Colitis y gastritis colagenosas
Mapeo topográfico de gastritis colagenosa
En contraposición con la apreciación habitual que se tiene de la gastritis colagenosa, la misma sería un proceso inflamatorio distintivo, más extensivo y difuso.
Una mujer de 74 años de edad fue investigada por dolor abdominal y diarrea. El grupo investigador realizo sobre la pacientes exámenes endoscópicos que incluyeron biopsias del estómago y del colon. Dichos exámenes, evidenciaron depósitos subepiteliales típicos característicos de la gastritis colagenosa y de la colitis colagenosa. Por su parte, los métodos histoquímicos y ultraestructurales confirmaron la presencia de colágeno en los depósitos subepiteliales. La distribución topográfica de estos depósitos de colágeno y su relación con el proceso inflamatorio en el estómago fueron definidos luego por mapeo endoscópico y biopsias de múltiples sitios de la mucosa en el cuerpo y el antrum gástrico.
Los estudios realizados indican que, a pesar de la apreciación corriente que se tenía de la gastritis colagenosa, dicha patología no sólo es un proceso inflamatorio distintivo, sino que también es más extensivo y difuso.
