Twelve episodes of acute fatty liver of pregnancy (AFLP) were diagnosed in 11 patients during the past 18 years in a general hospital in Santiago, Chile, with a prevalence of 1 per 15,900 deliveries. Acute fatty liver of pregnancy started between the 31st and 38th weeks of pregnancy, with malaise, vomiting, jaundice, and lethargy as the main clinical manifestations. Polydipsia (in nine episodes) and skin pruritus (in seven episodes) were unusual clinical findings. In two patients, pruritus started two and four weeks before AFLP, suggesting that an intrahepatic cholestasis of pregnancy preceded AFLP in those patients. Considering the current prevalence of both diseases in Chile, their association should be considered fortuitous. In another patient, two consecutive pregnancies were affected by AFLP, raising to three the number of reported patients with recurrent AFLP. In 11 episodes, liver biopsies supported the diagnosis of AFLP by showing small and midsized vacuolar cytoplasmic transformation as the most prominent histopathological feature. Positive intracellular fat staining was found in the four samples analysed. Studies by electron microscopy showed megamitochondria with paracrystalline inclusions in four samples. All the mothers survived, but fetal mortality was 58.3%. Several extrahepatic complications delayed maternal recovery for up to four weeks after delivery. This study confirms an improvement in maternal prognosis in AFLP, discusses the possibility of an epidemiological association with intrahepatic cholestasis of pregnancy, and increases the number of patients reported with recurrent AFLP.

Acute fatty liver of pregnancy is a serious complication of the 3rd trimester associated with high rates of maternal-fetal morbidity and mortality. Prompt diagnosis and treatment are essential to achieve optimal maternal-fetal outcomes. Collaboration between critical-care and perinatal nursing staffs is a crucial component of managing patient care. A recent case of acute fatty liver of pregnancy is reported. A team approach resulted in the survival of the patient and the delivery of healthy twins.

We describe a patient in whom acute fatty liver of pregnancy developed after long-term toluene exposure. Acute fatty liver of pregnancy was documented by a liver biopsy specimen stained with oil red O and observed under electron microscopy. Although the mother did well, she gave birth to a stillborn whose autopsy showed visceral congestion and placental infarction. This case raises the hypothesis of a possible relationship between toluene exposure and acute fatty liver of pregnancy.

Acute fatty liver of pregnancy is a rare clinical entity unique to pregnancy that occurs during the third trimester. The obstetric team must be familiar with this disease because early diagnosis and prompt delivery have dramatically improved prognosis, which was often fatal for both mother and child. Clinicians must have a high index of suspicion for this condition when a woman has nausea or vomiting, abdominal pain (particularly epigastric), jaundice, polyuria-polydipsia (without diabetes), increased serum transaminase activity or thrombocytopenia in late pregnancy. The disease rarely recurs during a subsequent pregnancy. The cause is unknown, but some cases of acute fatty liver of pregnancy have been associated with a genetic deficiency of fatty acid beta-oxidation. Because of the possibility of this congenital deficiency, infants of affected mothers should undergo close follow-up from birth.

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.

Acute fatty liver of pregnancy is a rare disease which may be letal if diagnosis is missed. The pathogenesis is not completely clear, but there is some evidence that some cases have been associated with a genetic deficiency of fatty acid beta-oxidation. Other predisposing factors include primiparity, multiple pregnancy, male fetal sex and pre-eclampsia. Clinical presentation and laboratory findings are often unspecific. Increasing serum aminotransferases are characteristic in the early stage of the disease. Liver biopsy establishes the diagnosis and typically shows microvesicular, centrilobular fatty changes of hepatocytes. Differential diagnosis includes the HELLP-Syndrome, cholestasis of pregnancy, pre-eclampsia and viral or drug induced hepatitis. Without adequate treatment liver failure with coagulopathy and encephalopathy may develop. Two cases of acute fatty liver in pregnancy in an early stage are presented. Clinical and histopathological findings as well as diagnostic and therapeutic procedures are discussed.

Acute fatty liver of pregnancy is an uncommon, potentially fatal disorder. Between 1998 and 2000, two patients with acute fatty liver of pregnancy presented at the Christian Medical College Hospital, Vellore. Both patients were in the thirty-sixth week of pregnancy. jaundice and encephalopathy were the predominant symptoms. Both the mothers died after they delivered a stillborn Infant each. The maternal deaths were due to multiorgan failure and/or postpartum haemorrhage and sepsis. The route of delivery was vaginal in both the patients. Extrahepatic and metabolic complications in both cases Included renal failure, sepsis, hypoglycaemia, disseminated intravascular coagulation and gastrointestinal bleeding. Liver biopsy done in both patients was consistent with the diagnosis of acute fatty liver of pregnancy. To the best of our knowledge, this is the first report from India on acute fatty liver of pregnancy.

We describe a case of acute fatty liver that developed during the third trimester of pregnancy. Acute fatty liver of pregnancy (AFLP) is a well-documented medical condition and is important due to its implications on maternal and fetal morbidity and mortality. AFLP is managed with supportive care and close surveillance is needed in patients with a previous history of this disease. Long-term sequelae such as brain damage may also occur. This case was unusual because the patient presented due to a co-incident uterine scar rupture and was subsequently diagnosed with AFLP. Although no association between scar rupture and AFLP has been reported in the scientific literature, the association of abdominal scar dehiscence and liver disease has been reported previously.

Acute fatty liver of pregnancy is a rare clinical syndrome of pregnancy that occurs during the third trimester. Clinicians must have a high index of suspicion for this condition when a woman has nausea or vomiting during the last trimester. Early diagnosis and prompt delivery improve foetal and maternal prognosis. We report a case of a previously healthy 23-year-old woman who presented an acute fatty liver of pregnancy with intrauterine fetal death. Based on this experience as well as on medical literature, characteristics of this uncommon pathology are discussed.

Abnormal liver tests occur in 3%-5% of pregnancies, with many potential causes, including coincidental liver disease (most commonly viral hepatitis or gallstones) and underlying chronic liver disease. However, most liver dysfunction in pregnancy is pregnancy-related and caused by 1 of the 5 liver diseases unique to the pregnant state: these fall into 2 main categories depending on their association with or without preeclampsia. The preeclampsia-associated liver diseases are preeclampsia itself, the hemolysis (H), elevated liver tests (EL), and low platelet count (LP) (HELLP) syndrome, and acute fatty liver of pregnancy. Hyperemesis gravidarum and intrahepatic cholestasis of pregnancy have no relationship to preeclampsia. Although still enigmatic, there have been recent interesting advances in understanding of these unique pregnancy-related liver diseases. Hyperemesis gravidarum is intractable, dehydrating vomiting in the first trimester of pregnancy; 50% of patients with this condition have liver dysfunction. Intrahepatic cholestasis of pregnancy is pruritus and elevated bile acids in the second half of pregnancy, accompanied by high levels of aminotransferases and mild jaundice. Maternal management is symptomatic with ursodeoxycholic acid; for the fetus, however, this is a high-risk pregnancy requiring close fetal monitoring and early delivery. Severe preeclampsia itself is the commonest cause of hepatic tenderness and liver dysfunction in pregnancy, and 2%-12% of cases are further complicated by hemolysis (H), elevated liver tests (EL), and low platelet count (LP)-the HELLP syndrome. Immediate delivery is the only definitive therapy, but many maternal complications can occur, including abruptio placentae, renal failure, subcapsular hematomas, and hepatic rupture. Acute fatty liver of pregnancy is a sudden catastrophic illness occurring almost exclusively in the third trimester; microvesicular fatty infiltration of hepatocytes causes acute liver failure with coagulopathy and encephalopathy. Early diagnosis and immediate delivery are essential for maternal and fetal survival.
