groups. In our study population, the lower the spirometric stage, the faster the annual decline in FEV₁, consistent with the results of a prior prospective study of a COPD cohort.”

The findings were limited by several factors including the retrospective design and relatively small number of ILA patients, as well as the limited evaluation of ILA and potential for selection bias, the researchers noted. However, the result support the impact of ILA on exacerbations and accelerated decline in lung function in COPD patients.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Microorganisms in the human digestive tract are linked to 29 specific health conditions, including chronic obstructive pulmonary disease, high blood pressure, and type 2 diabetes, according to a genome analysis in more than 400,000 individuals.

European Society of Cardiology

Although previous studies have suggested a link between gut microbiota and diseases in humans, “the extent to which the human gut microbiome can be considered a determinant of disease and healthy aging remains unknown,” Hilde E. Groot, MD, of the University of Groningen (The Netherlands), said in a presentation at the virtual annual congress of the European Society of Cardiology.

To identify the spectrum of diseases linked to the gut microbiome, the researchers identified 422,417 unrelated adults of White British ancestry with genotype and matching genetic data. The average age of the participants was 57 years and 46% were male.

The researchers conducted a phenomewide association study including 35 distinct single-nucleotide polymorphisms (SNPs) that are known to influence the microbiome of the human gut.

Overall, seven SNPs were significantly associated with 29 disease outcomes including hypertension, type 2 diabetes, hypercholesterolemia, heart failure, renal failure, and osteoarthritis.

In addition, after a further sensitivity analysis using a Mendelian randomization (MR) approach, associations between Ruminococcus flavefaciens and hypertension and between Clostridium and platelet count might point to a causal link, the researchers said.

“Over the past few years, the amount of research concerning the human gut microbiome and the associations with health and disease has tremendously increased. However, most studies investigated one or a few traits. The strength of our study is the possibility to cover a wide range of traits simultaneously within one population,” Dr. Groot said in an interview.

“Our data support the hypothesis that the human gut microbiome is a complex system, involved in many pathophysiological mechanisms in the human body. So, our results are additional to earlier research and strengthen this hypothesis,” Dr. Groot added.

“Microbiota and their metabolites might be of importance in the interplay between overlapping pathophysiological processes, and could serve as potential therapeutic targets for the maintenance of health and prevention and treatment of cardiovascular diseases. However, before it is possible to give advice for the public and medical practice, further research is needed to study causality,” she emphasized.

“Currently, it is too soon to advise patients concerning their microbiome,” Dr. Groot noted. “However, genetic studies like ours might help other researchers to study causality between the gut microbiome and particular traits, which might potentially lead to new therapeutic targets. Next to genetic variants as a proxy, we’re currently studying the gut microbiome composition in myocardial infarction patients and healthy controls in a longitudinal setting.”

“Previous studies have suggested a potential link between the gut microbiome and the development of cardiovascular disease, type 2 diabetes mellitus, and other chronic disorders,” Carol Ann Remme, MD, of the Amsterdam University Medical Center, said in an interview. “However, it is challenging to study the effect of gut microbiome composition in large patient cohorts. As an alternative approach, the study authors showed in a very large population that genetic variants previously shown to influence gut microbiome composition were significantly associated with conditions such as hypertension, type 2 diabetes, hypercholesterolemia, and heart failure.”

The study is unique in that it employed a very large cohort of more than 400,000 individuals, which is typically required to be able to draw clear conclusions, Dr. Remme continued. “The authors were able to further refine their findings by linking genetic variants known to influence specific gut bacteria to some particular disorders,” she noted.

“It is becoming increasingly clear that an individual’s gut microbiome composition, which is defined by both genetic and environmental factors such as diet, may affect his/her susceptibility to certain diseases – including cardiovascular – in addition to disease progression and outcome,” said Dr. Remme. “This may ultimately lead to development of novel, personalized strategies for risk stratification in addition to potential preventive measures targeting the gut microbiome. I expect this area of research will become increasingly important in the coming years.”

The study received no outside funding. Dr. Groot and colleagues had no financial conflicts to disclose. Dr. Remme had no financial conflicts to disclose.

Breast milk is an unlikely source of transmission of SARS-CoV-2 from mothers to infants, according to data from case reports and breast milk samples from 18 women.

“To date, SARS-CoV-2 has not been isolated from breast milk, and there are no documented cases of transmission of infectious virus to the infant through breast milk,” but the potential for transmission remains a concern among women who want to breastfeed, wrote Christina Chambers, PhD, of the University of California, San Diego, and colleagues.

In a research letter published in JAMA, the investigators identified 18 women with confirmed SARS-CoV-2 infections (all but 1 of the women had symptomatic COVID-19 disease) and infants aged 0-19 months between March 27 and May 6, 2020. The average age of the mothers was 34 years, and 78% were non-Hispanic White. The women provided 1-12 samples of breast milk for a total of 64 samples collected before and after positive COVID-19 tests.

One sample yielded detectable RNA from SARS-CoV-2 and was collected on the day of the woman’s symptom onset. However, one sample taken 2 days prior to symptom onset and two samples collected 12 and 41 days later tested negative for viral RNA, the researchers said. In addition, no replication-competent virus was identified in the positive sample or any of the other samples.

The researchers spiked two stored milk samples collected prior to the pandemic with replication-competent SARS-CoV-2. Virus was not detected by culture in the samples after Holder pasteurization, but was detected by culture in nonpasteurized aliquots of the same samples.

“These data suggest that SARS-CoV-2 RNA does not represent replication-competent virus and that breast milk may not be a source of infection for the infant,” Dr. Chambers and associates said.

The results were limited by several factors including the small sample size and potential for selection bias, as well as the use of self-reports of positive tests and self-collection of breast milk, the researchers noted. However, the findings are reassuring in light of the known benefits of breastfeeding and the use of milk banks.

“This research is important because the pandemic is ongoing and has far-reaching consequences: as the authors indicate, the potential for viral transmission through breast milk remains a critical question for women infected with SARS-CoV-2 who wish to breastfeed,” Janet R. Hardy, PhD, MPH, MSc, a consultant on global maternal-child health and pharmacoepidemiology, said in an interview.

“This virus has everyone on a rapid learning track, and all information that helps build evidence to support women’s decision-making in the care of their children is valuable,” she said. “These findings suggest that breast milk may not be a source of SARS-CoV-2 infection for the infant. They provide some reassurance given the recognized benefits of breastfeeding and human milk.”

However, “This study is very specific to breast milk,” she emphasized. “In advising women infected with SARS-CoV-2, clinicians may want to include a discussion of protection methods to prevent maternal transmission of the virus through respiratory droplets.”

Although the data are preliminary, “the investigators established and validated an RT-PCR [reverse transcription polymerase chain reaction] assay and developed tissue culture methods for replication-competent SARS-CoV-2 in breast milk, both valuable tools for further studies. Next steps will include controlled studies of greater sample size with independent verification of RT-PCR positivity,” said Dr. Hardy, a consultant to Biohaven Pharmaceuticals, New Haven, Conn.

The study was supported by the National Institute of Allergy and Infectious Diseases, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, and the National Institute of Mental Health. Medela Corporation provided milk sample collection materials. The Family Larsson-Rosenquist Foundation provided an unrestricted COVID19 emergency gift fund.

Although the data are preliminary, “the investigators established and validated an RT-PCR [reverse transcription polymerase chain reaction] assay and developed tissue culture methods for replication-competent SARS-CoV-2 in breast milk, both valuable tools for further studies. Next steps will include controlled studies of greater sample size with independent verification of RT-PCR positivity,” said Dr. Hardy, a consultant to Biohaven Pharmaceuticals, New Haven, Conn.

The study was supported by the National Institute of Allergy and Infectious Diseases, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, and the National Institute of Mental Health. Medela Corporation provided milk sample collection materials. The Family Larsson-Rosenquist Foundation provided an unrestricted COVID19 emergency gift fund. The Mothers’ Milk Bank at Austin paid for shipping costs.

Anorexia nervosa may stunt the growth and impact the future height of teenage girls, according to data from 255 adolescents.

Illness and malnutrition during critical child and adolescent growth periods may limit adult height, but the effect of anorexia nervosa (AN) on growth impairment and adult height has not been well studied, wrote Dalit Modan-Moses, MD, of Chaim Sheba Medical Center, Tel Aviv, and colleagues.

Individuals with AN lose an unhealthy amount of weight on purpose through dieting, sometimes along with excessive exercise, binge eating, and/or purging, and because the condition occurs mainly in adolescents, the subsequent malnutrition may impact growth and adult height, they said.

In a study published in the Journal of Clinical Endocrinology & Metabolism, the researchers reviewed data from 255 adolescent girls who were hospitalized for AN at an average age of 15 years. They measured the girls’ height at the time of hospital admission, discharge, and at adulthood. The participants were followed in an outpatient clinic after hospital discharge with biweekly visits for the first 2 months, monthly visits for the next 4 months, and every 3 months until they reached 18 years of age. The average body mass index of the patients at the time of admission was 16 kg/m² and the average duration of illness was 2 years. Of the 225 patients, 174 had a diagnosis of restrictive type anorexia nervosa and 81 had binge-purge type.

The midparental target height was based on an average of the parents’ heights and subtracting 6.5 cm. The main outcome of adult height was significantly shorter than expected (P = .006) based on midparental target height. Although the patients’ heights increased significantly during hospitalization, from 158 cm to 159 cm (P < .001), “the change in height-SDS [standard deviation scores] was not significant and height-SDS at discharge remained significantly lower compared to the expected in a normal population,” the researchers noted.

Although premorbid height SDS in the study population were similar to normal adolescents, the height-SDS measurements at hospital admission, discharge, and adulthood were significantly lower than expected (–0.36, –0.34, and –0.29, respectively).

Independent predictors of height improvement from hospital admission to adulthood were patient age and bone age at the time of hospital admission, linear growth during hospitalization, and change in luteinizing hormone (LH) during hospitalization, based on a stepwise forward linear regression analysis.

The findings were limited by several factors including the inpatient study population, which may limit the generalizability to patients with less severe illness, as well as incomplete data on LH levels, which were undetectable in 19% of the patients, the researchers noted. However, the study is among the largest to describe growth in female AN patients and included data on linear growth and LH not described in other studies, they said.

“Our study is unique in presenting complete growth data (premorbid, admission, discharge, AH) as well as target height, laboratory results and bone age data in a large cohort of adolescent females with AN,” they wrote.

The findings not only support the need for early intervention in patients with AN and the need for long-term weight gain to achieve catch-up growth, but also may apply to management of malnutrition in adolescents with chronic diseases such as cystic fibrosis and inflammatory bowel disease, they concluded.

“Anorexia nervosa is a prevalent and severe disease with multiple short- and long-term complications. Still, despite the large body of research regarding this disease, data regarding growth patterns and final height of patients was incomplete and inconclusive, Dr. Modan-Moses said in an interview. The findings were not surprising, and were consistent with the results of a previous study the researchers conducted (Modan-Moses D et al. PLoS One. 2012 Sept 18. doi: 10.1371/journal.pone.0045504).

“Our first study was retrospective, and many pertinent parameters influencing growth were not available,” Dr. Modan-Moses noted. “The current study was designed to include a comprehensive evaluation including examination of the patients to document how far advanced in puberty they were, measuring height of parents in order to document the genetic height potential, bone age x-rays of the hand to determine the growth potential at the time of admission to hospitalization, and laboratory tests. This design enabled us to validate the results of our first study so that our findings are now more scientifically grounded,” she said.  

“Our findings imply that in many cases there is a considerable delay in the diagnosis of anorexia nervosa, so that by the time of diagnosis significant growth delay has already occurred. Our findings also imply that damage caused by this delay in diagnosis was in part irreversible, even with intensive treatment,” Dr. Modan-Moses emphasized. On a clinical level, the results highlight the “importance of careful monitoring of height and weight by pediatricians, and early detection and early initiation of treatment of anorexia nervosa in adolescents with long-term efforts to improve and accelerate weight gain in order to prevent complications,” she said. “Research is needed to better define factors affecting catch-up growth (that is improved growth with correction of the height deficit observed at the time of admission) and to determine accordingly optimal treatment plans,” Dr. Modan-Moses added.

The study received no outside funding. The researchers had no financial conflicts to disclose.

The Food and Drug Administration has approved clascoterone 1% cream for the topical therapy of acne, providing a treatment with a novel mechanism of action for acne.

Clascoterone is a topical androgen receptor inhibitor indicated for treatment of acne vulgaris in patients aged 12 years and older, according to the labeling from manufacturer Cassiopea. Clascoterone, which will be marketed as Winlevi, targets the androgen hormones that contribute to acne by inhibiting serum production and inflammation, according to a company press release.

“Although clascoterone’s exact mechanism of action is unknown, laboratory studies suggest clascoterone competes with androgens, specifically dihydrotestosterone, for binding to the androgen receptors within the sebaceous gland and hair follicles,” according to the release.

Approval was based in part on a pair of phase 3, double-blind, vehicle-controlled, 12-week, randomized trials including 1,440 patients aged 9 years and older with moderate to severe facial acne. The findings were published in April, in JAMA Dermatology .

Participants were randomized to twice-daily application of clascoterone or a control vehicle; treatment success was defined as having an Investigator’s Global Assessment score of 0 (clear) or 1 (almost clear), as well as at least a 2-grade improvement from baseline, and absolute change in noninflammatory and inflammatory lesion counts at week 12.

At 12 weeks, treatment success rates were 18.4% and 20.3% among those on clascoterone, compared with 9% and 6.5%, respectively, among controls. There were also significant reductions in noninflammatory and inflammatory lesions from baseline at 12 weeks, compared with controls.

In the studies, treatment was well tolerated, with a safety profile similar to safety in controls. Adverse events thought to be related to clascoterone in the studies (a total of 13) included application-site pain; erythema; oropharyngeal pain; hypersensitivity, dryness, or hypertrichosis at the application site; eye irritation; headache; and hair color changes. “Clascoterone targets androgen receptors at the site of application and is quickly metabolized to an inactive form, thus limiting systemic activity,” the authors of the study wrote.

Clascoterone is expected to be available in the United States in early 2021, according to the manufacturer.
