RESUMEN

Given the need to improve the sensitivity of non-invasive methods to detect colorectal neoplasia, particularly adenomas, we compared a fecal test using a monoclonal antibody (Mab) raised against constituents of colonic adenomas designated Adnab-9 (Adenoma Antibody 9), recognizing an N-linked 87 kDa glycoprotein, to gFOBT, which is shown to reduce CRC mortality. p87 immunohistochemistry testing is significantly more sensitive (OR 3.64[CI 2.37-5.58]) than gFOBT (guaiac-based fecal occult blood test) for adenomas (<3 in number), advanced adenomas (OR 4.21[CI 2.47-7.15]), or a combination of the two (OR 3.35[CI 2.47-4.53]). p87 immunohistochemistry shows regional Paneth cell (PC) expression mainly in the right-sided colon and is significantly reduced in the ceca of African Americans (p < 0.0001). In a subset of patients, we obtained other body fluids such as urine, colonic effluent, and saliva. Urine tests (organ-specific neoantigen) showed a significant difference for advanced adenomas (p < 0.047). We conclude that fecal p87 testing is more sensitive than gFOBT and Adnab-9 and could be used to better direct the colonoscopy screening effort.

RESUMEN

BACKGROUND: The prognosis of acute kidney disease (AKD), defined as a glomerular filtration rate of <60 ml/min/1.73 m2 or a rise in serum creatinine (sCr) of <50% for <3 months, is not clearly known. AIM: To study the prevalence, predictive factors and clinical outcomes in hospitalized cirrhotic patients with AKD. METHODS: The North American Consortium for the Study of End-Stage Liver Disease prospectively enrolled hospitalized decompensated cirrhotic patients. Patients were separated into those with normal renal function (controls or C), AKD or stage 1 AKI as their worst renal dysfunction per International Club of Ascites definition and compared. Parameters assessed included demographics, laboratory data, haemodynamics, renal and patient outcomes. RESULTS: 1244 patients with cirrhosis and ascites (C: 704 or 57%; AKD: 176 or 14%; stage 1 AKI: 364 or 29%) with similar demographics were enrolled. AKD patients had similar baseline sCr but higher hospital admission in the previous 6 months, and higher peak sCr, compared to controls, with their peak sCr being lower than that in stage 1 AKI patients (all P < .0001). The in-hospital and 30-day survival for AKD patients were intermediary between that for controls and stage 1 AKI patients (96% vs 91% vs 86%, P < .0001). The strongest predictors for AKD development while in hospital were the presence of a second infection (OR: 2.44) and diabetes (OR: 1.53). CONCLUSIONS: Patients with AKD had intermediate outcomes between stage 1 AKI and controls. AKD patients, especially those with diabetes and a second infection, need careful monitoring and prompt treatment for AKD to prevent negative outcomes.

RESUMEN

BACKGROUND & AIMS: Insurance, race, and ethnicity can affect outcomes of patients with cirrhosis, but findings from prospective studies are unclear. We investigated the role of insurance status and race and ethnicity (race/ethnicity) on inpatient and 90-day postdischarge outcomes in a large inpatient cohort of patients with cirrhosis. METHODS: We used data from the North American Consortium for the Study of End-Stage Liver Disease (NACSELD) database, from 13 tertiary care centers. Insurance status (uninsured, Medicare, Medicaid, private, and Canadian), race, and ethnicity, were analyzed independent of clinical covariates for their association with transfer to the intensive care unit, acute on chronic liver failure (ACLF), length of hospital stay, inpatient and 90-day death or liver transplantation, and readmission to the hospital within 90 days. Multi-variable analyses and interaction terms were created for insurance, race/ethnicity, and for each outcome, with or without Canadian patients. RESULTS: We analyzed data from 2640 patients in the NACSELD database (971 with private insurance, 770 with Medicare, 456 Canadians, 265 with Medicaid, 178 uninsured, 540 non-Caucasian and 220 Hispanic); 23% required admittance to the intensive care unit, 12% developed NACSELD-defined ACLF, 7% died, 5% underwent liver transplantation. Of the 2288 patients discharged from hospital, 13% underwent liver transplantation, 19% died, and 42% were readmitted within 90 days. In the univariate model, uninsured patients accounted for the highest percentage of alcohol- or bleeding-related admissions and the lowest proportion of outpatient cirrhosis-related medication users. Canadians had the lowest rifaximin use and but higher proportions had hepatic encephalopathy, compared with other groups. Lack of insurance was higher among non-Caucasians, regardless of Hispanic ethnicity. In multi-variable analysis, lack of insurance was associated with ACLF (P = .02) and inversely associated with inpatient liver transplant (P = .05) and 90-day liver transplant (P = .02), regardless of whether Canadians were included or specific insurance type. Race or ethnicity were not significantly associated with outcomes. CONCLUSIONS: In analyzing the NACSELD database, we found that insurance status, but not race or ethnicity, were independently associated with ACLF and inpatient or 90-day liver transplantation, regardless of inclusion of Canadian patients.

RESUMEN

BACKGROUND & AIMS: Progression of stages 2 and 3 acute kidney injury (AKI) in cirrhosis has not been characterized adequately. Patients with higher stages of AKI are believed to have worse outcomes. We assessed outcomes and factors associated with stages 2 and 3 AKI in patients with cirrhosis in the North American Consortium for the Study of End-stage Liver Disease cohort. METHODS: We collected data from 2297 hospitalized patients with cirrhosis and ascites from December 2011 through February 2017. Our final analysis included 760 patients who developed AKI per the International Ascites Club 2015 definition (419 with maximum stage 1 and 341 with maximum stage 2 or 3; 63% male; mean age, 58 y). We compared demographic features, laboratory values, AKI treatment response, and survival between patients with maximum stage 1 vs patients with stage 2 or 3 AKI. RESULTS: Patients with stage 2 or 3 AKI had higher Model for End-Stage Liver Disease scores (25.9 ± 7.3) than patients with stage 1 AKI (21.9 ± 7.5) (P < .0001). More patients fulfilled systemic inflammatory response syndrome criteria on admission, and more developed a second nosocomial infection (P < .05 for both comparisons). More patients with stage 2 or 3 AKI also had progression of AKI and required dialysis and admission into intensive care units when compared to stage 1 AKI patients (P < .0001 for both). A lower proportion of patients with stage 2 or 3 AKI survived their hospital stay (80% vs 99% with stage 1 AKI; P < .0001), or survived for 30 days without a liver transplant (56% vs 81%; P < .0001). The development of stage 2 or 3 AKI was associated with a higher Model for End-Stage Liver Disease score at the time of admission (P < .0001), presence of systemic inflammatory response on admission (P = .039), and second infection (P < .0001). CONCLUSIONS: Based on an analysis of data from the North American Consortium for the Study of End-stage Liver Disease cohort, we found that patients with cirrhosis and more advanced liver disease, as well as a second infection, are more likely to develop stages 2 or 3 AKI, with a progressive course associated with decreased 30-day transplant-free survival. Prevention of AKI progression in patients with cirrhosis and stage 2 or 3 AKI might improve their outcomes.

RESUMEN

INTRODUCTION: Readmission and death in cirrhosis are common, expensive, and difficult to predict. Our aim was to evaluate the abilities of multiple artificial intelligence (AI) techniques to predict clinical outcomes based on variables collected at admission, during hospitalization, and at discharge. METHODS: We used the multicenter North American Consortium for the Study of End-Stage Liver Disease (NACSELD) cohort of cirrhotic inpatients who are followed up through 90-days postdischarge for readmission and death. We used statistical methods to select variables that are significant for readmission and death and trained 3 AI models, including logistic regression (LR), kernel support vector machine (SVM), and random forest classifiers (RFC), to predict readmission and death. We used the area under the receiver operating characteristic curve (AUC) from 10-fold crossvalidation for evaluation to compare sexes. Data were compared with model for end-stage liver disease (MELD) at discharge. RESULTS: We included 2,170 patients (57 ± 11 years, MELD 18 ± 7, 61% men, 79% White, and 8% Hispanic). The 30-day and 90-day readmission rates were 28% and 47%, respectively, and 13% died at 90 days. Prediction for 30-day readmission resulted in 0.60 AUC for all patients with RFC, 0.57 AUC with LR for women-only subpopulation, and 0.61 AUC with LR for men-only subpopulation. For 90-day readmission, the highest AUC was achieved with kernel SVM and RFC (AUC = 0.62). We observed higher predictive value when training models with only women (AUC = 0.68 LR) vs men (AUC = 0.62 kernel SVM). Prediction for death resulted in 0.67 AUC for all patients, 0.72 for women-only subpopulation, and 0.69 for men-only subpopulation, all with LR. MELD-Na model AUC was similar to those from the AI models. DISCUSSION: Despite using multiple AI techniques, it is difficult to predict 30- and 90-day readmissions and death in cirrhosis. AI model accuracies were equivalent to models generated using only MELD-Na scores. Additional biomarkers are needed to improve our predictive capability (See also the visual abstract at http://links.lww.com/AJG/B710).

RESUMEN

RATIONALE & OBJECTIVE: Transplant centers in the United States are increasingly willing to transplant kidneys from hepatitis C virus (HCV)-infected (HCV+) donors into HCV- recipients. We studied the association between donor HCV infection status and kidney allograft function and posttransplantation allograft biopsy findings. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: We examined 65 HCV- recipients who received a kidney from a HCV+ donor and 59 HCV- recipients who received a kidney from a HCV- donor during 2018 at a single transplant center. EXPOSURE: Predictor(s) of donor infection with HCV. OUTCOMES: Kidney allograft function and allograft biopsy findings during the first year following transplantation. ANALYTICAL APPROACH: We compared estimated glomerular filtration rate (eGFR), findings on for-cause and surveillance protocol biopsies, development of de novo donor-specific antibodies (DSAs), and patient and allograft outcomes during the first year following transplantation between recipients of HCV+ and HCV- kidneys. We used linear regression to estimate the independent association between allograft function and HCV viremic status of the kidney donor. RESULTS: The mean age of recipients was 52 ± 11 (SD) years, 43% were female, 19% and 80% of recipients were White and Black, respectively. Baseline characteristics were similar between the HCV+ and HCV- groups. There were no statistically significant differences between the HCV+ and HCV- groups in delayed graft function rates (12% vs 8%, respectively); eGFRs at 3, 6, 9, and 12 months post-transplantation; proportions of patients with cellular rejection (6% vs 7%, respectively); and proportions with antibody-mediated rejection (7% vs 10%, respectively) or de novo DSAs (31% vs 20%, respectively). HCV viremic status was not associated with eGFR at 3, 6, 9, or 12 months. LIMITATIONS: Generalizability from a single-center study and small sample size was limited. CONCLUSIONS: Recipients of kidneys from donors infected with HCV had similar kidney allograft function and probability of rejection in the first year after transplantation compared to those who received kidneys from donors without HCV infection.

RESUMEN

BACKGROUND: The virologic and histologic outcomes of a hepatitis C virus (HCV)-infected liver graft into an HCV-negative recipient are not well understood. We aimed to evaluate the sustained virologic response (SVR) rate and the liver histology at 1 year post-Orthotopic liver transplantation (OLT) with an HCV-infected graft. METHODS: A total of 33 patients received the HCV antibody (Ab)+/nucleic acid amplification test (NAT)+ graft. Of these patients, 23 were HCV-negative recipients and 10 were HCV-positive recipients. The 1-year biopsy data were available for 24 patients: 15 patients in HCV-negative group who received an HCV Ab+/NAT+graft and 9 patients in HCV-positive group who received an HCV Ab+/NAT+ graft. Patients with (+) HCV ribonucleic acid (RNA) were started on direct-acting antiviral (DAA) treatment approximately 107 days after OLT using either a Glecaprevir-Pibrentasvir or Sofosbuvir-Velpatasvir or Sofosbuvir-Ledipasvir. RESULTS: All patients (n = 33) were treated with DAA and achieved SVR. The 1-year post-OLT liver biopsies were available in 24 patients: 9 patients had F1 and F2 fibrosis and 17 patients had minimal to moderate inflammation. There was no statistical difference in fibrosis and inflammation between the HCV-negative vs. HCV-positive recipients. All patients who received the NAT+ graft developed viremia and subsequently achieved SVR with treatment. CONCLUSION: At 1 year protocol liver biopsy, patients had inflammation consistent with viral hepatitis despite the successful eradication of HCV.

RESUMEN

The opioid epidemic has led to increased availability of organs for liver transplantation. The success of direct-acting antiviral therapy for hepatitis C (HCV) has led to the acceptance of HCV viremic donor organs. Nucleic acid testing (NAT) has led to increased detection of HCV and hepatitis B (HBV) in potential donors. A total of 36 patients underwent liver transplantation from donation after brain death donors who were HCV NAT-positive, and three of them were diagnosed with HBV several months after. All three recipients received livers from HCV viremic donors who were negative for HBV by serology and NAT. Soon after liver transplantation, HCV was treated, and all achieved sustained virologic response. They became HBV DNA-positive shortly thereafter. To date, there have been no reported cases of unexpected HBV transmission since universal donor NAT was implemented in 2013. We postulate that the inhibitory effect of HCV viremia on HBV may have prolonged the "NAT window period" in these donors beyond the 20-22 days quoted for solitary HBV infection. These cases highlight the need for more intensive and prolonged screening for HBV in recipients of livers from HCV viremic donors.

RESUMEN

BACKGROUND: Hepatic hydrothorax (HH) remains a difficult-to-treat complication of cirrhosis. AIM: To define the mortality, length of stay (LOS), and risk of ACLF in patients admitted with HH. METHODS: We utilized the North American Consortium for the Study of End-stage Liver Disease, a prospective cohort of 2868 non-electively hospitalized patients with cirrhosis from 14 tertiary care hepatology centers in North America. A total of 121 patients who required an inpatient thoracentesis (HH group) were compared to 736 patients with refractory ascites without HH, and to 1639 patients without these complications (Other). Patients with a TIPS before or during admission were excluded. RESULTS: There were no differences between the groups in age, gender, or liver disease etiology. Admission MELD (20.5, 21.6 vs. 18.7; p < 0.0001) was lower in HH than RA patients but lowest in other patients, respectively. In hospital, HH patients' rate of second infections and ICU transfer were the highest, and their LOS was the longest of all groups. Despite a similar mean discharge MELD compared to RA patients, the 90-day transplant rate was lower. Multivariable modeling showed patients with HH had an increased risk of ACLF (HR = 2.37 vs. RA, HR = 2.56 vs. Other; p = 0.01) even when controlling for MELD score, AKI, second infection, and history of prior 6-month hospitalization. Multivariable modeling also showed that HH increased the risk of inpatient mortality (HR = 2.22 vs. RA alone, HR = 2.31 vs. Other; p = 0.04). CONCLUSIONS: HH that required a therapeutic thoracentesis more than doubled the risk of ACLF and inpatient mortality among hospitalized patients with cirrhosis.

RESUMEN

Morbid obesity is considered a relative contraindication for liver transplantation (LT). We investigated if body mass index (BMI; lean versus obese) is a risk factor for post-LT graft and overall survival in nonalcoholic steatohepatitis (NASH) and non-NASH patients. Using the United Network for Organ Sharing (UNOS) database, LT recipients from January 2002 to June 2013 (age ≥18 years) with follow-up until 2017 were included. The association of BMI categories calculated at LT with graft and overall survival after LT were examined. After adjusting for confounders, all obesity cohorts (overweight and class 1, class 2, and class 3 obesity) among LT recipients for NASH had significantly reduced risk of graft and patient loss at 10 years of follow-up compared with the lean BMI cohort. In contrast, the non-NASH group of LT recipients had no increased risk for graft and patient loss for overweight, class 1, and class 2 obesity groups but had significantly increased risk for graft (P < 0.001) and patient loss (P = 0.005) in the class 3 obesity group. In this retrospective analysis of the UNOS database, adult recipients selected for first LT and NASH patients with the lowest BMI have the worse longterm graft and patient survival as opposed to non-NASH patients where the survival was worse with higher BMI.

RESUMEN

BACKGROUND: Opioid medications are frequently used to address pain among patients with cirrhosis, including those on the liver transplant (LT) waitlist and after transplantation. However, opioid use has been associated with poor allograft outcomes and reduced transplant survival. We examined the impact of opioid use across the spectrum of advanced liver disease, from the initial hepatology consultation for cirrhosis through transplant referral, listing, and the post-LT process. METHODS: The study includes all patients referred for cirrhosis management in a single healthcare system in the United States. Data were extracted retrospectively through medical chart review. RESULTS: Of 414 patients included in the study, 104 (25%) were treated with opioid. Patients on opioids were more likely to be White, have body mass indices (BMI) >30, have HCV, suffer from hepatic encephalopathy, cigarette smokers, and use benzodiazepines concurrently. Higher doses of opioids were associated with multiple emergency department (ED). Eighty-nine underwent LT, including 20 opioid-treated patients. There was no difference found between the opioid and non-opioid groups with regard to allograft loss, ED visits, and hospital readmissions at 2 years post-LT follow-up. CONCLUSIONS: Opioid treatment was common among patients with cirrhosis. We did not find increased negative outcomes among opioid users across the spectrum of cirrhosis. However, the sample for LT patients was small.

RESUMEN

There is a dearth of published data regarding the presence of post-transplant donor-specific antibodies (DSA), especially C1q-binding DSA (C1q+DSA), and patient and kidney allograft outcomes in simultaneous liver-kidney transplant (SLKT) recipients. We conducted a retrospective cohort study consisted of 85 consecutive SLKT patients between 2009 and 2018 in our center. Associations between presence of post-transplant DSA, including persistent and/or newly developed DSA and C1q+DSA, and all-cause mortality and the composite outcome of mortality, allograft kidney loss, and antibody-mediated rejection were examined using unadjusted and age and sex-adjusted Cox proportional hazards and time-dependent regression models. The mean age at SLKT was 56 years and 60% of the patients were male. Twelve patients (14%) had post-transplant DSA and seven patients (8%) had C1q+DSA. The presence of post-transplant DSA was significantly associated with increased risk of mortality (unadjusted model: Hazard Ratio (HR) = 2.72, 95% confidence interval (CI): 1.06-6.98 and adjusted model: HR = 3.20, 95% CI: 1.11-9.22) and the composite outcome (unadjusted model: HR = 3.18, 95% CI: 1.31-7.68 and adjusted model: HR = 3.93, 95% CI: 1.39-11.10). There was also higher risk for outcomes in recipients with C1q+DSA compared the ones without C1q+DSA. Post-transplant DSA is significantly associated with worse patient and kidney allograft outcomes in SLKT. Further prospective and large cohort studies are warranted to better assess these associations.

RESUMEN

BACKGROUND: Little is known about patients discharged to hospice following hospitalization for complications of cirrhosis. AIM: We sought to understand the current pattern of hospice utilization in patients with cirrhosis by evaluating the North American Consortium for the Study of End-stage Liver Disease (NACSELD) cohort. METHODS: Patients with cirrhosis from 14 tertiary-care hepatology centers across North America non-electively hospitalized and prospectively enrolled were evaluated. Exclusion criteria included HIV infection, transplantation or non-hepatic malignancy. Random computer-based propensity score matching was undertaken in a 1:2 ratio based on admission MELD score ± 3 points. RESULTS: Totally, 2718 patients were enrolled, 5% (N = 132) were discharged to hospice, 6% (N = 171) died, and the rest were discharged alive. Patients discharged to hospice were older (60 vs. 57 years, p = 0.04), less likely to have had SBP (13% vs. 28%, p = 0.002) and be listed for liver transplantation (11% vs. 26%, p = 0.0007). Features, on multivariable modeling, associated with increased probability of discharge to hospice as opposed to being discharged alive: grade-3-4 hepatic encephalopathy, a higher Child-Turcotte-Pugh (CTP) score, and a higher discharge serum creatinine; however, a higher serum sodium, being listed for transplant and being prescribed rifaximin or a statin were protective from hospice discharge. CONCLUSION: Patients with more advanced liver disease, hepatic encephalopathy, renal dysfunction, and those not candidates for liver transplantation were more likely to be discharged to hospice. However, in this sick multinational cohort of cirrhotic inpatients, it seems that hospice is markedly underutilized (5%) since 25% of patients not discharged to hospice died within 6 months.

RESUMEN

BACKGROUND: We aimed to assess the probability and factors associated with the presence of hepatitis C virus (HCV) antibody among HCV seronegative kidney transplant recipients receiving HCV-infected (nucleic acid testing positive) donor kidneys. METHODS: This is a retrospective review examining HCV antibody seroconversion of all kidney transplant recipients receiving an organ from an HCV-infected donor between 1 March 2018 and 2 December 2019 at a high-volume kidney transplant center in the southeast United States. RESULTS: Of 97 patients receiving HCV-infected kidneys, the final cohort consisted of 85 recipients with 5 (5.9%) recipients noted to have HCV antibody seroconversion in the setting of HCV viremia. The HCV RNA level at closest time of antibody measurement was higher in the seroconverted patients versus the ones who never converted [median and (interquartile range): 1,091,500 (345,000-8,360,000) vs 71,500 (73-313,000), p = 0.02]. No other significant differences including type of immunosuppression were noted between the HCV antibody positive group and HCV antibody negative group. Donor donation after cardiac death status [Odds Ratio (OR) and 95% Confidence Interval (CI) was: 8.22 (1.14-59.14)], donor age [OR (95% CI) (+5 years) was: 3.19 (1.39-7.29)] and Kidney Donor Profile Index [OR (95% CI) (+1) was:1.07 (1.01-1.15)] showed a statistically significant association with HCV seroconversion. CONCLUSIONS: HCV antibody should not be considered routine screening for presence of infection in previously HCV naïve kidney transplant recipients receiving kidneys from HCV-infected donors, as only a modest percentage have antibody despite active viremia. The assessment of HCV viral load should be routine in all transplant recipients receiving organs from public health service increased risk donors.

RESUMEN

Our aim was to evaluate the safety of transplanting kidneys from HCV-infected donors in HCV-uninfected recipients. Data collected from 53 recipients in a single center, observational study included donor and recipient characteristics, liver and kidney graft function, new infections and de novo donor-specific antibodies and renal histology. Treatment with a direct-acting antiviral regimen was initiated when HCV RNA was detected. The mean ± SD age of recipients was 53 ± 11 years, 34% were female, 19% and 79% of recipients were white and African American, respectively. The median and interquartile range (IQR) time between transplant and treatment initiation was 76 (IQR: 68-88) days. All 53 recipients became viremic (genotype: 1a [N = 34], 1b [N = 1], 2 [N = 3], and 3 [N = 15]). The majority (81%) of recipients did not experience clinically significant increases (>3 times higher than upper limit of the normal value) in aminotransferase levels and their HCV RNA levels were in the 5 to 6 log range. One patient developed fibrosing cholestatic hepatitis with complete resolution. All recipients completed antiviral treatment and 100% were HCV RNA-negative and achieved 12-week sustained virologic response. The estimated GFRs at end of treatment and 12-week posttreatment were 67 ± 21 mL/min/1.73 m2 and 67 ± 17 mL/min/1.73 m2 , respectively. Four recipients developed acute rejection. Kidney transplantation from HCV-infected donors to HCV-negative recipients should be considered in all eligible patients.

RESUMEN

OBJECTIVES: Antibiotic prophylaxis is recommended for prevention of the first episode of spontaneous bacterial peritonitis (SBP; primary prophylaxis 1°) and subsequent episodes (secondary prophylaxis 2°). We aimed to compare outcomes in cirrhotic inpatients on 1° vs 2° SBP prophylaxis. METHODS: Data from North American Consortium for the Study of End-Stage Liver Disease were evaluated for cirrhosis details, reasons for admission/medications, inpatient course recorded, and outcomes over 90 days. Outcomes (intensive care units, acute kidney injury, inpatient/90-day mortality) were compared between the 2 groups after propensity-matching on admission model for end-stage liver disease (MELD) score and serum albumin. RESULTS: Among the 2,731 patients enrolled, 305 were on 1° and 187 on 2° SBP prophylaxis. After propensity-matching, 154 patients remained in each group. Patients on 1° prophylaxis were more likely to have admission systemic inflammatory response syndrome (P = 0.02), with higher intensive care unit admissions (31% vs 21%; P = 0.05) and inpatient mortality (19% vs 9%; P = 0.01) than the 2° prophylaxis group. Patients on 2° prophylaxis had higher total (22% vs 10%; P = 0004), readmission (16% vs 9%; P = 0.03), and nosocomial (6% vs 0.5%; P = 0.01) SBP rates with predominant Gram-negative organisms compared to 1° prophylaxis patients. At 90 days, 1° prophylaxis patients had a higher mortality (35% vs 22%; P = 0.02) and acute kidney injury incidence (48% vs 30%; P = 0.04) compared to 2° prophylaxis patients. DISCUSSION: In this inpatient cirrhosis study, despite prophylaxis, a high proportion of patients developed SBP, which was associated with mortality. Cirrhotic inpatients on 1° prophylaxis had worse outcomes than those on 2° prophylaxis when propensity-matched for the MELD score and serum albumin during the index admission and 90-day follow-up.

RESUMEN

OBJECTIVES: Nosocomial infections (NIs) can be a major cause of morbidity and mortality in cirrhosis. This study aims to define the determinants of NI development and its impact on 30-day outcomes among hospitalized patients with cirrhosis. METHODS: North American Consortium for the Study of End-Stage Liver Disease enrolled patients with cirrhosis who were admitted nonelectively. Admission variables and 30-day outcomes were compared between patients with and without NI. These were also compared based on whether there was an isolated admission infection, NI, or both. Models were created for NI development using admission variables and for 30-day mortality. RESULTS: The study included 2,864 patients; of which, 15% (n = 436) developed NI. When comparing NI vs no NI, 1,866 patients were found to be infection free, whereas 562 had admission infections only, 228 had only NI, and 208 had both infections. At admission, patients with NI were more likely to be infected and have advanced cirrhosis. NIs were associated with higher rates of acute-on-chronic liver failure, death, and transplant regardless of admission infections. Patients with NI had higher respiratory infection, urinary tract infection, Clostridium difficile infection, fungal infections, and infection with vancomycin-resistant enterococci compared with patients without NI. Risk factors for NIs were admission infections, model for end-stage liver disease (MELD) > 20, systemic inflammatory response syndrome criteria, proton pump inhibitor, rifaximin, and lactulose use, but the regression model (sensitivity, 0.67; specificity, 0.63) was not robust. Age, alcohol etiology, admission MELD score, lactulose use, acute-on-chronic liver failure, acute kidney injury, intensive care unit, and NI increased the risk of death, whereas rifaximin decreased the risk of death. DISCUSSION: NIs are prevalent in hospitalized patients with cirrhosis and are associated with poor outcomes. Although higher MELD scores and systemic inflammatory response syndrome are associated with NI, all hospitalized patients with cirrhosis require vigilance and preventive strategies.

RESUMEN

Acute-on-chronic liver failure (ACLF) characterized with ≥2 extrahepatic organ failures in cirrhosis carries a high mortality. Outcomes of patients listed for liver transplantation (LT) after ACLF and after LT are largely unknown. The North American Consortium for the Study of End-Stage Liver Disease prospectively enrolled 2793 nonelectively hospitalized patients with cirrhosis; 768 were listed for LT. Within 3 months, 265 (35%) received a LT, 395 remained alive without LT, and 108 died/delisted. Compared with nonlisted patients, those listed were younger and more often had ACLF, acute kidney injury, and a higher admission Model for End-Stage Liver Disease (MELD) score. ACLF was most common in patients who died/delisted, followed by those alive with and without LT respectively, (30%, 22%, and 7%, respectively; P < 0.001). At LT, median MELD was 27.9% and 70% were inpatients; median time from hospitalization to LT was 26 days. Post-LT survival at 6 months was unchanged between those with and without ACLF (93% each at 6 months). There was no difference in 3- and 6-month mean post-LT creatinine in those with and without ACLF, despite those with ACLF having a higher mean pre-LT creatinine and a higher rate of perioperative dialysis (61%). In conclusion, patients with and without ACLF had similar survival after transplant with excellent renal recovery in both groups.

RESUMEN

We hypothesize that the prevalence of chronic kidney disease (CKD) among patients with cirrhosis has increased due to the increased prevalence of CKD-associated comorbidities, such as diabetes. We aimed to assess the characteristics of hospitalized patients with cirrhosis with CKD and its impact on renal and patient outcomes. The North American Consortium for the Study of End-Stage Liver Disease (NACSELD) prospectively enrolled nonelectively admitted patients with cirrhosis and collected data on demographics, laboratory results, in-hospital clinical course, and postdischarge 3-month outcomes. CKD positive (CKD+) patients, defined as having an estimated glomerular filtration rate (eGFR; Modification of Diet in Renal Disease-4 variable formula) of ≤60 mL/minute for >3 months, were compared with chronic kidney disease negative (CKD-) patients for development of organ failures, hospital course, and survival. There were 1099 CKD+ patients (46.8% of 2346 enrolled patients) who had significantly higher serum creatinine (2.21 ± 1.33 versus 0.83 ± 0.21 mg/dL in the CKD- group) on admission, higher prevalence of nonalcoholic steatohepatitis cirrhosis etiology, diabetes, refractory ascites, and hospital admissions in the previous 6 months compared with the CKD- group (all P < 0.001). Propensity matching (n = 922 in each group) by Child-Pugh scores (9.78 ± 2.05 versus 9.74 ± 2.04, P = 0.70) showed that CKD+ patients had significantly higher rates of superimposed acute kidney injury (AKI; 68% versus 21%; P < 0.001) and eventual need for dialysis (11% versus 2%; P < 0.001) than CKD- patients. CKD+ patients also had more cases of acute-on-chronic liver failure as defined by the NACSELD group, which was associated with reduced 30- and 90-day overall survival (P < 0.001 for both). A 10 mL/minute drop in eGFR was associated with a 13.1% increase in the risk of 30-day mortality. In conclusion, patients with CKD should be treated as a high-risk group among hospitalized patients with cirrhosis due to their poor survival, and they should be monitored carefully for the development of superimposed AKI.

RESUMEN

This study assessed the efficacy and safety of ribavirin-free coformulated glecaprevir/pibrentasvir (G/P) in patients with hepatitis C virus genotype 3 infection with prior treatment experience and/or compensated cirrhosis, a patient population with limited treatment options. SURVEYOR-II, Part 3 was a partially randomized, open-label, multicenter, phase 3 study. Treatment-experienced (prior interferon or pegylated interferon ± ribavirin or sofosbuvir plus ribavirin ± pegylated interferon therapy) patients without cirrhosis were randomized 1:1 to receive 12 or 16 weeks of G/P (300 mg/120 mg) once daily. Treatment-naive or treatment-experienced patients with compensated cirrhosis were treated with G/P for 12 or 16 weeks, respectively. The primary efficacy endpoint was the percentage of patients with sustained virologic response at posttreatment week 12 (SVR12). Safety was evaluated throughout the study. There were 131 patients enrolled and treated. Among treatment-experienced patients without cirrhosis, SVR12 was achieved by 91% (20/22; 95% confidence interval [CI], 72-97) and 95% (21/22; 95% CI, 78-99) of patients treated with G/P for 12 or 16 weeks, respectively. Among those with cirrhosis, SVR12 was achieved by 98% (39/40; 95% CI, 87-99) of treatment-naive patients treated for 12 weeks and 96% (45/47; 95% CI, 86-99) of patients with prior treatment experience treated for 16 weeks. No adverse events led to discontinuation of study drug, and no serious adverse events were related to study drug. Conclusion: Patients with hepatitis C virus genotype 3 infection with prior treatment experience and/or compensated cirrhosis achieved high SVR12 rates following 12 or 16 weeks of treatment with G/P. The regimen was well tolerated. (Hepatology 2018;67:514-523).
