[The secretory and systemic humoral immune response to polysaccharide A in patients with rheumatism]

The level of sIgA saliva antibodies and Ig(M + G + A) serum antibodies to group polysaccharide A of streptococcus was studied in healthy donors and patients with streptococcal angina and rheumatic fever. It was shown that an elevated level of secretory and serum antibodies to polysaccharide A was registered in patients with angina and rheumatic fever reliably more frequently than in healthy donors. Independence of local and systemic humoral immune response to polysaccharide A was established.
