title: Clinical onset of the Crohn's disease after eradication therapy of Helicobacter pylori infection. Does Helicobacter pylori infection interact with natural history of inflammatory bowel diseases?
abstract: BACKGROUND
  There are conflicting reports concerning the prevalence of Helicobacter pylori infection in patients with inflammatory bowel diseases: some studies connected Sulphasalazine therapy and lower incidence of Helicobacter pylori infection, but others showed lower prevalence of Helicobacter pylori infection in inflammatory bowel diseases despite the choice of therapy.
  
  
  METHODS
  A 28-year-old male patient presented in January 1996 with the symptoms of ulcer like dyspepsia. There was no significant abnormality on physical examination, laboratory testing and abdominal ultrasound. Histology examination of the biopsy specimen taken during the upper endoscopy revealed Helicobacter pylori associated active gastritis only in the corporal part of the stomach. After two weeks eradication therapy (Omeprazole, Amoxicillin) he was well. Three months later, at the control endoscopy, granulomatous gastritis of the corporal localization was detected, without Helicobacter pylori present. Antral mucosa appeared normal, both, on endoscopy and histology examination. In July 1996 he started with cramping abdominal pain, mild periodical fever and episodes of watery diarrhea. In laboratory results we found nonspecific signs of inflammation. We repeated upper endoscopy, colonoscopy and enteroclysis--with evidence of segmental stenotic lesions of the upper part of ileum and jejunum. Again, we confirmed granulomatous gastritis and small granuloma in the proximal jejunum. After starting the 5-ASA therapy in combination with Metronidazol, patient was better clinical condition, and laboratory results were normal. We suggested mesalamine maintenance therapy 1 gr. every day, and three years later he is well, in clinical remission of Crohn's disease.
  
  
  CONCLUSIONS
  The clinical course of the Crohn's disease maybe "sui generis" connected with Helicobacter pylori infection- but the exact mechanisms remain to be discovered.
