Osteoporosis and Impaired Trabecular Bone Score in Hemodialysis Patients.

BACKGROUND/AIMS: Small attention is paid to other types of bone diseases then chronic kidney disease-mineral and bone disorder in dialysis patients. The aim of our study was to assess the occurrence of osteoporosis and bone microarchitecture by trabecular bone score in this population.

METHODS

59 patients (67.6 ± 13.1 years, 43 males) treated with hemodiafIltration underwent densitometry (Lunar Prodigy, TBS software 2.1.2) and laboratory assessment.

RESULTS

Osteoporosis was observed in 34% patients, high bone turnover was found in 80% of them, with SHPT (PTH > 300 ng/l) present in 69%. TBS was significantly decreased in 47.5% of the patients. TBS correlated with T- and Z-scores of the lumbar spine and proximal femur in the total population (P < 0.0001) and in men (P < 0.00001) and there were significant differences between TBS in groups with normal densitometry, osteopenia, and osteoporosis, both in total population (P < 0.0001; P < 0.01) and in men (P < 0.001; P < 0.001).

CONCLUSIONS

Osteoporosis was found in about 1/3 of patients treated with hemodiafiltration. Normal TBS was found in only 1/4 of the dialysis population. TBS correlated with densitometric parameters and was significantly different relative to T-scores.
