| Outline of Final Research Achievements |
This research determined the prevalence of HIV, HBV and Treponema pallidum (TP) in populations who visited primary sexually transmitted infection (STI) clinics in Osaka province. Compared with HIV-negative groups, the HBs antigen-positive rate and the seroprevalence of HBV among HIV positive-individuals were significantly higher (P<0.001). Genetic analysis revealed that 17 of 23 (74%) HBV isolates detected in HIV co-infected cases were the foreign genotypes of Ae and G, including three of Ae/G recombinant viruses. From these results, it is highly recommended for clinicians to consider HIV testing when a patient attending a primary STI clinic is positive for HBs antigen, especially in case it is a foreign genotype HBV. The rate of TP antibody positivity was not significantly different between HIV-positive and HIV-negative groups during 2006-2014.
