Evaluation of Risk for Thromboembolic Events in Pediatric Inflammatory Bowel Disease.

OBJECTIVES: The occurrence of thrombotic events in adult patients with inflammatory bowel disease (IBD) is linked to multiple interactions between hereditary and acquired risk factors. There are few published data concerning children with iBD. The aim of this study was to investigate the presence of thromboembolic risk factors also in children with iBD. METHODS: We enrolled three groups of children: one with Crohn disease (cD), one with ulcerative colitis (Uc), and a control group of healthy subjects. For all the participants the potential thromboembolic risk was evaluated clinically and with laboratory tests. RESULTS: We studied: 30 children (25.6%) with CD, 28 (23.9%) with UC, and 59 (50.4%) healthy control subjects. Regarding Pediatric Crohn Disease Activity Index, no significant differences between thromboembolic risk factors and disease activity were detected. Instead, in the patients with UC, stratified with the Pediatric Ulcerative Colitis Activity Index, there was a statistically significant difference in serum fibrinogen levels between patients with mild and moderate/severe disease [3.8 (3.2-4.5) g/L vs 5.7 (4.8-6.2) g/L, P  < 0.0032]. serum homocysteine levels were lower in healthy controls than in CD (P = 0.176) and UC (P = 0.026). An increased level ofhomocysteine in UC with a homozygous mutation in the methylene tetrahydrofolate reductase C677T gene was also observed. CONCLUSIONS: Our study showed that children with IBD have clinical features, acquired and congenital factors that can increase thrombotic risk, similarly to adults.

Comparing parental distress and children's difficulties between parents of children with rheumatic diseases and parents of healthy children in families facing the COVID-19 pandemic.

The COVID-19 pandemic could be a threat for the health status of children with a chronic condition. The present study aimed to explore parents' and children's psychological adjustment during the current pandemic, pursuing a triple objective: to compare the psychological adjustment of parents of children with pediatric rheumatic diseases (PRDs) and parents of healthy children; to analyze children's psychological symptoms (emotional problems and hyperactivity) before and during the COVID-19 pandemic, and with or without a PRDs diagnosis; to explore the associations of children's emotional problems and hyperactivity with parents' psychological adjustment, parent-child interactions and belonging or not to families with PRDs. This cross-sectional study involved 56 parents of children with PRDs and 53 parents of healthy children. Self-report questionnaires about parents' depression, anxiety, parenting stress, and children's emotional symptoms and hyperactivity-inattention were administered. No differences were detected on psychological adjustment between parents of children with PRDs and parents of healthy children. Parents of children with PRDs reported statistically significant higher levels of children's emotional problems and hyperactivity before the pandemic, compared to parents of healthy children; during COVID-19 pandemic, emotional symptoms increased for both groups, while hyperactivity-inattention symptoms increased only in the group of healthy children. Children's emotional difficulties were associated with higher levels of parental anxiety, worse parent-child interaction and having PRDs; children's hyperactivity symptoms were related to parent-child difficult interaction and higher levels of parental depression. Findings suggest the importance to target the children in relation to their parents, when approaching the psychological aspects of PRDs.

Effects of N95 Mask Use on Pulmonary Function in Children.

OBJECTIVE: To assess whether use of an N95 mask by children is associated with episodes of desaturation or respiratory distress. STUDY DESIGN: Twenty-two healthy children were assigned at random to 1 of 2 groups: one group wearing N95 masks without an exhalation valve and the other group wearing N95 masks with an exhalation valve. We tracked changes in partial pressure of end-tidal carbon dioxide (PETCO2), oxygen saturation, pulse rate, and respiratory rate over 72 minutes of mask use. All subjects were monitored every 15 minutes, the first 30 minutes while not wearing a mask and the next 30 minutes while wearing a mask. They then performed a 12-minute walking test. RESULTS: The children did not experience a statistically significant change in oxygen saturation or pulse rate during the study. There were significant increases in respiratory rate and PETCO2 in the children wearing an N95 mask without an exhalation valve, whereas these increases were seen in the children wearing a mask with an exhalation valve only after the walking test. CONCLUSIONS: The use of an N95 mask could potentially cause breathing difficulties in children if the mask does not have an exhalation valve, particularly during a physical activity. We believe that wearing a surgical mask may be more appropriate for children.

The comprehensive clinic, laboratory, and instrumental evaluation of children with COVID-19: A 6-months prospective study.

OBJECTIVES: To perform a comprehensive clinic, laboratory, and instrumental evaluation of children affected by coronavirus disease (COVID-19). METHODS: Children with a positive result of nasopharyngeal swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) underwent laboratory tests, anal and conjunctival swab, electrocardiography, lung, abdomen, and cardiac ultrasound. Twenty-four-hour ambulatory blood pressure monitoring was performed if abnormal basal blood pressure. Patients were followed-up for 6 months. RESULTS: Three hundred and sixteen children were evaluated; 15 were finally included. Confirmed family member SARS-CoV-2 infection was present in all. Twenty-seven percent were asymptomatic. Anal and conjunctival swabs tests resulted negative in all. Patients with lower body mass index (BMI) presented significantly higher viral loads. Main laboratory abnormalities were: lactate dehydrogenase increasing (73%), low vitamin D levels (87%), hematuria (33%), proteinuria (26%), renal hyperfiltration (33%), and hypofiltration (13%). Two of the patients with hyperfiltration exhibited high blood pressure levels at diagnosis, and persistence of prehypertension at 6-month follow-up. No abnormalities were seen at ultrasound, excepting for one patient who exhibited B-lines at lung sonography. Immunoglobulin G seroconversion was observed in all at 1-month. CONCLUSIONS: Our study confirm that intra-family transmission is important. The significant higher viral loads recorded among patients with lower BMI, together with low vitamin D levels, support the impact of nutritional status on immune system. Renal involvement is frequent even among children with mild COVID-19, therefore prompt evaluation and identification of patients with reduced renal function reserve would allow a better stratification and management of patients. Seroconversion occurs also in asymptomatic children, with no differences in antibodies titer according to age, sex and clinical manifestations.

Serum IgG levels in children 6 months after SARS-CoV-2 infection and comparison with adults.

Since the outbreak of SARS-CoV-2 among the population has occurred quite recently, there is a lack of evidence on the long-term duration of antibody response, especially in children. It is therefore crucial to clarify this aspect, considering its implications in the development of successful surveillance strategies, therapies, and vaccinations. The aim of this study was to assess the antibody response in a children group after SARS-CoV-2 infection, and to compare it with that of their parents affected by SARS-CoV-2 infection. We enrolled 12 children and their parents, both groups being affected by COVID-19 in April 2020. In the children's group, we collected real-time RT-PCR cycle threshold (Ct) values and gene characterization of first nasal-throat swab at the time of diagnosis (T0); 30 days after the diagnosis (T30), we performed blood tests to detect anti-SARS-CoV-2 IgM and IgG. Finally, 180 days after the diagnosis (T180), we measured anti-SARS-CoV-2 IgG in both children and parents. In children, antibody levels declined significantly at 180 days (T180) after first measurement (T30). There were no significant differences in IgG level related to age, sex, and clinical manifestations. We found a significant correlation between IgG titers at T30 and Ct value of gene N. Children showed a lower level of antibodies against SARS-CoV-2 at T180 compared to their parents.Conclusion: Antibody responses in children waned 180 days after SARS-CoV-2 infection, and at the same time, their parents showed a different antibody response to the virus. These results highlight that serological tests should be used with caution in surveillance strategies among the general population. What is known: • Currently is not known how long antibody response will be maintained or if it protects from reinfection. • Recent reports in adults suggest that antibodies to SARS-CoV-2 declined several months after infection, but data are missing in pediatric age. What is new: • We showed that antibody responses to SARS-CoV-2 wane several months after infection also in children with quantitative differences in antibody levels between children and adults. • In this context, serological tests should be used with caution in surveillance strategies.

Lung ultrasound compared to chest X-ray for the diagnosis of CAP in children.

BACKGROUND: Community-acquired pneumonia (CAP) represents one of the most common infectious diseases among children. Diagnosis of CAP is mainly clinical. Chest X-ray (CXR) remains the gold standard for the diagnosis in severe or controversial conditions. Recently, some authors have focused on the application of ultrasound in lung diseases but the role of lung ultrasound (LUS) in the diagnosis of CAP is still debated. We aimed to study the concordance between LUS and CXR in evaluating specific signs of CAP. As a secondary aim, we sought to determine the sensitivity and specificity of LUS in CAP diagnosis compared with CXR. Finally, we evaluated the role of LUS during the follow up. METHODS: We enrolled 68 children (<16 years old) hospitalized from October 2018 to September 2019 with a clinical and radiological diagnosis of CAP (cases: N = 41), or with no respiratory diseases (controls: N = 27), in whom a CXR was performed for clinical indications. All the children underwent LUS during hospitalization. The average time needed to perform LUS was 5-10 min for each child, and 19/41 cases were re-evaluated by LUS and CXR 30 days after discharge. RESULTS: Lung ultrasound confirmed CAP diagnosis in 40/41 patients. Concordance between the two techniques was K = 0.88 for the right lung and K = 0.70 for the left lung. Lung ultrasound showed a sensitivity of 97% and a specificity of 96% compared with CXR. At the follow up, sensitivity increased to 100% while specificity was 94%. CONCLUSIONS: Our study showed a potential benefit of LUS compared with CXR in the diagnosis and the follow up of CAP.

Proteinuria and hematuria as early signs of renal involvement in juvenile idiopathic arthritis.

Objectives: To evaluate glomerular and tubular renal functions and analyze blood pressure in a cohort of pediatric patients with juvenile idiopathic arthritis (JIA). Methods: A total of 40 pediatric patients, 20 (50%) with JIA and 20 (50%) healthy control subjects, were studied, and performed the renal function on 24-h collection and the 24-h ambulatory blood pressure monitoring (ABPM). Moreover, we compared renal function and blood pressure trends between the groups of JIA patients with different disease activities. Results: No statistically significant differences were observed between patients with JIA and healthy children in terms of glomerular filtration rate (GFR), fractional excretion of sodium (FENa), tubular reabsorption of phosphate (TRP), and calcium-creatinine urine ratio (CaU/CrU). In contrast, we observed significantly higher values in JIA patients than in controls for the presence of hematuria (p < 0.0001) and proteinuria (p < 0.0001). Compared to the control group there were significantly higher values of hematuria and proteinuria/day in both groups of JIA patients with low disease activity (respectively, p = 0.0001 and p = 0.0002) and moderate disease activity (respectively p = 0.0001 and p = 0.0012). Systolic and diastolic dipping were significantly reduced in patients with JIA compared with healthy controls (p < 0.0001 and p < 0.0001, respectively). Conclusions: Our study showed that children with JIA, already in the early stages of the disease, have higher values of hematuria and proteinuria, which are early warning signs of nephropathy. Therefore, detailed screening of renal function and pressure monitoring in patients are necessary to monitor their evolution over time.

Effect of Bifidobacterium bifidum Supplementation in Newborns Born from Cesarean Section on Atopy, Respiratory Tract Infections, and Dyspeptic Syndromes: A Multicenter, Randomized, and Controlled Clinical Trial.

Cesarean section is considered a possible trigger of atopy and gut dysbiosis in newborns. Bifidobacteria, and specifically B. bifidum, are thought to play a central role in reducing the risk of atopy and in favoring gut eubiosis in children. Nonetheless, no trial has ever prospectively investigated the role played by this single bacterial species in preventing atopic manifestations in children born by cesarean section, and all the results published so far refer to mixtures of probiotics. We have therefore evaluated the impact of 6 months of supplementation with B. bifidum PRL2010 on the incidence, in the first year of life, of atopy, respiratory tract infections, and dyspeptic syndromes in 164 children born by cesarean (versus 249 untreated controls). The results of our multicenter, randomized, and controlled trial have shown that the probiotic supplementation significantly reduced the incidence of atopic dermatitis, upper and lower respiratory tract infections, and signs and symptoms of dyspeptic syndromes. Concerning the gut microbiota, B. bifidum supplementation significantly increased α-biodiversity and the relative values of the phyla Bacteroidota and Actinomycetota, of the genus Bacteroides, Bifidobacterium and of the species B. bifidum and reduced the relative content of Escherichia/Shigella and Haemophilus. A 6-month supplementation with B. bifidum in children born by cesarean section reduces the risk of gut dysbiosis and has a positive clinical impact that remains observable in the following 6 months of follow-up.

Emergency Department Admissions of Children with Chest Pain before and during COVID-19 Pandemic.

OBJECTIVES: We compared the number of accesses, causes, and instrumental evaluations of chest pain in children between the pre-COVID-19 era and the COVID-19 period and analyzed the assessment performed in children with chest pain, highlighting unnecessary examinations. METHODS: We enrolled children with chest pain admitted to our emergency department between January 2019 and May 2021. We collected demographic and clinical characteristics and findings on physical examinations, laboratory tests, and diagnostic evaluations. Then, we compared the number of accesses, causes, and instrumental assessments of chest pain between the pre-COVID-19 era and the COVID-19 era. RESULTS: A total of 111 patients enrolled (mean age: 119.8 ± 40.48 months; 62 males). The most frequent cause of chest pain was idiopathic (58.55%); we showed a cardiac origin in 4.5% of the cases. Troponin determination was performed in 107 patients, and the value was high only in one case; chest X-rays in 55 cases and echocardiograms in 25 cases showed pathological findings, respectively, in 10 and 5 cases. Chest pain accesses increased during the COVID-19 era (p < 0.0001), with no differences in the causes of chest pain between the two periods. CONCLUSIONS: The increase in accesses for chest pain during the COVID-19 pandemic confirms that this symptom generates anxiety among parents. Furthermore, our findings demonstrate that the evaluation of chest pain is still extensive, and new chest pain assessment protocols in the pediatric age group are needed.

Efficacy of Burosumab Every 2 Weeks in an Adult with X-Linked Hypophosphatemia: Should We Learn from Children?

X-linked hypophosphatemia is a genetic condition that leads to fibroblast-growth-factor 23 (FGF23) increase, causing phosphate renal wasting. Since 2018, burosumab, an anti-FGF23 antibody, has been used for this disease with different dosage in children and adults. We report the case of burosumab administration every 2 weeks, as usually done in children. We retrospectively evaluated parathormone (PTH), alkaline phosphatase, serum phosphate, tubular reabsorption of phosphate (TRP), and 25OH vitamin D every 2 weeks in a 29-year-old man with nephrocalcinosis and tertiary hyperparathyroidism who did not respond to standard treatment with burosumab nor to maximum dosage and was treated with burosumab 90 mg every 2 weeks. His serum phosphate and TRP increased with this regimen compared with 4 weeks frequency (respectively 1.74 ± 0.26 mg/dL vs. 2.3 ± 0.19 mg/dL [p 0.0004] and 71.3% ± 4.8% vs. 83.9% ± 7.9% [p 0.01]) with decrease in PTH (183 ± 24.7 pg/mL vs. 109 ± 12.2 pg/mL [p 0.04]). Burosumab may be a good choice in adult patients with X-linked hypophosphatemia; new data are needed regarding the increase in dosage and/or frequency of administration as usually done in children, to achieve disease control.

Post-Infectious Acute Cerebellar Ataxia Treatment, a Case Report and Review of Literature.

BACKGROUND: infectious mononucleosis is very common during childhood and neurological manifestations are extremely rare. However, when they occur, an appropriate treatment must be undertaken to reduce morbidity and mortality as well as to ensure appropriate management. METHODS: we describe the clinical and neurological records of a female patient with post-EBV acute cerebellar ataxia, whose symptoms rapidly resolved with intravenous immunoglobulin therapy. Afterwards, we compared our results with published data. RESULTS: we reported the case of an adolescent female with a 5-day history of sudden asthenia, vomiting, dizziness, and dehydration, with a positive monospot test and hypertransaminasemia. In the following days, she developed acute ataxia, drowsiness, vertigo, and nystagmus with a positive EBV IgM titer, confirming acute infectious mononucleosis. The patient was clinically diagnosed with EBV-associated acute cerebellitis. A brain MRI showed no acute changes and a CT scan showed hepatosplenomegaly. She started therapy with acyclovir and dexamethasone. After a few days, because of her condition's deterioration, she received intravenous immunoglobulin and demonstrated a good clinical response. CONCLUSIONS: although there are no consensus guidelines for the treatment of post-infectious acute cerebellar ataxia, early intervention with intravenous immunoglobulin might prevent adverse outcomes, especially in cases that do not respond to high-dose steroid therapy.

Point-of-Care Thoracic Ultrasound in Children: New Advances in Pediatric Emergency Setting.

Point-of-care thoracic ultrasound at the patient's bedside has increased significantly recently, especially in pediatric settings. Its low cost, rapidity, simplicity, and repeatability make it a practical examination to guide diagnosis and treatment choices, especially in pediatric emergency departments. The fields of application of this innovative imaging method are many and include primarily the study of lungs but also that of the heart, diaphragm, and vessels. This manuscript aims to describe the most important evidence for using thoracic ultrasound in the pediatric emergency setting.

Facing Pediatric Rheumatic Diseases: The Role of Disease Activity and Parental Emotion Regulation Strategy in Parents' and Children's Psychological Adjustment.

BACKGROUND: Pediatric rheumatic diseases (PRDs) are a group of chronic disorders that start in childhood and are characterized by periodic exacerbations and remissions of symptoms, with limitations in family, school, and social activities. The aim of this study was to detect differences in parents' psychological adjustment and emotion regulation strategies, and parent-reported children's adjustments in families of children with active and inactive PRDs. METHODS: Fifty-four parents (38 mothers and 16 fathers) of children with PRD were recruited from a pediatric unit. Disease activity was evaluated by their pediatric rheumatologist, while parents' depressive and anxiety symptoms, emotion regulation strategies, and children's emotional difficulties and hyperactivity-inattention symptoms were assessed through a web-based survey. RESULTS: Parents of children with active PRDs reported higher levels of their child's emotional difficulties and hyperactivity-inattention symptoms. Linear regression analysis demonstrated that having a child in the active phases of PRD and lower use of cognitive reappraisal lead to higher children's emotional symptoms, while active disease, low use of cognitive reappraisal, and greater expressive suppression were associated with higher hyperactivity-inattention symptoms. Our study highlights that children with PRDs and their parents may be at increased risk for psychological problems, especially during the active disease phase, highlighting the importance of a multidisciplinary approach.

Evaluation of Renal Function and Scars in Children With Primary Vesicoureteral Reflux.

OBJECTIVE: To evaluate growth, glomerular and tubular function, renal damage, scars in children affected by primary VUR. METHODS: We retrospectively evaluated the clinical records of our Unit from January 2006 to September 2020. For each patient we evaluated growth, laboratoristic and scintigraphic glomerular and tubular function, renal damage and collective system urodynamics at baseline and at the last visit. RESULTS: We enrolled 41 patients affected by primary VUR and treated with continuous antibiotic prophylaxis. Glomerular function and urodynamics did not change over time. EFNa directly correlated with weight (r 0.44 P .004) and TRP inversely correlated with severity of reflux (r -0.32, P .04). Female sex was associated to nephrolithiasis (OR 17.0, P .02) and proteinuria (at T0 OR 5.8 P .03 at T1 OR 5.8, P .03). Daily proteinuria increased with age (r 0.66, P <.0001 at T0 and r 0.44 P .004 at T1) while protein-to-creatinine ratio decreased. Renal scars at T0 inversely correlated with glomerular and tubular function at T1 but they did not correlate with severity or laterality of reflux. CONCLUSION: Even if renal function remains stable through years, it is critical to identify the subjects with significant congenital renal damage.

Adenomesenteritis following SARS-CoV-2 Vaccination in Children: A Case Report and Review of The Literature.

At present, the vaccine authorized in children aged 5 years and older is the BNT162b2 messenger RNA COVID-19 vaccine. Unlike adults, there is limited data available in the pediatric age describing adverse events after vaccine. We report a case of adenomesenteritis in a young girl following the first dose of vaccine.

Cross-Sectional Survey on BNT162b2 mRNA COVID-19 Vaccine Serious Adverse Events in Children 5 to 11 Years of Age: A Monocentric Experience.

OBJECTIVE: Our aim was to evaluate the safety of COVID-19 vaccine in children resident in the Latina Local Health Authority. METHODS: We conducted a telephone survey among children aged 5-11 years receiving BNT162b2 mRNA COVID-19 vaccine between December 15 and 21. The main outcomes included the presence of allergic reactions or anaphylaxis, adverse events after 24-48 h, 7 and 20 days of taking the first and second doses of medications, and documented SARS-CoV-2 infection after vaccination. The information obtained was automatically linked to a spreadsheet and analyzed. RESULTS: 569 children were enrolled. The mean age was 114 ± 4.24 months; there were 251 males in the study. The vaccine showed a favorable safety profile; no anaphylaxis or serious adverse events were reported. The most common symptoms both after the first and second dose were injection site reactions, asthenia, and headache. Injection site reactions were more frequent after the first dose (p = 0.01), while systemic symptoms were more frequent after the second dose (p = 0.022). These symptoms were more frequent in patients with comorbidities (p = 0.0159). CONCLUSION: Our findings confirm the safety of COVID-19 vaccine in children younger 11 years and could be useful to promote its diffusion in pediatric ages in order to achieve "herd immunity" and prevent the virus's circulation.
