ABSTRACT
Kawasaki disease (KD) is the most common cause of pediatric acquired heart disease. KD patients have spontaneously high plasma/serum levels of IL-10 during the acute phase. Therefore, two independent studies were carried out to investigate the association between genetic variants in IL-10 promoter (-1082, -819, and -592) and risk of KD. A total of 134 trios were included for the family-based association study. A significantly preferential transmission of the C allele at loci -819 T > C and -592 A > C for KD cases was observed (P permutation = 0.029 and P permutation = 0.034, respectively). There was a significant increase in the transmission of haplotype CC (p = 0.016) at the above two loci (OR, 1.632; 95% CI, 1.090-2.443; P permutation = 0.019). We also carried out a follow-up case-control study that included 146 KD cases and 315 unrelated healthy children. The haplotype CC (-819, -592) showed an increased risk of KD (but statistically non-significant; OR, 1.332; 95% CI, 0.987-1.797; p = 0.061). In diplotype analysis, a trend was found between number of CC haplotype and risk of KD (but non-significant, p =0.061). In conclusion, CC genotype and CC/CC diplotype at IL-10-819T > C and -592A > C were significantly associated with risk of KD in case-parent trio study, which were replicated partially in our follow-up case-control study.

Infectious gastroenteritis is a common illness in children. This study investigated the etiology and clinical manifestations of hospitalized children with symptoms of infectious gastroenteritis in southern Taiwan. We studied 467 consecutive patients with infectious gastroenteritis aged from 2 days to 10 years hospitalized from April 2001 to March 2002. Rotavirus was the most common etiology (57%) of infectious gastroenteritis in these patients. Bacterial infection was noted in 57 cases (12%). Rotavirus was found in 92% of nosocomial infectious gastroenteritis (p < or = 0.001). Bloody stool was a presentation of bacterial infection in 74% of cases and rotavirus gastroenteritis in 8% of cases (p < or = 0.001). The G serotype of rotavirus was identified in 87 patients. Serotype G1 was the most common (51%), followed by G9 (31%). The emergence of serotype G9 strains in rotavirus infection has not been previously reported from Taiwan. Incorporation of G9 rotavirus into vaccines should be considered.
