Sickle cell disease (SCD) is an autosomal recessive genetic disorder linked to a single mutation on beta-globin chains. This leads to red blood cell deformation and chronic hemolysis which can result in vaso-occlusive events, anemia and vasculopathy. Pathophysiology is incompletely understood, and beyond red blood cell's abnormalities this involves hemostasis and innate immunity. The aim of our study is to describe the mechanisms of thrombo-inflammation during the vaso-occlusive crisis (VOC) in adults with sickle cell disease.
The investigators are evaluating the role of a low dose of tocilizumab in treating acute chest syndrome in patients with sickle cell disease. Tocilizumab inhibits interleukin-6 (IL-6) receptors and is used to treat rheumatoid arthritis and severe cytokine release syndrome, which can be seen with chimeric antigen receptor T-cell (CAR-T) therapy, and it is also authorized for treatment of COVID-19. Since IL-6 levels are elevated in the sputum of patients with acute chest syndrome, the investigators are hopeful that this will be an effective strategy. The investigators will be looking at how a low dose of tocilizumab affects oxygen status, clinical outcomes, and laboratory markers in patients admitted to the hospital with acute chest syndrome.

An Open-label Extension Study of GBT021601 in Participants with Sickle Cell Disease
Background: Sickle cell disease is the most common monogenic disease in the world caused by a mutation in the β-globin gene which creates abnormal hemoglobin called HbS. This polymer deforms the erythrocyte, making it more fragile and less flexible, thus leading to the occlusion of small blood vessels. This obstruction is the cause of painful vaso-occlusive crises and ischemia-reperfusion phenomena. Patients with sickle cell disease undergo major acute and chronic pain responsible for a significant deterioration in their quality of life and a significant consumption of analgesics, often daily, sometimes with the development of addictive behavior. Improved analgesic management was associated with improved disease prognosis. Several studies have shown the effectiveness of the osteopathic approach in the management of chronic pain. Our hypothesis is that the association with the standard treatment of osteopathy sessions could improve but also prevent the chronic pain frequent in patients with sickle cell disease. Objectives: Our main objective is to study the effectiveness of an osteopathic treatment in adult sickle cell patients with chronic pain on the reduction of the consumption of level I and II analgesics at 3 months (D90 +/- 15 days). Methods/Experimental design: This is a single-blind prospective randomized controlled monocentric study. The study population will be composed of 37 sickle cell patients aged over 18 years. The patients included will be allocated into two groups: one group will receive the osteopathic treatment and the 2nd group will receive the "placebo" treatment. Analgesic consumption will be assessed by weekly self- questionnaire. The evaluation of the pain will be carried out by the visual analogue scale (VAS). The degree of stress will be measured using the Perceived Stress Scale (PSS). Patients will receive an osteopathic treatment or a "placebo" treatment, one session every 4 weeks for 12 weeks with a total of 3 sessions per patient. The duration of each session is 45 minutes. Pain and stress assessments will be done before each session. A final evaluation will be carried out 3 months after the end of the osteopathic or "placebo" treatment. Data analysis will be performed using SPSS version 17.0 software. The significance threshold will be set at 0.05. This is the first protocol that aims to evaluate, with scientific rigor, the impact of the osteopathic approach in the management of pain in patients with sickle cell disease.
Hematopoietic stem cell (HSC)-based gene therapies now offer curative potential for patients with sickle cell disease (SCD), with decreased toxicity compared to allogeneic hematopoietic cell transplantation. However, effective HSC-based gene therapy depends on collecting sufficient HSCs to generate the therapeutic product, and currently available mobilization regimens carry unacceptable risk for patients with SCD or do not reliably yield optimal numbers of HSCs for gene therapy. The investigators hypothesize that HSC mobilization with motixafortide (CXCR4i) alone and the combination of motixafortide plus natalizumab (VLA-4i) will be safe and tolerable in SCD patients. In addition, the investigators hypothesize that combined CXCR4 and VLA-4 blockade with motixafortide plus natalizumab will result in a rapid, robust, and synergistic increase in HSC mobilization to peripheral blood (PB) in patients with SCD, when compared to motixafortide alone.
Sickle cell disease (SCD) is a common, inherited blood disorder that primarily affects people of African Ancestry. It has a lot of complications including neurological complications. The neurological complications of SCD are particularly devastating and lead to cognitive decline even in the absence of overt brain injury. In such cases, it is thought that inflammation in the brain maybe partly responsible for the cognitive decline. The main reasons for this research study are to see 1) how safe and 2) how well minocycline works to try to stop/reverse cognitive decline in people with SCD. People with SCD are at risk for changes in their brain over time that can cause problems with learning, memory, and attention. Part of the reason for this is inflammation within the brain. Minocycline may be able to stop these brain changes by stopping this brain inflammation. Minocycline is a second-generation tetracycline antibiotic that has been shown to both inhibit neuroinflammation and improve cognitive function in a variety of neurodegenerative and psychiatric disorders but has not yet been studied in SCD. We are proposing here, a pilot double-blinded, randomized controlled trial to examine the tolerability and early efficacy of minocycline in adults with SCD at two dosing regimens (200 mg and 300 mg daily) versus placebo over one year. Participants will undergo a neuropsychological exam using the NIH Toolbox Cognition Battery at both study enrollment and exit (after one year) to assess for changes/stability of cognition. Participants will receive monthly phone calls/text messages to assess for adverse events and will be seen every three months for pill counts and routine laboratory monitoring. The primary outcome will be a comparison of adverse events across the two dosing strategies versus placebo. Early evidence for cognitive benefit will also be assessed from the results of the NIH Toolbox.
There is limited information on what causes injury to the heart in individuals with Sickle Cell Disease (SCD). Researchers in this study want to see if decreased blood flow to the heart during stress could be causing the heart damage seen in SCD patients. They also want to test people who don't have SCD to see if their hearts react the same way under stress. Primary Objective - To estimate the coronary flow reserve (CFR) (also referred to as myocardial perfusion reserve), as measured by PET stress-rest myocardial perfusion imaging, in SCD patients with and without diastolic dysfunction, and healthy controls. Secondary Objectives - To investigate the relationship between decreased CFR (quantified with PET stress- rest myocardial perfusion imaging) and presence of abnormal diastolic parameters
Patients with sickle cell disease suffer from acute and chronic pain that diminishes their quality of life. The purpose of this study is to assess the feasibility and acceptability of mindfulness meditation, breathing exercises, and gentle yoga therapy as supportive measures for the management of acute vaso-occlusive pain crises in the inpatient setting.
