Different retrospective studies in conditions with accelerated platelet clearance, such as anti-GPIb antibody-mediated ITP [22,23] or suspected influenza [24], and an open-label randomized trial in sepsis [26], have supported the notion that Neu-1 inhibition by oseltamivir increases platelet counts. The gene discussed is NEU1; the disease is autoimmune thrombocytopenic purpura.
