Interstitial lung disease (ILD), the main pulmonary manifestation of idiopathic inflammatory myopathy (IIM), frequently develops into rapidly progressive ILD (RP-ILD) with significantly worse prognosis. This meta-analysis identified risk and protective factors associated with developing RP-ILD in IIM patients.
PubMed, Embase, Web of Science, and Scopus (up to October 2024) were searched, analyzing 21 retrospective studies (2,099 patients). Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were collected. Subgroup analysis was performed based on the RP-ILD definition. Sensitivity analysis and publication bias assessments (Egger's test and trim-and-fill method) were performed.
The associated risk factors for RP-ILD development in IIM patients included age (OR = 1.014, 95% CI: 1.002-1.025), clinically amyopathic dermatomyositis (OR = 3.023, 95% CI: 1.491-6.130), mechanic's hands (OR = 1.421, 95% CI: 1.054-1.915), fever (OR = 3.090, 95% CI: 1.933-4.939), pulmonary infection (OR = 2.610, 95% CI: 1.457-4.677), anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibodies (OR = 6.044, 95% CI: 4.331-8.435), anti-Ro-52 antibodies (OR = 2.425, 95% CI: 1.807-3.255), and elevated levels of ferritin (OR = 5.844, 95% CI: 4.121-8.287), lactate dehydrogenase (OR = 3.627, 95% CI: 2.406-5.466), erythrocyte sedimentation rate (OR = 1.598, 95% CI: 1.089-2.344), aspartate aminotransferase (OR = 2.666, 95% CI: 1.864-3.814), alanine transaminase (OR = 2.702, 95% CI: 1.737-4.201), and C-reactive protein (OR = 3.366, 95% CI: 2.149-5.274), whereas longer disease duration (OR = 0.790, 95% CI: 0.638-0.977) and dysphagia (OR = 0.773, 95% CI: 0.653-0.916) were potential protective factors.
This meta-analysis of 21 retrospective studies identified potential risk and protective factors associated with RP-ILD development in IIM patients, providing a basis for early identification and management.

间质性肺病（ILD）是特发性炎性肌病（IIM）的主要肺部表现，常发展为快速进展性ILD（RP - ILD），预后明显更差。本荟萃分析确定了与IIM患者发生RP - ILD相关的风险和保护因素。
检索了PubMed、Embase、Web of Science和Scopus（截至2024年10月），分析了21项回顾性研究（2099例患者）。收集了合并比值比（OR）及95%置信区间（CI）。基于RP - ILD的定义进行亚组分析。进行了敏感性分析和发表偏倚评估（Egger检验和修剪填充法）。
IIM患者发生RP - ILD的相关危险因素包括年龄（OR = 1.014，95% CI：1.002 - 1.025）、临床无肌病性皮肌炎（OR = 3.023，95% CI：1.491 - 6.130）、技工手（OR = 1.421，95% CI：1.054 - 1.915）、发热（OR = 3.090，95% CI：1.933 - 4.939）、肺部感染（OR = 2.610，95% CI：1.457 - 4.677）、抗黑色素瘤分化相关基因5（抗MDA5）抗体（OR = 6.044，95% CI：4.331 - 8.435）、抗Ro - 52抗体（OR = 2.425，95% CI：1.807 - 3.255）以及铁蛋白水平升高（OR = 5.844，9% CI：4.121 - 8.287）、乳酸脱氢酶（OR = 3.627，95% CI：2.406 - 5.466）、红细胞沉降率（OR = 1.598，95% CI：1.089 - 2.344）、天冬氨酸转氨酶（OR = 2.666，95% CI：1.864 - 3.814）、丙氨酸转氨酶（OR = 2.702，95% CI：1.737 - 4.201）和C反应蛋白（OR = 3.366，95% CI：2.149 - 5.274），而病程较长（OR = 0.790，95% CI：0.638 - 0.977）和吞咽困难（OR = 0.773，95% CI：0.653 - 0.916）是潜在的保护因素。
这项对21项回顾性研究的荟萃分析确定了与IIM患者发生RP - ILD相关的潜在风险和保护因素，为早期识别和管理提供了依据。
