Trials of tocilizumab in patients with severe COVID-19 pneumonia have demonstrated mixed results, and the role combination other treatments is uncertain. Here we evaluated whether plus remdesivir provides greater benefit than alone pneumonia. This randomized, double-blind, placebo-controlled, multicenter trial included hospitalized requiring > 6 L/min supplemental oxygen. Patients were randomly assigned (2:1 ratio) to receive 8 mg/kg or placebo intravenously ≤ 10 days remdesivir. The primary outcome was time from randomization hospital discharge "ready for discharge" (defined as category 1, assessed by investigator on a 7-category ordinal scale clinical status) day 28. followed 60 days.

Abstract The Coronavirus Disease 2019 (COVID-19) pandemic has become a global crisis and is more devastating than any other previous infectious disease. It affected significant proportion of the population both physically mentally, destroyed businesses societies. Current evidence suggested that immunopathology may be responsible for COVID-19 pathogenesis, including lymphopenia, neutrophilia, dysregulation monocytes macrophages, reduced or delayed type I interferon (IFN-I) response, antibody-dependent enhancement, especially, cytokine storm (CS). CS characterized by hyperproduction an array pro-inflammatory cytokines closely associated with poor prognosis. These excessively secreted initiate different inflammatory signaling pathways via their receptors on immune tissue cells, resulting in complicated medical symptoms fever, capillary leak syndrome, disseminated intravascular coagulation, acute respiratory distress multiorgan failure, ultimately leading to death most severe cases. Therefore, it clinically important understand initiation develop effective treatment strategies COVID-19.

Immune-related manifestations are increasingly recognized conditions in patients with COVID-19, around 3,000 cases reported worldwide comprising more than 70 different systemic and organ-specific disorders. Although the inflammation caused by SARS-CoV-2 infection is predominantly centred on respiratory system, some can develop an abnormal inflammatory reaction involving extrapulmonary tissues. The signs symptoms associated this excessive immune response very diverse resemble autoimmune or diseases, clinical phenotype that seemingly influenced epidemiological factors such as age, sex ethnicity. severity of also varied, ranging from benign self-limiting features to life-threatening syndromes.

To add to this burden, sizeable subset patients who have recovered from acute COVID-19 infection reported lingering symptoms, leading significant disability and impairment their daily life activities. These are considered suffer what has been termed as “chronic” or “long” form post-acute sequelae COVID-19, experiencing syndrome long-haulers. Despite recovery infection, the persistence atypical chronic including extreme fatigue, shortness breath, joint pains, brain fogs, anxiety depression, that could last for months implies an underlying pathology persist beyond presentation disease.

In life-threatening coronavirus disease (COVID-19), corticosteroids reduce mortality, suggesting that immune responses have a causal role in death. Whether this deleterious inflammation is primarily direct reaction to the presence of severe acute respiratory syndrome 2 (SARS-CoV-2) or an independent immunopathologic process unknown.

Hospitalised patients with coronavirus disease 2019 (COVID-19) as a result of SARS-CoV-2 infection have high mortality rate and frequently require noninvasive respiratory support or invasive ventilation. Optimising standardising management through evidence-based guidelines may improve quality care therefore patient outcomes.A task force from the European Respiratory Society endorsed by Chinese Thoracic identified priority interventions (pharmacological non-pharmacological) for initial version this "living guideline" using PICO (population, intervention, comparator, outcome) format. The GRADE approach was used assessing evidence strength recommendations. Systematic literature reviews were performed, data pooled meta-analysis where possible. Evidence tables presented to decision frameworks formulate recommendations.Based on available at time guideline development (20 February, 2021), panel makes strong recommendation in favour use systemic corticosteroids requiring supplementary oxygen ventilatory support, anticoagulation hospitalised patients. conditional interleukin (IL)-6 receptor antagonist monoclonal antibody treatment high-flow nasal continuous positive airway pressure hypoxaemic failure. make recommendations against hydroxychloroquine lopinavir-ritonavir.
