Acute and post-acute multidisciplinary outcomes of newborns born from mothers with SARS-CoV-2 infection during pregnancy or the perinatal period.

INTRODUCTION: We performed a single-center, prospective, observational study of newborns born from mothers with microbiologically confirmed SARS-CoV-2 infection in pregnancy or at time of delivery to evaluate acute and mid-term multidisciplinary outcomes. METHODS: Infants were offered a multidisciplinary follow-up consisting of nasopharyngeal Polymerase Chain Reaction test at birth and at 48-72 h of life, auxological and ophthalmological assessments, and serologic testing. RESULTS: 791 women and their 791 children (52.3% males) were included. Most placentas (94.9%) had abnormal inflammatory findings. 171 (27.3%) and 36 (13.7%) children respectively had pathological TEOAEs in at least one ear and bilaterally, while only four of the 85 children that underwent ABR had pathological findings (4.7%). 64 children underwent fluorescein angiography, which resulted pathological only in 1 case (1.6%). Anti-SARS-CoV-2 IgGs were found in up to 60% of children tested at six months of age. Our findings showed no association between the maternal vaccination status or the presence of maternal symptoms during pregnancy and neonatal outcomes. CONCLUSIONS: Our study shows that the large majority of newborns exposed to SARS-CoV-2 infection in utero or during the first hours of life have optimal outcomes. Our previous report of abnormal ophthalmologic findings was not confirmed on a larger cohort, while further studies are needed to better characterize audiological outcomes. Further prospective, case-controlled studies are still needed.

Short- and mid-term multidisciplinary outcomes of newborns exposed to SARS-CoV-2 in utero or during the perinatal period: preliminary findings.

The long-term outcomes of newborns exposed to SARS-CoV-2 infection in utero or during the first hours of life are still unknown. We performed a single-center, prospective, observational study of newborns born from mothers with microbiologically confirmed SARS-CoV-2 infection in pregnancy or at time of delivery. Infants were offered a multidisciplinary follow-up consisting of nasopharyngeal Polymerase Chain Reaction test at birth and at 48-72 h of life, auxological growth and neurological development, serologic testing, and audiological and ophthalmological assessments. One-hundred ninety-eight mothers and 199 newborns were enrolled. Of the 199 newborns, 171 underwent nasopharyngeal swab, four (2.3%) and two (1.15%) children tested positive at birth and 48-72 h of life, respectively. None had SARS-CoV-2 related symptoms. Auxologic and neurologic development were normal in all children during follow-up. Nine out of 59 infants had SARS-CoV-2 IgG at 3 months of life, which was associated with a positive nasopharyngeal swab at birth (P = 0.04). Twenty seven out of 143 (18.8%) newborns had pathologic transitory evoked otoacoustic emissions at birth, although 14/27 repeated after 1 month were normal. Audiological evaluation was completed with Auditory Brainstem Response between the third and sixth month of life in 34 children, showing in all normal hearing threshold. The ophthalmological evaluation found retinal vascular anomalies in 3/20 (15%) children, immature visual acuity in 5/20 (25%) children, and reduced distance attention in 6/20 cases (30%). CONCLUSIONS: Our study showed that the neonatal and mid-term multidisciplinary outcomes of newborns exposed to SARS-CoV-2 infection in utero or during the first hours of life are mostly positive, with the exception of ophthalmologic findings which, in a preliminary cohort, were abnormal in about 15% of cases. Further prospective, longitudinal studies are needed to better understand the clinical outcomes of children exposed to SARS-CoV-2 in utero and in the early postnatal life. WHAT IS KNOWN: • In utero mother-to-child transmission of SARS-CoV-2 has been documented by several independent studies. • Neonatal COVID-19 is a systemic disease that can be severe, although rarely. WHAT IS NEW: • Newborns exposed in utero to SARS-CoV-2 have mostly a normal auxological, audiological, and neurological development during the first months of life. • Fundus fluorescein angiography revealed that up to 5% of newborns exposed in utero to SARS-CoV2 can show retinal and choroidal abnormalities, including peripheral hypofluorescence of the choroid and increased vascular tortuosity.

Intestinal Parasitic Infections in Internationally Adopted Children: A 10-Year Retrospective Study.

BACKGROUND: Intestinal parasitic infections (IPIs) represent one of the leading causes of morbidity in the world. Children involved in international adoptions constitute a special group of subjects with specific problems and specific healthcare needs. Nevertheless, in current literature there are insufficient data on IPI in this subset of children. This study aims to evaluate the prevalence of IPI in a cohort of internationally adopted children and to investigate epidemiologic factors and clinical features related to IPIs. METHODS: A retrospective study involving internationally adopted children <18 years old for which results from 3 fecal parasitologic tests were available, evaluated between September 1, 2008 and April 31, 2018 at a tertiary level university hospital in Rome. Univariate and multivariate logistic regression analyses were carried out to identify demographic factors and clinical features associated with IPIs. Two comparisons were performed, the first one according to the positivity of the parasitologic examination of the feces and the second one according to the pathogenicity of the identified strains. RESULTS: Of 584 children evaluated, 346 (59.3%) had a positive parasitologic examination (143 pathogenic parasites and 203 nonpathogenic parasites) and 238 (40.8%) had a negative parasitologic examination. About 28.9% of children were positive for 2 or more parasites. A statistically significant positive association was found between IPIs and age, macroarea of origin (Africa and Latin America), living in institutions before adoption and vitamin D deficiency (P < 0.05). CONCLUSIONS: Intestinal parasites represent a widespread infection among internationally adopted children, especially in school-age children and those from Latin America and Africa. Importantly, the parasites found in adopted children were not pathogenic in most cases and did not cause significant alterations in growth, major micronutrient deficits or malnutrition.
