The Ministry of Health, Labour and Welfare (Japan) has approved research into primary pulmonary hypertension (PPH) and pulmonary hypertension due to chronic thromboembolic and/or embolic disease (CTE-PH) to examine their epidemiology, pathophysiology, and develop new therapeutic strategies. The Respiratory Failure Research Group, with grant support from the Ministry of Health, Labour and Welfar...
We report a case of neonatal Graves' disease involving an infant with severe persistent pulmonary hypertension (PPHN) associated with neonatal thyrotoxicosis that necessitated extracorporeal membrane oxygenation. Hyperthyroidism, although uncommon in the newborn period, has been associated with pulmonary hypertension among adults. The exact mechanisms responsible for this effect on pulmonary va...
Persistent pulmonary hypertension of the newborn (PPHN) is a clinical disorder characterized by abnormal vascular structure, growth, and reactivity. Disruption of vascular growth during early postnatal lung development impairs alveolarization, and newborns with lung hypoplasia often have severe pulmonary hypertension. To determine whether pulmonary hypertension can directly impair vascular grow...
BACKGROUND Limited data are available describing paediatric pulmonary arterial hypertension. AIMS To characterize the epidemiology, management and impact on quality of life and outcome of paediatric pulmonary arterial hypertension, excluding persistent pulmonary hypertension of the newborn and pulmonary arterial hypertension caused by congenital heart disease. METHODS In this multicentre st...
Although vascular endothelial growth factor (VEGF) plays a vital role in lung vascular growth in the embryo, its role in maintaining endothelial function and modulating vascular structure during late fetal life has not been studied. We hypothesized that impaired lung VEGF signaling causes pulmonary hypertension, endothelial dysfunction, and structural remodeling before birth. To determine wheth...
