ABSTRACT
Context Unspecified Ulcerative Rectocolitis is a chronic disease that affects between 0.5 and 24.5/105 inhabitants in the world. National and international clinical guidelines recommend the use of aminosalicylates (including mesalazine) as first-line therapy for induction of remission of unspecified ulcerative rectocolitis, and recommend the maintenance of these agents after remission is achieved. However, multiple daily doses required for the maintenance of disease remission compromise compliance with treatment, which is very low (between 45% and 65%). Use of mesalazina in granules (2 g sachet) once daily - Pentasa® sachets 2 g - can enhance treatment adherence, reflecting in an improvement in patients' outcomes. Objective To evaluate the evidence on the use of mesalazine for the maintenance of remission in patients with unspecified ulcerative rectocolitis and its effectiveness when taken once versus more than once a day. From an economic standpoint, to analyze the impact of the adoption of this dosage in Brazil's public health system, considering patients' adherence to treatment. Methods A decision tree was developed based on the Clinical Protocol and Therapeutic Guidelines for Ulcerative Colitis, published by the Ministry of Health in the lobby SAS/MS n° 861 of November 4 th, 2002 and on the algorithms published by the Associação Brasileira de Colite Ulcerativa e Doença de Crohn, aiming to get the cost-effectiveness of mesalazine once daily in granules compared with mesalazine twice daily in tablets. Results The use of mesalazine increases the chances of remission induction and maintenance when compared to placebo, and higher doses are associated with greater chance of success without increasing the risk of adverse events. Conclusion The use of a single daily dose in the maintenance of remission is effective and related to higher patient compliance when compared to the multiple daily dose regimens, ...
Contexto A retocolite ulcerativa inespecífica é uma doença crônica que atinge entre 0,5 e 24,5/105 habitantes no mundo. Diretrizes clínicas nacionais e internacionais recomendam o emprego de aminosalicilatos (entre eles, a mesalazina) como terapia de primeira linha na indução da remissão da retocolite ulcerativa inespecífica, com manutenção destes agentes após a remissão. Mas as múltiplas doses diárias necessárias comprometem a adesão ao tratamento, que é muito baixa (entre 45% e 65%). A utilização de mesalazina em grânulos (sachê 2 g) dose única diária - Pentasa® sachê 2 g - pode aumentar a aderência ao tratamento, refletindo numa melhora nos desfechos dos pacientes. Objetivo Avaliar as evidências sobre o uso de mesalazina para a manutenção da remissão em pacientes com retocolite ulcerativa inespecífica e sua eficácia quando tomada uma vez versus mais de uma vez ao dia. Do ponto de vista econômico, avaliar o impacto que a adoção desta posologia teria para o sistema público de saúde do país, comparada ao tratamento padrão atual, considerando a adesão dos pacientes. Métodos Foi elaborada uma árvore de decisão construída a partir do Protocolo Clínico e Diretrizes Terapêuticas de Colite Ulcerativa, publicado pelo Ministério da Saúde na portaria SAS/MS n° 861, de 04 de novembro de 2002, e de algoritmos publicados pela Associação Brasileira de Colite Ulcerativa e Doença de Crohn, objetivando-se obter o custo-efetividade da mesalazina dose única diária em grânulos comparado com mesalazina duas vezes ao dia em comprimidos. Resultados O emprego de mesalazina aumenta as chances de indução da remissão e sua manutenção, quando comparado a ...

AIM: To investigate the effect of mesalazine granules on small intestinal injury induced by naproxen using capsule endoscopy (CE). METHODS: This was a single center, non-randomized, open-label, uncontrolled pilot study, using the PillCam SB CE system with RAPID 5 software. The Lewis Index Score (LIS) for small bowel injury was investigated to evaluate the severity of mucosal injury. Arthropathy patients with at least one month history of daily naproxen use of 1000 mg and proton pump inhibitor co-therapy were screened. Patients with a minimum LIS of 135 were eligible to enter the 4-wk treatment phase of the study. During this treatment period, 3 × 1000 mg/d mesalazine granules were added to ongoing therapies of 1000 mg/d naproxen and 20 mg/d omeprazole. At the end of the 4-wk combined treatment period, a second small bowel CE was performed to re-evaluate the enteropathy according to the LIS results. The primary objective of this study was to assess the mucosal changes after 4 wk of mesalazine treatment. RESULTS: A total of 18 patients (16 females), ranging in age from 46 to 78 years (mean age 60.3 years) were screened, all had been taking 1000 mg/d naproxen for at least one month. Eight patients were excluded from the mesalazine therapeutic phase of the study for the following reasons: the screening CE showed normal small bowel mucosa or only insignificant damages (LIS < 135) in five patients, the screening esophagogastroduodenoscopy revealed gastric ulcer in one patient, capsule technical failure and incomplete CE due to poor small bowel cleanliness in two patients. Ten patients (9 female, mean age 56.2 years) whose initial LIS reached mild and moderate-to-severe enteropathy grades (between 135 and 790 and ≥ 790) entered the 4-wk therapeutic phase and a repeat CE was performed. When comparing the change in LIS from baseline to end of treatment in all patients, a marked decrease was seen (mean LIS: 1236.4 ± 821.9 vs 925.2 ± 543.4, P = 0.271). Moreover, a significant difference between pre- and post-treatment mean total LIS was detected in 7 patients who had moderate-to-severe enteropathy gradings at the inclusion CE (mean LIS: 1615 ± 672 vs 1064 ± 424, P = 0.033). CONCLUSION: According to the small bowel CE evaluation mesalazine granules significantly attenuated mucosal injuries in patients with moderate-to-severe enteropathies induced by naproxen.
