The Effects of Vitamin D and Calcium Supplementation to Parathyroid Hormone in CHB Patients Treated With Tenofovir Disoproxil Fumarate

Mahidol University·interventional·Posted Apr 6, 2022·Updated Sep 5, 2024

In Brief

A Phase 4 clinical trial evaluating Ergocalciferol Capsules and Calcium carbonate for Parathyroid Hormone and 3 related conditions. Completed, enrolled 64 participants across 1 site.

Detailed Summary

Nucleot(s)ide is an antiviral drug that can reduce the number of viruses, reduce the risk of HCC, regress hepatic fibrosis and reduce death from Hepatitis B viral infection. Tenofovir disoproxil fumarate (TDF) is one of nucleotide analogue that is recommended to treated patients with Hepatitis B viral infection. However, long-term TDF therapy may have side effects especially nephrotoxicity and bone toxicity. Previous studies in human immunodeficiency virus (HIV) infected patients who treated with TDF containing regimen antiretroviral therapy, in vitamin D supplement group had a statistic significance of low parathyroid hormone level and better in bone mineral density regardless of initial vitamin D level. Therefore, the main objective of this study is to evaluate the vitamin D and calcium supplement to patients with hepatitis B who have taken TDF, in parathyroid hormone level, bone mineral density, renal function and renal phosphate loss compared to patients who have no vitamin D and calcium supplement.
