Paroxysmal Nocturnal Hemoglobinuria (PNH)
Detection of paroxysmal nocturnal hemoglobinuria (PNH) in bone marrow aspirates
Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired condition in which, due to a mutation of the phosphatidylinositol glycan class A gene, hematopoietic cells lack proteins that are normally anchored to the cell surface by glycosylphosphatidylinositol (GPI). Thus, PNH cells show poor expression of surface proteins, such as CD55 and CD59, and dim or absent binding of fluorescently labeled modified aerolysin (FLAER). In clinical diagnostic laboratories, the detection and quantitation of PNH is currently performed by flow cytometry (FC) analysis of peripheral blood (PB) samples.
Hematopoietic Cell Transplantation for Paroxysmal Nocturnal Hemoglobinuria in the Age of Eculizumab.
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired clonal hematopoietic cell disease characterized by the destruction of hematopoietic cells through activation of the complement system with manifestations that can be life-threatening including hemolysis, thrombosis, and marrow failure. Allogeneic hematopoietic cell transplantation (HCT) remains the sole cure for PNH, but eculizumab, a terminal complement inhibitor of C5, has been used to prevent complement-mediated hemolysis in patients with PNH since its approval by the Food and Drug Administration in 2007.
Fatigue, symptom burden, and health-related quality of life in patients with myelodysplastic syndrome, aplastic anemia, and paroxysmal nocturnal hemoglobinuria.
BACKGROUND:
Fatigue is distressing and affects quality of life (QoL) among patients with myelodysplastic syndrome (MDS), aplastic anemia (AA), and paroxysmal nocturnal hemoglobinuria (PNH).
Young Minnesotan Opens Up About Dual Diagnosis and Emphasizes Emotional Wellness
My Diagnosis
In the summer of 2014 I noticed ongoing bruising all over my body. At first, I thought it might have to do with my diet (low iron), but soon I noticed a new kind of mark on my skin, almost having a bulls-eye appearance. By end of summer I knew I had to do something about this.
PNH Patient Travel Assistance Fund
The AAMDSIF PNH Patient Travel Assistance Fund is available to U.S.-based PNH patients for up to $800 in travel assistance per patient, per year, to see a PNH specialist or get a second opinion from a PNH specialist. Grantees will be permitted to travel with one companion utilizing funds from the grant. Grants will be awarded based on the thorough completion of the required application form and the submission of all required documentation.
