Filter by:This study is design to assess the effects of an increase in nutritional intake on the bone mineral density of children with sickle cell disease, for 12 months.
Worldwide, an estimated 200,000 babies are born with Sickle Cell Anemia (SCA) annually. Affected children suffer chronic ill health with some having frequent hospitalization. The patients are also at a high risk of brain injury arising from small and large cerebral blood vessel damage in SCA, also called sickle cell vasculopathy (SCV). SCV is associated with the high risk of stroke. Such injury may manifest with neurological and cognitive impairment. An abnormal blood flow to the brain, as measured by a Doppler Ultrasound scan is a known risk factor for stroke. The hypothesis is that hydroxyurea therapy will prevent, stabilize or improve SCV and its effects. The study is an open label, single arm clinical trial to test the impact of hydroxyurea treatment in 270 children with SCA starting at ages 3-9 years. Following baseline assessments, all participants will begin hydroxyurea therapy starting at about 20mg/kg/day. Changes in the frequency and severity of each test (neurological and cognitive tests and cerebral blood flow velocity) will be compared with their baseline tests (prior to hydroxyurea) by repeating these tests at 18 and 36 months. In a randomly selected subset of 90 participants, an evaluation of the impact of hydroxyurea on structural brain vascular injury using magnetic resonance brain imaging (MRI) and magnetic vessel imaging ,also called angiography (MRA) at baseline and at 36 months. Lastly, an assessment of changes to biomarkers of anemia, inflammation and malnutrition from before and during hydroxyurea therapy and determine their relationship to the outcomes. The proposed intervention with hydroxyurea is the first Africa-based trial to broadly prevent or ameliorate manifestations of SCV.
The objective of this Expanded Access Protocol (EAP) is to provide voxelotor for the treatment of sickle cell disease (SCD): The study GBT440-041 is the EAP for pediatric patients aged 6 months to 11 years who have no alternative treatment options and are ineligible to participate in a clinical trial of voxelotor and the study C5341057 is the EAP for adults/adolescents 12 years of age and older for patients who cannot satisfactorily be treated with an authorized medicinal product
As safety information pertaining to the long-term use of HU remains incomplete in spite of the first safety study (ESCORT-HU), an extension of the latter is proposed. ESCORT-HU Extension study aims at evaluating the long-term safety of Siklos® focusing on some questions regarding its safety when used in current practice in adults and paediatric patients treated with Siklos® and followed for up to 5 years. The study will focus on the following concerns : occurrence and incidence of malignancies, leg ulcers, male fertility impairment and serious unexpected AEs causally related to Siklos®.
Sickle cell anemia (SCA) is one of the most neglected diseases worldwide, according to the World Health Organization. In the adult population with SCA, the systemic effects of the disease, such as respiratory and peripheral muscle dysfunction, cause a decrease in quality of life. As a consequence, there is a concern about functional rehabilitation, since the aging of this population is already a reality in our environment. Thus, the objective of this project is to evaluate the effects of functional rehabilitation on quality of life in adult patients over 18 years of SCA. In this longitudinal intervention study, patients will be submitted to a three-month rehabilitation program. Before and after the intervention, patients will be submitted to the following assessments: spirometry; quality of life questionnaire - Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36); functional scale of joint integrity - Lower Extremity Functional Scale (LEFS); fatigue assessment scale - Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F); physical activity assessment questionnaire - International Physical Activity Questionaire (IPAQ); peripheral muscle assessment (handgrip and isometric dynamometry of the quadriceps muscle); and 6-minute walk test (6MWT). The protocol will consist of warm-up and cool-down exercises, muscle strengthening and endurance exercises, aerobic training, balance training and proprioception. Thus, it is expected that patients with sickle cell anemia will benefit significantly, with a consequent improvement in musculoskeletal function, pain and health-related quality of life.
Vitamin D deficiency may be under-diagnosed in sickle cell disease French children. Therefore, the investigator need an epidemiologic study about the prevalence of vitamin D deficiency in this specific population. There are not specific guidelines neither testing nor treatment. The investigator propose to test vitamin D status in all children with sickle cell disease who are consulting their referring haematologist doctor or in the emergency ward.
The primary objective of this study is to better understand factors contributing to variations in hydroxyurea (HU) adherence behavior in adolescents and young adults (AYA) with sickle cell disease (SCD). To meet this objective, the researchers will conduct a prospective cohort study to determine the longitudinal relationship between HU adherence and health-related quality of life (HRQOL) overtime among AYA with SCD. The long-term goal of this research is to promote medication adherence behavior and improve health outcomes in AYA with SCD.
The primary objective of this study is to evaluate a potential behavioral intervention (MED-Go app). To meet this objective, the researchers will conduct a pilot randomized controlled trial to test the feasibility and acceptability of MED-Go app in adolescents and young adults (AYA) with sickle cell disease (SCD). The long-term goal of this research is to promote medication adherence behavior and improve health outcomes in AYA with SCD.
L-glutamine has been approved in the US to reduce the acute complications of sickle cell disease (SCD) in adult and pediatric patients 5 years of age and older. The purpose of this single-center, open-label, phase 4 study is to evaluate the pharmacokinetic characteristics and safety of L-glutamine in patients with SCD.
The overarching goal of this proposal is to identify modifiable behavioral strategies based on patient-reported outcomes (PROs) and health-related quality of life (HRQOL) that will improve hydroxyurea (HU) adherence among adolescents and young adults with sickle cell disease (SCD). In this proposed study, we intend to test the functionality of a PROs-toolbox feature, which will be integrated into our existing smartphone application platform (SCD-app), over a 24-week period in a cohort of SCD patients and their caregivers.
