Vitamin D Deficiency & Body Composition in the Patients With Hemophilia

Status Recruiting

Clinical Trial Summary

Hemophilia is associated with osteoporosis and increased prevalence of low bone mineral density (BMD). Many clinical risk factors have been reported, such as hemophilic arthropathy, reduced physical activity, decreased sun exposure, hepatitis C virus infections, vitamin D deficiency, and low body mass index (BMI). There is no data on the prevalence of vitamin D deficiency and low BMD in hemophilia patients in Taiwan or Asia. To the best of our knowledge, no previous studies have reported the prevalence of sarcopenia and correlation with osteoporosis in hemophilia adult patients. The purpose of this study will evaluate the prevalence of vitamin D deficiency, low BMD, sarcopenia and body composition in a cohort of patients with hemophilia in Taiwan.

Clinical Trial Description

Hemophilia is associated with osteoporosis and increased prevalence of low bone mineral density (BMD). Soucek et al. reported sarcopenia and low trabecular BMD at the radius in the boys with hemophilia by CT.The severity of hemophilic arthropathy associated with lower BMD, muscle atrophy and obesity has been shown by some studies. This is a single-center, cross-sectional, observational study. All participants will sign informed consent that fully disclosed the risks and benefits of study participation. The study will be performed at the Hemophilia Care and Research Center. Sixty adult patients (age ≥ 20) with hemophilia and 20 healthy subjects will be enrolled for scanning of the lean tissue, appendicular skeletal muscle mass (ASM), fat mass, lumbar spine and hip BMD by dual-energy X-ray absorptiometry (DXA) and assess serum vitamin D level. We will collect other clinically relevant information, including age, body mass index (BMI), hemophilia type and severity, inhibitor titer, Pettersson score by x-ray, HJHS, handgrip strength, history of HCV or HIV infection and history of fracture. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
