Filter by:The objective of this study is to determine the seroprevalence of severe acute respiratory syndrome-CoV-2 in unvaccinated sickle cell patients living in an area with high viral circulation and at risk of high viral transmission, after the 4th epidemic wave of COVID-19 in Ile-de -France, over a period of 3 months (for example, last quarter of 2021).
This is an open label, non-randomized, 2-center, phase 1/2 trial of a single infusion of sickle allele modified cluster of differentiation (CD34+) hematopoietic stem progenitor cells (HSPCs) in subjects with in subjects ≥12 years old to 35 years old severe Sickle Cell Disease (SCD). The study will evaluate the hematopoietic stem cell transplantation (HSCT) using CRISPR/Cas9 edited red blood cells (known as CRISPR_SCD001 Drug Product).
Sickle cell crisis continues to be a frequent presentation to emergency departments. Patients presenting will often require immediate treatment for their pain and often times this will include opioids. The opioid epidemic has cost thousands of lives; and continues to be a significant problem posing several challenges when treating patients presenting with sickle cell disease. Primarily, opioids remain the mainstay of treatment for these patients and the push to address the opioid crisis may present challenges for adequate opioid administration in patients suffering from a sickle cell crisis while hospitals find ways to curb the opioid crisis overall. Opioid treatment for patients in acute vaso-occlusive crisis has significantly contributed to quality of life and life expectancy of patients with this diagnosis. Measures should continue to attempt to administer a multi-model approach to sickle cell patients to minimize the morphine milligram equivalents in these patients while also successfully addressing the patient's pain. IV lidocaine is a pain medication that has been evaluated in several painful experiences, such as in renal colic. A few case reports have shown IV lidocaine use in sickle cell can be a potential effective adjunct medication to opioids to treat pain and reduce further opioid requirements. Currently, no prospective controlled trial exists to evaluate the true benefit of IV lidocaine in this population. Our study aims to evaluate IV lidocaine as an adjunct to opioid treatment in the emergency department to determine if improved pain is achieved and if there is a reduction in overall morphine milligram equivalents throughout the emergency department visit.
Although the survival of children with sickle cell disease (SCD) has dramatically improved over the last decades in the US and Europe, mortality remains high in adults. Moreover, many children and most adults develop a chronic debilitating condition due to organ damage. Allogeneic hematopoietic stem cell transplantation (HSCT) is currently the unique curative approach; it allows the cure of more than 95% of children transplanted from a matched related donor (MRD) after a myeloablative conditioning regimen.To date, few studies have addressed the role of HSCT in SCD adults, due to the risk of graft versus host disease (GVHD) and to the toxicity expected in older patients with a higher risk of organ damage. The development of safe, non-myeloablative conditioning regimens that allow stable mixed chimerism and avoid GVHD appears as an attractive option for HSCT to cure adults with severe SCD. The investigators design a prospective multicenter trial targeting patients over 15 years with severe SCD, and compare non-myeloablative transplant (when a matched related donor (MRD) is identified) versus no HSCT (for patients lacking MRD). The main objective is to assess the benefit of HSCT on the 2-year event free survival compared to standard care. The primary endpoint is the 2-year event free survival.
The 6-minute walk (6MWT) test is used in adults and children affected by a wide range of chronic diseases to evaluate their sub-maximal exercise capacity. It reflects the global response of various physiological systems (respiratory, cardio-vascular, neurologic, metabolic and musculosquelettic) in a situation simulating a daily life activity. In children with sickle cell disease, the 6MWT is correlated with a low level of hemoglobin, a low level of fetal hemoglobin and low red cell deformability. Our team previously reported that in a population of children with sickle cell disease, highly treated with hydroxyurea, the sole factor which was independently linked to the 6MWT was the presence of silence infarct. As the cardio-vascular and cerebro-vascular injury in sickle cell disease are directly correlated with hemolysis, the investigators aim to evaluate a) the clinical relevance of endothelial and inflammation parameters and new hemolysis markers and b) if the presence of silent infarct and the 6MWT are correlated with this biological markers. This cross-sectional study will include sickle cell disease patients regularly followed for more than 5 years at Hôpital Universitaire des Enfants Reine Fabiola, Centre Hospitalier Universitaire (CHU)-Brugmann, Centre Hospitalier Etterbeek-Ixelles, CHU Saint-Pierre, Cliniques Universitaires Saint-Luc (Bruxelles, Belgium). Inclusion criteria are: sickle cell disease (SS, Sbeta°, SC, Sbeta+), age range : 6 to 25 years, signed informed consent. Exclusion criteria are: transplanted patients, inability to perform the 6MWT (severe cognitive disability, femoral osteonecrosis with functional impairment), hospitalization and/ or transfusion in the last 3 months for acute event. Demographic data and clinical data will be retrospectively recorded. Blood test and 6MWT will be performed in steady state. Studied analysis will be: coagulation factors, free hemoglobin, Pro-B type natriuretic peptide (Pro-BNP), High sensitivity C reactive protein (HS-CRP), Intercellular Adhesion Molecule (ICAM), Vascular Cell Adhesion Molecule (VCAM) and Selectins. With this study, the investigators expect to validate new predictive markers for cardio-vascular or cerebrovascular injury and to identify patients at high risk to develop these complications.
Patients with sickle cell disease often develop painful crisis without any obvious reasons. Some patients are more likely to develop this complication than others. It is now clear that painful crisis only occurs when sickled red blood cells stick to white blood cells that have been activated, usually by inflammation or infections. A recent study in mice with sickle cell disease showed that the use of long term antibiotics could reduce the number of activated white blood cells and reduce death of the mice during sickle cell crisis. The investigators believe that sickle cell patients who develop frequent painful crisis may have a different pattern of bacteria in their intestine when compared to those whose painful crisis occurs infrequently. In this study, the investigators propose to study sickle cell subject's blood to determine how many activated white blood cells he/she have. The investigators will also examine his/her stool to compare the bacteria in his/her stool to those other sickle cell patients. The investigators will then investigate whether or not the results from the blood and stool tests correlate with how frequently the patient develops painful crisis. The investigators will examine the patients' medical records to find out how many times they have been admitted to the hospital for sickle cell crisis in the last 12 months. The investigators will also obtain information on the following: their age, their sex, whether they are taking hydroxyurea or Penicillin, when they last had a transfusion or exchange transfusion therapy and painful crisis needing hospital admission, whether they have received any antibiotics (other than Penicillin) in the last 4 weeks, and whether they are experiencing a painful crisis at the time that they enter the study. The investigators will obtain, from their previous laboratory results, their levels of hemoglobin F and markers of inflammation. The investigators will check their hemoglobin F level if they have not already had this tested. The investigators expect to enroll 50 subjects into this study at Rhode Island Hospital/Hasbro Children's Hospital.
The primary objective of the proposed study is to determine the potential role of Ketamine as an analgesic agent in pediatric sickle cell disease patients with refractory symptoms in acute (VOC).
The objective of this study is to assess the efficacy of SC411 in reducing the number of sickle cell crisis (SCC) events in sickle cell disease (SCD) subjects receiving SC411 compared to those subjects receiving placebo.
140 SCD patients [70 on Hydroxyurea] will receive Omega-3 capsules whereas another 140 SCD patients [70 on Hydroxyurea] will receive placebo and will be recruited from the Sultan Qaboos University Hospital [SQUH] haematology specialty clinics. Patients will be randomized in a 1:1 ratio to receive placebo or Omega-3 for 52 weeks. The aim is to investigate the therapeutic potential of omega-3 fatty acids in the prevention of vaso-occlusive crisis in Omani patients with sickle cell disease[SCD].
Interventional Allocation: Randomized Endpoint Classification: Safety/Efficacy Study of combined chelation therapy Masking: Open Label Primary Purpose: Treatment of transfusional iron overload Primary Outcome Measures: • The primary outcome measure is to assess efficacy in lowering serum ferritin level(the change in serum ferritin compared to baseline) with combining DFP and deferasirox compared to combined DFP and DFO in conditions with severe chronic iron overload; showing an up-trend of SF over previous 12 months on single chelator. Secondary Outcome Measures: • The secondary outcome measure is to determine the number of patients who will develop adverse events in order to assess safety upon administering the drugs in combination (DFP and DFX) compared to the combination of DFO and DFP.
