Frequency and Indications of Parenteral Nutrition in an Acute Palliative Care Unit
2015
The aim of this study was to estimate the use of parenteral nutrition (PN) in advanced cancer patients enrolled in an acute pain relief and palliative care unit of a comprehensive cancer center and the appropriateness of the criteria to select patients for PN. Fourteen out of 750 patients (1.8%) admitted to an acute palliative care unit were administered PN. Patients were referred from various settings. The mean age was 58 yr (range 37-79), and 9 were males. The mean hospital stay was 7.7 days (range 3-14), and the mean Karnofsky level was 35 (range 10-50). The principal indication was bowel obstruction. Ten patients (71%) were already receiving PN before admission, and 2 of them discontinu…
Antibodies to Cathepsin G in Crohn's disease
1992
. Antibodies directed against antigens in human neutrophils have proved to be of great diagnostic value in certain systemic vasculitides. Recent reports have focused the attention on these antigens as targets of antibodies in sera of patients with inflammatory bowel disease. We investigated the sera drawn from 60 patients suffering from biopsy proven Crohn's disease and 15 patients with active ulcerative colitis. Using sensitive enzyme-linked immunosorbent assays with purified antigens and Western blotting the following antibodies could be demonstrated: cathepsin G (cat-G) antibodies IgG 38.3%, IgM 13.3%, IgA 23.3% and antibodies against human leucocyte elastase (HLE) IgG, IgA, IgM 3.3%.

Combined Therapy with Azathioprine, Prednisolone, and Ursodiol in Patients with Primary Sclerosing Cholangitis: A Case Series
1999
No established medical therapy alters the progressive course of primary sclerosing cholangitis.To explore the potential usefulness of combined therapy with azathioprine, steroids and ursodeoxycholic acid (UDCA) in primary sclerosing cholangitis.Case series.University hospital in Mainz, Germany.15 patients with primary sclerosing cholangitis.Azathioprine (1 to 1.5 mg/kg of body weight per day), prednisolone (1 mg/kg per day initially, tapering to 5 to 10 mg per day) and UDCA (500 to 750 mg per day).Clinical and laboratory evaluation, liver biopsy, and endoscopic retrograde cholangiography (a30% change in stenosis was considered significant).After a median observation period of 41 months (ran…
IRF4 regulates IL-17A promoter activity and controls RORγt-dependent Th17 colitis in vivo
2011
The transcription factor IRF4 is involved in several T-cell-dependent chronic inflammatory diseases. To elucidate the mechanisms for pathological cytokine production in colitis, we addressed the role of the IRF transcription factors in human inflammatory bowel disease (IBD) and experimental colitis.IRF levels and cytokine production in IBD patients were studied as well as the effects of IRF4 deficiency in experimental colitis.In contrast to IRF1, IRF5, and IRF8, IRF4 expression in IBD was augmented in the presence of active inflammation. Furthermore, IRF4 levels significantly correlated with IL-6 and IL-17 mRNA expression and to a lesser extent with IL-22 mRNA expression in IBD. To further …
Enteroscopy and its relationship to radiological small bowel imaging
2009
The field of radiological small bowel imaging is changing rapidly, as is small bowel enteroscopy. New techniques allow the depiction of intraluminal, mural, and extraintestinal features of various small bowel disorders, such as Crohn disease, small bowel polyposis syndromes, small intestinal malignancies, and celiac disease. For patients requiring repeated small bowel imaging, modalities that do not use ionizing radiation, such as ultrasound or magnetic resonance imaging, should be considered.
Is Epstein-Barr virus infection associated with the pathogenesis of microscopic colitis?
2017
Abstract Background Epstein-Barr virus (EBV) has been associated with inflammation in the colon, particularly in patients with inflammatory bowel disease (IBD). Even if a relevant plasmocytosis, similar to IBD, is present in microscopic colitis (MC), the frequency of EBV infection in this setting is unknown. Objectives We aimed to compare the frequency of colonic EBV infection in patients with MC, ulcerative colitis (UC), and irritable bowel syndrome (IBS). Study design The frequency of colonic EBV infection in biopsies of 30 patients with MC, 30 patients with UC, and 30 controls with IBS was retrospectively assessed. PCR was performed to detect viral EBV DNA in colonic biopsies. In situ hy…
Impaired Health-Related Quality of Life in Inflammatory Bowel Diseases Psychosocial Impact and Coping Styles in a National German Sample
2001
The purpose of this study is to give a detailed survey of the disease-specific and generic quality of life (HRQOL) of adult patients suffering from inflammatory bowel disease (IBD) in Germany.1322 patients suffering from IBD were examined in a cross-sectional study. A questionnaire assessing disease-specific and generic quality of life, coping, and hopelessness was sent to members of the German Crohn/Colitis association.Compared to the general population, the generic HRQOL in IBD patients is significantly reduced. Active coping has a negative influence on patients' generic physical HRQOL during an active phase (beta = -0.31), while this association is not present in the case of patients in …
Replication of interleukin 23 receptor and autophagy-related 16-like 1 association in adult- and pediatric-onset inflammatory bowel disease in Italy.
2008
AIM: To investigate gene variants in a large Italian inflammatory bowel disease (IBD) cohort, and to analyze the correlation of sub-phenotypes (including age at diagnosis) and epistatic interaction with other IBD genes. METHODS: Total of 763 patients with Crohn's disease (CD, 189 diagnosed at age < 19 years), 843 with ulcerative colitis (UC, 179 diagnosed < 19 years), 749 healthy controls, and 546 healthy parents (273 trios) were included in the study. The rs2241880 [autophagy-related 16-like 1 (ATG16L1)], rs11209026 and rs7517847 [interleukin 23 receptor (IL23R)], rs2066844, rs2066845, rs2066847 (CARD15), rs1050152 (OCTN1), and rs2631367 (OCTN2) gene variants were genotyped. RESULTS: The f…
DLG5 variants do not influence susceptibility to inflammatory bowel disease in the Scottish population
2005
Introduction: Recent data have suggested that specific haplotypic variants of the DLG5 gene on chromosome 10q23 may be associated with susceptibility to inflammatory bowel disease (IBD) in Germany. Haplotype D, notably characterised by the presence of a G→A substitution at nucleotide 113, was associated with susceptibility to Crohn’s disease (CD) whereas an extended haplotype A conferred protection. Aims: Association of DLG5 haplotypic variants with disease susceptibility, genotype-phenotype relationships, and epistasis with CARD15 was investigated in the Scottish population. Patients and methods: A total of 374 CD, 305 ulcerative colitis (UC), and 294 healthy controls (HC) were studied. Ge…
Mitochondrial dysfunction, persistent oxidative damage, and catalase inhibition in immune cells of naïve and treated Crohnʼs disease
2009
Background: Oxidative stress is considered a potential etiological factor for Crohn's disease (CD). We characterized the reactive oxygen species (ROS) generated in immune peripheral cells of CD patients, as well as their antioxidant enzyme status and the presence of oxidative damage. In addition, mitochondrial function (ΔΨm) was analyzed to detect the possible origin of ROS. Methods: Cells were obtained from patients at the onset of disease, prior to any treatment. Experiments were repeated when patients were in clinical remission. A set of experiments was carried out in a group of CD patients in persistent morphological remission. Controls were healthy volunteers who were not receiving any…
