BACKGROUND & AIMS There are limited data on the prevalence or predictors of antibiotic-resistant bacterial infections (AR-BI) in hospitalized patients with cirrhosis in North America. Exposure to systemic antibiotics is a risk factor for AR-BI; however, little is known about the effects of the increasingly used oral nonabsorbed antibiotics. METHODS We analyzed data from patients with cirrhosis and bacterial infections hospitalized in a liver unit at a US hospital between July 2009 and November 2010. Multivariate logistic regression was used to determine predictors of AR-BI. Data were analyzed on the first bacterial infection of each patient (n = 115), and a sensitivity analysis was performed on all infectious episodes per patient (n = 169). RESULTS Thirty percent of infections were nosocomial. Urinary tract infections (32%) and spontaneous bacterial peritonitis (24%) were most common. Of the 70 culture-positive infections, 33 (47%) were found to be antibiotic resistant (12 were vancomycin-resistant Enterococci, 9 were extended-spectrum β-lactamase–producing Enterobacteriaceae, 7 were quinolone-resistant gram-negative rods, and 5 were methicillin-resistant Staphylococcus aureus). Exposure to systemic antibiotics within 30 days before infection was associated independently with AR-BI, with an odds ratio (OR) of 13.5 (95% confidence interval [CI], 2.6–71.6). Exposure to only nonabsorbed antibiotics (rifaximin) was not associated with AR-BI (OR, 0.4; 95% CI, 0.04–2.8). In a sensitivity analysis, exposure to systemic antibiotics within 30 days before infection and nosocomial infection was associated with AR-BI (OR, 5.2; 95% CI, 1.5–17.7; and OR, 4.2; 95% CI, 1.4–12.5, respectively). CONCLUSIONS The prevalence of AR-BI is high in a US tertiary care transplant center. Exposure to systemic antibiotics within 30 days before infection (including those used for prophylaxis of spontaneous bacterial peritonitis), but not oral nonabsorbed antibiotics, is associated with development of an AR-BI.

Background & Aims: Adult patients suffering from liver disease of unknown cause represent an understudied and underserved population. The use of whole-exome sequencing (WES) for the study of a broader spectrum of non-oncological diseases, among adults, remains poorly studied. We assessed the utility of WES in diagnosis and management of adults with unexplained liver disease despite comprehensive evaluation by a hepatologist and with no history of alcohol overuse. Methods: We performed WES and deep phenotyping of nineteen unrelated adult patients with idiopathic liver disease recruited at a tertiary academic health care center. Results: Analysis of the exome in 19 cases identified four monogenic disorders in five unrelated adults. Patient 1 suffered for 18 years from devastating complications of undiagnosed Type 3 Familial Partial Lipodystrophy due to a deleterious heterozygous variant in PPARG. Molecular diagnosis enabled initiation of leptin replacement therapy with subsequent normalization of liver

BACKGROUND Patients with cirrhosis deemed ineligible for liver transplantation are usually followed in general hepatology or gastroenterology clinics, with the hope of re-evaluation once they meet the appropriate criteria. Specific strategies to achieve liver transplant eligibility for these patients have not been studied. AIM To assess clinical and sociodemographic factors associated with future liver transplant eligibility among patients initially considered ineligible. METHODS This is a retrospective study of patients with cirrhosis considered non-transplant eligible, but without absolute contraindications, who were scheduled in our transitional care liver clinic (TCLC) after discharge from an inpatient liver service. Transplant candidacy was assessed 1 year after the first scheduled TCLC visit. Data on clinical and sociodemographic factors were collected. RESULTS Sixty-nine patients were identified and the vast majority were Caucasian men with alcoholic cirrhosis. 46 patients (67%) presented to the first TCLC visit. Seven of 46 patients that showed to the first TCLC visit became transplant candidates, while 0 of 23 patients that no-showed did (15.2% vs 0%, P = 0.08). Six of 7 patients who showed and became transplant eligible were accompanied by family or friends at the first TCLC appointment, compared to 13 of 39 patients who showed and did not become transplant eligible (85.7% vs 33.3%, P = 0.01). CONCLUSION Patients who attended the first post-discharge TCLC appointment had a trend for higher liver transplant eligibility at 1 year. Being accompanied by family or friends during the first TCLC visit correlated with higher liver transplant eligibility at 1 year (attendance by family or friends was not requested). Patient and family engagement in the immediate post-hospitalization period may predict future liver transplant eligibility for patients previously declined.
