Objective: To review the pharmacology, pharmacokinetics, efficacy, safety, and place in therapy of eravacycline, a novel fluorocycline antibiotic from the tetracycline family. Data Sources: A PubMed search was conducted for data between 1946 and March 2019 using MeSH terms eravacycline and TP-434. An internet search was conducted for unpublished clinical research. Study Selection and Data Extraction: The literature search was limited to English-language studies that described clinical efficacy, safety, and pharmacokinetics in humans and animals. Abstracts featuring prepublished data were also evaluated for inclusion. Data Synthesis: Eravacycline has in vitro activity against multidrug-resistant organisms, including methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus, extended-spectrum β-lactamase-producing and carbapenem-resistant Enterobacteriaceae, and Acinetobacter. It was approved for the treatment of complicated intra-abdominal infections (cIAIs) in adults following favorable results of 2 phase III trials, IGNITE 1 and IGNITE 4, compared with ertapenem and meropenem, respectively. The most common adverse drug events associated with eravacycline were infusion site reactions (7.7%), nausea (6.5%), vomiting (3.7%), and diarrhea (2.3%). Relevance to Patient Care and Clinical Practice: Eravacycline will likely be most useful for resistant infections when lack of tolerability, resistant phenotypes, or allergies prevent the use of β-lactams. Conclusions: Eravacycline is a new tetracycline antibiotic with a broad spectrum of activity that has demonstrated efficacy in the treatment of cIAIs. Although it has activity against multidrug-resistant organisms, data are limited for other indications.
Management of Coronavirus 2019 (COVID-19) with high-dose corticosteroids and interleukin-2 inhibitors has potential benefits, but is associated with immunosuppression and risk of secondary infections. This single-center, retrospective, cohort study evaluated the incidence of candidemia and associated risk factors in hospitalized COVID-19 patients. Twenty-three patients developed candidemia and were matched to 77 non-candidemic COVID-19 controls. The primary outcome was incidence of candidemia. Secondary outcomes included time to first positive fungal blood culture and antifungal initiation, antifungal treatment duration, fungal isolate identification, candidemia risk factors, in-hospital mortality, Intensive Care Unit (ICU) and hospital Length of Stay (LOS) and mechanical ventilation duration. Candidemia incidence was 0.7% (23/3101). Mean time from hospital admission to first positive fungal blood culture was 26.2±14.3 days, with systemic antifungal therapy initiated in 19 patients; seven started antifungal therapy the same day cultures were drawn and 12 within 24 h of preliminary culture results positive for yeast. The remaining four patients expired prior to culture results. Mean duration of antifungal therapy was 9.7±6.6 days. Candida albicans was the most frequently identified isolate. Candidemic patients were more likely to be admitted to the ICU, receive high-dose corticosteroid, renal replacement therapy, mechanical ventilation, central line, tocilizumab and broad-spectrum antimicrobials. They also had higher mortality (82% vs. 22%, p<0.0001) and longer ICU LOS (25 vs 0 days, p<0.0001), hospital LOS (39 vs 10 days, p<0.0001) and mechanical ventilation days (19 vs 0 days, p<0.0001). Candidemia occurrence is rare in COVID-19 patients, but can result in worse clinical outcomes such as high mortality and longer hospital stay. Clinicians should attempt to minimize risk factors and perform routine workup for systemic candida infections in COVID-19 patients in the ICU, on mechanical ventilation and with multiple risk factors.
Abdominal tuberculosis (TB) occurs only in a subset of TB-infected persons. With a higher incidence in the immunocompromised population, successful treatment includes early diagnosis and initiation of anti-TB medications. This case report discusses a 22-year-old immunocompetent male diagnosed with advanced duodenal and peritoneal TB after perforation requiring emergent surgery and intravenous anti-TB treatment secondary to lack of enteral access.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
