Arthritis Associated with Ulcerative Colitis: Our Experience in Palermo
2009
To The Editor: Ulcerative colitis (UC) is one of the inflammatory bowel diseases, which affects the small intestine and colon [1]. The pathophysiology of UC is not known [2, 3]. The association between arthritis and UC is well known. The authors report the frequency of arthritis in 53 Sicilian patients with UC. The diagnosis of UC was made according to criteria described by Schachter and Kirsner [4]. The involvement of sacroilitic joints was assessed radiologically according to Bennett and Burch grade (0=normal joint, 1=suspicious sacroiliitis 2=abnormal joint with sclerosis and/or erosions, 3=unequivocally abnormal with erosions, sclerosis, widening or narrowing or partly ankylosed, 4=tota…
Emergence of severe spondyloarthropathy-related entheseal pathology following successful vedolizumab therapy for inflammatory bowel disease
2018
Objectives Vedolizumab (VDZ) blocks α4β7 integrin and is licenced for the treatment of IBD. It has been associated with mild SpA-related features, including sacroiliitis and synovitis. Herein we report a series of cases demonstrating the emergence of severe SpA-associated enthesitis/osteitis following successful IBD therapy with VDZ. Methods We evaluated 11 VDZ-treated patients with IBD across seven centres who developed severe active SpA and/or enthesopathy, with the aim of characterizing the VDZ-associated SpA or entheseal flares. Imaging features demonstrating particularly severe disease were recorded. Results De novo SpA developed in 9 of 11 patients and flare of known SpA in 2 patients…
No augu izcelsmes pārtikas produktiem izolētu Yersinia enterocolitica ģenētiskā daudzveidība un virulences potenciāls
2022
Yersinia enterocolitica ir ievērojams pārtikas patogēns ar lielu ģenētisko daudzveidību. Virulences gēnu noteikšana celmiem no daudzveidīgiem avotiem var palīdzēt izvērtēt jersiniozes riskus sabiedrības veselībai. Darba mērķis bija raksturot no augu valsts izcelsmes produktiem iegūto Y. enterocolitica izolātu virulences potenciālu un ģenētisko daudzveidību, veicot pilna genoma sekvenēšanu. Darbā iekļauti 66 celmi no svaigiem dārzeņiem un salātiem. Iegūtās sekvencēs konstatēja ail (4,6%), inv (95,4%) un ystB (98,5%) virulences gēnu klātbūtni. Visi izpētītie Y. enterocolitica izolāti pieder pie nosacīti nepatogēna biotipa 1A. Izmantojot cgMLST, noteikts, ka izolāti nav ģenētiski saistīti savā…
Análisis de los factores epidemiológicos y clínicos implicados en el desarrollo de la enterocolitis necrosante
2015
La enterocolitis necrosante (ENC) es una de los procesos patológicos neonatales más graves por su elevada mortalidad (30%) y complicaciones. A pesar de los constantes avances en la atención neonatal su incidencia continua siendo elevada en el recién nacido pretérmino (RNPT), especialmente en los de peso al nacimiento inferior a 1500 g en los que se estima del 7-10%, tasa que ha sufrido escasas variaciones en los últimos años. La ECN es una enfermedad de origen multifactorial, y la sintomatología inicial muy inespecífica. Se diseñó un estudio en dos fases. En una primera fase se analizaron las características epidemiológicas y clínicas de todos los RNPT ingresados en una unidad IIIA desde 20…
Activation of NF-kappaB and IL-8 by yersinia enterocolitica invasin protein is conferred by engagement of rac1 and MAP kinase cascades.
2003
International audience; Yersinia enterocolitica triggers activation of the nuclear factor (NF)-kappaB and production of the proinflammatory chemokine interleukin (IL)-8 in intestinal epithelial cells. This activation is due to adhesion of the bacteria via their outer membrane protein invasin to the host cells. Using Clostridium difficile toxins that specifically inactivate small GTPases, and transfection of inhibitory proteins of the Rho-GTPases, we demonstrate that Rac1, but not Cdc42 or Rho, is required for activation of NF-kappaB by invasin. Invasin activated the mitogen activated protein kinases (MAPK) p38 and c-Jun N-terminal protein kinase (JNK) but not extracellular signal regulated …
Safety and potential interaction of immunosuppressive drugs for the treatment of inflammatory bowel disease in elderly patients
2021
Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, are chronic diseases associated with increased morbidity and reduced quality of life. Age may represent a risk factor for adverse events, due to the multimorbidity and polypharmacy, common in elderly patients. Elderly are often not included in clinical trials evaluating efficacy and safety of study drugs for the treatment of inflammatory bowel diseases. Several drugs, such as aminosalicylates, systemic corticosteroids, immunosuppressant drugs, biological drugs and Janus Kinase inhibitors, are available for the management of inflammatory bowel diseases. With the increasing spectrum of therapeutic options, it is th…
Clostridium difficile Induced Inflammasome Activation and Coagulation Derangements
2022
C. difficile enterocolitis (CDAC) is the most common hospital infection, burdened by an increased incidence of coagulation-related complications such as deep vein thrombosis (DVT) and disseminated intravascular coagulation (DIC) as well as a significant sepsis-related mortality. In this review, we analyzed the available data concerning the correlation between coagulation complications related to C. difficile infection (CDI) and inflammasome activation, in particular the pyrin-dependent one. The little but solid available preclinical and clinical evidence shows that inflammasome activation increases the risk of venous thromboembolism (VTE). As proof of this, it has been observed that in vitr…
Prevalence of aphthous stomatitis in patients with inflammatory bowel disease after the treatment with monoclonal antibodies: a systematic review and…
2022
Currently, the most frequently employed therapies in the treatment of inflammatory bowel diseases (IBD), i.e., Crohn's Disease (CD), Ulcerative Colitis (UC) or unclassified IBD (IBD-U) are monoclonal anti-TNFs and anti-integrin therapies, such as vedolizumab (VDZ). Forty-seven per cent of these patients present extra-intestinal manifestations, the second most prevalent being aphthous stomatitis (AS). The present study aims to investigate which of the two therapies is associated with a lower prevalence of AS after treatment. An electronic search of the MEDLINE (via PubMed), Web of Science, SCOPUS, LILACS and OpenGrey databases was carried out. The criteria used were those described by the PR…
Impacto clínico de la telemedicina en la enfermedad de Crohn y colitis ulcerosa
2021
Introducción: Los datos de eficacia de la telemedicina en enfermedad inflamatoria intestinal (EII) no son consistentes. Se desconoce su impacto en el manejo de la EII moderada-grave. Además, no existe evidencia sobre el perfil de coste-efectividad de la telemonitorización en este contexto. Objetivos: Evaluar el impacto de la monitorización remota vía web (Telemonitorización de la Enfermedad de Crohn y Colitis Ulcerosa: TECCU) sobre las variables de salud y su perfil de coste-efectividad en pacientes con EII moderada-grave, comparado con el seguimiento presencial y el telefónico. Material y Métodos: Ensayo clínico aleatorizado con 3 grupos. Se incluyeron consecutivamente pacientes adultos de…
