Active clinical trials for "Anemia, Sickle Cell"

Background: - Assessing pain levels is important to improve treatments for different illnesses. Most pain rating scales are used to determine pain levels in adults. Pain is also a common symptom among children who have cancer. Those who have genetic conditions that may lead to cancer may also have pain symptoms. However, the pain scales used for adults have not been fully tested in children and young adults. As a result, they may not be as accurate. Researchers want to test pain rating scales in children and young adults who have cancer and genetic conditions that can lead to cancer. Objectives: - To study the effectiveness of pain rating scales given to children and adults with Sickle Cell Disease (SCD),cancer, and related genetic conditions. Eligibility: - Adults 18 and 34 years of age and older who have SCD, cancer, or other genetic conditions that can lead to cancer. Design: Participants with SCD, cancer or related genetic conditions will fill out four questionnaires. These questionnaires will ask about pain levels and how much pain interferes with daily life. Pain treatments will not be provided as part of this study.

To determine the retinal and choroidal thickness in patients with sickle cell disease compared to age, race matched population without sickle cell disease to allow a better understanding of the clinical manifestations of sickle cell retinopathy. The purpose of this research study is to evaluate the relationship between sickle cell disease and the eye. The research study is recruiting African American population with or without Sickle Cell Disease. The investigator in charge of this study is Dr E. Bowie. Approximately 60 subjects of both sexes will be enrolled at the Medical University of South Carolina.

Background: - Some people with sickle cell disease have different health problems than others. This may be related to how easily and frequently the red blood cells break apart in the blood. Researchers want to test breath and blood samples from people with sickle cell disease to look for very small amounts of carbon monoxide, which is produced when red blood cells break apart. They will compare these results with breath samples from healthy volunteers. Studying different levels of carbon monoxide may help predict what health problems a person with sickle cell disease may get. It may also provide more information on possible treatments. Objectives: - To study breath carbon monoxide levels and their possible relation to the severity of sickle cell disease. Eligibility: Individuals at least 18 years of age with sickle cell disease. Healthy volunteers who are matched for age, sex, and race with the sickle cell disease group. Design: Participants will be screened with a medical history. Participants with sickle cell disease will provide a blood sample and have a heart function test. They will also breathe into a bag to provide an exhaled breath sample. Healthy volunteers will provide an exhaled breath sample. No treatment or care will be provided as part of this study.

To assess in older children and adults with sickle cell disease (SCD) whether intrinsic activation (relevant to the origin of pain and acute inflammation) occurs only during vasocclusive crisis (VOC).

The purpose of this study is to test a web-aided, mobile-based PHR (Personal Health Reporting) service to enhance SCD outpatient treatment after discharge from an acute care setting, such as Duke University Medical Center's Day Hospital. SMART is a new mobile application created by SickleSoft to increase patient involvement in their treatment and improve patient to doctor communication. SMART is a self-monitoring and management service for SCD patients and their treatment doctors. This study will test whether or not use of the SMART mobile application will help develop the type of patient-doctor relationships that lead to better health outcomes and a decrease in readmission to an acute care facility.

The use of hydroxyurea in sickle cell disease patients with glomerular hyperfiltration and renal failure requires a specific monitoring and dose adjustment in order to remain within the therapeutic interval while limiting the risk of toxicity or therapeutic failure. For this reason the investigators propose to compare the pharmacokinetic parameters of hydroxyurea in normal-renal function sickle cell patients to those of patients with glomerular hyperfiltration or moderate renal failure.

Staying out of the hospital is valued by patients and their caregivers. Their interests converge with those of hospitals now that high 30-day readmission rates for some conditions place hospitals at risk for financial penalties from the Centers for Medicare and Medicaid Services. This study focuses on developing and testing a program that combines a community health worker (lay patient advocate, acting as a "Patient Navigator") and a peer-led telephone support line to improve patient experience during hospital to home transition.

The purpose of the study is to determine whether imaging techniques, such as magnetic resonance imaging (MRI), near infrared spectroscopy (NIRS), laser speckle contrast imaging (LSCI), and optical imaging (OI), can detect differences in blood flow and oxygen levels in different organ systems of participants with sickle cell disease (SCD). Differences in blood flow and oxygen levels detected by these techniques will be evaluated to determine their utility as biomarkers of clinical disease pathophysiology.

The Emergency Department has been the standard location where patients with Sickle Cell Disease (SCD) go to seek care for the treatment of acute painful events. Vaso- Occlusive Crisis (VOC) is the most common complication of SCD, The purpose of this study is to compare patient centered outcomes for patients being treated for an uncomplicated VOC in Infusion Centers (IC) and Emergency Departments (ED) in four locations around the United States.

Sickle cell disease is a genetic disease responsible for an abnormal hemoglobin.The anomaly has several consequences: a low hemoglobin rate (chronic anemia), plugs formed by red blood cells in blood vessels (extremely painful vaso-occlusive crises) and greater susceptibility to infections. Patients with this disease should be monitored medically continuously from birth. At adulthood, they will pass from a pediatric medical care system to an adult medical care system.This transition can be experienced with more or less ease, depending on the organization within the pediatric and adult hospitals. This questionnaire aims to assess the quality of the transition between pediatric and adult services.The investigators want to better estimate hospital work and improve the quality of care for this type of patients, throughout their entire medical history.
