Filter by:Sickle cell disease is the most common single-gene disease in the world. Its prevalence is increasing in France, with patients' life expectancy increasing into developed countries. It mainly affects populations originating from sub-Saharan Africa. Among the chronic bone complications associated with sickle cell disease, osteoporosis has previously been highlighted but remains a poorly known complication in this very particular context. A dedicated evaluation of osteoporosis and associated risk factors in sickle cell disease patients living in France may enable better bone management of these patients in the future, as this problem, specific to their disease, is likely to become more frequent as their life expectancy increases. This is a prospective interventional and monocentric study whose objective is to describe the prevalence of osteoporosis in black patients with sickle cell disease in France
The purpose of this study is to find out whether a web-based intervention using a mobile device is helpful for teens learning to care for and manage symptoms of sickle cell disease. The intervention lasts 12 weeks with a 3-month follow up period, and uses a smartphone or a tablet.
This is a phase 1, first-in-human, multi-center, open-label, single dose cohort study to evaluate the safety and tolerability, pharmacokinetics (PK), exploratory pharmacodynamics (PD), and biomarkers of target engagement of CSL889 following single intravenous (IV) doses in subjects with sickle cell disease (SCD). The study involves sequential dose escalation of cohorts with between-group assessments of key safety and PK variables.
This Phase 1 first-in-human, first-in-patient, single ascending dose and multiple dose study will be a randomized, double-blind, placebo-controlled investigation of the safety, tolerability, and pharmacokinetics of PF-07209326 in healthy participants and participants with sickle cell disease.
The purpose of this research is to study the causes of Sickle Cell kidney disease, as well as to collect and store samples and information about people with Sickle Cell Disease.
The purpose of this study is to assess the potential interventions of exercises in adults with sickle cell anemia (SCA) and cardiopulmonary disease; only including the more severe genotypes of sickle cell disease.
The Dissemination and Implementation of Stroke Prevention Looking at the Care Environment (DISPLACE) study is a multi-center, national, National Heart, Lung and Blood Institute (NHLBI)-funded grant to look at the real-world implementation of stroke prevention guidelines (STOP Protocol) in which transcranial Doppler (TCD), a measure of cerebral blood vessel velocity, is used to screen for stroke risk in children ages 2-16 with sickle cell anemia (SCA). Part 3 of the DISPLACE study is an implementation clinical trial designed to test novel implementation strategies with the goal of improving adherence and implementation of stroke screening. 16 of the lowest scoring implementation rates from DISPLACE Part 1 will participate in DISPLACE Part 3. All original 28 sites from DISPLACE Parts 1 and 2 will receive a patient and provider educational intervention including a re-branding of the TCD as "Sickle Stroke Screen" with a new infographic and educational materials. The 16 sites with moving to Part 3 will be provided a Provider reminder strategy, which is a web based application designed to remind providers of when patients are due for their Sickle Stroke Screen. These 16 sites will be randomized and 8 will be given an additional Patient Communication Strategy. These sites will have a single designed coordinator with whom patients will communicate with about scheduling, rescheduling, and any other questions regarding their Sickle Stroke Screen. Upon completion, data will be analyzed to compare those who have had TCD screenings done appropriately and those who did not as well as the overall effect of the multi level interventions on the changes in TCD rates.
This is an open-label study to understand the safety and tolerability of AXA4010, a novel composition of amino acids in adult and adolescent subjects with sickle cell disease over 12 weeks. The study also assesses the effects of this amino acid composition on the structure and function of the vascular system. Physiological effects on structure and function will be assessed by Magnetic Resonance Imaging (MRI) to assess blood flow in the brain and kidneys and the 6-Minute walk with pulse oximetry. Changes in blood biomarkers of inflammation will also be assessed.
Aim: Sickle cell disease (SCD) is a hereditary disease. Approximately 5% of the world's population carries trait genes for haemoglobin disorders, mainly, sickle-cell disease and thalassaemia. The incidence of sickle cell disease varies according to different geographical locations. Persons with SCD experience both acute and chronic pain. it is important that nonpharmacological therapies be investigated and used as complements to pharmacological therapies to address and treat both acute and chronic pain for those with SCD. An educational program involving parents with children with SCD can help parents use nonpharmacological methods for their children in reducing pain. The training program allows parents to develop their knowledge of the SCD and the importance of non-pharmacological methods, and may provide parents with the opportunity to develop preventive attitudes towards reducing pain crises. The research has two purposes. The first is to identify the non-pharmacological approaches that parents use to help their children with sickle cell disease in Turkey, Chad. Second, to determine the effectiveness of non-pharmacological approaches given to parents in Turkey, Chad. Method: This study is an experimental research method using a quasi‐experimental design. This study used a pretest and posttest, with a design that is used is the two group pretest-posttest design. The study was conducted on the parents of children with sickle cell disease diagnosed and followed up in the Pediatric Hematology Oncology polyclinics of two hospitals in Chad in Central Africa between September 2015 and February 2016. The study found in April 2016 and July 2016 between Turkey's southern Antalya and Mersin two university hospital outpatient Children's pediatric hematology oncology has made clinic on sickle cell disease diagnosed and monitored the children's parents. The parents were selected using eligibility criteria and the study was performed in three steps (Pre-intervention testing session, education session, and post-intervention testing session). In the first step, "Information Form", "Parents' Experience of Nonpharmacological Methods Questionnaire", and "Nonpharmacological Approaches Used by Parents for Their Children and Knowledge of Parents about Nonpharmacological Approaches Questionnaire" questionnaires were applied to parents. In the second step an individual education was conducted by the researcher using the education book. In the third step, the questionnaire were reapplied after 3 weeks.
This project proposes to develop, test and evaluate targeted interventions to improve clinical provider prescribing of and patient adherence to hydroxyurea (HU). Using a stepped-wedge design, The investigators will test two innovative interventions utilizing mobile health to address both patients' and providers' needs: 1) an mHealth application for patients (InCharge Health app) that includes multi-component features to address the memory, motivation, and knowledge barriers to hydroxyurea use, and 2) an mHealth toolbox application for providers (HU Toolbox app) that addresses clinical knowledge barriers in prescribing and monitoring hydroxyurea use. These two interventions will be tested through the following aims: Aim 1. Improve Patient Adherence to Hydroxyurea: Addressing Memory, Motivation, and Knowledge Barriers to Hydroxyurea Use. Primary hypothesis: The investigators hypothesize that among adolescents and adults with SCD, the adherence to hydroxyurea, as measured by percentage of days covered (PDC), will increase by at least 20% at 24 weeks after receiving the InCharge Health app, compared to their hydroxyurea adherence at baseline. Sub-aim 1.a. To examine and assess both patient engagement and behaviors related to use of the InCharge Health app, the investigators will evaluate consistent use of the app among enrolled patients, patient satisfaction, and continued use of the app beyond the study period. Sub-Aim 1.b. To examine the clinical influence of the use of the InCharge Health app on PDC, patients' clinical outcomes, perceived health literacy, health related quality of life, and perceived self-efficacy between baseline and 24 weeks. Aim 2. Improve Provider Hydroxyurea Awareness, Prescribing and Monitoring Behaviors. Sub-Aim 2.a. To examine and assess provider engagement and behaviors related to use of the HU Toolbox, the investigators will evaluate consistent use of the app among enrolled providers, providers' satisfaction, and continued use of the app beyond the study period. Sub-Aim 2.b. To assess the combined effects of the patient and provider mHealth interventions on hydroxyurea and health care utilization, the investigators will examine if the changes in hydroxyurea adherence are enhanced by the use of both provider and patient interventions compared to those not exposed to one or both interventions. Aim 3. Identify and Evaluate the Barriers and Facilitators to the use of mHealth Interventions.
