COVID-19 Pneumonia and Gut Inflammation

COVID-19 Pneumonia and Gut Inflammation: The Role of a Mix of Three Probiotic Strains in Reducing Inflammatory Markers and Need for Oxygen Support

The primary objective of our study was to evaluate the efficacy of a mix of three probiotic strains (Bifidobacterium lactis LA 304, Lactobacillus salivarius LA 302, and Lactobacillus acidophilus LA 201; Lactibiane Iki®) in the reduction in fecal calprotectin in patients with COVID-19 pneumonia, compared to a control group. The secondary aim was to evaluate the reduction in oxygen support and length of hospital stay in patients taking the probiotic mix.
