mAnaging siCkle CELl disEase Through incReased AdopTion of hydroxyurEa in Nigeria

ACCELERATE
Start date: August 2024
Phase: N/A
Study type: Interventional

Large knowledge gaps remain regarding strategies to promote the adoption of hydroxyurea (HU), particularly in sub-Saharan African countries including Nigeria, where more than 75% of annual sickle cell anemia births occur. The vast majority of people with SCD in Africa do not receive evidenced-based health care (e.g., newborn screening, health education, prophylaxis for infection, optimal nutrition and hydration, blood transfusion, transcranial Doppler screening, and HU therapy), despite its effectiveness in reducing SCD-related adverse outcomes and mortality. The use of HU in SSA is <1% among SCD patients. The investigators' preliminary findings indicate that provider-level barriers are significant and must be addressed to improve HU adoption. To address HU adoption, the investigators will use the NIH-funded study (e.g., Realizing Effectiveness Across Continents with Hydroxyurea (REACH) Clinical Trial (NCT01966731)) that developed an evidence-informed, clinical, practical, and easy-to-follow algorithm to 1) Screen patients for sickle cell disease (SCD), 2) Initiate HU treatment, and 3) Maintain HU dosage over time (SIM) for the improved management of SCD as our intervention. The Nigerian government released guidelines supporting the SIM intervention for HU adoption for improved SCD management, and HU is on the list of essential medicines for Nigeria. The investigators' implementation strategy for improving SCD management in Nigeria uses a practical and replicable evidence-based task-sharing strategy, TAsk-Strengthening Strategy for Hemoglobinopathies (TASSH), adopted from the TAsk-Strengthening Strategy for Hypertension control (TASSH) trials in Ghana and Nigeria containing the essential components of i) Training healthcare workers/providers to be more patient-centered in clinical consultations, ii) Clinical reminders, and iii) Practice facilitation (TCP) known as (TASSH TCP) for SCD management. Using a sequential exploratory mixed-methods study design, the investigators will conduct this study using the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework in four sequential phases to assess the effectiveness of SIM adoption by providers in the context of the TASSH TCP implementation strategy in Nigeria.

Determination of Red Cell Survival in Sickle Cell Disease and Other Hemoglobinopathies Using Biotin Labeling

Start date: March 31, 2024
Phase: Early Phase 1
Study type: Interventional

Background: Sickle cell disease (SCD) is an inherited disorder of the blood. SCD causes red blood cells (RBCs) to die early. This can lead to a shortage of healthy cells. SCD and other blood disorders can be managed with drugs or cured with a bone marrow transplant. Researchers want to know how long RBCs survive in people with SCD and other blood disorders before and after treatment compared to those who had a bone marrow transplant. Objective: To learn how long RBCs survive in the body in people with SCD and other blood disorders compared to those whose disease was cured with a bone marrow transplant. Eligibility: People aged 18 years or older with SCD or another inherited blood disorder. People whose SCD or blood disorder was cured with a bone marrow transplant are also needed. Design: Participants will be screened. They will have a physical exam with blood and urine tests. Participants will have about 7 tablespoons of blood drawn. In the lab, this blood will be mixed with a vitamin called biotin. Biotin sticks to the outside of RBCs. This process is called "biotin labeling of RBCs." The next day, the participant s own biotin-labeled RBCs will be returned to their bloodstream. Participants will return regularly to have smaller blood samples (about 2 teaspoons) drawn. These samples will be tested to detect the percentage of cells that have biotin labels. These visits may be every 2 weeks, 4 weeks, or some other interval. Participants will continue this schedule for up to 20 weeks or until biotin can no longer be detected....

Uganda Sickle Surveillance Study (US-3)

Start date: September 7, 2013
Phase:
Study type: Observational [Patient Registry]

It is estimated that over 250,000 babies are born with sickle cell disease (SCD) annually in sub-Saharan Africa, and only 10% - 50% of them survive beyond five years of age. Data describing the magnitude of the sickle cell problem are lacking in most African countries. The available data on prevalence were mainly from older studies and small numbers of hospitalized patients. In Uganda, approximately 25,000 children are born with SCD but 70-80% die before their 5th birthday. Lehmann and Raper found 'sicklaemia' prevalence of 0.8% and 45% in the Sebei and Bambaa ethnic groups, respectively. A recent study found a SCT and SCD prevalence of 3% - 19% and 0% - 3%, respectively but this study addressed only 5 of Uganda's 111 districts and used a small convenience sample of children aged 6 - 60 months. The objective of this study is to determine the prevalence and map out the burden of SCT and SCD in Uganda.

NCT ID: NCT06274203 Completed - Sickle Cell Disease Clinical Trials

High Dose Vitamin D Supplementation in Children With Sickle Cell Disease

Start date: May 3, 2023
Phase: N/A
Study type: Interventional

Suboptimal vitamin D status is well reported in sickle cell disease (SCD) patients and associated with a negative impact on health-related quality of life (HRQL). The investigators enrolled 42 SCD patients and 42 healthy controls, subjects within each group received monthly oral vitamin D3 dose according to the baseline status of vitamin D as follows: sufficient: 100,000 IU, insufficient: 150,000 IU, and deficient: 200,000 IU. The investigators assessed safety and efficacy on normalization of vitamin D level, bone mineral density (BMD), hand grip strength (HGS), and HRQL.

NCT ID: NCT06264700 Not yet recruiting - Sickle Cell Disease Clinical Trials

Applying Directly Observed Therapy to Hydroxyurea to Realize Effectiveness

ADHERE
Start date: March 2024
Phase: N/A
Study type: Interventional

This study is for caregivers of young children with sickle cell disease and adolescents with sickle cell disease who are currently prescribed hydroxyurea and are receiving care at one of the study sites. The study will assess retention and engagement during a pilot randomized control trial comparing video directly observed therapy (VDOT) to attention control. We also hope to understand more about patient and family preferences longer-term adherence monitoring and intervention. Participants will use an electronic adherence monitor (provided by the study team) to measure how often they are taking their hydroxyurea. Participants will also be asked to complete questionnaires throughout the study period to provide information about their expectations for, experience with, and satisfaction with the study materials.
