Compared with European series, two points emerge: (1) the disease in Thai affects individuals of younger age group with a tendency to male preponderance; (2) the incidence of arterial and venous thrombosis is relatively rare. In association with aplastic anaemia, two main categories of PNH patients, are described, which differ in their clinical and laboratory citeria. Copyright © 1978, Wiley Blackwell.
