What this trial studies

This randomized, double-blind, placebo-controlled study aims to assess the effectiveness of Skål Pro powder, which contains Lactobacillus plantarum 299v, in alleviating symptoms of irritable bowel syndrome (IBS). The study will compare the outcomes of participants receiving the probiotic treatment against those receiving a placebo. It focuses on improvements in stool consistency, quality of life, and psychological distress among individuals diagnosed with IBS, particularly within the Malaysian population. The research seeks to clarify the unique mechanisms of the probiotic strain in this demographic.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old diagnosed with any subtype of irritable bowel syndrome according to the Rome IV criteria.

Not a fit: Patients with severe underlying medical conditions, recent antibiotic use, or specific psychiatric disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients suffering from irritable bowel syndrome.

How similar studies have performed: Previous studies have shown promise in using probiotics for IBS treatment, but the specific efficacy of Lactobacillus plantarum 299v remains to be fully established.
