Clinical Significance of Hematological Parameters and Inflammatory Indices in Patients with Lichen Planus

Abstract

Aim: Lichen planus (LP) is a chronic, T-cell–mediated inflammatory dermatosis that affects the skin and mucous membranes. However, the relationship between LP and systemic inflammatory biomarkers remains controversial. This study aimed to evaluate the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), Systemic Immune-Inflammation Index (SII), and Systemic Inflammatory Response Index (SIRI) in patients with LP, compare these parameters with healthy controls, and investigate their diagnostic discriminative value. Methods: In this retrospective study, 150 patients diagnosed with LP who presented to Sivas Numune Hospital between 1 August 2022 and 1 October 2025 were screened; after applying exclusion criteria, 52 LP patients and age- and sex-matched 52 healthy controls were included in the analysis. Demographic data and hemogram parameters were recorded for all participants, and NLR, PLR, SII, and SIRI were calculated using standard formulas. Diagnostic performance was assessed using a receiver operating characteristic (ROC) curve analysis. Results: The LP and control groups were similar in terms of age and sex distributions. The hemoglobin, NLR, PLR, SII, and SIRI levels did not differ significantly between the groups (p>0.05). None of the indices demonstrated significant diagnostic discrimination in the ROC analysis (AUC <0.60 for all parameters). A subgroup analysis of 15 patients with oral mucosal involvement also revealed no significant differences in systemic inflammatory indices. Conclusion: The findings indicate that LP does not substantially elevate the systemic inflammatory response, and hematological indices such as NLR, PLR, SII, and SIRI have limited value in diagnosing LP or distinguishing clinical variants such as oral involvement. These results support the view that LP is predominantly a localized immune-mediated inflammatory condition. Prospective studies with larger cohorts integrating molecular- and cytokine-based biomarkers are needed to better elucidate the systemic inflammatory profile of LP.
