BACKGROUND: In Osteogenesis Imperfecta severity of disease and reduced physical activity have been considered the main factors contributing to hypercalciuria; however, its pathogenesis in Osteogenesis Imperfecta Type I, in which mobility is normal, is still unclear.
PATIENT, METHODS AND RESULTS: We describe a patient with Osteogenesis Imperfecta Type I and hypercalciuria, in whom measurement of calcium intake, plasma 1 - 25(OH) (2) Vitamin D, fasting calciuria and tubular proteinuria led us to exclude an absorptive or renal component in the pathogenesis of hypercalciuria.
CONCLUSIONS: We believe that hypercalciuria is determined by bone disease in Osteogenesis Imperfecta Type I. This condition should be added to the causes of normocalcemic hypercalciuria in children and the mildest forms should be differentiated from Idiopathic Hypercalciuria.
