Myocardial dysfunction and thrombocytopenia, rare manifestations of acute post-streptococcal glomerulonephritis: case report

Abstract

In this case report, we present two rare cases of acute post-streptococcal glomerulonephritis with unusual manifestations in the form of myocardial dysfunction and thrombocytopenia. APSGN typically follows Streptococcal infections and is characterized by inflammation of glomeruli. These cases, however, exhibited additional complexities. The first case involved a 12-year-old male with fever, shortness of breath, and cough. He presented with pedal edema, pallor, and hypertension. Laboratory findings revealed thrombocytopenia, anemia, and decreased C3 levels, while echocardiography indicated grade-3 diastolic dysfunction. The second case featured a 5-year-old female with icterus, fever, and body swelling. She had a palpable liver, pleural effusion, and thrombocytopenia. Both cases were diagnosed with APSGN, congestive heart failure, and thrombocytopenia. Thrombocytopenia is a rare finding in APSGN, and its etiology remains debated. Treatment included decongestive therapy and antihypertensive medication. Notably, thrombocytopenia in both cases improved without specific intervention, challenging the necessity of steroids or IVIg therapy. This report illuminates on the atypical presentation of APSGN, highlighting the potential coexistence of glomerulonephritis and thrombocytopenia. It underscores the need for further research to better understand this association and determine appropriate treatment protocols. These cases emphasize the importance of considering diverse clinical manifestations in the context of APSGN, calling for a broader understanding of this condition.
