Abstract

In order to evaluate the relationship between peripheral white blood cell (WBC) count, insulin-mediated glucose uptake, and several risk factors for coronary heart disease (CHD), WBC, plasma glucose and insulin responses to a 75-g oral glucose challenge, fasting plasma cholesterol, high-density-lipoprotein (HDL)-cholesterol, and triglyceride concentration, and systolic and diastolic blood pressure were determined in 63 consecutive female volunteers with normal glucose tolerance. The results demonstrated the presence of statistically significant correlation coefficients between WBC count and both insulin-mediated glucose disposal (r = 0.50, P less than 0.001) and insulin response to oral glucose (r = 0.50, P less than 0.001). Furthermore, WBC count correlated with plasma glucose response to oral glucose (r = 0.48, P less than 0.001), fasting plasma triglyceride (r = 0.37, P less than 0.005) and HDL-cholesterol concentrations (r = -0.38, P less than 0.005), and systolic (r = 0.22, P less than 0.1) and diastolic (r = 0.27, P less than 0.05) blood pressure. However, the only two variables significantly correlated with WBC count in multivariate regression analysis were insulin resistance (r = 0.49, P less than 0.01) and insulin response (r = 0.35, P less than 0.05). These data indicate that WBC count is significantly correlated with changes in carbohydrate and lipoprotein metabolism and blood pressure that increase the risk of CHD. However, it appears that these relationships are secondary to resistance to insulin-mediated glucose uptake and hyperinsulinaemia.
