Allogeneic Hematopoietic Cell Transplantation for Paroxysmal Nocturnal Hemoglobinuria

Intestinal perforation in a patient with paroxysmal nocturnal hemoglobinuria

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...

Hematopoietic stem cell transplantation for paroxysmal nocturnal hemoglobinuria: long-term results of a retrospective study on behalf of the Gruppo Italiano Trapianto Midollo Osseo (GITMO).

BACKGROUND Paroxysmal nocturnal hemoglobinuria is an acquired clonal disorder of the hemopoietic stem cells for which the only curative treatment is allogeneic hematopoietic stem cell transplantation. DESIGN AND METHODS The aim of this retrospective study was to assess the long-term clinical and hematologic results in 26 paroxysmal nocturnal hemoglobinuria patients who received hematopoietic ...

Eculizumab before and after allogeneic hematopoietic stem cell transplantation in a patient with paroxysmal nocturnal hemoglobinuria.

Paroxysmal nocturnal hemoglobinuria (PNH) is characterized by the triad of intravascular hemolysis, venous thrombosis, and cytopenia. Treatment of PNH is generally supportive. Bone marrow transplantation is the only curative therapy for PNH, but is associated with significant morbidity and mortality. Herein, we present a patient with PNH that received eculizumab, a humanized monoclonal antibody...

Paroxysmal nocturnal hemoglobinuria with deletion of chromosome 13q (q12q14): a case report and review of the literature.

A normal karyotype is usually present in cases of classic paroxysmal nocturnal hemoglobinuria (PNH), whereas chromosomal abnormalities involving chromosome bands 13q12 to 13q14 (13q12q14) are frequently found in various hematologic malignancies, including chronic lymphoblastic leukemia (CLL) and myelodysplastic syndrome (MDS). Here, we present a case of a 55-year-old male patient with PNH who h...

Recent advances in the pathogenesis and treatment of paroxysmal nocturnal hemoglobinuria

Paroxysmal nocturnal hemoglobinuria (PNH) is a very rare disease that has been investigated for over one century and has revealed unique aspects of the pathogenesis and pathophysiology of a hemolytic anemia. PNH results from expansion of a clone of hematopoietic cells that, as a consequence of an inactivating mutation of the X-linked gene PIG-A, are deficient in glycosylphosphatidylinositol (GP...
