Pathogenesis of steatorrhea in primary biliary cirrhosis

Stephen J. Lanspa, Albert T. H. Chan, J. Sumner Bell, Vay Liang W. Go, E. Rolland Dickson, Eugene P. Dimagno – 1 September 1985 – To investigate the pathophysiology of steatorrhea in primary biliary cirrhosis, the severity of steatorrhea, small bowel histology and function, cholestasis, exocrine pancreatic secretion and liver histology were studied. Twenty‐four primary biliary cirrhotic patients had a quantitative stool fat collection, serum bilirubin and alkaline phosphatase and liver biopsies.

Hepatocellular carcinoma in young, mentally retarded HBsAg carriers without cirrhosis

Ghanshyam Lohiya, Hubert Pirkle, John Hoefs, Sunita Lohiya, Vinh Trong Ngo – 1 September 1985 – In a Californian institution for the mentally retarded, surveillance by autopsy of all deaths (n = 138) identified three cases of hepatocellular carcinoma. Hepatocellular carcinoma cases occurred in young (mean age = 26 years) male carriers of HBsAg and were not associated with cirrhosis. They were of the nonfibrolamellar oncocytic type and were rapidly fatal. Hepatocellular carcinoma incidence in HBsAg carriers was estimated to be 246 times greater than United States males.

Hepatitis B virus DNA, HBeAg and delta infection during the course from acute to chronic hepatitis B virus infection

Kim Krogsgaard, Jan Aldershvile, Peter Kryger, Poul Andersson, Jens Ole Nielsen, Bengt Göran Hansson, The Copenhagen Hepatitis Acuta Programme – 1 September 1985 – The presence of hepatitis B virus DNA in serum was determined in 57 unselected patients during the course from acute to chronic hepatitis B infection. Forty‐six (81%) patients were hepatitis B virus DNA‐positive in the first available serum sample. Generally, hepatitis B virus DNA was cleared before or at the same time as HBeAg, but in two patients (4%), hepatitis B virus DNA could be demonstrated after HBeAg clearance.

A randomized comparison of metoclopramide and domperidone on plasma aldosterone concentration and on spironolactone‐induced diuresis in ascitic cirrhotic patients

Agesilao D‐Arienzo, Gabriella Ambrogio, Pasqualina Di Siervi, Enzo Perna, Giovanni Squame, Gabriele Mazzacca – 1 September 1985 – The effect of metoclopramide and domperidone, two dopamine antagonists, administered to cirrhotic patients with ascites and secondary hyperaldosteronism, was examined to evaluate the changes in plasma aldosterone levels and in spironolactone‐induced diuresis.

Hepatic mitochondrial oxidative metabolism in rats with chronic dietary iron overload

Bruce R. Bacon, Chanho H. Park, Gary M. Brittenham, Rosemary O‐Neill, Anthony S. Tavill – 1 September 1985 – We examined the effects of chronic dietary iron overload on hepatic mitochondrial oxidative metabolism. Experimental iron overload was produced by feeding rats a chow diet supplemented with carbonyl iron over a 7‐week period. Biochemical and histologic evaluations of liver tissue confirmed moderate degrees of hepatic parenchymal iron overload.

Function of the autonomic nervous system in patients with hepatic encephalopathy

Kurt Lenz, Heide Hörtnagl, Dieter Magometschnigg, Gunter Kleinberger, Wilfred Druml, Anton Laggner – 1 September 1985 – To obtain further pathophysiological details concerning the development of cardiovascular disturbances in severe liver disease, the state of the autonomic nervous system, the function of the baroreceptor reflex pathway and the responsiveness of the cardiovascular system to noradrenaline, angiotensin II and isoprenaline were investigated in 11 patients with hepatic encephalopathy and in 10 healthy control subjects.

Mitochondrial antibodies in primary biliary cirrhosis: Species and nonspecies specific determinants of M2 antigen

Jutta Lindenborn‐Fotinos, Harold Baum, Peter A. Berg – 1 September 1985 – Sera from patients with primary biliary cirrhosis reacted with four major bands in beef heart mitochondria and ATPase extract when analyzed by immunoblot after sodium dodecyl sulfate‐polyacrylamide gel electrophoresis. These four immunologically reactive bands corresponded to protein bands with molecular weights of about (a) 80,000; (b) 63,000; (c) 56,000; and (d) 43,000 to 46,000. An additional immunoreactive band was found with some high‐titered primary biliary cirrhosis sera at 36,000.

Regulation of the human immune response to HBsAg: Effects of antibodies and antigen conformation in the stimulation of helper T cells by HBsAg

Esteban Celis, Ikunoshin Kato, Richard W. Miller, Tse Wen Chang – 1 September 1985 – The role of accessory cells (antigen‐presenting cells) in binding HBsAg in the response of human T cells to this antigen was studied. Antibodies to HBsAg of IgG class increased significantly the amount of HBsAg that was captured and internalized by accessory cells in vitro. On the other hand, antibodies to HBsAg of IgM class or the F(ab‐)2 and Fab fragments of antibodies to HBsAg of IgG class did not modify the amount of HBsAg associated to these cells.
