ABSTRACT

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 patient’s geographical origin.

ABSTRACT

El Consenso Venezolano de Enfermedad por Reflujo Gastroesófágico (ERGE) se realizó con el objeto de proveer guías para mejorar la identificación, el diagnóstico y el tratamiento de este trastorno en el país. Los coordinadores establecieron las líneas de consenso, basado en una revisión sistemática de la literatura médica de los últimos 15 años a partir de 1995. Participaron 55 miembros con el aval de sus respectivas cátedras y sociedades locales de gastroenterología. Éstos revisaron y presentaron los temas con sus niveles de evidencia y grados de recomendación para discutirlos y votarlos en una reunión plenaria. Tras un informe final de los miembros, los coordinadores prepararon las declaraciones finales. El consenso concluyó que la enfermedad por reflujo gastroesofágico tiene una prevalencia estimada del 11,54% en Venezuela, a predominio del sexo femenino (Grado B). El diagnóstico es fundamentalmente clínico, basado en la presencia de síntomas típicos y/o atípicos, e incluso síntomas de alarma que sugieren alguna complicación (Grado B). La endoscopia es importante en la investigación de la presencia de esofagitis de reflujo y laringitis de reflujo (Grado B). Las otras pruebas diagnósticas como lo son la pHmetría esofágica de 24 horas con o sin impedancia intraluminal multicanal son importantes en los pacientes que no tienen esofagitis, tienen síntomas atípicos o cuando hay falla en la respuesta al tratamiento médico (Grado B). La radiología, manometría esofágica y el ultrasonido endoscópico no están indicados en el diagnóstico de la ERGE (Grado B). El objetivo del tratamiento es reducir la exposición ácida en el esófago y con esto: aliviar los síntomas, cicatrizar las lesiones en la mucosa esofágica, prevenir la recurrencia y las complicaciones. Los inhibidores de bomba de protones deberían ser la primera opción en el tratamiento en el síndrome de ERGE y en la esofagitis por reflujo tanto en la fase aguda como durante el mantenimiento...


The Venezuelan Gastroesophageal Reflux Disease (GERD) Consensus was carried out in order to provide guidelines to improve the identification, diagnosis and treatment of this illness in Venezuela.  The coordinators established the consensuslines, based on a systematic revision of the medical literature of the last 15 years starting from 1995. 55 physicians participated with the support of their respective medical schools and local societies. They revised and presented the topics with their respective evidence levels and recommendation grades to discuss and vote them in a plenary meeting. After a final report of the members, the coordinators prepared the definitive declarations. The consensus concluded that GERD prevalence in Venezuela is 11,54%, higher in women than men (Grade B). The diagnosis is mainly clinical, based on the presence of typical and/or atypical symptoms and alarm symptoms that may suggest the presence of complications (Grade B). Endoscopy is important when reflux esophagitis and laryngitis are present (Grade B). Other diagnostic tests as ambulatory 24 hours pH monitoring with or without multichannel intraluminal impedance are important in patients without esophagitis, with atypical symptoms or when there is flaw in the answer to the medical treatment (Grade B). Radiology, esophageal manometry and endoscopic ultrasonography are not indicated in the diagnosis of GERD (Grade B). The objective of the treatment is to reduce the presence of acid in the esophagus and consequently: alleviate the symptoms and heal lesions in the esophagus mucosa to prevent recurrence and complications. Proton pump inhibitors should be the first option drug in the treatment of GERD syndrome andin esophagitis during the acute and the maintenance phase using standard or half dose (Grade A). So far, pokinetics are drugs with a limited use in GERD patients; they stimulate the esophagus/gastric motility...

ABSTRACT

Los objetivos del presente trabajo fueron: establecer la seroprevalencia de la infección por Helicobacter pylori en población venezolana y su asociación con trastornos gastroduodenales y evaluar la presencia del gen cagA mediante la reacción en cadena de la polimerasa y su asociación con trastornos gastroduodenales. Para el estudio de seroprevalencia se evaluaron un total de 1041 personas de distintos estados del país, 370 adultos sintomáticos, 406 asintomáticos, 27 niños sintomáticos y 238 asintomáticos. La determinación de anticuerpos IgG específicos se realizó mediante ELISA comercial. La presencia del gen CagA fue evaluada en 133 pacientes del área metropolitana y el Centro de Cáncer Gástrico de San Cristóbal. Las biopsias se analizaron por diferentes métodos de diagnóstico para H. pylori: cultivo, prueba de ureasa, reacción en cadena de la polimerasa. En la población infantil el porcentaje de niños con valores de anticuerpos IgG específicos anti-H. pylori varía de 30 por ciento a 60 por ciento. En adultos sintomáticos la seroprevalencia varía entre un 68 por ciento a 93 por ciento según el área geográfica estudiada. Una disminución de anticuerpos IgG anti- H. pylori se observó en pacientes con gastritis antral difusa asociada con metaplasia tipo II. En el grupo de pacientes de San Cristóbal se observaron títulos elevados en pacientes con gastritis antral difusa. Un 46 por ciento de las cepas de H. pylori aisladas de pacientes del Area Metropolitana presentaron el gen cagA a diferencia de grupo de San Cristóbal donde se observó una frecuencia menor (26,41 por ciento).

ABSTRACT

El propósito de este estudio fue determinar el perfil de susceptibilidad de Helicobacter pylori a los antimicrobianos usados para el tratamiento de esta infección. Entre 1998 y 1999 se investigó la concentración inhibitoria mínima (CIM) para amoxicilina, claritromicina, tetraciclina y mentronidazol a 45 cepas de Helicobacter pylori aisladas de pacientes del Servicio de Gastroenterología del Hospital Vargas de Caracas, encontrándose los siguientes resultados: 30 cepas (67 por cientos) resistentes a metronidazol, 3 (7 por ciento) resistentes a claritromicina, 3 (7 por ciento) resistentes a tetraciclina, 4 (9 por ciento) fueron multirresistentes y el resto de las cepas fueron sensibles a todos los antibióticos probados. Ninguna cepa mostró resistencia a amoxicilina. Este patrón de resistencia, parecido al reportado por otros países en desarrollo, confirman la necesidad de realizar pruebas de susceptibilidad para la elección de una adecuada combinación de antibióticos que permita la erradicación y control de la infección por Helicobacter pylori en nuestro país

ABSTRACT

El propósito de este estudio fue evaluar la utilidad de un ensayo inmunoenzimático (HpSA) para la detección de Helicobacter Pylori en heces. Se estudiaron 80 pacientes del Servicio de Gastroenterología del Hospital Vargas de Caracas, con indicación de endoscopia digestiva superior, a quienes se tomó muestras de mucosa gástrica para histología, prueba rápida de ureasa, cultivo y sangre para serología. Se consideró infectado cuando el cultivo ó 2 de las otras pruebas eran positivas. Se determinó la presencia de antígenos de helicobacter pylori en heces mediante la prueba de HpSA, y los resultados se compararon con el criterio de positividad, observándose una sensibilidad de 100 por ciento y especificidad de 79 por ciento. Estos resultados sugieren que la prueba HpSA es un método no invasor, de fácil realización aunque costoso, útil para el diagnóstico primario de infección por Helicobacter pylori

ABSTRACT

PURPOSE: To present a new easy-to-perform technique for the treatment of peripheral corneal defects (perforation or significant thinning), which has had good results. METHODS: This technique, which consists in sliding and suturing a limbal based inverted scleral flap (similar to the scleral flap used in glaucoma surgery) over the affected peripheral cornea, is described. We present 7 cases: one dellen, two marginal ulcers, two perforating traumatisms, one descematocele and one case of corneal thinning after pterygium surgery. RESULTS: All 7 cases were satisfactorily resolved without modifying either the astigmatism or visual acuity. CONCLUSIONS: This is an easy-to-perform technique which offers good results and although it has some limitations, it can be recommended for the treatment of many peripheral corneal defects (perforations and significant thinning).

ABSTRACT

Objetivo: Presentamos una nueva técnica para el tratamiento de las lesiones corneales periféricas (perforaciones o adelgazamientos importantes) de fácil realización y con buenos resultados finales. Material y métodos: Describimos la técnica, que consiste en el deslizamiento de un tapete escleral invertido con base en limbo (similar al colgajo escleral que se hace en la cirugía de glaucoma) que sobreponemos y suturamos sobre la córnea periférica afectada. Presentamos siete casos (un Dellen, dos úlceras marginales, dos traumatismos perforantes, un descemetocele y un adelgazamiento corneal tras cirugía de pterigión). Resultados: En los siete casos presentados, se consiguió la resolución ad integrum, sin modificación del astigmatismo ni de la agudeza visual. Conclusiones: Se trata de una técnica sencilla en su realización y con buenos resultados finales, que si bien tiene sus limitaciones, se puede aplicar a un buen número de defectos corneales periféricos (perforaciones o adelgazamientos importantes).

ABSTRACT

UNLABELLED: Helicobacter pylori is a gram negative curved bacillus recognized as etiologic agent of chronic gastritis and an important factor in the development of duodenal ulcer and gastric cancer. The purpose of this work is to evaluate three microbiologic methods for diagnosing H. pylori infection. We studied 375 samples from 218 patients, who consulted at the Department of Gastroenterology of the Hospital Vargas and were candidates for endoscopy. Samples of gastric mucous tissue were taken at level of the antrum and each sample was stained with Gram, tested for urease and cultured. RESULTS: whit H. pylori positive 123 patients with duodenal ulcer at the endoscopy (91.1%), 17 had gastric ulcer (76.5%), 40 gastritis and/or duodenitis (60.0%), 1 duodenal ulcer and gastric (100.0%) and 37 normal endoscopies (56.8%). Evaluating the three methods used we found that of the 286 H. pylori positive samples, the Gram stain detected 282 (sensibility 98.6% and specificity 96.6%); the urease test 276 (sensibility 96.5% and specificity 98.6%) and culture was positive in 255 samples (sensibility 89.2% and specificity 100.0%). These results show that both the Gram stain and Urease test are useful for diagnosing H. pylori infection due to their high sensitivity and specificity, rapidness, low cost for the Gram stain, and easy interpretation for Urease test. Culture, even though less sensitivity++, represents the most unquestionable diagnosis and permits carrying out susceptibility to antimicrobials tests.

ABSTRACT

Enzyme-linked immunosorbent assays (ELISA) have been developed to diagnose H. pylori infection. However, the methods are not standardized. We therefore evaluated the sensitivity of ELISA developed in our laboratory in a study population comprising 38 patients with dyspeptic symptoms and 41 healthy children under 10 years. The assays for immunoglobulin G used a pool of sonicated isolates of H. pylori from five patients with dyspeptic symptoms. Serum levels IgG antibodies to cell sonicates of H. pylori were significantly higher (p < 0.001) in patients with positive culture than in the control group. Cutoff score of 0.231 for positive results was determined with mean + 3ds of the healthy group analyzed. On the basis of this survey, we conclude that a serum dilution of 1:300 and 5 micrograms/ml of antigen, are the optimal condition for rapid screening with high sensitivity of 92% of symptomatic patients for the presence of H. pylori.

ABSTRACT

60 patients with Helicobacter pylori (Hp) infection and duodenal ulcer (DU) were randomized to received either: I) Two weeks of bismuth subcitrate, metronidazole and amoxicillin (TG) or II) Omeprazole for four weeks (OG). Endoscopy and antral biopsies were done at entry and four weeks after treatment, control endoscopy was performed 2-4-8 and 12 weeks after inclusion in the trial. Healing was similar in both groups at two four weeks. At twelve weeks DU recurred in OG 65% vs 13.36% in TG and Hp infection was present. Our results showed that Hp eradication healed DU in a similar rate than Omeprazole providing further evidence of a causal link between Hp infection and duodenal ulcer.

ABSTRACT

We included 63 patients (p) with duodenal ulcer and Helicobacter pylori infection to be treated with Famotidine 40mg/day for six weeks. In the first ten days one group of 33p (TG) received Metronidazole 250mg plus Amoxicillin 500mg T.I.D and 30p (PG) placebo. Helicobacter pylori was eradicated in 62.5% of TG. Infection was always associated with ulcer recurrence. Healing was similar in both groups but recurrence was statistically significant after three month in PG and in the first year all Pg had relapsed. At 44 month only 25% of TG relapsed. The natural history of peptic ulcer disease was changed with Helicobacter pylori eradication.

ABSTRACT

Portal Hypertensive Gastropathy (PHG) diagnosed in 42 patients by upper gastrointestinal endoscopy and was correlated with histological findings of gastric biopsies taken from fundus-body and antrum and observed blinded by the pathologist. We found that in the fundus PHG was observed in 97.14% and of these 77.14% were mosaic pattern. Submucosal vessel dilatation was observed in 65.71%, congestion in 60% and chronic gastritis in 62.85%. Histologic and endoscopic correlation was possible in 85.71%. Our results show a histologic and endoscopic correlation.

ABSTRACT

El objetivo principal del presente trabajo consiste en la utilización del método de inmunotransferencia para la evaluación de la respuesta humoral de IgG e IgA en pacientes con úlcera duodenal y comprobada infección por H.pylori. Los patrones de reactividad de anticuerpos de IgG frente a los antígenos de superficie de H.pylori son muy variables, a diferencia de la respuesta de IgA, la cual se encuentra restringida a los antígenos de 74,67 y 58 kDa en el 60 por ciento de los pacientes con UD. La presencia persistente de IgA en estos pacientes reflejaría la actividad de la inmunidad local de la mucosa gastroduodenal y permitiría evaluar la infección en pacientes sintomáticos y asintomáticos. Las pruebas serológicas, por su carácter de no agresivas, constituyen una herramienta de gran utilidad para la realización de estudios epidemiológicos

ABSTRACT

Splenic abscess remains a rare entity, reserved for patients with predisposing factors or immunosuppressive conditions. In our 13 patients in which a splenic abscess was diagnosed pre- or intra-operatively, an average of 14 days past before the diagnosis was made. Main symptoms were fever, upper left abdominal pain, auscultatory left basal anomalies and splenomegaly. Culture from the spleen material included E. coli, Staphylococcus, Proteus, Salmonella and Streptococcus v. Although splenectomy has been considered the standard procedure for this pathology, we treated our last three patients by means of Computed Tomography Percutaneous Drainage (C.T.G.P.D.). There was no need for splenectomy after this procedure and there were no complications associated with the C. T. G. P. D.

ABSTRACT

Portal Hypertension (PH) was diagnosed in 114/4145 patients (p) evaluated by upper gastrointestinal endoscopy during 1991-92 (2.75%). Portal hypertensive gastropathy (PHG) was found in 39.47% p. Mild PHG was observed in 82.22% and esophageal varices grade was directly correlated to PHG presence. This is a new entity to be considered because of its bleeding possibility in PH patients.

ABSTRACT

We studied 63 duodenal ulcer (DU) patients (p) diagnosed by upper gastrointestinal endoscopy (UGE) and Helicobacter pylori positive (HP). Patients were randomized, double-blinded to receive placebo (PG) 30p or Amoxicillin plus Metronidazole 33p (TG). All of them took Famotidine for six weeks and at this point UGE was performed. DU healing was similar in both groups. HP eradication was possible in 14/24p of TG and 4/23 of PG (58.33% vs 17.39%) difference was statistically significant. DU recurrence at 3 months was 68.75% in PG vs 11.76% in TG (p = 0.001). At the end point of the study global recurrence of DU was 3/24p in TG vs 19/23 in PG (p = 0.000001). Our findings suggest that DU recurrence is related to the presence of HP. Definitive treatment to permanently eradicate the bacteria is to be evaluated.

ABSTRACT

30 patients with non ulcer dyspepsia (NUD) were evaluated to find out if there was a relationship with Helicobacter pylori (HP) infection. Gastric biopsies from the antrum were taken and two of them sent to pathology to be stained with H&E and Warthin-Starry. The other three were sent to Microbiology, for urease-test, culture and frotis with Gram stain. To diagnose HP was necessary to get it at least in two of the performed test. This was possible in 20 (66.66%). Chronic active gastritis was observed in 15/20 (75%) and in the 3/10 HP negative patients none had histological alteration shown. Normal aspect of gastric mucosa did not predict Helicobacter pylori infection. The presence of the bacteria could not be correlated to any kind of symptoms and always was associated with chronic gastritis.
