Introdução: O envolvimento gastroduodenal pode ocorrer na doença de Crohn (DC). Seu diagnóstico histológico definitivo é habitualmente realizado através da demonstração do granuloma não caseoso. O achado de gastrite focal H. pylori negativa em biopsias gástricas de pacientes com DC ileal e/ou colônica, apesar de não ser específico, também sugere o envolvimento da doença neste segmento. Objetivos: avaliar a frequência da gastrite focal em pacientes com DC comparada à de pacientes com retocolite ulcerativa (RCU) e controles, assim como as frequências da infecção pelo H. pylori nessas populações e correlacioná-las com a presença de gastrite focal; avaliar a capacidade da imunohistoquímica em diferenciar a gastrite focal nos três grupos; avaliar as associações entre dados demográficos, aspectos clínicos, laboratoriais, uso de medicamentos, presença de sintomas do trato gastrintestinal (TGI) superior e achados endoscópicos com presença de gastrite focal em pacientes com doença inflamatória intestinal (DII); e avaliar a associação entre uso de medicamentos nesses pacientes e infecção pelo H. pylori. Métodos: Foram estudados 62 pacientes com DC, 35 pacientes com RCU e 40 pacientes controles. Todos foram submetidos à endoscopia digestiva alta (EDA) com biopsias para o teste da urease, exame histológico e imunohistoquímico. Resultados: Dos 137 pacientes estudados foram excluídos dois pacientes com DC e um com RCU. Não houve diferença estatisticamente significante entre os grupos com relação à idade (p=0,921) e sexo (p=0,192). A maioria dos pacientes com DC estava em remissão clínica (75%). Cerca de 80% dos pacientes com DC faziam uso de azatioprina. H. pylori foi positivo em 18/60 (30%) pacientes com DC, 12/34 (35%) na RCU e 20/40 (50%) no grupo controle sem diferença estatisticamente significante entre os grupos (p=0,131). Não foram observadas associações estatisticamente significantes entre uso de medicamentos e infecção pelo H. pylori nos pacientes com DII. A gastrite focal H. pylori negativa foi diagnosticada em 7/42 (16,7%) na DC, 3/22 (13,6%) na RCU e 2/20 (10%) no grupo controle, sem diferença estatisticamente significante entre eles (p=0,919). A gastrite focal H. pylori positiva foi diagnosticada em 2/18 (11%) na DC, 3/12 (25%) na RCU e 7/20 (35%) no grupo controle, sem diferença estatisticamente significante (p=0,213). Não foram observadas associações estatisticamente significantes entre características clínicas, laboratoriais, uso de medicamentos, sintomas do TGI superior, achados endoscópicos e gastrite focal. No entanto, foi observado que o uso de azatioprina nos pacientes com DC H. pylori negativos apresentou uma tendência a reduzir a gastrite focal. A imunohistoquímica da gastrite focal dos pacientes com DC e RCU H. pylori negativos foi semelhante e diferiu do grupo controle por este apresentar um maior acúmulo de linfócitos B (CD20). Já a imunohistoquímica da gastrite focal dos pacientes com DC, RCU e controles H. pylori positivos foi indistinguível. Conclusões: Pacientes com DII tendem a ser menos infectados pela bactéria H. pylori. A frequência de gastrite focal H. pylori negativa diagnosticada em nosso estudo foi menor do que a descrita na literatura. O uso de imunossupressor (azatioprina) pode estar relacionado com tal achado / Introduction: Gastroduodenal involvement may occur in Crohns disease (CD). Definitive histological diagnosis of CD in the upper gastrointestinal (GI) tract normally relies on the demonstration of epitheloid granuloma which is considered the histological hallmark of gastric CD. If granulomas are absent, the description of focally enhanced gastritis (FEG) or focal active gastritis in gastric biopsies of patients with known ileal and/or colonic CD, although not exclusive to CD, suggests the involvement of the disease at this site. Objectives: To access the prevalence of FEG in CD patients compared with a group of ulcerative colitis (UC) and CD/UC-free controls, as well as the frequencies of H. pylori infection in those population and correlate them to the presence of FEG; evaluate the capacity of immunohistochemistry in differentiating FEG in the three groups; evaluate the correlation with demographic and clinical characteristics, laboratory findings, current medical therapy as well as the presence of forgut symptoms and mucosal lesions at endoscopy with the presence or absence of FEG in patients with inflammatory bowel disease (IBD) and evaluate the association between medical therapy and H. pylori infection in IBD patients. Methods: We studied 62 patients with CD, 35 patients with UC and 40 patients from control group. All underwent upper GI endoscopy. Biopsy specimens taken from angulus, antrum and gastric body were evaluated by urease test, histology and immunohistochemistry. Results: Of the 137 patients studied we excluded 2 patients with CD and 1 with UC. There was no statistically significant difference among the groups in terms of age (p=0.921) and gender (p=0.192). The majority of CD patients were in clinical remission (75%). Around 80% of CD patients were taking azathioprine. H. pylori was positive in 18/60 (30%) CD patients, in 12/34 (35%) UC and in 20/40 (50%) controls with no statistically significance difference among the groups (p=0.131). No association was found between use of medications and H. pylori infection in IBD patients. In H. pylori negative patients, FEG was diagnosed in 16.7% cases (7/42) of CD, compared with 13.6% (3/22) of UC patients and 10% (2/20) of controls, with no statistically significance difference among them (p=0.919). In H.pylori positive patients, FEG was diagnosed in 11% cases (2/18) of DC, 25% (3/12) in UC and 35% (7/20) of controls with no significant difference among them (p=0.213). There was no statistical interrelationship between FEG and demographic and clinical characteristics, laboratory findings, use of medications, upper GI symptoms and endoscopic findings. However, it was observed that use of azathioprine in H. pylori negative CD patients presented a tendency to reduce FEG. In H. pylori negative patients, immunohistochemistry of FEG of CD and UC was similar and differed from controls as it presented a higher accumulation of B lymphocytes (CD20). On the other hand in H. pylori positive IBD patients, immunohistochemistry of FEG was indistinguishable from controls. Conclusions: IBD patients tend to be less infected by H. pylori. The frequency of H. pylori negative FEG diagnosed in our study was lower than described in literature. The use of immunossupressants (azathioprine) may be related to such findings

A proctocolectomia total com anastomose de reservatório ileal ao canal anal revolucionou a terapêutica cirúrgica da RCU tornando-se a operação de escolha, principalmente no adulto jovem, pois promove a retirada de toda a doença e permite a conservação esfincteriana. Após cerca de duas décadas de experiência com esta operação, cujos trabalhos iniciais preocupavam-se, sobretudo, com sua técnica e complicações, as atenções concentram-se atualmente no estudo da qualidade de vida de doentes submetidos à proctocolectomia com anastomose de reservatório ileal ao canal anal avaliando parâmetros sistêmicos, emocionais e sociais que possam interferir no cotidiano desses doentes. Para estudar a qualidade de vida após a operação, utiliza-se o Questionário de Doenças Inflamatórias Intestinais (IBDQ), pois apresenta boa reprodutibilidade, reflete as alterações importantes que ocorrem no estado de saúde dos doentes com Doença Inflamatória Intestinal, podendo ser plenamente utilizado para averiguação do impacto, eficácia e eficiência de medidas terapêuticas e, além disso, foi recentemente traduzido e validado para a língua portuguesa. Não conhecemos estudos nacionais (base de dados PUBMED) que avaliem a qualidade de vida destes doentes, operados há mais de dez anos. Por esta razão, decidimos empreender o atual estudo, empregando a mesma metodologia utilizada em dissertação de mestrado apresentada e aprovada no Departamento de Gastroenterologia da FMUSP e publicado posteriormente, agora com o IBDQ devidamente validado para o Brasil. O estudo é formado por 36 doentes portadores de retocolite ulcerativa (RCU) submetidos à proctocolectomia com conservação esfincteriana e anastomose de bolsa ileal em J ao canal anal operados há mais de 10 anos. Os doentes foram atendidos no Ambulatório do Serviço de Cirurgia do Cólon e Reto da Divisão de Clínica Cirúrgica II do HCFMUSP a partir de 1985. Após aplicação do IBDQ, verificou-se que a qualidade de vida foi excelente em nove doentes (25%), boa em 11 (30,6%), regular em 13 (%36,1) e má em três (8,3%). Comparando a classificação do IBDQ com o sexo notou-se um predomínio de bons resultados no sexo masculino em detrimento do feminino. Ao compararmos a classificação com a idade percebeu-se que os maus resultados tiveram maior associação com idade avançada. Houve diferença de qualidade de vida quando comparamos os domínios, sendo que os sintomas intestinais comparados aos sistêmicos e sistêmicos aos aspectos sociais apresentaram diferença significante. No domínio sintomas intestinais encontrou-se menor pontuação para diarréia e maior para sangramento retal. Ao analisarmos as questões do domínio sintomas sistêmicos, notou-se que uma adequada noite de sono, sem ter que acordar devido ao problema intestinal, foi a que obteve a menor pontuação, inclusive a menor em todo o IBDQ. Por outro lado, disposição física obteve a maior pontuação. No domínio aspectos sociais, lugares sem banheiro e compromisso social obtiveram, respectivamente, a menor e maior pontuação. Finalmente, no domínio aspecto emocional, irritado e satisfeito e agradecido com sua vida pessoal obteve, respectivamente, a menor e maior pontuação. Além disso, esta última questão obteve a maior pontuação em todo o questionário. Em nosso estudo pudemos determinar qualidade de vida adequada e satisfatória após 10 anos, similar a encontrada na literatura; 85% dos doentes estavam satisfeitos e agradecidos com a operação realizada. A qualidade de vida excelente ou boa em 55,6% dos doentes foi menor do que anteriormente encontrado na FMUSP, o que talvez possa ser explicado pela expectativa pessoal almejada individualmente, inadequado esclarecimento sobre expectativas excessivamente otimistas e permanência ou incremento da dependência medicamentosa anteriormente utilizada. Neste estudo, verificou-se que os domínios intestinal e social foram, possivelmente, os que mais influenciaram os resultados no questionário de qualidade de vida. Além disso, o domínio sistêmico foi o que apresentou menor peso na pontuação final do IBDQ em ambos os estudos. O elevado índice de satisfação obtido com esses resultados demonstra que a bolsa ileal permanece como operação adequada e com resultados aceitáveis, inclusive demonstrado pela questão que apresentou maior pontuação no IBDQ. Conclui-se, portanto, que a possibilidade de conservação esfincteriana deve ser sempre aventada, visto que os doentes permanecem clinicamente estáveis e com elevada qualidade de vida mesmo após longos períodos / Proctocolectomy with ileal pouch-anal anastomosis has revolutionized the surgical therapy of ulcerative colitis patients, making it the operation of choice, especially for the young adults for it completely removes the disease and allows the sphincter preservation. After about 20 years of experimenting with this operation, which initial work was concerned with, above all, its techniques and complications, currently has its attention focused on the study of the quality of life of patients submitted to proctocolectomy with ileal pouch-anal anastomosis, evaluating systemic, emotional and social parameters which may influence in the day-to-day life of these patients. To study the quality of life after the surgery, the Inflammatory Bowel Disease Questionnaire (IBDQ) was used since it presents reproducibility, reflects the important alterations which occur in the health condition of Inflammatory Bowel Disease patients and it can be thoroughly used to evaluate the impact, effectiveness and efficiency of the therapeutical measures, especially now, since it has been translated and validated to the Portuguese language. We are not aware of any national studies (PUBMED databasis) that evaluate the quality of life of patients who have been operated on over 10 years ago. For this reason, we decided to set this study out, employing the same methodology used in a Masters Dissertation presented and approved by the Gastroenterology Department at FMUSP which was later published, now with the IBDQ validated in Brazil. The study comprises of 36 Inflammatory Bowel Disease (IBD) patients submitted to proctocolectomy with sphincter preservation using the J pouch reconstruction who have been operated on over ten years ago. These patients have been taken care at the Rectum and Colon Surgery Ambulatory Services of the Second Surgical Clinic Division of HCFMUSP as of 1985. After applying the IBDQ, it was verified that the quality of life was excellent for 9 patients (25%), good for 11 patients (30,6%), regular for 13 patients (36,1%) and bad for 3 patients (8,3%). Comparing the IBDQ classification to gender, it was noticed that the best results occurred to males in detriment to females. Upon comparing the classification to age, it was verified that the worse the results were associated to the older patients. There has been a notable difference in the quality of life when domains where compared, being these domains the intestinal symptoms compared to the systemic symptoms and the latter to the social aspects. In the realm of intestinal symptoms, a lower score for diarrhea whereas a greater one for rectum bleeding was observed. Upon analyzing the issues in the realm of systemic symptoms, it was acknowledged that a good night of sleep, without having to get up due to the intestinal problem, was the issue with the lowest score, as a matter of fact; it was the lowest score in the whole IBDQ. On the other hand, physical disposition scored the highest. In the social aspects realm, places deprived of restrooms and social appointments scored, respectively, the lowest and highest score. Finally, in the realm of emotional aspects, irritated and satisfied and pleased with his/her life scored, correspondingly, the lowest and highest score. Furthermore, the latter has scored the highest in the whole questionnaire. In our study, we could determine an adequate and satisfactory quality of life 10 years later, similar to the one found in literature; 85% of the patients were happy and satisfied having undergone the surgery. An excellent or good quality of life for 55,6% of the patients was lower than the one found previously at FMUSP, which may be explained by the individually desired personal expectation, inadequate information on excessively optimistic expectations, and the remain or increment of previously used drug dependency. It could be observed in this study that the intestinal realm and the social realm were, possibly, the aspects which were most influential in the results of the quality of life questionnaire. Moreover, the systemic realm was the least influential in the final IBDQ score in both studies. The high level of satisfaction obtained from these results shows that the ileal pouch remain the adequate surgery with acceptable results, corroborated by the highest score result question of the IBDQ. We can conclude, therefore, that the possibility of the sphincter preservation must be always taken into account since patients remain clinically stable and have a high quality of life even after long periods

Colite ulcerativa afeta exclusivamente o cólon e o reto, possui etiologia ainda pouco conhecida podendo estar relacionada com fatores ambientais, genéticos e de resposta imune. O tratamento se baseia em medicamentos como aminossalicilatos, glicocorticóides e imunossupressores, porém seus efeitos colaterais atrapalham a adesão do paciente ao tratamento por longos períodos. Condroitim sulfato (CS) e glucosamina (GlcN) são atualmente indicados para o tratamento de doenças inflamatórias, como a osteoartrite, principalmente por apresentarem efeito anti-inflamatório ao diminuírem a ação do fator de transcrição NF-kB diminuindo a expressão de metaloproteases (MMP), TNF-α, iNOS entre outros mediadores inflamatórios. O objetivo deste trabalho foi analisar os efeitos da associação de CS e GlcN na colite ulcerativa experimental induzida por dextran sulfato de sódio (DSS) em ratos Wistar. Para isso foram avaliados o índice de atividade da doença (IAD), parâmetros hematológicos e bioquímicos, morfológicos e a atividade de MMP-2 e -9 da matriz extracelular no intestino grosso, concentração de NO tecidual e concentração de glicosaminoglicanos. Os animais foram divididos em quatro grupos: (1) controle, (2) controle + CS/GlcN, (3) DSS , (4) DSS + CS/GlcN. Observamos que o tratamento com CS/GlcN melhorou a severidade da colite aguda em ratos, verificado pela redução do score histológico e melhora de parâmetros hematológicos. CS/GlcN também reduziu a destruição de células caliciformes observados pelo azul de alcian, bem como a produção de óxido nítrico, a atividade de mieloperoxidase e metaloproteases, principalmente de MMP-9. Além disso, foi observado uma redução na concentração de GAGs total no grupo DSS + CS/GlcN quando comparado ao grupo DSS. Portanto, a administração de CS/GlcN apresentou melhoras em alguns dos parâmetros avaliados principalmente na atividade de MMP-9, mostrando um potencial destes compostos para futura utilização no tratamento dessa patologia. / Inflammatory bowel disease, including ulcerative colitis and Crohn's disease comprising a broad spectrum of diseases those have in common chronic inflammation of the gastrointestinal tract. Ulcerative colitis affects only the colon and rectum, has still poorly understood etiology and this could may be related to environmental factors, genetic and immune response. Treatment is based on drugs as aminosalicylates, immunosuppressants and glucocorticoids, but its side effects hinder patient compliance with treatment for long periods. Chondroitin sulphate (CS) and glucosamine (GlcN) are currently indicated for treatment of inflammatory diseases such as osteoarthritis, mainly because of the anti-inflammatory effect by decreasing the activity of transcription factor NF-kB and decreasing the expression of metalloproteases (MMP), TNF-α, iNOS and other inflammatory mediators. The objective of this study was to analyze the effects of the combination of CS and GlcN in experimental ulcerative colitis model induced by dextran sulfate sodium (DSS) in rats. To do so we evaluated the disease activity index (DAI), haematological and biochemical parameters, morphological changes and activity of MMP-2 and -9, NO and glycosaminoglycans concentration in the large intestine. Animals were divided into four groups: (1) control, (2) control + CS / GlcN, (3) DSS-induced colitis, (4) DSS + CS / GlcN. We observed that treatment with CS/GlcN improved the severity of acute colitis in rats verified by histological score reduction and improvement in hematological parameters. CS/GlcN also reduced goblet cells destruction observed by alcian blue, as well as nitric oxide production, the activity of myeloperoxidase and metalloproteases, especially MMP-9. Moreover, we observed a reduction in the concentration of total GAG + DSS group CS / GlcN when compared to DSS. Therefore, administration of CS/GlcN showed improvements in some of the parameters evaluated mainly on the activity of MMP-9, showing a potential future use of these compounds for the treatment of this pathology.

Bakgrund: Crohns sjukdom och ulcerös kolit är kroniska, inflammatoriska tarmsjukdomar som under de senaste decennierna har ökat påtagligt. De kan drabba människor i alla åldrar och ha en negativ påverkan på patienternas livskvalitet. Sjuksköterskan har en viktig roll i att se till att patienterna får tillräckligt med information och stöd för att klara av att sköta sin egenvård. Syfte: Syftet var att belysa hur patienter med Crohns sjukdom och ulcerös kolit upplevde symtomens påverkan i det dagliga livet och hur de anpassat sin tillvaro efter sjukdomen. Metod: En litteraturöversikt grundad på elva vårdvetenskapliga studier med kvalitativ design genomfördes. Studierna analyserades utifrån det valda syftet och nyckelfynd sammanställdes under två huvudteman. Resultat: Litteraturöversikten belyste hur deltagarna upplevde sjukdomarnas symtom och vilken påverkan de hade på det vardagliga livet. Här beskrevs påverkan på familjeliv, relationer, sociala sammanhang och arbetsliv. Sammanfattande utgjorde sjukdomarna ett hinder. Vidare beskrevs sjukdomarnas emotionella påverkan och hur deltagarna upplevde att de led av en osynlig sjukdom. Avslutningsvis visas vilka attityder deltagarna hade mot livet, vilka strategier som använts för att hantera sjukdomen och att acceptans av sjukdomen var viktig för att lära sig att leva med den. Diskussion: Resultatfynden har diskuterats utifrån Callista Roys adaptionsmodell och kopplats till andra vetenskapliga studier. Livet med en kronisk sjukdom innebär ständiga förändringar och sjuksköterskan kan genom att identifiera faktorer som påverkar adaptionen hjälpa patienten att uppnå balans. / Background: Crohn's disease and ulcerative colitis are chronic inflammatory bowel diseases that have increased significantly in recent decades. The diseases can debut at all ages, and they have a negative effect on the patients´ quality of life. A nurse has an important part of ensuring that patients receive sufficient information and support to manage their self-care. Aim: The purpose was to illuminate how patients with Crohn's disease and ulcerative colitis experienced the effects of the symptoms in their daily lives and how they adapted to the disease. Method: A literature review based on eleven nursing studies with qualitative design was conducted. The studies were analyzed based on the chosen purpose and key findings were compiled under two main themes. Results: The literature review illustrated how the participants experienced the symptoms of the disease and what impact they had on everyday life. The impact on family life, relationships, social contexts and working life were described. In summary, the disease was an obstacle. The emotional impact of the disease and how the participants perceived that they suffered from an invisible disease were described. Finally, what attitudes the participants had towards life, what strategies were used to manage the disease, and that acceptance of the disease was important for learning to handle it. Discussion: The findings have been discussed based on Callista Roys adaptation model and linked to other scientific studies. Life with a chronic disease involves constant changes, and the nurse can help the patient to achieve balance by identifying factors that affect the adaptation.

A diferença entre as duas éa sua localização, sendo a RCU específica da região do cólon e reto. O tratamento atual para estas patologias é realizado a base de corticosteróides, imunomoduladores ou anti -TNF-a, conhecido como terapia biol ógica, os quais apresentam diversos efeitos colaterais ao paciente. A patogênese desta doença está relacionada com fatores gen éticos, imunol ógicos e ambientais. Acredita-se que o desequilíbrio da microbiota, assim como a ruptura na barreira natural exercida pela mucosa intestinal seja o primeiro passo para o desencadeamento da resposta inflamatória. As fibras alimentares apresentam função sobre a modulação da microbiota, sendo utilizada como substrato para a formação de ácidos graxos de cadeia curta (AGCC), gerados por meio do processo de fermentação. Em adição, os compostos fenólicos presentes nos alimentos apresentam atividade antioxidante e anti -inflamatória que podem atuar na modulação do processo inflamatório. Sendo assim, o objetivo deste trabalho foi avaliar a utilização de um subproduto da indústria de alimentos, a casca do maracujá, como fonte de fibras e compostos fenólicos, na alimentação de ratos com colite induzida por TNBS e sua influência no processo inflamatório. Ratos Wistar foram alimentados com dieta AIN-93, sendo substituídos 50% da celulose da dieta padrão (AIN) por fibras da casca do maracujá (PFF), em dois ensaios biológicos: prevenção e tratamento. O dano causado àmucosa foi avaliado macro e microscopicamente, assim como a expressão de marcadores inflamatórios. Avaliação da microbiota e formação de AGCC foram realizadas no conteúdo cecal. Embora a avaliação macroscópica da mucosa tenha apresentado um escore maior para o grupo PFF no ensaio prevenção, a avaliação microscópica em ambos os ensaios não mostrou diferença no dano àmucosa entre os grupos. O ensaio tratamento mostrou diminuição da peroxidação lipídica do cólon, diminuição na contagem de enterobactérias e aeróbios totais, assim como aumento de ácido acético e butírico nas fezes do grupo PFF. Jáno ensaio prevenção foi observada modulação dos lactobacilos e bifidobactérias. Com relação aos marcadores inflamatórios, foram observadas modulações significativas da expressão de IKK?, COX-2 e iNOS nos animais alimentados com a dieta PFF. Estes resultados sugerem que a casca do maracujá Passiflora edulis pode modular a microbiota aumentando a produção de AGCC, assim como a expressão de marcadores inflamatórios observados na colite induzida por TNBS. Desta forma, a casca do maracujá poderia ser utilizada como coadjuvante na terapêutica da DII como fonte de fibras e polifenóis / Abstract: Inflammatory bowel disease (IBD) is a chronic relapsing disease that affects millions of people worldwide, encompassing Crohn's disease (CD) and ulcerative colitis (UC). UC is an inflammation specific to the region of the colon and rectum. Current treatments for these diseases are based on the use of corticosteroids, immunomodulators or biological therapy, which have various side effects to the patient. The pathogenesis of IBD is related to genetic, immunological and environmental factors. It is believed that the microbial imbalance as well as natural break in the barrier exerted by the intestinal mucosa is the first step in triggering the inflammatory response. Food dietary fiber presents capacity to modulate the microbiota and improve short chain fatty acids (SCFA) formation, by fermentation process. In addition, the phenolic compounds present in the food have antioxidant and anti-inflammatory activities that can modulate the inflammatory process. Thus, this study aimed to evaluate the use of a byproduct of the food industry, the passion fruit peel, as a source of fiber and phenolic compounds in the diet of rats with TNBS-induced colitis and its influence on the inflammatory process. Wistar rats were fed a modified AIN-93 (50% of cellulose was replaced by passion fruit peel PFF) to evaluate prevention and treatment of colitis induced by TNBS. The damage to the mucosa was evaluated macroscopically and microscopically, as well as the expression of inflammatory markers. Evaluation of the microbiota and formation of SCFA in cecal contents were performed. The macroscopic appearance of the mucosa damage in the group PFF was higher than AIN in prevention trial. However, the microscopic evaluation in both trials showed no difference in mucosal damage amongst the groups. Treatment trial showed that PFF could promote a decrease in lipid peroxidation of the colon, decrease in enterobacteria and total aerobics counts, as well as increase in acetic and butyric acid in the stool. On the other hand, the prevention trial showed that the ingredient could exert modulation on lactobacilli and bifidobacteria. The inflammatory markers showed significant modulation, mainly IKK?, COX-2 and iNOS in animals fed with PFF diet. These results suggest that the passion fruit peel, Passiflora edulis, can modulate the microbiota, increase the production of SCFA, and modulate the expression of inflammatory markers observed in TNBS-induced colitis. Passion fruit peel could be used in the treatment of IBD as a source of fiber and polyphenols / Doutorado / Nutrição Experimental e de Alimentos / Doutora em Alimentos e Nutrição

Bakgrund: Inflammatorisk tarmsjukdom (IBD) är samlingsnamn för kroniska mag-och tarmsjukdomar och innefattar Crohns sjukdom (CD) samt Ulcerös kolit (UK). Båda sjukdomar löper i skov med återkommande, långvariga diarréer med förbättrings-och försämringsperioder och kan relateras till fysiska, psykiska samt sociala faktorer. Då uppenbara orsaker eller symtom ej finns är det på många sätt en dold sjukdom och kan skapa otillräcklig förståelse för patientens specifika behov. För att patienten ska få rätt stöd i hanteringen av sjukdomen samt få en god omvårdnad, bör sjuksköterskan att ha gott bemötande, tillräcklig kunskap där vården ges på ett personcentrerat, evidensbaserat sätt. Syfte: Syftet var att beskriva patienters upplevelse av att leva med inflammatorisk tarmsjukdom, IBD. Metod: En litteraturöversikt valdes som metod och baserades på tio kvalitativa artiklar. Databassökningar gjordes från CINAHL Complete och Medline with full text. Artiklarna analyserades enligt Fribergs fem steg. Resultat: I resultatet framkom sex teman utifrån patienternas upplevelse; påverkan av IBD på självbilden, påverkan av IBD i relationer och sociala sammanhang, patienters upplevelse av hälso- och sjukvården, känslomässig påverkan, utveckling och acceptans samt påverkan av IBD i arbetslivet. Diskussion: Resultatdiskussionen diskuterades av författarna utifrån Katie Erikssons caritativa teori om att lindra lidande och utifrån centrala fynd utifrån temaområden i resultatet. / Background: Inflammatory bowel disease (IBD) is the collective name for chronic gastrointestinal disorders and includes Crohn's disease (CD) and Ulcerative colitis (UK). Both diseases relapses with recurring, long-term diarrhea with improvement and deterioration periods and can be related to physical, mental and social factors. In the absence of obvious causes or symptoms, it is in many ways a hidden disease and can create scarce understanding of the patient's specific needs. In order for the patient to receive the right support in the management of the disease and to receive good nursing care, the nurse have to give good care, have sufficient knowledge and care for the patient in a person-centered, evidence-based way. Aim: The purpose was to describe the patient’s experiences of living with inflammatory bowel disease, IBD. Method: A literature review was chosen as the method and was based on ten qualitative articles. Database searches were performed from CINAHL Complete and Medline with full text. The articles were analyzed according to Friberg's five steps. Results: In the result, six themes emerged from the patients' experience; the influence of IBD on the self-image, the influence of IBD in relationships and social contexts, patients' experience of health care, emotional impact, development and acceptance, and the influence of IBD in working life. Discussion: The results discussion was discussed by the authors on the basis of Katie Eriksson's charitable theory of alleviating suffering and on the basis of central findings based on thematic areas in the result.

The thesis deals with the topic of ulcerative colitis and its psychosocial impact upon adolescents. The main goal of the thesis is to identify, through qualitative research, the psychosocial factors that influence the adolescent in his everyday life and to map the situations that are most difficult for the teenager. The topic is based on the theoretical part, which consists of information about the diagnosis and course of ulcerative colitis, treatment methods and complications connected with them. The theoretical part also deals with describing the psychosocial factors of ulcerative colitis and describing adolescence as the stage of an individual's life. The research part describes a qualitative research method that answers the main research question. The output of a qualitative research survey is 7 identified areas that are most influenced by ulcerative colitis during adolescence. Key words: Ulcerative colitis, adolescence, psychosocial factors, chronical disease, impact, handicap, social impact

La maladie de Crohn (Crohn’s disease; CD) et la colite ulcéreuse (Ulcerative colitis ;CU) représentent deux formes distinctes de maladies inflammatoires chroniques de l’intestin (MICI), qui sont associées à une réponse immunitaire aberrante des tissus intestinaux à la flore intestinale. Les phagocytes mononucléés (MNPs) qui dialoguent, via les cytokines qu'ils produisent, avec les cellules immunitaires innées et adaptatives sont impliqués dans l’induction, la perpétuation et le maintien de la réponse inflammatoire des MICI. Chez la souris, les MNPs sont stratifiées en cellules dendritiques conventionnelles (cDCs), macrophages (M) et cellules dérivées de monocytes, une entité qui regroupe dans le tissu des cellules dendritiques dérivées de monocytes (Mo-DC), des M dérivés de monocytes et des « monocyte-like ». Toutefois, la diversité phénotypique, moléculaire et fonctionnelle des monocytes et des MNPs ainsi que la plasticité des monocytes restent à élucider dans les MICI. Les anticorps bloquant les cytokines IL12 et IL23 contrôlent la pathogénicité et la plasticité des cellules Th17, réduisant l'inflammation intestinale chez les patients atteints de MII. Cependant, il n’existe à ce jour aucun traitement curatif. L’étude approfondie de la plasticité des cellules T et du site tissulaire où elle pourrait se produire ne sont toujours pas clarifiés. Dans le premier chapitre, nous avons révélé l’existence de deux sous-populations distinctes de CD14+MNPs dans le colon de patients atteints de CU. Les cellules de type « inflammatory monocyte-like » CD14+CD163-CD64+ (P3) à l’opposé des CD14+CD163+CD64+ M (P4) s'accumulent dans le côlon inflammatoire. Nos résultats ont de plus établi un lien entre les P3 MNPs, l’IL12, l’IL1β et la détection de cellules Th17 mémoires produisant de l'IFN et de l'IL8, qui contribueraient collectivement à la pathogenèse de la CU. De plus, deux sous-populations CD14+ MNPs similaires sur le plan fonctionnel et moléculaire a ceux trouvés en CU, ont été détectées dans le côlon de patients atteints de CD. En revanche, dans le deuxième chapitre, nous fournissons des évidences que la sous-population monocytaire Slan+ pourrait contribuer à l’immunopathogenèse de la CD, mais pas à celle de la CU. La fréquence, le phénotype et la fonction des cellules Slan+ ont été examinés dans le sang, les ganglions mésentériques (MLN) et le côlon de patients atteints de MICI. Nous proposons que les cellules pro-inflammatoires CD14hiCD172α+Slan+ discriminent les tissus de CD et CU. En effet, elles ne s'accumulent que dans les MLNs et la muqueuse colique des patients atteints de CD. Dans le troisième chapitre, nous avons montré que les MLNs de CD et de CU, qui sont des tissus difficiles d'accès pour leur étude fonctionnelle en recherche, peuvent également être distingués par la distribution et le profil moléculaire des cellules T mémoire effectrices CXCR3-CCR6+ (Th17TEM). Nos données suggèrent également que la plasticité de Th17 se produit dans les MLNs avant leur migration vers l'intestin. Cette étude pourrait avoir des implications pour améliorer notre compréhension de la maladie. Enfin, il a été démontré qu’à l’homéostasie chez la souris, les monocytes sont continuellement recrutés dans la muqueuse intestinale où ils se différencient progressivement en M anti-inflammatoires. Ce processus de maturation est interrompu dans le contexte d'une inflammation. Les signaux environnementaux qui régulent la « cascade » de maturation d’un monocyte classique tissulaire demeurent inconnus chez l'homme. Dans le quatrième chapitre, nous avons récapitulé in vitro la cascade de différenciation des monocytes humains de «CD163- P3-like» en «CD163+P4-like» et avons montré leurs similitudes moléculaires avec les CD14+ MNP tissulaires. La manipulation de cette voie de différentiation pourrait ouvrir des pistes thérapeutiques pour restaurer l'homéostasie intestinale dans les MICI. En conclusion, une meilleure compréhension des sous-populations de MNPs, leurs fonction et plasticité dans la pathogenèse des MICI aidera à identifier des nouvelles cibles thérapeutiques et contribuera à augmenter les connaissances pour la mise au point de traitements personnalisés. / Crohn’s disease (CD) and ulcerative colitis (UC), the two forms of inflammatory bowel diseases (IBD), are associated with dysregulated immune response in the intestinal tissue. It is mediated by mononuclear phagocytes (MNPs) that dialogue via the cytokine they produce with innate and adaptive immune cells. In mice, MNPs are stratified into conventional dendritic cells (DCs), macrophages (M) and monocyte-derived cells that regroup tissue monocyte-derived DCs, monocyte-derived M and monocytes-like cells. However, the phenotypic, molecular and functional diversity of MNPs and their plasticity remain to be elucidated in IBD patients. Therapies in IBD employ antibodies that block IL12 and IL23, thus control Th17 pathogenicity and plasticity and decrease intestinal inflammation. However, no cure exist nowadays for the treatment of IBD. In-depth study of T cell plasticity and the tissue where it occurs remain to be investigated. In the first chapter, we revealed the existence of two distinct CD14+ MNP subsets in colon of UC patients. Only, CD163-CD64+ inflammatory monocyte-like cells (P3) but not anti-inflammatory CD163+CD64+ M (P4) accumulate in inflamed UC colon. Our findings further established a link between monocyte-like CD14hiCD172α+ CD163- MNPs, IL12, IL1β and the detection of colonic memory Th17 cells that produce IFN and IL8, which might all contribute to UC pathogenesis. Two CD14+ MNP subsets, resembling their counterparts in UC mucosa at the functional and molecular level, were also detected in CD colon. In contrast, in the second chapter, we provide evidence that Slan+ monocyte subset may contribute to CD but not UC immunopathogenesis. Frequency, phenotype, and function of Slan+ cells were examined in blood, colon, and mesenteric lymph nodes (MLN) of patients with IBD. We showed that pro-inflammatory CD14hiCD172α+Slan+ cells are a distinguishing feature between CD and UC, as they only accumulate in MLNs and colonic mucosa of CD patients. In the third chapter, we showed that MLNs of CD and UC, tissues that were hard to access for research use, can also be distinguished by frequencies of CXCR3−CCR6+ Th17 effector memory T cells (TEM) and their molecular profile. Our data further suggested that Th17 plasticity is taking place in MLN, before T cell homing to gut tissues. This investigation has clear implications in furthering our understanding of the disease. Finally, it has been demonstrated that monocytes are continuously recruited into murine gut mucosa and progressively differentiate into macrophages under homeostatic conditions, a maturation process interrupted in the context of inflammation. However, the environmental cues that regulate tissue inflammatory monocyte “waterfall” remain to be investigated in humans. In the fourth chapter we recapitulated in vitro human monocyte differentiation cascade, from CD163- inflammatory monocyte-like cells (P3) towards anti-inflammatory CD163+ macrophages (P4) and showed their molecular similarities to tissue CD14+ MNPs. Manipulating this pathway might open therapeutic avenues to restore tissue homeostasis. In conclusion, a better understanding of MNP subsets, function and plasticity in IBD pathogenesis would help identify novel therapeutic targets and shed light for the development of personalized treatments.

Bakgrund: Inflammatorisk mag-tarmsjukdom är ett samlingsnamn för Ulcerös kolit och Crohns sjukdom. Gemensamt för sjukdomarna är att de är kroniska och att de går i skov, vilket innebär att sjukdomen är mer aktiv i vissa perioder och mindre aktiv under andra. Inflammatorisk mag-tarmsjukdom påverkar patienterna fysiskt, psykiskt och socialt, vilket påverkar deras livskvalitet. Inflammatoriska mag-tarmsjukdomar kan resultera i psykiska besvär, därför har patienterna ett behov av goda copingstrategier och en god anpassning till livet med sjukdomen. Genom evidensbaserad och personcentrerad vård har sjuksköterskan en stödjande funktion i vården av dessa patienter.  Syfte: Syftet med litteraturstudien var att undersöka patienternas upplevelser av att leva med inflammatorisk mag-tarmsjukdom för att kunna belysa deras behov av stöd. Metod: En litteraturstudie med boolesk sökteknik gjordes i databaserna Cinahl, PubMed och PsycINFO där tio artiklar valdes ut genom granskning med SBU:s granskningsmall.    Resultat: När resultatet av tio artiklar sammanställts framkom fyra teman; patienters upplevelser av att leva med inflammatorisk mag-tarmsjukdom, patienternas behov av stöd, stöd i att acceptera och leva med sjukdomen samt stöd i form av utbildning. Slutsats: Patienter med inflammatorisk mag-tarmsjukdom har behov av stöd både fysiskt, psykiskt och socialt, från både sjukvårdspersonal och anhöriga. Patienterna har ett behov av stöd i form av information, undervisning samt psykiskt och emotionellt stöd. Sjuksköterskans stöd genom personcentrerad och empatisk kommunikation hjälper patienterna att acceptera sjukdomen och deras “nya normala”, vilket främjar deras självständighet, självkännedom och eget ansvar i sjukdomshanteringen. Patientutbildning bidrar till bättre egenvårdsstrategier, ökad följsamhet till behandling och livsstils anpassningar, vilket även bidrar till ökat självförtroende och välmående.

Background: Recent national trends and distribution of ileal pouch-anal anastomosis (IPAA) procedures for patients with ulcerative colitis (UC) are unknown. We examined the frequency of use of elective IPAA procedures among patients with UC and the distribution of IPAA procedures across more than 140 U.S. academic medical centers and their affiliates. Methods: Data were obtained from the University HealthSystem Consortium for patients with a primary diagnosis of UC admitted electively between 2012 and 2015. Results: The mean age of the study population (n=6,875) was 43 years and 57% were men. Among these, one-third (n=2,307) underwent an IPAA, while two-thirds (n=4,568) underwent colectomy, proctectomy, proctocolectomy or other procedures. The proportion of IPAA cases among all elective admissions was relatively stable at 33-35% during the years under study. A total of 131 hospitals, out of 279 hospitals participating in the UHC, performed IPAA. The median number of IPAA cases performed annually was 1.9 [IQR 0.8 – 4.3]. Nearly one half (48%) of these cases were performed by the top ten hospitals. Overall, only a total of 30 centers performed ³ five elective IPAA cases annually. Conclusions: Although the frequency of elective IPAA surgery in recent years has been stable, nearly one half of all IPAA cases was performed at ten hospitals. The concentration of IPAA cases at high-volume centers, and the steady number of cases performed annually, have potential implications for fellowship training, patient clinical outcomes and access to care.
