Neurology Reviews

Patients with neuropsychiatric manifestations of systemic lupus erythematosus (NPSLE) seem to benefit from rituximab (Rituxan) therapy, according to data from the British Isles Lupus Assessment Group Biologics Register (BILAG-BR).

Indeed, the percentage of patients with active disease, as scored by the BILAG-2004 index or SLEDAI-2K (SLE Disease Activity Index 2000), fell significantly (P < .0001) when comparing pre- and postrituximab treatment scores. There was also a reduction in the dose of oral steroids used.

Interestingly, the use of concomitant cyclophosphamide might enhance the level of improvement seen in some patients, Trixy David, MBBS, reported during an abstract session at the British Society for Rheumatology annual conference.

“Larger-scale studies are warranted to establish the effectiveness of rituximab alone, or in combination with cyclophosphamide, in the treatment neuropsychiatric lupus,” said Dr. David, a clinical research fellow at the University of Manchester (England) and specialist registrar in rheumatology at the Manchester University National Health Service Foundation Trust.

Neil Basu, MBChB, PhD, who chaired the virtual session, called the findings “enlightening” and “descriptive.”

The study “provides some interesting data, which should be tested in a robust, randomized clinical trial,” he agreed, and not that clinicians should now start using rituximab for their NPSLE cases.

Dr. Basu, who is a clinical senior lecturer in rheumatology and honorary consultant rheumatologist at the Institute of Infection, Immunity and Inflammation at the University of Glasgow, added: “It is really important that we do these studies to help support a rationale for such a trial, which are obviously very expensive and require strong evidence before we go down that track. I think these data have really been quite enlightening in that respect.”

Rationale for rituximab in neuropsychiatric lupus

Managing patients with NPSLE remains an area of substantial unmet need. According to a recent review in Rheumatology, “there is a dearth of controlled clinical trials to guide management” and “therapeutic options include symptomatic, antithrombotic, and immunosuppressive agents that are supported by observational cohort studies.”

Despite being seen in at least half of all patients with SLE, neuropsychiatric disease “is not very well studied in patients with lupus, as a lot of large-scale trials tend to exclude patients with active neurological disease,” Dr. David said.

Although it is unclear why neuropsychiatric disease occurs in SLE, it could be “as a result of vascular injury or disruption of the blood brain barrier, thereby allowing the passive diffusion of autoantibodies and cytokines across through the cerebral spinal fluid, thereby generating a proinflammatory response,” Dr. David suggested.

“We know B cells are involved in the pathogenesis of lupus, and rituximab is a chimeric monoclonal antibody that selectively targets CD20-positive B cells and mediates transient B-cell depletion,” she said. Notably, there have been some small studies suggesting that rituximab may be effective in neuropsychiatric lupus, and it is currently widely used to treat refractory lupus in the United Kingdom.
 

About the BILAG-BR and results

“Our aim was to describe the baseline characteristics and short-term effectiveness of rituximab in patients treated for neuropsychiatric lupus within the BILAG-BR,” Dr. David explained.

Started in 2009, the BILAG-BR now contains information on more than 1,400 individuals with SLE who have been recruited at 62 centers in the United Kingdom. Its purpose is to evaluate the long-term safety and effectiveness of biologic drugs versus standard immunosuppressive therapy such as azathioprine, mycophenolate mofetil, cyclophosphamide, and cyclosporine. To date, 1,229 patients have been treated with biologics, of whom 1,056 have received rituximab.

A total of 74 rituximab-treated patients were identified as having active neuropsychiatric disease, making this “the largest prospective observational cohort to date, to our knowledge,” Dr. David said.

The median age of patients was 45.5 years, the majority was female (82%) and White (74%). The median disease duration was 11.5 years.

A total of 96% had multiple organ involvement and not just neuropsychiatric disease, and 91% were positive for antineutrophil antibodies.

The top six neuropsychiatric manifestations were cognitive dysfunction and lupus headache (both affecting 27.5% of patients); acute confessional state or mononeuropathy (each seen in 10% of patients); and seizure disorder and polyneuropathy, seen in a respective 8.6% and 8.7% of patients. These findings are in line with a 2011 meta-analysis, Dr. David pointed out.

BILAG-2004 scores before and after rituximab treatment were available for 50 patients. The number of patients with a BILAG A score dropped from 24 (48%) at baseline to 7 (14%) after treatment with rituximab, and the number with a BILAG B score declined from 26 (52%) at baseline to 4 (8%) after rituximab (both P < .0001).

There was also a reduction following rituximab treatment in the percentage of patients categorized as having mainly central nervous system disease (70% vs. 11%), peripheral nervous system disease (19% vs. 6%), or both (11% vs. 8%).

Total SLEDAI-2K scores were also reduced following rituximab treatment, from a median of 12 at baseline to 2 (P < .0001).

Pre- and postrituximab oral prednisolone doses were a median of 15 mg and 10 mg (P = .009).

Limitations

“Our data are from a real-world setting of patients who had active neuropsychiatric disease and were treated with rituximab,” Dr. David said. There are of course many limitations that go hand in hand with observational studies.

“There was the issue of missing data,” Dr. David said. It was difficult or not possible to determine what doses of steroids patients were taking after rituximab therapy, particularly in terms of intravenous steroids, and what doses of any other concomitant disease-modifying therapy might have been around the time that patients initiated or stopped rituximab treatment.

“These could have acted as potential confounders,” she acknowledged.

Dr. Basu noted: “My major haziness from it is the uncertainty of knowing why these patients improved. Yes, they had rituximab, but I’m sure also that they probably received high doses of steroids if they had quite severe CNS lupus which was categorized as a BILAG-A or a B.”

Patients may also be given methylprednisolone when clinicians are really concerned, he continued, and “as was quite clearly pointed out,” there was quite a lot of missing data from a steroid perspective.

Dr. David and coinvestigators reported having no conflicts of interest. The BILAG-BR is supported by funding from Lupus UK, GlaxoSmithKline, and Roche. Dr. Basu did not state having any disclosures.

The Centers for Disease Control and Prevention is finalizing new guidelines to help clinicians diagnose and manage long COVID, or postacute sequelae of SARS-CoV-2 infection.

In a day-long congressional hearing on April 28, John Brooks, MD, a medical epidemiologist at the CDC’s division of HIV/AIDS prevention, testified that the guidelines were going through the clearance process at the agency, but would be forthcoming.

“They should be coming out very shortly,” Dr. Brooks said.

The guidelines, which were developed in collaboration with newly established long-COVID clinics and patient advocacy groups, will “illustrate how to diagnose and begin to pull together what we know about management,” of the complex condition, he said.

For many doctors and patients who are struggling to understand symptoms that persist for months after the initial viral infection, the guidelines can’t come soon enough.

National Institutes of Health Director Francis Collins, MD, PhD, who also testified at the hearing, estimated that as many as 3 million people could be left with chronic health problems after even mild COVID infections.

“I can’t overstate how serious this issue is for the health of our nation,” he said.

Dr. Collins said his estimate was based on studies showing that roughly 10% of people who get COVID could be affected by this and whose “long-term course is uncertain,” he said. So far, more than 32 million Americans are known to have been infected with the new coronavirus.

“We need to make sure we put our arms around them and bring answers and care to them,” said Rep. Anna Eshoo (D-Calif.), chairwoman of the Subcommittee on Health.

Jennifer Possick, MD, who directs the post-COVID recovery program at Yale New Haven (Conn.) Hospital, testified that the tidal wave of patients she and her colleagues were seeing was overwhelming.

“We are a well-resourced program at an academic medical center, but we are swamped by the need in our community. This year, we have seen more patients with post COVID-19 conditions in our clinic alone than we have new cases of asthma and COPD combined,” she said. “The magnitude of the challenge is daunting.”

Dr. Possick estimated that there are “over 60” clinics in the United States that have started to treat long-COVID patients, but said they are grassroots efforts and all very different from each other.

“Whoever had the resources, had the time, [and] was able to take the initiative and forge to the relationships because most of them are multidisciplinary, did so,” she said.
 

Patients testify

Several representatives shared moving personal stories of loved ones or staffers who remained ill months after a COVID diagnosis.

Rep. Ann Kuster, from New Hampshire, talked about her 34-year-old niece, a member of the U.S. Ski Team, who had COVID just over a year ago and “continues to struggle with everything, even the simplest activities of daily living” she said. “She has to choose between taking a shower or making dinner. I’m so proud of her for hanging in there.”

Long-COVID patients invited to testify by the subcommittee described months of disability that left them with soaring medical bills and no ability to work to pay them.

“I am now a poor, Black, disabled woman, living with long COVID,” said Chimere Smith, who said she had been a school teacher in Baltimore. “Saying it aloud makes it no more easy to accept.”

She said COVID had affected her ability to think clearly and caused debilitating fatigue, which prevented her from working. She said she lost her vision for almost 5 months because doctors misdiagnosed a cataract caused by long COVID as dry eye.

“If I did not have a loving family, I [would] be speaking to you today [from] my car, the only property I now own.”

Ms. Smith said that long-COVID clinics, which are mostly housed within academic medical centers, were not going to be accessible for all long-haulers, who are disproportionately women of color. She has started a clinic, based out of her church, to help other patients from her community.

“No one wants to hear that long COVID has decimated my life or the lives of other black women in less than a year,” Ms. Smith said. “We’ve just been waiting and hoping for compassionate doctors and politicians who would acknowledge us.”

In a global meta-analysis of more than 7,000 patients who were hospitalized with COVID-19, individuals with overweight or obesity were more likely to need respiratory support but were not more likely to die in the hospital, compared to individuals of normal weight.
 

Compared to patients without diabetes, those with diabetes had higher odds of needing invasive respiratory support (with intubation) but not for needing noninvasive respiratory support or of dying in the hospital.

“Surprisingly,” among patients with diabetes, being overweight or having obesity did not further increase the odds of any of these outcomes, the researchers wrote. The finding needs to be confirmed in larger studies, they said, because the sample sizes in these subanalyses were small and the confidence intervals were large.

The study by Danielle K. Longmore, PhD, of Murdoch Children’s Research Institute (MCRI), Melbourne, and colleagues from the International BMI-COVID consortium, was published online April 15 in Diabetes Care.

This new research “adds to the known data on the associations between obesity and severe COVID-19 disease and extends these findings” to patients who are overweight and/or have diabetes, Dr. Longmore, a pediatric endocrinologist with a clinical and research interest in childhood and youth obesity, said in an interview.

Immunologist Siroon Bekkering, PhD, of Radboud University Medical Center, Nijmegen, the Netherlands, explained that never before have so much data of different types regarding obesity been combined in one large study. Dr. Bekkering is a coauthor of the article and was a principal investigator.

“Several national and international observations already showed the important role of overweight and obesity in a more severe COVID-19 course. This study adds to those observations by combining data from several countries with the possibility to look at the risk factors separately,” she said in a statement from her institution.

“Regardless of other risk factors (such as heart disease or diabetes), we now see that too high a BMI [body mass index] can actually lead to a more severe course in [coronavirus] infection,” she said.
 

Study implications: Data show that overweight, obesity add to risk

These latest findings highlight the urgent need to develop public health policies to address socioeconomic and psychological drivers of obesity, Dr. Longmore said.

“Although taking steps to address obesity in the short term is unlikely to have an immediate impact in the COVID-19 pandemic, it will likely reduce the disease burden in future viral pandemics and reduce risks of complications like heart disease and stroke,” she observed in a statement issued by MCRI.

Coauthor Kirsty R. Short, PhD, a research fellow at the University of Queensland, Brisbane, Australia, noted that “obesity is associated with numerous poor health outcomes, including increased risk of cardiometabolic and respiratory disease and more severe viral disease including influenza, dengue, and SARS-CoV-1.

“Given the large scale of this study,” she said, “we have conclusively shown that being overweight or obese are independent risk factors for worse outcomes in adults hospitalized with COVID-19.”

“At the moment, the World Health Organization has not had enough high-quality data to include being overweight or obese as a risk factor for severe COVID-19 disease,” added another author, David P. Burgner, PhD, a pediatric infectious diseases clinician scientist from MCRI.

Does being overweight up risk of worse COVID-19 outcomes?

About 13% of the world’s population are overweight, and 40% have obesity. There are wide between-country variations in these data, and about 90% of patients with type 2 diabetes are overweight or obese, the researchers noted.

The Organisation for Economic Co-operation and Development reported that the prevalence of obesity in 2016-2017 was 5.7% to 8.9% in Asia, 9.8% to 16.8% in Europe, 26.5% in South Africa, and 40.0% in the United States, they added.

Obesity is common and has emerged as an important risk factor for severe COVID-19. However, most previous studies of COVID-19 and elevated BMI were conducted in single centers and did not focus on patients with overweight.

To investigate, the researchers identified 7,244 patients (two-thirds were overweight or obese) who were hospitalized with COVID-19 in 69 hospitals (18 sites) in 11 countries from Jan. 17, 2020, to June 2, 2020.

Most patients were hospitalized with COVID-19 in the Netherlands (2,260), followed by New York City (1,682), Switzerland (920), St. Louis (805), Norway, Italy, China, South Africa, Indonesia, Denmark, Los Angeles, Austria, and Singapore.

Just over half (60%) of the individuals were male, and 52% were older than 65.

Overall, 34.8% were overweight, and 30.8% had obesity, but the average weight varied considerably between countries and sites.
 

Increased need for respiratory support, same mortality risk

Compared with patients with normal weight, patients who were overweight had a 44% increased risk of needing supplemental oxygen/noninvasive ventilation, and those with obesity had a 75% increased risk of this, after adjustment for age (< 65, ≥ 65), sex, hypertension, diabetes, or preexisting cardiovascular disease or respiratory conditions.

Patients who were overweight had a 22% increased risk of needing invasive (mechanical) ventilation, and those with obesity had a 73% increased risk of this, after multivariable adjustment.

Being overweight or having obesity was not associated with a significantly increased risk of dying in the hospital, however.

“In other viral respiratory infections, such as influenza, there is a similar pattern of increased requirement for ventilatory support but lower in-hospital mortality among individuals with obesity, when compared to those with normal range BMI,” Dr. Longmore noted. She said that larger studies are needed to further explore this finding regarding COVID-19.

Compared to patients without diabetes, those with diabetes had a 21% increased risk of requiring invasive ventilation, but they did not have an increased risk of needing noninvasive ventilation or of dying in the hospital.

As in previous studies, individuals who had cardiovascular and preexisting respiratory diseases were not at greater risk of needing oxygen or mechanical ventilation but were at increased risk for in-hospital death. Men had a greater risk of needing invasive mechanical ventilation, and individuals who were older than 65 had an increased risk of requiring oxygen or of dying in the hospital.
 

A living meta-analysis, call for more collaborators

“We consider this a ‘living meta-analysis’ and invite other centers to join us,” Dr. Longmore said. “We hope to update the analyses as more data are contributed.”

No specific project funded the study. The authors have disclosed no relevant financial relationships.

In a global meta-analysis of more than 7,000 patients who were hospitalized with COVID-19, individuals with overweight or obesity were more likely to need respiratory support but were not more likely to die in the hospital, compared to individuals of normal weight.
 

Compared to patients without diabetes, those with diabetes had higher odds of needing invasive respiratory support (with intubation) but not for needing noninvasive respiratory support or of dying in the hospital.

“Surprisingly,” among patients with diabetes, being overweight or having obesity did not further increase the odds of any of these outcomes, the researchers wrote. The finding needs to be confirmed in larger studies, they said, because the sample sizes in these subanalyses were small and the confidence intervals were large.

The study by Danielle K. Longmore, PhD, of Murdoch Children’s Research Institute (MCRI), Melbourne, and colleagues from the International BMI-COVID consortium, was published online April 15 in Diabetes Care.

This new research “adds to the known data on the associations between obesity and severe COVID-19 disease and extends these findings” to patients who are overweight and/or have diabetes, Dr. Longmore, a pediatric endocrinologist with a clinical and research interest in childhood and youth obesity, said in an interview.

Immunologist Siroon Bekkering, PhD, of Radboud University Medical Center, Nijmegen, the Netherlands, explained that never before have so much data of different types regarding obesity been combined in one large study. Dr. Bekkering is a coauthor of the article and was a principal investigator.

“Several national and international observations already showed the important role of overweight and obesity in a more severe COVID-19 course. This study adds to those observations by combining data from several countries with the possibility to look at the risk factors separately,” she said in a statement from her institution.

Accelerated brain aging among HIV-infected adults might be caused in part by altered deep sleep patterns, new research suggests.

Using a measure known as the brain age index (BAI) – a machine-learning model that measures deviations in brain activity during sleep relative to healthy individuals – investigators identified 34 sleep electroencephalogram features that were significantly altered by HIV infection. The most notable of these was the decline in slow-wave activity during non-REM sleep, which has been previously associated with MRI markers of brain aging in healthy adults.

“One of the functions of slow-wave sleep appears to be its association with the glymphatic system, which clears [metabolic] waste products and supports memory consolidation,” study coauthor Brandon Westover, MD, PhD, associate professor of neurology at Massachusetts General Hospital/Harvard Medical School, Boston, said in an interview. “It’s also believed to be associated with an accelerated risk for dementia and other cognitive issues.”

Previous work conducted at Johns Hopkins and other institutions confirm Dr. Westerson’s hypothesis. Charlene Gamaldo, MD, medical director of Johns Hopkins Sleep Disorders Center in Baltimore, pointed to other study findings in patients with neurodegenerative disease that have shown a link between predominant habitual sleep positions and dementia, potentially driven by inefficient glymphatic transport. Dr. Gamaldo was not involved in the current study.
 

Threefold acceleration vs. healthy volunteers

“We’ve been grappling with whether people with HIV on ART experience accelerated aging or accentuated aging,” coauthor Shibani Mukerji, MD, PhD, associate director of the neuroinfectious diseases unit at Massachusetts General, said in an interview. “We have yet to have biomarkers to address this question, and most of the tools are limited to invasive or expensive diagnostics. “In general, sleep and its influence on health have been understudied in the HIV population.”

To address this question, the researchers retrospectively examined a Massachusetts General Hospital database of diagnostic sleep study participants from 2008 to 2018, identifying 3,155 healthy, HIV-negative control subjects and 43 HIV-positive participants. Thirty-four (79%) of the HIV-positive participants were men, 30 (70%) were White, and 38 (93%) were virally suppressed at the time of their sleep study. Four patients were taking efavirenz, 13 were taking an integrase strand transfer inhibitor, and all were adherent to antiretroviral therapy (ART) at the time of their sleep study.

None of the HIV-positive participants had a history of secondary brain infection or brain tumor, although one patient had recovered fully from a previous HIV-associated encephalitis.

The study findings, which were published online March 30, 2021, in Sleep, first showed that HIV-positive participants had an average BAI of 3.19 years (standard error of the mean,1.43 years), compared with the control participants, who had an average BAI of –0.16 (SEM, 0.18 years).

These findings held after adjustment for potential confounders (age, sex, race, tobacco use disorder, and alcohol use disorder), yielding a total effect of HIV on BAI of 3.35 years (P < .01).

“Despite being well controlled on ART, HIV-positive individuals who had participated in the sleep studies still had elevated brain age,” said Dr. Westover. “We didn’t have enough information to determine the pathways by which HIV increases the BAI, but chronic inflammation appears to be an important factor.”

The findings also demonstrated that comorbidities accounted for roughly a quarter of the effect of HIV on BAI. However, the lack of statistical significance (in part because of the limited sample size) precluded the ability to determine if treating or preventing them might influence the degree to which HIV affects BAI and, in turn, cognitive decline.
 

HIV, sleep EEG, and brain aging

To estimate the effect of HIV on specific EEG features, the investigators again evaluated the total effect, this time replacing BAI with individual sleep EEG as the primary outcome. Among the 34 EEG features significantly altered by HIV, none were observed in the wake state and three were altered in REM (each associated with reduced delta band power). The rest were distributed in non-REM sleep, most notably in the deepest phase, corresponding to relative reductions in delta wave power.

The study findings build on the investigators’ previous research, which demonstrated an association between greater mean BAI and dementia, psychotic disorders, and anxiety/mood disorders in HIV-negative subjects, all of which correlated to attenuated slow-wave sleep.

More research is needed to determine if BAI, as it relates to sleep EEG, can effectively track the risk for cognitive decline among HIV-positive people, and if certain confounders might attenuate or accelerate this risk.

“While our team has not specifically looked at BAI, the findings in this study seem perfectly in line with what we have found with our own research,” Dr. Gamaldo said in an interview. “Not only have we observed a robust association between minimal cognitive deficits and patients’ sleep complaints (despite being virally controlled), but also, the potential value of measuring the architectural sleep features by ambulatory EEG to identify HIV patients’ vulnerability to cognitive decline.”

“BAI is a physiologic, easily repeatable measurement that can be used to track if an intervention is having a good effect,” Dr. Westover said.

Dr. Mukerji concurred, adding that “having a tool that can be used in resource-challenged settings and also be incorporated into longitudinal studies in a patient population with substantial age-related comorbidities, like HIV, would be really helpful.”

Dr. Westover and Dr. Mukerji disclosed no relevant financial relationships. Dr. Gamaldo is a consultant for Jazz Pharmaceuticals, and has received author royalties from UpToDate and honoraria from Medscape CME for content contribution.

The other day, in a fairly common occurrence, I needed to fax a records request over to another office.

Not having memorized all the fax numbers in my area, I turned to the internet and quickly had their website and the needed information in front of me.

But at the top of the page, before you got to phone numbers and directions, was this statement in bold print (caps as seen):

“NOTICE TO ALL PATIENTS:

“Please show RESPECT AND KINDNESS to other patients and staff.

“We have a ZERO TOLERANCE policy for aggressive behavior, vulgar language, and violence, whether in person, on the phone, or online.”

A veterinarian I know recently put something similar up, saying: “We DO NOT TOLERATE physically or verbally abusive behavior by clients. We are compassionate and understand you are under stress, but we are also human and deserve respect. Thank you.”

I absolutely agree with this. Hell, I’m the same way.

But what is wrong with people that we actually need to have notices like that up?

Realistically, the vast majority of patients don’t need the reminder. They treat each other, and my staff, with politeness and respect, and we do the same. To me that’s part of the whole sandbox thing. Personally, I prefer my office to have the same atmosphere as a library, and am known to “shhhh” people who are too loud.

But the real point here is that we shouldn’t have to remind anyone else to behave with common courtesy. If you’re an adult, I’m going to assume your parents and teachers taught you the importance of manners and the Golden Rule.

I’ve been in practice for 23 years now, and I’ve never had to deal with this sort of behavior, this frequently, before. Is it that the pandemic, and its economic and social consequences, has gotten on everyone’s nerves? If so, hopefully it will gradually fade away as the crisis does. I’m vaccinated. My family and the majority of my patients are vaccinated. I encourage pretty much everyone who asks me about it to get vaccinated.

But I’m more concerned that isn’t really the issue. Maybe our polarized, divided society is moving in that direction. Common good is now often reduced to us against them, and the conditions of the times have just aggravated a problem that was festering.

The majority of people, of all beliefs, remain decent people. But it’s distressing that the amount of rudeness is increasing to the point where we need to remind grown-ups about its consequences.

Decency and manners, unfortunately, can’t be legislated. If you’ve forgotten yours, though, don’t think others will put up with you.

Pfizer CEO Albert Bourla, DVM, PhD, says an oral drug the company is developing to treat COVID-19 symptoms could be available to the public by the end of the year.

“If all goes well, and we implement the same speed that we are, and if regulators do the same, and they are, I hope that (it will be available) by the end of the year,” Dr. Bourla said on CNBC’s Squawk Box.

So far, the only antiviral drug authorized for use with COVID-19 is remdesivir, which is produced by Gilead Sciences and must be administered by injection in a health care setting.

An oral drug like the one Pfizer is developing could be taken at home and might keep people out of the hospital.

“Particular attention is on the oral because it provides several advantages,” Dr. Bourla said. “One of them is that you don’t need to go to the hospital to get the treatment, which is the case with all the injectables so far. You could get it at home, and that could be a game-changer.”

The drug might be effective against the emerging variants, he said. Pfizer is also working on an injectable antiviral drug.

Pfizer, with its European partner BioNTech, developed the first coronavirus vaccine authorized for use in the United States and Europe. The Pfizer pill under development would not be a vaccine to protect people from the virus but a drug to treat people who catch the virus.

The company announced in late March that it was starting clinical trials on the oral drug.

In a news release, the company said the oral drug would work by blocking protease, a critical enzyme that the virus needs to replicate. Protease inhibitors are used in medicines to treat HIV and hepatitis C.

A coronavirus vaccine that could be taken as a pill may enter clinical trials in the second quarter of 2021. The oral vaccine is being developed by Oravax Medical, a new joint venture of the Israeli-American company Oramed and the Indian company Premas Biotech. So far, all coronavirus vaccines are injectable.

When it comes to SARS-CoV-2 infection among patients with multiple sclerosis (MS), disease-modifying therapies (DMTs) seem to have varying effects on risk of worse outcomes, according to a new analysis of an Italian cohort of patients with MS. The study confirmed that steroid exposure in the month before COVID-19 symptom onset is tied to more severe disease, and anti-CD20 therapy poses similar risks. But the researchers noted that interferon and possibly teriflunomide were associated with a protective effect in the multivariate analysis.

Maria Pia Sormani, PhD, who is a professor of biostatistics at the University of Genoa, presented the study at the 2021 annual meeting of the American Academy of Neurology.

The results confirm some previous analyses, and add to the body of evidence clinicians rely on, according to Jiwon Oh, MD, PhD, who moderated the session. “These data about the risk with the anti-CD20 therapies have been around for a while, but it seems that risk is pretty apparent, with this registry and other registries around the world. It affects counseling to patients on anti-CD20 therapies. We would counsel them to be cautious, obviously, follow public health precautions, but maybe be even more cautious. It affects our recommendations about the urgency of vaccination in these folks, how high priority they should be,” Dr. Oh said in an interview. She is the clinical director of the Barlo MS Center at St. Michael’s Unity Health in Toronto.

The analysis also hinted at complexities within demographics that might help explain some of the differing outcomes of infections. “We have learned that the course of the viral infection per se may not be the cause of severe outcomes, but the exaggerated inflammatory response to the virus is mainly responsible for intubations and deaths. The hypothesis we are investigating is whether anti-CD20 therapies can cause a more severe viral infection (that is something already known for other viral infections) but do not play a crucial role in causing the explosion of the inflammatory process,” said Dr. Sormani in an email.

The group plans to look at the risk of anti-CD20 therapies in different age groups, “to try to understand the underlying mechanism through which anti-CD20 increases the risk of more severe outcome,” she said.

Dr. Sormani presented an analysis of 3,274 patients with MS who contracted COVID-19 in Italy. The mean age was 44, the median Expanded Disability Status Scale (EDSS) score was 2, Among the study cohort, 68.6% were female; 14% had progressive MS and 26 patients died. Patients who died had a mean age of 63, 48% were female, 73% had progressive MS, and 50% were not on any DMT.

The researchers used ordinal logistic regression that “orders” outcome on a severity scale of 0 (mild disease, no pneumonia or hospitalization), 1 (pneumonia or hospitalization, n = 184), or 2 (ICU admission or death, n = 36). They calculated the odds ratio of moving from 0 to 1, or 1 to 2, and carried the assumption that the risk is the same. For example, an odds ratio of 2 for males versus females would mean that males are twice as likely to be hospitalized and twice as likely to go from being hospitalized to going to the ICU or dying.

The researchers found that older age, male sex, and comorbidities increase risk of worse COVID-19 outcomes. Exposure to methylprednisolone 1 month before COVID-19 symptom onset carried an increased risk (OR, 2.33; P = .03). Compared with no therapy, receiving interferon was associated with lower risk (OR, 0.34; P = .009) and teriflunomide trended towards an association with better outcomes (OR, 0.49; P = .054). Anti-CD20 treatment (ocrelizumab or rituximab) was linked to worse outcomes (OR, 1.89; P = .012) overall, which held up when ocrelizumab (OR, 1.71; P = .04) and rituximab (OR, 2.77; P = .03) were considered separately.

To understand why the risk of ocrelizumab might be lower, the researchers examined risk by duration of anti-CD20 treatment, and found that risk increased with increased duration of treatment, with the lowest risk at treatment duration less than 6 months (OR, 1.56; 95% CI, 0.65-3.77; not significant), followed by 6 months to 1 year (OR, 1.68; 95% CI, 0.69-4.03; P < .001), 1-2 years (OR, 1.74; 95% CI, 0.83-3.64; trend), and the highest risk at more than 2 years (OR, 2.75; 95% CI, 1.28-5.88).

Dr. Sormani suggested that the greater risk associated with rituximab may be because of a tendency towards longer treatment length, since patients treated with rituximab were more often treated for greater lengths of time; 11% had been treated for 6 months or less (vs. 24% of ocrelizumab patients); 26%, 6-12 months (vs. 18% ocrelizumab); 19%, 1-2 years (vs. 37% ocrelizumab); and 44%, 2 years or longer (vs. 21% ocrelizumab).

Vagus nerve stimulation (VNS) paired with intensive rehabilitation for moderate to severe arm weakness months or even years after stroke may lead to a greater improvement in arm function than rehabilitation alone, according to preliminary results of a randomized clinical trial at the 2021 annual meeting of the American Academy of Neurology.

“We believe that vagus nerve stimulation combined with rehabilitation is an acceptable and effective intervention for improving upper-limb impairment and function in people with moderate to severe arm weakness a long time VNS-REHAB pivotal study is a randomized, blinded, controlled trial of 108 people who had upper-extremity weakness after having a stroke at least 9 months before enrollment. The average for the group was 3 years post stroke after ischemic stroke,” said Jesse Dawson, MD, a professor at the University of Glasgow.

The Fifty-three patients were assigned active VNS followed by 6 weeks of in-clinic rehabilitation and then 90 days of home-based rehab. At in-clinic rehab, the therapist initiated a 5-second burst of VNS stimulation during each movement. In home-base treatment, the device was activated by a magnet.

Fifty-five patients were assigned sham VNS. After 90 days, the sham group crossed over to receive VNS for 6 weeks and then 90 days of home exercise. This crossover group was the focus of the data Dr. Dawson presented at AAN 2021. The overall trial results have been published in the Lancet.

“The hypothesis is based on the knowledge that the VNS stimulates the release of proneuroplastic neuromodulators norepinephrine and acetylcholine,” Dr. Dawson said. “By pairing VNS with task-specific movement, we hypothesize that we will increase task-specific neuroplasticity.”

The main study showed “a statistically significant difference across all primary and secondary endpoints at all time points in favor of rehabilitation paired with VNS,” Dr. Dawson said. The primary outcome was improvement in Fugl-Meyer Upper Extremity (FMA-UE) outcome, with the active VNS group having a significantly higher percentage of responders. For example, 47% of the active VNS patients had a greater than 6-point response on FMA-UE improvement versus 27% of the sham group (P = .010).

When the sham group crossed over to active VNS, the improvement in arm function matched that of the treatment group in the main study, Dr. Dawson said. “If you look at specifically what happened after they completed the control phase, there was a further small increase in Fugl-Meyer score, but, more importantly between 20% and 35% achieved a clinically important response on the Fugl-Meyer assessment or the Wolf Motor Function Test, giving a number need to treat ranging from three to five,” he said.

Dr. Dawson said that data on adverse events was presented in the Lancet publication. “These were observed at expected frequencies,” he said.

In an interview, he explained the significance of reporting the number to treat. “The number needed to treat helps give an idea of how many times you need to do something to achieve the desired outcome. So for VNS paired with rehab versus rehab alone, you need to treat four people to get one extra clinically important response, compared with just doing therapy.”

The next steps for his group’s research, he said, “will be to try and explore whether we can predict who responds best, and we would like to see if people with other types of stroke benefit.”

In providing comment on the study, Andreas Luft, MD, a professor at the University Hospital Zürich, noted that the FME-UE score improvements reported “are significant and meaningful. ... However, they may also be achieved by increasing the intensity of training. Many medical systems offer their patients high rehabilitation intensities and achieve similar improvements. Whether VNS can further boost higher-intensity training ‘beyond its limits’ is probable but remains to be demonstrated.”

Dr. Luft noted the study advances the knowledge of combining a therapeutic approach with training. “More such approaches are necessary to increase the therapeutic instrumentation of neurorehabilitation,” he said.

Dr. Dawson reported a financial relationship with MicroTransponder. His coauthors reported relationships with MicroTransponder, SanBio, Fujifilm Toyoma Chemical, Medtronic, TRCare, SAEBO, Allergan/AbbVie, Ipsen, Merz, Ottobock/Hangar Orthopedics, Parker Hannifin, Revance Therapeutics, ReWallk, and Sword Health.

Vagus nerve stimulation (VNS) paired with intensive rehabilitation for moderate to severe arm weakness months or even years after stroke may lead to a greater improvement in arm function than rehabilitation alone, according to preliminary results of a randomized clinical trial at the 2021 annual meeting of the American Academy of Neurology.

“We believe that vagus nerve stimulation combined with rehabilitation is an acceptable and effective intervention for improving upper-limb impairment and function in people with moderate to severe arm weakness a long time VNS-REHAB pivotal study is a randomized, blinded, controlled trial of 108 people who had upper-extremity weakness after having a stroke at least 9 months before enrollment. The average for the group was 3 years post stroke after ischemic stroke,” said Jesse Dawson, MD, a professor at the University of Glasgow.

The Fifty-three patients were assigned active VNS followed by 6 weeks of in-clinic rehabilitation and then 90 days of home-based rehab. At in-clinic rehab, the therapist initiated a 5-second burst of VNS stimulation during each movement. In home-base treatment, the device was activated by a magnet.

Fifty-five patients were assigned sham VNS. After 90 days, the sham group crossed over to receive VNS for 6 weeks and then 90 days of home exercise. This crossover group was the focus of the data Dr. Dawson presented at AAN 2021. The overall trial results have been published in the Lancet.

“The hypothesis is based on the knowledge that the VNS stimulates the release of proneuroplastic neuromodulators norepinephrine and acetylcholine,” Dr. Dawson said. “By pairing VNS with task-specific movement, we hypothesize that we will increase task-specific neuroplasticity.”

The main study showed “a statistically significant difference across all primary and secondary endpoints at all time points in favor of rehabilitation paired with VNS,” Dr. Dawson said. The primary outcome was improvement in Fugl-Meyer Upper Extremity (FMA-UE) outcome, with the active VNS group having a significantly higher percentage of responders. For example, 47% of the active VNS patients had a greater than 6-point response on FMA-UE improvement versus 27% of the sham group (P = .010).

People with psoriasis have a higher risk of infection with COVID-19 than the general population, but some systemic treatments appear to lower risk in patients, compared with those on topical therapy, a new study finds.

“Our study results suggest that psoriasis is an independent risk factor for COVID-19 illness,” study coauthor Jeffrey Liu, a medical student at the University of Southern California, Los Angeles, said in an interview after he presented the findings at the American Academy of Dermatology Virtual Meeting Experience. “And our findings are consistent with the hypothesis that certain systemic agents may confer a protective effect against COVID-19 illness.”

Mr. Liu and coinvestigators used a Symphony Health dataset to analyze the health records of 167,027 U.S. patients diagnosed with psoriasis and a control group of 1,002,162 patients. The participants, all at least 20 years old, had been treated for psoriasis or psoriatic arthritis from May 2019 through Jan. 1, 2020, and were tracked until Nov. 11, 2020.

The ages and races of peoples in the two groups were roughly similar. Overall, 55% were women and 75% were White, and their average age was 58 years. Type 2 diabetes was more common in the psoriasis group than the control group (23% vs. 16%), as was obesity (27% vs. 15%). Of the patients with psoriasis, 60% were on topical treatments, 19% were on oral therapies, and 22% were on biologic therapy, with only a few taking both oral and biologic therapies.

After adjustment for age and gender, patients with psoriasis were 33% more likely than the control group to develop COVID-19 (adjusted incidence rate ratio, 1.33; 95% confidence interval, 1.23-1.38; P < .0001).

In a separate analysis, the gap persisted after adjustment for demographics and comorbidities: Patients with psoriasis had a higher rate of COVID-19 infection vs. controls (adjusted odds ratio, 1.18; 95% CI, 1.13-1.23; P < .0001). Among all patients, non-White race, older age, and comorbidities were all linked to higher risk of COVID-19 (all P < .0001).

Psoriasis might make patients more vulnerable to COVID-19 because the presence of up-regulated genes in psoriatic skin “may lead to systemic hyperinflammation and sensitization of patients with psoriasis to proinflammatory cytokine storm,” Mr. Liu said. This, in turn, may trigger more severe symptomatic disease that requires medical treatment, he said.

Reduced risk, compared with topical therapies

After adjustment for age and gender, those treated with TNF-alpha inhibitors, methotrexate, and apremilast (Otezla) all had statistically lower risks of COVID-19 vs. those on topical therapy (aIRR, 0.82; 95% CI, 0.69-0.95; P < .0029 for TNF-alpha inhibitors; aIRR, 0.75; 95% CI, 0.67-0.86; P < .0001 for methotrexate; and aIRR, 0.69; 95% CI, 0.55-0.85; P < .0006 for apremilast).

Reduced risk held true for those in the separate analysis after adjustment for comorbidities and demographics (respectively, aOR, 0.87; 95% CI, 0.77-1.00; P < .0469; aOR, 0.81; 95% CI, 0.71-0.92; P < .0011; and aOR, 0.70; 95% CI, 0.57-0.87; P < .0014).

Apremilast and methotrexate may boost protection against COVID-19 by inhibiting the body’s production of cytokines, Mr. Liu said.

One message of the study is that “dermatologists should not be scared of prescribing biologics or oral therapies for psoriasis,” the study’s lead author Jashin J. Wu, MD, of the Dermatology Research and Education Foundation in Irvine, Calif., said in an interview.

However, the results on the effects of systemic therapies were not all positive. Interleukin (IL)–17 inhibitors were an outlier: After adjustment for age and gender, patients treated with this class of drugs were 36% more likely to develop COVID-19 than those on oral agents (aIRR, 1.36; 95% CI, 1.13-1.63; P < .0009).

Among patients on biologics, those taking IL-17 inhibitors had the highest risk of COVID-19, Mr. Liu said. “The risk was higher in this class regardless of reference group – general population, the topical cohort, and the oral cohort,” he said. “This may relate to the observation that this biologic class exerts more broad immunosuppressive effects on antiviral host immunity. Notably, large meta-estimates of pivotal trials have observed increased risk of respiratory tract infections for patients on IL-17 inhibitors.”

In an interview, Erica Dommasch, MD, MPH, of the department of dermatology at Beth Israel Deaconess Medical Center, Boston, cautioned that “the data from this study is very hard to interpret.”

It’s likely that some patients with psoriasis on systemic medications “may have been the most careful about limiting exposures,” she said. “Thus, it’s hard to account for behavioral changes in individuals that may have led to the decreased incidence in psoriasis in patients on systemic agents versus topical therapy alone.”

Patients with psoriasis may also be tested more often for COVID-19, and unmeasured comorbidities like chronic kidney disease may play a role too, she said. Still, she added, “it’s reassuring that the authors did not find an increased rate of COVID among psoriasis patients on systemic agents versus topicals alone.” And she agreed with Dr. Wu about the importance of treating psoriasis with therapy beyond topical treatments during the pandemic: “Providers should feel comfortable prescribing systemic medications to psoriasis patients when otherwise appropriate.”

As for the next steps, Dr. Wu said, “we will be exploring more about the prognosis of COVID-19 infection in psoriasis patients. In addition, we will be exploring the relationship of COVID-19 infection with other inflammatory skin diseases, such as atopic dermatitis.”

No study funding is reported. Dr. Wu discloses investigator, consultant, or speaker relationships with AbbVie, Almirall, Amgen, Arcutis, Aristea Therapeutics, Boehringer Ingelheim, Bristol-Myers Squibb, Dermavant, Dr. Reddy’s Laboratories, Eli Lilly, Galderma, Janssen, LEO Pharma, Mindera, Novartis, Regeneron, Sanofi Genzyme, Solius, Sun Pharmaceutical, UCB, Valeant Pharmaceuticals North America, and Zerigo Health.

After hinting that new guidelines on outdoor mask-wearing were coming, the Centers for Disease Control and Prevention on April 27 officially gave a green light to fully vaccinated people gathering outside in uncrowded activities without the masks that have become so common during the COVID-19 pandemic.

It is a minor – but still significant – step toward the end of pandemic restrictions.

“Over the past year, we have spent a lot of time telling Americans what they cannot do, what they should not do,” CDC director Rochelle Walensky, MD, MPH, said at a White House press briefing. “Today, I’m going to tell you some of the things you can do if you are fully vaccinated.”

President Joe Biden affirmed the new guidelines at a press conference soon after the CDC briefing ended.

“Starting today, if you are fully vaccinated and you’re outdoors and not in a big crowd, you no longer need to wear a mask,” he said, adding “the bottom line is clear: If you’re vaccinated, you can do more things, more safely, both outdoors as well as indoors.”

President Biden emphasized the role science played in the decision, saying “The CDC is able to make this announcement because our scientists are convinced by the data that the odds of getting or giving the virus to others is very, very low if you’ve both been fully vaccinated and are out in the open air.”

President Biden also said these new guidelines should be an incentive for more people to get vaccinated. “This is another great reason to go get vaccinated now. Now,” he said.

The CDC has long advised that outdoor activities are safer than indoor activities.

“Most of transmission is happening indoors rather than outdoors. Less than 10% of documented transmissions in many studies have occurred outdoors,” said Dr. Walensky. “We also know there’s almost a 20-fold increased risk of transmission in the indoor setting, than the outdoor setting.”

Dr. Walensky said the lower risks outdoors, combined with growing vaccination coverage and falling COVID cases around the country, motivated the change.

The new guidelines come as the share of people in the United States who are vaccinated is growing. About 37% of all eligible Americans are fully vaccinated, according to the CDC. Nearly 54% have had at least one dose.

The new guidelines say unvaccinated people should continue to wear masks outdoors when gathering with others or dining at an outdoor restaurant.

And vaccinated people should continue to wear masks outdoors in crowded settings where social distancing might not always be possible, like a concert or sporting event. People are considered fully vaccinated when they are 2 weeks past their last shot

The CDC guidelines say people who live in the same house don’t need to wear masks if they’re exercising or hanging out together outdoors.

You also don’t need a mask if you’re attending a small, outdoor gathering with fully vaccinated family and friends, whether you’re vaccinated or not.

The new guidelines also say it’s OK for fully vaccinated people to take their masks off outdoors when gathering in a small group of vaccinated and unvaccinated people, but suggest that unvaccinated people should still wear a mask.

“Over the past year, we have spent a lot of time telling Americans what they cannot do, what they should not do,” CDC director Rochelle Walensky, MD, MPH, said at a White House press briefing. “Today, I’m going to tell you some of the things you can do if you are fully vaccinated.”

President Joe Biden affirmed the new guidelines at a press conference soon after the CDC briefing ended.

“Starting today, if you are fully vaccinated and you’re outdoors and not in a big crowd, you no longer need to wear a mask,” he said, adding “the bottom line is clear: If you’re vaccinated, you can do more things, more safely, both outdoors as well as indoors.”

President Biden emphasized the role science played in the decision, saying “The CDC is able to make this announcement because our scientists are convinced by the data that the odds of getting or giving the virus to others is very, very low if you’ve both been fully vaccinated and are out in the open air.”

President Biden also said these new guidelines should be an incentive for more people to get vaccinated. “This is another great reason to go get vaccinated now. Now,” he said.

The CDC has long advised that outdoor activities are safer than indoor activities.

“Most of transmission is happening indoors rather than outdoors. Less than 10% of documented transmissions in many studies have occurred outdoors,” said Dr. Walensky. “We also know there’s almost a 20-fold increased risk of transmission in the indoor setting, than the outdoor setting.”

Dr. Walensky said the lower risks outdoors, combined with growing vaccination coverage and falling COVID cases around the country, motivated the change.

The new guidelines come as the share of people in the United States who are vaccinated is growing. About 37% of all eligible Americans are fully vaccinated, according to the CDC. Nearly 54% have had at least one dose.

The new guidelines say unvaccinated people should continue to wear masks outdoors when gathering with others or dining at an outdoor restaurant.

And vaccinated people should continue to wear masks outdoors in crowded settings where social distancing might not always be possible, like a concert or sporting event. People are considered fully vaccinated when they are 2 weeks past their last shot

The CDC guidelines say people who live in the same house don’t need to wear masks if they’re exercising or hanging out together outdoors.

You also don’t need a mask if you’re attending a small, outdoor gathering with fully vaccinated family and friends, whether you’re vaccinated or not.

The new guidelines also say it’s OK for fully vaccinated people to take their masks off outdoors when gathering in a small group of vaccinated and unvaccinated people, but suggest that unvaccinated people should still wear a mask.
