Immune thrombotic thrombocytopenic purpura in patients over 60 years of age: Diagnostic pitfalls and treatment strategy.

Real-world registry studies of older patients with iTTP highlight diagnostic difficulties in comparison to patients less than 60 years of age with greater risk of renal injury, atypical neurological features and less profound cytopenia, which can result in diagnostic delays. However, there is no clear signal of significantly increased toxicity from full active treatment. Commentary on: Gómez-Seguí et al.
