Background And Study Aims:
Unawareness about atypical forms of celiac disease (CD) leads to the underdiagnoses of CD. This study has investigated the prevalence of CD in patients with atypical presentations, such as idiopathic low bone mineral density (ILBMD) and dyspepsia, in the Iranian population.
Patients And Methods:
Two separate groups of patients who have been diagnosed with dyspepsia and ILBMD (including either osteopenia or osteoporosis of unknown cause) were screened for CD during 2016-2019. Patients were serologically screened by means of IgA anti-tissue transglutaminase (IgA anti-tTG); in case of positive results, the patients underwent endoscopic intestinal biopsy to confirm the diagnosis of CD.
Results:
Of 200 patients with ILBMD, six (3%) had a positive result for IgA anti-tTG; in five cases (2.5%), duodenal histology confirmed the CD diagnosis. Of 290 patients with dyspepsia, 25 (8.6%) had a positive result for anti-tTG IgA; nine cases (3.7%) were histologically compatible with CD. No significant differences were found between the two groups of patients.
Conclusions:
The prevalence of CD in patients with atypical presentations, such as ILBMD and dyspepsia, is consistent (pvalue = 0.788) and higher than that in the general population (p value = 0.001); therefore, screening program for CD in these patients is highly recommended.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
