This study investigated the effect of screening detected celiac disease in type I diabetic children in a multi-center case-control fashion. The research team consisted of B Rami, Z Sumni, E Schober et al from Austria, Czech Republic, and Slovenia, among other European countries. The team compared 98 diabetics with silent celiac disease to 196 control diabetics without celiac matched for age, sex, diabetes duration. Mean age at diabetes diagnosis was 6.5 yrs, celiac diagnosis was 10.0 yrs. HbA1c, hypoglycemia, ketoacidosis, insulin dosage, body-mass index, and height did not differ between cases and controls. After diagnosis of celiac disease, weight gain was diminished in boys with celiac disease compared to their controls.
