RESUMEN
Studies concerning Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in paediatrics are limited to children mainly selected from hospitals, where patients with complications and co-morbidities are managed. We aimed to describe the course of the Coronavirus Disease 2019 (COVID-19) in a population of children enrolled by place of residence, from diagnosis to recovery, with a long-term clinical and serological follow-up. We identified patients aged <14 years old living in the Turin Health District 3 who had SARS-CoV-2 detected in at least one nasopharyngeal swab from 1st March to 1st June 2020. Epidemiological and clinical features of SARS-CoV-2 infection were collected by way of a telephone inquiry. Enrolled patients were tested for SARS-CoV-2 serology in order to provide evidence of seroconversion and persistence of specific antibodies some time after the infection. A total of 46 patients with SARS-CoV-2 infection/COVID-19 were identified. The main pattern of viral transmission was intra-family. Eleven children were totally asymptomatic. If symptoms appeared, the disease had a mild course. A single case of COVID-19-related respiratory insufficiency was registered. Among children who underwent serological evaluation, 84% had seroconversion. No significant differences in antibody development were found according to the age and the burden of the disease. Children tested farther from the primary infection had lower antibody index titre values than the others. In conclusion, COVID-19 has a good prognosis in paediatric age. Children are able to develop a valid immune response, although their index titres seem to decrease a long time after the disease.

OBJECTIVE: To evaluate clinical data and associated risk conditions of noncerebral systemic venous thromboembolism (VT), arterial thromboembolism (AT), and intracardiac thromboembolism (ICT) in neonates. STUDY DESIGN: Data analysis of first systemic thromboembolism occurring in 75 live neonates (0-28 days), enrolled in the Italian Registry of Pediatric Thrombosis from neonatology centers between January 2007 and July 2013. RESULTS: Among 75 events, 41 (55%) were VT, 22 (29%) AT, and 12 (16%) ICT; males represented 65%, and 71% were preterm. In 19 (25%), thromboembolism was diagnosed on the first day of life. In this "early onset" group, prenatal-associated risk conditions (maternal/placental disease) were reported in 70% and inherited thrombophilia in 33%. Postnatal risk factors were present in 73%; infections and central vascular catheters in 56% and 54% VT, respectively, and in 67% ICT vs 27% AT (<.05). Overall mortality rate was 15% and significant thromboembolism-related sequelae were reported in 16% of discharged patients. CONCLUSIONS: This report from the Registro Italiano Trombosi Infantili, although limited by representing an uncontrolled case series, can be used to develop future clinical trials on appropriate management and prevention of neonatal thrombosis, focusing on obstetrical surveillance and monitoring of critically ill neonates with vascular access. A thrombosis risk prediction rule specific for the neonatal population should be developed through prospective controlled studies.

OBJECTIVE: Numerous fetal placenta vascular lesions seem to be a predisposing condition for some types of perinatal disease. Placental disease and newborn thromboses might be both manifestations of the same underlying disorder. Objective of this study is to describe pathological lesions of the placenta in newborns with perinatal thrombosis. STUDY DESIGN: We present retrospective data review and analysis regarding neonates admitted at our neonatal intensive care unit and diagnosed with an episode of thromboembolic events (TE) in the period from 2009 to 2013; among them we report three cases of perinatal thrombosis in newborns whose placentas demonstrated fetal thrombotic vasculopathy (FTV). RESULTS: In all the three cases a prothrombotic maternal condition was found, and in one patient a maternal infection with chorioamnionitis; the histological examination of placenta, required soon after birth for maternal pathological conditions, was important in confirming and explaining the clinical diagnosis of neonatal thrombosis and for the management of future pregnancies. CONCLUSION: It is proposed that placenta of newborns with TE in first days of life should always be examined, for its association with FTV and thus the storage of placentas for a week after birth should be routinely implemented.
