[Reactivation of parvovirus B19 infection in an HIV-infected woman]. / Réactivation d'une infection à parvovirus B19 chez une patiente infectée par le VIH.

INTRODUCTION: Infection by human parvovirus B19 (erythrovirus B19) is common and usually asymptomatic during childhood conferring lasting protection against a new infection. Parvovirus B19 infection may cause erythema infectiosum (5th disease) and aplastic crisis. Secondary symptomatic parvovirus B19 infection in the same patient is rare and its physiopathology is not always clear. CASE REPORT: A 48-year-old HIV-infected female patient presented within 5 years two acute episodes of parvovirus B19 infection although her CD4 cells count was above 500/mm(3). Absence of specific antibodies production after the first episode and persisting parvovirus viremia suggested viral reactivation rather than re-infection. During the second episode, specific antibodies were produced. CONCLUSION: Similarly to most DNA viruses, parvovirus B19 reactivation is possible in HIV-infected patients while effectively treated by antiretroviral therapy.

Etravirine concentrations in the cervicovaginal compartment in HIV-1-infected women receiving etravirine-containing antiretroviral therapy: DIVA 02 study.

We studied the penetration of etravirine and HIV shedding in the genital tract among 12 HIV-1-infected women receiving an etravirine-containing regimen who had <40 copies/ml blood plasma (BP) HIV RNA. None of the cervicovaginal fluid (CVF) samples showed detectable HIV RNA. Median etravirine concentrations were 663 ng/ml in BP and 857 ng/ml in CVF, with a CVF/BP etravirine ratio of approximately 1.2. This good penetration of etravirine may contribute to the control of viral replication in the female genital tract.
