Abstract

The genetic susceptibility to and vaccine effectiveness against rotavirus gastroenteritis were different in distinct ethnic groups. The case-control study was aimed to evaluate the effectiveness of rotavirus vaccines and associations between the histo-blood group antigens and susceptibility to rotavirus infections in a Taiwanese population. Cases were children <18 years old who were hospitalized because of laboratory-confirmed rotavirus infection. Controls were healthy children matched to cases by age and gender. The secretor status and Lewis antigen and ABO types were determined by molecular methods. A total of 68 cases and 133 controls were included. Rotavirus immunization was recorded in 8 (12%) cases and 77 (58%) controls, indicating a vaccine effectiveness of 90.3% (95% confidence interval [CI], 78.1% - 95.7%). The secretor and Lewis-positive genotypes were independently associated with increased risk of rotavirus infections (matched odds ratio [mOR] 28.5, 95% CI 2.94-277, P = 0.003 and mOR 16.8, 95% CI 1.08-2601, P = 0.04, respectively). The distribution of ABO blood types did not differ significantly between cases and controls (P = 0.47). In conclusion, Taiwanese children with the secretor genotype and Lewis-positive genotype were at increased risk of moderate-to-severe rotavirus infections. The illness can be effectively prevented by immunization in this population.
