Incremento de Linfocitos Intraepiteliales en pacientes con Síndrome de Intestino Irritable

Arévalo, F., Aragon, V., Montes, P., Guzmán, E., Monge, E. 11 August 2014 (has links)
Diversos trabajos reportan aumento en el número de linfocitos intraepiteliales (LIE), mastocitos y células enterocromafines en pacientes con Sindrome de Intestino Irritable (SII). Muchos de estos hallazgos se basan en el uso de inmunohistoquímica que son de poca disponibilidad en hospitales generales. El objetivo del presente trabajo es estudiar los hallazgos histológicos en la biopsia de colon sólo con histoquimica en pacientes con SII comparándolos con un grupo sin SII. Fueron incluidos 25 pacientes: 16 (64%), con criterios diagnósticos de SII y 9 (36%), sin SII. Se encontró un mayor número de LIE en el grupo de SII (p=0,002). Un grupo de pacientes con criterios Roma III (41,9%) presentó LIE en el rango de Colitis Linfocitica por lo que fueron excluidos de este estudio. No se encontró diferencia estadísticamente significativa en el número de mastocitos, células enterocromafines y eosinofilos. / Several studies have shown increased numbers of intraepithelial lymphocytes (IEL), mast cells, enterochromaffin cells in colonic mucosa of patients with Irritable Bowel Syndrome (IBS). Many of these findings are based is based on immunohistochemistry results, which is not available in general hospitals. Our objective is to study the histological findings observed in colon biopsies from patients with IBS compared with a group without IBS, using only histochemistry. Twenty five (25) patients were included: 16 with IBS and 9 without IBS. We found increased numbers of IEL in patients with IBS (p=0,002). A group of patients with IBS (41.9%) who fulfilled histological criteria for lymphocytic colitis were excluded. There was no significant difference in mast cells, enterochromaffin cells or eosinophils.
