Background To investigate the link between carbamylated low-density lipoprotein (ca-LDL), atherogenic index of plasma (AIP), atherogenic coefficient (AC), Castelli's risk indices I and II (CRI I and II) and subclinic atherosclerosis in psoriatic arthritis (PsA). Methods Thirty-ninepatients and 19 age, sex, body mass index matched healthy controls were included. Insulin resistance (IR) was assessed with homeostasis of model assessment-IR (HOMA-IR). Carotid intima-media thickness (CIMT) was measured at both common carotid arteries and mean CIMT was calculated. Results The mean age was 49.50 +/- 11.86 years and 64.1% were females in PsA group. In the PsA group, CIMT and HOMA-IR were significantly higher (p = 0.003, p = 0.043, respectively). AIP, AC, TG/HDL, CRI-1, CRI-2 and ca-LDL levels were similar between groups. In PsA group, CIMT was positively correlated with HOMA-IR, TG/HDL and AIP. Although ca-LDL was positively correlated with serum amyloid A (r = 0.744, p < 0.001), no correlation was detected between ca-LDL and CIMT (r = 0.215, p = 0.195). PsA patients with IR tended to have higher ca-LDL levels than patients without IR, but this difference lacked statistical significance (33.65 +/- 26.94, 28.63 +/- 28.06, respectively, p = 0.237). Conclusions A significant increase in CIMT was seen in PsA patients without clinically evident cardiovascular disease or any traditional atherosclerosis risk factors. CIMT was correlated with HOMA-IR, TG/HDL and AIP.
