RESUMO
INTRODUCCION: Aunque la enfermedad celíaca (EC) se asocia comúnmente a diarrea crónica, 10% de los casos pueden presentarse con constipación crónica (CC). No hay estudios que exploren la prevalencia de EC o marcadores potenciales de la sensibilidad al gluten (SG) en pacientes que consultan por CC.OBJETIVO: Determinar la prevalencia de marcadores potenciales de SG y EC en pacientes con CC que consultan a un centro terciario de referencia.METODOS: Estudio exploratorio prospectivo. Se evaluó a 121 pacientes adultos consecutivos con diagnóstico de CC funcional (67,8%) o SII-C (criterios de Roma III) con anticuerpos contra péptidos deamidados de gliadina IgA e IgG y anti-transglutaminasa tisular (DGP/tTGscreen valor corte=20). Los casos seropositivos fueron analizados con IgA tTG y todos los DGP/tTG Screen casos positivos se sometieron a biopsias endoscópicas de duodeno. La prevalencia se comparó con la de 518 sujetos (endoscopía digestiva alta por síntomas no relacionados primariamente con EC) y con la estimada para la población urbana del Gran La Plata. Se consideró diagnóstico de EC a la presencia de una enteropatía Marsh Illa o mayor en los casos seropositivos. Se consideró SG a los casos seropositivos sin enteropatía ni autoanticuerpos (IgA tTG).RESULTADOS: 10 pacientes (8,3%) y 46 sujetos del grupo control (8,9%) con CC tuvieron resultados positivos DGP/tTG Screen. 3 pacientes seropositivos con CC y 14 controles presentaron biopsia compatible con EC. Se estimó una prevalencia de 2,5% para los pacientes con CC y 2,7% para los controles. La prueba de IgA tTG fue positiva en 5 de los 10 pacientes con CC (incluidos los 2 casos diagnosticados con EC) y en 13 controles (100% y 92% de sensibilidad, respectivamente), 5 pacientes con CC fueron considerados como SG.CONCLUSIONES: Este estudio fue el primero en determinar la prevalencia en EC y SG en pacientes con CC, la cual resultó casi cuatro veces mayor que la estimada para la población general de Argentina (1/133).
INTRODUCTION: Celiac disease (CD) diagnosis is strongly associated with the presence of chronic diarrhea, but up to 10% of newly diagnosed cases may complain of chronic constipation (CC). No studies have explored the prevalence of CD or potential markers of gluten sensitivity among patients consulting for CC.OBJECTIVE: TO determine the prevalence of potential markers of gluten sensitivity and CD in a series of consecutive patients with chronic constipation attending a tertiary referral center.METHODS: An exploratory study was conducted at Gastroenterology Hospital of Buenos Aires. 121 adult consecutive patients with diagnosis of chronic constipation (67.8%) or IBS-C (Rome III criteria) were assessed for antibodies to deamidatedgliadin peptides IgA and IgG and tissue transglutaminase (DGP/tTG Screen cut-off: 20 U/mL). Seropositive cases were tested (IgA tTG) and all DGP/tTG Screen positive cases underwent duodenal biopsies. Prevalece was compared with that obtained from a control population of 518 subjects (upper endoscopy due to symptoms not primarily related to CD). Type Illa Marshs enteropathy or greater in seropositive cases was considered as CD diagnosis.RESULTS: 10 patients (8.3%) and 46 controls (8.9%) with CC had a positive DGP/tTGScreen test. 3 seropositive patients with CC and 14 controls had a CD compatible biopsy. The IgA tTG test was positive in 5 of the 10 patients with CC (including those 3 cases finally diagnosed with CD) and in 13 from control population (100% and 92% sensitivity, respectively). 5 patients with CC were considered as gluten sensitive (serology positive, but no enteropathy).CONCLUSIONS: This study was the first to determine a higher prevalence of CD and gluten sensitivity in patients complaining of CC. This prevalence was almost four times greater than that estimated for the general Argentinean population (1/133).

BACKGROUND: Irritable Bowel Syndrome (IBS) is characterized by the worsening of symptoms with a high fiber diet. This intolerance could be related to an increase in colonic bacterial fermentation. The hydrogen breath test (HBT) is a marker of the intestinal micro flora fermentative capacity. AIM: To assess if there is an association between hydrogen (H2) levels and clinical changes between diets with and without bran. PATIENTS AND METHODS: 10 women with predominantly constipated irritable bowel syndrome (Rome II criteria) received a lowfiber diet during one week. This phase was followed by a second 7 day period with the same diet but supplemented with 12 g of crude dietary fiber. At the end of both periods, patients completed a symptom scale (Lickert type) and performed a HBT. RESULTS: Comparing both periods with a different diet the median difference in the clinical scale score (-2.5) shows a tendency favorable to the diet without bran, p = 0.048. In the fiber period the median increase of 2 ppm in H2 values was not significant deferent. Neither was possible to establish an association between breath H2 and the clinical response to a fiber diet. CONCLUSIONS: In this pilot study we could not detect ary association between breath H2 levels and the clinical response to dietary fiber.

Chagas disease frequently causes megacolon. We investigated the enteric nervous systems in patients with chagasic megacolon compared to idiopathic megacolon and controls. Surgical specimens were obtained from 12 patients with chagasic megacolon (1 woman, 11 men, age range 41 to 72 y) and 9 patients with idiopathic megacolon (3 women, 6 men, age range 39 to 68 y), undergoing surgery for intractable constipation. A control group of 10 patients (9 women, 1 man, age range 43 to 75 y) undergoing left hemicolectomy for nonobstructing colorectal cancer was also studied. Colonic sections were investigated by conventional and immunohistochemical methods, also taking into consideration the presence of lymphocytes. Compared to controls, the 2 megacolon groups showed a decrease of enteric neurons (not due to increased apoptosis) and of enteric glial cells (all more important in chagasic patients). The interstitial cells of Cajal subtypes were decreased but not absent in megacolons, although an increase of the intramuscular subtype was found, suggesting a possible compensative mechanism. An increased amount of fibrosis was found in the smooth muscle and the myenteric plexus of chagasic patients compared to the idiopathic megacolon and the control group. A mild lymphocytic infiltration of the enteric plexuses (more evident in Chagas disease) was also found in megacolons but not in controls. Patients with chagasic megacolon display important abnormalities of several components of the enteric nervous system. Similar alterations, although of lesser severity, may be found in patients with idiopathic megacolon.

This study was designed to assess the various subtypes of functional constipation in a referral gastrointestinal center of a Latino-American country. All patients referred for evaluation of constipation during a 10-year period were audited, and those with functional constipation according to Rome I criteria classified by physiologic tests of colonic transit, as well as tests of anorectal and pelvic floor function. More than 70% of patients with functional constipation had evidence of pelvic floor dysfunction, whereas those with slow transit and constipation-predominant irritable bowel syndrome subtypes were less frequently represented. Even in a setting different from those most frequently reported in the literature, pelvic floor dysfunction represents the most common cause of functional constipation. Simple, physiologic testing is needed and useful for the diagnosis. This fact has therapeutic implications, especially because many such patients may benefit from biofeedback.

INTRODUCTION: Dyspepsia is a word that means bad digestion. In the conviction of which it is a question of an entity that it includes different disciplines, we realize a meeting consensus to discuss and to resolve a diagnostic and therapeutic algorithm of national order. OBJECTIVE: To agree on a national algorithm applicable to the functional dyspepsia. MATERIAL AND METHODS: In June 2005 a multidisciplinary group met to design and to propose a diagnostic and therapeutic algorithm for the functional dyspepsia. RESULTS: Priority gives to the medical-patient relationship and to the reinsurance. Then we divide the patients if they have signs of alarm. If they are present we studied them, if not we divide them, in accordance to the principal symptoms, in pain or epigastric discomfort. If they have pain we realized an endoscopy and a abdominal ultrasound scan. If they are positive, treatment of the disease. If the studies are negative or it has epigastric discomfort we propose a therapeutic test. Pain: H2 bloquers, wait 4 to 6 weeks, if it not response we propose a PPI, wait for 4 to 6 weeks, if there is no response psychiatric or psychological consultation. Discomfort: proquinetics, wait for 4 to 6 weeks if there are no answers, antidepressants in low doses, wait for 4 to 6 weeks if there are no answers, ca. bloquers, sumatriptan or trimebutina. In all cases we can add tranquillizers in anxious personality. CONCLUSIONS: A multidisciplinary dignostic and therapeutic consensus of national order for the patients with functional dyspepsia was obtained.

La dispepsia funcional es una entidad muy frecuente en la práctica diaria tanto del gastroenterólogo como de médicos clínicos y aún de los que practican otras especialidades, pero continúa siendo muy polémica desde el punto de vista de su definición, clasificación, diagnóstico y su enfoque terapéutico. Para conocer el punto de vista y los conocimientos que los médicos argentinos tienen del tema hemos realizado una encuesta virtual. Objetivos: 1) Determinar creencias, criterios y conductas édicas diagnósticas y terapéuticas más frecuentes asociadas al cuadro clínico de dispepsia funcional. 2) Determinar (estimativamente) por los médicos que respondieron, la prevalencia de dispépticos en la consulta diaria y mensual. 3) Determinar (estimativamente) por los médicos que respondieron, la prevalencia de enfermedad orgánica dentro de los pacientes que consultaron por dispepsia funcional. Población y muestra: Médicos residentes en Argentina, usuarios de red virtual IntraMed (expuestos: n=12.849). Respondieron voluntariamente 622 médicos de las siguientes especialidades: generalistas, de familia, gastroenterólogos, erontólogos, cirujanos generales y otras (muestreo no probabilístico). Fueron excluidos 43 especialistas que respondieron por no constituir una especialidad que reciba este tipo de consultas con mayor frecuencia. Fueron eliminadas las respuestas de pediatras por ser de bajísima frecuencia (3 pediatras). Lugar y período de exposición a la encuesta: Buenos Aires, Red virtual IntraMed, desde enero de 2005 a enero de 2006, encuesta colgada on-line desde el 2 al 31 de mayo de 2005. Metodología: Invitación electrónica a participar luego de una breve difusión previa. Exhibición de la encuesta on-line durante mayo de 2005. Diseño: exploratorio, prospectivo, observacional, transversal, de cuantificación. Instrumento: Cuestionario que exploróentre médicos de diferentes especialidades de la Argentina: a) Dificultades y preferencias acerca de la definición...

Introducción. Dispepsia deriva del griego y significa mala digestión. Dado que se trata de una entidad que abarca distintas disciplinas, se realizó una reunión de consenso para discutir y acordar un algoritmo diagnóstico y terapéutico nacional. Objetivo: Consensuar un algoritmo nacional aplicable a la dispepsia funcional. Material y métodos: En junio de 2005 un grupo multidisciplinario se reunió para diseñar y proponer un algoritmo diagnóstico y terapéutico para dispepsia funcional. Resultados: Darle prioridad a la relación médico-paciente, a las medidas higiénicos dietéticas y al reaseguro. Luego dividimos a los pacientes de acuerdo a si tienen o no signos de alarma. Si están presentes, se los estudia, si no, se los divide de acuerdo a los síntomas principales en dolor o malestar epigástrico. Si tienen dolor, se realiza VEDA y ecografía abdominal. Si son positivos, tratamiento de la enfermedad. Si los estudios son negativos o tiene malestar epigástrico: prueba terapéutica. La pruebas serían: Dolor: Antagonistas H2, esperar 4 a 6 semanas, respuesta negativa: IBP, esperar 4 a 6 semanas, sin no hay mejoría: consulta Psiquiátrica o Psicológica. Malestar: Proquinéticos y esperar 4 a 6 semanas. Si no hay respuestas: Antidepresivos a bajas dosis, esperar 4 a 6 semanas y si no responde: Bloqueantes Cálcicos, Sumatriptan o Trimebutina. En todos los casos se pueden sumar ansiolíticos en personalidad ansiosa. Conclusiones: Se logró un consenso diagnóstico y terapéutico multidisciplinario de orden nacional para los pacientes con dispepsia funcional.
