Abstract

Background: The selective destruction of melanocytes characterizes the persistent skin disorder known as vitiligo. A small percentage of the global population (0.5–2.0%) suffers from vitiligo, an acquired depigmentation disorder. Since it typically shows up on the face and other noticeable areas, it could be psychologically upsetting. One of the conserved families of mammalian chitinases is YKL-40, or chitinase-3-like protein 1. Aim of the Work: This study was set out to determine how vitiligo patients' serum levels of the inflammatory biomarker YKL-40 (CH3L1) varied with disease severity. Patients and Methods: Two groups were involved in this study: Forty vitiligo patients comprised the first group. They ranged in age from eighteen to fifty-nine and included both men and women. Forty healthy people served as control cases in the second group. They ranged in age from sixteen to fifty years old and included both boys and ladies. Results: As none of the vitiligo cases we looked at had any comorbidities, including skin or systemic diseases, our results suggest that YKL-40 may play a role in the etiology of vitiligo disease and demonstrate the clear elevation of this parameter in vitiligo patients. While a greater YKL-40 level may indicate systemic inflammation in vitiligo patients, it does not appear that YKL-40 concentration directly correlates with the degree of skin alterations. Additionally, YKL-40 seems to be a highly sensitive indicator of illness in vitiligo patients. After calculating the ideal serum YKL-40 cut-off value using the ROC curve, we found that this parameter was 100% sensitive and specific within our patient group. Conclusion: The fact that YKL-40 levels are higher in vitiligo patients raises the possibility that it plays a role in the onset of the disease.
