Course of inflammatory bowel disease in patients infected with human immunodeficiency virus.

Background: Human immunodeficiency virus (HIV) infection depletes CD4+ lymphocytes, which may benefit patients with inflammatory bowel disease (IBD). The aim was to compare the course of IBD in HIV patients with a matched group of IBD seronegative patients.

Methods: A total of 20 IBD (14 Crohn's disease, 6 ulcerative colitis) HIV infected patients and 40 matched control seronegative IBD patients (2 controls per case) were compared regarding relapse of their disease.

Prevalence and axial length of hiatus hernia in patients, with nonerosive reflux disease: a prospective study.

Background And Aims: The relationship between hiatus hernia and reflux esophagitis is well established. However, there are conflicting reports regarding its effect on the development of nonerosive reflux disease (NERD). Our aim was to investigate the prevalence and axial length of hiatus hernia in patients with NERD, compared with patients with reflux esophagitis, Barrett esophagus, and controls.
