A Comprehensive Consolidation of Data on the Relationship Between Surfactant Protein-B (SFTPB) Polymorphisms and Susceptibility to Bronchopulmonary Dysplasia

Le résumé fourni par la source

BACKGROUND: This meta-analysis aims to evaluate the potential link between common variations in the Surfactant Protein-B (SFTPB) gene and the risk of bronchopulmonary dysplasia (BPD) in preterm neonates. METHODS: All pertinent articles published prior to February 1, 2024, in PubMed, Web of Science, EMBASE, CNKI, and Scopus databases were reviewed. RESULTS: Nineteen case-control studies involving 1149 BPD cases and 1845 non-BPD controls, were analyzed. Combined data indicated a significant link between SFTPB -18 A > C and Intron 4 VNTR polymorphisms with increased BPD susceptibility, while the 1580 C > T polymorphism provides a protective impact on BPD initiation. CONCLUSIONS: Pooled data indicated a significant association between SFTPB -18 A > C and Intron 4 VNTR polymorphisms with increased BPD risk, whereas the 1580 C > T polymorphism confers protection. These findings suggest a genetic susceptibility to BPD, underscoring the complex interplay of different genetic elements in its development.
