Post-infantile giant cell hepatitis in patients with primary sclerosing cholangitis and autoimmune hepatitis.
In post-infancy, multinucleated giant cell hepatitis is rare. Various conditions and diseases associated with post-infantile giant cell hepatitis have been described, but the pathogenesis remains unknown. In this paper we review the case reports of four patients (3 male, 1 female; aged 22 to 32 years) with primary sclerosing cholangitis and autoimmune hepatitis. The follow-up ranges from five to seven years. All patients showed cholestasis and repeated elevation of hepatic transaminases. Patients with viral infections, metabolic disorders and toxic influences were excluded. Histopathology of liver tissue in all four patients revealed giant cell formation with up to 20 nuclei in 20-70% of al…
Hepatic expression patterns of the large and middle hepatitis B virus surface proteins in viremic and nonviremic chronic hepatitis B.
The envelope of hepatitis B virus consists of large, middle, and small hepatitis B surface proteins. Recent data from in vitro studies suggest that intracellular expression and distribution of the three polypeptides may be variable. These observations in artificial expression systems prompted this analysis of the occurrence and distribution of the three hepatitis B surface proteins in the liver tissue of substantial viremic (hepatitis B virus DNA- and hepatitis B e antigen-positive) and low-viremic or nonviremic (hepatitis B virus DNA-negative, anti-hepatitis B e antigen-positive) carriers by specific monoclonal antibodies against large, middle, and small proteins. Patients with an active f…
Hepatitis A-like non-A, non-B hepatitis: light and electron microscopic observations of three cases.
To date, three types of NANBH have been distinguished by epidemiological, clinical and experimental data. We examined the liver biopsies of three patients with an acute NANBH resembling hepatitis A from the infection route, incubation period and clinical course. The liver biopsies revealed lesions with a portal and periportal predominance, thus also exhibiting parallels with hepatitis A on the histopathological level.
