FOREARM BONE MASS PREDICT MORTALITY IN CHRONIC HEMODIALYSIS PATIENTS

AIM: The analysis aims to determine relationship between BMD assessed by T and Z score and mortality risk in hemodialysis (HD) patients. Furthermore, it explores which skeletal sites are most suitable for predicting mortality rate. METHODS: Present study has analyzed the survival of 102 patients who had been treated with chronic HD according to the bone mineral density (BMD). RESULT: Patients who had T score ≤ 2.5 at mid part of forearm, at ultradistal and proximal part of forearm, suffered from a higher death risk than those T score was ≥ -2.5. But besides that, there has not been found any statistically significant association between losses of bone mass at other measuring points – lumbar spine (antero-posterior orientation from L1-L4) and hip (neck, trochanter, intertrochanter, total and Ward's triangle) – and mortality risk. Moreover, the examination has been interested in exploring a relationship between Z score in different skeletal regions and mortality risk. It has been found that patients who had Z score ≤ -1 at all three parts of forearm had a great mortality risk. Also, it is worth to mention that Z score noted at all three parts of forearm was more apparent predictor of mortality, compared to T-score in the same skeletal regions. CONCLUSION: This empirical analysis showed that BMD assessed should be obtained at forearm, due to a good predictability quality of this skeletal site, when it comes to mortality of HD patients. What is second, data concerning bone density should be reported as Z-scores.
