Herpes simplex-2 meningitis presenting with headache in pregnancy.

Herpes simplex virus (HSV) is a double-stranded DNA virus, whose primary target is epithelial cells. It is disseminated by hematogenous spread. HSV type 2 (HSV-2) usually causes genital infection with mucocutaneous lesions or it may be asymptomatic. HSV-2 is also an important cause of meningitis either during primary infection or by (recurrent) reactivation of dormant virus within the central nervous system. The authors present the case of a nulliparous woman in her mid-20s presenting to the emergency department at 22 weeks' gestation with acute onset of headache. CT of the head and magnetic r…

Fluorescent octahydrophenazines as novel inhibitors against herpes simplex viruses.

A new series of racemic fluorescent octahydrophenazines (rac-PZ1-11) have been designed and synthesized via the efficient nucleophilic aromatic substitution (SNAr) of tetrafluorobenzenedinitriles (1a-c) and racemic cyclohexane-1,2-diamines (rac-2a and b). The bioactivities of these racemic rac-PZs (20 μM) against herpes simplex virus type-1 (HSV-1) were evaluated by the relative cell viability of Vero cells infected with HSV-1. It was found that rac-PZ3 shows much higher anti-HSV-1 activity than others, with EC50 = 9.2 ± 1.4 μM. Further investigation into the anti-HSV activities of rac-PZ3 and…

Atypical Clinical Manifestations of Herpes Simplex Virus-1 Infection.

INTRODUCTION: The Herpes Simplex Virus-1 (HSV-1) infection of the oral cavity is a disease that initiates with prodromal symptoms such as fever and malaise, followed by the emergence of oral and perioral lesions. The common clinical manifestations of HSV-1 infection involve the development of vesicles on the face, oral mucosa and lips, which eventually progress to ulceration. This case report aims to present an atypical clinical manifestation of HSV-1 infection. HISTORY AND CLINICAL FINDINGS: A 62-year-old woman presented with complaints of a lump at the corner of her left lip, which had disa…

Transient Sinus Node Dysfunction Associated with Herpes Simplex Encephalitis.

Sinus arrest and inappropriate sinus bradycardia are sinus node dysfunction (SND), which cause loss of consciousness. Cardiac pacing is recommended in patients with symptoms, such as syncope or dizziness. Several conditions can induce these arrhythmias; however, whether or not intracranial infectious diseases, such as herpes simplex encephalitis (HSE), can cause secondary SND is unclear. We encountered a patient with sinus arrest and transient sinus bradycardia associated with HSE. Since cardiac pause was never monitored and the bradycardia improved after HSE treatment, HSE was suspected to be…

Small Animal Models to Study Herpes Simplex Virus Infections.

Herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) are two of the most prevalent human viruses worldwide. They are known to cause a variety of diseases including genital herpes, meningitis, encephalitis, cold sores and herpes stromal keratitis. The seropositive rate for HSV-1 is around 90%, whereas for HSV-2 it remains around 20-25% for the general adult population. The infections caused by these viruses remain difficult to study because a large proportion of infected individuals are asymptomatic. Furthermore, given the neurotropic characteristics of the virus, studies…

Когда герпес простейший вирус энцефалит соответствует антивирусному врожденному иммунитету.

Вирус герпеса (HSV) является наиболее распространенным патогеном инфекционного энцефалита, на который приходится почти половина подтвержденных случаев энцефалита. Его клинические симптомы часто нетипичны. ПЦР HSV в цереброспинной жидкости помогает диагностировать, и прогнозы, как правило, являются удовлетворительными после регулярной антивирусной терапии. Интересно, что некоторые пациенты, страдающие периодическим энцефалитом, имеют мало антивирусного эффекта. ПЦР HSV в цереброспинной жидкости отрицательный, но глюкокортикоид оказывает значительное воздействие после лечения. Конкретные антител

Herpes simplex virus (HSV) is the most common pathogen of infectious encephalitis, accounting for nearly half of the confirmed cases of encephalitis. Its clinical symptoms are often atypical. HSV PCR in cerebrospinal fluid is helpful for diagnosis, and the prognosis is usually satisfactory after regular antiviral treatment. Interestingly, some patients with …

[Neonatal ophthalmia caused by Herpes Simplex Virus type I].

UNLABELLED: There are different etiologies of neonatal ophthalmia such as viral ones. Among them, the Herpes simplex virus, both type I and II, is particularly relevant due to its potential severity. It is a rare, in frequent entity, but with a high rate of morbidity and mortality without appropriate diagnosis and management. OBJECTIVE: To describe a case of neonatal ophthalmia caused by Herpes Virus type I, its clinical characteristics, and correct diagnosis. CLINICAL CASE: 8-days old newborn, with no notable history, presenting edema and erythema of eyelids, accompanied by bilateral ocular…

Herpes simplex virus esophagitis-clinical challenges in the elderly.

A 77-year-old woman presented with a 2-week history of malaise, prostration, anorexia, abdominal pain, vomiting and diarrhoea. She had been taking systemic corticosteroids for the past year. During hospitalisation, renal insufficiency, ionic changes and liver function abnormalities were detected and corrected. However, the patient developed total dysphagia. UGE revealed multiple shallow ulcers below the cricopharyngeal level and in the distal oesophagus, with normal-appearing intervening mucosa. Histological examination allowed the diagnosis of herpes simplex virus esophagitis. Treatment with …

Lignosulfonate Rapidly Inactivates Human Immunodeficiency and Herpes Simplex Viruses.

Background: Very few studies of the antiviral potential of lignosulfonates have been published. With the aim of oral application, among various groups of natural products, the relative antiviral potency of lignosulfonate and its ability to rapidly inactivate viruses were investigated. Methods: As target cells, MT-4 cells in suspension and attached Vero cells were used for infections with human immunodeficiency virus (HIV) and human herpes simplex type-1 virus (HSV). Mock- or virus-infected cells were incubated for 3-5 days with various concentrations of test samples, and the viable cell number…

Untreated herpes simplex virus encephalitis without a fatal outcome.

Herpes simplex virus encephalitis (HSE) is the most common sporadic fatal encephalitis. Although timely administered acyclovir treatment decreases mortality, neuropsychiatric sequelae is still common among survivors. Magnetic resonance imaging is frequently utilized for the diagnosis of HSE, which typically involves temporal lobe(s) and can be mixed with brain tumors involving the same area. Here, we report a case of HSE, who received acyclovir with a delay of 90 days because of presumptive tumor diagnosis and survived with minimal sequelae.

Mortality from neonatal herpes simplex viremia causing severe hepatitis.

Neonatal herpes simplex viral infections are rare in the setting of appropriate prenatal care; however, under circumstances where prenatal care is not delivered, these infections can lead to significant disease. We report a fatal case of herpes simplex virus with severe herpes hepatitis in a 14-day old male neonate. The clinical history was limited and nonspecific, however there was no prenatal care and a known history of drug abuse in the family. Autopsy revealed extensive necrosis and hemorrhage of the liver and cerebellum. Histologically, the liver revealed viral intranuclear ground glass i…

[Recurrent lymphocytic meningitis by herpes simplex virus type 2].

Recurrent lymphocytic meningitis or Mollaret's meningitis is a rare condition caused by a number of infectious, autoimmune, toxic and neoplastic diseases. Herpes simplex type 2 is the most commonly isolated agent. It usually compromises middle aged women, with a self-limited clinical presentation that resolves within a week leaving no sequelae. Its diagnosis is mainly based on nucleic acid detection on cerebrospinal fluid. Antiviral prophylaxis has not shown conclusive to avoid recurrences.

A Preclinical Model for Studying Herpes Simplex Virus Infection.

Herpes simplex virus (HSV) infections can cause considerable morbidity. Currently, nucleoside analogues such as acyclovir are widely used for treatment. However, HSV infections resistant to these drugs are a clinical problem among immunocompromised patients. To provide more efficient therapy and to counteract resistance, a different class of antiviral compounds has been developed. Pritelivir, a helicase primase inhibitor, represents a promising candidate for improved therapy. Here, we established an HSV-1 infection model on microneedle-pretreated human skin ex vivo. We identified HSV-1-specifi…

Herpes Simplex Virus Infection in Infants Undergoing Meningitis Evaluation.

BACKGROUND: Although neonatal herpes simplex virus (HSV) is a potentially devastating infection requiring prompt evaluation and treatment, large-scale assessments of the frequency in potentially infected infants have not been performed. METHODS: We performed a retrospective cross-sectional study of infants ≤60 days old who had cerebrospinal fluid culture testing performed in 1 of 23 participating North American emergency departments. HSV infection was defined by a positive HSV polymerase chain reaction or viral culture. The primary outcome was the proportion of encounters in which HSV infecti…
