Respuesta inmunitaria humoral en pacientes con Colitis Ulcerosa / Introduction: Ulcerative colitis is an inflammatory bowel disease. Little is known about its causes, but genetic, environmental, immunological and bacterial factors have been suggested. Objective: Describe the humoral immune response of patients with ulcerative colitis cared for at the Institute of Gastroenterology from January 2014 to April 2015. Methods: A descriptive cross-sectional prospective study was conducted at the Institute of Gastroenterology from January 2014 to April 2015 which included all the patients diagnosed with ulcerative colitis. An evaluation was performed of clinical, endoscopic and histological variables as well as the results of immunological studies. Results: A predominance was found of the female gender, the over-49 age group and white skin. There was also a predominance of alterations in complement components C3 and C4 and immunoglobulin G. Dependence and isolated correlation was observed between the results of immunological variables and the post-diagnosis time of evolution, the Truelove and Witts clinical scale, the degree of colonoscopic and histological activity, and the degree of dysplasia for p < 0.05. Conclusions: Immune response is a predictive factor for good evolution of the disease, but it does not allow to draw an inference about colonoscopic and histological activity. Immune response, on the other hand, is not related to the clinical evaluation scale of Truelove and Witts, the degree of dysplasia, clinical extraintestinal manifestations or post-diagnosis time of evolution
