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 and Aim One of the most impacted regions by the pandemic globally, Latin America is facing socioeconomic and health‐care challenges that can potentially affect disease outcomes. Recent data suggest that inflammatory bowel disease (IBD) patients do not have an increased risk of the development of COVID‐19 complications. However, the impact of COVID‐19 on IBD patients living in least developed areas remains to be fully elucidated. This study aims to describe the outcomes of IBD patients diagnosed with COVID‐19 in countries from Latin America based on data from the SECURE‐IBD registry. Methods Patients from Latin America enrolled in the SECURE‐IBD registry were included. Descriptive analyses were used to summarize clinical and sociodemographic characteristics. The studied outcomes were (i) a composite of need for intensive care unit admission, ventilator use, and/or death (primary outcome) and (ii) a composite of any hospitalization and/or death (secondary outcome). Multivariable regression was used to identify risk factors of severe COVID‐19. Results During the study period, 230 cases (Crohn's disease: n = 115, ulcerative colitis: n = 114, IBD‐unclassified [IBD‐U]: n = 1) were reported to the SECURE‐IBD database from 13 different countries. Primary outcome was observed in 17 (7.4%) patients, and the case fatality rate was 1.7%. In the adjusted multivariable model, the use of systemic corticosteroids (odds ratio [OR] 10.97; 95% confidence interval [CI]: 3.44–34.99) was significantly associated with the primary outcome. Older age (OR 1.03; 95% CI: 1.00–1.05), systemic corticosteroids (OR 9.33; 95% CI: 3.84–22.63), and the concomitant presence of one (OR 2.14; 95% CI: 0.89–5.15) or two (OR 10.67; 95% CI: 1.74–65.72) comorbidities were associated with the outcome of hospitalization or death. Conclusion Inflammatory bowel disease patients with COVID‐19 in Latin America appear to have similar outcomes to the overall global data. Risk factors of severe COVID‐19 are similar to prior reports.
Despite significant advances in medical therapy in the management of Crohn’s disease (CD), surgery is still required in a significant proportion of patients and constitutes an important tool in treatment algorithms. Recently, more options of biological agents have been made available, and most patients with CD undergoing surgical procedures have been previously exposed to this class of drugs. There is controversy in the literature as to whether anti-tumor necrosis factor (TNF) agents, anti-integrins, or anti-interleukins (ILs) have a direct relationship with increased postoperative complications. In this narrative review, the authors summarize the most important data regarding the effect of biologics on postoperative outcomes in CD. Most studies (with different designs) are based on the experience with anti-TNF agents, mostly with infliximab. Some studies outlined the relationship between vedolizumab and postoperative complications, and there is a lack of data with ustekinumab in this scenario. Most studies are retrospective, but few prospective data are available. A cause–effect (proof of concept) direct relationship between biologics and an increase in postoperative morbidity has not been demonstrated to date. Several confounding factors such as previous use of steroids, malnutrition, and unfavorable abdominal conditions have a definitely effect on postoperative complications in CD. Biologics seem safe to be used in the perioperative period, but available data are still controversial. Multidisciplinary individualized decisions should be made on a case-to-case basis, adapting the surgical strategy according to risk factors involved.
BACKGROUND: The introduction of anti-TNF agents represented a landmark in the management of both Crohn’s disease (CD) and ulcerative colitis (UC), with improved efficacy and safety when compared with conventional treatment. However, significant challenges still exist in Latin America to facilitate the access of biological agents for physicians and patients. OBJECTIVE: The aim of this review was to summarize current evidence on penetration of biological agents for CD and UC in Latin America. METHODS: Data are derived from a previous complete systematic review that explored different characteristics of inflammatory bowel diseases (IBD) in Latin America. The studies fully included in this previous systematic review which contained detailed descriptions of the percentage of use of biological agents in different cohorts throughout Latin American and Caribbean countries were included, and descriptive findings were compiled, describing CD and UC penetration of these drugs in different patient cohorts from different countries. RESULTS: From the 61 studies included in the original systematic review, only 19 included data of the percentage of patients treated with biological agents. Anti-TNF use in CD varied from 1.51% in Mexico up to 46.9% in Colombia, with most of the studies describing anti-TNF use in approximately 20%-40% of CD patients. On the other side, the frequency of the use of biologics was clearly lower in UC, varying from 0% in 2009 to up 16.2% in 2018, according to two different Mexican studies. Only two studies described the penetration of anti-TNF agents in IBD overall: 13.4% in a Colombian and 37.93% in a Brazilian study. No studies described percentage of use of new biologic agents (vedolizumab and ustekinumab). CONCLUSION: Penetration of anti-TNF agents in Latin America is comparable to the rest of the world in CD, but lower in UC. With the increase in the incidence and prevalence of IBD, specific strategies to increase access to anti-TNF agents in UC and new biological agents overall are warranted.
Bowel preparation is mandatory prior to elective colonoscopy and their effectiveness is closely related to the quality of the examination. There are many preparations on the market and there is no consensus on which is best. This study aimed to compare three solutions for colon preparation in patients undergoing colonoscopy. We conducted a prospective study with 61 patients divided randomly into three groups: one that received a standard dose of macrogol, another received a standard dose of 10% mannitol and another received a standard dose of sodium picosulphate. Patients and examining endoscopists responded to questionnaires for compiling data. In the results we noticed that 10% mannitol, despite being less tolerated by the patient when compared to sodium picosulphate, presents better results in colonic cleaning, being therefore superior in this regard. Macrogol was considered as an intermediate in relation to the other two preparations. As for tolerability, preference is given to sodium picosulphate as best tolerated, followed by mannitol and by macrogol, which is poorly tolerated by the patient. We conclude that as the main objective of bowel preparation in colonoscopy is the quality of colonic cleaning, 10% mannitol was superior to the other preparations studied.
Purpose:To observe the histological alterations in the liver and biochemistry in the blood that can happen in Wistar rat, after the ligature of right hepatic duct. Methods: In this study were used rats (n=46) of Wistar pedigree. The animal groups (n=46) were distributed in 6 experimented sub-groups (n=6). It was held a ligature surgery of the right hepatic duct and euthanasia in 7, 14, 21, 28, 60 and 90 days and the biochemistry control group (n=10), that animals had 2ml of their blood taken by cardiac puncture for biochemistry study with value analyses of bilirubins, transaminasis, lactic desidrogenasis, alkaline phophatase and gamma-glutamil-transferase. Given the expected time of each group, the animals were submitted to anesthesia procedure and cavity re-opening, being held intra-cardiac puncture and with 2ml blood collected for biochemistry analyses. It was proceeded the liver resection, being the liver putted in formol solution to 10% for a period of 24 hours and taken to the histology. Results: It was not possible to identify results that express significant differences as the existence of alterations histological and biochemistrily between the different groups. Conclusion: At the end of the study, it was not possible to identify histological and biochemistrily alterations that express significant differences between livers of the animals from the right linked hepatic duct and the animals of the control group. Key words: Liver duct. Liver. Histology. Biochemistry. Rat. RESUMOIntrodução: a colestase é uma situação grave e geralmente letal.
