Abstract Objective To evaluate the relapse rate after discontinuation of biological therapy in patients with Crohn's disease treated at the University Hospital. Methods This is a series of 9 cases of CD patients who used long-term immunobiologicals. Non-randomized sample, followed for 1 year, prospectively. Results Nine patients were studied, 8 females, with an average age of 43.8 years, and non-smokers. The average time of use of the immunobiological for suspension was 6.77 years, with 66.66% of them having been in use for more than 5 years. The mean initial CDAI was 25. After 6 months of follow-up, CRP was less than 10 mg/L in 88.8% of them. Only 3 patients measured the Calprotectin, low. (10, 15 and 30 mcg/g). The ESR averaged 15.77 mm/h. In 66.6% of those studied, the 6-month colonoscopy was normal - mayo 0. In the 1-year follow-up, 3 patients underwent CT, normal. At 1-year colonoscopy of 3 patients, there was endoscopic recurrence in 2. The mean CDAI after the first year was 38.11. The mean ESR was 17.11 mm/h. The worst outcomes occurred in 2 (20%) patients, both Montreal A3L3B2, with clinical and endoscopic recurrence. The same previous immunobiological was reintroduced, with excellent clinical response. Conclusion Individualized analysis of the course of the disease proves to be the best way for adequate clinical monitoring during its use, optimization of the therapeutic regimen, and the possibility of interruption.

ABSTRACT Objectives: To assess the quality of life of patients diagnosed with inflammatory bowel disease (IBD) using immunobiological therapy and to relate the general and domain scores of the Inflammatory Bowel Disease Questionnaire (IBDQ) to the immunobiological drug in use and the clinical and sociodemographic variables. Methods: This was a descriptive observational cross-sectional study, conducted from June to September 2018 in a tertiary hospital in Sergipe, which included 47 patients with a diagnosis of Crohn's disease. The IBDQ questionnaire was applied together with a sociodemographic questionnaire, and the clinical data and the history of the disease were analyzed. Results: Female, mixed-race, married patients from the countryside of the state of Sergipe, Brazil, who had never undergone any intestinal surgery, represented most of the study participants. 24 patients were on infliximab and 23 were on adalimumab. Variables such as gender, type of immunobiological drug and duration of its use, and association of therapy with other medications were shown to statistically significantly influence the report quality of life (p-value < 0.05). Conclusion: Further studies with larger samples are necessary to allow a more accurate delimitation of the impact of clinical and sociodemographic variables on the quality of life of patients with inflammatory bowel disease.

RESUMEN Objectivos: Avaliar a qualidade de vida de pacientes diagnosticados com doença inflamatória intestinal (DII) em uso de terapia imunobiológica e relacionar o escore geral e por domínios do “Inflammatory Bowel Disease Questionnaire” (IBDQ) com o imunobiológico em uso e as variáveis clínicas e sociodemográficas. Métodos: Estudo observacional descritivo analítico transversal, realizado no período de junho a setembro de 2018, em hospital terciário de Sergipe, que incluiu 47 pacientes com diagnóstico de Doença de Crohn. Foi aplicado o questionário IBDQ, associado a um questionário sociodemográfico e analisados os dados clínicos e da história da doença. Resultados: Pacientes do sexo feminino, pardos, casados, procedentes do interior de Sergipe e que nunca foram submetidos a nenhuma cirurgia intestinal representaram a maioria dos participantes do estudo. 24 pacientes estavam em uso de Infliximabe e 23 em uso de Adalimumabe. Variáveis como o gênero, tipo de imunobiológico e duração de seu uso e associação da terapêutica com outras medicações mostraram influenciar a qualidade de vida relatada, com significância estatística (p-valor < 0,05). Conclusão: Novos estudos com amostras maiores são necessários para que se possa permitir uma delimitação mais acurada do impacto de variáveis clínicas e sociodemográficas na qualidade de vida dos pacientes com doença inflamatória intestinal.

Development of polymeric materials has been increasingly emphasized in Biomedicine. Here, we evaluate the use of microcapsules made of Biodritin®, a biocompatible polymer compound which contains sodium alginic acid, a natural polymer extracted from algae, and Cis-Chondroitin sulfate, a glycosaminoglycan from the extracellular matrix. Gelation of this polymer into microcapsules is achieved by dropping the compound into BaCl2 or CaCl2 gelling solutions. A functional microcapsule is dependent on its permeability, mechanical stability, immunoisolation capacity and biocompatibility. The mechanical stability of Biodritin-barium and Biodritin-calcium microcapsules was investigated after rotational stress upon in vitro culture and in vivo implantation. Viability studies of encapsulated cells were also performed to assess other functional parameters of the microcapsules. When subject to rotational stress, Biodritin-barium microcapsules exhibited breaks, whereas the Biodritin-calcium microcapsules did not. Both kinds of Biodritin® microcapsules proved to be mechanically resistant in in vitro and in vivo studies. However, the Biodritin-calcium material was found to be more elastic while the Biodritin-barium microcapsules displayed a more plastic behavior. These properties seem to be determinant for viability of the encapsulated cell’s, since the Biodritin-calcium microcapsules presented more viable cells than the Biodritin-barium microcapsules.
