Fever without source (FWS) in infants is a frequent cause of consultation at the emergency department, and the emergence of SARS-CoV-2 could affect the approach to those infants. The aim of this study is to define the clinical characteristics and rates of bacterial coinfections of infants < 90 days with FWS as the first manifestation of SARS-CoV-2 infection. This is a cross-sectional study of infants under 90 days of age with FWS and positive SARS-CoV2 PCR in nasopharyngeal swab/aspirate, attended at the emergency departments of 49 Spanish hospitals (EPICO-AEP cohort) from March 1 to June 26, 2020. Three hundred and thirty-three children with COVID-19 were included in EPICO-AEP. A total of 67/336 (20%) were infants less than 90 days old, and 27/67(40%) presented with FWS. Blood cultures were performed in 24/27(89%) and were negative in all but one (4%) who presented a
Streptococcus mitis
bacteremia. Urine culture was performed in 26/27(97%) children and was negative in all, except in two (7%) patients. Lumbar puncture was performed in 6/27(22%) cases, with no growth of bacteria. Two children had bacterial coinfections: 1 had UTI and bacteremia, and 1 had UTI. C-reactive was protein over 20 mg/L in two children (one with bacterial coinfection), and procalcitonin was normal in all. One child was admitted to the pediatric intensive care unit because of apnea episodes. No patients died.
Conclusion
: FWS was frequent in infants under 90 days of age with SARS-CoV-2 infection. Standardized markers to rule out bacterial infections remain useful in this population, and the outcome is generally good.
What is Known:
• Fever without source (FWS) in infants is a common cause of consultation at the emergency department, and young infants have a higher risk of serious bacterial infections (SBI).
• The emergence of the new coronavirus SARS-CoV-2 could affect the approach to young infants with FWS in the emergency department. management of those children is a challenge because information about bacterial coinfection and prognosis is scarce.
What is New:
• SARS-CoV-2 infection should be ruled out in young infants (< 90 days of age) with FWS in areas with community transmission.
• Bacterial coinfection rarely coexists in those infants.
• Inflammatory markers were not increased in children without bacterial coinfection.
• Outcome is good in most patients.

Objective To describe the epidemiological and clinical characteristics of children hospitalized with 2009 pandemic influenza (pH1N1) in Madrid, Spain.
Patients/Methods We included patients less than 14 years of age admitted to one of 18 hospitals in Madrid, Spain, between May 1 and November 30, 2009 and diagnosed with pH1N1 by polymerase chain reaction. A retrospective chart review was conducted and data were compared by age, presence of high‐risk medical conditions, and pediatric intensive care unit (PICU) admission.
Results A total of 517 pH1N1 cases were included for final analysis. One hundred and forty‐two patients (27·5%) had predisposing underlying illnesses, with immunosuppression (36 children, 7%) and moderate persistent asthma (34, 6·6%) being the most common ones. Patients with underlying medical conditions had longer hospital stays [median 5, interquartile range (IQR) 3–8 days, versus median 4, IQR 3–6, P < 0·001] and required intensive care (20·4% versus 5·9%, P < 0·001) and mechanical ventilation more frequently than previously healthy children. Globally, intensive care was required for 51 patients (10%) and invasive mechanical ventilation for 12 (2%). Pediatric intensive care unit admission was significantly associated with abnormal initial chest X‐ray [Odds Ratio (OR) 3·5, 95% confidence interval (CI) 1·5–8·5], underlying neurological condition (OR 3·1, CI 1·2–7·5) and immunosuppression (OR 2·9, 1·2–6·8). Five patients (0·9%) died; two with severe neurological disease, two with leukemia, and one with a malignant solid tumor.
Conclusions Children with underlying medical conditions experienced more severe pH1N1 disease. Risk factors for admission to the PICU included underlying neurological conditions, immunosuppression and abnormal initial chest X‐ray.
Background
Chagas disease (CD) is an emergent disease in Europe, due to immigration. The aims of this study are to describe the epidemiological characteristics of a cohort of Chagas infected pregnant women in Spain, to assess the vertical transmission (VT) rate and evaluate the usefulness of the PCR in the diagnosis of congenital infection in the first months of life.
Methods
A descriptive, retrospective study including Chagas seropositive pregnant women who were attended at three tertiary hospitals in Madrid, from January 2012 to September 2016. Infants were examined by PCR at birth and 1 month later and serologically studied at 9 months or later. Children were considered infected when the parasite was detected by PCR at any age or when serology remained positive without decline over the age of 9 months.
Results
We included 122 seropositive-infected pregnant women, 81% were from Bolivia and only 8.2% had been treated before. 125 newborns were studied and finally 109 were included (12.8% lost the follow-up before performing the last serology). The VT rate was 2.75% (95% CI: 0,57–8,8%). Infected infants had positive PCR at birth and 1 month later. All of them were treated successfully with benznidazole (PCR and serology became negative later on). All non-infected children presented negative PCR. The mean age at which uninfected patients had negative serology was 10.5 months.
Conclusions
The VT rate is in keeping with literature and confirms the need to carry out a screening in pregnant women coming from endemic areas. PCR seems to be a useful tool to provide early diagnosis of congenital CD.
Introduction Etiological diagnosis of fever in sickle cell disease (SCD)
children is often challenging. Objective: to analyze the pattern of
inflammatory biomarkers in SCD febrile children and controls, in order
to determine predictors of severe bacterial infection (SBI). Methods
Prospective, case-control study of febrile and steady-state SCD children
carried out during 3 years. Clinical characteristics and laboratory
parameters, including 10 serum proinflammatory cytokines (IL-1β, IL-2,
IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-17a, IFN-γ and TNF-α) and
comparisons among study subgroups were analyzed. Results A total of 137
patients (78 cases and 59 controls) were included in the study; 78.5%
males, median age 4.1 (1.7-7.5) years. Four cases were diagnosed with
SBI, 41 viral infection (VI) and 33 no proven infection (NPI). IL-6 was
significantly higher in patients with SBI than in patients with VI or
NPI (163 vs 0.7 vs 0.7 pg/ml, p < 0.001), and undetectable in
all controls. The rest of the cytokines analyzed did not show any
significant difference. The optimal cut-off value of IL-6 for the
diagnosis of SBI was 125 pg/mL, with high PPV and NPV (PPV of 100% for
a prevalence of 5, 10 and 15% and NPV of 98.7%, 97.3% and 95.8% for
those prevalences, respectively). Conclusion We found that IL-6 (optimal
cut-off value of 125 pg/ml) was a very good marker for SBI in this
cohort of febrile SCD children, with high PPV and NPV. Therefore, IL-6
may be useful, alone or combined with other biomarkers, to guide the
management of these patients.
