摘要
目的分析结缔组织病(CTD)相关间质性肺炎(IP)患者治疗前后血清Dickkopf相关蛋白1(DKK-1)、潜在转化生长因子结合蛋白2(latent transforming growth factor binding protein 2,LTBP2)表达水平变化及其与疾病活动度和预后的关系。方法收集2022年1月~2023年10月河北北方学院附属第一医院收治的121例CTD患者,按照IP发生情况分为观察组(CTD相关IP患者,n=62)和对照组(CTD无IP患者,n=59);观察组依照疾病活动度分为稳定期组(n=26)和急性加重期组(n=36)。采用酶联免疫吸附试验(ELISA)检测血清DKK-1,LTBP2水平;采用Pearson或Spearman分析急性加重期CTD相关IP患者血清DKK-1,LTBP2水平与临床资料的相关性;采用Logistic回归分析CTD相关IP患者病情急性加重的影响因素。结果观察组血清DKK-1(14.98±3.32 ng/ml),LTBP2(32.64±4.01ng/ml)水平高于对照组(2.21±0.67 ng/ml,8.73±2.15 ng/ml),差异具有统计学意义(t=28.983,57.518,均P<0.05)。急性加重期组磨玻璃影占比(66.67%)、蜂窝影患者占比(52.78%)及血清DKK-1(19.67±4.10 ng/ml),LTBP2(38.76±4.92 ng/ml),C反应蛋白(CRP)(32.46±3.12 mg/L)水平高于稳定期组(30.77%,23.08%,8.48±1.37 ng/ml,24.17±3.65 ng/ml,22.05±2.80 mg/L),差异具有统计学意义(t/χ^(2)=7.790,5.534,13.362,12.781,13.524,均P<0.05)。急性加重期CTD相关IP患者治疗前血清DKK-1,LTBP2水平与磨玻璃影、蜂窝影、CRP,疾病活动度呈正相关(r=0.526,0.518,0.513,0.548;0.499,0.514,0.520,0.561,均P<0.05)。随着治疗时间延长,稳定期组和急性加重期组CTD相关IP患者血清DKK-1,LTBP2水平均下降,且治疗前、治疗1个月后、治疗3个月后急性加重期组血清DKK-1,LTBP2水平均高于稳定期组,差异具有统计学意义(t=13.355,13.206,15.913;12.781,12.263,11.161,均P<0.05)。DKK-1[OR(95%CI):2.458(1.297~4.657)],LTBP2[OR(95%CI):2.739(1.567~4.789)]是CTD相关IP患者病情急性加重的独立危险因素(均P<0.05)。结论CTD相关IP患者血清DKK-1,LTBP2水平显著升高,与疾病活动�
Objective To analyze the changes in the expression levels of serum Dickkopf-related protein 1(DKK-1)and latent transforming growth factor binding protein 2(LTBP2)in patients with connective tissue disease(CTD)related interstitial pneumonia(IP)of different disease activity levels before and after treatment.Methods A total of 121 CTD patients who visited the First Affiliated Hospital of Hebei North University from January 2022 to October 2023 were collected and separated into an observation group(CTD-related IP patients,n=62)and a reference group(CTD without IP patients,n=59)based on the incidence of IP.The observation group was separated into a stable phase group(n=26)and an acute exacerbation phase group(n=36)based on disease activity.Enzyme-linked immunosorbent assay(ELISA)detected DKK-1 and LTBP2 levels.Pearson or Spearman were used to analyze correlations between DKK-1 and LTBP2 levels with clinical data.Logistic regression was applied to analyze influencing factors of acute exacerbation in CTD-related IP patients.Results The serum levels of DKK-1(14.98±3.32 ng/ml)and LTBP2(32.64±4.01 ng/ml)in the observation group were higher than those in the reference group(2.21±0.67 ng/ml,8.73±2.15 ng/ml),the differences were statistically significant(t=28.983,57.518,all P<0.05).The proportions of patients with ground glass opacity(66.67%)and honeycomb opacity(52.78%),serum DKK-1(19.67±4.10 ng/ml),LTBP2(38.76±4.92 ng/ml)and C-reactive protein(CRP)(32.46±3.12 mg/L)in the acute exacerbation group were higher than those in the stable phase group(30.77%,23.08%,8.48±1.37 ng/ml,24.17±3.65 ng/ml,22.05±2.80 mg/L),the differences were statistically significant(t/χ^(2)=7.790,5.534,13.362,12.781,13.524,all P<0.05).The serum levels of DKK-1 and LTBP2 in patients with acute exacerbation of CTD-related IP after treatment were positively correlated with ground glass opacities,honeycomb opacities,CRP and different disease activity(r=0.526,0.518,0.513,0.548;0.499,0.514,0.520,0.561,all P<0.05).As the treatment time extended,the
