Serum Visfatin, Fetuin-A, and Pentraxin 3 Levels in Patients With Psoriasis and Their Relation to Disease Severity.

BACKGROUND

Psoriasis is a chronic immune-mediated inflammatory skin disease associated with increase of some pro-inflammatory mediators. We wanted to investigate whether there is a relationship between psoriasis and visfatin, fetuin-A and pentraxin 3 (PTX3)-pro-inflammatory mediators implicated in the development of insulin resistance (IR), metabolic syndrome, and atherosclerosis.

METHODS

Visfatin, fetuin-A, and PTX3 concentrations were measured in 45 patients with plaque-type psoriasis and 45 healthy controls using enzyme-linked immunosorbent assay (ELISA).

RESULTS

Serum levels of visfatin, fetuin-A, and PTX3 in patients with psoriasis were found to be higher than in healthy controls (P = 0.002, P = 0.009, P < 0.001, respectively). Psoriasis area and severity index (PASI) score correlated significantly with visfatin and fetuin-A levels (P = 0.011, P = 0.040, respectively). There was a significant positive correlation between visfatin and fetuin-A (P < 0.001). PTX3 levels were correlated positively with homeostasis model assessment (HOMA-IR), insulin, triglyceride (TG), and very low density lipoprotein cholesterol (VLDL; P = 0.009, P = 0.007, P = 0.023, P = 0.024, respectively).

CONCLUSIONS

Increased serum visfatin, fetuin-A, and PTX3 levels, and the presence of positive correlation between visfatin, fetuin-A, and PASI score, probably reflect the inflammatory state and IR seen in psoriasis.
