    Nutrition and Physical Activity in Nonalcoholic Fatty Liver Disease
    (2016) OLIVEIRA, Claudia P.; SANCHES, Priscila de Lima; ABREU-SILVA, Erlon Oliveira de; MARCADENTI, Aline
    Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide and it is associated with other medical conditions such as diabetes mellitus, metabolic syndrome, and obesity. The mechanisms of the underlying disease development and progression are not completely established and there is no consensus concerning the pharmacological treatment. In the gold standard treatment for NAFLD weight loss, dietary therapy, and physical activity are included. However, little scientific evidence is available on diet and/or physical activity and NAFLD specifically. Many dietary approaches such asMediterranean and DASH diet are used for treatment of other cardiometabolic risk factors such as insulin resistance and type-2 diabetes mellitus (T2DM), but on the basis of its components their role in NAFLD has been discussed. In this review, the implications of current dietary and exercise approaches, including Brazilian and other guidelines, are discussed, with a focus on determining the optimal nonpharmacological treatment to prescribe for NAFLD.

    Randomized clinical trial: benefits of aerobic physical activity for 24 weeks in postmenopausal women with nonalcoholic fatty liver disease
    (2016) REZENDE, Rosamar E. F.; DUARTE, Sebastiao M. B.; STEFANO, Jose T.; ROSCHEL, Hamilton; GUALANO, Bruno; PINTO, Ana L. de Sa; VEZOZZO, Denise C. P.; CARRILHO, Flair J.; OLIVEIRA, Claudia P.
    Objective: The aim of the study was to evaluate the effectiveness of aerobic physical activity in reducing the frequency of hepatic steatosis and metabolic and cardiovascular risk in postmenopausal women with nonalcoholic fatty liver disease (NAFLD). Methods: Forty sedentary postmenopausal women (mean age 55.3 +/- 8.0 y) with biopsy-proven NAFLD were randomly divided into two groups: an exercising group (19 participants) and a control group (nonexercising, 21 participants). The exercise group underwent a supervised aerobic physical activity program of 120 min/wk for 24 weeks. The anthropometric parameters; body composition; hepatic, lipid, and glycemic profiles; homeostasis model assessment of insulin resistance index; cytokines; transient elastography (FibroScan; liver stiffness/controlled attenuation parameter); and cardiopulmonary exercise test were evaluated at baseline and after 24 weeks of protocol. Results: At baseline there were no significant differences in anthropometric, metabolic, and inflammatory parameters-stiffness and liver fat content by FibroScan between the groups. After 24 weeks, we observed a decrease of waist circumference, an increase of high-density lipoprotein cholesterol levels (P < 0.05), and improved cardiopulmonary functional capacity in the exercise group. In addition, the controlled attenuation parameter analysis showed no significant decrease of hepatic steatosis in the exercise group. With regard to the systemic inflammation, there were, however, no significant differences in the cytokines between the groups. Conclusions: An aerobic physical activity program of 24 weeks in NAFLD postmenopausal women showed improvement in some variables such as waist circumference, high-density lipoprotein cholesterol, and cardiopulmonary performance that may be beneficial in improving cardiovascular risk factors in this population.

    (2021) PINYOL, Roser; TORRECILLA, Sara; WANG, Huan; MONTIRONI, Carla; PIQUE-GILI, Marta; TORRES-MARTIN, Miguel; WEI-QIANG, Leow; WILLOUGHBY, Catherine E.; RAMADORI, Pierluigi; ANDREU-OLLER, Carmen; TAIK, Patricia; LEE, Youngmin A.; MOEINI, Agrin; PEIX, Judit; FAURE-DUPUY, Suzanne; RIEDL, Tobias; SCHUEHLE, Svenja; OLIVEIRA, Claudia P.; ALVES, Venancio A.; BOFFETTA, Paolo; LACHENMAYER, Anja; ROESSLER, Stephanie; MINGUEZ, Beatriz; SCHIRMACHER, Peter; DUFOUR, Jean-Francois; THUNG, Swan N.; REEVES, Helen L.; CARRILHO, Flair J.; CHANG, Charissa; V, Andrew Uzilov; HEIKENWALDER, Mathias; SANYAL, Arun; FRIEDMAN, Scott L.; SIA, Daniela; LLOVET, Josep M.
    Background and Aims: Non-alcoholic steatohepatitis (NASH)-related hepatocellular carcinoma (HCC) is increasing globally, but its molecular features are not well defined. We aimed to identify unique molecular traits characterising NASH-HCC compared to other HCC aetiologies. Methods: We collected 80 NASH-HCC and 125 NASH samples from 5 institutions. Expression array (n = 53 NASH-HCC; n = 74 NASH) and whole exome sequencing (n = 52 NASH-HCC) data were compared to HCCs of other aetiologies (n = 184). Three NASH-HCC mouse models were analysed by RNA-seq/expression-array (n = 20). Activin A receptor type 2A (ACVR2A) was silenced in HCC cells and proliferation assessed by colorimetric and colony formation assays. Results: Mutational profiling of NASH-HCC tumours revealed TERT promoter (56%), CTNNB1 (28%), TP53 (18%) and ACVR2A (10%) as the most frequently mutated genes. ACVR2A mutation rates were higher in NASH-HCC than in other HCC aetiologies (10% vs. 3%, p <0.05). In vitro, ACVR2A silencing prompted a significant increase in cell proliferation in HCC cells. We identified a novel mutational signature (MutSig-NASH-HCC) significantly associated with NASH-HCC (16% vs. 2% in viral/alcohol-HCC, p = 0.03). Tumour mutational burden was higher in non-cirrhotic than in cirrhotic NASH-HCCs (1.45 vs. 0.94 mutations/megabase; p <0.0017). Compared to other aetiologies of HCC, NASH-HCCs were enriched in bile and fatty acid signalling, oxidative stress and inflammation, and presented a higher fraction of Wnt/ TGF-beta proliferation subclass tumours (42% vs. 26%, p = 0.01) and a lower prevalence of the CTNNB1 subclass. Compared to other aetiologies, NASH-HCC showed a significantly higher prevalence of an immunosuppressive cancer field. In 3 murine models of NASH-HCC, key features of human NASH-HCC were preserved. Conclusions: NASH-HCCs display unique molecular features including higher rates of ACVR2A mutations and the presence of a newly identified mutational signature. Lay summary: The prevalence of hepatocellular carcinoma (HCC) associated with non-alcoholic steatohepatitis (NASH) is increasing globally, but its molecular traits are not well characterised. In this study, we uncovered higher rates of ACVR2A mutations (10%) - a potential tumour suppressor - and the presence of a novel mutational signature that characterises NASH-related HCC.

    Cardiovascular risk, atherosclerosis and metabolic syndrome after liver transplantation: a mini review
    (2013) OLIVEIRA, Claudia Pinto Marques Souza de; STEFANO, Jose Tadeu; ALVARES-DA-SILVA, Mario Reis
    Liver transplantation is the standard of care for acute and chronic end-stage liver disease. Advances in medical therapy and surgical techniques have transformed the long-term survival of liver-transplant (LT) recipients. The prevalence of post-transplant cardiovascular complications has been rising with increased life expectancy after liver transplantation. Currently, deaths related to cardiovascular complications are one of the main causes of long-term mortality in LT recipients, as cardiovascular disease is the reason of 19-42% of non-liver-related mortality after transplant. On the other hand, metabolic syndrome is common among LT recipients before and after transplantation. In fact, their components (abdominal obesity, diabetes mellitus, hypertension and dyslipidemia) are often exacerbated by transplant-specific factors, such as immunosuppression, inappropriate diet, smoking and a sedentary lifestyle, and add a significant risk of developing atherosclerosis. These aspects are discussed in this article.

    Association of UCP3 Polymorphisms with Nonalcoholic Steatohepatitis and Metabolic Syndrome in Nonalcoholic Fatty Liver Disease Brazilian Patients
    (2022) TODA-OTI, Karla Sawada; STEFANO, Jose Tadeu; CAVALEIRO, Ana Mercedes; CARRILHO, Flair Jose; CORREA-GIANELLA, Maria Lucia; OLIVEIRA, Claudia Pinto Marques de Souza de
    Background: We investigated the possible association of uncoupling protein 3 gene (UCP3) single nucleotide polymorphisms (SNPs) with nonalcoholic steatohepatitis (NASH) and metabolic syndrome (MetS) in nonalcoholic fatty liver disease (NAFLD) Brazilian patients.Methods: UCP3 SNPs rs1726745, rs3781907, and rs11235972 were genotyped in 158 biopsy-proven NAFLD Brazilian patients. Statistics was performed with JMP, R, and SHEsis softwares.Results: The TT genotype of rs1726745 was associated with less occurrence of MetS (P = 0.006) and with lower body mass index (BMI) in the entire NAFLD sample (P = 0.01) and in the NASH group (P = 0.02). The rs1726745-T was associated with lower values of AST (P = 0.001), ALT (P = 0.0002), triglycerides (P = 0.01), and total cholesterol (P = 0.02) in the entire NAFLD sample. Between groups, there were lower values of aminotransferases strictly in individuals with NASH (AST, P = 0.002; ALT, P = 0.0007) and with MetS (AST, P = 0.002; ALT, P = 0.001). The rs3781907-G was associated with lower GGT elevation values in the entire NAFLD sample (P = 0.002), in the NASH group (P = 0.004), and with MetS group (P = 0.003) and with protection for advanced fibrosis (P = 0.01). The rs11235972-A was associated with lower GGT values in the entire NAFLD sample (P = 0.006) and in the NASH group (P = 0.01) and with MetS group (P = 0.005), with fibrosis absence (P = 0.01) and protection for advanced fibrosis (P = 0.01). The TAA haplotype was protective for NASH (P = 0.002), and TGG haplotype was protective for MetS (P = 0.01).Conclusion: UCP3 gene variants were associated with protection against NASH and MetS, in addition to lower values of liver enzymes, lipid profile, BMI and, lesser fibrosis severity in the studied population.

    Evolution of Biomarkers of Atherogenic Risk in Liver Transplantation Recipients
    (2018) LINHARES, L. M. C.; OLIVEIRA, C. P.; ALVARES-DA-SILVA, M. R.; STEFANO, J. T.; BARBEIRO, H. V.; BARBEIRO, D. F.; TERRABUIO, D. R. B.; ABDALA, E.; SORIANO, F. G.; CARRILHO, F. J.; FARIAS, A. Q.; SIDDIQUI, M. S.; D'ALBUQUERQUE, L. A. C.
    Background. Cardiovascular disease is a major contributing factor to long-term mortality after liver transplantation (LT). Methods. This study evaluated the evolution of atherogenic risk in liver transplant recipients (LTRs). Thirty-six subjects were prospectively enrolled at 12 months and followed for 48 months after liver transplantation. Serum biomarkers of endothelial dysfunction (sICAM-1 and sVCAM-1), chronic inflammation (serum amyloid A), and oxidative stress (myeloperoxidase) were measured at 12 and 48 months after LT. Additionally, at 12 months all patients underwent a cardiac computed tomography (CT) scan and a coronary artery calcium score (CACS). Results. The prevalence of risk factors of metabolic syndrome (MS) increased over the course of the study. The patients' sVCAM-1 and sICAM-1 increased from 1.82 +/- 0.44 ng/mL to 9.10 +/- 5.82 ng/mL (P < .001) and 0.23 +/- 0.09 ng/mL to 2.7 +/- 3.3 ng/mL, respectively from month 12 to 48. Serum myeloperoxidase increased from 0.09 +/- 0.07 ng/mL to 3.46 +/- 3.92 ng/mL (P < .001) over the course of the study. Serum amyloid A also increased from 21.4 +/- 40.7 ng/mL at entry to 91.5 +/- 143.6 ng/mL at end of study (P < .001). Conclusion. No association between these biomarkers and MS was noted. The cardiac CT revealed mild and moderate disease in 19% and 25% of the cohort, respectively. No association between serum biomarkers and CACS was noted. Serum biomarkers of atherogenic risk increase rapidly in LTRs and precede coronary plaques.

    Non-pharmacological management options for MAFLD: a practical guide
    (2023) STEFANO, Jose Tadeu; DUARTE, Sebastiao Mauro Bezerra; ALTIKES, Renato Gama Ribeiro Leite; OLIVEIRA, Claudia P. P.
    Lifestyle changes should be the main basis for any treatment for metabolic dysfunction-associated fatty liver disease (MAFLD), aiming to increase energy expenditure, reduce energy intake and improve the quality of nutrients consumed. As it is a multifactorial disease, approaches such as physical exercise, a better dietary pattern, and possible pharmacological intervention are shown to be more efficient when used simultaneously to the detriment of their applications. The main treatment for MAFLD is a lifestyle change consisting of diet, activity, exercise, and weight loss. The variables for training prescription such as type of physical exercise (aerobic or strength training), the weekly frequency, and the intensity most indicated for the treatment of MAFLD remain uncertain, that is, the recommendations must be adapted to the clinical conditions comorbidities, and preferences of each subject in a way individual. This review addresses recent management options for MAFLD including diet, nutrients, gut microbiota, and physical exercise.

    Pro-atherosclerotic markers and cardiovascular risk factors one year after liver transplantation
    (2014) ALVARES-DA-SILVA, Mario Reis; OLIVEIRA, Claudia Pinto Marques Souza de; STEFANO, Jose Tadeu; BARBEIRO, Hermes V.; BARBEIRO, Denise; SORIANO, Francisco G.; FARIAS, Alberto Queiroz; CARRILHO, Flair Jose; D'ALBUQUERQUE, Luiz Augusto Carneiro
    AIM: To investigate pro-atherosclerotic markers (endothelial dysfunction and inflammation) in patients one year after liver transplantation. METHODS: Forty-four consecutive liver transplant (LT) outpatients who were admitted between August 2009 and July 2010, were followed-up by for 1 year, exhibited no evidences of infection or rejection, all of them underwent tacrolimus-based immunosuppressive regimens were consecutively enrolled. Inflammatory cytokines (TNF alpha, IFN gamma, IL-8, and IL-10), endothelial biomarkers (sVCAM-1, sICAM-1, MPO, adiponectin, PAI-1, SAP, SAA, E-selectin, and MMP-9), high sensitive C-reactive protein, and Framingham risk score (FRS) were assessed. The anthropometric data, aminotransferases, metabolic syndrome features, glucose and lipid profiles, and insulin resistance data were also collected. The LT recipients were compared to 22 biopsy-proven non-alcoholic steatohepatitis (NASH) patients and 20 healthy controls (non-obese, non-diabetics, and non-dyslipidemic). RESULTS: The LT recipients had significantly younger ages and lower body mass indices, aminotransferases, fasting glucose and insulin levels, glucose homeostasis model and metabolic syndrome features than the NASH patients. Classic cardiovascular risk markers, such as Hs-CRP and FRS [2.0 (1.0-8.75)], were lower in the LT patients compared to those observed in the NASH patients (P = 0.009). In contrast, the LT recipients and NASH patients had similar inflammatory and endothelial serum markers compared to the controls (pg/mL): lower IL-10 levels (32.3 and 32.3 vs 62.5, respectively, P = 0.019) and higher IFN gamma (626.1 and 411.9 vs 67.9, respectively, P < 0.001), E-selectin (48.5 and 90.03 vs 35.7, respectively, P < 0.001), sVCAM-1 (1820.6 and 1692.4 vs 1167.2, respectively, P < 0.001), and sICAM-1 (230.3 and 259.7 vs 152.9, respectively, P = 0.015) levels. CONCLUSION: Non-obese LT recipients have similar pro-atherosclerotic serum profiles after a short 1-year follow-up period compared to NASH patients, suggesting a high risk of atherosclerosis in this population.

    Physical training improves body weight and energy balance but does not protect against hepatic steatosis in obese mice
    (2015) EVANGELISTA, Fabiana S.; MULLER, Cynthia R.; STEFANO, Jose T.; TORRES, Mariana M.; MUNTANELLI, Bruna R.; SIMON, Daniel; ALVARES-DA-SILVA, Mario R.; PEREIRA, Isabel V.; COGLIATI, Bruno; CARRILHO, Flair J.; OLIVEIRA, Claudia P.
    This study sought to determine the role of physical training (PT) on body weight (BW), energy balance, histological markers of nonalcoholic fatty liver disease (NAFLD) and metabolic gene expression in the liver of ob/ob mice. Adult male ob/ob mice were assigned into groups sedentary (S; n = 8) and trained (T; n = 9). PT consisted in running sessions of 60 min at 60% of maximal speed conducted five days per week for eight weeks. BW of S group was higher from the 4th to 8th week of PT compared to their own BW at the beginning of the experiment. PT decreased daily food intake and increased resting oxygen consumption and energy expenditure in T group. No difference was observed in respiratory exchange ratio, but the rates of carbohydrate and lipids oxidation, and maximal running capacity were greater in T than S group. Both groups showed liver steatosis but not inflammation. PT increased CPT1a and SREBP1c mRNA expression in T group, but did not change MTP, PPAR-alpha, PPAR-gamma, and NFKB mRNA expression. In conclusion, PT prevented body weight gain in ob/ob mice by inducing negative energy balance and increased physical exercise tolerance. However, PT did not change inflammatory gene expression and failed to prevent liver steatosis possible due to an upregulation in the expression of SREBP1c transcription factor. These findings reveal that PT has positive effect on body weight control but not in the liver steatosis in a leptin deficiency condition.

    Association between Metabolic Disorders and Cholangiocarcinoma: Impact of a Postulated Risk Factor with Rising Incidence
    (2022) FONSECA, Leonardo G. Da; HASHIZUME, Pedro H.; OLIVEIRA, Irai Santana de; IZQUIERDO-SANCHEZ, Laura; SAUD, Lisa Rodrigues da Cunha; XERFAN, Mariana Pinheiro; ALVES, Venancio Avancini Ferreira; MELLO, Evandro Sobroza de; HERMAN, Paulo; BANALES, Jesus M.; OLIVEIRA, Claudia P.; CARRILHO, Flair J.
    Simple Summary A potential relationship between cholangiocarcinoma and metabolic disorders has been suggested, but there is a lack of published data. This study aimed to describe the prevalence of metabolic disorders in a cohort of 122 patients with cholangiocarcinoma and report clinical outcomes. We found a prevalence of 42.6% of metabolic disorders. There was no significant difference in overall survival between patients with or without metabolic disorders, although there was a better survival in the subgroup of patients undergoing surgical resection. This indicates a need to better explore the association between cholangiocarcinoma in a metabolic background. Introduction and objectives: The incidence of cholangiocarcinoma (CCA) has been increasing globally. Although a concomitant increase in the incidence of metabolic disorders might suggest a causal relationship, the data are scarce. We aimed to describe the prevalence of metabolic disorders in patients with CCA and report the clinical features and outcomes. Patients and Methods: Retrospective study including patients with CCA. Patients were divided into: (1) past history of diabetes or/and overweight/obesity (""metabolic disorder group"") and (2) without any of these features (""non-metabolic-disorder group""). A Cox regression model was used to determine the prognostic factors. Results: 122 patients were included. In total, 36 (29.5%) had overweight/obesity, 24 (19.7%) had diabetes, and 8 (6.6%) had both. A total of 29 (23.8%) patients had resectable disease and received upfront surgery. A total of 104 (85.2%) received chemotherapy for advanced/recurrent disease. The overall survival of the cohort was 14.3 months (95% CI: 10.1-17.3). ECOG-PS 0 (p < 0.0001), resectable disease (p = 0.018) and absence of vascular invasion (p = 0.048) were independently associated with better prognosis. The ""metabolic disorder group"" (n = 52) had a median survival of 15.5 months (95% CI 10.9-33.9) vs. 11.5 months (95% CI 8.4-16.5) in the ""non-metabolic-disorder group"" (n = 70) (HR: 1.10; 95% CI 0.62-1.94). Patients with resectable disease in the ""metabolic group"" had longer survival than patients in the ""non-metabolic group"" (43.4 months (95% CI 33.9-NR) vs. 21.8 months (95% CI 8.6-26.9); HR = 0.12, 95% CI 0.03-0.59). Conclusion: Metabolic disorders are frequent among CCA patients. Underlying metabolic comorbidities may be associated with prognosis in resectable CCA. There is a need to explore the mechanism that drives CCA carcinogenesis in a metabolic background.
