RESUMEN

No guidelines currently exist for the management of Candida auris bloodstream infection in patients with left ventricular assist devices (LVADs). We aim to share our management experience through this retrospective case series outlining 15 episodes of C auris candidemia identified in 7 patients over 18 months. The initial source of candidemia was central venous catheter in 5 patients, driveline exit site infection in 1 patient, and possible pump infection in 1 patient. All patients were initially treated with micafungin. Despite susceptibility to micafungin, 4 patients experienced recurrent C auris candidemia. All patients died within 1 year of their first episode of C auris candidemia. Source control is challenging in patients with LVADs, and strict infection prevention measures should be practiced. More studies are needed to evaluate the role of newer antifungal agents, use of combination antifungal regimens, and impact on morbidity in patients with LVADs.

RESUMEN

Viral infections have multiple mechanisms of affecting internal and external organs by direct invasion or by molecular mimicry. They have also been described as triggers for inflammatory processes like hyperinflammatory syndrome (HIS), Adult-onset Stills Disease (AOSD), and myocarditis [1]. Here we report an interesting case of a young adult with recent infection with SARS-CoV-2 (COVID-19) who presented with myocarditis requiring circulatory support in the cardiac care unit. During the admission, he was found to have concurrent cytomegalovirus (CMV) mononucleosis syndrome and presentation consistent with HIS resembling AOSD. This patient had multiple etiologies that could have caused myocarditis: CMV infection, COVID-19 infection, and HIS. As noted, viral infections have been proposed as potential triggers for the onset of HIS and AOSD with unknown mechanisms. We aim to add to the literature regarding CMV infection in an immunocompetent host causing myocarditis and HIS with features of AOSD with recent history of COVID-19 infection.

RESUMEN

Antimicrobial stewardship programs play a critical role in optimizing the use of antimicrobials against pathogens in the era of growing multi-drug resistance. However, implementation of antimicrobial stewardship programs among the hematopoietic stem cell transplant and oncology populations has posed challenges due to multiple risk factors in the host populations and the infections that affect them. The consideration of underlying immunosuppression and a higher risk for poor outcomes have shaped therapeutic decisions for these patients. In this multidisciplinary perspective piece, we provide a summary of the current landscape of antimicrobial stewardship, unique challenges, and opportunities for unmet needs in these patient populations.

RESUMEN

CONTEXT: Metastatic bone disease is a commonly encountered problem in oncology practice. The most useful and cost effective treatment is radiotherapy (RT). Different fractionation schedule of RT can be used to treat such condition. AIMS: Assessment of pain response in patients with vertebral bone metastasis after treating them with various radiation fractionations and to compare the toxicity profile in the treatment arms. SETTINGS AND DESIGN: A prospective randomized study was designed to include total 64 patients from July 2010 to May 2011. Patients with histopathologically proven primary malignancy having symptomatic secondary deposits to vertebra were selected for the study. Patients were randomized to two arms receiving multiple fraction of RT with 30 Gy in 10 fractions and 8 Gy in single fraction RT, respectively. MATERIALS AND METHODS: Patients with age >75 years, Karnofsky Performance Status (KPS) <40, features of cord compression were excluded from study. Initial pain response was assessed using Visual Analogue Scale (VAS) and compared using the same scale at weekly interval up to 1 month after treatment completion. RESULTS: Arm A comprised of 33 patients while 31 patients were enrolled in Arm B. Baseline patient characteristics were comparable. Eleven patients were lost to follow-up. Initial pain scores were 7.23 ± 0.765 and 7.51 ± 0.55 in arm A and arm B, respectively. Pain scores reduced significantly in both the arms after 1 month (4.39 ± 1.82 in arm A; 5.25 ± 2.39 in arm B). Time of initiation of pain response was earlier in arm A (P = 0.0281), statistically significant. Mild G-I toxicity was noted in both the arms but differences in two arms were not statistically significant (P = 0.49), no interruption of treatment was required because of side effects. CONCLUSIONS: Different fractionation of radiation has same response and toxicity in treatment of vertebral bone metastasis. Single fraction RT may be safely used to treat these cases as this is more cost effective and less time consuming. Studies may be conducted to find out particular subgroup of patients to be benefitted more by either fractionation schedule; however, our study cannot comment on that issue.

RESUMEN

OBJECTIVE: We analyzed the effects of different cefepime MIC breakpoints on Enterobacteriaceae cefepime susceptibility and the presence of AmpC and extended-spectrum ß-lactamase (ESBL) genes within the cefepime MIC interpretative categories. METHODS: Using Enterobacteriaceae susceptibility data from 2013 comparisons of MIC breakpoints were performed using Pearson's chi-squared test. Molecular testing on a subset of isolates was done. RESULTS: Among 3784 non-duplicate clinical isolates, cefepime susceptibility decreased from 97.6% to 96.1% to 93.7% for CLSI 2013, CLSI 2014, and EUCAST 2011, respectively. In ceftriaxone non-susceptible isolates, cefepime susceptibility decreased from 79% to 66% (P<0.0001) using CLSI 2013 and 2014, respectively, which was greater and statistically significant for Escherichia coli and Klebsiella spp. but not for Enterobacter spp. (P=0.06). Isolates with MIC ≤1µg/mL more often harbored AmpC (77%) than ESBL (18%) genes. CONCLUSIONS: Lower cefepime MIC breakpoints decrease cefepime susceptibility for isolates harboring ESBLs, while sparing the majority of those with AmpCs.
