Anti-inflammatory Effects of Herbal Preparations STW5 and STW5-II in Cytokine-Challenged Normal Human Colon Cells
2016
Inflammatory bowel diseases (IBD) are chronic relapsing intestinal disorders characterized by up-regulation of pro-inflammatory cytokines followed by invasion of immune cells to the intestinal lamina propria. Standard therapies consist of anti-inflammatory or immunosuppressive drugs. Since clinical efficiency is not satisfactory and the established drugs have massive side effects, new strategies to treat IBD are required. Herein, we investigate the protective effect of the fixed combination herbal preparations STW5 and STW5-II and the contribution of the corresponding single components in an in vitro inflammation model. The normal human colon epithelial cell line, NCM460, was treated with S…
Dzīves kvalitāte pacientiem ar iekaisīgo zarnu slimībām Latvijā
2017
Ievads: čūlains kolīts (ČK) un Krona slimība (KS) ir divas galvenās neizārstējamās iekaisīgu zarnu slimības (IZS), kuras bez slimībai specifiskajiem simptomiem būtiski ietekmē arī pacientu dzīves kvalitāti (DzK). Darba mērķi: Novērtēt pacientu ar IZS dzīves kvalitāti, korelāciju starp slimības gaitu un DzK, salīdzināt ČK un KS pacientu dzīves kvalitāti un noskaidrot, vai pastāv korelācija starp DzK un klīniskajiem un demogrāfiskiem rādītājiem. Materiāls un metodes: Tika atlasīti gan stacionēti, gan ambulatori pacienti, kuriem tika lūgts aizpildīt IZS anketu (IZSA), novērtējot sociālos, emocionālos u.c. aspektus, kā arī otru anketu ar vispārīgiem un demogrāfiskiem datiem. Rezultāti: Kopā pēt…
QSAR methods for the discovery of new inflammatory bowel disease drugs
2013
Inflammatory bowel disease (IBD) represents an important class of chronic gastrointestinal tract disease. And although there are already several useful treatments to reduce and control the symptoms, there is still no cure. One drug discovery technique used is the computer-aided (in silico) discovery approach which has largely demonstrated efficacy. Computational techniques, when used in combination with traditional drug discovery methodology, greatly increase the chance of drug discovery in a sustainable and economical fashion.This review aims to provide the most recent and important advances of in silico IBD drug discovery. While this review is mainly focused on QSAR methods, especially th…
The Enterotoxin from Clostridium difficile (ToxA) Monoglucosylates the Rho Proteins
1995
The enterotoxin from Clostridium difficile (ToxA) is one of the causative agents of the antibiotic-associated pseudomembranous colitis. In cultured monolayer cells ToxA exhibits cytotoxic activity to induce disassembly of the actin cytoskeleton, which is accompanied by morphological changes. ToxA-induced depolymerization of actin filaments is correlated with a decrease in the ADP-ribosylation of the low molecular mass GTP-binding Rho proteins (Just, I., Selzer, J., von Eichel-Streiber, C., and Aktories, K. (1995) J. Clin. Invest. 95, 1026-1031). Here we report on the identification of the ToxA-induced modification of Rho. Applying electrospray mass spectrometry, the mass of the modification…
Specific Regulation of T Helper Cell 1–mediated Murine Colitis by CEACAM1
2004
Carcinoembryonic antigen-related cellular adhesion molecule 1 (CEACAM1) is a cell surface molecule that has been proposed to negatively regulate T cell function. We have shown that CEACAM1 is associated with specific regulation of T helper cell (Th)1 pathways, T-bet–mediated Th1 cytokine signaling, and Th1-mediated immunopathology in vivo. Mice treated with anti–mouse CEACAM1-specific monoclonal antibody (mAb) CC1 during the effector phase exhibited a reduced severity of trinitrobenzene sulfonic acid colitis in association with decreased interferon (IFN)-γ production. Although oxazolone colitis has been reported as Th2 mediated, mice treated with the CC1 mAb or a CEACAM1-Fc chimeric protein…
Transanal total mesorectal excision for restorative coloproctectomy in an obese high-risk patient with colitis-associated carcinoma
2016
Transanal total mesorectal excision (TaTME) offers great potential for the treatment of malign and benign diseases. However, laparoscopic-assisted TaTME in ulcerative colitis has not been described in more than a handful of patients. We present a 47-year-old highly comorbid female patient with an ulcerative colitis-associated carcinoma of the ascending colon and steroid- refractory pancolitis. A two-stage restorative coloproctectomy including right-sided complete mesocolic excision was conducted. The second step consisted of a successful nerve-sparing TaTME and a handsewn ileal pouch-anal anastomosis. TaTME may extend the possible treatment options in inflammatory bowel disease, especially …

2017
RESUMEN Objetivos: Conocer la prevalencia de la incontinencia fecal (IF) en los pacientes con Enfermedad Inflamatoria Intestinal Crónica (EIIC) y analizar su impacto en la calidad de vida. Métodos: Estudio prospectivo aleatorizado, descriptivo y analítico en 726 pacientes con EIIC (Enfermedad de Crohn (EC) y Colitis Ulcerosa (CU)) pertenecientes al departamento de salud del Hospital Clínico de Valencia. Se excluyen pacientes<18 años, pacientes con colitis indeterminadas, portadores de colostomías, ileostomías, reservorios o deterioro cognitivo. Se recogen variables demográficas, características fenotípicas de su EIIC, antecedentes personales y actividad de la EIIC. Se evalúa la calidad de v…
STAT3 links IL-22 signaling in intestinal epithelial cells to mucosal wound healing.
2009
Signal transducer and activator of transcription (STAT) 3 is a pleiotropic transcription factor with important functions in cytokine signaling in a variety of tissues. However, the role of STAT3 in the intestinal epithelium is not well understood. We demonstrate that development of colonic inflammation is associated with the induction of STAT3 activity in intestinal epithelial cells (IECs). Studies in genetically engineered mice showed that epithelial STAT3 activation in dextran sodium sulfate colitis is dependent on interleukin (IL)-22 rather than IL-6. IL-22 was secreted by colonic CD11c+ cells in response to Toll-like receptor stimulation. Conditional knockout mice with an IEC-specific d…
