Stem cell transplantation for paroxysmal nocturnal haemoglobinuria in childhood

Paroxysmal nocturnal haemoglobinuria (PNH) is a clonal haematopoietic disorder characterized by chronic or intermittent intravascular haemolysis, variable cytopenia and an increased risk of thrombosis. Stem cell transplantation (SCT) is a curative therapeutic option, but its risks must be carefully weighed against the natural course of PNH. World-wide experience with SCT for PNH in the paediatric age group is scarce. We report on two adolescents suffering from PNH with life-threatening complications who were successfully transplanted from unrelated donors. Indications and techniques of SCT in childhood PNH are discussed and an overview of the literature is given.
