Active clinical trials for "Anemia, Sickle Cell"

This study compares the clinical tablet formulation of prasugrel taken orally with an orally disintegrating tablet (ODT) taken orally. The study will evaluate the amount of prasugrel active metabolite circulating in the blood for each treatment.

Sickle cell disease (SCD) is one of the most common inherited diseases worldwide and exhibits highest frequency in people of African descent. Patients with SCD currently have few treatment options, with hydroxyurea being the only medication approved to reduce the frequency of vaso-occlusive crisis (VOC) and prevent other SCD complications such as acute chest syndrome. Once patients develop VOC, hospitalizations aim to alleviate pain; no specific therapy is currently available to otherwise affect the course of the VOC. However, there has been increasing interest in the role of coagulation in the pathogenesis of SCD. The investigators hypothesize that low dose anticoagulant therapy, such as prophylactic dose low-molecular-weight heparin (LMWH), could be a novel way to ameliorate the vaso-occlusive process and thereby hasten the resolution of pain.

This study will test the hypothesis that Heart Rate Variability Biofeedback (HRV-B) restores autonomic balance and reduces pain and other symptoms among patients with sickle cell disease (SCD).The specific aims of this study are to: (1) conduct a randomized, wait list controlled, pilot intervention trial to determine whether HRV-B increases HRV coherence among SCD participants (minimum N of 30, up to 50 total); (2) determine whether HRV-B reduces pain, stress, fatigue, depression or insomnia among SCD participants; and (3) determine whether increases in HRV coherence are associated improvements in pain, stress, fatigue, depression, or sleep among study participants.

The purpose of this study is to see whether hematopoietic stem cell transplant (HSCT) patients can consistently eat a diet rich in prebiotics. This type of diet may be helpful in maintaining diversity in the gastrointestinal (GI) system and therefore potentially decreasing risk of other GI problems.

The purpose of this study is to determine the correct prasugrel dosage to be given to children with sickle cell disease (SCD).

To investigate a modified hematopoeitic cell transplantation (HCT) procedure for sickle cell disease that significantly reduces the toxicity of HCT, yet retains its therapeutic benefit.

The objective of this study is to determine if a subject's genetic make-up would affect the treatment response to codeine in subjects with sickle cell disease.

Sickle cell disease (SCD) is the most common inherited blood disorder affecting 80,000 to 90,000 individuals in the United States.[10] There are 13,000 hospital admissions for a sickle cell crises, costing $448 million dollars annually.[10] In our hospital, the sickle cell population is known to have some of the longest length of stays. Between October 2014 and September 2015, there were 89 admissions for a vaso-occlusive crisis with an average length of stay of 6 days and 12 admissions greater than 10 days and 5 admissions greater than 20 days. We propose to evaluate the feasibility of the new CPP in a pilot randomized control trial to determine if pain and length of stay can be reduced in patients with sickle cell disease. We also propose to evaluate a sleep regimen to determine if this can reduce the hospital stay and help with pain. We hypothesize increased physical activity and proper sleep, as implemented in the CPP, are correlated with decreased hospital length of stay and decreased pain. Additionally, we believe that creating a standardized nighttime environment at the hospital will help the children stay in their circadian rhythm thus promoting improved sleep and a more effective inpatient disease management.

Despite the fact that obstructive sleep apnoea (OSA) is highly prevalent in the sickle cell population, studies focusing on the associations of the two diseases and their common pathophysiological mechanisms are scarce. OSA is one of the most common conditions responsible for hemoglobin desaturation. The nocturnal hemoglobin desaturation occurring in some sickle cell disease (SCD) patients with OSA could trigger hemoglobin S polymerization and red blood cell (RBC) sickling, leading to further blood rheological alterations, hence increasing the risks for VOC. Moreover, OSA has been demonstrated to increase oxidative stress and inflammation in non Sickle Cell Disease (SCD) patients, which, in SCD patients, could increase the risk for complications. Finally, OSA is accompanied by impaired vascular function and autonomic nervous system dysfunction in the general population. Indeed, the presence of OSA in SCD could increase the clinical severity of patients and the frequency of VOC.

Acute chest syndrome (ACS) is a frequent complication of sickle cell disease and is diagnosed by having findings on a chest x-ray and one of the following: chest pain, fever, or trouble breathing. Patients with Acute Chest Syndrome can get very sick and require an exchange transfusion (special large blood transfusion) and mechanical ventilation. Bi-level Positive Airway Pressure (also known as BLPAP or BiPAP) is a device that blows air into a patients lungs via a mask that covers the nose. The goal of this study is to determine whether giving children BiPAP when they have ACS, in addition to providing standard clinical care for ACS, alters the clinical course of these patients. The investigators hypothesize that patients receiving effective BiPAP will have milder clinical courses resulting in shorter hospital stays and fewer transfers to the intensive care unit and exchange transfusions.
