[Dynamics of the course of idiopathic juvenile osteoporosis].
Clinical course of the idiopathic juvenile osteoporosis (IJO) was monitored in the group of 45 patients of both sexes with diagnosed disease, verified during follow-up period. The aim of the study was to evaluate the relationship between clinical symptoms and the results of biochemical, anthropometric, and densitometric measurements. An analysis of the obtained data enabled to distinguish the acute and chronic IJO phases. Evolution of the acute phase into chronic one was manifested by the cessation of pain and pathological gait stereotype, normalization of muscular strength, anthropometric parameters and urinary Pyr and DPyr excretion, as well as improvement in bone density. Hypercalciuria and increased urinary excretion of Pyr and DPyr, observed in the acute phase of IJO, may indicate that bone resorption exceeded bone formation. Tendency to maintain of alkaline phosphatase activity within lower limits of the normal values with slight increase during an improvement of densitometric parameters suggested transient osteoblast dysfunction.
