Plasma visfatin levels in subjects with different states of glyeemia and its related factors

Fasting plasma visfatin was determined in subjects with various types of glucose tolerance. Visfatin level was (17.64±1.37)μg/L in subjects with normal glucose tolerance,and rose to (27.42±1.34) μg/L(P<0.05) in those with impaired glucose tolerance or impaired fasting glucose, and to(26.55 ± 1.64) μg/L(P< 0.05)in diabetic patients. No difference was found between obese and non-obese subjects. Positive correlation existed between visfatin and HbA1c(r=0. 317,P<0.01). Multiple linear step-wise regression showed that HbA1c and fasting plasma glucose had independent relation with the visfatin level. The result suggests that plasma visfatin may be related to glueometabolism and may play a role in the development of type 2 diabetes. Key words: Visfatin;  Diabetes mellitus,type 2;  Obesity
