ObjectiveWe systematically reviewed the literature on COVID-19 in patients with multiple sclerosis (MS).MethodsWe searched PubMed, Scopus, EMBASE, CINAHL, Web of Science, Google Scholar, and World Health Organization database from December 1, 2019, to December 18, 2020. Three conference abstract databases were also searched. We included any types of studies that reported characteristics of patients with MS with COVID-19.ResultsFrom an initial 2,679 publications and 3,138 conference abstracts, 87 studies (67 published articles and 20 abstracts) consisting of 4,310 patients with suspected/confirmed COVID-19 with MS met the inclusion criteria. The female/male ratio was 2.53:1, the mean (SD) age was 44.91 (4.31) years, the mean disease duration was 12.46 (2.27), the mean Expanded Disability Status Scale score was 2.54 (0.81), the relapsing/progressive ratio was 4.75:1, and 32.9% of patients had at least 1 comorbidity. The most common symptoms were fever (68.8%), followed by cough (63.9%), fatigue/asthenia (51.2%), and shortness of breath (39.5%). In total, 837 of 4,043 patients with MS with suspected/confirmed COVID-19 (20.7%) required hospitalization, and 130 of 4,310 (3.0%) died of COVID-19. Among suspected/confirmed patients, the highest hospitalization and mortality rates were in patients with no disease-modifying therapies (42.9% and 8.4%), followed by B cell–depleting agents (29.2% and 2.5%).ConclusionOur study suggested that MS did not significantly increase the mortality rate from COVID-19. These data should be interpreted with caution as patients with MS are more likely female and younger compared with the general population where age and male sex seem to be risk factors for worse disease outcome.

In December 2019, a novel coronavirus causing an infectious respiratory disease was identified, which since then has developed into a pandemic with higher rates of mortality in older individuals and those with underlying medical conditions. 1 Multiple sclerosis (MS) is an immune-mediated neurologic disease which requires long-term treatment with immunotherapies that have been shown to increase the risk of infections. 2 As a result, there is significant anxiety among patients and neurologists during the pandemic regarding the infection outcome in this patient population. We present a patient with MS treated with fingolimod who was diagnosed with COVID-19 and had a favorable outcome. Case presentationA 42-year-old woman who was diagnosed with relapsing-remitting MS according to the McDonald criteria in 2001 and had been treated with methotrexate (2 years; discontinued because of elevated liver enzymes), interferon beta 1-a (13 years; discontinued because of disease activity), and recently on fingolimod (since 4 years ago) presented with muscle aches, gait difficulty, sensory disturbances, and weakness on the right side. Her other comorbidities included major depression disorder, hypothyroidism, recurrent urinary tract infection, and histories of pulmonary embolism on direct oral anticoagulation and myasthenia gravis (diagnosed 5 years before MS and status after thymectomy). At her most recent follow-up in September 2019, her expanded disability status scale (EDSS) score was 1.0 for a positive Babinski sign on the right side. MRI was notable for moderate disease burden in the brain and the presence of 2 right-sided cervical cord lesions. Her lymphocyte count at this visit was 842.4/μL.On March 1, 2020, she started experiencing the symptoms that gradually worsened over the next few days. She sought medical attention on March 5 and was seen at the outpatient MS clinic. Neurologic examination revealed decreased sensation, reduced muscle strength (4/5), and brisk reflexes on the right and right positive Babinski sign (EDSS of 4). These findings were consistent with new relapse or recrudescence of old symptoms (pseudoexacerbation). She was then admitted for a relapse workup and treatment on the same day. On arrival, she was afebrile with vital signs within normal limits. Initial laboratory investigations were notable for C-reactive protein of 76 mg/L and erythrocyte sedimentation rate of 46 mm, raising suspicious for an underlying infectious etiology. There was also a decrease in absolute lymphocyte count (601.6/μL), which was attributed to fingolimod. Methylprednisolone IV 1,000 mg/d was initiated for 3 days for the treatment of a possible relapse. As part of the infectious workup, chest X-ray showed a ground glass opacity ( figure, A), which raised a possibility of community-acquired pneumonia for which she was started on azithromycin 500 mg daily because she is allergic to fluoroquinolones. On March 7, she developed dry cough, dyspnea, and fever (38.7°C). She also had tachycardia (122), increased respiratory rate (30...

The effect of coronavirus disease (COVID-19) on the risk of relapse in multiple sclerosis (MS) have been unknown. In this retrospective study of 41 relapsing-remitting MS patients, number of relapses in pre-defined at risk-period (ARP) was compared with the previous two years. During the previous two years, a total of 32 attacks was reported, which 5 (15.6%) were during the at-risk period. After adjusting for age and sex, there was an increased risk of attack during ARP compared to the previous two years (RR: 2.566, 95%CI: 1.075-6.124, P=0.034). Our preliminary study suggested that COVID-19 can trigger exacerbation of MS.

Background: Compared to the adult onset of multiple sclerosis (AOMS), both early-onset (EOMS) and late-onset (LOMS) are much less frequent, but are often under- or misdiagnosed. The aims of the present study were: 1. To compare demographic and clinical features of individuals with EOMS, AOMS and LOMS, and 2. To identify predictors for disability progression from relapsing remitting MS (RRMS) to secondary progressive MS (SPMS). Method: Data were taken from the Isfahan Hakim MS database. Cases were classified as EOMS (MS onset ≤ 18 years), LOMS (MS onset >50 years) and AOMS (MS >18 and ≤ 50 years). Patients’ demographic and clinical (initial symptoms; course of disease; disease patterns from MRI; disease progress) information were gathered and assessed. Kaplan–Meier and Cox proportional hazard regressions were conducted to determine differences between the three groups in the time lapse in conversion from relapsing remitting MS to secondary progressive MS. Results: A total of 2627 MS cases were assessed; of these 127 were EOMS, 84 LOMS and 2416 AOMS. The mean age of those with EOMS was 14.5 years; key symptoms were visual impairments, brain stem dysfunction, sensory disturbances and motor dysfunctions. On average, 24.6 years after disease onset, 14.2% with relapsing remitting MS (RRMS) were diagnosed with secondary progressive MS (SPMS). The key predictor variable was a higher Expanded Disability Status Scale (EDSS) score at disease onset. Compared to individuals with AOMS and LOMS, those with EOMS more often had one or two relapses in the first two years, and more often gadolinium-enhancing brain lesions. For individuals with AOMS, mean age was 29.4 years; key symptoms were sensory disturbances, motor dysfunctions and visual impairments. On average, 20.5 years after disease onset, 15.6% with RRMS progressed to SPMS. The key predictors at disease onset were: a higher EDSS score, younger age, a shorter inter-attack interval and spinal lesions. Compared to individuals with EOMS and LOMS, individuals with AOMS more often had either no or three and more relapses in the first two years. For individuals with LOMS, mean age was 53.8 years; key symptoms were motor dysfunctions, sensory disturbances and visual impairments. On average, 14 years after disease onset, 25.3% with RRMS switched to an SPMS. The key predictors at disease onset were: occurrence of spinal lesions and spinal gadolinium-enhancement. Compared to individuals with EOMS and AOMS, individuals with LOMS more often had no relapses in the first two years, and higher EDSS scores at disease onset and at follow-up. Conclusion: Among a large sample of MS sufferers, cases with early onset and late onset are observable. Individuals with early, adult and late onset MS each display distinct features which should be taken in consideration in their treatment.

Background Psychological well-being assessment during the COVID-19 pandemic is essential for patients with multiple sclerosis (MS). The goal of this study is to evaluate fear of relapse, social support, and psychological well-being (depression, anxiety, and stress level) of Iranian patients with MS during the COVID-19 pandemic stage. Methods One hundred and sixty-five patients were enrolled. We asked all cases to fill valid and reliable Persian version of depression, anxiety, and stress scale (DASS-21), perceived social support, and fear of relapse scale questionnaires. Results One hundred and sixty-five patients were enrolled. Female to male ratio was (F/M) = 4.6. Mean age and mean duration of disease were 35.3±8.6 and 7.1±5 years, respectively. Mean scores of social support, DASS, and FoR questionnaires were 63.1±16.8, 16.4±13.4, and 51.4±17.3, respectively. There was a significant negative correlation between social support and FoR scores and also significant positive correlations between components of DASS and FoR. Linear regression analysis by considering FoR as dependent variable and age, sex, marital status, duration of the disease, and EDSS as dependent variables showed that sex was an independent predictor of FoR score. Conclusion Psychological well-being as well as fear of relapse should be considered in patients with MS during the COVID-19 pandemic stage.
