A year into the COVID-19 pandemic, it is fair to say that children do transmit the virus, but at lower rates, Philip Zachariah, MD, of Columbia University, New York, said in a presentation at SHM Converge, the annual conference of the Society of Hospital Medicine.

Supportive care remains a key element in treating children with COVID-19, Dr. Zachariah emphasized. His presentation on pediatric hot topics in COVID-19 addressed several issues including the importance of risk stratification, current therapeutic options, and the latest on multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19.
 

Recognize the high-risk patient

When it comes to identifying risk factors for COVID-19 in children, remember that the trajectory of disease is diverse, Dr. Zachariah said.

The presentations of COVID-19 in children include those who are older and/or have comorbidities and present with mainly respiratory issues, those who are younger with symptoms that might overlap with Kawasaki disease, and those who are older with symptoms of cardiac involvement and MIS-C.

The overall hospitalization rate for children with COVID-19 is approximately 5%, but once hospitalized, the rates of ICU admission are approximately 30% and reflect rates seen in adult patients, Dr. Zachariah noted.

In general, data show that underlying conditions are more common in acute COVID-19 cases, and laboratory anomalies are more pronounced in patients with MIS-C, he said.

Based on the most recent studies, independent risk factors for acute COVID-19 in children include extremes of age (infancy or adolescence), minority populations, obesity, medical complexity, immune compromise, and asthma.

However, data are limited on specific issues of medical complexity, and risk depends on the level and type of immunosuppression, as morbidity and mortality have been relatively low in transplant patients, Dr. Zachariah noted.

Another dilemma lies in recognizing MIS-C in a febrile child, Dr. Zachariah noted. A complex question, “but persistent high fever in the setting of known recent COVID-19 infections (within 3 to 6 weeks) seems key,” he said. “If given the chance to do one blood test, I would suggest doing a CRP [C-reactive protein] as a screening test,” Dr. Zachariah said. The best laboratory prognosticators appear to be lymphopenia and brain natriuretic peptide (BNP) he added.

A final risk factor is innate immune defects that might predispose previously healthy children to severe acute COVID-19, such as differences in cytokine expression, said Dr. Zachariah.

“For example, autoantibodies against type 1 interferon production may dispose to severe disease,” he noted. Patients with MIS-C have shown patterns of T-cell activation similar to those seen in severely ill adults, and activation of vascular patrolling CX3CR1+ CD8 + T cells appears as a distinguishing feature in MIS-C, he explained.
 

Prevention plans with monoclonal antibodies

Another hot topic in pediatric COVID-19 is the prevention of severe disease and hospitalization using the currently available therapies, Dr. Zachariah said. However, when interpreting efficacy data, clinicians are almost always extrapolating relative risk to absolute risk in children, he noted.

“Convalescent plasma was promising, but the data on efficacy are increasingly negative,” he noted. Instead, a more exciting development is the use of monoclonal antibodies, which, ideally, “will deliver protection to ‘high risk’ populations in the very early stages of infection,” he said.

Bamlanivimab/etesevimab is “a neutralizing IgG1 monoclonal antibody that binds to overlapping domains of the receptor binding domain of the spike protein of SARS-CoV-2,” said Dr. Zachariah. In a study of 1,035 patients with a median age of 56 years, a single intravenous infusion of bamlanivimab plus etesevimab within 3 days of a positive COVID-19 test showed a 70% reduction in risk of COVID-19 hospitalizations or death.

For children, the current Food and Drug Administration Emergency Use Authorization for monoclonal antibody use covers patients aged 12-17 years, who weigh 40 kg or more, and meet any of several other criteria: a body mass index at the 85th percentile or higher, sickle cell disease, congenital or acquired heart disease, neurodevelopmental disorders such as cerebral palsy, chronic respiratory disease requiring daily control, diabetes, or chronic kidney disease, Dr. Zachariah said.

In addition, pediatric patients aged 12-17 years could be considered for monoclonal antibody treatment in consultation with a pediatric infectious disease specialist if they are symptomatic with COVID-19, weigh at least 40 kg, are not hospitalized for COVID-19 symptoms, and have no new oxygen requirements, he said.
 

More on MIS-C

Currently, IVIG is the most common treatment for MIS-C in the United States, Dr. Zachariah said. In addition, a study published in JAMA Feb. 1, 2021, showed that IVIG in combination with methylprednisolone was associated with a lower risk of treatment failure compared to IVIG alone in 111 children with a median age of 8.6 years.

Although comparative effectiveness data are lacking, in long-term follow-up, all the patients seemed to be doing fine, Dr. Zachariah said. Potential second-line therapies for atypical MIS-C include anakinra and tocilizumab, he added.

Dr. Zachariah concluded by emphasizing the potential of COVID-19 vaccines, with studies underway for both Moderna and Pfizer vaccines in children younger than 16 years.

Dr. Zachariah had no relevant financial conflicts to disclose.

As the COVID-19 pandemic continues and evidence evolves, clinical judgment is the bottom line for clinical care, according to Adarsh Bhimraj, MD, of the Cleveland Clinic, and James Walter, MD, of Northwestern Medicine, Chicago.

In a debate/discussion presented at SHM Converge, the annual conference of the Society of Hospital Medicine, Dr. Bhimraj and Dr. Walter took sides in a friendly debate on the value of remdesivir and tocilizumab for hospitalized COVID-19 patients.

Dr. Bhimraj argued for the use of remdesivir or tocilizumab in patients hospitalized with COVID-19 pneumonia, and Dr. Walter presented the case against their use.
 

Referendum on remdesivir

The main sources referenced by the presenters regarding remdesivir were the WHO Solidarity Trial (N Engl J Med. 2021 Feb 11. doi: 10.1056/NEJMoa2023184) and the Adaptive Covid-19 Treatment Trial (ACCT) final report (N Engl J Med. 2020 Nov 5. doi: 10.1056/NEJMoa2007764).

“The ‘debate’ is partly artificial,” and meant to illustrate how clinicians can use their own clinical faculties and reasoning to make an informed decision when treating COVID-19 patients, Dr. Bhimraj said.

The ACCT trial compared remdesivir with placebo in patients with severe enough COVID-19 to require supplemental oxygen, mechanical ventilation, or extracorporeal membrane oxygenation. The primary outcome in the study was time to recovery, and “the devil is in the details,” Dr. Bhimraj said. The outcomes clinicians should look for in studies are those that matter to patients, such as death, disability, and discomfort, he noted. Disease-oriented endpoints are easier to measure, but not always meaningful for patients, he said. The study showed an average 5-day decrease in illness, “but the fact is that it did not show a mortality benefit,” he noted.

Another large, open-label study of remdesivir across 30 countries showed no survival benefit associated with the drug, compared with standard of care, said Dr. Bhimraj. Patients treated with remdesivir remained in the hospital longer, but Dr. Bhimraj said he believed that was a bias. “I think the physicians kept the patients in the hospital longer to give the treatment rather than the treatments themselves prolonging the treatment duration,” he said.

In conclusion for remdesivir, “the solid data show that there is an early recovery,” he said. “At least for severe disease, even if there is no mortality benefit, there is a role. I argue that, if someone asks if you want to use remdesivir in severe COVID-19 patients, say yes, especially if you value people getting out of the hospital sooner. In a crisis situation, there is a role for remdesivir.”

Dr. Walter discussed the “con” side of using remdesivir. “We can start with a predata hypothesis, but integrate new data about the efficacy into a postdata hypothesis,” he said.

Dr. Walter made several points against the use of remdesivir in hospitalized COVID-19 patients. First, it has not shown any improvement in mortality and may increase the length of hospital stay, he noted.

Data from the ACCT-1 trial and the WHO solidarity trial, showed “no signal of mortality benefit at all,” he said. In addition, the World Health Organization, American College of Physicians, and National Institutes of Health all recommend against remdesivir for patients who require mechanical ventilation or extracorporeal membrane oxygenation, he said. The efficacy when used with steroids remains unclear, and long-term safety data are lacking, he added.
 

Taking on tocilizumab

Tocilizumab, an anti-inflammatory agent, has demonstrated an impact on several surrogate markers, notably C-reactive protein, temperature, and oxygenation. Dr. Bhimraj said. He reviewed data from eight published studies on the use of tocilizumab in COVID-19 patients.

Arguably, some trials may not have been powered adequately, and in combination, some trials show an effect on clinical deterioration, if not a mortality benefit, he said.

Consequently, in the context of COVID-19, tocilizumab “should be used early in the disease process, especially if steroids are not working,” said Dr. Bhimraj. Despite the limited evidence, “there is a niche population where this might be beneficial,” he said.

By contrast, Dr. Walter took the position of skepticism about the value of tocilizumab for COVID-19 patients.

Notably, decades of research show that tocilizumab has shown no benefit in patients with sepsis or septic shock, or those with acute respiratory distress syndrome, which have similarities to COVID-19 (JAMA. 2020 Sep 3. doi: 10.1001/jama.2020.17052).

He cited a research letter published in JAMA in September 2020, which showed that cytokine levels were in fact lower in critically ill patients with COVID-19, compared with those who had conditions including sepsis with and without ARDS.

Dr. Walter also cited data on the questionable benefit of tocilizumab when used with steroids and the negligible impact on mortality in hospitalized COVID-19 patients seen in the RECOVERY trial.

Limited data mean that therapeutic decisions related to COVID-19 are more nuanced, but they can be made, the presenters agreed.

Ultimately, when trying to decide whether a drug is efficacious, futile, or harmful, “What we have to do is consider the grand totality of the evidence,” Dr. Bhimraj emphasized.

Dr. Bhimraj and Dr. Walter had no relevant financial conflicts to disclose.

Teens with persistent nocturnal asthma symptoms were significantly more likely than were those without nighttime asthma to report poor functional health independent of daytime asthma, based on data from 430 adolescents aged 12-16 years.

Approximately half of children with severe asthma experience at least one night of inadequate sleep per week, and lost sleep among young children with asthma has been associated with impaired physical function, school absence, and worsened mood. However, the effect of asthma-related sleep disruption on daily function in teenagers in particular has not been well studied, according to Anne Zhang of the University of Rochester (N.Y.) and colleagues.

In a poster presented at the virtual meeting of the Pediatric Academic Societies (#542), the researchers reviewed baseline survey data from the School-Based Asthma Care for Teens (SB-ACT) study, a randomized, controlled trial conducted from 2014 to 2018 in Rochester, N.Y.

The average age of the respondents was 13.4 years, 56% were male, 56% were African American, 32% were Hispanic, and 84% had Medicaid insurance.

Persistent nocturnal asthma was defined as 2 or more nights of nighttime awakening in the past 14 days, and intermittent nocturnal asthma was defined as less than 2 nights of nighttime awakening in the past 14 days.

Overall, teens with persistent nocturnal asthma were significantly more likely than were those with intermittent nocturnal asthma to report physical limitations during strenuous activity (58% vs. 41%), moderate activity (32% vs. 19%), and school gym classes (36% vs. 19%; P <.01 for all).

In addition to physical impact, teens with persistent nocturnal asthma were more likely than were those with intermittent nocturnal asthma to report depressive symptoms (41% vs. 23%), asthma-related school absences in the past 14 days (0.81 vs. 0.12), and poorer quality of life (4.6 vs. 5.9, P <.01 for all).

The results remained significant in a multivariate analysis that controlled for daytime asthma symptoms, weight status, race, ethnicity, gender, age, and smoke exposure, the researchers said.

The study findings were limited by several factors including the cross-sectional design, potential of recall bias in survey responses, and lack of data on sleep duration and quality, the researchers noted.

However, the results suggest that improving nighttime asthma control for teens may improve daily function, and providers should ask teens with asthma about the possible effect and burden of nighttime symptoms, they said. Potential strategies to improve persistent nocturnal asthma symptoms include adjusting the timing of medications or physical activity, they added.

“We know that getting adequate, high-quality sleep is important for health - especially for adolescents,” said Kelly A. Curran, MD, of the University of Oklahoma Health Sciences Center, in an interview. “Just like adults, tired teens are not able to function at their best and are at higher risk of developing mood problems,” she said.

However, “There are already so many barriers for teens getting good sleep, such as screen time/social media, homework, busy social calendars, caffeine use, and early morning school start times,” she said. Underlying medical conditions such as depression, anxiety, and obstructive sleep apnea also can contribute to poor sleep for teens, she added.

“In my practice, I frequently counsel about sleep hygiene because it is so essential and not commonly followed,” said Dr. Curran. “Nocturnal asthma is another contributor to poor sleep - not one that I have been regularly screening for - and something we can potentially intervene in to help improve health and quality of life,” she emphasized.

Dr. Curran said that she was not surprised by the study findings, given what is known about the importance of sleep. In clinical practice, “Teens who have asthma should be screened for nocturnal symptoms as these are linked to worsened quality of life, including limitations in activities, depressive symptoms, and asthma-related school absence,” she said.

However, additional research is needed to better understand whether improving nocturnal asthma symptoms can help improve quality of life and daily functioning in adolescents, she noted.

Teens with persistent nocturnal asthma symptoms were significantly more likely than were those without nighttime asthma to report poor functional health independent of daytime asthma, based on data from 430 adolescents aged 12-16 years.

Approximately half of children with severe asthma experience at least one night of inadequate sleep per week, and lost sleep among young children with asthma has been associated with impaired physical function, school absence, and worsened mood. However, the effect of asthma-related sleep disruption on daily function in teenagers in particular has not been well studied, according to Anne Zhang of the University of Rochester (N.Y.) and colleagues.

In a poster presented at the virtual meeting of the Pediatric Academic Societies (#542), the researchers reviewed baseline survey data from the School-Based Asthma Care for Teens (SB-ACT) study, a randomized, controlled trial conducted from 2014 to 2018 in Rochester, N.Y.

The average age of the respondents was 13.4 years, 56% were male, 56% were African American, 32% were Hispanic, and 84% had Medicaid insurance.

Persistent nocturnal asthma was defined as 2 or more nights of nighttime awakening in the past 14 days, and intermittent nocturnal asthma was defined as less than 2 nights of nighttime awakening in the past 14 days.

Overall, teens with persistent nocturnal asthma were significantly more likely than were those with intermittent nocturnal asthma to report physical limitations during strenuous activity (58% vs. 41%), moderate activity (32% vs. 19%), and school gym classes (36% vs. 19%; P <.01 for all).

In addition to physical impact, teens with persistent nocturnal asthma were more likely than were those with intermittent nocturnal asthma to report depressive symptoms (41% vs. 23%), asthma-related school absences in the past 14 days (0.81 vs. 0.12), and poorer quality of life (4.6 vs. 5.9, P <.01 for all).

The results remained significant in a multivariate analysis that controlled for daytime asthma symptoms, weight status, race, ethnicity, gender, age, and smoke exposure, the researchers said.

The study findings were limited by several factors including the cross-sectional design, potential of recall bias in survey responses, and lack of data on sleep duration and quality, the researchers noted.

Barrett’s esophagus occurred in nearly 12% of patients who underwent esophagogastroduodenoscopy after sleeve gastrectomy, but it was not associated with postoperative gastroesophageal reflux disease (GERD), based on data from 10 studies that totaled 680 adult patients.

ChrisPole/thinkstock

Sleeve gastrectomy has become more popular in recent years as an effective strategy for patients with severe obesity, wrote Bashar J. Qumseya, MD, of the University of Florida, Gainesville, and colleagues. However, GERD is a common concern for patients undergoing sleeve gastrectomy and is the major risk factor for Barrett’s esophagus. However, the prevalence of Barrett’s esophagus in the sleeve gastrectomy population has not been examined.

In a meta-analysis published in Gastrointestinal Endoscopy, the researchers reviewed 10 studies that totaled 680 patients who underwent esophagogastroduodenoscopy 6 months to 10 years after a sleeve gastrectomy procedure. The primary outcome was Barrett’s esophagus prevalence in sleeve gastrectomy patients, with the prevalence of erosive esophagitis and GERD at follow-up as secondary outcomes.

Overall, 54 patients developed Barrett’s esophagus, for a pooled prevalence of 11.6%, and all cases were nondysplastic and de novo. There was no significant association between Barrett’s esophagus and the presence of postoperative GERD, the researchers said (odds ratio, 1.74; P = .37).

However, the rate of erosive esophagitis increased by 86% in five studies with long-term follow-up and by 35% in two studies with short-term follow-up, which suggests an increased risk of 13% each year after sleeve gastrectomy, the researchers noted.

Besides the risk of Barrett’s esophagus after sleeve gastrectomy, “the risk of [erosive esophagitis] is also of significant interest and shares the same pathophysiology with [Barrett’s esophagus] and GERD,” they emphasized.

The study findings were limited by several factors including the small sample size and the focus on Barrett’s esophagus rather than erosive esophagitis or GERD as the primary outcome, the researchers noted. However, the results indicate that sleeve gastrectomy patients are at increased risk for Barrett’s esophagus, and larger studies are needed to better understand the pathophysiology. Furthermore, although there is some debate regarding the risk of GERD and erosive esophagitis after sleeve gastrectomy, the authors wrote that the data from their study showed a “consistent and substantial trend” toward more erosive esophagitis after sleeve gastrectomy.

“Gastroenterologists, primary care providers, and bariatric surgeons should be aware” of the data and should discuss the risks of sleeve gastrectomy with patients before the procedure, including the risks and benefits of postprocedure screening for Barrett’s esophagus, they concluded.
 

Consider surveillance for Barrett’s

The study is important because of the increased rates of GERD and potentially Barrett’s esophagus that have been noted after sleeve gastrectomy, Gyanprakash A. Ketwaroo, MD, of Baylor College of Medicine, Houston, said in an interview.

“Many of these studies have been small, and the findings of meta-analyses have been limited by high heterogeneity,” he noted. “With the rise in popularity of sleeve gastrectomy, it is important to accurately assess potential long-term complications.”

Dr. Ketwaroo said he was not surprised by the study findings given several reports of increased GERD after sleeve gastrectomy. “Given the accepted pathophysiology of Barrett’s esophagus, I anticipated increased risk of Barrett’s esophagus after sleeve gastrectomy as well.

“Clinicians should consider surveillance for Barrett’s esophagus after sleeve gastrectomy, and possible early proton pump inhibitor use for both GERD/erosive esophagitis and Barrett’s esophagus chemoprophylaxis. Patients with longer-segment or dysplastic Barrett’s esophagus prior to sleeve gastrectomy may have to be monitored more closely after surgery,” he said.

Dr. Ketwaroo noted that the study was limited by the small sample size, “with only approximately 50 patients with Barrett’s esophagus after surgery among 680 overall.” He emphasized that “we will need a much larger prospective study to confirm this finding. Additionally, I would want to explore if sleeve gastrectomy increases rate of progression of dysplasia in those who develop Barrett’s esophagus.”

The study received no outside funding. Lead author Dr. Qumseya had no financial conflicts to disclose. Dr. Ketwaroo serves on the GI & Hepatology News editorial advisory board.

Besides the risk of Barrett’s esophagus after sleeve gastrectomy, “the risk of [erosive esophagitis] is also of significant interest and shares the same pathophysiology with [Barrett’s esophagus] and GERD,” they emphasized.

The study findings were limited by several factors including the small sample size and the focus on Barrett’s esophagus rather than erosive esophagitis or GERD as the primary outcome, the researchers noted. However, the results indicate that sleeve gastrectomy patients are at increased risk for Barrett’s esophagus, and larger studies are needed to better understand the pathophysiology. Furthermore, although there is some debate regarding the risk of GERD and erosive esophagitis after sleeve gastrectomy, the authors wrote that the data from their study showed a “consistent and substantial trend” toward more erosive esophagitis after sleeve gastrectomy.

“Gastroenterologists, primary care providers, and bariatric surgeons should be aware” of the data and should discuss the risks of sleeve gastrectomy with patients before the procedure, including the risks and benefits of postprocedure screening for Barrett’s esophagus, they concluded.
 

Consider surveillance for Barrett’s

The study is important because of the increased rates of GERD and potentially Barrett’s esophagus that have been noted after sleeve gastrectomy, Gyanprakash A. Ketwaroo, MD, of Baylor College of Medicine, Houston, said in an interview.

“Many of these studies have been small, and the findings of meta-analyses have been limited by high heterogeneity,” he noted. “With the rise in popularity of sleeve gastrectomy, it is important to accurately assess potential long-term complications.”

Dr. Ketwaroo said he was not surprised by the study findings given several reports of increased GERD after sleeve gastrectomy. “Given the accepted pathophysiology of Barrett’s esophagus, I anticipated increased risk of Barrett’s esophagus after sleeve gastrectomy as well.

“Clinicians should consider surveillance for Barrett’s esophagus after sleeve gastrectomy, and possible early proton pump inhibitor use for both GERD/erosive esophagitis and Barrett’s esophagus chemoprophylaxis. Patients with longer-segment or dysplastic Barrett’s esophagus prior to sleeve gastrectomy may have to be monitored more closely after surgery,” he said.

Dr. Ketwaroo noted that the study was limited by the small sample size, “with only approximately 50 patients with Barrett’s esophagus after surgery among 680 overall.” He emphasized that “we will need a much larger prospective study to confirm this finding. Additionally, I would want to explore if sleeve gastrectomy increases rate of progression of dysplasia in those who develop Barrett’s esophagus.”

The study received no outside funding. Lead author Dr. Qumseya had no financial conflicts to disclose. Dr. Ketwaroo serves on the GI & Hepatology News editorial advisory board.

Hospitalized patients with acute respiratory failure can benefit from high-flow nasal oxygen in certain settings, according to a new clinical guideline from the American College of Physicians.

High-flow nasal oxygen (HFNO) has demonstrated advantages including improved oxygenation and ventilation, wrote Arianne K. Baldomero, MD, of Minneapolis Veterans Affairs Health Care System and the University of Minnesota, Minneapolis, and colleagues. “However, the comparative benefits and harms of HFNO in clinical outcomes, including mortality, intubation, hospital length of stay, patient comfort, clearance of airway secretions, and reduced work of breathing are not well known.”

In the guideline, published in Annals of Internal Medicine, the authors recommend the use of high-flow nasal oxygen in hospitalized patients for initial or postextubation management of acute respiratory failure. The target population includes those patients treated in hospital wards, EDs, intermediate/step-down units, and ICUs.

Use of HFNO therapy as a form of noninvasive respiratory support for hospitalized patients has increased in recent years. The treatment involves delivering warm, humidified oxygen via nasal cannula at a flow level higher than the patient’s inspiratory flow.

Potential benefits of HFNO include greater patient comfort, improved compliance, and psychological benefits, according to the authors. HFNO also can be used as respiratory support in critically ill patients for a number of indications including respiratory failure or support post extubation; however, treatment of patients with COVID-19 and related conditions were not considered in the guideline.

The guideline was based on evidence comparing HFNO with conventional oxygen therapy (COT) and noninvasive ventilation (NIV). The authors reviewed 29 randomized, controlled trials that showed clinically meaningful outcomes in HFNO patients, as well as similar rates of, or reductions in, mortality, intubations, and hospital-acquired pneumonia, and increased reports of patient comfort. Data also supported the safety of HFNO with few, if any, contraindications other than problems with fitting the nasal cannula.

Across several trials comparing HFNO and NIV for initial management of acute respiratory failure, HFNO reduced all-cause mortality, intubation, and hospital-acquired pneumonia, although the authors categorized the results as “low-certainty evidence.” HFNO was not more effective than NIV for postextubation management. Based trials comparing HFNO and COT for postextubation management, the authors concluded that HFNO may reduce rates of reintubation and improve patient comfort, also with low-certainty evidence.

The research was limited by a lack of studies comparing HFNO with NIV or COT for acute respiratory failure in patients who were post lung transplantation, or for those with pulmonary embolism, pulmonary arterial hypertension, or asthma, the authors said. Other limitations included the variation in study design, study populations, and treatment protocols across the included studies. Additional research is needed to better identify the patients most likely to benefit from HFNO, according to type of acute respiratory failure.

Despite these limitations, the results support the guideline recommendation for HFNO in cases of acute respiratory failure and postextubation management. However, “broad applicability, including required clinician and health system experience and resource use, remains unknown,” the authors concluded.

Research catches up with practice

The guidelines are important at this time because “the medical literature over the past 3-4 years is catching up to what hospitalists, pulmonologists, and critical care specialists have been doing clinically over the past 6-8 years with perceived better results, Jacqueline W. Fincher, MD, MACP, President of the American College of Physicians, said in an interview.

“HFNO has been used to a varying degree over the last 6-8 years by physicians with much-perceived improved benefit in patients who are hypoxemic on usual noninvasive therapy or conventional oxygen therapy with the impending need for intubation or post extubation,” Dr. Fincher said. “During the COVID pandemic particularly with the attack on the respiratory system with COVID pneumonia and frequently associated ARDS [acute respiratory distress syndrome], the use of HFNO has been enormously helpful in trying to keep patients well oxygenated without having to intubate or reintubate them.

“We now have the medical literature that supports what has been seen clinically to make the recommendations and guidelines based on the scientific evidence,” Dr. Fincher added. “If we can avoid intubation associated with the patient being sedated, unable to eat, talk, or meaningfully participate in their care or get the patient off the ventilator sooner for the same reasons, then we have significantly improved the quality of their care, decreased their risk of infection, decreased their days in the ICU and the hospital, we will have succeeded in providing the best care possible. The availability of HFNO, with much greater comfort to the patient than being intubated, is a great tool in the toolbox of respiratory care.”

Dr. Fincher said she was not surprised by any of the recommendations. “We knew the use of HFNO helped but we were surprised by the evidence of the degree to which it is enormously helpful to patients.

“The good news is that HFNO is readily available at most hospitals, but it really requires an intensive care unit and a team of physicians, nurses, and respiratory therapists to be familiar with its use and work closely together to monitor the patient for significant changes in their respiratory status to titrate therapy,” she noted.

Looking ahead, some areas in need of more research that might impact updates to the guidelines include “What are some areas in need of more research that might impact future updates to these guidelines? Specifics on whether initiating HFNO earlier in the course of the patient’s hypoxemic illness is better or worse, as well as the use of HFNO outside of the ICU setting,” Dr. Fincher said. “The needed monitoring of the patient to know whether their respiratory status was deteriorating and how fast would be critical along with the specific indications for titration of the HFNO.”

The evidence review was commissioned and funded by the ACP. The data come from work supported by and conducted at the Minneapolis VA Health Care System. Lead author Dr. Baldomero was supported in part by the National Institutes of Health National Center for Advancing Translational Sciences.

Hispanic diabetes patients are significantly less likely than Black or White patients to receive preventive guideline-based care soon after diagnosis, based on data from more than 7,000 individuals.

Racial and ethnic disparities in diabetes care remain a pervasive health problem, and minorities including non-Hispanic Blacks and Hispanics experience higher rates of complications, including retinopathy and neuropathy, compared with other groups, Felippe Ottoni Marcondes, MD, of Massachusetts General Hospital, Boston, and colleagues noted in a poster presented at the annual meeting of the Society for General Internal Medicine.

Data from previous studies have shown that diabetes patients who receive guideline-directed preventive care soon after diagnosis can reduce their risk of complications, they said.

To identify disparities in the provision of guideline-directed preventive care, the researchers analyzed data from 7,341 individuals who participated in the National Health Interview Survey from 2011 to 2017. They reviewed associations between race/ethnicity and visits to an eye specialist, a foot specialist, and checks of blood pressure and cholesterol in the past year among individuals diagnosed with diabetes within the past 5 years.

Overall, Hispanics had significantly lower rates of insurance coverage (75.9%), compared with non-Hispanic Whites (93.2%) and non-Hispanic Blacks (88.1%; P < .001).

Hispanics also were significantly less likely than Whites to have had a prior year eye exam (odds ratio, 0.80) and blood pressure check (OR, 0.45), after controlling for variables including age, sex, socioeconomic status, health insurance, general health status, U.S. region, marital status, body mass index, and various comorbidities.

Although insurance coverage mediated 42.8% of the total effect of race/ethnicity on annual eye specialist visits for Hispanics as compared with Whites, there was no significant effect for Blacks, compared with Whites.
 

COVID concerns impact diabetes disparities

“As the diabetes epidemic continues in the U.S., it is important to bring to the front of the diabetes care conversation racial/ethnic disparities that persisted or have been only partially addressed,” Dr. Marcondes said in an interview. “It is also important to emphasize that patients with diabetes are at higher risk for COVID-19 hospitalizations, complications, and death, and COVID-19 has disproportionately affected racial/ethnic minorities, so racial/ethnic minorities with diabetes have compounded risk of complications not only from diabetes but also from COVID-19.

“Importantly, our study highlights disparities in health care that are likely the product of systemic inequalities in access to care and insurance coverage at a moment when conversations about the race/racism and their health impact are fresh in the minds of public and health policy officials and the general public,” he emphasized.

“Unfortunately, I cannot say that I am surprised by our findings,” Dr. Marcondes said. “We expected to see some differences in the receipt of care for racial/ethnic minorities compared to white individuals for those recently diagnosed with diabetes, and that is exactly what our findings show.”

However, “what was perhaps intriguing is that disparities in the receipt of guideline-directed care were greater for Hispanic compared to White individuals than for Black compared to White individuals,” said Dr. Marcondes. “The causes of these differences are many. Hispanic individuals are less likely than White and Black persons to have insurance coverage.” Other unmeasured factors include language barriers that Hispanic individuals may face, as well as the bias and discrimination experienced by Hispanic and Black individuals alike.
 

Focus on equitable early intervention

“There is plenty of evidence in the medical literature that Black and Hispanic individuals with diabetes, as well as other minorities, have higher risk of complications of diabetes such as retinopathy, nephropathy, as well as cardiovascular risk factors such as high blood pressure and cholesterol,” Dr. Marcondes said. “Yet, complications in the time that immediately follows the diagnosis of diabetes are likely to be low.”

To reduce the risk of complications in the future, “physicians and health providers need to focus on providing equitable, guideline-directed treatment for their minority patients recently diagnosed with diabetes,” Dr. Marcondes emphasized. “Intervening early in the disease course will hopefully lead to a decrease in the rate of complications for racial/ethnic minorities. Clinicians, especially primary care physicians and providers, need to be aware that they are often the first encounter of many patients with the health care system. Effective communication and unbiased language on the part of clinicians will lead to stronger patient-physician relationships that foster opportunity to discuss disease prevention.

“Additional research is needed to evaluate the attitudes and biases of primary care providers and access the impact of patient navigation resources when treating minority patients with diabetes,” he concluded.

Digging Deeper into Disparities
“In diabetes, there are known racial and ethnic disparities such that minorities receive suboptimal screening and treatment, and have worse outcomes,” said Scott J. Pilla, MD, of The Johns Hopkins University School of Medicine, Baltimore, in an interview. 

“This study examines disparities in diabetes preventive measures in the U.S. using a national survey (NHIS) over the past decade. They took the important step of stratifying their analyses by health insurance and socioeconomic status which, in addition to race, may have a large impact,” said Dr. Pilla. However, “One critique of the poster is that it is unclear whether the researchers weighted their analyses to account for the nationally representative sampling of the NHIS survey,” he noted. 
Dr. Pilla said the finding that Hispanic patients had fewer diabetes preventive measures lines up with previous research in this area. 

“I was surprised that the disparities did not extend to black patients, who have been found to also receive suboptimal care compared to white patients in other studies,” he noted. 

The message for clinical practice: “Minorities with diabetes are at a higher risk of adverse diabetes outcomes and may need extra support and resources to achieve their evidence-based diabetes prevention,” Dr. Pilla said. 

“More research is needed to understand the root cause of racial and ethnic disparities in diabetes management to tease apart possible contributors including health insurance coverage, socioeconomic factors, cultural and community factors, and systemic racism. This will help inform targeted approaches to reducing disparities in diabetes care,” he emphasized.

The researchers had no relevant financial conflicts to disclose. Dr. Pilla had no financial conflicts to disclose.

Hispanic individuals are less likely than White and Black persons to have insurance coverage.” Other unmeasured factors include language barriers that Hispanic individuals may face, as well as the bias and discrimination experienced by Hispanic and Black individuals alike.
 

Focus on equitable early intervention

“There is plenty of evidence in the medical literature that Black and Hispanic individuals with diabetes, as well as other minorities, have higher risk of complications of diabetes such as retinopathy, nephropathy, as well as cardiovascular risk factors such as high blood pressure and cholesterol,” Dr. Marcondes said. “Yet, complications in the time that immediately follows the diagnosis of diabetes are likely to be low.”

To reduce the risk of complications in the future, “physicians and health providers need to focus on providing equitable, guideline-directed treatment for their minority patients recently diagnosed with diabetes,” Dr. Marcondes emphasized. “Intervening early in the disease course will hopefully lead to a decrease in the rate of complications for racial/ethnic minorities. Clinicians, especially primary care physicians and providers, need to be aware that they are often the first encounter of many patients with the health care system. Effective communication and unbiased language on the part of clinicians will lead to stronger patient-physician relationships that foster opportunity to discuss disease prevention.

“Additional research is needed to evaluate the attitudes and biases of primary care providers and access the impact of patient navigation resources when treating minority patients with diabetes,” he concluded.

Digging Deeper into Disparities
“In diabetes, there are known racial and ethnic disparities such that minorities receive suboptimal screening and treatment, and have worse outcomes,” said Scott J. Pilla, MD, of The Johns Hopkins University School of Medicine, Baltimore, in an interview. 

“This study examines disparities in diabetes preventive measures in the U.S. using a national survey (NHIS) over the past decade. They took the important step of stratifying their analyses by health insurance and socioeconomic status which, in addition to race, may have a large impact,” said Dr. Pilla. However, “One critique of the poster is that it is unclear whether the researchers weighted their analyses to account for the nationally representative sampling of the NHIS survey,” he noted. 
Dr. Pilla said the finding that Hispanic patients had fewer diabetes preventive measures lines up with previous research in this area. 

“I was surprised that the disparities did not extend to black patients, who have been found to also receive suboptimal care compared to white patients in other studies,” he noted. 

The message for clinical practice: “Minorities with diabetes are at a higher risk of adverse diabetes outcomes and may need extra support and resources to achieve their evidence-based diabetes prevention,” Dr. Pilla said. 

“More research is needed to understand the root cause of racial and ethnic disparities in diabetes management to tease apart possible contributors including health insurance coverage, socioeconomic factors, cultural and community factors, and systemic racism. This will help inform targeted approaches to reducing disparities in diabetes care,” he emphasized.

The researchers had no relevant financial conflicts to disclose. Dr. Pilla had no financial conflicts to disclose. 

The Food and Drug Administration has approved a new estrogen for the first time in more than 50 years.

The novel combined oral contraceptive, marketed as Nextstellis, contains 3 mg drospirenone (DRSP) and 14.2 mg of estetrol (E4) in tablet form. Estetrol is an estrogen that is naturally produced during pregnancy, but will now be produced from a plant source; it has not previously been used in oral contraceptives.

Approval of the unique estetrol/drospirenone combination was based on data from a pair of phase 3 clinical trials including 3,725 women. Overall, Nextstellis was safe and effective while meeting its primary endpoint of pregnancy prevention, according to a company press release. Participants also reported favorable results on secondary endpoints including cycle control, bleeding profile, safety, and tolerability.

Although many women take short-acting contraceptives containing estrogen and progestin, concerns persist about side effects, said Mitchell Creinin, MD, of the University of California, in the press release. In addition to providing effective contraception, the drug showed minimal impact on specific markers of concern, including triglycerides, cholesterol, and glucose, as well as weight and endocrine markers, Dr. Creinin said.

Nextstellis was developed by the Belgian biotech company Mithra Pharmaceuticals, and the drug is licensed for distribution in Australia and the United States by Mayne Pharma, with an expected launch at the end of June 2021.

Schizophrenia patients with parkinsonism show unique neurodevelopmental signatures on imaging that involve the sensorimotor system, according to MRI data from 73 adult schizophrenia patients.

Although sensorimotor abnormalities are common in patients with schizophrenia, the neurobiology of parkinsonism in particular is not well understood. Aberrant neurodevelopment is considered a potential mechanism of action for the emergence of such abnormalities, wrote Robert Christian Wolf, MD, of Heidelberg (Germany) University, and colleagues.

In a multimodal MRI study published in Schizophrenia Research, the investigators identified 38 adults with schizophrenia and parkinsonism (SZ-P), 35 schizophrenia patients without parkinsonism (SZ-nonP), and 20 healthy controls.

Parkinsonism was defined as scores of 4 or higher on the Simpson-Angus Scale, while non-Parkinsonism schizophrenia patients had scores of 1 or less.

The researchers examined cortical and subcortical gray-matter volume, as well as three cortical surface markers related to neurodevelopment: cortical thickness (CTh), complexity of cortical folding (CCF), and sulcus depth.

Overall, the SZ-P patients showed increased CCF in the left supplementary motor cortex (SMC) and decreased left postcentral sulcus depth, compared with SZ-nonP patients (P < .05). The left SMC also showed increased CCF, compared with healthy controls – but that difference was not significant.

Both SZ-P and SZ-nonP patients showed higher levels of activity in the left SMC, compared with controls, and activity was higher in SZ-nonP patients, compared with SZ-P patients. In addition, parkinsonism severity was negatively associated with left middle frontal CCF and left anterior cingulate cortex CTh, Dr. Wolf and colleagues reported.

“Overall, the data support the notion that cortical features of distinct neurodevelopmental origin, particularly cortical folding indices such as CCF and sulcus depth, contribute to the pathogenesis of parkinsonism in SZ,” the researchers said.

The study findings were limited by several factors, including the cross-sectional design, the challenges of using the potential restraint inherent in the Simpson-Angus Scale to diagnose parkinsonism, the inability to gauge the impact of lifetime exposure to antipsychotics, and the inability to identify changes in brain stem nuclei, the researchers noted. However, the results suggest the impact of cortical development on parkinsonism in schizophrenia,.

“Cortical surface changes in the sensorimotor system suggest abnormal neurodevelopmental processes that are associated with increased risk for intrinsic sensorimotor abnormalities in SZ and related psychotic disorders,” they concluded.

The study was supported by the German Research Foundation and the German Federal Ministry of Education and Research. The researchers disclosed no financial conflicts.

Bipolar disorder patients with comorbid obsessive-compulsive disorder were significantly more likely to suffer from tic disorders, as well as hoarding, excoriation, and body dysmorphic disorder, than were those without comorbid OCD, data from 70 patients suggest.

Between 10% and 20% of patients with bipolar disorder (BD) also meet criteria for obsessive-compulsive disorder (OCD), and these patients are more likely to experience treatment resistance and poor prognosis than are BD patients without OCD. In addition, preliminary indications suggest a specific association between OCD and bipolar depression (BP-D) in particular, wrote Leonid Braverman, MD, of Ma’ale HaCarmel Mental Health Center, Tirat Carmel, Israel, and colleagues.

In addition, “there is compelling evidence indicating that OCD-spectrum and tic disorders share with OCD clinical characteristics, familial inheritance, neurobiological underpinnings and some aspects of pharmacotherapy,” and investigations into the clinical characteristics of OCD spectrum behaviors in BP-D patients with and without OCD are ongoing, they said.

In a study published in the Journal of Obsessive-Compulsive and Related Disorders (2021 Mar 21. doi: 10.1016/j.jocrd.2021.100643), the researchers reviewed data from 87 adults who met the DSM-5 criteria for BP-D. Of these, 27 also met criteria for OCD, 17 for subthreshold OCD, and 43 had neither OCD nor subthreshold OCD. The researchers compared the 27 OCD patients and the 43 non-OCD patients; the OCD patients had significantly higher rates overall of body dysmorphic disorder, hoarding disorder, excoriation disorder, and tic disorder, compared with non-OCD patients (P range from < .05-0.01 for all). No differences between the groups appeared for trichotillomania.

Also, the researchers found significant between-group differences in the number of patients with at least one OCD spectrum disorder and tic disorders (13 of 19 patients in the OCD group vs. 3 of 37 patients in the non-OCD group) and in the co-occurrence of two OCD-spectrum and tic disorders (3 of 19 patients in the OCD group vs. 1 patient in the non-OCD group).

The most common comorbid psychiatric disorders in both groups were substance use and combined anxiety disorders, followed by eating disorders, but no between-group differences were found in the frequencies of any of these conditions.

“From the clinical perspective, the finding of an aggregation of OCD-spectrum and tic disorders in BP-D/OCD patients justifies evaluation of these comorbidities in BP-D patients,” the researchers noted.

The study findings were limited by several factors, including the small sample size, cross-sectional design, and exclusion of subsyndromic disorders, the researchers noted. However, the results support findings from previous studies, and the study emphasizes the clinical complexity and poor prognosis for these patients. Therefore, additional research is needed in patients with BP-D verse the manic/hypomanic phases of bipolar illness to determine similar patterns, they said. Medication trials are needed to address functional impairments in these patients, given the differences in treatment of BDD, hoarding, excoriation, and tic disorders, compared with “pure” OCD, they concluded.

The study received no outside funding. The researchers reported no financial conflicts.
