BackgroundEmerging evidence shows that both adults and children may develop post-acute sequelae of SARS-CoV-2 infection (PASC). The aim of this study is to characterise and compare long-term post-SARS-CoV-2 infection outcomes in adults and children in a defined region in Italy.MethodsA prospective cohort study including children (≤18 years old) with PCR-confirmed SARS-CoV-2 infection and their household members. Participants were assessed via telephone and face-to-face visits up to 12 months post-SARS-CoV-2 diagnosis of household index case, using the ISARIC COVID-19 follow-up survey.ResultsOf 507 participants from 201 households, 56.4% (286/507) were children, 43.6% (221/507) adults. SARS-CoV-2 positivity was 87% (249/286) in children, and 78% (172/221) in adults. The mean age of PCR positive children was 10.4 (SD = 4.5) and of PCR positive adults was 44.5 years (SD = 9.5), similar to the PCR negative control groups [children 10.5 years (SD = 3.24), adults 42.3 years (SD = 9.06)]. Median follow-up post-SARS-CoV-2 diagnosis was 77 days (IQR 47–169). A significantly higher proportion of adults compared to children reported at least one persistent symptom (67%, 68/101 vs. 32%, 57/179, p < 0.001) at the first follow up. Adults had more frequently coexistence of several symptom categories at both follow-up time-points. Female gender was identified as a risk factor for PASC in adults (p 0.02 at 1–3 months and p 0.01 at 6–9 months follow up), but not in children. We found no significant correlation between adults and children symptoms. In the paediatric group, there was a significant difference in persisting symptoms between those with confirmed SARS-CoV-2 infection compared to controls at 1–3 months follow up, but not at 6–9 months. Conversely, positive adults had a higher frequency of persisting symptoms at both follow-up assessments.ConclusionOur data highlights that children can experience persistent multisystemic symptoms months after diagnosis of mild acute SARS-CoV-2 infection, although less frequently and less severely than co-habitant adults. There was no correlation between symptoms experienced by adults and children living in the same household. Our data highlights an urgent need for studies to characterise PASC in whole populations and the wider impact on families.

Previous studies assessing the prevalence of COVID-19 sequelae in children have included either a small number of children or a short follow-up period, or have only focused on hospitalized children. We investigated the prevalence of persistent symptoms amongst children and assessed the risk factors, including the impact of variants. A prospective cohort study included children (≤18 years old) with PCR-confirmed SARS-CoV-2 infection. The participants were assessed via telephone and face-to-face visits at 1–5, 6–9 and 12 or more months post-SARS-CoV-2 diagnosis using the ISARIC COVID-19 follow-up survey. Of the 679 children enrolled, 51% were female; 488 were infected during the wild virus wave, and 29 were infected with the Alpha, 42 with the Delta and 120 with the Omicron variants. Fatigue (19%), headache (12%), insomnia (7.5%), muscle pain (6.9%) and confusion with concentration issues (6.8%) were the most common persistent symptoms. Families reported an overall improvement over time, with 0.7% of parents interviewed at 12 months or more of the follow-up period reporting a poor recovery. Patients that had not recovered by 6–9 months had a lower probability of recovering during the next follow-up period. Children infected with a variant or the wild virus had an overall similar rate of persistent symptoms (although the pattern of reported symptoms differed significantly) and recovery rates. Conclusions: Recovery rates after SARS-CoV-2 infection improved as time passed from the initial infection, ranging from 4% of children having poor recovery at 1–5 months’ follow-up to 1.3% at 6–9 months and 0.7% at 12 months. The patterns of persistence changed according to the variants involved at the time of infection. This study reinforces that a subgroup of children develop long-lasting persistent symptoms and highlights the need for further studies investigating the reasons behind the development of PCC.

Introduction Spinal dysraphism (SD) is a general term used to refer to developmental abnormalities of the spine that involves many clinical conditions including myelomeningocele (MMC). In these patients, neurogenic bladder (NB) is a common and predisposing factor for renal damage; the most frequently used approach to manage this situation is based on clean intermittent catheterization (CIC) and anticholinergic drugs. Urinary tract infections (UTIs) are a significant concern for these patients, and antibiotic prophylaxis is frequently used even if it is still a debated topic of literature. The purpose of this paper is to investigate the role and the real effectiveness of antibiotic prophylaxis in the reduction of incidence of UTIs in patients with spina bifida performing CIC. Methods We collected data of all patients performing CIC, who did their last follow-up visit in the period between January 2019 and January 2021, followed at the children multidisciplinary Spina Bifida Center of A. Gemelli Hospital in Rome. Data collected included age at referral, gender, type of SD lesion, serum creatinine and cystatin C levels, the use of anticholinergic medications, antibiotic prophylaxis and type of prophylaxis (oral/endovesical), age of starting prophylaxis with its duration/adherence, number of CIC/day and its duration, episodes of UTIs in the 2 years prior to the last follow-up, and presence and grade of vesical-ureteric reflux (VUR) on cystourethrogram. Results A total of 121 patients with SD performing CIC was included in the study; 66 (54%) presented ≥ 1 episode of UTIs in the last two years and 55 (46%) none. During the study period, 85 (70%) patients received antibiotic prophylaxis (ABP group) and 36 (30%) did not (NABP group): no statistically significative difference in terms of UTI development was observed between the two groups (p = 0.17). We also evaluated compliance to the therapy; 71 patients (59%) took antibiotic prophylaxis constantly (CABP group) and 50 (41%) did not do antibiotic prophylaxis constantly or did not do antibiotic prophylaxis at all (NCABP group): we observed a statistically significative difference in terms of UTIs with a 2.2 times higher risk of development at least one episode of UTIs in NCABP group. Conclusion In conclusion, antibiotic prophylaxis performed constantly, without interruption, is associated with a lower risk of developing urinary tract infections and consequently to develop renal failure in adulthood.

Objective: The aim of this study was to evaluate the prevalence of innocent heart murmurs in children affected by nocturnal enuresis (NE). Material and methods: We enrolled a total of 401 children (G1), 300 males and 101 females, aged 5-15 years, affected by NE and referred to the Service of Pediatrics, "Campus Bio-Medico" University Hospital of Rome, from September 2013 to September 2018, into the study. The control group was composed of 394 children without NE (G2). The study was carried out in compliance with the Helsinki Declaration. Results: The prevalence of innocent heart murmurs in G2 was 6.34%. This condition was significantly more frequent in children who suffered from NE. Indeed, in G1, the prevalence of innocent heart murmurs was 21.45%, although there were few differences between the children with monosymptomatic NE and nonmonosymptomatic NE; moreover, this prevalence was higher in males. Conclusion: These findings made us aware of the presence of possible underlying mechanisms, which explain the association between a higher prevalence of innocent heart murmurs and enuresis, and further studies are required to explore this issue.
