Prevalence and patterns of laxative use in subjects with self-reported constipation: results from a multinational digestive health survey.

Background: Constipation is characterized by symptoms of straining, hard stool, difficult evacuation, and infrequent bowel movements. Online surveys provide valuable information about patients' perspectives, symptoms, management, treatment satisfaction, and risk factors. Methods: This survey explored subject experiences involving 20 gastrointestinal (GI) conditions. In total, 20,099 respondents in seven countries with varied cultural and socioeconomic backgrounds participated. Post hoc analysis of 'self-reported constipation' and related symptoms experienced within the past 6 months and the last episode of constipation provided data on prevalence, demographics, frequency and duration of episodes and related symptoms, impact on quality of life (QoL), management with or without laxatives, and resulting treatment satisfaction. Results: In total, 10,425 subjects reported constipation within 6 months and 2637 at the last episode. Prevalence was highest in females and younger adults. Most subjects reported various coexisting GI symptoms. Almost 80% of 6865 episodes reported by 5337 subjects occurred every 2-3 months to every 2-3 weeks. A higher frequency of constipation correlated with a greater impact on QoL. On a 10-point scale, the mean impact was 6.4. More than 90% of respondents had episodes ranging from 1 day to 1 week. More than 90% took action; 16% used laxatives, of whom 80.3% were satisfied. Conclusion: Constipation, a highly prevalent disorder, spans cultures and socioeconomic classes. Its chronic recurrence has a significant impact on QoL, resulting in symptom self-management in >90% of subjects. Significantly higher satisfaction rates in subjects treated with than without laxatives reflect subjects' reports that self-reported constipation can be treated effectively with laxatives.

Decision tree cnnstruction and cost-effectivenes analysis of treatment of ulceerative colitis with pentasa® mesalazine 2 g sachet / Construcao de arvore de decisao e analise de custo-efetividade do tratamento da retocolite ulcerativa com Pentasa (mesalazina) 2 g sache

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 ...

Long-term weight regain after gastric bypass: a 5-year prospective study.

BACKGROUND: A certain weight gain occurs after obesity surgery compared to the lower weight usually observed between 18 and 24 months postsurgery. The objective of this study was to evaluate weight regain in patients submitted to gastric bypass over a 5-year follow-up period. MATERIALS AND METHODS: A longitudinal prospective study was conducted on 782 obese patients of both genders. Only patients with at least 2 years of surgery were included. The percentage of excess body mass index (BMI) loss at 24, 36, 48, and 60 months postsurgery was compared to the measurements obtained at 18 months after surgery. Surgical therapeutic failure was also evaluated. RESULTS: Percent excess BMI loss was significant up to 18 months postsurgery (p < 0.001), with a mean difference in BMI of 1.06 kg/m2 compared to 12 months postsurgery. Percent BMI loss was no longer significant after 24 months, and weight regain became significant within 48 months after surgery (p < 0.01). Among the patients who presented weight regain, a mean 8% increase was observed within 60 months compared to the lowest weight obtained at 18 months after surgery. The percentage of surgical failure was higher in the superobese group at all times studied, reaching 18.8% at 48 months after surgery. CONCLUSION: Weight regain was observed within 24 months after surgery in approximately 50% of patients. Both weight regain and surgical failure were higher in the superobese group. Studies in regard to metabolic and hormonal mechanisms underlying weight regain might elucidate the causes of this finding.
