Celiac Disease Prevention With Probiotics (CiPP)

November 17, 2021 updated by: Lund University

Background/Aim: Celiac disease is a common immune-mediated disorder, and the only currently available treatment is a gluten-free diet. Recent studies have shown several probiotics to carry properties that might positively influence the immunological activity in celiac patients.

The aim of the present study is to investigate how daily consumption of probiotics would affect levels of tissue transglutaminase autoantibodies (tTGA), markers of celiac disease autoimmunity in the periphery, as compared to placebo in children at genetic risk for celiac disease.

Methods: Between 2012 and 2015, 90 children were recruited from two ongoing prospective celiac disease screening studies at the Skåne University Hospital, Sweden. Participants were randomized to either daily consumption of 2 lactobacilli strains or placebo for the duration of 6 months.

Blood samples were drawn at 0, 3 and 6 months and analyzed for both IgA-tTGA and IgG-tTGA using radioligand binding assays.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Probiotic Group

The participants in the Probiotic group were provided with dietary supplements in the form as sachets with freeze dried bacteria (active lactobacilli culture) mixed with maltodextrin for daily intake (1 per day). The powder was dissolved in water or other non-alcoholic cold drink mixed with fruit before ingestion.

The probiotic product consisted of two different bacterial strains.
Dietary supplement: Probiotic
Placebo Comparator: Placebo Group
The participants in the Placebo group were provided with dietary supplements in the form as sachets with maltodextrin for daily intake (1 per day).
Dietary supplement: Placebo
