Goal 2: Reduce Human Disease

How can we increase the pharmaceutical clinical research of targeted therapies in pediatric PAH patients, including encouraging

Clinical research, especially randomized pharmaceutical clinical trials, poses many unique challenges compared to research in adult subjects. In pulmonary arterial hypertension, a disease characterized by high blood pressure of the lungs with increased pulmonary vascular resistance leading to right ventricular failure, there are 12 FDA-approved PAH-targeted therapies for adults. None of these medications are currently... more »

Details on the impact of addressing this CQ or CC

Pulmonary arterial hypertension is a heterogeneous condition generally characterized by high blood pressure in the lungs and increased pulmonary vascular resistance that leads to right heart failure if left untreated. Though some causes of PAH are seen in both adult and pediatric populations, some etiologies are seen exclusively in pediatric populations, including persistent pulmonary hypertension of the newborn, bronchopulmonary dysplasia, lung hypoplasia, and alveolar capillary dysplasia. Despite these differences in disease etiology, and known physiologic differences in pediatric populations, inhaled nitric oxide (iNO) in the acute setting is the only approved medication for PAH treatment in children. A number of issues have decreased pediatric PAH pharmaceutical research, including protection of the pediatric population as vulnerable subjects, principle of scientific necessity, balance of risk and potential benefit, parental consent/child assent, and feasibility of pediatric clinical trial design and implementation. Encouraging clinical trials of existing adult medications and potentially emerging, novel agents specifically for pediatrics—either through direct sponsorship or regulatory incentives—would not only lead to better outcomes for pediatric PAH patients, but potentially to a better and more comprehensive characterization of the developing pulmonary vascular system and right ventricle.

Feasibility and challenges of addressing this CQ or CC

Several challenges exist for addressing this critical challenge. First, there are a number of differences between conducting clinical research in pediatric populations compared to adult populations. This not only includes the broad items referenced above, but items as noted by Rose and colleagues related to clinical trial design and analysis including (1) accepted age-matched normal ranges for laboratory values; (2) requirements for the validation of clinical endpoints for the assessment of efficacy and safety; and (3) standards for long-term safety monitoring and pharmacovigilance (Rose K, et al. NEJM 2005). Sponsorship of this type of clinical research is a second concern, which could either be mitigated by direct support from the National Institutes of Health of pediatric PAH clinical trials or in regulatory changes incentivizing pediatric clinical research in rare diseases.

Goal 2: Reduce Human Disease

Transfusion strategies in pediatric and neonatal populations

What are the optimal strategies for transfusion of blood products in pediatric and neonatal population?

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Compelling Question (CQ)

Details on the impact of addressing this CQ or CC

Blood is the most prescribed drug in the PICU, and 95% of all neonates are transfused during their stay in the NICU. Currently, there are no evidence-based guidelines for the optimal hemoglobin levels or platelet counts for these populations. There is a balance that must be achieved between hemostasis and thrombosis for this vulnerable population.

Feasibility and challenges of addressing this CQ or CC

Clinical trials have begun to assess the optimal hemoglobin levels in neonates, but there are no trial to asses the optimal platelet count. Neonatologists, pediatric intensivists, and transfusion medicine physicians are beginning to come together to work on solutions to these problems.

Understanding the Genetic & Epigenetic Basis of Congenital Heart Disease?

Over the last thirty years, our fundamental understanding of the genetics and pathogenesis of congenital heart disease has lagged the tremendous advances in the surgical and clinical care of infants with this group of disorders. We need to close this gap with investigation into the genetic basis of congenital heart malformations to develop new models of disease. The goall is translate an improved molecular genetic and... more »

Details on the impact of addressing this CQ or CC

Congenital heart disease (CHD) is the most common congenital malformation and the most common cause of mortality during the first year of life. Approximately 70% of cases occur sporadically without a strong family history or identifiable genetic syndrome, and the primary heritable basis of most non-syndromic CHD has yet to be identified. Studies of affected kindreds, syndromic disease, and more recently genome wide association studies (GWAS) have shed light on a handful of causal loci, while exome sequencing and studies of structural variation uncovering rare de novo variants in trios have yielded only an 8-10% rate of diagnosis in cohorts with CHD. Despite the application of contemporary techniques and study design to genetic discovery in CHD, the majority of the genetic risk for human cardiac malformations remains unexplained.

Feasibility and challenges of addressing this CQ or CC

One key challenge is that many of the stakeholders including those affected with congenital heart disease (children), along with the physicians make a diagnosis and referral (obstetricians, neonatologists, general pediatricians), are generally funded by other agencies (NICHD). Trans-agency collaboration and cooperation is necessary to improve the translational research structures necessary to improve disease.

Inflammation and outcomes following pediatric cardiac operations

What is the contribution of the inflammatory response to postoperative recovery following pediatric cardiac operations and what strategies can improve outcomes?

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Compelling Question (CQ)

Details on the impact of addressing this CQ or CC

Congenital heart disease is the most common cause of birth defects, with about 40,000 new cases born per year in the US. Affected individuals experience morbidity and mortality that generate health and economic consequences significantly out of proportion to their numbers. An estimated 10,000 of these patients will undergo cardiac surgery involving cardiopulmonary bypass (CPB). Furthermore, it is estimated that over 300,000 children in the US under age 21 have congenital cardiovascular disease and that 38% of these children will have had one or more surgical procedures. The use of CPB in neonates in particular has increased steadily over the past two decades. Further, neonates are generally sicker and consume more resources, including postoperative mechanical ventilation, ICU stay and hospital stay. Consequently, reducing the deleterious effects of CPB will have the largest impact in this group of patients.

Feasibility and challenges of addressing this CQ or CC

Research has begun to assess the inflammatory response to cardiopulmonary bypass in pediatrics. However, the magnitude and importance of its contribution to complicating postoperative recovery remains elusive. Clinical trials have begun to assess the efficacy of generalized anti-inflammatory therapies, typically steroids, with conflicting results. No therapy has been recognized as the standard of care. It’s critical that we improve our understanding of the molecular and cellular mechanisms of this inflammatory response and resulting derangements in vascular permeability and develop novel treatment strategies for infants and children undergoing cardiopulmonary bypass.

Additionally, hospitalizations related to pediatric hypertension have doubled over the past decade. These phenomena have clear and profound implications for the future cardiovascular health of the American population. The NHLBI has been instrumental in supporting studies in pediatric hypertension in the past, and we encourage a continued focus on pediatric populations for future hypertension research.
