Probiotics for Preventing ICU-Acquired Infections in Critically Ill Patients: A Pilot Study

This pilot randomized clinical trial investigated the effect of probiotic supplementation on the incidence of intensive care unit-acquired infections (ICU-AIs) in critically ill patients. ICU-AIs are a major complication in patients receiving mechanical ventilation and enteral nutrition, contributing to increased morbidity, prolonged ICU length of stay, and higher mortality rates. The objective of this study was to assess whether daily administration of a probiotic supplement, in addition to standard ICU care, could reduce the risk of ICU-AIs compared with standard care alone. Eligible participants were critically ill adults who were mechanically ventilated and receiving enteral feeding. Patients were randomly assigned to one of two groups: Control group: standard ICU care. Intervention group: standard ICU care plus probiotic supplementation (Biopro-max 8 Billion Probiotics (Bioserv Healthcare)). The intervention continued for 15 days, during which participants were monitored daily for the occurrence of ICU-AIs confirmed by the treating ICU physician. Secondary outcomes included inflammatory and immune markers (CRP, PCT, IgG, IgA), tolerance to enteral feeding, skeletal muscle changes assessed by point-of-care ultrasound, ICU and hospital length of stay, and mortality.
