title: [The effect of glucocorticoids on mineral metabolism in bronchial asthma patients].
abstract: Nuclear-absorption spectrophotometry (AAC-508, Hitachi, Japan) and selective ionometry (microlyte, Kone, Finland) were employed to measure magnesium and calcium concentrations in the serum, red cells, lymphocytes, 24-h urine and exhaled air moisture in 40 patients with hormone-dependent asthma (BA) and 15 BA patients given beclomet, becotid in inhalations and injections of hydrocortisone, prednisolone and dexason. Intravenous infusions and steroid inhalations in moderate doses for 10-14 days induce only insignificant changes in bivalent cation homeostasis. Complications associated with deranged mineral metabolism occurred more frequently in BA patients on long-term (at least 4 years) courses of oral glucocorticoids. Increased renal and bronchial excretion of magnesium and calcium in patients with hormone-dependent BA with complications of glucocorticoid therapy shows its significant contribution to development of steroid osteopathy and myopathy.
