Therapeutic optimization through goal-oriented prescription in nursing homes.

Background People living in nursing homes are highly vulnerable and frail. Polypharmacy and inappropriate prescription (IP) are also common problems. Objectives The objectives of the study are (i) to study the baseline situation and calculate the frailty index (FI) of the residents, (ii) to assess the results of routine clinical practice to do a pharmacotherapy review (patient-centred prescription (PCP) model) (Molist Brunet et al., Eur Geriatr Med. 2015;6:565-9) and (iii) to study the relationship between IP and frailty, functional dependence, advanced dementia and end-of-life situation. Setting Two nursing homes in the same geographical area in Catalonia (Spain). Method This was a prospective, descriptive and observational study of elderly nursing home residents. Each patient's treatment was analysed by applying the PCP model, which centres therapeutic decisions on the patient's global assessment and individual therapeutic goal. Main outcome measure Prevalence of polypharmacy and IP. Results 103 patients were included. They were characterized by high multimorbidity and frailty. Up to 59.2% were totally dependent. At least one IP was identified in 92.2% of residents. Prior to the pharmacological review, the mean number of chronic medications prescribed per resident was 6.63 (SD 2.93) and after this review it was 4.97 (SD 2.88). Polypharmacy decreased from 72.55% to 52.94% and excessive polypharmacy fell from 18.62% to 5.88%.The highest prevalence of IP was detected in people with a higher FI, in those identified as end-of-life, and also in more highly dependent residents (p < 0.05). Conclusions People who live in nursing homes have an advanced frailty. Establishing individualized therapeutic objectives with the application of the PCP model enabled to detect 92.2% of IP. People who are frailer, are functionally more dependent and those who are end-of-life are prescribed with inappropriate medication more frequently.

Prevalence and Factors Associated With Fatigue in Patients With Inflammatory Bowel Disease: A Multicentre Study.

BACKGROUND AND AIMS: The aims of this study were to determine the prevalence of fatigue in patients with inflammatory bowel disease [IBD], to identify the factors associated with fatigue and its severity, to assess the impact of fatigue on quality of life [QoL], and to evaluate the relationship between fatigue and sleep disorders. METHODS: This was a prospective multicentre study conducted at 22 Spanish centres. Consecutive patients followed at IBD Units were included. Fatigue was evaluated with the Fatigue Severity Scale [FSS] and the Fatigue Impact Scale [FIS]. Quality of life and sleep quality were assessed using the IBD Questionnaire-Short Form [IBDQ-9] and the Pittsburgh Sleep Quality Index [PSQI], respectively. RESULTS: A total of 544 consecutive adult IBD patients were included [50% women, mean age 44 years, 61% Crohn's disease]. The prevalence of fatigue was 41% (95% confidence interval [CI] = 37-45%). The variables associated with an increased risk of fatigue were: anxiety [OR = 2.5, 95% CI = 1.6-3.7], depression [OR = 2.4, 95% CI = 1.4-3.8], presence of extraintestinal manifestations [EIMs] [OR = 1.7, 95% CI = 1.1-2.6], and treatment with systemic steroids [OR = 2.8, 95% CI = 1.4-5.7]. The presence of EIMs [regression coefficient, RC = 8.2, 95% CI = 2.3-14.2], anxiety [RC = 25.8, 95% CI = 20.0-31.5], depression [RC = 30.6, 95% CI = 24.3-37.0], and sleep disturbances [RC = 15.0, 95% CI = 9.3-20.8] were associated with severity of fatigue. Patients with fatigue had a significantly decreased IBDQ-9 score [p < 0.001]. CONCLUSIONS: The prevalence of fatigue in IBD patients is remarkably high and has a negative impact on QoL. Therapy with systemic steroids is associated with an increased risk of fatigue. The severity of fatigue is associated with anxiety, depression, sleep disorders, and the presence of EIMs. Fatigue was not associated with anaemia, disease activity or anti-TNF therapy.

Post-operative morbidity and mortality of a cohort of steroid refractory acute severe ulcerative colitis: Nationwide multicenter study of the GETECCU ENEIDA Registry.

BACKGROUND: Despite the increased use of rescue medical therapies for steroid refractory acute severe ulcerative colitis, mortality related to this entity still remains high. We aimed to assess the mortality and morbidity related to colectomy and their predictive factors in steroid refractory acute severe ulcerative colitis, and to evaluate the changes in mortality rates, complications, indications of colectomy, and the use of rescue therapy over time. METHODS: We performed a multicenter observational study of patients with steroid refractory acute severe ulcerative colitis requiring colectomy, admitted to 23 Spanish hospitals included in the ENEIDA registry (GETECCU) from 1989 to 2014. Independent predictive factors of mortality were assessed by binary logistic regression analysis. Mortality along the study was calculated using the age-standardized rate. RESULTS: During the study period, 429 patients underwent colectomy, presenting an overall mortality rate of 6.3% (range, 0-30%). The main causes of death were infections and post-operative complications. Independent predictive factors of mortality were: age ≥50 years (OR 23.34; 95% CI: 6.46-84.311; p < 0.0001), undergoing surgery in a secondary care hospital (OR 3.07; 95% CI: 1.01-9.35; p = 0.047), and in an emergency setting (OR 10.47; 95% CI: 1.26-86.55; p = 0.029). Neither the use of rescue medical treatment nor the type of surgical technique used (laparoscopy vs. open laparotomy) influenced mortality. The proportion of patients undergoing surgery in an emergency setting decreased over time (p < 0.0001), whereas the use of rescue medical therapy prior to colectomy progressively increased (p > 0.001). CONCLUSIONS: The mortality rate related to colectomy in steroid refractory acute severe ulcerative colitis varies greatly among hospitals, reinforcing the need for a continuous audit to achieve quality standards. The increasing use of rescue therapy is not associated with a worse outcome and may contribute to reducing emergency surgical interventions and improve outcomes.

Long-Term Efficacy and Safety of Cyclosporine in a Cohort of Steroid-Refractory Acute Severe Ulcerative Colitis Patients from the ENEIDA Registry (1989-2013): A Nationwide Multicenter Study.

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.

Extracolonic Cancer in Inflammatory Bowel Disease: Data from the GETECCU Eneida Registry.

OBJECTIVES: The objective of this study was (a) To know the prevalence and distribution of extracolonic cancer (EC) in patients with inflammatory bowel disease (IBD); (b) To estimate the incidence rate of EC; (c) To evaluate the association between EC and treatment with immunosuppressants and anti-tumor necrosis factor (TNF) agents. METHODS: This was an observational cohort study. INCLUSION CRITERIA: IBD and inclusion in the ENEIDA Project (a prospectively maintained registry) from GETECCU. EXCLUSION CRITERIA: Patients with EC before the diagnosis of IBD, lack of relevant data for this study, and previous treatment with immunosuppressants other than corticosteroids, thiopurines, methotrexate, or anti-TNF agents. The Kaplan-Meier method was used to evaluate the impact of several variables on the risk of EC, and any differences between survival curves were evaluated using the log-rank test. Stepwise multivariate Cox regression analysis was used to investigate factors potentially associated with the development of EC, including drugs for the treatment of IBD, during follow-up. RESULTS: A total of 11,011 patients met the inclusion criteria and were followed for a median of 98 months. Forty-eight percent of patients (5,303) had been exposed to immunosuppressants or anti-TNF drugs, 45.8% had been exposed to thiopurines, 4.7% to methotrexate, and 21.6% to anti-TNF drugs. The prevalence of EC was 3.6%. In the multivariate analysis, age (HR=1.05, 95% CI=1.04-1.06) and having smoked (hazards ratio (HR)=1.47, 95% confidence interval (CI)=1.10-1.80) were the only variables associated with a higher risk of EC. CONCLUSIONS: Neither immunosuppressants nor anti-TNF drugs seem to increase the risk of EC. Older age and smoking were associated with a higher prevalence of EC.

[Consensus document on pneumococcal vaccination in adults at risk by age and underlying clinical conditions. 2017 Update]. / Consenso sobre la vacunación anti-neumocócica en el adulto por riesgo de edad y patología de base. Actualización 2017.

Invasive pneumococcal disease (IPD) and pneumococcal pneumonia (PP) represent an important health problem among aging adults and those with certain underlying pathologies and some diseases, especially immunosuppressed and some immunocompetent subjects, who are more susceptible to infections and present greater severity and worse evolution. Among the strategies to prevent IPD and PP, vaccination has its place, although vaccination coverage in this group is lower than desirable. Nowadays, there are 2 vaccines available for adults. Polysacharide vaccine (PPV23), used in patients aged 2 and older since decades ago, includes a greater number of serotypes (23), but it does not generate immune memory, antibody levels decrease with time, causes an immune tolerance phenomenon, and have no effect on nasopharyngeal colonization. PCV13 can be used from children 6 weeks of age to elderly and generates an immune response more powerful than PPV23 against most of the 13 serotypes included in it. In the year 2013 the 16 most directly related to groups of risk of presenting IPD publised a series of vaccine recommendations based on scientific evidence regarding anti-pneumococcal vaccination in adults with underlying pathologies and special conditions. A commitment was made about updating it if new scientific evidence became available. We present an exhaustive revised document focusing mainly in recommendation by age in which some more Scientific Societies have been involved.

Evolution After Anti-TNF Discontinuation in Patients With Inflammatory Bowel Disease: A Multicenter Long-Term Follow-Up Study.

OBJECTIVES: The aims of this study were to assess the risk of relapse after discontinuation of anti-tumor necrosis factor (anti-TNF) drugs in patients with inflammatory bowel disease (IBD), to identify the factors associated with relapse, and to evaluate the overcome after retreatment with the same anti-TNF in those who relapsed. METHODS: This was a retrospective, observational, multicenter study. IBD patients who had been treated with anti-TNFs and in whom these drugs were discontinued after clinical remission was achieved were included. RESULTS: A total of 1,055 patients were included. The incidence rate of relapse was 19% and 17% per patient-year in Crohn's disease and ulcerative colitis patients, respectively. In both Crohn's disease and ulcerative colitis patients in deep remission, the incidence rate of relapse was 19% per patient-year. The treatment with adalimumab vs. infliximab (hazard ratio (HR)=1.29; 95% confidence interval (CI)=1.01-1.66), elective discontinuation of anti-TNFs (HR=1.90; 95% CI=1.07-3.37) or discontinuation because of adverse events (HR=2.33; 95% CI=1.27-2.02) vs. a top-down strategy, colonic localization (HR=1.51; 95% CI=1.13-2.02) vs. ileal, and stricturing behavior (HR=1.5; 95% CI=1.09-2.05) vs. inflammatory were associated with a higher risk of relapse in Crohn's disease patients, whereas treatment with immunomodulators after discontinuation (HR=0.67; 95% CI=0.51-0.87) and age (HR=0.98; 95% CI=0.97-0.99) were protective factors. None of the factors were predictive in ulcerative colitis patients. Retreatment of relapse with the same anti-TNF was effective (80% responded) and safe. CONCLUSIONS: The incidence rate of inflammatory bowel disease relapse after anti-TNF discontinuation is relevant. Some predictive factors of relapse after anti-TNF withdrawal have been identified. Retreatment with the same anti-TNF drug was effective and safe.

Standardization of the homogeneous mobility shift assay protocol for evaluation of anti-infliximab antibodies. Application of the method to Crohn's disease patients treated with infliximab.

BACKGROUND: The availability of a quantitative method to measure anti-infliximab (IFX) antibodies (ATI) would facilitate the implementation of therapeutic drug monitoring in clinical decision-making. Our aim was to standardize the homogeneous mobility shift assay (HMSA) used in the measure of ATI levels. METHODS: In this prospective longitudinal multicenter study, 50 IFX-treated Crohn's disease (CD) patients were followed up for 54weeks. During this period 360 human serum samples were analysed. Monomeric ATI levels were measured by a quantitative HMSA-method using an anti-IFX calibrator. IFX trough levels measured by ELISA were correlated with ATI levels. RESULTS: Using HMSA and a pure anti-idiotypic monoclonal antibody specific for IFX (anti-IFX calibrator), we measured the levels of monomeric ATI generated in Crohn's disease patients treated with IFX. Anti-IFX calibrator allowed to quantify monomeric antibodies against IFX with a low limit of quantification (3nM). The threshold level of ATI in order to classify the immunogenicity of the patients was 10nM. We observed that 24% (12/50) of IFX-treated patients developed ATI (>10nM) during the observation period (54weeks). Serum concentration of ATI higher than 10nM dramatically increased the probability (OR=51.1; 95% CI: 20.4-128.0; p<0.0001) of presenting low levels of IFX (⩽1.5nM) in serum, as observed in some CD patients treated with standard doses of the drug. CONCLUSIONS: The HMSA-method described here allows an accurate quantification of ATI concentration in international units (IU) and therefore it could be useful in the study of the relationship between ATI concentration, infliximab level and the clinical response to the drug.

[Low back pain of unfavourable progression]. / Lumbalgia de evolución tórpida.

We present the case of a patient with chronic low back pain with an unfavourable progression despite the prescribed pharmacological treatment. The patient had symptoms associated with compression of the sciatic nerve in an atypical area. As it passed through the piriformis muscle, it was diagnosed as piriformis muscle syndrome. This diagnosis was based on the clinical signs and symptoms and the determination of the tests performed, with the imaging tests being absolutely normal. Treatment is basically with non-steroidal anti-inflammatory drugs, muscle relaxants and stretching exercises of this muscle.

Smoking does influence disease behaviour and impacts the need for therapy in Crohn's disease in the biologic era.

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.

Characteristics and treatment of pyoderma gangrenosum in inflammatory bowel disease.

BACKGROUND: Pyoderma gangrenosum is a serious cutaneous complication seen in approximately 1 % of patients with inflammatory bowel disease (IBD). Oral corticosteroids are the mainstay treatment, although the evidence supporting their use is weak. AIMS: The purpose of this study was to investigate the characteristics of pyoderma gangrenosum associated with Crohn's disease or ulcerative colitis and which treatments are prescribed in Spanish clinical practice. METHODS: In this retrospective, observational study, the medical records from all patients with IBD and a diagnosis of pyoderma gangrenosum attended by the gastroenterology departments of 12 Spanish hospitals were reviewed. Data on patient demographics and characteristics, underlying IBD and treatment, and pyoderma gangrenosum characteristics, treatment, and outcome were collected and analyzed. RESULTS: The data from 67 patients were analyzed (41 [61.2 %] women, 41 [61.2 %] with Crohn's disease, 25 [37.3 %] with ulcerative colitis, and 1 [1.5 %] with indeterminate disease). The underlying disease was in remission in approximately one-third of patients at the time of presentation of pyoderma gangrenosum. Healing was achieved in all patients (in 3 without any systemic therapy). Oral corticosteroids were taken by 51 patients (76.1 %), almost always as first-line treatment, although definitive healing was attained in 19 (28.4 %). Biologic agents such as infliximab and adalimumab were taken by 31 patients (46.3 %) at some point (first-line in 6 patients [9.0 %]), with definitive healing in 29 patients (93.5 %). CONCLUSIONS: Oral corticosteroid therapy remains the most common treatment for pyoderma gangrenosum associated with inflammatory bowel disease. Biologic therapies such as infliximab and adalimumab should also be considered.

[Hydrochlorothiazide induced bullous pemphigoid]. / Penfigoide ampolloso inducido por hidroclorotiazida.

We report the case of a 55 year-old man who consulted for pruritic bullous lesions of three months onset located on the body, hands and scalp. After ruling out various illnesses to justify the situation described, it was thought that the cause could be pharmacological. The patient had been on treatment with hydrochlorothiazide for several years due to hypertension. The lesions improved with the withdrawal of diuretic therapy, and the introduction of oral corticosteroids.

Enterocutaneous fistulas and Crohn´s disease: clinical characteristics and response to treatment.

INTRODUCTION: the low prevalence of enterocutaneous fistulas (ECF) in patients with Crohn´s disease (CD) justifies the scarcity of studies that analyze the effect of medical treatment and the need for surgery in these patients. The objective of this study was to evaluate the clinical characteristics of patients with CD who have ECF and the response to different treatments. MATERIALS AND METHODS: patients with CD who presented ECF fistula between 1970 and 2009 in three tertiary centers in Spain were analyzed retrospectively for their clinical characteristics, response to treatment as well as the correlation between the response to biological therapies for ECF and perianal disease. The inflammatory activity of the disease was measured using the Harvey-Bradshaw index. The definitions of partial or complete response were based on the treating physician´s judgment. RESULTS: twenty six patients were included (18 women); in more than half of cases (67%), anti-TNF treatment improved fistula drainage. Postoperative fistulas responded better to anti-TNF treatment than did spontaneous fistulas (80 versus 57%). One hundred percent and 60% of spontaneous and postoperative fistulas closed after surgery, respectively. CONCLUSIONS: although the majority of patients required surgery as the ultimate treatment, anti-TNF drugs improved fistula output in an acceptable percentage of patients who were treated. Therefore, this may be a treatment strategy prior to surgery in a select group of patients.

Safety of thiopurines and anti-TNF-α drugs during pregnancy in patients with inflammatory bowel disease.

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.

Comparison of the effectiveness of two protocols for vaccination (standard and double dosage) against hepatitis B virus in patients with inflammatory bowel disease.

BACKGROUND: The response rate to hepatitis B virus (HBV) vaccination in patients with inflammatory bowel disease (IBD) is low. AIM: To compare two vaccination protocols-the standard dose and the double dose-in IBD patients. METHODS: Patients diagnosed with IBD from three tertiary hospitals were vaccinated against HBV with two different protocols: the standard protocol (Engerix-B single dose at 0, 1 and 6 months) and the new faster protocol based on a double dose (Engerix B double dose at 0, 1 and 2 months). Anti-HBs titres were measured 1-3 months after the last dose. A multivariate analysis was performed to identify factors that were predictive of response to the vaccine. RESULTS: The study sample comprised 148 patients (mean age 40 years, 69% Crohn's disease), 70% of whom were receiving immunosuppressive therapy (22% thiopurines, 23% anti-TNF and 25% both). The standard protocol was followed in 46% of patients and the double dose protocol in 54%. Considering anti-HBs >10 IU/L as a successful response to vaccination, the seroconversion rate was higher among patients vaccinated with the double dose than with the standard dose: 75% (95% CI, 65-85%) vs. 41% (95% CI, 29-54%) (P < 0.001). In the multivariate analysis, vaccination with the double dose was the only factor associated with a better response to the vaccine (OR, 4; 95% CI, 2-8; P < 0.001). CONCLUSIONS: The response rate to the HBV vaccination in IBD patients is low. Administration of a double dose was associated with a higher response rate. Therefore, the double dose protocol could be a suitable option in patients with IBD.

Efficacy of infliximab rescue therapy in patients with chronic refractory pouchitis: a multicenter study.

BACKGROUND: Despite medical therapy, 30% of patients with ulcerative colitis (UC) need to undergo surgery. Around 50% of patients with proctocolectomy with ileal pouch-anal anastomosis (IPAA) develop complications of the pouch. Clinical evidence for the use of infliximab (IFX) in refractory pouchitis is limited. The aim of this study was to report efficacy of IFX in these patients. METHODS: A retrospective, multicenter study was designed. Patients older than 18 years with chronic refractory pouchitis treated with IFX (5 mg/kg) were included. Short-term IFX efficacy was evaluated at week 8 and mid-term efficacy at weeks 26 and 52. Complete response was defined as cessation of diarrhea and urgency and partial response as marked clinical improvement but persisting symptoms. The modified Pouchitis Disease Activity Index (mPDAI) without endoscopy was calculated when available. RESULTS: Thirty-three consecutive UC patients with chronic refractory pouchitis were included (18 male, mean age 45 years, range 21-67). At week 8, 21% patients achieved complete response and 63% showed partial clinical response. At weeks 26 and 52, 33% and 27% achieved complete response and 33% and 18% showed partial clinical response, respectively. Thirteen patients (39%) withdrew treatment (four for lack of efficacy, four for loss of response and five for adverse events). None of the potential factors analyzed had an influence on response to IFX. CONCLUSIONS: IFX was effective in the short- and mid-term in patients with chronic refractory pouchitis. However, medication had to be discontinued in a high number of patients.
