Typical cytomegalovirus retinitis in non-human immunodeficiency virus partially immunosuppressed patients: A case series

The purpose of the study was to analyze the occurrence of severe, typical cytomegalovirus (CMV) retinitis (CMVR) in human immunodeficiency virus (HIV) negative, partially immunosuppressed patients, emphasizing inconsistency in the clinical presentation of CMVR and to evaluate the role of combined anti-CMV therapy in the management of such patients. This study was a retrospective, observational, noncomparative case series. We examined and treated consecutive HIV-negative adult patients of CMVR. Blood-based polymerase chain reaction analysis of the CMV genome was done pre- and posttreatment. Details of underlying systemic conditions were collected. Patients were treated with simultaneous administration of intravitreal and intravenous (IV) anti-CMV therapy. Follow-up was for 1 year. All outcomes were determined retrospectively. A total of 6 eyes of 4 consecutive patients were diagnosed with CMVR in HIV-negative patients. Patients were only partially immunosuppressed but revealed typical severe fulminant CMVR. Patients received a total of 2 intravitreal ganciclovir injections, and IV ganciclovir/oral valganciclovir was given. All patients achieved complete healing within the treatment period. As opposed to the general perception, typical, fulminant, severe CMVR may occur in patients with limited immune dysfunction. Our report underlines this inconsistency in the clinical presentation of CMVR in partially immunosuppressed patients. The immune status of the patients seems a significant factor in determining the clinical phenotypes of CMVR. Combined intravitreal and IV ganciclovir/oral valganciclovir therapy was successful in treating this group of CMVR patients.
