A French study reported an incidence of ITP of 2.9 cases per 100,000 person-years, with peaks in children and in those older than 60 years of age and a higher frequency of ITP in males in these subgroups. ITP showed seasonal variation, with a peak in winter and a nadir in summer. Persistence or chronicity occurred in 36% of children compared with 67% of adults. In adults, 18% of ITP cases were secondary, with malignancy the main cause. [27]
