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.

Observations on morning and afternoon glucose tolerance: differences between sexes.

One hundred non-obese and non-diabetic individuals, 50 men and 50 women, were submitted to oral glucose tolerance tests performed in the morning and in the afternoon on different days. Although great individual variations were noted in both sexes, in men the mean blood sugar (BS) values did not significantly differ between the two tests; in women, however, the mean values after glucose loading were significantly higher during the afternoon test. By dividing the test population into those aged 50 and below and those over 50 it was found that only the group of younger women showed significant differences between the two tests with higher mean BS values during the afternoon test.

Brucellosis in two thalassaemic patients infected by blood transfusions from the same donor.

Brucellosis was diagnosed in two polytransfused, thalassaemic patients who had received blood containing brucella agglutinins from an asymptomatic donor. In one of the patients the onset of the disease simulated infectious mononucleosis. Despite the fact that both cases were splenetomized, the course of illness was not life threatening.
