Low serum testosterone, arterial stiffness and mortality in male haemodialysis patients.

Background: In the general population, accumulating data support a link between low testosterone levels and mortality by all causes, but especially by cardiovascular disease (CVD). Also, accelerated arterial stiffness has been recognized as an important cardiovascular risk factor. Here, we explored the association between testosterone levels and risk of death in male haemodialysis (HD) patients, whose arterial system is characterized by generalized stiffening.

Magnesium carbonate for phosphate control in patients on hemodialysis. A randomized controlled trial.

Background: Magnesium salts bind dietary phosphorus, but their use in renal patients is limited due to their potential for causing side effects. The aim of this study was to evaluate the efficacy and safety of magnesium carbonate (MgCO(3)) as a phosphate-binder in hemodialysis patients.

Methods: Forty-six stable hemodialysis patients were randomly allocated to receive either MgCO(3) (n=25) or calcium carbonate (CaCO(3)), (n=21) for 6 months.

Prostate-specific antigen in hemodialysis patients and the influence of dialysis in its levels.

The determination of prostate-specific antigen (PSA) is a useful tool in the diagnosis and follow-up of prostate cancer in males, but its diagnostic validity is uncertain in hemodialysis patients. We prospectively evaluated PSA in male hemodialysis patients as well as the influence of a single dialytic session on its levels. We measured pre- and postdialysis total PSA (tPSA) in 63 hemodialysis patients (mean age 68.
