FOREARM BONE MASS PREDICT MORTALITY IN CHRONIC HEMODIALYSIS PATIENTS

AIM: The aim of present analysis was to determine the relationship between BMD assessed by T and Z score and mortality risk in hemodialysis (HD) patients. Also we were explore which skeletal sites are the best in predicting mortality rate. METHODS: In the present study we have analyzed the survival of 102 patients that were treated with chronic HD according to the bone mineral density (BMD). RESULTS: Patients who had T score ≤ 2.5 at mid part of forearm, at ultradistal and proximal part of forearm had a higher risk for death than those patients who had T score ≥ -2.5 On the other hand, we didn’t find 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. Next we were interested to explore the relationship between Z score in different skeletal regions and mortality risk. We have founded that patients who had Z score ≤ - 1 at all three parts of forearm had a great mortality risk. Also, Z score obtained at all three parts of forearm was an even better predictor of mortality in comparison to T-score in the same skeletal regions. CONCLUSION: Based at our experience, BMD assessed should be obtained at forearm because this skeletal site is a good predictor of mortality in HD patients. Furthermore, data about bone dnsity should be reported as Z-scores.
