Diagnostic Validity of DNMT-1 and 3b Immunoreactivity in Non-neoplastic Epithelium of UC Patients with and Without Neoplasia

It is important to improve the efficacy of surveillance in UC patients with neoplasia.In the present study, we assessed the cut-off value of expression of DNMT-1 and DNMT-3b expression in the non-neoplastic rectal epithelium of patients with long-standing and extensive UC. Sixty patients with long-standing and extensive UC participated in this study( 30 with colorectal neoplasia and 30 without). Immunohistochemical analysis was performed to determine the expression of DNMT-1 and 3b in non-neoplasticrectal epithelium of UC patients without neoplasia, and in non-neoplastic rectal epithelium of UC patients with neoplasia. The level of immunoreactive DNMT-1 and DNMT-3b expression was determined as the percentage of positive cells relative to the total number of cells counted under high power magnification.DNMT-1 and 3b expression in non-neoplastic rectal epithelium of UC patients with neoplasia (0.57, range0.53-0.63)(0.32, range 0.18-0.67) was higher than in the non-neoplastic epithelium of UC patients without neoplasia (0.41, range 0.25-0.54, P=.001)(0.0, range 0.0-0.13, P<.001). ROC curve analysis confirmed0.53 and 0.07 as the best DNMT-1 and DNMT-3b cut-off values for identifying individuals at increased risk of neoplasia( area under the curve=0.798 and 0.842, respectively). The cut-off value for DNMT-1 andDNMT-3b expression in non-neoplastic rectal epithelium is therefore an efficient predictor for the increased risk of UC-associated neoplasia

Failure of Fecal Microbiota Transplantation in a Three-Year-Old Child with Severe Refractory Ulcerative Colitis

Fecal microbiota transplantation (FMT) is a treatment designed to correct gut dysbiosis by administration of feces from a healthy volunteer. It is still unclear whether FMT for children with ulcerative colitis (UC) is effective or hazardous. Here we describe a young patient to have received FMT for UC. A three-year-old girl was admitted to our hospital with severe active UC, and treated with aminosalicylates and various immunosuppressive drugs. As remission was not achieved, we decided to try FMT before colectomy. We administered donor fecal material a total of six times by retention enema (×2) and via a nasoduodenal tube (×4) within 10 days. The patient developed abdominal pain and pyrexia after each FMT session. Analyses revealed the transferred donor fecal microbiota had not been retained by the patient, who ultimately underwent colectomy. The severity of the UC and/or timing of FMT may have partly accounted for the poor outcome.Fecal microbiota transplantation (FMT) is a treatment designed to correct gut dysbiosis by administration of feces from a healthy volunteer.
