PURPOSE: Congenital diaphragmatic hernia (CDH) presents with a broad spectrum of severity, depending on the degree of pulmonary hypoplasia and persistent pulmonary hypertension (PPH). It is currently not clear whether pulmonary hypertension may affect late morbidity. Aim of the present study was to evaluate the influence of PPH on mid-term morbidity in high-risk CDH survivors. METHODS: All high-risk (prenatal diagnosis and/or respiratory symptoms within 6 h of life) CDH survivors, treated between 2004 and 2008 in our Department were followed up in a multidisciplinary outpatient clinic as part of a longitudinal prospective study. Auxological, gastroesophageal, pulmonary and orthopedic evaluations were done at specific time-points (at 6, 12, and 24 months of age). Patients were grouped depending on the presence/absence of pulmonary hypertension (defined by expert pediatric cardiologists after echocardiography). Paired t-test and Fisher's exact test were used as appropriate. P < 0.05 was considered significant. RESULTS: 70 survivors out of a total of 95 high-risk CDH infants treated in our Department attended our follow-up clinic and were prospectively evaluated. 17 patients were excluded from the present study because no clear data was available regarding the presence/absence of PPH during the perinatal period. Moreover, 9 infants were not enrolled because they did not reach at least 6 months of age. A total of 44 survivors were finally enrolled since they met the inclusion criteria. 26 infants did not present with PPH during the first hospital admission, while 18 had PPH. The 2 groups did not differ with regard to any of the outcomes considered at follow-up (p > 0.2). CONCLUSION: In our cohort of high-risk CDH survivors, PPH was not found to affect late sequelae at mid-term follow-up. This may indicate that postnatal pulmonary development is not (always) influenced by perinatal PPH. Nevertheless, a longer follow-up and more patients are needed to properly quantify possible late problems in high-risk CDH survivors with associated neonatal PPH.

Abstract

It is currently not clear whether pulmonary hypertension may affect late morbidity. Aim of the present study was to evaluate the influence of PPH on mid-term morbidity in high-risk CDH survivors. METHODS: All high-risk (prenatal diagnosis and/or respiratory symptoms within 6 h of life) CDH survivors, treated between 2004 and 2008 in our Department were followed up in a multidisciplinary outpatient clinic as part of a longitudinal prospective study. Auxological, gastroesophageal, pulmonary and orthopedic evaluations were done at specific time-points (at 6, 12, and 24 months of age).
