BACKGROUND & AIMS
Nonsteroidal anti-inflammatory drug (NSAID) gastropathy is sufficiently important as to warrant co-administration of misoprostol or proton pump inhibitors or a switch to selective… (More)

BACKGROUND & AIMS
Conventional acidic nonsteroidal anti-inflammatory drugs frequently cause small bowel inflammation. Diagnosis is largely based on assay of surrogate markers of inflammation in… (More)

BACKGROUND & AIMS
It has been variably suggested that nonselective NSAIDs and cyclooxygenase (COX)-2 selective inhibitors aggravate or ameliorate clinical disease activity in patients with… (More)

BACKGROUND AND AIMS
Assessing the presence and degree of intestinal inflammation objectively, simply, and reliably is a significant problem in gastroenterology. We assessed faecal excretion of… (More)

BACKGROUND
Prolonged gastric acid suppression leads to hypergastrinaemia, which promotes hyperplasia of the enterochromaffin-like (ECL) cells of the oxyntic mucosa. The objective was to determine the… (More)

BACKGROUND
Selective inhibitors of cyclooxygenase (COX)-2 may provoke less gastric damage and platelet inhibition than conventional non-steroidal anti-inflammatory drugs.
