Overview
If left untreated, the symptoms will eventually relent, but coronary artery aneurysms will not improve, resulting in a significant risk of death or disability due to myocardial infarction. If treated in a timely fashion, this risk can be mostly avoided and the course of illness cut short. Patients with Kawasaki disease may progress to develop long term cardiovascular illness such as coronary artery disease, and pre-mature atherosclerosis. Common complications of Kawasaki disease include vasculitis and coronary artery aneurysms. Prognosis is generally excellent and the mortality rate of patients with Kawasaki disease is approximately 2%.
Natural History, Complications, and Prognosis
Natural History
- If left untreated, the symptoms will eventually relent, but coronary artery aneurysms will not improve, resulting in a significant risk of death or disability due to myocardial infarction.
- If treated in a timely fashion, this risk can be mostly avoided and the course of illness cut short.
- Patients with Kawasaki disease may progress to develop long term cardiovascular illness such as coronary artery disease, and pre-mature atherosclerosis.[1]
Complications
- The cardiac complications are, by far, the most important aspect of the Kawasaki disease.[2][3]
- Vasculitic changes in the coronary arteries
- Coronary artery aneurysms
- These aneurysms can lead to myocardial infarction even in young children. Overall, about 10–18% of children with Kawasaki disease develop coronary artery aneurysms, with much higher prevalence among patients who are not treated early in the course of illness.
- Kawasaki disease is the most common cause of acquired heart disease among children in the United States.
- The other complications associated with Kawasaki disease are: [4]
| 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 |
Prognosis
- With early treatment, rapid recovery from the acute symptoms can be expected and the risk of coronary artery aneurysms greatly reduced. Untreated, the acute symptoms of Kawasaki disease are self-limited, but the risk of coronary artery involvement is much greater. Patients who have had Kawasaki disease should have an echocardiogram initially every few weeks, and then every 1–2 years to screen for progression of cardiac involvement.
- Overall, about 2% of patients die from complications of coronary vasculitis.
- It is also not uncommon that a relapse of symptoms may occur soon after initial treatment with IVIG.
- This usually requires re-hospitalization and retreatment. Treatment with IVIG can cause allergic and non-allergic acute reactions, aseptic meningitis, fluid overload and rarely other serious reactions.
- Aspirin may increase the risk of bleeding from other causes and may be associated with Reye's syndrome.
- Overall, life-threatening complications resulting from therapy for Kawasaki disease are exceedingly rare, especially compared with the risk of non-treatment.
