Liver allograft findings of donation after cardiac death versus brain death in recipients with hepatitis C related cirrhosis: a matched histologic comparison.

Hum Pathol 2022 04 25;122:25-31. Epub 2022 Jan 25.

Yale University, School of Medicine, New Haven, CT 06510, USA. Electronic address:

As the demand for organ transplantation increases, utilization of liver allografts of donation after cardiac death (DCD) is becoming increasingly necessary. Although the clinical outcomes of DCD allografts have been well described, the histologic features are not well characterized. Liver biopsies (n = 131) from age-matched DCD (n = 60) and donation after brain death (DBD; n = 71) recipients with hepatitis C virus were compared. Read More

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

Digestive Disease Institute, Cleveland Clinic Foundation, Cleveland, Ohio 44195, USA.

Diseases involving the hepatopancreatobiliary (HPB) system are frequently encountered in patients with inflammatory bowel disease (IBD). Hepatobiliary manifestations constitute some of the most common extraintestinal manifestations of IBD. They appear to occur with similar frequency in patients with Crohn's disease or ulcerative colitis. Read More

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.

Pathological findings in harbour porpoises (Phocoena phocoena) from Norwegian and Icelandic waters.

J Comp Pathol 2006 Feb-Apr;134(2-3):134-42. Epub 2006 Mar 9.

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).

Value of magnetic resonance cholangiography (MRC) in primary sclerosing cholangitis (PSC).

Med Sci Monit 2001 May;7 Suppl 1:114-7

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

Acute and subchronic mammalian toxicity of naphthenic acids from oil sands tailings.

Toxicol Sci 2002 Apr;66(2):347-55

Toxicology Centre, 44 Campus Drive, University of Saskatchewan, Saskatoon, Saskatchewan S7N 5B3, Canada.

Naphthenic acids are the most significant environmental contaminants resulting from petroleum extraction from oil sands deposits. In this study, a mixture of naphthenic acids isolated from Athabasca oil sands (AOS) tailings pond water was used in acute and subchronic toxicity tests with rodents, in order to assess potential risks posed to terrestrial wildlife. Dosages were chosen to bracket worst-case environmental exposure scenarios. Read More

Cytoprotective effects of trimetazidine in carmustine cholestasis.

Exp Toxicol Pathol 1999 Jul;51(4-5):326-9

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

Clinical and pathologic evaluation of chronic Bartonella henselae or Bartonella clarridgeiae infection in cats.

J Clin Microbiol 1999 May;37(5):1536-47

Department of Companion Animal and Special Species Medicine, Pathology, and Parasitology, College of Veterinary Medicine, North Carolina State University, Raleigh, North Carolina 27606, USA.

Human Bartonella infections result in diverse medical presentations, whereas many cats appear to tolerate chronic bacteremia without obvious clinical abnormalities. Eighteen specific-pathogen-free cats were inoculated with Bartonella henselae- and/or Bartonella clarridgeiae-infected cat blood and monitored for 454 days. Relapsing bacteremia did not correlate with changes in protein profiles or differences in antigenic protein recognition. Read More
