Gastroduodenal inflammation in patients with nonulcer dyspepsia

Abstract

Proper control and quantitation are important in the accurate evaluation of gastroduodenal inflammation in dyspeptic patients without ulcers or erosions as proved by endoscopy. The endoscopic findings and the gastroduodenal mucosal inflammatory cell count in 31 patients with nonulcer dyspepsia were compared with an age-matched group of 32 healthy controls. Endoscopy revealed similar mucosal changes and in similar frequency in both groups. Differential mucosal inflammatory cell count showed a statistically significant (PP<0.05) increase in the round cell and eosinophil count of the duodenal mucosa alone. No correlation was found between the endoscopic changes and an increase in neutrophil count above a normal level determined by the healthy controls. However, an endoscopically normal mucosa was more likely to be associated with a normal neutrophil count. Active inflammation of the gastroduodenal mucosa likely accounts for the symptoms in patients with nonulcer dyspepsia.
