RESUMEN

BACKGROUND: Infection prevention and timely and effective treatment are among the major aims of care in kidney transplant recipients. Pre-transplant vaccination and pre-transplant viral screening have been extensively studied and are now considered standard practice. Early post-operative infection surveillance is mandatory in other vulnerable cohorts, but has not been extensively studied in this population. We hypothesized that surveillance of the most common bacterial infection types in the post-transplant setting would be beneficial and identify key areas for improvement. METHODS: All adult kidney transplant recipients whose surgeries were performed in the Irish national kidney transplant unit over a 1-year period had prospective early post-transplant (first 30 days) infection surveillance in 2014 for surgical site infection, urinary tract infection, and secondary bloodstream infections (Group T0). Several key changes were implemented following scrutiny of infection patterns and clinical practice. Subsequently, infection surveillance was undertaken for 2016 and 2017 (Group T1) to assess the impact of these changes. RESULTS: Between 2014 and 2017, the number of kidney transplants increased by 32%. The following aspects of clinical practice were the focus of change following analysis of Group T0 data: timing of surgical antimicrobial prophylaxis (SAP) administration, choice of SAP antimicrobial agent, and routine microbiological testing in the peri-operative period. Following implementation of these changes, the timing of SAP administration was greatly improved (45%-100% of cases appropriately timed). The infection rate decreased from 8.9% to 7.4% in 2016, with a further decrease to 4% in 2017 (OR 0.42 (95% CI: 0.16-1.10); P = .08). Compliance with pre-operative microbiological screening improved in Group T1. CONCLUSIONS: Simple clinical practice changes, implemented upon analysis of common bacterial infection surveillance data in the first 30 days after kidney transplantation resulted in more effective SAP administration and improved compliance with routine microbiological testing in the peri-operative period. These interventions have potentially contributed to reduced early post-operative infection rates, despite increased transplant activity in the unit. Infection surveillance is an important and under-utilized way of reducing infections in this vulnerable patient cohort.

RESUMEN

RATIONALE: Speed of heart rate recovery (HRR) may serve as an important biomarker of aging and mortality. OBJECTIVE: To examine whether the speed of HRR after an orthostatic maneuver (ie, active stand from supine position) predicts mortality. METHODS AND RESULTS: A longitudinal cohort study involving a nationally representative sample of community-dwelling older individuals aged ≥50 years. A total of 4475 participants completed an active stand at baseline as part of a detailed clinic-based cardiovascular assessment. Beat-to-beat heart rate and blood pressure responses to standing were measured during a 2-minute window using a finometer and binned in 10-s intervals. We modeled HRR to the stand by age group, cardiovascular disease burden, and mortality status using a random effects model. Mortality status during a mean follow-up duration of 4.3 years served as the primary end point (n=138). Speed of HRR in the immediate 20 s after standing was a strong predictor of mortality. A 1-bpm slower HRR between 10 and 20 s after standing increased the hazard of mortality by 6% controlling for established risk factors. A clear dose-response relationship was evident. Sixty-nine participants in the slowest HRR quartile died during the observation period compared with 14 participants in the fastest HRR quartile. Participants in the slowest recovery quartile were 2.3× more likely to die compared with those in the fastest recovery quartile. CONCLUSIONS: Speed of orthostatic HRR predicts mortality and may aid clinical decision making. Attenuated orthostatic HRR may reflect dysregulation of the parasympathetic branch of the autonomic nervous system.

RESUMEN

Overexpression of human epidermal growth factor receptor (HER/EGFR) is associated with various tumors, including ependymomas. To investigate whether EGFR inhibition was of benefit in pediatric patients with recurrent ependymoma, a multi-center, randomized, open-label, phase 2 study of oral erlotinib versus oral etoposide was undertaken. Twenty-five patients were randomized to receive erlotinib 85 mg/m(2) daily or etoposide 50 mg/m(2)/day for 21 consecutive days followed by a 7-day rest period. Courses were repeated every 28 days. In the erlotinib arm, no patient achieved a complete, partial, or minor response, and only 2 (15.4 %) patients showed stable disease as their best response. In the etoposide arm, 2 patients (16.7 %) demonstrated partial responses, 1 (8.3 %) patient demonstrated a minor response, and 2 (16.7 %) showed prolonged stable disease, for a prolonged disease control rate of 41.7 %. Three patients received at least nine cycles of etoposide (range 9-24 cycles) before discontinuing at the request of the physician and/or family. Four patients who failed etoposide in this study received erlotinib in a companion single arm study; none had a response. The futility criteria were met at the second interim analysis, and both studies were discontinued. Pharmacokinetics of erlotinib were similar to previous observations in pediatric patients. Overall, erlotinib was well tolerated and safety was consistent with its established profile in adults. The overall risk-benefit profile does not support the use of erlotinib in pediatric patients with recurrent ependymoma, whereas single-agent etoposide appears to have efficacy in a subset of patients.

RESUMEN

BACKGROUND: The open-label, single-arm enzalutamide expanded access program (EAP) in the United States and Canada evaluated the safety of enzalutamide in patients with metastatic castration-resistant prostate cancer (mCRPC) who had previously received docetaxel. METHODS: Patients (n = 507) received enzalutamide 160 mg/day until disease progression, intolerable adverse events (AEs), or commercial availability occurred. AEs and other safety variables were assessed on day 1, weeks 4 and 12, and every 12 weeks thereafter. Data following transition to commercial drug were not collected. RESULTS: Median age was 71 years (range 43-97); 426 patients (83.9%) had a baseline ECOG score of ≤1. In addition to docetaxel, the majority of patients had received prior prostate cancer treatments such as abiraterone (76.1%) or cabazitaxel (28.6%). Median study treatment duration was 2.6 months (range 0.03-9.07). The most frequently reported reasons for discontinuation were commercial availability of enzalutamide (46.7%) and progressive disease (33.7%). A total of 88.2% of patients experienced AEs; 45.4% experienced AEs with a maximum grade of 1 or 2. Fatigue (39.1%), nausea (22.7%), and anorexia (14.8%) were the most commonly reported AEs. Seizure was reported in four patients (0.8%). The most commonly reported event leading to death was progression of metastatic prostate cancer (7.7%). CONCLUSION: In this heavily pretreated EAP population with progressive mCRPC, enzalutamide was well tolerated and the safety profile was consistent with that of the AFFIRM trial.

RESUMEN

Objectives: Molecular epidemiological description of an OXA-48 CPE outbreak affecting a tertiary-care hospital ward in Ireland over an extended period (2018-2019). Methods: Microbiological testing and whole-genome sequencing (WGS) were performed on all 56 positive OXA-48 outbreak case isolates. Results: In total, 7 different species were identified: Enterobacter hormaechei (n = 35, 62.5%), Escherichia coli (n = 12, 21.4%), Klebsiella pneumoniae (n = 5, 8.9%), Klebsiella oxytoca (n = 1, 1.8%), Klebsiella michiganensis (n = 1, 1.8%), Citrobacter freundii (n = 1, 1.8%), and Serratia marcesens (n = 1, 1.8%). E. hormaechei ST78 was the most common genotype (n = 14, 25%). Two major pOXA-48 plasmid types were identified throughout the outbreak, 'types' 1 and 2, and 5 major E. hormaechei clonal groupings were identified: ST78, ST108, ST1126, ST135, and ST66. Within each of the ST108, ST1126, ST135 and ST66 groups, the pOXA-48 harbored within each isolate were the same. Within ST78, 9 isolates contained the pOXA48 'type 2' plasmid and 5 contained the 'type 1' plasmid. Environmental specimens were taken from different outbreak ward locations: handwash basins, sink and shower drains, and taps. Of 394 environmental specimens, OXA-48 CPE was isolated from 26 (6.6%). Conclusions: This prolonged outbreak of OXA-48 CPE was confined to one ward, but it exemplifies the complexity and difficulty in the control of these organisms. With multiple species and genotypes involved, they may be better described as 'plasmid outbreaks.' WGS provided insights into this diversity and potential transmission among cases, though its usefulness would be enhanced by analysis as close as possible to real time so that interventions can be implemented as soon as data are available.

RESUMEN

PURPOSE: Epidermal growth factor receptor (EGFR) -tyrosine kinase inhibitors have proven efficacy in advanced non-small-cell lung cancer (NSCLC). We hypothesized that erlotinib would be efficacious in the adjuvant setting. PATIENTS AND METHODS: An international randomized, double-blind, placebo-controlled study was conducted in patients with completely resected IB to IIIA NSCLC whose tumors expressed EGFR protein by immunohistochemistry or EGFR amplification by fluorescence in situ hybridization. Patients were assigned 2:1 to erlotinib 150 mg once per day or placebo for 2 years. Stratification factors were stage, histology, previous adjuvant chemotherapy, smoking status, EGFR amplification status, and country. The primary end point was disease-free survival (DFS); key secondary end points were overall survival (OS) and DFS and OS in patients whose tumors had EGFR-activating mutations (EGFRm-positive). RESULTS: A total of 973 patients were randomly assigned (November 26, 2007, to July 7, 2010). There was no statistically significant difference in DFS (median, 50.5 months for erlotinib and 48.2 months for placebo; hazard ratio, 0.90; 95% CI, 0.74 to 1.10; P = .324). Among the 161 patients (16.5%) in the EGFRm-positive subgroup, DFS favored erlotinib (median, 46.4 v 28.5 months; hazard ratio, 0.61; 95% CI, 0.38 to 0.98; P = .039), but this was not statistically significant because of the hierarchical testing procedure. OS data are immature. Rash and diarrhea were common adverse events occurring in 528 (86.4%) and 319 (52.2%) patients treated with erlotinib, respectively, versus 110 (32.1%) and 54 (15.7%) patients receiving placebo. The most common grade 3 adverse events in patients treated with erlotinib were rash (22.3%) and diarrhea (6.2%). CONCLUSION: Adjuvant erlotinib did not prolong DFS in patients with EGFR-expressing NSCLC or in the EGFRm-positive subgroup. Further evaluation of erlotinib is warranted in the EGFRm-positive subgroup.
