| Popis: | Background: With the identification of blood donors with a subsequent positive result in HCV screening and the possibility of HCV transmission via their previous negative donations, the role of look-back investigation has been crucial in enhancing blood safety. A retrospective study was conducted to identify the fate of blood components from donors subsequently found to be confirmed HCV positive cases with previous negative donations. Objectives: This look-back study aimed to determine the transfusion-induced hepatitis C virus infection through previous HCV-negative donations of subsequent HCV positive blood donors in Iran. Methods: In this study, all serologically confirmed HCV positive blood donors across the country from December 2015 to June 2017 were included. A look-back process was conducted by tracing back previous HCV negative donations of subsequent HCV-positive blood donors to specific recipients, according to the IBTO instructions. The HCV RNA testing was carried out using an in-house one-step TaqMan real-time RT-PCR assay. Results: During the study period, 280 serologically confirmed HCV-positive blood donors were included, with 267 as first-time, nine as repeated, and three as regular donors. Of the participants, the first-time donors were excluded, the repeated donors were not eligible, and only the regular donors were selected for the look-back study. The HCV RNA was detected in one regular donor, but HCV infection was not detected in his previous donation recipient. In addition, more than two HCV risk factors were reported by each regular blood donor. Conclusions: According to the results, evidence of HCV transmission via previous blood transfusions and the risk of HCV infection was not observed among recipients. Due to the reporting of some HCV risk factors by the subjects, paying proper attention to the donor selection process is highly recommended. |
