Abstract:
Objective:To investigate the expressions and prognostic value of lysyl oxidase like protein 2(LOXL2),chemo-kine c-c-motif ligand 18(CCL-18)and chitinase protein 40(YKL-40)in connective tissue disease with pulmonary interstitial lesions.Methods:A total of 308 patients with connective tissue disease who were treated in the First Affiliated Hospital of Hebei North Univer-sity from July 2021 to February 2022 were selected,including 108 patients with pulmonary interstitial disease(pathological group),200 patients without pulmonary interstitial disease(non pathological group),and another 35 healthy volunteers as the control group.Serum levels of LOXL2,CCL-18 and YKL-40 were detected by ELISA;Logistic regression analysis was applied to analyze the factors affecting the prognosis of patients with connective tissue disease and pulmonary interstitial disease;the predictive value of serum LOXL2,CCL-18 and YKL-40 levels on the prognosis of patients with connective tissue disease and pulmonary interstitial disease was analyzed by receiver operating characteristic(ROC)curve analysis.Results:Compared with control group,the serum levels of LOXL2,CCL-18 and YKL-40 in patients with connective tissue disease in the non pathological group and the pathological group were obviously increased(P<0.05);the serum levels of LOXL2,CCL-18 and YKL-40 in patients with connective tissue disease in the le-sion group were higher than those in the non lesion group(P<0.05);compared with the survival group,the serum levels of LOXL2,CCL-18 and YKL-40 in patients with connective tissue disease and pulmonary interstitial disease in the death group were obviously higher(P<0.05);Logistic regression analysis showed that LOXL2,CCL-18 and YKL-40 were risk factors for the prognosis of patients with connective tissue disease and pulmonary interstitial disease(P<0.05);the area under the ROC curve(AUC)of the combined detection of serum LOXL2,CCL-18 and YKL-40 in predicting the prognosis of patients with connective tissue disease and pulmonary interstitial disease was 0.967,which was better than their respective independent prediction(Zcombined detection-LOXL2=1.735,P=0.041;Zcombined detection-CCL-18=2.481,P=0.007;Zcombined detection-YKL-40=2.008,P=0.022).Conclusion:The serum levels of LOXL2,CCL-18 and YKL-40 in patients with connective tissue disease and pulmonary interstitial disease are elevated,which has certain value in the prognosis evaluation of patients with connective tissue disease combined with pulmonary interstitial disease.
