Helicobacter Pylori Eradication Therapy

Evidence relating to the efficacy of Helicobacter pylori eradication therapy for chronic immune thrombocytopenic purpura (cITP) in childhood is inadequate. The aim of this retrospective study was to determine the efficacy of H. pylori eradication therapy for platelet response in pediatric patients with cITP in our hospital, and to perform a systematic review of previous reports about pediatric patients with cITP who were positive for H. pylori infection and were treated with H. pylori eradication therapy. Analysis of the data of pediatric patients with cITP in our hospital and a systematic review of digital literature databases of studies in pediatric patients with cITP were performed. Data of 33 pediatric patients with cITP from our hospital records showed that the prevalence of H. pylori infection and the rate of response to platelet therapy were 15% and 33.3%, respectively. Data of 706 pediatric patients from 18 previous reports showed that the prevalence of H. pylori infection and rate of platelet response were 23% and 43.8%, respectively. Eradication therapy for H. pylori infection in pediatric cITP patients can be expected to result in a response equivalent to that in the adult population, with fewer adverse effects than other treatments for cITP.

AbstractA 34-year-old male with a long history of immune thrombocytopenic purpura (ITP) presents to your office. His platelet count is 30 × 109/L and he is clinically stable with no bleeding symptoms. He has read that Helicobacter pylori eradication therapy may be effective for ITP and he asks you about this. You do not have access to reliable tests for H pylori infection (e.g., urea breath test), yet you wonder about the benefit of empiric eradication therapy for your patient.

AbstractEradication of Helicobacter pylori may lead to improvement of chronic immune thrombocytopenic purpura (ITP), although its efficacy over time is uncertain. We report the results of H pylori screening and eradication in 75 consecutive adult patients with ITP. We also used molecular methods to investigate lymphocyte clonality and H pylori genotypes in the gastric biopsies from 10 H pylori–positive patients with ITP and 19 H pylori–positive patients without ITP with chronic gastritis. Active H pylori infection was documented in 38 (51%) patients and successfully eradicated in 34 (89%) patients. After a median follow-up of 60 months, a persistent platelet response in 23 (68%) of patients with eradicated infection was observed; 1 relapse occurred. No differences in mucosal B- or T-cell clonalities were observed between patients with ITP and control participants. Of note, the frequency of the H pylori cagA gene (P = .02) and the frequency of concomitant H pylori cagA, vacAs1, and iceA genes (triple-positive strains; P = .015) resulted statistically higher in patients with ITP than in control participants. All asymptomatic H pylori–positive patients with ITP were suffering from chronic gastritis. Our data suggest a sustained platelet recovery in a proportion of patients with ITP by H pylori eradication alone. Overrepresentation of specific H pylori genotypes in ITP suggests a possible role for bacterium-related factors in the disease pathogenesis.

Purpose: The aim of this study was to evaluate the presence of H. pylori antigens in the oral cavity (dental plaque and saliva) of patients undergoing systemic eradication therapy. Materials and methods: The study was conducted in 49 subjects with H. pylori stomach infection. H. pylori antigens in dental plaque and saliva were evaluated with immunological method. Results: In subjects with initial H. pylori oral infection, the presence of H. pylori antigens in the oral cavity 6 weeks after successful or unsuccessful H. pylori eradication therapy in the stomach was 47.0% and 50.0%, respectively. In subjects without initial oral infection with H. pylori, the presence of H. pylori antigens in the oral cavity 6 weeks after successful and unsuccessful eradication therapy in the stomach was 30.0% and 20.0%, respectively. Conclusions: The immunological method detecting H. pylori antigens in the dental plaque and saliva cannot be recommended to evaluate the efficacy of H. pylori eradication in the oral cavity.
