Abstract

Osteoporosis is a complication of adult celiac disease. The gluten-free diet improves but does not normalize bone mineral density. Only few and conflicting data are known about the influence of the disease and diet on bone mineralization in children. The aim of this study was to evaluate the radial bone mineral content (BMC) and density (BMD) in children and adolescents who are asymptomatic on gluten-free diet. The BMD and BMC values of non-dominant radius midshaft in ninety-one children (53 girls and 38 boys, mean age: 11.7 years, mean duration of disease: 8.7 years) were determined by single photon absorptiometry. At the diagnosis and at least three years after gluten-free diet, serum calcium, phosphorous and albumin concentrations and alkaline phosphatase activities were determined in all, and additionally intact parathormone concentrations in 16 patients. The mean BMC Z-score value in the entire study population did not differ from the value of normal age-matched population (mean Z-score: -0.27), but in female adolescent group was significantly lower than the normal value (mean Z-score: -1.04, p < 0.01). In contrast, the mean BMC Z-score value was significantly higher than in normal value in girls (mean Z-score: +1.36, p < 0.001), in boys (mean Z-score: +0.53, p < 0.02) as well as in the total patients group (mean Z-score: +1.01, p < 0.001). The diameter of radius midshaft was significantly smaller in all age group than the normal mean value. Serum laboratory parameters of asymptomatic patients were in the normal range. The serum parathormone value in treated patients was significantly lower than in untreated celiac children (mean +/- SD: 3.77 +/- 1.07 versus 7.89 +/- 2.54, p < 0.01), but significantly higher compared to controls (2.89 +/- 0.9, p < 0.05). The data indicate that the gluten-free diet alone is not able to normalize bone mineralization in children. The significant increase of serum parathormone level in treated asymptomatic patients may be explained by the lower calcium content of gluten-free diet. The authors suppose that low calcium supply in children similarly to adult patients can lead to increased parathormone secretion, which can cause the retardation of bone growth even in treated patients with celiac disease.
