UNLABELLED: Obesity is associated with increased inflammation. Creactive protein (CRP) and inflammation-sensitive plasma protein (ISPs) are inflammatory markers. Proinflammatory process may be influenced by high saturated fatty acid intake.
OBJECTIVE: The aim of the present study was to evaluate the role of saturated fatty acids load on postprandial circulating levels of PCR and ISPs (alpha1-antitrypsin, alpha1-acid glucoprotein, and fibrinogen) in obese women.
DESIGN: A total of 15 obese women (age = 31,7 +/- 4,5 years, BMI = 37,9 +/- 7,3 kg/m(2)) and 15 lean controls women (age = 30,6 +/- 4,6 years, BMI = 20,6 +/- 2,6 kg/m(2)) were recruited for this study. After and overnight fast subjects ate the fat load consisted of 75 g of fat (100% saturated fatty acid, 0% cholesterol), 5 g of carbohydrates, and 6 g of protein per m2 body surface area. Postprandial serum levels of CRP, alpha1-antitrypsin, alpha1-acid glucoprotein, and fibrinogen were measured. Anthropometry and blood biochemical parameters were measured in both groups.
RESULTS: The obese women had fasting serum PCR levels higher (p = 0,013) and fibrinogen (p = 0,04) than those of control women. Serum CRP and fibrinogen levels was positively related to body mass index (BMI) in obese group. There weren't differences in fasting serum alpha1- antitrypsin levels (p = 0,40), and alpha1-acid glucoprotein (p = 0,28) levels in obese group in comparison to lean control group. Serum CRP, alpha1-antitrypsin, alpha1-acid glucoprotein, and fibrinogen did not change postprandially (p = > 0,05 difference to fasting levels).
CONCLUSION: A high-saturated fatty acids load is not associated with serum CRP, alpha1-antitrypsin, alpha1-acid glucoprotein, and fibrinogen levels increase. Serum alpha1-antitripsin and alpha1-acid glucoprotein levels are not increased in obese women. Serum PCR and fibrinogen levels are increased in obese women, and are positively related to BMI.
