Post-discharge health assessment in survivors of coronavirus disease: a time-point analysis of a prospective cohort study.

PURPOSE:  The objective of this study was to quantitatively evaluate psychological and quality of life-related complications at three months following discharge in hospitalized coronavirus disease 2019 (COVID-19) patients during the pandemic in Iran. METHODS: In this time-point analysis of prospective cohort study data, adult patients hospitalized with symptoms suggestive of COVID-19 were enrolled. Patients were stratified in analyses based on severity. The primary outcomes consisted of psychological problems and pulmonary function tests (PFTs) in the three months following discharge, with Health-related quality of life (HRQoL) as the secondary outcome. Exploratory predictors were determined for both primary and secondary outcomes. RESULTS: 283 out of 900 (30%) eligible patients were accessible for the follow-up assessment and included in the study. The mean age was 53.65 ± 13.43 years, with 68% experiencing a severe disease course. At the time of the final follow-up, participants still reported persistent symptoms, among which fatigue, shortness of breath, and cough were the most common. Based on the regression-adjusted analysis, lower levels of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) ratio was associated with higher levels of depression (standardized ß = - 0.161 (SE = 0.042), P = 0.017) and stress levels (standardized ß =- 0.110 (SE = 0.047), P = 0.015). Furthermore, higher levels of anti-SARS-CoV-2 immunoglobulin-M (IgM) were associated with significantly lower levels of depression (standardized ß = - 0.139 (SE = 0.135), P = 0.031). CONCLUSIONS: There is an association between lung damage during COVID-19 and the reduction of pulmonary function for up to three months from acute infection in hospitalized patients. Varying degrees of anxiety, depression, stress, and low HRQoL frequently occur in patients with COVID-19. More severe lung damage and lower COVID-19 antibodies were associated with lower levels of psychological health.

Safety of Sinopharm vaccine for people with Multiple Sclerosis: Study of adverse reactions and disease activity.

BACKGROUND: The aim of this study was to evaluate the safety of Sinofarm vaccine (BBIBP-CorV) in patients with multiple sclerosis (pwMS). METHODS: This study was conducted on pwMS patients in Isfahan, Iran. All participants received two doses of BBIBP-CorV (Sinopharm vaccine). Demographic information and data on vaccine side effects were collected after each dose using questionnaires. All patients that recorded worsening of MS symptoms were evaluated and those with true relapse were treated with IV methyl prednisolone. RESULTS: Of the 1538 patients, 1151 (74.8%) were female and the mean age was 40.45 ± 9.74. The average disease duration was 10.38±6.81 years and 76.1% of participants had RRMS. 92.8% of the participants were using DMTs and mean EDSS was 2.06 ± 3.16. 54.2% (833 patient) reported at least one adverse event after the first dose of vaccine and 46.8% (720 patient) after the second dose; in both cases going away in a few days. Most prevalent adverse events after both doses were injection site pain, headache, myalgia, fever and fatigue. Adverse events were more prevalent in younger and less prevalent in mildly disabled patients. There were seven cases of Covid-19 infection between the first and second vaccination dose, and eight cases during one-month follow -up after the second dose, none of whom needed mechanical ventilation. Ten patients after first dose and thirteen patients after the second dose experienced acute relapse. A patient had two relapses, one after each vaccine dose that were clinically and radiologically confirmed. The first relapse occurred seven days after the first vaccination with hemiparesis and other relapse, 14 days after the second dose with diplopia, hemiparesis and ataxia. CONCLUSION: Adverse events in pwMS following vaccination with Sinopharm vaccine was similar to the general population, which were more common in younger patients and less common in those with mild disability. As no increase in relapse rate after vaccination was detected, Sinopharm vaccine was safe in MS patients.

COVID-19 infection and hospitalization rate in Iranian multiple sclerosis patients: What we know by May 2021.

BACKGROUND: Despite investigations on the effect of disease modifying therapies (DMTs) used in multiple sclerosis (MS) on coronavirus disease 2019 (COVID-19); there are still controversies. OBJECTIVE: We designed this study to evaluate the epidemiological features of covid-19 in a large sample of people with MS (pwMS) in Isfahan, Iran, as well as the association between DMTs, risk of COVID-19 infection and hospitalization. METHODS: In an observational pwMS, we interviewed subjects on their MS and COVID-19 history. RESULTS: 3050 subjects were included (74% female) with a mean age of 41.36. 423 (13.8%) had confirmed COVID-19 which shows that pwMS are at a higher risk of infection compared to the general population, No significant relationship was observed in COVID-19 infection when individual drugs. Dimethyl fumarate and rituximab had the lowest and the highest relative risks for hospitalization rate compared to other drugs, respectively. CONCLUSION: We found no evidence supporting a higher prevalence of COVID-19 in pwMS compared to the general population. However, our results show pwMS to be more prone to hospitalization compared to the general population, Therefore, it is advised to use safer treatment if possible until complete vaccination, and to postpone the use of rituximab.
