NCT ID: NCT03719729 Recruiting - Sickle Cell Disease Clinical Trials

Rifaximin to Modify the Disease Course in Sickle Cell Disease

Start date: August 22, 2018
Phase: Phase 2
Study type: Interventional

In this single-arm, one-stage Phase II study, we hypothesize that gut decontamination with rifaximin will reduce the frequency of hospital admission due to painful crisis in patients with SCD. We will accrue 20 SCD patients who had at least two hospital admissions in the previous 12 months. These patients will receive rifaximin 550 mg twice a day for a total of 12 months. This following clinical parameters will be measured: 1. Changes in the annual rate of hospital admissions due to painful crisis; 2. Changes in the annual rate of days hospitalized; 3. Annual rates of uncomplicated crises; 4. Annual rate of acute chest syndrome; 5. Changes in the quality of life; and 6). Toxicities. The following laboratory parameters will be measured: 1. Changes in the number of circulating activated neutrophils; 2. Changes in the intestinal microbiome diversity; 3. Changes in the urinary 3-indoxyl sulfate levels; 4. Changes in the serum biomarkers of intestinal permeability (lipopolysaccharides; zonulin, citrulline, and fatty acid binding proteins).

Sickle Cell Anemia WE CARE

Start date: April 2019
Phase: N/A
Study type: Interventional

This mixed-methods study aims to understand the implementation of a previously tested, efficacious SDOH screening and referral intervention in the outpatient pediatric hematology setting; qualitatively assess possible mechanisms for such interventions on improving child health; and obtain population-specific empirical estimates to plan a large-scale clinical trial.

NCT ID: NCT03715972 Recruiting - Sickle Cell Disease Clinical Trials

Cerebrovascular Reserve and White Matter Disease in Patients With Chronic Anemia

Start date: July 15, 2018
Study type: Observational

This is primarily an observational trial in patients with chronic anemia syndromes (sickle cell disease and thalassemia) and control subjects. The key purpose is to understand how brain blood flow reserve (the ability of the brain to increase its flow in response to stress) is altered in patients with chronic anemia. Since this parameter may depend on anemia severity, we will perform the MRI monitoring prior to and following clinically indicated transfusions in a subset of patients. Most patients will already be prescribed hydroxyurea as part of their standard of care. Since hydroxyurea could impact brain blood flow, there is also a small pilot study (20 patients, nonrandomized, open label) where MRI imaging will be performed prior to and following administration of hydroxyurea up to maximum tolerated dose. The study will enroll 90 adult subjects with transfusion independent sickle cell disease (70 SS, 10 SC, 10 Sβ0) and 60 patients with transfusion-dependent sickle cell disease. It will also include 10 transfusion independent thalassemia patients and 20 transfusion dependent thalassemia patients as well as 40 control subjects recruited from first degree relatives of the sickle cell disease population. All eligible subjects will be asked to provide informed consent before participating in the study.

NCT ID: NCT03709303 Recruiting - Sickle Cell Disease Clinical Trials

Motivations, Expectations, and Decision-making of Sickle Cell Patients in Clinical Research

Start date: November 15, 2018
Study type: Observational

Background: Sickle cell disease is an inherited blood disorder. People with this disease have a problem with their hemoglobin. That is a protein in red blood cells that carries oxygen in the body. Some people with this disease are enrolled in research at NIH. Researchers want to learn more about the thoughts and opinions of those people. This may improve the way researchers explain clinical studies, risks, and benefits to people with the disease. Objective: To learn about the motivations, decisions, and experiences in clinical research of people with sickle cell disease. Eligibility: Adults ages 18 and older who have sickle cell disease. They must be in an NIH study on this condition. They must have been invited to join either a gene therapy or peripheral blood stem cell transplantation study. Design: Participants will have 1 interview. It will be done in a quiet room in the NIH Clinical Center or by video call. It will take about 60 minutes. The interview will be audio-recorded if the participant agrees. Participants will be asked about: - Their experiences with and thoughts on sickle cell disease - Their decision to participate in clinical research - Factors that may have affected their decision to participate. These may include family, disease history, or faith. Participants may complete a few brief questionnaires.

NCT ID: NCT03708731 Recruiting - Sickle Cell Disease Clinical Trials

Exploring Adherence Monitoring in Sickle Cell Disease

Start date: November 2018
Study type: Observational

Despite the well-documented benefits of hydroxyurea (HU) therapy in decreasing morbidity and mortality in youth with Sickle cell disease (SCD), pediatric HU adherence rates range as low as 49% and lead to discontinuation of HU regimens in 8-20%. In addition, treatment non-adherence may lead to unnecessary increases in medication dosage resulting from erroneous assumption that a patient is non-responsive to treatment (versus non-adherent to the regimen as prescribed). Given the detrimental effects of non-adherence, assessment of and intervention for HU non-adherence is essential to improving health outcomes in the pediatric SCD population. Electronic adherence monitoring is widely considered the "gold standard" in objective adherence measurement. These monitors provide continuous, real- time records of medication adherence and reveal problematic behavior patterns, including underdosing, overdosing, delayed dosing, "drug holidays," and "white coat" adherence. Overall, electronic adherence measures are considered valid, reliable, and accurate, with clear advantages over pharmacy refill records, physician estimates and self-report measures. The primary purpose of this pilot study is to determine the use of the AdhereTech as a feasible and valid measure of HU adherence in pediatric SCD. Primary Objective Estimate the association between HU adherence as measured by the AdhereTech device to a) caregiver-report, b) youth-report, c) lab values, d) pill- count, and e) Medication Possession Ratio (MPR) adherence measures Secondary Objectives Estimate the rate of consent to the study, the rate of AdhereTech device use, the rate of AdhereTech device failure, and the perceived acceptability of using the AdhereTech device, as reported by caregivers and youth

NCT ID: NCT03704922 Recruiting - Sickle Cell Disease Clinical Trials

Age of Blood in Sickle Cell Transfusion

Start date: October 1, 2018
Phase: Phase 2/Phase 3
Study type: Interventional

The Investigators hypothesize that older red cell units trigger phagocytosis and activation of circulating macrophages with a downstream immunomodulatory cascade and release of excess Non Transferrin Bound Iron(NTBI) that leads to increased rates of infection in adults with Sickle Cell Disease(SCD). To test this hypothesis, the study staff will perform a randomized prospective clinical trial. In aim 1, the study staff will determine the biochemical differences between ≥30 day-old versus ≤10 day-old units. In aim 2, the study staff will determine the physiologic effects of the transfused blood in a patient with SCD. Lastly, in aim 3, the study staff will explore the clinical implications of receiving older red cells over a 3 month period.

NCT ID: NCT03694548 Recruiting - Sickle Cell Disease Clinical Trials

Acceptability, Feasibility and Safety of a Yoga Program for Chronic Pain in Sickle Cell Disease

Start date: October 2018
Phase: N/A
Study type: Interventional

Chronic Pain is associated with morbidity and poor quality of life in patients with Sickle Cell Disease (SCD). Complementary therapies, such as yoga are beneficial in patients with non-SCD chronic pain conditions. Yoga was shown to be acceptable, feasible and helpful in one study in acute SCD pain. The purpose of the study is to assess the acceptability, feasibility, and safety of yoga for chronic pain in SCD.

NCT ID: NCT03682211 Completed - Pain Clinical Trials

Intranasal Fentanyl Versus Intravenous Morphine in the Treatment of Severe Painful Sickle Cell Crises in Children

Start date: December 12, 2012
Phase: Phase 4
Study type: Interventional

Sickle cell anaemia is an inherited blood disorder which results in abnormal sickle shaped red blood cells which do not fit well through small blood vessels. These blockages prevent oxygen (in blood) from reaching different parts of the body resulting in painful crisis. This study will compare the effectiveness of two types of pain medication, one given through a vein and one squirted up the nose.
