Economic burden of sickle cell disease in Brazil.

Background: Sickle cell disease (SCD) may cause several impacts to patients and the whole society. About 4% of the population has the sickle cell trait in Brazil, and 60,000 to 100,000 have SCD. However, despite recognizing the significant burden of disease, little is known about SCD costs.

[Infectious complications after surgical splenectomy in children with sickle cell anemia disease].

Objective:: To evaluate the frequency of infectious complications in children with sickle cell disease (SCD) after surgical splenectomy for acute splenic sequestration crisis.

Methods:: Retrospective cohort of children with SCD who were born after 2002 and were regularly monitored until July 2013. Patients were divided into two groups: cases (children with SCD who underwent surgical splenectomy after an episode of splenic sequestration) and controls (children with SCD who did not have splenic sequestration and surgical procedures), in order to compare the frequency of invasive infections (sepsis, meningitis, bacteremia with positive blood cultures, acute chest syndrome and/or pneumonia) by data collected from medical records.
