The human reports of diverse relationships between different serum lipid levels and peripheral total leukocyte count and a unique lower peripheral monocyte count in hypercholesterolemia have driven us to think that, in human beings, peripheral differential leukocyte counts may be influenced differently by different types of hyperlipidemia and may have different relationships with various serum lipid levels. This is the main reason and purpose of this study. Our subjects were selected from Taipei residents who attended a regular health check program in our hospital in 1998. A total of 3282 subjects were enrolled, including 1677 normolipidemic, 960 untreated borderline hyperlipidemic, and 645 untreated hyperlipidemic subjects. By one-way ANOVA, we found that different types of hyperlipidemia were associated with significant differences in differential leukocyte counts. In hypertriglyceridemia, the total leukocyte count and counts of all leukocyte subtypes were significantly higher than those in normolipidemia. ; 醫學系內科 ; 醫學系 ; 醫學院 ; 期刊論文
