A novel case of acute glomerulonephritis with concurrent acute non-rheumatic myocarditis following group a streptococcal infection

Streptococcal infection is a common cause of acute glomerulonephritis. Cardiac damage associated with streptococcal infection commonly occurs in acute rheumatic fever. However, cases of acute non-rheumatic streptococcal myocarditis have been reported in recent years. We report a novel case of concurrent acute glomerulonephritis and non-rheumatic myocarditis following streptococcal infection. A good prognosis was achieved with antibiotic and immunosuppressive therapy, indicating that Streptococcus causes cardiorenal syndrome type 5 via an immune-mediated response. A better understanding of post-streptococcal cardiorenal syndrome is warranted to enable the early diagnosis and treatment of affected patients.
