RESUMEN

The purpose of the study is to highlight clinical signs that are either suggestive of or against the diagnosis of AHEI to improve diagnosis and management. The medical records of children under 3 years old diagnosed with AHEI were retrospectively reviewed. Clinical data and photographs were reviewed by three independent experts, and the cases were classified as probable, doubtful, or unclear AHEI. Of the 69 cases of children diagnosed with AHEI included in 22 centers, 40 were classified as probable, 22 as doubtful, and 7 as unclear. The median age of patients with probable AHEI was 11 months [IQR 9-15], and they were in overall good condition (n = 33/40, 82.5%). The morphology of the purpura was targetoid in 75% of cases (n = 30/40) and ecchymotic in 70% of cases (n = 28/40) and affected mostly the legs (n = 39/40, 97%), the arms (n = 34/40, 85%), and the face (n = 33/40, 82.5%). Edema was observed in 95% of cases and affected mostly the hands (n = 36/38, 95%) and feet (n = 28/38, 74%). Pruritus was absent in all patients with probable AHEI and described for 6/21 with doubtful AHEI (29%). AHEI was the original diagnosis in only 24 patients (n = 24/40, 60%). The major differential diagnoses were purpura fulminans and urticaria multiforme.  Conclusion: AHEI, which the diagnosis is made on clinical findings, is often misdiagnosed. Purpuric lesions localized on the face/ears, arms/forearms, and thighs/legs with edema of the hands without pruritus in a young child with a good overall condition are highly suggestive of AHEI. What is Known: •Acute hemorrhagic edema of infancy (AHEI) is a cutaneous leukocytoclastic vasculitis affecting children under 3 years old. •Appropriate diagnosis is important to distinguish this benign disease from more serious diseases to avoid investigations and treatments, iatrogenic harm and unnecessary follow-up. What is New: •AHEI is an uncommon disorder often misdiagnosed by pediatricians and dermatologists. •Purpuric lesions localized on the face/ears, arms/forearms, and thighs/legs with edema of the hands without pruritus in an infant with a good overall condition are highly suggestive of AHEI.

RESUMEN

Not having access to language, the infant is deprived of an essential means of communicating its painful experience. The assessment of their pain in the emergency room is therefore quite complex. A study carried out in the paediatric emergency department of the Centre hospitalier intercommunal de Créteil shows that it is possible to improve this aspect thanks, among other things, to continuous training and the presence of experts in children's pain within the team.

RESUMEN

AIM: To assess the prevalence of clinically urgent intracranial pathology (CUIP) in children visiting the emergency department with a complex febrile seizure (CFS). METHODS: Retrospective cohort review. We analysed the visits of patients for a CFS from January 2007 to December 2011 in seven paediatric emergency departments. Our main outcomes were the proportions of CUIP diagnosed between day 0 and 1 and within 30 days after the index visit. RESULTS: From 1 183 487 visits, 839 were for a CFS and 130 (15.5%) of these had a neuroimaging performed within 30 days (CT scan for 75 visits [8.9%], MRI for 30 visits [3.6%] and both for 25 visits [3.0%]). Three CUIP were diagnosed between day 0 and 1 (0.4% [CI-95%: 0.1-1.3]), 5 within 30 days after the index visit (0.7% [CI-95%: 0.2-1.7]) but none among the 630 visits of children presenting with a normal neurological clinical examination (0% [95% CI: 0.0-0.7]), nor among the 468 presenting only with multiple seizure (0% [95% CI: 0.0-1.0]). CONCLUSION: In children with a CFS, CUIP is rare event in the subgroup of children with a normal neurological clinical examination and in those with brief generalised multiple seizures.

RESUMEN

Stroke risk in sickle cell anemia (SCA), predicted by high transcranial Doppler (TCD) velocities, is prevented by transfusions. We present the long-term follow-up of SCA children from the Créteil newborn cohort (1992-2012) detected at risk by TCD and placed on chronic transfusions. Patients with normalized velocities and no stenosis were treated with hydroxyurea, known to decrease anemia and hemolytic rate. Trimestrial Doppler was performed and transfusions restarted immediately in the case of reversion to abnormal velocities. Patients with a genoidentical donor underwent transplant. Abnormal time-averaged maximum mean velocities (TAMMV) ≥200 cm/s were detected in 92 SCA children at a mean age of 3.7 years (range, 1.3-8.3 years). No stroke occurred posttransfusion after a mean follow-up of 6.1 years. Normalization of velocities (TAMMV < 170 cm/s) was observed in 83.5% of patients. Stenosis, present in 27.5% of patients, was associated with the risk of non-normalization (P< .001). Switch from transfusions to hydroxyurea was prescribed for 45 patients, with a mean follow-up of 3.4 years. Reversion, predicted by baseline reticulocyte count ≥400 × 10(9)/L (P< .001), occurred in 28.9% (13/45) patients at the mean age of 7.1 years (range, 4.3-9.5 years). Transplant, performed in 24 patients, allowed transfusions to be safely stopped in all patients and velocities to be normalized in 4 patients who still had abnormal velocities on transfusions. This long-term cohort study shows that transfusions can be stopped not only in transplanted patients but also in a subset of patients switched to hydroxyurea, provided trimestrial Doppler follow-up and immediate restart of transfusions in the case of reversion.

RESUMEN

Objectives: The aim was to describe the epidemiological characteristics of childhood IgA vasculitis (IgAV) defined by the EULAR/PRINTO/Paediatric Rheumatology European Society criteria in a population-based sample from France and ascertain its incidence over 3 years by a four-source capture-recapture analysis. Methods: Cases were prospectively collected in Val de Marne county, a suburb of Paris, with 263 874 residents <15 years old. Children with incident IgAV living in this area from 2012 to 2014 were identified by four sources of case notification (emergency departments, paediatrics departments, private-practice paediatricians and general practitioners). Annual incidence was calculated, and a capture-recapture analysis was used with log-linear modelling to estimate case-finding completeness. Results: We identified 147 incident cases [78 boys; mean age 6.5 (s.d.:2.6) years]. The annual incidence (95% CI) was 18.6 (13.6, 24.5)/100 000 children. Although only 10% of children were exclusively identified by non-hospital sources, the completeness of case finding was 62%, with an undercount-corrected annual incidence (95% CI) of 29.9 (23.7, 37.3)/100 000 children. The annual distribution of diagnoses consistently showed a trough in summer months; 72% of children had infectious symptoms (mainly upper respiratory tract) a few days before IgAV onset; and 23% had a North African background. Conclusion: Our study supports secular and geospatial stability in childhood IgAV incidence and adds further indirect evidence for a possible role of a ubiquitous, non-emerging infectious trigger. Incidence studies from understudied areas are needed to disentangle the role of genetic factors better. Capture-recapture analysis suggests that a substantial portion of IgAV cases may remain unrecognized in epidemiological surveys.

RESUMEN

Early transcranial Doppler (TCD) screening of the Créteil sickle cell anemia (SCA)-newborn cohort, and rapid initiation of transfusion programs, resulted in successful prevention of overt strokes, but a high cumulative risk of silent cerebral infarcts (SCI) remained, suggesting that TCD screening does not identify all patients with SCA at risk for SCI. We hypothesized that episodes of hypoperfusion/hypoxia, as observed during acute chest syndromes or acute anemic events (AAE), and extracranial internal carotid artery (eICA) stenoses, detectable via submandibular Doppler sonography and cervical magnetic resonance angiography (MRA), could also be risk factors for SCI. This study includes 189 stroke-free patients with SCA from the Créteil newborn cohort (1992-2010) followed longitudinally by magnetic resonance imaging/MRA, including cervical MRA at the last assessment. All patients with abnormal TCD and/or intracranial stenoses were placed on a transfusion program. Mean follow-up was 9.9 years (range, 2.2-19.9 years; 1844 patient-years). Annual rates of clinical events were calculated. The cumulative risk for SCI was 39.1% (95% confidence interval [CI], 23.5%-54.7%) by age 18 years, with no plateau. We confirm that baseline hemoglobin level lower than 7 g/dL before age 3 years is a highly significant predictive risk factor for SCI (hazard ratio, 2.97; 95% CI, 1.43-6.17; P = .004). Furthermore, we show that AAE rate (odds ratio, 2.64 per unit increase; 95% CI, 1.09-6.38; P = .031) and isolated eICA stenosis (odds ratio, 3.19; 95% CI, 1.18-8.70; P = .023) are significant and independent risk factors for SCI.

RESUMEN

STUDY OBJECTIVE: We assess the prevalences of bacterial meningitis and herpes simplex virus meningoencephalitis (HSV-ME) in children with a complex febrile seizure and determine these prevalences in the subgroup of children with a clinical examination result not suggestive of meningitis or encephalitis. METHODS: This multicenter retrospective study was conducted in 7 pediatric emergency departments (EDs) in the region of Paris, France. Visits of patients aged 6 months to 5 years for a complex febrile seizure from January 2007 to December 2011 were analyzed. We defined a subgroup of patients whose clinical examination result was not suggestive of meningitis or encephalitis. Bacterial meningitis and HSV-ME were sequentially sought for by analyzing bacteriologic and viral data at the visit, looking for data from a second visit to the hospital after the index visit, and telephoning the child's parents. RESULTS: From a total of 1,183,487 visits in the 7 pediatric EDs, 839 patients presented for a complex febrile seizure, of whom 260 (31.0%) had a lumbar puncture. The outcomes bacterial meningitis and HSV-ME were ascertainable for 715 (85%) and 657 (78.3%) visits, respectively, and we found 5 cases of bacterial meningitis (0.7% [95% confidence interval [CI] 0.2% to 1.6%]) and no HSV-ME (0% [95% CI 0% to 0.6%]). Among the 630 visits of children with a clinical examination result not suggesting meningitis or encephalitis, we found no bacterial meningitis (0% [95% CI 0% to 0.7%]) and no HSV-ME (0% [95% CI 0% to 0.8%]). CONCLUSION: In children with a complex febrile seizure, bacterial meningitis and HSV-ME are unexpected events when the clinical examination after complex febrile seizure is not suggestive of meningitis or encephalitis.

RESUMEN

Transcranial Doppler (TCD) is used to detect children with sickle cell anemia (SCA) who are at risk for stroke, and transfusion programs significantly reduce stroke risk in patients with abnormal TCD. We describe the predictive factors and outcomes of cerebral vasculopathy in the Créteil newborn SCA cohort (n = 217 SS/Sß(0)), who were early and yearly screened with TCD since 1992. Magnetic resonance imaging/magnetic resonance angiography was performed every 2 years after age 5 (or earlier in case of abnormal TCD). A transfusion program was recommended to patients with abnormal TCD and/or stenoses, hydroxyurea to symptomatic patients in absence of macrovasculopathy, and stem cell transplantation to those with human leukocyte antigen-genoidentical donor. Mean follow-up was 7.7 years (1609 patient-years). The cumulative risks by age 18 years were 1.9% (95% confidence interval [95% CI] 0.6%-5.9%) for overt stroke, 29.6% (95% CI 22.8%-38%) for abnormal TCD, which reached a plateau at age 9, whereas they were 22.6% (95% CI 15.0%-33.2%) for stenosis and 37.1% (95% CI 26.3%-50.7%) for silent stroke by age 14. Cumulating all events (stroke, abnormal TCD, stenoses, silent strokes), the cerebral risk by age 14 was 49.9% (95% CI 40.5%-59.3%); the independent predictive factors for cerebral risk were baseline reticulocytes count (hazard ratio 1.003/L × 10(9)/L increase, 95% CI 1.000-1.006; P = .04) and lactate dehydrogenase level (hazard ratio 2.78/1 IU/mL increase, 95% CI1.33-5.81; P = .007). Thus, early TCD screening and intensification therapy allowed the reduction of stroke-risk by age 18 from the previously reported 11% to 1.9%. In contrast, the 50% cumulative cerebral risk suggests the need for more preventive intervention.

RESUMEN

PURPOSE: This study aims to estimate the prevalence of depressive symptoms among adolescents seen in hospital emergency departments and to investigate the concordance between self-reported adolescent depression and parental perceptions of their adolescents' health status. METHOD: A multicentre cross-sectional survey in three emergency departments receiving adolescents in Ile-de-France took place in 2010. All adolescents completed a questionnaire including the Adolescent Depression Rating Scale (ADRS) and a series of questions concerning somatisation and risk behaviours. Parents simultaneously completed a questionnaire collecting their perceptions of their adolescent's health status. RESULTS: The study included 346 adolescents, and of them, 320 were fully analysed. ADRS scores were in the normal range for 70.6 % of the sample (score of <3) (n=226); 19.4 % (n=62) showed moderate depressive symptoms (3 ≤ score<6), and 10.0 %, severe depressive symptoms (score of ≥ 6) (n=32). We observed a wide discrepancy between adolescent depression, determined by a score on a self-administered scale, and parental perceptions of it. CONCLUSION: Routine use of a self-administered questionnaire in emergency units could enable identification of adolescents with moderate or severe depressive symptoms. The present study confirms the importance of increasing parental awareness of their adolescent children's depressive symptoms.

RESUMEN

Lower respiratory tract infections (LRTI) encompass a wide range of clinical syndromes, prominently including bronchiolitis, bronchitis and pneumonia. LRTIs are the second leading cause of antibiotic prescriptions. The vast majority of these infections are due to (or triggered by) viruses and are self-limited diseases. Pneumonia in children is responsible for significant morbidity and mortality worldwide. For clinicians, one of the main difficulties consists in diagnosing pneumonia in febrile children with (or without) cough. The diagnosis is given on the basis of anamnesis, clinical examination and (if necessary) complementary examinations, with chest X-ray or thoracic ultrasound; biological markers are particularly important. Over recent years, since the implementation of PCV13, the bacterial epidemiology of pneumonia and empyema has evolved; involvement in these diseases of pneumococcus has been reduced, and resistance to penicillin has lessened - and remained extremely low. In 2021, according to the National Pneumococcal Reference Center, only 6% of the strains isolated from blood cultures in children are resistant to amoxicillin. The therapeutic choices proposed in this article are in full compliance with the previously published official French recommendations.

RESUMEN

Urinary tract infections are the most frequently proven bacterial infections in pediatrics. The treatment options proposed in this guide are based on recommendations published by the Groupe de Pathologie Infectieuse de Pédiatrique (GPIP-SFP). Except in rare situations (newborns, neutropenia, sepsis), a positive urine dipstick for leukocytes and/or nitrites should precede a urine culture examination and any antibiotic therapy. After rising steadily between 2000 and 2012, the proportion of Escherichia coli strains resistant to extended-spectrum ß-lactamases (E-ESBL) has remained stable over the last ten years (between 7% and 10% in pediatrics). However, in many cases no oral antibiotic is active on E-ESBL leading either to prolonged parenteral treatment, or to use of a non-orthodox combination such as cefixime + clavulanate. With the aim of avoiding penem antibiotics and encouraging outpatient management, this guide favors initial treatment of febrile urinary tract infections (suspected or actual E-ESBL infection), with amikacin. Amikacin remains active against the majority of E-ESBL strains. It could be prescribed as monotherapy for patients in pediatric emergency departments or otherwise hospitalized patients.

RESUMEN

Non-pharmaceutical interventions (NPIs) against coronavirus disease 2019 were implemented in March 2020. These measures were followed by a major impact on viral and non-viral diseases. We aimed to assess the impact of NPI implementation in France on hospitalized community-acquired pneumonia (hCAP) frequency and the clinical and biological characteristics of the remaining cases in children. We performed a quasi-experimental interrupted time-series analysis. Between June 2014 and December 2020, eight pediatric emergency departments throughout France reported prospectively all cases of hCAP in children from age 1 month to 15 years. We estimated the impact on the monthly number of hCAP using segmented linear regression with autoregressive error model. We included 2,972 hCAP cases; 115 occurred during the NPI implementation period. We observed a sharp decrease in the monthly number of hCAP after NPI implementation [-63.0% (95 confidence interval, -86.8 to -39.2%); p < 0.001]. Children with hCAP were significantly older during than before the NPI period (median age, 3.9 vs. 2.3 years; p < 0.0001), and we observed a higher proportion of low inflammatory marker status (43.5 vs. 33.1%; p = 0.02). Furthermore, we observed a trend with a decrease in the proportion of cases with pleural effusion (5.3% during the NPI period vs. 10.9% before the NPI; p = 0.06). NPI implementation during the COVID-19 (coronavirus disease 2019) pandemic led not only to a strong decrease in the number of hCAP cases but also a modification in the clinical profile of children affected, which may reflect a change in pathogens involved.

RESUMEN

Naso-pharyngeal RT-PCR is the gold standard for the diagnosis of COVID-19, but there is a need for rapid and reliable tests. Some validation studies have used frozen aliquots mainly from adults. The aim of this real-life study was to test the performance of a SARS-CoV-2 rapid antigen test (SC2-RAT) in children. Symptomatic patients aged 0 to 17 years were recruited in the emergency department of the University Hospital of Creteil and in primary care pediatric practices from October 10, 2020 for 7 weeks. Each enrolled child had a SARS-CoV-2 RT-PCR test and a SC2-RAT from two distinct nasopharyngeal swabs. Among the 308 patients (mean [SD] age 4.9 [5.3] years), fever was the main symptom (73.4%), with no difference between COVID-19-negative and -positive groups. The prevalence of COVID-19 was 10.7% (95% CI 7.5-14.7). On the whole cohort, the sensitivity and specificity of the SC2-RAT compared to RT-PCR was 87.9% (95% CI 71.8-96.6) and 98.5% (95% CI 96.3-99.6). Considering samples with cycle threshold >25, the sensibility was lower: 63.6% (95% CI 30.8-89.1) and the specificity 99.6% (95% CI 98.0-100.0). The mean delay to obtain an SC2-RAT result was <15 min but was 3.2 h (SD 5.5) for an RT-PCR result. Contact with a COVID-19-positive person was more frequent for COVID-19-positive than -negative patients (n = 21, 61.6%, vs. n = 64, 24.6%; p < 0.01). In real life, SC2-RAT seems reliable for symptomatic children, allowing to detect contagious children.

RESUMEN

Objective(s): Blood cultures (BC), when performed in children seen in the emergency department with community-acquired pneumonia (CAP), are most of the time sterile. We described the diagnostic accuracy of white blood cells (WBC), absolute neutrophils count (ANC), C-reactive protein (CRP), and procalcitonin (PCT) to predict blood culture (BC) result in childhood CAP. Study Design: Secondary analysis of a prospective study carried out in eight pediatric emergency departments (France, 2009-2018), including children (≤15 years) with CAP. Analyses involved univariate comparisons and ROC curves. Results: We included 13,752 children with CAP. BC was positive in 137 (3.6%) of the 3,829 children (mean age 3.7 years) in whom it was performed, mostly with Streptococcus pneumoniae (n = 107). In children with bacteremia, ANC, CRP and PCT levels were higher (median 12,256 vs. 9,251/mm3, 223 vs. 72 mg/L and 8.6 vs. 1.0 ng/mL, respectively; p ≤ 0.002), but WBC levels were not. The area under the ROC curve of PCT (0.73 [95%CI 0.64-0.82]) was significantly higher (p ≤ 0.01) than that of WBC (0.51 [0.43-0.60]) and of ANC (0.55 [0.46-0.64]), but not than that of CRP (0.66 [0.56-0.76]; p = 0.21). CRP and PCT thresholds that provided a sensitivity of at least 90% were 30 mg/L and 0.25 ng/mL, respectively, for a specificity of 25.4 and 23.4%, respectively. CRP and PCT thresholds that provided a specificity of at least 90% were 300 mg/L and 20 ng/mL, respectively, for a sensitivity of 31.3 and 28.9%, respectively. Conclusions: PCT and CRP are the best routinely available predictive biomarkers of bacteremia in childhood CAP.

RESUMEN

OBJECTIVES: To describe the characteristics of children and adolescents affected by an outbreak of Kawasaki-like multisystem inflammatory syndrome and to evaluate a potential temporal association with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. DESIGN: Prospective observational study. SETTING: General paediatric department of a university hospital in Paris, France. PARTICIPANTS: 21 children and adolescents (aged ≤18 years) with features of Kawasaki disease who were admitted to hospital between 27 April and 11 May 2020 and followed up until discharge by 15 May 2020. MAIN OUTCOME MEASURES: The primary outcomes were clinical and biological data, imaging and echocardiographic findings, treatment, and outcomes. Nasopharyngeal swabs were prospectively tested for SARS-CoV-2 using reverse transcription-polymerase chain reaction (RT-PCR) and blood samples were tested for IgG antibodies to the virus. RESULTS: 21 children and adolescents (median age 7.9 (range 3.7-16.6) years) were admitted with features of Kawasaki disease over a 15 day period, with 12 (57%) of African ancestry. 12 (57%) presented with Kawasaki disease shock syndrome and 16 (76%) with myocarditis. 17 (81%) required intensive care support. All 21 patients had noticeable gastrointestinal symptoms during the early stage of illness and high levels of inflammatory markers. 19 (90%) had evidence of recent SARS-CoV-2 infection (positive RT-PCR result in 8/21, positive IgG antibody detection in 19/21). All 21 patients received intravenous immunoglobulin and 10 (48%) also received corticosteroids. The clinical outcome was favourable in all patients. Moderate coronary artery dilations were detected in 5 (24%) of the patients during hospital stay. By 15 May 2020, after 8 (5-17) days of hospital stay, all patients were discharged home. CONCLUSIONS: The ongoing outbreak of Kawasaki-like multisystem inflammatory syndrome among children and adolescents in the Paris area might be related to SARS-CoV-2. In this study an unusually high proportion of the affected children and adolescents had gastrointestinal symptoms, Kawasaki disease shock syndrome, and were of African ancestry.

RESUMEN

This prospective observational study sought to ascertain clinical and laboratory parameters associated with the development of acute chest syndrome (ACS) during vaso-occlusive episodes (VOE) in children with sickle cell disease (SCD). It was performed at the pediatric department of the university Intercommunal Créteil hospital. All children with SCD (all sickle genotypes) consecutively admitted from November 2013 to December 2016 for painful VOEs and no evidence of ACS were included. Clinical and laboratory parameters collected at admission and within 48 h after admission were compared for children in whom ACS developed or not. Variables that were statistically significant on univariate analysis or considered to be clinically relevant were included in a multivariable model to ascertain the risk factors associated with the development of ACS during a VOE. The variables retained in the multivariate model were used to construct a predictive score for ACS. For each included child and during the study period, only data from the first VOE and/or the first ACS were analyzed. Among 191 hospitalizations for painful VOEs, for 176 children with SCD, ACS developed in 35 during hospitalization. Mean hospital stay was longer for children with ACS versus VOEs alone (7.6 (±2.3) vs. 3.3 (±1.8) days, p < 0.0001), and all children with ACS versus 28/156 (17.9%) with VOEs alone received red blood cell transfusion (p < 0.0001). The multivariate model retained pain score (≥9/10), pain localization (abdominal or spinal pain or involving more than two limbs), and high reticulocyte (≥260 × 109/L) and neutrophil (>10 × 109/L) counts, at admission, as independently associated with ACS development. The area under the receiver operating characteristic curve for the ACS predictive score was 0.82 (95% CI: 0.74-0.89), and the negative predictive value was 97.7%. The evolution profiles during the first 48 h differed between children with ACS and VOEs alone, with a more rapid decline of pain score and leucocytosis in children with VOEs. Clinical and laboratory measurements at admission may be simple parameters to identify children with increased risk of ACS development during VOEs and to facilitate early diagnosis of this respiratory complication. Also, the persistent elevation of leukocyte count on day 2 may be considered a sign of evolving ACS.

RESUMEN

Importance: In several countries, 5 years after 13-valent pneumococcal conjugate vaccine (PCV13) implementation, serotype replacement has been reported for invasive pneumococcal disease, which raises concerns about the long-term outcome of PCV13 implementation. The long-term effect of vaccination on community-acquired pneumonia (CAP) remains unknown. Objective: To assess the long-term outcome of PCV13 implementation on CAP in children. Design, Setting, and Participants: This quasi-experimental, population-based, interrupted time-series analysis was based on a prospective multicenter study conducted from June 2009 to May 2017 in 8 French pediatric emergency departments. All patients 15 years and younger with chest radiography-confirmed CAP were included. Exposures: Community-acquired pneumonia. Main Outcomes and Measures: The number of CAP cases per 1000 pediatric emergency department visits over time, analyzed using a segmented regression model, adjusted for influenza-like illness syndromes. Results: We enrolled 12 587 children with CAP, including 673 cases of CAP with pleural effusion (5.3%), 4273 cases of CAP requiring hospitalization (33.9%), 2379 cases of CAP with high inflammatory biomarkers (18.9%), and 221 cases of proven pneumococcal CAP (1.8%). The implementation of PCV13 in 2010 was followed by a sharp decrease in the frequency of CAP (-0.8% per month [95% CI, -1.0% to -0.5% per month]), from 6.3 to 3.5 cases of CAP per 1000 pediatric emergency department visits until May 2014, then a slight increase since June 2014 (0.9% per month [95% CI, 0.4%-1.4% per month]), until 3.8 cases of CAP per 1000 pediatric emergency department visits in May 2017. There were marked immediate decreases in cases of CAP with pleural effusion (-48% [95% CI, -84% to -12%]), CAP requiring hospitalization (-30% [95% CI, -56% to -5%]), and CAP with high inflammatory biomarkers (-30% [95% CI, -54% to -6%]), without any rebound thereafter. Conclusions and Relevance: The changes associated with PCV13 use 7 years after implementation remain substantial, especially for CAP with pleural effusion, CAP requiring hospitalization, and CAP with high inflammatory biomarkers. Emerging non-PCV13 serotypes may be less likely involved in severe CAP than invasive pneumococcal disease.

RESUMEN

OBJECTIVES: To assess the management of febrile urinary-tract infection (FUTIs) due to extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-E) in children, the Pediatric Infectious Diseases Group of the French Pediatric Society set up an active surveillance network in pediatric centers across France in 2014. MATERIALS AND METHODS: We prospectively analysed data from 2014 to 2016 for all children < 18 years old who received antibiotic treatment for FUTI due to ESBL-E in 24 pediatric centers. Baseline demographic, clinical features, microbiological data and antimicrobials prescribed were collected. RESULTS: 301 children were enrolled in this study. The median age was 1 year (IQR 0.02-17.9) and 44.5% were male. These infections occurred in children with history of UTIs (27.3%) and urinary malformations (32.6%). Recent antibiotic use was the main associated factor for FUTIs due to ESBL-E, followed by a previous hospitalization and travel history. Before drug susceptibility testing (DST), third-generation cephalosporins (3GC) PO/IV were the most-prescribed antibiotics (75.5%). Only 13% and 24% of children received amikacine alone for empirical or definitive therapy, respectively, whereas 88.7% of children had isolates susceptible to amikacin. In all, 23.2% of children received carbapenems in empirical and/or definitive therapy. Cotrimoxazole (24.5%), ciprofloxacin (15.6%) and non-orthodox clavulanate-cefixime combination (31.3%) were the most frequently prescribed oral options after obtaining the DST. The time to apyrexia and length of hospital stay did not differ with or without effective empirical therapy. CONCLUSIONS: We believe that amikacin should increasingly take on a key role in the choice of definitive therapy of FUTI due to ESBL-E in children by avoiding the use of carbapenems.

RESUMEN

We report a retrospective monocentric descriptive study performed in CHI Creteil for 20 months to describe the management and outcome of amikacin monotherapy as an alternative to third-generation cephalosporins for empiric treatment of febrile urinary tract infection (FUTI) in children. Data were analyzed for 151 children, and 90 selected cases were classified as certain or highly probable FUTI. Escherichia coli infection was found in 89 cases. In all patients, fever was resolved within 72 hours after beginning amikacin treatment. Only 5.3% of children were febrile after 48 hours. The mean amikacin treatment duration was 3.05 ± 0.13 days before oral treatment began (guided by antibiotic susceptibility testing). Amikacin monotherapy seems effective for the initial management of FUTI in children.

RESUMEN

BACKGROUND: Many countries have observed an early and strong impact of implementation of the 13-valent pneumococcal conjugate vaccine (PCV13) on community-acquired pneumonia (CAP). High levels of C-reactive protein (CRP) and procalcitonin (PCT) are considered biomarkers of bacterial infection (particularly infection due to pneumococcus); therefore, PCV13 implementation should have different effectiveness on CAP depending on the levels of these two biomarkers. To demonstrate this assumption, we analyzed the evolution of number of CAP cases seen in pediatric emergency departments in France after PCV13 implementation (in 2010) by levels of these two biomarkers. METHODS: From June 2009 to May 2015, 8 pediatric emergency units prospectively enrolled all children (1month to 15years) with radiologically confirmed CAP. RESULTS: A cohort of 9586 children with CAP was enrolled (median age 3years). CAP with pleural effusion (PE-CAP) and proven pneumococcal pneumonia (PP-CAP) accounted for 5.5% and 2.0% of cases. During the study period, the number of cases of overall CAP decreased by 25.4%, hospitalized CAP by 30.5%, PE-CAP by 63.4%, CAP with CRP level≥100mg/L by 50.9%, CAP with PCT level≥4ng/L by 60.4% and PP-CAP by 86.4%. We found no change in number of cases of CAP with low levels of CRP (<20 or <40mg/L) or PCT (<0.5ng/mL). The number of cases of CAP overall increased (20.0%) in the last year of the study as compared with the preceeding year but not cases with CRP level≥100mg/L and/or PCT level≥4ng/mL. CONCLUSION: PCV13 implementation has had a strong impact on number of CAP cases with high levels of CRP and/or PCT in children but no impact on that with low levels of these two biomarkers. Five years after PCV13 implementation, a sustained reduction in CAP cases is observed.
