Description
Summary:Psoriasis is an immune-mediated disease, with various triggering factors, genetic predisposition, and an altered immune response concurring in the development of this disease. The eosinophil is a cell with an important role in various kinds of inflammatory processes. Scarce data are available regarding the role of the eosinophil in psoriasis. This study aims to address the overall relationship between eosinophil-count-derived inflammatory markers and psoriasis severity. There were 366 patients fulfilling the inclusion criteria included in this retrospective study and they were divided based on the body surface area (BSA) scale in mild and moderate-to-severe psoriasis. White blood cell (WBC), neutrophil, lymphocyte, monocyte, and eosinophil count, along with eosinophil-to-monocyte ratio (EMR) and eosinophil-to-neutrophil ratio (ENR) differed significantly between the two study groups. Eosinophil count, EMR, and ENR negatively correlated with disease severity. ENR is the most reliable eosinophil-count-derived marker in assessing psoriasis severity with an AUC of 0.627 and a cut-off value of 0.03. Eosinophil-count-derived inflammatory markers’ usefulness in appreciating disease severity was assessed for the first time in the literature in this study and proved to be reliable for the eosinophil count, EMR, and ENR.
