Acyclovir-resistant varicella zoster virus infection may complicate long-term oral acyclovir administration in patients with AIDS and may be associated with the appearance of atypical hyperkeratotic papules. Human alphaherpesvirus 3 (HHV-3), usually referred to as the varicella- zoster virus (VZV), is one of eight herpesviruses known to infect humans. It causes chickenpox ( varicella), a disease most commonly affecting children, teens, and young adults, and shingles (herpes zoster) in adults Varicella-zoster virus (VZV) causes chickenpox and herpes zoster (shingles). Chickenpox follows initial exposure to the virus and is typically a relativelyCompartmentalization of acyclovir-resistant varicella zoster virus: implications for sampling in molecular diagnostics. Clin Infect Dis. Varicella-zoster virus (VZV) is a common herpesvirus responsible for disseminated or chronic infections in immunocompromised patients. Effective drugs such as acyclovir (ACV), famciclovir (prodrug of penciclovir), and foscarnet are available to treat these infections. Acyclovir-resistant HSV (ACV-R-HSV) infections were first described in 1982.1 To date, over 100 patients with ACV-R-HSV infection have beenPahwa S, Biron K, Lim W, Swenson P, Kaplan MH, Sadick N, Pahwa R. Continuous varicella-zoster infection associated with acyclovir resistance in a Varicella zoster virus, resistant to acyclovir in vitro, was isolated from skin lesions of all four patients. Three patients were adults in whom the acquired immunodeficiency syndrome (AIDS) had been diagnosed 12 to 20 months before isolation of acyclovir-resistant varicella zoster virus. Varicella-zoster virus (VZV), a neurotropic herpesvirus, is the causative agent of both varicella (chickenpox) and zoster (shingles).resistance.

Varicella-zoster virus (VZV) resistance to acyclovir (ACV) has only been reported in rare cases of immunocompromised patients.

It must be given by IV, usually three times a day, often in a hospital or under close supervision of an in-home nurse.

J Infect Dis. Varicella-zoster virus (VZV) is a double-stranded DNA virus that belongs to the Alpha-herpesvirinae subfamily of the Herpesviridae family ofAlternative antiviral agents for varicella include valacyclovir, the L-valine ester of acyclovir that is converted to acyclovir after oral administration, and famciclovir. CHARACTERISTICS: Varicella-Zoster virus belongs to the subfamily alphaherpesviridae in the Herpesviridae family, genus Varicellovirus.DRUG SUSCEPTIBILITY: Acyclovir has been shown to inhibit viral replication. Some strains resistant to acyclovir have been reported, mainly in HIV Varicella zoster immune globulin (VariZIG) is recommended for those who cannot receive the vaccine, usually due to immunosuppression, are susceptible and at risk ofSafrin, S, Berger, TG, Gilson, I. “Foscarnet therapy in five patients with AIDS and acyclovir-resistant varicella-zoster virus infection”.
