- ADALIMUMAB FOR ULCERATIVE COLITIS: RESULTS OF A BRAZILIAN MULTICENTER OBSERVATIONAL STUDY(2017) ZACHARIAS, Patrícia; DAMIÃO, Aderson Omar Mourão Cintra; MORAES, Antonio Carlos; TEIXEIRA, Fábio Vieira; LUDVIG, Juliano Coelho; NONES, Rodrigo Bremer; SAAD-HOSSNE, Rogerio; SASSAKI, Ligia Yukie; SILVA, Rosemary Pereira Lino da; FACCHIN, Luiza; OLANDOSKI, Marcia; KOTZE, Paulo GustavoABSTRACT BACKGROUND: Adalimumab is a monoclonal antibody, tumor necrosis factor-alpha (TNFα) inhibitor that has efficacy for inducing and maintaining remission in moderate-to-severe ulcerative colitis. Real world studies with adalimumab in Latin American ulcerative colitis patients are scarce. OBJECTIVE: To assess the clinical remission rates in induction and maintenance with adalimumab therapy in ulcerative colitis. METHODS: Observational, multicenter and retrospective study on a case series of patients with moderate-to-severe ulcerative colitis under adalimumab therapy. The variables analyzed were: demographic data, previous infliximab status, concomitant drugs, the Montreal Classification, disease activity (Mayo score) at weeks 0, 8, 26 and 52, or until the last follow-up. Clinical remission was defined as a partial Mayo score ≤2 and Last observation carried forward (LOCF) and Non responder imputation (NRI) analysis were used. RESULTS: Thirty-six patients were included in the study. With LOCF analysis, remission rates at weeks 8, 26 e 52 were of 41.7%, 47.2% and 47.2%, respectively. With NRI analysis, remission rates at weeks 8, 26 and 52 were of 41.7%, 41.7% and 27.8%, respectively. CONCLUSION: Adalimumab was effective in the treatment of moderate-to-severe ulcerative colitis. Clinical remission was observed in approximately 40% of the patients at weeks 8 and 26, and in almost a quarter of the patients after 1 year of follow up.
- THE APPROVAL OF VEDOLIZUMAB FOR THE MANAGEMENT OF INFLAMMATORY BOWEL DISEASES IN BRAZIL: the beginning of a new biological era(2016) KOTZE, Paulo Gustavo; DAMIÃO, Aderson Omar Mourão Cintra; MORAES, Antonio Carlos
- VEDOLIZUMAB IN THE MANAGEMENT OF INFLAMMATORY BOWEL DISEASES: A BRAZILIAN OBSERVATIONAL MULTICENTRIC STUDY(2019) PERIN, Ramir Luan; DAMIÃO, Aderson Omar Mourão Cintra; FLORES, Cristina; LUDVIG, Juliano Coelho; MAGRO, Daniéla Oliveira; MIRANDA, Eron Fábio; MORAES, Antonio Carlos de; NONES, Rodrigo Bremer; TEIXEIRA, Fábio Vieira; ZERONCIO, Marco; KOTZE, Paulo GustavoABSTRACT BACKGROUND: There is scarce data regarding efficacy and safety of vedolizumab in inflammatory bowel diseases in Latin America. OBJECTIVE: To describe the first observational real-world experience with vedolizumab in Latin American inflammatory bowel diseases patients. METHODS: Retrospective observational multicentric study of patients with Crohn’s disease (CD) and ulcerative colitis (UC) who used vedolizumab at any phase of their treatment. Clinical remission and response (according to Harvey-Bradshaw index for CD and Mayo score for UC), mucosal healing, need for surgery and adverse events were evaluated. RESULTS: A total of 90 patients were included (52 with CD and 38 with UC), the majority with previous exposure to anti-TNF agents (88.46% in CD and 76.31% in UC). In CD (as observed analysis) remission rates at weeks 12, 26 and 52 were 42.89% (21/49), 61.9% (26/42) and 46.15% (12/26), respectively. In UC, remission rates at weeks 12, 26 and 52 were 28.94% (11/38), 36.66% (11/30) and 41.17% (7/17). Mucosal healing rates were 36.11% in CD and 43.4% in UC. During the study period, 7/52 CD patients underwent major abdominal surgery and 4/38 UC patients needed colectomy. CONCLUSION: Vedolizumab was effective in induction and maintenance of clinical response and remission in CD and UC, with no new safety signs.
- TOFACITINIB IN THE MANAGEMENT OF ULCERATIVE COLITIS REFRACTORY TO ANTI-TNF AND ANTI-INTEGRIN THERAPIES(2018) TEIXEIRA, Fábio Vieira; DAMIÃO, Adérson Omar Mourão Cintra; KOTZE, Paulo GustavoABSTRACT Janus kinases inhibitors have already been incorporated into the management of immune-mediated diseases, such as rheumatoid arthritis, and are being investigated for the treatment of psoriasis and inflammatory bowel diseases, both ulcerative colitis and Crohn’s disease. Tofacitinib is an oral small-molecule drug that inhibits Janus kinases 1, Janus kinases 3, and, to a lesser extent, Janus kinases 2. This inhibition ends up blocking signals for several inflammatory cytokines that are involved in the pathogenesis of inflammatory bowel diseases and play a role in many immune signaling routes, including lymphocyte activation, function, and proliferation. We report a patient with active ulcerative colitis with primary non-response to three biologics (infliximab, adalimumab and vedolizumab), with different mechanisms of action, who refused surgical treatment and had a favorable response to tofacitinib with clinical and endoscopic remission. No adverse events were observed with the use of the agent. This case illustrates the difficulties we may face regarding the identification of the expression of proper mechanism of action involved in the pathogenesis of ulcerative colitis patients and the importance of having another treatment option with different mechanism of action, like tofacitinib.

- HEALTH-RELATED QUALITY OF LIFE IN ADOLESCENTS AND YOUNG ADULTS WITH INFLAMMATORY BOWEL DISEASE IS ASSOCIATED WITH REDUCTION IN SCHOOL AND WORK PRODUCTIVITY RATHER THAN PHYSICAL IMPAIRMENT: A MULTIDISCIPLINARY STUDY(2021) OBA, Jane; SOBRADO, Carlos W; DAMIÃO, Aderson O M C; AZEVEDO, Matheus; CARLOS, Alexandre; QUEIROZ, Natália; LEN, Claudio A; TOMA, Ricardo K; DEBONI, Mariana; OZAKI, Marcos J; CARRILHO, Flair José; NAHAS, Sergio; SILVA, Clovis AABSTRACT BACKGROUND: Inflammatory bowel diseases (IBD), comprising Crohn’s disease and ulcerative colitis, are chronic inflammatory diseases of the gastrointestinal tract that often have their onset among adolescents and young adults (AYA). IBD are characterized by episodes of active disease interspersed with periods of remission, and its activity is inversely correlated with health-related quality of life (HRQL). OBJECTIVE: This study aimed to determine whether AYA in remission or with low IBD activity would exhibit HRQL similar to that of age-matched healthy individuals, and whether demographic and disease factors could affect HRQL using a ‘patient-reported outcome’ instrument. METHODS: This study enrolled only AYA with IBD, with low activity. This research included five multidisciplinary clinics of two academic hospitals: Paediatric Gastroenterology, Gastroenterology, Coloproctology, Paediatric Rheumatology and Adolescent divisions, São Paulo, Brazil. A total of 59 AYA with IBD (age, 13-25 years) and 60 healthy AYA (age, 13-25 years) completed the Pediatric Quality of Life Inventory 4.0 and 36-Item Short-Form Health Survey questionnaires and the visual analogue scale (VAS) for pain. Demographic data, extra-intestinal manifestations, treatment, and outcomes regarding CD and UC were evaluated. RESULTS: AYA with IBD and healthy controls were similar with respect to median ages (18.63 [13.14-25.80] years vs 20.5 [13.68-25.84] years, P=0.598), proportion of female sex (42% vs 38%, P=0.654), and percentage of upper middle/middle Brazilian socioeconomic classes (94% vs 97%, P=0.596). The school/work score was significantly lower in AYA with IBD than in healthy controls (70 [10-100] vs 75 [5-100], P=0.037). The ‘general health-perception’ score was significantly lower in AYA with IBD than in healthy controls (50 [10-80] vs 0 [25-90], P=0.0002). The median VAS, FACES pain rating scale, and total VAS scores were similar between the two groups (2 [0-10] vs 3 [0-9], P=0.214). No association between HRQL and clinical and demographic parameters was identified among IBD patients. CONCLUSION: AYA with low IBD activity reported poor HRQL in school/work and general health perception domains, which highlights a disability criterion in this vulnerable population.
- BIOLOGICAL THERAPY PENETRATION FOR INFLAMMATORY BOWEL DISEASE IN LATIN AMERICA: CURRENT STATUS AND FUTURE CHALLENGES(2019) QUARESMA, Abel Botelho; COY, Claudio Saddy Rodrigues; DAMIÃO, Aderson Omar Mourão Cintra; KAPLAN, Gilaad G; KOTZE, Paulo GustavoABSTRACT 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.
