An analysis of the outcomes of Clostridioides difficile occurring in intestinal transplant recipients requiring hospitalization.

BACKGROUND: Organ transplantation is a known risk factor for Clostridioides difficile infection (CDI). There is limited published data on the impact of CDI in the intestinal transplant population. METHODS: We utilized the National Readmission Database (2010-2017) to study the outcomes of CDI in patients having a history of intestinal transplantation. Association of CDI with readmission and hospital resource utilization was computed in multivariable models adjusted for demographics and comorbidities. RESULTS: During 2010-2017, 8442 hospitalizations with the history of intestinal transplantation had indexed hospital admissions. Of these, 320 (3.8%) had CDI. CDI hospitalization in intestine transplant patients was associated with higher median cost $54 430 (IQR: 27 231, 109 980) as compared to patients who did not have CDI $48 888 (IQR: 22 578, 112 777), (ß: 71 814 95% confidence intervals [CI]: 676-142 953, p = .048). The median length of stay was also longer for patients with CDI 7 (IQR: 4, 13) days as compared to 5 (IQR: 3, 11) days in non-CDI (ß: 5.51 95% CI: 0.73-10.29, p = .02). The mortality rate, intestinal transplant complications, presence of malnutrition, acute kidney injury, ICU admissions, and sepsis were similar in both groups. CDI was the top cause of 30-day readmission in the intestinal transplant recipients with CDI during the index admission; the number of 30-day readmissions also increased from 2010 to 2017. CONCLUSION: CDI hospitalization in post-intestine transplant patients occurs commonly and is associated with a longer length of stay and higher costs during hospitalization. The CDI was the most common cause of readmission after the index admission of CDI in these patients.

Band Ligation Can Be Used to Treat Barrett's Esophagus and Concurrent Esophageal Varices: A Case Series.

BACKGROUND: Patients with Barrett's esophagus (BE) and esophageal varices present a unique management dilemma. Endoscopic ablation and endoscopic resection are not suitable treatment options due to bleeding risk. Data are limited on successful eradication of BE and esophageal varices utilizing band ligation. AIMS: To assess the outcomes of patients with BE and esophageal varices treated with banding. METHODS: Retrospective analysis of patients with BE and esophageal varices who were treated with band ligation. RESULTS: A total of eight patients were included in the case series. In all eight cases, BE and esophageal varices were successfully treated with band ligation alone. There were no bleeding, perforation or infectious complications in any patients undergoing banding for treatment of BE. Four patients had biopsy-proven dysplasia prior to treatment with band ligation. After band ligation, the 2 of 4 dysplastic cases that had repeat biopsies showed histologic resolution of the dysplasia. All patients who received banding for BE were followed at least yearly except for one patient lost to follow up. No interval esophageal cancers were reported in any patients with BE that were banded. CONCLUSIONS: Band ligation was used to treat BE pathology in eight patients with esophageal varices. Treatment of dysplasia through this method yielded negative biopsies both for dysplasia and BE on repeat endoscopy. This case series highlights the value of utilizing band ligation to address the management dilemma of BE in the context of esophageal varices.

Heterogeneity in Center Practices in Liver Transplantation for Alcohol-Associated Liver Disease in the United States.

INTRODUCTION: Alcohol-related liver disease (ALD) is now the leading indication for liver transplantation (LT) in the United States (US). It remains unclear how centers are managing the medical and psychosocial issues associated with these patients. METHODS: We conducted a web-based survey of LT centers in the United States to identify center-level details on peri-LT management of ALD and related issues. RESULTS: Of the 117 adult LT centers, 100 responses (85.5%) were collected, representing all Organ Procurement and Transplantation Network regions. For alcohol-associated cirrhosis, 70.0% of the centers reported no minimum sobriety requirement while 21.0% required 6 months of sobriety. LT for severe alcohol-associated hepatitis was performed at 85.0% of the centers. Monitoring protocols for pre-LT and post-LT alcohol use varied among centers. DISCUSSION: Our findings highlight a change in center attitudes toward LT for ALD, particularly for severe alcohol-associated hepatitis.

Availability of PEth testing is associated with reduced eligibility for liver transplant among patients with alcohol-related liver disease.

BACKGROUND: Serum phosphatidylethanol (PEth) is a highly sensitive test to detect alcohol use. We evaluated whether the availability of PEth testing impacted rates of liver transplant evaluation terminations and delistings. METHODS: Medical record data were collected for patients who initiated transplant evaluation due to alcohol-related liver disease in the pre-PEth (2017) or PEth (2019) eras. Inverse probability weighting (IPW) was used to balance baseline patient characteristics. Outcomes included termination of evaluation or delisting due to alcohol use; patients were censored at receipt of transplant; death was considered a competing risk. The Fine-Gray method was performed to determine whether PEth testing affected risk of evaluation termination/ delisting due to alcohol use. RESULTS: Three hundred and seventy-five patients with alcohol-related indications for transplant (157 in 2017; 210 in 2019) were included. The final IPW-adjusted model for the composite outcome of terminations/delisting due to alcohol use retained two significant variables (P < .05): PEth era and BMI category. Patients evaluated during the PEth era were almost three times more likely to experience an alcohol-related termination/delisting than those in the pre-PEth era (sHR = 2.86; 95%CI 1.67-4.97) CONCLUSION: We found that availability of PEth testing at our institution was associated with a higher rate of exclusion of patients from eligibility for liver transplant. Use of PEth testing has significant potential to inform decisions regarding transplant candidacy for patients with alcohol-related liver disease.

Endoscopic Retrograde Cholangiopancreatography (ERCP) in Patients With Liver Cirrhosis: Analysis of Trends and Outcomes From the National Inpatient Sample Database.

GOALS: We aimed to assess outcomes of patients with liver cirrhosis who underwent therapeutic or diagnostic endoscopic retrograde cholangiopancreatography (ERCP) to determine whether these patients had different outcomes relative to patients without cirrhosis. BACKGROUND: ERCP is an important procedure for treatment of biliary and pancreatic disease. However, ERCP is relatively technically difficult to perform when compared with procedures such as esophagogastroduodenoscopy or colonoscopy. Little is known about how ERCP use affects patients with liver cirrhosis. STUDY: Using patient records from the National Inpatient Sample (NIS) database, we identified adult patients who underwent ERCP between 2009 and 2014 using International Classification of Disease, Ninth Revision coding and stratified data into 2 groups: patients with liver cirrhosis and those without liver cirrhosis. We compared baseline characteristics and multiple outcomes between groups and compared outcomes of diagnostic versus therapeutic ERCP in patients with cirrhosis. A multivariate regression model was used to estimate the association of cirrhosis with ERCP outcomes. RESULTS: A total of 1,038,258 hospitalizations of patients who underwent ERCP between 2009 and 2014 were identified, of which 31,294 had cirrhosis and 994,681 did not have cirrhosis. Of the patients with cirrhosis, 21,835 (69.8%) received therapeutic ERCP and 9459 (30.2%) received diagnostic ERCP. Patients with cirrhosis had more ERCP-associated hemorrhages (2.5% vs. 1.2%; P <0.0001) compared with noncirrhosis patients but had lower incidence of perforations (0.1% vs. 0.2%; P <0.0001) and post-ERCP pancreatitis (8.6% vs. 7%; P <0.0001). Cholecystitis was the same between groups (2.3% vs. 2.3%; P <0.0001). In patients with cirrhosis, those who received therapeutic ERCP had higher post-ERCP pancreatitis (7.9% vs. 5.1%; P <0.0001) and ERCP-associated hemorrhage (2.7% vs. 2.1%; P <0.0001) but lower incidences of perforation and cholecystitis (0.1% vs. 0.3%; P <0.0001) and cholecystitis (1.9 vs. 3.1%; P <0.0001) compared with those who received diagnostic ERCP. CONCLUSIONS: Use of therapeutic ERCP in patients with liver cirrhosis may lead to higher risk of complications such as pancreatitis and postprocedure hemorrhage, whereas diagnostic ERCP may increase the risk of pancreatitis and cholecystitis in patients with cirrhosis. Comorbidities in cirrhosis patients may increase the risk of post-ERCP complications and mortality; therefore, use of ERCP in cirrhosis patients should be carefully considered, and further studies on this patient population are needed.

The outcomes of Clostridioides difficile infection in inpatient liver transplant population.

BACKGROUND: Chronic immunosuppression is a known cause of Clostridioides difficile, which presents with colon infection. It is associated with increased mortality and morbidity. Our aim is to determine the inpatient outcomes of liver transplant patients with Clostridioides difficile infection (CDI) and trends in the last few years. METHODS: We utilized the national re-admission data (2010-2017) to study the outcomes of CDI in liver transplant patients. Association of C. difficile with re-admission was computed in a multivariable model adjusted for age, sex, gastrointestinal bleeding, hypertension, diabetes, hyperlipidemia, congestive heart failure, cerebrovascular disease, obesity, cancer, insurance, chronic kidney disease, chronic obstructive pulmonary disease, dementia, peripheral vascular disease, smoking, hospital location, and teaching status. RESULTS: During 2010-2017, there were 310 222 liver transplant patients hospitalized. Out of these, 9826 had CDI. CDI infection in liver transplant patients was associated with higher 30-day re-admission (14.3% vs. 11.21%, hazard ratio [HR]: 1.14, 95% confidence interval [CI]: 1.01-1.28, p = .02) and in-hospital mortality (odds ratio [OR]: 1.36, 95% CI: 1.14-1.61, p < .001). The most common causes of re-admission in the CDI group were recurrent CDI (41.1%), liver transplant complications (16.5%), and sepsis (11.6%). The median cost for liver transplant patients with C. difficile was significantly higher, $53 064 (IQR $24 970-$134 830) compared to patients that did not have C. difficile, $35 703 ($18 793-$73 871) (p < .001). The median length of stay was also longer for patients with CDI, 6 days (4-14) vs. 4 days (2-7) (p < .001). CONCLUSION: CDI in post-liver transplant patients was associated with higher mortality, re-admission, health care cost, and longer length of stay. The most common cause of re-admission was recurrent CDI, which raises the question of the efficacy of standard first-line therapy.

Efficacy and safety of mammalian target of rapamycin inhibitors following intestinal and multivisceral transplantation.

This is a descriptive study reviewing the outcomes of mammalian target of rapamycin inhibitors (mTORs) in intestinal (IT) and multivisceral transplantation (MVT). This study included 22 patients, 20 adults, and two children, and an overall mean age of 46 years old at the time of transplantation. Twelve patients (54.5%) received IT, and the remainder (45.5%) MVT. The mean time between transplantation and mTORs initiation was 24 months. The indication was worsening renal function in 13 patients (59%), with 9/13 (69.2%) noted to have an increase in glomerular filtration rate of at least 10 ml/min/1.73m2 . The indication for four patients (18.2%) was a history of neuroendocrine tumor. After mTOR initiation, 50% of patients were reduced or weaned off tacrolimus and 13.7% off prednisone. mTORs were discontinued in 11/22 patients. Six patients (54.5%) stopped due to side effects, two (18.1%) for surgery, and one (9%) for acute cellular rejection. Side effects were edema (33.3%), headaches (33.3%), diarrhea (16.7%), and oral ulcers (16.7%). The average duration of mTORs prior to discontinuation due to side effects was 7 months. mTORs may function in their own niche of patients due to the potential renal safety profile, but use is most limited by tolerance to side effects.

Peri-transplant lactate levels and delayed lactate clearance as predictive factors for poor outcomes after liver transplantation: A propensity score-matched study.

This study aimed to investigate risk factors for early allograft dysfunction (EAD) and outcomes after liver transplantation (LT), focusing on peri-transplant lactate clearance. We reviewed patients who underwent deceased donor LTs between 2011 and 2014. Lactate levels were checked at reperfusion and at the time of intensive care unit admission. Early lactate clearance was defined as reduction rate of lactate between the times of reperfusion and immediately after LT. Patients were categorized into the normal and delayed clearance groups. We used propensity score matching (PSM) between these two groups to estimate an impact of lactate clearance on incidence of EAD and graft survival. A total of 256 recipients were eligible for this study. Cut-off value of lactate clearance to predict occurrence of EAD was determined at 0.2 mmol/L/h. After PSM, 120 patients in the normal clearance and 36 patients in the delayed clearance group were matched. Delayed lactate clearance was considered as an independent risk factor for EAD (Odds ratio 3.49, P = 0.002). The adjusted hazard of one-year graft loss was significantly increased in the delayed clearance group (hazard ratio 6.69, P = 0.001). In conclusion, peri-transplant delayed lactate clearance may be a strong predictor for EAD and poor liver graft outcomes.

Daclatasvir combined with sofosbuvir or simeprevir in liver transplant recipients with severe recurrent hepatitis C infection.

Daclatasvir (DCV) is a potent, pangenotypic nonstructural protein 5A inhibitor with demonstrated antiviral efficacy when combined with sofosbuvir (SOF) or simeprevir (SMV) with or without ribavirin (RBV) in patients with chronic hepatitis C virus (HCV) infection. Herein, we report efficacy and safety data for DCV-based all-oral antiviral therapy in liver transplantation (LT) recipients with severe recurrent HCV. DCV at 60 mg/day was administered for up to 24 weeks as part of a compassionate use protocol. The study included 97 LT recipients with a mean age of 59.3 ± 8.2 years; 93% had genotype 1 HCV and 31% had biopsy-proven cirrhosis between the time of LT and the initiation of DCV. The mean Model for End-Stage Liver Disease (MELD) score was 13.0 ± 6.0, and the proportion with Child-Turcotte-Pugh (CTP) A/B/C was 51%/31%/12%, respectively. Mean HCV RNA at DCV initiation was 14.3 × 6 log10 IU/mL, and 37% had severe cholestatic HCV infection. Antiviral regimens were selected by the local investigator and included DCV+SOF (n = 77), DCV+SMV (n = 18), and DCV+SMV+SOF (n = 2); 35% overall received RBV. At the end of treatment (EOT) and 12 weeks after EOT, 88 (91%) and 84 (87%) patients, respectively, were HCV RNA negative or had levels <43 IU/mL. CTP and MELD scores significantly improved between DCV-based treatment initiation and last contact. Three virological breakthroughs and 2 relapses occurred in patients treated with DCV+SMV with or without RBV. None of the 8 patient deaths (6 during and 2 after therapy) were attributed to therapy. In conclusion, DCV-based all-oral antiviral therapy was well tolerated and resulted in a high sustained virological response in LT recipients with severe recurrent HCV infection. Most treated patients experienced stabilization or improvement in their clinical status.

Predictors of Thiopurine Treatment Failure in Biologic-Naïve Ulcerative Colitis Patients.

INTRODUCTION: Thiopurines (azathioprine and 6-mercaptopurine) have been used in the management of UC patients for over three decades. Nearly half of patients with UC treated with thiopurines fail to achieve remission or lose remission during treatment. Factors associated with thiopurine failure are poorly understood. The primary aim of our study was to investigate patient-related factors which are associated with thiopurine failure. METHODS: TNF-alpha antagonist-naïve patients with histological diagnosis of UC, receiving thiopurine therapy, with follow-up data from 1 to 3 years were included in the study. Data regarding demographics, laboratory results, and disease characteristics were collected. The primary endpoint was failure of thiopurine therapy, defined as treatment with steroids, therapeutic escalation to TNF-alpha antagonist therapy, or need for surgery. RESULTS: Of the 563 patients identified using ICD-9 codes, 78 TNF-alpha antagonist-naïve patients with a histological diagnosis of UC, receiving thiopurine treatment, were identified. Over the three-year follow-up period, 38 patients failed thiopurine treatment. On adjusted Cox regression, BMI < 25 kg/m(2) (HR 3, 95 % CI 1.55-5.83; p value = 0.001) was significantly associated with thiopurine failure. Furthermore, although not statistically significant, there was a strong trend toward thiopurine failure among patients with serum albumin level < 4 g/dL (HR 1.98, 95 % CI 0.97-4; p value = 0.06), non-smoking status (HR 2.2, 95 % CI 0.96-5.06; p value = 0.06), and higher degree of colon inflammation (HR 1.49, 95 % CI 0.96-2.32; p value = 0.08). DISCUSSION: Our results show that low body mass index is associated with increased risk of failure of thiopurine treatment. Furthermore, there was a strong trend toward thiopurine failure among patients with low serum albumin level (<4gm/dL). These factors should be considered as markers of non-response to thiopurine monotherapy for patients with moderately severe ulcerative colitis.

Persistent Reactive Thrombocytosis May Increase the Risk of Coronary Artery Disease Among Inflammatory Bowel Disease Patients.

BACKGROUND: IBD patients are at increased risk of coronary artery disease in the absence of traditional risk factors. However, the disease-related risk factors remain poorly understood although increased inflammation seems to increase cardiovascular disease risk in IBD. Thrombocytes are involved in the pathogenesis of coronary artery disease, and a subset of IBD patients have reactive thrombocytosis. AIM: The aim of our study was to investigate the effect of persistent reactive thrombocytosis on the development of coronary artery disease in IBD. METHODS: We evaluated a retrospective cohort of 2525 IBD patients who were evaluated at the Henry Ford hospital from 2000 to 2004. We performed a case-control study comparing patients with persistent thrombocytosis and patients without persistent thrombocytosis. Cases (n = 36) and controls (n = 72) were matched for age and gender. Coronary artery disease incidence was compared between the two groups. RESULTS: Cases (n = 36) and controls (n = 72) were matched for age and gender. Cases and controls were similar in age at onset of IBD (41.5 vs. 35.5, p value 0.11) and smoking status (33.3 vs. 27.8%, p value 0.66). Persistent thrombocytosis was less common among Caucasian patients (44.44 vs. 62.5%, p value 0.09) and more common in patients who had exposure to steroids during the study follow-up period. Coronary artery disease occurred in 13 (36.1%) patients with persistent thrombocytosis compared to only seven (9.7%) patients in the control group. CONCLUSIONS: Persistent reactive thrombocytosis among IBD patients is associated with increased risk of coronary artery disease. Further studies should characterize the clinical and molecular associations of this phenomenon and determine appropriate therapeutic measures.

Epidemiology and Management of Infections in Liver Transplant Recipients.

Background: Improvements in liver transplant (LT) outcomes are attributed to advances in surgical techniques, use of potent immunosuppressants, and rigorous pre-LT testing. Despite these improvements, post-LT infections remain the most common complication in this population. Bacteria constitute the most common infectious agents, while fungal and viral infections are also frequently encountered. Multi-drug-resistant bacterial infections develop because of polymicrobial overuse and prolonged hospital stays. Immediate post-LT infections are commonly caused by viruses. Conclusions: Appropriate vaccination, screening of both donor and recipients before LT and antiviral prophylaxis in high-risk individuals are recommended. Antimicrobial drug resistance is common in high-risk LT and associated with poor outcomes; epidemiology and management of these cases is discussed. Additionally, we also discuss the effect of coronavirus disease 2019 (COVID-19) infection and monkeypox in the LT population.

Falsely Elevated Tacrolimus (FK506) Trough Levels in a Liver Transplant Recipient.

Antibody-conjugated magnetic immunoassay (ACMIA) for tacrolimus (FK506) may detect falsely elevated tacrolimus trough levels, a commonly underreported event. We report a case of falsely elevated whole-blood tacrolimus levels in a patient post-orthotopic liver transplantation. A 71-year-old male patient underwent liver transplantation in 2012. Post-transplantation, the patient was immediately started on tacrolimus for maintenance immunosuppression. His most recent dose was 0.5 mg four times weekly. During monitoring, trough levels were at 25.9 ng/mL using ACMIA. After this result, a decision was made to hold tacrolimus. After holding tacrolimus for seven days, detected trough levels were still continually greater than 20 ng/mL. Upon suspicion of falsely elevated results, liquid chromatography with mass spectroscopy (LC-MS) was used to check tacrolimus trough levels. Results showed normal trough levels of 7.6 ng/mL. Because of its narrow therapeutic window, tacrolimus levels need to be carefully monitored throughout treatment. When high tacrolimus levels are detected using ACMIA without a correlating clinical scenario, trough levels should be re-confirmed using LC-MS to prevent clinical decisions from being made based on falsely elevated results.

Transplant hepatology and diversity: A decade-long analysis (2013-2022).

Diversity among physicians has been shown to positively impact patient care. Physicians from minority backgrounds are more likely to serve underserved communities and be involved in health disparities research. Efforts to increase the proportion of underrepresented minorities and women in medicine will help prepare a physician workforce that best cares for a diversifying nation. The purpose of this paper was to highlight trends in sex and ethnic representation among incoming U.S. transplant hepatology trainees over a 10-year period.

Timing and Complications of Intestinal Ostomy Takedown After Intestinal and Multivisceral Transplantation.

BACKGROUND: Ileostomies are typically created at the time of intestinal and multivisceral transplantation to assist in graft monitoring with endoscopy and biopsies. Often, these ostomies are reversed with a takedown procedure once there is stable graft function, but data are limited on associated complications of the takedown procedure for patients with intestinal transplants. METHODS: To assess complications associated with takedowns in this patient population, we performed a retrospective analysis of patients who had an intestinal transplant with elective ostomy takedown after transplant. No prisoners were used in the study and this manuscript is in compliance with the Helsinki Congress and the Declaration of Istanbul. RESULTS: A total of 16 patients, 10 isolated patients with intestinal transplants and 6 patients with multivisceral transplants, were included in the study, and takedown occurred at a mean of (236.8 ± 117.1) days after transplant. Of the 16 patients, 5 patients (31%) had uncomplicated courses after takedown with no infection, no rejection, and no hospital readmission within 3 months of takedown. The rest of the patients (69%) developed either infection or rejection within 3 months of takedown, and 1 patient died of infection after ileostomy takedown. CONCLUSION: This case series highlights the high risk of complications after ileostomy takedown for patients with intestinal transplants and contributes to the growing debate regarding the role of ileostomy creation and reversal in patients with intestinal transplants.

Pulmonary Complications of Everolimus in Liver Transplant Patients: A 10-Year Experience.

This retrospective study aims to evaluate the safety of everolimus when used as part of the immunosuppression regimen in patients who underwent liver transplant from 2009 to 2019 at a tertiary liver transplant center. Patients were divided into two groups: those who received everolimus as part of the post-transplant regimen and those who did not. The primary safety outcome measured was the development of new pulmonary complications that had been associated with everolimus use in prior studies. Lung function was determined by pulmonary function tests if available or CT scans of the chest. Secondary outcomes measured included everolimus discontinuation rates and survival rates. During the study period, 450 patients underwent liver transplant; 35% of patients received everolimus (n=156) and 65% of patients did not receive everolimus (n=292). Primary safety outcome of pulmonary complications was seen in 3.9% of patients who received everolimus (n=6) and 6.3% of the control group patients who did not receive everolimus (n=19). The association between everolimus use and new pulmonary complications was not significant with a chi-square statistic of 1.33 (p=0.249). Overall, 51.3% of patients who received everolimus during their post-transplant course discontinued the medication (n=80). Everolimus is safe from a pulmonary toxicity standpoint in liver transplant immunosuppression regimens as there was no significant difference found in pulmonary complications between patients who received the medication and those who did not.

Sepsis during short bowel syndrome hospitalizations: Identifying trends, disparities, and clinical outcomes in the United States.

BACKGROUND: Short bowel syndrome (SBS) hospitalizations are often complicated with sepsis. There is a significant paucity of data on adult SBS hospitalizations in the United States and across the globe. AIM: To assess trends and outcomes of SBS hospitalizations complicated by sepsis in the United States. METHODS: The National Inpatient Sample was utilized to identify all adult SBS hospitalizations between 2005-2014. The study cohort was further divided based on the presence or absence of sepsis. Trends were identified, and hospitalization characteristics and clinical outcomes were compared. Predictors of mortality for SBS hospitalizations complicated with sepsis were assessed. RESULTS: Of 247097 SBS hospitalizations, 21.7% were complicated by sepsis. Septic SBS hospitalizations had a rising trend of hospitalizations from 20.8% in 2005 to 23.5% in 2014 (P trend < 0.0001). Compared to non-septic SBS hospitalizations, septic SBS hospitalizations had a higher proportion of males (32.8% vs 29.3%, P < 0.0001), patients in the 35-49 (45.9% vs 42.5%, P < 0.0001) and 50-64 (32.1% vs 31.1%, P < 0.0001) age groups, and ethnic minorities, i.e., Blacks (12.4% vs 11.3%, P < 0.0001) and Hispanics (6.7% vs 5.5%, P < 0.0001). Furthermore, septic SBS hospitalizations had a higher proportion of patients with intestinal transplantation (0.33% vs 0.22%, P < 0.0001), inpatient mortality (8.5% vs 1.4%, P < 0.0001), and mean length of stay (16.1 d vs 7.7 d, P < 0.0001) compared to the non-sepsis cohort. A younger age, female gender, White race, and presence of comorbidities such as anemia and depression were identified to be independent predictors of inpatient mortality for septic SBS hospitalizations. CONCLUSION: Septic SBS hospitalizations had a rising trend between 2005-2014 and were associated with higher inpatient mortality compared to non-septic SBS hospitalizations.

Role of liver biopsy in the era of direct-acting antivirals.

An accurate assessment of the degree of fibrosis or presence of cirrhosis is critical both for the appropriate management of, and to provide prognosis for, patients with chronic hepatitis C infection. In the new era of direct acting antivirals, large numbers of patients may enter therapy, and although liver biopsy remains the gold standard, it is not practical in all settings. In recent years, a variety of noninvasive methods have been developed that may obviate the need for liver biopsy in most settings. Indirect laboratory formulas, tests, panels of biomarkers and imaging modalities may accurately stage the degree of fibrosis in hepatitis C monoinfection, hepatitis C/HIV coinfection, and post-transplant recurrent hepatitis C.

Transcatheter Aortic Valve Replacement Restoring Candidacy for Liver Transplant in Patients With Cirrhosis.

Guidelines for preoperative workup for an orthotopic liver transplant often rule out patients with severe aortic stenosis as transplant candidates. This case illustrates the potential of transcatheter aortic valve replacement (TAVR) as a bridge for liver transplants in cirrhotic patients with severe aortic stenosis. The 1-year and 2-year post-liver transplant follow-ups showed no complications in the patient's prosthetic aortic valves, and graft survival was 100% with no evidence of rejection. Notable post-transplant recovery involved medical complications that were not related to the liver function or surgical procedure.

Hepatitis C Cirrhosis, Hepatitis B Superimposed Infection, and the Emergence of an Acute Portal Vein Thrombosis: A Case Report.

Acute portal vein thrombosis (PVT) is a complication of liver cirrhosis. The presence of viral infections such as hepatitis B (HBV) and hepatitis C (HCV) can further increase cirrhotic patients' risk of developing PVT, especially in the rare case when there is superinfection with both HBV and HCV. We present a patient with HCV cirrhosis whose clinical condition was decompensated secondary to the development of superimposed HBV infection, who developed acute PVT during hospitalization. This case offers a unique presentation of acute PVT that developed within several days of hospitalization for decompensated liver disease, as proven by the interval absence of portal venous flow on repeat imaging. Despite the workup on the initial presentation being negative for PVT, reconsideration of differentials after the change in our patient's clinical status led to the diagnosis. Active HBV infection was likely the initial trigger for the patient's cirrhosis decompensation and presentation; the subsequent coagulopathy and alteration in the portal blood flow triggered the development of an acute PVT. The risk for both prothrombotic and antithrombotic complications remains high in patients with cirrhosis, a risk that is vastly increased by the presence of superimposedinfections. The diagnosis of thrombotic complications such as PVT can be challenging, thus stressing the importance of repeat imaging in instances where clinical suspicion remains high despite negative imaging. Anticoagulation should be considered for cirrhotic patients with PVT on an individual basis for both prevention and treatment. Prompt diagnosis, early intervention, and close monitoring of patients with PVT are crucial for improving clinical outcomes. The goal of this report is to illustrate diagnostic challenges that accompany the diagnosis of acute PVT in cirrhosis, as well as discuss therapeutic options for optimal management of this condition.
