This study aims to investigate the possible efficacy and safety of L-Arginine in children having Sickle Cell Disease with increased Tricuspid Regurgitant Jet Velocity
There has been little progress for effective treatment of pain in sickle cell disease (SCD) patients. Many organizations have recognized that understanding the causes and reducing the burden of pain in SCD is critical in order to improve the quality of life in SCD patients. As patients with SCD face the challenge of living with both acute and chronic pain which is often improperly treated, our translational and interdisciplinary project aims to identify objective measures of pain sensitivity and its biochemical and genetic correlates.
An open-label, single arm study in patients 12 to 21 years of age with SCD to evaluate the effects of etavopivat on cerebral and muscle hemodynamics.
Sickle Cell Disease is a serious disease that is life-threatening for patients being homozygous for the SS form or heterozygous for the SC or βthal forms. The CHU Brugmann hospital currently regularly treats about 70 homozygous adult patients and this number is in constant augmentation.
Sickle cell disease patients may develop a cardiomyopathy due to chronic anemia, the haemosiderosis risk or, less frequently, to coronary vaso-occlusive damages.
pulmonary complications are common in sickle cell disease patients. Respiratory training using inspiratory muscle trainer (IMT) is usually a good choice to improve these complications. Recently, acupuncture like transcutaneous electrical nerve stimulation (AC-tens) may also improve these complications.
The main objective of this study is to evaluate at the national level (France)
* the early healthcare practices for children with sickle cell disease screened at birth,
* the adequacy of theses practices with the national recommendations,
* their variability over time and according the characteristics of treatment centers.
Sickle cell disease is characterized by chronic hemolytic anemia, painful crisis called vaso-occlusive crisis and chronic inflammation. Activated platelets of Sickle cell disease patients participated to both chronic inflammation and painful vaso-occlusive crisis .
The main aim of this study is to characterize the contribution of Nucleotide-binding domain Leucine Rich repeat containing Protein 3 inflammasome in platelets' activation in Sickle cell disease and to connect platelet activation, inflammation and sickle cell disease complication.
This study aims to answer the question whether daily oral vitamin D supplementation can reduce the risk of respiratory or lung complications in children and adolescents with sickle cell disease. Respiratory problems are the leading causes of sickness and of death in sickle cell disease. The investigators hypothesize that daily oral vitamin D3, compared to monthly oral vitamin D, will rapidly increase circulating vitamin D3, and reduce the rate of respiratory complications by 50% or more within the first year of supplementation in children and adolescents with sickle cell disease.
Part 1: A pilot study in patients with homozygous S (HbSS) or hemoglobin S with beta zero thalassemia(HbS-βo thalassemia), with the aim of examining the effect of intravenous NAC treatment on plasma VWF parameters and measures of redox and RBC function.
Part 2: A pilot study in patients with sickle cell disease admitted to the hospital in vaso-occlusive crisis to determine the effects of NAC infusions on plasma VWF parameters and measures of redox and RBC function, and on measures of pain and hospital length of stay.
