[Prevalence and incidence of cytomegalovirus infection in patients infected with HIV-1. SEROCO group]. / Prévalence et incidence de l'infection par le cytomégalovirus chez les sujets infectés par le VIH-1. Le groupe SEROCO.

ABSTRACT

OBJECTIVES: To study prevalence of the cytomegalovirus (CMV) infection as well as incidence of the CMV seroconversions in HIV-infected subjects enrolled in the French multicentric cohort SEROCO. METHOD: Prevalence of CMV infection at inclusion in the cohort was estimated from 1504 HIV-infected subjects. Incidence of the CMV seroconversion was estimated from 184 subjects CMV seronegative at inclusion. Cox model was used to identify independent factors related to CMV seroconversion. RESULTS: CMV prevalence was high (87.2%) mainly in homosexual men. The incidence of the CMV seroconversions was also high (9, 18/100 person-years), particularly in homosexual men, in subjects declaring sexual intercourse with occasional partner, and in those declaring a sexually transmitted disease during the follow-up. CONCLUSION: The risk to develop serious disease related to CMV in subjects with AIDS being particularly high when the CMV primary infection occurs during the course of the HIV infection, the prevention of CMV primary infections is thus a major element in the counselling of HIV-infected subjects.
