In this study we investigated the rate of HBV-DNA positivity in anti-HBc only-positive 45 patients (29 male, 16 female; mean age: 39.2 +/- 12.3 years) who were followed in the outpatient clinics of a University Hospital in Duzce (located at northern west part of Turkey). HBV markers were investigated by 3rd generation ELISA (MEIA Axsym-Abbott), and HBV-DNA were searched by real-time PCR [extraction: Minielute (Qiagen, Germany); PCR kits: Florion HBV (Iontek, Turkey); detection: i-cycler IQ5 (BioRad, USA)] methods. As a result, 24.4% (11/45) of the patients were found HBV-DNA Positive (> 10(3) copies/ml). There was no statistically significant difference of HBV-DNA positivity rates between males (9/29; 31%) and females (2116; 12.5%), (p = 0.15). It was concluded that there may be a serious risk of HBV transmission from anti-HBc only-positive patients since the rate of HBV-DNA positivity was found high in our study. Thus HBV-DNA screening should be performed in 'anti-HBc only' patient groups.trinfo:eu-repo/semantics/closedAccessLetter423535536WOS:000258416900022Q4
