MicroRNAs(miRNAs)are non-coding RNA molecules composed of 19–25 nucleotides that regulate gene expression and play a central role in the regulation of several immune-mediated disorders,including inflammatory bowel diseases(IBD).IBD,represented by ulcerative colitis and Crohn’s disease,is characterized by chronic intestinal inflammation associated with an increased risk of colorectal cancer(CRC).CRC is one of the most prevalent tumors in the world,and its main risk factors are obesity,physical inactivity,smoking,alcoholism,advanced age,and some eating habits,in addition to chronic intestinal inflammatory processes and the use of immunosuppressants administered to IBD *** studies have identified miRNAs associated with an increased risk of developing CRC in this *** identification of miRNAs involved in this tumorigenic process could be useful to stratify cancer risk development for patients with IBD and to monitor and assess ***,the present review aimed to summarize the role of miRNAs as biomarkers for the diagnosis and prognosis of IBD-associated *** the future,therapies based on miRNA modulation could be used both in clinical practice to achieve remission of the disease and restore the quality of life for patients with IBD,and to identify the patients with IBD at high risk for tumor development.

BACKGROUND Acute severe ulcerative colitis (ASUC) is a complication of ulcerative colitisassociated with high levels of circulating tumor necrosis factor alpha, due to theintense inflammation and faster stool clearance of anti-tumor necrosis factordrugs. Dose-intensified infliximab treatment can be beneficial and is associatedwith lower rates of colectomy. The aim of the study was to present a case of apatient with ASUC and megacolon, treated with hydrocortisone and acceleratedscheme of infliximab that was monitored by drug trough *** SUMMARYA 22-year-old female patient diagnosed with ulcerative colitis, presented withdiarrhea, rectal bleeding, abdominal pain, vomiting, and distended *** investigation, a positive toxin for Clostridium difficile and colonic dilatationof 7 cm consistent with megacolon were observed. She was treated with oralvancomycin for pseudomembranous colitis and intravenous hydrocortisone forsevere colitis, which led to the resolution of megacolon. Due to the persistentsevere colitis symptoms, infliximab 5 mg/kg was prescribed, monitored by drugtrough level (8.8 μg/mL) and fecal calprotectin of 921 μg/g (< 30 μg/g). Based onthe low infliximab trough level after one week from the first infliximab dose, thepatient received a second infusion at week 1, consistent with the acceleratedregimen (infusions at weeks 0, 1, 2 and 6). We achieved a positive clinical andendoscopic response after 6 mo of therapy, without the need for a *** accelerated infusions can be beneficial in ASUC unresponsive to thetreatment with intravenous corticosteroids. Longitudinal studies are necessary todefine the best therapeutic drug monitoring and treatment regimen for thesepatients.

The Impact of a Real-Life Inflammatory Bowel Disease Education Course for Brazilian Physicians from the Perspective of Its Participants

引用

Open Journal of Gastroenterology 2021年第9期11卷 151-160页

作者： rodrigo Fedatto Beraldo Julio pinheiro Baima Jaqueline Ribeiro de Barros Fernanda Lofiego Renosto Rogerio Saad-Hossne Ligia Yukie Sassaki Department of Internal Medicine Medical School S&#227o Paulo State University (Unesp) Botucatu Brazil Department of Surgery Medical School S&#227o Paulo State University (Unesp) Botucatu Brazil

Background: Physicians must acquire the necessary skills to provide Inflammatory Bowel Disease (IBD) patients with state-of-the-art clinical care, aiming to improve patient’s quality of life and disease outcomes. Purpose: To describe the queries and experiences of doctors enrolled in an IBD education course and to evaluate the impact of the course. Methods: A retrospective study included 100 physicians, of which 78 attended the course. A questionnaire was applied evaluating how the course had an impact on their IBD-knowledge. The 20-hour-course consisted of practical “real-life” activities and theoretical discussions. Results: The majority of doctors’ expertise was in gastroenterology (53%) and coloproctology (44%). A significant portion had no experience with biological therapy for ulcerative colitis (19.4%) or Crohn’s disease (5.05%). The main topics doctors wanted to discuss were biological therapy (93%), new drugs (74%) and differential diagnosis (64%). A considerable number of physicians did not feel confident at prescribing biological therapy before the course (44.4%), a percentage that decreased to 8.5% after the course (p Discussion: The ideal course should have a practical and theoretical component, as well as the support of an experienced multidisciplinary team. A real-life practical-theoretical IBD course proved a success at increasing IBD knowledge.

BACKGROUNDPercutaneous transluminal angioplasty and stenting represent an effectivetreatment for hepatic artery stenosis after liver transplantation. In the first yearafter stenting, approximately 22% of patients experience in-stent restenosis,increasing the risk of artery thrombosis and related complications, and 50%experience liver failure. Although angiography is an important tool for diagnosisand the planning of therapeutic interventions, it may raise doubts, especially insmall-diameter arteries, and it provides low resolution rates compared withnewer intravascular imaging methods, such as optical coherence tomography(OCT).CASE SUMMARYA 64-year-old male developed hepatic artery stenosis one year after orthotropicliver transplantation and was successfully treated with percutaneous transluminalangioplasty with stenting. Five months later, the Doppler ultrasound resultsindicated restenosis. Visceral arteriography confirmed hepatic artery tortuositybut was doubtful for significant in-stent restenosis (ISR) and intrahepatic flowreduction. To confirm ISR, identify the etiology and guide treatment, OCT wasperformed. OCT showed severe stenosis due to four mechanisms: Focal andpartial stent fracture, late stent malapposition, in-stent neointimal hyperplasia,and *** diagnostic methods can be useful in evaluating cases in which initialangiography results are not sufficient to provide a proper diagnosis of significantstenosis, especially with regard to ISR. A wide range of diagnoses are provided byOCT, resulting in different treatment options. Interventional radiologists shouldconsider intravascular diagnostic methods as additional tools for evaluatingpatients when visceral angiography results are unclear.
