Abstract

The development of antiviral-resistant cytomegalovirus (CMV) infection complicates the management of transplant recipients. We describe the case of a 65-year-old male who developed CMV disease on valganciclovir prophylaxis (donor CMV IgG positive, recipient CMV IgG indeterminate) 30 days after combined liver-kidney transplantation for alcoholic cirrhosis and hepato-renal syndrome. After an initial complete response to treatment dose oral valganciclovir, he developed recurrent CMV viraemia. Resistance testing revealed a UL97 mutation with in-frame deletions of codons 595-596. He was treated successfully with foscarnet and reduction in immunosuppression. This mutation has not been described pr..
