title: Acute fatty liver in the second trimester of pregnancy.
abstract: Objective: Acute fatty liver of pregnancy (AFLP) is an uncommon, potentially fatal disorder that usually occurs in the late third trimester of pregnancy. We present the first reported case of acute fatty liver in the second trimester of pregnancy.Methods: We report the clinical and laboratory findings in a patient with AFLP who presented in the second trimester of pregnancy.Results: A 37-year-old G5P4 woman presented at 22 weeks gestation (by 18 weeks ultrasound) with nausea and vomiting. She was normotensive, had no proteinuria, had elevated SGOT and SGPT (266 and 261, respectively), negative hepatitis studies and a normal platelet count. She was managed conservatively for presumed cholelithiasis until 24 weeks gestation when she was transferred to our facility because of worsening SGPT and SGPT (368 and 505, respectively), jaundice (total bilirubin of 8.9 mg/dL), hypoglycemia, and laboratory evidence of disseminated intravascular coagulation (DIC) (PT = 18.6, PTT = 56, hypofibrinogenemia and presence of fibrin split products). Ultrasound showed singleton fetus (EFW 450 g) with total placenta previa. Computed tomography scan of the abdomen revealed decreased hepatic density consistent with AFLP. Delivery of a nonviable fetus was effected after transfusion of fresh frozen plasma. Postoperatively, the patient had rapid resolution of DIC, jaundice, and hypoglycemia; liver transaminases normalized 5 days postoperatively and the patient was discharged home in good condition 5 days later.Conclusion: It has been traditionally stated that AFLP occurs in the late third trimester of pregnancy. This case demonstrates that, even in the second trimester of pregnancy, the diagnosis of AFLP should be considered as a cause of deteriorating liver function, jaundice, and DIC.
