Chest x-ray showing established BPD with widespread interstitial shadows in both lung fields, consistent with fibrosis. Serum levels of seven cytokines in premature ventilated newborns: Treated infants received decreasing concentrations of nitric oxide, beginning at 20ppm for 48 to 96 hours, and the doses were subsequently decreased to doses of 10, 5, and 2 ppm at weekly intervals, for a minimum of 24 days.

Vascular endothelial growth factor and hepatocyte growth factor levels are differentially elevated in patients with advanced retinopathy of prematurity.
Pneumopericardium Persistent fetal circulation. Integration of basic and clinical research will lead to novel therapies effective in the prevention and treatment of BPD. Fatores que independentemente aumentaram o risco broncofisplasia First characterized by Northway and colleagues inBPD has traditionally been defined as the presence of persistent respiratory signs and symptoms, the broncodisplwsia for supplemental oxygen to treat hypoxemia, and an abnormal chest radiograph at 36 weeks post menstrual age gestational age plus chronological age 8 Table 1 9.
Conclusion Nearly 40 years after its original description, BPD remains a major complication of premature birth and a challenge for the future.
Elevated cytokine concentrations have been observed in tracheal aspirates 3940 and serum 4142 of infants with respiratory distress syndrome and predict the subsequent development of BPD.
Hyperoxic injury decreases alveolar epithelial cell expression of vascular endothelial growth factor VEGF nfonatal neonatal rabbit lung. While the strongest association is with preterm birth, other factors such as prenatal infection and inflammation, mechanical ventilation, oxygen toxicity with decreased host antioxidant pul,onar, patent ductus arteriosus and postnatal infection all contribute to the pathogenesis of BPD.
Of the available strategies to treat pulmonary hypertension, iNO is the safest and most effective treatment. Increase in the concentration of transforming growth factor beta-1 in bronchoalveolar lavage fluid before development of chronic lung disease of prematurity.
Long-term exposure to a symptomatic PDA, worsens pulmonary morbidity More recent studies have expanded on these findings demonstrating that this inflammatory milieu can alter cell signaling pathways important in lung branching morphogenesis.

These studies will further inform the debate. Instead, there are usually uniformly dilated acini with thin alveolar septa and little or no interstitial fibrosis.

Surfactant proteins are important for regulating surfactant activity and innate host defense and genetic variants in surfactant proteins may increase risk for BPD. For this reason bone marrow derived cells have great therapeutic potential in bronchopulmonary dysplasia. The major effect of inhaled betamethasone in a multicentre randomised trial was to decrease the perceived need for the use of systemic steroids 79 – Table 1 NIH diagnostic criteria for bronchopulmonary dysplasia 9.
Mechanical ventilation is an essential treatment for extremely preterm infants at the border of viability.
