Abstract:

Objective: To determine the accuracy of anti-tissue transglutaminase IgA (TTG) antibody titer in the diagnosis of celiac disease, taking small intestine histopathology as the gold standard. Study Design: Cross-sectional analytical study. Place and Duration of Study: Department of Paediatrics, Benazir Bhutto Hospital, Rawalpindi, from February to July 2013. Methodology: Sixty patients aged 2 - 13 years, admitted in the Paediatric Department of Benazir Bhutto Hospital, Rawalpindi, having at least 3 features from chronic diarrhea, malnutrition, short stature, anemia, abdominal distension and clubbing, were included. Age, gender, weight and height were recorded. Abdominal distension and clubbing were clinically noted. For hemoglobin, blood complete picture was done. For determination of nutritional status and short stature, standard centile charts were used. TTG titer upper GI endoscopy, duodenal biopsy, and histopathology were done in all cases. Results: There were 60 patients; 32 males, 28 females with mean age of 5.85 ±3.36 years. Frequency of CD was 63.33% in study population. Sensitivity of TTG was 86.84%, with 81.82% specificity, 89.19% positive predictive value, and 78.26% negative predictive value for diagnosing CD. TTG titre more than 50 iu/ml had a 100% positive predictive value. Conclusion: TTG is an excellent screening test for the diagnosis of paediatric CD. TTG value > 50 IU/ml has 100% positive predictive value.
