Influence of 1,25 dihydroxycholecalciferol on sexual dysfunction and related endocrine parameters in patiens on maintenance hemodialysis.

It has been postulated that hyperparahyroidism is in part responsible for sexual dysfunction in dialyzed patients and that this could improved by 1,25(Oh)2D3. In a single blind study patients on maintenance hemodialysis were treated after a control period with 1,25 (OH)2D3 and with placebo in random order. Sexual performance was assessed with a detailed semistructured psychiatric interview protocol in 14 and several endocrine parameters were analyzed in 15 patients. Under control conditions sexual function was disturbed in 11/14 patients. Plasma testosterone was moderately decreased in men, PRL and PTH levels were distinctly elevated in both sexes. 1,25(OH)2D3 raised serum calcium levels significantly from 9.6 to10.6 mg/100 ml ( P < 0.01) and lowered PTh from 1.39 to 0.82 ng/ml ( P < 0.01). However, no improvement in sexual function (such as libido, frequency of intercourse or masturbation) was found, and apart from a slight rise of testosterone in men and moderate fall of PRl in men and women endocrine parameters remained unchanged. It is concluded that in spite of an improvement of secondary hyperparathyroidism, treatment with 1,25(OH)2D3 for 2 to 4 months was of no value in improving sexual dysfunction in these hemodialysis patients.
