Many patients with Sickle Cell Disease (SCD) may develop Acute Chest Syndrome (ACS). ACS is usually caused by a Lower respiratory tract infection (LRTI) which may be caused by either a bacterium or a virus. Antibiotics are usually used for 7 to 10 days with no microbiological workup. We hypothesize that the identification of the microorganisms might lead to a reduction of antibiotics exposure and a better care of the patients. We speculate that an early pathogen-directed strategy (respiratory broad panel multiplex PCR and early antibiotics interruption based on the PCT values decrease) might reduce the antibiotics exposure in SCD patients with ACS who are hospitalized and for whom an antibiotic treatment is indicated, as compared with usual care
As part of routine care for SCD, some people are found to have low oxygen levels (≤ 88%) while sleeping, at rest, or with exercise. Testing is done with a small portable device positioned on the finger that measures oxygen levels during sleep, at rest, or following exercise. The investigators start oxygen treatment for people with low levels of oxygen. As a part of this study, the investigators will find out if any changes in cell "stickiness" occur with low oxygen levels (at rest, at night, or with exertion) and if cells become "less sticky" with oxygen treatment. Study subjects will be seen before testing and 2 months after testing. In some cases (people with low oxygen levels during testing), study subjects will have been prescribed oxygen, and the investigators will test the effects of that treatment on the stickiness of red cells.
The purpose of this study is to determine if a search strategy of searching for an HLA-matched unrelated donor for allogeneic transplantation if possible then an alternative donor if an HLA-matched unrelated donor is not available versus proceeding directly to an alternative donor transplant will result in better survival for allogeneic transplant recipients within 2 years after study enrollment.
Improvements of health infrastructure, preventive care and clinical treatment have reduced the morbidity and mortality of sickle cell disease (SCD). However, SCD is still an increasing national health problem, with increase longevity the chronic effect of sustained hemolysis and episodic vaso-occlusive events and the recurrent episodes of ischemic reperfusion injury drive the development of progressive end organ complications and cardiovascular, pulmonary, neurological and renal systems are most commonly affected. Today there is hope for a cure using hematopoietic stem cell transplantation (HSCT). However, at present; the procedure is infrequently performed and very expensive. In this research we will assess the effect of implementation of the automated erythrocytapheresis in the outcome of sickle cell disease in single Egyptian center.
This study objectives to assess the role of endothelial monocyte-activating polypeptide II (EMAP II) as a marker of endothelial dysfunction and disturbed angiogenesis in sickle cell disease and to identify its correlation With the oxidative status.
This study evaluates the safety and feasibility of using high dose topical capsaicin patches for the treatment of neuropathic pain in pediatric patients with sickle cell disease, as well as the feasibility of using a number of tests for the evaluation and monitoring of neuropathic pain. The hypothesis, based on evidence obtained from studies in adults with neuropathic pain related to other diseases as well as a single previously published study of capsaicin in pediatric patients, is that capsaicin will be well tolerated in this population. Additionally, it is hypothesized that it is feasible to monitor changes in neuropathic pain via the testing listed below.
This is an observational study of medical marijuana manufactured and dispensed by Ilera and given as standard treatment for a variety of approved serious medical conditions as defined by individual state law. All patients who are receiving one of the four formulations (Dream, Soothe, Shine and Ease) of medical marijuana will be provided a study flyer and asked to contact the study team via phone or email. Once the study team confirms eligibility, the study team will meet the subject face-to-face most likely at their dispensary (or other mutually agreeable location) and obtain informed consent, and assent when appropriate. Initial baseline demographic information, medical history and medication inventory will be completed. Also, since it is possible that the Investigators will enroll subjects across the region, Investigators anticipate the need to seek consent over the phone for many patients. This will be done via Skype, Go to Meeting, Facetime or similar platforms so that the Investigators can have a face to face interaction with the potential subjects. Regardless of where this discussion takes place (i.e., in person or via the web), all reasonable safeguards to ensure patient privacy will be taken. Patients or their legally authorized representative (LAR) will be given sufficient (i.e., up to several hours/days) to make a decision to participate in this study. Study staff will fax or email the consent form for their signature and no study procedures will begin until the signed consent form is received by the study team. The subjects or their LARs will be instructed on obtaining the blood samples. Blood draws will be completed in the subjects' home after one of their standard doses is taken.
The study consists in collecting umbilical cord blood cells from newborns at risk of sickle cell disease, to perform laboratory experiments aiming to characterize the cells with HbS/HbS mutation, to develop methods to prepare, to gene-modify and to preserve these cells.
Primary Objective 1. Define the pharmacokinetics of liquid-formulated HU in infants (9 months to <2 years) 2. Assess the relative bioavailability of HU "sprinkles" compared to capsules in children and adolescents (≥2 to 18 years). Secondary Objective Compare PK parameters in infants versus older children on this study and those from our previous "Pharmacokinetics and Bioavailability of a Liquid Formulation of Hydroxyurea in Pediatric Patients with Sickle Cell Anemia" (NCT01506544) trial. Exploratory Objectives Capture information regarding the taste of HU sprinkles using palatability questionnaire. This trial is an open label, single center assessment of the pharmacokinetics of two formulations of hydroxyurea (HU) designed to (1) determine the pharmacokinetic profile of a liquid formulation in infants and to (2) determine the bioavailability of "sprinkles", a novel method of administration for older children. The study aims to generate data to facilitate FDA approval for HU in children and potentially validate a new mode of administration ("sprinkles") that will optimize access and adherence for children in the US and globally.
FT-4202 is an oral small-molecule agonist of pyruvate kinase red blood cell isozyme (PKR) being developed for the treatment of hemolytic anemias. This initial study will characterize the safety, tolerability and the pharmacokinetics/pharmacodynamics (PK/PD) of a single ascending dose and multiple ascending doses of FT-4202 in the context of Phase 1 studies in healthy volunteers and sickle cell disease patients. The effects of food on the absorption of FT-4202 will also be evaluated in healthy volunteers.
