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).

About this study

Official title: Association of Vitamin D Deficiency, Sarcopenia, Body Composition, Osteoporosis and Hemophilic Arthropathy in the Patients With Hemophilia

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.

Read the detailed 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Vitamin D

    serum vitamin D

    Measured: one day

Secondary outcomes (5)
  1. Bone marrow density

    Bone marrow density of lumbar spine and bilateral hip by dual X-ray absorptiometry (DXA)

    Measured: one day

  2. Body composition

    using whole-body DXA (GE Lunar iDXA, GE Healthcare Lunar, Madison, Wisconsin, U.S.A.)

    Measured: one day

  3. Pettersson score

    Bilateral shoulder, elbow, hip, knee, ankle joints score by x-ray. The Pettersson score ranges from 0 (normal) to 13 (most severe) and is according to the following eight radiographic features of joints: osteoporosis, osteophytes, narrowing of joint space, subchondral irregularity, subchondral cyst formation, erosion of joint margins, and bone remodelling.

    Measured: one day

  4. Hemophilia Joint Health Score

    Functional and structured score of bilateral elbow, knee and ankle. The score for each joint is the sum of several elements including swelling (0-3), duration of swelling (0-1), muscle atrophy (0-2), crepitus of motion (0-2), flexion loss and extension loss (0-6), joint pain (0-2) and strength (0-4). A score of 20 may indicate the most severe damage/impairment in the evaluated joint and a score of zero corresponds to no identifiable joint impairment.

    Measured: one day

  5. Handgrip strength

    Handgrip strength (kg) will be measured using the same standard calibrated hand dynamometers (Baseline® Hand Dynamometer - Digital LCD Gauge, Fabrication Enterprises Inc. White plains, New York, USA). We will calculate the mean of three maximal grip-strength measurement in each hand.

    Measured: one day

Questions about this trial

What is this clinical trial studying?

An observational study of Vitamin D Deficiency and Sarcopenia, run by Tsung-Ying Li at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Vitamin D (time frame: one day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Aug 2024.
