Besides adequate antibiotics and infectious source control, definitive therapy is still being studied. The activation of multiple pro- and anti-inflammatory mediators plays a key role in the sepsis process. The application of adsorption may help deactivate and decrease the peak elevation of these mediators in the earlier course of sepsis, when levels of endotoxins and cytokines are extremely high. However, the clinical evidence to support hemadsorption for removing endotoxins and/or pro-inflammatory mediators in sepsis remains incompetent and controversial. In this study protocol, we aimed to test the efficacy of removing cytokines and the safety of a new hemadsorption device, CA330, in septic patients. <strong>Design:</strong> This is a multicenter randomized controlled clinical trial enrolling 8 tertiary hospitals in China. A total of 144 patients will be randomly divided into the experimental group and the control group according to the ratio of 1:1. The primary endpoint is the reduction rate of IL-6 serum concentration between the initiation of the first adsorption and end with the second adsorption. <strong>Discussion:</strong> To our knowledge, this clinical trial is the first to evaluate the efficacy and safety of the CA330 hemadsorption device in sepsis patients. Our study will raise the level of evidence for the treatment of sepsis patients with hemadsorption.展开更多

METHODS: A retrospective, observational study enrolled cIAIs patients hospitalized in The First Affiliated Hospital, Sun Yat-sen University from January 1, 2013 to June 30, 2017 was conducted. Patients’ data were collected and matched based on age, gender, and Acute Physiologic Assessment and Chronic Health Evaluation II (APACHE II) score according to receiving first-line, later-line, or no tigecycline during hospitalization. RESULTS: Data were collected for 52 patients. 82.6% were male. Mean age was 57.8 years and APACHE II score was 14.8. The incidence of both extended-spectrum beta-lactamase producing and carbapenem-resistant pathogens was high on initial culture;however, few patients received first-line tigecycline. No significant difference in mortality rate was identified among first-line, later-line and no tigecycline users. Of surviving patients, shorter hospital length of stay was observed for patients receiving first- vs later-line or no tigecycline, respectively. ICU length-of-stay was shorter in patients receiving first- vs later-line or no tigecycline. CONCLUSIONS: First-line tigecycline use was rare in our surgical intensive care unit. Resistant organisms were commonly cultured from initial specimens. Although these results are limited by small patient numbers and single center, our results suggest that early tigecycline use may have significant benefits with similar mortality. Further research is warranted to demonstrate the values of early tigecycline use in cIAIs patients.展开更多
