N2 - Objective: Pregnancy-associated plasma protein-A (PAPP-A) has been implicated in the atherosclerotic process through regulation of local expression of IGF1. In type 2 diabetes mellitus, glycaemic control has been involved in PAPP-A expression. We compared PAPP-A, IGF1, inflammatory markers and adiponectin concentrations in type 2 diabetic patients with and without carotid plaques and evaluated the relationship between these serum parameters and ultrasound carotid markers of atherosclerosis. Methods: We studied 125 consecutive type 2 diabetic patients. Clinical data, metabolic variables, hemostatic factors (plasma type-1 plasminogen activator inhibitor, fibrinogen), high-ultrasensitive C reactive protein (hsCRP), tumor necrosis factor (TNF)-α, interleukin (IL)-6, adiponectin, IGF1 and PAPP-Awere determined. Patients were classified into two groups according to the presence of carotid plaques on ultrasound. Carotid intima-media thickness (IMT) and morphology of carotid plaques were evaluated. Results: The mean age was 61.5±7.3 years and the mean glycated hemoglobin of 6.8±0.9%. A total of 60% presented carotid plaques. Both groups were homogeneous in anthropometric data, biochemical determinations and hemostatic factors. Adiponectin, hsCRP, TNF-α and IL-6 were similar in both groups. No differences were observed in serum PAPP-A (0.46 (0.22-0.86) vs 0.38 (0.18-0.66) mIU/l and in SDS IGF1 (-0.34±1.38 vs-0.67±1.35)) in patients with and without carotid plaques respectively. PAPP-A and IGF1 were not correlated with IMT. Conclusions: Serum PAPP-A and IGF1 do not appear to be useful serum biomarkers for carotid atherosclerosis in type 2 diabetic patients with stable glycemic control, despite scientific evidence of their local role in atherosclerosis. © 2009 European Society of Endocrinology.
