Active clinical trials for "Anemia, Sickle Cell"

Our goal is to improve the self-management of pain and stress in adult outpatients with sickle cell disease (SCD) by determining the feasibility of a self-managed guided relaxation (GR) stress reduction intervention using a tablet-based mobile device. Currently, opioid analgesics are primarily used to treat SCD pain while self-managed behavioral modalities such as GR, are rarely used. Little is known about the effects or mechanisms of GR on pain and stress, in adults with SCD. Emerging evidence from the hypothalamic pituitary adrenal (HPA) axis theory offer insights for understanding the mechanisms. Adding GR as a supplement to analgesic therapies will address the paucity of self-management strategies for controlling pain in SCD. GR is a simple and cost-effective non-drug intervention that could reduce pain and stress in outpatients with SCD. GR is an intervention where outpatients with SCD are directed to listen to and view audio-visual recordings while they visualize themselves being immersed in that scene.

The project will test a tailored web and smartphone-based application (iCanCope with SCD) to improve pain self-management and functioning in youth (aged 12-18) with sickle cell disease. The program will include goal setting, peer-based social support, and pain self-management training. The investigators will determine initial program effectiveness through a pilot three-site randomized controlled trial in 160 youth randomized to treatment compared to attention control.

Acute chest syndrome (ACS) is similar to severe pneumonia and is a common cause of hospitalizations for people with sickle cell disease (SCD). Blood transfusions are one treatment option for ACS. High levels of an enzyme called secretory phospholipase A2 (sPLA2) may be present in people before they develop ACS. This study will determine how well sPLA2 levels can predict the onset of ACS and whether identifying high sPLA2 levels allows enough time to prevent ACS with blood transfusions. Results from this study will help to determine the feasibility of conducting a larger study that would further examine the use of sPLA2 levels and blood transfusions to prevent ACS in people with SCD.

Acute chest syndrome is a severe sickle cell disease complication in children requiring blood transfusion therapy to prevent acute respiratory failure and death. Nitric oxide is a potent vasodilator that could reverse pulmonary vascular occlusion and restore normal oxygenation. The randomized trial will test that hypothesis.

This study tests the clinical outcomes of one of two preparative regimens (determined by available donor source) in patients with non-malignant hemoglobinopathies. The researchers hypothesize that these regimens will have a positive effect on post transplant engraftment and the incidence of graft-versus-host-disease. Regimen A2 has replaced Regimen A in this study. Two patients were treated on Regimen A but did not have evidence of initial engraftment thus triggering the stopping rule for that arm of this study.

The purpose of this research is to evaluate the effects of L-glutamine as a therapy for sickle cell anemia and sickle ß0-thalassemia. as evaluated by the number of occurrences of sickle cell crises.

The purpose of this study is to determine if the new orally active iron chelator, ICL670, is as safe as deferoxamine in preventing accumulation of iron in the body while a patient is undergoing repeated blood transfusions.

ICA-17043 is being developed for the chronic treatment of patients with sickle cell disease (SCD) in both adults and children. ICA-17043 is a potent and specific inhibitor of a channel in human red blood cells (RBCs) that blocks RBC dehydration. ICA-17043 is expected to inhibit RBC dehydration and thus should prevent or delay the sickling process. By reducing sickled cells, an improvement in anemia, a reduction in painful crises, and ultimately, less end-organ disease is anticipated.

OBJECTIVES: I. Evaluate the efficacy and tolerability of fructose administered every 6 hours for up to 72 hours to patients in active sickle cell crisis. II. Obtain tolerability information in selected patients treated with fructose for more than 72 hours.

This is a study to determine if oral arginine will increase nitric oxide in sickle cell disease (SCD) patients with acute chest syndrome (ACS). It will also assess the effects of arginine in the body and how the body uses nitric oxide in ACS.
