Acute fatty liver of pregnancy: the hepatologist's view.
Acute fatty liver of pregnancy is a rare clinical entity unique to pregnancy that can lead to hepatic failure and encephalopathy and, if the diagnosis is delayed, to death for the baby and the mother. The characteristic histological picture demonstrates microvesicular fatty infiltration of hepatocytes. Acute fatty liver of pregnancy is a disease of the third trimester of pregnancy. The most significant clinical findings are nausea or vomiting, abdominal pain, jaundice, hepatic encephalopathy, increased transaminase levels, decreased platelet count, increased prothrombin time, and renal failure. Hypertension and proteinuria are common. Liver biopsy is not always necessary for diagnosis but may be useful in atypical cases. The primary therapy is early delivery and supportive care. Both the obstetric team and the medical consultants must have a high index of suspicion for this disease because early delivery is lifesaving and has transformed the prognosis for the mother and the baby. Collaboration between obstetricians and gastroenterologists is necessary to make the diagnosis and also to improve our understanding of this disease of unknown etiology.
