BACKGROUNDInflammatory bowel diseases (IBD) have been associated with a low quality of life (QoL) and a negative impact on work productivity compared to the general population. Information about disease control, patient-reported outcomes (PROs), treatment patterns and use of healthcare resources is relevant to optimizing IBD management.AIMTo describe QoL and work productivity and activity impairment (WPAI), treatment patterns and use of healthcare resources among IBD patients in Brazil.METHODSA multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn’s disease (CD) or ulcerative colitis (UC). At enrolment, active CD and UC were defined as having a Harvey Bradshaw Index ≥ 8 or a CD Activity Index ≥ 220 or calprotectin > 200 µg/g or previous colonoscopy results suggestive of inadequate control (per investigator criteria) and a 9-point partial Mayo score ≥ 5, respectively. The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L, the Inflammatory Bowel Disease Questionnaire (IBDQ), and the WPAI questionnaire. Information about healthcare resources and treatment during the previous 3 years was collected from medical records. Chi-square, Fisher’s exact and Student’s t-/Mann-Whitney U tests were used to compare PROs, treatment patterns and the use of healthcare resources by disease activity (α = 0.05).RESULTSOf the 407 patients in this study (CD/UC: 64.9%/35.1%, mean age 42.9/45.9 years, 54.2%/56.6% female, 38.3%/37.1% employed), 44.7%/25.2% presented moderate-to-severe CD/UC activity, respectively, at baseline. Expressed in median values for CD/UC, respectively, the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2, the EQ-visual analog scale score was 80.0/70.0, and the IBDQ overall score was 164.0/165.0. Moderate to severe activity, female gender, being unemployed, a lower educational level and lower income were associated with lower QoL (P < 0.05). Median work productivity impairment was 20% and 5% for CD and UC patients, respectively, and activity impairment was 30%, the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity (75.0% vs 10.0%, P < 0.001). For CD/UC patients, respectively, 25.4%/2.8% had at least one surgery, 38.3%/19.6% were hospitalized, and 70.7%/77.6% changed IBD treatment at least once during the last 3 years. The most common treatments at baseline were biologics (75.3%) and immunosuppressants (70.9%) for CD patients and 5-ASA compounds (77.5%) for UC patients.CONCLUSIONModerate to severe IBD activity, especially among CD patients, is associated with a substantial impact on QoL, work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil.

DESCRITORES -Inibidores da bomba de prótons. Mucosa gástrica. Pólipos. ABSTRACT -Background -The medications most often prescribed and used chronically by patients with dyspeptic symptoms belong to the group of inhibitors of proton pump whose main representative is omeprazole, used clinically about 20 years. Recent studies have postulated the relationship between chronic use of this medication and macroscopic and microscopic proliferative changes in mucosal of gastric body, especially the fundic gland polyps. Aim -To analyze the frequency and type of gastric proliferative changes in chronic users of proton pump inhibitors proton and its association with age, dose, time of use, symptoms and Helicobacter pylori infection. Methods -A survey of prevalence was conducted in Digestive Endoscopy Service, Hospital de Clínicas, Federal University of Paraná, using questionnaire referring the use of these drugs and performed in subjects using this class of drugs during at least 12 months prior to the endoscopy. Gastric biopsies of fundus, body and antrum were performed in all patients. Polyps were removed when present for histopathological analysis. Research on Helicobacter pylori was done by urease test and histopathology. RESUMO -RacionalResults -Twenty-two individuals were included of which six (27.3%) had proliferative changes of the mucosa. Of these, two (9.1%) had sporadic fundic polyps and four only microscopic proliferative change as cystic glandular formation. Statistic significant (p <0.05) association between age ≥ 60 years and these changes was found. There was no association between dose of use, time of use, symptoms and Helicobacter pylori infection. Conclusions -It was observed the existence of proliferative mucosa changes in individuals with chronic use of inhibitors of proton pump. In this group, the association between age and proliferative changes was significant.

-Context -Acromegalic patients have better chances to develop colorectal polyps and cancer and, considered a high-risk group, need to undergo frequent screening examinations. Moreover, in acromegalia, the increased bowel length and the intestinal loop complexity can lead to higher levels of technical difficulties and increase the risks of complications at conventional colonoscopy. Computed tomographic colonography, also known as virtual colonoscopy, is an innovative and secure technology which is revolutionizing the diagnosis of colon and rectum neoplasias. Objective -To analyze computed tomographic colonography performance for the screening of colorectal polyps in acromegalic patients. Methods -A prospective study of 21 asymptomatic acromegalic patients, 12 male and 9 female, average age 49, who underwent computed tomographic colonography and conventional colonoscopy. Computed tomographic colonography was performed with a GE Helical Multislice Computed Tomography Apparatus. Conventional colonoscopy was performed in the same day, without previous knowledge of the computed tomographic colonography diagnostics. The study evaluated the capacity of computed tomographic colonography to detect patients with colorectal polyps and identify each colorectal lesion described by the colonoscopy. Results -In two patients (2/21), conventional colonoscopy was incomplete. However, in all patients computed tomographic colonography was complete. In Phase I ("per patient"), computed tomographic colonography diagnosed eight of the nine patients with colorectal polyps and showed 88% sensitivity, 75% specificity and 81% accuracy. In Phase II ("per polyp"), out of the 21 acromegalic patients included in this study, 12 presented normal findings at conventional colonoscopy. A total of 19 polyps were identified in 9 patients. Ten of the 19 polyps were smaller than 10 mm, and 9 were equal to or larger than 10 mm. Computed tomographic colonography identified 7 of the 9 polyps ≥10 mm described by conventional colonoscopy and only 6 of the 10 small polyps identified at conventional colonoscopy were detected by computed tomographic colonography. The histological analysis of resected lesions revealed 12 tubular adenomas, 6 hyperplastic polyps and 1 colonic tubulo-villous adenoma with an adenocarcinoma focus. Conclusion -The authors present the first reports of computed tomographic colonography in the screening of colorectal polyps in acromegalic patients. In this study, computed tomographic colonography was performed without complications and a complete and safe colorectal evaluation was possible in all acromegalic patients. Moreover, computed tomographic colonography presented good sensitivity, specificity and accuracy for the identification of acromegalic patients with polyps of any size and better results in the diagnosis of large polyps, when they were compared to small polypoid lesions.

Background/Aims: Arthropathy is the most common extraintestinal manifestation observed in patients with Crohn's disease (CD). The present study aimed to screen rheumatoid arthritis (RA) using anti-CCP antibodies and rheumatoid factor (RF) in CD patients from Southern Brazil. Additionally, the presence of arthralgia and spondyloarthritis (SpA) was evaluated. CD patients, previously diagnosed using clinical data, imaging tests, endoscopic and histological findings, were included consecutively. Methods: A total of 100 patients participated in the study, of which 60% were female, with a mean age of 41.9 ± 12.04 (16-83 years). As controls, sera from 100 healthy individuals from the same geographic area were analyzed. Results: Arthralgias were present in 55% of the patients, being more frequent in women (65.5%; 36/55), than in males (34.5%). No association was found between arthralgia and the treatment method used. Six patients (6/100) had SpA previously diagnosed. In the CD group, anti-CCP was positive only in one patient, while RF was positive in 7 patients (7%; 7/100). The anti-CCP positive patient (woman, 38 years old, RF positive), fulfilled the ACR criteria and was diagnosed as RA. In the control group, anti-CCP antibodies were detected in 1% (1/100) and RF was positive in 6 of the samples (6%). Conclusion: Our data showed low frequency of anti-CCP antibodies and RF in Brazilian patients with CD. Additionally, we found a high prevalence of arthralgia in these patients, with 6% of them diagnosed with SpA.

BACKGROUND Crohn’s disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases (IBDs) with a remission-relapsing presentation and symptomatic exacerbations that have detrimental impacts on patient quality of life and are associated with a high cost burden, especially in patients with moderate-to-severe disease. The Real-world Data of Moderate-to-Severe Inflammatory Bowel Disease in Brazil (RISE BR) study was a noninterventional study designed to evaluate disease control, treatment patterns, disease burden and health-related quality of life in patients with moderate-to-severe active IBD. We report findings from the prospective follow-up phase of the RISE BR study in patients with active UC or CD. AIM To describe the 12-mo disease evolution and treatment patterns among patients with active moderate-to-severe IBD in Brazil. METHODS This was a prospective, noninterventional study of adult patients with active Crohn’s disease (CD: Harvey-Bradshaw Index ≥ 8, CD Activity Index ≥ 220), inadequate CD control ( i.e., calprotectin > 200 µg/g or colonoscopy previous results), or active ulcerative colitis (UC: Partial Mayo score ≥ 5). Enrollment occurred in 14 centers from October 2016 to February 2017. The proportion of active IBD patients after 9-12 mo of follow-up, Kaplan-Meier estimates of the time to mild or no activity and a summary of treatment initiation, discontinuation and dose changes were examined. RESULTS The study included 118 CD and 36 UC patients, with mean ± SD ages of 43.3 ± 12.6 and 44.9 ± 16.5 years, respectively. The most frequent drug classes at index were biologics for CD (62.7%) and 5-aminosalicylate derivates for UC patients (91.7%). During follow-up, 65.3% of CD and 86.1% of UC patients initiated a new treatment at least once. Discontinuations/dose changes occurred in 68.1% of CD patients [median 2.0 (IQR: 2-5)] and 94.3% of UC patients [median 4.0 (IQR: 3-7)]. On average, CD and UC patients had 4.4 ± 2.6 and 5.0 ± 3.3 outpatient visits, respectively. The median time to first mild or no activity was 319 (IQR: 239-358) d for CD and 320 (IQR: 288-358) d for UC patients. At 9-12 mo, 22.0% of CD and 20.0% of UC patients had active disease. CONCLUSION Although a marked proportion of active IBD patients achieved disease control within one year, the considerable time to achieve this outcome represents an unmet medical need of the current standard of care in a Brazilian real-world setting.

Tumor necrosis factor alpha (TNFα) has an important role in the body composition of patients with rheumatoid arthritis (RA), Crohn's disease (CD), and spondyloarthritis (SpA). We aimed to assess the nutritional profile of patients with RA, CD, and SpA undergoing remission with multiple therapies comparing to controls and to analyze the effect of anti-TNFα medications in the nutritional parameters of these patients. One hundred thirty-one patients were included: 44 with RA, 43 with CD, and 44 with SpA. Patients receiving anti-TNFα were compared with those receiving non-biological treatment as well as to controls. Nutritional profile included body mass index (BMI), waist circumference (WC), mid-upper arm circumference, and triceps skinfold measurement. Overweight and obesity were highly prevalent on three assessed groups. In patients with RA, BMI was > 25 kg/m in 74.9% patients and 49.2% controls (p < 0.0005); in CD, in 55.7% patients and 41.2% controls (p < 0.0001); and in SpA, in 68.1% patients and 43.5% controls (p < 0.0001). Central obesity was higher in all three disease groups when compared to healthy controls. There was no significant difference on nutritional parameters in patients using or not using anti-TNFα medications, except in patients with SpA, in which biologic therapy was significantly associated with lower BMI and WC, when compared to other therapies. Overweight, obesity, and elevated WC were more prevalent in patients with RA, CD, and SpA undergoing remission when compared to controls despite of used therapy. The use of biologic drugs in patients with SpA was associated with a lower BMI and lower WC.
