Impact of lung remodeling on congestive heart failure progression

End stage congestive heart failure (CHF) causes intensive lung remodeling beyond the type-2 pulmonary hypertension. CHF induced lung remodeling includes profound lung fibrosis, lung vascular remodeling and lung inflammation. Understanding CHF-induced lung remodeling is also critical to understand the right ventricular failure. However, this area is largely unstudied. Regulating CHF-induced lung remodeling and the underlying ...more »

Targeting Inflammation in Venous Thromboembolism

What is the role of inflamation in venous thromboembolism, both DVT and PE. If the inflammatory response can be controlled, then clot formation should be able to be decreased or eliminated without bleeding potential. The effect of the inflammatory response on the wall of the veins, both in the legs and the lungs, leads to changes that result in pain and swelling (legs) and pulmonary artery hypertension (lungs). Inhibiting ...more »

I would suggest that studies addressing this issue using new targeted anti-inflammatory medications be supported in both large animal models (close to human) and in clinical translational studies.

Feasibility and challenges of addressing this CQ or CC :

This is feasible and doable - there is data suggesting that inflamatory inhibition with agents that target the selectins (for example) lead to a lessening of thrombosis, and decreases in vein wall damage, all without bleeding potential. These conepts in animals need to be evaluated in clinical studies. Additionally, there are other off-shoots such as studies with biomarkers of inflammation and how they can be helpful in making the diagnosis and predicting the response to therapies.

Details on the impact of addressing this CQ or CC :

Pain is the most common clinical manifestation of sickle cell disease (SCD) and accounts for a large proportion of emergency department visits and hospitalizations. Due to its impact on the patients’ quality of life, there is a need for more basic and clinical research studies focused on understanding the mechanisms of different pain syndromes as well as the role of neurotransmitters and inflammation in acute and chronic SCD pain. Also, comparative effectiveness studies in the management of chronic pain will be crucial in helping to improve the patients’ overall quality of life.

Small studies suggest a therapeutic effect of anti-inflammatory medication in childhood OSAS. This may be especially useful in children with residual OSAS following adenotonsillectomy (as CPAP adherence tends to be low) or children who are poor candidates for surgery. Current studies have been limited to children with extremely mild OSAS, have not determined whether atopy plays a role in the response to therapy, and have been limited to very short-term trials.

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?

Submitted by (@grahamem)

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.

What is the role of chronic inflammation in lung complications in the HAART era?

With the advent of HAART HIV-infected subjects are living longer. Lung infectious complications so common in the early stages of the HIV epidemic have been replaced by those associated with chronic inflammation (COPD, pulmonary hypertension, lung cancer). Furthermore, this chronic inflammation is likely contributing to premature vascular complications (i.e coronary disease) seen in this population. All of these complications ...more »

Details on the impact of addressing this CQ or CC :

Addressing the role of chronic inflammation in chronic lung and vascular diseases will impact both the HIV population and our growing U.S. aging population. Approaches to the question could include:

1.. Causes of chronic inflammation

- Antiretroviral drugs, persistent HIV, persistence of other viruses, exogenous retroviral elements, exosomes, other epidemiologic exposures

2. Downstream mechanistic effects of chronic inflammation

- Alterations in gene regulation, alterations in oxidative stress, direct tissue damage

3. Clinical outcomes of chronic inflammation

- Lung – COPD, pulmonary HTN, cancer, interstitial lung disease, asthma.

- Vascular compartment - premature coronary and vascular disease

- Does HIV-infection itself require alterations in treatment modalities for lung disease

- Does HIV infection itself alter the outcome of chronic lung disease?

4. Therapeutic options

- Directed against the cause – i.e. antivirals.

- Immune specific targets against inflammatory mediators

Feasibility and challenges of addressing this CQ or CC :

The critical challenge for this question lies in the fact that complications caused by chronic inflammation such as COPD and coronary disease will by definition take years to develop. Intervention trials will take even longer. This is not like the early HIV epidemic, where complications were primarily infectious and could be seen and addressed quickly. Because of this chronic nature, it will necessary to try and establish cohorts with long term follow-up. Furthermore, it will be critical to have well defined appropriate HIV-uninfected cohorts to compare the HIV-infected population to.

The Human Virome and Host Interactions in Heart, Lung, and Blood

What are the unknown elements of the human virome, and what host-virome interactions affect the heart, lung, and blood health and diseases? A major challenge has been the need for in vitro culture systems and animal models for studying the virome, which is a significant limitation that has forced current studies of the virome to be mostly descriptive.

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

Details on the impact of addressing this CQ or CC :

• The virome contains the most abundant and fastest mutating genetic elements on Earth. The human virome is constituted of viruses that infect host cells, virus-derived elements in our chromosomes, and viruses that infect the broad array of other types of organisms that inhabit us. The virome may influence the host in profound ways independent of classical viral disease. The immune system is continuously stimulated by chronic systemic viruses and this aspect of host-microbiome interactions appears specific to the virome. The virome is considered one of the drivers of idiopathic systemic inflammation that has been linked to many of the most severe public health threats, including cardiovascular diseases. Disruptions in immunity by immunosuppressing events can undoubtedly alter the interactions of the virome with the host. However, little research has been done in all of these aspects other than limited descriptive studies to identify the presence or composition of the human virome. The NHLBI Microbiome Working Group in June 2014 clearly identified under-representation of studies of the human virome. Identification and characterization of unknown viral elements of the human virome and research on the interactions with the host will allow exploration of their impact on heart, lung and blood health and diseases, including impact in the presence of immunosuppression with the host such as in AIDS or HIV infection.

Feasibility and challenges of addressing this CQ or CC :

This initiative is feasible because of new technologies that have been developed recently such as the deep sequencing techniques. The initiative is also timely in that research supported by the NIH Human Microbiome Program and other programs has allowed us to better understand microbiome, especially bacteria in and on humans, and we began to realize the magnitude of the virome. This initiative will attract more investigators to not only identify more elements of the virome but more importantly to understand the roles of the human virome in heart, lung and blood health and diseases, and eventually to help develop diagnostic and intervention strategies.
