Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: People with sickle cell disease (SCD) have problems with their heart, brain, kidneys, liver, and lungs as they age. These problems may improve after transplant. Researchers want to learn how and why this happens. Objective: To study the benefits of treatments that are intended to cure SCD. Eligibility: People aged 18 and older with SCD who are either receiving curative therapy in the next 3 months or don t have any plans to receive a curative therapy in the next 2 years. Design: At their first visit, participants will be screened with their medical history and a physical exam. Participants will then have a baseline visit. This will take about a week to complete and will include: Blood and heart tests MRI of the brain, heart, and lungs. Participants will lie on a bed that will move into the MRI scanner. Special padding may be placed around their head to keep it still. Interactive games. Participants will complete computer games that test memory, attention, problem solving, language, spatial orientation, processing speed, and emotion. Questionnaire rating quality of life Iothalamate test. An IV catheter will be placed into a vein. A contrast agent will be injected through the IV. Blood will then be collected at different time points. Lung function tests and a 6-minute walk test Vibration controlled transient elastography. A probe placed on the abdomen will measure liver scarring. DOS test. A light attached to the finger or toe will measure blood oxygen. Participants will have an end-of-study visit about 2 years after their baseline visit. This will include repeats of the baseline visit tests.
