Abstract

Background/objectives: Primary antibody deficiencies (PADs) are the most common inherited immunodeficiencies, which can present wide clinical presentation including susceptibility to bacterial infections and gastric adenocarcinoma. Since Helicopter pylori (H. pylori) infection is associated with immune dysregulation and an increased risk of gastric carcinogenesis, we evaluated the prevalence of HP infection in patients with different forms of PAD. Methods: Thirty-seven patients with common variable immunodeficiency (CVID), 23 patients with X-linked agammaglobulinemia (XLA), and eleven patients with hyper IgM syndrome (HIgM, age range 8-25; 47 males and 24 females) were screened for H. pylori infection by Urea breath test (UBT) and H. pylori stool antigen (HPSA). Subsequently, an upper gastrointestinal endoscopy was conducted only for patients who had UBT and HPSA positive results due to an established gastrointestinal indication. Results: Although almost all patients were under prophylactic antibiotic therapy, H. pylori infection was detected in 28% (n=20) of the patients; among different forms of PAD, 29% (n=11) of CVID patients, 30% (n=7) of XLA, and 18% (n=2) of HIgM patients were infected. Among patients with H. pylori infection, the rate of parasite infections was higher, while the prevalence of autoimmunity and autoinflammatory disorders increased in patients without H. pylori infection. Conclusions: Despite regular immunoglobulin replacement therapy and antibiotic prophylaxis, one-fourth of PAD patients had a persistent H. pylori infection though without severe gastrointestinal manifestations. Long-term follow-up of these selected patients is essential to evaluate its association with gastric cancers.
