Abstract
Summary: A prospective study of hepatitis that began in 1968 and continues to include more than half the dialysis units in the United Kingdom shows that type B infection has been completely controlled in such units since the last outbreak ended in 1973. Though occasionally a single patient has developed hepatitis B surface antigenaemia in the course of dialysis or after transplantation, the infection has not spread to other patients or staff in the survey units.A detailed analysis of the results in 1974–75 shows clustering of patients with raised aminotransferase levels in about one-fifth of the units but, unlike past outbreaks of hepatitis B, these clusters are not accompanied by clinical hepatitis among staff. The possibility that some of the clusters are caused by hepatitis viruses other than type A or B is discussed. It is concluded that, when reliable tests for type non-A non-B infections become available, the continued existence of the survey will allow prompt assessment of any viral hepatitis problems that may still exist in UK units.
