Filter by:The primary objective of the 1701-202 STRONG SCD study is to evaluate the safety and tolerability of different dose levels of IW-1701 compared with placebo when administered daily for approximately 12 weeks to patients with stable SCD. Exploratory objectives include evaluation of pharmacokinetic (PK) as well as evaluation of the effect of IW-1701 on symptoms of SCD, health-related quality of life, and biomarkers of pharmacodynamic (PD) activity.
This project will improve the efficiency and quality of healthcare for persons with sickle cell disease, an under-served and at risk population by implementing a co-management model of care. Many patients with sickle cell disease (SCD) receive care primarily from specialty physicians and emergency departments (ED), thus resulting in a lack of primary care and a high number of ED visits and hospitalizations. The goal is to improve PCP and SCD specialist co-management. The overall purpose of this dissemination project is to evaluate utilization data, as well as patient and provider reported outcomes associated with the dissemination of a toolbox of decision support tools to PCP's and ED providers across NC and SC.
Secretory phosholipases A2 (sPLA2) are significantly elevated in the plasma of sickle cell disease patients with acute chest syndrome (ACS), and similar enzymes have been measured in exhaled breath condensate (EBC), which is collected easily and non-invasively. The investigators hypothesize that sPLA2 will be measurable in EBC samples from sickle cell patients with acute chest syndrome.
Background : Sickle cell patients have profound remodeling of their muscle microcirculation networks with signs of amyotrophy. However, the consequences of these muscle alterations on the functional status of muscles are unknown. In addition, whether the poor physical fitness of sickle cell patients can be attributed, at least partly, to an hypothetical muscle dysfunction has never been tested. Purpose : this study will compare the muscle function of legs between sickle cell patients (SS and SC genotypes) and healthy individuals (AA genotype) before, during and after a short localized muscle endurance exercise. Abstract : Very recently, a study reported large differences between the muscle microcirculation networks of sickle cell patients compared to healthy individuals with decreased capillary density and higher proportion of large capillaries in the former population. In addition, the same study showed signs of amyotrophy in sickle cell patients. However, the muscle function of sickle cell patients has not been investigated and one may suggest that muscle dysfunction could participate in the decrease of physical fitness, in association with the hematological and hemorheological disorders, already reported in this population. The hypothesis is that muscle fatigue during a short localized muscle endurance exercise should be higher in sickle cell patients compared to healthy individuals, due to a greater recruitment of glycolytic fibers and a faster decrease of muscle oxygenation during exercise.
Evaluation of knowledge about contraception in sickle cell adolescents.
The purpose of this study is to investigate the effects of the BEATS music therapy program on the self-efficacy, trust, knowledge, and adherence of young adult patients with SCD. Primary Hypotheses: Compared to baseline, young adult patients with SCD who receive the music therapy interventions will report: Higher sickle cell self-efficacy as measured by the Sickle Cell Self Efficacy Scale (SCSES), Higher trust in health care providers as measured by the Wake Forest Trust in the Medical Profession Scale, and Higher SCD knowledge as measured by the Seidman Sickle Cell Knowledge Quiz. Secondary Hypotheses Compared to the one year prior to the study period, young adults with SCD who receive the music therapy interventions will have a higher rate of adherence to clinic appointments during the one-year study period. Additional Questions Do music therapy interventions influence the rate of hospital utilization as measured by ED visits, Acute Care Clinic (ACC) visits, and admissions during the study period compared to the previous year? Do music therapy interventions influence adherence to hydroxyurea therapy for patients receiving hydroxyurea as measured by change in mean corpuscular volume (MCV) during the study period? Do music therapy interventions influence adherence to iron chelation therapy for patients receiving iron chelation therapy as measured by ferritin count during the study period? Does the schedule of music therapy interventions in this study improve outcomes more significantly than the schedule of music therapy interventions from [IRB# 03-15-30]?
The constitution of blood relies upon hematopoietic stem cells (HSCs), which stay in the bone marrow and differentiate to all lineages of peripheral blood cells. HSC transplantation is the only curative option currently available for sickle cell disease (SCD) patients either via allogeneic HSC transplantation or HSC-targeted gene therapy. Granulocyte-colony stimulating factor (G-CSF)- mobilized HSCs are frequently utilized in the adult setting of HSC transplantation because of the faster hematologic recovery as compared to bone marrow. As an autologous HSC source for gene therapy, bone marrow harvest has been generally employed since G-CSF has been prohibitive in SCD patients due to granulocyte stimulation and the associated reports of vaso-occlusive crises, multi-organ failure, and death. However, when bone marrow harvest is used, the amounts of collected cells are limited and anesthesia is required. In order to obtain HSCs in large numbers without anesthesia, patients will undergo mobilization followed by large volume apheresis. Plerixafor is an alternative treatment for mobilization without direct stimulation to granulocytes, and it is theoretically applicable for SCD patients. The primary endpoint of this study is to obtain sufficient amounts of HSCs collected from the peripheral blood in SCD patients after plerixafor mobilization with an acceptable safety profile. The harvested products will be stored as backup for patients undergoing gene therapy as well as allogeneic HSC transplantation.
The purpose of this study is to gather decision making needs information from caregivers and patients with sickle cell disease (SCD) in order to develop a web-based decision aid tool. Study subjects will participate in interviews defining treatment decision making needs during which investigators will ask information about their SCD. Notes taken from these interviews will allow the research team to better understand current practice related to clinical practice and allow for better refinement of the decision aid tool. An additional group of participants will be asked to review the web-based Sickle Cell Decision Aid. Participants will be asked to describe thoughts about the site, including but not limited to ease of navigation, content and construction. This study will provide information for the conduct of a randomized controlled trial for the use of a web based decision aid to give patients with sickle cell disease and parent/legal guardian of children with sickle cell disease accurate information about risks and benefits of therapies and enable them to make decisions based on their individual values and preferences.
The project will test a tailored web and smartphone-based application (iCanCope with SCD) to improve pain self-management and functioning in youth (aged 12-18) with sickle cell disease. The program will include goal setting, peer-based social support, and pain self-management training. The investigators will determine initial program effectiveness through a pilot three-site randomized controlled trial in 160 youth randomized to treatment compared to attention control.
Background: Sickle cell disease (SCD) is caused by a genetic defect that affects how hemoglobin is made. Due to this, people with SCD have abnormally-shaped red blood cells, which can result in poor oxygen transport in the body and increase risk of blood clots. CRISPR Cas9 is a new tool which allows scientists to snip and edit genes in a way that is faster, cheaper, and more precise than other gene-editing tools. Recently, research has been done using CRISPR Cas9 to correct the sickle cell gene in animal models and human cells. Researchers want to understand the views of those with SCD, parents of people with SCD, and the providers of these patients regarding use of CRISPR Cas9 in clinical trials and treatment. Objectives: To study the attitudes, beliefs, and opinions of those with SCD, parents of those with SCD, and providers on the use of CRISPR Cas9 gene-editing. An additional purpose of this study is to assess the utility of an educational tool for improving understanding of CRISPR Cas9. Eligibility: People ages 18 and older who speak English and either have SCD, are a parent of someone with SCD, or are a physician for people with SCD. Design: Participants will be screened via phone. Those with SCD will be screened with data from their SCD genotype. Participation lasts about 2 hours. Participants will fill out three surveys. Participants will watch a video about CRISPR Cas9. Participants will engage in a focus group session. This will be audiotaped and analyzed. The data from the survey questions and focus groups may be used for future research. However, all personally identifiable information will be removed before data is shared. Participants data will be identified with a code number instead of their name. Participants may be invited to join future studies of SCD.
