RESUMO

The resurgence of syphilis and subsequent risk for newborns has been described worldwide; however, European data on this congenital infection is lacking. We report the activity of a multidisciplinary specialized unit assisting a large area in the Southern Italy. A retrospective cohort study has been conducted at the Perinatal and Pediatric Infectious Diseases Units of the Federico II University of Naples, enrolling all newborns and children referred from January 2010 to June 2022 exposed to Treponema pallidum in utero and/or congenitally infected. A total of 323 patients were included in the analysis. Twenty (6.2%) received a diagnosis of confirmed congenital syphilis (CS) and one died. Fifteen CS cases had typical clinical features. Since 2017, the number of referred neonates tripled while the rate of late maternal diagnoses did not significantly differ. When compared with mothers of exposed infants, mothers of CS cases were younger (25 ± 7.2 vs 29.9 ± 6 years, p = 0.041), had less previous pregnancies (0.64 vs 1.11, p = 0.044), and received a diagnosis of syphilis at a later stage of pregnancy (86% vs 20%, from third trimester or later on; p < 0.001). Appropriate maternal therapy was protective against vertical transmission (- 1.2; - 1.4, - 1 95% CI; p < 0.001). Paternal syphilis status was known in 36% of cases. CONCLUSION: CS has still a significant impact. Prevention should be implemented towards specific maternal risk profiles. A specialized unit is the preferable model to improve surveillance and healthcare for this neglected population. WHAT IS KNOWN: • The resurgence of syphilis and subsequent risk for newborns has been described worldwide. • European data on this congenital infection is lacking. WHAT IS NEW: • Congenital syphilis has a significant impact still in Europe and prevention should be implemented towards specific maternal risk profiles.  • A specialized unit is the preferable model to improve surveillance and healthcare for this neglected population.

RESUMO

Background: Congenital cytomegalovirus (cCMV) infection is a frequent cause of neurosensory impairment. Ocular abnormalities and visual impairment have been reported in a high percentage of symptomatic infants, whereas they are considered uncommon in asymptomatic ones. The paucity of data has made difficult to reach clear recommendations on the ophthalmological follow-up that should be provided. Methods: 250 patients with cCMV infection (123 symptomatic) were enrolled and underwent a series of age-appropriate ophthalmologic, audiologic, and neurodevelopmental examinations from 2002 to 2022. Results: Funduscopic abnormalities were identified at onset in 16/123 (13%) symptomatic infants and in none of the asymptomatic ones (p < 0.001). Chorioretinitis lesions were the most common findings (10/16 cases), while the others showed retinal scars. Lesions were bilateral in 4 patients. No later onset retinal lesions were detected, nor in symptomatic or in asymptomatic children. Five of the 16 (31.5%) symptomatic and none of the asymptomatic subjects showed visual impairment al the last evaluation (p < 0.001). All patients with unfavorable outcome had also neurological impairment. Among symptomatic patients, ocular lesions were associated with central nervous system (CNS) pathological findings in prenatal ultrasonography (p 0.05) and with clinical signs of CNS involvement at birth (p 0.046). No correlation was found with the type of maternal infection and pathological neuroimaging. Conclusions: Chorioretinal lesions are a fairly common finding at birth in neonates with symptomatic cCMV, often associated with long term visual impairment. Asymptomatic infants do not show ophthalmological abnormalities in the short or long term. This information is relevant both to parental counseling and to cost-effective patient management.

RESUMO

BACKGROUND: For infants exposed in utero to Toxoplasma gondii, current guidelines recommend monitoring the specific antibody titer until 12 months of age. In this study, we investigated the antibody titer decay in the mother-infant dyad. METHODS: This is a single center, population-based cohort study of neonates referred for prenatal exposure to Toxoplasma gondii from January 2014 to December 2020. All infants underwent clinical, laboratory, and instrumental investigation for at least 12 months. RESULTS: A total of 670 eligible neonates were referred to the Perinatal Infection Unit of the University Federico II of Naples. 636 (95%) completed the serological follow up until 12 months. Specific IgG antibodies negativization occurred in 628 (98.7%) within 5 months. At 9 and 12 months, all patients had negative IgG. An initial neonatal IgG antibody titer ≥ 200 IU/ml was associated with a longer time to negativization (184 [177.5;256] days when above threshold vs. 139.5 [101;179] days when below it; p < 0.001). Maternal IgG antibody titer ≥ 200 IU/ml at childbirth was also associated to delayed time to negativization in the infant (179 [163;184] days above the threshold vs 125 [96.8;178] days below it; p < 0.001). Specific antibody negativization was irreversible in all patients. CONCLUSIONS: Lower anti-Toxoplasma antibody titers detected at birth in the mother-infant-dyad lead to an earlier and irreversible negativization. This information allows for customisation of the infant follow up program and avoids invasive and expensive tests.

RESUMO

Background and Aim: Cytomegalovirus (CMV) is the main cause of congenital infection in developed countries leading to deafness but the burden of sensorineural hearing loss (SNHL) in asymptomatic children remains incompletely characterized. Aim of this study was to evaluate the long-term audiological outcome in this group of patients. Methods: Consecutive neonates with congenital CMV infection were followed from 2002 to 2018. Patients were considered asymptomatic if free from any clinical and instrumental impairment at referral and underwent serial clinical exams, audiological evaluations and CMV-PCR determinations. Results: A cohort of 258 children was analyzed and the disease onset was asymptomatic in 125 (48%) infants. Among these, we studied 102 patients with a follow-up longer than 1 year and a median observation period of 2.8 years (range: 1-10.3 years). No patient developed a stable delayed SNHL but only 14 (14%) presented a variable hearing impairment, seven of which bilateral. The unstable SNHL was mild in 12 infants and moderate in two. Patients with fluctuating SNHL had significantly higher urine viral load (p 0.002) and more often positive viremia (p 0.015) than babies with stable normal hearing. Conclusions: CMV infected, asymptomatic neonates have a low risk of transient SNHL later in infancy. Positive viremia and high urine viral load at onset are significant risk factors for delayed fluctuating SNHL. These data are relevant for an appropriate follow up plan of these patients.

RESUMO

BACKGROUND: The accurate stratification of infants with congenital cytomegalovirus (CMV) infection at risk for more severe outcome may help in the management of patients. Aim of this study was to investigate the ability of a comprehensive neuroimaging investigation in predicting the long-term neurodevelopmental outcome in patients with congenital CMV. We analyzed the prognostic accuracy of a traditional score and a recently proposed scale applied to head ultrasound (HUS), computed tomography (CT) and magnetic resonance imaging (MRI). METHODS: All consecutive neonates born from 2002 to 2015 with congenital CMV infection were considered eligible for the study. Neuroimaging findings were scored according to both scores. RESULTS: One hundred seventy infants were included (112 symptomatic patients). One-hundred eighteen infants received both HUS, CT and MRI. CT and MRI were normal in all 56 asymptomatic patients, while 32% of them presented an abnormal HUS. The prevalence of abnormal findings differed according to the neuroimaging study. The sensitivity of the new neuroimaging score in detecting patients at risk for poor neurologic outcome was higher than the traditional one for all neuroimaging examinations. CT and MRI showed higher positive predictive value compared with HUS. No neuroimaging examination showed a negative predictive value equal to 100%. CONCLUSIONS: Although HUS is the safest neuroimaging technique, it performs less well in detecting some brain abnormalities that can be associated with a poor neurodevelopmental outcome. A comprehensive neuroimaging evaluation is mandatory in infants with congenital CMV infection to decide for treatment and make a prognostic evaluation.

RESUMO

BACKGROUND: Lenticulostriated vasculopathy (LSV) detected in head ultrasound (HUS) has been related to neurological and hearing sequelae in infants with congenital cytomegalovirus (cCMV) infection. OBJECTIVE: To assess the role of LSV in predicting neurodevelopmental and hearing outcomes in infants with cCMV infection. STUDY DESIGN: We enrolled consecutive infants who were affected by cCMV infection and underwent HUS within the first month of life. Data on clinical onset and course, laboratory findings, visual/hearing functions and neurodevelopmental outcome were collected. As controls, infants with suspected intrauterine exposure to Toxoplasma and with no confirmed congenital toxoplasmosis were considered. RESULTS: Data from 161 infants with cCMV infection (105 symptomatic) and 133 controls were analyzed. HUS was normal in 66 (41%) cCMV patients. Among these, 28 (42.4%) were symptomatic and 38 (57.6%) asymptomatic infants. The percentage of patients with no HUS abnormalities was higher in asymptomatic (38/56, 67.9%) than in symptomatic infants (28/105, 26.7%) (p<0.05). LSV, as isolated or associated with other brain abnormalities, was diagnosed in 64/161 (39.7%) patients with cCMV compared to 24/133 (18%) controls (p<0.05). In cCMV group, LSV was found in 51 (48.6%) symptomatic infants and in 13 (72.2%) asymptomatic patients (p>0.05). Overall, in the whole population of 95 patients with cCMV and abnormal HUS results, LSV (alone or with other findings) did not represent a risk factor for unfavorable neurological and hearing outcome. Similar results were obtained when we limited the analysis to the group of symptomatic cCMV patients. CONCLUSIONS: Although LSV is a common HUS finding in infants with cCMV infection, its presence is not predictive of an adverse outcome. Our data suggest that HUS as a single neuroimaging investigation is unreliable in selecting candidates to antiviral therapy, mainly in presence of LSV as isolated finding.
