Insights
Kawasaki disease shock syndrome (KDSS) is a severe condition that can be difficult to diagnose. KDSS patients present with more prominent inflammatory markers and a higher risk of coronary artery dilatation compared to typical Kawasaki disease (KD).
Area of Science:
- Pediatric Cardiology
- Critical Care Medicine
- Infectious Diseases
Background:
- Kawasaki disease shock syndrome (KDSS) is a severe complication of Kawasaki disease (KD).
- KDSS diagnosis can be challenging due to atypical presentations.
- Understanding KDSS is crucial for timely intervention and improved outcomes.
Purpose of the Study:
- To identify clinical presentations, risk factors, and outcomes of children with KDSS.
- To compare KDSS patients with typical KD patients without shock.
Main Methods:
- A retrospective case-control study was conducted.
- Case patients: children hospitalized with KD and hypotension, sepsis, or shock (2001-2011).
- Control patients: season-matched children with KD and normal blood pressure.
Main Results:
- Nine KDSS patients and 27 controls were identified.
- KDSS patients had lower initial KD diagnosis rates (22.2%) and higher coronary artery dilatation risk (77.8%).
- Risk factors included elevated neutrophils, CRP, and lower platelets; treatments involved aspirin, IVIG, fluids, and vasoactive infusions.
Conclusions:
- KDSS may present atypically and be misdiagnosed initially.
- KDSS patients exhibit heightened early inflammatory markers.
- There is an increased risk of coronary artery dilatation in KDSS patients.
Background:
Kawasaki disease shock syndrome (KDSS) is a severe condition related to Kawasaki disease (KD), and sometimes it is difficult to diagnose. This is a case-control study to ascertain the clinical presentations, risk factors, and clinical outcomes of children who had KDSS.
Materials And Methods:
Children who were hospitalized during 2001-2011 with the diagnosis of KD combined with hypotension, sepsis, or shock were retrospectively reviewed and were defined as case patients. For each case patient, three season-matched patients diagnosed as having KD with normal blood pressure were identified to serve as control patients. Demographic characteristics, clinical presentations, laboratory features, therapies, and outcomes were analyzed.
Results:
Nine KDSS patients and 27 control patients were identified. The average age of patients with KDSS was 3.2 ± 3.2 years. Compared with controls, KDSS patients were less likely to have a diagnosis of KD at admission (22.2% vs. 66.7%) and had a higher risk of coronary artery dilatation (77.8% vs. 11.1%). Risk factors for KDSS included higher neutrophil counts and proportions of bands, higher C-reactive protein (CRP), and lower platelet counts. All case patients received aspirin therapy; eight patients received intravenous immunoglobulin therapy, with two receiving more than one course. Seven KDSS patients required fluid resuscitation, and eight patients required vasoactive infusions.
Conclusion:
Patients with KDSS may have uneven clinical course and may be misdiagnosed in the beginning. They may have more prominent inflammatory markers in the early phase and higher risk of coronary artery dilatation.

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
