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

Details on the impact of addressing this CQ or CC :

Unless an individual is a candidate for transplantation, sickle cell will be a lifelong challenge. Much effort has been focused in the pediatric area and on physical aspects of the disease. However, adult care and mental/psycho-social health have not been adequately addressed. A holistic approach across the lifespan would fill these gaps and perhaps lead to better health outcomes and addresses NHLBI's goal of reducing the burden of human disease.

Pulmonary Complications of Sickle Cell Disease - Contribution of Airways Disease

What is the contribution of airways disease to acute and chronic pulmonary distress?

Submitted by (@nhlbiforumadministrator)

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

Details on the impact of addressing this CQ or CC :

What is known about this topic:

 

1) Pulmonary function testing is abnormal in 80-90% of kids and 90% of adults with SCD.

 

2) SCD kids with asthma have a higher frequency of ACS and those with a history of ACS have a higher prevalence of asthma.

 

3) An elevated TRV in SCD kids and adolescents may not predict mortality but does predict reduced exercise capacity at 22 months which may be irrespective of pulmonary hypertension

 

4) Dyspnea is extremely common in adults with SCD; 50% of HbSS and 40% of HbSC adults report at least mild dyspnea on exertion. The mechanisms responsible for this are unknown.

 

5) Bronchodilators are often used to treat patients with ACS, yet their benefit is unclear.

 

6) Systemic steroids will increase the rate of rebound pain if used during a vasoocclusive crisis.

 

7) Asthma in SCD is frequently under-treated because of fears associated with systemic and even inhaled corticosteroid use.

Feasibility and challenges of addressing this CQ or CC :

Areas of Controversy:

1) Is there an inter-relationship between airway and vascular disease in SCD?

 

2) Are systemic corticosteroids safe in SCD? Are they indicated in treatment of ACS? Are they indicated for treatment of asthma exacerbations?

 

3) Are inhaled corticosteroids useful in treating or preventing ACS?

 

4) What are the mechanisms responsible for the decline in exercise capacity observed as SCD patients go from late adolescence to early adulthood?

 

5) Will more aggressive treatment of asthma prevent this decline?

 

6) What role does nocturnal hypoxemia and OSA play in disease modulation of SCD?

 

7) What are the mechanisms of the restrictive physiology observed by PFTs primarily in adults?

Goal 2: Reduce Human Disease

The treatment of asthma in patients with SCD prevents the development of ACS and VOS.

Does the aggressive treatment of asthma prevent the developement of acute chest syndrome (ACS) and vaso-occlusive syndrome (VOS) in patients with sickle cell disease (SCD)?

Submitted by (@nhlbiforumadministrator)

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

Details on the impact of addressing this CQ or CC :

Improvement of health for persons with SCD.

Decreased hospitalizations and use of health resources.

Better understanding of the role of bronchospastic/inflammatory airway disease and hypoxemia as causes of acute chest syndrome and VOC.

Feasibility and challenges of addressing this CQ or CC :

Feasible but stumbling block could be enrollment of patients since many patients with SCD are not seen by asthma specialists. Study could be a multicenter study with two hospitals in one major city and in one center, patients with SCD receive usual care and at another center they receive aggressive treatment and monitoring of their lung disease.

Goal 3: Advance Translational Research

Genome Editing and Gene Therapy

There is a critical need for the establishment of strategies that will determine the efficacy, safety, and toxicity of genome editing techniques specifically in hematologic diseases.

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

Details on the impact of addressing this CQ or CC :

Inherited monogenic hematologic diseases such as hemophilia, beta-thalassemia and sickle cell disease are prime targets for future application of genome editing technology. However, studies are still needed to advance our understanding of the biology of genome editing as well as determine which other disorders are amenable to genome editing correction. Emphasis on preclinical research that focuses on determining the accuracy, safety and efficiency of this technology in order to help minimize off-target mutations and reduce toxicity, is essential for effective translation of this technology into the clinic. Once preclinical efficacy is established, support will be needed for clinical vector production, toxicity testing of the vectors/reagents used, and the performance of clinical trials. The gene correction strategies developed for inherited disorders will also be attractive for other hematologic diseases, and autoimmune disorders like lupus, rheumatoid arthritis, and type I diabetes). There is also a critical need for supporting preclinical validation studies, scale-up and GMP cell manufacturing, all of which could be shared infrastructures across multiple diseases in the NHLBI portfolio.

Details on the impact of addressing this CQ or CC :

Multiple Single Nucleotide Polymorphisms (SNPs) have previously been identified in the mu opioid receptor and it is estimated that millions might exist throughout the genome. Drastic phenotypic variability exists among patients in the sickle cell community. Do SNPs account for any of this variability and can this information be used to more effectively treat sickle cell disease.

Mental health and wellness in sickle cell disease

A growing concern among the sickle cell community surrounds the lack of mental health and wellness services. Many in the community deal with anxiety and depression. It is well known how intricately connected mental and physical health are. So if we know that stress can trigger a psychological crisis which in turn triggers a physical pain crisis, why do we not automatically include mental health services within patient ...more »

Identification and validation of surrogate endpoints for long-term morbidity in Sickle Cell Disease

Research in sickle cell disease (SCD) has mostly focused on preventing or treating acute medical events, such as vaso-occlusive pain, acute chest syndrome, and, in pediatric patients, acute strokes. Chronic SCD complications such as chronic kidney disease or pulmonary hypertension, develop over decades, thus are poor choices for clinical trial endpoints. There is a great need to develop surrogate endpoints that predict ...more »

What is the place of curative therapies in the management of Sickle Cell Disease

Advances in the care of pediatric patients with sickle cell disease ( SCD) have resulted in improved survival to adulthood.However, adulthood is marked by rapid disease progression, impaired quality of life and premature mortality.

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

Details on the impact of addressing this CQ or CC :

To overcome this obstacle to progress in the field, we propose the creation of the funding mechanisms for a multicenter clinical trial consortium which would bring together investigators in field and facilitate study the outcomes of CT for patients with different types of donors and stem cell sources and compare them to outcomes in phenotypically matched controls receiving best available standard of care.Answering the compelling question about the role of CT in the management of SCD has the potential to have a catalytic effect in progress in this field. Patients are are then more likely to receive CT or standard of care at the appropriate time and in the manner in which they are most likely to have a positive outcome. This has the potential to reduce morbidity and premature mortality and in the long run, to decrease the burden of the disease on the healthcare system. The advent of clinical trials of gene therapies for SCD offers the prospect of even greater applicability of curative therapies. Thus, a consortium developed to answer this CQ would serve as a crucial vehicle for providing access to a greater proportion of patient to these personalized curative therapies . Such studies would also be powered to answer the question about who should receive the curative therapy, when they should receive it, and how it would impact their SCD related complications, late effects, survival and quality of life and help families make informed choice appropriate for their situation.

Feasibility and challenges of addressing this CQ or CC :

The increasing applicability and acceptability of HCT for SCD is evidenced by the doubling in the number of such procedures reported to CIBMTR in the decade starting 2001. Refinements in conditioning regimen and supportive care continue to improve outcomes in children and now in adults with SCD undergoing HCT from HLA matched related donors. Recently, HCT from unrelated donors and from haplo-identical donors have further increased the applicability of HCT. Opening of gene therapy trials has further raised the prospect of cure for a greater proportion of patients. These developments are evidence of the feasibility of recruitment to large multi-center comparative trials of SCD and standard of care. Recently, there has been increasing collaboration among investigators in the field with informal consortia being developed by investigators coming together to study HCT for children, adults or HCT from haplo-identical donors. These groups are also increasingly working with SCD hematologists, families and other stakeholders. There is also increasing cross-cutting collaborations with other medical specialists and behavioral and translational scientists Thus, the convergence of several factors described above suggests that the time is fortuitous for a major initiative from the NHLBI to bring investigators together and create the infrastructure that will enable these investigators to seek definitive answers to the challenging question “What is the place of curative therapy in SCD?”.
