BACKGROUND: Psoriasis is a chronic immune-mediated skin disorder. Systemic inflammation plays an important role in the pathogenesis of psoriasis.
METHODS: A total of 477 patients with psoriasis vulgaris (PsV, n = 347), generalized pustular psoriasis (GPP, n = 37), erythrodermic psoriasis (PsE, n = 45), arthritic psoriasis (PsA, n = 25) and mixed psoriasis (n = 23), and 954 healthy control subjects were included in the study. Demographic, clinical, and laboratory information were collected and compared between subgroups.
RESULTS: Compared with the healthy control group, patients with psoriasis had higher total white blood cell (WBC), neutrophil, platelet counts, neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR), but lower hemoglobin (Hb) levels, lymphocyte and red blood cell (RBC) counts. NLR values in the PsV group were significantly lower than those in the GPP, PsE, and PsA groups, with GPP group being the highest. PLR values in the PsV group were significantly lower than those in the GPP, PsE, and PsA groups. There was no significant correlation between the psoriasis area severity index (PASI) score and either the NLR or PLR in the PsV group.
CONCLUSIONS: Elevated NLR and PLR were associated with psoriasis and differed between subtypes, suggesting that they could be used as markers of systemic inflammation in psoriasis patients.
