Understanding the delayed onset of action of azathioprine in IBD: are we there yet?

2009

In this issue of Gut , Ben-Horin et al propose an innovative explanation for the well known phenomenon of the delayed onset of action of thiopurines ( see page 396 ). They thereby contribute to an improved insight into the exact mode of action of the classic immunosuppressive drug azathioprine.1 Developing azathioprine as an innovative immunosuppressive drug in 1957, Gertrude Elion and George Hitchings laid the basis for the currently utilised concept of steroid-sparing treatment strategies in inflammatory bowel diseases (IBD).2 With regard to the evidence-based immunosuppressive capacity and clinical efficacy of azathioprine in the context of IBD as well as considering the proven long-term…

Skeletal status assessed by quantitative ultrasound and dual-energy X-ray absorptiometry in children with inflammatory bowel disease: A 2-year prospe…

2019

PURPOSE To assess the bone status in children with inflammatory bowel diseases (IBD) using quantitative ultrasound (QUS) measurement and dual-energy X-ray absorptiometry (DXA) at baseline and after two years of adequate treatment of the IBD and bone protection medication. METHODS Sixteen children (six boys) with IBD, aged 13.4±2.4 years, were examined at baseline and two years later. DXA was used to asses bone mineral density (BMD) and reference data were provided by the device's manufacturer (Hologic Explorer). QUS measurements were performed in patients and controls - 48 healthy children. RESULTS Mean Z-scores for TB- and s-BMD were significantly below zero for both, baseline and follow-u…

Impact of perioperative transfusions and sepsis on long-term oncologic outcomes after curative colon cancer resection. A retrospective analysis of a …

2020

Objective: Intra-abdominal septic complications (IASC) affect short-term outcomes after surgery for colon cancer. Blood transfusions have been associated with worse short-term results.The role of IASC and blood transfusions on long-term oncologic results is still debated. This study aims to assess the impact of these two variables on survival after curative colon cancer resection. Patients and methods: Retrospective analysis of a prospectively maintained database of patients who underwent curative surgery for colon cancer at a university hospital, between 1993 and 2010. Cox regression was used to identify the role of IASC and transfusions (alone and combined) on local recurrence (LR), disea…

Effectiveness and safety of biologics in pediatric inflammatory boweldisease: Real-life data from the Sicilian Network

2019

Background: Biological therapies have modified the disease course of pediatric inflammatory bowel disease (IBD) and are routinely used in clinical practice. Our observational study aims to evaluate effectiveness and safety of biologics in IBD. Method: Clinical benefit and safety data of 93 children with IBD, receiving biologics (Infliximab – IFX, Adalimumab – ADA, Golimumab – GOL) from January 2013 to December 2017, were extracted from the cohort of the Sicilian Network of IBD. Results: Among 87 children aged 7–17 years (63 Crohn's disease [CD], 24 Ulcerative colitis [UC]), 101 out of 108 biologic treatments were considered. Evaluation of 74 biologic treatments in CD patients at 26, 52, 104…

Protection against 2,4,6-trinitrobenzenesulphonic acid-induced colonic inflammation in mice by the marine products bolinaquinone and petrosaspongioli…

2005

Proinflammatory mediators, namely eicosanoids, reactive oxygen and nitrogen species and cytokines, are clearly involved in the pathogenesis of intestinal bowel disease. bolinaquinone (BQ) and petrosaspongiolide M (PT), two marine products with potent anti-inflammatory action, have been shown to control the production of mediators in acute and chronic inflammatory processes. Hence, we have tested here the hypothesis that BQ and PT could ameliorate inflammation and oxidative stress parameters in 2,4,6-trinitrobenzenesulphonic acid (TNBS)-induced colitis in Balb/c mice. BQ and PT were given orally in doses of 10 or 20mg/kg/day. Treatment of the animals with BQ or PT at the highest dose signifi…

Stepwise Regulation of TH1 Responses in Autoimmunity: Il-12-Related Cytokines and Their Receptors

2005

Interleukin (IL)-12 is a key cytokine of cell-mediated immune responses. Until recently, IL-12 was believed to be unique in its ability to induce the differentiation of naive T cells toward the TH1 phenotype and in its pathogenic activity, as shown in various disease models including inflammatory bowel disease. However, recently, 2 additional cytokines closely related to IL-12, IL-23 and IL-27, were discovered. Until then, the role of IL-12 was overestimated because it was believed that the p40 subunit was unique to IL-12. The discovery that IL-12 shares p40 with IL-23 and that IL-23 but not IL-12 is essential in models of chronic inflammation and autoimmunity led to a model in which IL-12 …

Trans-visceral migration of retained surgical gauze as a cause of intestinal obstruction: a case report

2008

AbstractIntroductionA retained surgical sponge in the abdomen is uncommon although it is likely that this finding is underreported in the medical literature. The intravisceral migration of retained surgical gauze is even rarer, as demonstrated by the very few cases reported.Case presentationThree years after undergoing anterior resection of the rectum, a 75-year-old man presented with symptoms of small bowel obstruction. Plain abdominal radiography and CT showed a radio-opaque marker; a foreign body was suspected, probably a piece of retained surgical gauze. An ileotomy of about 5 cm. was performed to confirm this diagnosis and remove the gauze.ConclusionAlthough rare, retained gauze in the…

Fas signaling-mediated T

2018

Fas induces apoptosis in activated T cell to maintain immune homeostasis, but the effects of non-apoptotic Fas signaling on T cells remain unclear. Here we show that Fas promotes TH9 cell differentiation by activating NF-κB via Ca2+-dependent PKC-β activation. In addition, PKC-β also phosphorylates p38 to inactivate NFAT1 and reduce NFAT1-NF-κB synergy to promote the Fas-induced TH9 transcription program. Fas ligation exacerbates inflammatory bowel disease by increasing TH9 cell differentiation, and promotes antitumor activity in p38 inhibitor-treated TH9 cells. Furthermore, low-dose p38 inhibitor suppresses tumor growth without inducing systemic adverse effects. In patients with tumor, rel…
