Common severe infections include encephalitis read more in adults and Overview of Neonatal Infections Overview of Neonatal Infections Neonatal infection can be acquired In utero transplacentally or through ruptured membranes In the birth canal during delivery (intrapartum) From external sources after birth (postpartum) Common read more .). Women with first-episode primary infection lack antibodies to both HSV-1 and HSV-2, and these mothers are at the greatest risk of transmitting HSV to their infant. The number of cases per 100,000 live births in Western Europe (France 1.15, United Kingdom 1.65, and the Netherlands 3.2)70-72is lower than reported for Scandinavia (Sweden 6.5)73and North America (USA 9.6 and Canada 5.9). Transplacental transmission before the 20th week of pregnancy may cause spontaneous abortion in as many as 25% of cases. Pharmacokinetics and safety of extemporaneously compounded valacyclovir oral suspension in pediatric patients from 1 month through 11 years of age. Accessibility Neonatal herpes simplex presenting as a zosteriform eruption Population-based surveillance of neonatal herpes simplex virus infection in Australia, 1997-2011. There is no clear pattern of signs and symptoms that identifies babies with neonatal HSV disease, meaning a high index of suspicion is required. Specialist obstetric and paediatric advice on management and anticipatory guidance should be sought for a woman with a history of genital herpes and active lesions at term and especially in the high-risk situation of a first episode within 6 weeks of delivery. Early in the clinical course, some neonates with HSV infection may present with persistent fever and negative bacterial cultures. The .gov means its official. The use of suppressive therapy in pregnant females with a history of genital herpes has reduced the chance of having active lesions at time of delivery and decreased periods of subclinical viral shedding. As neonatal HSV infection may occur in the absence of skin lesions, other diagnostic specimens are required. Oral Acyclovir Suppression and Neurodevelopment after Neonatal Herpes One study attempted to evaluate the pharmacokinetics of valacyclovir down to one month of age, but recommendations could not be provided as only one dose was studied and those less than 3 months were noted to have decreased clearance (Kimberlin et al., 2010). Clinical management guidelines for obstetrician-gynecologists. HSV PCR swabs should be obtained from eyes (conjunctiva), mouth, nasopharynx, umbilicus, urine and rectum. Melvin AJ, Mohan KM, Schiffer JT, Drolette LM, Magaret A, Corey L, Wald A, 2015. Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication. Neonatal herpes simplex virus infection (HSV) is rare in neonates, with an estimated global incidence of 10 per 100,000 live births. Other infectious agents that might be considered are toxoplasmosis, rubella and syphilis. Herpes simplex virus (HSV) infection occurs infrequently in neonates despite the ubiquitous nature of the virus in adults. The Acquisition of Herpes Simplex Virus during Pregnancy Neonatal infection is usually the result of HSV 2, as this is the main virus associated with genital infection. Neonatal herpes simplex virus infection is usually transmitted during delivery. Strong clinical suspicion, timely diagnosis, and early antiviral treatment are critical to improving outcome. Neonatal HSV infection causes serious morbidity and mortality and leaves many survivors with permanent sequelae. It is advised, however, that any pregnant woman known or presumed to be negative for HSV should remain abstinent during her third trimester if in a relationship with a known seropositive partner (Bulletins, 2007). Arch Dis Child. Suppressive therapy with oral acyclovir for 6 months has demonstrated a decrease in recurrences and has improved developmental outcomes. After this regimen, infants with CNS disease are given oral acyclovir 300 mg/m2 3 times a day for 6 months; this long-term regimen improves neurodevelopmental outcomes at 1 year of age but may cause neutropenia. Neonates with central nervous system (CNS) involvement were enrolled in one. Neonatal herpes simplex virus infection is usually transmitted during delivery. Management of neonatal herpes simplex virus infection. Careers, Unable to load your collection due to an error. Symptoms are non-specific and a high index of suspicion is required. HSV can transmit through intact membranes. An official website of the United States government. Infants born to women with primary (ie, first episode) genital HSV infection near the time of delivery are known to be at much greater risk of developing neonatal herpes than are infants who are born to women with recurrent genital HSV infection near the time of delivery (25%-60% vs <2%, respectively). Intrauterine herpes simplex virus infections, Neonatal herpes simplex virus infection: epidemiology and treatment. Plasma and cerebrospinal fluid herpes simplex virus levels at diagnosis and outcome of neonatal infection, Pathological findings of adenine arabinoside (ARA-A) and cytarabine (ARA-C) in the treatment of herpes simplex encephalitis in rabbit model, Antiviral Therapies for Herpesviruses: Current Agents and New Directions. Avoid using scalp electrodes where there is a suspicion of active maternal HSV. An opening line such as, many parents wonder about is this a concern for you? is useful for normalising parental queries. The index of suspicion is heightened by progressive abnormalities of liver function, particularly during the first week of life. Neonates with no skin vesicles usually present with localized central nervous system (CNS) disease. In neonates with isolated skin or mucosal disease, progressive or more serious forms of disease frequently follow within 7 to 10 days if left untreated. Risk factors for HSV transmission to neonate: Type of maternal infection [first-episode primary (57%) > first-episode non-primary (25%) > recurrent (<2%)] Consequently, repeat lumbar puncture is recommended when laboratory tests are negative but clinical suspicion remains high. All infants with central nervous system involvement require repeat lumbar puncture(s) to assess for clearance of the virus prior to stopping intravenous therapy (James and Kimberlin, 2015b). The disseminated disease develops in about one-quarter of neonates with HSV infection. Particular care when handling the baby must be taken by those with recently acquired or reactivated oral or other skin lesions. HSV is composed of 4 parts: a viral double-stranded DNA genome with a long and short component, icosahedral capsid comprised of 162 capsomeres, a protein layer surrounding the capsid often referred to as the tegument, and an envelope comprised of 11 glycoproteins which are used for attachment and penetration of the virus into host cells (Whitley and Roizman, 2001). Mothers of neonates with HSV infection tend to have newly acquired genital infection, but many have not had symptoms at the time of delivery. Epub 2013 May 25. No recommendations currently exist for screening asymptomatic pregnant women for HSV by serology. Toll Free Phone: 0508 11 12 13 Thus, although treating an infant with neonatal herpes is a relatively rare occurrence, managing infants potentially exposed to HSV at the time of delivery occurs more frequently. Most neonatal HSV infections are acquired at birth, generally from mothers with an unrecognised genital herpes infection acquired during pregnancy. Whole blood PCR should also be performed to assist with the diagnosis of neonatal HSV infection. Philadelphia, Current Medicine, 1998. Kimberlin DW, Jacobs RF, Weller S, van der Walt JS, Heitman CK, Man CY, Bradley JS, 2010. While some have been able to demonstrate immunogenicity, none have made it to licensure yet (Whitley and Baines, 2018). These risk factors include the mothers type of infection (first-episode primary, first-episode non-primary, or recurrent infection, as defined below), maternal serologic status (when available), HSV typing of genital lesion, isolation of HSV at delivery, vaginal versus cesarean delivery, duration of rupture of membranes, and use of fetal scalp electrodes (Pinninti and Kimberlin, 2013). This allows for serologic results and viral lesion HSV type to be compared, and thus, determine maternal infection type. Failure of antepartum maternal cultures to predict the infants risk of exposure to herpes simplex virus at delivery. Whitley R, Arvin A, Prober C, Burchett S, Corey L, Powell D, Plotkin S, Starr S, Alford C, Connor J, et al., 1991. Diagnosis is clinical and usually confirmed by laboratory testing. The mortality rate of 7.9% from the present study is within the range of 4-17.1% reported from studies . Dropulic LK, Oestreich MC, Pietz HL, Laing KJ, Hunsberger S, Lumbard K, Garabedian D, Turk SP, Chen A, Hornung RL, Seshadri C, Smith MT, Hosken NA, Phogat S, Chang LJ, Koelle DM, Wang K, Cohen JI, 2019. 1 Empiric acyclovir may be . o [ pediatric abdominal pain ] Neonatal conjunctivitis is watery or purulent ocular drainage due to a chemical irritant or a pathogenic organism. Such screening would not likely be of use in predicting infants at high risk of neonatal HSV infection because it cannot reliably identify primary infections (Prober et al., 1988). Notify the infants lead maternity caregiver and general practitioner of risk. Also check the mothers total and type-specific HSV serological status, to confirm that this is a first episode of genital herpes and not a recurrence. HSV-specific IgM concentrations increase rapidly during the first 2 to 3 months, and in some infants may be detectable for as long as one year following neonatal infection. Management of herpes in pregnancy, Herpes Simplex Virus DNAemia Preceding Neonatal Disease. In the setting of persistently positive CSF HSV PCR results beyond 21 days of therapy, intravenous acyclovir should be discontinued only after a negative CSF HSV PCR is achieved. doi: 10.1371/journal.pntd.0010861. Infants usually present between 10 days and 4 weeks of age with symptoms of fever or temperature instability, lethargy, poor feeding and irritability, followed by seizures, bulging fontanelle and focal neurological signs.

An estimated 25 to 65% of pregnant women in the United States have genital infection with herpes simplex virus type 1 (HSV-1) or HSV type 2 . There is no clear pattern of signs and symptoms that identify babies with neonatal HSV disease, meaning a high index of suspicion is required. Neonatal HSV infection causes serious morbidity and mortality and leaves many survivors with permanent sequelae. This neonate with AIDS also has disseminated HSV-2 infection with lesions covering the entire body. Only about 40% of affected neonates will initially have skin lesions and most lack a parental history of genital herpes. Universal screening has not been recommended or shown to be effective, and most maternal infections with risk of transmission are asymptomatic. Infected neonates will produce HSV-specific IgM antibodies (as detected by immunofluorescence) within three weeks of acquisition of the viral infection. Advise parents regarding any transmission precautions with regard to other siblings and family members, otherwise, parents may initiate precautions they imagine to be necessary. Herpes simplex virus (HSV) transmitted from mother to child around the time of delivery can cause potentially fatal disease in the newborn. New Zealand, Copyright Guidance on management of asymptomatic neonates born to women with active genital herpes lesions. Symptoms generally develop in the first 14 days of life. Accessibility Clusters of vesicles on an erythematous base are characteristic and may be present on almost any part of the body. An ophthalmology consultation should be sought in suspected or confirmed cases of neonatal HSV infection, to help identify and monitor ocular complications that may arise during the illness. Performing viral cultures on pregnant women with a history of HSV disease is also not warranted antepartum as women with asymptomatic viral shedding are at lower risk of transmitting the virus than in those women with primary infection (Arvin et al., 1986; Prober et al., 1988). Neonatal herpes simplex virus infection: epidemiology and treatment. The main risk of transmission to the neonate is at delivery, where contact with HSV-infected secretions in the birth canal accounts for most neonatal HSV infection.46 The site of entry is usually the eye, nasopharynx or an abrasion secondary to scalp electrodes or forceps.
