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)

Study Arms (1)
SCD Bone Pain Study Cohort
OTHERProspective 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
Interventions
Measure bone mineral density at the lumbar spine, left total hip, left forearm, and whole body
Obtain thoracolumbar morphometry in DXA scan, then determine presence and severity of vertebral compression fractures by VFA
Calculate patient-reported total pain scores to determine the pain phenotype of each study participant

- Age 18-80 years with SCD (any genotype, confirmed by hemoglobin electrophoresis or high performance liquid chromatography)
- Ability to provide written informed consent
- Ability to lay on a DXA scanner
- Negative urine pregnancy test for women of childbearing potential at study entry
You may not qualify if:
- Pregnant women
- Adults unable to consent
- Individuals who are not yet adults (infants, children, teenagers)
- Prisoners
- Hospitalizations (any cause) within 2 weeks of study entry

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.
