BACKGROUND The platelet (PLT) Pan Genera Detection test (PGD) is a rapid bacterial detection system used to screen PLTs for bacterial contamination. We report a single center 46-month experience with secondary screening of apheresis PLTs by PGD testing. STUDY DESIGN AND METHODS Existing testing records of apheresis PLTs screened by PGD from July 2008 to(More)
Transplant-associated thrombotic microangiopathy (TA-TMA) is a rare clinical syndrome associated with significant mortality. Although the use of plasma exchange (PE) in TA-TMA continues to be explored, evidence for its efficacy is debated. We performed a single institution, retrospective study to evaluate the efficacy of PE in treating TA-TMA patients.(More)
Thrombotic microangiopathy is a pathological process that results in thrombocytopenia, schistocytes, and organ ischemia. A wide variety of causes of thrombotic microangiopathy have been described, each associated with a different pathological stimulus and predisposition toward certain vascular territories. This review will summarize our understanding of key(More)
Blood can form a gel when there are high concentrations of proteins, such as IgM and/or IgG antibodies, that precipitate at low temperatures (cryoglobulins) or agglutinate red blood cells (cold agglutinins) (1, 2 ). A bone marrow biopsy performed on this patient revealed Waldenström macroglobulinemia, which produces large amounts of IgM (3, 4). Warming this(More)
We studied 35 pediatric patients with autoimmune hemolytic anemia seen at Mayo Clinic from 1994 to 2014. The median age was 10.0 years and 65.7% were males. Most had warm antibodies (80.0%) and some secondary to viral (14.3%) or autoimmune disorders (31.4%). Seven (20.0%) patients presented with Evans syndrome, 3 of whom also had common variable(More)
BACKGROUND Platelet transfusion-refractoriness is a challenging and expensive clinical scenario seen most often in patients with hematologic malignancies. Although the majority of platelet transfusion-refractory cases are due to nonimmune causes, a significant minority are caused by alloimmunization against Class I human leukocyte antigens (HLAs) or human(More)
OBJECTIVE HLA-DPB1 matching may impact allogeneic hematopoietic stem cell transplantation (ASCT) outcomes; however, this locus is not in linkage disequilibrium with the remainder of the HLA genes. After classifying HLA-DPB1 mismatches based on T-cell epitope, avoiding non-permissive mismatches may impact survival. We tested this hypothesis at a single(More)
