Elevated levels of plasma pentraxin 3 (PTX3), a marker of inflammation, are associated with the risk of developing cardiovascular diseases in the general population, as well as in patients with type 2 diabetes (DM2). In this study, we aimed to determine factors associated with PTX3 serum concentrations in men and women with DM2. The study included 116 consecutive patients (67 men and 49 women) with DM2 from an outpatient diabetic clinic. Men were characterised by lower age and higher uric acid, creatinine and bilirubin concentrations and waist/hip ratio than women. In women, low-density lipoprotein cholesterol (LDL-C) levels were higher than in men. In men, median (interquartile range) values of PTX3 concentration were 4.02 (1.99), and in women they were 4.53 (3.31) ng/ml (NS). In men, PTX3 concentrations correlated with total cholesterol (TC), triglycerides, apolipoprotein (Apo) C3, Apo B48, Glc and creatinine levels. In women, PTX3 correlated significantly with TC and LDL-C and Apo B100. Partial regression analysis revealed that after adjusting for age, PTX3 concentrations in men were significantly associated with TC, LDL-C, triglycerides, creatinine, Apo C3 and Apo B48, while in women they were associated with TC, LDL-C and Apo B100. The results could be of importance in sex-specific prevention of vascular complications in DM2 patients.

Introduction: Nonalcoholic fatty liver disease (NAFLD) is common in patients with type 2 diabetes (T2D). Pentraxin 3 (PTX3), a marker of inflammation, is a cardiovascular risk factor., Objectives: We examined clinical and biochemical factors associated with serum PTX3 concentrations in patients with T2D with and without NAFLD., Patients and Methods: Serum material was obtained from 116 patients with T2D (mean age, 59.1 years), including 79 patients with NAFLD., Results: Median (interquartile range) PTX3 level was 4.264 (2.293) ng/ml in patients with and 3.773 (3.223) ng/ml in patients without NAFLD (P = 0.93). In the whole group, PTX3 level was associated with total cholesterol, low‑density lipoprotein cholesterol (LDL‑C), apolipoprotein (apo) B100, apo C3, triglyceride (TG) concentrations, and waist circumference after adjustment for age and gender. As indicated by partial regression coefficient b, increase of independent variable LDL‑C by 1 mmol/l was associated with the rise of PTX3 by 1.2017 ng/ml, increase of apo B100 by 1 mg/dl with the rise of PTX3 by 1.0051 ng/ml, and increase of apo C3 by 1 μg/dl with the rise of PTX3 by 1.0012 ng/ml. In patients with T2D with NAFLD, total cholesterol, LDL‑C, TG, apo C3, and apo B100 were associated with PTX3. Associations of PTX3 with apolipoproteins were observed only in the NAFLD group., Conclusions: Reported associations of PTX3 level add new insight into possible mechanisms of its atherogenic actions.
