Summaries for Encephalopathy, Acute, Infection-Induced 1

OMIM : 58 Herpes simplex virus (HSV)-1 is most often associated with infection of the oral mucosa. Primary infection is most commonly asymptomatic, but it may lead to symptoms usually involving the mucosa and skin. Following replication at the infection site, HSV-1 enters the epithelial endings of sensory neurons and travels up the trigeminal cranial nerves to the trigeminal ganglia, where latent infection is established. Reactivation of HSV-1, usually in the form of herpes labialis (cold sores), may occur in 20 to 40% of the population. HSV-1 seroprevalence is high, with over 85% of adults between the ages of 20 and 40 years infected. HSV-1 rarely infects the central nervous system (CNS), resulting in herpes simplex encephalitis (HSE), with an incidence of 2 to 4 per 1,000,000 people per year. In HSE, HSV-1 invades and replicates in neurons and glial cells, where focal necrotizing infections occur, primarily affecting the temporal and subfrontal regions of the brain. Untreated, HSE is fatal in at least 70% of cases, although the mortality and morbidity have been drastically reduced with antiviral therapy. Approximately one-third of all HSE cases are due to primary infections, and 30% of all HSE cases occur in children under the age of 20 years. Among children, HSE peaks between 3 months and 3 years of age, coinciding with the time of primary infection. In a subset of children, HSE results from a series of monogenic primary immunodeficiencies that impair UNC93B1- and TLR3 (603029)-dependent production of IFNA (147660)/IFNB (147640) and IFNG (147570) in the CNS (summary by Sancho-Shimizu et al., 2007).

UniProtKB/Swiss-Prot : 76 Encephalopathy, acute, infection-induced, Herpes-specific, 1: A rare complication of human herpesvirus 1 (HHV-1) infection, occurring in only a small minority of HHV-1 infected individuals. It is characterized by hemorrhagic necrosis of parts of the temporal and frontal lobes. Onset is over several days and involves fever, headache, seizures, stupor, and often coma, frequently with a fatal outcome.
