Background: Direct acting antiviral therapies (DAA) are an important tool for hepatitis C virus elimination.  Cross-contamination as a result of failure to follow infection control procedures.  We estimated HCV reinfection rates among treated individuals on maintenance hemodialysis (MHD) in our dialysis patients.

Methods: We analyzed data from Jinnah hospital dialysis center cohort on maintenance hemodialysis who previously took direct acting antiviral therapy (DAA) for treatment of hepatitis C in a prospective randomized interventional trial which included 36 patients.  These patients were followed for one year after sustained virologic response (SVR) was achieved.  At one year, reinfection was defined as a positive HCV RNA measurement at one year after achievement of SVR. Genotype was also assessed for patients who had positive HCV RNA by PCR.  As a secondary objective, one year mortality was also calculated in this treated population.

Results: Of 32 patients who were treated with DAAs, SVR after one year of completion of treatment was 100% in group 1 and 85.8% in group 2.  None of the patients in group 1 had reinfection one year after achieving SVR while 2 out of 14 patients in group 2 were found to have reinfection with same genotype as previous. Overall reinfection rate was 2/32 (6.25%). Crude reinfection rate per 100 person-years was 6.25. One year mortality was 16% and 44% in group 1 and 2 respectively.

Conclusion: Reinfection rate is low among successfully treated HCV patients on maintenance hemodialysis when strict implementation and adherence to ‘universal precautions’ is practiced.
