BACKGROUND: Inflammatory bowel diseases (IBD) are chronic inflammatory affections of recurrent nature whose incidence and prevalence rates have increased, including in Brazil. In long term, they are responsible for structural damage that impacts quality of life, morbidity and mortality of patients. OBJECTIVE: To describe the profile of physicians who treat IBD patients as well as the characteristics of IBD care, unmet demands and difficulties. METHODS: A questionnaire containing 17 items was prepared and sent to 286 physicians from 101 Brazilian cities across 21 states and the Federal District, selected from the register of the State Commission of the “Study Group of Inflammatory Bowel Disease of Brazil” (GEDIIB). RESULTS: The majority of the physicians who answered the questionnaire were gastroenterologists and colorectal surgeons. More than 60% had up to 20 years of experience in the specialty and 53.14% worked at three or more locations. Difficulties in accessing or releasing medicines were evident in this questionnaire, as was referrals to allied healthy professionals working in IBD-related fields. More than 75% of physicians reported difficulties in performing double-balloon enteroscopy and capsule endoscopy, and 67.8% reported difficulties in measuring calprotectin. With regard to the number of patients seen by each physician, it was shown that patients do not concentrate under the responsibility of few doctors. Infliximab and adalimumab were the most commonly used biological medicines and there was a higher prescription of 5-ASA derivatives for ulcerative colitis than for Crohn’s disease. Steroids were prescribed to a smaller proportion of patients in both diseases. The topics “biological therapy failure” and “new drugs” were reported as those with higher priority for discussion in medical congresses. In relation to possible differences among the country’s regions, physicians from the North region reported greater difficulty in accessing complementary exams while those from the Northeast region indicated greater difficulty in accessing or releasing medicines. CONCLUSION: The data obtained through this study demonstrate the profile of specialized medical care in IBD and are a useful tool for the implementation of government policies and for the Brazilian society as a whole.

-Background -Crohn's disease accompanied by nonspecific or idiopathic ulcerative proctocolitis corresponds to a condition called intestinal inflammatory disease. The immunoexpression of cyclooxygenase 2 (COX-2) in Crohn's disease becomes more marked with progression of the disease and the presence of wild-type p53 suppresses the transcription of COX-2. Aims -To investigate the immunoexpression of cyclooxygenase 1 (COX-1), COX-2 and p53 in Crohn's ileocolitis and to correlated this expression with clinical and histopathological parameters. Methods -Forty-five cases of Crohn's disease, 16 cases of actinic colitis (diseased-control group) and 11 cases without a history of intestinal disease (normal control group) were studied. Hematoxylin-eosin-stained sections were submitted to histopathological analysis and the immunohistochemical expression of COX-1, COX-2 and p53 was evaluated by the streptavidin-biotin-peroxidase method. Results -Sixty percent of the Crohn's disease patients were women and 40% were men, with 75.5% whites and 25.5% non-whites. The disease involved the terminal ileum in 44.5% of cases, ileum in 33.3%, colon in 20% and duodenum-ileum in 2.2%. A significant association was observed between COX-2 immunoreactivity and age ≤40 years. Histopathological analysis of Crohn's disease samples showed mild or moderate crypt distortion (57.8% and 35.6% of cases), atrophy (6.6%), mild, moderate and marked chronic inflammation (46.7%, 26.7% and 20%), acute inflammatory activity (93.3%), ulceration (24.4%), mucin depletion (37.8%), Paneth's cells (24.4%), intraepithelial lymphocytes (93.3%), and subepithelial collagen (6.7%). In the CD group, COX-1 immunoreactivity in epithelial and inflammatory cells was observed in 26.7% and 22.2% of cases, respectively.

Ulcerative colitis (UC) is a disease of the colon and rectum characterized by a nonspecific chronic inflammation mediated by the concerted response of cellular and humoral events. Prostaglandins are synthesized by cyclooxygenase (COX)-1 and -2 and exhibit both pro-and anti-inflammatory activity. To evaluate COX-1 and COX-2 immunoexpression in 42 cases of UC and to correlate it with clinicopathological parameters, COX-1 and COX-2 expression was investigated by the immunohistochemistry method. Only patients with all pertinent clinical and evolutive data as well as with adequate biopsy material were included in the study. Fifteen samples of colorectal adenocarcinoma and 14 of large bowel with no histological changes were used for positive and negative controls, respectively. UC patients showed COX-1 immunoreactivity in epithelial cells in 29% of the cases and in inflammatory cells in 43%. COX-2 positivity in epithelial and inflammatory cells was found in 69% of the samples. The comparison between UC and the control groups revealed that the UC group had significantly more positive cases for COX

Background -Inflammatory bowel diseases are immune-mediated disorders that include Crohn's disease (CD) and ulcerative colitis (UC). UC is a progressive disease that affects the colorectal mucosa causing debilitating symptoms leading to high morbidity and work disability. As a consequence of chronic colonic inflammation, UC is also associated with an increased risk of colorectal cancer. Objective -This consensus aims to provide guidance on the most effective medical management of adult patients with UC. Methods -A consensus statement was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's Disease and Colitis [GEDIIB]). A systematic review including the most recent evidence was conducted to support the recommendations and statements. All recommendations/statements were endorsed using a modified Delphi Panel by the stakeholders/experts in inflammatory bowel disease with at least 80% or greater consensus. Results and conclusion -The medical recommendations (pharmacological and non-pharmacological) were mapped according to the stage of treatment and severity of the disease onto three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/ patient monitoring after initial treatment. The consensus targeted general practitioners, gastroenterologists and surgeons who manage patients with UC, and supports decision-making processes by health insurance companies, regulatory agencies, health institutional leaders, and administrators.
