          Abstract

          Background

          The first Covid-19 pandemic affected the epidemiology of several diseases. A general reduction in the emergency department (ED) accesses was observed during this period, both in adult and pediatric contexts.

          Methods

          This retrospective study was conducted on the behalf of the Italian Society of Pediatric Nephrology (SINePe) in 17 Italian pediatric EDs in March and April 2020, comparing them with data from the same periods in 2018 and 2019. The total number of pediatric (age 0–18 years) ED visits, the number of febrile urinary tract infection (UTI) diagnoses, and clinical and laboratory parameters were retrospectively collected.

          Results

          The total number of febrile UTI diagnoses was 339 (73 in 2020, 140 in 2019, and 126 in 2018). During the first Covid-19 pandemic, the total number of ED visits decreased by 75.1%, the total number of febrile UTI diagnoses by 45.1%, with an increase in the UTI diagnosis rate (+ 121.7%). The data collected revealed an increased rate of patients with two or more days of fever before admission ( p = 0.02), a significant increase in hospitalization rate (+ 17.5%, p = 0.008) and also in values of C reactive protein (CRP) ( p = 0.006). In 2020, intravenous antibiotics use was significantly higher than in 2018 and 2019 (+ 15%, p = 0.025). Urine cultures showed higher Pseudomonas aeruginosa and Enterococcus faecalis percentages and lower rates of Escherichia coli ( p = 0.02).

          Conclusions

          The first wave of the Covid-19 pandemic had an essential impact on managing febrile UTIs in the ED, causing an absolute reduction of cases referring to the ED but with higher clinical severity. Children with febrile UTI were more severely ill than the previous two years, probably due to delayed access caused by the fear of potential hospital-acquired Sars-Cov-2 infection. The possible increase in consequent kidney scarring in this population should be considered.

          COVID-19 in children and adolescents in Europe: a multinational, multicentre cohort study

          Summary Background To date, few data on paediatric COVID-19 have been published, and most reports originate from China. This study aimed to capture key data on children and adolescents with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection across Europe to inform physicians and health-care service planning during the ongoing pandemic. Methods This multicentre cohort study involved 82 participating health-care institutions across 25 European countries, using a well established research network—the Paediatric Tuberculosis Network European Trials Group (ptbnet)—that mainly comprises paediatric infectious diseases specialists and paediatric pulmonologists. We included all individuals aged 18 years or younger with confirmed SARS-CoV-2 infection, detected at any anatomical site by RT-PCR, between April 1 and April 24, 2020, during the initial peak of the European COVID-19 pandemic. We explored factors associated with need for intensive care unit (ICU) admission and initiation of drug treatment for COVID-19 using univariable analysis, and applied multivariable logistic regression with backwards stepwise analysis to further explore those factors significantly associated with ICU admission. Findings 582 individuals with PCR-confirmed SARS-CoV-2 infection were included, with a median age of 5·0 years (IQR 0·5–12·0) and a sex ratio of 1·15 males per female. 145 (25%) had pre-existing medical conditions. 363 (62%) individuals were admitted to hospital. 48 (8%) individuals required ICU admission, 25 (4%) mechanical ventilation (median duration 7 days, IQR 2–11, range 1–34), 19 (3%) inotropic support, and one (<1%) extracorporeal membrane oxygenation. Significant risk factors for requiring ICU admission in multivariable analyses were being younger than 1 month (odds ratio 5·06, 95% CI 1·72–14·87; p=0·0035), male sex (2·12, 1·06–4·21; p=0·033), pre-existing medical conditions (3·27, 1·67–6·42; p=0·0015), and presence of lower respiratory tract infection signs or symptoms at presentation (10·46, 5·16–21·23; p<0·0001). The most frequently used drug with antiviral activity was hydroxychloroquine (40 [7%] patients), followed by remdesivir (17 [3%] patients), lopinavir–ritonavir (six [1%] patients), and oseltamivir (three [1%] patients). Immunomodulatory medication used included corticosteroids (22 [4%] patients), intravenous immunoglobulin (seven [1%] patients), tocilizumab (four [1%] patients), anakinra (three [1%] patients), and siltuximab (one [<1%] patient). Four children died (case-fatality rate 0·69%, 95% CI 0·20–1·82); at study end, the remaining 578 were alive and only 25 (4%) were still symptomatic or requiring respiratory support. Interpretation COVID-19 is generally a mild disease in children, including infants. However, a small proportion develop severe disease requiring ICU admission and prolonged ventilation, although fatal outcome is overall rare. The data also reflect the current uncertainties regarding specific treatment options, highlighting that additional data on antiviral and immunomodulatory drugs are urgently needed.

            Reduction of hospitalizations for myocardial infarction in Italy in the COVID-19 era

            Abstract Aims To evaluate the impact of the COVID-19 pandemic on patient admissions to Italian cardiac care units (CCUs). Methods and Results We conducted a multicentre, observational, nationwide survey to collect data on admissions for acute myocardial infarction (AMI) at Italian CCUs throughout a 1 week period during the COVID-19 outbreak, compared with the equivalent week in 2019. We observed a 48.4% reduction in admissions for AMI compared with the equivalent week in 2019 (P < 0.001). The reduction was significant for both ST-segment elevation myocardial infarction [STEMI; 26.5%, 95% confidence interval (CI) 21.7–32.3; P = 0.009] and non-STEMI (NSTEMI; 65.1%, 95% CI 60.3–70.3; P < 0.001). Among STEMIs, the reduction was higher for women (41.2%; P = 0.011) than men (17.8%; P = 0.191). A similar reduction in AMI admissions was registered in North Italy (52.1%), Central Italy (59.3%), and South Italy (52.1%). The STEMI case fatality rate during the pandemic was substantially increased compared with 2019 [risk ratio (RR) = 3.3, 95% CI 1.7–6.6; P < 0.001]. A parallel increase in complications was also registered (RR = 1.8, 95% CI 1.1–2.8; P = 0.009). Conclusion Admissions for AMI were significantly reduced during the COVID-19 pandemic across Italy, with a parallel increase in fatality and complication rates. This constitutes a serious social issue, demanding attention by the scientific and healthcare communities and public regulatory agencies.

              Delayed access or provision of care in Italy resulting from fear of COVID-19

              During Italy's national lockdown for coronavirus disease 2019 (COVID-19), official hospital statistics in the period March 1–27, 2020, show substantial decreases—ranging from 73% to 88%—in paediatric emergency department visits compared with the same time period in 2019 and 2018 (figure ). Similarly, family paediatricians widely report a considerable reduction in clinic visits, although this is difficult to measure precisely. Figure Visits to paediatric emergency departments across five hospitals in Italy, March 1–27, 2020, compared with the same period in 2018 and 2019 Data are official hospital statistics (courtesy of the authors). Schools and sports activities have been closed since March 1 in Italy, so it is understandable that the numbers of acute infections and traumas among children are lower than usual. In addition, relatively few cases of COVID-19 among children have been reported. 1 As of April 2, the 1624 cases in the paediatric population ( 39°C) and the other presented with severe anaemia (haemoglobin 4·2 mg/dL) and respiratory distress after emergency department access was delayed. One of these patients died several days after hospital admission. One child presented with long-lasting convulsions after three previous episodes of convulsions had been treated at home without medical assistance; the patient was eventually diagnosed with bacterial pneumonia. A 3-year-old girl was admitted to hospital after 6 days at home with very high fever (>39°C), with a sepsis secondary to a pyelonephritis. A neonate was kept home despite vomiting for several days because of hypertrophic pyloric stenosis and arrived in the emergency department in hypovolaemic shock. Another child, aged 2 years, had been vomiting for several days and unable to eat before presenting with severe hypoglycaemia. One child arriving in the emergency department having been unable to pass faeces for more than a week was diagnosed with an abdominal mass of 15 cm diameter, later diagnosed as Wilm's tumour; the diagnosis by telephone from his paediatrician had been functional constipation. An adolescent with cerebral palsy and severe malnutrition got in touch with the hospital after 10 days of fever at home with increased oxygen needs, and died in the ambulance on the way to the hospital. The precise cause of fever and death was not ascertained but the adolescent was negative for COVID-19 infection. Another child with cerebral palsy, tracheotomy, and enteral nutrition died on route to the hospital after 3 days of bloody stools. A child with Mowat Wilson syndrome, in dialysis for chronic renal insufficiency, arrived at the hospital after 3 days of being “less active than usual” with capillary refill time of 4 s, heart rate of 50 beats per min, oxygen saturation level not detectable, mixed acidosis, and creatine 4 mg/dL; the child died after 4 days in the ICU. Of this small series of 12 cases, half of the children were admitted to an ICU and four died. In all cases, parents reported avoiding accessing hospital because of fear of infection with SARS-CoV-2. Furthermore, in five cases, the family had contacted health services before accessing care, but their health provider was unavailable because of the COVID-19 epidemic, or hospital access was discouraged because of the possible risk of infection. All cases were either negative for SARS-CoV-2 or had a clinical presentation (eg, diabetes) that did not justify a diagnostic test according to the national criteria. Notably, no death occurred in the same hospitals during the same period in 2019, and the total yearly number of paediatric deaths in these hospitals ranges from zero to three. These cases are clearly a small sample compared with the overall number of paediatric visits recorded in the five hospitals during this week (12 [2%] of 502). However, since delay in access to care was not monitored systematically, this small case series might underestimate the problem. We believe that further monitoring of access to routine clinical care is needed during the COVID-19 pandemic. There is a need to prevent delays in accessing hospital care and to increase provision of high-quality coordinated care by health-care providers. Both of these aspects should be considered as part of the overall public health impact of the COVID-19 pandemic, as evident in other epidemics,3, 4 and must be adequately monitored. Both the general population and health-care workers need clear guidance and information. Specifically, parents should be made fully aware that the risks of delayed access to hospital care for emergency conditions can be much higher than those posed by COVID-19. Specific duties and obligations of different types of health-care professionals should be clearly defined, taking into consideration the risk level of the working environment, the health-care worker's specialty, the probable harms and benefits of treatment, and competing obligations deriving from workers' multiple roles.4, 5
