- 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.
article 2 Citação(ões) na Scopus m-RECIST at 1 month and Child A are survival predictors after percutaneous ethanol injection of hepatocellular carcinoma(2014) SILVA, Mauricio F.; CARRILHO, Flair J.; PARANAGUA-VEZOZZO, Denise C.; CAMPOS, Luciana T.; NACIF, Lucas S.; DINIZ, Marcio A.; FARIAS, Alberto Q.; ALVES, Venancio A. F.; D'ALBURQUERQUE, Luis A. C.; ONO, Suzane K.Background and aims. Percutaneous ethanol injection (PEI) is a well-established therapeutic option in patients with cirrhosis and hepatocellular carcinoma (HCC). The modified-Response Evaluation Criteria in Solid Tumors (m-RECIST) are an important tool for the assessment of HCC response to therapy. The aim was to evaluate whether HCC response according to the m-RECIST criteria could be an effective predictor of Long-term survival in Barcelona Clinic Liver Cancer (BCLC) stage 0 and A HCC patients undergoing PEI. Material and methods. 79 patients were followed-up for median time of 26.8 months. HCC diagnosis was based on the,current guidelines of the American Association for Study of the Liver Diseases (AASLD) and European Association for Study of the Liver (EASL). Patient survival was calculated from the first PEI session to the end of the follow-up. Results. The 1-, 3-, and 5-year overall survival rates were 79, 48 and 37%, respectively. In the multivariate analysis, Child-Pugh-Turcotte (CPT) (p = 0.022) and the response to m-RECIST criteria (p = 0.016) were associated with patient survival. CPT A patients who achieved Complete Response (CR) 1 month after PEI presented a 5-year survival rate of 55%. By contrast, the worst scenario, the group with CPT B but without CR had a 5-year survival rate of 9%, while the group with either CPT A or CR as a survival predictor had a 5-year survival rate of 31%. In conclusion, in BCLC stage 0 and A HCC-patients, m-RECIST at 1 month and Child A may predict survival rates after PEI.- Excessive daytime sleepiness, but not sleep apnea, sleep duration or insomnia, was associated with poor adherence to anti-hypertensive treatment: The ELSA-Brasil study(2023) AIELO, Aline N.; SANTOS, Ronaldo B.; GIATTI, Soraya; SILVA, Wagner A.; PARISE, Barbara K.; CUNHA, Lorenna F.; SOUZA, Silvana P.; LOTUFO, Paulo A.; BENSENOR, Isabela M.; DRAGER, Luciano F.Hypertension is the leading risk factor for cardiovascular mortality. Poor adherence may partially explain this scenario. Beyond traditional factors, it is conceivable that sleep conditions such as Obstructive Sleep Apnea (OSA), Sleep Duration (SDUR), sleepiness and insomnia may contribute to impair adherence but the evidence is scanty. Consecutive participants with hypertension from the ELSA-Brasil study performed a home sleep monitoring and 7-days actigraphy to determine OSA (apnea-hypopnea index >= 15 events/ hour) and SDUR, respectively. Excessive daytime sleepiness (EDS) and insomnia were evaluated by Epworth Sleepiness Scale (ESS) and Clinical Interview Scheduled Revised (CIS-R), respectively. The 4itens Morisky questionnaire was used to evaluate adherence to anti-hypertensive therapy. A total of 411 patients were including in the analysis (mean age: 54 +/- 8 years, 47% men). Medium/low adherence to anti-hypertensive therapy was observed in 62%. Compared to the high adherence group, the participants with medium/low adherence had lower frequencies of Whites (64.1 vs. 47.8%), high-degree education (50.6 vs. 40%), and monthly per-capita income ($1021.90 vs. $805.20). In contrast, we observed higher frequency of EDS (35.9 vs. 46.1%). No differences were observed for OSA, short SDUR (<6 h) and insomnia. Logistic regression analysis showed that race other than White (OR: 1.80; 95% IC:1.15-2.82), lower monthly income (OR: 1.74; 95% IC:1.01-3.0) and EDS (OR: 1.63; 95% IC:1.05-2.53) were independently associated with medium/low adherence to the anti-hypertensive treatment. Interestingly, EDS mediated the abdominal obesity-adherence outcome. In conclusion, among sleep-related parameters, EDS, but not OSA, short SDUR or insomnia, were associated to impaired adherence to anti-hypertensive therapy.(c) 2023 Elsevier B.V. All rights reserved.
- Accuracy of transient elastography-FibroScan (R), acoustic radiation force impulse (ARFI) imaging, the enhanced liver fibrosis (ELF) test, APRI, and the FIB-4 index compared with liver biopsy in patients with chronic hepatitis C(2017) RAGAZZO, Taisa Grotta; PARANAGUA-VEZOZZO, Denise; LIMA, Fabiana Roberto; MAZO, Daniel Ferraz de Campos; PESSOA, Mario Guimaraes; OLIVEIRA, Claudia Pinto; ALVES, Venancio Avancini Ferreira; CARRILHO, Flair JoseOBJECTIVES: Although liver biopsy is the gold standard for determining the degree of liver fibrosis, issues regarding its invasiveness and the small amount of liver tissue evaluated can limit its applicability and interpretation in clinical practice. Non-invasive evaluation methods for liver fibrosis can address some of these limitations. The aim of this study was to evaluate the accuracy of transient elastography-FibroScan (R), acoustic radiation force impulse (ARFI), enhanced liver fibrosis (ELF), the aspartate aminotransferase-to-platelet ratio index (APRI), and the FIB-4 index compared with liver biopsy in hepatitis C. METHODS: We evaluated chronic hepatitis C patients who were followed at the Division of Clinical Gastroenterology and Hepatology, Hospital das Clinicas, Department of Gastroenterology of University of Sao Paulo School of Medicine, Sao Paulo, Brazil, and who underwent liver biopsy. The accuracy of each method was determined by a receiver operating characteristic (ROC) curve analysis, and fibrosis was classified as significant fibrosis (>= F2), advanced fibrosis (>= F3), or cirrhosis (F4). The Obuchowski method was also used to determine the diagnostic accuracy of each method at the various stages of fibrosis. In total, 107 FibroScan (R), 51 ARFI, 68 ELF, 106 APRI, and 106 FIB-4 analyses were performed. RESULTS: A total of 107 patients were included in the study. The areas under the ROC curve (AUROCs) according to fibrosis degree were as follows: significant fibrosis (>= F2): FibroScan (R) : 0.83, FIB-4: 0.76, ELF: 0.70, APRI: 0.69, and ARFI: 0.67; advanced fibrosis (>= F3): FibroScan (R) : 0.85, ELF: 0.82, FIB-4: 0.77, ARFI: 0.74, and APRI: 0.71; and cirrhosis (F4): APRI: 1, FIB-4: 1, FibroScan (R) : 0.99, ARFI: 0.96, and ELF: 0.94. The accuracies of transient elastography, ARFI, ELF, APRI and FIB-4 determined by the Obuchowski method were F0-F1: 0.81, 0.78, 0.44, 0.72 and 0.67, respectively; F1-F2: 0.73, 0.53, 0.62, 0.60, and 0.68, respectively; F2-F3: 0.70, 0.64, 0.77, 0.60, and 0.67, respectively; and F3-F4: 0.98, 0.96, 0.82, 1, and 1, respectively. CONCLUSION: Transient elastography remained the most effective method for evaluating all degrees of fibrosis. The accuracy of all methodologies was best at F4.
- Strong correlation by ultrasonography of hepatomegaly and the presence of co-infection in HIV/HCV cirrhotic patients(2013) VEZOZZO, Denise Cerqueira Paranagua; MENDES-CORREA, Maria Cassia; CUNHA-SILVA, Marlone; ALVARADO-MORA, Monica Viviana; FRANCA, Joao Italo Dias; SEBBA, Jose Luiz; NICODEMO, Antonio Carlos; OLIVEIRA, Claudia P. M. S.; CARRILHO, Flair JoseObjectives: Progression of hepatic fibrosis is accelerated in patients co-infected with human immunodeficiency virus and hepatitis C virus compared to hepatitis C virus mono-infected patients. This study aimed to compare ultrasound features and selected clinical and biochemical variables between patients with human immunodeficiency virus/hepatitis C virus co-infection (n = 16) versus hepatitis C virus mono-infection (n = 16). Methods: Each patient underwent abdominal ultrasound, and a specific evaluation was performed in order to detect findings consistent with chronic liver disease. Characterization of spleen size, liver structural pattern, diameter of the portal, spleen, and mesenteric veins was based on classical ultrasound parameters. Propensity score was used for control of selection bias and performed using binary logistic regression to generate a score for each patient. The Fisher and Mann-Whitney tests were used to evaluate categorical variables and continuous variables, respectively. Results: On univariate analysis right hepatic lobe size was larger in human immunodeficiency virus/hepatitis C virus patients (157.06 +/- 17.56 mm) compared to hepatitis C virus mono-infected patients (134.94 +/- 16.95 mm) (p = 0.0011). The left hepatic lobe was also significantly larger in human immunodeficiency virus/hepatitis C virus patients (115.88 +/- 22.69 mm) versus hepatitis C virus mono-infected patients (95.06 +/- 24.18 mm) (p = 0.0177). Also, there was a strong correlation between hepatomegaly and co-infection (p = 0.005). Conclusion: Human immunodeficiency virus infection was the primary variable influencing liver enlargement in this population. Hepatomegaly on ultrasound was more common among cirrhotic human immunodeficiency virus/hepatitis C virus co-infected patients than among cirrhotic hepatitis C virus mono-infected patients. This aspect is very important in the management of human immunodeficiency virus/hepatitis C virus co-infected patients, because screening for hepatocellular carcinoma is necessary in this population.
