Haploidentical bone marrow transplant with post-transplant cyclophosphamide plus thiotepa improves donor engraftment in patients with sickle cell anemia: results of an international learning collaborative

Sickle cell disease (SCD) has evolved from a life-threatening condition in early childhood, to a chronic disease in adults [1,2]. Improved supportive care [3], use of hydroxyurea therapy [4], and regular blood transfusion therapy for primary [5] and secondary [6] stroke prevention, have resulted in improved childhood clinical outcomes and survival. Approximately 99% of all children born in high resource countries with SCD are expected to live to adulthood [7,8]. The most feared complication in children with SCD is stroke [9].

CONCLUSIONS: Arterial remodeling due to SCA is mediated by JNK signaling, cathepsin proteolytic upregulation, and degradation of elastin and collagen. Demonstration in Townes mice establishes their utility for mechanistic studies of arterial vasculopathy, related complications, and therapeutic interventions for large artery damage due to SCA.

AbstractSickle cell anemia (SCA) pathophysiology is characterized by the activation of sickle red blood cells, reticulocytes, leukocytes, platelets, and endothelial cells, and with the expression of several inflammatory molecules. Therefore, it is conceivable that variations in levels of proinflammatory cytokines may act as a signaling of differential clinical course in SCA. Here, we evaluated the clinical impact of proinflammatory cytokines interleukin 1- β (IL-1β), interleukin 6 (IL-6), and interleukin 8 (IL-8) in 79 patients with SCA, followed in a single reference center from northeastern Brazil. The main cli...

Sickle cell anemia is a unique disease dominated by hemolytic anemia and vaso-occlusive events. The latter trigger a version of ischemia/reperfusion (I/R) pathobiology that is singular in its origin, cyclicity, complexity, instability, perpetuity, and breadth of clinical consequences. Specific clinical features are probably attributable to local I/R injury (e.g., stroke syndromes) or remote organ injury (e.g., acute chest syndrome) or the systematization of inflammation (e.g., multifocal arteriopathy). Indeed, by fashioning an underlying template of endothelial dysfunction and vulnerability, the robust inflammatory systema...

Demystifying Medicine Lecture Series Although the fundamental molecular pathophysiology of sickle cell anemia was elucidated in studies of this genetic disease starting more than 70 years ago, it is only in about the last two decades that this knowledge has led to specific therapies. Indeed in the last decade serious attention has turned to the possibility of a genetic cure of this condition. Have we finally cured sickle cell anemia? Not quite, but we may be on the cusp. Really. In a dozen clinical trials planned or underway, some at the NIH Clinical Center, researchers are applying gene therapy to cure this well-studied g...

The objective of this study is to reduce the morbidity of children with homozygous sickle cell disease presenting severe forms. We have conducted a longitudinal study between November 2015 and September 2017 at the Brazzaville University Hospital. Children with sickle cell disease requiring treatment with hydroxyurea were included. The variables studied were therapeutic compliance, evolutive profile of nutritional status, indications of hydroxyurea, electrophoresis of hemoglobin, blood count, and toxicity. The statistical test used was Student test with a significance threshold of less than 0.05. One thousand twe...

Conclusion: Our findings suggest that hydroxyurea is safe and may prevent silent stroke and stroke in sickle cell disease. More high-quality studies including RCTs are needed.

This study was carried out to compare the fetomaternal outcome in patients with SCD with those without SCD. This was a retrospective cohort study done in the Eastern Province of Saudi Arabia in a tertiary care, teaching hospital, by retrieving the data through the code ICD-9 for SCD, the control group was also selected with comparable characteristics. A total of 302 SCD pregnant patients were included for comparison with 600 pregnant women without SCD as control, during the period of Jan 1, 2008 to December 31, 2018. After the data retrieval, percentages of complications were calculated between the study and control groups...
