Changes in bile acid composition in patients with primary biliary cirrhosis induced by ursodeoxycholic acid administration

Andrea Crosignani, Mauro Podda, Pier Maria Battezzati, Emanuela Bertolini, Massimo Zuin, David Watson, Kenneth D. R. Setchell – 1 December 1991 – We describe a detailed study of the effects of ursodeoxycholic acid administration on bile acid composition of the serum and bile of patients with primary biliary cirrhosis.

Excellent prognosis in wilsonian chronic active hepatitis: New data or an article of faith?

Philip J. Johnson, Roger Williams – 1 December 1991 – Twenty of 320 patients with Wilson's disease initially presented with chemical and laboratory features of chronic active hepatitis, confirmed histologically in 17. When first seen, cirrhosis was present in all 20 and was complicated by ascites and/orjaundice in 11. Within 1 week to 8 years of the onset of overt liver disease the diagnosis of Wilson's disease was established, and treatment with D‐penicillamine was promptly initiated in 19 patients. One man refused treatment and died 4 months later.

Immunohistochemical demonstration of pancreatic α‐amylase and trypsin in intrahepatic bile ducts and peribiliary glands

Tadashi Terada, Yasuni Nakanuma – 1 December 1991 – Epithelia of intrahepatic bile ducts and peribiliary glands were immunohistochemically examined for pancreatic α‐amylase and trypsin in 54 normal autopsied livers. α‐Amylase was evaluated with a polyclonal antibody, and trypsin was assayed with both polyclonal and monoclonal antibodies. α‐Amylase was observed in large ducts, septal ducts and peribiliary glands in most livers and was seen in interlobular ducts in seven (13%) livers.

Complications of liver biopsy in liver transplant patients: Increased sepsis associated with choledochojejunostomy

Mark E. Bubak, Michael K. Porayko, Ruud A. F. Krom, Russell H. Wiesner – 1 December 1991 – We investigated the incidence and types of liver biopsy complications in our first 160 consecutive liver transplantations. A significant complication was identified by the need for therapeutic intervention (for example, hospitalization, transfusion, intravenous fluids, chest tube, surgery or antibiotic therapy). A total of 950 percutaneous hepatic allograft biopsies were performed in 136 patients (mean = 6.9 biopsies/graft; range = 1 to 29).

IgA class antibodies to hepatitis delta virus antigen in acute and chronic hepatitis delta virus infections

Ian G. McFarlane, Kanchan Chaggar, Susan E. Davies, Heather M. Smith, Graeme J. M. Alexander, Roger Williams – 1 December 1991 – Sera from 31 patients with chronic hepatitis delta virus infection and 18 patients with acute hepatitis delta virus infection were examined for IgA class antibodies to this virus using a newly developed enzyme immunoassay. IgA antibody to hepatitis D virus was detected in 21 (67.7%) of 31 patients with chronic delta viral hepatitis, but in only 1 (5.6%) of the 18 patients with acute infection (p < 0.0005).

Kupffer cells from carbon tetrachloride–injured rat livers produce chemotactic factors for fibroblasts and monocytes: The role of tumor necrosis factor‐α

Juan Armendariz‐Borunda, Jerome M. Seyer, Arnold E. Postlethwaite, Andrew H. Kang – 1 November 1991 – Conditioned media from cultured Kupffer and mononuclear macrophagic cells obtained 48 hr after CCl4 administration to rats contains chemotactic factors for human skin fibroblasts and human monocytes. The chemotactic mediator for fibroblasts was approximately 17 kD and was more prominent at early stages of culture. It induced a dose‐dependent chemotactic response in fibroblasts.

Failure to detect hepatitis C virus genome in human secretions with the polymerase chain reaction

Henry H. Hsu, Teresa L. Wright, Daniel Luba, Mary Martin, Stephen M. Feinstone, Gabriel Garcia, Harry B. Greenberg – 1 November 1991 – Although hepatitis C infection has been clearly demonstrated to be transmitted through blood products or blood contamination, most cases of sporadic hepatitis C infection are unassociated with parenteral risk factors, and it is unclear how infection might be acquired by nonparenteral means. One potential mode of nonparenteral transmission is through body secretions.
