The present study was accomplished in order to determine the gastrointestinal manifestations of CGD patients. Fifty-seven patients (38 males and 19 females) with CGD, who had been referred to three immunodeficiency referral centers in Iran, were studied during a 24-year period (1980-2004). The median age at the time of study was 14.5 years old (1-56 years). The median onset age of symptoms was 5 months (1 month – 13.75 years), and that of diagnostic age was 5 years (2 months- 54.1 years), with a diagnostic delay of 33 months, on average. Seven patients were presented with acute diarrhea, 3 with oral candidiasis, and 2 with liver abscesses as the first chief complaints. Twenty-four cases (42.1%) had been complicated by gastrointestinal manifestations during their course of the disease. Of those, 12 cases (21.1%) had diarrhea, 7 (12.3%) oral candidiasis, 5 (8.8%) hepatitis, 4 (7.0%) hepatic abscess, and 2 cases (3.5%) gastric outlet obstruction. Also, failure to thrive was detected in 6 patients (10.5%). Four patients died (7%). CGD should be excluded in any patient with gastrointestinal manifestations especially chronic diarrhea, hepatic abscess, and gastric outlet obstruction. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/73 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/73/73
