“…Indeed, considering a lower limit of normal of 45 μg/L, 45.9% of the HD patients had a serum Se level below this level. In this context, it is worth mentioning that an association between serum Se levels below 45 μg/L and an increased risk of cardiovascular disease and cancer has been reported [17][18][19]. Interestingly, a positive correlation was found between serum Se and albumin levels in the HD population.…”

Whole blood and serum samples of Chinese stable chronic renal failure (CRF) patients (n = 81), hemodialysis patients (n = 135), posttransplant patients (n = 60), and subjects with normal renal function (NRF; N = 42) were collected, as well as water and dialysate samples from five dialysis centers. The concentration of selenium (Se), lead (Pb), and cadmium (Cd) was measured by atomic absorption spectrometry. The mean serum Se levels in patients with different degrees of renal failure were significantly lower than those of subjects with NRF (p < 0.01). Pb levels were not increased in renal failure patients, while the Cd levels in patients with various degrees of renal failure were higher than in subjects with NRF (p < 0.05). After correcting the results of Pb and Cd for hematocrit (Hct) however, Pb levels of dialysis patients were also increased. In the dialysis population under study, blood Pb and Cd levels were closely related to the time on dialysis, while contamination of the final dialysate may also contribute to the increased blood Cd and to a less extent Pb levels. Correction for Hct may be recommended to accurately compare blood Pb and Cd levels in dialysis patients and CRF patients with varying degrees of anemia to those of subjects with NRF.

“…This could be due to the low levels or low bioavailability of Se in the soil. In fact, the Canary population has a low Se status45 and therefore it might be of interest to apply an intervention program to increase Se levels of the soils of certain crops such as onions.…”

“…The solutions were then diluted to 25 mL with deionized water and submitted to selenium reading. [14][15][16][17][18] The method used in the reading was hydride generation atomic absorption spectrometry coupled to the quartz cell (HGQTAAS) (model Z5000, Hitachi, Tokyo, Japan) at the Laboratory of Nutrition -Minerals at the Pharmaceutical Sciences School of the University of São Paulo (USP). All materials used during the analysis and dosage of selenium were demineralized with a 30% nitric acid bath for at least 12 hours and rinsed 10 times consecutively with deionized water.…”
