Ge H, Liu W, Li H, et al. - Researchers intended to determine if there is an association between the blood contents of vitamin D/E in premature infants and bronchopulmonary dysplasia (BPD). The case group included 63 preterm infants with a clear diagnosis of BPD and 5 preterm infants who died before the diagnosis of BPD, while the control group included 65 non-BPD preterm infants with similar baseline characteristics. According to the findings, vitamin D and E levels in the serum of premature infants with BPD are lower, and this is linked to the severity of BPD. High levels of vitamin D and E are associated with a shorter duration of oxygen support. Vitamin D and E may have potential benefit in the prognosis and treatment of BPD.
