Overview
The exact pathogenesis of Kawasaki disease is not fully understood. However, it is thought that Kawasaki disease is caused by either environmental, genetic, or viral causes. Kawasaki disease is defined as the systemic inflammation of the medium sized arteries and in multiple organs and tissues, which can lead to associated conditions such as hepatitis, interstitial pneumonitis, abdominal pain, vomiting, diarrhea, gallbladder hydrops, aseptic meningitis, irritability, myocarditis, pericarditis, valvulitis, pyuria, pancreatitis, and lymphadenopathy. On gross pathology, large or giant coronary artery aneurysms, thrombi containing aneurysms, decreases in luminal diameter, stenosis of the lumen and chronic inflamation are noted. On microscopic histopathological analysis of autopsied cases of Kawasaki disease, intracytoplasmic inclusion bodies are frequently observed in ciliated bronchial epithelial cells.
Pathophysiology
Pathogenesis
- The exact pathogenesis of Kawasaki disease is not fully understood.
- It is thought that Kawasaki disease is caused by either environmental, viral or genetic mutations such as, FCGR2A, CASP3, HLAclass II, BLK, IPTKC and CD40.
Genetics
In independent cohort studies, the genes which have been identified to lead to the development of Kawasaki disease include:[1]
| Adapted from the AHA Scientific Statement on the diagnosis, treatment, and long term management of Kawasaki disease[1] | ||||
| Gene | Chromosome Location | Genetic Methods | Validation Populations | Potential Significance |
|---|---|---|---|---|
| FCGR2A[2] | 1q23 | GWAS | European descent, Taiwanese, Koreans, Han Chinese | Low-affinity receptor for Fc fragment of IgG; risk allele has lower binding affinity |
| CASP3[3] | 4q34-35 | Linkage analysis
Candidate gene study |
Japanese, Taiwanese, Koreans, Chinese, Euro-Americans | Mediates apoptosis in immune cells and cardiomyocytes
Risk allele decreases gene transcription |
| HLAclass II[4] | 6p21.3 | GWAS | Japanese, Taiwanese, Koreans | Activation marker for immune cells; antigen presentation |
| BLK[5] | 8p23-22 | GWAS | Japanese, Taiwanese, Koreans | B-cell receptor signal transduction |
| IPTKC[6] | 19q13.2 | Linkage analysis | Japanese, Taiwanese, Koreans, Chinese, Euro- Americans | Negative regulator of calcineurin-NFAT signaling pathway; risk allele increases signaling |
| CD40[7] | 20q12-13.2 | GWAS | Japanese, Taiwanese, Koreans | Risk alleles associated with increased translation |

Associated Conditions
- Inflammation of the coronary arteries leads to the most important clinical outcomes.[8][9]
- Kawasaki disease is defined by the systemic inflammation of the medium-sized arteries, multiple organs and tissues.
- The systemic inflammation of the medium-sized arteries, organs and tissues can lead to the following associated conditions:
| Organ and Tissue | Associated conditions |
|---|---|
| Liver | Hepatitis |
| Lung | Interstitial pneumonitis |
| Gastrointestinal tract | Abdominal pain
Gallbladder hydrops |
| Meninges | Aseptic meningitis |
| Heart | Myocarditis |
| Urinary tract | Pyuria |
| Pancreas | Pancreatitis |
| Lymph nodes | Lymphadenopathy |
Gross Pathology
- On gross pathology, large or giant coronary artery aneurysms, thrombi containing aneurysms, decreases luminal diameter, stenosis of the lumen and chronic inflammation are the usual findings of Kawasaki disease.[10]
- Kawasaki disease mainly involves the muscular arteries and is characterized by the following processes:
- Necrotizing arteritis
- Subacute vasculitis
- Chronic vasculitis
- Luminal myofibroblastic proliferation
Microscopic Pathology
- On microscopic histopathological analysis of autopsied cases of Kawasaki disease, intracytoplasmic inclusion bodies are frequently observed in ciliated bronchial epithelial cells.[11]
