Endoscopic suspect of subacute occlusive mesenteric ischemia.

A 74-year-old patient presented to our emergency department with melena for 24 hours, associated with postprandial abdominal pain, predominantly in the epigastrium, for one month. Urgent gastroscopy showed a pale mucosa with loss of vascular pattern in the gastric antrum, as well as several superficial ulcers, Forrest III, at that level and in the duodenal bulb highly suggestive of ischaemia. An abdominal computed tomography angiography (CTA) revealed a filiform celiac trunk, with calcified atherosclerotic plaques in the ostium, superior mesenteric artery and both renal arteries, with absence of enhancement in a large part of the intestinal wall, suggestive of ischaemia. An exploratory laparoscopy confirmed patchy ischaemia of the small intestine, as well as of the cecum, ascending colon, and portion of the transversus. Atherosclerosis is the most common cause of occlusive chronic mesenteric ischaemia. The 'classic triad' consisting of postprandial pain, weight loss and abdominal bruit, is found in only a minority of patients, with a significant percentage of paucisymptomatic patients due to abundant colateral circulation, making diagnosis difficult. The endoscopic finding of edema, erythema or signs of mucosal atrophy, as well as gastric or duodenal ulcers, not justified by other causes can guide us in the diagnosis. However, more distal sections of the digestive tract which are not accessible with the conventional endoscope can often be affected, and the absence of these findings, does not exclude the diagnosis. Abdominal CTA is the gold-standard imaging test. Early diagnosis of mesenteric ischaemia is a challenge in clinical practice. Recognizing its endoscopic signs can facilitate its early diagnosis and treatment.

INTRODUCCIÓN: Ustekinumab, anticuerpo monoclonal que bloquea las interleucinas 12/23, ha demostrado en ensayos clínicos su eficacia para inducir y mantener la remisión clínica en la enfermedad de Crohn (EC). Su efectividad y su seguridad en la práctica clínica real es menos conocida y podría diferir respecto a los ensayos. OBJETIVO: Evaluar en la práctica clínica su efectividad y seguridad (pauta de inducción intravenosa esencialmente), como inducción y a largo plazo, en pacientes con EC refractarios a tratamiento biológico. MATERIAL Y MÉTODOS: Análisis retrospectivo multicéntrico (6 hospitales aragoneses), que incluye a todos los pacientes (N=69) con EC en tratamiento con ustekinumab (fuese con inducción intravenosa o subcutánea) que hubiesen alcanzado al menos 16 semanas de seguimiento. La respuesta o remisión clínica se ha evaluado en las semanas 16, 24, 32 y 48 mediante el índice de Harvey-Bradshaw. RESULTADOS: Se han incluido un total de 69 pacientes, edad media 42 años, 54% hombres. Un 89,86% (IC 95% [0,805, 0,949]) de los pacientes ha presentado mejoría clínica en la semana 16 (15,95% remisión, 73,92% respuesta). En el seguimiento posterior dicha respuesta se ha mantenido. Se han identificado mediante un modelo de regresión ordinal la edad (OR 0,95, p = 0.028) y el hábito tabáquico (OR 0,19, p = 0,027) como predictores de mala respuesta al tratamiento, mientras que la necesidad de cambio de biológico por efecto adverso (OR 96, p = 0,00017) y por pérdida de respuesta secundaria (OR 7,07, p = 0,034) han sido factores predictores de buena respuesta. No se han reportado efectos adversos graves que obligasen a interrumpir el tratamiento con ustekinumab. CONCLUSIÓN: Ustekinumab es efectivo y seguro en la práctica clínica real para lograr la inducción y el mantenimiento de la respuesta en pacientes con EC refractaria. El tabaco y la edad han mostrado ser predictores de mala respuesta, mientras que la indicación por efecto adverso a biológico previo y por pérdida de respuesta secundaria han mostrado ser predictores de buena respuesta

INTRODUCTION: Ustekinumab, a monoclonal antibody that blocks interleukins 12/23, has proven in clinical trials its efficacy in inducing and maintaining clinical remission of Crohn's disease (CD). Its effectiveness and safety in actual clinical practice is less known and may differ from trials. OBJECTIVE: To evaluate its effectiveness and safety in clinical practice (intravenous induction pattern essentially), such as induction and over the long term, in patients with CD refractory to biological treatment. MATERIAL AND METHODS: Multicentre retrospective analysis (6 hospitals in Aragón), which includes all patients (N=69) with CD undergoing treatment with ustekinumab (either with intravenous or subcutaneous induction), who had at least 16 weeks of follow-up. The clinical response or remission has been evaluated at weeks 16, 24, 32 and 48 using the Harvey-Bradshaw index. RESULTS: A total of 69 patients have been included, mean age 42 years, 54% men. A percentage of 89.86 (95% CI [0.805, 0.949]) of the patients presented clinical improvement at week 16 (15.95% remission, 73.92% response). In the subsequent follow-up, this response has been maintained. Age (OR 0.95, P=.028) and smoking habits (OR 0.19, P=.027) have been identified by an ordinal regression model as predictors of poor treatment response while the need for biological change due to adverse effect (OR 96, P=.00017) and due to loss of secondary response (OR 7.07, P=.034) have been predictors of good response. No serious adverse effects have been reported that forced them to stop taking ustekinumab. CONCLUSION: Ustekinumab is effective and safe in real clinical practice to achieve induction and maintenance of the response in patients with refractory CD. Tobacco and age have been shown to be predictors of poor response, while the indication for adverse effect to previous biological and for loss of secondary response has been shown to be predictors of good response
