C-reactive protein and metabotic syndrome in women with previous gestational diabetes

Background This study evaluates the presence of metabolic syndrome (MS) and its association with C-reactive protein (CRP) and other cardiovascular (CV) risk factors, in a sample of women with and without previous Gestational Diabetes (pGDM). Methods One hundred and sixty-six women with pGDM and 98 women (controls) with uncomplicated pregnancy were studied 16 months after delivery. in all women, plasma glucose, insulin, lipid profile, serum uric acid, C-reactive protein, fibrinogen and homocysteine were measured. MS was defined according to NCEP ATPIII criteria. Results MS was identified in 15 pGDM women (9%) versus 1 control (1%) 001). The more frequent metabolic traits were abdominal obesity (p < 0. (36% vs 17%) and low HDL-cholesterol (34% vs 17% in pGDM women and respectively; all p < 0.01). HOMA-R, LDL-cholesterol, fibrinogen, controls, serum uric acid and CRP resulted significantly higher in pGDM women with MS as compared to those without MS after adjustment for BMI. In women with no criteria for MS, only CRP levels were found to be higher in pGDM women compared to controls (p < 0.05). Seventeen percent of pGDM women with no criteria for MS had CRP levels >= 1 mg/L (all controls showed CRP levels < 1 mg/L). After a stepwise regression analysis, CRP levels were independently correlated to HOMA-R (r(2) = 0.27, p < 0.001) and fibrinogen (r(2) = 0.30, p < 0.001). Conclusions In our population, NIS occurs in a sizable proportion of pGDM women and is associated with increased levels of CRP, fibrinogen, uric acid and LDL-cholesterol. Moreover, higher levels of CRP, a marker of chronic low-grade inflammation, are present in a subset of women with pGDM, independently of MS. Copyright (c) 2006 John Wiley & Sons, Ltd.
