[Hormone content of the blood in juvenile osteoporosis]

Juvenile osteoporosis should be regarded as a polyetiological disease developing against the background of constitutional osteopathy in which endocrine disorders play a certain role. A tendency to a decrease in the levels of calcitonin and parathyroid hormone was found in juvenile osteoporosis; mild signs of hypogonadism (secondary) and a relative decrease in hypophyseal somatotropic activity promoted its detection. Two groups of patients were defined: I--with raised AP activity and a normal or lowered level of serum inorganic phosphorus without hormonal disorders; II--with lowered or normal AP activity and a normal level of phosphorus, mild hormonal disorders. Prolonged multimodality therapy with calcitonin, anabolic steroids, active forms of Vitamin D3, calcium agents, physiotherapy and exercise therapy was found effective in juvenile osteoporosis.
