Ganciclovir-resistant cytomegalovirus infection in renal transplantation
Cytomegalovirus (CMV) infection is an important cause of morbidity in renal transplant recipients, due to both direct and indirect effects of the virus on the graft and patient [1]. Ganciclovir (GCV) remains the most common first-line therapy, but its low oral bioavailability was identified as a risk factor for the emergence of resistant strains [1], and intravenous (IV) administration is incon...
متن کاملSusceptibilities of human cytomegalovirus clinical isolates to BAY38-4766, BAY43-9695, and ganciclovir.
BAY38-4766 and BAY43-9695 are nonnucleosidic compounds with activities against human cytomegalovirus (HCMV). Two phenotypic assays were used to determine the drug susceptibilities of 36 HCMV clinical isolates to the BAY compounds and ganciclovir. Using either assay, both BAY compounds at a concentration of approximately 1 microM inhibited the replication of all 36 HCMV clinical isolates, includ...
متن کاملGanciclovir Resistant Cytomegalovirus in Solid Organ Transplant Recipients: An Update
Ganciclovir-resistant cytomegalovirus (CMV) infection is an emerging problem in solid organ transplant (SOT) recipients. Treatments such as foscarnet and cidofovir are fraught with serious side effects that may limit their use in this condition. The aim of this paper is to elucidate the mechanisms on how resistance occurs, when to suspect it clinically and what special tests are necessary to di...
متن کاملNovel mutation in the UL97 gene of a clinical cytomegalovirus strain conferring resistance to ganciclovir.
Characterization of a ganciclovir-resistant cytomegalovirus strain from a patient with AIDS showed a histidine-to-glutamine change at residue 520 of UL97 (Q520 mutation). In anabolism studies, Q520 was associated with impaired phosphorylation of ganciclovir. Transfer of Q520 to a recombinant virus resulted in a ganciclovir-resistant phenotype.
متن کاملFlow cytometric determination of ganciclovir susceptibilities of human cytomegalovirus clinical isolates.
A flow cytometric assay has been developed for the measurement of susceptibilities to ganciclovir of laboratory strains and clinical isolates of human cytomegalovirus (HCMV). The assay uses fluorochrome-labeled monoclonal antibodies to HCMV immediate-early and late antigens to identify HCMV-infected cells and flow cytometry to detect and quantitate the number of antigen-positive cells. By this ...
