Abstract

- We determined A/H1N1-hemagglutinin (HA) antibodies in relation to HLAD-Q genotypes and islet autoantibodies at clinical diagnosis in 1141 incident 0.7 to 18-year-old type 1 diabetes patients diagnosed April 2009-December 2010. Antibodies to S-35-methionine-labelled A/H1N1 hemagglutinin were determined in a radio-binding assay in patients diagnosed before (n = 325), during (n = 355) and after (n = 461) the October 2009-March 2010 Swedish A(H1N1) pdm09 vaccination campaign, along with HLA-DQ genotypes and autoantibodies against GAD, insulin, IA-2 and ZnT8 transporter. Before vaccination, 0.6% patients had A/H1N1-HA antibodies compared with 40% during and 27% after vaccination (P less than 0.0001). In children less than3 years of age, A/H1N1-HA antibodies were found only during vaccination. The frequency of A/H1N1-HA antibodies during vaccination decreased after vaccination among the 3 less than 6 (P = 0.006) and 13 less than 18 (P = 0.001), but not among the 6 less than 13-year-olds. HLA-DQ2/8 positive children less than3 years decreased from 54% (15/28) before and 68% (19/28) during, to 30% (9/30) after vaccination (P = 0.014). Regardless of age, DQ2/2; 2/X (n = 177) patients had lower frequency (P = 0.020) and levels (P = 0.042) of A/H1N1-HA antibodies compared with non-DQ2/2; 2/X (n = 964) patients. GADA frequency was 50% before, 60% during and 51% after vaccination (P = 0.009). ZnT8QA frequency increased from 30% before to 34% during and 41% after vaccination (P = 0.002). Our findings suggest that young (less than3 years) along with DQ2/2; 2/X patients were low responders to Pandemrix (R). As the proportion of DQ2/8 patients less than3 years of age decreased after vaccination and the frequencies of GADA and ZnT8QA were enhanced, it cannot be excluded that the vaccine affected clinical onset of type 1 diabetes.
