Association of serum IL-30 and soluble GP130 with the risk of psoriasis vulgaris.
The Egyptian journal of immunology(2024)
Abstract
Cytokines play a major role in the pathogenesis and progression of psoriasis. Interleukin (IL)-30 is a multifunctional cytokine. It binds to glycoprotein 130 (GP130) and inhibits the GP130 signaling pathways of psoriasis associated cytokines such as IL-6, IL-11, and IL-27. The study intended to assess associations of IL-30 and GP130 with the risk of psoriasis and Psoriasis Area Severity Index (PASI) score. Therefore, we measured the serum levels of IL-30 and GP130 in psoriasis patients and in a control group. An enzyme linked immunosorbent assay (ELISA) technique was used to measure IL-30 and GP130 levels in the serum of 43 patients and 43 normal controls. Statistical analysis of IL-30 and GP130 serum levels among patients and control groups and their correlation with PASI scores were performed. IL-30 serum levels showed a significant increase in patients with psoriasis compared with controls (p < 0.001) and a positive correlation with PASI scores. While serum levels of GP130 were not different in psoriatic patients and in the control group. Furthermore, the receiver operating characteristic (ROC) curve showed that IL-30 had diagnostic ability for prediction of psoriasis in comparison to controls, at cut of point of >14.34 showed a sensitivity of 97.7%, 100% specificity. In conclusion, IL-30 was elevated in psoriasis patients than controls, therefore, it can be considered a sensitive biomarker for diagnosis of psoriasis.
