ANIT-induced disruption of biliary function in rat hepatocyte couplets. (1/294)

alpha-Naphthylisothiocyanate (ANIT) induces intrahepatic cholestasis in rats, involving damage to biliary epithelial cells; our study aims to investigate whether disruption of biliary function in hepatocytes can contribute to early stages of ANIT-induced intrahepatic cholestasis. Isolated rat hepatocyte couplets were used to investigate biliary function in vitro by canalicular vacuolar accumulation (cVA) of a fluorescent bile acid analogue, cholyl-lysyl-fluorescein (CLF), within the canalicular vacuole between the two cells. After a 2-h exposure to ANIT, there was a concentration-dependent inhibition of cVA (cVA-IC50; 25 microM), but no cytotoxicity (LDH leakage or [ATP] decline) within this ANIT concentration range. There was no loss of cellular [GSH] at low ANIT concentrations, but, at 50 microM ANIT, a small but significant loss of [GSH] had occurred. Diethylmaleate (DEM) partially depleted cellular [GSH], but addition of 10 microM ANIT had no further effect on GSH depletion. Reduction in cVA was seen in DEM-treated cells; addition of ANIT to these cells reduced cVA further, but the magnitude of this further reduction was no greater than that caused by ANIT alone, indicating that glutathione depletion does not enhance the effect of ANIT. F-actin distribution (by phalloidin-FITC staining) showed an increased frequency of morphological change in the canalicular vacuoles but only a small, non-significant (0.05 < p < 0.1) increase in proportion of the F-actin in the region of the pericanalicular web. The results are in accord with a disruption of hepatocyte canalicular secretion within two h in vitro, at low, non-cytotoxic concentrations of ANIT, and the possible involvement of a thiocabamoyl-GSH conjugate of ANIT (GS-ANIT) in this effect.  (+info)

Bile acid patterns in meconium are influenced by cholestasis of pregnancy and not altered by ursodeoxycholic acid treatment. (2/294)

BACKGROUND: Data on meconium bile acid composition in newborn babies of patients with intrahepatic cholestasis of pregnancy (ICP) are relatively scant, and changes that occur on ursodeoxycholic acid (UDCA) administration have not been evaluated. AIMS: To investigate bile acid profiles in meconium of neonates from untreated and UDCA treated patients with ICP. Maternal serum bile acid composition was also analysed both at diagnosis and delivery to determine whether this influences the concentration and proportion of bile acids in the meconium. PATIENTS/METHODS: The population included eight healthy pregnant women and 16 patients with ICP, nine of which received UDCA (12.5-15.0 mg/kg body weight/day) for 15+/-4 days until parturition. Bile acids were assessed in the meconium by gas chromatography-mass spectrometry and in maternal serum by high performance liquid chromatography. RESULTS: Total bile acid and cholic acid concentrations in the meconium were increased (p<0.01) in newborns from patients with ICP (13.5 (5.1) and 8.4 (4.1) micromol/g respectively; mean (SEM)) as compared with controls (2.0 (0.5) and 0.8 (0.3) micromol/g respectively), reflecting the total bile acid and cholic acid levels in the maternal serum (r = 0.85 and r = 0.84, p<0.01). After UDCA administration, total bile acid concentrations decreased in the mother ( approximately 3-fold, p<0. 05) but not in the meconium. UDCA concentration in the meconium showed only a 2-fold increase after treatment, despite the much greater increase in the maternal serum (p<0.01). Lithocholic acid concentration in the meconium was not increased by UDCA treatment. CONCLUSIONS: UDCA administration does not influence the concentration and proportion of bile acids in the meconium, which in turn are altered by ICP. Moreover, this beneficial treatment for the mother does not increase meconium levels of potentially toxic metabolites of UDCA such as lithocholic acid.  (+info)

Sensorineural hearing loss associated with Byler disease. (3/294)

Progressive familial intrahepatic cholestasis, sometimes described as Byler disease, is a lethal liver disease and its inheritance is autosomal recessive. There is a previous report on the occasional association between this disease and sensorineural hearing loss without any audiological findings. We report here two siblings, an 18-year-old female and a 16-year-old male, suffering from Byler disease and hearing loss. Pure tone, Bekesy and speech audiometries and auditory brain stem response examination were performed. Audiometric data showed hearing characteristics of cochlear origin, high-frequency loss and progressiveness. This sensorineural hearing loss possibly results from a genetic mutation. The mechanism of cochlear disorder in patients with Byler disease is unknown, however, a novel gene responsible for deafness might be found to be related to Byler disease.  (+info)

Review article: mechanisms of action and therapeutic applications of ursodeoxycholic acid in chronic liver diseases. (4/294)

Ursodeoxycholic acid (ursodiol) is a non-toxic, hydrophilic bile acid used to treat predominantly cholestatic liver disorders. Better understanding of the cellular and molecular mechanisms of action of ursodeoxycholic acid has helped to elucidate its cytoprotective, anti-apoptotic, immunomodulatory and choleretic effects. Ursodeoxycholic acid prolongs survival in primary biliary cirrhosis and it improves biochemical parameters of cholestasis in various other cholestatic disorders including primary sclerosing cholangitis, intrahepatic cholestasis of pregnancy, cystic fibrosis and total parenteral nutrition-induced cholestasis. However, a positive effect on survival remains to be established in these diseases. Ursodeoxycholic acid is of unproven efficacy in non-cholestatic disorders such as acute rejection after liver transplantation, non-alcoholic steatohepatitis, alcoholic liver disease and chronic viral hepatitis. This review outlines the present knowledge of the modes of action of ursodeoxycholic acid, and presents data from clinical trials on its use in chronic liver diseases.  (+info)

Manganese-bilirubin effect on cholesterol accumulation in rat bile canalicular membranes. (5/294)

Manganese-bilirubin (Mn-BR)-induced cholestasis in rats is associated with altered lipid composition of various hepatic subcellular fractions. Increased bile canalicular (BCM) cholesterol content in Mn-BR cholestasis and the intracellular source of the accumulating cholesterol were investigated. To label the total hepatic cholesterol pool, male Sprague-Dawley rats were given ip 3H-cholesterol, followed 18 h later by 2-14C-mevalonic acid (a precursor of cholesterol synthesis). To induce cholestasis, manganese (Mn, 4.5 mg/kg) and bilirubin (BR, 25 mg/kg) were injected iv; animals were killed 30 min after BR injection; canalicular and sinusoidal membranes, microsomes, mitochondria, and cytosol were isolated. Total cholesterol content of each fraction was determined by spectrophotometric techniques as well as radiolabeled techniques. In Mn-BR cholestasis, the total cholesterol concentrations of BCM and cytosol were significantly increased. Also, the contribution of 14C-labeled cholesterol (newly synthesized cholesterol) was enhanced in all isolated cellular fractions. The results are consistent with the hypothesis that accumulation of newly synthesized cholesterol in BCM is involved in Mn-BR cholestasis. An enhanced rate of synthesis of cholesterol, however, does not appear to be the causal event, as the activity of HMG-CoA reductase (rate-limiting enzyme in cholesterol synthesis), assessed in vitro, was decreased following Mn-BR treatment. Treatment with the Mn-BR combination may affect other aspects of intracellular cholesterol dynamics.  (+info)

Fibrosing cholestatic hepatitis: a report of three cases. (6/294)

Fibrosing cholestatic hepatitis is an aggressive and usually fatal form of viral hepatitis in immunosuppressed patients. We report three cases of fibrosing cholestatic hepatitis in various clinical situations. Case 1 was a 50-year-old man who underwent a liver transplant for hepatitis B virus (HBV)-associated liver cirrhosis. Two and a half years after the transplant, he complained of fever and jaundice, and liver enzymes were slightly elevated. Serum HBsAg was positive. Case 2 was a 30-year-old man in an immunosuppressed state after chemotherapy for acute lymphoblastic leukemia. He was a HBV carrier. Liver enzymes and total bilirubin were markedly elevated. Case 3 was a 50-year-old man who underwent renal transplantation as a known HBV carrier. One year after the transplant, jaundice developed abruptly, but liver enzymes were not significantly elevated. Microscopically lobules were markedly disarrayed, showing ballooning degeneration of hepatocytes, prominent pericellular fibrosis, and marked canalicular or intracytoplasmic cholestasis. Portal inflammation was mild, but interphase activity was definite and cholangiolar proliferation was prominent. Hepatocytes were diffusely positive for HBsAg and HBcAg in various patterns. Patients died of liver failure within 1 to 3 months after liver biopsy in spite of anti-viral treatment.  (+info)

Plasma antioxidant levels in chronic cholestatic liver diseases. (7/294)

BACKGROUND: [corrected] A predictable consequence of cholestasis is malabsorption of fat-soluble factors, (vitamins A, D, E, K) and other free radical scavengers, such as carotenoids. It has been suggested that oxygen-derived free radicals may be involved in the pathogenesis of chronic liver damage. AIMS: (i) To evaluate retinol, alpha-tocopherol and carotenoid plasma levels in two groups of patients with chronic cholestatic liver disease (primary biliary cirrhosis and primary sclerosing cholangitis); (ii) to compare the respective plasma levels with those of the general population; (iii) to correlate the plasma levels with disease severity. METHODS: A total of 105 patients with chronic cholestasis were included in the study: 86 with primary biliary cirrhosis (81 female, five male, mean age 55.5 +/- 11 years), 19 with primary sclerosing cholangitis (seven female, 12 male, mean age 35 +/- 11 years; six patients had associated inflammatory bowel disease); 105 sex- and age-matched subjects from the general population in the same geographical area (88 female, 17 male, mean age 51.3.5 +/- 10 years) served as controls. Carotenoids (lutein zeaxanthin, lycopene, beta-carotene, alpha-carotene, beta-cryptoxanthin), retinol and alpha-tocopherol were assayed by high-pressure liquid chromatography. A food frequency questionnaire was administered to each subject to evaluate the quality and the quantity of dietary compounds. Data were processed by analysis of variance and linear regression analysis, as appropriate. RESULTS: Both primary biliary cirrhosis and primary sclerosing cholangitis patients had significantly lower levels of retinol, alpha-tocopherol, total carotenoids, lutein, zeaxanthin, lycopene, alpha- and beta-carotene than controls (P < 0.0001). Among the cholestatic patients, no significant difference in the concentration of antioxidants was observed between primary biliary cirrhosis and primary sclerosing cholangitis subjects. Anti-oxidant plasma levels were not affected by the severity of the histological stage in primary biliary cirrhosis, but a negative correlation was found between total carotenoids and both alkaline phosphatase (ALP) and gammaglutamyl transpeptidase (GGT) (P < 0.013 and P < 0.018, respectively). Within the primary sclerosing cholangitis group, no correlation was found between total carotenoids and cholestatic enzymes. Nutritional intake in cholestatic patients was comparable to controls, including fruit and vegetable intake. CONCLUSIONS: Although no clinical sign of deficiency is evident, plasma levels of antioxidants are low in cholestatic patients even in early stages of the disease. This is probably due to malabsorption of fat-soluble vitamins, as well as other mechanisms of hepatic release, suggesting the need for dietary supplementation.  (+info)

Heterozygous MDR3 missense mutation associated with intrahepatic cholestasis of pregnancy: evidence for a defect in protein trafficking. (8/294)

Intrahepatic cholestasis of pregnancy (ICP) is a liver disease of pregnancy with serious consequences for the mother and fetus. Two pedigrees have been reported with ICP in the mothers of children with a subtype of autosomal recessive progressive familial intrahepatic cholestasis (PFIC) with raised serum gamma-glutamyl transpeptidase (gamma-GT). Affected children have homozygous mutations in the MDR3 gene (also called ABCB4 ), and heterozygous mothers have ICP. More frequently, however, ICP occurs in women with no known family history of PFIC and the genetic basis of this disorder is unknown. We investigated eight women with ICP and raised serum gamma-GT, but with no known family history of PFIC. DNA sequence analysis revealed a C to A transversion in codon 546 in exon 14 of MDR3 in one patient, which results in the missense substitution of the wild-type alanine with an aspartic acid. We performed functional studies of this mutation introduced into MDR1, a closely related homologue of MDR3. Fluorescence activated cell sorting (FACS) and western analysis indicated that this missense mutation causes disruption of protein trafficking with a subsequent lack of functional protein at the cell surface. The demonstration of a heterozygous missense mutation in the MDR3 gene in a patient with ICP with no known family history of PFIC, analysed by functional studies, is a novel finding. This shows that MDR3 mutations are responsible for the additional phenotype of ICP in a subgroup of women with raised gamma-GT.  (+info)

Progressive Familial Intrahepatic Cholestasis Type 2 (PFIC2) is a rare congenital cholestatic liver disease that progresses to end stage liver disease. It is associated with fat soluble vitamin D deficiency rickets and severe dyslipidemia; however, treatment of these secondary effects remains a challenge. One year old twin males born to a mother with intrahepatic cholestasis during pregnancy presented with jaundice, pruritus and failure to thrive. Lab evaluation revealed significant transaminitis, direct hyperbilirubinemia and normal gamma glutamyl transferase (GGT). Genetic studies confirmed PFIC2. Further evaluation for fat soluble vitamin deficiencies revealed severe vitamin D deficiency rickets. High dose vitamin D replacement therapy using Ergocalciferol (Vitamin D2) 50,000 IU three times a week over 10 weeks led to the improvement of Vitamin D, 25-Hydroxy (25-OH) serum levels and resolution of rickets. Dyslipidemia with very low high density lipoprotein-cholesterol (HDL-C) and high triglycerides

Progressive familial intrahepatic cholestasis (PFIC) comprises a group of rare cholestatic liver disorders of childhood that could lead to liver cirrhosis. Nowadays, the partial biliary diversion procedure is still a therapeutic option in non-cirrhotic children with PFIC1 or PFIC2 after an ineffective ursodeoxycholic acid (UDCA) therapy. However, the relevant disadvantage of the partial external biliary diversion (PEBD) is that adolescent patients could not accept a permanent stoma. In some of them, despite of good clinical and biochemical results of this procedure, the ileal exclusion (IE) procedure had to be performed many years after PEBD. Our aims were to find the most characteristic early microscopic features of the disease as well as to compare changes in the liver biopsy specimens at the time of diagnosis and long-time (more than 10 years) after a surgical procedure. We examined retrospectively 8 liver biopsies from 4 PFIC2 patients comparing the results from the first biopsies done at ...
Progressive familial intrahepatic cholestasis (PFIC) is a rare genetic liver disease that affects infants and children. In many cases, patients diagnosed with PFIC experience end-stage liver disease by 10 years old.1 A serious consequence of PFIC is severe itching that can lead to sleepless nights for the whole family. If left unprotected, babies may even scratch through their skin causing bleeding, scabs, and wounds.

Progressive familial intrahepatic cholestasis 2 is a rare condition and is one of many forms of cholestasis. Cholestasis is a rare disease where a persons liver can not move the bile it makes to the small intestine. The liver, an organ, is responsible for producing bile. Bile is a compound that helps people digest fats. Once the bile has been made, it is supposed to go to the small intestine, another organ, to digest the fats there. However, in people with cholestasis, the bile can not move to the small intestine because there is either a physical block or because the bile is stuck in the liver cells. Symptoms of cholestasis are itchiness, jaundice (yellowing of the skin), pale stool, and dark urine. People with progressive familial intraheptic cholestasis 2 are not able to move the bile from the cells in the liver that produce it to the small intestine to digest fats. Talk with your doctor to find the best treatment for you if you have been diagnosed with progressive familial intraheptic ...
Mutations in the ATP8B1 gene cause two autosomal recessive disorders affecting liver: cholestasis, benign recurrent intrahepatic, 1 (BRIC1), cholestasis, progressive familial intrahepatic, 1 (PFIC1) and one autosomal dominant disorder: cholestasis, intrahepatic, of pregnancy, 1 (ICP1). BRIC2 is caused by mutations in the ABCB11 gene. PFIC can be caused by mutations in three other genes: ABCB11 (PFIC2), ABCB4 (PFIC3) and TJP2 (PFIC4). Mutations in the ABCB4 gene have been reported in ICP3. BRIC is characterized by intermittent episodes of cholestasis without extrahepatic bile duct obstruction. PFIC is characterized by early onset of cholestasis that progresses to hepatic fibrosis, cirrhosis, and end-stage liver disease before adulthood. ICP typically occurs in the third trimester and it recurs in 45 to 70% of subsequent pregnancies. Findings include pruritus, jaundice, increased serum bile salts, and abnormal liver enzymes. This condition is reversible, but it can result in fetal complications ...
Mutations in the ATP8B1 gene can cause benign recurrent intrahepatic cholestasis 1 (BRIC1) or progressive familial intrahepatic cholestasis 1 (PFIC1), commonly known as ATP8B1 deficiency. ATP8B1 is an aminophospholipid flippase, maintaining membrane asymmetry. In ATP8B1 deficiency the activity of the bile salt export pump (BSEP) which pumps bile salts out ... read more of the hepatocytes into the bile duct is decreased, leading to accumulation of bile salts and cell damage. However, the mechanism by which ATP8B1 defects causes cholestasis is unknown. Involvement of the nuclear receptor FXR or reduced membrane stability and consequent decreased BSEP activity have been suggested. Proper ATP8B1 folding and association with CDC50A is required for ATP8B1 to exit the ER and traffic to the plasma membrane. It was recently demonstrated that ATP8B1 mutations often result in protein misfolding and subsequent ER retention and protein degradation. Molecular chaperones facilitate protein folding and ...

ATP-binding cassette, sub-family B member 11 also known as ABCB11 is a protein which in humans is encoded by the ABCB11 gene. The product of the ABCB11 gene is an ABC transporter named BSEP (Bile Salt Export Pump), or sPgp (sister of P-glycoprotein). This membrane-associated protein is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Some members of the MDR/TAP subfamily are involved in multidrug resistance. This particular protein is responsible for the transport of taurocholate and other cholate conjugates from hepatocytes (liver cells) to the bile. In humans, the activity of this transporter is the major determinant of bile formation and bile flow. ABCB11 is a gene associated with progressive familial intrahepatic cholestasis type 2 ...

Intrahepatic Cholestasis of Pregnancy (ICP), also termed Obstetric Cholestasis in the United Kingdom, is a reversible form of cholestasis, a liver disorder that occurs in pregnant women. ICP gives rise to troublesome itching during pregnancy but may lead to possibly serious complications for the mother and very serious outcomes for the fetus. Itching has long been considered to be a common symptom of pregnancy. The vast majority of times, itching, or pruritus is a minor annoyance caused by changes to the skin, especially that of the abdomen.. Cholestasis is a condition that impairs the release of a digestive fluid called bile from liver cells. As a result, bile builds up in the liver, impairing liver function. Because the problems with bile release occur within the liver (intrahepatic), the condition is described as intrahepatic cholestasis. Intrahepatic cholestasis of pregnancy usually becomes apparent in the third trimester of pregnancy and recurs in 45 to 70% of subsequent pregnancies. Bile ...

BACKGROUND: Though possession of androgenic anabolic steroids (AAS) is illegal, non-prescription use of AAS persists. METHODS: We describe two Caucasian males (aged 25 and 45 years) with cholestatic hepatitis following ingestion of the dietary supplement Mass-Drol (Celtic Dragon) containing the AAS 2α-17α-dimethyl-etiocholan-3-one,17β-ol.. RESULTS: Despite substantial hyperbilirubinaemia peak gamma-glutamyl transferase (GGT) remained normal. Besides bland intralobular cholestasis, liver biopsy in both found deficiency of canalicular expression of ectoenzymes as seen in ATP8B1 disease. In the older patient, bile salt export pump marking (encoded by ABCB11) was focally diminished. We hypothesized that AAS had either induced inhibition of normal ATP8B1/ABCB11 expression or triggered initial episodes of benign recurrent intrahepatic cholestasis (BRIC) type 1/or 2. On sequencing, ATP8B1 was normal in both patients although the younger was heterozygous for the c.2093G,A mutation in ABCB11, a ...

BACKGROUND: Partial internal biliary diversion (PIBD) is an alternative approach for the treatment of devastating pruritus in patients with progressive familial intrahepatic cholestasis (PFIC). In these patients quality of life can be improved and progression of liver disease can be delayed while waiting for liver transplantation. The aim of our study was to evaluate six patients with PFIC who have undergone PIBD in long-term follow-up. METHODS: Retrospective review of the records of six patients who underwent PIBD for PFIC between 2008 and 2010 was conducted to evaluate age, growth, clinical and laboratory studies for long-term outcome ...
β-Catenin, the downstream effector of the Wnt signaling, plays important roles in hepatic development, regeneration and tumorigenesis. However, its role at hepatocyte adherens junctions (AJ) is relatively poorly understood, chiefly due to spontaneous compensation by γ-catenin. Here, we simultaneously ablate β- and γ-catenin expression in mouse liver by interbreeding β-catenin-γ-catenin double-floxed mice and albumin-cre transgenic mice. Double knockout mice (DKO) show failure to thrive, impaired hepatocyte differentiation, cholemia, ductular reaction, progressive cholestasis, inflammation, fibrosis and tumorigenesis, which was associated with deregulation of tight junctions (TJ) and bile acid transporters, leading to early morbidity and mortality, a phenotype reminiscent of Progressive Familial Intrahepatic Cholestasis (PFIC ...
The European Medicines Agency Committee for Orphan Medicinal Products (COMP) has issued a positive opinion for orphan medicinal product status for the Albireo ABs lead hepatology candidate, A4250, for the treatment of primary billary cirrhosis (PBC), progressive familial intrahepatic cholestasis (PFIC) and alagille syndrome.. The positive opinion of the COMP has now been forwarded to the EU commission for final approval. PBC is a slowly progressive autoimmune disease of the liver, primarily affecting women. The average age when symptoms start is around 40-50 years of age. PBC is characterised by destruction of bile ducts resulting in an increased bile acid concentration in the liver inducing inflammation and cirrhosis. There are more than 100.000 patients with PBC in Europe. Main symptoms are fatigue, severe itching and symptoms of cirrhosis. There is no cure for PBC. Some therapeutic alternatives may slow disease progression and relieve symptoms but some patients may need liver ...

Mutations in the ATP8B1 gene cause two autosomal recessive disorders affecting liver: cholestasis, benign recurrent intrahepatic, 1 (BRIC1), cholestasis, progressive familial intrahepatic, 1 (PFIC1) and one autosomal dominant disorder: cholestasis, intrahepatic, of pregnancy, 1 (ICP1). BRIC2 is caused by mutations in the ABCB11 gene. PFIC can be caused by mutations in three other genes: ABCB11 (PFIC2), ABCB4 (PFIC3) and TJP2 (PFIC4). Mutations in the ABCB4 gene have been reported in ICP3. BRIC is characterized by intermittent episodes of cholestasis without extrahepatic bile duct obstruction. PFIC is characterized by early onset of cholestasis that progresses to hepatic fibrosis, cirrhosis, and end-stage liver disease before adulthood. ICP typically occurs in the third trimester and it recurs in 45 to 70% of subsequent pregnancies. Findings include pruritus, jaundice, increased serum bile salts, and abnormal liver enzymes. This condition is reversible, but it can result in fetal complications ...
UNLABELLED: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disease, characterized by maternal pruritus and raised serum bile acids. Our objectives were to describe the epidemiology and pregnancy complications associated with severe ICP and to test the hypothesis that adverse perinatal outcomes are increased in these women. A prospective population-based case-control study with national coverage was undertaken using the UK Obstetric Surveillance System (UKOSS). Control data for comparison were obtained from women with healthy pregnancy outcome through UKOSS (n = 2,232), St Marys Maternity Information System (n = 554,319), and Office for National Statistics (n = 668,195). The main outcome measures investigated were preterm delivery, stillbirth, and neonatal unit admission. In all, 713 confirmed cases of severe ICP were identified, giving an estimated incidence of 9.2 per 10,000 maternities. Women with severe ICP and a singleton pregnancy (n = 669) had increased risks of preterm

A 33-year-old Japanese man who had suffered from liver cirrhosis due to hepatitis C virus (HCV) underwent living related liver transplantation (LRLT). The allograft was given by his brother, who was healthy with no history of hepatitis or hepatic virus infection. After LRLT, the patients hepatitis C recurred. Liver biopsy revealed chronic viral hepatitis and no allograft rejection such as shown by portal lymphocytic infiltration or mild bridging fibrosis. Interferon and ribavirin were administered, and sustained viral response (SVR) was obtained. Although serum hepatitis B virus (HBV)-DNA/HCV-RNA polymerase chain reaction found no presence of hepatic virus, the serum examination demonstrated liver dysfunction seven months after SVR. Liver biopsies histopathologically showed portal fibrosis invading to the sinusoids, cholestasis, mild hyperplasia of the cholangioles, and no features of allograft rejection. Fibrosing cholestatic hepatitis (FCH) was diagnosed. The FCH was resistant to treatment ...
Background: Intrahepatic cholestasis of pregnancy (ICP) is characterised by troublesome maternal pruritus, raised serum bile acid levels and increased fetal risk. Mutations of the ABCB4 gene encoding the hepatobiliary phospholipid transporter have been identified in a small proportion of patients with cholestasis of pregnancy. In a recent prospective study on 693 patients with cholestasis of pregnancy, a cut-off level for serum bile acid (⩾40 μmol/l) was determined for increased risk of fetal complications.. Objectives: To investigate whether common combinations of polymorphic alleles (haplotypes) of the genes encoding the hepatobiliary ATP-binding cassette (ABC) transporters for phospholipids (ABCB4) and bile acids (ABCB11) were associated with this severe form of cholestasis of pregnancy.. Methods: For genetic analysis, 52 women with bile acid levels ⩾40 μmol/l (called cases) and 52 unaffected women (called controls) matched for age, parity and geographical residence were studied. Gene ...
A 57-yr-old man presented with clinical and laboratory signs of acute cholestatic hepatitis. Symptoms had appeared 7 wk after he was started on pravastatin 20 mg/day for hypercholesterolemia. A full evaluation including ultrasound, computed tomography, endoscopic cholangiography, and liver biopsy confirmed the diagnosis of intrahepatic nonobstructive jaundice. The liver function abnormalities normalized 7 wk after cessation of therapy. Pravastatin should be considered as a potential cause of cholestatic hepatitis with favorable clinical outcome after drug withdrawal ...
Intrahepatic cholestasis of pregnancy (ICP), also known as obstetric cholestasis, cholestasis of pregnancy, jaundice of pregnancy, and prurigo gravidarum, is a medical condition in which cholestasis occurs during pregnancy. It typically presents with troublesome itching and can lead to complications for both mother and fetus. Pruritus (itching) has long been considered to be a common symptom of pregnancy. The vast majority of times, itching is a minor annoyance caused by changes to the skin, especially that of the abdomen. However, there are instances when itching is a symptom of ICP. This is usually most intense on the palms of the hands, and the soles of the feet, but can be widespread. ICP occurs most commonly in the third trimester, but can begin at any time during the pregnancy. Most women with this condition present in third trimester with itching without a rash. Typically, the itching is localized to the palms of the hands and soles of the feet but can be anywhere on the body. Hallmarks ...
ICP (intrahepatic cholestasis of pregnancy) is characterized by pruritus and biochemical cholestasis, including raised SBAs (serum bile acids) and, usually, elevated aminotransferases levels. However, AHP (asymptomatic hypercholanaemia of pregnancy) is defined as the presence of total SBA levels above the cut-off value (11 μM) in healthy pregnant women, thus elevation of total SBAs do not necessarily reflect an ICP condition. The aim of the present study was to describe clinical, obstetric, perinatal and biochemical findings, as well as the SBA profile, in pregnant women studied in the third trimester of pregnancy in order to define characteristic patterns of individual bile acids that enable women with ICP to be distinguished from AHP and healthy pregnancies. Free and conjugated ursodeoxycholic (UDCA), cholic (CA), lithocholic (LCA), deoxycholic (DCA) and chenodeoxycholic (CDCA) acids were evaluated by CE (capillary electrophoresis) in 41 patients (15 of them simultaneously by HPLC), in 30 ...

The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance. The protein encoded by this gene is the major canalicular bile salt export pump in man. Mutations in this gene cause a form of progressive familial intrahepatic cholestases which are a group of inherited disorders with severe cholestatic liver disease from early infancy. [provided by RefSeq, Jul 2008 ...
Intrahepatic cholestasis of pregnancy (ICP) is the most prevalent pregnancy-specific liver disease. It occurs mainly in the second or third trimester of pregnancy. It typically resolves after delivery spontaneously but it is associated with an increased risk of adverse fetal outcomes.. The cause of ICP is heterogeneous, pathophysiology is poorly understood and therapies have been empiric. Genetic predispositions, environmental influences, dietary factors and hormonal influences have been studied and cited in the literature.. Comparing with placebo, ursodeoxycholic acid (UDCA) has been shown improvement in treatment of pruritus in previous studies. S-adenosylmethionine, guar gum, activated charcoal, dexamethasone, cholestyramine, etc. are not effective in the treatment of symptoms.. CD4+ T cells are an essential regulators of immune responses and inflammatory diseases. They are also called chief of orchestra cells of immune system. The balance between T helper-(Th)1, Th-2 and Th-17 cells and ...
Background Intrahepatic cholestasis of pregnancy (ICP) is an uncommon obstetric condition characterised by intense maternal pruritis and biochemical abnormality. There is a degree of contention regarding the diagnosis and management of ICP, and currently, there are no nationally accepted guidelines. Aims To conduct a survey of Fellows and Members of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) regarding their diagnosis and management ICP. Methods An online survey of currently practising RANZCOG Fellows and Members, utilising Survey Monkey. Results Thirty percent of those sent the survey responded, comprising approximately 40% of practising obstetricians. Fasting bile acid and serum transaminase elevation in association with the characteristic itch define the disease process for the majority of respondents and also inform management decisions. There was no critical level of bile acid elevation that mandated treatment for the majority of respondents. ...
Intrahepatic cholestasis of pregnancy (ICP) can cause premature delivery and stillbirth. Previous studies have reported that mutations in ABC transporter genes strongly influence the transport of bile salts. However, to date, their effects are still largely elusive. A whole-exome sequencing (WES) approach was used to detect novel variants. Rare novel exonic variants (minor allele frequencies: MAF | 1%) were analyzed. Three web-available tools, namely, SIFT, Mutation Taster and FATHMM, were used to predict protein damage. Protein structure modeling and comparisons between reference and modified protein structures were performed by SWISS-MODEL and Chimera 1.14rc, respectively. We detected a total of 2953 mutations in 44 ABC family transporter genes. When the MAF of loci was controlled in all databases at less than 0.01, 320 mutations were reserved for further analysis. Among these mutations, 42 were novel. We classified these loci into four groups (the damaging, probably damaging, possibly damaging, and
A retrospective case-control study of 21,008 women in Finland has found that those with intrahepatic cholestasis of pregnancy (ICP), an itchy skin condition when bile gets backed up in the liver, are significantly more likely to suffer other liver diseases later in life.
Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy complication whose range has been calculated to be between 0.01 and 15.6% all around the world. We wanted to systematically evaluate the effect and safety of oral herbal medicine on treatment for ICP. Details of the methods could be found in the registered protocol on PROSPERO (CRD42018096013). Trials assessing the effectiveness of herbal medicine for ICP were searched from seven electronic databases from inception to 28th February 2020. RevMan 5.3 software was used to perform all statistical analysis. Meta-analysis, additional analysis, Trial Sequential Analysis (TSA) and Grading of Recommendations Assessment, Development and Evaluation (GRADE) were conducted if data permitted. Totally 43 randomized controlled trials with 3556 patients were included. Meta-analysis showed potential good adjunctive effect of herbal medicine on decreasing the pruritus scores (MD -0.58, 95% CI − 0.79 to − 0.36), the serum TBA scores (MD − 3.99 μmol/L, 95% CI

Cholestasis, benign recurrent intrahepatic, 2 (BRIC2) [MIM:605479]: A disorder characterized by intermittent episodes of cholestasis without progression to liver failure. There is initial elevation of serum bile acids, followed by cholestatic jaundice which generally spontaneously resolves after periods of weeks to months. The cholestatic attacks vary in severity and duration. Patients are asymptomatic between episodes, both clinically and biochemically. {ECO:0000269,PubMed:15300568, ECO:0000269,PubMed:16039748}. Note=The disease is caused by mutations affecting the gene represented in this entry ...
Intrahepatic cholestasis of pregnancy (obstetric cholestasis) is characterised by pruritus, otherwise unexplained deranged liver enzyme levels, and elevated levels of serum bile acid.1 The itching typically subsides almost immediately after delivery and the serum bile acid and liver enzyme levels normalise within a few weeks.2 Intrahepatic cholestasis of pregnancy usually presents in the late second and third trimester3 although it has been reported as early as 6-10 weeks gestation.4. Intrahepatic cholestasis of pregnancy affects about 0.7% of pregnancies in the United Kingdom, varying by ethnic group,5 and usually runs a relatively benign course. The condition is associated with increased rates of spontaneous preterm labour, antepartum passage of meconium, and asphyxial events, but its relation to perinatal mortality is uncertain; early studies reported an increased risk of stillbirth, but some recent studies have cast doubt on the magnitude of the increased risk.1 Interpretation has been ...

From ICP Care:. What is Intrahepatic Cholestasis of Pregnancy (ICP)?. ICP is a group of liver disorders specific to pregnancy which interfere with the flow of bile. Bile is a substance produced by the cells of the liver to aid in digestion of fats. During normal liver function, the bile which is produced is transported out of the cells and into the bile duct by special pumps. During Intrahepatic Cholestasis of Pregnancy, the cells are unable to transport the bile out of the cells normally, which leads to bile acids building up in the blood. Elevated bile acids in the blood are associated with increased risk to the unborn baby. It is important to note that Intrahepatic Cholestasis of Pregnancy is not a single disorder, but a heterogeneous group of many different disorders which all lead to elevated bile acids. This means that the disorder presents very differently in different affected women. 80% of cases are diagnosed in the third trimester, about 10% in the second trimester, and about 10% in ...
