Complement-mediated granulocyte dysfunction in paroxysmal nocturnal hemoglobinuria.
In paroxysmal nocturnal hemoglobinuria (PNH), infection, both viral and bacterial, disproportionate to the mild neutropenia seen in many such patients is responsible for significant morbidity. We report impaired granulocyte chemotaxis efficiency which may contribute to the problems induced by bacterial infections. PNH (but not normal) granulocytes, after exposure to very small concentrations of...
متن کاملComplement C3dg-mediated erythrophagocytosis: implications for paroxysmal nocturnal hemoglobinuria.
The clinical management of paroxysmal nocturnal hemoglobinuria (PNH), a rare but life-threatening hematologic disease, has fundamentally improved with the introduction of a therapeutic that prevents complement-mediated intravascular hemolysis. However, a considerable fraction of PNH patients show insufficient treatment response and remain transfusion dependent. Because the current treatment onl...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematologic disorder that manifests with hemolytic anemia, thrombosis, and peripheral blood cytopenias.Acute abdominal pain is one of the PNH clinical manifestations due to venous thrombosis of intra-abdominal sites including hepatic, portal, mesenteric, and splenic veins.Eculizumaband allogeneic bone marrow transplantation (BMT) arethe only w...
متن کاملParoxysmal nocturnal hemoglobinuria.
Paroxysmal Nocturnal Hemoglobinuria (PNH) literally means to have episodes of hemoglobin in the urine during the night. It is a Coomb's negative rare hemolytic disorder characterized by non-malignant clonal expansion of haemopoietic stem cells due to acquired genetic mutations. A 30 years old male patient presented with 5 years history of transfusion dependent anemia with intermittent episodes ...
متن کاملCharacterization of the complement sensitivity of paroxysmal nocturnal hemoglobinuria erythrocytes.
The affected erythrocytes of paroxysmal nocturnal hemoglobinuria (PNH II and PNH III cells) are abnormally sensitive to complement-mediated lysis. Normal human erythrocytes chemically modified by treatment with 2-amino-ethylisothiouronium bromide (AET) have been used as models for PNH cells inasmuch as they also exhibit an enhanced susceptibility to complement. To investigate the bases for the ...
