Abstract
Background:
Patients with irritable bowel syndrome (IBS) experience recurrent symptoms and anxiety disorders that significantly impact their quality of life (QoL). The aim of the study was to assess in daily practice the benefit of the combination of three probiotic strains (Lactobacillus plantarum CETC 7484 and CETC 7485; Pediococcus acidilactici CECT 7483) plus vitamin D in patients with diarrhea-predominant IBS (IBS-D) or IBS with mixed bowel movements (IBS-M).
Methods:
This was a prospective, multicenter, non-interventional study in adult patients with IBS-D or IBS-M (Rome IV criteria) followed by private-practice gastroenterologists. Patients received daily one sachet of a combination of probiotics (3×109 CFU) and vitamin D (10 μg) for 42 days. The primary endpoint was the responder rate at D42 (≥50% and/or ≥100-point decrease of IBS-Severity Scoring System; IBS-SSS). Gut-related anxiety was measured with the Visceral Sensitivity Index (VSI).
Results:
The full analysis set population included 246 patients (mean age, 51.2±15.4 years; women, 73.2%; IBS-D, 56.1%; IBS-M, 43.9%). At D42, among the 89 patients with evaluable data, the responder rate was 62.9% with a mean decrease of IBS-SSS of 146.6±125.9 (P<0.0001). Changes of IBS-SSS were significantly correlated with changes of IBS-QoL (r=-0.78; P<0.0001), HAD-anxiety (r=0.46; P<0.0001), HAD-depression (r=0.61; P<0.001) and VSI (r=0.74; P<0.0001).
Conclusions:
These real-life results are in line with a previous randomized clinical trial demonstrating the benefits of this combination in IBS-D and IBS-M. Symptom relief was associated with improvement of IBS-QoL, anxiety, depression and specifically gut-related anxiety.
