متن کاملParoxysmal nocturnal hemoglobinuria.
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare bone marrow failure disorder that manifests with hemolytic anemia, thrombosis, and peripheral blood cytopenias. The absence of two glycosylphosphatidylinositol (GPI)-anchored proteins, CD55 and CD59, leads to uncontrolled complement activation that accounts for hemolysis and other PNH manifestations. GPI anchor protein deficiency is almost alw...
متن کاملParoxysmal Nocturnal Hemoglobinuria
Paroxysmal nocturnal hemoglobinuria (PNH) is a complex hematological disorder resulting in a quite unique clinical syndrome. In fact, the typical clinical presentation encompasses three distinct hematological manifestations, i.e., hemolytic anemia, bone marrow failure and thrombophilia (Dunn et al 2000; Parker & Ware 2003; Notaro & Luzzatto 2003). Thus, the term PNH covers only one feature of t...
متن کاملThrombosis in paroxysmal nocturnal hemoglobinuria.
The most frequent and feared complication of paroxysmal nocturnal hemoglobinuria (PNH) is thrombosis. Recent research has demonstrated that the complement and coagulation systems are closely integrated with each influencing the activity of the other to the extent that thrombin itself has recently been shown to activate the alternative pathway of complement. This may explain some of the complexi...
