Kawasaki disease pathophysiology
Introduction
Overview
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.

Associated Conditions
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 | |
| Lung | |
| Gastrointestinal tract |
|
| Meninges | |
| Heart | |
| Urinary tract | |
| Pancreas | |
| Lymph nodes |
Gross Pathology
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
