Dhamija K, Bhatia R, Srivastava MVP, Singh G, Bali P, Rani A. Outcomes of COVID-19 disease and its effect on disability in patients with multiple sclerosis and other allied demyelinating disorders. Clin Neurol Neurosurg 2024; 237:108160. [PMID: 38350173 DOI: 10.1016/j.clineuro.2024.108160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 01/31/2024] [Accepted: 02/01/2024] [Indexed: 02/15/2024]
Abstract
BACKGROUND Coronavirus disease of 2019 (COVID-19) pandemic has posed challenges for clinicians with respect to questions regarding vulnerability of patients with chronic autoimmune diseases like Multiple Sclerosis (MS) and other demyelinating central nervous system (CNS) disorders. OBJECTIVES We assessed outcomes of COVID-19 disease among patients with CNS demyelinating disorders and its effect on neurological disability. METHODS This was an electronic survey in which a structured questionnaire was distributed to patients registered with neuroimmunology and MS clinics at All India Institute of Medical Sciences, New Delhi, India. The patients were enquired for their primary disease characteristics, occurrence and course of COVID-19 infection and its effect on their underlying disability, if any. Patients visiting clinics in person were also assessed and data from both sources was pooled. RESULTS 61 patients with these disorders reported to have contracted COVID-19 infection (mean age- 35.60+10.28 years, females-75.4%, MS-85.2%). None of them suffered from severe/critical COVID-19 despite heterogeneity of disease modifying therapy (DMT) use. DMTs were not associated with increased risk of lymphopenia during illness. 3.3% patients reported fresh relapse and 16.4% had worsening of their neurological disability during/after COVID-19 infection with half of them not attaining their baseline status on follow-up. None of demographic or biochemical parameters were predictive of this neurological worsening. CONCLUSION Our study suggests that patients with these disorders might not be at heightened risk of severe COVID-19. Adverse effect of COVID-19 infection on neurological disability needs further exploration.

Andersen ML, Zegers FD, Jølving LR, Knudsen T, Stenager E, Nørgård BM. Patients with multiple sclerosis: COVID-19 related disease activity and hospitalisations based on a nationwide cohort study. Mult Scler Relat Disord 2023; 79:105031. [PMID: 37778157 DOI: 10.1016/j.msard.2023.105031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 09/15/2023] [Accepted: 09/24/2023] [Indexed: 10/03/2023]
Abstract
BACKGROUND It has not previously been clarified if COVID-19 triggers disease activity and increases the risk of hospitalisation with COVID-19 in patients with multiple sclerosis. We examined the association between COVID-19 and the use of systemic corticosteroids prescriptions and hospital contacts at neurological departments as proxies of disease activity among patients with multiple sclerosis. Furthermore, we examined whether patients with multiple sclerosis were more likely to be hospitalised with COVID-19 compared to references. METHODS This study was based on nationwide health registries with data on the Danish population of 2,222,946 individuals with a positive COVID-19 PCR test. To study disease activity our study population consisted of all patients with multiple sclerosis and a positive COVID-19 PCR test. Our proxies for disease activity were compared after versus before a positive COVID-19 PCR test using a binomial regression model. Adjustments were made for age, sex, comorbidity, length of multiple sclerosis diagnosis, calendar period, vaccination, and immunomodulatory treatment. To study the risk of hospitalisation with COVID-19 in patients with multiple sclerosis our study population here consisted of all Danish citizens with a COVID-19 positive PCR test. In logistic regression models we estimated odds ratio (OR) for hospitalisation with COVID-19 in patients with multiple sclerosis relative to patients affected with other autoimmune diseases (inflammatory bowel disease/rheumatoid arthritis), and relative to individuals from the general population. Adjustments were made for age, sex, comorbidity, vaccination, and calendar period. To examine the impact of disease-modifying treatment, the risk of hospitalisation with COVID-19 was estimated in those with disease-modifying treatment versus those without any disease-modifying treatment. RESULTS We included 7358 patients with multiple sclerosis and a positive COVID-19 PCR test. The adjusted incidence rate ratio (aIRR) for having corticosteroid prescriptions after COVID-19 in patients with multiple sclerosis was 0.93 (95 % CI 0.78 - 1.10), and the aIRR for hospital contacts at neurological departments/admissions with multiple sclerosis as primary diagnosis after COVID-19 infection was 1.10 (95 % 1.00-1.22). Adjusted OR (aOR) for hospitalisation with COVID-19 in the 30 days after a positive COVID-19 PCR test was 3.21 (95 % CI 2.75-3.74) compared to patients with other autoimmune diseases and the aOR was 5.34 (95 % CI 4.65-6.14) for patients with multiple sclerosis compared to all other individuals in the general population with a positive test. We found no increased risk of hospitalisations with COVID-19 in patients with multiple sclerosis using disease-modifying treatment 6 months prior to a positive COVID-19 PCR test compared to patients with multiple sclerosis without disease-modifying treatment (aOR 0.94 (95 % CI 0.69-1.27)). CONCLUSIONS In this nationwide cohort of patients with multiple sclerosis, COVID-19 did not seem to trigger multiple sclerosis disease activity (based on proxy variables). We found a significantly increased risk of being hospitalised with COVID-19 in the first 30 days after a positive COVID-19 PCR test in patients with multiple sclerosis irrespective of the type of reference population. In patients with multiple sclerosis, the use of disease-modifying treatment did not increase the risk of hospitalisation with COVID-19.

The disease course of multiple sclerosis before and during COVID-19 pandemic: A retrospective five-year study. Mult Scler Relat Disord 2022; 65:103985. [PMID: 35759904 PMCID: PMC9212895 DOI: 10.1016/j.msard.2022.103985] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 06/13/2022] [Accepted: 06/17/2022] [Indexed: 01/13/2023]
Abstract
Introduction COVID-19 pandemic is thought to influence the natural history of immune disorders, yet the knowledge on its effect on multiple sclerosis (MS) is unknown and not fully understood for which we conducted this retrospective study. Methods and materials We included all patients with MS seen in King Faisal Specialist Hospital and Research Centre in Jeddah, Saudi Arabia, between January 2017 and October 20201. We determined clinical and radiological evidence of disease activities in all patients by the end of the study period, and we compared the disease patterns before and during the pandemic. We also identified patients with COVID-19 since March 2020, who had at least 3 months of follow-up following the infection. Results We studied 301 patients; 216 (72%) were women, the mean age was 38 years (range; 16, 73 years), the mean disease duration was 10 years (range; 1, 36 years), and the median EDSS score was 0.5 (range; 0, 8). RRMS accounted for most of the cases (270 patients). MS disease activities were 25% less prevalent during the pandemic compared to the preceding 3 years (26 vs. 51%, respectively, p < 0.01). Bivariate analysis showed significant higher disease activities in patients younger than 35 years (73 vs 27%), on DMT (68 vs 32%), and complaint to therapy (69 vs 31%). Multiple logistic regression analysis showed that the likelihood of MS disease activities were 3 times more during the pre-pandemic era (adjusted OR = 3.1, p value < 0.05, 95% CI; 1.4, 7.1). Thirty patients (10%) were infected with COVID-19. All patients reported mild symptoms, and none required hospitalization. COVID-19 was prevalent among younger patients with RRMS, with low EDSS scores, irrespective of DMTs they received. COVID-19 infection was not associated with clinical relapses or MRI changes. Disease activities were dependent on DMT use and not COVID-19 status. Multivariate analyses also confirmed no effect of COVID-19 on disease activities (p = 0.3 and 0.4, for clinical and MRI changes, respectively). Conclusions MS disease activities did not increase during the pandemic, yet the apparent decrease in the disease activities is probably due to under reporting and not a real decrease in disease activities because of the pandemic. The COVID-19 infection in our MS patients showed a benign disease course, yet standard precautions to reduce the risk of COVID-19 transmission should be applied accordingly.

SARS-CoV-2 mRNA Vaccination in People with Multiple Sclerosis Treated with Fingolimod: Protective Humoral Immune Responses May Develop after the Preferred Third Shot. Vaccines (Basel) 2022; 10:341. [PMID: 35214799 PMCID: PMC8875864 DOI: 10.3390/vaccines10020341] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 02/15/2022] [Accepted: 02/19/2022] [Indexed: 02/01/2023] Open
Abstract
Evidence suggests limited development of protective IgG responses to mRNA-based vaccines in sphingosine-1-phosphate receptor (S1PR)-modulator treated individuals with multiple sclerosis (MS). We studied the extent of the humoral immune response after the preferred third mRNA SARS-CoV-2 vaccine in S1PR-modulator treated people with MS (pwMS) and insufficient IgG responses after the standard immunization scheme. Eight pwMS that were treated with fingolimod received a third homologous SARS-CoV-2 mRNA vaccine dose, either the Moderna's mRNA-1273 or Pfizer-BioNTech's BNT162b2 vaccine. We quantified the serum levels of IgG antibodies against the receptor-binding domain of SARS-CoV-2 four weeks later. An antibody titer of 100 AU/mL or more was considered protective. After the third vaccination, we found clinically relevant IgG titers in four out of eight individuals (50%). We conclude that the humoral immune response may reach protective levels after the third preferred dose of the homologous SARS-CoV-2 mRNA vaccine. Vaccine shots in S1PR-modulator treated pwMS ahead of schedule may be a strategy to overcome insufficient humoral immune responses following the standard vaccination scheme.

Abstract
Recent interest in multiple sclerosis research warrants literature analysis to evaluate the current state of the discipline and new research domains. This bibliometric review summarised the research trends and analysed research areas in multiple sclerosis over the last decade. The documents containing the term 'multiple sclerosis' in the article title were retrieved from the Scopus database. We used Harzing's Publish or Perish and VOSviewer for citation analysis and data visualisation, respectively. We found a total of 18,003 articles published in journals in the English language between 2012 and 2021. The emerging keywords identified utilising the enhanced strategic diagram were 'covid-19', 'teriflunomide', 'clinical trial', 'microglia', 'b cells', 'myelin', 'brain', 'white matter', 'functional connectivity', 'pain', 'employment', 'health-related quality of life', 'meta-analysis' and 'comorbidity'. This study demonstrates the tremendous growth of multiple sclerosis literature worldwide, which is expected to grow more than double during the next decade especially in the identified emerging topics.

Abstract
Coronavirus disease (COVID-19) appeared in December 2019 in the Chinese city of Wuhan and has quickly become a global pandemic. The disease is caused by the severe acute respiratory syndrome coronavirus type-2 (SARS-CoV-2), an RNA beta coronavirus phylogenetically similar to SARS coronavirus. To date, more than 132 million cases of COVID19 have been recorded in the world, of which over 2.8 million were fatal ( https://coronavirus.jhu.edu/map.html ). A huge vaccination campaign has started around the world since the end of 2020. The availability of vaccines has raised some concerns among neurologists regarding the safety and efficacy of vaccination in patients with multiple sclerosis (MS) taking immunomodulatory or immunosuppressive therapies.

Abstract
Background and Objectives Inhibition of de novo pyrimidine synthesis in proliferating T and B lymphocytes by teriflunomide, a pharmacological inhibitor of dihydroorotate dehydrogenase (DHODH), has been shown to be an effective therapy to treat patients with MS in placebo-controlled phase 3 trials. Nevertheless, the underlying mechanism contributing to the efficacy of DHODH inhibition has been only partially elucidated. Here, we aimed to determine the impact of teriflunomide on the immune compartment in a longitudinal high-dimensional follow-up of patients with relapse-remitting MS (RRMS) treated with teriflunomide. Methods High-dimensional spectral flow cytometry was used to analyze the phenotype and the function of innate and adaptive immune system of patients with RRMS before and 12 months after teriflunomide treatment. In addition, we assessed the impact of teriflunomide on the migration of memory CD8 T cells in patients with RRMS, and we defined patient immune metabolic profiles. Results We found that 12 months of treatment with teriflunomide in patients with RRMS does not affect the B cell or CD4 T cell compartments, including regulatory TREG follicular helper TFH cell and helper TH cell subsets. In contrast, we observed a specific impact of teriflunomide on the CD8 T cell compartment, which was characterized by decreased homeostatic proliferation and reduced production of TNFα and IFNγ. Furthermore, we showed that DHODH inhibition also had a negative impact on the migratory velocity of memory CD8 T cells in patients with RRMS. Finally, we showed that the susceptibility of memory CD8 T cells to DHODH inhibition was not related to impaired metabolism. Discussion Overall, these findings demonstrate that the clinical efficacy of teriflunomide results partially in the specific susceptibility of memory CD8 T cells to DHODH inhibition in patients with RRMS and strengthens active roles for these T cells in the pathophysiological process of MS.

Abstract
Teriflunomide, a once daily, oral disease-modifying therapy, has demonstrated consistent efficacy, safety and tolerability in patients with relapsing forms of multiple sclerosis (MS) and with a first clinical episode suggestive of MS treated up to 12 years. This review is an update to a previous version that examined data from the teriflunomide core clinical development program and extension studies. Data have since become available from active comparator trials with other disease-modifying therapies, treatment-related changes in brain volume (analyzed using structural image evaluation using normalization of atrophy) and real-world evidence including patient-reported outcomes. Initial data on the potential antiviral effects of teriflunomide in patients with MS, including case reports of patients infected with the 2019 novel coronavirus (SARS-CoV-2), are also presented.

Vaccines (Basel) 2021; 9:773. [PMID: 34358189 PMCID: PMC8310076 DOI: 10.3390/vaccines9070773] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 07/06/2021] [Accepted: 07/07/2021] [Indexed: 12/11/2022] Open
Abstract
Understanding the risks of COVID-19 in patients with Multiple Sclerosis (MS) receiving disease-modifying therapies (DMTs) and their immune reactions is vital to analyze vaccine response dynamics. A systematic review on COVID-19 course and outcomes in patients receiving different DMTs was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Emerging data on SARS-CoV-2 vaccines was used to elaborate recommendations. Data from 4417 patients suggest that MS per se do not portend a higher risk of severe COVID-19. As for the general population, advanced age, comorbidities, and higher disability significantly impact COVID-19 outcomes. Most DMTs have a negligible influence on COVID-19 incidence and outcome, while for those causing severe lymphopenia and hypogammaglobulinemia, such as anti-CD20 therapies, there might be a tendency of increased hospitalization, worse outcomes and a higher risk of re-infection. Blunted immune responses have been reported for many DMTs, with vaccination implications. Clinical evidence does not support an increased risk of MS relapse or vaccination failure, but vaccination timing needs to be individually tailored. For cladribine and alemtuzumab, it is recommended to wait 3-6 months after the last cycle until vaccination. For the general anti-CD20 therapies, vaccination must be deferred toward the end of the cycle and the next dose administered at least 4-6 weeks after completing vaccination. Serological status after vaccination is highly encouraged. Growing clinical evidence and continuous surveillance are extremely important to continue guiding future treatment strategies and vaccination protocols.

Abstract
Few studies have focused on immune status and disease activity in MS patients during the coronavirus disease 2019 (COVID-19) pandemic. The aim of this study is to investigate immune status, COVID-19 infection, and attacks in MS patients during the pandemic. An online questionnaire about COVID-19 infection, MS attack, and MS treatment during the pandemic was administered to all 525 MS patients registered in our hospital database from January 1, 2011, to June 1, 2020. Only 384 responded, of which 361 patients could be included in the final analysis. During the pandemic, 42.1% of the 361 patients and 65.0% of the 234 patients on immunotherapies were exposed to teriflunomide. Compared to patients who didn't receive treatment, patients exposed to DMTs had significantly lower levels of neutrophils (P < 0.01) and immunoglobulin G (P < 0.01), and patients exposed to immunosuppressants had significantly lower levels of immunoglobulin G (P < 0.05). Over 80% of our patients followed effective protective measures and none of the 361 MS patients in our cohort contracted COVID-19. Patients whose treatment was disrupted had a significantly higher annualized relapse rate (ARR) during than before the pandemic (P < 0.01), while the ARR of patients with continuous treatment or without treatment remained unchanged. During the pandemic, the risk of MS attack due to treatment disruption possibly outweighs the risk of COVID-19 infection under preventive measures, and MS treatment maintenance might be necessary.

Curr Neuropharmacol 2021; 20:107-125.

Abstract
Since COVID-19 has emerged as a word public health problem, attention has been focused on how immune-suppressive drugs used for the treatment of autoimmune disorders influence the risk for SARS-CoV-2 infection and the development of acute respiratory distress syndrome (ARDS). Here, we discuss the disease-modifying agents approved for the treatment of multiple sclerosis (MS) within this context. Interferon (IFN)-β1a and -1b, which display antiviral activity, could be protective in the early stage of COVID-19 infection, although SARS-CoV-2 may have developed resistance to IFNs. However, in the hyperinflammation stage, IFNs may become detrimental by facilitating macrophage invasion in the lung and other organs. Glatiramer acetate and its analogues should not interfere with the development of COVID-19 and may be considered safe. Teriflunomide, a first-line oral drug used in the treatment of relapsing-remitting MS (RRMS), may display antiviral activity by depleting cellular nucleotides necessary for viral replication. The other first-line drug, dimethyl fumarate, may afford protection against SARS-CoV-2 by activating the Nrf-2 pathway and reinforcing the cellular defenses against oxidative stress. Concern has been raised regarding the use of second-line treatments for MS during the COVID-19 pandemic. However, this concern is not always justified. For example, fingolimod might be highly beneficial during the hyperinflammatory stage of COVID-19 for a number of mechanisms, including the reinforcement of the endothelial barrier. Caution is suggested for the use of natalizumab, cladribine, alemtuzumab, and ocrelizumab, although MS disease recurrence after discontinuation of these drugs may overcome a potential risk for COVID-19 infection.

Abstract
In December 2019, coronavirus disease 2019 (COVID-19) emerged in Wuhan and rapidly spread throughout China. Since the outbreak of the pandemic, in addition to the well-known COVID-19 symptoms, various neurological symptoms have been also described in patients with COVID-19. Here, we report an unusual presentation of COVID-19 infection in a teriflunomide-treated individual with multiple sclerosis (MS) who did not interrupt teriflunomide treatment during the infection. The course of the infection was mild in this case as in other reported teriflunomide-treated individuals with COVID-19. COVID-19's presentation may be unusual in people with MS (pwMS). It can also be concluded that teriflunomide may be considered a safe disease-modifying treatment option during the pandemic.

Abstract
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic is a challenge for all participants in the healthcare system. At the beginning of the pandemic, many physicians asked themselves what risk their patients, especially those with chronic diseases, were exposed to. We present an overview of all patients with multiple sclerosis (MS) and SARS-CoV-2 infection published in the literature so far. In total, there are publications on 873 SARS-CoV-2 positive MS patients and information on the outcome can be given for 700 patients. With regard to the different disease modifying therapies (DMTs), by far the most cases were described under anti-CD20 treatment (n = 317). The mortality rate of all MS patients was 4% and a further 3% required invasive or non-invasive ventilation. When looking at the severe and fatal cases, it is particularly noticeable that patients without DMTs, with previous cardiovascular diseases, or with a severe degree of disability are at risk. Immunosuppressive therapy itself does not appear to be a substantial risk factor. Rather, it is reasonable to assume that the therapies could be protective, either directly, by mitigating the cytokine storm, or indirectly, by reducing the disease activity of MS.
