Neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios as inflammatory markers in psoriasis: a case-control study.

Our case-control study of 60 patients with psoriasis vulgaris (PsV), 20 patients with psoriatic arthritis (PsA), and 34 healthy control participants in Ho Chi Minh City Hospital of Dermato-Venereology from October 2019 to September 2020 aimed to evaluate the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and associated factors in patients with PsV and PsA. Results showed that in the PsV group, significant correlations of NLR with Psoriasis Area and Severity Index and the high-sensitivity C-reactive protein (hs-CRP) level was noted (r=0.374 and r=0.
