Kawasaki Disease

Kawasaki Disease (KD) is an acute, self-limiting systemic vasculitis primarily affecting medium-sized arteries, most notably the coronary arteries. It is the leading cause of acquired heart disease in children in developed nations. If left untreated, it may result in coronary artery aneurysms.

The exact cause remains unknown but is hypothesized to involve an infectious or environmental trigger in genetically susceptible children, resulting in an abnormal immune response. No single pathogen has been identified.

KD involves widespread inflammation of the tunica media of medium-sized arteries. Intense activation of the immune system leads to cytokine storm (TNF-α, IL-1, IL-6), causing endothelial cell damage, infiltration by lymphocytes and macrophages, and subsequent degradation of internal elastic laminae, leading to vessel wall weakening and aneurysm formation.

Most common in children under 5 years of age. It has a higher incidence in children of East Asian descent (particularly Japan, Korea, and China). Males are affected more frequently than females (ratio 1.5:1).

Age (typically <5 years), male gender, Asian ethnicity, familial history of Kawasaki disease, and seasonal fluctuations (often peaking in winter and spring).

A. Early Symptoms
Fever lasting >5 days, irritability, malaise. B. Common Symptoms
Bilateral non-exudative conjunctivitis, polymorphous rash, strawberry tongue, erythema of palms/soles, cervical lymphadenopathy. C. Advanced Symptoms
Peeling of skin (desquamation) of the fingers and toes, joint pain, abdominal pain. D. Emergency Symptoms
Signs of cardiac compromise: chest pain, dyspnea, tachycardia, hypotension.

Tachycardia, conjunctival injection, pharyngeal erythema, indurated edema of hands/feet, rash (maculopapular or scarlatiniform), tender cervical lymph nodes (>1.5 cm).

A. Clinical Assessment: Based on fever >5 days plus 4 of 5 clinical criteria.
B. Laboratory Testing: CBC, CRP/ESR, LFTs, Urinalysis.
C. Imaging Studies: Echocardiography is the gold standard.
D. Functional Tests: ECG.
E. Biopsy Findings: Rarely indicated; shows necrotizing arteritis.
F. Genetic Testing: Generally not utilized clinically.
G. Differential Diagnosis: Scarlet fever, Measles, Stevens-Johnson Syndrome, MIS-C.

Test Name: Erythrocyte Sedimentation Rate (ESR)
Type: Blood Test
Purpose: Assess systemic inflammation
Expected Findings: Markedly elevated
Interpretation: Indicates active vasculitis Test Name: Complete Blood Count (CBC)
Type: Blood Test
Purpose: Evaluate hematologic markers
Expected Findings: Leukocytosis, normocytic anemia, thrombocytosis (in second week)
Interpretation: Consistent with systemic inflammatory response

Echocardiography: Purpose: Monitor coronary artery morphology. Findings: Aneurysms, ectasia, or pericardial effusion. Importance: Detection of coronary damage to initiate secondary prevention.

Distinguished from Scarlet Fever (positive Streptococcal culture), Measles (presence of cough/coryza), and MIS-C (which typically involves deeper cardiovascular collapse and older age).

Coronary artery aneurysms, myocardial infarction, myocarditis, rhythm disturbances, valvular regurgitation.

A. Lifestyle Modifications: None specific.
B. Preventive Measures: Early detection and therapy.
C. Medical Treatment: Intravenous Immunoglobulin (IVIG) and high-dose Aspirin.
D. Surgical Treatment: Coronary artery bypass graft (CABG) for severe stenotic disease.
E. Interventional Procedures: Stent placement or thrombolysis for thrombosis.
F. Rehabilitation: Post-cardiac event physical therapy.
G. Emergency Management: Pulse dose steroids for IVIG-resistant cases.

Good with early IVIG treatment (within 10 days). Untreated, 20-25% develop coronary artery damage. Long-term follow-up required for those with aneurysms.

No primary prevention. Secondary prevention involves long-term low-dose aspirin and monitoring for high-risk patients.
