Hair magnesium, but not serum magnesium, is associated with left ventricular wall thickness in hemodialysis patients.

Background: Extracellular magnesium (Mg) accounts for approximately 1% of the total body Mg. Clinically, serum Mg concentration is measured, but it does not necessarily reflect total body Mg status. Although relationships have been reported between reduced Mg and cardiovascular disease in non-dialysis patients, there have been few such studies in hemodialysis patients.

Serum n-3 and n-6 polyunsaturated fatty acid profile as an independent predictor of cardiovascular events in hemodialysis patients.

Background: Unlike the n-6 polyunsaturated fatty acid (PUFA) arachidonic acid (AA), n-3-PUFAs such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) appear to have beneficial effects on inflammation, thrombosis, and cardiovascular disease (CVD). We examined possible alterations in serum PUFA profiles in patients on maintenance hemodialysis therapy and its association with CVD risk.

Study Design: An observational study including cross-sectional and longitudinal analyses.

Decreased serum adrenal androgen dehydroepiandrosterone sulfate and mortality in hemodialysis patients.

Background: Endocrine and metabolic abnormalities may affect the survival of hemodialysis patients. Serum dehydroepiandrosterone sulfate (DHEA-S), an adrenal androgen with anabolic properties, is known to be lowered in ill patients and predicts poor outcome in the general population and in those with cardiac disease. The aims of this study were to examine a possible change in the DHEA-S level in dialysis patients and its association with survival in this population.

Trace elements in the hair of hemodialysis patients.

Trace element disturbance is often observed in hemodialysis patients. While trace element concentrations have been reported in blood samples from hemodialysis patients, they have not been well investigated in scalp hair. In the present study, 22 trace elemental concentrations were measured by inductively coupled plasma-atomic emission spectrometry in the scalp hair of 80 male hemodialysis patients and compared with those of 100 healthy male subjects.
