简要总结
The objective of the study is to develop a probiotic product (B. longum CCT 1934; B. lactis CCT 7858; L. rhamnosus CCT 7863; S. thermophilus ATCC 19258) to reduce the symptoms caused by celiac disease and concomitantly improve the quality of life of patients. To achieve the objective, 118 volunteers of both sexes will be included, randomly distributed into two groups: Test group (n=59): Volunteers supplemented with the probiotic product (Bifidobacterium longum CCT 1934; Bifidobacterium lactis CCT 7858; Lactobacillus rhamnosus CCT 7863 ; Streptococcus thermophilus ATCC 19258) Final concentration: 1 x 1010 CFU/ day) and Placebo group (n=59): Volunteers supplemented with placebo. The study will be conducted with patients diagnosed with celiac disease, the audience is adults (18 - 65 years old). The study will last for 90 days and volunteers will be invited to participate in three visits. During these visits, participants will be invited to answer the proposed questionnaires. The volunteer is expected to show improvement in gastrointestinal symptoms, as well as an improvement in quality of life after using the probiotic blend for 90 days.
