Filter by:Exposure to secondhand smoke is a leading preventable cause of child morbidity and mortality, and the adverse health consequences of secondhand smoke are magnified among youngsters with cancer and sickle cell disease. Current methods for measuring secondhand smoke exposure (SHSe) rely on retrospective reports over extended time periods that are subject to recall errors and systematic inaccuracies in reporting and often do not include the youngster as the primary informant. These methods may underestimate the extent of cumulative SHSe and are not well suited to capturing exposure over time and across settings where young people frequent. More appealing methods that engage youngsters to better monitor tobacco smoke in their environment are warranted. The study will examine the feasibility of cell phone texting to obtain measures of secondhand smoke exposure (SHSe) in children treated for cancer or sickle cell disease (SCD).
Allogeneic Stem Cell Transplantation of NiCord®, Umbilical Cord Blood-Derived Ex Vivo Expanded Stem and Progenitor Cells, in Patients with Hemoglobinopathies
Acute chest syndrome (ACS) is a frequent complication of sickle cell disease and is diagnosed by having findings on a chest x-ray and one of the following: chest pain, fever, or trouble breathing. Patients with Acute Chest Syndrome can get very sick and require an exchange transfusion (special large blood transfusion) and mechanical ventilation. Bi-level Positive Airway Pressure (also known as BLPAP or BiPAP) is a device that blows air into a patients lungs via a mask that covers the nose. The goal of this study is to determine whether giving children BiPAP when they have ACS, in addition to providing standard clinical care for ACS, alters the clinical course of these patients. The investigators hypothesize that patients receiving effective BiPAP will have milder clinical courses resulting in shorter hospital stays and fewer transfers to the intensive care unit and exchange transfusions.
Sickle cell disease (SCD) is a debilitating genetic disorder affecting 70,000-100,000 Americans. It is frequently associated with very serious medical complications. For children with SCD, successfully transitioning to adult care is a vital step in ensuring continuity of care, managing their disease, and improving their health outcomes. Transition programs have been created to facilitate the transition process. However, few studies have assessed transition readiness and whether transition program components meet the transition needs of patients and families. The purpose of this study is to explore transitioning from pediatric care to adult care and to assess components of the SJCRH SCD Transition Program from three perspectives: adolescents with SCD, their caregivers, and young adults with SCD who have transitioned to adult care. Data collection methods will include focus groups, questionnaires, and checklists. Qualitative data analysis procedures will be used to examine the data.
Background: - Many people with sickle cell disease have repeated episodes of severe pain that lasts for days, requiring hospital care. These episodes, called pain crises, may be caused by changes in blood flow. Researchers want to study blood flow in people with sickle cell disease who are having a pain crisis and compare it with their blood flow after the pain crisis has resolved. They also want to compare these measurements against blood flow in healthy people who do not have sickle cell disease. Objectives: - To study whether changes in blood flow cause pain crises in people with sickle cell disease. Eligibility: - Individuals at least 18 years of age who have sickle cell disease and are being treated for a pain crisis. - Individuals at least 18 years of age who have sickle cell disease and are not experiencing a pain crisis. - Healthy volunteers matched by age and gender with the participants who have sickle cell disease. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. - Participants having a sickle cell pain crisis will have two visits, one during the crisis and one about 4 weeks after the crisis has resolved. - Participants not having a sickle cell pain crisis will have one or two study visits. Blood samples will be collected during at least one of these visits. - Healthy volunteers will have one or two study visits. Blood samples will be collected during at least one of these visits. - During each visit for all participants, cameras and blood flow monitoring equipment will be used to measure blood flow in the forearm. sickle cell disease.
Background: - About one-tenth of adults with sickle cell disease have pulmonary hypertension (high blood pressure in the lungs). This condition can cause shortness of breath, pain crisis, and congestive heart failure. It may even lead to death. Researchers want to test the drugs imatinib and carvedilol to see if they can treat high blood pressure in the lungs. Both drugs have been used to treat other types of heart problems, but they have not been tested as a treatment for high blood pressure related to sickle cell disease. Objectives: - To see if imatinib and carvedilol are safe and effective treatments for high blood pressure in the lungs in adults with sickle cell disease. Eligibility: - Adults at least 18 years of age who have sickle cell disease and have or may have high blood pressure in the lungs. Design: - Participants will be screened with a physical exam and medical history. They will also have different tests of heart and lung function, including a walking test and imaging studies. Blood and urine samples will also be collected. - Participants who meet specific criteria will take one of two possible study drugs. Those who receive imatinib will take it daily. Those who receive carvedilol will take it twice a day. - Participants will have weekly study visits for blood tests and other exams. The study drug dose will be adjusted at each weekly visit. It will be increased slowly to reach a target dose(based on the participant s weight) or to find a stable effective dose. - Participants may continue to take their study drug for up to 24 weeks, with weekly study visits. Regular blood samples and heart and lung function tests will be performed. - After 24 weeks, qualified participants may continue to take their study drug for up to 6 more months. They will have regular study visits to monitor the treatment.
Sickle cell disease (SCD) is an inherited blood disorder that causes the red blood cells to change their shape from a round shape to a half-moon/crescent or sickled shape. Sickle-shaped cells can cause problems by getting stuck in blood vessels, blocking blood flow, and can cause inflammation and injury to important body parts. There are no specific treatments that improve this condition and promote blood flow hindered by sickle cell blockages. Another big challenge in managing sickle cell disease is that there are no good measures to determine changes and improvements in blood flow. Contrast-enhanced ultrasound is a technique currently used to detect blood flow in the heart, muscles, and other organs. It is extremely sensitive and can detect blood flow in the smallest of blood vessels. It would be very useful in helping healthcare providers know whether treatment strategies are improving blood flow during sickle cell blockages. The hypothesis is that contrast-enhanced ultrasound will be a feasible tool for determining changes in blood flow of subjects with sickle cell disease.
In Sickle cell disease children, sleep respiratory abnormalities are risk factors for vaso-occlusive complications, as well as cerebral vasculopathy. A 18 months follow-up children with sickle cell disease evaluating sleep respiratory problems frequency and etiology, as well as their influence on sickle cell disease complications.
This is a Phase II, single arm, multi-center trial. It is designed to estimate the efficacy and toxicity of hematopoietic stem cell transplantation (HSCT) in patients with sickle cell disease (SCD) who have high risk features. The primary goal of this multi-center Phase II study is to determine the safety and feasibility of a conditioning regimen consisting of busulfan (Bu)/ fludarabine (Flu)/ anti-thymocyte globulin (ATG) in adult patients with severe SCD. A two-component design will be used for this study. The first component will be restricted to patients who have an HLA-identical sibling donor. Five patients will be transplanted during the first component of the study. If no more than 2 of the first 5 patients experience unacceptable toxicity, including death, within the first six months after transplantation, then the safety of the regimen will be considered promising in adult SCD patients. The second component will include patients who have a related or an unrelated human leukocyte antigen (HLA) matched donor. Up to 15 additional patients will be transplanted in this component of the study which will evaluate the safety and feasibility of unrelated donor hematopoietic cell transplantation (HCT) in adults with SCD. Data related to study endpoints for 1 year after transplantation will be collected; however, participating centers will be encouraged to conduct long-term follow-up evaluations of patients according to standard institutional guidelines. The purpose of this pilot safety trial is to see if this approach is feasible and meets accrual goals lending support to the development of a subsequent full scale investigation of HCT and comparing outcomes in a transplantation cohort to a control cohort of adults eligible for, but unwilling or unable to receive HCT treated by supportive therapy with a primary endpoint of five years survival for this full scale comparative trial.
The purpose of this study is to use comprehensive exercise testing to examine longitudinal changes in exercise capacity over a 2 year period in children and young adults with sickle cell anemia.
