The antiherpetic drugs acyclovir (ACV, valaciclovir) and penciclovir (famciclovir) are phosphorylated by viral thymidine kinase and terminate DNA synthesis. ASP2151 (amenamevir) and foscavir (PFA) directly inhibit viral helicase-primase and DNA polymerase, respectively, and inhibit replication of herpes simplex virus (HSV) and varicella-zoster virus. ACV, ASP2151, and PFA all inhibit HSV with a different mechanism of action and as a consequence, the kinetics of viral DNA accumulation and progeny virus production differ...

Acute retinal necrosis syndrome (ARNS) is a rare but devastating uveitic syndrome with devastating visual outcome (visual prognosis ++). It should be diagnosed as early as possible because of its severity and its risk of bilateralization. This is a rare entity caused by the group of herpes viruses. In immunocompromised patients the complications of RNA syndrome often lead to loss of visual acuity. After the discovery of this disease using polymerase chain reaction (PCR) and immune load coefficient (ILC) usually by puncturing the cornea to evacuate the aqueous humour, the confirmation of this diagnosis allows for faster optimization of disease management decreasing the time required to confirm the diagnosis...

BACKGROUND: The epidemiology of cutaneous herpes simplex infection (CHSI) has dramatically changed over the past several decades. Valaciclovir is one of a new generation of antiviral medications that has expanded treatment options for the most common cutaneous manifestations of herpes simplex virus. However, the efficacy and safety of formulations with different doses of valaciclovir remain unclear. AIM: To carry out hospital risk management by ascertaining the incidence and risk of CHSI in patients during treatment with varying doses of valaciclovir...

An 81-year-old woman suffering from sarcoidosis, chronic renal failure caused by hypertention was treated by valacyclovir 500 mg/day, for the diagnosis of herpes zoster of her right back. Her consciousness gradually became worse, and 3 days after taking the drug, she was sent to the emergency department of the hospital. Her conscious level was E2V2M5 (Glasgow Coma Scale) and myoclonus especially in her lower extremities occurred. Head CT and MRI show no obvious, acute abnormal findings other than chronic ischemic lesions, while an electroencephalogram (EEG) shows periodic synchronous discharges (PSDs) and disorganized background activity...

Recurrent erythema multiforme (EM) is rare and is most typically related to infections with herpes simplex virus. Prophylactic administration of valaciclovir is the first-line treatment, but there is no agreement about second-line treatment in cases of ineffectiveness. We present a 31-year-old man who was not infected with hepatitis C virus (HCV), and had a history of severe and recurrent EM, unresponsive to valaciclovir, colchicine and hydroxychloroquine. The patient noticed that an intermittent flu-like illness seemed to have abrogated an EM flare...

Herpes zoster (HZ) is a common disease characterized by the recurrence of varicella zoster, that stays dormant in sensory ganglia. The primary goal of this study was to compare efficiencies of famciclovir, valaciclovir, and brivudine in terms of pain relief in HZ patients. Records of patients who were admitted to the Dermatology Clinic of our hospital due to acute HZ between the years 2012 and 2014 were retrospectively analyzed. Treatment decisions were at the discretion of caring physicians as valaciclovir (VACV), famciclovir (FCV), and brivudine (BRV) based on the clinical observations...

A 36-year-old man presented with facial nerve palsy, hearing loss, vertigo and headache. He was initially diagnosed with Ramsay Hunt syndrome and treated with a systemic steroid and valaciclovir; however, his symptoms deteriorated. Serum rapid plasma reagin (RPR) and treponema pallidum hemagglutination tests were positive. Cerebrospinal fluid analysis revealed an elevated white blood cell count and positive RPR, confirming the diagnosis of neurosyphilis. Penicillin G (PCG) was administered, and his facial nerve function and headache improved...

Herpes simplex virus type 1(HSV-1) remains latent in the human trigeminal ganglion after primarily infecting the cornea and conjunctiva. Mental stress, heat stimulation, ultraviolet ray and immunosuppression are among the reactivating factors of HSV-1, which can lead to epithelial herpetic keratitis, stromal herpetic keratitis, and other complications. I have been working with HSV-1 for a long time, concentrating especially on its latency and reactivation. I would like to introduce some of the recent research results...

The current guidelines for the treatment of primary herpes simplex in the Genito-urinary department in Sheffield Teaching Hospitals NHS Foundation Trust, recommend valaciclovir as a first-line medication. This is a prodrug of aciclovir, which has been used for many years as a treatment for primary herpes simplex virus. The basis of the recommendation largely relates to valaciclovir being more bioavailable than aciclovir. However, there is no evidence to suggest this has an effect on overall outcome with regard to symptom control and viral shedding...
