Outcome Measures

Primary Outcomes (7)

  • Lumbar Spine Bone Mineral Density

    Areal bone mineral density of the lumbar spine measured by dual-energy X-ray absorptiometry (DXA) scan and reported in grams per square centimeter.

    Baseline

  • Lumbar Spine Bone Mineral Density-Z-scores

    Number of standard deviations between measured lumbar spine bone mineral density (g/cm2) for each participant and mean lumbar spine bone mineral density (g/cm2) of the reference population. A Z-score of 0 represents the mean of the reference population. A negative Z-score means the measured bone mineral density values are lower (worse) the reference mean, while positive Z-scores mean they are above/higher. Bone mineral density Z-scores ≤ -2 indicates low bone density.

    Baseline

  • Total Hip Bone Mineral Density (BMD)

    Areal bone mineral density of the total hip measured by dual-energy X-ray absorptiometry (DXA) scan and reported in grams per square centimeter.

    Baseline

  • Total Hip Bone Mineral Density-Z-scores

    Number of standard deviations between measured total hip bone mineral density (g/cm2) for each participant and mean total hip bone mineral density (g/cm2) of the reference population. A Z-score of 0 represents the mean of the reference population. A negative Z-score means the measured bone mineral density values are lower (worse) the reference mean, while positive Z-scores mean they are above/higher. Bone mineral density Z-scores ≤ -2 indicates low bone density.

    At enrollment

  • Femoral Neck Bone Mineral Density (BMD)

    Areal bone mineral density of the femoral neck measured by dual-energy X-ray absorptiometry (DXA) scan and reported in grams per square centimeter.

    Baseline

  • Femoral Neck Bone Mineral Density Z-scores

    Number of standard deviations between measured lumbar spine bone mineral density (g/cm2) for each participant and mean lumbar spine bone mineral density (g/cm2) of the reference population. A Z-score of 0 represents the mean of the reference population. A negative Z-score means the measured bone mineral density values are lower (worse) the reference mean, while positive Z-scores mean they are above/higher. Bone mineral density Z-scores ≤ -2 indicates low bone density.

    Baseline

  • Adult Sickle Cell Quality of Life Measurement System (ASCQ-Me) Pain Impact T-scores

    Patient-reported outcome measure of pain impact in the preceding 7 days before bone density measurements. The Adult Sickle Cell Quality of Life Measurement System (ASCQ-Me) pain impact T-scores range from about 30-100. The ASCQ-Me pain impact T-score has standardized mean T-score of 50 and standard deviation of 10, which were derived from a reference population of ambulatory adult with sickle cell disease across the United States. ASCQ-Me pain impact T-scores less than 50 are lower/worse than the reference mean (more severe pain impact), while pain impact T-scores greater than 50 are above/better than the reference mean (less severe pain impact)

SCD Bone Pain Study Cohort

OTHER

Prospective cohort of 50 adults with sickle cell disease (SCD) undergoing research DXA scan to assess bone mineral density and thoracolumbar morphometry for vertebral fracture analysis

Other: Dual-energy X-ray absorptiometryOther: Vertebral fracture analysisOther: Adult Sickle Cell Quality of Life Measurement System pain impact questionnaire

Interventions

Measure bone mineral density at the lumbar spine, left total hip, left forearm, and whole body

Also known as: DXA scan
SCD Bone Pain Study Cohort

Obtain thoracolumbar morphometry in DXA scan, then determine presence and severity of vertebral compression fractures by VFA

Also known as: VFA
SCD Bone Pain Study Cohort

Calculate patient-reported total pain scores to determine the pain phenotype of each study participant

Also known as: ASCQ-Me Pain scores
SCD Bone Pain Study Cohort

Limitations and Caveats

This prospective study on the association between bone density and pain in SCD is limited by its cross-sectional study design and small sample size. We can only report associations between the predictor variables and outcomes of interest, not causality. Since joint imaging was only done based on symptoms, we may have missed participants with asymptomatic osteonecrosis. Lastly, DXA scans are widely used to clinically assess severe low BMD but cannot differentiate trabecular vs cortical bone loss.
