Comparative Effects of Doxercalciferol and Calcitriol on Secondary Hyperparathyroidism in ESRD

Sponsor: Chittagong Medical College

Summary

Secondary hyperparathyroidism (SHPT) is a common complication of advanced chronic kidney disease (CKD), caused by phosphate retention and vitamin D deficiency, leading to elevated parathyroid hormone (PTH) levels and increased bone and cardiovascular complications. Active vitamin D analogs such as calcitriol and doxercalciferol are used to suppress PTH levels, though they differ in pharmacologic properties and effects on mineral metabolism. Intravenous preparations may offer improved bioavailability and adherence in hemodialysis patients.This randomized controlled trial will be conducted in the Department of Nephrology at Chittagong Medical College Hospital among 98 adult hemodialysis patients with SHPT. Participants will be randomly assigned to receive either intravenous doxercalciferol or oral calcitriol. The study aims to compare their effectiveness in lowering PTH levels and evaluate safety outcomes. Continuous variables will be expressed as mean ± standard deviation, while categorical variables will be presented as frequencies and percentages. Independent t-tests, chi-square tests, or Fisher's exact tests will be used for statistical comparisons. Data analysis will be performed using SPSS version 27.0, with a p-value \<0.05 considered statistically significant.
