- Translational medical research and liver transplantation: systematic review(2018) NACIF, Lucas Souto; KIM, Vera; GALVAO, Flavio; ONO, Suzane Kioko; PINHEIRO, Rafael Soares; CARRILHO, Flair Jose; D'ALBUQUERQUE, Luiz CarneiroTranslational medicine has become a priority, but there is still a big difference between the arrival of new treatments and investment. Basic science should not be neglected because the translation from basic research is not sustained in the absence of basic research. The purpose of this literature review was to analyze the translational medicine in the liver transplant field: liver ischemia-reperfusion injury (IRI), immunosuppression, clinical and surgical complications, small-for-size syndrome (SFSS), rejection, and ongoing innovations (liver machine, liver preservation, artificial livers, and regenerative medicine). We performed a systematic literature review that were updated in October 2016. The searches were performed in the Cochrane Central Register of Controlled Trials and Review, PubMed/Medline, Embase, and LILACS databases. All the selected studies on the management of translational medical research in liver transplantation (LT) were analyzed. Initially the search found 773 articles. Methodological viewing and analysis of the articles, followed by the application of scientific models, including translational medicine in the liver transplant field. In conclusions, this review demonstrates the application of scientific research with translation medical benefits regarding the LT. The literature has a great tendency, improvements and investments in the study of translational medicine in LT. Innovative studies and technologies from basic science help to clarify clinical doubts. Moreover, evidence increases the importance of scientific research in quality of clinical practice care.
- Epidemiology of Liver Cancer in Latin America: Current and Future Trends(2020) CARRILHO, Flair Jose; PARANAGUA-VEZOZZO, Denise Cerqueira; CHAGAS, Aline Lopes; ALENCAR, Regiane Saraiva de Souza Melo; FONSECA, Leonardo Gomes daOver 38,000 cases of hepatocellular carcinoma (HCC) are estimated to occur in Latin America annually. The region is characterized by sociocultural heterogeneity and economic disparities, which impose barriers in addressing this major health issue. A significant proportion of patients are still diagnosed in the later stages of the disease, although efforts to implement effective screening programs have been reported by referral centers. While viral hepatitis remains the predominant etiology of liver disease among HCC cases in Latin America, a high prevalence of fatty liver disease in the region is a matter of concern, reflecting the current scenario in many Western countries. In addition, other risk factors such as alcohol, aflatoxin, and early-onset HCC in hepatitis B virus infection contribute to the burden of HCC in Latin America. Interventions to increase screening coverage, expand healthcare access, and implement continuing medical training are key challenges to be overcome.
- Pegylated interferon alfa for chronic hepatitis B: systematic review and meta-analysis(2016) KIM, V.; ABREU, R. M.; NAKAGAWA, D. M.; BALDASSARE, R. M.; CARRILHO, F. J.; ONO, S. K.Conventional interferon alfa and nucleos(t)ide analogues, such as lamivudine, are frequently used for chronic hepatitis B (CHB) treatment, but are associated with adverse effects and viral resistance. Here we performed a systematic review and meta-analysis evaluating all studies of pegylated interferon alfa (PEG-IFN) treatment in hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients with CHB. We searched electronic databases - PubMed, EMBASE, Cochrane Library and LILACS - for randomized controlled trials evaluating PEG-IFN therapy between 1999 and September 2014. Virological response was the primary outcome. We identified 14 studies involving 2829 patients. Our analysis revealed that PEG-IFN+lamivudine combination therapy produced better virological and biochemical responses than PEG-IFN monotherapy in HBeAg-positive and HBeAg-negative patients at the end of treatment. PEG-IFN+adefovir dipivoxil achieved better seroconversion rate than PEG-IFN in HBeAg-positive patients at the end of treatment. The present findings demonstrated a beneficial response rate following PEG-IFN combination therapy with nucelos(t)ides among HBeAg-positive and HBeAg-negative patients with CHB. Further trials are needed to investigate simultaneous and sequential therapy strategies.
- Clinical and epidemiological aspects of hepatocellular carcinoma in Brazil(2013) KIKUCHI, Luciana; CHAGAS, Aline L.; ALENCAR, Regiane S. S. M.; PARANAGUA-VEZOZZO, Denise C.; CARRILHO, Flair J.The global hepatocellular carcinoma (HCC) incidence is widely variable, depending on geographic region and the prevalence of major risk factors. In Brazil, two large multicentre retrospective studies were performed to investigate clinical and epidemiological aspects of HCC. In the first study, performed in 1997, HCC was found in cirrhotic livers in 71% of cases. Chronic alcoholism was present in 36% of cases, chronic hepatitis B in 35% and hepatitis C in 25%. In a 2010 survey, cirrhosis was present in 98% of cases and HCV was the main aetiology (54%). Differences in HBV prevalence were found among regions. Selection of HCC treatment depends on tumour burden, liver function and performance status. Liver transplantation ( LT) is the best available curative treatment for HCC in its early stage and with compromised liver function. After modifications in priority policy, the number of patients with early HCC submitted for LT has increased in the past 5 years in Brazil. Chemoembolization is the most common initial HCC therapy in early and intermediate stages of HCC in Brazil.
- Terlipressin versus Norepinephrine in the Treatment of Hepatorenal Syndrome: A Systematic Review and Meta-Analysis(2014) NASSAR JUNIOR, Antonio Paulo; FARIAS, Alberto Queiroz; ALBUQUERQUE, Luiz Augusto Carneiro d'; CARRILHO, Flair Jose; MALBOUISSON, Luiz Marcelo SaBackground: Hepatorenal syndrome (HRS) is a severe and progressive functional renal failure occurring in patients with cirrhosis and ascites. Terlipressin is recognized as an effective treatment of HRS, but it is expensive and not widely available. Norepinephrine could be an effective alternative. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of norepinephrine compared to terlipressin in the management of HRS. Methods: We searched the Medline, Embase, Scopus, CENTRAL, Lilacs and Scielo databases for randomized trials of norepinephrine and terlipressin in the treatment of HRS up to January 2014. Two reviewers collected data and assessed the outcomes and risk of bias. The primary outcome was the reversal of HRS. Secondary outcomes were mortality, recurrence of HRS and adverse events. Results: Four studies comprising 154 patients were included. All trials were considered to be at overall high risk of bias. There was no difference in the reversal of HRS (RR = 0.97, 95% CI = 0.76 to 1.23), mortality at 30 days (RR = 0.89, 95% CI = 0.68 to 1.17) and recurrence of HRS (RR = 0.72; 95% CI = 0.36 to 1.45) between norepinephrine and terlipressin. Adverse events were less common with norepinephrine (RR = 0.36, 95% CI = 0.15 to 0.83). Conclusions: Norepinephrine seems to be an attractive alternative to terlipressin in the treatment of HRS and is associated with less adverse events. However, these findings are based on data extracted from only four small studies.
- Hepatocellular Carcinoma Related to Schistosoma mansoni Infection: Case Series and Literature Review(2015) TODA, Karla Sawada; KIKUCHI, Luciana; CHAGAS, Aline Lopes; TANIGAWA, Ryan Yukimatsu; PARANAGUA-VEZOZZO, Denise Cerqueira; PFIFFER, Tulio; ROCHA, Manoel de Souza; ALVES, Venancio Avancini Ferreira; CARRILHO, Flair JoseBackground and Aims: Schistosomiasis is a major chronic disease of humans in endemic regions, and infected individuals may develop a spectrumof pathology, including hepatic fibrosis, hepatosplenomegaly, and portal hypertension. Hepatocellular carcinoma (HCC) is considered the fifth most common cancer in the world, and there is limited and controversial evidence suggesting that Schistosoma mansoni infection may be a possible risk factor for HCC. The aim of this study was to report a case series of patients with HCC and S. mansoni infection and to conduct a literature review on the topic. Methods: From January 2002 to January 2015, an institutional database was screened retrospectively to identify patients with HCC and S. mansoni infection at a single center in the Department of Gastroenterology of University of Sao Paulo School of Medicine and Hospital das Clinicas, Brazil. Results: Seven cases were included. The mean age of patients was 62.1 +/- 10.3 years; six (85.7%) were male and one (14.3%) was female. All cases had positive epidemiology, coming from endemic areas of S. mansoni infection in Brazil, and four (57.1%) had previous complications (upper gastrointestinal bleeding) related toportal hypertension or surgery intervention (splenectomy) performed more than 10 years before the HCC diagnosis. Nontumoral portal vein thrombosis was identified in five (71.4%) patients. All patients had negative serology for HCV, and four (57.1%) had positivity of HBVcore antibodies without evidence of viral replication. According to BCLC staging, one (14.3%) patient was BCLC A and received TACE instead of RFA because HCC size was >30 mm; three (42.8%) BCLC B patients received sorafenib instead of local regional treatment due to the presence of nontumoral TPV. During follow-up, all patients developed tumoral progression and died. Conclusions: It remains unclear if S. mansoni infection alone has carcinogenic potential. The available literature indicates that S. Mansoni, in the presence of HBV and HCV infections, likely acts as a cofactor for the hepatic lesion and potentiates injury.
- Nonalcoholic Fatty Liver Disease and Hepatocellular Carcinoma(2014) KIKUCHI, Luciana; OLIVEIRA, Claudia P.; CARRILHO, Flair J.Hepatocellular carcinoma (HCC) incidence is increasing worldwide in recent years. Most HCC cases develop in the presence of advanced chronic liver disease related to chronic hepatitis C virus (HCV) infection, chronic hepatitis B (HBV) infection, and alcohol abuse. Approximately 15-50% of HCC cases are classified as idiopathic, suggesting that other risk factors are responsible for its rising incidence. Recent studies suggest that nonalcoholic fatty liver disease (NAFLD) can be associated with these ""idiopathic"" cases. NAFLD progresses slowly and can develop into liver cirrhosis, liver failure, and HCC. In the last few years, NAFLD has received more attention because of its high prevalence worldwide.
- IMPACT OF CURRENT DIET AT THE RISK OF NON-ALCOHOLIC FATTY LIVER DISEASE (NAFLD)(2019) DUARTE, Sebastião Mauro Bezerra; STEFANO, José Tadeu; VANNI, Denise Siqueira; CARRILHO, Flair José; OLIVEIRA, Claudia Pinto Marques Souza deABSTRACT The nonalcoholic fatty liver disease (NAFLD) affects approximately 20%-30% of general population and is even more prevalent among obese individuals. The risk factors mainly associated with NAFLD are diseases related to the metabolic syndrome, genetics and environment. In this review, we provide a literature compilation evaluating the evidence behind dietary components, including calories intake, fat, protein, fibers and carbohydrate, especially fructose which could be a trigger to development and progression of the NAFLD. In fact, it has been demonstrated that diet is an important factor for the development of NAFLD and its association is complex and extends beyond total energy intake.
- Portal vein surgical treatment on non-tumoral portal vein thrombosis in liver transplantation: Systematic Review and Meta-Analysis(2021) NACIF, Lucas S.; ZANINI, Leonardo Y.; PINHEIRO, Rafael S.; WAISBERG, Daniel R.; ROCHA-SANTOS, Vinicius; ANDRAUS, Wellington; CARRILHO, Flair J.; CARNEIRO-D'ALBUQUERQUE, LuizNon-tumoral portal vein thrombosis (PVT) is associated with higher morbidity and mortality in liver transplantation (LT). In this study, we aimed to evaluate the impact of PVT in LT outcomes and analyze the types of surgical techniques used for dealing with PVT during LT. A systematic review was conducted in Cochrane, MEDLINE, and EMBASE databases, selecting articles from January 1990 to December 2019. The MESH-terms used were (""Portal Vein""[Mesh] AND ""Thrombosis""[Mesh] NOT ""Neoplasms""[Mesh]) AND (""Liver Transplantation""[Mesh]). The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) recommendation was used, and meta-analysis was performed with Review Manager Version 5.3 software. A total of 1,638 articles were initially found: 488 in PubMed, 289 in Cochrane Library, and 861 in EMBASE, from which 27 were eventually selected for the meta-analysis. Surgery time of LT in patients with PVT was longer than in patients without LT (p<0.0001). Intraoperative red blood cell (p<0.00001), fresh frozen plasma (p=0.01), and platelets (p=0.03) transfusions during LT were higher in patients with PVT. One-year (odds ratio [OR] 1.17; p=0.002) and 5-year (OR 1.12; p=0.01) patient survival after LT was worse in the PVT group. Total occlusive PVT presented higher mortality (OR 3.70; p=0.00009) and rethrombosis rates (OR 3.47 [1.18-10.21]; p=0.02). PVT Yerdel III/IV classification exhibited worse 1-year [2.04 (1.21-3.42); p=0.007] and 5-year [0.98 (0.59-1.62); p=0.93] patient survival. Thrombectomy with primary anastomosis was associated with better outcomes. LT in patients with non-tumoral PVT demands more surgical time, needs more intraoperative transfusion, and presents worse 1- and 5-year patient survival. Total occlusive PVT and Yerdel III/IV PVT classification were associated with higher mortality.
- Genetic Risk for Alcoholic Chronic Pancreatitis(2011) COSTA, Marianges Zadrozny Gouvea da; GUARITA, Dulce Reis; ONO-NITA, Suzane Kioko; PARANAGUA-VEZOZZO, Denise Cerqueira; FELGA, Guilherme Eduardo Goncalves; PEDROSO, Martha Regina Arcon; SOUZA, Marcelo Moreira Tavares de; NASSER, Paulo Dominguez; FERREIRA, Camila da Silva; CARRILHO, Flair JoseIn recent years many studies have examined the genetic predisposition to pancreatic diseases. Pancreatic disease of an alcoholic etiology was determined to be a multi-factorial disease, where environmental factors interact with the genetic profile of the individual. In this review we discuss the main results from studies examining the frequency of genetic mutations in alcoholic chronic pancreatitis.
