During the COVID‐19 pandemic, chilblain‐like lesions have been reported in mildly symptomatic children and adolescents. We present four children investigated for suspected COVID‐19 infection who presented with acral skin findings and mild systemic symptoms. Histology from one case showed signs of vasculitis with evident fibrin thrombus.
Pulmonary complications in adults who recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been reported even in minimally symptomatic patients. In this study, lung ultrasound (LUS) findings and pulmonary function of children who recovered from an asymptomatic or mildly symptomatic SARS-CoV-2 infection were evaluated. We prospectively followed up for at least 30 days patients younger than 18 years who recovered from SARS-CoV-2 infection at the Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan (Italy). All enrolled patients underwent LUS. Airway resistance measured by the interrupter technique test was assessed in subjects aged 4–6 years, whereas forced spirometry and measurement of diffusing capacity of the lungs for carbon monoxide were performed in subjects older than 6 years. To evaluate a possible correlation between pulmonary alterations and immune response to SARS-CoV-2, two semiquantitative enzyme immune assays were used. We enrolled 16 out of 23 eligible children. The median age of enrolled subjects was 7.5 (0.5–10.5) years, with a male to female ratio of 1.7. No subject presented any abnormality on LUS, airway resistance test, forced spirometry, and diffusing capacity of the lungs for carbon monoxide. On the other hand, all subjects presented Ig G against SARS-CoV-2. In contrast in adults, we did not detect any pulmonary complications in our cohort. These preliminary observations suggest that children with an asymptomatic or mildly symptomatic SARS-CoV-2 infection might be less prone to develop pulmonary complications than adults.
It is not known whether cytokine levels in sputum may be used as outcome measures after parenteral antibiotic therapy in cystic fibrosis (CF) patients. Here, we assessed the effects of antibiotic therapy on cytokine levels in sputum and serum obtained from young CF patients. Thirty-two CF patients (14 females; mean age, 18.6 years; range, 11.4-35.7 years), consecutively admitted at the CF Center of Milan for parenteral antibiotic therapy during pulmonary exacerbation, were enrolled in the study. Before and after 21 days (range, 5-41) of intravenous antibiotic treatment, all patients underwent routine laboratory determinations (including white blood cell (WBC) count and C-reactive protein (CRP)), a chest X-ray, pulmonary function tests (forced expiratory volume in 1 sec (FEV1) and forced vital capacity (FVC) as % predicted), and sputum cultures. Interleukin (IL)-6, IL-8, IL-10, and tumor necrosis factor (TNF)-alpha levels in serum and sputum samples were determined by means of immunometric assays. After therapy, FEV1 and FVC significantly improved (median increase of 7.5% and 8.5% predicted, respectively), while CRP and WBC count were significantly decreased (median values from 14 to 5.5 mg/dl and from 8,350 to 7,400 n/mm3, respectively). While levels of IL-6 and IL-10 in sputum were generally undetectable, IL-8 and TNF-alpha were always measurable, and IL-8 levels significantly decreased after antibiotic treatment (median values from 7,165 to 5,415 pg/ml). Following antibiotic therapy, IL-8 and TNF-alpha levels in sputum were inversely related with both FEV(1) and FVC. In conclusion, TNF-alpha and IL-8 levels in sputum of young CF patients with pulmonary exacerbation were always detectable and may be useful, noninvasive outcome measures to assess response to therapy in CF patients.
Children have been suggested as the facilitators of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission and amplification, 1 because many affected children might be asymptomatic. 2,3 Accordingly, social and public health policies, such as school closure, have been implemented in many countries. However, the role of children in asymptomatically carrying SARS-CoV-2 needs to be further explored. In this study, we investigated the frequency of individuals carrying SARS-CoV-2 among children admitted for noninfectious conditions and without any SARS-CoV-2-associated symptoms or signs and compare it with the frequency of individuals carrying SARS-CoV-2 among a similar adult population.
Summary The long‐term effects of liver transplantation on nutritional status, body composition and pulmonary function in patients with liver disease associated with cystic fibrosis (CF) are poorly defined. We studied 15 patients with CF‐associated biliary cirrhosis and severe portal hypertension. Seven underwent liver transplantation (age: 14.8 ± 6.2 years), and eight were treated conservatively (age: 15.9 ± 6.7 years). All patients were evaluated at baseline and thereafter yearly for a median duration of 5 years. During follow‐up, transplanted patients gained weight and showed a significant increment in body mass index (P < 0.004), whereas patients without transplantation remained stable (P = 0.063). Baseline bone mineral content (dual energy X‐ray absorptiometry scan) was lower than normal in all patients (more in transplanted patients) and increased in transplanted patients (P < 0.05), but not in patients without transplantation. In both groups percent body fat did not change, whereas fat free mass increased only in the transplant group (P = 0.06) (P < 0.03 versus nontransplanted patients). Only in transplanted patients’ plasma concentrations of vitamin E and A increased (P < 0.05 versus nontransplanted patients). Forced espiratory volume in 1 s and forced vital capacity showed similar deterioration in transplanted and in nontransplanted patients. Liver transplantation is associated with long‐term beneficial effects on the nutritional status of CF patients and seems to favor bone mineralization.
IMPORTANCESevere gastrointestinal (GI) manifestations have been sporadically reported in children with COVID-19; however, their frequency and clinical outcome are unknown. OBJECTIVE To describe the clinical, radiological, and histopathologic characteristics of children with COVID-19 presenting with severe GI manifestations to identify factors associated with a severe outcome.
Acute moderate to severe gastroenteritis is traditionally associated with hypernatremia but recent observations suggest that hypernatremia is currently less common than hyponatremia. The latter has sometimes been documented also in children with acute community-acquired diseases, such as bronchiolitis and pyelonephritis. We investigated the prevalence of dysnatremia in children with acute moderate severe gastroenteritis, bronchiolitis and pyelonephritis. This prospective observational study included 400 consecutive previously healthy infants ≥4 weeks to ≤24 months of age (232 males and 168 females): 160 with gastroenteritis and relevant dehydration, 160 with moderate-severe bronchiolitis and 80 with pyelonephritis admitted to our emergency department between 2009 and 2017. Circulating sodium was determined by means of direct potentiometry. For analysis, the Kruskal-Wallis test and the Fisher’s exact test were used. Hyponatremia was found in 214 of the 400 patients. It was common in gastroenteritis (43%) and significantly more frequent in bronchiolitis (57%) and pyelonephritis (68%). Patients with hyponatremia were significantly younger than those without hyponatremia (3.9 [1.6–13] versus 7.5 [3.4–14] months). The gender ratio was similar in children with and without hyponatremia. Hyponatremia was associated with further metabolic abnormalities (hypokalemia, hyperkalemia, metabolic acidosis or metabolic alkalosis) in gastroenteritis (71%) and pyelonephritis (54%), and always isolated in bronchiolitis. In conclusion, hyponatremia is common at presentation among previously healthy infants with gastroenteritis, bronchiolitis or pyelonephritis. These data have relevant consequences for the nutrition and rehydration management in these conditions.
The first study on sodium level measured by the direct potentiometry in infants with bronchiolitis points out that the prevalence of hyponatremia is two-fold higher than so far reported.
