Association of leukocyte count and hsCRP with metabolic abnormalities in subjects with normal glucose tolerance (CURES - 64).
OBJECTIVE
The aim of the present study was to assess the association of leukocyte count and high sensitivity C-Reactive protein (hsCRP) with metabolic abnormalities in subjects with normal glucose tolerance.


METHODS
Subjects with Normal Glucose Tolerance (NGT) (n = 865) were recruited from the Chennai Urban Rural Epidemiology Study [CURES]. Standard methods were used for assessing hsCRP [Nephelometry, in a subset] and leukocytes [Flowcytometry, Sysmex SF-3000]. Insulin resistance was calculated using the Homeostasis Assessment model (HOMA-IR).


RESULTS
Body mass index, waist circumference, systolic and diastolic blood pressure, fasting plasma glucose, HbA1c, serum cholesterol, LDL cholesterol, HOMA IR and hsCRP increased significantly with increasing tertiles of leukocyte count [p for trend < 0.001]. Both leukocyte count and hsCRP showed a positive correlation with cardiovascular risk factors. Leukocyte count showed a positive correlation with hsCRP [p = 0.008]. Both mean leukocyte count [p < 0.001] and hsCRP [p = 0.04] were higher in subjects with Metabolic Syndrome (MS), which increased with increase in number of metabolic abnormalities [p for trend < 0.001]. Regression models showed leukocyte count [p < 0.001] and hsCRP [p = 0.03] to be associated with MS, even after adjusting for age and gender.


CONCLUSIONS
A significant association exists between systemic inflammation [leukocyte count and hsCRP] and MS/cardiovascular risk factors in Asian Indians even among non-diabetic subjects.
