Original description
This study aims to evaluate the effect of long-term use of Tenofovir Disoproxil Fumarate (TDF) on bone density in patients with chronic hepatitis B virus (HBV) infection. Tenofovir is a widely used antiviral medication for the treatment of HBV. While it is generally well tolerated, some studies have reported potential adverse effects on bone mineral density, particularly with long-term use.Read full original descriptionShow less

Effect of Long-Term Use of Tenofovir (TDF) on Bone Density in Patients With Chronic Hepatitis B

This study aims to evaluate the effect of long-term use of Tenofovir Disoproxil Fumarate (TDF) on bone density in patients with chronic hepatitis B virus (HBV) infection. Tenofovir is a widely used antiviral medication for the treatment of HBV. While it is generally well tolerated, some studies have reported potential adverse effects on bone mineral density, particularly with long-term use.

The objective of this research is to assess whether extended TDF therapy is associated with reduced bone density or increased risk of osteopenia or osteoporosis in adult patients with chronic HBV infection. The study will involve clinical evaluation and radiological assessment of bone health using dual-energy X-ray absorptiometry (DEXA) scans, as well as relevant biochemical markers.

This investigation will provide important data on the long-term safety profile of Tenofovir in relation to bone health and help guide future clinical decisions for the management of chronic hepatitis B.

Inclusion: -; Adult male or female patients aged 18 to 60 years; Diagnosed as HBV-positive; Long-term use of Tenofovir Disoproxil Fumarate (TDF) for more than five years.

Exclusion: Patients on combination therapy, including:; Interferon and Nucleoside analogue combination therapy; Multiple nucleoside analogue combination therapy; Presence of other chronic liver diseases; Diagnosed with Chronic Kidney Disease (CKD), regardless of etiology; Patients who refuse to participate in the study; -.
