Case Report: Possible Paroxysmal Nocturnal Hemoglobinuria with Pronounced Pancytopenia, Reticulocytopenia, and without Hemoglobinuria Simulating Aplastic Anemia

Aplastic Anemia and Paroxysmal Nocturnal Hemoglobinuria: Search

The association of paroxysmal nocturnal hemoglobinuria (PNH) and aplastic anemia (AA) raises the yet unresolved questions as to whether these two disorders are different forms of the same disease. We compared two groups of patients with respect to cytogenetic features, glycosylphosphatidylinositol (GPII-linked protein expression, protein C/ protein Slthrombomodulinlantithrombin 111 activity, an...

Acquired aplastic anemia and paroxysmal nocturnal hemoglobinuria: studies on clonality.

We used X-chromosome methylation patterns to study clonality in aplastic anemia (AA) and paroxysmal nocturnal hemoglobinuria (PNH). AA is usually not considered to be a clonal stem cell disorder, although this has not been directly investigated. PNH is generally assumed to be a clonal disorder, although there is contradictory evidence. Methylation analysis was performed on DNA from separated gr...

Paroxysmal 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 ...
