What is this study?
This study will examine sleep disordered breathing and sleep quality in participants (ages 12-25) diagnosed with sickle cell disease of any genotype. We will utilize remote peripheral arterial tonometry (PAT) and questionnaires to evaluate difficulties with sleep.
It is , overseen by an independent and licensed medical staff.
Read the full clinical description
This study will examine sleep disordered breathing and sleep quality in participants (ages 12-25) diagnosed with sickle cell disease of any genotype. We will utilize remote peripheral arterial tonometry (PAT) and questionnaires to evaluate difficulties with sleep. PAT assessments will occur remotely in the homes of participants. Neurocognitive, behavioral, and neuroimaging evaluations will occur on the same day as a routine clinic visit. Primary Objective: Evaluate the relationship between nocturnal oxyhemoglobin saturation (SpO2) and neurocognitive functioning (working memory and verbal comprehension) in individuals (ages 12-25) diagnosed with sickle cell disease controlling for age, genotype, and social vulnerability. Secondary Objective: Assess differences in white matter integrity, silent cerebral infarcts, neuroinflammation, and functional connectivity among individuals (ages 12-25) diagnosed with sickle cell disease with and without sleep disordered breathing after controlling for age. Assess differences in self- and caregiver-reported mood and pain severity among individuals (ages 12-25) diagnosed with sickle cell disease with and without sleep disordered breathing after controlling for age. Exploratory Objectives: Explore the relationship between nocturnal oxyhemoglobin saturation (SpO2) and neurocognitive functioning (attention, processing speed, verbal memory, visual memory, motor dexterity) in individuals (ages 12-25) diagnosed with sickle cell disease controlling for age, genotype, and social vulnerability. Assess the feasibility of an optical imaging tool (Speckle Contrast Optical Spectroscopy - Open-Motion 3.0) to measure cerebral blood flow and blood volume in patients diagnosed with sickle cell disease (ages 12-25). Assess the concordance between measurement of cerebral blood flow and volume using speckle contrast optical spectroscopy and arterial spin labeling brain MRI.

Treatment
If you join and choose to continue, you receive the study treatment and are watched closely by medical staff.

Follow-up
After treatment, the team checks on your health and confirms the visit schedule with you. You can leave the study at any point.

What you need to know before you apply
What is this study testing?+
This study will examine sleep disordered breathing and sleep quality in participants (ages 12-25) diagnosed with sickle cell disease of any genotype. We will utilize remote peripheral arterial tonometry (PAT) and questionnaires to evaluate difficulties with sleep.
Is it safe? Who makes sure of that?+
This is a research study. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.
Will I get a placebo instead of the real treatment?+
Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.
Do I have to stop taking my current medications?+
It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.
Does it cost anything? Will I be paid?+
Study-related care is provided at no cost to you. Some studies also pay for your time; the coordinator can tell you if this one does. You should never be asked to pay to take part.
Do I need insurance? Will anyone ask about my immigration status?+
No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.
What if English isn't my first language?+
You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.
Is my information private?+
Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
Some requirements (like specific lab values or timing) are confirmed directly by the study team, not by us.
