ABSTRACT
BACKGROUND: Herbal and dietary supplements (HDS) consumption, a growing cause of hepatotoxicity, is a common practice among Latin-American populations. OBJECTIVES: To evaluate clinical, laboratory features and outcome in HDS-hepatotoxicity included in the Latin America-Drug Induced Liver Injury (LATINDILI) Network. METHODS: A total of 29 adjudicated cases of HDS hepatotoxicity reported to the LATINDILI Network from October 2011 through December 2019 were compared with 322 DILI cases due to conventional drugs and 16 due to anabolic steroids as well as with other series of HDS-hepatotoxicity. RESULTS: From 367 DILI cases, 8% were attributed to HDS. An increasing trend in HDS-hepatotoxicity was noted over time (p = .04). Camellia sinensis, Herbalife® products, and Garcinia cambogia, mostly used for weight loss, were the most frequently adjudicated causative agents. Mean age was 45 years (66% female). Median time to onset was 31 days. Patients presented typically with hepatocellular injury (83%) and jaundice (66%). Five cases (17%) developed acute liver failure. Compared to conventional medications and anabolic steroids, HDS hepatotoxicity cases had the highest levels of aspartate and alanine transaminase (p = .008 and p = .021, respectively), had more re-exposure events to the culprit HDS (14% vs 3% vs 0%; p = .026), and had more severe and fatal/liver transplantation outcomes (21% vs 12% vs 13%; p = .005). Compared to other DILI cohorts, less HDS hepatotoxicity cases in Latin America were hospitalized (41%). CONCLUSIONS: HDS-hepatotoxicity in Latin-America affects mainly young women, manifests mostly with hepatocellular injury and is associated with higher frequency of accidental re-exposure. HDS hepatotoxicity is more serious with a higher chance of death/liver transplantation than DILI related to conventional drugs.

BACKGROUND/AIM: Severity of chronic gastritis associated with Helicobacter pylori infection (CGAHpI) could play a role in evaluating the potential risk to develop gastric cancer. Our aim was to estimate the risk for gastric cancer in a clinical setting, according to histopathologic criteria, by applying the gastric cancer risk index (GCRI) METHODS: Histopathologic study of the gastric biopsies (corpus-antrum) from consecutive adult patients that underwent gastroesophageal duodenoscopy was carried out, and the GCRI was applied in patients presenting with CGAHpI. RESULTS: One hundred eleven patients (77% female) with a mean age of 38.6±13.1 years were included. Active Helicobacter pylori infection (aHpi) was diagnosed in 77 cases (69.40%). In 45% of the cases with aHpi, pangastritis (23%) or corpus-predominant gastritis (22%) was diagnosed. Nine cases were diagnosed with intestinal metaplasia (8%), 7 of which (77.70%) were in the aHpi group. Twenty one percent of the patients with aHpi had a GCRI of 2 (18.10%) or 3 (2.50%) points (high risk index), while 79.10% accumulated a GCRI of 0 or 1 points (low risk index). Of the patients with no aHpi, none of them had 3 points (p=0.001). Of the 18 patients that accumulated 2 or 3 points, 6 (33.30%) presented with intestinal metaplasia (all with pangastritis and corpus-predominant gastritis), of which 4 cases (66.60%) had aHpi. CONCLUSIONS: The estimated gastric cancer risk in patients with CGAHpI in the clinical setting studied was relatively low and 5% of the patients had a histopathologic phenotype associated with an elevated risk for developing gastric cancer.

Introducción: Se ha demostrado ampliamente que el genotipo F del virus de la hepatitis B (VHB) es dominante en nuestra población Amerindia. Recientemente, nosotros identificamos que en los pacientes infectados por VHB habitantes no migratorios de áreas urbanas venezolanas prevalece también el genotipo F. Objetivo: Determinar los genotipos del VHB en portadores crónicos urbanos migratorios y compararlos con el grupo no migratorio. Material y Métodos: Se investigaron 136 portadores crónicos del VHB, 110 no inmigrantes y 26 inmigrantes de origen asiático. Se evaluaron antígeno eHB y anti-eHB y los genotipos del VHB, este último mediante PCR. Resultados: En los 110 pacientes urbanos venezolanos persistió la elevada frecuencia del genotipo F (95%) con 3 casos coinfectados, 2 por genotipos A+F y 1 caso con genotipos E+F. Interesantemente, 2 casos demostraron genotipo D del VHB. Hepatitis crónica B (HCB) antígeno-e positivo fue diagnosticada en 83 pacientes (80,6%) mientras 20 casos (19,4%) presentaron HCB antígeno-e negativo. En los pacientes asiáticos infectados con un solo genotipo se identificó el C en 11 casos, el B en 4 pacientes, el F en 3 y, en 1 caso, genotipo D. Se demostró coinfección entre estos diferentes genotipos, incluyendo un caso coinfectado con genotipo E. El genotipo F se encontró coinfectando a 4 pacientes, 2 de ellos con genotipo C. Doce casos presentaron HCB antígeno e positivo y 14 pacientes HCB antígeno e negativo. De los pacientes infectados con genotipo C, 7 de ellos (54%), incluyendo los 2 coinfectados con genotipo F, presentaron HCB antígeno-e negativo. Conclusión: Es notoria la elevada circulación del genotipo F del VHB en nuestras áreas urbanas...
Introduction: It has been widely demonstrated that the genotype F of hepatitis B virus (HBV) is dominant in our Amerindian population. Recently, we identified that genotype F is prevalent in HBV non-migratory infected patients living in urban areas. Objective: To determine the genotypes of HBV in migratory chronic carriers compared to non-migratory population. Material and Methods: We investigated 136 chronic HBV carriers, 110 non-immigrants and 26 immigrants of Asian origin. We assessed hepatitis B e-antigen and antibody and HBV genotypes, the latter using PCR. Results: High prevalence (95%) of genotype F persisted among 110 Venezuelan urban patients, with 3 co-infected patients, 2 with genotypes A+F and 1 case with E+F. Interestingly, 2 cases showed HBV genotype D. Chronic hepatitis B (CHB) e-antigen positive was diagnosed in 83 patients (80.6%) while 20 cases (19.4%) showed CHB e-antigen negative. In Asian patients infected with one sole genotype, C was identified in 11 cases, B in 4 patients, F in 3, and in 1 case, genotype D. Co-infection was demonstrated among these different genotypes, including one case co-infected with genotype E. Genotype F was found in 4 co-infected patients, 2 with genotype C. Twelve cases had CHB e-antigen positive and 14 CHB e-antigen negative. From patients infected with genotype C, 7 of them (54%), including 2 co-infected with genotype F, demonstrated CHB e-antigen negative. Conclusion: It is remarkable the high circulation of HBV genotype F in our urban areas. However, given the distinct outcome described in CHB genotype F and the identification of other genotypes rather than F in urban areas, suggests that inclusion of HBV genotypes in Venezuela, should be considered standard in the management of CHB regardless the patients geographical origin.

Introduction: Double Balloon Enteroscopy (DBE) and Endoscopic Viocapsule (EVC) were introduced in the University Hospital of Maracaibo since 2007 and 2008, respectively. Their performance in diagnosing small bowel diseases were analyzed and compared. Patients and Methods: Cases undergoing upper DBE (UDBE), lower DBE (LDBE) and/or CE, were retrospectively reviewed since the introduction of these techniques, until January 2010. Results: In 94 cases (♂: 55; ♀:39; Ages: 10 to 89), 155 diagnostic procedures were performed: 52 UDBE, 8 LDBE, 16 EVC and 79 combined procedures. Predominating indications: obscure gastrointestinal bleeding, upper and/or lower gastrointestinal bleeding, anemia, chronic diarrhea, and suspicion of an intestinal tumor. Full visualization of small bowel: 86.7% (UDBE), 57.7% (DBUE) and 100% (EVC). Biopsies, therapies and/or India ink tattooing: 58.2% (UDBE) and 23.1% (DBLE). Predominant endoscopic diagnoses: vascular malformations, parasitic enteropathies, malign tumor, ulcerative enteropathies and erosive enteropathies. Agreement indication/diagnosis: 74.3% (UDBE), 57.7% (LDBE) and 70% (EVC). Conclusions: DBE and EVC constitute efficient methods with particular advantages for diagnosing small bowel pathologies: DBE allows additional procedures; EVC provides a greater chance of full visualization of small intestine. In specific cases, combination of these tests could improve their diagnostic and therapeutic efficiency.

ABSTRACT
El propósito del estudio fue identificar las formas de presentación más frecuentes con que cursan los pacientes con enfermedad diverticular que son atendidos en el SAHUM, en el período 2003 - 2006. Se realizó una revisión de historias clínicas de pacientes con enfermedad diverticular ambulatorios u hospitalizados, que fueron diagnosticados a través de colonoscopia o métodos de imagenes, cuyos datos fueron reportados en una ficha derecolección diseñada en función de las variables del estudio. Conclusiones: la forma mas frecuente de presentación de la enfermedad diverticular fue la simple con cerca de un 50 %, además es importante resaltar que la hemorragia digestiva inferior secundaria a esta enfermedad presento una incidencia elevada comparada con la reportada a nivel mundial.
The purpose of the study was to identify the forms of presentation more frequently found in patients with diverticular disease treated at the SAHUM, in the period 2003-2006. We made a revision of clinical histories of patients with diverticular disease ambulatory or hospitalized, who were diagnosed through colonoscopy or other imaging methods, whose data were reported in a card of data collection in function of the variables of the study. Conclusions: the presentation form most frequent of the diverticular disease was the simple one with close to 50%, moreover is important to stand out that lower digestive haemorrhage secondary to this disease presented a high incidence compared with the one reported at world level.
ABSTRACT
We reviewed 286 records of patients older than 60 years with upper GI bleeding from 1985 to 1990. The average age was 72.7 +/- 8.9 y. The most common etiologies were: Gastric Ulcer 26%, Erosive gastritis 24%, Esophageal varices 16%, Duodenal Ulcer 13%, Miscellaneous 17% and Unknown causes 3%. Global mortality rate was 38% and the most frequent cause was variceal bleeding in 36%.
