目的

探讨抗合成酶综合征(ASS)相关间质性肺病(ILD)患者临床特征及疾病进展的相关因素。

方法

收集90例ASS-ILD患者的临床资料并进行回顾性分析。对患者进行随访,根据胸部HRCT检查结果将患者分为疾病进展组(n=23)和稳定组(n=67),根据血清学检查结果将患者分为抗Ro52抗体阳性组(n=76)和抗Ro52抗体阴性组(n=14)。比较各组的临床资料,采用Logistic回归模型分析影响ASS-ILD进展的危险因素。

结果

90例患者中进展组23例(25.6%),稳定组67例(74.4%)。进展组患者发热比例、ALT、AST、LDH、TnI、CRP、sFe、CA125基线水平、抗PL-7抗体阳性率、抗Ro52抗体阳性率及抗Ro52抗体高滴度比率高于稳定组(P<0.05)。进展组基线FVC%、DLCO%显著低于稳定组(P<0.05),复发次数及基线激素使用剂量显著高于稳定组(P<0.05)。据多因素Logistic回归分析显示,发热、基线FVC%及DLCO%低、复发次数多、高滴度抗Ro52抗体是ASS-ILD进展的独立危险因素(P<0.05)。在90例患者中,抗Ro52抗体阳性76例(84.4%),阴性14例(15.6%)。与抗Ro52抗体阴性组相比,抗Ro52抗体阳性组雷诺现象更多见,发热频率更高,ESR、CRP、sFe、CA125基线水平更高,复发次数更多,而基线FVC%及DLCO%值更低,差异有统计学意义(P<0.05)。

结论

发热、基线肺功能低和复发次数多、高滴度抗Ro52抗体是ASS-ILD进展的独立危险因素。抗Ro52抗体阳性的ASS-ILD患者表现出更高的炎症反应和更差的基线肺功能,抗Ro52抗体阳性患者应加强炎症指标及肺功能监测。

Objective

To investigate the association of anti-Ro52 antibody with the clinical features and disease progression of anti-synthetase syndrome (ASS) associated interstitial lung disease (ILD).

Methods

Clinical data were obtained and reviewed from 90 patients with ASS-ILD. All patients were followed, and based on high-resolution computed tomography (HRCT) findings, they were divided into a disease progression group (n=23) and a stable group (n=67). According to serological results, the patients were further subdivided into an anti-Ro52 antibody positive group (n=76) and an anti-Ro52 antibody negative group (n=14). Clinical data were then compared between groups, and a Logistic regression model was used to analyze the risk factors affecting the progression of ASS-ILD.

Results

Of the 90 ASS-ILD patients, 23 (25.6%) were in the progressive group and 67 (74.4%) in the stable group. The proprotion of patients with fever, baseline levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), troponin I (TnI), C-reaction protein (CRP), serum ferritin (sFe), and serum carbohydrate antigen 125 (CA125), as well as the positive rates of anti-Ro52 and anti-PL-7 antibodies and the proportion of patients with a high titer of anti-Ro52 antibody were significantly higher in the disease progression group than in the stable group (P<0.05). Baseline forced vital capacity (FVC%) and diffusion capacity of carbonmonoxide (DLCO%) was significantly lower in the progression group, whereas the frequency of relapse and baseline glucocorticoid dose were significantly higher (P<0.05). Multivariate logistic regression analysis identified fever, low baseline lung function, more relapses, and a high titer of anti-Ro52 antibody were risk factors for the progression of ASS-ILD (P<0.05). Among the 90 patients, 76 (84.4%) were positive for anti-Ro52 antibodies, and 14 (15.6%) tested negative. Compared with the anti-Ro52 antibody-negative group, the positive group had a higher prevalence of Raynaud's phenomenon, a higher frequency of fever, elevated baseline levels of ESR, CRP, sFe, and CA125, and more frequent relapses (P<0.05). In contrast, baseline FVC% and DLCO% were significantly lower in the anti-Ro52 antibody positive group (P<0.05).

Conclusion

Fever, low baseline lung function, more relapses, and a high titer of anti-Ro52 antibody are risk factors for the progression of ASS-ILD. Patients with anti-Ro52 antibody positive ASS-ILD exhibit more pronounced inflammation and worse baseline lung function. Therefore, closer monitoring of inflammatory markers and pulmonary function should be implemented in this patient population.
