Transmission of HCV during dialysis. Convincing data are available that demonstrate an increased risk of anti-HCV seroconversion associated with both a failure to strictly follow infection control procedures and the performance of dialysis at a station immediately adjacent to that of a patient testing positive for anti-HCV [71-75]. Units using dedicated machines have shown a decreased incidence of seroconversion [51]. The literature provides conflicting data on the likelihood of passage of HCV RNA into dialysis ultrafiltrate and the risk of contamination by reprocessing filters [71,72,76-78]. At this time the Centers for Disease Control does not recommend that patients who are HCV positive be isolated or dialyzed on dedicated machines and has no official policy concerning reuse of machines in these patients [79].
