RESUMEN
Aim The objective of the study was to observe the association of villous atrophy with anti-tissue transglutaminase levels in the identified subjects that met our addressed inclusion criteria. Methods A case series study was conducted among 40 patients presenting with dyspepsia along with signs and symptoms of celiac disease at the Bolan Medical Complex Hospital, Quetta over a period of five months from 25/5/17 to 25/10/17. The patients were referred to undergo tissue transglutaminase antibody serum test. The positive ones underwent biopsies to assess pathological entities including villous atrophy, blunting (focal or total), crypts, Intestinal layers and the number of Intraepithelial lymphocytes. The results collected were analyzed by using IBM SPSS version 20 (IBM Corp., Armonk, NY). Results There was a weak, negative correlation between tTGA and focal villous blunting (r = -0.345, p = 0.029) showing that high levels of tTGA are associated with lower risk of focal villous blunting. Correlation of tTGA and total villous blunting was a weak positive correlation (r = 0.282, p = 0.07) showing that high levels of tTGA are associated with increased risk of total villous blunting. There was a weak, negative correlation between tTGG and focal villous blunting (r = 0.409, p = 0.009) showing thathigh levels of tTGG are associated with a greater risk of focal villous blunting (p < 0.01) while tTGG and total villous blunting was a weak negative correlation (r = -0.330, p = 0.03) showing that high levels of tTGG are associated with lower risk of total villous blunting. Conclusion The study concludes by providing evidence of the absence of tissue transglutaminase antibodies in patients with histology-proven celiac disease. It implies that serology tests may be negative in some of the patients with typical chronic symptoms. Therefore, in such cases, histopathology may be conclusive in defining the status of celiac disease.
