Background Incorrect dosing is the most frequent prescribing error in neonatology, with antibiotics being the most frequently prescribed medicines. Computer physician order entry and clinical decision support systems can create consistency contributing to a reduction of medication errors. Although evidence-based dosing recommendations should be included in such systems, the evidence is not always available and subsequently, dosing recommendations mentioned in guidelines and textbooks are often based on expert opinion. Objective To compare dosage recommendations for antibiotics in neonates with sepsis provided by eight commonly used and well-established international reference sources. Setting An expert team from our Dutch tertiary care neonatal intensive care unit selected eight well-established international reference sources. Method Daily doses of the seven most frequently used antibiotics in the treatment of neonatal sepsis, classified by categories for birth weight and gestational age, were identified from eight well-respected reference sources in neonatology/pediatric infectious diseases. Main outcome measure Standardized average daily dosage. Results A substantial variation in dosage recommendations of antibiotics for neonatal sepsis between the reference sources was shown. Dosage recommendations of ampicillin, ceftazidime, meropenem and vancomycin varied more than recommendations for benzylpenicillin, cefotaxime and gentamicin. One reference source showed a larger variation in dosage recommendations in comparison to the average recommended daily dosage, compared to the other reference sources. Conclusion Antibiotic dosage recommendations for neonates with sepsis can be derived from important reference sources and guidelines. Further exploration to overcome variation in dosage recommendations is necessary to obtain standardized dosage regimens. [ABSTRACT FROM AUTHOR]

This study was aimed at finding predictors of invasive fungal infection (IFI) after pediatric allogeneic hematopoietic SCT (HSCT). All children who received allogeneic HSCT in the Wilhelmina Children's Hospital Utrecht between 2004 and 2012 were included. HSCT data were prospectively collected. Patients were retrospectively classified into high- or low-risk groups for developing IFI using criteria based on available literature. Predictors for the occurrence of IFI were analyzed using Cox regression models. We used logistic regression models to analyze the association between other HSCT-related complications and IFI. Secondary outcomes were overall survival and treatment-related mortality (TRM). Two-hundred nine patients were included in the analysis; median age was 6.6 years. The cumulative incidence of IFI was 12%. In patients classified as 'low risk' (n=75), only 5.3% developed IFI (odds ratio (OR): 0.325; P=0.047). In multivariate analysis, a predictor for the occurrence of IFI was an a priori determined HSCT TRM risk >20% (based on EBMT-risk score). Post-HSCT, the administration of high-dose steroids was associated with IFI (OR: 4.458; P=0.010). Patients who developed IFI showed an increased risk of TRM (OR: 3.773; P=0.004). These results confirm that risk group stratification should guide intensity of monitoring for IFI and use of antifungal prophylaxis. [ABSTRACT FROM AUTHOR]

Intensified chemotherapy regimens resulting in improved survival of children with acute lymphocytic leukemia (ALL) lead to concerns about therapy-induced immune damage reflected by the loss of protection of previous immunizations and the efficacy of (re-)vaccination. The severity of secondary immunodeficiency, however, is not clear and knowledge is based on a limited number of studies. We performed a systematic review on literature concerning vaccination data of children with ALL published since 1980. Eight studies fulfilled the inclusion criteria. Regarding antibody titers after treatment, the number of children who had preserved the defined protection level for antibodies differed widely, ranging from 17 to 98% for diphtheria, 27 to 82% for Bordetella pertussis, 20 to 98% for tetanus, 62 to 100% for poliomyelitis, 35 to 100% for Haemophilus influenzae type B (HiB), 29 to 92% for mumps, 29 to 60% for measles and 72 to 92% for rubella. Most patients however responded to revaccination, demonstrating immunological recovery. Although the designs and results of the included studies varied widely, it can be concluded that cytostatic therapy for ALL in children results in a temporarily reduction of specific antibody levels. Memory is preserved but revaccination may be warranted. This is the first systematic review and the best possible current approximation of chemotherapy-induced immune damage in children after ALL treatment.Leukemia (2006) 20, 1717–1722. doi:10.1038/sj.leu.2404326; published online 3 August 2006 [ABSTRACT FROM AUTHOR]
