SCHONLEIN-HENOCH PURPURA ASSOCIATED WITH GASTRIC HELICOBACTER-PYLORI INFECTION

Schonlein-Henoch purpura is characterized by palpable purpura, colicky abdominal pain, gastrointestinal hemorrhage, arthralgias, and renal involvement. Bacterial and viral infections, as well as drugs and diseases associated with immune complexes, are thought to be responsible. We describe the case of a 21-year-old woman with Schonlein-Henoch purpura and chronic active gastritis with erosions. Helicobacter pylori was found in gastric mucosa using the newly introduced, nontoxic, noninvasive C-13-urea breath test; infection was confirmed by gastric mucosal biopsy. After eradication of H. pylori with omeprazole and amoxicillin, the skin changes, gastric complaints, and proteinuria disappeared. Ten months later, Schonlein-Henoch purpura recurred. H. pylori was again detected. After therapy, H. pylori was eradicated and the clinical manifestations faded. To our knowledge, H. pylori has not previously been described as a cause of Schonlein-Henoch purpura.
