Dig Dis Sci. 2019 Feb 28;: Authors: Koslowsky B, Sadeh C, Grisaru-Granovsky S, Miskin H, Goldin E, Bar-Gil Shitrit A Abstract INTRODUCTION: Thiopurine exposure throughout pregnancy in patients with inflammatory bowel diseases (IBD) is common and teratogenically safe. Late consequences of in utero exposure to thiopurines and its metabolite, 6-thioguanine nucleotides (6-TGN), such as neonatal and infant anemia are still disputed. AIM: To evaluate whether 6-TGN exposure during pregnancy influences anemia in…
