Previous large registry studies have demonstrated inferior outcomes for simultaneous liver‐kidney transplantation (SLKT) recipients of grafts from donation after circulatory death (DCD) donors compared with those from donation after brain death (DBD) donors in the era from 2000 to 2010. Given the improving national results in liver transplantation alone using grafts from DCD donors, the present study aimed to investigate if results with DCD‐SLKT have improved in the modern era. Patients undergoing SLKT between 2000 and 2018 were obtained from the United Network for Organ Sharing Standard Analysis and Research file and divided into 2 eras based on the date of SLKT: era 1 (2000‐2010) and era 2 (2011‐2018). Improvement in DCD‐SLKT patient, liver graft, and kidney graft survival rates was seen between era 1 and era 2 (P < 0.001). Concurrently, there was a decrease in the proportion of critically ill (P = 0.02) and retransplant (P = 0.006) candidates undergoing DCD‐SLKT. When DCD‐SLKT in era 2 was compared with a propensity‐matched cohort of DBD‐SLKT in era 2, no differences in patient (P = 0.99), liver graft (P = 0.19), or kidney graft (P = 0.90) survival were observed. In addition, both bilirubin (0.5 versus 0.5 mg/dL; P = 0.86) and creatinine (1.2 versus 1.2 mg/dL; P = 0.68) at last follow‐up were not different between the DCD‐SLKT and DBD‐SLKT patients in era 2. In conclusion, in the most recent era, patients undergoing DCD‐SLKT were able to achieve similar outcomes compared with matched patients undergoing DBD‐SLKT. DCD‐SLKT represents a viable option for appropriately selected recipients.

Objectives Recent studies have suggested that small intestinal bacterial overgrowth (SIBO) could be a predisposing factor for nonalcoholic fatty liver disease (NAFLD) although the results were inconsistent. This systematic review and meta-analysis was conducted with the aim to summarize all available data. Methods A comprehensive literature review was conducted utilizing MEDLINE and EMBASE databases through September 2018 to identify all studies that compared the risk of NAFLD among patients with SIBO versus those without SIBO. Effect estimates from each study were extracted and combined together using the random effect, generic inverse variance method of DerSimonian and Laird. Results A total of 10 studies with 1093 participants fulfilled the eligibility criteria and were included in the meta-analysis. A significant association between NAFLD and SIBO was observed with the pooled odds ratio of 3.82 (95% confidence interval, 1.93–7.59; I 2 65%). Funnel plot is relatively symmetric and is not suggestive of the presence of publication bias. Conclusion A significant association between NAFLD and SIBO was observed in this meta-analysis.

Background. The present multicenter study investigated whether equivalent outcomes to primary liver transplant (LT) could be achieved with liver retransplant (reLT) and whether improvements in outcomes have taken place over time, particularly in the direct-acting antiviral era. Methods. All reLT performed at Mayo Clinic Florida, Mayo Clinic Rochester, and Mayo Clinic Arizona were divided into era 1 (2002–2007), era 2 (2008–2012), and era 3 (2013–2017) based on the date of reLT. Results. Improvement in graft survival (GS) after reLT was seen over the 3 eras (P < 0.001). In era 1, GS after reLT was inferior to primary LT (P < 0.001), whereas no difference was seen between reLT and primary LT in era 2 (P = 0.68) or era 3 (P = 0.36). A significantly higher proportion of patients achieved sustained viral response (SVR) within the first year after reLT in each subsequent era (era 1: 10.3%, era 2: 22.5%, and era 3: 100%) (P < 0.001). Graft survival was superior in patients undergoing reLT for recurrent hepatitis C virus who achieved SVR after reLT compared with those who did not (P = 0.03). Conclusions. Results similar to primary LT were achieved in era 3. These improvements coincide with the availability of direct-acting antivirals, which resulted in a 100% SVR rate in era 3 and a decrease in the number of patients undergoing reLT for recurrent hepatitis C virus. The historic dogma that reLT results in inferior outcomes should be revisited.

Background/ObjectivesA negative association between cigarette smoking and celiac disease has been observed but results were inconsistent across the published studies. A meta‐analysis was conducted with the aim to identify all studies that investigated this association and to summarize the results of those studies.MethodsA comprehensive literature review was conducted utilizing MEDLINE and Embase databases through March 2018 to identify all cohort studies and case‐control studies that compared the risk of celiac disease among current and/or former smokers versus never‐smokers. Effect estimates from each study were extracted and combined together using the random‐effect, generic inverse variance method of DerSimonian and Laird.ResultsA total of seven studies with 307,924 participants fulfilled the eligibility criteria and were included in the meta‐analysis. The pooled analysis found a significantly decreased risk of celiac disease among current smokers compared with never‐smokers with the pooled odds ratio (OR) of 0.52 (95% confidence interval (CI), 0.32–0.84; I2 86%). However, the risk of celiac disease among former smokers was not significantly different from never‐smokers with the pooled OR of 1.10 (95% CI, 0.76–1.60; I2 of 73%).ConclusionsA significantly decreased risk of celiac disease among current smokers compared with never‐smokers was demonstrated in this meta‐analysis.

Background/objectives The relationship between nonalcoholic fatty liver disease (NAFLD) and albuminuria has been shown in many epidemiologic studies, although the results were inconsistent. This meta-analysis was conducted to summarize all available data and to estimate the risk of albuminuria among patients with NAFLD. Methods Comprehensive literature review was conducted utilizing Medline and Embase database through January 2018 to identify studies that compared the risk of albuminuria among patients with NAFLD versus those without NAFLD. Effect estimates from each study were extracted and combined using the random-effect, generic inverse variance method of DerSimonian and Laird. Results Nineteen studies (17 cross-sectional studies and two cohort studies) with 24 804 participants fulfilled the eligibility criteria and were included in this meta-analysis. The risk of albuminuria among patients with NAFLD was significantly higher than those without NAFLD with the pooled odds ratio (OR) of 1.67 [95% confidence interval (CI): 1.32–2.11]. Subgroup analysis demonstrated the significantly increased risk of albuminuria among patients with NAFLD without diabetes with pooled OR of 2.25 (95% CI: 1.65–3.06). However, we found no significant association between albuminuria and NAFLD among diabetic patients [pooled OR 1.28 (95% CI: 0.94–1.75)]. Conclusion A significantly increased risk of albuminuria among patients with NAFLD was observed in this meta-analysis. Physicians should pay more attention to the early detection and subsequent treatment of individuals with microalbuminuria especially in patients with NAFLD.

Background/ObjectivesStudies have suggested that smokers may have a lower risk of primary sclerosing cholangitis (PSC) although the results have been inconsistent. This systematic review and meta‐analysis was conducted to summarize all available data to better characterize this association.MethodsA comprehensive literature review was conducted using Medline and Embase databases through January 2018 to identify all studies that compared the risk of PSC among current/former smokers versus nonsmokers. Effect estimates from each study were extracted and combined using the random‐effect, generic inverse variance method of DerSimonian and Laird.ResultsSeven case‐control studies with 2,307,393 participants met the eligibility criteria and were included in the meta‐analysis. The risk of PSC among current smokers and former smokers was significantly lower than nonsmokers with the pooled odds ratio of 0.31 (95% CI, 0.18–0.53) and 0.52 (95% CI, 0.44–0.61), respectively. The risk remained significantly lower among current smokers and former smokers compared with nonsmokers even when only patients with PSC without inflammatory bowel disease were included.ConclusionsA significantly decreased risk of PSC among current and former smokers was demonstrated in this study.

The tragedy of the national opioid epidemic has resulted in a significant increase in the number of opioid‐related deaths and accordingly an increase in the number of potential donors designated Public Health Service (PHS) increased risk. Previous studies have demonstrated reluctance to use these PHS organs, and as a result, higher discard rates for these organs have been observed. All patients listed for liver transplantation in the United States from January 2005 to December 2016 were investigated. Patients on the waiting list were divided into 2 groups: those in which a PHS liver was used for transplantation (accepted PHS group) and those in which a PHS liver was declined and transplanted into a recipient lower on the match run (declined PHS group). Intention‐to‐treat patient survival from the time of PHS offer was significantly higher in the accepted PHS compared with the declined PHS group (P < 0.001). On Cox multivariate regression, declining a PHS donor liver was associated with a hazard ratio of 2.36 (95% confidence interval, 2.23‐2.49; P < 0.001). For patients in which a PHS organ offer was declined, 11.6% died or were delisted for being too sick within the subsequent year. Donor liver allografts implanted in the accepted PHS group were of a lower donor risk index (1.28 versus 1.44) compared with the non‐PHS organs that patients in the declined PHS group ultimately received if they underwent transplantation. In conclusion, there is a significantly higher survival for patients in which a PHS liver is accepted and used compared with those patients in which a PHS organ is declined. These data will help inform decisions about whether or not to accept a PHS donor liver for both patients and transplant professionals. Liver Transplantation 24 497–504 2018 AASLD.

AbstractGraft‐versus‐host disease (GVHD) is a rare, fatal complication following orthotopic liver transplantation (OLT). To date, several risk factors have been proposed, but reports on these factors have been inconclusive. This is a retrospective, case–control study of prospectively collected data from 2775OLTs performed at our institution. Eight cases ofGVHDafterOLTwere diagnosed on the basis of the patient's clinical characteristics, and the findings were confirmed with skin and colonic biopsies. Each case was matched to three controls based on the diagnosis of liver disease, recipient's age, and blood group. Univariate and multivariate analyses were performed to identify risk factors associated with the development ofGVHDafterOLT. The univariate and multivariate analyses identified two main risk factors associated with development ofGVHDinOLTrecipients, a difference between recipient and donor age of >20 yr, and any human leukocyte antigen classImatches. Taking these two risk factors into consideration while matching prospective donors and recipients may reduce further incidence ofGVHDinOLTpatients. However, further studies are recommended to validate these findings.
