NHLBI TOPMed: REDS-III Brazil Sickle Cell Disease Cohort (REDS-BSCDC)

phs001468.v2.p1dbGapdbGap FHIR

Description

Establishing a Brazilian Sickle Cell Disease Cohort and Identifying Molecular Determinants of Response to Transfusions, Genetic Determinants of Alloimmunization, and Risk Factors Associated with HIV Infection. The REDS-III Brazil SCD Cohort study focused on transfusion practices and predictors of health outcomes in patients with Sickle Cell Disease (SCD) and began in the Fall of 2013. The four primary aims of this study are: 1) Aim A - Establish a cohort of SCD patients with a comprehensive centralized electronic database of detailed clinical, laboratory and transfusion information, as well as establish a repository of blood samples to support biological studies relevant to SCD pathogenesis and transfusion complications; 2) Aim B - Characterize changes in markers of inflammation in response to transfusion by analyzing chemokine/cytokine panels in serial post transfusion specimens; 3) Aim C - Identify single nucleotide polymorphisms (SNPs) that contribute to the risk of red blood cell alloimmunization in SCD by performing a genome-wide association (GWA) study in transfused SCD patients; and, 4) Aim D - Characterize risk of HIV and HIV outcomes in the Brazilian SCD population and compare SCD outcomes among HIV sero-positive and sero-negative SCD patients. Patients are enrolled from six hospitals affiliated with the participating four REDS-III Brazil hemocenters.
