    Procedural-Related Bleeding in Hospitalized Patients With Liver Disease (PROC-BLeeD): An International, Prospective, Multicenter Observational Study
    (2023) INTAGLIATA, Nicolas M.; RAHIMI, Robert S.; HIGUERA-DE-LA-TIJERA, Fatima; SIMONETTO, Douglas A.; FARIAS, Alberto Queiroz; MAZO, Daniel F.; BOIKE, Justin R.; STINE, Jonathan G.; SERPER, Marina; PEREIRA, Gustavo; MATTOS, Angelo Z.; MARCIANO, Sebastian; DAVIS, Jessica P.

    BACKGROUND & AIMS: Hospitalized patients with cirrhosis frequently undergo multiple procedures. The risk of procedural-related bleeding remains unclear, and management is not standardized. We conducted an international, prospective, multicenter study of hospitalized patients with cirrhosis undergoing nonsurgical procedures to establish the incidence of procedural-related bleeding and to identify bleeding risk factors. METHODS: Hospitalized patients were prospectively enrolled and monitored until surgery, transplantation, death, or 28 days from admission. The study enrolled 1187 patients undergoing 3006 nonsurgical procedures from 20 centers. RESULTS: A total of 93 procedural-related bleeding events were identified. Bleeding was reported in 6.9% of patient admissions and in 3.0% of the procedures. Major bleeding was reported in 2.3% of patient admissions and in 0.9% of the procedures. Patients with bleeding were more likely to have nonalcoholic steatohepatitis (43.9% vs 30%) and higher body mass index (BMI; 31.2 vs 29.5). Patients with bleeding had a higher Model for End-Stage Liver Disease score at admission (24.5 vs 18.5). A multivariable analysis controlling for center variation found that high-risk procedures (odds ratio [OR], 4.64; 95% confidence interval [CI], 2.44-8.84), Model for End Stage Liver Disease score (OR, 2.37; 95% CI, 1.46-3.86), and higher BMI (OR, 1.40; 95% CI, 1.10-1.80) independently predicted bleeding. Preprocedure international normalized ratio, platelet level, and antithrombotic use were not predictive of bleeding. Bleeding prophylaxis was used more routinely in patients with bleeding (19.4% vs 7.4%). Patients with bleeding had a significantly higher 28-day risk of death (hazard ratio, 6.91; 95% CI, 4.22-11.31). CONCLUSIONS: Procedural-related bleeding occurs rarely in hospitalized patients with cirrhosis. Patients with elevated BMI and decompensated liver disease who undergo high-risk procedures may be at risk to bleed. Bleeding is not associated with conventional hemostasis tests, preprocedure prophylaxis, or recent antithrombotic therapy.

    Epidemiology of HCC in Brazil: incidence and risk factors in a ten-year cohort
    (2014) PARANAGUA-VEZOZZO, Denise C.; ONO, Suzane K.; ALVARADO-MORA, Monica V.; FARIAS, Alberto Q.; CUNHA-SILVA, Marlone; FRANCA, Joao I. D.; ALVES, Venancio A. F.; SHERMAN, Morris; CARRILHO, Flair Jose
    Background and aim. The lack of information about hepatocellular carcinoma (HCC) in Brazil weakens health policy in preventing deaths from the illness. The aim of this study was to establish the cumulative incidence and the risk factors for hepatocellular carcinoma development in patients under a surveillance program. Material and methods. 884 patients with compensated cirrhosis were prospectively followed up for at least five years, from August 1998 until August 2008, with at least one annual ultrasonography liver examination and serum alpha fetoprotein (AFP) measurement. Results. Among 884 patients, 72 (8.1%) developed a tumor with a median follow up of 21.4 months. In the hepatocellular carcinoma group, hepatitis C virus infection was the major etiological factor (65.3%), 56.9% (41/72) were male and the mean average age was 57 +/- 10 years. The annual incidence of hepatocellular carcinoma was 2.9%. 79.2% (57/72) of HCCs were detected within Milan Criteria, and the mean survival time was 52.3 months, significantly higher than for those outside Milan, with a mean time of 40.6 months (p = 0.0003). Conclusion. The annual incidence of HCC among this large series of Brazilian cirrhotic patients was around 2.9% with a detection rate of 8.1%, or a cumulative incidence rate over five years of 14.3%. The three variables related to HCC risk were low serum albumin [HR: 0.518 (0.46-0.78)], high AFP > 20 ng/mL [HR: 3.16 (1.86-5.38)], and ethnicity (Brazilian-East Asian descendants vs. other mixed Brazilian ethnicities) [HR: 2.86 (1.48-5.53)].

    GUT MICROBIOTA, PREBIOTICS, PROBIOTICS, AND SYNBIOTICS IN GASTROINTESTINAL AND LIVER DISEASES: PROCEEDINGS OF A JOINT MEETING OF THE BRAZILIAN SOCIETY OF HEPATOLOGY (SBH), BRAZILIAN NUCLEUS FOR THE STUDY OF HELICOBACTER PYLORI AND MICROBIOTA (NBEHPM), AND BRAZILIAN FEDERATION OF GASTROENTEROLOGY (FBG)

    ABSTRACT Over the last years, there is growing evidence that microorganisms are involved in the maintenance of our health and are related to various diseases, both intestinal and extraintestinal. Changes in the gut microbiota appears to be a key element in the pathogenesis of hepatic and gastrointestinal disorders, including non-alcoholic fatty liver disease, alcoholic liver disease, liver cirrhosis, inflammatory bowel disease, irritable bowel syndrome, and Clostridium difficile - associated diarrhea. In 2019, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Nucleus for the Study of Helicobacter Pylori and Microbiota (NBEHPM), and Brazilian Federation of Gastroenterology (FBG) sponsored a joint meeting on gut microbiota and the use of prebiotics, probiotics, and synbiotics in gastrointestinal and liver diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to provide practical information about this topic, addressing the latest discoveries and indicating areas for future studies.

    Gastrointestinal motility and absorptive disorders in patients with inflammatory bowel diseases: Prevalence, diagnosis and treatment
    (2019) BARROS, Luisa Leite; FARIAS, Alberto Queiroz; REZAIE, Ali
    Inflammatory bowel diseases (IBD), Crohn's disease and ulcerative colitis, are chronic conditions associated with high morbidity and healthcare costs. The natural history of IBD is variable and marked by alternating periods of flare and remission. Even though the use of newer therapeutic targets has been associated with higher rates of mucosal healing, a great proportion of IBD patients remain symptomatic despite effective control of inflammation. These symptoms may include but not limited to abdominal pain, dyspepsia, diarrhea, urgency, fecal incontinence, constipation or bloating. In this setting, commonly there is an overlap with gastrointestinal (GI) motility and absorptive disorders. Early recognition of these conditions greatly improves patient care and may decrease the risk of mistreatment. Therefore, in this review we describe the prevalence, diagnosis and treatment of GI motility and absorptive disorders that commonly affect patients with IBD.
