RESUMO
BACKGROUND: Anti-TNFα represent one of the main treatment approaches for the management of inflammatory bowel diseases (IBD). Therefore,the evaluation of their treatment patterns over time provides valuable insights about the clinical value of therapies and associated costs. AIMS: To assess the treatment patterns with the first anti-TNFα in IBD. METHODS: Retrospective, observational study. RESULTS: 310 IBD patients were analyzed along a 5-year follow-up period. 56.2% of Crohn's disease (CD) patients started with adalimumab (ADA), while 43.8% started with infliximab (IFX). 12.9% of ulcerative colitis (UC) patients initiated with ADA, while 87.1% initiated with IFX. Treatment intensification was required in 28.9% of CD and 37.1% of UC patients. Median time to treatment intensification was shorter in UC than in CD (5.3 vs. 14.3 months; p = 0.028). Treatment discontinuation due to reasons other than remission were observed in 40.7% of CD and 40.5% of UC patients, although, in UC patients there was a trend to lower discontinuation rates with IFX (36.6%) than with ADA (66.7%). Loss of response accounted for approximately one-third of discontinuations, in both CD and UC. CONCLUSIONS: Around one-third of IBD biologic-naive patients treated with an anti-TNFα required treatment intensification (earlier in UC) and around 40% discontinued the anti-TNFα due to inappropriate disease control.

OBJECTIVES: To determine the efficacy and safety of cyclosporine (CyA) in a large national registry-based population of patients with steroid-refractory (SR) acute severe ulcerative colitis (ASUC) and to establish predictors of efficacy and adverse events. METHODS: Multicenter study of SR-ASUC treated with CyA, based on data from the ENEIDA registry. SR-ASUC patients treated with infliximab (IFX) or sequential rescue therapy (CyA-IFX or IFX-CyA) were used as comparators. RESULTS: Of 740 SR-ASUC patients, 377 received CyA, 131 IFX and 63 sequential rescue therapy. The cumulative colectomy rate was higher in the CyA (24.1%) and sequential therapy (32.7%) than in the IFX group (14.5%; P=0.01) at 3 months and 5 years. There were no differences in early and late colectomy between CyA and IFX in patients treated after 2005. 62% of patients receiving CyA remained colectomy-free in the long term (median 71 months). There were no differences in mortality between CyA (2.4%), IFX (1.5%) and sequential therapy (0%; P=0.771). The proportion of patients with serious adverse events (SAEs) was lower in CyA (15.4%) than in IFX treated patients (26.5%) or sequential therapy (33.4%; P<0.001). This difference in favor of CyA was maintained when only patients treated after 2005 were analyzed. CONCLUSIONS: Treatment with CyA showed a lower rate of SAE and a similar efficacy to that of IFX thereby supporting the use of either CyA or IFX in SR-ASUC. In addition, the risk-benefit of sequential CyA-IFX for CyA non-responders is acceptable.

Inflammatory bowel disease (IBD) is a complex entity that includes Crohn disease and ulcerative colitis. It is characterized by a chronic proinflammatory state of varying intensity that often leads to considerable morbidity. In the last decade, several therapeutic targets have been identified that are susceptible to the use of biological agents, including anti-tumor necrosis factor alpha antibodies, which are associated with paradoxical psoriasiform reactions in 5% of patients. Decision-making in the management of these cases requires close collaboration between the dermatologist and gastroenterologist. Inflammatory bowel disease is also associated with various other dermatologic and rheumatologic manifestations, and presents a genetic and pathogenic association with psoriasis that justifies both the interdisciplinary approach to these patients and the present review.

Chronic diarrhoea is a common presenting symptom in both primary care medicine and in specialized gastroenterology clinics. It is estimated that >5% of the population has chronic diarrhoea and nearly 40% of these patients are older than 60 years. Clinicians often need to select the best diagnostic approach to these patients and choose between the multiple diagnostic tests available. In 2014 the Catalan Society of Gastroenterology formed a working group with the main objective of creating diagnostic algorithms based on clinical practice and to evaluate diagnostic tests and the scientific evidence available for their use. The GRADE system was used to classify scientific evidence and strength of recommendations. The consensus document contains 28 recommendations and 6 diagnostic algorithms. The document also describes criteria for referral from primary to specialized care.
La diarrea crónica es un síntoma de presentación frecuente, tanto en las consultas de medicina de familia como en las de digestivo. Se estima que >5% de la población sufre diarrea crónica y que cerca del 40% de estos sujetos son mayores de 60 años. El clínico se enfrenta con frecuencia a la necesidad de decidir cuál es el mejor enfoque diagnóstico de estos pacientes y elegir entre las múltiples pruebas diagnósticas existentes. En 2014 la Societat Catalana de Digestologia creó un grupo de trabajo con el objetivo principal de crear algoritmos diagnósticos en base a la práctica clínica y evaluar las pruebas diagnósticas disponibles y la evidencia científica para su utilización. Para clasificar la evidencia científica y la fuerza de las recomendaciones se utilizó el sistema GRADE. Se han establecido 28 recomendaciones y 6 algoritmos diagnósticos. Se describen los criterios de derivación desde medicina primaria a digestivo de un paciente con diarrea crónica.

BACKGROUND: Microscopic colitis (MC) is an underdiagnosed inflammatory bowel disease. AIM: To develop an evidence-based clinical practice guide on MC current concepts. METHODS: Literature search was done on the Cochrane Library, EMBASE and MEDLINE electronic databases, which were consulted covering the period up until March 2015. Work groups were selected for each of the reviewed topics, with the purpose of drafting the initial statements and recommendations. They subsequently underwent a voting process based on the Delphi method. Each statement/recommendation was accompanied by the result of the vote the level of evidence, and discussion of the corresponding evidence. The grade of recommendation (GR) using the GRADE approach was established for diagnosis and treatment recommendations. RESULTS: Some key statements and recommendations are: advancing age increases the risk of developing MC, mainly in females. The symptoms of MC and IBS-D may be similar. If MC is suspected, colonoscopy taking biopsies is mandatory. Treatment with oral budesonide is recommended to induce clinical remission in patients with MC. Oral mesalazine is not recommended in patients with collagenous colitis for the induction of clinical remission. The use of anti-TNF-alpha drugs (infliximab, adalimumab) is recommended for the induction of remission in severe cases of MC that fail to respond to corticosteroids or immunomodulators, as an alternative to colectomy. CONCLUSIONS: This is the first consensus paper on MC based on GRADE methodology. This initiative may help physicians involved in care of these patients in taking decisions based on evidence.

BACKGROUND: Phenotypic traits of familial IBD relative to sporadic cases are controversial, probably related to limited statistical power of published evidence. AIM: To know if there are phenotype differences between familial and sporadic IBD, evaluating the prospective Spanish registry (ENEIDA) with 11,983 cases. METHODS: 5783 patients (48.3%) had ulcerative colitis (UC) and 6200 (51.7%) Crohn's disease (CD). Cases with one or more 1st, 2nd or 3rd degree relatives affected by UC/CD were defined as familial case. RESULTS: In UC and CD, familial cases compared with sporadic cases had an earlier disease onset (UC: 33 years [IQR 25-44] vs 37 years [IQR 27-49]; p<0.0001); (CD: 27 years [IQR 21-35] vs 29 years [IQR 22-40]; p<0.0001), higher prevalence of extraintestinal immune-related manifestations (EIMs) (UC: 17.2% vs 14%; p=0.04); (CD: 30.1% vs 23.6%; p<0.0001). Familial CD had higher percentage of ileocolic location (42.7% vs 51.8%; p=0.0001), penetrating behavior (21% vs 17.6%; p=0.01) and perianal disease (32% vs 27.1%; p=0.003). Differences are not influenced by degree of consanguinity. CONCLUSION: When a sufficiently powered cohort is evaluated, familial aggregation in IBD is associated to an earlier disease onset, more EIMs and more severe phenotype in CD. This feature should be taken into account at establishing predictors of disease course.

BACKGROUND: Recently, the notion that smoking may adversely affect Crohn's disease (CD) outcomes has been challenged by the suggestion that the widespread use of immunosuppressants and anti-TNF drugs might offset the adverse effects of tobacco. AIM: To reassess the influence of tobacco smoking on disease phenotype and complications on a time-dependent analysis, taking into account the different therapeutic interventions. METHODS: We designed a retrospective cohort study of 3224 patients with Crohn's disease. The data were collected from the Spanish national inflammatory bowel disease registry (ENEIDA), including information regarding demographics, clinical characteristics, disease complications, therapeutic interventions and smoking status. Patients were classified as nonsmokers, smokers and former smokers, according to their present and past smoking habits. RESULTS: In the univariate analysis, smokers had more strictures (22.6% vs. 19.3%, P < 0.05) and less colonic involvement (7.2% vs. 10.9%, P < 0.05), and were more frequently under treatment with steroids (91.6% vs. 85.8%, P < 0.05), immunosuppressants (73.5% vs. 63.6% P < 0.05) or anti-TNF drugs (31.4% vs. 25.1%, P < 0.05) than nonsmokers. In the time-dependent multivariate analysis, smokers were found to have a significantly decreased survival free of stricturing disease (HR: 1.5, CI 95% 1.18-1.90) or perianal complications (HR: 1.50, CI 95% 1.01-1.46), and had a higher risk for requiring thiopurine therapy (HR: 1.20, CI 95% 1.05-1.30). CONCLUSION: These results suggest that, despite the widespread use of immunosuppressants and anti-TNF drugs, smokers with Crohn's disease still have a more severe disease course, with increased therapeutic requirements when compared with nonsmokers.

OBJECTIVES: The safety of thiopurines and anti-tumor necrosis factor-α (TNF-α) drugs during pregnancy remains controversial, as the experience with these drugs in this situation is limited. Our aim is to assess the safety of thiopurines and anti-TNF-α drugs for the treatment of inflammatory bowel disease (IBD) during pregnancy. METHODS: Retrospective, multicenter study in IBD patients. Pregnancies were classified according to the therapeutic regimens during pregnancy or during the 3 months before the conception: non-exposed group, pregnancies exposed to thiopurines alone (group A), and pregnancies exposed to anti-TNF-α drugs (group B). An unfavorable Global Pregnancy Outcome (GPO) was considered if pregnancy developed with obstetric complications in the mother and in the newborn. RESULTS: A total of 187 pregnancies in the group A, 66 pregnancies in the group B, and 318 pregnancies in the non-exposed group were included. The rate of unfavorable GPO was different among the three groups (31.8% in non-exposed group, 21.9% in group A, and 34.8% in group B), being lower in pregnancies under thiopurines than among non-exposed (P = 0.01). The rate of pregnancy complications was similar among the three groups (27.7% in non-exposed, 20.9% in group A, and 30.3% in group B). The rate of neonatal complications was different among the three groups (23.3% in non-exposed group, 13.9% in group A, and 21.2% in group B), being lower in pregnancies under thiopurines than among non-exposed (P = 0.01). In the multivariate analysis, the treatment with thiopurines (odds ratio = 0.6; 95% confidence interval = 0.4-0.9, P = 0.02) was the only predictor of favorable GPO, whereas maternal age >35 years at conception was the only predictor of unfavorable GPO. The treatment with anti-TNF-α drugs was not associated with an unfavorable GPO. CONCLUSION: The treatment with thiopurines and anti-TNF-α drugs does not seem to increase the risk of complications during pregnancy and does seem to be safe for the newborn.

BACKGROUND: Adalimumab is an effective treatment for Crohn's disease (CD), but may also be associated with loss of response. Few reports provide insight into the durability of treatment of CD with adalimumab for periods longer than 12 months in clinical practice. AIMS: To evaluate the long-term durability of adalimumab maintenance treatment and to identify predictive factors associated with loss of response. METHODS: CD patients who initially responded to adalimumab were evaluated in a historical cohort study. Maintenance of long-term response was estimated using Kaplan-Meier analysis. Cox regression analysis was performed to identify potential predictive factors for loss of efficacy. RESULTS: In all, 380 CD patients were included (mean age, 38 years; 52% female). Of these, 43% had ileocolic CD, 50% inflammatory CD, and 41% perianal CD. Median follow-up with adalimumab was 8 months (range, 4-75 months). The annual risk of loss of response to adalimumab was 18% per patient-year of follow-up. Twenty-eight percent of patients were anti-TNF-naïve and 72% anti-TNF-experienced. The loss of efficacy was 8% per patient-year of follow-up in the anti-TNF-naïve patients and 22% in the anti-TNF-experienced group (P < 0.01). In the multivariate analysis, the presence of extraintestinal manifestations (hazard ratio [HR] = 1.7; 95% confidence interval [CI] = 1.02-2.9) and previous experience with other anti-TNF agents (HR = 2.5,95% CI = 1.2-5.3) were associated with higher risk of loss of efficacy. CONCLUSIONS: A relevant proportion of CD patients on long-term adalimumab lost response. The risk of loss of response was higher (more than 2-fold) in anti-TNF-experienced than in anti-TNF-naïve patients (22% vs. 8% per patient-year of treatment). Having extraintestinal manifestations seems to increase the risk of loss of efficacy.

BACKGROUND: Ciclosporin has proven to be effective in patients with corticosteroid-refractory ulcerative colitis (UC). When therapy with this drug fails, infliximab can be considered to avoid colectomy. The efficacy and safety of this sequential approach remain unknown. AIM: To assess the efficacy and safety profile of treatment with infliximab after failure of ciclosporin in patients with a corticosteroid-refractory flare of UC. METHODS: Retrospective review of medical records of patients with a corticosteroid-refractory flare of UC who did not respond to ciclosporin and received salvage therapy with infliximab within a month of discontinuing ciclosporin. The severity of the flare and response to the treatment were graded using the Lichtiger index. Cumulative rates of colectomy were calculated using Kaplan-Meier analysis. Cox regression analysis was performed to identify predictors of colectomy. To evaluate the safety profile of this treatment strategy, any adverse event occurring after the first infusion of infliximab was considered. RESULTS: The study population comprised 47 patients with corticosteroid-refractory UC treated with infliximab after failure of ciclosporin. The median baseline Lichtiger index was 13. The mean time from the last ciclosporin dose to the first infliximab infusion was 6 days. After the first infliximab infusion, 13% of patients achieved remission, and 74% partial response. Of the 35 patients who received the third infliximab infusion, 60% achieved remission, and 37% partial response. Fourteen patients (30%) underwent colectomy. The rate of adverse events was 23%. One death occurred in a 40-year-old man who failed ciclosporin and infliximab and underwent surgery 10 days after the first infliximab infusion; he died of nosocomial pneumonia. CONCLUSIONS: Treatment with infliximab makes it possible to avoid colectomy in two-thirds of corticosteroid-refractory UC patients in whom ciclosporin fails. However, the rates of adverse events and mortality mean that the decision to administer sequential therapy (ciclosporin-infliximab) should be taken on an individual basis.

BACKGROUND: Most available data on infliximab therapy come from large, short-term, pivotal RCTs and concerns about long-term safety profile still remain. AIM: To evaluate the long-term safety profile of infliximab in inflammatory bowel disease (IBD) in a clinical practice setting. METHODS: Since 1999, all IBD patients treated with infliximab were registered and clinical outcomes prospectively recorded up to March 2008, loss of follow-up or patient's death. Infliximab regimens and preventive measures were in accordance with the prevalent guidelines or with the manufacturer's recommendations. RESULTS: One hundred fifty-two patients were included (121 Crohn's disease, 24 ulcerative colitis, 7 indeterminate colitis), with a median of 5 infliximab infusions (IQR 3-8) and 87% of patients received at least three infusions. Seventy-nine per cent of them received concomitant immunomodulators and 70% were pre-medicated with hydrocortisone from the first infusion. After a median follow-up of 142 weeks, 13% presented infusion reactions, 13% viral or bacterial infections and two patients developed neoplasia. The mortality rate was 2.6% (four patients). CONCLUSIONS: Infliximab therapy is safe when the recommended preventive measures are implemented, with a rate of serious adverse events less than 10%. No new safety signals were found.

BACKGROUND: Infliximab (IFX) could change the course of Crohn's disease (CD) by reducing steroid use, surgery or prompting earlier introduction of immunomodulators (IMM). AIM: To evaluate the impact of IFX availability on the course of early CD. METHODS: Two cohorts of newly diagnosed CD patients were identified: The first cohort included patients diagnosed from January 1994 to December 1997 and the second from January 2000 to December 2003. All patients were diagnosed, treated and followed up in the same centre until December 1999 (first cohort) or December 2005 (second cohort). Development of disease-related complications, steroid, IMM or IFX requirements and intestinal resections during follow-up were registered. RESULTS: A total of 328 patients were included (146 first cohort, 182 second cohort). A similar proportion of patients in both cohorts received steroids, but steroid exposure resulted significantly more intense in the first cohort (P = 0.001). In the second cohort, 14% of patients received IFX. Thiopurines were used more (P = 0.001) and earlier (P = 0.012) in the second cohort. No differences in surgical requirements or the development of disease-related complications were found. CONCLUSIONS: Following a step-up therapeutic algorithm, IFX availability did not reduce surgical requirements or the development of disease-related complications.

BACKGROUND: Few data are available regarding the evolution of Crohn's disease after discontinuing a successful course of infliximab. AIM: To evaluate clinical outcome of Crohn's disease after induction of remission with three infliximab infusions (luminal disease) and after maintenance of remission with 1-year course of infliximab every 8 weeks (luminal and perianal). METHODS: Twenty-three patients with active luminal Crohn's disease who responded to three infusions of infliximab (0, 2, and 6 weeks), and 23 patients with sustained response to infliximab every 8 weeks during 1 year, were included. Patients were followed-up until relapse or for at least 6 months after infliximab discontinuation. Clinical outcomes and factors associated to relapse were evaluated. RESULTS: In luminal Crohn's disease, a three-infusion infliximab regimen achieved a sustained response in most patients, especially if a complete response occurred at the time of the third infusion. In patients treated for 1-year, infliximab discontinuation was also successful, with a cumulative probability of being free of relapse of 69% at 12 months. In perianal disease, early relapse was the rule after stopping infliximab treatment, with only 34% of patient maintaining remission at 1 year. CONCLUSIONS: Short regimens of infliximab might be evaluated in patients with luminal Crohn's disease. However, infliximab discontinuation is not recommended in perianal Crohn's disease, because of a high rate of early relapse.

The incidence of immunological disorders has been reported to be greater in patients with inflammatory bowel disease than among the general population. The association of ulcerative colitis (UC) and autoimmune hemolytic anemia (AIHA) was first described in the early 1950s but no more than 50 cases have been described in the international literature. Detailed description of the pathogenic mechanisms involved in this association is lacking. The clinical course of AIHA and treatment response in these patients seems to be independent of UC, sometimes requiring immunosuppressive treatment and even surgery. We present 2 cases of AIHA associated with UC with distinct response to conventional treatment. We also review the literature on the subject.

OBJECTIVES: Surgical resection is still a mainstay of the treatment of Crohn's disease (CD). However, recurrence is the rule. The aim of the present study was to evaluate CD recurrence in a series of patients who underwent surgical resection with subsequent treatment with azathioprine (AZA) or mesalazine (5-ASA) and to identify the factors associated with recurrence. METHODS: The medical records of patients with CD who underwent bowel resection during a 4-year period were reviewed. Only patients who received AZA or 5-ASA as prophylaxis for recurrence were included. RESULTS: Thirty-three patients treated with AZA and 16 treated with 5-ASA were included. Endoscopic recurrence was found in 8.6% of the AZA group and in 87.5% of the 5-ASA group (p <0.001). Clinical recurrence occurred in 31.2% of patients in the 5-ASA group and in none in the AZA group (p=0.004). The accumulated probability of both clinical and endoscopic recurrence was significantly lower in the AZA group (p=0.0025 and p=0.005, respectively). Factors associated with a greater risk of endoscopic recurrence were termino-terminal anastomosis and 5-ASA treatment. The only factor associated with clinical recurrence was 5-ASA treatment. CONCLUSION: AZA seems to be more effective than 5-ASA in the prevention of postsurgical endoscopic recurrence of CD. Prospective studies with long-term follow-up are required to establish the true utility of AZA in the prophylaxis of CD recurrence.

Immunosuppressive agents (azathioprine, methotrexate) are increasingly being used in the treatment of inflammatory bowel disease. The use of immunosuppressive agents is associated with a greater risk of opportunistic infections, the most frequent of which are those caused by cytomegalovirus and varicella zoster virus. We present four cases of opportunistic infections due to Herpesviruses in patients undergoing immunosuppressive treatment with azathioprine for Crohn's disease. We also review the literature published on this topic. Two patients presented cutaneous varicella complicated by pneumonia and esophagitis respectively, one patient had cutaneous herpes zoster and the other had fatal pneumonia possibly caused by the Herpesvirus. In the first three the clinical course of the infection was favorable after withdrawing immunosuppressant treatment and initiating treatment with aziclovir. In patients Crohn's disease azathioprine treatment increases the risk of opportunistic infection by Herpesvirus. However, in the absence of other factors that increase immunosuppression, these infections usually have a benign course with specific antiviral therapy.

BACKGROUND: Intravenous ciclosporin is considered to be the only alternative to avoid surgery in severe, steroid-refractory ulcerative colitis. In responders, some authors recommend a switch to oral ciclosporin to act as a 'bridge' until the therapeutic action of azathioprine is achieved for maintenance treatment. AIM: To report the short- and long-term outcome of intravenous ciclosporin-responsive ulcerative colitis patients treated with oral azathioprine without oral ciclosporin. METHODS: The records of all patients treated with intravenous ciclosporin for severe, steroid-refractory ulcerative colitis were reviewed. Responders following treatment with azathioprine but without oral ciclosporin as maintenance therapy were included. Patients with colonic cytomegalovirus infection and/or follow-up of less than 1 year were excluded. RESULTS: Twenty-seven patients were included. Steroids were discontinued in 24 (89%). The median follow-up was 36 months. Eighteen (75%) patients presented mild or moderate relapses, which were easily managed with salicylates or steroids. Cumulative probabilities of relapse were 42%, 72% and 77% at 1, 3 and 5 years, respectively. Eleven (40.7%) patients underwent elective colectomy. Cumulative probabilities of colectomy were 29%, 35% and 42% at 1, 3 and 5 years, respectively. No opportunistic infections were observed. CONCLUSIONS: Oral azathioprine seems to be enough to maintain long-term remission induced by intravenous ciclosporin in patients with steroid-refractory ulcerative colitis. The 'bridging step' with oral ciclosporin may not be necessary in this subset of patients, although a randomized controlled trial is warranted to confirm this hypothesis.
