RESUMO
OBJECTIVE: The use of IVIG plus high- or low-dose aspirin for the initial treatment of Kawasaki disease remains controversial. The aim of this study was to evaluate the efficacy of IVIG plus high-dose aspirin compared with IVIG plus low-dose aspirin in the treatment of Kawasaki disease. METHODS: Studies related to aspirin therapy for Kawasaki disease were selected by searching the databases of Medline (PubMed), Embase and the Cochrane Library before March 2019. Statistical analyses were performed by using a Review Manager Software package and STATA v.15.1. RESULTS: Eight retrospective cohort studies, characterizing 12 176 patients, were analysed. Overall, no significant difference was found in the incidence of coronary artery abnormalities between the high- and low-dose aspirin groups [relative risk (RR) 1.15; 95% CI: 0.93, 1.43; P = 0.19; random-effects model]. The patients treated with high-dose aspirin had slightly faster resolution of fever [mean difference (MD) -0.30; 95% CI: -0.58, -0.02; P = 0.04; random-effects model]. but the rates of IVIG resistance (RR, 1.26; 95% CI: 0.55, 2.92; P = 0.59; random-effects model) and days in hospital (MD, 0.22; 95% CI: -0.93, 1.37; P = 0.71; random-effects model) were similar between the two groups. CONCLUSION: Low-dose aspirin plus IVIG might be as effective as high-dose aspirin plus IVIG for the initial treatment of Kawasaki disease. Considering that high-dose aspirin may cause more adverse reactions than low-dose aspirin, low-dose aspirin plus IVIG should be recommended as the first-line therapy in the initial treatment of Kawasaki disease.

BACKGROUND AND AIMS: Helicobacter pylori (HP) culture for diagnosing HP infection is time-consuming and technologically complex. This study evaluated the clinical significance of gastric mucosal gene chip technology in the rapid diagnosis of HP infection and detection of drug resistance in children. METHODS: Patients (between the age of 2.5 and 16.0 years old) manifesting gastrointestinal symptoms were enrolled in this study. HP culture of gastric mucosa and drug sensitivity test were performed. A gene chip of gastric mucosa was used to detect the presence of HP infection, some single nucleotide polymorphisms in HP drug resistance genes, or associated gene mutation. DNA sequencing was investigated and compared with the gene chip test results. RESULTS: Out of 267 cases, HP culture was positive in 169 cases and negative in 98 cases. HP detection by the gene chip method was positive in 208 cases and negative in 59 cases. The sensitivity, specificity, and accuracy of the gene chip technology for diagnosing HP infection were 96.1, 85.0, and 93.6%, respectively. HP resistance gene locus using the gene chip showed the main mutation locus of clarithromycin to be 2143A/G, levofloxacin at locus GyrA 91 and GyrA 87, and amoxicillin at PBP1 556ser. Concordance rates between gene chip and DNA sequencing for VacA-S/M, 16S rRNA, 23S rRNA, and GyrA were greater than 95%, and that of PBP1 was greater than 82%. CONCLUSION: Gastric mucosal gene chip technology can be used for rapid diagnosis and drug resistance detection of HP infection in children.
