MedicalResearch.com Interview with: Dr Tsai Chung-Li Graduate Institute of Biostatistics, College of Management, China Medical University,Taichung, Taiwan and Dr. Hsiao-Chuan Lin Department of Public Health, College of Public Health, and Department of Pediatrics, China Medical University, Taichung, Taiwan Medical Research: What are the main findings of the study? Response: We conducted a nationwide population-based cohort study that included two groups. Children with enterovirus infection (aged < 18 years) during 2000-2007 were identified and followed up until December 31, 2008 or until first occurrence of type 1 diabetes. The group without enterovirus infection comprised half of all insured children of the same age and without a diagnosis of enterovirus infection. By use of frequency-matching with sex and birth year, children in the group with enterovirus were selected from those eligible. This nationwide retrospective cohort study found:
  • type 1 diabetes is positively correlated with enterovirus infection in patients younger than 18 years.
  • the incidence rate of type 1 diabetes was lower in the non-enterovirus than the¬†enterovirus group (4 vs 6 per 100,000 person-years; incidence rate ratio 1.48 [95% CI 1.19, 1.83]).
  • children that have been infected with enterovirus are 48% more likely to have developed type 1 diabetes.
  • the risk of developing type 1 diabetes is 2.18 times greater among children aged 10 years and older than among those aged younger than 1 year.

MedicalResearch.com: What are the main findings of the study? Answer: From this trial, the inactivated alum-adjuvant EV71 vaccine showed a good protection for both the EV71-associated HFMD and EV71-associated disease. The vaccine gave 90% protection against clinical EV71-associated HFMD and 80.4% against EV71-associated disease (including neurological complications) for at least 12 months. The safety profile and immunogenicity of this vaccine is proved to be clinical acceptable. We also proposed a titre (1:32) of neutralization antibody as surrogate of protection against EV71-associated disease.
