Filter by:The University of Illinois Health and Health Sciences System (UI Health) developed an integrated care management quality improvement model designed to provide comprehensive care coordination for Medicaid insured minority children and young adults with chronic health conditions living in Chicago. This program, called CHECK (Coordinated HEalthcare for Complex Kids), targeted children and young adults with chronic disease.
A randomized control trial in 20 subjects with sickle cell disease comparing oral THU-decitabine to nicotinamide and in combination (THU, decitabine and nicotinamide).
This is an open-label extension study of IMR-687 in adult patients who completed Imara's blinded Phase 2a study (IMR-SCD-102). The open-label extension study will evaluate long-term safety and tolerability.
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.
In this prospective observational study among sickle cell children aged 7 to 17 years, who face many experience of pain, pain will be assessed during incentive spirometry sessions. Then a relation between, inspiratory volume, pain and the length of hospital stay will be identified . Currently, there is no scientific data regarding the correlation between acute pain during vaso-occlusive crisis, incentive spirometry and the impact on length of hospital stay. In fact, physiotherapist experience's in the pediatric department suggests that the pain expressed by the child is not always correlated with inspiratory capacity. The absence of pain is one of the reasons for hospital discharge after decompensation in patients with sickle cell disease. However, no scientific study has linked incentive spirometry, pain and length of hospital stay. Investigator assume that these children underestimate the real pain and its impact on breathing pattern, and presume that the maximal inspiratory volume during spirometry sessions will be a better reflect of pain than standard pain scale. The aim of this study is to show that inspiratory volume would be a better indicator of discharge from hospitalization than actual pain scales.
Endothelial dysfunction contributes to vaso-occlusion and acute pain in sickle cell disease. Near infrared spectroscopy (NIRS) technology can measure tissue oxygenation and endothelial function. The main objective of this study is to study the natural history of tissue muscle oxygenation using NIRS in pediatric sickle cell subjects experiencing acute pain and pediatric sickle cell patients in steady-state.
This study aims to enroll 58 pre-adolescent (<13 years) pediatric participants with sickle cell disease (SCD) who have a pre-adolescent sibling bone marrow donor. All participants will go through a pre-transplant evaluation to find out if there are health problems that will keep them from being able to receive the transplant. It usually takes 2 to 3 months to complete the pre-transplant evaluation and make the arrangements for the transplant. Once they are found to be eligible for transplant, participants will be admitted to the hospital and will start transplant conditioning. Conditioning is the chemotherapy and other medicines given to prepare them to receive donor cells. It prevents the immune system from rejecting donor cells. Conditioning will start 21 days before transplant. Once they complete conditioning, participants will receive the bone marrow transplant. After the transplant, participants will stay in the hospital for 4-6 weeks. After they leave the hospital, participants will be followed closely in the clinic. Outpatient treatment and frequent clinic visits usually last 6 to 12 months. Routine medical care includes at least a yearly examination for many years after transplant by doctors and nurses familiar with sickle cell disease and transplant. The researchers will collect and study information about participants for 2 years after transplant.
Pain is the most common component of the morbidity seen in sickle cell disease (SCD), and may be acute or chronic. It is most commonly acute and a result of the hallmark vaso-occlusive episodes of the disease. Many patients however suffer from chronic pain - defined as pain lasting over three months- with neuropathic pain being a component of chronic pain. Neuropathic pain significantly contributes to the chronicity and morbidity of pain in SCD patients, and is an inadequately managed complication. There is a paucity of literature covering this area, and it has never been examined in the Jamaican population. The main objective of this study is to determine the epidemiology of pain among Jamaicans with SCD, and determine the prevalence of chronic and neuropathic pain among these patients. A second objective is to validate, using gold-standard measures, screening tools to determine neuropathic pain among the study population. This cross-sectional study will investigate the prevalence of neuropathic pain and complications in a sample of persons with SCD in Jamaica aged 14 years and older, with a validation sub-study to be conducted on a random 20 percent of the sample. With improved diagnosis of neuropathic pain, clinicians may potentially improve the management of pain in SCD, as clinicians should be able to direct our treatment toward medications and non-pharmacological methods of pain relief that are more specific for neuropathic pain. All data will be de-identified and maintained in a secure database, with access limited to key personnel. There is very minimal risk to participants.
Background: Sickle Cell Disease (SCD) is an inherited blood disorder. People with SCD have abnormal hemoglobin in their red blood cells. Researchers are investigating the safety and efficacy of an investigational medicine called AG-348 (mitapivat sulfate) to determine if it will help people with SCD. Objective: To test the tolerability and safety of AG-348 in people with SCD. Eligibility: People ages 18 and older with SCD. Design: Participants will have 8 visits over approximately 14 weeks. At the first visit participants will be screened with a medical history, a physical exam, blood and urine testing, and an EKG. During the following 5 visits, participants will stay at the clinic for 1 night each. Participants will take study drug in increasing doses up to visit 6, after which the drug will be tapered off. All visits will include physical exam, blood, and urine tests. The last visit will occur 4 weeks after stopping the drug. Participants will provide DNA from the blood samples they provide. The DNA will be tested for an inherited gene that can cause differences in response to the study drug. Researchers may also test other genes to see if they can find any genes that interact with SCD.
In this protocol, the investigators propose to evaluate the biochemical effects of imatinib on sickle red blood cells (RBCs). Patients will be administered imatinib mesylate orally following the guidelines previously established for use of imatinib in other disorders. The biochemical effects of imatinib on sickle RBCs will be examined, including changes in their levels of band 3 tyrosine phosphorylation and the abundances of RBC-derived microparticles in their blood. In addition, the patients will be monitored for symptoms of sickle cell disease (SCD). The investigators expect band 3 tyrosine phosphorylation to decrease dramatically in patients treated with imatinib. The investigators also anticipate a reduction in the numbers of RBC-derived microparticles in circulation (quantitated by assaying the number of glycophorin A positive microparticles in peripheral blood samples by flow cytometry. Most importantly, the investigators expect to see a reduction in the frequency of vaso-occlusive crises, and possibly acute chest syndrome and utilization of opioids. The study duration is planned as 6 months in order to provide adequate time for potential change in the primary endpoints (e.g. percent irreversibly sickled cells).
