Abstract
Background: Rituximab (RTX) is utilized for treating connective tissue disease-associated interstitial lung disease (CTD-ILD) by eliminating pathogenic B cells, yet its clinical benefit remains debated. This study evaluates RTX's efficacy and safety in CTD-ILD.
Methods: A literature search was conducted in PubMed, Embase, and Cochrane Library for studies on RTX in CTD-ILD up to May 24, 2024. The Joanna Briggs Institute checklist assessed study quality. Changes in forced vital capacity (FVC%) and diffusing capacity of the lungs for carbon monoxide (DLCO%) before and after RTX use were compared, and analyzed between RTX and control groups.
Results: 1052 CTD-ILD patients from 40 studies were analyzed. RTX significantly improved FVC% (WMD = 7.10, 95% CI = 4.58-9.62, P < 0.05) and DLCO% (WMD = 5.26, 95% CI = 2.86-7.65, P < 0.01), and reduced the modified Rodnan skin score (mRSS) (WMD = -6.58, 95% CI = -8.27 to -4.89, P < 0.01) and prednisone dose (WMD = -6.94, 95% CI = -11.96 to -1.92, P < 0.01). Among RTX-treated patients, 30.3% improved, 45.3% remained stable, and 10.0% progressed. Adverse effects included infection (22.4%), hospitalization (6.7%), and mortality (5.0%).
Conclusions: RTX significantly enhances lung function in CTD-ILD patients, as shown in this systematic review and meta-analysis.
期刊介绍：
Postgraduate Medical Journal is a peer reviewed journal published on behalf of the Fellowship of Postgraduate Medicine. The journal aims to support junior doctors and their teachers and contribute to the continuing professional development of all doctors by publishing papers on a wide range of topics relevant to the practicing clinician and teacher. Papers published in PMJ include those that focus on core competencies; that describe current practice and new developments in all branches of medicine; that describe relevance and impact of translational research on clinical practice; that provide background relevant to examinations; and papers on medical education and medical education research. PMJ supports CPD by providing the opportunity for doctors to publish many types of articles including original clinical research; reviews; quality improvement reports; editorials, and correspondence on clinical matters.
