Beyond the Checkpoint: Severe Axitinib-induced Liver Injury.

Understanding the potential adverse effects associated with oncological treatments is crucial in the clinical care of patients with cancer. We describe the first case report delineating severe acute liver injury secondary to axitinib. This is a case of metastatic renal cell carcinoma treated with axitinib and pembrolizumab, complicated by a severe axitinib-induced liver injury, characterized by significant elevations of hepatocellular and cholestatic liver enzymes during initial treatment and rechallenge of axitinib. Remarkably, the liver chemistries normalized upon discontinuation of the medication.

Prognostic Models in Acute-on-Chronic Liver Failure.

Acute-on-chronic liver failure (ACLF) is a clinical syndrome characterized by severe hepatic dysfunction leading to multiorgan failure in patients with end-stage liver disease. ACLF is a challenging clinical syndrome with a rapid clinical course and high short-term mortality. There is no single uniform definition of ACLF or consensus in predicting ACLF-related outcomes, which makes comparing studies difficult and standardizing management protocols challenging. This review aims to provide insights into the common prognostic models that define and grade ACLF.

Type 2 diabetes complications are associated with liver fibrosis independent of hemoglobin A1c.

INTRODUCTION AND OBJECTIVES: The association between type 2 diabetes, non-alcoholic fatty liver disease, and liver fibrosis is well established, but it is unknown whether complications of type 2 diabetes influence fibrosis levels. We defined the complications of type 2 diabetes by the presence of diabetic nephropathy, retinopathy, or neuropathy and aimed to evaluate their association with the degree of liver fibrosis measured by the fibrosis-4 (FIB-4) index. MATERIALS AND METHODS: This is a cross-sectional study evaluating the association of type 2 diabetes complications with liver fibrosis. A total of 2389 participants were evaluated from a primary care practice. FIB-4 was evaluated as a continuous and categorical measure using linear and ordinal logistic regression. RESULTS: Patients with complications were older, had higher hemoglobin A1c, and a higher median FIB-4 score (1.34 vs. 1.12, P<0.001). On adjusted analysis, type 2 diabetes complications were associated with higher fibrosis by continuous FIB-4 score (Beta-coefficient: 0.23, 95% confidence interval [CI]: 0.004-1.65) and demonstrated increased odds of fibrosis by categorical FIB-4 score (odds ratio [OR]: 4.48, 95% CI: 1.7-11.8, P=0.003), independent of hemoglobin A1c level. CONCLUSIONS: The presence of type 2 diabetes complications is associated with the degree of liver fibrosis, independent of hemoglobin A1c level.

Pharmacological Therapy of Pruritus in Primary Biliary Cholangitis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

GOALS: We aim to summarize the current management of pruritus in primary biliary cholangitis (PBC) by evaluating the efficacy and safety of pharmacological therapies. BACKGROUND: Pruritus is a common symptom of PBC, and evidence regarding the most effective antipruritic agents available is lacking. New pharmacotherapy for PBC has shown promising antipruritic effects. STUDY: We performed a systematic literature review and meta-analysis including all available double-blind, randomized, placebo-controlled clinical trials that evaluated the efficacy of pharmacotherapy for the symptomatic management of pruritus in PBC. Pruritus was assessed as either a change from baseline or a postintervention score. RESULTS: We included 33 studies and 20 medications. Using the visual analog scale, cholestyramine did not significantly improve pruritus compared with placebo [standardized mean differences (SMD): -0.94, 95% CI: -2.05 to 0.17], whereas rifampin and nalfurafine hydrochloride both significantly improved pruritus (SMD: -3.29, 95% CI: -5.78 to -0.80; n=23 and SMD: -0.58, 95% CI: -1.04 to -0.12). In addition, Bezafibrate and linerixibat significantly improved pruritus (SMD: -1.05, 95% CI: -1.41 to -0.68; n=110 and SMD: -0.31, 95% CI: -0.62 to -0.04, respectively). This effect was also present within the subgroup analysis by pruritus scale, where both bezafibrate and linerixibat significantly improved pruritus compared with placebo (SMD: -1.09, 95% CI: -1.54 to -0.65; P <0.001; visual analog scale; as postintervention score and SMD: -0.31, 95% CI: -0.62 to -0.01; P =0.04; numeric rating scale; as a change from baseline score, respectively). CONCLUSIONS: Bezafibrate and Linerixibat are potential second-line antipruritic medications for PBC, particularly those with moderate to severe pruritus.

Waitlist and posttransplantation outcomes of lean individuals with nonalcoholic fatty liver disease.

Lean individuals with nonalcoholic fatty liver disease (NAFLD) represent a subset of patients with a distinct risk factor profile. We assessed the association between body mass index (BMI) on waitlist and postliver transplantation (LT) outcomes among these patients. We retrospectively analyzed the United Network for Organ Sharing data, including adult patients with NAFLD listed for LT between February 27, 2002, and June 30, 2020. We first used competing risk analyses to estimate the association of BMI with waitlist removal due to death or clinical deterioration. We then conducted Kaplan-Meier estimates and Cox regression models to determine the impact of weight change during the waiting list on all-cause mortality and graft failure after LT. Patients with normal weight (BMI 18.5-24.9 kg/m 2 ) suffered higher waitlist removal (adjusted subdistribution hazard ratio 1.26, 95% confidence interval [CI] 1.10-1.43; p = 0.001) compared with patients with obesity class I (BMI 30-34.9 kg/m 2 ). Those who remained at normal weight had higher all-cause mortality (adjusted hazard ratio [aHR] 1.61, 95% CI 1.32-1.96; p <0.001) and graft failure (aHR 1.57, 95% CI 1.32-1.88; p <0.001) than patients with stable obesity. Among patients with normal weight, those with the greatest weight increase (BMI gain ≥3 kg/m 2 ) had lower all-cause mortality (aHR 0.55, 95% CI 0.33-0.93; p = 0.03) and graft failure (aHR 0.49, 95% CI 0.30-0.81; p = 0.01) compared with patients with stable weight (BMI change ≤1 kg/m 2 ). Patients with NAFLD with normal weight have increased waitlist removal and those who remained at normal weight during the waitlist period have worse posttransplantation outcomes. Identifying and addressing factors influencing apparent healthy weight prior to LT are crucial to mitigate poor outcomes.

Steroid Use and Risk of Nonalcoholic Fatty Liver Disease in Patients With Inflammatory Bowel Disease: Systematic Review and Meta-analysis.

GOALS: We sought to evaluate the association of steroids with nonalcoholic fatty liver disease (NAFLD) among patients with inflammatory bowel disease (IBD). BACKGROUND: Patients with IBD are at increased risk of NAFLD. Steroids may have a role in the pathogenesis of NAFLD. STUDY: We searched MEDLINE (through PubMed) and Embase for studies from inception to July 2021. We included published interventional and observational studies of adults 18 years or older with ulcerative colitis or Crohn's disease. We reported odds ratios, 95% confidence intervals, and generated forest plots. A random effects model generated a summary effect estimate. Publication bias was assessed by funnel plot and Egger's test. Study quality was examined using modified Newcastle-Ottawa scale (NOS) and Agency for Healthcare Research and Quality (AHRQ). RESULTS: A total of 12 observational studies with 3497 participants were included. NAFLD was identified in 1017 (29.1%) patients. The pooled odds ratio for the development of NAFLD in steroid users versus non-users was 0.87 (95% confidence interval: 0.72-1.04). There was no significant heterogeneity between studies ( I ²=0.00%, P =0.13). No publication bias was detected by funnel plot or Egger's test ( P =0.24). Findings were consistent among subgroup analyses stratified by study quality. CONCLUSION: In this meta-analysis, steroids were not associated with NAFLD in patients with IBD. Steroids may not need to be withheld from patients with IBD for the purposes of preventing NAFLD. Additional prospective studies that systematically document steroid exposure and important confounders among patients with IBD are warranted.

Severe Hepatic Steatosis by Controlled Attenuation Parameter Predicts Quality of Life Independent of Fibrosis.

BACKGROUND & AIM: Liver fibrosis is associated with poor patient-reported outcomes (PROs), but the impact of steatosis is unknown. We aimed to evaluate the impact of steatosis on PROs independent of liver fibrosis. METHODS: We evaluated the impact of steatosis, measured by Controlled-Attenuation Parameter (CAP) on transient elastography, and PROs using the 2017-2018 National Health and Nutrition Examination Survey (NHANES) database. We used univariate and multivariate logistic and ordinal regression to evaluate categorical CAP score with PROs measuring physical disability, general health and depression. RESULTS: Of 4,509 participants included, 38% had severe steatosis (> 280 dB/m). Those with severe steatosis were older and more likely to be male (56% vs. 43% and 51%). On univariate analysis, severe steatosis was associated with more difficulty walking (P = 0.01), dressing (P = 0.005), lifting objects (P = 0.02), bending (P < 0.001), and moving large objects (P = 0.0006). After multivariate adjustment, severe steatosis remained associated with difficulty lifting objects (odds ratio [OR]: 1.7, 95% confidence interval [CI]: 1.2-2.4, P = 0.01) and difficulty bending (OR: 1.8, 95% CI: 1.2-2.7, P = 0.006). Severe steatosis increased risk of having any of the disabilities (OR: 1.7, 95% CI: 1.2-2.4, P = 0.008) and had higher ordinal disability index (OR: 1.6, 95% CI: 1.2-2.2, P = 0.007). Lastly, severe steatosis was also associated with worse self-perceived health status (OR: 1.5, 95% CI: 1.2-1.9, P = 0.002), while general health compared to one year ago and depression trended toward significance. CONCLUSION: Patients with severe steatosis are at increased risk of physical disability and have worse self-perceived health status independent of liver fibrosis.

Pregnancy in Chronic Liver Disease: Before and After Transplantation.

Chronic liver disease poses various challenges for women of reproductive age. Cirrhosis, particularly if decompensated, and liver transplantation may impact gestation and perinatal outcomes. Tailored management of underlying liver disease is critical to optimize maternal and fetal wellbeing. Early education, timely intervention, close monitoring, and a multidisciplinary approach are key elements required to minimize complications and increase chances of a safe and successful pregnancy. In this review, we focus on the pregnancy-related implications of chronic liver disease and liver transplantation on women of reproductive age and highlight disease-specific management considerations.

Waitlist Mortality and Posttransplant Outcomes in African Americans with Autoimmune Liver Diseases.

BACKGROUND: Liver transplantation is indicated in end-stage liver disease due to autoimmune diseases. The liver allocation system can be affected by disparities such as decreased liver transplant referrals for racial minorities, especially African Americans that negatively impact the pre- and posttransplant outcomes. AIM: To determine differences in waitlist survival and posttransplant graft survival rates between African American and Caucasian patients with autoimmune liver diseases. Study. The United Network for Organ Sharing database was used to identify all patients with autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis who underwent liver transplant from 1988 to 2019. We compared waitlist survival and posttransplant graft survival between Caucasians and African Americans using Kaplan-Meier curves and Cox regression models. We also evaluated the cumulative incidence of death or delisting for deterioration and posttransplant incidence of death and retransplantation using competing risk analysis. RESULTS: African Americans were more likely to be removed from the waitlist for death or clinical deterioration (subdistribution hazard ratio (SHR) 1.26, 95% CI 1-1.58, P=0.046) using competing risk analysis. On multivariate Cox regression analysis, there was no difference in posttransplant graft survival among the two groups (hazard ratio (HR) 1.10, 95% CI 0.98-1.23, P=0.081). CONCLUSIONS: Despite the current efforts to reduce racial disparities, we found that African Americans are more likely to die on the waitlist for liver transplant and are less likely to be transplanted, with no differences in graft survival rates. The persistence of healthcare disparities continues to negatively impact African Americans.

Comparison of transient elastography and Model for End-Stage Liver Disease-sodium to Model for End-Stage Liver Disease-sodium alone to predict mortality and liver transplantation.

OBJECTIVES: Model for End-Stage Liver Disease (MELD) alone and with sodium (MELD-Na) have decreasing predictive capacity as trends in liver disease evolve. We sought to combine transient elastography (TE) with MELD-Na to improve its predictive ability. METHODS: This is a retrospective cohort study comparing the use of TE, MELD-Na, and composite MELD-Na-TE to predict liver transplantation and all-cause mortality, with hepatic decompensation as a secondary outcome. Cox proportional hazards regression was used to measure predictive ability and control for confounders. RESULTS: Of the 214 patients, the mean age was 53 years with 35% being female and 76% being Caucasian. Hepatitis C (59%) and nonalcoholic fatty liver disease (22%) were the most frequent liver disease etiologies. On univariable analysis, MELD-Na [hazard ratio (HR) 1.12, 95% confidence interval (CI) 1.06-1.2, P < 0.001], TE (HR 1.04, 95% CI 1.03-1.06, P < 0.001) and composite MELD-Na-TE (HR 1.13, 95% CI 1.08-1.19, P < 0.001) were associated with death or transplant. On multivariable analysis, MELD-Na was no longer significant (HR 1.08, 95% CI 0.95-1.22, P = 0.27) after adjusting for TE (HR 1.05, 95% CI 1.03-1.07, P < 0.001) while composite MELD-Na-TE remained significant (HR 1.16, 95% CI 1.09-1.24, P < 0.001). Composite MELD-Na-TE predicts mortality or liver transplant with the highest C-statistic of 0.81. Age (HR 1.05, 95% CI 1-1.09, P = 0.04), TE (HR 1.04, 95% CI 1.03-1.06, P < 0.001) and composite MELD-Na-TE (HR 1.11, 95% CI 1.06-1.15, P < 0.001) were significantly associated with hepatic decompensation. CONCLUSION: Composite MELD-Na-TE better predicts liver transplantation, death, and hepatic decompensation compared to MELD/MELD-Na or TE alone.

Radiographic Hepatic Steatosis Is Not Associated With Key Clinical Outcomes Among Patients Hospitalized With COVID-19.

BACKGROUND: Metabolic syndrome increases adverse outcomes in coronavirus disease 2019 (COVID-19) infection. Hepatic steatosis may increase risk of COVID-19 severity. Current studies evaluating steatosis lack reliable definitions. We aimed to evaluate the association of radiographic hepatic steatosis and clinical outcomes of COVID-19 severity in a diverse cohort. METHODS: We retrospectively identified patients with COVID-19 infection admitted to two US academic hospitals. Outcomes were length of stay, intensive care unit use, mechanical ventilation, and in-hospital mortality. We used Mann-Whitney U-test for continuous measures and Chi-square or Fisher's exact test for categorical measures. Multivariable linear and logistic regression analyses were used to adjust for confounders. RESULTS: Of the 319 patients, 14% had hepatic steatosis. There were no differences in length of stay (6 (4 - 16) vs. 9 (4 - 18) days, P = 0.6), intensive care unit (24% vs. 32%, P = 0.3), mechanical ventilation (28% vs. 38%, P = 0.32), or in-hospital mortality (7% vs. 17%, P = 0.12). After adjustment, there was no difference in length of stay (ß: -14.37, 95% confidence interval (CI): -30.5 - 1.77, P = 0.08), intensive care unit (odds ratio (OR): 0.31, 95% CI: 0.03 - 1.09, P = 0.06), mechanical ventilation (OR: 0.13, 95% CI: 0.02 - 1.09, P = 0.06), or in-hospital mortality (OR: 0.27, 95% CI: 0.06 - 1.16, P = 0.08) among patients with hepatic steatosis. CONCLUSION: Radiographic hepatic steatosis was not associated with worse outcomes among patients hospitalized with COVID-19.

Associations between alcohol consumption and hepatic steatosis in the USA.

Despite being widely recognized as a common cause of fatty liver, the exact impact of alcohol consumption on hepatic steatosis in the general population is elusive. The recent National Health and Nutrition Examination Survey (NHANES) allowed us to examine this relationship among US adults. Herein, we extracted data on detailed alcohol consumption and controlled attenuation parameter (CAP) by FibroScan from 4509 participants in NHANES 2017-2018. Compared to metabolic risk factors such as diabetes and obesity, the association between alcohol consumption and CAP was less significant. In multivariable analysis, only those drinking 5-7 times per week showed significant increases in CAP scores. Although both frequency and quantity of drinking were positively associated with CAP score, only frequency remained significant after adjustment for quantity and binge drinking. These epidemiological observations suggested that the impact of alcohol on hepatic steatosis was much smaller than metabolic factors and dependent upon the frequency of drinking.

Upper Gastrointestinal Bleeding: A Potential Precursor to Bouveret's Syndrome.

Bouveret's syndrome is a rare complication of cholelithiasis. It is characterized by a gallstone entering the intestine through a cholecystoenteric fistula, impacting the duodenum and causing gastric outlet obstruction. Rarely, it presents with hematemesis and melena. The diagnosis involves computed tomography (CT) and the treatment depends on the patient's stability, the location of the obstruction, stone size, and the fistula. Endoscopy or minimally invasive lithotripsy can be considered initially. If this fails, surgical intervention is recommended. We present a case of upper gastrointestinal bleeding (UGIB) preceding the development of Bouveret's syndrome.
