- W2470316191 abstract "Introduction: There are no current estimates of the risk of transmission of HIV, HBV, HCV, or HTLV by musculoskeletal tissue transplantation. Such accurate data would be helpful to determine the effectiveness of current and proposed screening and processing procedures, and contribute to increased confidence in the use of musculoskeletal tissue products. Methods: The prevalence rates of HIV, HBV, HCV, and HTLV were determined from 12.245 musculoskeletal tissue donors from three bone tissue banks across Australia from the period 1993 to 2004. The incidence rates among tissue donors were estimated by comparing the data with age-specific incidence rates of first-time blood donors. We estimated the probability of a tissue donor was within the window period when infection was undetected by serological screening procedures by the modified incidence-window period model. Further we calculated the projected probability of viremia with the addition of nucleic-acid amplification testing (NAT). Results: The prevalence (per 100,000 persons) of confirmed positive tests among musculoskeletal tissue donors was 169.15 for HIV, 427.68 for HBV, 534.63 for HCV, and 121.66 for HTLV. This is greater than the prevalence among first-time blood donors during the same period (6.47 for HIV, 136.00 for HBV, 215.29 for HCV, and 3.46 for HTLV). The incidence rate among musculoskeletal donors were estimated to be 15.81, 0.68, 3.53, and 4.85 per 100,000 person-years, respectively. The estimated probability of viremia (per 100,000 persons) at the time of donation was 1.38 for HIV, 0.46 for HBV, 1.82 for HCV, and 0.85 for HTLV. These estimations would be even lower with the addition of NAT – 0.57, 0.23, and 0.20 respectively. Conclusions: The prevalence and incidence of HIV, HBV, HCV, and HTLV among musculoskeletal tissue donors, although low are significantly higher than those of first-time blood donors. Current screening and processing measures are effective, though the probability of viremia can be reduced further by nucleic-acid amplification testing." @default.
