Kawasaki disease in Malaysia: Biochemical profile, characterization, diagnosis and treatment

Abstract

IntroductionKawasaki disease (KD) is an acute idiopathic systemic vasculitis with a self- limiting course that predominantly affects children under 5 years old, particularly in the East Asian countries. Nevertheless, to date, the data on KD in Malaysia are limited. This study aimed to evaluate the epidemiology, clinical features, treatment, and outcomes of KD among the pediatric patients admitted to Hospital Canselor Tunku Muhriz (HCTM), Kuala Lumpur, Malaysia.MethodA retrospective cohort study of 66,500 pediatric patients presented at HCTM from the year 2004 to 2021 was conducted.Results62 KD cases out of 66,500 pediatric admissions were reported, with a male-to-female ratio of 1.58 to 1. Majority of KD patients (95.0%) were younger than 5 years old. Prior infection was reported in 5 KD patients (8.1%). Apart from the classical features, manifestations of various organ systems including cardiovascular (16.1%), gastrointestinal (43.5%), neurological (1.61%), musculoskeletal (1.61%), and genitourinary (17.7%) systems were observed. There was a significant association between sterile pyuria and coronary artery aneurysm (CAA) (p < 0.05). Interestingly, abnormal liver parameters (p < 0.05) and incomplete KD (p < 0.05) were significantly related to IVIG resistance.DiscussionThe presence of family history, immunological disorder, and previous infection in our KD patients suggested that there is a possibility of genetic, immunological, and infectious roles in the pathophysiology of KD. IVIG resistance is more likely to occur in KD patients with hepatic dysfunction or incomplete KD presentation. These findings highlighted the significant contribution of laboratory parameters to the prognosis of KD, prompting more in-depth research on the KD scoring systems and their relevance in this country.

Concomitant Kawasaki Disease and Rotavirus Infection—More Than Just a Coincidence: A Case Report

“…Rotavirus can act like a superantigen and cause devastating complications, as observed in all the patients reviewed in this study. Furthermore, gastrointestinal symptoms like diarrhoea, vomiting, and abdominal pain are not uncommon in patients with atypical KD [ 31 ]. Therefore, it is important for clinicians to maintain a high level of clinical suspicion of KD in patients presenting with gastrointestinal symptoms and to not delay treatment if clinically indicated.…”
