Abstract Background The relevance of vancomycin resistance in enterococcal blood stream infections (BSI) is still controversial. Aim of this study was to outline the effect of vancomycin resistance of Enterococcus faecium on the outcome of patients with BSI after orthotopic liver transplantation (OLT). Methods The outcome of OLT recipients developing BSI with vancomycin-resistant (VRE) versus vancomycin-susceptible Enterococcus faecium (VSE) was compared based on data extraction from medical records. Multivariate regression analyses identified risk factors for mortality and unfavourable outcomes (defined as death or prolonged intensive care stay) after 30 and 90 days. Results Mortality was similar between VRE- (n = 39) and VSE- (n = 138) group after 30 (p = 0.44) or 90 days (p = 0.39). Comparable results occurred regarding unfavourable outcomes. Mean SOFANon-GCS score during the 7-day-period before BSI onset was the independent predictor for mortality at both timepoints (HR 1.32; CI 1.14–1.53; and HR 1.18; CI 1.08–1.28). Timely appropriate antibiotic therapy, recent ICU stay and vancomycin resistance did not affect outcome after adjusting for confounders. Conclusion Vancomycin resistance did not influence outcome among patients with Enterococcus faecium bacteraemia after OLT. Only underlying severity of disease predicted poor outcome among this homogenous patient population. Trial registration This study was registered at the German clinical trials register (DRKS-ID: DRKS00013285).


摘要背景: 万古霉素耐药与肠球菌血流感染 (BSI) 的相关性仍存在争议。本研究的目的是概述屎肠球菌对万古霉素的耐药性对原位肝移植 (OLT) 后 BSI 患者预后的影响。方法根据病历资料提取,比较万古霉素耐药 (VRE) 与万古霉素敏感屎肠球菌 (VSE) OLT 受者发生 BSI 的结局。多变量回归分析确定了 30 天和 90 天后死亡率和不良结局 (定义为死亡或重症监护住院时间延长) 的危险因素。结果 30 后 VRE-(n = 39) 和 VSE-(n = 138) 组死亡率相似 (p = 0.44) 或 90 天 (p = 0.39)。关于不利结果出现了可比结果。BSI 发作前 7 天期间的平均 SOFANon-GCS 评分是两个时间点死亡率的独立预测因子 (HR 1.32; CI 1.14-1.53; HR 1.18; CI 1.08-1.28)。调整混杂因素后,及时适当的抗生素治疗、最近入住 ICU 和万古霉素耐药不影响结局。结论屎肠球菌菌血症患者 OLT 术后万古霉素耐药不影响预后。在这个同质患者人群中,只有潜在的疾病严重程度预测不良结局。试验注册本研究在德国临床试验注册中心 (DRKS-ID: DRKS00013285) 注册。

METHODS:BACKGROUND:Opioids are often prescribed for pain in cirrhosis and may increase the risk of hepatic encephalopathy (HE). AIMS:To assess the association between opioids and HE in patients with well-compensated cirrhosis. METHODS:We used the IQVIA PharMetrics (Durham, NC) database to identify patients aged 18-64 years with cirrhosis. We excluded patients with any decompensation event from 1 year before cirrhosis diagnosis to 6 months after cirrhosis diagnosis. Over the 6 months after cirrhosis diagnosis, we determined the duration of continuous opioid use and classified use into short term (1-89 days) and chronic (90-180 days). We assessed whether patients developed HE over the subsequent year (ie 6-18 months after cirrhosis diagnosis). We used a landmark analysis and performed multivariable Cox proportional hazards regression to assess associations between opioid use and HE, adjusting for relevant confounders. RESULTS:The cohort included 6451 patients with compensated cirrhosis, of whom 23.3% and 4.7% had short-term and chronic opioid prescriptions respectively. Over the subsequent year, HE occurred in 6.3% patients with chronic opioid prescriptions, 5.0% with short-term opioid prescriptions and 3.3% with no opioid prescriptions. In the multivariable model, an increased risk of HE was observed with short-term (adjusted hazard ratio, HR 1.44, 95% CI 1.07-1.94) and chronic opioid prescriptions (adjusted HR 1.83, 95% CI 1.07-3.12) compared to no opioid prescriptions. CONCLUSION:In this national cohort of privately insured patients with cirrhosis, opioid prescriptions were associated with the risk of incident HE. Opioid use should be minimised in those with cirrhosis and, when required, limited to short duration.

METHODS:BACKGROUND AND AIMS:Cirrhosis is characterized by extensive fibrosis of the liver and is a major cause of liver-related mortality. Cirrhosis is partially heritable but genetic contributions to cirrhosis have not been systemically explored. Here, we carry out association analyses with cirrhosis in two large biobanks and determine the effects of cirrhosis associated variants on multiple human disease/traits. METHODS:We carried out a genome-wide association analysis of cirrhosis as a diagnosis in UK BioBank (UKBB; 1088 cases vs. 407 873 controls) and then tested top-associating loci for replication with cirrhosis in a hospital-based cohort from the Michigan Genomics Initiative (MGI; 875 cases of cirrhosis vs. 30 346 controls). For replicating variants or variants previously associated with cirrhosis that also affected cirrhosis in UKBB or MGI, we determined single nucleotide polymorphism effects on all other diagnoses in UKBB (PheWAS), common metabolic traits/diseases and serum/plasma metabolites. RESULTS:Unbiased genome-wide association study identified variants in/near PNPLA3 and HFE, and candidate variant analysis identified variants in/near TM6SF2, MBOAT7, SERPINA1, HSD17B13, STAT4 and IFNL4 that reproducibly affected cirrhosis. Most affected liver enzyme concentrations and/or aspartate transaminase-to-platelet ratio index. PheWAS, metabolic trait and serum/plasma metabolite association analyses revealed effects of these variants on lipid, inflammatory and other processes including new effects on many human diseases and traits. CONCLUSIONS:We identified eight loci that reproducibly associate with population-based cirrhosis and define their diverse effects on human diseases and traits.

METHODS:BACKGROUND:Spontaneous bacterial peritonitis (SBP) is a serious complication in patients with liver cirrhosis. In recent years, it has been postulated that the rate of multidrug-resistant organisms (MDROs) is increasing, especially in nosocomial SBP patients. Aim of the present work was to investigate this hypothesis and its possible clinical consequences. MATERIALS AND METHODS:One hundred and three culture-positive patients between 2007 and 2014 were compared with 81 patients between 2015 and 2017, to study the change of microbiological profiles and their clinical consequences. The cirrhosis patients with bacterascites requiring treatment were included as well. RESULTS:The most prevalent Gram-negative bacteria isolated from ascites were Enterobacterales (31.6%) and in Gram-positive pathogens Staphylococci (22.8%). There was a significant increase in MDROs (22.3% ICU 40.7%, P = .048), accompanied by an increased incidence of sepsis (from 21.4% to 37.0%, P = .021), hepatorenal syndrome (from 40.8% to 58.0%, P = .007) and the need of catecholamine therapy (from 21.4% to 38.8%, P = .036). Nosocomial origin correlated with higher MDRO proportion, more complications and lower antimicrobial susceptibility rates in 12 commonly used antibiotics. MDROs were confirmed as an isolated predictor for inpatient mortality and complications in multivariable logistic regression. CONCLUSIONS:The feeling in clinical practice that MDROs have increased in the last 11 years could be confirmed in our study in Munich, Germany. Nosocomial SBP correlated with significantly higher MDRO rates (nearly 50%) and complication rates. In our opinion, an antibiotic combination with comprehensive effect should be taken into account in nosocomial SBP patients in this region.
