Humoral immunity to streptococcal antigen in acute and chronic glomerulonephritis.
A study was carried out to verify the clinical usefulness of the elaborated method for the measurement of antistreptococcal antibody in revealing the streptococcal etiology of glomerulonephritis. In 158 patients with glomerulonephritis antistreptococcal antibody (ASA), circulating immune complexes (CIC) and haemolytic activity of the complement were measured. On the basis of immune complex formation it has been concluded that streptococcal infection may cause glomerulonephritis. Serial determinations of ASA and CIC are helpful in establishing the streptococcal etiology of glomerulonephritis and in monitoring the course of the disease.
