Item Burden of Fatty Liver and Hepatic Fibrosis in Persons with HIV: A Diverse Cross-sectional US Multicenter Study(Wolters Kluwer, 2023) Gawrieh, Samer; Lake, Jordan E.; Debroy, Paula; Sjoquist, Julia A.; Robison, Montreca; Tann, Mark; Akisik, Fatih; Bhamidipalli, Surya S.; Saha, Chandan K.; Zachary, Kimon; Robbins, Gregory K.; Gupta, Samir K.; Chung, Raymond T.; Chalasani, Naga; Corey, Kathleen E.; Radiology and Imaging Sciences, School of MedicineBackground aims: The current prevalence of fatty liver disease (FLD) due to alcohol-associated (AFLD) and nonalcoholic (NAFLD) origins in US persons with HIV (PWH) is not well defined. We prospectively evaluated the burden of FLD and hepatic fibrosis in a diverse cohort of PWH. Approach results: Consenting participants in outpatient HIV clinics in 3 centers in the US underwent detailed phenotyping, including liver ultrasound and vibration-controlled transient elastography for controlled attenuation parameter and liver stiffness measurement. The prevalence of AFLD, NAFLD, and clinically significant and advanced fibrosis was determined. Univariate and multivariate logistic regression models were used to evaluate factors associated with the risk of NAFLD. Of 342 participants, 95.6% were on antiretroviral therapy, 93.9% had adequate viral suppression, 48.7% (95% CI 43%-54%) had steatosis by ultrasound, and 50.6% (95% CI 45%-56%) had steatosis by controlled attenuation parameter ≥263 dB/m. NAFLD accounted for 90% of FLD. In multivariable analysis, old age, higher body mass index, diabetes, and higher alanine aminotransferase, but not antiretroviral therapy or CD4 + cell count, were independently associated with increased NAFLD risk. In all PWH with fatty liver, the frequency of liver stiffness measurement 8-12 kPa was 13.9% (95% CI 9%-20%) and ≥12 kPa 6.4% (95% CI 3%-11%), with a similar frequency of these liver stiffness measurement cutoffs in NAFLD. Conclusions: Nearly half of the virally-suppressed PWH have FLD, 90% of which is due to NAFLD. A fifth of the PWH with FLD has clinically significant fibrosis, and 6% have advanced fibrosis. These data lend support to systematic screening for high-risk NAFLD in PWH.Item Changing Trends of Cirrhotic and Noncirrhotic Hepatocellular Carcinoma in the Era of Directly-Acting Antiviral Agents(Wolters Kluwer, 2021-11-03) Mathur, Karan; Mazhar, Areej; Patel, Milin; Dakhoul, Lara; Burney, Heather; Liu, Hao; Nephew, Lauren; Chalasani, Naga; deLemos, Andrew; Gawrieh, Samer; Medicine, School of MedicineIntroduction: The impact of direct-acting antivirals (DAAs) for hepatitis C virus (HCV) on burden of cirrhotic and noncirrhotic hepatocellular carcinoma (HCC) has not been examined. We assessed recent trends in liver disease etiologies of HCC and proportion of noncirrhotic HCC since DAAs introduction. Methods: Clinical characteristics including presence or absence of underlying cirrhosis were collected from 2,623 patients diagnosed with HCC between 2009 and 2019 at 2 large US centers. Logistic regression was performed to investigate the annual trends of HCC due to different liver diseases and proportions of noncirrhotic cases. Results: In the DAA era (2014-2019), annual decline in HCV-HCC (odds ratio [OR] = 0.93, 95% confidence interval [CI] 0.88-0.99, P = 0.019), without change in trends of other liver diseases-related HCC, was observed. Annual increase in noncirrhotic HCC (OR 1.13, 95% CI 1.03-1.23, P = 0.009) and decline in cirrhotic HCC (OR 0.89, 95% CI 0.81-0.97, P = 0.009) along with similar trends for HCV-HCC-increase in noncirrhotic cases (OR 1.35, 95% CI 1.08-1.69, P = 0.009) and decrease in cirrhotic cases (OR 0.92, 95% CI 0.86-0.98, P = 0.012)-were observed during the DAA era. Compared with the pre-DAA era, HCC resection rate increased (10.7% vs 14.0%, P = 0.013) whereas liver transplantation rate decreased (15.1% vs 12.0%, P = 0.023) in the DAA era. Discussion: Since introduction of DAAs, proportions of cirrhotic HCC have decreased, whereas proportions of noncirrhotic HCC have increased. These new trends were associated with change in utilization of liver resection and transplantation for HCC. The impact of changing patterns of DAA use on these trends will require further study.Item Cirrhosis regression is associated with improved clinical outcomes in patients with nonalcoholic steatohepatitis(Wiley, 2022) Sanyal, Arun J.; Anstee, Quentin M.; Trauner, Michael; Lawitz, Eric J.; Abdelmalek, Manal F.; Ding, Dora; Han, Ling; Jia, Catherine; Huss, Ryan S.; Chung, Chuhan; Wong, Vincent Wai-Sun; Okanoue, Takeshi; Romero-Gomez, Manuel; Muir, Andrew J.; Afdhal, Nezam H.; Bosch, Jaime; Goodman, Zachary; Harrison, Stephen A.; Younossi, Zobair M.; Myers, Robert P.; Medicine, School of MedicineBackground and aims: Surrogate endpoints that predict complications are necessary for assessment and approval of NASH therapies. We assessed associations between histologic and noninvasive tests (NITs) of fibrosis with liver-related complications in patients with NASH cirrhosis. Approach and results: Patients with compensated cirrhosis due to NASH were enrolled in two placebo-controlled trials of simtuzumab and selonsertib. Liver fibrosis at baseline and week 48 (W48) was staged by NASH Clinical Research Network (CRN) and Ishak classifications and a machine learning (ML) approach, hepatic collagen and alpha-smooth muscle actin (α-SMA) expression were quantified by morphometry, liver stiffness (LS) was measured by transient elastography, and serum NITs (enhanced liver fibrosis [ELF], NAFLD fibrosis score [NFS], and Fibrosis-4 index [FIB-4]) were calculated. Cox regression determined associations between these parameters at baseline and their changes over time with adjudicated liver-related clinical events. Among 1,135 patients, 709 (62%) had Ishak stage 6 fibrosis, and median ELF and LS were 10.66 and 21.1 kPa, respectively. During a median follow-up of 16.6 months, 71 (6.3%) had a liver-related event; associated baseline factors included Ishak stage 6 fibrosis, and higher hepatic collagen, α-SMA expression, ML-based fibrosis parameters, LS, ELF, NFS, and FIB-4. Cirrhosis regression observed in 16% (176/1,135) between BL and W48 was associated with a lower risk of events versus nonregression (1.1% [2/176] vs. 7.2% [69/957]; HR, 0.16; 95% CI, 0.04, 0.65 [p = 0.0104]). Conversely, after adjustment for baseline values, increases in hepatic collagen, α-SMA, ML-based fibrosis parameters, NFS, and LS were associated with an increased risk of events. Conclusions: In patients with compensated cirrhosis due to NASH, regression of fibrosis is associated with a reduction in liver-related complications. These data support the utility of histologic fibrosis regression and NITs as clinical trial endpoints for NASH cirrhosis.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 Editorial: Updated epidemiology of steatotic liver disease in people with HIV in the United States - authors’ reply(Wiley, 2024) Gawrieh, Samer; Sulkowski, Mark; Chalasani, Naga; Loomba, Rohit; Medicine, School of MedicineItem FGF1 Signaling Modulates Biliary Injury and Liver Fibrosis in the Mdr2-/- Mouse Model of Primary Sclerosing Cholangitis(Wolters Kluwer, 2022) O’Brien, April; Zhou, Tianhao; White, Tori; Medford, Abigail; Chen, Lixian; Kyritsi, Konstantina; Wu, Nan; Childs, Jonathan; Stiles, Danaleigh; Ceci, Ludovica; Chakraborty, Sanjukta; Ekser, Burcin; Baiocchi, Leonardo; Carpino, Guido; Gaudio, Eugenio; Wu, Chaodong; Kennedy, Lindsey; Francis, Heather; Alpini, Gianfranco; Glaser, Shannon; Medicine, School of MedicineFibroblast growth factor 1 (FGF1) belongs to a family of growth factors involved in cellular growth and division. MicroRNA 16 (miR-16) is a regulator of gene expression, which is dysregulated during liver injury and insult. However, the role of FGF1 in the progression of biliary proliferation, senescence, fibrosis, inflammation, angiogenesis, and its potential interaction with miR-16, are unknown. In vivo studies were performed in male bile duct-ligated (BDL, 12-week-old) mice, multidrug resistance 2 knockout (Mdr2-/-) mice (10-week-old), and their corresponding controls, treated with recombinant human FGF1 (rhFGF1), fibroblast growth factor receptor (FGFR) antagonist (AZD4547), or anti-FGF1 monoclonal antibody (mAb). In vitro, the human cholangiocyte cell line (H69) and human hepatic stellate cells (HSCs) were used to determine the expression of proliferation, fibrosis, angiogenesis, and inflammatory genes following rhFGF1 treatment. PSC patient and control livers were used to evaluate FGF1 and miR-16 expression. Intrahepatic bile duct mass (IBDM), along with hepatic fibrosis and inflammation, increased in BDL mice treated with rhFGF1, with a corresponding decrease in miR-16, while treatment with AZD4547 or anti-FGF1 mAb decreased hepatic fibrosis, IBDM, and inflammation in BDL and Mdr2-/- mice. In vitro, H69 and HSCs treated with rhFGF1 had increased expression of proliferation, fibrosis, and inflammatory markers. PSC samples also showed increased FGF1 and FGFRs with corresponding decreases in miR-16 compared with healthy controls. Conclusion: Our study demonstrates that suppression of FGF1 and miR-16 signaling decreases the presence of hepatic fibrosis, biliary proliferation, inflammation, senescence, and angiogenesis. Targeting the FGF1 and miR-16 axis may provide therapeutic options in treating cholangiopathies such as PSC.Item Focused Education Increases Hepatocellular Cancer Screening in Patients with Cirrhosis Regardless of Functional Health Literacy(Springer Nature, 2021) Shaw, Jawaid; Patidar, Kavish R.; Reuter, Bradley; Hajezifar, Navid; Dharel, Narayan; Wade, James B.; Bajaj, Jasmohan S.; Medicine, School of MedicineBackground: Health education interventions are successful in modifying lifestyle. Functional health literacy (FHL) can determine patient adherence to clinic visits and procedures and may adversely impact the success of these interventions. Aims: We sought to evaluate the hypothesis that a health education intervention would improve compliance with hepatocellular cancer (HCC) screening and that poor FHL would reduce such compliance. Methods: We assessed FHL using a short version test of functional health literacy in adults (STOFHLA). Cirrhotic patients free of HCC were prospectively enrolled from clinics and provided an educational intervention consisting of focused physician-led discussion regarding cirrhosis and HCC, along with written material on these topics for the subject to review at home. Patients were subsequently followed for 6 months (prospective time period), and the same cohort's clinic/HCC screening behavior between 6 and 12 months prior to the educational intervention (retrospective time period) was compared. Results: In total, 104 cirrhotic patients (age 60.01 ± 8.58 years, 80% men, MELD 12.70 ± 5.76) were included. Of these, 89 (85.57%) of patients had educational level 12th grade and higher. There were 76% (n = 79) with adequate, while 24% (n = 25) had inadequate/marginal FHL on S-TOHFLA. The number of HCC-related imaging increased from 59 (56.7%) to 86 (82.6%, p < 0.0001) post-education in the prospective compared to prior time period which was similar regardless of FHL. Conclusions: While the educational intervention was successful in improving compliance with HCC screenings, FHL status did not impact the power of this intervention. Hence, the combination of specific verbal information, along with targeted written material, improved compliance with clinic visits and liver imaging for HCC.Item Heterogeneous liver on research ultrasound identifies children with cystic fibrosis at high risk of advanced liver disease(Elsevier, 2023) Siegel, Marilyn J.; Leung, Daniel H.; Molleston, Jean P.; Ye, Wen; Paranjape, Shruti M.; Freeman, A. Jay; Palermo, Joseph J.; Stoll, Janis; Masand, Prakash; Karmazyn, Boaz; Harned, Roger; Ling, Simon C.; Navarro, Oscar M.; Karnsakul, Wikrom; Alazraki, Adina; Schwarzenberg, Sarah Jane; Towbin, Alex J.; Alonso, Estella M.; Nicholas, Jennifer L.; Green, Nicole; Otto, Randolph K.; Magee, John C.; Narkewicz, Michael R.; CFLD Network; Pediatrics, School of MedicineBackground: This study examines whether heterogeneous (HTG) pattern on liver ultrasound (US) identifies children at risk for advanced cystic fibrosis liver disease (aCFLD). Methods: Prospective 6-year multicenter case-controlled cohort study. Children with pancreatic insufficient cystic fibrosis (CF) aged 3-12 years without known cirrhosis underwent screening US. Participants with HTG were matched (by age, Pseudomonas infection status and center) 1:2 with participants with normal (NL) US pattern. Clinical status and laboratory data were obtained annually and US bi-annually for 6 years. Primary endpoint was development of nodular (NOD) US pattern consistent with aCFLD. Results: 722 participants underwent screening US, with 65 HTG and 592 NL. Final cohort included 55 HTG and 116 NL with ≥ 1 follow-up US. ALT, AST, GGTP, FIB-4, GPR and APRI were higher, and platelets were lower in HTG compared to NL. HTG had a 9.5-fold increased incidence (95% confidence interval [CI]:3.4, 26.7, p<0.0001, 32.7% vs 3.4%) of NOD versus NL. HTG had a sensitivity of 82% and specificity of 75% for subsequent NOD. Negative predictive value of a NL US for subsequent NOD was 96%. Multivariate logistic prediction model that included baseline US, age, and log(GPR) improved the C-index to 0.90 compared to only baseline US (C-index 0.78). Based on survival analysis, 50% of HTG develop NOD after 8 years. Conclusions: Research US finding of HTG identifies children with CF with a 30-50% risk for aCFLD. A score based on US pattern, age and GPR may refine the identification of individuals at high risk for aCFLD.Item HMGB2 is a potential diagnostic marker and therapeutic target for liver fibrosis and cirrhosis(Wolters Kluwer, 2023-11-06) Huang, Yi; Liangpunsakul, Suthat; Rudraiah, Swetha; Ma, Jing; Keshipeddy, Santosh K.; Wright, Dennis; Costa, Antonio; Burgess, Diane; Zhang, Yuxia; Huda, Nazmul; Wang, Li; Yang, Zhihong; Medicine, School of MedicineBackground: High mobility group proteins 1 and 2 (HMGB1 and HMGB2) are 80% conserved in amino acid sequence. The function of HMGB1 in inflammation and fibrosis has been extensively characterized. However, an unaddressed central question is the role of HMGB2 on liver fibrosis. In this study, we provided convincing evidence that the HMGB2 expression was significantly upregulated in human liver fibrosis and cirrhosis, as well as in several mouse liver fibrosis models. Methods: The carbon tetrachloride (CCl4) induced liver fibrosis mouse model was used. AAV8-Hmgb2 was utilized to overexpress Hmgb2 in the liver, while Hmgb2-/- mice were used for loss of function experiments. The HMGB2 inhibitor inflachromene and liposome-shHMGB2 (lipo-shHMGB2) were employed for therapeutic intervention. Results: The serum HMGB2 levels were also markedly elevated in patients with liver fibrosis and cirrhosis. Deletion of Hmgb2 in Hmgb2-/- mice or inhibition of HMGB2 in mice using a small molecule ICM slowed the progression of CCl4-induced liver fibrosis despite constant HMGB1 expression. In contrast, AAV8-mediated overexpression of Hmgb2 enchanced CCl4-incuded liver fibrosis. Primary hepatic stellate cells (HSCs) isolated from Hmgb2-/- mice showed significantly impaired transdifferentiation and diminished activation of α-SMA, despite a modest induction of HMGB1 protein. RNA-seq analysis revealed the induction of top 45 CCl4-activated genes in multiple signaling pathways including integrin signaling and inflammation. The activation of these genes by CCl4 were abolished in Hmgb2-/- mice or in ICM-treated mice. These included C-X3-C motif chemokine receptor 1 (Cx3cr1) associated with inflammation, cyclin B (Ccnb) associated with cell cycle, DNA topoisomerase 2-alpha (Top2a) associated with intracellular component, and fibrillin (Fbn) and fibromodulin (Fmod) associated with extracellular matrix. Conclusion: We conclude that HMGB2 is indispensable for stellate cell activation. Therefore, HMGB2 may serve as a potential therapeutic target to prevent HSC activation during chronic liver injury. The blood HMGB2 level may also serve as a potential diagnostic marker to detect early stage of liver fibrosis and cirrhosis in humans.Item Hospital Readmissions in Patients with Cirrhosis: A Systematic Review(Wiley, 2018-04-25) Orman, Eric S.; Ghabril, Marwan; Emmett, Thomas W.; Chalasani, Naga; Medicine, School of MedicineBACKGROUND: Hospital readmission is a significant problem for patients with complex chronic illnesses such as liver cirrhosis. PURPOSE: We aimed to describe the range of readmission risk in patients with cirrhosis and the impact of the model for end-stage liver disease (MELD) score. DATA SOURCES: We conducted a systematic review of studies identified in Ovid MEDLINE, PubMed, EMBASE, CINAHL, the Cochrane Library, Scopus, Google Scholar, and ClinicalTrials.gov from 2000 to May 2017. STUDY SELECTION: We examined studies that reported early readmissions (up to 90 days) in patients with cirrhosis. Studies were excluded if they did not examine the association between readmission and at least 1 variable or intervention. DATA EXTRACTION: Two reviewers independently extracted data on study design, setting, population, interventions, comparisons, and detailed information on readmissions. DATA SYNTHESIS: Of the 1363 records reviewed, 26 studies met the inclusion and exclusion criteria. Of these studies, 21 were retrospective, and there was significant variation in the inclusion and exclusion criteria. The pooled estimate of 30-day readmissions was 26%(95% confidence interval [CI], 22%-30%). Few studies examined readmission preventability or the relationship between readmissions and social determinants of health. Reasons for readmission were highly variable. An increased MELD score was associated with readmissions in most studies. Readmission was associated with increased mortality. CONCLUSIONS: Hospital readmissions frequently occur in patients with cirrhosis and are associated with liver disease severity. The impact of functional and social factors on readmissions is unclear.
