Key clinical point: Older patients with immune thrombotic thrombocytopenic purpura (iTTP) more often have an atypical neurological presentation, which could result in a delayed diagnosis.
Major finding: Time from hospital admission to diagnosis was 3 days for those older patients, versus just 1 day for patient under 60 years of age (P = .0001).
Study details: An analysis of 411 iTTP patients entered into a French registry between 2000 and 2016.
Disclosures: The study was partly funded by a grant from the French Ministry of Health. Study authors reported disclosures related to Alexion, Ablynx (now part of Sanofi), Shire, and Octapharma.
