Paroxysmal nocturnal hemoglobinuria PNH is a rare acquired disorder of hematopoietic stem cells. The disease is diagnosed with haemolytic anemia, marrow failure or episodes of venous thrombosis. The diagnosis is based on flow cytometry, which allowed direct quantification of the GPI-AP-deficient cells. From earlier descriptions, the clinical polymorphism of PNH has been recognized by two presentations; one form, predominantly haemolytic without overt marrow failure, referred to classic PNH and the other one, with marrow failure, was often described as the aplastic anemia PNH syndrome AA-PNH.

We'd like to understand how you use our websites in order to improve them. Register your interest. Paroxysmal nocturnal hemoglobinuria PNH is a disease linked to a somatic mutation which is accompanied by expansion of cell clones deficient in molecules needed to make cell membrane anchors for proteins.

These mutations can be found in diverse forms, resulting in differing diagnostic and therapeutic implications. Flow cytometry is the recommended technology for confirming diagnosis and monitoring patients.

However, the technological approach differs according to whether the aim is to diagnose classic PNH Marchiafava-Micheli syndrome or identify one of the sub-populations that can occur in cases of bone marrow failure, where the disease affects PNH cells.

Paroxysmal nocturnal hemoglobinuria PNH is a rare acquired disorder of hematopoietic stem cells. The disease is diagnosed with hemolytic anemia, marrow failure and thrombosis. The two most common sites are hepatic and cerebral veins. These locations are correlated with high risk of death. Currently, these data are balanced with the use of a monoclonal antibody Eculizumab , which has significantly improved the prognosis with a survival similar to general population after 36 months of follow-up. Anticoagulant treatment is recommended after a thromboembolic event but has no place in primary prophylaxis.
