RESUMO
INTRODUCTION: Celiac disease (CD) is a chronic inflammatory disorder affecting mainly the digestive system and accounts for more than 50% of adult cases presenting to the gastrointestinal clinic with chronic diarrhea. Therefore, in our study, we aimed to determine the prevalence of CD in patients presenting with chronic diarrhea at the gastroenterology outpatient department of Jinnah Hospital, Lahore. METHODS: This cross-sectional study was conducted from December 9, 2021, to June 8, 2022, and included 140 patients aged 18 to 50 years with chronic diarrhea. Exclusion criteria were lack of informed consent and history of abdominal trauma or surgery. Data collected included age, gender, family history of CD, and clinical symptoms. Diagnostic measures involved serum tissue transglutaminase antibody IgA and IgG levels, endoscopy, and duodenal biopsy. Statistical analysis was performed using SPSS version 23 (IBM Corp, Armonk, NY), with a p-value of ≤0.05 considered significant. RESULTS: Among the 140 patients, 80 (57.14%) were males, with a mean age of 21 ± 4.35 years. Common symptoms included weight loss (73.5%), abdominal pain (20.7%), and stunted growth (5.7%). A family history of CD was reported in 14.29% of patients. Endoscopy findings included fissuring of the duodenal mucosa (77.9%), decreased height of duodenal folds (15.7%), and nodularity (6.4%). Histopathological examination revealed Marsh III b (65%), Marsh III c (21.4%), and Marsh III a (9.3%). CD was diagnosed in 23.57% of patients. Significant associations were found between CD and female gender, family history of CD, weight loss, stunted growth, and Marsh III c histopathology. CONCLUSION: CD was diagnosed in 23.57% of patients with chronic diarrhea. It was more prevalent in females and those with a family history of CD. These findings emphasize the need for considering CD in the differential diagnosis of chronic diarrhea to ensure early detection and management.
