Abstract

BACKGROUND

Gastroenteritis is a common and impactful disease in childhood. Probiotics are often used to treat acute gastroenteritis (AGE); however, in a large multicenter randomized controlled trial (RCT) in 971 children, Lactobacillus rhamnosus GG (LGG) was no better than placebo in improving patient outcomes.

OBJECTIVES

We sought to determine whether the effect of LGG is associated with age, weight z score and weight percentile adjusted for age and sex, or dose per kilogram administered.

METHODS

This was a preplanned secondary analysis of a multicenter double-blind RCT of LGG 1 × 1010 CFU twice daily for 5 d or placebo in children 3-48 mo of age with AGE. Our primary outcome was moderate to severe gastroenteritis. Secondary outcomes included diarrhea and vomiting frequency and duration, chronic diarrhea, and side effects. We used multivariable linear and nonlinear models testing for interaction effects to assess outcomes by age, weight z score and weight percentile adjusted for age and sex, and dose per kilogram of LGG received.

RESULTS

A total of 813 children (84%) were included in the analysis; 413 received placebo and 400 LGG. Baseline characteristics were similar between treatment groups. There were no differential interaction effects across ranges of age (P-interaction = 0.32), adjusted weight z score (P-interaction = 0.43), adjusted weight percentile (P-interaction = 0.45), or dose per kilogram of LGG received (P-interaction = 0.28) for the primary outcome.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 971 participants or records.
