The case of a male infant is reported who was born to a woman with schizophrenia treated with non-narcotic psychotropic drugs during pregnancy; he developed severe prolonged thrombocytosis. The platelet count reached 1310 \u00d7 10<jats:sup>9<\/jats:sup>\/l on day 15. This thrombocytosis persisted for three months. The patient was treated with dipyridamole. A bone marrow aspirate showed normal myeloid and erythroid precursors with an increased number of megakaryocytes. Plasma concentrations of interleukin 6 and thrombopoietin were suppressed. No obvious complications from the thrombocytosis occurred, and the platelet count fell to within the upper limit of normal after 3 months of age. This case indicates that thrombocytosis may occur in infants born to mothers treated with non-narcotic psychopharmaceutical drugs during pregnancy. The thrombocytosis in this case may have been induced by factors other than interleukin 6 or thrombopoietin.<\/jats:p>","DOI":"10.1136\/fn.84.3.f198","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T06:40:22Z","timestamp":1027752022000},"page":"F198-F200","source":"Crossref","is-referenced-by-count":11,"title":["Neonatal
