[Antibodies to polysaccharides of group A Streptococcus in the sera of patients with myocarditis].
Antibodies to polysaccharide of streptococcus of group A (A-polysaccharide) were studied in the sera of 95 patients with myocarditis and 105 patients of the control group (congenital heart disease, angina pectoris of effort). In myocarditis patients were found in 51 (52.7%) out of 95 cases (group I); antibodies to A-polysaccharide were absent in 44 (46.3%) of cases (group II). In the control group antibodies were found in 32 (30.4%) out of 105 patients. The number of sera with high level of antibodies to A-polysaccharide is greater in the group of patients with myocarditis, than in the control group (50,98 and 37.5%, respectively). Determination of antibodies to A-polysaccharide can be used as one of the methods for aetiological diagnosis of myocarditis.
