Current management of cytomegalovirus disease.
Cytomegalovirus (CMV) is an important pathogen for the fetus, for allograft recipients, and for acquired immunodeficiency syndrome (AIDS) patients; the clinical features in each of these groups of patients are described. CMV may also act as a cofactor to accelerate the rate at which the human immunodeficiency virus (HIV) causes AIDS. Active CMV infection in immunocompromised patients is best managed by routine laboratory screening of patients at risk using assays that provide prognostic information. Antiviral therapy can then be considered under one of four headings: For prophylaxis, the drug is given to all patients from a particular time point, e.g., time of transplantation. Successful trials have been reported for interferon (renal transplant), acyclovir (renal transplant and bone marrow transplant), and ganciclovir (heart transplant and bone marrow transplant). For suppression, the drug is given once CMV excretion has been detected in peripheral sites of particular patients. A successful trial of ganciclovir in bone marrow transplant patients has been reported. For pre-emptive therapy, the drug is given once CMV has been detected systemically. A successful trial of ganciclovir in bone marrow transplant patients has been reported. Regarding treatment, a controlled comparison of ganciclovir and foscarnet for CMV retinitis in AIDS patients has shown that both drugs are equally effective but that foscarnet has a survival benefit. Open studies suggest that the combination of immunoglobulin and ganciclovir is of benefit for treatment of established CMV pneumonitis. In open studies other treatments have been tried, with no clinical success, despite control of viral replication in some cases.(ABSTRACT TRUNCATED AT 250 WORDS)
