Fatigue is one of the major symptoms, occurring in 30-90% of people with post-COVID-19 syndrome. This study aims at describing factors associated with fatigue in people with Post-COVID-19 seen in our newly established Post-Covid clinic. Methods This retrospective single center study included 42 consecutive patients suffering from Post-COVID-19 syndrome treated at the Department of Neurology, University Hospital Bern, between 11/2020 and05/2021. Clinical phenomenology of Post-COVID-19 syndrome with a special focus on fatigue and risk factor identification was performed using Mann-Whitney U Test, Pearson Correlation, and Chi-Quadrat-Test. Results Fatigue (90.5%) was the most prevalent Post-COVID-19 symptom followed by depressive mood (52.4%) and sleep disturbance (47.6%). Fatigue was in mean severe (Fatigue severity scale (FSS) mean 5.5 points (95% Confidence interval (95CI) 5.1 - 5.9, range .9 - 6.9, n = 40), and it was unrelated to age, COVID-19 severity or sex. The only related factors with fatigue severity were daytime sleepiness and depressed mood. Conclusion Fatigue is the main symptom of the Post-COVID-19 syndrome in our cohort. Further studies describing this syndrome are needed to prepare the healthcare systems for the challenge of treating patients with Post-COVID-19 syndrome.","PeriodicalId":15218,"journal":{"name":"Journal of Central Nervous System Disease","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47691164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a proportion of patients treated with these agents continue to experience relapses and disease progression. Cladribine tablets, approved in 2017 for highly active relapsing MS, comprise a sparsely administered oral treatment which exerts its therapeutic effect through a reduction and subsequent repletion of the lymphocyte population. Purpose/Study Sample Here we describe the design of CLAD CROSS, a prospective, non-interventional, multicenter, Phase IV study in patients with a confirmed diagnosis of RRMS who switch from first-line disease modifying drugs (DMDs) to treatment with cladribine tablets in routine clinical practice. 242 adult patients will be recruited in 61 sites (6 countries) over 30 months and will be followed up for 2 years following prescription of cladribine tablets per the decision of the treating physicians. Research Design The primary endpoint is the change in annualized relapse rate (ARR) between the 12-month pre-baseline period and over the 12-month period before end of study. Secondary endpoints are the percentage of patients with 6-month disability progression or improvement at the end of the study, measured by the Expanded Disability Status Scale, Timed 25 Foot Walk and 9-Hole Peg Test scales and quality of life, treatment satisfaction, and healthcare resource utilization, measured through the MSIS-29, TSQM 1.4, and EQ-5D-3L scales, respectively. MRI lesions will be compared in the exploratory setting between the 12-month pre-baseline period, baseline, and at years 1 and 2. Adverse events will be monitored throughout the study.
