We examined the incidence of toxic shock syndrome in the United States during 2006–2018 among persons

BACKGROUND Kawasaki disease (KD) is a febrile illness of unknown etiology. Patients with Kawasaki disease shock syndrome (KDSS) may present with clinical signs of poor perfusion and systolic hypotension in addition to typical KD features. The United States Centers for Disease Control and Prevention analyzes and interprets large hospitalization databases as a mechanism for conducting national KD surveillance. METHODS The Kids' Inpatient Database (KID), the National (Nationwide) Inpatient Sample (NIS), and the IBM MarketScan Commercial (MSC) and MarketScan Medicaid (MSM) databases were analyzed to determine KD-associated hospitalization rates and trends from 2006 to the most recent year of available data. KD and potential KDSS hospitalizations were defined using International Classification of Disease-Clinical Modification codes. RESULTS For the most recent year, the KD-associated hospitalization rates for children

BACKGROUND Platelet count is considered as a biomarker for the development of coronary artery abnormalities (CAAs) among Kawasaki disease (KD) patients. However, previous studies have reported inconsistent results. We addressed the controversial association of platelet count with CAAs using a large-scale dataset. METHODS A retrospective cohort study was conducted using KD survey data from Japan (2015-2016; n = 25,448). Classifying patients by intravenous immunoglobulin (IVIG) responsiveness, we described the trends in platelet count using the lowest and highest values along with the specific illness days. Multivariate logistic regression analysis was performed to evaluate the association between platelet count and CAAs, adjusting for relevant factors. RESULTS Platelet counts rapidly decreased from admission, reached the lowest count at 6-7 days, and peaked after 10 days. Platelet counts in IVIG non-responders decreased with a lower minimum value than IVIG responders, but subsequently rebounded toward a higher maximum. Compared with patients with normal platelet counts (150-450 × 10/L), patients with abnormally high platelet counts (>450 × 10/L) were more likely to have CAAs at admission (adjusted odds ratio: IVIG responders, 1.50 [95% confidence interval 1.20-1.87] and non-responders, 1.46 [1.01-2.12]). By contrast, IVIG non-responding patients whose counts were below normal (

Background:Kawasaki syndrome (KS) occurs in children

In California, the 2010 annual Kawasaki disease hospitalization rate for children

Background: The present study describes the rate and trends of childhood hospitalizations with Kawasaki syndrome (KS) in the United States. Methods: Retrospective analysis of hospitalizations with KS among children

Objective To describe the incidence and epidemiology of Kawasaki syndrome (KS) in Hawaii. Methods Retrospective analysis of the State Inpatient Database for Hawaii residents hospitalized with KS during 1996 through 2001. Results During 1996 through 2001, 267 persons younger than 18 years of age living in Hawaii were hospitalized with KS; 226 (84.6%) were younger than 5 years of age. The average annual incidence for KS was 45.2 per 100,000 children younger than 5 years of age. The incidence was higher for children younger than 1 year of age than for those 1-4 years of age (74.3 and 37.5 per 100,000). The KS incidence for Asian and Pacific Islander children and for White children was 70.9 and 35.3 per 100,000, respectively. Incidence was highest among Japanese American children living in Hawaii (197.7 per 100,000). Honolulu County had the most KS patients (85.0%) and the highest incidence (53.1 per 100,000) among Hawaii counties. For children younger than 5 years of age hospitalized with KS, the median length of stay was 2 days, and the median hospital charge was $9379. Conclusion During 1996 through 2001, the annual incidence rate for KS among children younger than 5 years of age in Hawaii was the highest in the United States. The incidence among Japanese American children in Hawaii was higher than that among other racial groups in the state and when compared with children living in Japan.
