Abnormal liver function tests occur in 3 - 5% of pregnancies for different reasons. Apart from pre-existing liver diseases liver diseases occurring during pregnancy, such as gall stones or viral hepatitis, most liver dysfunctions in pregnancy are caused by one of the five pregnancy-related liver diseases. The five known pregnancy-related liver diseases can be classified in two main categories depending on their association with or without preeclampsia. The preeclampsia-associated liver diseases are the preeclampsia itself, the HELLP-syndrome ("Hemolysis" (H), "Elevated Liver Tests" (EL), "Low Platelet Count" (LP)) and the acute fatty liver of pregnancy. Hyperemesis gravidarum and intrahepatic cholestasis of pregnancy are not associated with preeclampsia. Hyperemesis gravidarum is characterised by intractable vomiting in the first trimester of pregnancy. 50% of patients with this condition have liver dysfunction. Intrahepatic cholestasis of pregnancy presents with pruritus and elevated bile acids in the second half of pregnancy. Patients have often mild jaundice and highly elevated liver enzymes. Treatment of choice is ursodeoxycholic acid to relieve the mother's symptoms. With this condition mainly the fetus is at risk. Severe preeclampsia is the most common cause of liver dysfunction in pregnancy, and is in some cases further complicated by HELLP syndrome. The prompt delivery of the baby is the only definitive therapy. However, many life-threatening maternal complications like liver hematoma or rupture and abruptio placentae can occur. Acute fatty liver of pregnancy is also a severe illness occuring mostly in the third trimester; microvesicular fat deposition in the liver can cause liver failure with coagulopathy and encephalopathy. Only the immediate delivery of the fetus can save mother and child.

NICCD is an autosomal recessive genetic disorder, characterized by cholestasis, coagulopathy, hypoglycemia, fatty liver and multiple amino acidemia. NICCD develops in the neonatal/infantile period and has been reported as a "naturally curable" disease within one yr of life. Recently, we experienced an infantile NICCD who developed progressive liver failure, and required subsequent LT using a heterozygote living donor at eight months of age. Diagnosis of NICCD was established before transplantation, and donor evaluation included mutation in the SLC25A13 gene for exclusion of individuals with citrin deficiency citrullinemia. LDLT, from blood type identical mother using a left lateral segment graft, was performed without serious complication. Plasma amino acid concentration was normalized rapidly, and the patient was discharged 30 days after transplant. During one yr follow up, the recipient has been doing well without additional medication for NICCD. NICCD should be considered in the differential diagnosis as a cause of neonatal/infantile cholestatic disease. LT using a heterozygote living donor is an effective alternative in countries where a deceased donor is not available.

A 24-year-old female at 34-week gestation, presented with malaise, nausea, vomiting, jaundice, and absent foetal movements. A clinical diagnosis of acute fatty liver of pregnancy was made. Although early caesarean section was performed, postoperative course was complicated by acute respiratory distress syndrome (ARDS) sepsis, and continuing coagulopathy. Supportive management in an intensive care unit resulted in successful outcome.

A 17-year-old-female at 39 weeks gestation, presented with pelvic pain, proteinuria and a decrease in fetal heart rate. Timely caesarean section was performed. The postoperative course was complicated by acute renal failure, acute pancreatitis, acute liver failure, anemia, thrombocytopenia, systemic inflammatory response syndrome (SIRS), prolonged coagulopathy, hyperbilirubinemia, ecclampsia, and psychosis. The clinical features and laboratory abnormalities, in conjunction with the timing of gestational age, led to the diagnosis of acute fatty liver of pregnancy. Prompt diagnosis and supportive care in an intensive care unit provided for a positive outcome.

Control of postpartum hemorrhage is difficult in patients with coagulopathy due to acute liver failure. Recombinant activated factor VII (rFVIIa) can help in control of bleed; however, it has short duration of action (2-4 h). The study aimed to report the use of rFVIIa in this setting. We retrospectively analyzed all patients with acute liver failure secondary to pregnancy-related liver disorders who received rFVIIa for control of postpartum hemorrhage (six patients, all six met diagnostic criteria for acute fatty liver of pregnancy). One dose of rFVIIa achieved adequate control of bleeding in five patients, while one patient needed a second dose. rFVIIa administration corrected coagulopathy and significantly reduced requirement of packed red cells and other blood products. No patient had thrombotic complications. In conclusion, rFVIIa was a useful adjunct to standard management in postpartum hemorrhage secondary to acute liver failure of pregnancy-related liver disorders.

A young woman presented with a febrile illness in the third trimester of pregnancy. Laboratory investigation revealed severe acute hepatitis with thrombocytopenia and coagulopathy. Liver injury progressed despite emergent caesarian section and delivery of a healthy infant. Therefore, therapeutic plasma exchange (TPE) was performed on three consecutive days post-partum for a presumed diagnosis of acute liver failure (ALF) associated with pregnancy due to hemolysis, elevated liver enzymes, and low platelets (HELLP) or acute fatty liver of pregnancy (AFLP). Treatment with TPE was followed by biochemical and clinical improvement but during her recovery herpes simplex virus type 2 (HSV-2) infection was diagnosed serologically and confirmed histologically. Changes in the immune system during pregnancy make pregnant patients more susceptible to acute HSV hepatitis, HSV-related ALF, and death. The disease is characterized by massive hepatic inflammation with hepatocyte necrosis, mediated by both direct viral cytotoxicity and the innate humoral immune response. TPE may have a therapeutic role in acute inflammatory disorders such as HSV hepatitis by reducing viral load and attenuating systemic inflammation and liver cell injury. Further investigation is needed to clarify this potential effect. The roles of vigilance, clinical suspicion, and currently accepted therapies are emphasized.

Abetalipoproteinemia (ABL; OMIM 200100) and homozygous hypobetalipoproteinemia (HHBL; OMIM 107730) are rare diseases characterized by hypocholesterolemia and malabsorption of lipid-soluble vitamins leading to retinal degeneration, neuropathy and coagulopathy. Hepatic steatosis is also common. The root cause of both disorders is improper packaging and secretion of apolipoprotein (apo) B-containing lipoprotein particles due to mutations either in both alleles of the MTP (alias MTTP) gene encoding microsomal triglyceride transfer protein (MTP) or both alleles of the APOB gene itself in the case of ABL and HHBL, respectively. Clinical diagnosis is based on signs and symptoms, acanthocytosis on blood smear, and virtually absent apo B-containing lipoproteins, including chylomicrons, very low density lipoprotein and low density lipoprotein. Obligate heterozygote parents of ABL patients usually have normal lipids consistent with autosomal recessive inheritance, while heterozygous parents of HHBL patients typically have half normal levels of apo B-containing lipoproteins consistent with autosomal co-dominant inheritance. Definitive diagnosis involves sequencing the MTP and APOB genes, for which >30 and >60 mutations have been described for ABL and HHBL, respectively. Follow-up includes monitoring for ophthalmologic, neurologic, hematologic, and hepatic complications, as well as compliance with treatment. Investigations include lipid profile, serum transaminases, markers for lipid-soluble vitamins, and periodic instrumental assessment of ocular and neurological function. Mainstays of treatment include adherence to a low-fat diet, and supplementation with essential fatty acids and high oral doses of fat soluble vitamins. Prognosis is variable, but early diagnosis and strict adherence to treatment can recover normal neurological function and halt disease progression.

A 20-year-old woman, primigravida at 36(+4) weeks' gestation presented with malaise, vomiting for 1 week, yellowish discoloration of the eyes for 3 days and loss of fetal movements. A clinical diagnosis of acute fatty liver with intrauterine fetal demise was made. Labor was induced with prostaglandin E2 gel and delivered vaginally. The post-partum period was complicated by atonic post-partum hemorrhage, an episode of seizure, recurrent hypoglycemic attack, hypokalemia and continuing coagulopathy. Supportive management in the intensive care unit using blood and blood products and injection recombinant activated factor VIIa to arrest the bleeding resulted in a successful outcome.

Disseminated intravascular coagulation (DIC) is a syndrome that can be initiated by a myriad of medical, surgical, and obstetric disorders. Also known as consumptive coagulopathy, DIC is a common contributor to maternal morbidity and mortality and is associated with up to 25% of maternal deaths. The etiopathogenesis of DIC is complex and currently thought to be initiated by tissue factor or thromboplastin, which is released from trophoblastic or fetal tissue, or maternal decidua or endothelium. Tissue factor activates the coagulation sequence to cause fibrin clotting and its dissolution by the fibrinolysin system. The result of this process can range from mild, clinically insignificant laboratory derangements to marked coagulopathy with bleeding at sites of minimal trauma. Although clinical recognition varies by disease severity, several organizations have attempted to standardize the diagnosis through development of scoring systems. Several important--albeit not necessarily common--obstetric disorders associated with DIC include placental abruption, amniotic fluid embolism, sepsis syndrome, and acute fatty liver of pregnancy. More common disorders include severe preeclampsia, hemolysis, elevated liver enzymes, and low platelet count syndrome, and massive obstetric hemorrhage. Importantly, many of these disorders either cause or are associated with substantive obstetric hemorrhage. Treatment of DIC is centered on two principles. The first is identification and treatment of the underlying disorder. Because many women with consumptive coagulopathy also have massive hemorrhage, the second tenet of treatment is that obstetric complications such as uterine atony or lacerations must be controlled simultaneously with prompt blood and component replacement for a salutary outcome.

Infantile liver failure syndrome type 1 (ILFS1) is a Mendelian disease due to biallelic mutations in the cytoplasmic leucyl-tRNA synthetase gene (LARS). This study aimed to report the clinical and molecular features of the first non-caucasian ILFS1 patient, providing reliable evidences for the definite diagnosis of ILFS1. The 2 years and 9 months old male patient was referred to the hospital with hepatosplenomegaly over 1 year. At age 17 months, he was found to have hepatosplenomegaly and anemia. Since then, he had been managed in different hospitals. The laboratory tests showed liver dysfunction, hypoproteinemia, coagulopathy and anemia, along with histologically-confirmed cirrhosis and fatty liver; however, the etiology remained undetermined. The subsequent SLC25A13 mutation analysis by means of prevalent mutation screening and Sanger sequencing only revealed a paternally-inherited mutation c.1658G>A, and no aberrant SLC25A13 transcripts could be detected from the maternal allele on cDNA cloning analysis, ruling out the possibility of citrin deficiency. Further target exome high-throughout sequencing of genes relevant to genetic liver diseases detected a paternal c.2133_2135del (p.L712del) and a maternal c.1183G>A (p.D395N) mutation in LARS gene. This finding was then confirmed by Sanger sequencing, and ILFS1 was thus definitely diagnosed. The child has been followed up till age 4 years, and his condition became stabilized.
