Fulminant diptheretic myocarditis
Abstract:
Five cases of fulminant diphtheritic myocarditis are described. Among them, three had extensive faucial diphtheria. Two had minor ECG abnormalities like low voltage QRS complexes. One of the three cases of severe diphtheria had atrioventricular dissociation, one developed LBBB leading to complete heart block, and the last one had ventricular tachycardia. Three of the five children died; all of them had major ECG abnormalities. Prognosis was also related to SGOT levels.
Insights
Fulminant diphtheritic myocarditis can cause severe heart complications, including heart block and ventricular tachycardia. Early electrocardiogram (ECG) abnormalities and elevated SGOT levels indicate a poorer prognosis in affected children.
Area of Science:
- Cardiology
- Infectious Diseases
- Pediatrics
Background:
- Diphtheria, a bacterial infection, can lead to severe complications beyond the respiratory tract.
- Myocarditis, inflammation of the heart muscle, is a serious but less common manifestation of diphtheria.
Observation:
- This study describes five pediatric cases of fulminant diphtheritic myocarditis.
- Three cases presented with extensive faucial diphtheria, while two had minor electrocardiogram (ECG) abnormalities.
- Severe diphtheria cases exhibited significant cardiac arrhythmias, including atrioventricular dissociation, left bundle branch block (LBBB) with complete heart block, and ventricular tachycardia.
Findings:
- Three out of five children with fulminant diphtheritic myocarditis died.
- All fatal cases exhibited major ECG abnormalities, suggesting their prognostic significance.
- Serum Glutamic Oxaloacetic Transaminase (SGOT) levels were also correlated with patient outcomes.
Implications:
- Fulminant diphtheritic myocarditis carries a high mortality rate, especially in children with significant ECG changes.
- ECG monitoring and SGOT levels are crucial for assessing prognosis in pediatric diphtheria patients.
- Prompt recognition and management of diphtheritic myocarditis are essential for improving survival rates.
