title: Helicobacter pylori infection in type 1 diabetes children and adolescents using 13C urea breath test.
abstract: There is a 10-30% prevalence of HP infection in the general pediatric population in Poland. This study aimed to determine its prevalence in T1DM children in Upper Silesia, Poland and estimate its influence on metabolic control of patients. We studied 149 (82 female) children with T1DM (duration > 12 months, mean HbA1c) and 298 (164 female) age-matched controls. In all cases height and weight z-scores and Cole's index were assessed. In T1DM patients additionally glycated hemoglobin A1c and T1DM duration were analyzed. Presence of HP infection was determined using 13C-isotope-labeled urea breath test (UBT) (fasting and 30 min after ingestion 75 mg of 13C urea). HP infection was present in 17 (11.4%) T1DM patients and in 49 (16.4%) controls (p > 0.05). T1DM patients presented higher values of anthropometric parameters than healthy controls (weight SDS 0.25[-0.46 divided by 0.84] vs. -0.25 [-1.06 divided by 0.26], height SDS 0.09 [-0.60 divided by 0.69] vs. -0.31[-1.17 divided by 0.48] and Cole's index 103% [93 divided by 111%] vs. 97% [86 divided by 106%]; for all p < 0001). Within both groups--T1DM children and controls--no differences regarding sex, age and any of the anthropometric parameters were determined. T1DM duration and HbA1c showed no relation to prevalence of HP infection. Prevalence of HP infection in pediatric T1DM patients is similar to that of healthy peers and shows no relation to glycemic control.
