Ampicillin-Sulbactam-Induced Liver Injury in a Pediatric Patient.

Drug-induced liver injury (DILI) is a rare adverse drug reaction (ADR) in pediatric patients and limited reports exist examining ampicillin-sulbactam-induced liver injury. This report summarizes a 12-year-old male who received ampicillin-sulbactam and subsequently developed liver injury characterized by elevated serum aminotransferases and bilirubin. Ampicillin-sulbactam was subsequently discontinued and the patient's liver function tests (LFTs) rapidly improved. This report describes the rare adverse reaction of ampicillin-sulbactam-induced liver injury.

Use of cidofovir with extracorporeal membrane oxygenation to treat adenovirus-associated acute respiratory distress syndrome in paediatric patients- a case series.

WHAT IS KNOWN AND OBJECTIVE: Reports of cidofovir dosing with extracorporeal membrane oxygenation (ECMO) support are limited. This case series describes our clinical experience and provides a literature review regarding cidofovir dosing in paediatric patients requiring ECMO support. CASE SUMMARY: Three patients with adenovirus-associated acute respiratory distress syndrome (ARDS) were treated with cidofovir while requiring ECMO support. A 27-month-old patient was treated with cidofovir 1 mg/kg/dose three times weekly, and a 19-month-old patient and an 18-year-old patient were treated with cidofovir 5 mg/kg/dose weekly. WHAT IS NEW AND CONCLUSION: This case series describes the dosing and positive clinical response of cidofovir in paediatric patients with adenovirus-associated ARDS requiring ECMO support.

The Pharmacokinetics of Moxifloxacin in Cerebrospinal Fluid Following Intravenous Administration: A Report of Successfully Treated Infant with Mycoplasma hominis Meningitis.

A female infant underwent myelomeningocele repair and developed persistent ventricular dilatation. Cerebrospinal fluid (CSF) indices demonstrated meningitis with cultures growing Mycoplasma hominis. The infant was treated with multiple antibiotics including moxifloxacin. Moxifloxacin CSF levels were obtained for pharmacokinetic analysis. This case report adds the importance of understanding the pharmacokinetics of CSF moxifloxacin levels among infants.

Resource utilization of cytomegalovirus immune globulin in prevention and treatment of cytomegalovirus infection in pediatric heart transplantation.

BACKGROUND: There is debate whether cytomegalovirus immunoglobulin (CMV-Ig) is also needed for CMV prevention in heart transplant recipients in the era of good anti-viral drugs. METHODS: We conducted a cost-savings quality initiative on CMV-Ig eventually leading to discontinuation of routine use of CMV-Ig for CMV prevention. Subsequently, a retrospective cohort study was conducted, comparing patients in cohort I (CMV-Ig plus anti-viral drugs, 2013-2015) to cohort II (anti-virals alone, 2015-2017). The medication acquisition costs and outcomes of CMV infection were assessed. RESULTS: There were 39 total patients: 22/39(56%) in cohort I, with mean follow-up of 35.14 ± 17.38 months and 17/39(44%) in cohort II, mean follow-up of 19.12 ± 7.08 months. In cohort I, 5/22(22.7%) patients died from causes unrelated to CMV and 0/17 in cohort II died. There were 5/22(22.7%) patients in cohort I, and 2/17(9%) patients in cohort II that developed CMV infection (P = .508). Freedom from rejection was 81.8% (18/22) in cohort I, and 71% (12/17) in cohort II (P = .46), and 100% for allograft vasculopathy. There was significant reduction in medication acquisition cost following the protocol change of $260 839 or $15 343 per patient. CONCLUSION: Our study demonstrated an acquisition cost savings with similar clinical outcomes utilizing anti-viral CMV prophylaxis alone vs anti-viral prophylaxis plus CMV-Ig.

Clinical Experience with Daptomycin in Pediatrics.

INTRODUCTION: The management of gram-positive infections has been complicated in recent years by the emergence of antimicrobial resistance, leaving fewer options for therapy. Daptomycin is a lipopeptide antibiotic used for the systemic treatment of gram-positive infections. It has a distinct mechanism of action and a favorable side effect profile, and it requires once/day dosing. Unfortunately, there is a paucity of safety, efficacy, and pharmacokinetic data in neonatal and pediatric patients. The objective of this study was to review our experience with daptomycin use for the treatment of gram-positive infections in these patient populations. METHODS: We conducted a retrospective analysis of electronic medical records of hospitalized children who received daptomycin between October 2008 and June 2014 for the treatment of proven gram-positive infections. RESULTS: Of the 146 patients who received at least 3 days of daptomycin therapy, 109 patients had a proven gram-positive infection and were included for further analysis. Of the 109 patients, 71 were males (65%) and the median age was 12 years (range: 2.5 mo to 24 yrs). The median duration of therapy was 12 days (range: 3-121 days; mean = 16 days). Catheter-related bloodstream infections were the most common type of infections (n=81 patients) in those receiving daptomycin treatment. One hundred seven patients (98%) had documented improvement and resolution at the time of hospital discharge. One hundred four patients (95%) had a baseline creatine phosphokinase (CPK) level obtained. Of these 104 patients, 48 (46%) had at least one follow-up CPK level after the start of therapy. Three patients' charts showed laboratory evidence of elevated CPK values. CONCLUSIONS: The majority of patients demonstrated clinical improvement after receiving daptomycin as primary therapy for proven gram-positive infections. Larger randomized controlled trials focusing on safety and efficacy are necessary to assess these outcomes with daptomycin use in the pediatric population.

Antimicrobial stewardship in pediatrics: how every pediatrician can be a steward.

Antimicrobial stewardship (AS) programs are effective in improving clinical outcomes associated with antimicrobial therapies while improving patient safety by reducing adverse events and development of bacterial resistance. Understanding the basic principles of AS is essential to the successful development and implementation of AS strategies. Identifying and developing strategies to address barriers and challenges to AS can facilitate the establishment of financial, administrative, and organizational support, and agreement and participation by individual prescribers. Review of published outcomes of AS demonstrates the effectiveness in reducing unnecessary antimicrobial use and adverse events such as Clostridium difficile infections. We also illustrate the need for further research and expansion of AS activities to office-based practices and communities by using novel and innovative AS strategies and by influencing regional and national policies.

Trimethoprim-sulfamethoxazole therapy for children with acute osteomyelitis.

BACKGROUND: The emergence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has complicated the conventional management of osteomyelitis. While oral clindamycin is commonly used to treat acute CA-MRSA osteomyelitis, the emergence of inducible clindamycin resistance among CA-MRSA isolates has made alternative therapy necessary. The excellent oral bioavailability, susceptibility profile, favorable palatability, and low cost of trimethoprim-sulfamethoxazole (TMP-SMX) make this drug an attractive option for treating osteomyelitis, yet its clinical efficacy for osteomyelitis has not been established. METHODS: Between October 1998 and September 2009, 20 children who received a TMP-SMX-containing regimen for acute osteomyelitis at All Children's Hospital were identified from hospital records, and their cases reviewed for clinical outcome and drug safety. RESULTS: Patients ranged in age from 9 months to 17 years. Twelve (60%) of the patients were male. Causative pathogens were found in 8 (40%) cases of which 5 were CA-MRSA and 3 were methicillin-susceptible Staphylococcus aureus. Eleven patients (55%) received TMP-SMX as their primary therapy. The median dose of TMP-SMX was 16.4 mg/kg/d. During TMP-SMX therapy, 8 patients (40%) experienced adverse events; all were considered mild. Duration of total therapy was 26 to 59 days, with a median of 40 days. All 20 patients were considered cured of their infection at the end of therapy. CONCLUSION: Orally administered TMP-SMX appears to be a useful and well-tolerated therapy for treatment of acute osteomyelitis in children. Further prospective comparative studies will be needed to confirm this observation.

Sustaining and spreading the reduction of adverse drug events in a multicenter collaborative.

OBJECTIVES: Adverse drug events (ADEs) occur more frequently in pediatric patients than adults. ADEs frequently cause serious harm to children and increase the cost of care. The purpose of this study was to decrease ADEs by targeting the entire medication-delivery system for all high-risk medications. METHODS: Thirteen freestanding children's hospitals participated in this ADE collaborative. An advisory panel developed a change package of interventions that consisted of standardization of medication-ordering (eg, consensus-based protocols and order sets and high-alert medication protocols), reliable medication-dispensing processes (eg, automated dispensing cabinets and redesign of floor stock procedures), reliable medication-administration processes (eg, safe pump use and reducing interruptions), improvement of patient safety culture (eg, safety-culture changes and reduction of staff intimidation), and clinical decision support (eg, increase ADE detection and redesign care systems). ADE rates were compared from the 3-month baseline period to quarters of the 12-month intervention phase. ADE rates were categorized further as opioid related and other medication related. RESULTS: From baseline to the final quarter, the collaborative resulted in a 42% decrease in total ADEs, a 51% decrease in opioid-related ADEs, and a 41% decrease in other medication ADEs. CONCLUSION: A pediatric collaborative that targeted the medication-delivery system decreased the rate of ADEs at participating institutions.
