Management of resistant mucocutaneous herpes simplex infections in AIDS patients: a clinical and virological challenge.
BACKGROUND
The use of highly active antiretroviral therapy (HAART) has been associated with a marked decrease in the prevalence of opportunistic infections in HIV-infected patients. However, chronic mucocutaneous herpes simplex virus (HSV) infection remains a difficult clinical challenge.


OBJECTIVE
The aim of the study was to optimize the diagnosis and follow-up of chronic HSV-2 infection in HIV-infected patients and to correlate clinical data with CD4 cell count, in vitro HSV virological resistance and histology.


METHODS
A retrospective case series was collected from a specialist out-patient clinic providing consultations to patients with infectious skin diseases. Clinical, biological, virological and histological data were analysed.


RESULTS
Seven HIV-infected patients with genital and perianal herpes simplex infection were followed over 10 years. Ulcerative and pseudo-tumoral forms were observed. Lesions occurred at various stages of immune suppression (CD4 counts from 1 to 449 cells/μL). Clinical resistance to conventional anti-herpetic drugs was correlated with the in vitro resistance of HSV in 70% of cases.


CONCLUSIONS
Chronic mucocutaneous HSV infection in AIDS patients remains a rare but regularly observed infection in very immunosuppressed patients or those with unstable immunity during HAART. Virological results obtained from mucocutaneous samples were in most cases found to be correlated with clinical evolution and should therefore be used in making decisions on treatment. Despite efficient antiviral therapy, mucocutaneous healing is slow in the majority of cases.
