The Brazilian National Health Surveillance Agency (Anvisa) announced Oct. 21 that it is investigating data received on the death of a volunteer in a clinical trial of the COVID-19 vaccine developed by Oxford University and the pharmaceutical company AstraZeneca.

In an email sent to Medscape Medical News, the agency states that it was formally informed of the death on October 19. It has already received data regarding the investigation of the case, which is now being conducted by the Brazilian International Security Assessment Committee.

The identity of the volunteer and cause of death have not yet been confirmed by any official source linked to the study. In the email, Anvisa reiterated that “according to national and international regulations on good clinical practices, data on clinical research volunteers must be kept confidential, in accordance with the principles of confidentiality, human dignity, and protection of participants.”

A report in the Brazilian newspaper O Globo, however, states that the patient who died is a 28-year-old doctor, recently graduated, who worked on the front line of combating COVID-19 in three hospitals in Rio de Janeiro. He reportedly died Oct. 15 due to complications from COVID-19. The newspaper report said he received a dose of the AZDI222 vaccine in late July. Due to the study design, it is impossible to know whether the volunteer received the vaccine or placebo.

It is imperative to wait for the results of the investigations, said Sergio Cimerman, MD, the scientific coordinator of the Brazilian Society of Infectious Diseases (SBI), because death is possible during any vaccine trial, even more so in cases in which the final goal is to immunize the population in record time.

“It is precisely the phase 3 study that assesses efficacy and safety so that the vaccine can be used for the entire population. We cannot let ourselves lose hope, and we must move forward, as safely as possible, in search of an ideal vaccine,” said Cimerman, who works at the Instituto de Infectologia Emílio Ribas and is also an advisor to the Portuguese edition of Medscape.

Neutrophil granulocyte biomarkers can distinguish between neuromyelitis optica spectrum disorders (NMOSD) and anti-MOG antibody–associated disease (MOGAD) on one hand and multiple sclerosis (MS) on the other hand, researchers reported. If current findings are replicated, these biomarkers will help neurologists distinguish between these disorders in the future, even in cases that are negative for autoantibodies, they said.

The sensitivity and specificity profile of neutrophil granulocyte biomarkers is not as good as that for cell-based assays for AQP4 and anti-MOG antibodies when it comes to distinguishing between acute NMOSD or MOGAD versus acute relapsing-remitting MS, said David Leppert, MD, of University Hospital Basel (Switzerland) and the University of Basel. But the sensitivity and specificity of neutrophil granulocyte biomarkers are “even with” those of referring ELISA tests, he added. Furthermore, the evaluation of these biomarkers can be completed within hours, thus providing the potential for timely support for therapeutic decisions about patients with acute NMOSD.

It can be difficult to distinguish between NMOSD, MOGAD, and MS using a clinical examination and MRI scans alone. Assays for AQP4 and anti-MOG antibodies are the standard for refining the diagnosis, but obtaining the results of these assays takes 1-2 weeks. This time frame may delay the administration of urgently needed treatment.

Neutrophil granulocytes have various components that carry molecules that, although they are secreted to defend the host, also can damage tissue. These cells are common in brain tissue and CSF among patients with NMOSD. Patients with MOGAD often have neutrophil granulocytes as well, but the latter are rare in MS.
 

Biomarkers had high AUC

Dr. Leppert and colleagues conducted a study to evaluate whether these cells can distinguish NMOSD or MOGAD from MS. The investigators specifically examined the following neutrophil granule products: elastase, myeloperoxidase (MPO), matrix metalloproteinase-8 (MMP-8), and neutrophil gelatinase-associated lipocalin (NGAL). Dr. Leppert’s group evaluated CSF samples from 42 patients with NMOSD, 6 patients with MOGAD, and 41 patients with relapsing-remitting MS for these potential biomarkers. They also examined the samples for neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and S100B by conventional ELISA or single-molecule array assay. The investigators examined CSF samples from 25 healthy controls as a reference group.

Linear models allowed Dr. Leppert and colleagues to assess the association between biomarkers and disease groups. The investigators modeled the change of biomarker levels over time. They calculated receiver operating characteristic (ROC) curves and area under the curve (AUC) to estimate the potential to distinguish NMOSD and MOGAD from relapsing-remitting MS in acute disease phase (i.e., at 20 or fewer days after relapse), as well as between acute NMOSD and MOGAD. Finally, they assessed the association of biomarkers with Expanded Disability Status Scale (EDSS) score in acute NMOSD and relapsing-remitting MS using linear models and Spearman correlation.

Dr. Leppert and colleagues found that levels of NfL were increased among patients, compared with healthy controls. GFAP levels were increased in patients with NMOSD, compared with controls.

Among patients with NMOSD, all four neutrophil granulocyte markers were significantly increased, compared with healthy controls and patients with acute relapsing-remitting MS. Among patients with MOGAD, elastase, MPO, and MMP-8 were increased, compared with healthy controls and patients with acute relapsing-remitting MS. In ROC analyses comparing patients with acute NMOSD or MOGAD against those with acute RRMS, the AUC of elastase and NGAL was 0.91, the AUC of MPO was 0.82, and the AUC of MMP-8 was 0.81.

Levels of S100B were increased in 89% of patients with acute NMOSD (AUC = 0.82), and levels of GFAP were increased in 83% of patients with acute NMOSD (AUC = 0.80), compared with median values of MOGAD. Among patients with acute NMOSD, EDSS scores correlated with all four neutrophil granulocyte markers and GFAP, but not with NfL and S100B. The neutrophil granulocyte markers in acute NMOSD are likely drivers of tissue damage, said Dr. Leppert. “We may end up in the future with an algorithm that combines several markers into one score to optimize the differentiating power.” The next step will be to validate these findings in a larger sample set, he said at the Joint European Committee for Treatment and Research in Multiple Sclerosis–Americas Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS-ACTRIMS) 2020, this year known as MSVirtual2020.
 

Biomarkers may predict attacks

Granulocyte markers may provide support for a diagnosis of NMOSD over MS even in the small subgroup of patients who are seronegative for AQP4-IgG and MOG-IgG, said Brian G. Weinshenker, MD, a neurology consultant at Mayo Clinic in Rochester, Minn. In the study by Leppert and colleagues, granulocyte markers did not appear able to distinguish patients with AQP4-IgG–associated NMOSD from those with MOG-IgG–associated NMOSD, although astrocyte markers did in previous studies. “Granulocyte markers are primarily effective when studied in the context of an acute attack, unlike the antibody biomarkers,” said Dr. Weinshenker.

“Perhaps the most promising aspect of these new biomarkers is the fact that they are biomarkers for important mediators of tissue toxicity and seemed to correlate with attack-related disability,” he added. “They may prove to be prognostic indicators of attacks, and might influence the aggressiveness of acute management of attacks, although, in practice, all patients with NMOSD attacks, especially those associated with AQP4-IgG, should be managed aggressively.”

The current results will need independent confirmation before these biomarkers can be integrated into clinical practice, said Dr. Weinshenker. Studies should include patients with other diseases that can cause inflammation in the spinal cord and optic nerve (e.g., acute disseminated encephalomyelitis, infectious myelitis, and parainfectious myelitis) as relevant controls to determine whether granulocyte markers can distinguish these conditions effectively.

In addition, patients with discrepant values for elevations of granulocyte markers and serological indicators of NMOSD should be followed to determine the markers’ significance in this population, as well as to understand the value that measuring neutrophil markers provides. “Further studies of how these markers might herald attacks and predict disability might render these tests useful in monitoring patients and potentially intervening early in the attack process before attacks are fully manifest clinically.”

Dr. Leppert did not report any disclosures or any outside funding for the study. Dr. Weinshenker receives royalties from RSR, Oxford University, Hospices Civil de Lyon, and MVZ Labor PD Dr. Volkmann und Kollegen for a patent on NMO-IgG as a diagnostic test for NMOSD. He has served on an adjudication committee for clinical trials in NMOSD being conducted by MedImmune/VielaBio and Alexion, and consulted for Chugai/Roche/Genentech and Mitsubishi-Tanabe regarding a clinical trial for NMOSD.

While the spring peak of COVID-19 was tough and traumatic for many residents and interns in a New York City health system, the experience may have accelerated their patient communication skills regarding difficult goals-of-care discussions, results of a recent survey suggest.

Breaking bad news was an everyday or every-other-day occurrence at the peak of the pandemic for nearly all of 50 of the trainees surveyed, who had worked at hospitals affiliated with the internal medicine residency program at the at the Icahn School of Medicine at Mount Sinai from March to June 2020.

However, trainees became significantly more comfortable and fluent in goals-of-care discussions during the pandemic, according to Patrick Tobin-Schnittger, MBBS, a third-year internal medicine resident in the Mount Sinai program.

“COVID-19 has obviously made a huge impact on the world, but I think it’s also made a huge impact on a whole generation of junior doctors,” said Dr. Tobin-Schnittger, who presented the findings in a late-breaking abstract session at the CHEST Annual Meeting, held virtually this year.

“It’ll be interesting to see what happens in the future as that generation matures, and I think one of the things is that we’re a lot more comfortable with end-of-life care,” he said in an interview conducted during the conference.

Nevertheless, coping with death may still be a challenge for many residents, according to Dr. Tobin-Schnittger. In the survey, internal medicine residents who had rarely encountered patient deaths suddenly found themselves experiencing deaths weekly, with more than one in five saying they were encountering it every day.

When asked to self-rate themselves according to Bugen’s Coping With Death scale, most participants had scores that suggested their ability to cope was suboptimal, the researcher said.

To help trainees cope with local COVID-19 surges, internal medicine residency programs should be implementing “breaking bad news” workshops and educating house staff on resilience in times of crisis, especially if it can be done virtually, according to Dr. Tobin-Schnittger.

“That could be done pretty quickly, and it could be done remotely so people could practice this from home,” he explained. “They wouldn’t even need to congregate in a big room.”

As a “mini-surge” of COVID-19 cases hits the United States, teaching self-care and coping techniques may also be important, said Mangala Narasimhan, DO, FCCP, director of critical care services at Northwell Health in New York City.

In patients with tuberous sclerosis complex (TSC), preventive treatment with vigabatrin is safe and changes the natural history of seizures, according to research presented at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year. This treatment strategy reduces the risk and severity of epilepsy, said the investigators.

As much as 90% of patients with TSC have epilepsy. Seizures generally start during infancy and are often resistant to medication. Clinicians are increasingly able to diagnose TSC prenatally, thus creating an opportunity for pursuing preventive strategies.

In the multicenter EPISTOP trial, Katarzyna Kotulska, MD, head of neurology and epileptology at Children’s Memorial Health Institute in Warsaw, and colleagues compared the efficacy and safety of preventive vigabatrin treatment with those of conventional vigabatrin treatment in infants with TSC. The researchers followed 94 infants with TSC and without a history of seizures with monthly video EEG. Conventional treatment was initiated after the first electrographic or clinical seizure, and preventive treatment was administered when epileptiform discharges were visible on EEG but before the first seizure.

Six sites randomly assigned patients to treatment in a equal groups in a randomized, controlled trial. At four other sites, treatment allocation was fixed in an open-label trial. All patients were followed until age 2 years. The study’s primary endpoint was the time to first clinical seizure.

A total of 53 patients participated in the randomized, controlled trial, and 41 participated in the open-label study; 79 patients completed the study. Of this group, 25 received preventive treatment, 25 received conventional treatment, and 22 patients had seizures before epileptiform activity was detected on EEG. Seven patients had neither seizures nor abnormal EEG.

The time to first clinical seizure was significantly longer in patients who received preventive treatment, compared with those who received conventional treatment. In the randomized, controlled trial, time to first seizure was 364 days in the preventive treatment group and 124 days in the conventional treatment group. In the open-label trial, time to first seizure was 426 days in the preventive treatment group and 106 days in the conventional treatment group.

A pooled analysis indicated that, at 24 months, preventive treatment significantly reduced the risk of clinical seizures (odds ratio, 0.21), drug-resistant epilepsy (OR, 0.23), and infantile spasms (OR, 0). The investigators did not record any adverse events related to preventive treatment.

The study was funded by the 7th Framework Program of the European Union. Dr. Kotulska did not report any disclosures.

Children with stereotypies consult neurologists less often than do those with tics, according to an analysis presented at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year. The former also are younger at their first visit than are the latter. Compared with children with tics, children with stereotypies also have fewer comorbidities and receive fewer recommendations for interventions. This difference between groups may not merely reflect the younger age at presentation of children with stereotypies (e.g., at an age before a comorbidity is manifest). “At least in our population, it does seem to reflect an overall lower burden of comorbidities,” said Shannon Dean, MD, PhD, assistant professor of neurology at the Kennedy Krieger Institute of Johns Hopkins University in Baltimore.

Common pediatric movement disorders

Tics (i.e., short-lasting, sudden, repetitive movements) and stereotypies (i.e., rhythmic, fixed, deliberate, but purposeless movements) are common pediatric movement disorders with favorable prognoses. The disorders share several comorbidities, the most common of which are ADHD, anxiety, and obsessive-compulsive disorder (OCD). Dr. Dean and colleagues examined differences in comorbidity burden, resource use, and need for intervention between children with tics and those with stereotypies.

The investigators performed a retrospective chart review and identified 63 children diagnosed with stereotypies. They matched each of these children, by age when possible, with a child first diagnosed with a chronic or provisional tic disorder during the same year. All patients presented to the University of Rochester (N.Y.) Child Neurology Clinic between 2003 and 2016. Dr. Dean and colleagues excluded children with diagnoses for which stereotypies are considered a secondary feature (e.g., autism, intellectual disability, and blindness). They also excluded children who had tics and stereotypies.

The researchers examined the groups’ total number of visits, comorbidities, and recommended interventions. They also analyzed data from a follow-up survey that were available for 20 of the 63 patients with stereotypies. They tested continuous or discrete variables for normal distribution and used T tests or Mann–Whitney U as appropriate. To analyze categorical data, they used chi squared or Fisher’s exact test for groups smaller than five.
 

Differing rates of intervention

Children with stereotypies were younger at first visit (mean age, 5.6 years vs. 7.1 years) and at last visit (mean age, 6.5 years vs. 9.8 years) and had fewer total visits (1.8 vs. 4.5), compared with children with tics.

The three most common comorbidities in the population were more prevalent among patients with tics than among patients with stereotypies. The prevalence of ADHD was 27% among patients with stereotypies and 48% among patients with tics. The prevalence of OCD was 8% among children with stereotypies and 41% among children with tics. The prevalence of anxiety was 21% among children with stereotypies and 63% among children with tics. Children with stereotypies also had fewer neuropsychiatric comorbidities overall than did children with tics (0.7 per patient versus 1.9 per patient).

The clinicians had recommended at least one medication for tics in 22% of the children with tics. No medication is available for children with stereotypies. The clinicians recommended behavioral therapy for 13% of the children with tics, but for none of the children with stereotypies, “because none of them had functional impairment that would warrant intervention,” said Dr. Dean. The clinicians also made more recommendations for pharmaceutical and behavioral treatments for comorbidities in patients with tics than in patients with stereotypies.

When the investigators examined the follow-up survey data, they found that patients with stereotypies were older at last contact than patients with tics. Last contact was defined as the time of the survey for patients with stereotypies and the time of the last clinic visit for patients with tics. When Dr. Dean and colleagues examined the three most common comorbidities, however, they again found that the burden was greater among patients with tics (1.5 per patient) than among patients with stereotypies (0.8 per patient).

The study was funded by the T32 Experimental Therapeutics Training Grant from the University of Rochester, N.Y. Dr. Dean did not report any disclosures.

After taking a nosedive during the initial wave of the COVID-19 pandemic, then rising and plateauing, weekly outpatient visits in the United States have rebounded and now slightly exceed levels seen in late February, according to new data.

Overall visits plunged by almost 60% at the low point in late March and did not start recovering until late June, when visits were still off by 10%. Visits began to rise again – by 2% over the March 1 baseline – around Labor Day.

As of Oct. 4, visits had returned to that March 1 baseline, which was slightly higher than in late February, according to data analyzed by Harvard University, the Commonwealth Fund, and the healthcare technology company Phreesia, which helps medical practices with patient registration, insurance verification, and payments, and has data on 50,000 providers in all 50 states.

The study was published online by the Commonwealth Fund.

In-person visits are still down 6% from the March 1 baseline. Telemedicine visits – which surged in mid-April to account for some 13%-14% of visits – have subsided to 6% of visits.

Many states reopened businesses and lifted travel restrictions in early September, benefiting medical practices in some areas. But clinicians in some regions are still facing rising COVID-19 cases, as well as “the challenges of keeping patients and clinicians safe while also maintaining revenue,” wrote the report authors.

Some specialties are still hard hit. For the week starting Oct. 4, visits to pulmonologists were off 20% from March 1. Otolaryngology visits were down 17%, and behavioral health visits were down 14%. Cardiology, allergy/immunology, neurology, gastroenterology, and endocrinology also saw drops of 5%-10% from March.

Patients were flocking to dermatologists, however. Visits were up 17% over baseline. Primary care also was popular, with a 13% increase over March 1.

At the height of the pandemic shutdown in late March, Medicare beneficiaries stayed away from doctors the most. Visits dipped 63%, compared with 56% for the commercially insured, and 52% for those on Medicaid. Now, Medicare visits are up 3% over baseline, while Medicaid visits are down 1% and commercially insured visits have risen 1% from March.

The over-65 age group did not have the steepest drop in visits when analyzed by age. Children aged 3-17 years saw the biggest decline at the height of the shutdown. Infants to 5-year-olds have still not returned to prepandemic visit levels. Those visits are off by 10%-18%. The 65-and-older group is up 4% from March.

Larger practices – with more than six clinicians – have seen the biggest rebound, after having had the largest dip in visits, from a decline of 53% in late March to a 14% rise over that baseline. Practices with fewer than five clinicians are still 6% down from the March baseline.
 

Wide variation in telemedicine use

The researchers reported a massive gap in the percentage of various specialties that are using telemedicine. At the top end are behavioral health specialists, where 41% of visits are by telemedicine.

The next-closest specialty is endocrinology, which has 14% of visits via telemedicine, on par with rheumatology, neurology, and gastroenterology. At the low end: ophthalmology, with zero virtual visits; otolaryngology (1%), orthopedics (1%), surgery (2%), and dermatology and ob.gyn., both at 3%.

Smaller practices – with fewer than five clinicians – never adopted telemedicine at the rate of the larger practices. During the mid-April peak, about 10% of the smaller practices were using telemedicine in adult primary care practices, compared with 19% of those primary care practices with more than six clinicians.

The gap persists. Currently, 9% of the larger practices are using telemedicine, compared with 4% of small practices.

One-third of all provider organizations analyzed never-adopted telemedicine. And while use continues, it is now mostly minimal. At the April peak, 35% of the practices with telemedicine reported heavy use – that is, in more than 20% of visits. In September, 9% said they had such heavy use.

It’s an electronic cigarette maker’s dream, but a public health nightmare: The confluence of social isolation and anxiety resulting from the COVID-19 pandemic has the potential to make recent progress against e-cigarette use among teens go up in smoke.

“Stress and worsening mental health issues are well-known predisposing factors for smoking, both in quantity and frequency and in relapse,” said Mary Cataletto, MD, FCCP, clinical professor of pediatrics at New York University Winthrop Hospital, Mineola, during a webinar on e-cigarettes and vaping with asthma in the time of COVID-19, hosted by the Allergy & Asthma Network.

Prior to the pandemic, public health experts appeared to be making inroads into curbing e-cigarette use, according to results of the 2020 National Youth Tobacco Survey, a cross-sectional school-based survey of students from grades 6 to 12.

“In 2020, approximately 1 in 5 high school stu­dents and 1 in 20 middle school students currently used e-cigarettes. By comparison, in 2019, 27.5% of high school students (4.11 million) and 10.5% of middle school students (1.24 million) reported current e-cigarette use,” wrote Brian A. King, PhD, MPH, and colleagues, in an article reporting those results.

“We definitely believe that there was a real decline that occurred up until March. Those data from the National Youth Tobacco Survey were collected prior to youth leaving school settings and prior to the implementation of social distancing and other measures,” said Dr. King, deputy director for research translation in the Office on Smoking and Health within the National Center for Chronic Disease Prevention and Health Promotion at the Centers for Disease Control and Prevention.

“That said, the jury’s still out on what’s going to happen with youth use during the coming year, particularly during the COVID-19 pandemic” he said in an interview.
 

Flavor of the moment

Even though the data through March 2020 showed a distinct decline in e-cigarette use, Dr. King and colleagues found that 3.6 million U.S. adolescents still currently used e-cigarettes in 2020; among current users, more than 80% reported using flavored e-cigarettes.

Dr. Cataletto said in an interview that the 2020 National Youth Tobacco Survey continues to report widespread use of flavored e-cigarettes among young smokers despite Food and Drug Administration admonitions to manufacturers and retailers to remove unauthorized e-cigarettes from the market.

On Jan. 2, 2020, the FDA reported a finalized enforcement policy directed against “unauthorized flavored cartridge-based e-cigarettes that appeal to children, including fruit and mint.”

But as Dr. King and other investigators also mentioned in a separate analysis of e-cigarette unit sales, that enforcement policy applies only to prefilled cartridge e-cigarette products, such as those made by JUUL, and that while sales of mint- or fruit-flavored products of this type declined from September 2014 to May 2020, there was an increase in the sale of disposable e-cigarettes with flavors other than menthol or tobacco.

Dr. Cataletto pointed out that this vaping trend has coincided with the COVID-19 pandemic, noting that, on March 13, 2020, just 2 days after the World Health Organization declared that spread of COVID-19 was officially a pandemic, 16 states closed schools, leaving millions of middle school– and high school–age children at loose ends. She said: “This raised a number of concerns. Would students who used e-cigarettes be at increased risk of COVID-19? Would e-cigarette use increase again due to the social isolation and anxiety as predicted for tobacco smokers? How would access and availability impact e-cigarette use?

“It’s possible that use may go down, because youth may have less access to their typical social sources or other manners in which they obtain the product.” Dr. King said. “Alternatively, youth may have more disposable time on their hands and may be open to other sources of access to these products, and so use could increase.”

There is evidence to suggest that the latter scenario may be true, according to investigators who surveyed more than 1,000 Canadian adolescents about alcohol use, binge drinking, cannabis use, and vaping in the 3 weeks directly before and after social distancing measures took effect.

The investigators found that the frequency of both alcohol and cannabis use increased during social isolation, and that, although about half of respondents reported solitary substance use, 32% reported using substances with peers via technology, and 24% reported using substances face to face, despite social distancing mandates, reported Tara M. Dumas, PhD, from Huron University College, London, Ont.

“These authors suggest that teens who feared loss of friendships during quarantine might be more willing to engage in risky behaviors such as face to face substance use to maintain social status, while solitary substance use was related to both COVID19 fears and depressive symptomatology,” Dr. Cataletto said.
 

E-cigarettes and COVID-19

A recent survey of 4,351 adolescents and young adults in the United States showed that a COVID-19 diagnosis was five times more likely among those who had ever used e-cigarettes, seven times more likely among conventional cigarette and e-cigarette uses, and nearly seven times more likely among those who had used both within the past 30 days .

Perhaps not surprisingly, adolescents and young adults with asthma who also vape may be at especially high risk for COVID-19, but the exact effect may be hard to pin down with current levels of evidence.

“Prior to the pandemic we did see both new-onset asthma and asthma exacerbations in teens who reported either vaping or dual use with tobacco products,” Dr. Cataletto said. “However, numbers were small, were confounded by the bias of subspecialty practice, and the onset of the pandemic, which affected not only face-to-face visits but the opportunity to perform pulmonary function testing for a number of months.”

Dr. King noted: “There is an emerging body of science that does indicate that there could be some respiratory risks related to e-cigarette use, particularly among certain populations. ... That said, there’s no conclusive link between e-cigarette use and specific disease outcomes, which typically requires a robust body of different science conducted in multiple settings.”

He said that e-cigarette vapors contain ultrafine particles and heavy metals that can be inhaled deeply into the lungs, both of which have previously been associated with respiratory risk, including complications from asthma.
 

An ounce of prevention

“When it comes to cessation, we do know that about 50% of youth who are using tobacco products including e-cigarettes, want to quit, and about the same proportion make an effort to quit, so there’s certainly a will there, but we don’t clearly have an evidence-based way,” Dr. King said.

Combinations of behavioral interventions including face-to-face consultations and digital or telephone support can be helpful, Dr. Cataletto said, but both she and Dr. King agree that prevention is the most effective method of reducing e-cigarette use among teens and young adults, including peer support and education efforts.

Asked how she gets her patients to report honestly about their habits, Dr. Cataletto acknowledged that “this is a challenge for many kids. Some are unaware that many of the commercially available e-cigarette products contain nicotine and they are not ‘just vaping flavoring.’ Ongoing education is important, and it is happening in schools, in pediatrician’s offices, at home and in the community.”

Dr. Cataletto and Dr. King reported no relevant conflicts of interest. Dr. Cataletto serves on the editorial advisory board for Chest Physician.

It’s an electronic cigarette maker’s dream, but a public health nightmare: The confluence of social isolation and anxiety resulting from the COVID-19 pandemic has the potential to make recent progress against e-cigarette use among teens go up in smoke.

New developments in treatment of neuromyelitis optica spectrum disorder (NMOSD) have opened up options for disease treatment in pediatric patients, but have led to some uncertainty and confusion as well.

At the2020 CNS-ICNA Conjoint Meeting, held virtually this year, presenters discussed some of the challenges of differential diagnosis and treatment choice in pediatric NMOSD, which is easily confused with multiple sclerosis.

NMOSD used to be considered a monophasic disease restricted to the optic nerve and spinal cord, but is now known to affect other regions of the central nervous system and to relapse in some patients.
 

Diagnosis

The disease is often mediated by antibodies to the aquaporin-4 (AQP-4) water channel, but about 30% of adult patients lack the antibody, and AQP-4 seronegativity is more common in the pediatric population. Another common antibody found in 40%–50% of children with NMOSD targets myelin oligodendrocyte glycoprotein (MOG).

It is important to be aware that false negatives can occur in serology assays, and false positives are common, particularly in ELISA assays, Silvia N. Tenembaum, MD, said during her presentation. For those reasons, serology is not enough for a diagnosis. “Patients should also have compatible symptoms and MRI findings,” said Dr. Tenembaum, director of the pediatric neuroimmunology program at National Pediatric Hospital in Buenos Aires.

According to international consensus criteria, to be diagnosed with NMOSD, AQP-4 seropositive patients should also have at least one core clinical symptom: optic neuritis, acute myelitis, area postrema syndrome, other acute brainstem syndrome, symptomatic narcolepsy or acute diencephalic clinical syndrome, or symptomatic cerebral syndrome. AQP-4 seronegative patients or with unknown status should have at least two core symptoms, one of which must be optic neuritis, acute myelitis, or area postrema syndrome. Both conventional MRI and advanced new techniques are important for achieving differential diagnosis.

The most common symptom in children is optic neuritis, which occurs in 50%-70% of patients. Cerebral syndromes with or without encephalopathy and large tumefactive white matter lesions are also common, according to Dr. Tenembaum.

There are many conditions that mimic the spinal cord and optic nerve symptoms of NMOSD, which must be ruled out. One example is optic myelopathy and vision loss from late-onset biotinylase deficiency. It is critical to rule that out because it is treatable with supplements. Optic neuropathy, papillitis, and papilledema can also resemble NMOSD.

It is critical to achieve an early diagnosis of NMOSD in children, because some MS drugs can worsen NMOSD, according to Thaís Armangue, MD, PhD, head of neuroimmunology at SJD Barcelona Children’s Hospital, who also presented at the session. She pointed out that the MOG antibody, while common in children, is also associated with many demyelinating diseases. Some 50%-60% of children with acute disseminated encephalomyelitis (ADEM) have high titers of MOG antibodies. Although early studies suggested that persistent anti-MOG antibodies were associated with risk of developing MS, more recent studies show it predicts a non-MS disease course, particularly at titers greater than 1:1280, according to Dr. Tenembaum. Persistent anti-MOG antibodies are also associated with relapsing disease, but it is associated with other syndromes besides NMOSD. “The probability is that [MOG antibodies are] useful, but they cannot guide chronic immunotherapy, because even monophasic patients can last maybe 12 months before they become MOG negative, and we cannot wait so many months” to determine treatment course, said Dr. Tenembaum.

For monophasic ADEM or NMOSD, there is no need for chronic treatment. But children with MS and recurrent NMOSD require early chronic immunotherapy because specific therapies have been shown to improve prognosis.
 

Acute treatment

When it comes to acute treatment of NMOSD, the goal is to suppress the inflammatory attack but also to minimize long-term damage and optimize long-term neurological function. “The potential for irreversible injury with an attack is very high, and cumulative disabilities in NMOSD can result directly from attacks,” E. Ann Yeh, MD, director of the Pediatric MS and Neuroinflammatory Disorders Program at the Hospital for Sick Children at the University of Toronto, said during her talk.

IV steroids are generally the first choice, with a preference for methylprednisolone. Pediatric patients that are MOG antibody positive usually respond better and more quickly than do adults, with rapid daily improvements in mobility, vomiting, and eyesight. Dr. Yeh recommends weaning good responders off steroids because AQP-4 positive patients are likely to relapse without a steroid wean, and antibody testing may be unavailable or results may be delayed. The wean can range from 4 weeks to 4-6 months, depending on antibody status, likelihood of AQP-4 positivity, and clinical parameters.

Inadequate responses are usually pretty evident. If there is only light perception by day 4 or 5, or paralyzed patients are nonambulatory and achieve only twitchy movements by that time, second-line therapies should be considered, including therapeutic plasma exchange (TPE) with 5-7 exchanges or intravenous immunoglobulins (IVIg).

Dr. Yeh called for quick treatment. Whatever you do, “please do it sooner rather than later if you think there’s no response [to steroids],” Dr. Yeh said.

TPE is the first choice, according to Dr. Yeh. “There seems to be a fair amount of information that suggests that if you’re having difficulty getting a response to steroids, TPE can make a difference in these patients,” she said. But in some cases TPE may not be available, and IVIg can be attempted first. If it achieves no or only marginal improvement, TPE can be attempted later, but it must be kept in mind that TPE conducted too soon could wash out IVIg. Patients who get much better on IVIg can undergo a steroid wean, and then be evaluated for prophylactic therapy, said Dr. Yeh.

The evidence for IVIg is limited, reflecting the difficulty of studying treatments in rare populations. Still, when TPE is not available and the patient is quite impaired, IVIg makes sense to try. “Absence of evidence does not mean that the therapy doesn’t work, and I don’t think we should throw out the baby with the bath water,” said Dr. Yeh.

Although IVIg treatment is generally well tolerated, there have been a few serious adverse events, such as anaphylactic shock and aseptic meningitis, according to Andrea Savransky, MD, a pediatrician at National Pediatric Hospital in Buenos Aires, who also spoke at the session. “I think it is important to weigh the benefits against the risk,” Dr. Savransky said. She noted that TPE should not be taken lightly. One study showed more complications in pediatric patients than in adult patients, and it must be performed in specialized centers.
 

Emerging treaments

Tanuja Chitnis, MD, director of the Partners Pediatric MS Center at Massachusetts General Hospital, Boston, discussed some of the emerging treatments for pediatric NMOSD. Rituximab has been associated with success in some retrospective studies, but dosing should be personalized. Dr. Chitnis reported that B cells can return before 6 months, so she monitors B cells beginning 2 months after induction, redosing after 4 or 5 months rather than 6 if B cells return.

Nevertheless, relapses can still occur after rituximab therapy. “There is room for additional therapies to address this gap,” said Dr. Chitnis. Three new antibodies have received approval for treatment of NMOSD in adults. These include the complement inhibitor eculizumab, the IL-6 receptor antibody satralizumab, and the anti-CD19 antibody inebilizumab. Phase 3 clinical trials in children have been conducted for eculizumab and are in the planning stage for inebilizumab, and pediatric patients were included in pivotal trials for satralizumab.

Eculizumab treatment resulted in a 94.2% reduction in relapse risk in AQP4-positive adults. Satralizumab showed a 79% reduction in relapse risk among AQP-4 positive subjects with NMOSD or neuromyelitis optica and a 34% reduction in those who were AQP-4 negative. The pediatric subgroup had similar levels of response to adults, though the numbers were too small for a subgroup analysis.

In AQP-4 positive patients, inebilizumab treatment yielded a 77% reduction in relapse rate. In all patients, there was a 73% reduction.

For MOG antibody-positive patients with AQP-4 negative disease, novel therapies are at earlier stages of development. Typical MS therapies such as interferon beta and glatiramer acetate don’t seem to be effective. Some that have shown signs of efficacy include azathioprine, mycophenylate mofetil, rituximab, and IVIg infusion, but the state of the field is not encouraging. “This is an observation now being studied in larger cohorts, but in general I have not found that there’s a very strong response to any of these therapies, possibly with the exception of IVIg,” said Dr. Chitnis.

Dr. Tenembaum has no relevant financial disclosures. Dr. Armangue has received speaking honoraria from Novartis and travel expenses for scientific meetings from Merck, Biogen, and Roche. Dr. Yeh is on the scientific advisory board of Juno Therapeutics and has received research support from Biogen. Dr. Chitnis advises Biogen-Idec, Novartis, and Alexion, serves on clinical trial advisory boards for Novartis and Sanofi Aventis, and has received research support from Verily, EMD Serono, and Novartis. Dr. Savransky has received honoraria from Genzyme de Argentina SA.

Ann Yeh, MD, director of the Pediatric MS and Neuroinflammatory Disorders Program at the Hospital for Sick Children at the University of Toronto, said during her talk.

IV steroids are generally the first choice, with a preference for methylprednisolone. Pediatric patients that are MOG antibody positive usually respond better and more quickly than do adults, with rapid daily improvements in mobility, vomiting, and eyesight. Dr. Yeh recommends weaning good responders off steroids because AQP-4 positive patients are likely to relapse without a steroid wean, and antibody testing may be unavailable or results may be delayed. The wean can range from 4 weeks to 4-6 months, depending on antibody status, likelihood of AQP-4 positivity, and clinical parameters.

Inadequate responses are usually pretty evident. If there is only light perception by day 4 or 5, or paralyzed patients are nonambulatory and achieve only twitchy movements by that time, second-line therapies should be considered, including therapeutic plasma exchange (TPE) with 5-7 exchanges or intravenous immunoglobulins (IVIg).

Dr. Yeh called for quick treatment. Whatever you do, “please do it sooner rather than later if you think there’s no response [to steroids],” Dr. Yeh said.

TPE is the first choice, according to Dr. Yeh. “There seems to be a fair amount of information that suggests that if you’re having difficulty getting a response to steroids, TPE can make a difference in these patients,” she said. But in some cases TPE may not be available, and IVIg can be attempted first. If it achieves no or only marginal improvement, TPE can be attempted later, but it must be kept in mind that TPE conducted too soon could wash out IVIg. Patients who get much better on IVIg can undergo a steroid wean, and then be evaluated for prophylactic therapy, said Dr. Yeh.

The evidence for IVIg is limited, reflecting the difficulty of studying treatments in rare populations. Still, when TPE is not available and the patient is quite impaired, IVIg makes sense to try. “Absence of evidence does not mean that the therapy doesn’t work, and I don’t think we should throw out the baby with the bath water,” said Dr. Yeh.

Although IVIg treatment is generally well tolerated, there have been a few serious adverse events, such as anaphylactic shock and aseptic meningitis, according to Andrea Savransky, MD, a pediatrician at National Pediatric Hospital in Buenos Aires, who also spoke at the session. “I think it is important to weigh the benefits against the risk,” Dr. Savransky said. She noted that TPE should not be taken lightly. One study showed more complications in pediatric patients than in adult patients, and it must be performed in specialized centers.
 

Emerging treaments

Tanuja Chitnis, MD, director of the Partners Pediatric MS Center at Massachusetts General Hospital, Boston, discussed some of the emerging treatments for pediatric NMOSD. Rituximab has been associated with success in some retrospective studies, but dosing should be personalized. Dr. Chitnis reported that B cells can return before 6 months, so she monitors B cells beginning 2 months after induction, redosing after 4 or 5 months rather than 6 if B cells return.

Nevertheless, relapses can still occur after rituximab therapy. “There is room for additional therapies to address this gap,” said Dr. Chitnis. Three new antibodies have received approval for treatment of NMOSD in adults. These include the complement inhibitor eculizumab, the IL-6 receptor antibody satralizumab, and the anti-CD19 antibody inebilizumab. Phase 3 clinical trials in children have been conducted for eculizumab and are in the planning stage for inebilizumab, and pediatric patients were included in pivotal trials for satralizumab.

Eculizumab treatment resulted in a 94.2% reduction in relapse risk in AQP4-positive adults. Satralizumab showed a 79% reduction in relapse risk among AQP-4 positive subjects with NMOSD or neuromyelitis optica and a 34% reduction in those who were AQP-4 negative. The pediatric subgroup had similar levels of response to adults, though the numbers were too small for a subgroup analysis.

In AQP-4 positive patients, inebilizumab treatment yielded a 77% reduction in relapse rate. In all patients, there was a 73% reduction.

For MOG antibody-positive patients with AQP-4 negative disease, novel therapies are at earlier stages of development. Typical MS therapies such as interferon beta and glatiramer acetate don’t seem to be effective. Some that have shown signs of efficacy include azathioprine, mycophenylate mofetil, rituximab, and IVIg infusion, but the state of the field is not encouraging. “This is an observation now being studied in larger cohorts, but in general I have not found that there’s a very strong response to any of these therapies, possibly with the exception of IVIg,” said Dr. Chitnis.

New developments in treatment of neuromyelitis optica spectrum disorder (NMOSD) have opened up options for disease treatment in pediatric patients, but have led to some uncertainty and confusion as well.

At the2020 CNS-ICNA Conjoint Meeting, held virtually this year, presenters discussed some of the challenges of differential diagnosis and treatment choice in pediatric NMOSD, which is easily confused with multiple sclerosis.

NMOSD used to be considered a monophasic disease restricted to the optic nerve and spinal cord, but is now known to affect other regions of the central nervous system and to relapse in some patients.
 

Diagnosis

The disease is often mediated by antibodies to the aquaporin-4 (AQP-4) water channel, but about 30% of adult patients lack the antibody, and AQP-4 seronegativity is more common in the pediatric population. Another common antibody found in 40%–50% of children with NMOSD targets myelin oligodendrocyte glycoprotein (MOG).

It is important to be aware that false negatives can occur in serology assays, and false positives are common, particularly in ELISA assays, Silvia N. Tenembaum, MD, said during her presentation. For those reasons, serology is not enough for a diagnosis. “Patients should also have compatible symptoms and MRI findings,” said Dr. Tenembaum, director of the pediatric neuroimmunology program at National Pediatric Hospital in Buenos Aires.

According to international consensus criteria, to be diagnosed with NMOSD, AQP-4 seropositive patients should also have at least one core clinical symptom: optic neuritis, acute myelitis, area postrema syndrome, other acute brainstem syndrome, symptomatic narcolepsy or acute diencephalic clinical syndrome, or symptomatic cerebral syndrome. AQP-4 seronegative patients or with unknown status should have at least two core symptoms, one of which must be optic neuritis, acute myelitis, or area postrema syndrome. Both conventional MRI and advanced new techniques are important for achieving differential diagnosis.

The most common symptom in children is optic neuritis, which occurs in 50%-70% of patients. Cerebral syndromes with or without encephalopathy and large tumefactive white matter lesions are also common, according to Dr. Tenembaum.

There are many conditions that mimic the spinal cord and optic nerve symptoms of NMOSD, which must be ruled out. One example is optic myelopathy and vision loss from late-onset biotinylase deficiency. It is critical to rule that out because it is treatable with supplements. Optic neuropathy, papillitis, and papilledema can also resemble NMOSD.

It is critical to achieve an early diagnosis of NMOSD in children, because some MS drugs can worsen NMOSD, according to Thaís Armangue, MD, PhD, head of neuroimmunology at SJD Barcelona Children’s Hospital, who also presented at the session. She pointed out that the MOG antibody, while common in children, is also associated with many demyelinating diseases. Some 50%-60% of children with acute disseminated encephalomyelitis (ADEM) have high titers of MOG antibodies. Although early studies suggested that persistent anti-MOG antibodies were associated with risk of developing MS, more recent studies show it predicts a non-MS disease course, particularly at titers greater than 1:1280, according to Dr. Tenembaum. Persistent anti-MOG antibodies are also associated with relapsing disease, but it is associated with other syndromes besides NMOSD. “The probability is that [MOG antibodies are] useful, but they cannot guide chronic immunotherapy, because even monophasic patients can last maybe 12 months before they become MOG negative, and we cannot wait so many months” to determine treatment course, said Dr. Tenembaum.

For monophasic ADEM or NMOSD, there is no need for chronic treatment. But children with MS and recurrent NMOSD require early chronic immunotherapy because specific therapies have been shown to improve prognosis.

After almost 2 decades of progress, the global state of measles vaccination and measles mortality is deteriorating. Vaccine hesitancy, natural disasters, geopolitical disruptions, and most recently the COVID-19 pandemic have combined to undermine efforts, which had aimed to eradicate measles by this year.

One of the most serious concerns of measles infection is its long-term neurological complications, including the fatal subacute sclerosing panencephalitis (SSPE) and measles inclusion-body encephalitis (MIBE), which is usually seen in immune deficient children. Although some efforts are being made to determine which patients might be most vulnerable to these outcomes, and to treat them, the best approach is still prevention and vaccination, according to Banu Anlar, MD, of Hacettepe University, Ankara, Turkey, who spoke during a session at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year.

Worldwide vaccination strategies have slipped in recent years, leading to upticks in measles cases and vaccination rates. As a result, in 2018 the World Health Organization postponed its goal of eliminating measles by 2020. Future eradication goals will likely need to be modified, according to Anaita Udwadia Hegde MD, a pediatric neurologist in Mumbai, India, who also presented at the session.

After measles deaths dropped 74% between 2000 and 2010, coinciding with widespread increases in vaccination, the WHO felt emboldened to deal the disease a knockout blow. In 2010, it held a Global Technical Consultation to determine the feasibility of an eradication campaign, which concluded it should be possible by 2020. Several characteristics of measles made that a reasonable goal: It is passed only among humans, with no known animal reservoir; natural infection grants lifelong immunity; there is only one serotype; the virus is genetically stable; the vaccine is safe and leads to 95%-97% seroconversion after two doses, which provides long-term protection against known genotypes; the disease is easily recognized and tested for; and it had been successfully eliminated already in some regions of the world.

As of 2017, analyses showed that the vaccination program saved the lives of about 1.5 million children. That was a cause for celebration, but the goal of eradication has remained elusive. Vaccination rates have trailed targets. In 2018, UNICEF and WHO estimated that 86% of children globally received the first measles vaccine, unchanged from 2010 and below the goal of 95%. Only 69% of children received the second dose, below the goal of 80%. Four countries in Europe lost their measles elimination status in 2018.

Other attempts to eradicate diseases have met with mixed results. The only full success was smallpox, eliminated in 1977. Similar efforts with polio, malaria, guinea worm, and now measles have all come up short. Those failures could complicate future efforts because global agencies and donors may be leery of past failures because of potential harm to their reputations, according to Dr. Hegde.

Such programs require sustained financial commitment and political support as well as local trust. Nevertheless, they must continue for ethical reasons, said Dr. Hegde, but also for economic ones: Every $1 spent on vaccination programs saves $58 in future costs in low- and middle-income countries. Missed childhood vaccination also results in future vulnerable teenagers and young adults, and these populations are much harder to reach and can drive large outbreaks.

Several factors are contributing to the global regression in vaccine coverage, according to Kristen Feemster, MD, MPH, a pediatric infectious disease physician and the global director of medical affairs at Merck. Globalization has enabled the spread of the disease. Most cases in the United States are imported by travelers to countries where the disease is endemic. “Measles can happen anywhere in the world, and when it does it can travel and spread. If you have an unvaccinated traveler who is exposed to measles abroad, they can return home and spread it to anyone else who is unvaccinated or not otherwise immune. When we see cases they’ve been sporadic, but if you return to a community where immunization rates are low, you have the potential for more sustained spread,” Dr. Feemster said during her presentation.

Why are so many travelers unvaccinated? A key reason is that vaccine hesitance is growing. Most affected individuals involved in outbreaks are unvaccinated, usually by choice rather than for medical reasons. Concerns continue over the measles vaccine and autism, growing out of the debunked studies of Andrew Wakefield. In one example, a Somali community in Minnesota experienced a higher than usual number of autism cases and parents sought reasons to explain it. They discovered the supposed connection between vaccination and autism, and Wakefield himself met with a group of them. The result was a drop in vaccination and, in 2011 and 2017, sizable measles outbreaks.

2020 has of course brought a fresh challenge to measles vaccine with the COVID-19 pandemic, which has reduced access to health care and shifted scientific and health care interest away from measles and other vaccine-preventable diseases. On the positive side, social distancing, mask wearing, and restricted movement are likely reducing exposure to measles, but reduced vaccination rates are likely to result in future outbreaks. “There’s been a significant decrease in rates for routine immunizations globally, so there’s a potential for yet another resurgence of measles and other vaccine-preventable diseases,” said Dr. Feemster.

Neither diabetes per se nor hyperglycemia appear to impair the antibody response to SARS-CoV-2, suggesting that a COVID-19 vaccine would be just as effective in people with diabetes as in those without, new research finds.

Results from a study involving 480 patients with confirmed COVID-19 seen at an Italian hospital between February 25 and April 19 were published online October 8 in Diabetologia by Vito Lampasona, MD, and colleagues.

Antibody responses against multiple SARS-CoV-2 antigens among the 27% of patients with COVID-19 and diabetes (preexisting and newly diagnosed) were similar with regard to timing, titers, and classes to those of patients with COVID-19 and without diabetes, and the results did not differ by glucose levels.

Moreover, positivity for immunoglobulin G (IgG) against the SARS-CoV-2 spike receptor-binding domain (RBD) was associated with improved survival regardless of diabetes status.

And as previously shown, high blood glucose levels were strongly associated with greater COVID-19 mortality even in those without diabetes.

This is the first study of the immunologic humoral response against SARS-CoV-2 in patients with hyperglycemia, the authors say.

“The immunological response to a future SARS-CoV-2 vaccine will be assessed when the vaccine becomes available. However, our data allow a cautious optimism regarding effective immunization in individuals with diabetes, as well as in the general population,” wrote Dr. Lampasona of San Raffaele Diabetes Research Institute, IRCCS Ospedale San Raffaele in Milan, and colleagues.
 

Diabetes and hyperglycemia worsen COVID-19 outcomes

The investigators analyzed the presence of three types of antibody to multiple SARS-CoV-2 antigens in 509 participants: IgG, which is evidence of past infection; IgM, which indicates more recent or current infection; and IgA, which is involved in the mucosal immune response, for example, in the nose where the virus enters the body.

Overall, 452 (88.8%) patients were hospitalized, 79 (15.5%) patients were admitted to intensive care, and 93 (18.3%) patients died during follow-up.

Of the 139 patients with diabetes, 90 (17.7% of the study cohort) already had a diagnosis of diabetes, and 49 (9.6%) were newly diagnosed.

Those with diabetes were older, had a higher body mass index (BMI), and were more likely to have cardiovascular comorbidities, hypertension, and chronic kidney disease. As has been previously reported for diabetes and COVID-19, diabetes was also associated with increased levels of inflammatory biomarkers, hypercoagulopathy, leukocytosis, and neutrophilia.

In multivariate analysis, diabetes status (hazard ratio, 2.32; P = .001), mean fasting plasma glucose (P < .001), and glucose variability (P = .002) were all independently associated with increased mortality and ICU admission. And fasting plasma glucose was associated with increased mortality risk even among those without diabetes (P < .001).
 

Antibody response similar in patients with and without diabetes

The humoral response against SARS-CoV-2 in patients with diabetes was present and superimposable in terms of timing and antibody titers to that of patients without diabetes, with marginal differences, and was not influenced by glucose levels.

After adjustment for sex, age, and diabetes status and stratification by symptom duration at time of sampling, the development of SARS-CoV-2 RBD IgG antibodies was associated with improved survival, with an HR for time to death of 0.4 (P = .002).

“Of the measured antibody responses, positivity for IgG against the SARS-CoV-2 spike RBD was predictive of survival rate, both in the presence or absence of diabetes,” the authors stressed, with similar HRs for those with diabetes (0.37; P = .013) and without diabetes (0.43; P = .038).

These data confirm “the relevance for patient survival rate of the specific antigen response against spike RBD even in the presence of diabetes, and it underlines how the mechanism explaining the worse clinical outcome in patients with diabetes is unrelated to the antibody response,” they explain.

They added, “This, together with evidence that increased blood glucose levels do predict a poor prognosis even in nondiabetic individuals and the association with increased levels of inflammatory biomarkers and hypercoagulopathy, as well as leukocytosis and neutrophilia, support the speculation that glucose per se could be an independent biological negative factor, acting as a direct regulator of innate immunity.”

“The observed increased severity and mortality risk of COVID-19 pneumonia in patients with hyperglycemia was not the result of an impaired humoral response against SARS-CoV-2.”

“RBD IgG positivity was associated with a remarkable protective effect, allowing for a cautious optimism about the efficacy of future vaccines against SARS-COV-2 in people with diabetes,” they reiterated.

Neither diabetes per se nor hyperglycemia appear to impair the antibody response to SARS-CoV-2, suggesting that a COVID-19 vaccine would be just as effective in people with diabetes as in those without, new research finds.

Results from a study involving 480 patients with confirmed COVID-19 seen at an Italian hospital between February 25 and April 19 were published online October 8 in Diabetologia by Vito Lampasona, MD, and colleagues.

Antibody responses against multiple SARS-CoV-2 antigens among the 27% of patients with COVID-19 and diabetes (preexisting and newly diagnosed) were similar with regard to timing, titers, and classes to those of patients with COVID-19 and without diabetes, and the results did not differ by glucose levels.

Moreover, positivity for immunoglobulin G (IgG) against the SARS-CoV-2 spike receptor-binding domain (RBD) was associated with improved survival regardless of diabetes status.

And as previously shown, high blood glucose levels were strongly associated with greater COVID-19 mortality even in those without diabetes.

This is the first study of the immunologic humoral response against SARS-CoV-2 in patients with hyperglycemia, the authors say.

“The immunological response to a future SARS-CoV-2 vaccine will be assessed when the vaccine becomes available. However, our data allow a cautious optimism regarding effective immunization in individuals with diabetes, as well as in the general population,” wrote Dr. Lampasona of San Raffaele Diabetes Research Institute, IRCCS Ospedale San Raffaele in Milan, and colleagues.
 

Diabetes and hyperglycemia worsen COVID-19 outcomes

The investigators analyzed the presence of three types of antibody to multiple SARS-CoV-2 antigens in 509 participants: IgG, which is evidence of past infection; IgM, which indicates more recent or current infection; and IgA, which is involved in the mucosal immune response, for example, in the nose where the virus enters the body.

Overall, 452 (88.8%) patients were hospitalized, 79 (15.5%) patients were admitted to intensive care, and 93 (18.3%) patients died during follow-up.

Of the 139 patients with diabetes, 90 (17.7% of the study cohort) already had a diagnosis of diabetes, and 49 (9.6%) were newly diagnosed.

Those with diabetes were older, had a higher body mass index (BMI), and were more likely to have cardiovascular comorbidities, hypertension, and chronic kidney disease. As has been previously reported for diabetes and COVID-19, diabetes was also associated with increased levels of inflammatory biomarkers, hypercoagulopathy, leukocytosis, and neutrophilia.

In multivariate analysis, diabetes status (hazard ratio, 2.32; P = .001), mean fasting plasma glucose (P < .001), and glucose variability (P = .002) were all independently associated with increased mortality and ICU admission. And fasting plasma glucose was associated with increased mortality risk even among those without diabetes (P < .001).
 

Antibody response similar in patients with and without diabetes

The humoral response against SARS-CoV-2 in patients with diabetes was present and superimposable in terms of timing and antibody titers to that of patients without diabetes, with marginal differences, and was not influenced by glucose levels.

After adjustment for sex, age, and diabetes status and stratification by symptom duration at time of sampling, the development of SARS-CoV-2 RBD IgG antibodies was associated with improved survival, with an HR for time to death of 0.4 (P = .002).

“Of the measured antibody responses, positivity for IgG against the SARS-CoV-2 spike RBD was predictive of survival rate, both in the presence or absence of diabetes,” the authors stressed, with similar HRs for those with diabetes (0.37; P = .013) and without diabetes (0.43; P = .038).
