PAROXYSMAL NOCTURNAL HEMOGLOBINURIA (PNH) is an acquired disorder in which subpopulations of peripheral blood elements sensitive to autologous compleqent appear in the circulation.'+ 2 Activation of the complement cascade on the surfaces of these cells results in intravascular hemolysis which can be associated with thrombotic phenomena and infectious complications. The abnormal activation occurs as a consequence of inability of the affected cells to regulate the activities of autologous complement proteins deposited on them. The clinical manifestations of PNH are~ ariable.~.~ Hemoglobinuria, often nocturnal and paroxysmal, occurs as a presenting sign in about 50 percent of patients. It can be dramatic or minimal as it depends on the number and type (see below) of affected cells that are generated. Hemosiderinuria, however, is almost always detectable albeit at varying levels. Thrombosis is a leading cause of morbidity or mortality. The thrombotic tendency is characterized by 50-to 100-fold increased sensitivity of affected platelets to thrombin-induced aggregation,'though other factors, such as deficient cell-associated plasminogen activator activity (see below) may be involved. 6 Bacterial or fungal infections occur most frequently late in the course of disease and can be lifethreatening. Although leukopenia while commonly present is usually mild, abnormalities of white cell (WBC) function have been doc~ mented.~.~ These include reduced granulocyte responsiveness to chemotactic factors and decreased expression of adhesion molecule^.^-^ In up to 25 percent of cases, PNH may evolve from or into aplastic anemia and the epidemiology of both con-
