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.conferenceObject Evaluation of the Small Intestine by Video Capsule Endoscopy in Patients Candidates for Liver Transplantation(2012) FYLYK, Sonia N.; TOBARU, Andre; MESTIERI, Luiz H.; FARIAS, Alberto Q.; CARRILHO, Flair J.; D'ALBUQUERQUE, Luiz Augusto C.; MOURA, Eduardo G. De; SAKAI, PauloIntroduction: Recent studies suggest that in cirrhotic patients the small intestine can be affected by the consequences of a system of portal hypertension (PTH). This segment of the gastrointestinal tract, however, is hardly accessible for study. The video capsule endoscopy (VCE) is considered the gold standard exam for the investigation of small bowel diseases, especially vascular diseases of the intestinal mucosa. Objective: Evaluation of the findings of PTH in the mucosa of the small bowel of cirrhotic patients, candidates for liver transplantation (LT). Patients and Methods: Prospective, single-center, controlled study. All patients signed informed consent and the study was approved by the ethics committee. 21 patients were submitted to VCE and esophagogastroduodenoscopy (14 patients with liver cirrhosis candidates to LT and 7 control cases, with normal liver function and no evidence of PTH). Inclusion criteria: - Patients with liver cirrhosis of viral and/or alcoholic etiology and with indication for LT (Child-Pugh score A, B or C and MELD < 20). Patients submitted or not to endoscopic treatment of esophagogastric varices or GAVE. - Patients over 18 years. - Patients who agree to participate in the study. Exclusion criteria: - Patients with history of abdominal surgery and intestinal transit abnormalities. - Intestinal sub-occlusion or suspected gastroparesis. - Patients with congestive heart disease. - Patients with potentially hemorrhagic lesions that can contribute to anemia (ulcers, polyps) and not related to PTH. Results: The mucosal lesions of the small intestine secondary to portal hypertension were more common in cirrhotic patients than in control patients: 13/14 (92.8%) vs. 1/7 (14.2%). The reticular pattern of the mucosa (hypertensive enteropathy) was the most important finding of the cases (10/14 -71.4%), followed by vascular ectasia-like and varices of the jejunum and ileum (7/14 - 50%). Conclusion: This group of patients has significant changes in the mucosa of the small intestine secondary to PTH and this segment of the gastrointestinal tract may represent a site of bleeding, often classified as obscure. The VCE is an important tool for the identification of these lesions, contributing to a more accurate etiologic diagnosis.- Serum B-type natriuretic peptide in the initial workup of patients with new onset ascites: A diagnostic accuracy study (vol 59, pg 1043. 2014)(2014) FARIAS, Alberto Q.; SILVESTRE, Odilson M.; GARCIA-TSAO, Guadalupe; SEGURO, Luis F.

- Preservation of thrombin generation in cirrhosis despite abnormal results of international normalized ratio: implications for invasive procedures(2021) FERREIRA, Caroline M.; ROCHA, Tania R. F.; SOUZA, Evandro O.; CARRILHO, Flair J.; D'AMICO, Elbio A.; FARIAS, Alberto Q.Thrombin generation is normal or elevated in patients with cirrhosis when tested in the presence of thrombomodulin, the activator of the main natural anticoagulant protein C. However, the relationship between thrombin generation with bleeding has been little explored in literature. 97 Consecutive patients with cirrhosis were prospectively included (58 men; 54 +/- 10 years) and divided into two groups international normalized ratio (INR) less than 1.5 (n = 72) or INR at least 1.5 (n = 25). 46 Healthy individuals were tested as controls. Endogenous thrombin potential (ETP) was measured without and with the addition of thrombomodulin. ETP measured without thrombomodulin was reduced in patients with cirrhosis when compared with controls, but no significant difference was found between the INR less than 1.5 and INR at least 1.5 groups (1250 +/- 315.7 versus 1186 +/- 238 nmol/l x min; P = 0.3572). After the addition of thrombomodulin, both groups generated thrombin comparable with controls (INR >= 1.5: 965.9 +/- 232.3; INR < 1.5: 893.0 +/- 368.6; controls: 915.0 +/- 458 nmol/l x min). 80% of patients had high ETP without/with thrombomodulin ratio, demonstrating the resistance to the anticoagulant action of thrombomodulin for both groups. This was more marked in the INR at least 1.5 group (0.81 +/- 0.1 versus 0.69 +/- 0.2; P = 0.0042). Postligation of esophageal varices bleeding occurred in 5.2% of patients (INR < 1.5, n = 3; INR >= 1.5, n = 2), all of them with ETP without/with thrombomodulin ratio ranging from 0.72 to 0.90 (controls 0.57 +/- 0.21). This study confirms that thrombin generation in the presence of thrombomodulin was normal in most patients with cirrhosis, including those with high INR value, but did not correlate with postligation of esophageal varices bleeding.
- HIGHER VALUES IN LIVER ELASTOGRAPHY AND MELD SCORE ARE MORTALITY PREDICTORS ON LIVER TRANSPLANT WAITING LIST(2018) NACIF, Lucas Souto; PARANAGUA-VEZOZZO, Denise C.; MATSUDA, Alina; ALVES, Venancio Avancini Ferreira; CARRILHO, Flair J.; FARIAS, Alberto Queiroz; D'ALBUQUERQUE, Luiz Carneiro; ANDRAUS, WellingtonBackground: Liver elastography have been reported in hepatocellular carcinoma (HCC) with higher values; however, it is unclear to identify morbimortality risk on liver transplantation waiting list. Aim: To assess liver stiffness, ultrasound and clinical findings in cirrhotic patients with and without HCC on screening for liver transplant and compare the morbimortality risk with elastography and MELD score. Method: Patients with cirrhosis and HCC on screening for liver transplant were enrolled with clinical, radiological and laboratory assessments, and transient elastography. Results: 103 patients were included (without HCC n=58 (66%); HCC n=45 (44%). The mean MELD score was 14.7 +/- 6.4, the portal hypertension present on 83.9% and the mean transient elastography value was 32.73 +/- 22.5 kPa. The median acoustic radiation force impulse value of liver parenchyma was 1.98 (0.65-3.2) m/s and 2.16 (0.59-2.8) m/s in HCC group. The HCC group was significantly associated with HCV infection (OR 26.84; p<0.0001), higher levels of serum alpha-fetoprotein (OR 5.51; p=0.015), clinical portal hypertension (OR 0.25; p=0.032) and similar MELD score (p=0.693). The area under the receiver operating characteristics (AUROC) showed sensitivity and specificity for serum alpha-fetoprotein (cutoff 9.1 ng/ml), transient elastography value (cutoff value 9 kPa), and acoustic radiation force impulse value (cutoff value 2.56 m/s) of 50% and 86%, 92% and 17% and 21% and 92%, respectively. The survival group had a mean transient elastography value of 31.65 +/- 22.2 kPa vs. 50.87 +/- 20.9 kPa (p=0.098) and higher MELD scores (p=0.035). Conclusion: Elastography, ultrasound and clinical findings are important non-invasive tools for cirrhosis and HCC on screening for liver transplant. Higher values in liver elastography and MELD scores predict mortality.
- Alcohol-Related Liver Disease Is Rarely Detected at Early Stages Compared With Liver Diseases of Other Etiologies Worldwide(2019) SHAH, Neil D.; VENTURA-COTS, Meritxell; ABRALDES, Juan G.; ALBORAIE, Mohamed; ALFADHLI, Ahmad; ARGEMI, Josepmaria; BADIA-ARANDA, Ester; ARUS-SOLER, Enrique; BARRITT, A.

We investigated whether patients with ALD are initially seen at later stages of disease development than patients with hepatitis C virus (HCV) infection or other etiologies. METHODS: We performed a cross-sectional study of 3453 consecutive patients with either early or advanced liver disease (1699 patients with early and 1754 with advanced liver disease) seen at 17 tertiary care liver or gastrointestinal units worldwide, from August 2015 through March 2017. We collected anthropometric, etiology, and clinical information, as well as and model for end-stage liver disease scores. We used unconditional logistic regression to estimate the odds ratios for evaluation at late stages of the disease progression. RESULTS: Of the patients analyzed, 81% had 1 etiology of liver disease and 17% had 2 etiologies of liver disease. Of patients seen at early stages for a single etiology, 31% had HCV infection, 21% had hepatitis B virus infection, and 17% had nonalcoholic fatty liver disease, whereas only 3.8% had ALD. In contrast, 29% of patients seen for advanced disease had ALD. Patients with ALD were more likely to be seen at specialized centers, with advanced-stage disease, compared with patients with HCV-associated liver disease (odds ratio, 14.1; 95% CI, 10.5-18.9; P < .001). Of patients with 2 etiologies of liver disease, excess alcohol use was associated with 50% of cases. These patients had significantly more visits to health care providers, with more advanced disease, compared with patients without excess alcohol use. The mean model for end-stage liver disease score for patients with advanced ALD (score, 16) was higher than for patients with advanced liver disease not associated with excess alcohol use (score, 13) (P < .01). CONCLUSIONS: In a cross-sectional analysis of patients with liver disease worldwide, we found that patients with ALD are seen with more advanced-stage disease than patients with HCV-associated liver disease. Of patients with 2 etiologies of liver disease, excess alcohol use was associated with 50% of cases. Early detection and referral programs are needed for patients with ALD worldwide.
- beta-Blocker therapy for cirrhotic cardiomyopathy: a randomized-controlled trial(2018) SILVESTRE, Odilson M.; FARIAS, Alberto Q.; RAMOS, Danusa S.; FURTADO, Meive S.; RODRIGUES, Ana C.; XIMENES, Rafael O.; MAZO, Daniel F. de Campos; ZITELLI, Patricia M. Yoshimura; DINIZ, Marcio A.; ANDRADE, Jose L.; STRUNZ, Celia; FRIEDMANN, Antonio A.; LEE, Samuel S.; CARRILHO, Flair J.; D'ALBUQUERQUE, Luiz A. C.; BACAL, FernandoBackground Cirrhotic cardiomyopathy is characterized by an attenuated contractile response to stress. Long-term exposure of beta-adrenergic receptors to persistently high levels of catecholamines has been implicated in its pathogenesis. We hypothesized that beta-blockade with metoprolol could reverse the changes in heart function and morphology in cirrhotic cardiomyopathy. Patients and methods In this prospective randomized trial, we included 78 patients aged between 18 and 60 years with abnormal cardiac output response under dobutamine stress echocardiography, without primary cardiac disease or a history of alcohol intake. Patients were assigned randomly to receive metoprolol or placebo for 6 months. The primary endpoint was the improvement in cardiac output response to stress, measured by an increase in the left ventricle stroke volume more than 30%. Results Three (7.3%) patients in the metoprolol group and nine (24.3%) patients in the placebo group showed improved stroke volume (P=0.057). Diastolic dysfunction was found in two (4.8%) patients before and in five (15.6%) patients after therapy in the metoprolol group, and in 10 (27%) patients before and nine (31%) patients after therapy in the placebo group (P=0.67). After treatment, no echocardiography parameter of morphology was significantly different between metoprolol or placebo groups. No significant differences were observed in noradrenaline, plasma renin activity, and troponin levels between groups. Cirrhosis-related clinical events, including hospitalizations and mortality, were not significantly different between the two groups. Six months of therapy with beta-blocker did not ameliorate heart function and morphology in patients with cirrhotic cardiomyopathy.
conferenceObject Serum B-type natriuretic peptide is more accurate than ascites analyses in the diagnosis of heart failure-related ascites(2012) FARIAS, Alberto Q.; SILVESTRE, Odilson M.; GARCIA-TSAO, Guadalupe; SEGURO, Luis; MAZO, Daniel F.; BACAL, Fernando; ANDRADE, Jose L.; GONCALVES, Luciana L.; CARRILHO, Flair J.; D'ALBU-QUERQUE, Luiz C.conferenceObject Impact of the severity of end-stage liver disease in cardiac remodeling(2012) SILVESTRE, Odilson M.; BACAL, Fernando; RAMOS, Danusa; BELLETI, Elisangela; ANDRADE, Jose L.; PUGLIESE, Vincenzo; ANDRAUS, Wellington; FURTADO, Meive; CARRILHO, Flair J.; D'ALBUQUERQUE, Luiz C.; FARIAS, Alberto Q.Background: The impact of end-stage liver disease (ESLD) severity in cardiac remodeling of patients with cirrhosis is unknown. Our aim was to correlate the severity of ESLD with morphologic and functional heart changes. Methods: 184 patients underwent a protocol providing data on the severity of ESLD and undergoing echocardiography to assess the diameters of the left atrium and right ventricle; the systolic and diastolic diameters of the left ventricle, interventricular septum, and posterior wall of the left ventricle; systolic pulmonary artery pressure; ejection fraction; and diastolic function. Severity of ESLD was assessed by the Model for End-Stage Liver Disease (MELD) score. Results: Left-atrial diameter (r=0.323; IC 95% 0.190-0.455; p<0.001), left-ventricular diastolic diameter (r=0.177; IC 95% 0.033-0.320; p=0.01) and systolic pulmonary artery pressure (r=0.185; IC 95% 0.036-0.335; p=0.02) significantly correlated with MELD score. Patients with MELD ≥16 had significantly higher left-atrial diameter and systolic pulmonary artery pressure, compared with patients with MELD scores <16 points. Conclusions: Changes in cardiac structure and function, as assessed by echocardiography, correlate with the severity of ESLD in patients with cirrhosis.
