The prevalence of serum HBsAg and Anti-HBs was studied in 201 staff members from two Renal Dialysis Units, one Medical and one Dermatological Division from two Hospitals in the Milano area. The overall prevalence of HBsAg was significantly greater among staff members (8.9%) as compared to controls (4.9%). On the contrary, the prevalence of Anti-HBs was only slightly higher in hospital personnel than in controls. Non-medical staff members (nurses, technicians) showed a prevalence of HBV markers (HBsAg and/or Anti-HBs) twice as high as medical staff members (46.1% vs 23.2%). When the prevalence of HBV markers was correlated to the duration of work in the hospital, a steady increase in the prevalence of Anti-HBs was observed. On the contrary, the prevalence of HBsAg rose in the first 3 years and remained constant thereafter. The prevalence of HBV markers was significantly higher among staff members from Renal Dialysis Units (HBsAg+ and/or Anti-HBs+:50%) than in the personnel from the Medical and Dermatological Divisions (32.4%). However, the difference was solely related to a higher prevalence of Anti-HBs in the former (42% vs 23%). This may reflect a higher risk of infection in Dialysis Units as compared to other Hospital Divisions. However, the difference might be magnified by the frequent use of HBIG in the Dialysis Units personnel.
