Important information for investigators of Registry II:

If you are a physician participating in Registry II and you are interested in participating in the PARC-ITP registry, please continue to send in the follow-up forms of Registry II patients for 24 months, as it is very important to have this data. All newly diagnosed ITP patients may be registered prospectively in the PARC-ITP database, which means that some centers will possibly be submitting patient data to both registries, until the follow-ups of Registry II are completed. No data of the same patient should be entered to both Registry II and PARC-ITP. New centers are encouraged to participate in the PARC-ITP registry.
