Aspirin rechallenge in an adult patient previously diagnosed with Reye syndrome

PURPOSE: Aspirin has been the cornerstone of antiplatelet therapy in patients with acute coronary syndromes and is well accepted and recommended by several major healthcare organizations. A combination of aspirin and a P2Y12 inhibitor, commonly known as dual antiplatelet therapy, is recommended in patients with coronary stent implantation to reduce the risk of stent thrombosis and ischemic events. SUMMARY: We recently cared for an adult male who presented with an acute coronary syndrome who had a history of Reye syndrome during childhood. During this admission, he was rechallenged with low-dose aspirin for the first time since his diagnosis of Reye syndrome as a child after aspirin therapy. There have been various case reports in children and adults who have been rechallenged with aspirin within days to weeks after the initial diagnosis of Reye syndrome. These reports show mixed results in children and adults regarding the return of Reye syndrome upon aspirin rechallenge shortly after initial aspirin exposure. CONCLUSION: This, to our knowledge, appears to be the first report of a low-dose aspirin rechallenge 30 years later in life in an adult patient with a history of Reye syndrome while receiving aspirin therapy during childhood.
