Aim. As optimal therapy for irritable bowel syndrome (IBS) remains elusive, current approach to therapy is based on symptomatic treatment. With this case-control experience we wanted to determine the beneficial effect in IBS patients of a dietary integrator (IBS Active), composed of L-tryptophan, inulin, angelica, vegetal charcoal, vitamin PP, group B vitamins (B1, B2, B6) and probiotics (Lactobacillus sporogenes, Lactobacillus acidophilus, Streptococcus thermophilus).
Methods. The treatment group comprised 37 patients (11 men and 27 women; mean age, 44.3±5.1 years) given IBS Active (440 mg bid) over a mean period of 6 months (range, 5-8). The control group comprised 28 patients (6 men and 22 women; mean age, 48.6±3.7 years) who were instructed to continue their customary therapy for 6 months (range, 5-7). All subjects were assessed for the presence of abdominal pain and/or distension, constipation, diarrhea and alternating constipation and diarrhea.
Results. Compared with baseline values, the reduction in abdominal pain in the treatment group was 62% (P<0.0001), 55% (P<0.0001) in abdominal distension, 58% (P=0.05) in constipation, 33% (P=0.3) in diarrhea, and 62% (P=0.01) in alternation constipation and diarrhea. Compared with baseline values, no statistically significant reduction in symptoms was found in the control group. Post-treatment comparison between the two groups showed that the study product had reduced symptoms and that the difference was statistically significant for abdominal pain (P<0.000001), abdominal distension (P=0.003) and constipation (P=0.03).
Conclusions. The use of IBS Active led to a significant improvement in pain symptoms, abdominal distension and regulation of bowel movement in IBS patients. Further study is needed to evaluate the long-term benefit of the study product.
