Anemia hemolítica autoinmune como forma de presentación de enfermedad inflamatoria del intestino / Autoimmune hemolytic anemia as a form of presentation of inflammatory bowel disease

Las anemias hemolíticas autoinmunes son las caracterizadas por la destrucción de los hematíes debida a la producción de autoanticuerpos por el paciente, dirigidos contra sus propios antígenos eritrocitarios. La asociación con enfermedad inflamatoria del intestino está descrita, pero no es de las asociaciones más frecuentes. Se presenta un caso de una paciente de 64 años de edad, que acude por diarreas y decaimiento, aparecen evolutivamente durante su ingreso lesiones ulceradas orales y perianales. Los exámenes complementarios mostraron una anemia hemolítica Coombs positiva. Los estudios endoscópicos del tubo digestivo, mostraron ulceración continua de todo el colon desde el ciego hasta el ano y pérdida de las austras, imagenológicamente se hizo evidente el aumento de tamaño del bazo en el curso de la hemólisis. Recibió tratamiento con esteroides y mesalazina por vía oral, desaparecieron las manifestaciones de hemólisis extravascular y mejoró la sintomatología digestiva. Se concluyó histológicamente como una enfermedad inflamatoria intestinal tipo colitis ulcerosa(AU)

Autoimmune haemolytic anemias are those characterized by the destruction of the red cells due to the production of autoantibodies by the patient, against their own erythrocyte antigens. The association with inflammatory bowel disease is described but it is not the most frequent associations. We present a case of a 64-year-old patient who came with diarrhea and decay, oral and perianal ulcerated lesions appeared progressively during admission. Complementary tests showed a positive Coombs hemolytic anemia, endoscopic studies of the digestive tract, continuous ulceration of all the colon from the caecum to the anus and loss of the austras, with imaging came out the enlargement of the spleen in the course of the hemolysis. Was treated with steroids and mesalazine oraly, the manifestations of extravascular hemolysis disappeared and digestive symptoms improved. Was concluded histologically as an inflammatory bowel disease type ulcerative colitis(AU)

Modalidades de imagen en la evaluación de enfermedad inflamatoria intestinal / Imaging techniques in the evaluation of inflammatory bowel disease

La enfermedad inflamatoria intestinal es una patología crónica, con una incidencia cada vez mayor. Dentro de este grupo de afecciones, la enfermedad de Crohn y la colitis ulcerosa son las más frecuentes. La enterografía por tomografía computada (ETC) y por resonancia magnética (ERM) son las modalidades de elección para la evaluación y seguimiento de la entidad, permitiendo examinar la apariencia de la mucosa, la pared intestinal, las manifestaciones extraintestinales y las complicaciones asociadas. La elección del estudio debe hacerse de acuerdo con la condición clínica de cada paciente

Inflammatory bowel disease is a chronic condition with increasing incidence. Crohn's disease and ulcerative colitis are the most common pathologies. Computed tomography (CT) enterography and magnetic resonance (MR) enterography are the methods of choice for evaluating and monitoring this entity, assessing the appearance of intestinal wall, mucosa, extra-intestinal manifestations, and associated complications. The preferred imaging methods must be selected according to the clinical conditions of the patient

Ultrasound examination of gastrointestinal tract diseases

With recent technical advances, increasing use of sonography in the initial evaluation of patients with abdominal disease may allow the detection of unexpected tumor within the abdominal cavity. Easiness of sonographic detection of bowel pathology, purposely or unexpectedly, warrants the inclusion of bowel loops during ultrasound examination when a patient complains of symptoms indicating diseases of the bowel. In patients complaining of acute abdominal symptoms or nonspecific gastrointestinal symptoms and showing signs such as abdominal pain, diarrhea, hematochezia, change of bowel habit, or bowel obstruction, sonography may reveal the primary causes and may play a definitive role in making a diagnosis. On ultrasonography, abnormal lesions may appear as fungating mass with eccentrically located bowel lumen (pseudokidney sign) or symmetrical or asymmetrical, encircling thickening of the colonic wall (target sign). In patients with mass or wall thickening detected on ultrasonography, additional work-up such as barium study, CT or endoscopy would be occasionally necessary for making a specific diagnosis.
