Sex-Related Differences in the Phenotype and Course of Inflammatory Bowel Disease: SEXEII Study of ENEIDA.

BACKGROUND & AIMS: The impact of patient sex on the presentation of inflammatory bowel disease (IBD) has been poorly evaluated. Our aims were to assess potential disparities in IBD phenotype and progression between sexes. METHODS: We performed an observational multicenter study that included patients with Crohn's disease (CD) or ulcerative colitis from the Spanish ENEIDA registry. Data extraction was conducted in July 2021. RESULTS: A total of 51,595 patients with IBD were included, 52% were males and 25,947 had CD. The median follow-up period after diagnosis was 9 years in males and 10 years in females. In CD, female sex was an independent risk factor for medium disease onset (age, 17-40 y) (relative risk ratio, 1.45; 95% CI, 1.31-1.62), later disease onset (age, >40 y) (relative risk ratio, 1.55; 95% CI, 1.38-1.73), exclusive colonic involvement (odds ratio, 1.24; 95% CI, 1.14-1.34), inflammatory behavior (odds ratio, 1.14; 95% CI, 1.07-1.21), and extraintestinal manifestations (odds ratio, 1.48; 95% CI, 1.38-1.59). However, female sex was a protective factor for upper gastrointestinal involvement (odds ratio, 0.84; 95% CI, 0.79-0.90), penetrating behavior (odds ratio, 0.76; 95% CI, 0.70-0.82), perianal disease (odds ratio, 0.77; 95% CI, 0.71-0.82), and complications (odds ratio, 0.73; 95% CI, 0.66-0.80). In ulcerative colitis, female sex was an independent risk factor for extraintestinal manifestations (odds ratio, 1.48; 95% CI, 1.26-1.61). However, female sex was an independent protective factor for disease onset from age 40 onward (relative risk ratio, 0.76; 95% CI, 0.66-0.87), left-sided colonic involvement (relative risk ratio, 0.72; 95% CI, 0.67-0.78), extensive colonic involvement (relative risk ratio, 0.59; 95% CI, 0.55-0.64), and abdominal surgery (odds ratio, 0.78; 95% CI, 0.69-0.88). CONCLUSIONS: There is sexual dimorphism in IBD. The patient's sex should be taken into account in the clinical management of the disease.

Position statement of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis on sexuality and inflammatory bowel disease. / Documento de posicionamiento. Recomendaciones del Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa sobre sexualidad y enfermedad inflamatoria intestinal.

It is widely acknowledged that inflammatory bowel disease (IBD) is associated with a high prevalence of sexual dysfunction (SD). However, there is a notable paucity of specific literature in this field. This lack of information impacts various aspects, including the understanding and comprehensive care of SD in the context of IBD. Furthermore, patients themselves express a lack of necessary attention in this area within the treatment of their disease, thus creating an unmet need in terms of their well-being. The aim of this position statement by the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) is to provide a review on the most relevant aspects and potential areas of improvement in the detection, assessment, and management of SD in patients with IBD and to integrate the approach to sexual health into our clinical practice. Recommendations are established based on available scientific evidence and expert opinion. The development of these recommendations by GETECCU has been carried out through a collaborative multidisciplinary approach involving gastroenterologists, gynecologists, urologists, surgeons, nurses, psychologists, sexologists, and, of course, patients with IBD.

The Risk of Developing Disabling Crohn's Disease: Validation of a Clinical Prediction Rule to Improve Treatment Decision Making.

BACKGROUND: Crohn's disease (CD) is characterized by the development of complications over the course of the disease. It is crucial to identify predictive factors of disabling disease, in order to target patients for early intervention. We evaluated risk factors of disabling CD and developed a prognostic model. METHODS: In total, 511 CD patients were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to identify demographic, clinical, and biological risk factors. A predictive nomogram model was developed in a subgroup of patients with noncomplicated CD (inflammatory pattern and no perianal disease). RESULTS: The rate of disabling CD within 5 years after diagnosis was 74.6%. Disabling disease was associated with gender, location of disease, requirement of steroids for the first flare, and perianal lesions. In the subgroup of patients (310) with noncomplicated CD, the rate of disabling CD was 80%. In the multivariate analysis age at onset <40 years (OR = 3.46, 95% confidence interval [CI] = 1.52-7.90), extensive disease (L3/L4) (OR = 2.67, 95% CI = 1.18-6.06), smoking habit (OR = 2.09, 95% CI = 1.03-4.27), requirement of steroids at the first flare (OR = 2.20, 95% CI = 1.09-4.45), and albumin (OR = 0.59, 95% CI = 0.36-0.96) were associated with development of disabling disease. The developed predictive nomogram based on these factors presented good discrimination, with an area under the receiver operating characteristic curve of 0.723 (95% CI: 0.670-0.830). CONCLUSION: We identified predictive factors of disabling CD and developed an easy-to-use prognostic model that may be used in clinical practice to help identify patients at high risk and address treatment effectively.

[Optimization of immunomodulatory treatment with azathioprine or 6-mercaptopurine in inflammatory bowel disease]. / Optimización del tratamiento inmunomodulador con azatioprina o 6-mercaptopurina en pacientes con enfermedad inflamatoria intestinal.

BACKGROUND: There is limited information on the optimal use of thiopurinic immunomodulators in inflammatory bowel disease (IBD) and the dosage, efficacy and toxicity of these drugs has not been clearly established. AIM: To evaluate clinical outcomes and the toxicity of thiopurinic immunomodulators in clinical practice (effectiveness), as well as possible associated variables. METHODS: Data were obtained from a database of patients with ulcerative colitis and Crohn's disease who started treatment with azathioprine or 6-mercaptopurine with an identical predetermined schedule and follow-up. Remission, relapse and toxicity were defined and analyzed and their relationship with clinical, biologic and demographic variables was evaluated with multivariate analysis. RESULTS: We evaluated 150 courses of treatment in 126 patients. Treatment was given to induce clinical remission in 118 courses and 62% of the patients reached this outcome, which was maintained for a mean of 52 months. The only variable associated with poor response was perianal disease. Adverse events were detected in 34% of the courses and were the main cause of treatment withdrawal. Factors significantly associated with withdrawal due to adverse events were starting with full doses of thiopurinic drugs (OR, 4.26; 95% CI, 1.12-16.32) and cotreatment with infliximab (OR, 5.6; 95% CI, 1.17-27.1). CONCLUSIONS: Some clinical variables such as disease phenotype, the use of full doses of thiopurinic drugs from the start of treatment, and co-treatments can have a notable influence on adverse effects and thus on the effectiveness of this therapy in IBD.

Serum Adalimumab Levels Predict Successful Remission and Safe Deintensification in Inflammatory Bowel Disease Patients in Clinical Practice.

BACKGROUND: Little is known about the association between the pharmacokinetic features of adalimumab (ADL) and disease outcome in patients with inflammatory bowel disease (IBD). AIMS: To assess the association between random serum ADL levels and clinical or biochemical remission with clinical decision making in daily practice according to these levels; and to determine the cutoff value for successful dose reduction in patients with IBD treated with ADL. METHODS: We conducted a prospective observational study of patients with IBD who received long-term maintenance therapy with ADL. RESULTS: Data were available for 157 serum samples from 87 patients. Serum ADL levels were associated with clinical remission: median 9.2 versus 6.0 µg/mL for patients with Crohn's disease with active disease (P = 0.009) and 14.4 versus 5.2 µg/mL in patients with ulcerative colitis with active disease (P = 0.002). Serum ADL levels were 9.2 µg/mL for patients with a normal C-reactive protein value (<5 mg/L) and 5.2 µg/mL for patients with a high C-reactive protein value (P = 0.002). ADL levels were significantly associated with normal fecal calprotectin value (<80 ng/g) (10.8 versus 7.6 µg/mL, respectively, P = 0.038). Serum ADL levels were significantly associated with successful deintensification, over a 6-month period of clinical follow-up, compared with the group in which doses remained unchanged (area under the curve 0.88; 95% confidence interval, 0.81-0.95; P < 0.001), with a cutoff value for successful deintensification of 12.2 µg/mL. CONCLUSIONS: Higher ADA levels were significantly associated with clinical and biochemical remission. Our results, which were obtained under conditions of daily clinical practice, suggest that an ADL cutoff of 12.2 µg/mL could be appropriate for successful dose reduction in patients with IBD treated with ADL.

Telemedicine in inflammatory bowel disease: opportunities and approaches.

This review article summarizes the evidence about telemedicine applications (e.g., telemonitoring, teleconsulting, and tele-education) in the management of patients with inflammatory bowel disease (IBD), and we aim to give an overview of the acceptance and impact of these interventions on health outcomes. Based on the literature search on "inflammatory bowel disease," "Crohn's disease" and "ulcerative colitis" in combination with "e-health," "telemedicine," and "telemanagement," we selected 58 titles and abstracts published up to June 2014 and searched in PubMed, EMBASE, MEDLINE, Cochrane Database, Web of Science and Conference Proceedings. Titles and abstracts were screened for a set of inclusion criteria: e-health intervention, IBD as the main disease, and a primary study performed. Finally, 16 were included for full reading, data extraction, and critical appraisal of the evaluation. Most studies use telemonitoring (home telemanagement system or web portal) and telecare (real-time telephone and image) as telemedicine applications and assessed the feasibility and acceptance of these systems, adherence to treatment, quality of life, and patient knowledge, particularly in patients with ulcerative colitis. Furthermore, some of these studies evaluated the patients' empowerment, health care costs, and safety of telemonitoring in IBD. In conclusion, the health outcomes of telemedicine applications in IBD suggest that these could be implemented in clinical practice because they are safe and feasible applications that are well accepted by the patient and improve adherence, quality of life, and disease knowledge. Further studies with large sample sizes and complex diseases are needed to confirm these results.
