[Current developments in the diagnosis and therapy of cytomegalovirus infections].

We describe the case history of a 40-year-old, negroid woman with systemic lupus erythematosus who acquired a severe cytomegalovirus infection on immunosuppression; this infection was successfully treated with ganciclovir. New ideas in the management of CMV infections in immuno-compromised hosts are discussed. The traditional diagnostics are unsatisfactory, antibody detection being very insensitive and culture techniques too slow. A new diagnostic approach by detection of the immediate early antigens of the cytomegalovirus (CMV-IEA) using monoclonal antibodies is fast and reliable (sensitivity 93%, specificity 92%), even in case of immuno-deficiency. Finally we discuss the efficacy of the antiviral agent ganciclovir in the management of severe CMV infections.
