Efficacy and Safety of Postbiotic Contained Inactivated Lactobacillus reuteri ( Limosilactobacillus reuteri ) DSM 17648 as Adjuvant Therapy in the Eradication of Helicobacter pylori in Adults With Functional Dyspepsia: A Randomized Double-Blind Placebo-Controlled Trial.

INTRODUCTION: Increasing the effectiveness of eradication therapy is an important task in gastroenterology. The aim of this study was to evaluate the efficacy and safety of postbiotic containing inactivated (nonviable) Limosilactobacillus (Lactobacillus) reuteri DSM 17648 (Pylopass) as adjuvant treatment of Helicobacter pylori eradication in patients with functional dyspepsia (FD). METHODS: This randomized, double-blind, placebo-controlled, multicenter, parallel study included H. pylori -positive patients with FD. The postbiotic group received Pylopass 200 mg bid for 14 days in combination with eradication therapy (esomeprazole 20 mg bid + amoxicillin 1,000 mg bid + clarithromycin 500 mg bid for 14 days) and another 14 days after the completion of eradication therapy. The study was registered in the ISRCTN registry (ISRCTN20716052). RESULTS: Eradication efficiency was 96.7% for the postbiotic group vs 86.0% for the placebo group ( P = 0.039). Both groups showed significant improvements in quality of life and reduction of most gastrointestinal symptoms with no significant differences between groups. The overall number of digestive adverse effects in the postbiotic group was lower than in the placebo group. Serious adverse effects were not registered. DISCUSSION: The postbiotic containing inactivated L. reuteri DSM 17648 significantly improves the effectiveness of H. pylori eradication therapy in FD and decreases overall number of digestive adverse effects of this therapy.

Emergency Splenectomy in a Patient with Splenic Marginal Zone Lymphoma, Acute Portal Vein Thrombosis, and Chronic Viral Hepatitis B.

Splenic marginal zone lymphoma (SMZL) is a type of non-Hodgkin's lymphoma (NL) that occurs in 2 out of 100 cases and is more common in women aged >60 years. A sluggish, asymptomatic course of the disease does not exclude transformation into a malignant form that occurs in 25% of patients with SMZL. Another equally important sign of an NL is thrombosis that occurs in 3.6% to 17.1% of the cases. In this report, we present a case of emergency splenectomy in a patient owing to difficulties in the diagnosis of SMZL, rapid onset of acute portal vein thrombosis, and the fulminant enlargement of the spleen accompanied by an increased risk of its rupture. Chronic hepatitis B was likely the trigger for transformation of the disease to an aggressive course. Portal vein thrombosis and the aggressive course of SMZL with rapid enlargement of the spleen and threat of its rupture in the background of viral hepatitis B required emergency splenectomy followed by anticoagulant, antiviral, and antitumor therapy.
