ReviewProbiotics in the prevention and treatment of gastrointestinal infections.
Probiotics have been studied in a variety of GI infections, and are an appealing concept given their favorable safety profiles. Several placebo-controlled trials indicated that lactobacilli have a suppressive effect on H pylori infection. Although some studies reported improvement in H pylori eradication, others failed to confirm this. ⋯ Studies of probiotics for the prevention of traveler's diarrhea yielded conflicting results, and their routine use cannot be recommended in this setting. Preliminary evidence suggests a potential role for reducing secondary pancreatic infections, although conclusive evidence is not available at this time. Additional clinical trials are indicated to define the role of probiotics further before wide-spread use can be recommended.
