Item A 68-Year-Old Woman With Unexplained Liver Enzyme Elevation and Active Chronic Hepatitis: Beware of Drug-Induced Autoimmune-Like Hepatitis(Elsevier, 2023-10-04) Dara, Lily; Ghabril, Marwan; Phillips, Elizabeth; Kleiner, David; Chalasani, Naga; Medicine, School of MedicineThis patient’s case history (void of protected health information) was discussed in a multidisciplinary meeting including hepatologists (LD, MG), a pathologist (DK), an immunologist (EP) with NC as moderator. We summarize the case history and discussion in the following article.Item Amoxicillin-Clavulanate-Induced Liver Injury(Springer, 2016-08) deLomos, Andrew S.; Ghabril, Marwan; Rockey, Don C.; Gu, Jiezhun; Barnhart, Huiman X.; Fontana, Robert J.; Kleiner, David E.; Bonkovsky, Herbert L.; Department of Medicine, IU School of MedicineBackground and Aims Amoxicillin–clavulanate (AC) is the most frequent cause of idiosyncratic drug-induced injury (DILI) in the US DILI Network (DILIN) registry. Here, we examined a large cohort of AC-DILI cases and compared features of AC-DILI to those of other drugs. Methods Subjects with suspected DILI were enrolled prospectively, and cases were adjudicated as previously described. Clinical variables and outcomes of patients with AC-DILI were compared to the overall DILIN cohort and to DILI caused by other antimicrobials. Results One hundred and seventeen subjects with AC-DILI were identified from the cohort (n = 1038) representing 11 % of all cases and 24 % of those due to antimicrobial agents (n = 479). Those with AC-DILI were older (60 vs. 48 years, P < 0.001). AC-DILI was more frequent in men than women (62 vs. 39 %) compared to the overall cohort (40 vs. 60 %, P < 0.001). The mean time to symptom onset was 31 days. The Tb, ALT, and ALP were 7 mg/dL, 478, and 325 U/L at onset. Nearly all liver biopsies showed prominent cholestatic features. Resolution of AC-DILI, defined by return of Tb to <2.5 mg/dL, occurred on average 55 days after the peak value. Three female subjects required liver transplantation, and none died due to DILI. Conclusion AC-DILI causes a moderately severe, mixed hepatocellular–cholestatic injury, particularly in older men, unlike DILI in general, which predominates in women. Although often protracted, eventual apparent recovery is typical, particularly for men and usually in women, but three women required liver transplantation.Item Association of State Medicaid Expansion With Racial/Ethnic Disparities in Liver Transplant Wait-listing in the United States(JAMA, 2020-10-08) Nephew, Lauren D.; Mosesso, Kelly; Desai, Archita; Ghabril, Marwan; Orman, Eric S.; Patidar, Kavish R.; Kubal, Chandrashekhar; Noureddin, Mazen; Chalasani, Naga; Medicine, School of MedicineImportance Millions of Americans gained insurance through the state expansion of Medicaid, but several states with large populations of racial/ethnic minorities did not expand their programs. Objective To investigate the implications of Medicaid expansion for liver transplant (LT) wait-listing trends for racial/ethnic minorities. Design, Setting, and Participants A cohort study was performed of adults wait-listed for LT using the United Network of Organ Sharing database between January 1, 2010, and December 31, 2017. Poisson regression and a controlled, interrupted time series analysis were used to model trends in wait-listing rates by race/ethnicity. The setting was LT centers in the United States. Main Outcomes and Measures (1) Wait-listing rates by race/ethnicity in states that expanded Medicaid (expansion states) compared with those that did not (nonexpansion states) and (2) actual vs predicted rates of LT wait-listing by race/ethnicity after Medicaid expansion. Results There were 75 748 patients (median age, 57.0 [interquartile range, 50.0-62.0] years; 48 566 [64.1%] male) wait-listed for LT during the study period. The cohort was 8.9% Black and 16.4% Hispanic. Black patients and Hispanic patients were statistically significantly more likely to be wait-listed in expansion states than in nonexpansion states (incidence rate ratio [IRR], 1.54 [95% CI, 1.44-1.64] for Black patients and 1.21 [95% CI, 1.15-1.28] for Hispanic patients). After Medicaid expansion, there was a decrease in the wait-listing rate of Black patients in expansion states (annual percentage change [APC], −4.4%; 95% CI, −8.2% to −0.6%) but not in nonexpansion states (APC, 0.5%; 95% CI, −4.0% to 5.2%). This decrease was not seen when Black patients with hepatitis C virus (HCV) were excluded from the analysis (APC, 3.1%; 95% CI, −2.4% to 8.9%), suggesting that they may be responsible for this expansion state trend. Hispanic Medicaid patients without HCV were statistically significantly more likely to be wait-listed in the post–Medicaid expansion era than would have been predicted without Medicaid expansion (APC, 13.2%; 95% CI, 4.0%-23.2%). Conclusions and Relevance This cohort study found that LT wait-listing rates have decreased for Black patients with HCV in states that expanded Medicaid. Conversely, wait-listing rates have increased for Hispanic patients without HCV. Black patients and Hispanic patients may have benefited differently from Medicaid expansion.Item Black Adult Patients With Acute Liver Failure Are Sicker and More Likely to Undergo Liver Transplantation Than White Patients(Wiley, 2019) Nephew, Lauren; Zia, Zahra; Ghabril, Marwan; Orman, Eric; Lammert, Craig; Chalasani, Naga; Medicine, School of MedicineRacial and ethnic differences in the presentation and outcomes of patients wait‐listed with acute liver failure (ALF) have not been explored. Adult patients with ALF wait‐listed for liver transplantation (LT) from 2002 to 2016 were investigated using the United Network for Organ Sharing database. Clinical characteristics and causative etiologies were compared between white, black, Hispanic, and Asian patients with ALF who were wait‐listed as status 1. A competing risk analysis was used to explore differences in LT and wait‐list removal rates. Kaplan‐Meier survival curves were used to explore differences in 1‐year posttransplant survival. There were 8208 patients wait‐listed with a primary diagnosis of ALF; 4501 were wait‐listed as status 1 (55.3% of whites, 64.4% of blacks, 51.6% of Hispanics, 40.7% of Asians; P < 0.001). Black patients had higher bilirubin and Model for End‐Stage Liver Disease at wait‐listing than other groups. White patients were the most likely to have acetaminophen toxicity as a causative etiology, whereas black patients were the most likely to have autoimmune liver disease. Black patients were significantly more likely to undergo LT than white patients (hazard ratio, 1.20; 95% confidence interval, 1.08‐1.30). There was no difference in wait‐list removal because of death or clinical deterioration among racial/ethnic groups. The 1‐year posttransplant survival was lowest in black patients (79.6%) versus white (82.8%), Hispanic (83.9%), and Asian (89.3%) patients (P = 0.02). In conclusion, etiologies of ALF vary by race and ethnicity. Black patients with ALF were more likely to be wait‐listed as status 1 and undergo LT than white patients, but they were sicker at presentation. The 1‐year posttransplant survival rate was lowest among black patients.Item The confusion assessment method for the intensive care unit in patients with cirrhosis(Springer, 2015-08) Orman, Eric S.; Perkins, Anthony; Ghabril, Marwan; Khan, Babar A.; Chalasani, Naga; Boustani, Malaz A.; Department of Medicine, IU School of MedicineIn the intensive care unit (ICU), delirium is routinely measured with the widely-used, validated Confusion Assessment Method for the ICU (CAM-ICU), but CAM-ICU has not been studied in patients with cirrhosis. We studied a group of patients with cirrhosis to determine the relationship between delirium measured by CAM-ICU and clinical outcomes. Consecutive patients with cirrhosis admitted to the ICU from 2009 to 2012 were included in a retrospective cohort study. Patients were screened twice daily for coma and delirium during their ICU stay using the Richmond Agitation Sedation Scale (RASS) and CAM-ICU. The association between delirium/coma and mortality was determined using multiple logistic regression. RASS and CAM-ICU were also compared to a retrospective assessment of hepatic encephalopathy (HE). Of 91 patients with cirrhosis, 26 (28.6 %) developed delirium/coma. RASS/CAM-ICU had fair agreement with the HE assessment (κ 0.38). Patients with delirium/coma had numerically greater mortality in-hospital (23.1 vs. 7.7 %, p = 0.07) and at 90 days (30.8 vs. 18.5 %, p = 0.26), and they also had longer hospital length of stay (median 19.5 vs. 6 days, p < 0.001). Delirium/coma was associated with increased inpatient mortality, independent of disease severity (unadjusted OR 3.6; 95 % CI, 0.99-13.1; MELD-adjusted OR 5.4; 95 % CI, 1.3-23.8; acute physiology score-adjusted OR 2.2; 95 % CI, 0.53-8.9). Delirium/coma was also associated with longer length of stay after adjusting for disease severity. In critically ill patients with cirrhosis, delirium/coma as measured by the RASS and CAM-ICU is associated with increased mortality and hospital length of stay. For these patients, these measures provide valuable information and may be useful tools for clinical care. RASS and CAM-ICU need to be compared to HE-specific measures in future studies.Item Contemporary Trends in Hospitalizations for Comorbid Chronic Liver Disease and Substance Use Disorders(Wolters Kluwer, 2021-06-18) Desai, Archita P.; Greene, Marion; Nephew, Lauren D.; Orman, Eric S.; Ghabril, Marwan; Chalasani, Naga; Menachemi, Nir; Medicine, School of MedicineIntroduction: Chronic liver diseases (CLDs) and substance use disorders (SUDs) are increasingly prevalent and often coexist. Contemporary studies describing the characteristics and hospitalization trends of those with comorbid CLD-SUD are lacking. We aimed to characterize a population-based cohort with comorbid CLD-SUD and describe trends in these hospitalizations over time by individual-level characteristics. Methods: We performed a cross-sectional analysis of the National Inpatient Sample from 2005 through 2017. Diagnosis codes were used to identify adult hospitalizations with CLD, SUD, or both. Bivariate and multivariate analyses were used to make comparisons between diagnosis categories. Unadjusted and age-adjusted trends in these hospitalizations were described over time. Results: Of 401,867,749 adult hospital discharges, 3.2% had CLD-only and 1.7% had comorbid CLD-SUD. Compared with CLD-only, comorbid CLD-SUD hospitalizations resulted in higher inpatient mortality (3.1% vs 2.4%, P < 0.001) and were associated with younger age, male sex, Native American race, and urban and Western US location. Over time, comorbid hospitalizations grew 34%, and the demographics shifted with larger increases in hospitalization rates seen in younger individuals, women, Native Americans, and those publicly insured. In comorbid hospitalizations, alcoholic SUD and CLD decreased, but drug SUDs and nonalcoholic fatty liver diseases are fast-growing contributors. Discussion: In this comprehensive analysis of US hospitalizations, comorbid CLD-SUD hospitalizations are increasing over time and lead to higher inpatient mortality than CLD alone. We further characterize the changing demographics of these hospitalizations, providing a contemporary yet inclusive look at comorbid CLD-SUD hospitalizations. These data can guide interventions needed to improve the poor outcomes suffered by this growing population.Item A dedicated paracentesis clinic decreases healthcare utilization for serial paracenteses in decompensated cirrhosis(Springer Nature, 2018-08) Cheng, Yao-Wen; Sandrasegaran, Kumar; Cheng, Katherine; Shah, Angela; Ghabril, Marwan; Berry, William; Lammert, Craig; Chalasani, Naga; Orman, Eric S.; Radiology and Imaging Sciences, School of MedicinePURPOSE: The purpose of the study is to describe the effect of a dedicated paracentesis clinic on healthcare utilization by patients with decompensated cirrhosis and refractory ascites. METHODS: This Institutional Review Board-approved retrospective study identified cirrhotic patients receiving paracenteses over a 6-month period before and after creating the paracentesis clinic. Patients were followed for 12 months to collect outcome data including characteristics of subsequent hospitalizations and paracenteses. Logistic regression was used to examine the association between the paracentesis clinic and outcomes. RESULTS: There were 183 patients and 1364 paracenteses performed during the study time period. Age, gender, cirrhosis etiology, MELD, Child-Pugh, and Charlson comorbidity index were comparable between the two groups. Rates of mortality, transplant, and hospitalization were also similar during 1 year follow-up. After establishment of the paracentesis clinic, median paracenteses per patient increased from 2 (IQR 1-7) to 4 (IQR 2-11) (P = 0.01); albumin replacement after paracenteses ≥ 5 L improved from 76.3% to 91.7% (P < 0.001); and the fraction of outpatient paracenteses performed in the emergency department decreased from 13.4% to 3.8% (P < 0.001). Major complications remained negligible at 0.81% across both time periods. While fewer patients were admitted for ascites after the paracentesis clinic (39.6% vs. 20.8%, P = 0.009), more patients had acute kidney injury (AKI) during follow-up (47.2% vs. 65.9%, P = 0.02), with a trend towards more AKI admissions (22.6% vs. 35.4%, P = 0.09). CONCLUSION: A dedicated paracentesis clinic can improve access and wait times, while also reducing admissions for ascites and paracenteses performed in the emergency department.Item Development and Validation of Model Consisting of Comorbidity Burden to Calculate Risk of Death Within 6 months for Patients With Suspected Drug-Induced Liver Injury(Elsevier, 2019-11) Ghabril, Marwan; Gu, Jiezhun; Yoder, Lindsay; Corbito, Laura; Ringel, Amit; Beyer, Christian D.; Vuppalanchi, Raj; Barnhart, Huiman; Hayashi, Paul H.; Chalasani, Naga; Medicine, School of MedicineBackground & Aims: Patients with drug-induced liver injury (DILI) frequently have comorbid conditions, but the effects of non-liver comorbidities on outcome is not well understood. We investigated the association between co-morbidity burden and outcomes of patients with DILI, and developed and validated a model to calculate risk of death within 6 months. Methods: A multiple logistic regression model identified variables independently associated with death within 6 months of presenting with suspected DILI (6-month mortality) for 306 patients enrolled in the DILIN prospective study at Indiana University (discovery cohort). The model was validated using data from 247 patients with suspected DILI enrolled in the same study at the University of North Carolina (validation cohort). Medical comorbidity burden was calculated using the Charlson comorbidity index—patients with scores higher than 2 were considered to have significant comorbidities. Results: Six-month mortality was 8.5% in the discovery cohort and 4.5% in the validation cohort. In the discovery cohort, significant comorbidities (odds ratio [OR], 5.4; 95% CI 2.1 – 13.8), model for end-stage liver disease score (OR, 1.11; 95% CI, 1.04–1.17), and serum level of albumin at presentation (OR, 0.39; 95% CI, 0.2–0.76) were independently associated with 6-month mortality. A model based on these 3 variables identified patients who died within 6 months with c-statistic values of 0.89 (95% CI, 0.86–0.94) in the discovery cohort and 0.91 (95% CI, 0.83–0.99) in the validation cohort. We developed a web-based calculator to determine risk of death within 6 months for patients with suspected DILI for use in the clinic. Conclusions: We developed and validated a model based on comorbidity burden, model for end-stage liver disease score, and serum level of albumin that predicts 6-month mortality in patients with suspected DILI.Item Does providing routine liver volume assessment add value when performing CT surveillance in cirrhotic patients?(Springer, 2019-07-29) Patel, Milan; Puangsricharoen, Pimpitcha; Arshad, Hafiz Muhammad Sharjeel; Garrison, Sam; Techasatian, Witina; Ghabril, Marwan; Sandrasegaran, Kumar; Liangpunsakul, Suthat; Tann, Mark; Medicine, School of MedicineBackground: The measurement of liver volume (LV) is considered to be an effective prognosticator for postoperative liver failure in patients undergoing hepatectomy. It is unclear whether LV can be used to predict mortality in cirrhotic patients. Methods: We enrolled 584 consecutive cirrhotic patients who underwent computerized topography (CT) of the abdomen for hepatocellular carcinoma surveillance and 50 age, gender, race, and BMI-matched controls without liver disease. Total LV (TLV), functional LV (FLV), and segmental liver volume (in cm3) were measured from CT imaging. Cirrhotic subjects were followed until death, liver transplantation, or study closure date of July 31, 2016. The survival data were assessed with log-rank statistics and independent predictors of survival were performed using Cox hazards model. Results: Cirrhotic subjects had significantly lower TLV, FLV, and segmental (all except for segments 1, 6, 7) volume when compared to controls. Subjects presenting with hepatic encephalopathy had significantly lower TLV and FLV than those without HE (p=0.002). During the median follow up of 1,145 days, 112 (19%) subjects were transplanted and 131 (23%) died. TLV and FLV for those who survived were significantly higher than those who were transplanted or dead (TLV:1740 vs 1529 vs 1486, FLV 1691 vs 1487 vs 1444,p <0.0001). In the Cox regression model, age, MELD score, TLV or FLV were independent predictors of mortality. Conclusion: Baseline liver volume is an independent predictor of mortality in subjects with cirrhosis. Therefore it may be useful to provide these data while performing routine surveillance CT scan as an important added value. Further studies are needed to validate these findings and to better understand their clinical utility.Item Eight‐Fold Increase in Dietary Supplement–Related Liver Failure Leading to Transplant Waitlisting Over the Last Quarter Century in the United States(Wiley, 2022-02) Ghabril, Marwan; Ma, Jiayi; Patidar, Kavish R.; Nephew, Lauren; Desai, Archita P.; Orman, Eric S.; Vuppalanchi, Raj; Kubal, Shekhar; Chalasani, Naga; Medicine, School of MedicineWe investigated the trends in listing and outcomes of drug-induced acute liver failure (DIALF) over the last quarter century in the United States using the United Network for Organ Sharing (UNOS) database. We examined waitlisted patients in the UNOS database between 1995 and 2020 with a diagnosis of DIALF and assessed trends in etiologies, demographic and clinical characteristics, and outcomes over 3 periods: 1995-2003, 2004-2012, and 2013-2020. Patients with DIALF and cirrhosis were classified as drug-induced acute-on-chronic liver failure. Implicated agents including acetaminophen (APAP) and herbal or dietary supplements (HDSs) were ascertained. There were 2146 individuals with DIALF during the study period. The observed demographic trends between the earliest and latest period included fewer pediatric patients (18.8% to 13.5%) but with an increasing number of males in non-APAP DIALF (31.8% to 41.4%) and increased racial diversity in APAP DIALF. Antimicrobials remained the most common non-APAP agents across all periods, but antiepileptics, propylthiouracil, and mushroom poisoning decreased, while HDSs markedly increased from 2.9% to 24.1% of all non-APAP DIALF patients. The overall 5-year post-liver transplantation (LT) patient survival improved significantly over the 3 periods (69.9% to 77.4% to 83.3%) and was evident for both APAP and non-APAP DIALF. Over the last quarter century, there has been an 8-fold increase in HDS-related liver failure necessitating waitlisting for liver transplantation in the United States. There are other important temporal trends during the study period, including improved survival following LT among both APAP and non-APAP DIALF patients.
