Selenium levels in first-degree relatives of diabetic patients.
The present study was conducted to evaluate the serum selenium levels in first-degree relatives of diabetic patients (FDR) according to controls. Insulin resistance, serum lipid levels, inflammation markers, and blood pressure were also studied in these patients. Serum levels of selenium in FDR were significantly lower than control group (74.65 +/- 5.9 vs 88.7 +/- 8.7 microg/dl, p < 0.0001). HsCRP, HOMA-IR, insulin, homocysteine levels were significantly higher in FDR according to the control group (1.32 +/- 0.9 vs 0.63 +/- 0.4 mg/dL, p < 0.0001; 2.07 +/- 0.84 vs 1.51 +/- 0.69, p < 0.0001; 9.26 +/- 3.8 vs 6.8 +/- 2.98 microU/MI, p < 0.0001; 15.7 +/- 7.4 vs 11.5 +/- 5.1 micromol/L, p < 0.0001, respectively). There was significant correlation between selenium levels and hsCRP (r = - 0.450, p < 0.0001). There was also weak significant correlation also between HOMA-IR and selenium levels (r = -0.227, p = 0.003). There was a correlation between systolic blood pressure and BMI (r = 0.365, p < 0.0001). But there was no correlation between selenium levels and blood pressure or other parameters. HsCRP, HOMA-IR, homocysteine levels in individuals with selenium levels < 80 microg/L (n = 78) was significantly higher than hsCRP HOMA-IR, homocysteine levels in individuals with selenium levels >or= 80 (n = 91; 1.23 +/- 0.98 vs 0.81 +/- 0.76 mg/dL, p < 0.003; 1.99 +/- 0.88 vs 1.64 +/- 0.74, p < 0.005; 15.0 +/- 7.6 vs 12.9 +/- 5.7 micromol/L, p < 0.049, respectively). Selenium deficiency may contribute to cardiovascular disease risk in FDR.
