Valacyclovir and famciclovir enabled successful systemic therapy for treating herpes simplex virus (HSV) and varicella zoster virus (VZV) infection by their phosphorylation with viral thymidine kinase. Helicase-primase inhibitors (HPIs) inhibit the progression of the replication fork, an initial step in DNA synthesis to separate the double strand into two single strands. The HPIs amenamevir and pritelivir have a novel mechanism of action, once-daily administration with nonrenal excretory characteristics, and clinical efficacy for genital herpes...

Actin filaments, microtubules and intermediate filaments form the cytoskeleton of vertebrate cells. Involved in maintaining cell integrity and structure, facilitating cargo and vesicle transport, remodelling surface structures and motility, the cytoskeleton is necessary for the successful life of a cell. Because of the broad range of functions these filaments are involved in, they are common targets for viral pathogens, including the alphaherpesviruses. Human-tropic alphaherpesviruses are prevalent pathogens carried by more than half of the world's population; comprising herpes simplex virus (types 1 and 2) and varicella-zoster virus, these viruses are characterised by their ability to establish latency in sensory neurons...

Herpes zoster, or shingles, is caused by reactivation of varicella zoster virus, which causes chickenpox. There are an estimated 1 million cases in the Unites States annually, with an individual lifetime risk of 30%. Patients with conditions that decrease cell-mediated immunity are 20 to 100 times more likely to develop herpes zoster. Patients may present with malaise, headache, low-grade fever, and abnormal skin sensations for two to three days before the classic maculopapular rash appears. The rash is usually unilateral, confined to a single dermatome, and typically progresses to clear vesicles that become cloudy and crust over in seven to 10 days...

Objectives Herpes zoster (HZ) mainly affects elderly people and immunocompromised individuals. HZ is usually characterized by a unilateral painful skin rash. Its most common complication, postherpetic neuralgia (PHN), may cause chronic debilitating pain. This study aimed to estimate the HZ incidence in individuals aged ≥50 years in Germany, the proportion of PHN and the economic burden. Methods From 2010 to 2014, HZ-patients were recruited when consulting physicians in physician networks covering about 157,000 persons aged ≥50 years...

OBJECTIVE: Herpes zoster (HZ) can develop into postherpetic neuralgia (PHN), which is a chronic neuropathic pain (NP). Whether the chronification from HZ to PHN induced brain functional or structural change is unknown and no study compared the changes of the same brains of patients who transited from HZ to PHN. We minimized individual differences and observed whether the chronification of HZ to PHN induces functional and pain duration dependent grey matter volume (GMV) change in HZ-PHN patients...

We studied the relationship between varicella-zoster virus (VZV) DNAemia and development of VZV-specific immunity after administration of live-attenuated zoster vaccine. VZV-DNAemia, detected by polymerase chain reaction (PCR), and VZV-specific effector (Teff) and memory (Tmem) T cells, was measured in 67 vaccinees. PCR was positive in 56% (9 direct, 28 nested) on day 1 and in 16% (1 direct, 10 nested) on day 14. Teff progressively increased in direct-PCR-positive vaccinees up to day 30, but Tmem did not. Conversely, Tmem, but not Teff, increased in direct-PCR-negative vaccinees on day 7...

Segmental zoster paresis is an uncommon complication of herpes zoster, and abdominal wall pseudohernia is rare. Previous reports have emphasized the involvement of anterior rami of spinal nerves, while the involvement of posterior rami has been less frequently reported. We aimed to elucidate the involvement of posterior rami of spinal nerves in abdominal wall pseudohernia. Four patients with a diagnosis of abdominal wall pseudohernia underwent needle electromyography (nEMG) and magnetic resonance imaging (MRI)...
