Testosterone concentrations andoutcomes in hemodialysis patients of the EVOLVE trial

• BACKGROUND: Hypogonadism is common in end-stage kidney disease and may contribute to morbidity and mortality.METHODS: Using data from the randomized controlled EVOLVE trial of cinacalcet, we analyzed the associations of total testosterone, free testosterone, and sex-hormone binding globulin (SHBG) serum concentrations with mortality and major cardiovascular events in 1692 men and 1059 women receiving hemodialysis. We also describe the effect of cinacalcet treatment on serum concentrations of testosterone.RESULTS: Among men, lower serum free testosterone (OR 0.18 95%, CI 0.04-0.82, p = 0.026) and higher SHBG (OR 1.05 per 10 nmol/L, 95% CI 1.01-1.10, p = 0.012), but not total testosterone, were associated with higher risk of death or cardiovascular event. Only SHBG was associated with all-cause mortality (OR 1.07 per 10 nmol/L, 95% CI 1.02-1.12, p = 0.0073). Among women, neither total- or free testosterone, nor SHBG were associated with outcomes. We found no statistically significant effect of cinacalcet treatment on SHBG, free- or total testosterone.CONCLUSIONS: Lower free testosterone and higher SHBG in serum are associated with higher risk of death or cardiovascular event in men undergoing chronic hemodialysis.
