The impact of sex hormone changes on bone mineral deficit in chronic renal failure.

In chronic renal failure several factors affect bone homeostasis leading to the development of renal osteodystrophy. Common calcitropic hormone derangements in renal failure play a central role in bone structure and mineral defects, which in turn accompany osteodystrophy frequently resulting in low bone mineral density (BMD) values. However, patients with end-stage renal disease (ESRD) suffer from several comorbidities, which may partly account for renal bone disease lesions.

The effect of sexual hormone abnormalities on proximal femur bone mineral density in hemodialysis patients and the possible role of RANKL.

Sexual hormone concentrations are commonly affected in chronic renal failure. The contribution of sex steroids to bone turnover regulation implies that sex steroid's dysfunction may be implicated in the emergence of renal osteodystrophy. This study was conducted to evaluate sex steroids and gonadotrophins in hemodialysis (HD) patients and to investigate their role in bone homeostasis in concert with other hormones and cytokines.

Associations between osteoprotegerin and femoral neck BMD in hemodialysis patients.

Numerous humoral factors are involved in the development of renal osteodystrophy, causing perturbations in bone mineral density (BMD) in patients with end-stage renal disease (ESRD). The RANKL/OPG cytokine system appears to mediate the effects of many of these factors on bone turnover, contributing to the pathogenesis of renal bone disease. The aim of this study was to evaluate the clinical and biochemical correlations of BMD measurements in patients on chronic hemodialysis.
