Prevalence and specificity of red blood cell antibodies in patients transfused in tertiary hospitals in Burkina Faso.

Background: Sub-Saharan African countries face the challenge of immunological transfusion safety that puts many patients at risk of post-transfusion hemolytic reactions. This is because pre-transfusion testing for irregular/unexpected antibodies that helps to prevent these risks are neither universally available nor accessible. The aim of our study was to determine the prevalence of red blood cell alloantibodies and their specificity in patients transfused in Burkina Faso.

[Purple urine bag syndrome (PUBS): about two cases at the Regional University Hospital Center (CHUR) of Ouahigouya].

Purple urine bag syndrome (PUBS) is an uncommon complication of urinary tract infection. It mainly affects elderly patients with constipation, chronic urinary catheter and prolonged bed rest. Several bacteria belonging to two different groups, the group converting indoxyl urinary sulphate into indoxyl and the group alkalizing urine by the production of urease, are associated with it.
