The majority (85%) of infected infants have no signs of infection in the newborn period, and when sequelae such as a hearing deficit or neurological impairment manifest themselves, the possibility of a CMV infection is easily overlooked. Neonatal herpes simplex virus (HSV) infection is a rare but devastating infection. Improvements with regard to outcome have been achieved by antiviral treatment, but the morbidity remains unacceptably high in children following neonatal HSV encephalitis. The general aim of the thesis is to increase the knowledge of childhood morbidity related to CMV and HSV infections.

Berger, MD; Sidney Houff, MD, PhD erpes simplex virus type 2 (HSV-2) infection is responsible for significant neurologi- cal morbidity, perhaps more than any other virus.

Wolf,1,* Kristin M. Rogers,3 Earl L. Blewett,4 Dirk P. Dittmer,2 Farnaz D. Fakhari,2 Corey A. Hill,3 Stanley D. Kosanke,1 Gary L. White,1 and Richard Eberle3 Here we describe the unusual finding of herpesvirus pneumonia in a 7-d-old infant baboon Papio( hamadryas anubis). This animal had been separated from its dam the morning of its birth and was being hand-reared for inclusion in a specific- pathogen-free colony. The baboon was presented for anorexia and depression of 2 d duration. Physical examination revealed a slightly decreased body temperature, lethargy, and dyspnea. The baboon was placed on a warm-water blanket and was given amoxicillin–clavulanate orally and fluids subcutaneously. The animal’s clinical condition continued to deteriorate despite tube feeding, subcutaneous fluid administration, and antibiotic therapy, and it died 2 d later. Gross necropsy revealed a thin carcass and severe bilateral diffuse pulmonary consolidation. Histopathology of the lung revealed severe diffuse necrotizing pneumonia. Numerous epithelial and endothelial cells contained prominent intranuclear herpetic inclusion bodies. Virus isolated from lung tissue in cell culture was suspected to be Herpesvirus papio 2 (HVP2) in light of the viral cytopathic effect. Real-time polymerase chain reaction (PCR) analysis and DNA sequencing of PCR products both confirmed that the virus was HVP2.

  • Herpes Simplex Virus (Last Updated June 27, 2018; Last Reviewed June 27, 2018)
    Herpes Simplex Virus (Last updated June 27, 2018; last reviewed June 27, 2018) Panel’s Recommendations I. Will condoms (compared with not using condoms) prevent herpes simplex virus (HSV) infection in sexually active adolescents and young adults with HIV? • Condoms should be used to prevent HSV infection (and other sexually transmitted diseases) in adolescents and young adults with HIV (strong; low). The data regarding the level of protection provided by condoms are very limited for individuals with HIV in general, and for youth specifically. II. Will adolescents and young adults with HIV who have recurrent, genital HSV infection benefit from suppressive anti-HSV antiviral therapy (compared with not using suppressive therapy)? • Adolescents and young adults with HIV who suffer severe, frequent, and/or troubling recurrent genital HSV infection will benefit from anti-HSV suppression therapy (strong; moderate). III. Should children and adolescents with HIV who have severe primary or recurrent HSV (genital or orolabial) infection receive intravenous (IV) acyclovir (compared with receiving oral antiviral therapy)? • Children and youth with HIV who have severe mucocutaneous HSV infections should be treated with IV acyclovir. When improvement is noted, they can be switched to oral therapy until healing is complete (strong; moderate). IV. Should children and adolescents with HIV be treated with oral acyclovir, valacyclovir, or famciclovir for non-severe primary episodes or recurrent episodes of orolabial or genital HSV (compared with no antiviral therapy)? • Oral anti-HSV drugs will shorten the duration and reduce the severity of non-severe HSV infections in children and adolescents with HIV. Oral valacyclovir and famciclovir have superior pharmacokinetic profiles compared with oral acyclovir (strong; moderate).

  • Neonatal Herpes: What Lessons to Learn
    CASE REPORT Neonatal herpes: what lessons to learn KL Hon 韓錦倫 TF Leung 梁廷勳 Vesicular rashes in neonates are challenging in terms of diagnosis and management. Herpes 張漢明 HM Cheung infection is an important diagnostic consideration. We report two illustrative neonatal cases 陳基湘 Paul KS Chan of herpesvirus infections with vesicular rashes. Such babies may be remarkably asymptomatic. A high index of suspicion leading to a prompt diagnosis, timely quarantine measures, and institution of antiviral treatment are pivotal for desirable outcomes. Case reports Case 1 An afebrile and asymptomatic neonate with 39 weeks and 6 days of gestation received a 5-day course of intravenous penicillin and gentamicin, because of prolonged rupture of maternal membranes and a slightly elevated plasma C-reactive protein level (14.6 mg/L; reference level, <10 mg/L). He developed a vesicular rash on day 12 of life, initially involving the face and forehead that subsequently spread to the entire body. Spontaneous rupture of the vesicles yielded yellow non-purulent fluid. He was admitted to a newborn unit (Fig 1), and cared for in a cubicle. The mother had childhood chickenpox, and developed some vesicles (which became crusted) on the dorsum of her right hand and arm 2 days before delivery. As chickenpox is an air-borne infection, the neonate was immediately transferred to an isolation room. He was treated as having herpes or a bacterial skin infection with acyclovir plus intravenous ampicillin and cloxacillin, and remained asymptomatic. Immunofluorescence staining of vesicular fluid confirmed the presence of varicella-zoster virus (VZV). Consequently, one cubicle of the newborn unit (involving 12 babies and their parents) was quarantined.

Kousoulas 2,3,*, Agustin Fernandez 3 and Edward Gershburg 3,* 1 Department of Pathobiological Sciences, School of Veterinary Medicine, Louisiana State University, Baton Rouge, LA 70803, USA; [email protected] 2 Division of Biotechnology and Molecular Medicine, Louisiana State University, Baton Rouge, LA 70803, USA 3 Rational Vaccines Inc., Woburn, MA 01801, USA; [email protected] * Correspondence: [email protected] (K.G.K.); [email protected] (E.G.) Abstract: Diseases caused by human herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) affect millions of people worldwide and range from fatal encephalitis in neonates and herpes keratitis to orofacial and genital herpes, among other manifestations. The viruses can be shed efficiently by asymptomatic carriers, causing increased rates of infection. Viral transmission occurs through direct contact of mucosal surfaces followed by initial replication of the incoming virus in skin tissues. Subsequently, the viruses infect sensory neurons in the trigeminal and lumbosacral dorsal root ganglia, where they are primarily maintained in a transcriptionally repressed state termed “latency”, which persists for the lifetime of the host. HSV DNA has also been detected in other sympathetic ganglia. Periodically, latent viruses can reactivate, causing ulcerative and often painful lesions primarily at the site of primary infection and proximal sites. In the United States, recurrent genital herpes alone accounts for more than a billion dollars in direct medical costs per year, while there are much higher costs associated with the socio-economic aspects of diseased patients, such as loss of productivity due to mental anguish.
