Clinical utility of procalcitonin in febrile infants younger than 3 months of age visiting a pediatric emergency room: a retrospective single-center study. BMC Pediatr 2021; 21:109. [PMID: 33663442 PMCID: PMC7931518 DOI: 10.1186/s12887-021-02568-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2020] [Accepted: 02/24/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Fever in infants under 90 days of age is highly likely to be caused by a severe bacterial infection (SBI) and it accounts for a large number of patients visiting the pediatric emergency room. In order to predict the bacterial infection and reduce unnecessary treatment, the classic classification system is based on white blood cell (WBC) count, urinalysis, and x-ray, and it is modified and applied at each center by incorporating recently studied biomarkers such as c-reactive protein (CRP) or procalcitonin (PCT). This study analyzed the usefulness of PCT in predicting SBI when applied along with the existing classification system, including CRP, among infants less than 90 days old who visited with a fever at a single institution pediatric emergency center. METHODS We retrospectively reviewed the medical records of patients younger than 3 months of age who presented with fever at the Seoul Asan Medical Center pediatric emergency room between July 2017 and October 2018. RESULTS A total of 317 patients were analyzed, and 61 were diagnosed with SBI, among which urinary tract infection (UTI) accounted for the largest proportion (55/61, 90.2%). There were differences in WBC, neutrophil proportion, CRP, and PCT between the SBI group and the non-SBI group, and the AUC values of WBC, CRP, and PCT were 0.651, 0.804, and 0.746, respectively. When using the cut-off values of CRP and PCTs as 2.0 mg/dL and 0.3 ng/mL, respectively, the sensitivity and specificity for SBI were 49.2/89.5, and 54.1/87.5, respectively. WBC, CRP, and PCT were statistically significant for predicting SBI in multivariate analysis (odds ratios 1.066, 1.377, and 1.291, respectively). When the subjects were classified using the existing classification criteria, WBC and CRP, the positive predictive value (PPV) and negative predictive value (NPV) were 29.3 and 88.7%, respectively, and when PCT was added, the PPV and NPV were 30.7 and 92%, respectively, both increased. CONCLUSION PCT is useful for predicting SBI in children aged 3 months or less who visit the emergency room with a fever. It is useful as a single biomarker, and when used in conjunction with classic biomarkers, its diagnostic accuracy is further increased.

Abstract
We retrospectively examined the yield of a cerebrospinal fluid (CSF) multiplex real-time PCR assay of febrile young infants undergoing a full sepsis work-up. Eighty infants were included in the study: Forty-nine (61%) neonates and 31 (39%) 29-90 day-old patients were included in the study. A viral pathogen was detected in 59% (47/80) of the samples, human enterovirus in 53% (42/80) and Human parechovirus in 6% (5/80). The CSF of nearly half of the subjects with CNS infection was without pleocytosis; all CSF cultures were negative. Multiplex PCR CSF testing enhances the diagnosis of pathogen-specific viral CNS infection among febrile young infants.

Abstract
Background Diagnostic evaluation of febrile young infants is challenging. Empirical antimicrobial treatment is therefore common practice in this setting despite high percentage of causative viral infections. The objective of this study was to investigate the impact of rapid enterovirus cerebrospinal fluid polymerase chain reaction (CSF EV PCR) test on hospital length of stay (LOS) and antimicrobial treatment duration in young febrile infants. Methods Retrospective observational study comparing duration of antimicrobial treatment and hospital LOS before (May 1, 2014 - May 30, 2015, untested group) and after (June 1, 2015 - June 30, 2017, tested group) the introduction of rapid CSF EV PCR testing in infants < 90 days of age presenting with fever and CSF pleocytosis at the University Children’s Hospital Zurich. Additionally, the same variables were compared after test introduction between CSF EV PCR positive and negative children. Results One hundred twenty-eight children were enrolled in the study, 58 before and 70 after the introduction of rapid CSF EV PCR testing. Duration of antimicrobial treatment was significantly shortened in EV positive (n = 42) compared to both EV negative (n = 28) (median 18 h and 48 h, respectively, p < 0.001) and untested patients (n = 58) (median 18 h and 48 h, respectively, p < 0.001), and also in tested compared to untested group patients (median 36 vs 48 h, p < 0.001). Hospital LOS was significantly shortened in EV positive compared to EV negative patients (median 3 days and 4 days respectively, p = 0.013), while an overall reduction was not observed between tested and untested group patients. Conclusions In this study we demonstrate that antimicrobial treatment duration could be significantly shortened in neonates and young infants < 90 days of age with aseptic meningitis after the introduction of a rapid CSF EV PCR test compared to untested patients before test introduction.

Abstract
As infants with proven viral infection present lower risk of bacterial infection, we evaluated how molecular methods detecting viruses on respiratory secretions could contribute to etiological diagnostic of these febrile episodes. From November 2010 to May 2011, we enrolled all febrile infants <90 days presenting to emergency room. Standard workup included viral rapid antigenic test and viral culture on nasopharyngeal aspirate. Samples negative by rapid testing were tested by molecular methods. From 208 febrile episodes (198 infants) with standard techniques, rate of documented microbiological etiology was 13% at emergency department, 47% during hospitalization, and 64% with viral cultures. Molecular methods increased microbiologically documented etiology rate by 12%, to 76%. Contribution of molecular methods was the highest in infants without clinical source of infection, increasing documentation by 18%, from 50% to 68%. Making viral molecular results rapidly available could help identifying a higher proportion of infants at low risk of serious bacterial infection.

Abstract
Introduction: While fever is the main complaint among pediatric emergency services and high antibiotic prescription are observed, only a few studies have been published addressing this subject. Therefore this systematic review aims to summarize antibiotic prescriptions in febrile children at the ED and assess its determinants. Methods: We extracted studies published from 2000 to 2017 on antibiotic use in febrile children at the ED from different databases. Author, year, and country of publishing, study design, inclusion criteria, primary outcome, age, and number of children included in the study was extracted. To compare the risk-of-bias all articles were assessed using the MINORS criteria. For the final quality assessment we additionally used the sample size and the primary outcome. Results: We included 26 studies reporting on antibiotic prescription and 28 intervention studies on the effect on antibiotic prescription. In all 54 studies antibiotic prescriptions in the ED varied from 15 to 90.5%, pending on study populations and diagnosis. Respiratory tract infections were mostly studied. Pediatric emergency physicians prescribed significantly less antibiotics then general emergency physicians. Most frequent reported interventions to reduce antibiotics are delayed antibiotic prescription in acute otitis media, viral testing and guidelines. Conclusion: Evidence on antibiotic prescriptions in children with fever presenting to the ED remains inconclusive. Delayed antibiotic prescription in acute otitis media and guidelines for fever and respiratory infections can effectively reduce antibiotic prescription in the ED. The large heterogeneity of type of studies and included populations limits strict conclusions, such a gap in knowledge on the determining factors that influence antibiotic prescription in febrile children presenting to the ED remains.

Abstract
CONTEXT Enterovirus infection commonly causes fever in infants aged 0 to 90 days and, without testing, is difficult to differentiate from serious bacterial infection. OBJECTIVE To determine the cost savings of routine enterovirus testing and identify subgroups of infants with greater potential impact from testing among infants 0 to 90 days old with fever. DATA SOURCES Studies were identified systematically from published and unpublished literature by using Embase, Medline, the Cochrane database, and conference proceedings. STUDY SELECTION Inclusion criteria were original studies, in any language, of enterovirus infection including the outcomes of interest in infants aged 0 to 90 days. DATA EXTRACTION Standardized instruments were used to appraise each study. The evidence quality was evaluated using Grading of Recommendations Assessment, Development, and Evaluation criteria. Two investigators independently searched the literature, screened and critically appraised the studies, extracted the data, and applied the Grading of Recommendations Assessment, Development, and Evaluation criteria. RESULTS Of the 257 unique studies identified and screened, 32 were completely reviewed and 8 were included. Routine enterovirus testing was associated with reduced hospital length of stay and cost savings during peak enterovirus season. Cerebrospinal fluid pleocytosis was a poor predictor of enterovirus meningitis. The studies were all observational and the evidence was of low quality. CONCLUSIONS Enterovirus polymerase chain reaction testing, independent of cerebrospinal fluid pleocytosis, can reduce length of stay and achieve cost savings, especially during times of high enterovirus prevalence. Additional study is needed to identify subgroups that may achieve greater cost savings from testing to additionally enhance the efficiency of testing.

Abstract
There are no unified protocols governing the management of healthy children with febrile neutropenia in the emergency department (ED). Conservative management is the norm, with admission and empirical broad-spectrum antibiotics prescribed, although viral infections are considered the most frequent etiology. The aim of this study was to describe the clinical outcomes and identified etiologies of unsuspected neutropenia in febrile immunocompetent children assessed in the ED. This was a retrospective study: well-appearing healthy children <18 years old with febrile moderate [absolute neutrophil count (ANC) 500-999 neutrophils ×10(9)/l] or severe (ANC <500 neutrophils ×10(9)/l) neutropenia diagnosed in ED between 2005 and 2013 were included. Patients newly diagnosed with hematologic or oncologic disease were excluded. We included 190 patients: 158 (83.2 %) with moderate and 32(16.8 %) with severe neutropenia. One hundred and one (53.2 %) were admitted; 48(47.5 %) with broad-spectrum antibiotics. The median length of stay was 3 days (IQR 3-5) and the median duration of neutropenia was 6 days (IQR 3-12). An infectious agent was identified in 23(12.1 %); 21 (91.3 %) were viruses. Four (2.1 %) children had a serious bacterial infection (SBI): urinary tract infection and lobar pneumonia (two cases each). All blood cultures performed (144; 75.8 %) were negative. Over the 1-year follow-up, one or several blood tests were performed on 167 patients (87.9 %); two (1.2 %) were diagnosed with autoimmune chronic neutropenia. Previously healthy children with moderate or severe febrile neutropenia have a low risk of SBI and a favorable clinical outcome. Less aggressive management could be carried out in most of them. Although chronic hematological diseases are infrequently diagnosed, serial ANC are necessary to detect them.

Abstract
UNLABELLED Enterovirus (EV) infection is common in infants, but the information with regard to the molecular epidemiology and the associations between types and clinical variables is very scarce. This study includes 195 children <3 months old with fever, attended from March 2010 to December 2012 in an emergency department of a tertiary paediatric hospital in whom EV infection was confirmed by real-time PCR in blood and/or cerebrospinal fluid. Clinical and epidemiological data was prospectively collected. In 152 (77.9 %) patients, EVs could be typed. The most common type was Echovirus-5 (E5; 32, 21.1 %), followed by Echovirus-11 (E11; 18, 11.8 %), Echovirus-21 and Echovirus-25 (E21, E25; 11 each one, 7.2 %) and Coxsackievirus-B4 (CVB4; 6, 6.6 %). The majority of types appeared in spring, but E5 and E25 were found mainly during summer (p < 0.01). E21 was associated with high-grade fever (p < 0.01); E5 with exanthema (p = 0.03) and CVB4 tended to cause meningitis more often than the other types (p = 0.07). CONCLUSION The most common EV types were Echovirus-5 and Echovirus-11. Some significant associations between types and epidemiologic and clinical findings were observed. What is Known-What is New • Enteroviruses cause a normally benign illness in young infants, except in some cases. • The molecular epidemiology of Enterovirus infection is not well known in European countries. • This study describes a large number of infants with Enterovirus infection and shows the seasonality of different types, and their associations with epidemiologic and clinical variables.

Abstract
INTRODUCTION The infectious disease is the main source of care demand in Pediatric Emergency Departments (PED) and is a frequent cause of hospital admission with antibiotics. Our objectives are: 1) to determine the diseases that are seen in PED that required admission with antibiotics; 2) to determine the microbiological methods used and, 3) to analyze the characteristics of the indicated treatment. MATERIAL AND METHODS A prospective multicenter study was conducted in 22 Spanish hospitals. We included patients younger than 18 years seen in PED on day 14 of each month between June 2009 and May 2010 who required hospitalization with systemic antibiotics. Patients admitted to Intensive Care Unit were excluded. RESULTS There were 30,632 consultations in the PED during the study period. A total of 1,446 (4.7%) patients were hospitalized, 395 (27.3%) of them with antibiotics. Ninety-five patients (24.1%) had received antibiotics before admission. Three hundred twenty (81%) children underwent at least one microbiological test, with blood culture (69.9%) and urine culture (30.9%) being the most requested ones. The main diagnoses at admission were pneumonia (29.4%), urinary tract infection (15.4%), and fever without source (12.1%). Twenty five different antibiotics were prescribed, with cefotaxime (27.8%) and amoxicillin-clavulanate (23.4%) being the most prescribed ones. A single antibiotic was prescribed to 80.8% of patients, and parenteral administration was the most indicated (93.7%). CONCLUSIONS Antibiotic therapy was prescribed in one in every 4 patients who required admission to hospital. Pneumonia was the most common source. Blood culture was the most frequent microbiological test requested in the PED. A limited number of beta-lactam antibiotics represented the majority of antibiotic prescriptions.
