Leptospirosis in pregnancy with pathological fetal cardiotocography changes

We report the case of a 33-year-old primigravida who presented at 37 weeks of gestation with symptoms suggestive of acute fatty liver of pregnancy, but was later diagnosed with leptospirosis (i.e. Weil''s disease or syndrome) on serological testing. Cardiotocography showed fetal distress, and an emergency Caesarean section was performed. A healthy neonate with no evidence of congenital leptospirosis was delivered. The patient was treated with intravenous ceftriaxone and discharged well 13 days after admission. Herein, we discuss the patient''s clinical presentation and the cardiotocography changes observed in leptospiral infection, and review the current literature.
