We have previously reported that the dendritic cell (DC) functional index cytokine interleukin-12 was significantly decreased in colorectal carcinoma (CRC) tissues. In this study, the DC infiltration pattern and the density of mature DCs (mDCs; labeled by anti-CD83 and anti-CD208) and immature DCs (iDCs; labeled by anti-CD1alpha) were characterized using(More)
BACKGROUND It has been documented that treatment with infliximab (IFX) induces remission in 1/3 of patients with moderate to severe ulcerative colitis (UC). Predictors of response could improve selection of patients with a higher probability of favorable outcome. AIM To determine predictor factors for the clinical outcome of IFX induction therapy in UC.(More)
BACKGROUND Host factors play an important role in the pathophysiology of Helicobacter pylori infection and development of gastritis and related disease. The established opinion is that the T-cell-mediated immune response to H. pylori infection is of Th1 type. Our earlier immune cell phenotype studies indicate a mixed Th1-Th2 profile of the effector cells.(More)
BACKGROUND In real-time PCR data analysis, the cycle threshold (CT) method is currently the gold standard. This method is based on an assumption of equal PCR efficiency in all reactions, and precision may suffer if this condition is not met. Nonlinear regression analysis (NLR) or curve fitting has therefore been suggested as an alternative to the cycle(More)
OBJECTIVE The immune characterization of ulcerative colitis (UC) has been unclear and controversial. One possible explanation for the discrepancies between earlier cytokine studies in UC may be the fact that the patients included were on immunosuppressive therapy. Thus, the aim of this study was to determine the tumor necrosis factor-alpha (TNF-alpha) level(More)
OBJECTIVE To study the preventive effect of a milk drink fermented with multistrain probiotics on antibiotic associated diarrhoea (AAD). DESIGN Double-blind placebo controlled study. SETTING University Hospital of North Norway. SUBJECTS AND METHODS Of 853 patients treated with antibiotics, 87 met the inclusion criteria, and were randomized to(More)
Adjacent mucosa may reflect the conflicting of host factors in response to the establishment or invasion of cancers. Characterization of anti-tumor immunity in this region may add help in understanding the immune-related mechanisms of colorectal carcinoma (CRC). In this study, adjacent non-tumor mucosa from 36 patients with colorectal adenoma (CRA), 26 with(More)
Only a fraction of Helicobacter pylori (HP)-infected individuals develop clinical disease. Recent research indicates that immunological mechanisms may be important for understanding the pathophysiology of HP infection. Differences in the individual cellular immune response may reflect the clinical diversity. The aim of the present study was to investigate(More)
Earlier studies have shown that the antral immune response in Helicobacter pylori infection has a mixed Th1-Th2-T-regulatory profile. After eradication, a chronic inflammation remains in some patients, but a follow-up study with a comprehensive cytokine profile in has not previously been published. Twelve patients with H. pylori positive peptic ulcer(More)
Cytokines have been suggested to be key factors in modulating immune response against tumorigenesis in the microenvironment. Therefore, characterization of cytokine expression along the colorectal adenoma-carcinoma sequence may add important information for understanding the immune-related mechanisms of the development of colorectal carcinoma (CRC). In this(More)
