[Oral calcitriol pulse therapy in treatment of secondary hyperparathyroidism in patients with long term hemodialysis].

Abstract
Oral calcitriol pulse therapy slowly becomes a method of choice in the treatment of secondary hyperparathyroidism in hemodialysis patients. It appears to be equally effective and simultaneously significantly cheaper than an intravenous therapy. In last year we have applied such a treatment to 12 hemodialysis patients with severe secondary hyperparathyroidism (iPTH range: 447-1228 pg/ml). All of them were hemodialysed 3 times a week with dialysate Ca+2 level 1.25-1.75 mM/l. Calcium carbonate was administered to maintain serum Ca level between 9.0-11.0 mg/dl and phosphate below 6.0 mg/dl. The patients were given calcitriol at dose 0.1 microgram/kg once a week, but it was obligatory to take a drug at bedtime, at least two hours after the last meal, a day before hemodialysis. During the treatment we divided the patients into two groups: I-patients who responded to our treatment (7/12); II-treatment was unsuccessful (5/12). In this group we decided to increase the dose of calcitriol to 0.075 micrograms/kg twice a week after 6 months use of a previous one. We have achieved statistically significant decrease of parathormone (p < 0.001) and alkaline phosphatase (p < 0.02) in group I and after the increase the dose of calcitriol there occurred the decrease of parathormone (p < 0.05) and alkaline phosphatase (p < 0.002) in group II. Simultaneously we have observed a great clinical improvement. Our results confirm the fact that even severe secondary hyperparathyroidism can be successfully treated with oral calcitriol pulse therapy. Administering of high doses of calcitriol at bedtime increases safety of this procedure-we have not observed any case of hypercalcemia.
