Abstract

Background.

Vasculitis represents a specific pattern of inflammation of the blood vessel wall that can occur in any organ system of the body. The neutrophil to lymphocyte ratio (NLR) and red blood cell distribution width (RDW) are currently used as markers of inflammation in several diseases.

Objectives.

This study analyzed C-reactive protein level (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC), NLR, and RDW in patients who had cutaneous vasculitis, or cutaneous vasculitis with systemic involvement, and in healthy controls.

Methods.

A total of 85 individuals were included in our study: 45 with vasculitis and 40 healthy controls. Patients who had complete blood count (CBC) analysis, CRP, and ESR at the time of skin biopsy were included in the study. NLR was calculated from these parameters.

Results.

NLR, CRP, ESR, and WBC were significantly higher in patients with vasculitis than in healthy controls (p≤0.05), but RDW did not significantly differ between the two groups.

Conclusions.

This study suggests that blood NLR may be used for predicting vasculitis, especially cutaneous vasculitis with systemic involvement.
