    BACKGROUND AND AIMS: Mucosal healing and histological remission are different targets for patients with ulcerative colitis, but both rely on an invasive endoscopic procedure. This study aimed to assess faecal calprotectin and neutrophil gelatinase B-associated lipocalin as biomarkers for disease activity in asymptomatic ulcerative colitis patients. METHODS: This was a multicentric cross-sectional study including 371 patients, who were classified according to their endoscopic and histological scores. These results were evaluated alongside the faecal levels of both biomarkers. RESULTS: Macroscopic lesions [i.e. endoscopic Mayo score ≥1] were present in 28% of the patients, and 9% had active disease according to fht Ulcerative Colitis Endoscopic Index of...

  3. Obstipação crónica – Novos agentes farmacológicos

    Martins, I; Figueiredo, L
    A obstipação crónica idiopática (OCI), uma doença frequente no âmbito da gastrenterologia, tem sofrido grandes desenvolvimentos nos últimos anos no que diz respeito à sua abordagem terapêutica. Actualmente, antes da instituição de uma terapêutica em “cascata”, preconiza-se a descontinuação, se possível, de fármacos potencialmente causadores de obstipação. Posteriormente está preconizado o início da utilização de laxantes e, quando necessário, até mesmo associá-los. Na tentativa de uma maior eficácia terapêutica, têm sido desenvolvidos novos fármacos, dos quais destacamos o prucalopride (procinético), a lubiprostona e a linaclotida (agentes secretores). O prucalopride foi aprovado no tratamento da OCI, mas ainda não se encontra disponível em Portugal. A lubiprostona foi aprovada no tratamento da OCI e do...

  4. Acute Hepatitis in the DRESS Syndrome

    Oliveira, AM; Carvalho, R; Martins, A; Reis, J
    Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe, idiosyncratic reaction characterized by diffuse maculopapular rash, facial edema, lym- phadenopathy, fever, eosinophilia and/or other leukocyte abnormalities, and involvement of internal organs as liver, kidney, heart and lung. Diagnosing this entity is specifically complicated due to the multiplicity of organs involved. DRESS syndrome must be recognized promptly and the causative drug withdrawn in order to improve patient outcomes. Indeed, it is a potentially life-threatening condition, with a reported mortality between 5 and 20%. We describe a case of a 22-year old woman admitted to our hospital with acute diffuse, pruritic rash associated with crampy abdominal pain, vomiting,...

  5. Isolated Visceral Angioedema Induced by Angiotensin-Converting Enzyme Inhibitor

    Oliveira, AM; Santiago, I; Carvalho, R; Martins, A; Reis, J
    Visceral angioedema is a rare complication of therapy with angiotensin-converting enzyme (ACE) inhibitors. Clinical presentation includes nausea, vomiting, abdominal pain and diarrhea. Early detection of this entity can prevent recurrent episodes and unnecessary invasive procedures, including surgery. This article describes a 46-year-old-woman who presented to the emergency department with abdominal pain, associated with nausea and vomiting. She had been taking ramipril for 15 days. A computed tomography was performed which revealed thickening of a jejunal segment, with submucosal edema. ACE inhibitor-associated angioedema was suspected and the medication was discontinued, with resolution of symptoms in 48 h. After 7 months of follow-up, the patient is asymptomatic. Despite of its rarity, ACE inhibitor-induced...

  11. Clinical and microbiological characteristics associated with mortality in spontaneous bacterial peritonitis: a multicenter cohort study.

    Oliveira, AM; Branco, JC; Barosa, R; Rodrigues, JA; Ramos, L; Martins, A; Karvellas, C; Cardoso, F
    OBJECTIVES: Spontaneous bacterial peritonitis (SBP) is a prevalent and high mortality complication of cirrhosis. We aimed to describe these patients' clinical and microbiological characteristics and evaluate their impact on outcomes. METHODS: This was a retrospective cohort study including 139 consecutive patients with positive culture SBP from three Portuguese centers diagnosed between 2009 and 2014. Multivariate logistic regression was used to study associations with 30-day mortality. RESULTS: The mean age of the patients was 62 years and 81% of patients were men. The mean model for end-stage liver disease score was 19. Hepatic encephalopathy, hepatorenal syndrome, and variceal bleeding developed in 47, 30, and 21% of...

  12. HBV-Associated Acute Liver Failure After Immunosuppression and Risk of Death.

    Karvellas, C; Cardoso, F; Gottfried, M; Reddy, R; Hanje, A; Ganger, D; Lee, W
    BACKGROUND & AIMS: Acute liver failure (ALF) caused by hepatitis B virus (HBV) infection can occur after immunosuppressive treatment and be fatal, although it might be preventable. We aimed to characterize the causes, clinical course, and short-term outcomes of HBV-associated ALF after immune-suppressive therapy, compared with patients with HBV-associated ALF without immunosuppression (control subjects). METHODS: We performed a retrospective multicenter study of 156 consecutive patients diagnosed with HBV-associated ALF (22 with a solid or blood malignancy) enrolled in the Acute Liver Failure Study Group registry from January 1998 through April 2015. We collected data on results of serologic and hepatic biochemistry analyses, grade...

  17. Abordagem terapêutica do polipo maligno

    Deus, JR
    A designação de polipo maligno significa a presença de um adenoma com um foco de carcinoma que invade a submucosa (carcinoma invasivo). Este tempo é habitualmente utilizado quando um polipo que foi ressecado por via endoscópica, se vem a comprovar, após exame histológico, conter carcinoma invasivo. A incidência de polipos malignos, removidos endoscopicamente, é em média de 4,7% (0,2-9,4%). O risco de malignidade está associado à dimensão, localização e configuração histológica. A abordagem terapêutica dum polipo maligno varia entre uma atitude conservadora, considerando a polipectomia tratamento adequado e suficiente e uma atitude cirúrgica de ressecção complementar, no caso contrário. A ressecção cirúrgica deverá tomar...

  19. Can red cell distribution width be used as a marker of Crohn's disease activity?

    Oliveira, AM; Cardoso, F; Rodrigues, C; Santos, L; Martins, A; Deus, JR; Reis, J
    Introduction: Recently, it has been suggested an association between red cell distribution width (RDW) and Crohn’s disease activity index (CDAI), but its use is not yet performed in daily clinical practice. Objectives: To determine whether RDW can be used as a marker of Crohn’s disease (CD) activity. Methods: This was a cross-sectional study including patients with CD, observed consecutively in an outpatient setting between January 1st and September 30th 2013. Blood cell indices, erythrocyte sedimentation rate (ESR), and C-reactive protein were measured. CD activity was determined by CDAI (active disease if CDAI ≥ 150). Associations were analyzed using logistic regression (SPSS version 20). Results: 119 patients (56% female) were...

  20. C-reactive protein at 24 hours after hospital admission may have relevant prognostic accuracy in acute pancreatitis: a retrospective cohort study

    Cardoso, F; Ricardo, L; Oliveira, AM; Horta, D; Papoila, A; Deus, JR; Canena, J
    Introduction: C-reactive protein (CRP) and Bedside Index for Severity in Acute Pancreatitis (BISAP) have been used in early risk assessment of patients with AP. Objectives: We evaluated prognostic accuracy of CRP at 24 hours after hospital admission (CRP24) for in-hospital mortality (IM) in AP individually and with BISAP. Materials and Methods: This retrospective cohort study included 134 patients with AP from a Portuguese hospital in 2009---2010. Prognostic accuracy assessment used area under receiver---operating characteristic curve (AUC), continuous net reclassification improvement (NRI), and integrated discrimination improvement (IDI).
