Pouchitis: insight into the pathogenesis and clinical aspects.

Ulcerative colitis (UC) is a chronic intestinal inflammatory disease and familial adenomatous polyposis (FAP) is an autosomal dominant inherited disease. Both diseases, despite being different, may require the same surgical procedure: proctocolectomy with ileal pouch-anal anastomosis (IPAA). The main complication after this procedure is pouch inflammation (pouchitis). This inflammatory complication can affect up to 60 percent of patients who receive IPAA for UC, and a very small percentage of the FAP patients. The purpose of this review was to determine the current molecular mechanisms in its pathogenesis and detail the risk factors involved in pouchitis, its diagnosis, and treatment.

Perfil epidemiológico e análise da efetividade para prevenção de óbitos de pacientes inseridos em protocolo de sepse / Epidemiological profile and effectiveness analysis for the prevention of deaths of patients enrolled in a sepsis protocol

Objetivo: Avaliar casos de sepse e choque séptico verificando perfil epidemiológico, tratamento, adesão às recomendações internacionais e grau de efetividade das intervenções, para analisar sua efetividade na redução da mortalidade. Métodos: Trata-se de estudo observacional transversal com revisão dos atendimentos de sepse e choque séptico entre abril de 2013 e dezembro de 2015. Quanto à efetividade na prevenção de óbitos, o período foi de 2014 a 2015. Resultados: Foram incluídos 412 pacientes (55,3 anos), sendo 58% do sexo masculino. Dentre os pacientes, 80,1% foram inseridos no protocolo no tempo preconizado, 79,9% tiveram coleta de lactato e 91,7% de hemocultura no prazo (p<0,05). Iniciaram antibioticoterapia no prazo 87,4% da amostra. Ocorreram 68 óbitos no pronto-socorro, sendo 80,9% relacionados à sepse. Para a efetividade de prevenção de óbitos, foram incluídos 351 pacientes. O total de prevenção de óbitos foi de 325 pacientes, sendo 52,9% em 2014. O índice de prevenção de óbitos foi crescente (92,6%), indicando alta efetividade. Conclusão: Evidenciou- se alta letalidade nos quadros sépticos. A análise de dados epidemiológicos aponta possíveis melhorias para uniformizar e garantir o melhor atendimento dos pacientes. A adesão e a efetividade do protocolo têm sido crescentes, alcançando índice de prevenção de óbitos muito próximo do ideal. (AU)

Objective: To evaluate cases of sepsis and septic shock checking epidemiological profile, treatment, adherence to the international recommendations, and effectiveness degree of interventions, to analyze the effectiveness in mortality reduction. Methods: This is a cross-sectional observational study with review of sepsis and septic shock between april of 2013 and December of 2015. Regarding effectiveness in preventing deaths, the period was from 2014 to 2015. Results: A total of 412 patients (55.3 years) were included, with 58% male individuals. Of these patients, 80.1% were inserted in the protocol at the recommended time, 79.9% underwent lactate collection, and 91.7% underwent blood culture within the term (p<0.05). Antibiotic therapy was initiated in 87.4% within the term. There were 68 deaths in the emergency room, 80.9% of which were related to sepsis. For the effectiveness of death prevention, 351 patients were included. The total number of prevented deaths was 325 patients, 52.9% in 2014. The death prevention index was increasing (92.6%), indicating high effectiveness. Conclusion: High lethality was observed in septic patients. Epidemiological data analysis points to possible improvement to standardize and guarantee the best care for patients. Protocol compliance and effectiveness have been increasing, reaching an index of deaths prevention very close to the optimal one. (AU)

Intestinal paracoccidioidomycosis resembling Crohn's disease in a teenager: a case report.

BACKGROUND: Differential diagnosis of inflammatory bowel disease is often very challenging. Paracoccidioidomycosis is a fungal disease that can mimic manifestations of Crohn's disease. CASE PRESENTATION: We report a case of a 13-year-old Caucasian boy with abdominal pain for 1.5 years associated with nausea, diarrhea, and weight loss of 10 kg. He presented increased C-reactive protein and an increased erythrocyte sedimentation rate. A colonoscopy showed deep serpiginous ulcers throughout his entire colon and rectum, which suggested Crohn's disease. He received one dose of infliximab, which is an anti-tumor necrosis factor-α, and showed no improvement. After the second dose, he got worse and started to have bloody diarrhea. A new colonoscopy was performed and pathological examination revealed ulcerative chronic inflammation with non-caseating granulomas and fungal structures (budding forms) compatible with Paracoccidioides brasiliensis. He underwent intravenously administered and then orally administered trimethoprim-sulfamethoxazole treatment. Due to drug intolerance, he was treated with amphotericin B and itraconazole, then he showed clinical improvement and mucosal healing with good outcome. CONCLUSION: Paracoccidioidomycosis must be part of the differential diagnosis of inflammatory bowel diseases in endemic areas and must be excluded before starting immunosuppressive therapy.

Ileal pouch of ulcerative colitis and familial adenomatous polyposis patients exhibit modulation of autophagy markers.

Total retocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgery of choice for patients with ulcerative colitis (UC) that are refractory to clinical treatment. Pouchitis is one of the most common complications after this procedure. Defects in autophagy have been reported in inflammatory bowel diseases. However, there are no studies on the IP. Therefore, we studied markers for autophagy in the IP mucosa of UC and FAP patients comparing them to controls with a normal distal ileum. Sixteen patients with IP in "J" shape, asymptomatic and with endoscopically normal IP were evaluated. The control group consisted of eight patients with normal colonoscopy. There was a significant decrease in the transcriptional levels of ATG5, MAP1LC3A and BAX in the FAP group. There was also a decrease in the protein level of Beclin-1 in the UC and FAP compared to the control group. Although the LC3II levels by immunoblot were higher in the UC group, LC3/p62 co-localization were lower in the immunofluorescence analysis in the UC and FAP compared to the control group. Corroborating these results, there was an increase of p62 by immunoblot in the UC group. These findings indicated a modulation of macroautophagy markers in the IP, which may explain the mucosa inflammation predisposition.
