Abstract：Objective To investigate the expression levels of serum angiopoietin-2(ANGPT2),interleukin-23(IL-23),and chitinase-3 like-1 protein(YKL-40)in patients with psoriasis vulgaris and their relationship with disease activity.Methods A total of 96 patients with psoriasis vulgaris treated at Nanyang Central Hospital from October 2020 to October 2023 were se-lected as the case group,while 50 healthy volunteers served as the normal control group.Based on the psoriasis area and severity index(PASI),the case group was divided into mild,moderate,and severe subgroups.The differences in serum ANGPT2,IL-23,and YKL-40 levels between the case group and the normal control group,as well as among patients with different disease severity,were compared.The diagnostic value of serum ANGPT2,IL-23,and YKL-40,along with their combined detection,in assessing severity of psoriasis vulgaris was analyzed.Results Compared with the normal controls,the serum levels of ANGPT2,IL-23,and YKL-40 in the case group were significantly increased(P＜0.05).Logistic regression analysis showed that elevated serum levels of ANGPT2,IL-23,and YKL-40 were associated with the onset of psoriasis vulgaris(P＜0.05).The severe group had higher serum levels of ANGPT2,IL-23,and YKL-40 than the moderate and mild groups,while the moderate group had higher levels than the mild group(P＜0.05).In-creased erythrocyte sedimentation rate(ESR)and elevated serum levels of ANGPT2,IL-23,and YKL-40 were correlated positively with disease severity(P＜0.05).Pearson correlation analysis showed a positive correlation between serum levels of ANGPT2,IL-23,and YKL-40(r=0.47,0.81,respectively,both P＜0.001).ROC curve analysis indicated that serum levels of ANGPT2,IL-23,and YKL-40 had diagnostic value for disease severity in moderate-to-severe psoriasis vul-garis,with the highest diagnostic value observed in their combined detection.Conclusions The levels of serum ANGPT2,IL-23,and YKL-40 are elevated in patients with psoriasis vulgaris,and increase as the disease worsens.Their combined detection has the highest diagnostic value for as-sessing the severity of psoriasis vulgaris.
