Current status of probiotics to treat gastrointestinal infections
There have been lots of posts here on probiotics and their effects in a wide range of infections of the GI tract. Probiotics are an appealing concept given their favorable safety profiles.
Now, a summary of clinical trials has been published.
Here are the findings.
- Some placebo-controlled trials show that lactobacilli suppress infections caused by Helicobacter pylori, but others fail to confirm this.
- Controlled trials support the use of Lactobacillus GG and Saccharomyces boulardii to prevent antibiotic-associated diarrhea, and the effectiveness of S boulardii used as add-on therapy for recurrent infections.
- Several placebo-controlled trials show that Lactobacillus GG reduces the severity and duration of acute diarrhea in children.
- Studies of probiotics to prevent traveler’s diarrhea report conflicting results, and their routine use cannot be recommended in this setting.
- Conclusive evidence that probiotics prevent secondary pancreatic infections is not available at this time.
