[Recurrent intestinal ischemia due to factor VIII]. / Isquemia intestinal de repetición por el factor VIII.

Intestinal ischemia is difficult to diagnose and can be caused by several etiologic processes. We report the case of a female patient with recurrent bowel ischemia due to small vessel thrombosis, which is caused by factor VIII, a procoagulant factor.

[Effect of Helicobacter pylori eradication on iron deficiency anemia of unknown origin]. / Efecto de la erradicación de Helicobacter pylori en la anemia ferropénica de origen incierto.

UNLABELLED: Iron deficiency anemia of unknown origin is a frequent cause of anemia in which etiological diagnosis is often not achieved, despite currently available diagnostic techniques. Recent studies suggest that, in the absence of digestive tract lesions, Helicobacter pylori infection could be the cause of iron deficiency anemia, due to the alterations produced in gastric iron absorption. OBJECTIVES: To evaluate whether H. pylori eradication resolves iron deficiency anemia and removes the need for oral iron administration. PATIENTS AND METHODS: We performed an observational descriptive study in patients with iron deficiency anemia refractory to treatment with oral iron administration and with out causes that could explain their anemia. Gastroscopy, ileocolonoscopy, intestinal transit study and/or endoscopic capsule were performed. Female patients also underwent gynecological study. All patients were H. pylori-positive and standard eradication therapy was administered until elimination was achieved. The patients were followed-up for a minimum of 3 months after H. pylori eradication and the need for oral iron intake after eradication was evaluated. RESULTS: Ten patients, aged 53+/-8.2 years, were included. Hemoglobin (Hbg) before treatment was 10.06+/-0.53 mg/dl, mean corpuscular volume (MCV) was 75.43+/-6.02 fl and ferritin was 6.1+/-3.28 ng/ml. Eradication therapy was administered until elimination of H. pylori. The mean time before disappearance of anemia was 4.5 months. Laboratory parameters after treatment were as follows: Hgb 12.86+/-0.75 mg/dl, MCV 85.02+/-4.8 fl and ferritin 28+/-22.19 ng/dl. CONCLUSIONS: In the absence of lesions that could explain iron deficiency anemia, this disease can be related to H. pylori infection. Eradication of this infection is closely followed by disappearance of anemia and ferropenia.

Isquemia intestinal de repetición por el factor VIII / Recurrent intestinal ischemia due to factor VIII

La isquemia intestinal es una enfermedad de difícil diagnóstico, que puede estar causada por varios procesos etiológicos. Presentamos el caso de una paciente con isquemia intestinal de repetición por procesos trombóticos en los vasos de pequeño calibre, causados por la presencia de un factor procoagulante, el factor VIII

Efecto de la erradicación de Helicobacter pylori en la anemia ferropénica de origen incierto / Effect of Helicobacter pylori eradication on iron deficiency anemia of unknown origin

La anemia ferropénica (AF) de origen incierto es una causa frecuente de ferropenia. A pesar de las técnicas disponibles en la actualidad, no se llega a establecer su diagnóstico etiológico. Recientes estudios sugieren que la infección por Helicobacter pylori podría ser causa de AF en ausencia de lesiones del tracto digestivo, debido a la alteración que se produce en la absorción gástrica de hierro. Objetivos: Evaluar si la eliminación de H. pylori consigue la desaparición de la AF y suprime la necesidad del consumo de hierro oral. Pacientes y métodos: Estudio observacional descriptivo, en el que se han incluido pacientes con AF refractaria al tratamiento con hierro oral y sin causas que la justifiquen. Se realizó una gastroscopia, una ileocolonoscopia, un tránsito intestinal y/o una cápsula endoscópica, así como un estudio ginecológico a las mujeres. Todos los pacientes presentaban H. pylori positivo, por lo que se realizó un tratamiento erradicador estándar hasta su eliminación. Se hizo un seguimiento mínimo de 3 meses tras la eliminación de H. pylori y se valoraron las necesidades de hierro oral tras la erradicación. Resultados: Se incluyó a 10 pacientes con una media ± desviación estándar de edad de 53 ± 8,2 años. La hemoglobina (Hb) antes del tratamiento era de 10,06 ± 0,53 mg/dl, el volumen corpuscular medio (VCM) de 75,43 ± 6,02 fl y la ferritina de 6,1 ± 3,28 ng/ml. Se llevó a cabo un tratamiento erradicador hasta la desaparición de H. pylori. El tiempo medio hasta la desaparición de la anemia fue de 4,5 meses. Los parámetros analíticos tras el tratamiento fueron: Hb 12,86 ± 0,75 mg/dl, VCM 85,02 ± 4,8 fl y ferritina 28 ± 22,19 ng/dl. Conclusiones: La AF de origen incierto, en ausencia de lesiones que la justifiquen, puede relacionarse con la infección por H. pylori. La eliminación de esta infección se sigue a corto plazo con la desaparición de la anemia y de la ferropenia
