Background:
The prevalence of COVID-19 is different in studies conducted in different countries. The aim of this systematic review and meta-analysis is to estimate the pooled prevalence of COVID-19 in patients with MS.
Methods:
Two independent researchers independently searched PubMed, Scopus, EMBASE, Web of Science, and google scholar along with gray literature up to April 2021. The search strategy included the MeSH and text words as (((coronavirus OR Wuhan coronavirus OR novel coronavirus OR coronavirus disease OR COVID-19 OR 2019 novel coronavirus infection OR 2019-nCOV OR severe acute respiratory syndrome coronavirus 2 OR SARS-CoV-2) AND (Multiple Sclerosis OR Sclerosis, Multiple) OR Sclerosis, Disseminated) OR Disseminated Sclerosis) OR MS (Multiple Sclerosis)) OR Multiple Sclerosis, Acute Fulminating).
Results:
We found 1466 articles by literature search, and after deleting duplicates, 1029 remained. Twelve articles remained for meta-analysis. Totally, 101,462 patients were evaluated and the total number of possible/confirmed cases was 1394. Mean age ranged from 35 to 54 years. Totally, 49 patients died. The pooled prevalence of suspected COVID-19 in MS patients was 4% (95% CI: 3-4%) (I2 = 98.5%, P < 0.001). The pooled prevalence of hospitalization in infected cases was 10% (95% CI: 7-12%) (I2 = 95.6%, P < 0.001). The pooled prevalence of death in hospitalized cases was 4% (95% CI: 1-6%) (I2 = 82.4%, P < 0.001).
Conclusion:
Hospitalization rate is higher among MS patients based on COVID-19 infection while the pooled infection rate is estimated as 4%.
Insights
The pooled prevalence of COVID-19 infection in multiple sclerosis (MS) patients is 4%. Hospitalization rates were higher in MS patients with COVID-19, with 10% hospitalized and 4% of those dying.
Area of Science:
- Epidemiology
- Infectious Diseases
- Neurology
Background:
- COVID-19 prevalence varies globally, necessitating specific population studies.
- Multiple Sclerosis (MS) is a chronic neurological disease affecting immune responses.
- Understanding COVID-19 impact on MS patients is crucial for clinical management.
Purpose of the Study:
- To estimate the pooled prevalence of COVID-19 infection in patients with Multiple Sclerosis (MS).
- To analyze hospitalization and mortality rates associated with COVID-19 in MS patients.
Main Methods:
- Systematic review and meta-analysis of studies up to April 2021.
- Searched multiple databases including PubMed, Scopus, EMBASE, Web of Science, and Google Scholar.
- Included MeSH and text words for COVID-19 and Multiple Sclerosis (MS) variants.
Main Results:
- Analyzed 12 articles from an initial 1466, evaluating 101,462 patients.
- The pooled prevalence of suspected COVID-19 in MS patients was 4% (95% CI: 3-4%).
- Hospitalization rate was 10% (95% CI: 7-12%), and mortality among hospitalized MS patients was 4% (95% CI: 1-6%).
Conclusions:
- The overall pooled prevalence of COVID-19 infection among MS patients is estimated at 4%.
- MS patients with COVID-19 exhibited a higher hospitalization rate compared to the general population.
- Findings highlight the importance of monitoring and managing COVID-19 in MS patient cohorts.
