摘要

Aim. To study the effectiveness of the combined probiotic Bifiform and the enzyme lactase in the treatment of secondary lactase deficiency (SLD). Materials and methods. We examined 79 patients with SLD, isolated from the group of patients with post-infectious irritable bowel syndrome (IBS) with a predominance of diarrhea. The age of patients reached 273.5 years, women predominated by gender 62%. Diagnosis of SLD was carried out in biopsies of the small intestine mucosa using a color rapid test. To diagnose small intestinal bacterial overgrowth (SIBO) all patients underwent lactulose breath test (LBT) during 2 hours by gas analyzer. All patients with lactase deficiency (LD) were divided into 2 groups: group 1 included 54/79 patients who received the combined probiotic Bifiform (1 capsule per day), group 2 was treated with the enzyme lactase [1 capsule (3450 ME) 3 times a day]. The effectiveness of therapy was evaluated by the dynamics of clinical symptoms, indicators of LBT and the detection of hypolactasia in biopsies of the small intestine mucosa twice, before and 2 weeks after treatment. Results. In the group of patients with LD, as a result of 14-day therapy with the combined probiotic Bifiform, 85.2% showed positive clinical dynamics, the values of SIBO in the small intestine decreased from 5814 to 219 ppm, p0.05, and the activity of the lactase enzyme was completely restored. In 14.8% of patients, LD was preserved against the background of persistent SIBO. In the second group of 25 patients, 84% of patients did not achieve a positive dynamics of the disease as a result of taking the lactase enzyme, and hypolactasia and changes in the lumen microflora of the small intestine were preserved after repeated examination of small intestine biopsies. Recovery of the activity of the lactase enzyme was observed in a small percentage of patients, which was 16%. Conclusion. In 85.2% of patients, as a result of therapy with the combined probiotic Bifiform, the activity of the lactase enzyme was restored, due to the suppression of bacterial contamination in the lumen of the small intestine. Replacement therapy with the enzyme lactase only led to remission of LN in 14.2%, while in the majority 85.8% hypolactasia and SIBO remained. Pathogenetic therapy of LN in the adult population includes the appointment of a combined probiotic Bifiform 1 capsule 3 times a day, a course of at least 14 days. As a symptomatic therapy for LN, replacement therapy with the enzyme lactase can be prescribed.
