Pulmonary arterial hypertension (PAH) is a rare and progressive disorder. Current treatment in the pediatric population includes phosphodiesterase 5 inhibitors (PDE-5i), endothelin receptor antagonists (ERA), and both inhaled and intravenous prostacyclin pathway agonists. As of December 22, 2015 the first oral prostacyclin pathway agonist, selexipag (Uptravi(®)), was FDA approved in the US. In this case series, we discuss our single-center experience using selexipag in a pediatric population, composed of both patients with idiopathic PAH, and patients with congenital heart disease and PAH...

BACKGROUND: Pulmonary hypertension secondary to congenital heart disease is a common problem in pediatric patients presenting for open heart surgery. Milrinone has been shown to reduce pulmonary vascular resistance and pulmonary artery pressure in pediatric patients and neonates postcardiac surgery. We aimed to evaluate the postoperative outcome in such patients with three different fixed maintenance doses of milrinone. METHODOLOGY: Patients were randomized into three groups...

OBJECTIVE: To evaluate the long-term safety and effectiveness of tadalafil in pediatric patients with pulmonary arterial hypertension (PAH) in real-world clinical practice. METHODS: This is an observational surveillance of PAH patients receiving tadalafil in the contracted sites. We performed a subgroup analysis of 391 pediatric PAH patients (<18 years) who were included from 1,704 total patients in this surveillance. Safety was assessed from the frequency of adverse drug reactions (ADRs), discontinuations due to adverse events (AEs), and serious adverse drug reactions (SADRs)...

Pulmonary arterial hypertension (PAH) is rare in children and few data are available in a pediatric general population. This study aims to calculate the annual incidence and prevalence of PAH and to describe these children in a large US population of patients aged under 18 years. Using the US MarketScan claims database we identified 695 children with PAH in 2010-2013. We calculated annual incidence rates and prevalence overall, by age and PAH type (idiopathic and non-idiopathic) using Byar's method. We also described characteristics, co-morbidities, treatment patterns, and diagnostic procedures for these children...

PURPOSE OF REVIEW: Current recommendations for diagnosis and treatment of pulmonary arterial hypertension (PAH) during childhood are expert opinion based, because of lacking pediatric data. In recent years, however, important pediatric data have emerged on PAH. RECENT FINDINGS: PAH in children shows similarities as well as differences compared to adults. Neonates and children know specific clinical presentations and a hemodynamic profile that differs from adults with PAH...

BACKGROUND: Sickle cell disease (SCD) is a monogenic disease associated with multisystem morbidity. Vasculopathy caused by delicate imbalance between coagulation and endothelial systems plays a pivotal role in disease course. As Protein Z and Endothelin-1 genetic polymorphisms may increase the thrombotic risk, the aim of the current work was to verify the possible impact of Protein Z (PROZ G79A) and Endothelin-1 (EDN1 G5665T) polymorphisms on the clinic-laboratory features of the SCD in a cohort of Egyptian pediatric patients...

BACKGROUND: Congenital heart diseases in adults include malformations treated in childhood that decompensate secondarily and those asymptomatic at birth, appear later. This study aims to identify congenital heart diseases in adults in general cardiology department of Senegal and to assess clinical presentations, treatment and outcomes. METHODS: We conducted a cross-sectional and descriptive study based on the records of patients aged at least 16 years and followed for congenital heart disease in the cardiology department of the General Hospital of Grand-Yoff in Dakar between May 2003 and March 2015...

BACKGROUND: Invasive studies have shown that prevalence and severity of pulmonary hypertension (PH) in patients with sickle cell disease (SCD) tend to be overestimated if based exclusively on Doppler-derived tricuspid regurgitant velocity (TRV) as surrogate noninvasive marker with a cutoff ≥2.5 m/s. OBJECTIVES: We aimed to better define a subgroup of pediatric SCD patients who should be sent for invasive evaluation of pulmonary artery pressure (PAP) based on a modified echocardiographic PH screening protocol that implements evidence from Doppler-catheter comparative studies...

This study aims to review pediatric pulmonary hypertension (PH) by comparing the guidelines of the European Society of Cardiology (ESC)/European Respiratory Society (ERS), the American Heart Association (AHA)/American Thoracic Society (ATS), and the European Pediatric Pulmonary Vascular Disease Network (EPPVDN). All three sets of guidelines define PH as having a mean pulmonary artery pressure of ≥25 mmHg and accept the validity of the World Health Organization (WHO) classification system. Every child with a high index of suspicion for PH should undergo an initial work-up of chest X-rays, electrocardiography, and echocardiography...

Xia Li, Xue Wang, Shuguang Jin, Dongsheng Zhang, Yanuo Li
Flexible bronchoscopy is more and more used for diagnosis and management of various pulmonary diseases in pediatrics. As poor coordination of children, the procedure is usually performed under general anesthesia with spontaneous or controlled ventilation to increase children and bronchoscopists' safety and comfort. Previous studies have reported that dexmedetomidine (DEX) could be safely and effectively used for flexible bronchoscopy in both adulate and children. However, there is no trial to evaluate the dose-finding of safety and efficacy of dexmedetomidine-remifentanil (DEX-RF) in children undergoing flexible bronchoscopy...

BACKGROUND: Left ventricular dysfunction, mediated by ventricular interdependence, has been associated with negative outcomes in children with pulmonary arterial hypertension (PAH). Considering the dilation of the pulmonary arteries as a paramount sign of PAH, we hypothesized that the ascending aorta will present signs of apparent stiffness in children with PAH and that this effect may be because of mechanical interaction with the dilated main pulmonary artery (MPA). METHODS AND RESULTS: Forty-two children with PAH and 26 age- and size-matched controls underwent comprehensive cardiac magnetic resonance evaluation...

Obstructive sleep apnea (OSA) is a common pediatric breathing disorder, affecting 1-5% of all children. Pulmonary hypertension (PH), a severe complication of OSA, is associated with significant morbidity and mortality. Despite this important relationship between OSA and PH, there is sparse literature addressing this subject in children. This review will examine the putative relationship between OSA and PH, synthesize the available literature in children, and suggest a reasonable approach, despite limited data, for clinicians...

The practice of treating PAH patients with oral or intravenous sildenafil suffers from the limitations of short dosing intervals, peripheral vasodilation, unwanted side effects, and restricted use in pediatric patients. In this study, we sought to test the hypothesis that inhalable poly(lactic-co-glycolic acid) (PLGA) particles of sildenafil prolong the release of the drug, produce pulmonary specific vasodilation, reduce the systemic exposure of the drug, and may be used as an alternative to oral sildenafil in the treatment of PAH...

RATIONALE: The development of evidence-based treatment guidelines for pediatric pulmonary arterial hypertension (PAH) is hampered by lack of pediatric clinical trials. Trial design is hampered by lack of a feasible clinical endpoint in this population. OBJECTIVES: To evaluate the use of accelerometry for measuring physical activity (PA) in pediatric PAH and to investigate its correlation with clinical disease severity markers. METHODS: We included children from the Dutch National Network for Pediatric Pulmonary Hypertension...

Peak oxygen uptake (peak V ˙ O 2 ) measured by clinical exercise testing is the benchmark for aerobic fitness. Aerobic fitness, estimated from maximal treadmill exercise, is a predictor of mortality in adults. Peak V ˙ O 2 was shown to predict longevity in patients aged 7-35 years with cystic fibrosis over 25 years ago. A surge of exercise studies in young adults with congenital heart disease over the past decade has revealed significant prognostic information. Three years ago, the first clinical trial in children with pulmonary arterial hypertension used peak V ˙ O 2 as an endpoint that likewise delivered clinically relevant data...

Single living-donor lobar lung transplantation provides acceptable results for critically ill children; however, an additional lung transplantation may be required in the future as the recipient grows. We describe a case of successful lung retransplantation in a grown-up patient after single lobar lung transplantation in childhood. A 23-year-old man underwent bilateral cadaveric lung retransplantation for chronic lung allograft dysfunction 13 years after right single living-donor lobar transplantation for idiopathic pulmonary arterial hypertension performed at the age of 10 years...

Hemophagocytic lymphohistiocytosis (HLH) is an aggressive, life-threatening syndrome of excessive immune activation. Presentation is most common among the pediatric population, and cases in adults are rare. The number of nonhematologic presentations described in relation to HLH has been growing. We present a case involving a woman who developed HLH after autologous stem cell transplantation for mantle cell lymphoma. Months later, she received a diagnosis of pulmonary arterial hypertension (PAH) while undergoing treatment for her HLH...
