[Detection of DNA human cytomegalovirus of a molecular methods: hybrid capture DNA CMV by immunocompromised]. / Detection de l'adn du cytomegalovirus humain par hybridation moleculaire chez les immunodéprimés.

ABSTRACT

Human cytomegalovirus (HCMV), a member of the beta-virus herpes family, is a ubiquitous human pathogen. After a primary infection, HCMV establishes life latency. HCMV rarely causes symptomatic disease in an immunocompetent host, however, it is a major cause of infectious morbidity and mortality in immunocompromised individuals and developing fetuses. The HCMV genome consists of 240 kbp of double stranded DNA. Early diagnosis molecular of CMV infection is important. The objective of this study was to develop a molecular methods: Quantitative Hybrid capture for the detection of DNA CMV. We present results for 200 immunocompromised collected from 1999 to 2003 (122 men and 78 women, whom mean age was 35 years). Our results showed that 25% of women and 36% of men were positif for hybrid capture DNA CMV. This simple test (cold probe) provide quantitative and fast results. Also the efficacity of anti-CMV therapy can be followed. More over, in contrary with pp65-antigenemia assay and CMV PCR, this test can be managed on biopsy sample.
