The Impact of Respiratory Symptoms on the Risk of Serious Bacterial Infection in Febrile Infants < 60 Days Old. J Clin Med 2023; 12:4636. [PMID: 37510751 PMCID: PMC10380775 DOI: 10.3390/jcm12144636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 07/09/2023] [Accepted: 07/10/2023] [Indexed: 07/30/2023] Open
Abstract
OBJECTIVES We aimed to evaluate the impact of respiratory symptoms and positive viral testing on the risk of serious bacterial infections (SBIs). METHODS A retrospective study was conducted that included infants (0-60 days) presenting with a fever between 2001 and 2022 at a tertiary hospital in northern Israel. Demographic, clinical, and laboratory parameters were collected, and risk factors for SBIs were analyzed. RESULTS Data from a total of 3106 infants, including data from blood, urine, and CSF cultures, were obtained in 96.6%, 89%, and 29% of cases, respectively. A fever without respiratory symptoms (fever only) was present in 1312 infants, while 1794 had a fever and respiratory symptoms-427 were positive for a respiratory virus (virus+), 759 tested negative (virus-), and 608 were not tested. The SBI rate was 5.1% vs. 7.5% in the fever-and-respiratory group vs. the fever-only group (p = 0.004, OR = 0.65 (95% CI = 0.49-0.88)) and 2.8% vs. 7% in the virus+ vs. virus- group (p = 0.002, OR = 0.385, (95% CI = 0.203-0.728)). The male gender, an age < 1 month, leukocytosis > 15 × 109/L, or a CRP > 2 mg/dL increased the risk of SBIs. Respiratory symptoms or a confirmed viral infection reduced the risk of SBIs in the presence of the above risk factors. CONCLUSIONS Respiratory symptoms and a positive viral test decreased the risk of SBIs. Combining rapid viral testing with clinical variables may identify low-risk infants. Despite the relatively low risk of SBIs in individuals with viral infections, conducting prospective studies remains essential for accurately predicting the occurrence of these potentially life-threatening infections.

Non-polio enterovirus aseptic meningitis in infants up to three months of age, the bacterial mask of viral disease: A retrospective cohort study. J Clin Virol 2023; 162:105427. [PMID: 37001461 DOI: 10.1016/j.jcv.2023.105427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 03/11/2023] [Accepted: 03/19/2023] [Indexed: 03/30/2023]
Abstract
BACKGROUND Non-polio enterovirus aseptic meningitis (NPE-AM) is a self-limiting illness that can mimic serious bacterial infection (SBI) in infants during their first months of life. OBJECTIVES To compare the clinical features of febrile infants diagnosed with NPE-AM with those of infants who had SBI or non-bacterial infection (NBI). STUDY DESIGN A systematic series of febrile infants < 3-months-old hospitalized between 2010 and 2019 with febrile illness in a tertiary hospital. Clinical and laboratory data were compared between the three groups. RESULTS Overall 1278 infants were included; 207 (16.2%) had NPE-AM, 210 (16.4%) SBI and 861 (67.4%) NBI. The median age was 34 (IQR: 21.5-51.7) days. NPE-AM was documented in 25% of infants < 29 days and 9.9% of infants aged 29-90 days. Infants with NPE-AM or SBI had fever >39°C more frequently, 24.2% and 17.1% compared with 10% in infants with NBI (p < 0.001). Fever duration ≥ 2 days was reported in 3.4% of infants with NPE-AM vs 18.6% in SBI and 26.3% in NBI (p < 0001); rash occurred in 37.7% in NPE-AM compared to 4.6% in NBI and 5.7% in SBI (p < 0.001). The mean white blood count, C-reactive protein and absolute neutrophil count were significantly lower in infants with NPE-AM compared to infants with the SBI (p < 0.001) and similar to the means in infants with NBI (p = 0.848, 0.098 and 0.764 respectively). A high proportion of bloody tap 346/784 (53.1%) was detected. Infants with NPE-AM were more likely to be treated with antibiotics than infants with NBIs (88.9% vs 50.7%, p < 0.001), similarly to infants with SBIs (p = 0.571). CONCLUSIONS The clinical presentation of infants with NPE-AM that could mimic bacterial infection and the high rate of bloody taps may lead to more hospital admissions and antibiotic prescriptions. Rapid molecular testing for detection of NPE may be of additional value in the evaluation of febrile infants.

Predictive factors for focal disease in human brucellosis, an observational cohort study. Eur J Clin Microbiol Infect Dis 2023; 42:221-226. [PMID: 36547765 DOI: 10.1007/s10096-022-04541-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Accepted: 12/14/2022] [Indexed: 12/24/2022]
Abstract
This retrospective cohort study aimed to identify predictors for focal disease in human brucellosis. The study included patients with brucellosis diagnosed between January 2000 and December 2021. Overall, 247 patients were identified. Focal disease was diagnosed in 64 (25.9%) patients. The most common focal infection was bone and joint in 56 patients (23.4%). Disease duration > 14 days was significantly associated with focal illness [OR = 2.2 (1.08-4.47), p = 0.030], although febrile illness was inversely associated with focal illness this did not reach statistical significance [OR = 0.46 (0.21-1.00), p = 0.050]. Focal brucellosis should be suspected in patients with prolonged illness.

Abstract
OBJECTIVES We studied profile of the bloodstream infections (BSI) in the pediatric intensive care unit (PICU) and identified predictors of mortality. METHODS The study collected data from hospital records for children younger than 18-years who developed BSI during their PICU stay between 2014 and 2019. RESULTS In 114 patients, 136 PICU-acquired BSIs with 152 pathogens were documented. The incidence of BSI was 47.12/1,000 PICU admissions and 7.95/1000 PICU hospital days. Gram-negative rods accounted for 75% of isolates, Gram-positive cocci accounted for 21.7% of isolates, and fungi accounted for 3.3% of isolated pathogens. ICU mortality was observed in 25 (21.9%) patients with a BSI compared to 94 (3.1%) patients without a BSI (P<0.001). Hemodynamic instability (P=0.014, OR 4.10, CI 1.33-12.66), higher blood urea nitrogen (BUN) (P=0.044), and lower albumin levels (P=0.029) were associated with increased risk of ICU mortality. CONCLUSION BSI in the PICU is associated with increased mortality. Early identification and management of risk factors independently associated with poor clinical outcomes in these patients should be aimed to ensure improved survival.

The Role of Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in the Management of Brucellosis: An Observational Cohort Study. Open Forum Infect Dis 2023; 10:ofac704. [PMID: 36686638 PMCID: PMC9846188 DOI: 10.1093/ofid/ofac704] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 12/30/2022] [Indexed: 01/03/2023] Open
Abstract
Background Diagnosis of focal infection in brucellosis is important to direct optimal treatment. Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) may be helpful in this aspect. Methods The clinical and imaging data of all patients with brucellosis, who underwent FDG PET/CT as part of the investigation in Rambam Health Care Campus, where FDG PET/CT became the recommended imaging modality for suspected focal infection in brucellosis since 2016, were analyzed retrospectively. The detection of focal infection as well as management modification before and after FDG PET/CT were recorded. Results FDG PET/CT was performed in 30 episodes of brucellosis occurring in 27 patients: 20 primary episodes and 10 suspected relapse episodes. The mean age of the patients was 50 ± 15.07 years. Focal disease was diagnosed in 18 of 30 (60%) episodes, of which 8 (26.6%) were diagnosed for the first time by FDG PET/CT, all of whom had spinal infection, with a concomitant additional focus in 5. Overall, multifocal disease was diagnosed in 10 of 18 (55.5%) of patients with focal disease. Management modification following FDG PET/CT was recorded in 17 of 30 (56.6%) episodes, mainly by treatment extension in spinal infection and withholding treatment in patients with suspected relapse but no evidence of active disease by FDG PET/CT. Conclusions FDG PET/CT was found to be helpful in the diagnosis of focal infection in brucellosis. Multifocal disease seems more prevalent than previously described. The clinical impact of adding FDG PET/CT to the diagnostic workup of brucellosis should be evaluated in future studies.

Evaluation of Pediatric Screening for Resistant Pathogens in an Israeli Tertiary Center. THE ISRAEL MEDICAL ASSOCIATION JOURNAL : IMAJ 2022; 25:836-841. [PMID: 36573780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 12/29/2022]
Abstract
BACKGROUND Antibiotic resistance is a worldwide problem associated with increased morbidity and mortality. OBJECTIVES To evaluate multidrug resistant (MDR) bacteria carriage in selected populations. METHODS Data were collected from all patients under 18 years who met our internal guidelines from 2015-2016. They were screened for carbapenem-resistant Enterobacteriaceae (CRE), extended spectrum beta-actamase (ESBL), methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococci (VRE). Indications for screening were non-resident non-Israeli patients (from the Palestinian Authority, Syria, and foreign patients), internal transfers from intensive care units, admission to high-risk departments, recent carriage of MDR bacteria, transfer from other hospitals, and recent hospitalization. Data were analyzed for MDR bacteria from at least one screening site (rectal, nasal, axillary, groin, throat). All data were analyzed per patient and per sample. RESULTS During the study period 185/2632 positive screening sets (7%) were obtained from 725 patients. Of these, 165 patients (22.7%) were positive for at least one pathogen. Significantly fewer Israeli residents (120/615, 19.5%) tested positive compared to non-Israeli residents (45/110, 40.9%; P < 0.001). Past MDR bacteria carriage was the only significant screening indication (25/61, 41%; P < 0.001). CRE, VRE, MRSA, and ESBL prevalence rates were 0.6% (5/771), 0.5% (3/560) 0.5%, 4.2% (37/888), and 33.7% (139/413), respectively. Among non-ESBL carriers, MRSA was predominant with 38 positive cultures (n=34). CONCLUSIONS Non-Israeli non-residents and patients with previous positive MDR screening are at higher risk for MDR bacteria. Indications used to identify high-risk patients for drug resistant pathogens were efficacious. More effort is needed to reduce excessive sampling.

Abstract
BACKGROUND Apart from age and underlying disease, predictors of adverse outcome in children hospitalized with influenza are poorly understood. OBJECTIVES Our goal is to determine clinical and laboratory predictors that help identify children at increased risk for an unfavorable course and identify differences in clinical presentation between serotypes. STUDY DESIGN A retrospective, observational cohort study conducted at the Rambam Healthcare Campus in Haifa. We analyzed data from electronic records of children < 18 years with influenza A or B infection hospitalized between 2009 and 2020. Multivariate regression analyses were used to identify predictors of unfavorable outcome, defined as mortality, ICU admission, intubation, prolonged length of stay, or bacterial coinfection. RESULTS A total of 1077 children were included, of whom 54% were male. The median age was 2.5 years. Influenza A was detected in 797 (74%) and influenza B in 286 (26%) of the cases. Children with influenza A were younger (OR 2.51, 95%CI 1.90-3.33), more likely to have oxygen desaturation <90% (OR 2.44, 95%CI 1.23-4.83) and an elevated CRP>5 mg/dL on admission (OR 2.67, 95% CI 1.63-4.37). In multivariate analyses, oxygen desaturation <90% and CRP > 5 mg/dL at admission had an 11.1 and 4-fold increased risk of unfavorable outcome, respectively, in addition to a 3.1 and 1.6-fold increased risk in the presence of underlying condition or influenza A serotype infection, respectively. CONCLUSIONS Data available on admission can help identify children hospitalized with influenza who are at increased risk for complications and unfavorable outcome, encouraging aggressive treatment and care.

Abstract
AIM We examined community and hospital-acquired bacteraemia, namely bloodstream infections or meningitis, and looked at the clinical features and outcomes of cases. METHODS The study comprised infants under 3 months of age, who were admitted to a tertiary referral centre in northern Israel with bacteraemia from 2010-2019. Causative pathogens, antibiotic susceptibility and mortality were retrospectively recorded. RESULTS We identified 314 infants, 325 episodes of bacteraemia and 344 pathogens. Meningitis was identified in 22 (7.0%) infants. Hospital-acquired bacteraemia accounted for 84.8% of the 325 episodes. Coagulase-negative staphylococci (33.9%) was the most prevalent pathogen in the hospital-acquired cases, while Escherichia coli (37.2%) dominated the community-acquired cases. The susceptibility of Gram-negative early-onset sepsis cases to ampicillin-gentamicin or ampicillin-cefotaxime was 96% and 94.7% for hospital-acquired cases and 91.7% and 88% for community-acquired cases, respectively. Susceptibility to piperacillin-tazobactam or amikacin in late-onset sepsis were 92.8% and 98%, respectively, in hospital-acquired cases. The 30-day mortality was 5.7% in infants with hospital-acquired cases. Risk factors were Arab ethnicity (p < 0.028), haemodynamic instability (<0.001) and Gram-negative sepsis (0.043). CONCLUSION Most cases of bacteraemia were acquired during hospitalisation and these accounted for the majority of the deaths. Resistance to standard antibiotic regimens was rare.

Abstract
INTRODUCTION Community acquired pneumonia (CAP) is a leading cause of morbidity in children, despite advances in health care and anti-pneumococcal vaccine. Complicated pneumonia accounts for a significant burden with prolonged hospitalization. Finding risk factors for complicated pneumonia may help in tailoring management. We aimed to identify risk factors for developing complicated pneumonia and need for intervention. METHODS A retrospective single tertiary center study. Children admitted with a diagnosis of CAP and/or complicated pneumonia (parapneumonic effusion, empyema, necrotizing pneumonia, and lung abscess) on January 2001-March 2020 were included. Demographic, clinical, and laboratory parameters were collected using MDclone, a data acquisition tool. Risk factors for complicated pneumonia (on admission or during hospitalization) and risk for intervention were analyzed. RESULTS A total of 6778 children with pneumonia were included; 323 arrived at the Emergency Department with complicated pneumonia while 232 developed a complication during hospitalization. Risk factors for complicated pneumonia (on admission or during hospitalization) were Arab ethnicity, cardiac disease, increased age, and CRP and low O2 Sat (OR = 2.236 p < .001, OR = 4.376 p < .001, OR = 1.131 p < .001, OR = 1.065 p < .001 and OR = 0.959 p = .029, respectively). O2 Sat was lower, while fever and CRP were higher in patients with complicated pneumonia requiring intervention. CONCLUSIONS Identifying children at risk for complicated pneumonia may help in decision-making in the Emergency Department and during hospitalization. The increased risk of the Arab population for complicated pneumonia requires further understanding. Addressing the underlying socioeconomic and ethnic health inequities may help to decrease the disease burden in this population.

Abstract
This study aims to describe the microbiology and susceptibility profile of the intraperitoneal flora in complicated appendicitis. It is a retrospective cohort study including children < 18-year-old with pathologically confirmed appendicitis, from 2007 to 2017. It included 1466 children. Intraperitoneal samples were obtained from 655 (44.7%) patients, and 201 (30.7%) had positive culture with 395 pathogens. Gram-negative rods comprised 67.6%, Gram-positive cocci 21.5%, and anaerobes 10.9% of the isolates. Gram-positive cocci were detected in 67 (37.8%) patients. Milleri group Streptococci was the most frequently isolated Gram-positive (44.7%). The proportional rate of Milleri group Streptococci from Gram-positive cocci increased from 9.5 to 56.3% (P < 0.001, OR 12.214). Patients with Gram-positive cocci had longer hospital stay (mean 9.36 + 6.385 vs 7.72 + 4.582, P = 0.036, (CI -3.165, -0.105)) and more complicated disease (89.5% vs 78.4%, P = 0.045, OR 2.342). Patients with Milleri group Streptococci isolates readmitted more frequently (26.5% vs 13.2%, P = 0.05, OR 2.37). Resistance to amoxicillin-clavulanate, gentamicin, ceftazidime, piperacillin-tazobactam, and amikacin were detected in 29.1%, 6.5%, 2.3%, 1.2%, and 0.7% of the Gram-negative rods, respectively.Conclusion: The rates of Gram-positive cocci and particularly Milleri group Streptococci in peritoneal fluid are increasing. More complicated disease and longer hospital stay in Gram-positive cocci and higher readmission rate in Milleri group Streptococci. These emphasize the role of anti-Gram-positive antimicrobials. What is known: • Gram-negative rods are the main isolates in complicated appendicitis. • The choice of antibiotic regimen is an unsettled issue due to resistance. What is new: • Increased rate of Gram-positive cocci and Milleri group Streptococci. • More complicated disease, longer hospital stay, and higher readmission rate.

Abstract
Inherited liver diseases may present in infancy as cholestatic jaundice progressing to severe hepatic dysfunction. Congenital cytomegalovirus (cCMV) infection may initially involve the liver, yet in otherwise healthy hosts rarely leads to long-term hepatic disease. We report a series of three patients, diagnosed with hereditary liver diseases: progressive familial intrahepatic cholestasis (PFIC) type IV, alpha 1 anti-trypsin deficiency (A1ATD) and Alagille syndrome (ALGS), who were also diagnosed with cCMV infection. All patients were treated with valgancilovir for symptomatic cCMV infection (6-12 months), followed by suppressive dosing in the 2 patients with PFIC and A1ATD. Following 15-24 months of follow-up - the patients with PFIC and A1ATD developed severe liver failure, and the third had ongoing cholestatic disease with stable synthetic function. We propose a significant contribution of cCMV infection to the course of the inherited primary disease, possibly leading to further compromise of the liver. We recommend screening patients with inherited liver disease for cCMV, and considering anti-viral treatment with valganciclovir to delay hepatic disease progression.

Abstract
Varicella live attenuated vaccine led to a significant reduction in morbidity and mortality from varicella zoster disease. Vaccine adverse effects are mostly mild. Immunosuppression is the main risk factor for severe varicella. Risk factors for disease following vaccination are less studied. We report a 12-month-old infant with no T-cell immunodeficiency who developed severe varicella infection by vaccine strain.

Abstract
AIM Incidences of Staphylococcus aureus bacteraemia (SAB) in Israeli children are unknown. The characteristics of SAB in children have not been evaluated. METHODS SAB from children aged ≤18 years old, admitted to a tertiary hospital in Israel during 2002-2015, were included. The proportional rate of SAB was calculated per 1000 admissions. SAB were classified as community acquired (CA), hospital acquired (HA) and healthcare related (HCR). Patients' characteristics, antibiotic susceptibility and outcomes were assessed in each group. RESULTS The rate of SAB was stable, 1.48 per 1000 admissions. HA, CA and HCR-SAB comprised 53%, 25% and 22%, respectively. Only 27/185 (14.6%) were caused by methicillin-resistant S aureus (MRSA): 22%, 6% and 5% of HA, CA and HCR-SAB, respectively. Central venous catheter, recent surgery, immunodeficiency and age <6 years were the main risk factors for HA and HCR-SAB (adjusted OR: 68.9, 7.5, 5.8 and 5.5, respectively). Treatment duration for CA was >21 days: and for HA and HCR, 14-20 days. All-cause in-hospital mortality and 30-day mortality were documented in 10 (5%) and 3 (2%) episodes, respectively. CONCLUSION The rate of SAB; the proportions of CA, HA and HCR-SAB; and the proportion of MRSA was stable over the years. MRSA was mainly in HA-SAB. Thirty-day mortality was rare.

Abstract
Studies of this condition, which is underestimated in children, will aid in its diagnosis and treatment. Q fever osteoarticular infection in children is an underestimated disease. We report 3 cases of Q fever osteomyelitis in children and review all cases reported in the literature through March 2018. A high index of suspicion is encouraged in cases of an unusual manifestation, prolonged course, relapsing symptoms, nonresolving or slowly resolving osteomyelitis, culture-negative osteomyelitis, or bone histopathology demonstrating granulomatous changes. Urban residence or lack of direct exposure to animals does not rule out infection. Diagnosis usually requires use of newer diagnostic modalities. Optimal antimicrobial therapy has not been well established; some case-patients may improve spontaneously or during treatment with a β-lactam. The etiology of treatment failure and relapse is not well understood, and tools for follow-up are lacking. Clinicians should be aware of these infections in children to guide optimal treatment, including choice of antimicrobial drugs, duration of therapy, and methods of monitoring response to treatment..

Nationwide epidemiology of early-onset sepsis in Israel 2010-2015, time to re-evaluate empiric treatment. Acta Paediatr 2019; 108:2192-2198. [PMID: 31168848 DOI: 10.1111/apa.14889] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Revised: 05/27/2019] [Accepted: 06/04/2019] [Indexed: 01/25/2023]
Abstract
AIM Early-onset neonatal sepsis (EOS) may lead to significant morbidity and mortality, yet the recommended antimicrobials have not changed for many years. We aimed to optimise EOS treatment by examining EOS pathogens, resistance rates and resistance risk factors. METHODS A retrospective, nationwide cohort study analysing 2010-2015 EOS data in Israel. RESULTS The 21 participating centres constitute 92% of the total birth cohort (around 180 000 live births/year). Of 549 EOS neonates (0.57/1000 live births), 306 (56%) and 243 (44%) were full-term and preterm, respectively (0.35 vs. 2.94 per/1000 live births). Gram-negative pathogens predominated, especially in preterms. Escherichia coli and Streptococcus agalactiae were most common pathogens (0.2 and 0.19 per 1000 live births, respectively). In 277 Gram-negatives, 16%, 14%, 8% and 3% were gentamicin-resistant, extended-spectrum beta-lactamase (ESBL)-positive, gentamicin-resistant and ESBL-positive, and amikacin-resistant, respectively; preterms had higher resistance rates. No risk factors for antimicrobial resistance were identified. Mortality was reported in 21% of Gram-negative EOS versus 7% of Gram-positive EOS [OR 3.4 (95% CI 1.8-6.2), p < 0.01]. CONCLUSION In this nationwide study, EOS was caused predominantly by Gram-negatives, with high gentamicin resistance and ESBL phenotype rates, without identifiable resistance risk factors. As EOS is life-threatening, modification of empiric therapy for amikacin-based regimens should be considered, mainly in preterms.

Abstract
BACKGROUND Adenovirus is responsible for 2-7% of childhood viral respiratory infections, 5-11% of viral pneumonia and bronchiolitis. Most are self-limited but may cause severe respiratory infection. OBJECTIVES To describe adenovirus respiratory infection in immunocompetent children in a pediatric intensive care unit (PICU). METHODS Children with adenovirus respiratory infection in our PICU from 2007 to 2016 were included. Data were retrospectively retrieved, including background, clinical manifestation, and treatment. Adenovirus was diagnosed by polymerase chain reaction, immune fluorescence, or both. RESULTS Of 9397 samples, 956 were positive for adenovirus in children hospitalized during the study period. In total, 49 patients (aged 2 months-11.5 years) were admitted to our PICU, five were immunocompromised and excluded from the study, 19/44 (43%) were referred from other hospitals. Twenty-eight (64%) had underlying conditions, 66% had fever and cough, 11% had conjunctivitis, and 34% received antibiotics before admission. White blood cell counts ranged from 790 to 34,300 (mean 14,600) and 36% had counts above 15,000. Chest X-ray was consistent with viral infection in 77% of patients and normal in three (13.6%). Viral co-infection was found in 9 patients, 7 had presumed bacterial super-infection, and 27 (61.4%) needed mechanical ventilation. Two patients received cidofovir, 33 (75%) steroids, and 37 (84 %) antibiotics. Four patients died. CONCLUSIONS Adenovirus respiratory infection may cause severe disease necessitating PICU admission and mechanical ventilation, mostly in patients with underlying conditions. Many patients received steroids and antibiotics, which may be unnecessary. Mortality was 9%, mainly among young infants and those with underlying conditions.

Abstract
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a challenging nosocomial pathogen in the last 50 years. OBJECTIVES To describe an investigation and containment of an MRSA outbreak in a neonatal intensive care unit (NICU). METHODS Our NICU is a 25-bed level III unit. Almost 540 neonates are admitted yearly. The index case was an 8 day old term baby. MRSA was isolated from his conjunctiva. Immediate infection control measures were instituted, including separation of MRSA+ carriers, strict isolation, separate nursing teams, and screening of all infants for MRSA. Healthcare workers and parents of positive cases were screened and re-educated in infection control measures. New admissions were accepted to a clean room and visiting was restricted. MRSA isolates were collected for molecular testing. RESULTS MRSA was isolated from five infants by nasal and rectal swabs, including the index case. Screening of healthcare workers and families was negative. Two MRSA+ patients already known in the pediatric intensive care unit (PICU) located near the NICU were suspected of being the source. All NICU isolates were identical by pulsed-field gel electrophoresis but were different from the two PICU isolates. The NICU and one of the PICU isolates were defined as ST-5 strain by multilocus sequence typing. One PICU isolate was ST-627. All NICU isolates were Panton-Valentine leukocidin negative and SCCmec type IV. No further cases were detected, and no active infections occurred. CONCLUSIONS A strict infection control policy and active screening are essential in aborting outbreaks of MRSA in the NICU.

Abstract
Uveitis is an inflammatory disease of the intraocular structures involving various parts of the eye. Delays in diagnosis or treatment can lead to severe and irreversible vision loss. There are many causes leading to the development of uveitis, including: infectious, inflammatory, autoimmune and idiopathic sources. Uveitis is rarer in children than in other age groups and its diagnosis is challenging and treatment is complex. This disease might present at later stages after vision damage is already present. Uveitis and decreased vision may be the presenting symptom and/or sign of various inflammatory diseases, which would become fully expressed many years later. This review is limited to uveitis of infectious origin in the pediatric population, with a focus on the most common pathogens, based on the main anatomical sections involved in this disease. Moreover, we will clarify existing diagnostic tools and treatment options relevant for each underlying cause.

Abstract
INTRODUCTION Antibiotic stewardship programs (ASP) are designed to optimize antibiotic use in hospitals. Antibiotic consumption is one of the measures assessing the effects of ASPs. AIMS To evaluate the effect of an ASP on antibiotic consumption in our hospital and compare it to hospitals in Israel and worldwide. METHODS Between October 2012 and March 2013 an ASP was implemented in Rambam Hospital. The program included educational activities, publication of local guidelines for empirical antibiotic treatment, structured infectious diseases consultations, pre-authorization antibiotic restrictions and stop orders. We compared antibacterial antibiotic consumption in defined daily doses (DDD)/100 hospital days (HD) between the periods before (1/2010-3/2013) and after (4/2013-9/2014) implementing the ASP. The study was conducted in the medical departments, hematology, the intensive care unit (ICU) and all pediatric wards. RESULTS Total antibiotic consumption before implementing the ASP was 96±11.2 DDD/100 HD in medical departments, 186.4±42.8 in the ICU and 185.5±59 in hematology; all values were higher than the worldwide-reported averages for these departments. Following the ASP, total antibiotic consumption decreased by 12% (p=0.008) in the medical departments and by 26% (p=0.002) in hematology, mostly due to reductions in non-restricted antibiotics. No significant changes were observed overall in the ICU and in pediatric wards. There was a significant reduction in consumption of vancomycin and carbapenems in all settings, the latter was reduced to nearly half. Amikacin use quadrupled in the medical departments. CONCLUSIONS Implementation of an ASP lead to a reduction in non-restricted and restricted antibiotic consumption, especially carbapenems.

Abstract
BACKGROUND Acute bronchiolitis in infancy is considered a risk factor for recurrent wheezing episodes in childhood. The present study assessed prevalence, clinical manifestations and risk factors for recurrent wheezing events during the first 3 years of life and persistent wheezing events beyond this age in children hospitalized as young infants with acute bronchiolitis. METHODS Two groups of children aged 6 years were included. The study group comprised 150 children with a history of hospitalization for bronchiolitis, with the first event at <6 months of age. The control group comprised 66 age- and sex-matched children with no history of bronchiolitis before 6 months of age. Children in both groups had been followed until 6 years of age by their pediatricians; data were obtained retrospectively by reviewing ambulatory records during children's visits in pediatricians' clinics. The data included epidemiological parameters, prevalence, age at onset, number of and treatments given for episodes of wheezing events prior to 6 years of age, pathogens detected, and severity of acute bronchiolitis in the study group. RESULTS Overall, 58% and 27% of children in the study and control groups, respectively (P=0.001) had recurrent wheezing episodes prior to the age of 3 years. Children in the study group had earlier onset of recurrent wheezing, had more episodes of wheezing, and required more bronchodilator and systemic steroids treatments compared to the control group. CONCLUSION Hospitalization within the first six months of life for acute bronchiolitis is an independent risk factor for recurrent wheezing episodes during the first 3 years of life.

Abstract
BACKGROUND In March 2009 the pandemic influenza A (H1N1) strain was identified. The disease initially appeared to be accompanied by complications and high mortality rates. It became an endemic virus during the influenza season in our region, along with the classical seasonal H3N2. OBJECTIVES To identify the burden of pandemic influenza, its effect in pediatric patients, and complicated hospitalizations, compared to seasonal influenza years after the pandemic. METHODS A retrospective observational study was conducted at a tertiary hospital. Data were collected from the medical records of all children who were hospitalized from April 2009 to 2011 with laboratory-confirmed influenza. RESULTS Of 191 patients with influenza, 100 had the 2009 pandemic influenza, 62 had seasonal influenza, and 29 had H1N1 in 2010-2011. Patients with the 2009 H1N1 were characterized by older age, more co-morbidity conditions and more symptoms including fever, cough and rhinitis on admission. No significant differences in outcomes between the groups were recorded. Of patients hospitalized with pandemic influenza in 2009, 28% had complicated hospitalizations, compared with 17.7% of patients hospitalized with seasonal influenza in 2010-11. Children with pandemic influenza received more oseltamivir (Tamiflu®) (94% vs. 19.4%, P < 0.001) and more antibiotics than the other groups. CONCLUSIONS The type of influenza had no effect on outcome. There were no significant differences between groups in the percentages of in-hospital mortality, admission to intensive care units, prolonged hospitalization (> 9 days), or the development of complications during hospitalization.

Abstract
BACKGROUND Campylobacter bacteraemia (CB) is rare and usually occurs in immune-compromised patients. In this study we examined the incidence and epidemiology of CB in one institution over 15.5 years. METHODS The medical records of all the consecutive patients with CB admitted to our hospital from 2000 to 2015 were retrospectively reviewed. Clinical characteristics, microbiologic and outcome data were collected. RESULTS During the study period, 65 patients with CB were identified. The majority of the patients were middle aged and immune-compromised. Campylobacter jejuni was the most commonly identified species (33/47, 70%). The main underlying conditions were haematological malignancies (43%) and chronic liver disease (14%). Fifty-seven percent of the patients were receiving immunosuppressive therapy at the time of bacteraemia. The most common presenting symptoms were fever (85%), diarrhoea (40%), abdominal pain (40%), and nausea and vomiting (40%). Of the isolates tested, 97% were susceptible to macrolides, and only 35% were susceptible to quinolones. Susceptibility to quinolones decreased over the years. Most patients did not receive adequate empiric antibiotic treatment (81.5%) and about 20% never received directed therapy. Mortality and relapse rates were low (5% each). There was no association between adequate empirical or definitive antibiotic therapy and adverse outcomes. CONCLUSION The main predisposing factor for Campylobacter bacteraemia in our cohort was immunosuppression. Prognosis was generally favourable regardless of appropriateness of antibiotic therapy.

Abstract
BACKGROUND Human herpes virus-6 (HHV-6) reactivation after hematopoietic stem cell transplantation (HSCT) is well known and has been linked with several clinical manifestations. The significance of HHV-6 viremia and related complications in this setting is still unclear. OBJECTIVE To estimate the incidence of HHV-6 reactivation and associated morbidity in children undergoing allogeneic HSCT. METHODS Blood samples obtained weekly (for cytomegalovirus surveillance) from children who underwent allogeneic HCST during the period January 2006-June 2010 were retrospectively tested for the presence of HHV-6 DNA using standard real-time polymerase chain reaction (PCR) assay. Clinical records were reviewed for correlation between viremia and clinical manifestations. RESULTS Samples from 39 children were tested. Twenty patients had viral loads above 1000 copies/ml (51%) in at least one sample. Higher viral loads were seen in patients with primary immunodeficiency and in those with cord blood transplant. Attributable symptoms were present in 12 patients (60%) concurrently with positive PCR. Clinical manifestations spontaneously resolved without treatment in most cases, concomitantly with a decrease in viral load. CONCLUSIONS HHV-6 reactivation during allogeneic HSCT is common. HHV-6 reactivation should be considered in patients with graft-vs-host disease-like rash, onset of CNS symptoms, delay in engraftment, and in patients after cord blood transplantation.

Abstract
Both transplanted and leukemia patients are at high risk (HR) for invasive pulmonary aspergillosis (IPA). Methods for rapid diagnosis are crucial. Our objective was to investigate the impact of serial serum galactomannan assay (GMA) screening on IPA diagnosis in children. Between January 2010 and December 2011, all children following stem cell transplantation (SCT) or with HR leukemia were prospectively included. Serum samples for GMA were taken once-twice weekly. Results >.5 were considered positive. Patients suspected of having IPA were stratified as possible, probable, and definite. Forty-six children (median age, 8 years) were included, 38 after SCT (32 allogeneic), 8 with HR leukemia. A total of 510 samples were taken; screening period was 1-6 months for 34 patients. GMA was negative in 28 patients, all but one without suspicion of IPA. Eighteen patients had positive GMA: while four (22%) were upgraded to probable IPA, fourteen (78%) were considered as false positives (FP), some associated with piperacillin-tazobactam treatment. GMA sensitivity and specificity were 0.8 and 0.66, respectively; positive- and negative-predictive values (PPV, NPV) were 0.22 and 0.96, respectively. GMA may have a role in evaluating HR children for IPA. Both NPV and FP rates are high. The cost benefit of early detection versus over-diagnosis should be further studied.

Abstract
AIM The precise role of the influenza virus in the morbidity of hospitalised paediatric pneumonia cases is unknown. We identified how many cases hospitalised during the 2009 pandemic had influenza-associated pneumonia and assessed their severity. METHODS Children admitted to three Israeli medical centres during the 2009 influenza pandemic with radiologically confirmed pneumonia were prospectively screened for influenza. We compared the clinical, laboratory and radiologic findings for positive and negative cases. RESULTS The pandemic H1N1 virus was detected in 89 (30%) of the 297 patients hospitalised for pneumonia and 55% of the Paediatric Intensive Care Unit admissions for pneumonia. There were no significant differences in the rates of underlying disease between the two groups. Logistic regression analysis revealed that children with pandemic H1N1 virus-associated pneumonia had significantly increased disease severity than those without, with a higher incidence of hypoxemia (41.6% versus 24%) with a relative risk (RR) of 2.2, higher rate of paediatric intensive care unit admission (16.9% versus 5.8%, RR of 2.7) and higher rate of mechanical ventilation (10.1% versus 2.4%, RR:4.4). CONCLUSION During the 2009 influenza pandemic, 30% of children hospitalised for pneumonia had the influenza infection and these children displayed increased disease severity.

Abstract
OBJECTIVES To examine the long-term motor and neurocognitive outcome of children with acute encephalitis and to look at possible prognostic factors. METHODS Children who were treated for acute encephalitis in 2000-2010 were reevaluated. All children and their parents were interviewed by using structured questionnaires, and the children underwent full neurologic examinations, along with comprehensive neurocognitive, attention, and behavioral assessments. RESULTS Of the 47 children enrolled, 1 died and 29 had neurologic sequelae, including motor impairment, mental retardation, epilepsy, and attention and learning disorders. Children with encephalitis had a significantly higher prevalence of attention-deficit/hyperactivity disorder (50%) and learning disabilities (20%) compared with the reported rate (5%-10%) in the general population of Israel (P < .05) and lower IQ scores. Lower intelligence scores and significantly impaired attention and learning were found even in children who were considered fully recovered at the time of discharge. Risk factors for long-term severe neurologic sequelae were focal signs in the neurologic examination and abnormal neuroimaging on admission, confirmed infectious cause, and long hospital stay. CONCLUSIONS Encephalitis in children may be associated with significant long-term neurologic sequelae. Significant cognitive impairment, attention-deficit/hyperactivity disorder, and learning disabilities are common, and even children who were considered fully recovered at discharge may be significantly affected. Neuropsychological testing should be recommended for survivors of childhood encephalitis.

Abstract
BACKGROUND Pseudotumor cerebri or idiopathic intracranial hypertension is characterized by normal spinal fluid composition and increased intracranial pressure in the absence of a space-occupying lesion. METHODS This study describes a subgroup of 10 patients with the same typical presenting symptoms (headache, vomiting, and papilledema) but without nuchal rigidity, meningeal signs, or change in mental status. Patients had normal neuroimaging studies and intracranial hypertension but also pleocytosis in the cerebrospinal fluid, suggesting central nervous system infection. From the results it can be hypothesized that those children represent a unique subgroup of viral-induced intracranial hypertension when comparing their risk factors, clinical course, treatment, and outcome with 58 patients who had idiopathic intracranial hypertension. RESULTS All patients with viral-induced intracranial hypertension presented with papilledema but none had reduced visual acuity or abnormal visual fields, compared with 20.7% of patients who had idiopathic intracranial hypertension. They also responded better to treatment with acetazolamide, needed a shorter duration of treatment (7.7 ± 2.6 months vs 12.2 ± 6.3 months, P = 0.03), and had no recurrences. CONCLUSIONS The results suggest that children who fulfill the typical presenting signs and symptoms and all diagnostic criteria for pseudotumor cerebri other than the normal cerebrospinal fluid component may represent a unique subgroup of viral-induced intracranial hypertension and should be managed accordingly. The overall prognosis is excellent.

Abstract
AIM To describe the dynamics in the incidence of childhood invasive meningococcal disease (IMD) in Israel during a 22-year period (1989-2010). METHODS A longitudinal prospective surveillance in all 27 medical centers with pediatric services in Israel. All cases of children <15 years old with positive blood/cerebrospinal fluid (CSF) culture for Neisseria meningitidis were reported. Demographic, clinical, and bacteriological data were recorded. Meningococcal vaccine was not routinely given to Israeli children during the study period. RESULTS The mean age ± standard deviation (SD) among the 743 cases was 40.7 ± 40.2 months. The mean yearly incidence/100,000 was 2.0 ± 0.8. Age-specific incidences were 8.7 ± 2.8, 2.9 ± 1.5, and 0.8 ± 0.5 for children <1, 1-4, and >4 years old, respectively. The overall incidence decreased significantly from 3.7 in 1989 to 1.5 in 2010. Meningitis constituted 69.2 % of all cases. The most common serogroups were: B (76.9 %), C (10.9 %), Y (8.0 %), and W(135) (2.9 %). 78.6 % of all serogroup B isolates were from children <5 years old (p < 0.01). Serogroup C was found mainly in children ≥5 years old (63.4 %). The case fatality rates (CFRs) for children <1, 1-4, >4 years old, and the total study population were 9.2, 12.3, 7.7, and 9.9 %, respectively. CFRs were higher for children without meningitis (14.9 %) compared to children with meningitis (7.9 %) (p < 0.01). CONCLUSIONS Overall, and for serogroups B and W135, childhood IMD rates decreased significantly in Israel during the study period, without routine vaccine usage. The most common serogroup in all age groups was B, which was most prevalent in children <5 years old. No change in the trend of the overall CFR was noted during the study period.

Abstract
BACKGROUND Carbapenem-resistant Enterobacteriaceae, especially Klebsiella spp., have become a major health problem recently worldwide. Since 2006 the incidence of carbapenem-resistant Klebsiella pneumoniae (CRKP) infections has increased substantially in Israel. Bloodstream infections (BSIs) caused by these strains have been associated with high rates of treatment failure and mortality. AIM This study was designed to identify risk factors for carbapenem resistance among patients with healthcare-related (HCR) K. pneumoniae bacteraemia and predictors of mortality associated with HCR-CRKP bacteraemia compared with carbapenem-susceptible K. pneumoniae (CSKP). METHODS In this retrospective case-control study, all cases of K. pneumoniae bacteraemia during 2006-2008 were identified. Resistance patterns, underlying morbidities, risk factors for drug resistance and mortality rates were compared for patients with CRKP and CSKP bacteraemia. FINDINGS Two hundred and fourteen patients with CSKP bacteraemia were compared with 103 patients with CRKP bacteraemia. Severe, chronic comorbidities and prior antibiotic use were more frequent among patients with CRKP bacteraemia. On multivariate analysis prior use of macrolides and antibiotic exposure for ≥14 days remained the only independent factors associated with CRKP bacteraemia. Mortality rates of CRKP patients were significantly higher than those of CSKP patients. On multivariate analyses: bedridden status, chronic liver disease, Charlson comorbidity index ≥5, mechanical ventilation, and haemodialysis remained independently associated with mortality among patients with K. pneumoniae bacteraemia. Carbapenem resistance was not a risk factor for mortality. CONCLUSIONS Previous antibiotic exposure is a risk factor for CRKP-BSI. Mortality among patients with K. pneumoniae bacteraemia is associated with serious comorbidities, but not with carbapenem resistance.

Abstract
SETTING A tertiary university medical centre in northern Israel. OBJECTIVE To evaluate the clinical significance of non-tuberculous mycobacteria (NTM) isolated from pulmonary specimens. DESIGN Clinical and microbiological data were collected from patient files. Cases were classified as definite, probable and possible NTM. RESULTS Between 2004 and 2010, 215 cases with respiratory isolates of NTM were identified. Mycobacterium xenopi was the most common species (n = 84, 39.1%), followed by M. simiae (n = 52, 24.2%). A total of 170 (79.1%) cases were classified as possible and 24 (11.2%) as probable NTM. Only 21 (9.8%) cases were considered definite NTM, the majority of which were M. kansasii and M. avium complex. CONCLUSIONS M. xenopi and M. simiae are the most prevalent species of NTM isolated from respiratory samples in northern Israel. However, most of these isolates represent colonisation. Of the relatively small number of clinically significant isolates, M. kansasii and M. avium complex were the most common.

Abstract
BACKGROUND Staphylococcus aureus infective endocarditis (IE) is a characteristic community-acquired infection, however most cases are presently occurring in the health care setting. This study investigated the incidence and risk factors for S. aureus IE in patients with nosocomial and health care-associated S. aureus bacteraemia (SAB). METHODS Consecutive patients with health care-associated and hospital-acquired SAB were prospectively recruited over a 30-month period. Patients were followed up for at least 12 weeks after the initial positive blood culture result. The primary endpoint was the diagnosis of IE. RESULTS IE occurred in 11 of 303 patients (3.6%). Patient characteristics at diagnosis and that were associated with IE included the number of positive blood cultures obtained during hospitalization (p = 0.003), the duration of bacteraemia (p < 0.001), bacteraemia persisting for > 3 days (odds ratio (OR) 14.5, 95% confidence interval (CI) 4.0-52.8; p < 0.001), performance of echocardiography (OR 1.88, 95% CI 1.69-2.1; p = 0.001), presence of a well known predisposing risk for IE (OR 57.2, 95% CI 13.6-240.5; p < 0.001), a non-fatal McCabe score (OR 2.10, 95% CI 1.4-3.1; p = 0.02), and the duration of fever related to the infection (p = 0.026). On multivariable analysis, the presence of a predisposing risk for IE, prolonged bacteraemia, and non-fatal McCabe score remained significantly associated with IE. CONCLUSIONS In this study the incidence of IE was lower than previously reported. Three clinical characteristics were identified as risk factors for IE among patients with SAB acquired in a health care setting.

Abstract
Primary cutaneous nocardiosis is an infrequent infection among children, generally affecting immunocompromised hosts. It is caused by Gram positive bacteria, partially alcohol and acid resistant which are saprophytes of the soil, water and organic matter. In most cases the causal agent enters through inhalation, and hematogenous dissemination may occur mainly among the immune compromised patients. Direct cutaneous inoculation is less frequent, especially among children. We report an 8-year old female who lives in an urban house with a small garden, who presented with an ulcer on her right shin accompanied by surrounding cellulitis, pain, swelling and fever. The patient's medical history was unremarkable, with no exposure to animals or travelling, except for rafting on the Jordan River the previous week. Culture from the ulcer grew Nocardia brasiliensis, and she recovered after 8 weeks of therapy with trimethoprim-sulphamethoxazole.

Abstract
Legionnaires' disease is a rare cause of community acquired pneumonia in children and is exceedingly rare in infants and neonates. We describe a case of a 15 years old female, with lymphoblastic leukemia and legionella pneumophila pneumonia. Diagnosis was made by specific culture and polymerase chain reaction method from sputum and bronchoalveolar ravage specimens. Treatment was prolonged because of slow resolution and the fact that she underwent bone marrow transplantation. This emphasizes the importance of considering this rare entity in cases of severe pneumonia, especially in the immunocompromised host.

Abstract
The possible association of pseudotumor cerebri and varicella infection was previously mentioned in a few case reports. In those cases, the history and clinical features of active varicella were obvious, and signs were directly related to the varicella infection. We describe three immunocompetent children with pseudotumor cerebri as the only manifestation of Varicella zoster virus reactivation, with a review of the literature. We suggest considering Varicella zoster virus in children with pseudotumor cerebri, even in the absence of a history of recent varicella infection.

Abstract
We retrospectively evaluated neutrophil engraftment kinetics in 29 single versus nine double unit cord blood transplants (CBTs). All single CBTs were performed in pediatric patients (non-malignant/malignant diseases, 19/10), while all double CBTs were performed in adults (n = 8) and an adolescent (n = 1) with hematological malignancies. Median follow-up time was 2.3 years (range, 0.1-13.5 years). Engraftment was achieved in 69% and 89% of the single and double cord blood (CB) groups, respectively. Similarly, median day of engraftment was not different for the single versus the double CBTs, at 19 and 23 days, respectively, and the neutrophil engraftment kinetics was similar in the two groups. Our data indicate that adults without sufficient nucleated cell doses in a single CB unit may receive two units with similar engraftment kinetics to those of children receiving only a single unit.

Abstract
BACKGROUND AND OBJECTIVES Hemodialysis (HD) catheter-related complications are regarded as the main cause of HD failure in infants and children with ESRD. In this study, we determined HD catheter infection rates and survival times in children. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We analyzed demographic, clinical, laboratory, and microbiologic data on all infants and children with ESRD who received HD therapy through a tunneled central venous catheter (CVC) in our Pediatric Dialysis Unit between January 2001 and December 2009. Our strict care of HD-CVCs makes no use of any kind of prophylactic antibiotic therapy. RESULTS Twenty-nine children with ESRD (median age, 10 years) received HD through a CVC, for a total of 22,892 days during the study period. Eleven (38%) children were infants (<1 year of age) who received HD for a cumulative 3779 days (16% of total). Fifty-nine CVCs were inserted, of which 13 (22%) were in infants. There were 12 episodes of CVC infection-a rate of 0.52/1000 CVC days. Four (33%) episodes occurred in infants-a rate of 1.06/1000 CVC days. Only three (5%) of the CVCs were removed because of infection. Median catheter survival time for all children was 310 days and for infants was 211 days. CONCLUSIONS Very low CVC infection rates (one infection per 5 CVC years) and prolonged CVC survival times (around 1 year) are achievable in infants and children with ESRD receiving HD therapy by adhering to a strict catheter management protocol and without using prophylactic antibiotic therapy.

Abstract
OBJECTIVES To describe the clinical characteristics of children hospitalized with 2009 influenza A(H1N1) infection in Israel and the risk factors associated with this infection. DESIGN Prospective collection of data on children hospitalized with 2009 influenza A(H1N1) infection. SETTING Seven medical centers around Israel. Patients From July 12, 2009, to December 24, 2009, all patients 18 years or younger hospitalized with acute respiratory or acute unspecified febrile illness were screened for 2009 influenza A(H1N1) virus by reverse transcription-polymerase chain reaction. INTERVENTION Prospective data collection for patients with confirmed infection. MAIN OUTCOME MEASURES Clinical characteristics of patients and hospitalization rates. RESULTS The mean age of 478 patients studied was 6.1 years. Forty-two patients (8.8%) were admitted to the pediatric intensive care unit; 3 patients (0.6%) died. The most frequent clinical presentations were pneumonia, influenza-like illness, wheezing exacerbation, and convulsions. Predisposing underlying illnesses were detected in 48.7% of patients. Patients with metabolic and neurologic disorders were at highest risk for severe complications (relative risk, 6.5 and 2.9, respectively). In addition, patients with cyanotic heart lesions and infants 3 months or younger who were born at 33 weeks' gestation or earlier tended to require higher rates of mechanical ventilation. The hospitalization rate for 2009 influenza A(H1N1) was 0.7 per 1000 children. The mortality rate was 3.6 per 1 000 000 children. CONCLUSIONS The severity variables for 2009 influenza A(H1N1) were similar to the figures reported for seasonal influenza. Patients with underlying metabolic and neurologic metabolic disorders and presumably patients with cyanotic heart lesions and infants born prematurely are at highest risk for severe complications following 2009 influenza A(H1N1) infection.
