An Infant Formula with Partially Hydrolyzed Whey Protein Supports Adequate Growth and Is Safe and Well-Tolerated in Healthy, Term Infants: A Randomized, Double-Blind, Equivalence Trial

The current study evaluates the safety and tolerance of a partially hydrolyzed whey protein-based infant formula (PHF) versus an in intact cow's milk protein formula (IPF). Breastfed infants were included as a reference group. In a multi-country, multicenter, randomized, double-blinded, controlled clinical trial, infants whose mothers intended to fully formula feed were randomized to PHF (n= 134) or IPF (n= 134) from <= 14 days to 17 weeks of age. The equivalence analysis of weight gain per day within margins of +/-3 g/d (primary outcome), the recorded adverse events, growth and gastro-intestinal tolerance parameters were considered for the safety evaluation. Equivalence of weight gain per day from enrolment until 17 weeks of age was demonstrated in the PHF group compared to the IPF group (difference in means -1.2 g/d; 90% CI (-2.42; 0.02)), with estimated means (SE) of 30.2 (0.5) g/d and 31.4 (0.5) g/d, respectively. No significant differences in growth outcomes, the number, severity or type of (serious) adverse events and tolerance outcomes, were observed between the two formula groups. A partially hydrolyzed whey protein-based infant formula supports adequate infant growth, with a daily weight gain equivalent to a standard intact protein-based formula; it is also safe for use and well-tolerated in healthy term infants

A Randomized, Prospective Study of Pediatric Patients With Community-acquired Pneumonia Treated With Ceftaroline Versus Ceftriaxone

Background: Community-acquired bacterial pneumonia (CABP) remains a major infection among children, despite the use of pneumococcal vaccination. Ceftaroline fosamil is a broad-spectrum cephalosporin antibiotic with activity against many bacteria, including Streptococcus pneumoniae (both penicillin-nonsusceptible and multidrug-resistant strains) and Staphylococcus aureus (including methicillin-resistant S. aureus). This article describes the safety, tolerability, and effectiveness of ceftaroline fosamil in the treatment of pediatric patients hospitalized with CABP, from a randomized, active-controlled, observer-blinded clinical study (registration number NCT01530763). Methods: Pediatric patients were stratified into 4 age cohorts and randomized (3:1) to receive either intravenous ceftaroline fosamil or ceftriaxone, with optional oral switch for a total treatment duration of 5-14 days. Enrollment was planned for 160 patients. Data collected included demographics, infection characteristics and pathogens. Treatment-emergent adverse events, clinical outcomes, and microbiologic responses were assessed. Results: Ceftaroline fosamil was well tolerated. Similar percentages of patients in the ceftaroline fosamil (55/121; 45%) and ceftriaxone (18/39; 46%) groups reported treatment-emergent adverse events. Coombs seroconversion was observed in 17% of patients in the ceftaroline fosamil group; however, no evidence of hemolytic anemia or hemolysis was found. No deaths were reported during the study. Ceftaroline fosamil had similar effectiveness to ceftriaxone, with high clinical cure rates at test-of-cure in the modified intent-to-treat population (94/107; 88% and 32/36; 89%, respectively). Three documented S. aureus infections were successfully treated in the ceftaroline group, including one caused by methicillin-resistant S. aureus. Conclusions: The results of this study suggest that ceftaroline fosamil may be an important treatment option for pediatric patients hospitalized with CABP

Blood samples were collected pre-dose on days 5 and 6. On days 7 and 8, blood and urine samples were collected and safety was evaluated. 5-ASA and Ac-5-ASA plasma and urine concentrations were analyzed by non-compartmental methods and used to develop a population pharmacokinetic model.Results: Fifty-two subjects (21 [30&nbsp;mg/kg]; 22 [60&nbsp;mg/kg]; 9 [100&nbsp;mg/kg]) were randomized. On day 7, systemic exposures of 5-ASA and Ac-5-ASA exhibited a dose-proportional increase between 30 and 60&nbsp;mg/kg/day cohorts. For 30, 60, and 100&nbsp;mg/kg/day doses, mean percentages of 5-ASA absorbed were 29.4%, 27.0%, and 22.1%, respectively. Simulated steady-state exposures and variabilities for 5-ASA and Ac-5-ASA (coefficient of variation approximately 50% and 40%&ndash;45%, respectively) were similar to those observed previously in adults at comparable doses. Treatment-emergent adverse events were reported by ten subjects. Events were similar among different doses and age groups with no new safety signals identified.Conclusion: Children and adolescents with UC receiving multimatrix mesalamine demonstrated 5-ASA and Ac-5-ASA pharmacokinetic profiles similar to historical adult data. Multimatrix mesalamine was well tolerated across all dose and age groups. ClinicalTrials.gov Identifier: NCT01130844. Keywords: ulcerative colitis, mesalamine, pharmacolog

Prediction of moderate and high grade vesicoureteral reflux after a first febrile urinary tract infection in children: Construction and internal validation of a clinical decision rule

Purpose: Urinary tract infection leads to a diagnosis of moderate or high grade (III or higher) vesicoureteral reflux in approximately 15% of children. Predicting reflux grade III or higher would make it possible to restrict cystography to high risk cases. We aimed to derive a clinical decision rule to predict vesicoureteral reflux grade III or higher in children with a first febrile urinary tract infection. Materials and Methods: We conducted a secondary analysis of prospective series including all children with a first febrile urinary tract infection from the 8 European participating university hospitals. Results: A total of 494 patients (197 boys, reflux grade III or higher in 11%) were included. Procalcitonin and ureteral dilatation on ultrasound were significantly associated with reflux grade III or higher and then combined into a prediction model with an ROC AUC of 0.75 (95% CI 0.690.81). Given the prespecified constraint of achieving at least 85% sensitivity, our model led to the clinical decision rule, for children with a first febrile urinary tract infection cystography should be performed in cases with ureteral dilatation and serum procalcitonin level 0.17 ng/ml or higher, or without ureteral dilatation (ie ureter not visible) when serum procalcitonin level is 0.63 ng/ml or higher. The rule had 86% sensitivity (95% CI 7493) with 47% specificity (95% CI 4251). Internal cross-validation produced 86% sensitivity (95% CI 7993) and 43% specificity (95% CI 3947). Conclusions: A clinical decision rule was derived to enable a selective approach to cystography in children with urinary tract infection. The rule predicts high grade vesicoureteral reflux with approximately 85% sensitivity and avoids half of the cystograms that do not find reflux grade III or higher. Further validation is needed before its widespread use. © 2012 American Urological Association Education and Research, Inc
