Abstract
Objectives: To determine the prevalence of celiac disease (CeD) in children with short stature (SS) and growth hormone deficiency (GHD).
Methods: This is a retrospective study of patients with isolated SS and GHD, diagnosed during the period 2002 to 2016. Their medical records were reviewed and serum tissue transglutaminase (tTG) antibody results retrieved. Patients with positive serology results underwent upper gastrointestinal endoscopy and small bowel biopsy to confirm the diagnosis of CeD. Clinical, anthropometric, and laboratory data were recorded for all patients.
Results: Of the 351 patients identified with GHD, 199 (56.7%) were male. The mean age +/- SD was 9.0 +/- 3.7 years (range: 2-17.6 years), and the mean +/- SD height-for-age z score was -2.9 +/- 1.3. Partial GHD constituted 42.2% and severe GHD constituted 57.8% of GHD diagnoses. The mean growth hormone (GH) peak level was 5.8 +/- 3.9 ng/ml. Forty-seven patients (13.4%) had positive serology, and 14 (4%) had biopsy-proven CeD. No predictors could be identified through binary logistic regression analysis.
Conclusion: A prevalence of CeD seropositivity was found in 13.4% and overt CeD in 4% of children with GHD. The finding of GHD should not preclude the search for CeD, because the majority will potentially improve on a gluten-free diet (GFD).
