Secretory phospholipase A 2: a marker of infection in febrile children presenting to a pediatric ED

Background Fever is a common presenting complaint to the emergency department (ED), and the evaluation of the febrile child remains a challenging task. Objective The aim of this study was to examine the relationship between secretory phospholipase A 2 (sPLA2) and infection in febrile children. Methods A prospective convenience sample of children presenting with fever to an urban pediatric ED were studied. Blood and urine cultures, a complete blood count, and serum concentrations of sPLA2 were obtained, and patients were compared based on their final diagnosis of either a viral or bacterial infection. Results In the 76 patients enrolled, 60 were diagnosed with a viral infection, 14 with a bacterial infection, 1 with Kawasaki disease, and 1 with acute lymphoblastic leukemia. The difference in the serum concentration of sPLA2 in patients with viral infections (22 ± 34 ng/mL) versus those with bacterial infections (190 ± 179 ng/mL) was statistically significant ( P < .0001). Receiver operator characteristic curve analysis revealed that sPLA2 was more accurate at predicting bacterial infection (area under the curve = 0.89) than the total white blood cell count (area under the curve = 0.71) and that a value of more than 20 ng/mL had a sensitivity of 93%, specificity of 67%, positive predictive value of 39%, and negative predictive value of 97%. Conclusion Secretory phospholipase A 2 differs significantly in children with viral versus bacterial infection and seems to be a reliable screening test for bacterial infection in febrile children.

Human Metapneumovirus Infection in Febrile Children with Lower Respiratory Diseases in Primary Care Settings in Hiroshima, Japan

Human metapneumovirus (hMPV) has been shown to be a leading cause of viral lower respiratory tract infections in children. Nevertheless, few reports regarding hMPV infections over consecutive years in children in primary care settings are available. We carried out virologic and clinical studies to determine the role of hMPV in febrile lower respiratory infections in children at a primary care clinic over 3 years and 5 months. Nasopharyngeal aspirates obtained from children with acute respiratory tract infections accompanied by high-grade fever (> or = 39 degrees C) and productive cough were studied for hMPV by reverse transcription-polymerase chain reaction and for other respiratory viruses by viral cultures and immunoassays. Of 379 patients tested, 202 were positive for at least 1 virus, including 98 with hMPV, 69 with respiratory syncytial virus, 18 with adenovirus, 12 with enterovirus, 8 with parainfluenza virus, 3 with rhinovirus, 2 with influenza virus type C, and 1 with herpes simplex virus. The male:female ratio of hMPV-infected children was 0.96:1 with an overall mean age of 3.5 years (range, 2 months to 9 years). These infections occurred predominantly from February to July, and the hospitalization rate was 4%. Of 93 patients infected with hMPV alone, 52 (56%) showed evidence of a lower respiratory tract infection.

The incidence of urinary tract infections in febrile children during a two-year period in Tehran, Iran

Of 433 febrile children examined in the paediatric clinics of two university hospitals in Tehran, Iran, 39 (9%) children (27 girls and 12 boys) were diagnosed as having urinary tract infection in which Escherichia coli was the most frequently detected pathogen (84.6%). According to the voiding cystourethrogram, nine (75%) boys and 17 (63%) girls had urinary tract abnormalities. This result is slightly higher than seen in other reports from developing countries.

Polytomous regression did not outperform dichotomous logistic regression in diagnosing serious bacterial infections in febrile children

Objective To compare polytomous and dichotomous logistic regression analyses in diagnosing serious bacterial infections (SBIs) in children with fever without apparent source (FWS). Study Design and Setting We analyzed data of 595 children aged 1–36 months, who attended the emergency department with fever without source. Outcome categories were SBI, subdivided in pneumonia and other-SBI (OSBI), and non-SBI. Potential predictors were selected based on previous studies and literature. Four models were developed: a polytomous model, estimating probabilities for three diagnostic categories simultaneously; two sequential dichotomous models, which differed in variable selection, discriminating SBI and non-SBI in step 1, and pneumonia and OSBI in step 2; and model 4, where each outcome category was opposed to the other two. The models were compared with respect to the area under the receiver-operating characteristic curve (AUC) for each of the three outcome categories and to the variable selection. Results Small differences were found in the variables that were selected in the polytomous and dichotomous models. The AUCs of the three outcome categories were similar for each modeling strategy. Conclusion A polytomous logistic regression analysis did not outperform sequential and single application of dichotomous logistic regression analyses in diagnosing SBIs in children with FWS.

Evaluation of the Nitrite Test in Screening for Urinary Tract Infection in Febrile Children with Sickle Cell Anaemia

Background: Urinary tract infection (UTI) is a significant cause of morbidity in children and individuals with sickle cell anaemia (SCA) have been reported to be at increased risk. It will be useful to have a simple means of screening such children for UTI with a view to instituting prompt treatment. Objectives: The objective of the study was to evaluate the usefulness of the nitrite test in detecting UTI in febrile SCA children. Methods: This prospective study was carried out in the department of Paediatrics, University College Hospital, Ibadan. The study group consisted of 171 children aged one to 15 years with SCA presenting with fever (temperature e” 37.5oC). Midstream urine specimen was collected from each patient and subjected to nitrite test, microscopy, culture and sensitivity. Results: There was significant bacteriuria in 37 (21.6 percent) children. A positive test for nitrite was obtained in the urine of eight patients, seven of whom had bacteriuria. The nitrite test in detecting bacteriuria had a specificity of 99.2 percent, a sensitivity of 18.9 percent, a positive predictive value of 87.5 percent and a negative predictive value of 81.6 percent. A positive nitrite test was significantly associated with bacteriuria, while a negative test was also significantly associated with an absence of bacteriuria. Conclusion: The nitrite test is useful as a screening test for UTI in SCA children. However, in sick children, urine microscopy and culture should still be done in spite of a negative test.

Fever in the new millennium: a review of recent studies of markers of serious bacterial infection in febrile children

Evaluation of a febrile infant or child for serious bacterial infections (SBI) can be a challenging task; there is no single reliable predictor of SBI in infants. This review examines some of the recent work evaluating the usefulness of indicators for SBI, such as white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6). While WBC is traditionally used as an indicator of serious infection, it appears to be the least specific and sensitive test in children. CRP and PCT are the most promising, but neither is an ideal single indicator by itself, especially in infants. There has been very limited experience with PCT in this country, however. IL-6 is more useful than WBC but less accurate than either CRP or PCT. Much progress has been made in recent years in finding more accurate indicators of SBI than WBC. However, while recent developments have given clinicians some new tools in evaluating febrile infants and children, it remains a formidable undertaking. In the especially vulnerable infant population, the holy grail of a single ideal SBI indicator remains elusive.

Infektionen in der pädiatrischen Hämatologie und Onkologie

Infectious complications are still a major cause of morbidity and mortality in pediatric patients undergoing therapy for malignancy. Therapy-induced neutropenia is the most important risk factor for infectious risk in pediatric patients with cancer, but other factors, such as alterations in skin/mucosal barriers, and defects in cell-mediated or humoral immunity also contribute to the risk for infection. In most centers, about two thirds of bacteremic isolates are gram-positive pathogens, whereas gram-negative organisms are isolated less frequently, but are associated with considerably higher mortality rates. Prolonged neutropenia increases the risk for invasive fungal infection. In most cases, fever is an important and early indication of serious infection, particularly in children with neutropenia. Discrimination between serious and inconsequential infection in febrile children with neutropenia at the time of presentation is difficult, and serum markers have not been proven to reliably indicate infection. Although several groups investigate risk categories based on clinical tests or the genetic background, the current paradigm is to treat all pediatric patients with neutropenia and fever with intravenous broad-spectrum antibiotics. It is hoped that the identification of one or more predictive factors may be useful for tailoring antibiotic prophylaxis and therapy in children with cancer.

Urinary tract infection in febrile children with sickle cell anaemia in Ibadan, Nigeria.

A prospective study to determine the prevalence of bacteriuria and bacterial isolates in the urine of febrile children with sickle cell anaemia (SCA) was carried out at University College Hospital, Ibadan. Altogether, 171 febrile children (aged 1-15 years) with SCA and 171 age- and sex-matched controls were studied. After obtaining a history of the illness from the parents or guardians, each child was physically examined and a mid-stream urine specimen collected and subjected to microscopy and culture. The prevalence of bacteriuria in children with SCA was 21.6% compared with 15.8% in the controls. Escherichia coli and Klebsiella species were the predominant isolates from the urine, accounting for 64.9% and 18.9%, respectively, of the isolates from the SCA group and 63% and 22.2%, respectively, in the controls. In the SCA group, significant bacteriuria also occurred with other conditions such as pneumonia and osteomyelitis. Urinary tract infection (UTI) is common in children with SCA. Routine screening for it is therefore recommended during febrile illnesses. Children with fever from other overt causes, however, should not be exempted from the urine screening procedure in case there might be concomitant UTI.

ULA TESTING FOR SERIOUS INFECTION IN CHILDREN.

Latex agglutination tests on body fluids have been used for years to rapidly detect serious bacterial infections in febrile children. This retrospective study evaluated how well urine latex agglutination (ULA) testing identifies infected children. Of 1629 children tested with ULA for invasive infection by Haemophilus influenzae, Streptococcus …

Prevalence of bacteriuria in febrile children.

To determine the risk of urinary tract infections in acutely ill febrile children younger than 5 years of age we obtained a urine culture from 664 children presenting to our walk-in clinic with an acute febrile episode. Only 11 children (1.7%) had significant bacteriuria. This figure is similar to the number of children who would be expected to have asymptomatic bacteriuria. These results suggest that pediatricians are not missing the diagnosis of urinary tract infection in febrile children.
