2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD)-elicited effects on bile acid homeostasis: Alterations in biosynthesis, enterohepatic circulation, and microbial metabolism.

Sci Rep 2017 Jul 19;7(1):5921. Epub 2017 Jul 19.

Department of Biochemistry & Molecular Biology, Michigan State University, East Lansing, MI, 48824, USA.

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a persistent environmental contaminant which elicits hepatotoxicity through activation of the aryl hydrocarbon receptor (AhR). Male C57BL/6 mice orally gavaged with TCDD (0.01-30 µg/kg) every 4 days for 28 days exhibited bile duct proliferation and pericholangitis. Read More

Human fascioliasis is a rare zoonosis in Chile. Clinically it presents with a highly polymorphous group of symptoms that evolve in two periods. The first, acute or a result of hepatic invasion, lasts 2 weeks to 4 months and is characterized essentially by pain in the right hypochondrium and/or epigastrium, continuous fever and painful hepatomegaly.

Syphilis presenting as inflammatory tumors of the liver in HIV-positive homosexual men.

Am J Surg Pathol 2014 Dec;38(12):1636-43

*Department of Pathology, Massachusetts General Hospital and Harvard School of Medicine, Boston, MA †Carolinas Pathology Group, Carolinas Medical Center, Charlotte, NC ‡Infectious Disease Associates of Kansas City, Kansas City, MO.

Syphilis, a sexually transmitted infection caused by the spirochete Treponema pallidum, has seen a resurgence since 2001, particularly in men who have sex with men. Syphilis can affect the liver during the secondary stage as syphilitic hepatitis and during the tertiary stage as gummas. We describe 3 cases of syphilis in human immunodeficiency virus-positive homosexual men that presented as hepatic mass lesions clinically suspected of being malignant tumors. Read More

Idiopathic fibrosing pancreatitis has been associated with Sjögren's syndrome, primary biliary cirrhosis and primary sclerosing cholangitis. This condition frequently develops in childhood and youth, and has also been related to ulcerative colitis and pericholangitis.

A new xenobiotic-induced mouse model of sclerosing cholangitis and biliary fibrosis.

Am J Pathol 2007 Aug 28;171(2):525-36. Epub 2007 Jun 28.

Laboratory of Experimental and Molecular Hepatology, Division of Gastroenterology and Hepatology, Department of Medicine, Medical University Graz, Austria.

Xenobiotics and drugs may lead to cholangiopathies and biliary fibrosis, but the underlying mechanisms are largely unknown. Therefore, we aimed to characterize the cause and consequences of hepatobiliary injury and biliary fibrosis in 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC)-fed mice as a novel model of xenobiotic-induced cholangiopathy. Liver morphology, markers of inflammation, cell proliferation, fibrosis, bile formation, biliary porphyrin secretion, and hepatobiliary transporter expression were studied longitudinally in DDC- and control diet-fed Swiss albino mice.

Forschungs- und Technologiezentrum Westküste, Christian-Albrechts-Universität zu Kiel, 25761 Buesum, Germany.

A study of 37 by-caught harbour porpoises from Icelandic and Norwegian waters showed that most were in good or moderate nutritional condition and none was severely emaciated. Mild infection with lungworms (Halocercus invaginatus, Pseudalius inflexus, Torynurus convolutus) was found in 84% of the Icelandic and 91% of the Norwegian animals, usually associated with bronchopneumonia which was rarely severe. Most (91%) of the animals had parasites in the stomach and intestine (Anisakis simplex, Contracaecum osculatum, Pholeter gastrophilus), and Campula oblonga was present in the liver and pancreas of 88 and 21%, respectively.

Cholangitis: a histologic classification based on patterns of injury in liver biopsies.

Pathol Res Pract 2005 ;201(8-9):565-72

Department of Pathology, University of Massachusetts Medical School, Worcester, MA 01655, USA.

Inflammatory disorders of the biliary tract present difficult diagnostic problems in liver needle biopsies. The aim of this study was to perform a detailed histologic analysis of liver biopsies from patients with biliary tract disorders, classify them by pattern of inflammation, and determine the accuracy of the histologic classification by clinical follow-up. Percutaneous liver needle biopsies from the surgical pathology files of UmassMemorial Healthcare (UMMHC) from 2000 to 2003 with a diagnosis suggesting a biliary tract process (n = 32) and four biopsies from cases with systemic non-biliary tract disorders were analyzed for multiple histologic features and classified as one of five patterns: acute cholangitis/pericholangitis (ACP), lymphocytic cholangitis (LC), granulomatous (G), ductopenia (D), or non-specific (NS).

IgG4-related sclerosing cholangitis with and without hepatic inflammatory pseudotumor, and sclerosing pancreatitis-associated sclerosing cholangitis: do they belong to a spectrum of sclerosing pancreatitis?

Am J Surg Pathol 2004 Sep;28(9):1193-203

Department of Human Pathology, Kanazawa University Graduate School of Medicine, Kanazawa, Japan.

Sclerosing cholangitis (SC) is a heterogeneous disease entity. Different etiologies such as choledocholithiasis, biliary tumor, or pericholangitis can manifest as SC. Hepatic inflammatory pseudotumor (IP) is rarely associated with SC (sclerosing cholangitis associated with hepatic inflammatory pseudotumor; SC-hepatic IP), but sclerosing pancreatitis (SP) is not infrequently associated with bile duct lesions (sclerosing pancreatitis-associated sclerosing cholangitis; SP-SC).

Department of Infectious Diseases, Medical University in Gdańsk, ul. Smoluchowskiego 18, 80-214 Gdańsk, Poland.

Background: Magnetic resonance cholangiography is a relatively new method, hence it has not gained a proper status yet in the diagnostic algorithm in patients with bile duct diseases. Many authors believe that MRC is an effective method for the visualisation of bile ducts. The aim of the study is to evaluate MRC usefulness in patients with PSC. Read More

Cytoprotective effects of trimetazidine in carmustine cholestasis.

Department of Biochemistry, Ege Univ. Medical School, Bornova, Izmir, Turkey.

Carmustine [1 ,3-bis(2-chloroethyl)-1-nitrosurea (BCNU)] is an antitumour agent, however, its usefulness has been limited by a side effect; which involves pericholangitis and intrahepatic cholestasis. The primary effects of cholestasis is well known; bile flow retention, intracellular Ca++ accumulation and acidosis although it may lead to hepatotoxicity by dose-dependent manner. Recent studies provide evidence that lipoperoxidation (LPO) and alterations in the antioxidant system may significantly contribute to BCNU induced hepatotoxicity. Read More

Many centers perform biopsies on transplanted livers annually to assess allograft function because serum biochemical tests do not always correlate with histological findings. Although criteria exist for diagnosing acute cellular rejection, no similar criteria exist to describe the histopathological changes observed in the "normal" liver of an immunosuppressed but healthy child. The purpose of this study was to define the histopathological changes in the allografted livers of healthy children who have undergone transplantation and to evaluate them during long-term follow-up.

Known risk factors for the development of dysplasia and cancer in ulcerative colitis (UC) patients are: 1) increased extent and duration of disease and 2) increased age at symptom onset. This case-control study was performed to determine whether cholestatic liver disease is associated with neoplastic transformation.

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, Minnesota 55905.

Current evidence suggests that PSC may affect the entire biliary system from interlobular bile ducts to the ampulla of Vater. If the affected bile ducts are too small for cholangiographic identification, the best designation for the condition is small-duct PSC; cholangiographically identifiable duct changes are the hallmark of large-duct PSC. The term "small-duct PSC" should replace the name pericholangitis because that designation lacks a clear definition. Read More

Nitrosoureas lomustine, carmustine and fotemustine induced hepatotoxic perturbations in rats: biochemical, morphological and flow cytometry studies.

Eur J Cancer 1991 ;27(5):630-8

Laboratoire d'anatomo-pathologie et de cytologie pathologique, Hôpital Charles Nicolle, C.H.U., Rouen, France.

Chloroethylnitrosoureas are reactive compounds that are highly effective against malignant neoplasms in humans and animals. The most widely used nitrosoureas, lomustine and carmustine, are known to be hepatotoxic and to induce pericholangitis and intrahepatic cholestasis, which in the long term lead to cholangiolysis and biliary cirrhosis. However, the nitrosourea fotemustine has proved to be non-hepatotoxic at 20 mg/kg and 50 mg/kg. Read More
