The purpose of this study is to clarify the association between the development of bronchopulmonary dysplasia in preterm infants and cytokines in the IL-33 pathway. In a collaborative study with major NICU facilities in Shikoku, we will compare serum IL-33 concentrations at corrected 36 weeks between groups of preterm infants requiring respiratory support who are born at less than 30 weeks' gestation and those who does not develop chronic lung disease as the primary endpoint. The secondary endpoint will be the IL-33 pathway including IL-4, IL-5, IL-13, and TSLP at 36 weeks by multiplex assay. Cytokines such as IL-6, IL-8, VEGF, and TNF-alpha in the acute phase will also be examined as biomarkers of bronchopulmonary dysplasia . If the relationship between IL-33 pathway and bronchopulmonary dysplasia is clarified by this study, IL-33 antibody (Itepekimab) and IL-4/13 antibody (Dupilumab) targeting IL-33 pathway may be candidates for treatment and may improve the prognosis of bronchopulmonary dysplasia .
