Abstract

BACKGROUND:The use of elderly donors (≥60 years) in living-donor liver transplantation (LDLT) remains controversial. In this study, we aimed to determine the safety of surgery for elderly donors and the impact of donor age on LDLT outcomes. METHODS:We retrospectively reviewed 470 cases of LDLT at Kumamoto University Hospital from December 1998 to March 2017. RESULTS:Donors were divided into 5 groups according to age: 20-29 (n=109), 30-39 (n=157), 40-49 (n = 87), 50-59 (n = 81), and ≥60 (n = 36). At our institution, elderly donor candidates required additional preoperative work-up. There were no significant differences in the incidence of postoperative complications and duration of postoperative hospital stay among the 5 donor groups. Regardless of graft type, elderly donors were comparable to younger donor groups (<30 years) in postoperative recovery of liver function. Risk-adjusted overall survival rates of recipients among donor groups were not significantly different. Additionally, donor age was not significantly associated with 6-month graft survival of adult and pediatric recipients. CONCLUSIONS:Elderly candidates ≥60 years of age can safely be selected as LDLT donors after meticulous preoperative work-up.

摘要

背景: 在活体肝移植 (LDLT) 中使用老年供体 (≥ 60 岁) 仍存在争议。在本研究中,我们旨在确定老年供体手术的安全性以及供体年龄对 LDLT 结局的影响。 方法: 我们回顾性分析了 1998年12月至 2017年3月熊本大学医院 470 例 LDLT。 结果: 供体按年龄分为 5 组: 20-29 (n = 109),30-39 (n = 157),40-49 (n = 87), 50-59 (n = 81),≥ 60 (n = 36)。在我们机构,老年供体候选人需要额外的术前检查。5 个供体组的术后并发症发生率和术后住院时间无显著差异。无论移植物类型如何,老年供体在术后肝功能恢复方面与年轻供体组 (<30 岁) 相当。供体组间受者的风险调整总生存率无显著差异。此外,供体年龄与成人和儿童受者的 6 个月移植物存活率无显著相关性。 结论: 年龄 ≥ 60 岁的老年候选人在经过细致的术前检查后可以安全地选择为 LDLT 供体。

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.
