MO803THE UTILITY OF BONE HEALTH INDEX SDS SCORES IN MEASURING BONE DENSITY IN CHILDREN WITH END STAGE KIDNEY DISEASE

Abstract Background and Aims Decreased bone mineral density (BMD) is well recognised in patients on dialysis. Lower DXA-BMD predicts incident fractures with CKD 3a-5D. However while age (BA) Xrays are routinely performed to assess delays density, DXA scans not available widely. We compared the utility of findings using automated measurements routine BA scans. Method In our tertiary paediatric renal unit, replacement therapy reviewed within a joint dialysis/endocrine clinic by an nephrologist endocrinologist,with annual radiological health assessment hand wrist Xray Bone Xpert™ software. This automates BMD Xrays, correcting for calculates index standard deviation score (BHI-SDS) cortical thickness mineralisation metacarpal bones. any patient abnormal or uncontrolled hyperparathyroidism, was (measured as whole body (minus head) lumbar spine (L1–L4)). Z scores were automatically calculated normative data. A review results obtained compare these investigations status dialysis patients. Results 14 ESRD had both BHI-SDS measured. Median chronological 12.6 years at densitometry (range 5.1-16.3 years) median 11.5 4.4-14.8 years). All where evidence osteodystrophy radiographically. -1.2 -3.56 1.5). Z-score -0.5 (range-3.6-2.9) WBMH -2.6-1.5). Pearson correlation coefficients 0.77 0.8 respectively. Only 4/15 (27%) who reported low BMD. one objectively measured loss vertebral height fracture assessment. there two undiagnosed scoliosis anterior wedge shaped identified DXA. These referred orthopaedic management. Conclusion The BHI- SDS measure has been reported. There appears be good between BHI scan therapy. advantages that it less expensive, more easily performed, widely takes into account delay often found children. derived from peripheral skeleton, contrast DXA, which measures total skeleton spine. useful initial quantify changes consistent skeleton. all children should proceed this may detect spinal abnormalities addition.
