Herpes zoster is caused by reactivation of varicella zoster virus (VZV) from the dorsal sensory ganglia or the cranial nerve ganglia after a previous primary infection with chickenpox. It is known that pediatric zoster rarely occurs and usually not so severe when it develops, except in immunocompromised children 1) . In particular, herpes zoster in infancy is very rare but can be developed foll...
OBJECTIVE To assess longitudinally the antiviral immune response of T cells from patients with multiple sclerosis (MS) treated with fingolimod (FTY) vs other disease-modifying treatments (DMTs). METHODS We assessed cellular immune responses specific to influenza virus (FLU), JC virus (JCV), and varicella-zoster virus (VZV) using quantification of interferon-γ secretion by enzyme-linked immuno...
Recurrent varicella infection is rare but has been reported in immunocompromised patients. We present a patient with atypical recurrent varicella infection who had disseminated central crusting papular lesions without dermatomal distribution. Serology showed previous varicella zoster virus (VZV) infection and the lesions were positive for VZV DNA, consistent with recurrent VZV infection. Atypic...
Varicella-zoster virus (VZV) is responsible for primary infections as well as reactivations after latency in the dorsal root ganglia. The treatment of such infections is mandatory for immunocompromised patients and highly recommended for elderly patients with herpes zoster infections (also called zona or shingles). The treatment of choice is presently based on four molecules, acyclovir (ACV), v...
BACKGROUND The labile nature of live, attenuated varicella-zoster virus (Oka/Merck) requires robust stabilization during virus bulk preparation and vaccine manufacturing in order to preserve potency through storage and administration. One stabilizing ingredient used in a varicella-zoster virus (VZV) vaccine is hydrolyzed porcine gelatin which represents the major protein/peptide-based excipient...
We report the first laboratory-documented case of herpes zoster caused by the attenuated varicella zoster virus (VZV) contained in Zostavax in a 68-year-old immunocompetent adult with strong evidence of prior wild-type VZV infection. The complete genome sequence of the isolate revealed that the strain carried 15 of 42 (36%) recognized varicella vaccine-associated single-nucleotide polymorphisms...
Zoster sine herpete is a particular form of varicella zoster virus (VZV) infection characterized by segmental pain and dysesthesia, without any cutaneous lesions ever becoming perceptible. This report describes the case of a female patient, presenting with intercostal pain associated with a single papulo-vesicular lesion localized within the same area. Thanks to such a lesion, real time-polymer...
Herpes zoster occurs in 10% to 20% of the general population as a result of reactivation of the varicella-zoster virus (VZV) and is generally benign. It occurs more frequently in persons with cellular immunodeficiency and older age. The association between herpes zoster and HIV was confirmed early in the course of the HIV epidemic by numerous studies. Zoster was noted to precede AIDS in high-ri...
BACKGROUND The Depression Substudy of the Shingles Prevention Study (SPS) was designed to evaluate the association between major depression and immune responses to a high-titer live attenuated varicella zoster virus (VZV) vaccine (zoster vaccine), which boosts cell-mediated immunity (CMI) to VZV and decreases the incidence and severity of herpes zoster (HZ). The Depression Substudy was a 2-year...
