Abstract
The serum antihistone antibody (AHA) positivity of patients with various autoimmune diseases was compared with their positive reaction for antinuclear factor, rheumatoid factor, lupus erythematosus factor, cryoglobulin, immunocomplex, C-reactive protein, total protein, gamma globulin, IgG and IgM. In non-drug-induced SLE cases the predictive value of the AHA test was not higher than that of the other tests. It was striking that in 42% of patients with non-autoimmune disease aged over 70 the AHA test was positive. Elevated IgM values were recorded in about 70% of positive AHA samples.
