Abstract
The treatment of coronavirus disease (COVID-19) and COVID-19-associated diarrhea remains challenging. This study aimed
to evaluate the efficacy of a multi-strain probiotic in the treatment of COVID-19. This was a randomized, controlled, singlecenter, open-label trial (NCT04854941). Inpatients with confirmed COVID-19 and pneumonia were randomly assigned to a
group that received a multi-strain probiotic (PRO group) or to the control group (CON group). There were 99 and 101 patients
in the PRO and CON groups, respectively. No significant differences in mortality, total duration of disease and hospital stay,
incidence of intensive care unit admission, need for mechanical ventilation or oxygen support, liver injury development, and
changes in inflammatory biomarker levels were observed between the PRO and CON groups among all included patients as
well as among subgroups delineated based on age younger or older than 65 years, and subgroups with chronic cardiovascular
diseases and diabetes. Diarrhea on admission was observed in 11.5% of patients; it resolved earlier in the PRO group than
in the CON group (2 [1–4] vs. 4 [3–6] days; p = 0.049). Hospital-acquired diarrhea developed less frequently in the PRO
group than in the CON group among patients who received a single antibiotic (0% vs. 12.5%; p = 0.023) unlike among those
who received > 1 antibiotic (10.5% vs. 13.3%; p = 0.696). The studied probiotic had no significant effect on mortality and
changes in most biomarkers in COVID-19. However, it was effective in treating diarrhea associated with COVID-19 and in
preventing hospital-acquired diarrhea in patients who received a single antibiotic.
