Unravelling the potential of synbiotics in ameliorating COVID-19 complications: A concise review

Abstract

The ongoing COVID-19 pandemic has highlighted the need for innovative strategies to mitigate the severe complications associated with infection caused by SARS-CoV-2. Developing empirical studies posited that the gut microbiota play a key role in modulating the immune response and overall health. This review explores the potential of synbiotics, a combination of probiotics and prebiotics, as a promising therapeutic approach to ameliorate COVID-19 complications. We conducted a comprehensive review of the literature to assess the impact of synbiotics on key aspects of the pathogenesis of this disease. Several studies indicate that synbiotics can bolster the gut microbiome, enhance mucosal barrier function, and regulate the immune system. These effects may be particularly beneficial in COVID-19, where immune dysregulation and cytokine storm are implicated in severe disease. We discuss the mechanisms through which synbiotics influence the gut axis, modulating the immune response and potentially reducing the risk of acute respiratory distress syndrome and other complications. Furthermore, synbiotics may help manage gastrointestinal symptoms often associated with COVID-19 and support the recovery of patients. While current research is promising, further clinical trials are needed to validate the safety and efficacy of synbiotics in the context of COVID-19. This review underscores the potential of synbiotics as an adjunctive therapy to conventional treatments for COVID-19, offering a novel and integrated approach to improve patient outcomes and reduce the burden of this health challenge worldwide.
