A Review of Antibiotic Efficacy in COVID-19 Control.

Severe acute respiratory disease is associated with chronic secondary infections that exacerbate symptoms and mortality. So far, many drugs have been introduced to treat this disease, none of which effectively control the coronavirus. Numerous studies have shown that mitochondria, as the center of cell biogenesis, are vulnerable to drugs, especially antibiotics. Antibiotics were widely prescribed during the early phase of the pandemic. We performed a literature review to assess the reasons, evidence, and practices on the use of antibiotics in coronavirus disease 2019 (COVID-19) in- and outpatients. The current research found widespread usage of antibiotics, mostly in an empirical context, among COVID-19 hospitalized patients. The effectiveness of this approach has not been established. Given the high death rate linked with secondary infections in COVID-19 patients and the developing antimicrobial resistance, further study is urgently needed to identify the most appropriate rationale for antibiotic therapy in these patients.

Investigation of microbial coinfection in 453 septic COVID-19 patients admitted to hospital; a retrospective study.

Aim: We evaluated the rate of COVID-19 microbial coinfection in an Iranian population. Methods: In this single-center, retrospective observational study, we evaluated 453 septic COVID-19 patients for possible coinfection in an Iranian hospital. Results: Overall, 211 (46.57%) cases died due to COVID-19 complications. Positive respiratory secretion and blood cultures were reported in 99 (21.9%) and 19 (4.2%) cases. Klebsiella species were the most commonly isolated microorganisms in respiratory (n = 50, 50.5%) and blood (n = 10, 52.6%) specimens. After adjustment for underlying disorders, positive respiratory microbial cultures significantly increase the odds of developing death, intubation, and ICU admission and negatively impact healthy discharge (P < 0.05). Conclusion: Coinfections with bacteria and fungi independently contribute to poor outcomes in septic COVID-19 patients.

COVID-19 bacterial/fungal coinfection is associated with severe mortality rates as it complicates the primary viral infection. This study evaluated 453 patients admitted to an Iranian hospital with COVID-19 and concomitant sepsis for microbial coinfection. A total of 99 (21.9%) cases had positive respiratory secretion cultures, and 19 (4.2%) had positive blood cultures. Klebsiella species were the most commonly yielded microorganism in both respiratory (n = 50, 50.5%) and blood (n = 10, 52.6%) specimens. Bacterial and fungal microbial coinfection are independent determinants of poor outcomes in septic COVID-19 cases.
