title: Circulating monocyte chemoattractant protein-1 in women with gestational diabetes.
abstract: Monocyte chemoattractant protein 1 (MCP-1) has been implicated as a key factor in the recruitment and activation of peripheral blood leukocytes in atherosclerotic lesions and adipose tissue. Elevated levels of circulating MCP-1 have been found in patients with type 1 and type 2 diabetes, as well as with coronary artery disease. In this study we compared serum MCP-1 concentrations between pregnant women with normal glucose tolerance (NGT), gestational diabetes mellitus (GDM) and non-pregnant healthy women. The group studied consisted of 62 patients with GDM (mean age 30.1 +/- 5.0 years) at 29.0 +/- 3.5 week of gestation, 64 pregnant women with NGT (mean age 30.0 +/- 4.7 years) at 29.2 +/- 2.9 week of gestation and 34 non-pregnant healthy women (mean age 29.8 +/- 4.7 years). Serum MCP-1 concentration was measured using an enzyme - linked immunosorbent assay. Median MCP-1 concentrations did not differ significantly between women with GDM (median 342.3 [interquartile range 267.9-424.4] pg/ml) and NGT (338.0 [274.7-408.2] pg/ml), but were markedly lower than those found in non-pregnant women (485.2 [409.6-642.4] pg/ml, p<0.0001). After adjusting for glucose, the difference between pregnant and non-pregnant women remained highly significant (p<0.0001). In GDM patients MCP-1 levels correlated significantly with fasting glucose (r=0.2665, p=0.0363), insulin (r=0.4330, p=0.0004), HOMA-IR (r=0.4402, p=0.0003), ISQUICKI (r=-0.4402, p=0.0003), HbA1c (r=0.2724, p=0.0322), as well as with prepregnancy and current BMI (r=0.3501, p=0.0057 and r=0.3250, p=0.0106, respectively). Multiple regression analysis revealed that MCP1 concentrations were significantly predicted only by plasma glucose ( beta=0.3489, p=0.00004). Our results suggest that MCP1 levels are decreased in pregnant women, irrespective of their glucose tolerance status.
