Concurrent post-streptococcal carditis and glomerulonephritis: serial echocardiographic diagnosis and follow-up.

Abstract

The two non-suppurative post-streptococcal events, acute rheumatic fever and acute glomerulonephritis, rarely occur simultaneously. We describe such a patient, a 16-year-old male who was admitted with fever, agitation and confusion. Blood work-up showed high antistreptolysin O titre, raised serum creatinine and low complement levels. Urinalysis showed RBC casts. Echocardiographic examination demonstrated markedly impaired left ventricular systolic and diastolic function and three large thrombi in the apex. Serial echocardiographic examinations revealed improvement of cardiac function and the resolution of the thrombi and both cardiac and renal function returned to normal after 3 weeks of treatment.
