Bleeding risk, treatment thresholds and the role of observation
Immune thrombocytopenia (ITP) is an acquired immune-mediated reduction in platelets. It causes bruising, petechiae and sometimes mucosal or intracranial bleeding. Diagnosis is clinical and excludes other causes. Treatment depends on bleeding severity and platelet count, and may include observation, corticosteroids, intravenous immunoglobulin, anti-D and newer agents.

ITP is diagnosed after excluding other causes of thrombocytopenia. Blood counts, peripheral smear, coagulation screen, infection and drug review, and autoimmune screening are part of the assessment. Bone marrow examination is reserved for atypical features, older patients or suspected marrow disease. Bleeding severity, not the platelet number alone, guides urgency.
Asymptomatic patients with moderate counts may be observed. Treatment is considered for significant bleeding or very low counts. First-line options include corticosteroids and intravenous immunoglobulin; anti-D may be used in selected Rh-positive patients. Persistent or chronic ITP may require thrombopoietin receptor agonists, rituximab or splenectomy in selected cases. Urgent management is needed for severe bleeding.
