Lidocaine Intravenous in the Emergency Department For Sickle Cell Crisis

RELIEF-SCC
Start date: January 1, 2024
Phase: Phase 2
Study type: Interventional

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.

Comparison of Allogeneic Matched Related Haematopoietic Stem Cell Transplantation After a Reduced Intensity Conditioning Regimen With Standard of Care in Adolescents and Adults With Severe Sickle Cell Disease

DREPA-RIC
Start date: October 15, 2019
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT03040908 Not yet recruiting - Sickle Cell Disease Clinical Trials

New Hemolysis Parameters in Sickle Cell Disease

HEMODREP
Start date: September 1, 2019
Phase:
Study type: Observational

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.

NCT ID: NCT03007849 Not yet recruiting - Sickle Cell Disease Clinical Trials

A Pilot Study of Fecal Microbiome and Neutrophil Cellular Adhesion Molecules in Patients With Sickle Cell Disease (SCD)

Start date: January 2017
Phase: N/A
Study type: Observational

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.

NCT ID: NCT02004808 Not yet recruiting - Sickle Cell Anemia Clinical Trials

Neutrophil Extracellular Traps and Sickle Cell Disease

Start date: February 2014
Phase: N/A
Study type: Observational

NETs formation in vaso-occlusive events in sickle cell disease and the role of hydroxyurea treatment.The study hypothesis is that NETs formation by neutrophils has a role in the induction of vaso occlusive disease in blood vessels. It is possible that high leukocyte count in children with sickle cell anemia is a bad prognostic sign due to NETs formation supporting occlusion of peripheral and central blood vessels.Hydroxyurea treatment might prevent vaso occlusive syndrome not only by increasing HbF but also by decreasing neutrophil count and inhibiting NETs formation.
