Effects of Probiotic Supplementation during Chronic Rhinosinusitis on the Microbiome.

Abstract

Probiotics are live microorganisms that induce health benefits to the host. The consumption of probiotics can result in both prophylactic and therapeutic effects. Chronic rhinosinusitis (CRS) is an inflammatory condition that has a significant health and economic impact worldwide. Despite its great burden on the health-care system and patients' quality of life, the variety of therapy options for CRS is currently limited. Inflammation, mucociliary dysfunction and changes in the microbial environment are thought to be the main factors causing the disease. Probiotics are a relatively new intervention, with a focus on the probiotic qualities and adaptive elements required for a bacterial strain to have a positive impact on CRS. The aim of this review was to review studies evaluating the potential beneficial effects of probiotics in the treatment of chronic rhinosinusitis. Future prospects and difficulties for probiotics in CRS are also highlighted.
