The immunological response among COVID-19 patients with acute respiratory distress syndrome

Potential Drugs in COVID-19 Management

The SARS-CoV-2 virus first emerged in China in December 2019 and quickly spread worldwide. Despite the absence of a vaccination or authorized drug specifically developed to combat this infection, certain medications recommended for other diseases have shown potential effectiveness in treating COVID-19, although without definitive confirmation. This review aims to evaluate the existing literature on the efficacy of these medications against COVID-19. The review encompasses various potential treatments, including antiviral medications, anti-malaria and anti-rheumatic drugs, vaccines, corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs), antipyretic and analgesic medicines, antiparasitic drugs, and statins. The analysis also addresses the potential benefits and drawbacks of these medications, as well as their effects on hypertension and diabetes. Although these therapies hold promise against COVID-19, further research, including suitable product production or clinical testing, is needed to establish their therapeutic efficacy.

Evidence mapping and review of long-COVID and its underlying pathophysiological mechanism

PURPOSE

Apart from the global disease burden of acute COVID-19 disease, the health complications arising after recovery have been recognized as a long-COVID or post-COVID-19 syndrome. Evidences of long-COVID symptoms involving various organ systems are rapidly growing in literature. The objective was to perform a rapid review and evidence mapping of systemic complications and symptoms of long-COVID and underlying pathophysiological mechanisms.

METHODS

Publications reporting clinical trials, observational cohort studies, case-control studies, case-series, meta-analysis, and systematic reviews, focusing on the squeal of the disease, consequences of COVID-19 treatment/hospitalization, long-COVID, chronic COVID syndrome, and post acute COVID-19 were reviewed in detail for the narrative synthesis of frequency, duration, risk factors, and pathophysiology.

RESULTS

The review highlights that pulmonary, neuro-psychological, and cardiovascular complications are major findings in most epidemiological studies. However, dysfunctional gastrointestinal, endocrine, and metabolic health are recent findings for which underlying pathophysiological mechanisms are poorly understood. Analysis of the clinical trial landscape suggests that more than 50% of the industry-sponsored trials are focused on pulmonary symptoms. In contrast to the epidemiological trends and academic trials, cardiovascular complications are not a focus of industry-sponsored trials, suggestive of the gaps in the research efforts.

CONCLUSION

The gap in epidemiological trends and academic trials, particularly concerning cardiovascular complications not being a focus of industry-sponsored trials is suggestive of the gaps in research efforts and longer follow-up durations would help identify other long-COVID-related health issues such as reproductive health and fertility.

Effects of corticosteroids on Covid-19 patients: A systematic review and meta-analysis on clinical outcomes

BACKGROUND

Covid-19 disease is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although corticosteroids have shown some promising results in Covid-19 patients, their effectiveness remains controversial. In this systematic review, we evaluated the effect of corticosteroids in mortality, Hospitalization, ICU admission, intubation, and mechanical ventilation in Covid-19 patients.

METHODS

We searched major databases from March-2020 to Jan-2021. Twenty-nine studies were included after evaluating the eligibility of the literature. The extracted data for mortality, hospitalization, admission to the ICU, intubation, and mechanical ventilation were analyzed with RevMan® 5.4. Categorical variables are presented with odds ratios (OR), and numerical variables are shown with the mean difference.

RESULT

Corticosteroid treatment had no impact on mortality in 18,190 covid patients with OR = 1.12[0.83-1.50]. When we include the randomized controlled trials, corticosteroids reduced the mortality by 20% (OR = 0.80 [0.73, 0.88]; P < 0.001). Additionally, the risk of admission to the ICU, the need for endotracheal intubation, and mechanical ventilation were comparable between patients receiving corticosteroids and controls. The duration of hospitalization was also similar in the two groups.

CONCLUSION

Corticosteroid therapy may not be effective for reducing mortality, length of hospitalization, the likelihood of intubation and mechanical ventilation, and ICU admission in patients suffering from Covid-19 pneumonia.
