Relationships between C-reactive protein, white blood cell count, and insulin resistance in a Chinese population.
Summary of "Relationships between C-reactive protein, white blood cell count, and insulin resistance in a Chinese population."
This study is to clarify whether C-reactive protein (CRP) and white blood cell (WBC) count influence insulin homeostasis to the same degree. Serum CRP and peripheral WBC were measured in 739 subjects with normal glucose regulation, 512 with impaired glucose regulation, and 502 newly diagnosed diabetic patients. Levels of insulin resistance (IR) were assessed using the index of homeostasis model (HOMA-IR). Serum CRP and WBC were significantly correlated with HOMA-IR and risk factors of IR. Relative risks of IR for each 1-SD increase of Ln (CRP) and Ln (WBC) were 1.28 (1.10-1.47) and 1.15 (1.01-1.31), respectively after adjustment for age, sex, obesity measurements, and other traditional risk factors. Additional adjustment for WBC slightly attenuated the association between CRP and IR [1.25 (1.08-1.45); P = 0.003] whereas adjustment for CRP substantially attenuated the association of WBC with IR toward null (P = 0.134). Moreover, individuals with both high levels of CRP and WBC were at higher risks of IR than those with high CRP or WBC alone. Both CRP and WBC were significantly associated with risks of IR. CRP might be a more effective biomarker in terms of the association with IR.

Medical and Biotech [MESH] Definitions
Leukocyte Count
The number of WHITE BLOOD CELLS per unit volume in venous BLOOD. A differential leukocyte count measures the relative numbers of the different types of white cells.
Blood Cell Count
The number of LEUKOCYTES and ERYTHROCYTES per unit volume in a sample of venous BLOOD. A complete blood count (CBC) also includes measurement of the HEMOGLOBIN; HEMATOCRIT; and ERYTHROCYTE INDICES.
Reticulocyte Count
The number of RETICULOCYTES per unit volume of BLOOD. The values are expressed as a percentage of the ERYTHROCYTE COUNT or in the form of an index ("corrected reticulocyte index"), which attempts to account for the number of circulating erythrocytes.
Semen Analysis
The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.
Erythrocyte Count
The number of RED BLOOD CELLS per unit volume in a sample of venous BLOOD.
