Effects of the supplementation with a multispecies probiotic on clinical and laboratory recovery of children with newly diagnosed celiac disease: A randomized, placebo-controlled trial.

OBJECTIVE

To evaluate the efficacy of a multispecies probiotic on clinical and laboratory recovery of children with celiac disease (CeD) at diagnosis.

METHODS

Children with newly diagnosed CeD entered a randomized double-blind placebo-controlled trial. A gluten-free diet (GFD) plus a multispecies probiotic or placebo were administered for 12 weeks. Growth, laboratory, and clinical parameters were recorded at enrollment, after 3 and 6 months of follow-up.

RESULTS

Overall, 96 children completed the study: 49 in group A (placebo) and 47 in group B (probiotic). A significant increase of BMI-Z score was found in both groups after 3 and 6 months of treatment (p < 0.001), however the increase of BMI-Z score was significantly higher and faster in Group B than in Group A. Other clinical and laboratory parameters improved in both groups after 3 and 6 months (p<0.001), but no difference was found between the groups and a comparable time trend was observed in both groups.

CONCLUSIONS

Treatment with a multispecies probiotic induced a higher and faster increase of BMI in children with newly diagnosed CeD. The mechanism of this positive effect remains to be elucidated.
