Meta AnalysisThe effect of tocilizumab on COVID-19 patient mortality: A systematic review and meta-analysis of randomized controlled trials.
This systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to investigate the clinical efficacy and safety of tocilizumab for treating patients with COVID-19. ⋯ Tocilizumab does not provide a survival benefit for patients with COVID-19, but it may help reduce the risk of MV and ICU admission. In addition, tocilizumab is a safe agent to use for the treatment of COVID-19.

ReviewAn update review of globally reported SARS-CoV-2 vaccines in preclinical and clinical stages.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the rapidly spreading pandemic COVID-19 in the world. As an effective therapeutic strategy is not introduced yet and the rapid genetic variations in the virus, there is an emerging necessity to design, evaluate and apply effective new vaccines. An acceptable vaccine must elicit both humoral and cellular immune responses, must have the least side effects and the storage and transport systems should be available and affordable for all countries. ⋯ According to the latest update of the WHO report on April 2nd, 2021, at least 85 vaccine candidates were being studied in clinical trial phases and 184 candidate vaccines were being evaluated in pre-clinical stages. In addition, studies have shown that other vaccines, including the Bacillus Calmette-Guérin (BCG) vaccine and the Plant-derived vaccine, may play a role in controlling pandemic COVID-19. Herein, we reviewed the different types of COVID-19 candidate vaccines that are currently being evaluated in preclinical and clinical trial phases along with advantages, disadvantages or adverse reactions, if any.

Immune-related adverse events associated with immune checkpoint inhibitors: An updated comprehensive disproportionality analysis of the FDA adverse event reporting system.
Immune-related adverse events were reported in patients treated with immune checkpoint inhibitors (ICIs). However, with the increasing number of immune-related adverse events (irAEs), the differences of each immune checkpoint inhibitor regimen had not been fully assessed. ⋯ Our results demonstrated that each ICI regimen had different characteristics of irAEs. Pembrolizumab had the highest fatality proportion. Ipilimumab plus pembrolizumab had the shortest median time to onset irAEs. Further studies were expected to assess whether there were clinically relevant differences exist among ICIs.

ReviewAdvances in immunotherapy for COVID-19: A comprehensive review.
COVID-19 is an acute respiratory syndrome caused by SARS-COV-2 which has now become a huge pandemic worldwide. The immunopathogenesis of COVID-19 has been established that increased serum levels of C-reactive protein (CRP), interleukin-6 (IL-6), and reduction of the CD4+ and the CD8+ T lymphocyte populations, are the most reported immunological findings in these patients. ⋯ However, specific and non-specific immunotherapies such as convalescent plasma (CP) are widely performed to treat patients with severe COVID-19, there is no definitive evidence to suggest the effectiveness of these treatments. Hence, this review aimed to highlight the current and most recent studies to identify the new immunotherapeutics for COVID-19 disease.

Clinical TrialEfficacy and safety of convalescent plasma therapy in severe COVID-19 patients with acute respiratory distress syndrome.
Since SARS-CoV-2 infection is rapidly spreading all around the world, affecting many people and exhausting health care resources, therapeutic options must be quickly investigated in order to develop a safe and effective treatment. The present study was designed to evaluate the safety and efficacy of convalescent plasma (CP) for treating severe cases of COVID-19 who developed acute respiratory distress syndrome (ARDS). Among 64 confirmed cases of severe COVID-19 with ARDS in this study, 32 patients received CP besides first line treatment. ⋯ Patients with plasma therapy showed improvements in their clinical outcomes including a reduction in disease severity in terms of SOFA and APACHE II scores, the length of ICU stay, need for noninvasive ventilation and intubation and also showed an increase in oxygenation. They also showed reduction in mortality which was statistically significant in less severe cases with mild or moderate ARDS. Early administration of the convalescent plasma could successfully contribute to the treatment of severe COVID-19 patients with mild or moderate ARDS at risk of progressing to critical state.
