Clostridium difficile infection (CDI) occurs in 3-7% of liver transplant recipients (LTR). However, few data exist on the recent epidemiology, predictors and outcomes of CDI in LTR. A cohort study was performed including LTR from 2000 to 2010 at a tertiary care hospital in Detroit. CDI was defined as diarrhea with a stool C. difficile positive test. Data analyzed included demographics, comorbidities, length of stay (LOS), severity of CDI, rates of recurrence (<12 weeks), relapse (<4 weeks) and overall mortality. Predictors of CDI were calculated using Cox proportional hazard model; 970 LTR were followed for years. Overall prevalence of CDI was 18.9%. Incidence of CDI within 1 year of transplant was 12.4%. Severe CDI occurred in 29.1%. CDI recurrence and relapse rates were 16.9% and 9.7%, respectively. Independent predictors of CDI were year of transplant (hazard ratio [HR] 1.137, 95% confidence interval [CI] 1.06-1.22; p < 0.001), white race (105/162 whites, HR 1.47, 95% CI 1.03-2.1; p ¼ 0.035), Model for End-Stage Liver Disease score (HR 1.03, 95% CI 1.01-1.045, p ¼ 0.003) and LOS (HR 1.01, 95% CI 1.005-1.02, p < 0.001). Significant mortality was observed among LTR with CDI compared to those without CDI (p ¼ 0.003). We concluded that CDI is common among LTR and is associated with higher mortality.

Background: Although gastric variceal (GV) bleeding is less common than esophageal variceal bleeding, the severity of GV bleeding is often greater with higher morbidity and mortality rates. Minimally invasive endovascular treatments such as balloon-occluded retrograde transvenous obliteration (BRTO) and transjugular intrahepatic portosystemic shunt (TIPS) have been used for the management of GVs with varying results, and individual and institutional differences exist in the use of BRTO and TIPS. We performed a systematic review and meta-analysis to compare the feasibility, efficacy, and safety of BRTO and TIPS for the treatment of GVs because of portal hypertension. Methods: Searches of PubMed, EMBASE, Google Scholar, and Cochrane Library databases were performed from inception through March 2019. Summary odds ratio (OR) with 95% confidence intervals (CI) was estimated for technical success, hemostasis rate, postprocedural complications, rebleeding rate, incidence of hepatic encephalopathy, and mortality rate at 1 year utilizing a random-effects model. Results: Seven studies with a total of 676 patients (BRTO: 462 and TIPS: 214) were included. There was no difference in pooled technical success rate (OR, 0.87; 95% CI, 0.28-2.73; P=0.81), hemostasis rate (OR, 2.74; 95% CI, 0.61-12.26; P=0.19), and postoperative procedure-related complications (OR, 1.95; 95% CI, 0.44-8.72; P=0.38). However, treatment with BRTO was associated with lower rates of postoperative rebleeding (OR, 0.30; 95% CI, 0.18-0.48; P<0.00001), postoperative encephalopathy (OR, 0.06; 95% CI, 0.02-0.15; P < 0.00001), and mortality at 1 year (OR, 0.43; 95% CI, 0.21-0.87; P=0.02). Conclusions: BRTO was associated with lower rates of rebleeding, postprocedure hepatic encephalopathy, and mortality at 1 year. BRTO should be considered first-line modality for the treatment of GVs because of portal hypertension.

Background:Inflammatory bowel disease (IBD) is a set of chronic inflammatory diseases associated with significant morbidity. Generally, IBD patients have twice the risk of venous thromboembolism (VTE) compared to healthy controls. VTE in IBD is associated with greater morbidity and mortality. This is compounded by the underutilization of pharmacological anticoagulation in hospitalized patients with IBD. One study showed that half the IBD patients who developed VTE were not receiving any thrombotic prophylaxis.Method:We carried out a retrospective chart review of VTE prophylaxis use and safety in patients admitted with IBD flare-up between 2014 and 2017.Results:We evaluated 233 patients (mean age 36.7 years; 53.6% male). Of these patients, 55.2% were Caucasian and 40.5% were African American; 72.5% had Crohn’s disease and 21% ulcerative colitis. About one-third of our patients were on chronic steroids. Pharmacological prophylaxis was used in 39.7% of the patients. This significantly correlated with male sex, recent surgery, history of VTE, smoking, and chronic steroid use. Meanwhile, hematochezia, aspirin use, and a history of gastrointestinal bleeding were correlated with less use of pharmacological prophylaxis. Patients receiving pharmacological prophylaxis showed no difference in the incidence of bleeding events.Conclusions:Multiple factors were associated with the use of pharmacological prophylaxis in hospitalized patients, including sex, steroid use, history of VTE events or gastrointestinal bleeding, and hematochezia. The incidence of major bleeding was not significantly greater in IBD patients receiving pharmacological prophylaxis.
