Aim:
The aim of this study was to assess the prevalence of celiac disease (CD) in dyspeptic patients.
Background:
Although severe mucosal abnormality with villous atrophy (lesions Marsh III) is the histology gold standard for the diagnosis of CD, non-specific microenteropathy (Marsh I-II) with positive serology is also common Patients with dyspepsia, specific CD antibodies and microenteropathy, could have CD.
Patients And Methods:
From November 2007 to October 2008, 407 randomly chosen patients who underwent diagnostic upper gastrointestinal endoscopy for dyspeptic symptoms (193 male, 214 women; mean age 36.1 years) were studied. Small bowel biopsies were performed in all of them. Histologic characteristics in duodenal biopsy specimens for CD were evaluated according to the modified Marsh Classification. All the patients were also tested for serum total immunoglobulin A and anti-transglutaminase (tTG) antibodies. Those with IgA deficiency were tested for IgG tTG.
Results:
Duodenal histology showed Marsh I-IIIc lesions in 6.4% cases. 4 patients (0.98%) were IgA deficient and none of them were positive for IgG tTG. Serology showed positive results for tTGA in 8% of the patients and 2.5% of them had abnormal histology (Marsh I-IIIc) compatible with CD.
Conclusion:
The results of this study showed that milder enteropathy (Marsh 0-II) have a low specificity for CD. The prevalence of CD among dyspeptic individuals is significantly (2.5%) higher than in the general population (1%) and CD should be investigated in these patients.

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
