Pandemic necessitates new strategies to treat migraine
Patients with migraine who are unable to continue preventive procedures such as onabotulinumtoxinA injections during the COVID-19 pandemic may be at risk of worsening migraine, according to an article published March 30 in Headache. To address this scenario, including monoclonal antibodies against calcitonin gene-related peptide (CGRP) or the CGRP receptor, the authors said.
“This is a particularly vulnerable time for individuals with migraine and other disabling headache disorders, with many physical and mental stressors, increased anxiety, and changes in daily routine which may serve as triggering factors for worsening headache,” said lead author Christina L. Szperka, MD, director of the pediatric headache program at Children’s Hospital of Philadelphia, and colleagues.
Acute treatment
The authors described potential treatment regimens based on their experience as headache specialists and the experiences of their colleagues. For acute therapy options, NSAIDs, triptans, and neuroleptics may be used in combination when needed. Medications within the same drug category should not be combined, however, and triptans, dihydroergotamine, and lasmiditan should not be coadministered within 24 hours. Since the 2015 American Headache Society guideline for the acute treatment of migraine, the Food and Drug Administration has approved additional acute migraine medications, including ubrogepant, rimegepant, and lasmiditan, the authors said. The agency also cleared several neuromodulation devices for the acute treatment of migraine.
Although few drugs have been studied as treatments for unusually prolonged severe headaches, headache doctors often recommend NSAIDs before patients seek care at an emergency department or infusion center, the authors said. NSAID options include indomethacin, ketorolac, naproxen, nabumetone, diclofenac, and mefenamic acid. Neuroleptics also may be used. “Long-acting triptan medications can be used as bridge therapies, as is often done in the treatment of menstrually related migraine or in the treatment of medication overuse headache,” they said. “We propose a similar strategy can be trialed as a therapeutic option for refractory or persistent migraine.”
The authors also described the use of antiepileptics and corticosteroids, as well as drugs that may treat specific symptoms, such as difficulty sleeping (hydroxyzine or amitriptyline), neck or muscle pain (tizanidine), and aura with migraine (magnesium). Clinicians should avoid the use of opioids and butalbital, they said.
Preventive treatment
“While the injection of onabotulinumtoxinA is an effective treatment for chronic migraine, the procedure can put the patient and the provider at higher risk of COVID-19 given the close contact encounter,” wrote Dr. Szperka and colleagues. “We believe that other migraine preventive treatments should be utilized first when possible.” Since the publication of a guideline on preventive migraine therapies in 2012, the FDA has approved additional preventive therapies, including the anti-CGRP monoclonal antibodies erenumab‐aooe, galcanezumab‐gnlm, fremanezumab‐vfrm, and eptinezumab‐jjmr. “The first three are intended for self‐injection at home, with detailed instructions available for each product on its website,” they said.
Among angiotensin‐converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), candesartan has evidence of efficacy and tolerability in migraine prevention. Lisinopril has been considered possibly effective. “There has been recent concern in the media about the possibility of these medications interfering with the body’s response to COVID‐19,” the authors said, although this theoretical concern was not based on experimental or clinical data. “For patients in need of a new preventive therapy, the potential for benefit with an ACE/ARB must be weighed against the theoretical increased risk of infection.”
In addition, studies indicate that melatonin may prevent migraine with few side effects and that zonisamide may be effective in patients who have an inadequate response to or experience side effects with topiramate.
Policy changes and telehealth options
Effectively treating patients with migraine during the pandemic requires policy changes, according to the authors. “Migraine preventive prior authorization restrictions need to be lifted for evidence‐based, FDA‐approved therapies; patients need to be able to access these medications quickly and easily. Patients should not be required to fail older medications,” they said. “Similarly, in order to permit the transition of patients from onabotulinumtoxinA to anti‐CGRP [monoclonal antibodies], insurers should remove the prohibition against simultaneous coverage of these drug classes.” Insurers also should loosen restrictions on the off-label use of acute and preventive medication for adolescents, Dr. Szperka and coauthors suggest.
“In the era of COVID‐19, telehealth has become an essential modality for most headache specialists, given the need for providers to take significant precautions for both their patients and themselves, limiting touch or close contact,” they said. Patients with headache may warrant additional screening for COVID-19 as well. “As headache has been reported as an early symptom of COVID‐19, patients with worsening or new onset severe headache should be reviewed for exposure risk and any other symptoms which may be consistent with COVID‐19 infection,” the authors said.
There was no direct funding for the report. Dr. Szperka and a coauthor receive salary support from the National Institutes of Health. Dr. Szperka also has received grant support from Pfizer, and her institution has received compensation for her consulting work for Allergan. Several coauthors disclosed consulting and serving on speakers’ bureaus for and receiving research support from various pharmaceutical companies.

COVID-19 less severe in children, yet questions for pediatricians remain
COVID-19 is less severe in children, compared with adults, early data suggest. “Yet many questions remain, especially regarding the effects on children with special health care needs,” according to a viewpoint recently published in JAMA Pediatrics.
The COVID-19 pandemic also raises questions about clinic visits for healthy children in communities with widespread transmission and about the unintended effects of school closures and other measures aimed at slowing the spread of the disease, wrote Sonja A. Rasmussen, MD, and Lindsay A. Thompson, MD, both of the University of Florida, Gainesville.
In communities with widespread outbreaks, telephone triage and expanded use of telehealth may be needed to limit nonurgent clinic visits, they suggested.
“Community mitigation interventions, such as school closures, cancellation of mass gatherings, and closure of public places are appropriate” in places with widespread transmission, Dr. Rasmussen and Dr. Thompson wrote. “If these measures are required, pediatricians need to advocate to alleviate unintended consequences or inadvertent expansion of health disparities on children, such as by finding ways to maintain nutrition for those who depend on school lunches and provide online mental health services for stress management for families whose routines might be severely interrupted for an extended period of time.”
Continued preventive care for infants and vaccinations for younger children may be warranted, they wrote.
Clinical course
Overall, children have experienced lower-than-expected rates of COVID-19 disease, and deaths in this population appear to be rare, Dr. Rasmussen and Dr. Thompson wrote.
Common symptoms of COVID-19 in adults include fever, cough, myalgia, shortness of breath, headache, and diarrhea, and children have similar manifestations. In adults, older age and underlying illness increase the risk of severe disease. There has not been convincing evidence of intrauterine transmission of COVID-19, and whether breastfeeding can transmit the virus is unknown, they noted.
An analysis of more than 72,000 cases from China found that 1.2% were in patients aged 10-19 years, and 0.9% were in patients younger than 10 years. One death occurred in the adolescent age range. A separate analysis of 2,143 confirmed and suspected pediatric cases in China indicated that infants were at higher risk of severe disease (11%), compared with older children – 4% for those aged 11-15 years, and 3% in those 16 years and older.
There is less data available about the clinical course of COVID-19 in children in the United States, the authors noted. But among more than 4,000 patients with COVID-19 in the United States through March 16, no ICU admissions or deaths were reported for patients aged younger than 19 years (MMWR Morb Mortal Wkly Rep. 2020 Mar 26;69[12]:343-6).
Still, researchers have suggested that children with underlying illness may be at greater risk of COVID-19. In a study of 20 children with COVID-19 in China, 7 of the patients had a history of congenital or acquired disease, potentially indicating that they were more susceptible to the virus (Pediatr Pulmonol. 2020 Mar 5. doi: 10.1002/ppul.24718). Chest CT consolidations with surrounding halo sign was evident in half of the patients, and procalcitonin elevation was seen in 80% of the children; these were signs common in children, but not in adults with COVID-19.
“About 10% of children in the U.S. have asthma; many children live with other pulmonary, cardiac, neuromuscular, or genetic diseases that affect their ability to handle respiratory disease, and other children are immunosuppressed because of illness or its treatment,” Dr. Rasmussen and Dr. Thompson wrote. “It is possible that these children will experience COVID-19 differently than counterparts of the same ages who are healthy.”
The authors reported that they had no financial disclosures.

CBT by phone reduces depression in Parkinson’s disease
, according to trial results published in Neurology. The treatment’s effect on depression is “moderated by the reduction of negative thoughts,” the target of the intervention, the researchers said.
Telephone-based CBT may be a convenient option for patients, said lead study author Roseanne D. Dobkin, PhD, of the department of psychiatry at Rutgers Robert Wood Johnson Medical School in Piscataway, N.J., and the VA New Jersey Health Care System in Lyons. “A notable proportion of people with Parkinson’s [disease] do not receive the much needed mental health treatment to facilitate proactive coping with the daily challenges superimposed by their medical condition,” Dr. Dobkin said in a news release. “This study suggests that the effects of the [CBT] last long beyond when the treatment stopped and can be used alongside standard neurological care.”
An undertreated problem
Although depression affects about half of patients with Parkinson’s disease and is associated with physical and cognitive decline, it often goes overlooked and undertreated, the study authors said. Data about the efficacy and tolerability of antidepressants are mixed. CBT holds promise for reducing depression in Parkinson’s disease, prior research suggests, but patients may have limited access to in-person sessions because of physical and geographic barriers.
To assess the efficacy of telephone-based CBT for depression in Parkinson’s disease, compared with community-based treatment as usual, Dr. Dobkin and colleagues conducted a randomized controlled trial. Their study included 72 patients with Parkinson’s disease at an academic medical center. Participants had a depressive disorder, were between aged 35 and 85 years, had stable Parkinson’s disease and mental health treatment for at least 6 weeks, and had a family member or friend willing to participate in the study. The investigators excluded patients with possible dementia or marked cognitive impairment and active suicidal plans or intent.
Participants were randomly assigned to receive usual care plus telephone-based CBT or usual care only. Patients taking antidepressants were evenly divided between the groups.
Telephone-based CBT consisted of weekly 1-hour sessions for 10 weeks. During 6 months of follow-up, patients could receive one session per month if desired. The CBT “targeted negative thoughts (e.g., ‘I have no control’; ‘I am helpless’) and behaviors (e.g., avoidance, excessive worry, lack of exercise),” the investigators said. In addition, therapists trained patients’ care partners by telephone to help patients between sessions. Treatment as usual was defined by patients’ health care teams. For most participants in both groups, treatment as usual included taking antidepressant medication or receiving psychotherapy in the community.
Change in Hamilton Depression Rating Scale (HAM-D) score was the primary outcome. Secondary outcomes included whether patients considered their depression much improved and improvements in depression severity (as measured by the Beck Depression Inventory [BDI]), anxiety (as measured by the Hamilton Anxiety Rating Scale [HAM-A]), and quality of life. The researchers also assessed negative thinking using the Inference Questionnaire. Blinded raters assessed outcomes.
Sustained improvements
Thirty-seven patients were randomized to receive telephone-based CBT, and 35 were randomized to treatment as usual. Overall, 70% were taking antidepressants, and 14% continued receiving psychotherapy from community providers of their choice during the trial. Participants’ average age was 65 years, and 51% were female.
Post treatment, mean improvement in HAM-D score from baseline was 6.53 points in the telephone-based CBT group, compared with −0.27 points in the control group. “Effects at the end of treatment were maintained at 6-month follow-up,” the researchers reported.
About 40% of patients in the CBT group reported that their depression was much improved or very much improved, compared with none of the patients in the control group. Responders had mild to minimal symptomatology on the HAM-D, which indicates that the changes were clinically significant, the authors said.
Secondary outcomes also favored telephone-based CBT. “The intervention was feasible and highly acceptable, yielding an 88% retention rate over the 9-month trial,” Dr. Dobkin and colleagues said.
Compared with other control conditions, treatment-as-usual controls may enhance the effect size of an intervention, the authors noted. In addition, factors such as therapeutic relationship, time, and attention likely contribute to psychotherapy outcomes.
Success may hinge on cognitive ability
“The success of this trial highlights the need for further efficacy studies targeting neuropsychiatric manifestations of [Parkinson’s disease] and adds urgency to the discussion over policies regarding access to tele–mental health, especially for vulnerable populations with limited access to in-person mental health services,” Gregory M. Pontone, MD, and Kelly A. Mills, MD, wrote in an accompanying editorial. Dr. Pontone and Dr. Mills are affiliated with Johns Hopkins University in Baltimore.
“Only rudimentary evidence” exists to guide the treatment of depression in patients with Parkinson’s disease, the editorialists said. “Patient preference and tolerability suggest that nonpharmacologic therapies, such as CBT, are preferred as first-line treatment. Yet access to qualified CBT practitioners, especially those with a clinical knowledge of [Parkinson’s disease], is limited.”
Despite its advantages and the encouraging results, CBT may have important limitations as well, they said. Patients require a certain degree of cognitive ability to benefit from CBT, and the prevalence of dementia among patients with Parkinson’s disease is about 30%.
Nevertheless, the trial provided evidence of target engagement. “Though caveats include the single-blind design and potential confounding by time spent with patient and caregiver, the authors demonstrated that improvement was mediated by the mechanism of CBT – a reduction in negative thinking.”
The trial was funded by the Michael J. Fox Foundation for Parkinson’s Research and the Parkinson’s Alliance (Parkinson’s Unity Walk). Dr. Mills disclosed a patent pending for a system for phase-dependent cortical brain stimulation, National Institutes of Health funding, pending funding from the Michael J. Fox Foundation, and commercial research support from Global Kinetics Corporation. Dr. Pontone is a consultant for Acadia Pharmaceuticals.

Although depression affects about half of patients with Parkinson’s disease and is associated with physical and cognitive decline, it often goes overlooked and undertreated, the study authors said. Data about the efficacy and tolerability of antidepressants are mixed. CBT holds promise for reducing depression in Parkinson’s disease, prior research suggests, but patients may have limited access to in-person sessions because of physical and geographic barriers.
To assess the efficacy of telephone-based CBT for depression in Parkinson’s disease, compared with community-based treatment as usual, Dr. Dobkin and colleagues conducted a randomized controlled trial. Their study included 72 patients with Parkinson’s disease at an academic medical center. Participants had a depressive disorder, were between aged 35 and 85 years, had stable Parkinson’s disease and mental health treatment for at least 6 weeks, and had a family member or friend willing to participate in the study. The investigators excluded patients with possible dementia or marked cognitive impairment and active suicidal plans or intent.
Participants were randomly assigned to receive usual care plus telephone-based CBT or usual care only. Patients taking antidepressants were evenly divided between the groups.
Telephone-based CBT consisted of weekly 1-hour sessions for 10 weeks. During 6 months of follow-up, patients could receive one session per month if desired. The CBT “targeted negative thoughts (e.g., ‘I have no control’; ‘I am helpless’) and behaviors (e.g., avoidance, excessive worry, lack of exercise),” the investigators said. In addition, therapists trained patients’ care partners by telephone to help patients between sessions. Treatment as usual was defined by patients’ health care teams. For most participants in both groups, treatment as usual included taking antidepressant medication or receiving psychotherapy in the community.
Change in Hamilton Depression Rating Scale (HAM-D) score was the primary outcome. Secondary outcomes included whether patients considered their depression much improved and improvements in depression severity (as measured by the Beck Depression Inventory [BDI]), anxiety (as measured by the Hamilton Anxiety Rating Scale [HAM-A]), and quality of life. The researchers also assessed negative thinking using the Inference Questionnaire. Blinded raters assessed outcomes.
Sustained improvements
Thirty-seven patients were randomized to receive telephone-based CBT, and 35 were randomized to treatment as usual. Overall, 70% were taking antidepressants, and 14% continued receiving psychotherapy from community providers of their choice during the trial. Participants’ average age was 65 years, and 51% were female.
Post treatment, mean improvement in HAM-D score from baseline was 6.53 points in the telephone-based CBT group, compared with −0.27 points in the control group. “Effects at the end of treatment were maintained at 6-month follow-up,” the researchers reported.
About 40% of patients in the CBT group reported that their depression was much improved or very much improved, compared with none of the patients in the control group. Responders had mild to minimal symptomatology on the HAM-D, which indicates that the changes were clinically significant, the authors said.
Secondary outcomes also favored telephone-based CBT. “The intervention was feasible and highly acceptable, yielding an 88% retention rate over the 9-month trial,” Dr. Dobkin and colleagues said.
Compared with other control conditions, treatment-as-usual controls may enhance the effect size of an intervention, the authors noted. In addition, factors such as therapeutic relationship, time, and attention likely contribute to psychotherapy outcomes.
Success may hinge on cognitive ability
“The success of this trial highlights the need for further efficacy studies targeting neuropsychiatric manifestations of [Parkinson’s disease] and adds urgency to the discussion over policies regarding access to tele–mental health, especially for vulnerable populations with limited access to in-person mental health services,” Gregory M. Pontone, MD, and Kelly A. Mills, MD, wrote in an accompanying editorial. Dr. Pontone and Dr. Mills are affiliated with Johns Hopkins University in Baltimore.
“Only rudimentary evidence” exists to guide the treatment of depression in patients with Parkinson’s disease, the editorialists said. “Patient preference and tolerability suggest that nonpharmacologic therapies, such as CBT, are preferred as first-line treatment. Yet access to qualified CBT practitioners, especially those with a clinical knowledge of [Parkinson’s disease], is limited.”
Despite its advantages and the encouraging results, CBT may have important limitations as well, they said. Patients require a certain degree of cognitive ability to benefit from CBT, and the prevalence of dementia among patients with Parkinson’s disease is about 30%.
Nevertheless, the trial provided evidence of target engagement. “Though caveats include the single-blind design and potential confounding by time spent with patient and caregiver, the authors demonstrated that improvement was mediated by the mechanism of CBT – a reduction in negative thinking.”
The trial was funded by the Michael J. Fox Foundation for Parkinson’s Research and the Parkinson’s Alliance (Parkinson’s Unity Walk). Dr. Mills disclosed a patent pending for a system for phase-dependent cortical brain stimulation, National Institutes of Health funding, pending funding from the Michael J. Fox Foundation, and commercial research support from Global Kinetics Corporation. Dr. Pontone is a consultant for Acadia Pharmaceuticals.

FROM NEUROLOGY
Neurologists navigate unknown territory during COVID-19 pandemic
Neurologic disorders are among the “underlying medical conditions that may increase the risk of serious COVID-19 for individuals of any age,” according to the Centers for Disease Control and Prevention.
Potentially relevant drug interactions, how immunosuppressive medications may influence the risk of COVID-19, and neurologic diseases that may be associated with greater risk are among the questions that experts and groups have addressed.
According to the CDC, neurologic conditions that may heighten the risk of severe COVID-19 include “disorders of the brain, spinal cord, peripheral nerve, and muscle such as cerebral palsy, epilepsy (seizure disorders), stroke, intellectual disability, moderate to severe developmental delay, muscular dystrophy, or spinal cord injury.” Many patients, however, may not have substantially increased risks, neurologists suggest.
“Patients with conditions that do not affect their swallowing or breathing muscles and in whom the immune system is working normally are not considered to be at increased risk from COVID-19,” according to March 26 guidance from the Association of British Neurologists (ABN). “Milder or moderate forms of many of the commoner neurological disorders, such as Parkinson’s disease, multiple sclerosis, epilepsy, are not currently considered to confer increased risk, so long as the breathing and swallowing muscles are functioning well.”
Neurologists should tailor treatment decisions to individual patients, according to the ABN. “Although some neurological conditions or treatments increase the risk of complicated COVID-19, most patients in these groups will overcome the infection,” the association noted.
Interactions with potential COVID-19 treatments
Standard drugs in neurology may interact with potential COVID-19 treatments. For example, “preliminary experience suggests that there is a possible benefit from hydroxychloroquine and azithromycin treatment in COVID-19 infection,” but either of those drugs “may lead to a deterioration in myasthenia gravis,” the ABN notes. “Doctors will have to balance the risks from myasthenia and COVID-19 on a case-by-case basis.” The Liverpool Drug Interactions Group has published tables that describe interactions between potential COVID-19 treatments and anticonvulsants, analgesics, immunosuppressants, and other medication classes.
Many muscle diseases and neuromuscular junction diseases may entail higher risks of complicated COVID-19, the ABN suggested. For patients on immunotherapy, the medication may be a more important consideration for COVID-19 than the underlying disease. Other comorbidities such as hypertension, renal impairment, neutropenia, lymphopenia, liver disease, diabetes mellitus, ischemic heart disease, and lung disease may be important factors, according to the association.
Seizures may not worsen
After the CDC added epilepsy to its list of conditions that entail higher risk of severe COVID-19, M. Scott Perry, MD, medical director of neurology at Cook Children’s Medical Center in Fort Worth, Tex., commented on Twitter that “most healthy people with controlled epilepsy [are] probably at no more risk than others.”
“Those treated with steroids or other immunosuppressive drugs are likely higher risk,” Dr. Perry said. “Likewise, patients with other medical comorbidities such as muscle weakness, swallowing or breathing problems, and other complex cases of epilepsy are likely higher risk. Regardless: be responsible, avoid crowds, wash your hands, avoid sick contacts.”
Doctors in Italy, based on small numbers of cases, have found that seizures are not worse in patients with epilepsy and COVID-19, said Dr. Perry. A few children, including several patients with Dravet syndrome, “had uncomplicated illness and seizures were no worse,” he said. “That is reassuring.”
“Until now, there is no evidence of a direct effect of COVID-19 on seizures or epilepsy,” according to the International League Against Epilepsy (ILAE). “However, patients may experience worsening of seizures due to systemic illnesses, drug interactions, decreased access to antiseizure medications, and increased stress.”
“In younger children, the fever that accompanies COVID-19 may exacerbate seizures, as might any febrile illness,” according to an American Epilepsy Society (AES) resource for epilepsy clinicians. “The main known elevated risk factors related to COVID-19 are age, respiratory disease, and other chronic medical conditions not related to epilepsy. As for all, people with epilepsy should adhere to the CDC recommendations for reducing risk of infection.” Neurologists should review with patients the importance of treatment adherence, update plans for managing breakthrough seizures, and ensure necessary medications are on hand, according to the AES.
The Epilepsy Foundation created a page with information about COVID-19 for patients with epilepsy and recorded a discussion with epilepsy specialists. DEE-P (Developmental Epileptic Encephalopathy–Project) Connections recorded a webinar about protecting medically complex or immune-suppressed children with epilepsy from COVID-19.
MS DMTs and the coronavirus
The National Multiple Sclerosis (MS) Society has provided guidance on the use of disease-modifying therapies (DMTs) during the COVID-19 pandemic. “There are numerous recommendations circulating that attempt to provide clarity and guidance, however, differences among the recommendations have created confusion,” the society says. “DMT decision making varies significantly from country to country, ranging from highly provider-directed to a collaborative decision-making model. ... DMT decisions should be individualized and made collaboratively between the person with MS and his/her healthcare provider.”
Patients with MS and their physicians should weigh risks and benefits before starting cell-depleting DMTs such as alemtuzumab, cladribine, ocrelizumab, or rituximab, according the National MS Society. They also should consider the risks and benefits of DMTs that carry warnings of a potentially severe increase in disability after stopping therapy, such as fingolimod and natalizumab. “We endorse the global advice provided by the MS International Federation (MSIF) – but emphasize that DMT decision making must be individualized and based upon multiple factors,” the National MS Society said.
Neurologists currently lack evidence about how COVID-19 affects patients with MS, according to the MSIF, which based its DMT guidance on advice from MS neurologists and research experts from member organizations. Many DMTs suppress or modify the immune system, and “some MS medications might increase the likelihood of developing complications from a COVID-19 infection but this risk needs to be balanced with the risks of stopping treatment,” according to the federation.
Patients currently taking DMTs should continue treatment, and those who develop symptoms of COVID-19 or test positive for the infection should discuss their DMT with a health care professional familiar with their care, the MSIF recommends. Decisions about starting a DMT should take into account a patient’s disease course, disease activity, and regional COVID-19 risks, according to the federation. For patients due to start DMT, treatments that do not reduce lymphocytes, such as interferons, glatiramer acetate, or natalizumab, should be considered.
Fingolimod, dimethyl fumarate, teriflunomide, and siponimod “may reduce the ability of the immune system to respond to an infection,” and “people should carefully consider the risks and benefits of initiating these treatments during the COVID-19 pandemic,” according to the federation. “People with MS who are currently taking alemtuzumab, cladribine, ocrelizumab, rituximab, fingolimod, dimethyl fumarate, teriflunomide or siponimod and are living in a community with a COVID-19 outbreak should isolate as much as possible to reduce their risk of infection.”
Extended isolation during the COVID-19 outbreak may be warranted for patients with MS who have recently undergone autologous hematopoietic stem cell treatment, which entails intensive chemotherapy, the guidance says. In addition, postponement of this procedure should be considered.
Child neurology, migraine, movement disorders, and stroke
The Child Neurology Foundation (CNF) and Child Neurology Society (CNS) published a joint statement about COVID-19. “Most children who contract COVID-19 appear to exhibit only mild symptoms,” said Scott Pomeroy, MD, president of CNF’s board of directors and chair of the department of neurology at Boston Children’s Hospital, in the statement. “However, if your child is taking a medication such as steroids that can lower their immune system response, there could be an increased risk for more significant symptoms. In addition, children with lung disease, such as asthma, may also be at higher risk. Therefore, it is important to practice preventative precautions. We hope that this information will help to reduce some of the fears that families in our community may be experiencing.”
The American Migraine Foundation shared COVID-19 considerations for patients with migraine from Mia Minen, MD, associate professor of neurology and population health at NYU Langone in New York. Patients with migraine who are otherwise in good health are not expected to be at increased risk of severe COVID-19, according to Dr. Minen. Best practices include having an adequate supply of medicine, considering alternatives to in-person doctor visits, and being “mindful of routine and diet to reduce migraine triggers,” the foundation suggests. In addition, patients should try to limit stress and seek out “alternative methods of social interaction.”
“The relationship between COVID-19 and Parkinson’s disease or other movement disorders remains unknown,” the International Parkinson and Movement Disorder Society said. “In general, we recommend that our movement disorder patients do not assume they are at extreme risks, which for the time being are uncertain. Nevertheless, we strongly recommend following the standard measures strictly to avoid exposures to the virus.”
The American Heart Association (AHA) cautions that older patients with coronary heart disease or hypertension “may be more likely than others to be infected by the coronavirus that causes COVID-19 and to develop more severe symptoms.” In addition, people with a history of stroke “may face a higher risk of complications,” according to the AHA. “As a result, people who have heart disease or another underlying condition should stay home to limit their risk of contracting the virus.”
Several groups emphasized the importance of telemedicine as an option for patients with neurologic conditions during the pandemic. The American Headache Society has hosted discussions on conducting neurologic exams via telemedicine. The American Academy of Neurology also conducted a webinar on telemedicine and COVID-19 and created a page with COVID-19 resources. The journal Neurology is publishing invited commentaries about neurologic aspects of the COVID-19 pandemic.
Neurologic disorders are among the “underlying medical conditions that may increase the risk of serious COVID-19 for individuals of any age,” according to the Centers for Disease Control and Prevention.

DEE-P (Developmental Epileptic Encephalopathy–Project) Connections recorded a webinar about protecting medically complex or immune-suppressed children with epilepsy from COVID-19.
MS DMTs and the coronavirus
The National Multiple Sclerosis (MS) Society has provided guidance on the use of disease-modifying therapies (DMTs) during the COVID-19 pandemic. “There are numerous recommendations circulating that attempt to provide clarity and guidance, however, differences among the recommendations have created confusion,” the society says. “DMT decision making varies significantly from country to country, ranging from highly provider-directed to a collaborative decision-making model. ... DMT decisions should be individualized and made collaboratively between the person with MS and his/her healthcare provider.”
Patients with MS and their physicians should weigh risks and benefits before starting cell-depleting DMTs such as alemtuzumab, cladribine, ocrelizumab, or rituximab, according the National MS Society. They also should consider the risks and benefits of DMTs that carry warnings of a potentially severe increase in disability after stopping therapy, such as fingolimod and natalizumab. “We endorse the global advice provided by the MS International Federation (MSIF) – but emphasize that DMT decision making must be individualized and based upon multiple factors,” the National MS Society said.
Neurologists currently lack evidence about how COVID-19 affects patients with MS, according to the MSIF, which based its DMT guidance on advice from MS neurologists and research experts from member organizations. Many DMTs suppress or modify the immune system, and “some MS medications might increase the likelihood of developing complications from a COVID-19 infection but this risk needs to be balanced with the risks of stopping treatment,” according to the federation.
Patients currently taking DMTs should continue treatment, and those who develop symptoms of COVID-19 or test positive for the infection should discuss their DMT with a health care professional familiar with their care, the MSIF recommends. Decisions about starting a DMT should take into account a patient’s disease course, disease activity, and regional COVID-19 risks, according to the federation. For patients due to start DMT, treatments that do not reduce lymphocytes, such as interferons, glatiramer acetate, or natalizumab, should be considered.
Fingolimod, dimethyl fumarate, teriflunomide, and siponimod “may reduce the ability of the immune system to respond to an infection,” and “people should carefully consider the risks and benefits of initiating these treatments during the COVID-19 pandemic,” according to the federation. “People with MS who are currently taking alemtuzumab, cladribine, ocrelizumab, rituximab, fingolimod, dimethyl fumarate, teriflunomide or siponimod and are living in a community with a COVID-19 outbreak should isolate as much as possible to reduce their risk of infection.”
Extended isolation during the COVID-19 outbreak may be warranted for patients with MS who have recently undergone autologous hematopoietic stem cell treatment, which entails intensive chemotherapy, the guidance says. In addition, postponement of this procedure should be considered.
Child neurology, migraine, movement disorders, and stroke
The Child Neurology Foundation (CNF) and Child Neurology Society (CNS) published a joint statement about COVID-19. “Most children who contract COVID-19 appear to exhibit only mild symptoms,” said Scott Pomeroy, MD, president of CNF’s board of directors and chair of the department of neurology at Boston Children’s Hospital, in the statement. “However, if your child is taking a medication such as steroids that can lower their immune system response, there could be an increased risk for more significant symptoms. In addition, children with lung disease, such as asthma, may also be at higher risk. Therefore, it is important to practice preventative precautions. We hope that this information will help to reduce some of the fears that families in our community may be experiencing.”
The American Migraine Foundation shared COVID-19 considerations for patients with migraine from Mia Minen, MD, associate professor of neurology and population health at NYU Langone in New York. Patients with migraine who are otherwise in good health are not expected to be at increased risk of severe COVID-19, according to Dr. Minen. Best practices include having an adequate supply of medicine, considering alternatives to in-person doctor visits, and being “mindful of routine and diet to reduce migraine triggers,” the foundation suggests. In addition, patients should try to limit stress and seek out “alternative methods of social interaction.”
“The relationship between COVID-19 and Parkinson’s disease or other movement disorders remains unknown,” the International Parkinson and Movement Disorder Society said. “In general, we recommend that our movement disorder patients do not assume they are at extreme risks, which for the time being are uncertain. Nevertheless, we strongly recommend following the standard measures strictly to avoid exposures to the virus.”
The American Heart Association (AHA) cautions that older patients with coronary heart disease or hypertension “may be more likely than others to be infected by the coronavirus that causes COVID-19 and to develop more severe symptoms.” In addition, people with a history of stroke “may face a higher risk of complications,” according to the AHA. “As a result, people who have heart disease or another underlying condition should stay home to limit their risk of contracting the virus.”
Several groups emphasized the importance of telemedicine as an option for patients with neurologic conditions during the pandemic. The American Headache Society has hosted discussions on conducting neurologic exams via telemedicine. The American Academy of Neurology also conducted a webinar on telemedicine and COVID-19 and created a page with COVID-19 resources. The journal Neurology is publishing invited commentaries about neurologic aspects of the COVID-19 pandemic.
Rapid shift to adalimumab biosimilars in Denmark contrasts with U.S. experience
Adalimumab biosimilars are years away from entering the marketplace in the United States because of patent disputes, but they already have led to substantial discounts in Denmark, researchers wrote in JAMA Internal Medicine.
The Danish health care system switched almost entirely to adalimumab biosimilars after the patent on the original adalimumab product, Humira, expired there in October 2018. The switch to biosimilars led to an 82% decrease in costs for the medication, wrote Thomas Bo Jensen, MD, and colleagues in a research letter.
Denmark did not automatically substitute biosimilars, but the Danish Medicines Council recommended adalimumab biosimilars for all indications following Humira’s patent expiration. The recommendations “included switching patients to a biosimilar who were already well treated with the originator,” the researchers wrote.
To study the shift to adalimumab biosimilars across all indications in Denmark and calculate cost reductions, Dr. Jensen, of the department of clinical pharmacology at Copenhagen University Hospital Bispebjerg, and coinvestigators examined monthly data on drug sales from Amgros, which purchases all hospital drugs in the country.
“The proportion of adalimumab biosimilars increased from 71.6% (7,040 of 9,829 pens) in November 2018 to 95.1% (8,974 of 9,438 pens) in December 2018,” the researchers wrote. “Costs of adalimumab decreased by 82.8% from September 2018 to December 2018 (September: 8,197 pens at $5.13 million; December: 9,438 pens at $1.01 million).” The results were similar in rheumatology, dermatology, and gastroenterology.
The Food and Drug Administration has approved five adalimumab biosimilars in the United States, but “they will not enter the market until 2023 owing to patent disputes with AbbVie, the manufacturer of Humira,” wrote Jennifer D. Claytor, MD, of the department of internal medicine at University of California, San Francisco, and Walid Gellad, MD, of the division of general internal medicine at University of Pittsburgh, in an accompanying editorial.
The annual postrebate price of Humira doubled between 2013 and 2018, from $19,000 to $38,000, and these price increases may influence the price of biosimilars, “which will be priced using Humira’s price as an anchor,” Dr. Claytor and Dr. Gellad wrote.
A rapid shift to adalimumab biosimilars across the United States when they become available is “unlikely,” they wrote. Nonetheless, “some health care systems of comparable size to Denmark (e.g., the Veterans Affairs system) and others that are larger (e.g., Kaiser Permanente) ... have the ability to switch products quickly through use of formularies and a prescriber workforce. For example, Kaiser Permanente has successfully replaced Remicade (infliximab) with biosimilars in 80% of patients.”
Given the many biologics in development and increasing health care spending, “we need to take seriously the substantial savings offered by biosimilars and the feasibility, as evidenced by Denmark, of switching to biosimilars quickly once they are available on the market,” Dr. Claytor and Dr. Gellad concluded.
The research was supported by an unrestricted grant from Helsefonden. One author disclosed receiving grants from Pfizer, AbbVie, Roche, and Bristol-Myers Squibb outside the current study. The editorial authors had no disclosures.

Study identifies risk factors for infection after transbronchial biopsy
Among patients who undergo endobronchial ultrasound-guided transbronchial biopsy using a guide sheath (EBUS-GS-TBB) for diagnosing lung cancer, cavitation and low-density areas inside the target lesion on CT and stenosis of the responsible bronchus are risk factors for infection after the procedure, according to a study published in CHEST.
“Infectious complications after [transbronchial biopsy] constitute a serious clinical problem because they might delay the start of treatment or cause the intended treatment to be modified to a milder one,” said Tomohide Souma, MD, of the department of respiratory medicine at Fujita Health University in Toyoake, Japan, and colleagues. “The precise mechanism of such complications is still unclear, and effective prophylaxis procedures have not been established. ... Thus, it is very important to identify the risk factors for infectious complications after TBB if and when these complications are to be avoided.”
To evaluate potential risk factors for infectious complications after EBUS-GS-TBB in a large sample of patients, Dr. Souma and colleagues retrospectively studied the medical records of 1,045 consecutive patients (median age, 72; 68% male) who underwent EBUS-GS-TBB between January 2013 and December 2017 at Fujita Health University Hospital.
In all, 47 patients developed infections, a cumulative incidence of about 4.5%. Infections included pneumonia (51.1%), intratumoral infection (29.8%), and three cases each of lung abscess, pleurisy, and empyema. Three patients, two with empyema and one with lung abscess, died within 1 month before administration of anticancer treatment. “In total, more than 40% of patients with post–EBUS-GS-TBB infection were unable to receive preplanned anticancer treatment,” the researchers said.
On multivariate analysis, cavitation in the lesion (odds ratio, 3.63), low-density areas in the lesion (OR, 13.26), and bronchoscopic findings of responsible bronchus stenosis (OR, 7.82) were significantly associated with development of infections post biopsy.
An analysis that matched 89 patients who received prophylactic antibiotics with controls who did not receive prophylactic antibiotics did not find that prophylactic antibiotics significantly reduced the likelihood of post–EBUS-GS-TBB infection.
“Notably, three risk factors found in our study indicate that the inflammation-prone status of lesions may be the most important factor for developing post–EBUS-TBB infection,” Dr. Souma and colleagues said. “Although our study does not rebuff the role of antibiotics in postbronchoscopy infection therapy, clinicians should notify patients that post-TBB infection may occur despite the use of prophylactic antibiotics. We recommend that careful and frequent follow-up be applied to patients undergoing diagnostic EBUS-GS-TBB with reference to the risk factors identified in our study.”
A. Christine Argento, MD, FCCP, assistant professor of medicine and thoracic surgery and director of the interventional pulmonary fellowship program at Northwestern University, Chicago, noted that this is an important study on a topic that has not been well described in the past.
“This paper ... identifies three factors that were associated with infectious complications – namely, cavitation, low density areas, and a visibly stenosed bronchus leading to the lesion,” she said. “When planning bronchoscopy to sample lesions that fit one of these three criteria, I will likely be more cautious in the future meaning that in these cases, I would limit biopsies to 6-8 pieces which is typically sufficient and I would minimize any trauma to the bronchus leading to the lesion, as if the bronchus is already stenosed on bronchoscopic inspection it is likely inflamed and will only be exacerbated by repeated manipulation and insertions with the bronchoscope and guide sheath leading to a postobstructive phenomenon that was observed in this cohort.
“As far as pleurisy and empyema, it is not described if [the investigators] used fluoroscopy, but this would be an important aspect,” she added. “Ideally, one would not cause disruption of the pleural surface as contamination from the lung to the pleural space can have serious and prolonged infectious consequences as was reported in this study. Fluoroscopy would help the operator to avoid taking samples that would be too close to the pleural surface and could potentially decrease this complication.
“In the United States, it is not always standard practice to see patients 5-7 days following bronchoscopy to assess for complications. Although some of these patients would have presented for evaluation with symptoms, presumably several of these patients would not have. Also pre- and postbronchoscopy labs are not commonly drawn in the United States and so a rise in white blood cells or C-reactive protein would not be known.
“Finally, [the investigators] point out that prophylactic antibiotics do not seem to be effective, and I would agree based on their results. I would only consider using antibiotics as a directed measure if the patient develops infectious complications and the antibiotic choice and duration of therapy would be tailored to the specific complication encountered,” she said.

“Infectious complications after [transbronchial biopsy] constitute a serious clinical problem because they might delay the start of treatment or cause the intended treatment to be modified to a milder one,” said Tomohide Souma, MD, of the department of respiratory medicine at Fujita Health University in Toyoake, Japan, and colleagues. “The precise mechanism of such complications is still unclear, and effective prophylaxis procedures have not been established. ... Thus, it is very important to identify the risk factors for infectious complications after TBB if and when these complications are to be avoided.”
To evaluate potential risk factors for infectious complications after EBUS-GS-TBB in a large sample of patients, Dr. Souma and colleagues retrospectively studied the medical records of 1,045 consecutive patients (median age, 72; 68% male) who underwent EBUS-GS-TBB between January 2013 and December 2017 at Fujita Health University Hospital.
In all, 47 patients developed infections, a cumulative incidence of about 4.5%. Infections included pneumonia (51.1%), intratumoral infection (29.8%), and three cases each of lung abscess, pleurisy, and empyema. Three patients, two with empyema and one with lung abscess, died within 1 month before administration of anticancer treatment. “In total, more than 40% of patients with post–EBUS-GS-TBB infection were unable to receive preplanned anticancer treatment,” the researchers said.
On multivariate analysis, cavitation in the lesion (odds ratio, 3.63), low-density areas in the lesion (OR, 13.26), and bronchoscopic findings of responsible bronchus stenosis (OR, 7.82) were significantly associated with development of infections post biopsy.
An analysis that matched 89 patients who received prophylactic antibiotics with controls who did not receive prophylactic antibiotics did not find that prophylactic antibiotics significantly reduced the likelihood of post–EBUS-GS-TBB infection.
“Notably, three risk factors found in our study indicate that the inflammation-prone status of lesions may be the most important factor for developing post–EBUS-TBB infection,” Dr. Souma and colleagues said. “Although our study does not rebuff the role of antibiotics in postbronchoscopy infection therapy, clinicians should notify patients that post-TBB infection may occur despite the use of prophylactic antibiotics. We recommend that careful and frequent follow-up be applied to patients undergoing diagnostic EBUS-GS-TBB with reference to the risk factors identified in our study.”
A. Christine Argento, MD, FCCP, assistant professor of medicine and thoracic surgery and director of the interventional pulmonary fellowship program at Northwestern University, Chicago, noted that this is an important study on a topic that has not been well described in the past.
“This paper ... identifies three factors that were associated with infectious complications – namely, cavitation, low density areas, and a visibly stenosed bronchus leading to the lesion,” she said. “When planning bronchoscopy to sample lesions that fit one of these three criteria, I will likely be more cautious in the future meaning that in these cases, I would limit biopsies to 6-8 pieces which is typically sufficient and I would minimize any trauma to the bronchus leading to the lesion, as if the bronchus is already stenosed on bronchoscopic inspection it is likely inflamed and will only be exacerbated by repeated manipulation and insertions with the bronchoscope and guide sheath leading to a postobstructive phenomenon that was observed in this cohort.
“As far as pleurisy and empyema, it is not described if [the investigators] used fluoroscopy, but this would be an important aspect,” she added. “Ideally, one would not cause disruption of the pleural surface as contamination from the lung to the pleural space can have serious and prolonged infectious consequences as was reported in this study. Fluoroscopy would help the operator to avoid taking samples that would be too close to the pleural surface and could potentially decrease this complication.
“In the United States, it is not always standard practice to see patients 5-7 days following bronchoscopy to assess for complications. Although some of these patients would have presented for evaluation with symptoms, presumably several of these patients would not have. Also pre- and postbronchoscopy labs are not commonly drawn in the United States and so a rise in white blood cells or C-reactive protein would not be known.
“Finally, [the investigators] point out that prophylactic antibiotics do not seem to be effective, and I would agree based on their results. I would only consider using antibiotics as a directed measure if the patient develops infectious complications and the antibiotic choice and duration of therapy would be tailored to the specific complication encountered,” she said.
The researchers had no disclosures.

Reports suggest possible in utero transmission of novel coronavirus 2019
Reports of three neonates with elevated IgM antibody concentrations whose mothers had COVID-19 in two articles raise questions about whether the infants may have been infected with the virus in utero.
The data, while provocative, “are not conclusive and do not prove in utero transmission” of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), editorialists cautioned.
“The suggestion of in utero transmission rests on IgM detection in these 3 neonates, and IgM is a challenging way to diagnose many congenital infections,” David W. Kimberlin, MD, and Sergio Stagno, MD, of the division of pediatric infectious diseases at University of Alabama at Birmingham, wrote in their editorial. “IgM antibodies are too large to cross the placenta and so detection in a newborn reasonably could be assumed to reflect fetal production following in utero infection. However, most congenital infections are not diagnosed based on IgM detection because IgM assays can be prone to false-positive and false-negative results, along with cross-reactivity and testing challenges.”
None of the three infants had a positive reverse transcriptase–polymerase chain reaction (RT-PCR) test result, “so there is not virologic evidence for congenital infection in these cases to support the serologic suggestion of in utero transmission,” the editorialists noted.
Examining the possibility of vertical transmission
A prior case series of nine pregnant women found no transmission of the virus from mother to child, but the question of in utero transmission is not settled, said Lan Dong, MD, of the department of obstetrics and gynecology at Renmin Hospital of Wuhan University in China and colleagues. In their research letter, the investigators described a newborn with elevated IgM antibodies to novel coronavirus 2019 born to a mother with COVID-19. The infant was delivered by cesarean section February 22, 2020, at Renmin Hospital in a negative-pressure isolation room.
“The mother wore an N95 mask and did not hold the infant,” the researchers said. “The neonate had no symptoms and was immediately quarantined in the neonatal intensive care unit. At 2 hours of age, the SARS-CoV-2 IgG level was 140.32 AU/mL and the IgM level was 45.83 AU/mL.” Although the infant may have been infected at delivery, IgM antibodies usually take days to appear, Dr. Dong and colleagues wrote. “The infant’s repeatedly negative RT-PCR test results on nasopharyngeal swabs are difficult to explain, although these tests are not always positive with infection. ... Additional examination of maternal and newborn samples should be done to confirm this preliminary observation.”
A review of infants’ serologic characteristics
Hui Zeng, MD, of the department of laboratory medicine at Zhongnan Hospital of Wuhan University in China and colleagues retrospectively reviewed clinical records and laboratory results for six pregnant women with COVID-19, according to a study in JAMA. The women had mild clinical manifestations and were admitted to Zhongnan Hospital between February 16 and March 6. “All had cesarean deliveries in their third trimester in negative pressure isolation rooms,” the investigators said. “All mothers wore masks, and all medical staff wore protective suits and double masks. The infants were isolated from their mothers immediately after delivery.”
Two of the infants had elevated IgG and IgM concentrations. IgM “is not usually transferred from mother to fetus because of its larger macromolecular structure. ... Whether the placentas of women in this study were damaged and abnormal is unknown,” Dr. Zeng and colleagues said. “Alternatively, IgM could have been produced by the infant if the virus crossed the placenta.”
“Although these 2 studies deserve careful evaluation, more definitive evidence is needed” before physicians can “counsel pregnant women that their fetuses are at risk from congenital infection with SARS-CoV-2,” Dr. Kimberlin and Dr. Stagno concluded.
Dr. Dong and associates had no conflicts of interest. Their work was supported by the National Key Research and Development Project and others. Dr. Zeng and colleagues had no relevant financial disclosures. Their study was supported by grants from the National Natural Science Foundation of China and Zhongnan Hospital. Dr. Kimberlin and Dr. Stagno had no conflicts of interest.

Cervical pessary didn’t prevent preterm birth in selected women
GRAPEVINE, TEX. – or a composite measure of adverse neonatal outcomes, according to a randomized, open-label study.
“The Arabin pessary should not be used to prevent preterm birth in women with twin pregnancy,” Jane E. Norman, MD, dean of health sciences at the University of Bristol (England), said at the Pregnancy Meeting.
“Preterm birth is very common in twin pregnancy” and leads to “excess neonatal mortality amongst twins,” Dr. Norman said at the meeting, which is sponsored by the Society for Maternal-Fetal Medicine. “Preventing preterm birth is important for both singletons and twins, but it could have even more benefits in twins.”
Emerging evidence has suggested that the Arabin cervical pessary may be useful for the prevention of preterm birth in women with singleton pregnancy and a short cervix. In twin pregnancy, data are more limited.
The ProTwin study randomized 813 women with twin pregnancy to a cervical pessary or standard care. Although the pessary had no impact on preterm birth overall, among women with cervical length of less than 38 mm, those who received a pessary were less likely to have preterm birth. The sample size was small, however, and the average length of the cervix in ProTwin differed from that in a previous U.K. study, Dr. Norman said.
Inspired by the study, Dr. Norman and coinvestigators conducted STOPPIT-2, a multicenter, open-label, randomized, controlled trial to further study whether a certain cervical length threshold was associated with benefit of a cervical pessary in preventing preterm birth. The trial included women with twin pregnancy who had a cervical length ultrasound between 18 and 20 weeks and 6 days of gestation. Women with a cervical length of 35 mm or less were eligible for randomization. Patients received an Arabin pessary plus standard care or standard care alone.
The primary obstetric outcome was spontaneous onset of labor leading to delivery before 34 weeks and 6 days of gestation. The primary neonatal outcome was a composite of outcomes – stillbirth, neonatal death, periventricular leukomalacia, respiratory morbidity, intraventricular hemorrhage, necrotizing enterocolitis, or sepsis – measured up to 28 days after the expected date of delivery.
The investigators randomized 503 women in all, including 250 to the pessary and 253 to standard care. Both groups had similar baseline characteristics, Dr. Norman said. The average age was about 33 years, and the average cervical length was about 29 mm. A total of 20% had monochorionic diamniotic pregnancies, and 80% had dichorionic pregnancies. The researchers excluded women with monochorionic monoamniotic pregnancies. In the pessary group, 16 patients declined the intervention, and 4 were unable to have the pessary inserted.
Spontaneous preterm birth occurred in 18% of patients in the Arabin pessary group, compared with 21% in the standard treatment group. The adjusted odds ratio, 0.87, was not statistically significant. In subgroups of patients with monochorionic pregnancy, cervical length less than 28 mm, or cervical length less than 25 mm, there was no significant benefit.
The composite measure of adverse neonatal outcomes also did not significantly differ between the groups. None of the individual components indicated benefit of the pessary either, Dr. Norman said.
In subgroup analyses, odds ratios for adverse neonatal outcomes were “tending towards harm for the Arabin pessary group ... although clearly none of them conferring statistical significance,” she said. Among women with cervical length less than 28 mm, a primary neonatal outcome – at least one of the adverse outcomes – occurred in 23% of patients in the Arabin pessary group, compared with 20% of patients in the standard care group.
Approximately two-thirds of patients found pessary insertion painless or slightly uncomfortable, whereas about 10% described the experience of device fitting as very uncomfortable, and about 1% described it as the worse pain imaginable.
“Since we started STOPPIT-2, in addition to ProTwin, another three studies have been published on the efficacy of the Arabin pessary in twins,” said Dr. Norman. Combined data show no significant effect of the pessary on preventing preterm birth in twin pregnancy. Still, the meta-analysis does not rule out the possibility that there could subgroups of patients who may benefit from the intervention, Dr. Norman said.
STOPPIT-2 was funded by the National Institute for Health Research (NIHR) in the United Kingdom. Dr. Norman chaired the UK National Institute for Health and Care Excellence guidelines on preterm labor and birth in 2015. In addition, Dr. Norman was a member of a GlaxoSmithKline data safety and monitoring group for a trial of a preterm birth prevention agent, has consulted for Dilafor, and has received research grants for preterm birth prevention from the U.K. Medical Research Council, NIHR, and Tommy’s: Together, for every baby charity.

The investigators randomized 503 women in all, including 250 to the pessary and 253 to standard care. Both groups had similar baseline characteristics, Dr. Norman said. The average age was about 33 years, and the average cervical length was about 29 mm. A total of 20% had monochorionic diamniotic pregnancies, and 80% had dichorionic pregnancies. The researchers excluded women with monochorionic monoamniotic pregnancies. In the pessary group, 16 patients declined the intervention, and 4 were unable to have the pessary inserted.
Spontaneous preterm birth occurred in 18% of patients in the Arabin pessary group, compared with 21% in the standard treatment group. The adjusted odds ratio, 0.87, was not statistically significant. In subgroups of patients with monochorionic pregnancy, cervical length less than 28 mm, or cervical length less than 25 mm, there was no significant benefit.
The composite measure of adverse neonatal outcomes also did not significantly differ between the groups. None of the individual components indicated benefit of the pessary either, Dr. Norman said.
In subgroup analyses, odds ratios for adverse neonatal outcomes were “tending towards harm for the Arabin pessary group ... although clearly none of them conferring statistical significance,” she said. Among women with cervical length less than 28 mm, a primary neonatal outcome – at least one of the adverse outcomes – occurred in 23% of patients in the Arabin pessary group, compared with 20% of patients in the standard care group.
Approximately two-thirds of patients found pessary insertion painless or slightly uncomfortable, whereas about 10% described the experience of device fitting as very uncomfortable, and about 1% described it as the worse pain imaginable.
“Since we started STOPPIT-2, in addition to ProTwin, another three studies have been published on the efficacy of the Arabin pessary in twins,” said Dr. Norman. Combined data show no significant effect of the pessary on preventing preterm birth in twin pregnancy. Still, the meta-analysis does not rule out the possibility that there could subgroups of patients who may benefit from the intervention, Dr. Norman said.
STOPPIT-2 was funded by the National Institute for Health Research (NIHR) in the United Kingdom. Dr. Norman chaired the UK National Institute for Health and Care Excellence guidelines on preterm labor and birth in 2015. In addition, Dr. Norman was a member of a GlaxoSmithKline data safety and monitoring group for a trial of a preterm birth prevention agent, has consulted for Dilafor, and has received research grants for preterm birth prevention from the U.K. Medical Research Council, NIHR, and Tommy’s: Together, for every baby charity.

REPORTING FROM THE PREGNANCY MEETING
Maternal methadone opioid maintenance therapy may be tied to smaller postnatal head circumference
GRAPEVINE, TEX. – compared with opioid maintenance therapy with buprenorphine, according to a study presented at the Pregnancy Meeting.
Antenatal ultrasound measurements do not differ by treatment, however, the researchers said. A separate study suggests that serial ultrasound examinations of fetal brain and biometry measurements may not be helpful in patients who receive these medications for opioid use disorder.
To examine the effects of methadone and buprenorphine opioid maintenance therapy on prenatal and postnatal growth parameters, Jay Davis, MD, a maternal-fetal medicine fellow at Stony Brook University in New York, and coinvestigators conducted a retrospective cohort study using medical records from an academic center during 2007-2017. They included women with singleton pregnancies receiving opioid maintenance therapy with methadone or buprenorphine. They compared head circumference percentile, abdominal circumference percentile, head circumference/abdominal circumference ratio, and postnatal head circumference percentile between the two groups. The investigators analyzed the data using the Wilcoxon–Mann–Whitney test, chi-square test, and logistic regression.
The researchers studied 282 cases, including 120 patients who received buprenorphine and 162 who received methadone. Patients who received buprenorphine delivered at a later average gestational age (39 weeks vs. 37.8 weeks) and had newborns with greater average birth weights (3,206 g vs. 2,877 g). Compared with patients who received methadone, patients who received buprenorphine were significantly more likely to have a larger postnatal head circumference percentile (39 vs. 30), Dr. Davis and colleagues reported. This difference remained significant after controlling for race, prescriber, gestational age at delivery, and birth weight.
In a separate study presented at the meeting sponsored by the Society for Maternal-Fetal Medicine, Jose M. Perez Yordan, MD, of the University of New Mexico, Albuquerque, and colleagues examined effects of medications for opioid use disorder on fetal brain and body measurements.
They found that maternal medications for opioid use disorder do not have a clinically significant effect on fetal brain and body measurements, compared with controls. “No consistent pattern of decreased fetal growth was identified, since the body measurement affected did not persist with serial ultrasounds,” they said. “Serial ultrasound examinations do not appear to be helpful in patients” who take medications of opioid use disorder, with or without alcohol coexposure, unless other risk factors are present.
To evaluate the effects of medications of opioid use disorder and alcohol coexposure on fetal brain and biometric measurements at the second- and third-trimester ultrasound measurements, the investigators are conducting a prospective study known as ENRICH-1. The study includes healthy controls, patients taking medications of opioid use disorder (that is, buprenorphine or methadone), and patients taking medications of opioid use disorder with alcohol coexposure.
Ultrasound measurements from the second and third trimesters evaluated biparietal diameter, femur length, frontal lobe width and length, front-thalamic distance, and caval-calvarial distance. Univariate and multivariate analyses assessed differences in measurements adjusting for gestational age and other factors.
The present analysis included data from 171 participants, including 56 healthy controls, 75 patients taking medications of opioid use disorder, and 40 patients taking medications of opioid use disorder with alcohol coexposure. There was no consistent pattern of decreased fetal growth. Affected measurements did not persist over time.
The study presented by Dr. Perez Yordan was supported by a National Institute on Alcohol Abuse and Alcoholism grant. The remaining investigators in both studies had no relevant financial disclosures.
