The role of point-of-care ultrasound in the management of neonates with congenital diaphragmatic hernia.

In the last few years, current evidence has supported the use of point-of-care ultrasound (POCUS) for a number of diagnostic and procedural applications. Considering the valuable information that POCUS can give, we propose a standardized protocol for the management of neonates with a congenital diaphragmatic hernia (CDH-POCUS protocol) in the neonatal intensive care unit. Indeed, POCUS could be a valid tool for the neonatologist through the evaluation of 1) cardiac function and pulmonary hypertension; 2) lung volumes, postoperative pleural effusion or pneumothorax; 3) splanchnic and renal perfusion, malrotations, and/or signs of necrotizing enterocolitis; 4) cerebral perfusion and eventual brain lesions that could contribute to neurodevelopmental impairment. In this article, we discuss the state-of-the-art in neonatal POCUS for which concerns congenital diaphragmatic hernia (CDH), and we provide suggestions to improve its use. IMPACT: This review shows how point-of-care ultrasound (POCUS) could be a valid tool for managing neonates with congenital diaphragmatic hernia (CDH) after birth. Our manuscript underscores the importance of standardized protocols in neonates with CDH. Beyond the well-known role of echocardiography, ultrasound of lungs, splanchnic organs, and brain can be useful. The use of POCUS should be encouraged to improve ventilation strategies, systemic perfusion, and enteral feeding, and to intercept any early signs related to future neurodevelopmental impairment.

Coagulation profiles and percentiles in neonates with hypoxic-ischemic encephalopathy undergoing therapeutic hypothermia: A step toward more accurate transfusion thresholds.

BACKGROUND: In the literature, there are no studies about the transfusion threshold for neonates with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH). In order to facilitate accurate interpretation of coagulation results in these neonates, we aimed to generate specific reference intervals in this specific population. METHODS: This retrospective study included all HIE neonates admitted from 2014 to 2022 to undergo TH. All infants during TH underwent blood exams, including the coagulation profile. Our primary outcome was to assess the estimates of the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles for each parameter on admission (before transfusion). By the receiver operating characteristic (ROC) analysis, the area under the ROC curve (AUC) and the best cut-off point were used to evaluate the ability of the prothrombin time expressed as international normalized ratio (PT-INR) to predict the risk of any bleeding. RESULTS: A total of 143 infants were included in this study. On admission, the median fibrinogen value was 205 mg/dL, prothrombin time 18.6 seconds, PT-INR 1.50, activated partial thromboplastin time 38.3 seconds, thrombin time 18.6 seconds, antithrombin 57.0%. The optimal cut-off of PT-INR in predicting the risk of any bleeding was greater than 1.84 (AUC .623, p = .024). CONCLUSION: For the first time, we proposed the percentiles of coagulation parameters in our cohort of neonates with HIE. Furthermore, we found that a PT-INR greater than 1.84 can significantly predict the risk of any bleeding. Further studies are needed to determine if a restrictive versus a liberal transfusion approach can be equally safer for these high-risk infants.

Perinatal asphyxia does not influence presepsin levels in neonates: A prospective study.

AIM: To compare Presepsin (presepsin) levels in plasma and urine of uninfected newborn infants with perinatal asphyxia with those of controls. METHODS: In this prospective study, we enrolled 25 uninfected full-term infants with perinatal asphyxia and 19 controls. We measured presepsin levels in whole blood or urine. In neonates with perinatal asphyxia, we compared presepsin levels in blood and urine at four time points. RESULTS: In neonates with perinatal asphyxia, blood and urinary presepsin levels matched each other at any time point. At admission, the median presepsin value in blood was similar in both groups (p = 0.74), while urinary levels were higher in hypoxic neonates (p = 0.05). Perinatal asphyxia seemed to increase serum CRP and procalcitonin levels beyond normal cut-off but not those of presepsin. CONCLUSION: In uninfected neonates with perinatal asphyxia, median blood and urinary presepsin levels matched each other at any point in the first 72 h of life and seemed to be slightly affected by the transient renal impairment associated with perinatal hypoxia in the first 12 h of life. Perinatal asphyxia did not influence presepsin levels within the first 72 h of life, while those of CRP and procalcitonin increased.

Neonatal herpes simplex virus infection: From the maternal infection to the child outcome.

This review examines the recent literature on the management of herpes simplex virus (HSV) infections in neonates. We summarized the three clinical categories of maternal HSV infection during pregnancy (primary first episode, nonprimary first episode, or recurrent episode) and the mechanisms of fetal damage. Considering when the transmission of the infection from the mother to the fetus/newborn occurs, three types of neonatal infection can be distinguished: intrauterine infection (5% of cases), postnatal infection (10% of cases), and perinatal infections (85% of cases). Neonatal presentation could range from a limited disease with skin, eye, and mouth disease to central nervous system disease or disseminated disease: the treatment with acyclovir should be tailored according to symptoms and signs of infection, and virological tests. These children need a multidisciplinary follow-up, to timely intercept any deviation from normal neurodevelopmental milestones. Prevention strategies remain a challenge, in the absence of an available vaccine against HSV.

Decreased incidence of late-onset sepsis during the SARS-CoV-2 pandemic in Italy: a multicentric study on a cohort of infants requiring major surgery.

Changes in the organization of the clinical care wards, requested by the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic, have influenced the environmental circulation of other pathogens. The implementation of prevention procedures may have led to a decrease in the incidence of healthcare-associated infections. We aimed to investigate the impact of prevention and control measures for preventing the COVID-19 spread on the incidence of bacterial sepsis and invasive fungal infections in neonates and infants requiring major surgery. We compared the incidence of bacterial and fungal sepsis and their risk factors observed before the SARS-CoV-2 pandemic (from 01/10/2018 to 29/02/2020) with those observed during the pandemic (from 01/03/2020 to 07/05/2021) in 13 level III Neonatal Intensive Care Units in Italy, through a secondary analysis of data, collected during a prospective multicenter study (REF). The patients enrolled were infants within three months of life, hospitalized in the two periods in the participating centers to undergo major surgery. Among 541 enrolled patients, 324 (59.9%) were born in the pre-pandemic period and 217 (40.1%) during the pandemic. The incidence density (ID) of any infection in the pre-pandemic period was 16.0/1000 patient days versus 13.6/1000 patient days in the pandemic period (p < 0.001). One hundred and forty-five (145/324; 44.8%) patients developed at least one episode of bacterial sepsis in the pre-pandemic period, versus 103/217 (31.8%) patients, during the pandemic (p = 0.539). Concerning fungal sepsis, 12 (3.7%) patients had one episode in the pre-pandemic period versus 11 (5.1%) patients during the pandemic (p = 0.516). The most significant differences observed in the use of healthcare procedures were the reduction of CVC days, the reduced use of antibiotics pre-surgery, and that of proton pump inhibitors during the SARS-CoV-2 pandemic compared with the previous period. CONCLUSIONS: In our cohort of patients with major surgical needs, the reduction of CVC days, pre-surgery antibiotics administration, and current use of proton pump inhibitors, during the SARS-CoV-2 pandemic, led to a decrease in the incidence of late-onset sepsis. WHAT IS KNOWN: • Most cases of late-onset sepsis in neonates are referred to as central line-associated bloodstream infections. • In adults, the COVID-19 outbreak negatively influenced healthcare-associated infection rates and infection clusters within hospitals. WHAT IS NEW: • In neonates and infants undergoing major surgery the incidence density of infections was lower in the pandemic period than before. • The most significant differences observed in the use of healthcare procedures were the reduction of CVC days, the reduced use of antibiotics before surgery, and that of proton pump inhibitors during the pandemic compared with previously.

The Emerging Role of Presepsin (P-SEP) in the Diagnosis of Sepsis in the Critically Ill Infant: A Literature Review.

Sepsis causes high rates of morbidity and mortality in NICUs. The estimated incidence varies between 5 and 170 per 1000 births, depending on the social context. In very low birth-weight neonates, the level of mortality increases with the duration of hospitalization, reaching 36% among infants aged 8-14 days and 52% among infants aged 15-28 days. Early diagnosis is the only tool to improve the poor prognosis of neonatal sepsis. Blood culture, the gold standard for diagnosis, is time-consuming and poorly sensitive. C-reactive protein and procalcitonin, currently used as sepsis biomarkers, are influenced by several maternal and fetal pro-inflammatory conditions in the perinatal age. Presepsin is the N-terminal fragment of soluble CD14 subtype (sCD14-ST): it is released in the bloodstream by monocytes and macrophages, in response to bacterial invasion. Presepsin seems to be a new, promising biomarker for the early diagnosis of sepsis in neonates as it is not modified by perinatal confounding inflammatory factors. The aim of the present review is to collect current knowledge about the role of presepsin in critically ill neonates.

Neonatal Encephalopathy and SIADH during RSV Infection.

OBJECTIVE: This report discusses the neurological involvement in respiratory syncytial virus (RSV) infection in neonates. STUDY DESIGN: We present a case report of a 2-month-old infant affected by a bronchiolitis RSV-positive, with syndrome of inappropriate antidiuretic hormone secretion (SIADH) correlated seizure and encephalopathy. RESULTS: RSV infection can be associated as a serious disease in newborns involving the central nervous system (CNS) and causing seizures or acute encephalopathy. RSV may be also responsible for SIADH and seizures associated with hyponatremia. The RSV related encephalopathy could be caused by different mechanisms, such as direct viral invasion of the CNS or by indirect mechanism mediated by inflammatory cytokines. In addition, it can be favored by severe hyponatremia and SIADH that can cause cerebral edema. Some studies highlight that this virus-related encephalopathy lead to sudden infant death syndrome. CONCLUSION: In presence of neurological involvement during RSV-infection must be taken in consideration to performing instrumental test to detect cerebral edema. In addiction could be useful to dose inflammatory cytokines, and to consider the immune-modulatory therapy.

Diagnosis and Management of Neonatal Bacterial Sepsis: Current Challenges and Future Perspectives.

Sepsis remains the second cause of death among neonates after the pathological consequences of extreme prematurity. In this review we summarized knowledge about pathogens causing early-onset sepsis (EOS) and late-onset sepsis (LOS), the role of perinatal risk factors in determining the EOS risk, and the tools used to reduce unnecessary antibiotics. New molecular assays could improve the accuracy of standard blood cultures, providing the opportunity for a quick and sensitive tool. Different sepsis criteria and biomarkers are available to date, but further research is needed to guide the use of antibiotics according to these tools. Beyond the historical antibiotic regimens in EOS and LOS episodes, antibiotics should be based on the local flora and promptly modulated if specific pathogens are identified. The possibility of an antibiotic lock therapy for central venous catheters should be further investigated. In the near future, artificial intelligence could help us to personalize treatments and reduce the increasing trend of multidrug-resistant bacteria.

Stop in Time: How to Reduce Unnecessary Antibiotics in Newborns with Late-Onset Sepsis in Neonatal Intensive Care.

The fear of missing sepsis episodes in neonates frequently leads to indiscriminate use of antibiotics, and prescription program optimization is suggested for reducing this inappropriate usage. While different authors have studied how to reduce antibiotic overprescription in the case of early onset sepsis episodes, with different approaches being available, less is known about late-onset sepsis episodes. Biomarkers (such as C-reactive protein, procalcitonin, interleukin-6 and 8, and presepsin) can play a crucial role in the prompt diagnosis of late-onset sepsis, but their role in antimicrobial stewardship should be further studied, given that different factors can influence their levels and newborns can be subjected to prolonged therapy if their levels are expected to return to zero. To date, procalcitonin has the best evidence of performance in this sense, as extrapolated from research on early onset cases, but more studies and protocols for biomarker-guided antibiotic stewardship are needed. Blood cultures (BCs) are considered the gold standard for the diagnosis of sepsis: positive BC rates in neonatal sepsis workups have been reported as low, implying that the majority of treated neonates may receive unneeded drugs. New identification methods can increase the accuracy of BCs and guide antibiotic de-escalation. To date, after 36-48 h, if BCs are negative and the baby is clinically stable, antibiotics should be stopped. In this narrative review, we provide a summary of current knowledge on the optimum approach to reduce antibiotic pressure in late-onset sepsis in neonates.

Use of N-Acetylcysteine in Preterm Neonates with Enteral Feeding Intolerance and Intestinal Obstruction: A Case Series and Review of the Literature.

(1) Background: The use of N-acetylcysteine (NAC) to relieve meconium obstruction of prematurity in the first days of life has been reported, with NAC reducing the viscosity of luminal contents by cleaving the disulfide bonds of mucoproteins. However, its use in this population should be further explored since it has been associated with hypernatremia and transient increase in transaminases and bilirubin. (2) Methods: In this retrospective study, we included neonates admitted because of enteral feeding intolerance and intestinal obstruction from 2019 to 2021 who received NAC as a rescue therapy before explorative laparotomy. (3) Results: We summarized the clinical presentation of six preterm neonates with enteral feeding intolerance and intestinal obstruction who received NAC as a rescue therapy. Four infants (66.7%) gradually improved without the need for explorative laparotomy, whereas two infants (33.3%) underwent the creation of an ileostomy. No cases of hypernatremia or hepatic derangement associated with NAC therapy were observed. (4) Conclusions: We described the use of NAC treatment by nasogastric tube and/or rectal enemas in preterm infants with enteral feeding intolerance and intestinal obstruction after a multidisciplinary assessment, but the limited sample size did not allow us to obtain definitive conclusions and further research is needed in this field, given the limited evidence about NAC treatment in preterm infants.

A new variant in the GATA6 gene associated with tracheoesophageal fistula, pulmonary vein stenosis and neonatal diabetes.

INTRODUCTION: GATA6 is a gene that encodes a transcription factor with a key role in the development of several organ systems, including the development of the pancreas. It is associated with neonatal diabetes but also with other extra-pancreatic anomalies. CASE PRESENTATION: This report describes the association of tracheoesophageal fistula (TEF), pulmonary vein stenosis (PVS), and neonatal diabetes caused by a novel mutation of the GATA6 gene in a small-for-gestational-age male neonate born at 32 weeks of gestation. Next-Generation Sequencing revealed the novel heterozygous variant c.1502C>G in the GATA6 gene, which determines the introduction of the premature stop codon p.Ser501Ter at the protein level. This de novo nonsense variant was not detected in the analyzed parental DNA samples and has not been previously described in the literature. At about two months of life, a PVS was suspected. The PVS progressively increased with the development of an intramural component, resulting in severe postcapillary pulmonary hypertension. The child died at about 4 months of life. CONCLUSION: TEF can be associated with GATA6 variants. In the case of neonatal diabetes and TEF, neonatologists should be aware of this association and should also investigate the child for complex congenital heart disorders, such as in our case, with a cardiac computed tomography.

Comparison of three clinical scoring tools for bronchiolitis to predict the need for respiratory support and length of stay in neonates and infants up to three months of age.

Background: Bronchiolitis severity can be assessed using different clinical scores. Some of the most used are the Wang Bronchiolitis Severity Score (WBSS), the Kristjansson Respiratory Score (KRS), and the Global Respiratory Severity Score (GRSS), calculated on the vital parameters and the clinical conditions. Objective: To assess which of the three clinical scores better predicts the need for respiratory support and length of hospital stay in neonates and infants younger than three months, admitted to neonatal units for bronchiolitis. Methods: Neonates and infants younger than three months admitted to neonatal units from October 2021 to March 2022 were included in this retrospective study. The scores were calculated in all patients soon after admission. Results: Ninety-six patients (of whom 61 neonates) admitted for bronchiolitis were included in the analysis. Median WBSS at admission was 4.00 (interquartile range, IQR 3.00-6.00), median KRS was 4.00 (IQR 3.00-5.00), and median GRSS 4.90 (IQR 3.89-6.10). We found significant differences in all three scores between infants who needed respiratory support (72.9%) and those who did not (27.1%) (p < 0.001). A value >3 for WBSS, > 3 for KRS, and >3.8 for GRSS were accurate in predicting the need for respiratory support, with a sensitivity of 85.71%, 75.71%, and 93.75% and a specificity of 80.77%, 92.31%, and 88.24%, respectively. The three infants who required mechanical ventilation had a median WBSS of 6.00 (IQR 5.00-6.50), a KRS of 7.00 (IQR 5.00-7.00), and a GRSS of 7.38 (IQR 5.59-7.39). The median length of stay was 5 days (IQR 4-8). All three scores were significantly correlated with the length of stay, although with a low correlation coefficient: WBSS with an r2 of 0.139 (p < 0.001), KRS with an r2 of 0.137 (p < 0.001), and GRSS with an r2 of 0.170 (p < 0.001). Conclusion: Clinical scores WBSS, KRS, and GRSS calculated on admission accurately predict the need for respiratory support and the length of hospital stay in neonates and infants younger than three months with bronchiolitis. The GRSS score seems to better discriminate the need for respiratory support than the others.

Lung Ultrasound Score in Neonates with Congenital Diaphragmatic Hernia (CDH-LUS): A Cross-Sectional Study.

Introduction: The use of a lung ultrasound (LUS) score has been described in the early phases of neonatal respiratory distress syndrome; however, there is still no data regarding the application of the LUS score to neonates with a congenital diaphragmatic hernia (CDH). The objective of this observational cross-sectional study was to explore, for the first time, the postnatal changes in LUS score patterns in neonates with CDH, with the creation of a new specific CDH-LUS score. Methods: We included all consecutive neonates with a prenatal diagnosis of CDH admitted to our Neonatal Intensive Care Unit (NICU) from June 2022 to December 2022 who underwent lung ultrasonography. Lung ultrasonography (LUS) was determined at scheduled time points: (T0) during the first 24 h of life; (T1) at 24-48 h of life; (T2) within 12 h of surgical repair; (T3) a week after the surgical repair. We used a modified LUS score (CDH-LUS), starting from the original 0-3 score. We assigned 4 as a score in the presence of herniated viscera in the hemithorax (liver, small bowel, stomach, or heart in the case of a mediastinal shift) in the preoperative scans or pleural effusions in the postoperative scans. Results: We included in this observational cross-sectional study 13 infants: twelve/13 had a left-sided hernia (2 severe, 3 moderate, and 7 mild cases), while one patient had a right-sided severe hernia. The median CDH-LUS score was 22 (IQR 16-28) during the first 24 h of life (T0), 21 (IQR 15-22) at 24-48 h of life (T1), 14 (IQR 12-18) within 12 h of surgical repair (T2) and 4 (IQR 2-15) a week after the surgical repair (T3). The CDH-LUS significantly dropped over time from the first 24 h of life (T0) to a week after the surgical repair (T3), according to ANOVA for repeated measures. Conclusion: We showed a significant improvement in CDH-LUS scores from the immediate postoperative period, with normal ultrasonographic evaluations a week after surgery in most patients.

Staphylococcal Infections and Neonatal Skin: Data from Literature and Suggestions for the Clinical Management from Four Challenging Patients.

Staphylococcal infections in neonates might be associated with skin blistering since early antibiotic therapy has been shown to limit infection spread and positively influence outcomes; therefore, neonatologists should be aware of these conditions. This review examines the recent literature on the management of Staphylococcal infections that involve neonatal skin, discussing the most appropriate clinical approach to four cases of neonatal blistering diseases with Staphylococcal infections: a case of Staphylococcal bullous impetigo, a case of Staphylococcal scalded skin syndrome (SSSS), a case of epidermolysis bullosa with overlapping Staphylococcal infection, and a case of burns with overlapping Staphylococcal infection. In treating Staphylococcal infections involving skin in neonates, the presence or absence of systemic symptoms should be considered. In the lack of evidence-based guidelines in this age category, treatment should be individualized according to several factors including the extension of the disease or further skin comorbidities (such as skin fragility), with a multidisciplinary approach.

Use of levosimendan in hemodynamic management of heart failure in two neonates with intracranial arteriovenous shunts: a case series.

BACKGROUND: The hemodynamic status of newborns with intracranial arteriovenous shunts (AVSs) may be extremely complex. Mini-invasive hemodynamic monitoring through innovative techniques such as Near-Infrared Spectroscopy (NIRS) and Pressure Recording Analytical Method (PRAM) may help in understanding hemodynamics in newborns with AVSs. Levosimendan is a calcium sensitizer and inodilator, and it is known to improve ventricular function, but its use in newborns is limited. In our cases, we evaluated the effect of levosimendan on hemodynamics through NIRS and PRAM. CASE PRESENTATION: Herein, we report the cases of two neonates with intracranial arteriovenous shunts, in whom we used levosimendan to manage cardiac failure refractory to conventional treatment. Levosimendan was used at a dosage of 0.1 mcg/kg/min for 72 h. Combined use of NIRS and PRAM helped in real-time monitoring of hemodynamic effects; in particular, levosimendan determined significant improvement in myocardium contractility as well as a reduction of heart rate. CONCLUSION: In two neonatal cases of AVSs, levosimendan led to an overall hemodynamic stabilization, documented by the combination of NIRS and PRAM. Our results suggest introducing levosimendan as a second-line treatment in cases of severe cardiac dysfunction due to AVSs without improvement using standard treatment strategies. Future prospective and larger studies are highly warranted.

Are lung ultrasound features more severe in infants with bronchiolitis and coinfections?

Background: The lung ultrasound (LUS) score can be a useful tool to predict the need for respiratory support and the length of hospital stay in infants with bronchiolitis. Objective: To compare lung ultrasound features in neonates and infants up to three months of age with bronchiolitis to determine whether LUS scores (range 0-36) differ in infants with coinfections or not. Methods: Neonates and infants younger than three months admitted to neonatal units from October 2022 to March 2023, who underwent lung ultrasound evaluation on admission, were included in this retrospective study. Results: We included 60 patients who underwent LUS evaluation at admission. Forty-two infants (70.0%) had a single viral infection. Eighteen infants (30.0%) had a coinfection: fifteen infants (25.0%) had more than one virus at PCR; one infant (1.7%) had both a viral coinfection and a viral-bacteria coinfection; two infants (3.3%) had viral-bacteria coinfection. Infants with a single viral infection and those with coinfections had similar LUS scores globally and in different lung zones. An LUS score higher than 8 was identified to significantly predict the need for any respiratory support (p = 0.0035), whereas an LUS score higher than 13 was identified to significantly predict the need for mechanical ventilation (p = 0.024). Conclusion: In our small cohort of neonates and infants younger than three months hospitalized with bronchiolitis, we found no statistically significant differences in the LUS score on admission between patients with a single viral infection and those with multiple infections.

Multisystem Inflammatory Syndrome in Neonates Born to Mothers with SARS-CoV-2 Infection (MIS-N) and in Neonates and Infants Younger Than 6 Months with Acquired COVID-19 (MIS-C): A Systematic Review.

(1) Introduction: There is an increasing literature describing neonates born to mothers with SARS-CoV-2 infection (MIS-N) and infants infected with SARS-CoV-2 who presented with a severe disease (MIS-C). (2) Methods: To investigate clinical features of multisystem inflammatory syndrome in neonates and infants under six months of age, we used a systematic search to retrieve all relevant publications in the field. We screened in PubMed, EMBASE and Scopus for data published until 10 October 2021. (3) Results: Forty-eight articles were considered, including 29 case reports, six case series and 13 cohort studies. Regarding clinical features, only 18.2% of MIS-N neonates presented with fever; differently from older children with MIS-C, in which gastrointestinal symptoms were the most common manifestation, we displayed that cardiovascular dysfunction and respiratory distress are the prevalent findings both in neonates with MIS-N and in neonates/infants with MIS-C. (4) Conclusions: We suggest that all infants with suspected inflammatory disease should undergo echocardiography, due to the possibility of myocardial dysfunction and damage to the coronary arteries observed both in neonates with MIS-N and in neonates/infants with MIS-C. Moreover, we also summarize how they were treated and provide a therapeutic algorithm to suggest best management of these fragile infants.

Maternal-Fetal Infections (Cytomegalovirus, Toxoplasma, Syphilis): Short-Term and Long-Term Neurodevelopmental Outcomes in Children Infected and Uninfected at Birth.

(1) Background: Infections in pregnancy can lead to miscarriage, premature birth, infections in newborns, and developmental disabilities in babies. Infected infants, symptomatic at birth, can have long-term sequelae, and asymptomatic babies are also at increased risk of developing long-term sensorineural outcomes. Targeted therapy of the pregnant mother can reduce fetal and neonatal harm. (2) Aim of the study: To explore the association between symptoms and time of onset of long-term sequelae in infected children born from mothers who contracted an infection during pregnancy, by a long-term multidisciplinary follow-up. (3) Methods: For up to 2−4 years, we evaluated cognitive, motor, audiological, visual, and language outcomes in infants with symptomatic and asymptomatic congenital infections and in uninfected infants. (4) Results: 186 infants born from women who acquired Cytomegalovirus infection (n = 103), Toxoplasma infection (n = 50), and Syphilis (n = 33) during pregnancy were observed. Among them, 119 infants acquired the infection in utero. Infected infants, symptomatic at birth, obtained lower scores on the Cognitive and Motor Scale on Bayley-III compared to asymptomatic and uninfected infants (p = 0.026; p = 0.049). Many severe or moderate sequelae rose up within the first year of life. At 24 months, we observed sequelae in 24.6% (14/57) of infected children classified as asymptomatic at birth, compared to 68.6% (24/35) of symptomatic ones (χ2 = 15.56; p < 0.001); (5) Conclusions: Infected babies symptomatic at birth have a worse prognosis than asymptomatic ones. Long-term sequelae may occur in infected children asymptomatic at birth after the first year of life. Multidisciplinary follow-up until 4−6 years of age should be performed in all infected children, regardless of the presence of symptoms at birth.

Clinical and Neurodevelopmental Characteristics of Enterovirus and Parechovirus Meningitis in Neonates.

Background: Non-polio-enteroviruses (EV) and human parechoviruses (HPeV) are small RNA viruses, which in newborns cause infections with a wide range of severity. Today molecular biology tools allow us to diagnose viral meningitis in neonates, sparing patients from useless antibiotics. Data on neurodevelopmental outcome of children who contract enterovirus meningitis in early childhood are still limited in the literature. Aims: To evaluate the neurodevelopmental outcome of newborns with documented enterovirus and parechovirus meningitis contracted within the first months of life. Methods: Enterovirus and parechovirus were detected on cerebrospinal fluid (CSF) and plasma by RT-PCR. The virological typing was done according to WHO recommendations. During the hospitalization each neonate underwent many diagnostic and instrumental examinations, to evaluate any neurological lesions attributable to the infection. After the discharge children entered in an outpatient interdisciplinary assessment process, comprehensive of the administration of Bayley III scales up to 12 months old. Results: We observed longitudinally 30 children, born at term (mean GA 39.7 ± 0.8 weeks, mean birthweight was 3,457 ± 405 grams), who contracted enterovirus and parechovirus meningitis within the first month of life (mean age at diagnosis was 15.8 ± 7.33 days). We were able to perform the genetic typing only on 15/30 (50.0%) cerebrospinal fluid (CSF) samples from 15 neonates. We found MRI anomalies in 9/26 observed neonates (34.6%): one of them presented brainstem abnormality that are specific of enteroviral central nervous system (CNS) involvement. During the follow up children displayed an overall normal neurodevelopment and no deficit in visual and hearing areas. The mean cognitive (105.19 ± 8.71), speech (100.23 ± 8.22) and motor (97.00 ± 8.98) composite scores, assessed by Bayley III, were normal in 29/30 (96.7%). Despite this, children with pathological brain magnetic resonance imaging (MRI) scored significantly lower (p = 0.01) than children with normal brain MRI on cognitive subscale at 12 months of life. Conclusions: Early enterovirus infections can be associated to brain MRI abnormalities, more frequently the earlier the infection. Although within a normal range, our children with pathological brain MRI scored significantly lower than those with normal brain MRI on cognitive subscale at 12 months of life.
