Alternative treatments in sickle cell disease

There is a growing desire for the development of alternative treatments and natural therapies for the treatment of sickle cell disease.

Submitted by (@sicklecellwarrior)

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

Details on the impact of addressing this CQ or CC :

Studies have indicated higher levels of fetal hemoglobin, even moderate levels, as being capable of reducing pain episodes. Development of therapies other than hydroxyurea, may be beneficial to individuals with SCD, specifically natural compounds as opposed to chemical based drugs. Additionally, it may be beneficial to the SCD survivors and the medical community to come up with biomedical alternatives to opiates and heavy narcotics used to induce relief and quiet the discomfort of the patient, even at the risk of addiction, resulting from prolonged usage (a life time).

Goal 4: Develop Workforce and Resources

Sickle cell education for healthcare providers

Although sickle cell was first described more than 100 years ago and more than 100,000 individuals in the US are living with sickle cell disease, healthcare providers still lack basic knowledge of the key components in providing care for individuals with sickle cell. This often leads to poor health outcomes including stigmatization of patients with sickle cell seeking care. Evidenced-based curriculum should be available ...more »

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.

Goal 2: Reduce Human Disease

How can we more safely deliver stem cells to Sickle Cell patients

Newer therapies using gene correction, rather than gene addition, are needed for sickle cell disease. Even with this potential advantage, there needs to be a way to safely deliver gene corrected HSC to the sickle cell patient. Chemotherapy is poorly tolerated, and often is the reason patients do not choose the BMT option.

Disease Severity Biomarkers for Sickle Cell Disease

Can we identify biomarkers that can predict sickle cell disease severity?

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 :

Identifying reliable biomarkers that can predict severity of sickle cell disease could help doctors and patients make better decisions about a wide range of clinical decisions, including weighing the risks vs. benefits of bone marrow transplantation, chemotherapeutic manipulation of Hb F level, and gene therapy, all of which have potentially life-threatening complications.

Feasibility and challenges of addressing this CQ or CC :

Scientific advances make it feasible to identify biomarkers of disease severity. However, identifying biomarkers with good sensitivity and specificity is likely to be a challenge.

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.

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?

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

Details on the impact of addressing this CQ or CC :

RLD is a major risk factor for death in adults, but there is minimal knowledge of the sequelae of contributing factors. There is no longitudinal study to demonstrate the risk factors, determinants, biological. A cross sectional study of adults could determine prevalence of lung function abnormalities, obstructive and restrictive, using standardized testing and understand the factors associated with the presence of these abnormalities. This study could be associated with a clinical trial of treatment of RLD with outcomes of symptom reduction as well as improvement of the restriction.
