Double infections with hepatitis A and B viruses.

Ten (2.8%) asymptomatic carriers of HBsAg and four (1.1%) patients with acute hepatitis B virus (HBV) infection were detected among 356 adults with acute viral hepatitis A (HAV) consecutively admitted to the Athens Hospital for Infectious Diseases from May 1981 to March 1984.

How often does chronic liver disease follow acute hepatitis B in adults?

The risk of developing the chronic hepatitis B surface antigen (HBsAg) carrier state after primary acute hepatitis B virus infection was examined in a prospective study of adults with acute icteric (clinically apparent) viral hepatitis. Enzyme immunoassay for IgM antibody to hepatitis B core antigen (IgM anti-HBc) was positive in 176 (93.1%) and negative in 13 (6.

Susceptibility to autoxidation of lipids of paroxysmal nocturnal hemoglobinuria (PNH)-like red cells.

The susceptibility to autoxidation of red cell lipids was studied before and after transformation of normal red cells to PNH-like erythrocytes. The transformation was effected by treatment of the red cells with the sulfydryl compounds D-penicillamine (DP) and N-acetyl-L-cysteine (NAC). The autoxidation was induced by incubating the cells with H2O2 and was estimated by measuring the generated malonyl dialdehyde.
