ABSTRACT
RESUMEN Los granulomas epitelioides son hallazgos característicos de un grupo de pacientes con enfermedad de Crohn (EC), pero su significancia con respecto a la severidad y progresión de la enfermedad es aún incierta. Objetivo: Evaluar las características clínicas de los pacientes con EC en relación a la presencia o no de granulomas en los hallazgos histológicos. Materiales y métodos: Estudio observacional, descriptivo, retrospectivo en pacientes con diagnóstico de EC desde enero 2004 a diciembre 2019 en el servicio de gastroenterología del Hospital Nacional Guillermo Almenara Irigoyen, Lima-Perú. Resultados: Se incluyó 55 pacientes con media de edad de 56 ± 8,2 años. La mediana de tiempo de enfermedad fue de 16 meses. Tener dos o más recaídas al año (p<0,001; OR= 9,75), edad menor a 30 años (p<0,001; OR=3,57) y un CDAI moderado a severo (≥220 puntos, OR= 11,4; p<0,008) se asoció significativamente con la presencia de granulomas. La actividad endoscópica severa (p<0,003; OR= 9,91) y el fenotipo estenosante-penetrante (p<0,001; OR= 22,1) también mostraron asociación con la presencia de granulomas. El grupo de granulomas presentó mayor probabilidad de uso de corticoides (p<0,024; OR= 3,92) e inmunomodulador (p<0,001; OR= 7,10) además de necesidad de cirugía de resección intestinal (p< 0,027; OR: 5,07). Conclusiones: La presencia de granulomas en EC podría asociarse a mayor severidad clínica, endoscópica, requerimiento de terapia inmunosupresora y mayor necesidad de resección intestinal.
ABSTRACT Epithelioid granuloma is a characteristic histological feature of Crohn's disease (CD), but their significance with respect to the severity and progression of the disease is still uncertain. Objective: To evaluate the clinical characteristics of CD patients in relation to the presence or not of granulomas in histological findings. Materials and methods: An observational, descriptive, retrospective study in patients diagnosed with CD from January 2004 to December 2019 in the gastroenterology department of the Guillermo Almenara Irigoyen National Hospital, Lima-Peru. Results: 55 patients were included. Average age of 56 ± 8.2 years. The median time of disease was 16 months. Have two or more relapses per year (p<0.001; OR=9.75), age less than 30 years (p<0.001; OR=3.57) and a moderate to severe CDAI (≥220 points, OR=11.4, p <0.008) was significantly associated with the presence of granulomas. Severe endoscopic activity (p <0.003; OR=9.91) and the stenosing-penetrating phenotype (p<0.001; OR=22.1) also showed association with the presence of granulomas. The group of granulomas had a higher probability of corticosteroid use (p <0.024; OR=3.92) and immunomodulator (p <0.001; OR=7.10), besides the need for intestinal resection surgery (p<0.027; OR=5.07). Conclusions: The presence of granulomas in CD may be associated with increased clinical severity, endoscopic severity, immunosuppressive therapy requirement and undergo for intestinal resection.

Ulcerative colitis is a chronic inflammatory disease characterized by a recurrent and remitting course. Clinical remission and mucosal healing are the current therapeutic goals in management. The histological remission could be a better objective because of its prognostic impact. OBJECTIVE: To evaluate endoscopic and histological activity as predictors of clinical relapse in patients with ulcerative colitis. MATERIALS AND METHODS: Prospective descriptive study conducted from January 2015 to June 2018 at Guillermo Almenara Irigoyen National Hospital. Thirty-three patients diagnosed with ulcerative colitis who presented clinical remission after a flare were evaluated. Endoscopic remission was assessed (Mayo Score ≤1) after 6 months of follow- up with ileocolonoscopy and rectosigmoid biopsies. Histological remission was defined as score < 2 in the Simplified Geboes Score (SGS). Follow-up was performed for one year to observe relapses. RESULTS: 26 (78.8%) patients achieved endoscopic remission at 6 months (mean age 53 years, males 57.7%). Histological remission was observed in 69.2% (18/26). After 1 year of follow-up, 83.3% (15/18) of the patients who presented clinical, endoscopic and histological remission remained clinically asymptomatic. The RR of clinical relapse at one year was 3,18 (95% IC, 1,58-6,42, p=0,004) in patients without endoscopic remission and 4 (95% IC, 1,34-11,94, p=0,003) in patients without histological remission. CONCLUSIONS: Histological activity could be a better predictor of relapse compared to endoscopic remission, and should be the final therapeutic objective in the management of patients with ulcerative colitis.
