Abstract:
Rheumatic fever resulting from group A beta-haemolytic Streptococcus infection continues to be a prevalent disease and an important cause of morbidity and mortality in developing countries. Molecular mimicry and CD4 T lymphocytes, interleukins and adhesion molecules play a crucial role in the pathogenesis of this disease. Arthritis, followed by carditis and chorea, are the main manifestations of the disease. Evidence of asymptomatic carditis has been increasing; however, abnormality identified by echo-Doppler evaluation is not considered as a criterion for diagnosis of rheumatic carditis. Benzathine penicillin is still the best therapeutic option for the treatment of streptococcal infection and secondary prophylaxis, due to its efficacy and low cost.
Insights
Rheumatic fever, a significant global health issue, is caused by Streptococcus bacteria. Early diagnosis and treatment with benzathine penicillin are crucial for managing this condition and preventing long-term complications.
Area of Science:
- Immunology
- Infectious Diseases
- Cardiology
Background:
- Rheumatic fever remains a major cause of illness and death, particularly in developing nations.
- Group A beta-haemolytic Streptococcus infection triggers the disease, involving complex immune responses.
- Key pathogenic factors include molecular mimicry, CD4 T lymphocytes, interleukins, and adhesion molecules.
Purpose of the Study:
- To review the pathogenesis, clinical manifestations, and management of rheumatic fever.
- To highlight the role of immune components in disease development.
- To emphasize current therapeutic strategies and diagnostic considerations.
Main Methods:
- Literature review of rheumatic fever pathogenesis and clinical features.
- Analysis of diagnostic criteria and therapeutic options.
- Examination of the role of specific immune molecules and cells.
Main Results:
- Arthritis, carditis, and chorea are primary clinical presentations.
- Asymptomatic carditis is increasingly recognized but not a diagnostic criterion.
- Echo-Doppler findings for carditis lack diagnostic inclusion.
Conclusions:
- Benzathine penicillin is the preferred treatment for streptococcal infections and secondary prophylaxis.
- Effective management relies on prompt treatment and prophylaxis due to penicillin's efficacy and affordability.
- Understanding the immune mechanisms is vital for future therapeutic advancements.
