Immune Thrombocytopenia Purpura was an existing RCH CPG that has been revised then reviewed by the CPG Committee. It will be considered for PIC endorsement on 18 June.

Key Points

1. Immune thrombocytopenia (ITP) is an isolated low platelet count of < 100 x 109/L in a well child with an otherwise normal full blood count (FBC) and film
2. Alternate causes for petechiae and purpura need to be excluded
3. The decision to treat a child should be based on clinical symptoms and not the platelet count; the majority do not require treatment
4. The risk of intracranial haemorrhage in ITP is very low (<1%)
