Assessment of the Adjuvant Role of Dietary Supplementation of Antibiotic-tolerant Probiotics in Standard Therapy for the Eradication of Helicobacter Pylori Infection.

Overview

Randomized, double-blind, placebo-controlled clinical study to assess the adjuvant role of dietary supplementation of antibiotic-tolerant probiotics, derived from Lactobacillus acidophilus and Bifidobacterium animalis, in standard therapy for the eradication of Helicobacter pylori infection.

Randomized, double-blind, placebo-controlled clinical study to assess the adjuvant role of dietary supplementation of antibiotic-tolerant probiotics, in standard therapy for the eradication of H. pylori infection. The aim of this study is to evaluate the antibiotic adverse events decrease in subjects under the standard therapy for H. Pylori eradication using probiotics, compared to patients receiving the same antibiotic therapy with placebo. This study is aimed to (naive) patients who have never received the eradication therapy. The infection of H. Pylori will be analyzed using Urea Breath Test, esophagogastroduodenoscopy (EGDS), Histological and/or culture examination on biopsy samples. The incidence and severity of the adverse events related to the eradication therapy will be assessed through the evaluation questionnaire EACTE (Eventi Avversi Correlati con la Terapia Eradicante) - Adverse Events correlated to Eradication Therapy. The differences of Gastrointestinal Symptom Rating Scale (GSRS) score will be recorded to compare the two groups (patients under antibiotic therapy and probiotics/placebo treatment). The study will involve 270 patients affected by H. pylori, with 1:1 ratio of probiotic/placebo treatment. Each enrolled and randomized patient should take daily: Probiotics or Placebo, depending on the treatment group assigned by randomization, (1 capsule twice a day before breakfast and dinner) for 10 days, before beginning eradication therapy. After the first 10 days of dietary supplementation with probiotics or placebo, the patient will be accompanied by dietary supplementation with eradication therapy (duration 10 days). At the end of the eradication therapy, the patient will continue feeding only probiotics or placebo for a further 4 weeks, with a dosage similar to that used before the beginning of the eradication therapy. On the occasion of the T1 visit (after 20 days from T0 and to complete the eradication therapy), the following will be carried out: * completion by the medical investigator of the EACTE questionnaire, on the basis of the patient's reports on any adverse events occurring during the study and related to eradication therapy, for the period between T0 and T1; * check that the patient has taken the eradication therapy as indicated; * registration of concurrent processing; * recording of adverse events. During the T2 visit (4 weeks after the end of the eradication therapy), the following will be carried out: * urea breath test for the evaluation of HP eradication * administration by the investigator of a questionnaire for the assessment of symptoms of functional dyspepsia, to be completed at T2 (GSRS questionnaire). * recording of adverse events * study conclusion Since this is a double-blind study, neither the doctor nor the patient will be aware of the nature of dietary supplementation (probiotic or placebo) assigned to the patient at T0.
