ABSTRACT
Among the proteins secreted by adipocytes, acylation stimulating protein (ASP), which plays a crucial role in energetic balance regulation, merits particular attention. ASP is a protein of the C3 complement system, responsible for glucose and lipids metabolism in an insulin-independent mechanism. ASP's role during pregnancy and its interactions with pregnancy hormones remains unknown. The lipogenic character of ASP may impose a question as to what extent this hormone participates in pregnant women lipogenesis, and what is the basal and postprandial ASP secretion during the second trimester of pregnancy. The results of the examinations of 26 pregnant women during the second trimester of their first pregnancy were analyzed. Due to the limited data available in the literature, a control group was examined. The group consisted of 8 healthy non-pregnant patients within similar age ranges. Blood samples were collected in order to determine ASP, total cholesterol, HDL, LDL and triglyceride levels. Basal ASP levels present in obese pregnant women (group OBP; 30.20 +/- 2.13 ng/mL) were significantly higher than those in the healthy control group (group LnP; 20.49 +/- 1.97 ng/mL), P<0.05. Mann-Whitney U test- analysis of these group differences indicated that OBP patients had significantly higher ASP levels than controls at 30 (P<0.01), 60 (P<0.01), and 120 (P<0.01) min after a meal. After a meal, the incremental ASP area under the curve in group OBW patients was significantly higher from that observed in control group LnP (718,9 +/- 263,9 ng/mL x 2h vs. 35,1 +/- 14,6 ng/mL x 2h, P<0.05). Basal concentration of triglycerides, total cholesterol and LDL cholesterol were significantly higher in all pregnant women compared to the group of non-obese non-pregnant women. It was found that lipid parameters were highly dependent upon body mass gain during pregnancy. Group OBP demonstrated significantly higher basal concentrations of all parameters of lipid metabolism in comparison with the remaining groups of pregnant patients. In conclusion, we found abnormalities of ASP and lipid profiles in lean, overweight, and obese pregnant women strictly connected with obesity. Acylation stimulating protein correlated with lipid parameters, suggesting increased risk of dyslipidemia in obese pregnant women.
