Diagnostic criteria for KD.
| Clinical Presentation | <6 months old N (%) | ≥6 months old N (%) | p-valued and OR (95% CI) |
|---|---|---|---|
| Rash | 30 (83.3%) | 814 (87.2%) | 0.45 |
| Conjunctival injection | 29 (80.6%) | 812 (86.9%) | 0.31 |
| Oral changesa | 27 (75%) | 865 (92%) | 0.0023* OR = 0.26 (0.12 to 0.58) |
| Cervical lymphadenopathya | 13 (37.1%) | 627 (67.6%) | 0.0004* OR = 0.28 (0.14 to 0.55) |
| Extremity changes | 20 (57.1%) | 694 (74.6%) | 0.029* OR = 0.45 (0.23 to 0.88) |
| Complete KDb, N (%) | 16 (44.4%) | 720 (76.6%) | <0.0001* OR = 0.24 (0.13 to 0.47) |
| Incomplete KDc, N (%) | 20 (55.6%) | 220 (23.4%) | <0.0001* OR = 4.1 (2.1 to 8.0) |
These clinical features are based on the American Heart Association criteria for KD. Oral changes include erythematous oropharynx or lips or strawberry tongue. Cervical lymphadenopathy is unilateral and is a lymph node at least 1.5 cm.
Complete KD as defined by the AHA with at least 4 of the 5 clinical criteria.
Incomplete KD by laboratory evaluation is defined the AHA with <4 clinical criteria and laboratory inflammation (ESR ≥ 40 mm/hr or CRP ≥ 3 mg/dl with ≥ 3 supplementary labs elevated: albumin levels of <3.0 g/dL, anemia for age, elevation of ALT level, >450,000 platelets per mm3 after the seventh day, white blood cell count of >15,000 cells per mm3, and >10 white blood cells per high-power field in the urine).
Fisher's exact test was used to test differences in count data.
Indicates statistical significance (p < 0.05).
