Clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in patients with ulcerative colitis treated with two consecutive anti-TNF agents: data from the ENEIDA registry.

Background: Infliximab seems to be the most efficacious of the three available anti-TNF agents for ulcerative colitis (UC) but little is known when it is used as the second anti-TNF. Objectives: To compare the clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in UC patients. Design: Retrospective observational study. Methods: Patients from the ENEIDA registry treated consecutively with infliximab and a subcutaneous anti-TNF (or vice versa), naïve to other biological agents, were identified and grouped according to the administration route of the first anti-TNF into IVi (intravenous initially) or SCi (subcutaneous initially). Results: Overall, 473 UC patients were included (330 IVi and 143 SCi). Clinical response at week 14 was 42.7% and 48.3% in the IVi and SCi groups (non-statistically significant), respectively. Clinical remission rates at week 52 were 32.8% and 31.4% in the IVi and SCi groups (nonsignificant differences), respectively. A propensity-matched score analysis showed a higher clinical response rate at week 14 in the SCi group and higher treatment persistence in the IVi group. Regarding long-term outcomes, dose escalation and discontinuation due to the primary failure of the first anti-TNF and more severe disease activity at the beginning of the second anti-TNF were inversely associated with clinical remission. Conclusion: The use of a second anti-TNF for UC seems to be reasonable in terms of efficacy, although it is particularly reduced in the case of the primary failure of the first anti-TNF. Whether the second anti-TNF is infliximab or subcutaneous does not seem to affect efficacy.

Serum and Urine Metabolomic Profiling of Newly Diagnosed Treatment-Naïve Inflammatory Bowel Disease Patients.

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) is a prevalent chronic noncurable disease associated with profound metabolic changes. The discovery of novel molecular indicators for unraveling IBD etiopathogenesis and the diagnosis and prognosis of IBD is therefore pivotal. We sought to determine the distinctive metabolic signatures from the different IBD subgroups before treatment initiation. METHODS: Serum and urine samples from newly diagnosed treatment-naïve IBD patients and age and sex-matched healthy control (HC) individuals were investigated using proton nuclear magnetic resonance spectroscopy. Metabolic differences were identified based on univariate and multivariate statistical analyses. RESULTS: A total of 137 Crohn's disease patients, 202 ulcerative colitis patients, and 338 HC individuals were included. In the IBD cohort, several distinguishable metabolites were detected within each subgroup comparison. Most of the differences revealed alterations in energy and amino acid metabolism in IBD patients, with an increased demand of the body for energy mainly through the ketone bodies. As compared with HC individuals, differences in metabolites were more marked and numerous in Crohn's disease than in ulcerative colitis patients, and in serum than in urine. In addition, clustering analysis revealed 3 distinct patient profiles with notable differences among them based on the analysis of their clinical, anthropometric, and metabolomic variables. However, relevant phenotypical differences were not found among these 3 clusters. CONCLUSIONS: This study highlights the molecular alterations present within the different subgroups of newly diagnosed treatment-naïve IBD patients. The metabolomic profile of these patients may provide further understanding of pathogenic mechanisms of IBD subgroups. Serum metabotype seemed to be especially sensitive to the onset of IBD.

Ustekinumab and vedolizumab for the prevention of postoperative recurrence of Crohn's disease: Results from the ENEIDA registry.

BACKGROUND: Anti-TNF agents are the only effective biological agents for the prevention of postoperative recurrence (POR) in Crohn's disease (CD). However, they are contraindicated or have been shown to fail in some patients. Although ustekinumab and vedolizumab were licensed for CD some years ago, data in this setting are scarce. METHODS: All CD patients in whom ustekinumab or vedolizumab was prescribed for the prevention of POR within three months of ileocolonic resection with anastomosis were identified from the ENEIDA registry. The development of endoscopic, clinical and surgical POR was registered. RESULTS: Forty patients were treated for the prevention of POR with ustekinumab and 25 were treated with vedolizumab. Eighty per cent had at least one risk factor for POR (prior resections, active smoking, perianal disease or penetrating disease behaviour). All the patients had been exposed to anti-TNF therapy. After a median follow-up of 17 and 26 months, the cumulative probability of clinical POR at 12 months after surgery was 32% and 30% for ustekinumab and vedolizumab, respectively. Endoscopic assessment within the first 18 months after surgery was available for 80% of the patients on ustekinumab and 70% for those on vedolizumab. The rate of endoscopic POR was 42% for ustekinumab and 40% for vedolizumab. One patient treated with ustekinumab and two with vedolizumab underwent a new intestinal resection. CONCLUSIONS: Ustekinumab and vedolizumab seem to be effective in the prevention of POR in patients at high risk. Our results warrant controlled trials comparing these drugs with conventional therapies.

Immigrant IBD Patients in Spain Are Younger, Have More Extraintestinal Manifestations and Use More Biologics Than Native Patients.

BACKGROUND: Previous studies comparing immigrant ethnic groups and native patients with IBD have yielded clinical and phenotypic differences. To date, no study has focused on the immigrant IBD population in Spain. METHODS: Prospective, observational, multicenter study comparing cohorts of IBD patients from ENEIDA-registry who were born outside Spain with a cohort of native patients. RESULTS: We included 13,524 patients (1,864 immigrant and 11,660 native). The immigrants were younger (45 ± 12 vs. 54 ± 16 years, p < 0.001), had been diagnosed younger (31 ± 12 vs. 36 ± 15 years, p < 0.001), and had a shorter disease duration (14 ± 7 vs. 18 ± 8 years, p < 0.001) than native patients. Family history of IBD (9 vs. 14%, p < 0.001) and smoking (30 vs. 40%, p < 0.001) were more frequent among native patients. The most prevalent ethnic groups among immigrants were Caucasian (41.5%), followed by Latin American (30.8%), Arab (18.3%), and Asian (6.7%). Extraintestinal manifestations, mainly musculoskeletal affections, were more frequent in immigrants (19 vs. 11%, p < 0.001). Use of biologics, mainly anti-TNF, was greater in immigrants (36 vs. 29%, p < 0.001). The risk of having extraintestinal manifestations [OR: 2.23 (1.92-2.58, p < 0.001)] and using biologics [OR: 1.13 (1.0-1.26, p = 0.042)] was independently associated with immigrant status in the multivariate analyses. CONCLUSIONS: Compared with native-born patients, first-generation-immigrant IBD patients in Spain were younger at disease onset and showed an increased risk of having extraintestinal manifestations and using biologics. Our study suggests a featured phenotype of immigrant IBD patients in Spain, and constitutes a new landmark in the epidemiological characterization of immigrant IBD populations in Southern Europe.

Psychosocial impact of the COVID-19 pandemic on patients with inflammatory bowel disease in Spain. A post lockdown reflection.

OBJECTIVES: This multicenter cross-sectional study was conducted to assess the psychosocial impact of COVID-19 on patients with inflammatory bowel disease (IBD) in Spain during lockdown and the first wave of the pandemic. PATIENTS AND METHODS: A self-report questionnaire that integrated the Spanish version of the Depression, Anxiety and Stress Scale-21 items (DASS-21) and the Perceived Stress Questionnaire (PSS) was designed to gather sociodemographic data and information related to the effects of lockdown on the lives of IBD patients. Twelve IBD units invited their patients to answer the anonymous online survey between the 1st July and the 25th August 2020. RESULTS: Of the 693 survey participants with IBD, 67% were women and the mean age was 43 (SD 12). Sixty-one percent had ulcerative colitis, 36% Crohn's disease and 3% indeterminate colitis. DASS-21 scores indicate that during lockdown the estimated prevalence of depression was 11% [95% CI 8.2-13%], anxiety 20% [95% CI 17 to 23%] and stress 18% [95% CI 8.2-13%]. Multivariate analysis showed that the perceived high risk of COVID-19 infection because of having IBD and maladaptation to government measures to reduce the spread of disease doubled the risk of anxiety and stress during lockdown. CONCLUSIONS: In the short-term, lockdown during the COVID-19 pandemic seemed to have an impact on the already affected mental health of our IBD patients in Spain.

Risk of Immunomediated Adverse Events and Loss of Response to Infliximab in Elderly Patients with Inflammatory Bowel Disease: A Cohort Study of the ENEIDA Registry.

BACKGROUND AND AIMS: Immunomediated adverse events [IAEs] are the most frequently reported infliximab [IFX]-related adverse events. Combination therapy may reduce their incidence, although this strategy is not recommended in elderly patients. We aimed to compare the rates of IFX-related IAEs and loss of response [LOR] in elderly and younger patients. METHODS: Adult patients in the ENEIDA registry who had received a first course of IFX therapy were identified and grouped into two cohorts regarding age at the beginning of treatment [over 60 years and between 18 and 50 years]. The rates of IAEs and LOR were compared. RESULTS: In total, 939 patients [12%] who started IFX over 60 years of age and 6844 [88%] below 50 years of age were included. Elderly patients presented a higher proportion of AEs related to IFX [23.2% vs 19%; p = 0.002], infections [7.1% vs 4.3%; p < 0.001] and neoplasms [2.2% vs 0.5%; p < 0.001]. In contrast, the rates of IAEs [14.8% vs 14.8%; p = 0.999], infusion reactions [8.1% vs 8.1%; p = 0.989], late hypersensitivity [1.3% vs 1.2%; p = 0.895], paradoxical psoriasis [1% vs 1.5%; p = 0.187] and drug-induced lupus erythematosus [0.6% vs 0.7%; p = 0.947] were similar in elderly and younger patients. LOR rates were also similar between the two groups [20.5% vs 19.3%; p = 0.438]. In the logistic regression analysis, IFX monotherapy, extraintestinal manifestations and female gender were the only risk factors for IAEs, whereas IFX monotherapy, extraintestinal manifestations and Crohn's disease were risk factors for LOR. CONCLUSIONS: Elderly patients with inflammatory bowel disease have a similar risk of developing IFX-related IAEs and LOR to that of younger patients.

Effectiveness and Safety of Ustekinumab in Ulcerative Colitis: Real-world Evidence from the ENEIDA Registry.

BACKGROUND AND AIMS: The development programm UNIFI has shown promising results of ustekinumab in ulcerative colitis [UC] treatment which should be confirmed in clinical practice. We aimed to evaluate the durability, effectiveness, and safety of ustekinumab in UC in real life. METHODS: Patients included in the prospectively maintained ENEIDA registry, who received at least one intravenous dose of ustekinumab due to active UC [Partial Mayo Score [PMS]>2], were included. Clinical activity and effectiveness were defined based on PMS. Short-term response was assessed at Week 16. RESULTS: A total of 95 patients were included. At Week 16, 53% of patients had response [including 35% of patients in remission]. In the multivariate analysis, elevated serum C-reactive protein was the only variable significantly associated with lower likelihood of achieving remission. Remission was achieved in 39% and 33% of patients at Weeks 24 and 52, respectively; 36% of patients discontinued the treatment with ustekinumab during a median follow-up of 31 weeks. The probability of maintaining ustekinumab treatment was 87% at Week 16, 63% at Week 56, and 59% at Week 72; primary failure was the main reason for ustekinumab discontinuation. No variable was associated with risk of discontinuation. Three patients reported adverse events; one of them had a fatal severe SARS-CoV-2 infection. CONCLUSIONS: Ustekinumab is effective in both the short and the long term in real life, even in a highly refractory cohort. Higher inflammatory burden at baseline correlated with lower probability of achieving remission. Safety was consistent with the known profile of ustekinumab.

Preferences and satisfaction of IBD patients after switching from adalimumab 40 mg weekly to 80 mg every other week given as a single injection: the ADASCAL study.

BACKGROUND: A recently registered device containing 80 mg of adalimumab (ADA) allows an alternative dose escalation regimen with ADA 80 mg every other week (EOW) given as a single subcutaneous injection instead of 40 mg every week. The ADASCAL study evaluated the preferences and satisfaction of inflammatory bowel disease (IBD) patients after switching their ADA regimen from 40 mg weekly to 80 mg EOW given with a single-dose pen. METHODS: In this multicentre cross-sectional study, patients in whom the ADA regimen was changed from 40 mg weekly to 80 mg EOW completed the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4), a four-item questionnaire [a Likert-type 5-point scale for preferences, two closed questions for convenience and a 100-point visual analogue scale (VAS) to assess which escalated ADA regimen patients would prefer to continue] and two Health-Related Quality of Life (HRQoL) questionnaires: the generic European Quality of Life-5 Dimensions (EQ-5D) and disease-specific Spanish version of the Inflammatory Bowel Disease Questionnaire (SIBDQ-9). RESULTS: In total, 77 patients (64 Crohn's disease and 13 ulcerative colitis) were included. The TSQM score showed a notably high global satisfaction [83.4, standard deviation (SD) = 14.1] of patients with ADA 80 mg EOW given with a single-dose pen, with high TSQM scores for individual components: effectiveness (77.6, SD = 16.9), convenience (83.7, SD = 14.5) and side effects (86.1, SD = 23.4). Most of the patients (74%) preferred the ADA EOW regimen (59.7% had strong preference, 14.3% slight preference). ADA EOW interferes less with daily activity (59.7%) and with travel plans (81.8%). Most patients (77%) would prefer to continue with ADA EOW (mean VAS score of 84.7, SD = 24.1, where 100 indicates a preference for ADA EOW). Patients reported high HRQoL scores on both the EQ-5D (72.3, SD = 20.1) and SIBDQ-9 (75.1, SD = 14.7). CONCLUSION: IBD patients in whom the ADA regimen was changed from 40 mg weekly to 80 mg EOW reported a higher preference for the EOW regimen and therefore most decided to continue with a single self-injection EOW.

Extraintestinal Manifestations in Patients with Inflammatory Bowel Disease: Study Based on the ENEIDA Registry.

BACKGROUND: Patients with inflammatory bowel disease (IBD) may present extraintestinal manifestations (EIMs) that affect the joints, skin, eyes, and hepatobiliary area, among others. AIMS: Our aim was to analyse the prevalence and characteristics of EIMs in patients with IBD and to identify the possible risk factors associated with the development of EIMs in the largest series published to date. METHODS: Observational, cross-sectional study including patients from the Spanish ENEIDA registry promoted by GETECCU. We retrospectively identified all cases of EIMs in the ENEIDA registry until January 2018. RESULTS: The study included 31,077 patients, 5779 of whom had at least one EIM (global prevalence 19%; 95% CI 18.2-19.0). Among the different types of EIMs, rheumatic manifestations had a prevalence of 13% (95% CI 12.9-13.7; 63% of EIMs), with a prevalence of 5% (95% CI 4.7-5.2) for mucocutaneous manifestations, 2.1% (95% CI 1.9-2.2) for ocular manifestations, and 0.7% (95% CI 0.6-0.8) for hepatobiliary manifestations. The multivariable analysis showed that the type of IBD (Crohn's disease, p < 0.001), gender (female, p < 0.001), the need for an immunomodulator (p < 0.001) or biologic drugs (p < 0.001), a previous family history of IBD (p < 0.001), and an extensive location of IBD (p < 0.001) were risk factors for the presence of EIMs. CONCLUSIONS: One-fifth of patients with IBD may have associated EIMs, with rheumatic manifestations as the most frequent (> 60% of EIMs). Female patients with severe Crohn's disease represent the group with the highest risk of developing EIMs. These patients should therefore be specially monitored and referred to the corresponding specialist when suggestive symptoms appear.

Effects of anti-TNF-alpha therapy on hemoglobin levels and anemia in patients with inflammatory bowel disease.

BACKGROUND: Tumor necrosis factor-α (TNF-α) is involved in inducing inflammatory anemia. The potential effect of anti-TNF-α agents on anemia in inflammatory bowel diseases (IBD) is still unknown. METHODS: Analytical data and disease characteristics from 362 IBD patients [271 CD/91UC) treated with anti-TNF-α drugs were retrospectively collected. Effects on disease activity, blood markers and prevalence of anemia were assessed after 6 and 12 months of therapy. RESULTS: 29.3% patients presented anemia at baseline, and significantly reduced to 14.4% and 7.8% after 6 and 12 months of therapy, respectively. Mean ±â€¯SD Hb levels increased significantly at month 6, and this increase was sustained at 12 months. Serum markers of iron metabolism increased significantly compared to baseline, as disease activity measured by C-reactive protein (CRP) was reduced. All these effects were observed independently for CD and UC, and were independent of iron supplementation during treatment. Anemia at baseline (OR 4.09; 95%CI 1.98-8.45) and elevated CRP (OR 3.45; 95CI 1.29-9.22) were independently associated with risk of persistent anemia, as well as iron replacement during therapy (OR 4.36; 95%CI 2.07-9.16). CONCLUSIONS: Controlling disease activity with anti-TNF- α therapy significantly and independently associated with resolution of anemia in IBD, with no relevant role for iron replacement therapy.

Effectiveness and Safety of the Sequential Use of a Second and Third Anti-TNF Agent in Patients With Inflammatory Bowel Disease: Results From the Eneida Registry.

BACKGROUND: The effectiveness of the switch to another anti-tumor necrosis factor (anti-TNF) agent is not known. The aim of this study was to analyze the effectiveness and safety of treatment with a second and third anti-TNF drug after intolerance to or failure of a previous anti-TNF agent in inflammatory bowel disease (IBD) patients. METHODS: We included patients diagnosed with IBD from the ENEIDA registry who received another anti-TNF after intolerance to or failure of a prior anti-TNF agent. RESULTS: A total of 1122 patients were included. In the short term, remission was achieved in 55% of the patients with the second anti-TNF. The incidence of loss of response was 19% per patient-year with the second anti-TNF. Combination therapy (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.8-3; P < 0.0001) and ulcerative colitis vs Crohn's disease (HR, 1.6; 95% CI, 1.1-2.1; P = 0.005) were associated with a higher probability of loss of response. Fifteen percent of the patients had adverse events, and 10% had to discontinue the second anti-TNF. Of the 71 patients who received a third anti-TNF, 55% achieved remission. The incidence of loss of response was 22% per patient-year with a third anti-TNF. Adverse events occurred in 7 patients (11%), but only 1 stopped the drug. CONCLUSIONS: Approximately half of the patients who received a second anti-TNF achieved remission; nevertheless, a significant proportion of them subsequently lost response. Combination therapy and type of IBD were associated with loss of response. Remission was achieved in almost 50% of patients who received a third anti-TNF; nevertheless, a significant proportion of them subsequently lost response.

EpidemIBD: rationale and design of a large-scale epidemiological study of inflammatory bowel disease in Spain.

BACKGROUND: Inflammatory bowel disease (IBD) is associated with a considerable burden to the patient and society. However, current data on IBD incidence and burden are limited because of the paucity of nationwide epidemiological studies, heterogeneous designs, and a low number of participating centers and sample size. The EpidemIBD study is a large-scale investigation to provide an accurate assessment of the incidence of IBD in Spain, as well as treatment patterns and outcomes. METHODS: This multicenter, population-based incidence cohort study included patients aged >18 years with IBD (Crohn's disease, ulcerative colitis, or unclassified IBD) diagnosed during 2017 in 108 hospitals in Spain, covering 50% of the Spanish population. Each participating patient will attend 10 clinic visits during 5 years of follow up. Demographic data, IBD characteristics and family history, complications, treatments, surgeries, and hospital admissions will be recorded. RESULTS: The EpidemIBD study is the first large-scale nationwide study to investigate the incidence of IBD in Spain. Enrollment is now completed and 3627 patients are currently being followed up. CONCLUSIONS: The study has been designed to overcome many of the limitations of previous European studies into IBD incidence by prospectively recruiting a large number of patients from all regions of Spain. In addition to epidemiological information about the burden of IBD, the 5-year follow-up period will also provide information on treatment patterns, and the natural history and financial burden of IBD.

Fecal calprotectin is not superior to serum C-reactive protein or the Harvey-Bradshaw index in predicting postoperative endoscopic recurrence in Crohn's disease.

BACKGROUND: Fecal calprotectin (FC) is a widely used noninvasive marker of gut inflammation that is associated with endoscopic severity in Crohn's disease (CD). However, FC has been inconsistent in predicting postoperative recurrence of CD, and its utility in the postoperative setting remains unclear. MATERIALS AND METHODS: Blood and fecal samples were collected in consecutively recruited patients with CD who had undergone ileocolonic resection and required a colonoscopy to assess postoperative recurrence, as defined by the Rutgeerts score (RS). RESULTS: A total of 86 patients were prospectively recruited at five centers. Overall, 49 (57%) had CD recurrence (RS≥i2). FC concentrations trended to increase with RS severity; FC median (interquartile range) was significantly higher in patients with endoscopic recurrence than those in endoscopic remission [172.5 (75-375) vs. 75 (36.5-180.5) µg/g, respectively]. The same occurred for C-reactive protein (CRP) [0.5 (0.1-0.95) vs. 0.1 (0.02-0.27)] mg/dl and the Harvey-Bradshaw index (HBI) [4 (2-7) vs. 1 (0-3.5)]. The three variables significantly correlated. The area under the curve to discriminate between patients in endoscopic remission and recurrence was 0.698 for FC, with 62 µg/g being the optimal cut-off point. This indicated FC would have 85.7% sensitivity and 45.9% specificity in detecting any recurrence, having positive predictive value and negative predictive value of 67.7 and 70.8%, respectively. Area under the curve for CRP and HBI were both 0.710. The combination of CRP and HBI provided a positive predictive value 95.7 and a diagnostic odds ratio of 30.8. CONCLUSION: FC is not better than CRP combined with HBI to predict endoscopic postoperative recurrence of CD.

Short and long-term effectiveness and safety of vedolizumab in inflammatory bowel disease: results from the ENEIDA registry.

BACKGROUND: Effectiveness of vedolizumab in real world clinical practice is unknown. AIM: To evaluate the short and long-term effectiveness of vedolizumab in patients with inflammatory bowel disease (IBD). METHODS: Patients who received at least 1 induction dose of vedolizumab were included. Effectiveness was defined based on Harvey-Bradshaw index (HBI) in Crohn's disease (CD) and Partial Mayo Score (PMS) in ulcerative colitis (UC). Short-term response was assessed at week 14. Variables associated with short-term remission were identified by logistic regression analysis. The Kaplan-Meier method was used to evaluate the long-term durability of vedolizumab treatment. Cox model was used to identify factors associated with discontinuation of treatment and loss of response. RESULTS: 521 patients were included (median follow-up 10 months [interquartile range 5-18 months]). At week 14, 46.8% had remission and 15.7% clinical response. CD (vs UC), previous surgery, higher CRP concentration and disease severity at baseline were significantly associated with impaired response. The rate of vedolizumab discontinuation was 37% per patient-year of follow-up (27.6% in UC and 45.3% in CD, P < 0.01). CD (vs UC), anaemia at baseline, steroids during induction and CRP concentration were associated with lower durability of treatment. Seven per cent of patients developed adverse events, infections being the most frequent. CONCLUSIONS: Over 60% of IBD patients respond to vedolizumab. Many patients discontinue treatment over time. CD and disease burden impair both short- and long-term response. Vedolizumab seems to be safe in clinical practice.

Anemia at the time of diagnosis of inflammatory bowel disease: Prevalence and associated factors in adolescent and adult patients.

BACKGROUND: The prevalence, characteristic and determinants of anemia, at the time of inflammatory bowel disease (IBD) diagnosis have yet to be fully elucidated. METHODS: Retrospective cross-sectional study. Analytical data and disease characteristics obtained upon diagnosis of 1278 IBD patients [Crohn's disease/ulcerative colitis (CD/UC): 718/560] were collected. RESULTS: Anemia was present in 41.2% of patients at diagnosis (47% and 33.8% of CD and UC patients, respectively; p<0.001), being severe in 5.5%. Iron deficiency anemia represented 69.6% of cases, with no differences between CD and UC. Female sex was the strongest risk factor for anemia in both CD and UC (OR 7.11; 95%CI 4.18-12.10 and 6.55; 95%CI 3.39-12.63, respectively), followed by elevated (≥2mg/dL) C-reactive protein (OR 4.08; 95%CI 2.39-6.97 and 4.58; 95%CI 2.26-9.27, respectively). Current smoking was a risk factor for anemia in CD (OR 2.23; 95%CI 1.24-4.02), but a protective one in UC (OR 0.36; 95%CI 0.14-0.92). A penetrating CD behavior increased the risk of anemia (OR 3.34; 95%CI 1.36-8.21); in UC, anemia increased with disease extension (E2+E3) (OR 1.80; 95%CI 1.13-2.86). CONCLUSIONS: Female sex and disease activity are major determinants of anemia at IBD diagnosis. Anemia is associated with disease behavior in CD and with disease extension in UC.

Incidence, Clinical Characteristics, and Management of Psoriasis Induced by Anti-TNF Therapy in Patients with Inflammatory Bowel Disease: A Nationwide Cohort Study.

BACKGROUND: Psoriasis induced by anti-tumor necrosis factor-α (TNF) therapy has been described as a paradoxical side effect. AIM: To determine the incidence, clinical characteristics, and management of psoriasis induced by anti-TNF therapy in a large nationwide cohort of inflammatory bowel disease patients. METHODS: Patients with inflammatory bowel disease were identified from the Spanish prospectively maintained Estudio Nacional en Enfermedad Inflamatoria Intestinal sobre Determinantes genéticos y Ambientales registry of Grupo Español de Trabajo en Enfermedad de Croh y Colitis Ulcerosa. Patients who developed psoriasis by anti-TNF drugs were the cases, whereas patients treated with anti-TNFs without psoriasis were controls. Cox regression analysis was performed to identify predictive factors. RESULTS: Anti-TNF-induced psoriasis was reported in 125 of 7415 patients treated with anti-TNFs (1.7%; 95% CI, 1.4-2). The incidence rate of psoriasis is 0.5% (95% CI, 0.4-0.6) per patient-year. In the multivariate analysis, the female sex (HR 1.9; 95% CI, 1.3-2.9) and being a smoker/former smoker (HR 2.1; 95% CI, 1.4-3.3) were associated with an increased risk of psoriasis. The age at start of anti-TNF therapy, type of inflammatory bowel disease, Montreal Classification, and first anti-TNF drug used were not associated with the risk of psoriasis. Topical steroids were the most frequent treatment (70%), achieving clinical response in 78% of patients. Patients switching to another anti-TNF agent resulted in 60% presenting recurrence of psoriasis. In 45 patients (37%), the anti-TNF therapy had to be definitely withdrawn. CONCLUSIONS: The incidence rate of psoriasis induced by anti-TNF therapy is higher in women and in smokers/former smokers. In most patients, skin lesions were controlled with topical steroids. More than half of patients switching to another anti-TNF agent had recurrence of psoriasis. In most patients, the anti-TNF therapy could be maintained.

Epidemiology and temporal trends (2000-2012) of inflammatory bowel disease in adult patients in a central region of Spain.

BACKGROUND AND AIM: A growing incidence of inflammatory bowel disease (IBD) has been reported recently in southern Europe, with records of pediatric cases confirming these tendencies in Spain. Data on adult populations, however, have not been provided for over 10 years and need to be updated. PATIENTS AND METHODS: A multicenter retrospective registry of all adult patients with a diagnosis of IBD, including both Crohn's disease (CD) and ulcerative colitis (UC), attending five public hospitals covering a population of 514 368 inhabitants, was assessed. RESULTS: In 2012, the prevalence of CD and UC in adults was 137.17/100 000 inhabitants (95% confidence interval 114-160) and 99.84/100 000 inhabitants (95% confidence interval 79-119), respectively. The mean incidence rate during the period 2000-2012 of CD and UC was 8.9 and 5.6/100 000 inhabitants per year, respectively. Most of our patients (75.55%) had been diagnosed during the last 13 years. CD affected both sexes equally; a trend toward a progressive increase in the age at diagnosis, ileal location, and inflammatory behavior was documented for CD patients. In contrast, UC affected male patients with a higher frequency (57.8%; P=0.015), specifically those older than 40 years of age. Age at UC onset tended to increase progressively from 2000 to 2012 (P<0.001), but the extension on the disease remained unchanged. CONCLUSION: IBD is a highly prevalent disorder in our region, reaching the incidence of CD similar to the figures provided for Northern Europe. Changes in IBD localization, behavior, and age at diagnosis were documented during the period 2000-2012.
