ABSTRACT
Background: Neurological disability associated with multiple sclerosis and immunosuppressive or immunomodulatory therapy which is administered for it may increase the risk of SARS-CoV-2 infection and its morbidity/mortality. In this study, we evaluated the severity of SARS-CoV-2 infection in patients with multiple sclerosis based on their demographic and disease data. Methods: A total of 1361 multiple sclerosis patients from Fars province were interviewed by phone from April 3 to June 20, 2020. Basic demographic data, information about their disease and any symptoms or laboratory results relevant to COVID-19 were gathered. Results: Among the studied patients, 68 ones (5%) were COVID-19 suspected cases and 8 ones (0.58%) were in the confirmed group. Five cases in the confirmed group needed hospitalization. Two patients died while both of them were taking rituximab. The frequency rate of suspected cases with RRMS was 57 (87.7%), followed by 5 (7.7%) PPMS and 2 (3.1%) CIS. In the confirmed group, 25% used corticosteroid drug and 50% were on rituximab;moreover, 62.5% of the confirmed cases had a high disability level and needed assistance to walk. In whole, 36.8% of the suspected and 25% of the confirmed cases were on IFN-β1;eventually, all of them recovered well from COVID-19 infection. Conclusion: In the present study, the rate of developing COVID-19 in multiple sclerosis patients was similar to the general population and most of patients with multiple sclerosis recovered from COVID-19 without referral to a medical specialist. © 2021, Kerman University of Medical Sciences.

ABSTRACT
Since December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged and spread quickly worldwide. The disease is generally mild in adult people but in any with comorbidities may proceed to acute respiratory distress syndrome (ARDS), pneumonia, and multi-organ dysfunction. By performing molecular tests on respiratory secretions can diagnose the virus. Elevated C-reactive protein (CRP) and normal/low white cell counts are common laboratory diagnoses of COVID-19 while the tomographic chest scan is usually irregular for many infected people. Some patients progress to respiratory failure, pneumonia, and finally death by the end of the first week of illness because of the sharp rise in inflammatory cytokines such as IL7, IL2, GCSF, IL10, MIP1A, MCP1, IP10, and TNFα. Various approaches to the COVID- 19 are being performed by scientists. Use of chemical medical drugs that are effective for other viral infections. Among them, remdesivir was approved by FDA on 1th May 2020 because of its impact to treat patients. Also, several studies have revealed that many Chinese herbal remedies have a remarkable impact on the healing process when simultaneously were used along with pharmacological drugs. In the meantime, many efforts have been made to produce an effective vaccine, and so far, the Ad5-vectored COVID-19 vaccine has been successful and has entered phase 2 in the human trial. The current review focus on epidemiology, virology, clinical features, diagnosis, and available treatment of coronavirus that might assist researchers and clinicians in establishing action options for timely against this infection.
ABSTRACT
After the advent of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) in the late 2019, the resulting severe and pernicious syndrome (COVID-19) immediately was deployed all around the world. To date, despite relentless efforts to control the disease by drug repurposing, there is no approved specific therapy for COVID-19. Given the role of innate and acquired immune components in the control and elimination of viral infections and inflammatory mutilations during SARS-CoV2 pathogenesis, immunotherapeutic strategies appear to be beneficent. Passive immunotherapies such as convalescent plasma, which has received much attention especially in severe cases, as well as suppressing inflammatory cytokines, interferon administration, inhibition of kinases and complement cascade, virus neutralization with key engineered products, cell-based therapies, immunomodulators and anti-inflammatory drugs are among the key immunotherapeutic approaches to deal with COVID-19, which is discussed in this review. Also, details of leading COVID-19 vaccine candidates as the most potent immunotherapy have been provided. However, despite salient improvements, there is still a lack of completely assured vaccines for universal application. Therefore, adopting proper immunotherapies according to the cytokine pattern and involved immune responses, alongside engineered biologics specially ACE2-Fc to curb SARS-CoV2 infection until achieving a tailored vaccine is probably the best strategy to better manage this pandemic. Therefore, gaining knowledge about the mechanism of action, potential targets, as well as the effectiveness of immune-based approaches to confront COVID-19 in the form of a well-ordered review study is highly momentous.
