Abstract
Viral infections in pregnancy are major causes of maternal and fetal morbidity and mortality. Infections can develop in the neonate transplacentally, perinatally, or postnatally (from breast milk or other sources) and lead to different clinical manifestations, depending on the viral agent and the gestational age at exposure. Viewing the peculiar tolerogenic status which characterizes pregnancy, viruses could exploit this peculiar immunological status to spread or affect the maternal immune system, adopting several evasion strategies. In fact, both DNA and RNA virus might have a deep impact on both innate and acquired immune systems. For this reason, investigating the interaction with these pathogens and the host's immune system during pregnancy is crucial not only for the development of most effective therapies and diagnosis but mostly for prevention. In this review, we will analyze some of the most important DNA and RNA viruses related to gestational infections.

Top 10 Pearls for the Recognition, Evaluation, and Management of Maternal Sepsis. Obstet Gynecol 2021; 138:289-304.

Abstract
Maternal sepsis is a leading cause of preventable maternal mortality that requires early recognition, expedient evaluation, and appropriate management. Maternal sepsis is an obstetric emergency and a leading cause of maternal morbidity and mortality. Early recognition in a pregnant or postpartum patient can be a challenge as the normal physiologic changes of pregnancy may mask the signs and symptoms of sepsis. Bedside assessment tools may aid in the detection of maternal sepsis. Timely and targeted antibiotic therapy and fluid resuscitation are critical for survival in patients with suspected sepsis. Once diagnosed, a search for etiologies and early application of source control measures will further reduce harms. If the patient is in septic shock or not responding to initial treatment, multidisciplinary consultation and escalation of care is necessary. Health care professionals should be aware of the unique complications of sepsis in critically ill pregnant and postpartum patients, and measures to prevent poor outcomes in this population. Adverse pregnancy outcomes may occur in association with sepsis, and should be anticipated and prevented when possible, or managed appropriately when they occur. Using a standardized approach to the patient with suspected sepsis may reduce maternal morbidity and mortality.

Seroprevalence of ToRCH Pathogens in Southeast Asia. Microorganisms 2021; 9:microorganisms9030574.

Abstract
ToRCH is the acronym for several pathogens associated with pregnancy complications and sequelae in the unborn or newborn child. Particularly primary infections during pregnancy are associated with increased risk. Seroprevalence data of ToRCH infections are important, especially in countries with weak disease surveillance systems, to estimate immunity and vaccination levels, as well as exposure rates and thus the risk of infection during pregnancy. A systematic literature search spanning a 30-year time period was conducted to identify serosurveys on ToRCH pathogens in Southeast Asia. The 96 identified studies showed that some pathogens were well studied, while only limited data were available for others. Studies from the better-developed countries of the region were more abundant. Moreover, seroprevalence data were often limited to a certain geographical region within the country or to certain cohorts, there was an evident lack of recent serosurveys, and the study quality was often not adequate. Well-designed and area-wide serosurveys of ToRCH pathogens are clearly warranted. If combined with risk factor analysis, these studies may guide the development and implementation of effective measures for infection prevention, especially during pregnancy. In addition, educational programs for health care workers and for pregnant women during antenatal care are urgently needed.

Abstract
Varicella is a highly contagious, infectious disease caused by the varicella-zoster virus. Those at higher risk of severe complications are immunocompromised individuals, adults, non-immune pregnant women, and newborns. According to the gestational time, when varicella-zoster virus infection is acquired during pregnancy, serious complications can potentially occur for both the woman and the fetus. The present study was conducted to assess the profile of varicella susceptibility in pregnant women in Apulia, a large region in Southern Italy, from 2016 to 2019. The data showed that pregnant women between the age of 15-24 and 40-49 years, the youngest and the oldest, respectively, are the most protected against varicella-zoster virus infection, exceeding the prevalence rate of 90%. Conversely, pregnant women between the age of 25 and 34 years seem to be the most vulnerable and the most at risk for acquiring varicella-zoster virus infection during pregnancy. Analysis of the immunity status against varicella should be introduced as a screening test before pregnancy, together with a strategic vaccination campaign targeting non-immune women of childbearing age, in order to reduce the risk of congenital and perinatal varicella.

Abstract
There are inconsistencies in how newborns are managed following exposure to varicella, ranging from reassurance and observation to administration of varicella zoster immunoglobulin (VZIG) and admission to hospital for varying length courses of intravenous aciclovir.Hospitalised preterm babies exposed to varicella should receive VZIG. Administration can otherwise be limited to pregnant non-immune women or to newborns if there is development of maternal chickenpox from 5 days prior to delivery up to 48 hours postdelivery. Intravenous aciclovir is only recommended in cases of newborn disease despite VZIG or in severe disease. The use of VZIG may not prevent varicella but may reduce severity of disease.In this article, we review the evidence for risk to non-immune mothers, the fetus and newborns who had different types of exposure to varicella, with recommendations for management and treatment of confirmed neonatal chickenpox.

Abstract
Background Herpes simplex virus (HSV)-1 and HSV-2 are common infections affecting the global population, with HSV-1 estimated to affect 67% of the global population. HSV can have rare but severe manifestations, such as encephalitis and neonatal herpes, necessitating the use of reliable and accurate diagnostic tools for the detection of the viruses. Currently used HSV diagnostic tools require highly specialized skills and availability of a laboratory setting but may lack sensitivity. The numerous recently developed HSV diagnostic tools need to be identified and compared in a systematic way to make the best decision about which diagnostic tool to use. The diagnosis of HSV is essential for prompt treatment with antivirals. To select the best test for a patient, knowledge of the performance and limitations of each test is critical. Objective This systematic review has summarized recent studies evaluating HSV-1 and HSV-2 diagnostic tools. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, selection criteria, data extraction, and data analysis were determined before the commencement of the study. Studies assessing the specificity/sensitivity of HSV-1 or HSV-2 diagnostic tools published between 2012 and 2018 were included. Quality assessment of included studies was performed using the quality assessment of diagnostic accuracy studies (QUADAS-2) tool. Results Searches of the PubMed database yielded 264 studies; 11 studies included 11 molecular assays, and 8 studies included 19 different serological assays for the detection of HSV-1, HSV-2, or both. A greater proportion of molecular assay–based tools are being developed by commercial entities. Studies that tested molecular assays mostly focused on cutaneous and mucosal HSV infections (n=13); 2 studies focused on ocular disease, whereas only 1 study focused on the central nervous system manifestations. The Simplexa HSV 1 & 2 Direct is currently the only Food and Drug Administration–approved device for use on cerebrospinal fluid. No tools focused on prenatal screening. We also present performance metrics of tests for benchmarking of future technology. Most of the included studies had a high risk of bias rating in half of the QUADAS-2 tool risk of bias domains. Conclusions The use of serologic tests to diagnose genital lesions is inappropriate because positive results may be due to chronic infection, whereas negative results may overlook recent infection. The incidence of acute infections is rising. As these infections present the greatest risk to fetuses, work needs to be done to prevent vertical transfer. Prenatal screening for primary infection and subsequent medical intervention will assist in lowering the rate of neonatal herpes. In conclusion, HSV diagnosis is moving away from culture-based methods to serology-based or polymerase chain reaction–based methods. Sensitive, rapid, and efficient HSV diagnostic tools should be adopted for the prevention of acute infections and neonatal herpes.

Abstract
Infections with the herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) as well as with the varicella-zoster virus (VZV) may take a serious course. Thus, rapid and reliable detection of these alphaherpesviruses is urgently needed. For this, we established a qualitative quadruplex real-time polymerase chain reaction (PCR) covering HSV-1, HSV-2, VZV and endogenous human glyceraldehyde 3-phosphate dehydrogenase (GAPDH). The PCR was validated with quality assessment samples and pre-characterized clinical samples including swabs, blood and cerebrospinal as well as respiratory fluids. For comparison, nucleic acids (NA) of selected samples were extracted manually and automatically. The protocol takes approx. 90 min, starting with the preparation of NA until the report of results. The oligonucleotide and hydrolysis probe sequences specifically detect and distinguish HSV-1 (530 nm), HSV-2 (705 nm) and VZV (560 nm) DNA. The detection limit was estimated with 100-500 copies/ml HSV-1 and HSV-2/VZV, respectively. All quality assessment samples as well as all the patient samples were classified correctly. Parallel detection of GAPDH (670 nm) DNA was implemented to demonstrate correct sampling, but was uncertain in case of swabs. To this end, alphaherpesvirus-free human DNA was also added directly into the mastermix to exclude PCR inhibition. The established protocol for parallel detection and differentiation of alphaherpesviruses is fast, highly specific as well as rather sensitive. It will facilitate HSV-1/2 and VZV diagnostics and may be further improved by opening the 670 nm channel for a combined extraction and PCR inhibition control.

Abstract
In countries where vaccination is not implemented, varicella is a common ubiquitous disease offering a broad range of clinical presentations. Whereas mother-to-child perinatal transmission of varicella zoster virus (VZV) can lead to disseminated life-threatening diseases in unimmunised newborns, postnatal acquisition will be generally a source of milder infections. The pattern and severity of the disease are known to be partly determined by the timing of VZV acquisition during pregnancy with the highest risk period located around delivery. Management of youngest children after contact with a varicella case remains difficult for clinicians not only because of unawareness of varicella natural history and risks factors for serious complications, but also because of the lack of consensus from experts available in the literature. This state of uncertainty often leads to overconsumption of healthcare resources with systematic hospitalisation and unjustified antiviral intravenous therapies. After a concise literature review, this article proposes pragmatic recommendations considering newborns in various scenarios following a contact with VZV, taking into account the timing and mode of virus transmission, the maternal immunological status, the baby's gestational age and the presence of other underlying conditions.

Abstract
Congenital and perinatal infections represent major causes of permanent disability among children worldwide. Linked together by the acronym TORCH, denoting Toxoplasma gondii, rubella virus, cytomegalovirus, and herpes virus, congenital infections can result from only a modest number of human pathogens that cross the placenta and infect the fetus. Although congenital rubella syndrome has been eliminated in the Americas by immunization, several pathogens discussed in this chapter cannot currently be prevented by vaccines or effectively treated with the available antimicrobial drugs. Due to the immaturity of the immune system, newborn infants are at risk for postnatally acquired infections with certain viruses and several bacteria. This chapter summarizes the epidemiology, pathogenesis, clinical manifestations, diagnosis, treatment, and prevention of selected pathogens that can damage the developing nervous system. As emphasized by the persisting challenges of preventing congenital cytomegalovirus infection and the emergence of severe brain damage associated with congenital Zika syndrome, these pathogens remain important causes of cerebral palsy, epilepsy, and intellectual disability.

Abstract
Purpose: Hepatitis due to herpes simplex virus (HSV) during pregnancy is rare, it is often not included in the differential disease. However, hepatitis leads to maternal death; hence, early diagnosis is necessary. Hepatic enzyme elevation in late pregnancy is often associated with obstetric-related diseases, such as acute gestational fatty liver and HELLP syndrome (hemolytic anemia, elevated liver enzymes, low platelet count). These pregnancy-related diseases often improve maternal condition after completion of pregnancy, but in patients with HSV hepatitis, invasive treatment, such as cesarean section, may lead to deterioration of maternal condition after completion of pregnancy. A systematic review was conducted to extract necessary factors to avoid maternal death caused by herpetic hepatitis.Methods: In 24 cases reported since 1991, age, onset gestational weeks, initial symptoms, days from onset of symptoms to consultation, diagnosis method, treatment method, maximum liver escape enzyme value during hospitalization, bilirubin value, international normalized ratio value, and fetal/neonatal prognosis were extracted, and the relationship between maternal death group (n = 6) and maternal alive group (n = 18) was statistically analyzed.Results: Fever as an initial symptom was observed in all cases. Maternal death did not occur in patients administered with acyclovir (ACV) as empiric therapy. No difference was found between the two groups in other factors.Conclusion: Early diagnosis and treatment of herpetic hepatitis during pregnancy are important, as well as administration of empiric ACV concurrently with noninvasive diagnosis when a pregnant woman has elevated liver enzyme accompanied by fever in late pregnancy.

Abstract
Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Sepsis can be caused by a broad range of pathogens; however, bacterial infections represent the majority of sepsis cases. Up to 42% of sepsis presentations are culture negative, suggesting a non-bacterial cause. Despite this, diagnosis of viral sepsis remains very rare. Almost any virus can cause sepsis in vulnerable patients (e.g., neonates, infants, and other immunosuppressed groups). The prevalence of viral sepsis is not known, nor is there enough information to make an accurate estimate. The initial standard of care for all cases of sepsis, even those that are subsequently proven to be culture negative, is the immediate use of broad-spectrum antibiotics. In the absence of definite diagnostic criteria for viral sepsis, or at least to exclude bacterial sepsis, this inevitably leads to unnecessary antimicrobial use, with associated consequences for antimicrobial resistance, effects on the host microbiome and excess healthcare costs. It is important to understand non-bacterial causes of sepsis so that inappropriate treatment can be minimised, and appropriate treatments can be developed to improve outcomes. In this review, we summarise what is known about viral sepsis, its most common causes, and how the immune responses to severe viral infections can contribute to sepsis. We also discuss strategies to improve our understanding of viral sepsis, and ways we can integrate this new information into effective treatment.

Abstract
Chickenpox is a highly contagious disease caused by primary infection of varicella zoster virus (VZV). The disease is spread worldwide and is usually benign but, in some groups of population like pregnant women, can have a severe outcome. Due to a not optimal vaccination coverage, a relatively high number of childbearing-aged women in a European country such as Italy tested seronegative for VZV and so are currently at risk of acquiring chickenpox during pregnancy, especially if they live in contact with children for family or work reasons. Only few data are available about the risk of infection in this setting: the incidence of chickenpox may range from 1.5 to 4.6 cases/1000 childbearing females and from 1.21 to 6 cases/10,000 pregnant women, respectively. This review is aimed to focus on the epidemiology and the clinical management of exposure to chickenpox during pregnancy. Particular emphasis is given to the accurate screening of childbearing women at the time of the first gynecological approach - the females who tested susceptible to infection can be counseled about the risks and instructed on procedure should contact occur - and to the early prophylaxis of the at-risk exposure. Lastly, the achievement of adequate vaccination coverage of the Italian population remains a cornerstone in the prevention of chickenpox in pregnancy.

Abstract
The acronym TORCH is used to refer to congenital infections, such as toxoplasmosis, other infections (such as syphillis, varicella-zoster, and parvovirus B19), cytomegalovirus, and herpes simplex virus. The classic findings in patients with TORCH infections include rash in the mother during pregnancy and ocular findings in the newborn. Zika virus has emerged as an important worldwide congenital infection. It fits well with other congenital TORCH infections since there is a rash in the mother and there are commonly ocular abnormalities in the newborn. TORCH infections are recognized to have neurologic effects, such as ventriculomegaly, intraventricular adhesions, subependymal cysts, intracerebral calcifications, and microcephaly; however, the Zika virus is intensely neurotropic. Thus, it targets neural progenitor cells, leading to a more severe spectrum of central nervous system abnormalities than is typically seen in other TORCH infections, while relatively sparing the other organ systems. In this review, nonspecific findings of congenital infections initially will be described, then individual TORCH infections will be described and compared with the imaging findings associated with congenital Zika virus infection. For the radiologist, awareness of imaging features of common congenital infections may facilitate early diagnosis and may, at times, lead to prompt initiation of therapy. Online supplemental material is available for this article.

Abstract
We present an unusual case of varicella zoster (VZ) virus IgG negative, yet clinically apparent, maternal shingles, which prompted the administration of VZ immunoglobulin to the newborn. The mother had no previous VZ vaccination. Eleven days later the baby developed a primary VZ infection, with only mild disease, likely as a result of the VZ immunoglobulin. The variable sensitivity of VZV IgG-specific assays is well-recognized. Thus, the ability of this particular VZV IgG assay to detect both maternal and infant VZV IgG, post-natally, suggests that the earlier VZV IgG negative results were due to lower circulating levels of maternal antibody.

Abstract
La survenue d'une varicelle clinique en cours de grossesse est rare, pouvant entrainer des risques maternels et fœtaux. La varicelle maternelle périnatale peut entrainer une varicelle néonatale potentiellement grave, notamment en cas d'éruptions maternelles survenant entre 5 jours avant et 2 jours après l'accouchement. Nous rapportons huit observations de nouveau-nés de mères ayant eu une varicelle en péri-partum dans le but de synthétiser, l'état actuel des connaissances sur le risque de ce virus et d'essayer d'élaborer un protocole de prise en charge. Il s'agit d'une étude descriptive menée au centre de maternité et de néonatologie de Sousse, sur une période de 10 ans. Huit nouveau-nés ont été inclus dans l'étude. Le diagnostic était fait avant l'accouchement chez 7 mères. Une seule femme avait développé sa varicelle 3 jours après l'accouchement. Cinq nouveau-nés étaient symptomatiques à l'admission. Ils avaient tous des lésions cutanées typiques de la varicelle, trois parmi eux avaient une atteinte respiratoire associée. La prise en charge était basée sur l'isolement des nouveau-nés, les soins locaux, et le traitement par Acyclovir. L'évolution était favorable dans tous les cas. La survenue d'une varicelle au cours de la grossesse reste possible dans les pays ou la vaccination n'est pas encore accessible à tous. Les risques de complications maternelles et fœtales qu'elle occasionne justifient une prise en charge spécifique et bien codifiée.

Abstract
In the United Kingdom, newborn assessment incorporates a screening eye examination for any structural abnormalities, observation of neonate's visual behaviour and direct ophthalmoscopy examination looking for red reflex. Early identification and immediate management of eye related pathologies should commence soon after birth as early diagnosis and prompt intervention may have significant impact on the prognosis for many potentially blinding but treatable disorders such as congenital cataracts and retinoblastoma. If left undetected and untreated, such problems may potentially lead to irreversible damage to the vision which persists into adulthood resulting in lack of self-confidence together with difficulties in educational attainment and job opportunities.

Abstract
Varicella-zoster virus, which is responsible for varicella (chickenpox) and herpes zoster (shingles), is ubiquitous and causes an acute infection among children, especially those aged less than six years. As 90% of adults have had varicella in childhood, it is unusual to encounter an infected pregnant woman but, if the disease does appear, it can lead to complications for both the mother and fetus or newborn. The major maternal complications include pneumonia, which can lead to death if not treated. If the virus passes to the fetus, congenital varicella syndrome, neonatal varicella (particularly serious if maternal rash appears in the days immediately before or after childbirth) or herpes zoster in the early years of life may occur depending on the time of infection. A Microbiology laboratory can help in the diagnosis and management of mother-child infection at four main times: (1) when a pregnant woman has been exposed to varicella or herpes zoster, a prompt search for specific antibodies can determine whether she is susceptible to, or protected against infection; (2) when a pregnant woman develops clinical symptoms consistent with varicella, the diagnosis is usually clinical, but a laboratory can be crucial if the symptoms are doubtful or otherwise unclear (atypical patterns in immunocompromised subjects, patients with post-vaccination varicella, or subjects who have received immunoglobulins), or if there is a need for a differential diagnosis between varicella and other types of dermatoses with vesicle formation; (3) when a prenatal diagnosis of uterine infection is required in order to detect cases of congenital varicella syndrome after the onset of varicella in the mother; and (4) when the baby is born and it is necessary to confirm a diagnosis of varicella (and its complications), make a differential diagnosis between varicella and other diseases with similar symptoms, or confirm a causal relationship between maternal varicella and malformations in a newborn.

Abstract
A wide array of infectious diseases can occur in pregnancy. Their acquisition, clinical presentation, and course during gestation may be altered due to an impairment of the maternal cellular immunity. Some infectious diseases can lead to serious consequences for the mother or the offspring, including congenital malformations. This review describes in detail the clinical presentation, course, management, and associated maternal and fetal risks of selected viral (varicella-zoster virus infections, condylomata acuminata), fungal (candida vulvovaginitis), bacterial (Lyme borreliosis), and parasitic (scabies) infections. The treatment options are critically reviewed. First-line therapies include acyclovir and varicella-zoster virus immunoglobulin for varicella-zoster virus infections, surgical modalities for genital warts, topical clotrimazole and oral fluconazole for Candida vulvovaginitis, amoxicillin and cefuroxime for Lyme borreliosis, and permethrin for scabies. A synopsis of maternal and fetal risks of other important infections is also included.

Abstract
Infection with varicella zoster virus (VZV) causes varicella (chickenpox), which can be severe in immunocompromised individuals, infants and adults. Primary infection is followed by latency in ganglionic neurons. During this period, no virus particles are produced and no obvious neuronal damage occurs. Reactivation of the virus leads to virus replication, which causes zoster (shingles) in tissues innervated by the involved neurons, inflammation and cell death - a process that can lead to persistent radicular pain (postherpetic neuralgia). The pathogenesis of postherpetic neuralgia is unknown and it is difficult to treat. Furthermore, other zoster complications can develop, including myelitis, cranial nerve palsies, meningitis, stroke (vasculopathy), retinitis, and gastroenterological infections such as ulcers, pancreatitis and hepatitis. VZV is the only human herpesvirus for which highly effective vaccines are available. After varicella or vaccination, both wild-type and vaccine-type VZV establish latency, and long-term immunity to varicella develops. However, immunity does not protect against reactivation. Thus, two vaccines are used: one to prevent varicella and one to prevent zoster. In this Primer we discuss the pathogenesis, diagnosis, treatment, and prevention of VZV infections, with an emphasis on the molecular events that regulate these diseases.

Abstract
Herpes simplex virus (HSV) hepatitis by definition constitutes disseminated herpes simplex infection; it is rare, with only approximately 130 cases reported in the literature. Although HSV hepatitis typically occurs in immunocompromised hosts, pregnancy—especially the third trimester, has been identified as a risk factor for its development. This is likely because of the fact that humoral and cell-mediated immunity decrease throughout pregnancy and nadir in the third trimester with decreased T-cell counts and altered B/T lymphocyte ratios. Here, we report on a patient with HSV 2 hepatitis in a previously healthy 27-year-old woman in her 23rd week of pregnancy. She initially presented with nausea, vomiting, and abdominal pain and was found to have acute hepatocellular liver injury and a systemic inflammatory response syndrome. Broad-spectrum antibiotics and acyclovir were promptly initiated. Liver biopsy, serum DNA polymerase chain reaction (PCR) as well as a labial ulcer culture and PCR were all positive for HSV 2. The patient recovered completely; however, her fetus did not survive. Review of the literature emphasizes that presentation with disseminated HSV infection typically occurs in the third trimester of pregnancy. This report emphasizes that abdominal pain combined with fever and hepatic dysfunction in pregnancy should prompt immediate consideration of the diagnosis of HSV hepatitis. Furthermore, given the high mortality rate and effective treatment, empiric treatment with acyclovir should be considered early in all potential cases.

Abstract
AIM Previous estimates of the incidence of varicella zoster virus (VZV) pneumonia and maternal death associated with VZV infection among the pregnant population have varied considerably and been based predominantly on reports from case series. We sought to measure the incidence of VZV-related morbidity and mortality to provide more representative population estimates. METHODS We carried out a large cohort study on all births using the United States Healthcare Cost and Utilization Project-Nationwide Inpatient Sample database between 2003 and 2010. Descriptive statistics were used to measure baseline characteristics and outcomes of women with VZV infection. Multivariate logistic regression analyses were used to identify risk factors for the development of VZV-related morbidity and mortality. RESULTS We identified 935 patients admitted for VZV infection among 7.7 million pregnancy admissions, representing an incidence of 1.21 cases/10 000 pregnancies (95% confidence interval [CI], 1.13-1.29). The incidence of VZV pneumonia was 2.5% (95% CI, 1.6-3.7). No maternal deaths were recorded during the 8-year study period. There were no significant risk factors identified for those who developed VZV pneumonia compared to those who had an uncomplicated VZV infection during pregnancy. CONCLUSION The incidence of VZV pneumonia and VZV infection associated with maternal death is significantly lower than previously estimated and may reflect better immunization and earlier interventions.

Abstract
BACKGROUND Congenital grouped skin lesions are alarming signs of a variety of threatening diagnoses of quite different origin. The present case report shows an impressive clinical pattern of a neonate and illustrates the difficulty in differential diagnosis of mixed connective tissue disease and neonatal lupus erythematosus in newborns. This reported case is to our knowledge the first description of an unrecognized mixed connective tissue disease in the mother with an unusual clinical manifestation in the newborn, comprising skin lesions, neurological damage and non-typical antibody constellation. CASE PRESENTATION We report on a Caucasian female neonate from a perinatally asymptomatic mother, who presented with grouped facial pustular-like skin lesions, followed by focal clonic seizures caused by multiple ischemic brain lesions. Herpes simplex virus infection was excluded and both the mother and her infant had the antibody pattern of systemic lupus erythematosus and neonatal lupus erythematosus, respectively. However, clinical signs in the mother showed overlapping features of mixed connective tissue disease. CONCLUSION This case report emphasizes congenital Lupus erythematosus and mixed connective tissue disease as important differential diagnoses of grouped skin lesions in addition to Herpes simplex virus-infection. The coexistence of different criteria for mixed connective tissue disease makes it difficult to allocate precisely maternal and congenital infantile disease.

Detection of herpes simplex and varicella-zoster virus in clinical specimens by multiplex real-time PCR and melting curve analysis. BIOMED RESEARCH INTERNATIONAL 2014; 2014:261947. [PMID: 24822189 PMCID: PMC4009197 DOI: 10.1155/2014/261947] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/09/2014] [Revised: 03/30/2014] [Accepted: 03/31/2014] [Indexed: 11/25/2022]
Abstract
Herpes simplex viruses types 1 and 2 (HSV-1 and HSV-2), and varicella-zoster virus (VZV) are common agents resulting in various forms of clinical manifestation from skin vesicle to disseminated viral infection. The aim of the present study was to develop a real-time PCR and melting curve analysis which detect and differentiate HSV-1, HSV-2, and VZV, to compare with PCR-RFLP using clinical specimens, and to introduce the 4-year experience in the clinical laboratory. Three pairs of primers for HSV-1, HSV-2, and VZV were designed. Primers for human endogenous retrovirus-3 (HERV-3), an internal control, were adopted. A hundred selected specimens and many clinical specimens were tested for methods comparison and assay validation. Increased sensitivity and specificity were obtained from real-time PCR. In review of results of clinical specimens submitted to clinical laboratory, a total of 46 of 3,513 specimens were positive in cerebrospinal fluids, blood, skin vesicles, genital swabs, aqueous humor, and ear discharge. Thus, this method could be a rapid and accurate alternative to virus culture and other molecular tests for detection and typing of HSV-1, HSV-2, and VZV.

Abstract
Varicella infection during pregnancy is associated with serious maternal and fetal complications such as congenital varicella syndrome, maternal pneumonia and neonatal varicella. Pregnant women are ineligible to receive the varicella vaccination, thus women who lack evidence of immunity to varicella are at an increased risk for developing a varicella infection if exposed to a contagious individual. Presently, post-exposure prophylaxis involves the administration of a varicella zoster immunoglobulin (VariZIG™) to prevent or reduce the severity of an infection. The US FDA recently approved VariZIG for licensure and recommend that it be administered as soon as possible following VZV exposure, ideally within 96 h for greatest effectiveness. The following review critically examines the role of VariZIG in post-exposure prophylaxis of varicella during pregnancy.

Abstract
Vesicles and pustules in the neonate can be due to common or life threatening conditions. Recognizing key clinical features and understanding when and how to workup the various different vesiculopustular eruptions that occur in the neonatal period is vital. A rapid diagnosis of an infectious cause of a neonatal vesiculopustular eruption can be life-saving.

Abstract
Commercial serologic assays for varicella-zoster virus (VZV), which enable reliable determination of VZV immune status and are amenable to automation, are needed. The present study compares the automated performance of the VZV whole-cell enzyme-linked immunosorbent assay (ELISA) Enzygnost anti-VZV/IgG, the Euroimmun anti-VZV ELISA (IgG) based on highly purified viral proteins, and the VZV glycoprotein (gp)-based Serion ELISA Classic VZV IgG. The fluorescent-antibody-to-membrane-antibody (FAMA) test was used as a reference. A total of 638 serum samples from VZV-negative children, blood donors, varicella vaccinees, and bone marrow transplant recipients were included. The Enzygnost anti-VZV/IgG and the Serion ELISA Classic VZV IgG showed sensitivities of 99.6% and 99.2%, respectively, and the Euroimmun anti-VZV ELISA (IgG) had a significantly lower sensitivity of 90.5%. Specificity was calculated as 100% for both the Euroimmun anti-VZV ELISA (IgG) and for the Enzygnost anti-VZV/IgG, and the Serion ELISA Classic VZV IgG had a significantly lower specificity of 89.4%. Quantitative results of all ELISAs correlated well, but there was a poor quantitative correlation between the ELISAs and FAMA. In conclusion, this study does not show any superiority of a gp- and a protein-based ELISA compared to a whole-cell ELISA for the automated detection of VZV-specific IgG. The automated performance of the Enzygnost anti-VZV/IgG assay correlated best with the FAMA reference assay.

Abstract
OBJECTIVE The purpose of this report is to present a case of herpes zoster in a 6-month-old infant, conservatively managed without oral antivirals, and its 13-year follow-up, demonstrating no sequelae or recurrences. CLINICAL FEATURES A 6-month-old white female infant presented with a vesicular rash of the right lower extremity to a chiropractic office. The rash consisted of grouped vesicles on erythematous plaques, the characteristic herpetiform lesion, distributed in the S1 dermatome of the right lower extremity only. The infant's history was significant for exposure to chicken pox at age 1 week through siblings. Consequently, only one vesicle developed, representing subclinical chicken pox. The clinical diagnosis of herpes zoster was made. INTERVENTION AND OUTCOME The infant was treated conservatively at home. Treatment consisted of aluminum acetate (Burow) solution compresses 3 times each day, followed by a loose dressing. The lesions crusted in 1 week and completely resolved in 2 weeks. Follow-up, consisting of 13 years of observation, demonstrated no evidence of sequelae, such as postherpetic neuralgia, or recurrence. CONCLUSION Herpes zoster is uncommon in infants; however, it may occur. The presentation of the rash is characteristic; but otherwise, the condition differs from that in adults in that it is mild and not associated with postherpetic neuralgia. In uncomplicated cases, conservative treatment measures support the quick resolution with no sequelae.

Abstract
BACKGROUND Varicella is predominantly a childhood disease, considered a mild self-limiting disease that can have serious complications for a pregnant woman and her developing fetus. OBJECTIVES We investigated the susceptibility to varicella-zoster Virus (VZV) among pregnant women in the province of Lecce. STUDY DESIGN A cross-sectional study was carried out in Departments of Gynecology and Obstetrics of the Province of Lecce, where 539 pregnant women were recruited, and face-to-face interviews were conducted. Varicella IgG tests were performed. RESULTS The prevalence of varicella susceptibility among pregnant mothers was 10.6%. The prevalence of IgG antibodies increases significantly with increasing age, from 62.5% in the age group 15-19 years to 94.4% in the age group 40-49 years. DISCUSSION In the Italian National Vaccination Plan 2005-2007, varicella vaccine is only recommended for childbearing women. A safe and effective vaccine is available and no abnormalities have been observed among infants born to susceptible women who received varicella vaccines during pregnancy. Such a high number of susceptible women indicates that preventive and informative programs should be introduced, even among those who do not plan to become pregnant. Routine counselling, varicella IgG antibody screening and varicella vaccination should be considered if they have no history of the infection, to reduce the risk of fetal complications and the cost of healthcare associated with the infection.

Abstract
Congenital varicella syndrome, maternal varicella-zoster virus pneumonia and neonatal varicella infection are associated with serious fetomaternal morbidity and, not infrequently, mortality. Vaccination against varicella-zoster virus can prevent the disease, and outbreak control limits the exposure of pregnant women to the infectious agent. Maternal varicella-zoster immunoglobulin administration before rash development, with or without antiviral medication, can modify the progression of the disease.

Abstract
Acyclovir resistance of varicella-zoster virus (VZV) has been reported in rare cases of immunocompromised patients. In this study, the natural polymorphism of the thymidine kinase (TK) and DNA polymerase (pol) genes was examined in 51 clinical VZV isolates sensitive to acyclovir (ACV). In addition, 16 VZV strains with clinical resistance to ACV were analyzed. None of the ACV-sensitive strains of the clades 1, 3 and 5 showed gene polymorphism of the TK. By contrast, the DNA pol gene exhibited polymorphism-related substitutions as a function of the VZV clade. The novel substitutions M286I, E824Q, R984H and H1089Y were detected in strains of clades 3 and 5. In the TK gene of 7 VZV strains with clinical ACV resistance, the novel substitutions L73I, A163stop, W225R, T256M, N334stop and the deletion of nucleotides 19-223 were found to be associated most likely with resistance. In one strain showing the substitution W225R, ACV resistance could be confirmed by the viral phenotype. In the DNA pol gene, the novel amino acid substitutions T237K and A955T could be detected, but their significance remains unclear. In conclusion, the characterization of resistance using genetic analysis of the TK and DNA pol genes has to be considered the method of choice for the determination of VZV resistance to antiviral drugs. In a considerable number of patients with clinical ACV-resistant VZV infections, resistance cannot be verified by virological methods.

Abstract
The article outlines examples of a viral (varicella-zoster virus, VZV), a bacterial (Lyme borreliosis) and a parasitic (scabies) infection in pregnancy with their risk for the mother and/or child as well as their management. VZV infections cause various clinical scenarios depending on the maternal immune status and the time of infection. Herpes zoster usually poses no risk to the pregnant woman and there is no need for antiviral therapy. VZV infection of a seronegative mother, however, may lead to severe varicella in the pregnant woman and to congenital malformations (congenital varicella syndrome) in case of early infection or neonatal varicella in case of perinatal infection. Prompt therapy with acyclovir or administration of VZV immunoglobulin for prophylaxis is mandatory in those patients. In case of Lyme borreliosis of the mother, adequate antibiotic therapy with amoxicillin prevents harm to the fetus. Doxycycline is contraindicated during pregnancy. Scabies represents an important differential diagnosis of pruritic dermatoses in pregnancy and should be treated with permethrin 5% cream.

Abstract
OBJECTIVE To describe the prevalence of congenital varicella syndrome (CVS) within the population of presumably infected pregnant women. METHODS From 1993 to 2006, all women who presented vesicular rash or a suspicious contact were referred and evaluated in a special unit at our center. Those with residual immunity or were serologically negative were precluded from this study. Positive IgM cases underwent monthly ultrasound scans (US), fetal blood (FB) sampling (including IgM anti VZV and virus culture). Amniotic fluid sample for PCR was added to the diagnosis of positive IgM cases after 1997. RESULTS A total of 276, of the 566 consulted women, tested positive for IgM anti VZV. Seventeen (6%) were excluded because of an unadvised termination of pregnancy and seven (2.55%) miscarried. Only seven (2.7%) were considered highly likely to have a VZV fetal infection. One case showed positive IgM in FB but developed normally. Another fetus showed positive PCR and infection was confirmed post TOP. Four cases that underwent TOP and histochemistry confirmed no more cases. Complete post-natal follow-up was carried out. The asymptomatic infected child grew healthy until the completion of screening tests when it reached 5 years old. CONCLUSION The fetal infection rate in this cohort was 0.8%, but the best expected prevalence of CVS, according to our findings, should be 0.39% among infected women. This data should be considered and used during parental counselling.

Abstract
A multicenter, open-label study evaluated the single-dose pharmacokinetics and safety of a pediatric oral famciclovir (prodrug of penciclovir) formulation in infants aged 1 to 12 months with suspicion or evidence of herpes simplex virus infection. Individualized single doses of famciclovir based on the infant's body weight ranged from 25 to 175 mg. Eighteen infants were enrolled (1 to <3 months old [n = 8], 3 to <6 months old [n = 5], and 6 to 12 months old [n = 5]). Seventeen infants were included in the pharmacokinetic analysis; one infant experienced immediate emesis and was excluded. Mean C(max) and AUC(0-6) values of penciclovir in infants <6 months of age were approximately 3- to 4-fold lower than those in the 6- to 12-month age group. Specifically, mean AUC(0-6) was 2.2 microg h/ml in infants aged 1 to <3 months, 3.2 microg h/ml in infants aged 3 to <6 months, and 8.8 microg h/ml in infants aged 6 to 12 months. These data suggested that the dose administered to infants <6 months was less than optimal. Eight (44.4%) infants experienced at least one adverse event with gastrointestinal events reported most commonly. An updated pharmacokinetic analysis was conducted, which incorporated the data in infants from the present study and previously published data on children 1 to 12 years of age. An eight-step dosing regimen was derived that targeted exposure in infants and children 6 months to 12 years of age to match the penciclovir AUC seen in adults after a 500-mg dose of famciclovir.

Abstract
Despite advances in peripartum care, maternal morbidity and mortality associated with infections in pregnancy are increasing even in developed countries. Recently published data from the Center for Disease Control's Pregnancy Mortality Surveillance System indicates that although maternal mortality from hemorrhage, embolism, and anesthesia has declined in the United States, the proportion of maternal deaths due to infections has increased. During 1991–7 infection accounted for 13.2% of pregnancy-related deaths overall and 36.3% of abortion-related deaths. The greatest infection risk is found in blacks, older women, women without prenatal care, and women with multiple pregnancy. In the United States pregnancy rates are stable or increasing in these groups. Infection is also a major cause of morbidity and mortality for the fetus and newborn. Many perinatal infections are associated with intra-uterine growth retardation and low birthweight, or cause fetal and neonatal brain injury. Infections, particularly bacterial vaginosis and chorioamnionitis, can result in preterm delivery of live-born infants (delivery before 37 weeks gestation), or stillbirth. A multitude of immunologic, endocrinologic, metabolic, physiologic, and anatomic changes influence the likelihood and course of many infections during pregnancy. Some of these changes are intrinsic, and occur in all normal pregnancies, while others occur to varying degrees in normal and abnormal pregnancies.

Abstract
Varicella (chickenpox) in pregnancy is unusual because most women of childbearing age are immune. It can, however, cause significant morbidity for the pregnant woman and in rare cases cause congenital varicella syndrome. The incidence of congenital varicella syndrome after maternal varicella during the first two trimesters is <1% across multiple cohort studies. Maternal infection in the third trimester is not associated with congenital varicella syndrome, but the infant may develop herpes zoster during the first one or two years. Maternal infection just before or after delivery presents a high risk for disseminated varicella in the infant. Serious infection can be prevented with passive antibody prophylaxis and antiviral therapy. Maternal herpes zoster does not result in adverse fetal or neonatal outcomes.

Abstract
Genital herpes is a chronic infection characterized by periodic reactivation. It can produce symptomatic disease in the host although asymptomatic viral excretion can also occur. It is currently the main cause of genital ulceration and an important public health problem that has substantial clinical, psychological, and economic repercussions. This review analyzes the currently available therapeutic options and regimens, which are based mainly on systemic use of antiviral agents such as aciclovir, valacyclovir, and famciclovir. In addition, special emphasis is placed on the prevention and management of this infection in specific situations, such as pregnant, pediatric, and immunocompromised patients.
