Study Notes

Definition

Rheumatic fever (RF) is an inflammatory disease affecting connective tissues, particularly joints and the heart.
Can also involve the CNS, skin, and subcutaneous tissues.

Etiology

RF is a complication of group A beta-hemolytic streptococcal infections, particularly after upper respiratory tract infections.

Epidemiology

Affects males and females equally, typically between ages 5-15.
Occurs in 3% of untreated or inadequately treated streptococcal infections.
Recurrence rate in children with previous attacks is about 50%.
Family history increases occurrence chance by 10%.
More prevalent in overcrowded and impoverished communities.

Clinical Picture and Diagnosis

No singular clinical or laboratory test confirms RF; diagnosis is probable with Jones criteria.
Jones criteria:
- Two major criteria + evidence of prior streptococcal infection.
- One major and two minor criteria + evidence of prior streptococcal infection.

Major Clinical Manifestations

Carditis

Affects 50-70% of patients within the first three weeks of acute RF.
Involves all heart layers: myocardium, endocardium, and pericardium.
Can lead to chronic valvular damage; mild cases may go undetected.
Symptoms include cardiomegaly, tachycardia, rapid sleeping pulse, arrhythmias, and congestive heart failure.

Arthritis

Characterized by red, hot, swollen, tender joints with limited movement, typically affecting large joints.
Symptoms often resolve within a week without treatment or within a day with salicylate therapy.
Does not lead to chronic joint disease.

Rheumatic Chorea

Occurs in about 10% of cases, typically 2-6 months post-infection.
May be the sole manifestation or accompany carditis.

Subcutaneous Nodules

Found in about 1% of cases, mainly in those with severe carditis.
Appear as pea-sized, firm, painless nodules over bony prominences.

Other Investigations

Echocardiography is crucial for suspected RF; detects valvular regurge, cardiac dilatation, decreased function, and pericardial effusion.

Differential Diagnosis

Exclude carditis from viral myocarditis, arthritis from rheumatoid arthritis, chorea from degenerative diseases, and pericarditis from various causes including tuberculosis and viral infections.

Complications

Chronic valvular disease, heart failure, infective endocarditis, arrhythmias, thromboembolism leading to stroke, and potentially death from severe carditis.

Primary Prophylaxis

Early treatment of streptococcal infections is vital to prevent RF.
Prophylactic options include:
- Benzathine penicillin 1,200,000 units IM once.
- Procaine penicillin 400,000 units/day for 10 days.
- Oral penicillin V 125-250mg/dose three times daily for 10 days.
- Erythromycin 40mg/kg/day orally in three divided doses.
