IntroductionNonalcoholic 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.ObjectivesWe examined clinical and biochemical factors associated with serum PTX3 concentrations in patients with T2D with and without NAFLD.Patients And MethodsSerum material was obtained from 116 patients with T2D (mean age, 59.1 years), including 79 patients with NAFLD.ResultsMedian (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.ConclusionsReported associations of PTX3 level add new insight into possible mechanisms of its atherogenic actions.
