What Is the Most Severe Manifestation of Rheumatic Fever in Children?

The most severe clinical manifestation of rheumatic fever in children is carditis, which includes acute rheumatic carditis—encompassing myocarditis, pericarditis, and endocarditis—as well as chronic valvular heart disease, such as rheumatic heart disease. Nearly all children with rheumatic fever exhibit cardiac involvement to some degree, presenting symptoms including pallor, excessive sweating, epistaxis, dyspnea, precordial pain, and potentially heart failure. These characteristic features of carditis represent the most severe clinical presentation of rheumatic fever in children.

There is no definitive cure for this condition. The overarching treatment principles include early diagnosis, appropriate therapy, and prevention of irreversible heart disease resulting from disease progression. In addition to glucocorticoid therapy, combination treatment with angiotensin-converting enzyme (ACE) inhibitors, digitalis, diuretics, and agents that reduce cardiac workload is recommended. Patients with chronic congestive heart failure require long-term oral digitalis therapy, with regular monitoring of serum drug concentrations and timely dose adjustments as needed. Specific medications should be administered strictly according to physician instructions.

It is advisable to engage in regular physical exercise to enhance cold resistance and prevent upper respiratory tract infections, both of which play a positive role in preventing rheumatic diseases. We hope this response has been helpful to you!
