Abstract

Introductionː The roles of anti-adhesive podocalyxin (PODXL), ant-angiogenetic tumstatin/Col-IVα3 and neuroinflammation and innate immunity modulator Chitinase 1 (CHIT-1) in the etiology of vitiligo have not been studied yet.

Objectives: This study was planned to detect changes in serum PODXL, tumstatin/Col-IVα3 and CHIT1 levels in vitiligo patients.

Methods: This case-controlled study was performed on a total of 50 patients, 25 with vitiligo and 25 healthy controls. Participants in the vitiligo and control groups were matched in pairs for age and sex. At least 8-10 hours of overnight fasting, venous blood samples were taken from the participants in both groups and serum levels of podocalyxin, tumstatin/Col-IVα3 and CHIT 1 levels were measured by sandwich enzyme immunoassay.

Results: In the classification made according to the vitiligo European Task Force evaluation criteria, 18 of 25 vitiligo patients were in the slowly progressive phase and 7 patients were in the active progressive phase. Serum podocalyxin levels increased significantly in the vitiligo group compared to the controls (7.03±2.09 ng/ml vs. 4.99±1.20 ng/ml, p<0.02). However, serum tumstatin levels in vitiligo patients showed a significantly lower course compared to controls (4.88±1.76 ng/ml vs. 6.05±2.19 ng/nl, p<0.03). Serum CHIT-1 levels of vitiligo patients (42.4±7.22 ng/ml) were found to be significantly higher than the serum levels of the control group (34.5±5.33 ng/ml) (p<0.01).

Conclusion: Increased podocalyxin and CHIT1 levels versus decreased tumstatin levels are new biomarkers that support the role of anti-adhesive, anti-angiogenic and neuroinflammatory pathways in the formation of vitiligo.
