We report the case of a mother who developed fulminant hepatic failure with hypoglycaemia, coagulopathy, Grade III hepatic encephalopathy, two days after the delivery of her fourth child. She had complained of pruritus for the final two weeks of pregnancy. She received supportive medical management within a critical care unit, and the hepatic failure resolved completely within 48 hours. Liver biopsy confirmed the diagnosis of acute fatty liver of pregnancy. This case is unusual in that this patient deteriorated markedly following delivery, at a time when spontaneous recovery is normally expected.

During the 26th week of a first pregnancy, a 25-year-old woman presented with pruritus suggesting an intrahepatic cholestasis of pregnancy. The pruritus, however, persisted despite the premature delivery of a normal newborn at the 35th week. Moreover, aspartate aminotransferase activity increased, reaching a maximum of 38 times normal level on the 17th day after the delivery. Thus, an acute fatty liver of pregnancy was suspected and confirmed by liver biopsy. This patient appeared to have both intrahepatic cholestasis of pregnancy and acute fatty liver of pregnancy, an association not previously reported. It is suggested that intrahepatic cholestasis of pregnancy caused premature delivery, which in turn may have prevented the onset of severe maternal and fetal complications caused by acute fatty liver of pregnancy.

The occurrence of hepatobiliary disease with or without jaundice during pregnancy provides both the hepatologist and obstetrician with an interesting and urgent diagnostic challenge. Advances in our understanding and management of liver disorders unique to pregnancy and hepatobiliary disease in general have resulted in a significant improvement in the outcome for both mother and fetus. Certain disorders such as acute fatty liver of pregnancy and hepatic haemorrhage associated with toxaemia should be considered medical emergencies and delay in diagnosis of these conditions will probably adversely affect maternal and fetal outcome. A careful clinical history, physical examination, appropriate laboratory tests and radiological investigations should allow a diagnosis within 24-48 hours of presentation. Liver biopsy is rarely required. A careful history may provide important information. Does the patient have pre-existent liver disease? Has there been contact with hepatitis, intravenous drug abuse or any other factor predisposing to acute viral hepatitis? Does the patient have a family history of pruritus and/or jaundice to suggest intrahepatic cholestasis of pregnancy? Is the patient's alcohol consumption excessive? Has the patient received any hepatotoxic medications? Has there been abdominal pain and/or fever to suggest gallstones, hepatic bleeding or acute fatty liver of pregnancy? Laboratory investigations may give valuable diagnostic clues. Marked aminotransferase elevation would suggest acute viral or 'ischaemic' hepatitis. Haematological features of microangiopathic haemolysis would point towards toxaemia or AFLP. Hepatitis A and B serological tests may be helpful in viral liver disease. Radiological investigations may be indicated depending on the clinical context. Abdominal ultrasonography may be useful in the diagnosis of gallstones, biliary obstruction, liver tumours or intrahepatic bleeding. Fatty infiltration of the liver may be diagnosed by ultrasonography but computed tomography (CT) of the abdomen is probably more reliable for a diagnosis of acute fatty liver of pregnancy as it allows measurement of liver density which is typically reduced by fatty infiltration. CT scanning is also probably more valuable than ultrasound in assessing the extent of capsular rupture and haemorrhage into the liver and peritoneal cavity.

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.

In distinguishing normal from abnormal hepatic changes, the author described the expected changes in liver tests that occur during complicated pregnancy. This article reviews the forms of pre-existing liver disease that may affect or be affected by pregnancy, as well as liver diseases that tend to arise during pregnancy. Among the pre-existing liver diseases are autoimmune chronic active hepatitis, which may be activated by pregnancy and tends to be associated with an increased risk of still and premature births. Worsening of chronic hepatitis B and C has occasionally been observed. While some women with cirrhosis can sustain a normal pregnancy without any worsening of hepatic function, others develop liver failure; plus, women with cirrhosis are less fertile and have higher rates of both stillbirths and premature infants. Other liver disorders that may or may not be affected by pregnancy include Dubin-Johnson syndrome, Gilbert syndrome, benign recurrent intrahepatic cholestasis, Wilson's disease, hepatic adenomas, and focal nodular hyperplasia. Among the hepatic disorders that occur during pregnancy in normally healthy women and then resolve after delivery is intrahepatic cholestasis of pregnancy (also known as pruritus gravidarum, recurrent intrahepatic cholestasis of pregnancy, and obstetric hepatosis). Others include acute fatty liver of pregnancy and HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count), which may be part of the spectrum of disorders associated with pre-eclampsia/eclampsia. Pregnancy may also trigger the dissemination of herpes infection to the liver.

The liver has a central role in the metabolism of many drugs, since this organ is the main site of biotransformation of endo- and xenobiotics. Water-soluble drugs have a small volume of distribution and can be eliminated unchanged in the urine. By contrast, lipid-soluble drugs have a larger volume of distribution and require conversion to water-soluble metabolites for their elimination in urine or bile. The liver with its specific receptors, transporters and enzymes is responsible for the uptake, transformation and excretion of the lipophilic drugs. While most of the drugs are transformed into stable metabolites, other drugs form reactive, potentially toxic, metabolites producing liver cell damage. Liver injury caused by drugs may mimic almost any kind of liver disease. Clinical findings are gastrointestinal symptoms with nausea, vomiting and abdominal pain, cholestatic liver injury with jaundice and pruritus of severe inflammatory and cirrhotic liver damage with signs of liver failure, encephalopathy and cerebral edema. The morphological changes vary from hepatitis, cholestasis, fatty liver, granulomatous hepatitis, peri-/portal inflammation, to fibrosis with cirrhotic alterations and vascular lesions and tumors. The most commonly used drugs causing severe liver injury are discussed in detail. These are anabolics, oral contraceptives, antituberculous and antifungal agents, nonsteroidal anti-inflammatory drugs, ring substituted amphetamins ("designer drugs"), antiarrhythmics and antibiotics.

Transaminase level elevation during pregnancy should be viewed as abnormal and evaluated. A high index of suspicion for acute fatty liver of pregnancy should be maintained during the third trimester, since early delivery has radically transformed the maternal and fetal prognosis of this condition. Pruritus is the main symptom of intrahepatic cholestasis, which carries a risk for the fetus. Urinary tract infection can cause cholestasis or worsen intrahepatic cholestasis of pregnancy. In patients with preeclampsia, rapid delivery should be considered if there is evidence of HELLP syndrome. Patients with mild chronic viral hepatitis can usually carry a pregnancy to term without undue difficulty. Neonates born to HBsAg-positive mothers should receive HBV-Ig and vaccine at birth to prevent perinatal transmission of the HBV. In patients with chronic hepatitis C, serum transaminase levels often return to normal during pregnancy, although the virus remains detectable in the blood. Mother-to-infant transmission of the HCV is possible but fairly uncommon if the mother is HIV-negative.

Alcohol-induced diseases of the liver, such as fatty liver, hepatitis and cirrhosis with the potential development of hepato-cellular carcinoma can cause many effects on the skin. Even though they are not caused by excessive alcohol alone, but also by other diseases of the liver or other diseases of internal organs, an experienced person will be able to carry out specific diagnostic procedures. Skin symptoms due to liver diseases include 1. Vascular changes, such as spider nevi, teleangiectasias and palmar erythema. 2. Nail changes, particularly white nails. 3. Changes of the mucous membranes, i.e. glossy tongue. 4. Changes due to altered hormones, particularly gyneco-mastia, female distribution of hair and testicular atrophy and 5. Changes in the color of the skin like icterus and melanosis cutis. Rarely pruritus and other diseases of the skin are seen, such as porphyria cutanea tarda, which is often caused by an altered liver function. In the final stages of alcoholism, the neglect of personal hygiene particularly of the skin is evident (cutis vagantium). Since the exact mechanism of the skin symptoms remains obscure, it is difficult to evaluate the significance. Most often they do not correlate with the severity of the liver disease.

The liver diseases of pregnancy are specific liver disorders during the pregnancy. The principal hepatic anomaly during hyperemesis gravidarum is a reversible augmentation of liver enzymes under reanimation. Intrahepatic cholestasis of pregnancy occur during the last 2 trimesters of pregnancy, manifested usually by pruritus preceeding a jaundice. The liver enzymes and the serum biliary acids are augmented. The acute fatty liver of pregnancy occur during the last trimester of pregnancy leading to early interruption of pregnancy which would help to diminish the elevated level of maternal and fetal mortality. The HELLP syndrome usually observed during the toxemia of pregnancy, associate an hemolysis elevation of liver enzymes and low platelets.

Intrahepatic cholestasis of pregnancy is a hepatopathy that occurs in the second or third trimester and accounts for 20% of cases of jaundice occurring in pregnancy. Both genetic and hormonal factors appear to play important roles in its development. The leading symptom is pruritus, and jaundice is common. Transaminases, serum bile acids and bilirubin are typically elevated, while gamma-GT is usually normal. For the differential diagnosis, in particular viral hepatitis, cholelithiasis, gestosis and acute fatty liver of pregnancy must be excluded. While the prognosis of intrahepatic cholestasis of pregnancy for the mother is good, the associated increased tendency for a premature birth represents a potential risk for the child. Early treatment with ursodeoxycholic acid appears to have a positive influence on both the mother's symptoms and the course of the pregnancy. Should the symptoms persist after delivery, consideration must be given to a chronic hepatopathy.
