Does probiotic supplementation improve quality of life in mild-to-moderately active ulcerative colitis patients in Jordan? A secondary outcome of the randomized, double-blind, placebo-controlled study.

PURPOSE

Recent findings revealed a potential effect of a probiotic in improving quality of life (QoL) in ulcerative colitis (UC). In Jordan, there is scarce data about UC patients and QoL.

METHODS

Twenty-four UC patients were included in the study and were randomly allocated into probiotic (3 × 10 probiotic capsules containing nine Lactobacillus and five Bifidobacterium species) and placebo control groups (containing polysaccharide supplied in an identical bottle) 3 times daily/6 weeks. A short inflammatory bowel disease questionnaire (SIBDQ) was used to assess the change in the quality of life in both groups at the beginning and the end of the intervention; The study was completed during the COVID-19 pandemic.

RESULTS

Patients treated with probiotics showed a higher score of social (6.92 ± 0.29, p = 0.019), bowel (6.31 ± 0.46, p = 0.001), emotional (6.47 ± 0.46, p < 0.001), and total SIBDQ scores (6.54 ± 0.29, p < 0.001) compared to the placebo group (5.75 ± 1.57, 4.72 ± 1.34, 4.42 ± 1.67 and 4.96 ± 1.27; respectively). Also, the probiotic group had significantly better scores in the systemic, social, bowel, emotional, and total SIBDQ scores in terms of pre- to post-treatment (p < 0.001).

CONCLUSIONS

The use of probiotic therapy containing Lactobacillus and Bifidobacterium species had significantly improved the quality of life among UC patients, this was shown by the improvement in the scores of the systemic domain, social domain, bowel domain, emotional domain, and total SIBDQ. This study is part of a registered study at ClinicalTrials.gov with the number NCT04223479.
