EVALUATION OF THE SENSITIVITY AND SPECIFICITY OF SIGMOIDOSCOPY IN COMPARISON TO COLONOSCOPY REGARDING THE DETECTION OF INTESTINAL INFLAMMATORY ACTIVITY IN THE FOLLOW-UP OF PATIENTS WITH ULCERATIVE COLITIS.

INTRODUCTION: Ulcerative colitis (UC) is a chronic disease characterized by periods of inflammatory activity and remission, which vary from the rectum to the proximal colon. Currently, mucosal healing is a long-term goal in the management of inflammatory bowel disease, with colonoscopy and sigmoidoscopy being the recommended tools for evaluation. OBJECTIVE: To assess the effectiveness of both examinations in determining the presence of inflammatory activity in the follow-up of patients with UC. METHODS: Retrospective observational study analyzing colonoscopies performed as part of the follow-up of UC patients between January 2021 and July 2023 by gastroenterologists from the Inflammatory Bowel Disease Program at the Clínica Universidad de los Andes. The study compared endoscopic and histological activity observed in the rectosigmoid region with that found in the rest of the colon. Sensitivity and specificity were determined using concordance and correlations tests. RESULTS: A very good concordance and correlation were observed regarding endoscopic findings, with a Kappa index of 0,97 and a Spearman coefficient of 0,97. The Positive Predictive Value (PPV) of sigmoidoscopy for endoscopic activity was 1, and the Negative Predictive Value (NPV) was 0,96. In relation to histological activity, the concordance had a Kappa index of 0,93 and a Spearman coefficient of 0,93, with a PPV of sigmoidoscopy for histological activity being 1 and an NPV of 0,91. CONCLUSION: This cohort suggests that sigmoidoscopy is a cost-effective option for evaluating mucosal healing in UC patients in symptomatic and biomarker remission. However, complete colonoscopy should be considered in cases of discrepancies with the clinical picture or in colorectal cancer surveillance.

Selective granulocyte-monocyte apheresis during induction with vedolizumab in moderate-severe ulcerative colitis: Experience in a tertiary hospital.

AIM: Granulocyte and monocyte apheresis (GMA) is a potential therapeutic option when combined with various drugs for treatment of ulcerative colitis (UC). In this study, we analyze the efficacy and safety of GMA combined with vedolizumab (VDZ) during induction in patients with moderate-severe UC and incomplete response to steroids. PATIENTS AND METHODS: Single-center retrospective review of patients receiving GMA+VDZ. Data on the disease and previous treatments were collected. Clinical response was classified as no response, response without remission, and remission. Available data on biochemical and endoscopic response were included. Adverse events (AEs) were recorded. RESULTS: The study population comprised 6 patients with UC who had received GMA+VDZ during induction after failure of an anti-TNF agent. The median number of GMA sessions was 5 (IQR 4-5; 3-10). All the patients received VDZ 300mg iv at 0, 2, and 6 weeks, and 5 (83%) received an additional dose at week 10. During maintenance, all the patients continued VDZ iv every 8 weeks. The median follow-up was 57.6 months (IQR: 39-74). Four of the 6 patients achieved clinical remission after GMA+VDZ and continued in deep remission until the end of follow-up. A median, non-significant decrease of 1378µg/g (IQR: 924-5778µg/g) was observed for calprotectin and 42.2mg/l (IQR: 15.3-113.5) for CRP vs. baseline. No patient underwent colectomy. No treatment-related AEs were observed. CONCLUSIONS: GMA+VDZ during induction can be effective and safe in selected patients with moderate-severe UC and partial response to steroids.

Granulocyte and monocyte adsorptive apheresis (GMA) in patients with inflammatory bowel disease: A useful therapeutic tool not just in ulcerative colitis but also in Crohn's disease.

INTRODUCTION: Granulocyte and monocyte adsorptive apheresis (GMA) removes neutrophils and monocytes from peripheral blood, preventing their incorporation into the inflamed tissue also influencing cytokine balance. Published therapeutic efficacy in ulcerative colitis (UC) is more consistent than in Crohn's disease (CD). We assessed clinical efficacy of GMA in UC and CD 4 weeks after last induction session, at 3 and 12 months, sustained remission and corticosteroid-free remission. PATIENTS AND METHOD: Retrospective observational study of UC and CD patients treated with GMA. Partial Disease Activity Index-DAIp in UC and Harvey-Bradshaw Index-HBI in CD assessed efficacy of Adacolumn® with induction and optional maintenance sessions. RESULTS: We treated 87 patients (CD-25, UC-62), 87.3% corticosteroid-dependent (CSD), 42.5% refractory/intolerant to immunomodulators. In UC, remission and response were 32.2% and 19.3% after induction, 35.5% and 6.5% at 12 weeks and 29% and 6.5% at 52 weeks. In CD, remission rates were 60%, 52% and 40% respectively. In corticosteroid-dependent and refractory or intolerant to INM patients (UC-41, CD-14), 68.3% of UC achieved remission or response after induction, 51.2% at 12 weeks and 46.3% at 52 weeks, and 62.3%, 64.3% and 42.9% in CD. Maintained remission was achieved by 66.6% in CD and 53.1% in UC. Up to 74.5% of patients required corticosteroids at some timepoint. Corticosteroid-free response/remission was 17.7% in UC and 24% in CD. CONCLUSIONS: GMA is a good therapeutic tool for both in UC and CD patients. In corticosteroid-dependent and refractory or intolerant to INM patients it avoids biological therapy or surgery in up to 40% of them in one year.

Leishmania infection in patients with inflammatory bowel disease: Case series and literature review. / Infección por Leishmania en pacientes con enfermedad inflamatoria intestinal: Serie de casos y revisión de la literatura.

Infection by Leishmania spp. in patients diagnosed with inflammatory bowel disease (IBD) is rare. Considered endemic in the Mediterranean basin, its manifestations are almost exclusive of patients with impaired cellular immunity. Most of the evidence is found through case reports; without guidelines for its management in patients with IBD. In this study we present three cases of Leishmania infection in patients with IBD that lead us to carry out a review of the current literature. Immunosuppressive treatment contributes to this infection, which presents atypically, with a challenging diagnosis. Initial systemic treatment with withdrawal of the immunosuppressant drug seems to be the best therapeutic strategy. Studies are needed in endemic areas to determine its incidence in IBD patients, as well as its possible association with immunosuppressive therapy. The need for serological screening prior introduction of immunosuppressive drugs could be suggested.

Combination of granulocyte-monocyte apheresis and tofacitinib: Multicentre and retrospective study.

OBJECTIVE: Granulocyte-monocyte apheresis (GMA) has shown to be safe and effective in treating ulcerative colitis (UC), also in combination with biologics. The objective of this study is to evaluate the efficacy and safety of combining GMA after primary non-response (PNR) or loss of response (LOR) to tofacitinib (TOFA) in patients with UC. PATIENTS AND METHODS: Retrospective study including all patients with refractory UC who received GMA plus TOFA. Efficacy was assessed 1 and 6 months after finishing GMA by partial Mayo score, C-reactive protein (CRP) and fecal calprotectin (FC). Descriptive statistics and non-parametric tests were used in the statistical analysis. RESULTS: Twelve patients were included (median 46 years [IQR, 37-58]; 67% female; 67% E3). Patients were mostly receiving TOFA 10mg bid (75%), and 33% also concomitant steroids at baseline. Median partial Mayo score at baseline was 7 (IQR, 5-7), and it decreased to a median of 2 (IQR, 0-3) and 0 (IQR, 0-3) after 1 and 6 months (p=0.027 and 0.020, respectively), while no differences were found in CRP and FC. Clinical remission was achieved by 6 patients both at 1 (50%) and 6 months (67%). CF values<250mg/kg were achieved by 2 and 4 patients at 1 and 6 months (data available in 5 and 7 patients, respectively). No patient required dose-escalation of TOFA, and one patient was able to de-escalate the drug. No patient required colectomy and all patients under steroids were able to stop them. CONCLUSION: The combination of GMA and TOFA can be effective in selected cases of UC after PNR or LOR to this drug.

Combination of granulocyte-monocyte apheresis and ustekinumab: Multicentre and retrospective study.

OBJECTIVE: Granulocyte-monocyte apheresis (GMA) has shown to be safe and effective in ulcerative colitis (UC), also in combination with biologics, mainly with anti-TNF. The aim of this study was to evaluate the efficacy and safety of combining GMA after primary non-response (PNR) or loss of response (LOR) to ustekinumab (UST) in patients with UC. PATIENTS AND METHODS: A retrospective study was performed in 12 IBD Units, including all patients with refractory UC or unclassified IBD (IBD-U) who received combined GMA plus UST. The number and frequency of GMA sessions, filtered blood volume and time of each session were registered. Efficacy was assessed 1 and 6 months after finishing GMA by partial Mayo score, C-reactive protein (CRP) and fecal calprotectin (FC). Descriptive statistics and non-parametric tests were used in the statistical analysis. RESULTS: Seventeen patients were included (15 UC, 2 IBD-U; median age 47 years [IQR, 35-61]; 59% male; 53% E3). Most patients (89%) had prior exposure to anti-TNF agents and 53% to vedolizumab; 65% were also receiving steroids at baseline. Median partial Mayo score at baseline was 6 (IQR, 5-7) and it significantly decreased after 1 and 6 months (p=0.042 and 0.007, respectively). Baseline FC significantly decreased after 6 months (p=0.028) while no differences were found in CRP. During follow-up, 18% patients started a new biologic therapy and 12% required surgery; 64% of patients under steroids were able to discontinue them. Adverse events were reported in one patient. CONCLUSION: GMA can recapture the response to UST in selected cases of UC after PNR or LOR to this drug.

Headache in patients with inflammatory bowel disease: Migraine prevalence according to the Migraine Screening-Questionnaire (MS-Q) and headache characteristics.

BACKGROUND: The gut-brain axis describes a complex bidirectional association between neurological and gastrointestinal (GI) disorders. In patients with migraine, GI comorbidities are common. We aimed to evaluate the presence of migraine among patients with inflammatory bowel disease (IBD) according to Migraine Screen-Questionnaire (MS-Q) and describe the headache characteristics compared to a control group. Additionally, we explored the relationship between migraine and IBD severities. METHODS: We performed a cross-sectional study through an online survey including patients from the IBD Unit at our tertiary hospital. Clinical and demographic variables were collected. MS-Q was used for migraine evaluation. Headache disability scale HIT-6, anxiety-depression scale HADS, sleep scale ISI, and activity scale Harvey-Bradshaw and Partial Mayo scores were also included. RESULTS: We evaluated 66 IBD patients and 47 controls. Among IBD patients, 28/66 (42%) were women, mean age 42 years and 23/66 (34.84%) had ulcerative colitis. MS-Q was positive in 13/49 (26.5%) of IBD patients and 4/31 (12.91%) controls (p=0.172). Among IBD patients, headache was unilateral in 5/13 (38%) and throbbing in 10/13 (77%). Migraine was associated with female sex (p=0.006), lower height (p=0.003) and weight (p=0.002), anti-TNF treatment (p=0.035). We did not find any association between HIT-6 and IBD activity scales scores. CONCLUSIONS: Migraine presence according to MS-Q could be higher in patients with IBD than controls. We recommend migraine screening in these patients, especially in female patients with lower height and weight and anti-TNF treatment.

Artificial intelligence for dysplasia detection during surveillance colonoscopy in patients with ulcerative colitis: A cross-sectional, non-inferiority, diagnostic test comparison study.

BACKGROUND AND STUDY AIM: High-definition virtual chromoendoscopy, along with targeted biopsies, is recommended for dysplasia surveillance in ulcerative colitis patients at risk for colorectal cancer. Computer-aided detection (CADe) systems aim to improve colonic adenoma detection, however their efficacy in detecting polyps and adenomas in this context remains unclear. This study evaluates the CADe Discovery™ system's effectiveness in detecting colonic dysplasia in ulcerative colitis patients at risk for colorectal cancer. PATIENTS AND METHODS: A prospective cross-sectional, non-inferiority, diagnostic test comparison study was conducted on ulcerative colitis patients undergoing colorectal cancer surveillance colonoscopy between January 2021 and April 2021. Patients underwent virtual chromoendoscopy (VCE) with iSCAN 1 and 3 with optical enhancement. One endoscopist, blinded to CADe Discovery™ system results, examined colon sections, while a second endoscopist concurrently reviewed CADe images. Suspicious areas detected by both techniques underwent resection. Proportions of dysplastic lesions and patients with dysplasia detected by VCE or CADe were calculated. RESULTS: Fifty-two patients were included, and 48 lesions analyzed. VCE and CADe each detected 9 cases of dysplasia (21.4% and 20.0%, respectively; p=0.629) in 8 patients and 7 patients (15.4% vs. 13.5%, respectively; p=0.713). Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy for dysplasia detection using VCE or CADe were 90% and 90%, 13% and 5%, 21% and 2%, 83% and 67%, and 29.2% and 22.9%, respectively. CONCLUSIONS: The CADe Discovery™ system shows similar diagnostic performance to VCE with iSCAN in detecting colonic dysplasia in ulcerative colitis patients at risk for colorectal cancer.

Suboptimal response to tumor necrosis factor antagonists in inflammatory bowel disease in Latin America: EXPLORE LATAM study.

OBJECTIVE: Data on anti-tumor necrosis factor (anti-TNF) treatment and suboptimal response (SOR) among patients with inflammatory bowel diseases (IBD) in Latin America (LATAM) are scarce. This study evaluated the incidence and indicators of SOR to anti-TNF therapy in patients with ulcerative colitis (UC) and Crohn's disease (CD) from Argentina, Colombia and Mexico. PATIENTS AND METHODS: We performed retrospective analysis of data from LATAM patients of the EXPLORE study (NCT03090139) including adult patients with IBD who initiated anti-TNF therapy between March 2010 to March 2015. The cumulative incidence of SOR to first-line anti-TNF therapy was assessed. A physician survey to assess barriers to anti-TNF therapies was also carried out. RESULTS: We included 185 IBD patients (UC/CD: 99/86) treated with first-line anti-TNF from Argentina (38 UC; 40 CD), Colombia (21 UC; 25 CD) and Mexico (40 UC; 21 CD). 36.4% of patients with UC and 46.5% of patients with CD experienced SOR to anti-TNF therapy during the median (interquartile range) observational period: 49.0 months (37.2-60.1) in UC, and 50.0 months (40.9-60.1) in CD. The most common indicator of SOR among patients was augmentation of non-biologic therapy (UC: 41.7%; CD: 35.0%). Affordability and late referral to IBD specialist care centers were the most common barriers to anti-TNF therapies. CONCLUSIONS: SOR to anti-TNF therapy was common in LATAM IBD patients, where augmentation with non-biologic therapy represented the most frequent indicator of SOR across indications. Our findings contribute to the current evidence on the unmet needs associated with anti-TNF in LATAM.

Recommendations on the management of severe obesity in patients with inflammatory bowel disease of the Spanish Group on Crohn's Disease and Ulcerative Colitis (GETECCU), Spanish Society of Obesity (SEEDO), Spanish Association of Surgery (AEC) and Spanish Society of Digestive Endoscopy (SEED). / Recomendaciones sobre el manejo de la obesidad grave en pacientes con enfermedad inflamatoria intestinal del Grupo Español de Trabajo en Enfermedad Inflamatoria Intestinal (GETECCU), Sociedad Española de Obesidad (SEEDO), Asociación Española de Cirugía (AEC) y Sociedad Española de Endoscopia Digestiva (SEED).

Obesity is a multifactorial, chronic, progressive and recurrent disease considered a public health issue worldwide and an important determinant of disability and death. In Spain, its current prevalence in the adult population is about 24% and an estimated prevalence in 2035 of 37%. Obesity increases the probability of several diseases linked to higher mortality such as diabetes, cardiovascular disease, hyperlipidemia, arterial hypertension, non-alcoholic fatty liver disease, several types of cancer, or obstructive sleep apnea. On the other hand, although the incidence of inflammatory bowel disease (IBD) is stabilizing in Western countries, its prevalence already exceeds 0.3%. Paralleling to general population, the current prevalence of obesity in adult patients with IBD is estimated at 15-40%. Obesity in patients with IBD could entail, in addition to its already known impact on disability and mortality, a worse evolution of the IBD itself and a worse response to treatments. The aim of this document, performed in collaboration by four scientific societies involved in the clinical care of severe obesity and IBD, is to establish clear and concise recommendations on the therapeutic possibilities of severe or typeIII obesity in patients with IBD. The document establishes general recommendations on dietary, pharmacological, endoscopic, and surgical treatment of severe obesity in patients with IBD, as well as pre- and post-treatment evaluation.

Therapeutic drug monitoring in inflammatory bowel diseases. Position statement of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis. / Monitorización terapéutica de los fármacos biológicos en la enfermedad inflamatoria intestinal. Documento de Posicionamiento del Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa (GETECCU).

The treatment of inflammatory bowel disease has undergone a significant transformation following the introduction of biologic drugs. Thanks to these drugs, treatment goals have evolved from clinical response and remission to more ambitious objectives, such as endoscopic or radiologic remission. However, even though biologics are highly effective, a significant percentage of patients will not achieve an initial response or may lose it over time. We know that there is a direct relationship between the trough concentrations of the biologic and its therapeutic efficacy, with more demanding therapeutic goals requiring higher drug levels, and inadequate exposure being common. Therapeutic drug monitoring of biologic medications, along with pharmacokinetic models, provides us with the possibility of offering a personalized approach to treatment for patients with IBD. Over the past few years, relevant information has accumulated regarding its utility during or after induction, as well as in the maintenance of biologic treatment, in reactive or proactive strategies, and prior to withdrawal or treatment de-escalation. The aim of this document is to establish recommendations regarding the utility of therapeutic drug monitoring of biologics in patients with inflammatory bowel disease, in different clinical practice scenarios, and to identify areas where its utility is evident, promising, or controversial.

Optimizing treatment of mild to moderate ulcerative colitis: CU-forum Delphi consensus. / Optimización del tratamiento de la colitis ulcerosa leve a moderada: Consenso Delphi CU-Forum.

BACKGROUND AND OBJECTIVE: Ulcerative colitis (UC) clinical guidelines include the best available evidence, although not all clinical situations are answered, so their management can be controversial. The aim of this study is to identify the situations of mild to moderate UC susceptible to controversy and to evaluate the degree of agreement or disagreement with specific proposals. METHODS: Inflammatory bowel disease (IBD) expert discussion meetings were used to identify criteria, attitudes and opinions regarding the management of UC. A Delphi questionnaire was then developed with 60 items regarding antibiotics, salicylates and probiotics; local, systemic and topical corticosteroids; and immunosuppressants. RESULTS: Consensus was reached in 44 statements (73.3%); 32 in agreement (53.3%) and 12 in disagreement (20.0%). Some of them were: it is not necessary the systematic use of antibiotics despite the severity of the outbreak, being reserved when there is suspicion of infection or systemic toxicity; when faced with a mild-moderate outbreak of UC and in patients who do not respond to aminosalicylates, it is appropriate to use a dose of beclomethasone of 10mg/day for one month and 5mg/day for another month; it is advised that the dose of azathioprine be administered in a single dose. CONCLUSIONS: IBD experts agree on most of the proposals identified for managing mild to moderate UC and there is a need for scientific evidence in some specific situations where expert opinion may be helpful.

Mesalazine dose modification based on faecal calprotectin levels in patients with ulcerative colitis in clinical remission. / Modificación de la dosis de mesalazina en función de los niveles de calprotectina fecal en pacientes con colitis ulcerosa en remisión clínica.

BACKGROUND: Faecal calprotectin (FC) shows an excellent correlation with endoscopic and histological activity of ulcerative colitis (UC) and it is the best predictor of clinical relapse. Our aim was to evaluate the usefulness of modifying the dose of mesalazine based on FC levels, in clinical practice. METHODS: Retrospective, single-centre study in UC patients in clinical remission while treated with mesalazine which dosage was decreased (DOWN) or increased (UP) according to FC levels. The main endpoint was the long-term maintenance of clinical remission. RESULTS: A total of 56 patients were included (39 DOWN, 17 UP). In the DOWN group, the median baseline dose of mesalazine was 3.6g/day and the median baseline FC was 36µg/g. After a median follow-up of 22 months, 28% required rescue therapy. The cumulative relapse-free survival after tapering was 91% and 82% at 12 and 24 months, respectively. In the UP group, the median baseline dose of mesalazine was 2.4g/day, with a median baseline FC of 524µg/g. After a median follow-up of 12 months, 29% required rescue therapy. The cumulative relapse-free survival after dose increase was 86% and 72% at 12 and 24 months, respectively. CONCLUSIONS: Mesalazine dose modification based on FC monitoring seems to be a safe strategy in patients with UC in clinical remission, with a probability of clinical relapse around 20% at two years.

High incidence of surgery and initiation of medical therapies after colectomy for ulcerative colitis or inflammatory bowel disease unclassified.

BACKGROUND AND AIMS: Despite novel medical therapies, colectomy has a role in the management of patients with ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU). This study aimed to determine the incidence of unplanned surgery and initiation of immunomodulatory or biologic therapy (IMBT) after colectomy in patients with UC or IBDU, and identify associated factors. METHODS: Data of patients with preoperative diagnosis of UC or IBDU who underwent colectomy and were followed up at a single tertiary centre was retrospectively collected. The primary outcome was the risk of unplanned surgery and initiation of IMBT during follow-up after colectomy. Secondary outcomes were development of Crohn's disease-like (CDL) complications and failure of reconstructive techniques. RESULTS: 68 patients were included. After a median follow-up of 9.9 years, 32.4% of patients underwent unplanned surgery and IMBT was started in 38.2%. Unplanned surgery-free survival was 85% (95% confidence interval [CI] 73.8-91.6%) at 1 year, 76% (95% CI 63.2-84.9%) at 5 years and 69.1% (95% CI 55-79.6%) at 10 years. IMBT-free survival was 96.9% (95% CI 88.2-99.2%) at 1 year, 77.6% (95% CI 64.5-86.3%) at 5 years and 63.3% (95% CI 48.8-74.7%) at 10 years. 29.4% of patients met criteria for CDL complications. CDL complications were significantly associated to IMBT (hazard ratio 4.5, 95% CI 2-10.1). CONCLUSION: In a retrospective study, we found a high incidence of unplanned surgery and IMBT therapy initiation after colectomy among patients with UC or IBDU. These results further question the historical concept of surgery as a "definitive" treatment.

Ileal reservoir-associated complications in ulcerative colitis versus familial adenomatous polyposis: Impact on patient quality of life. / Complicaciones asociadas al reservorio ileal en colitis ulcerativa versus poliposis familiar adenomatosa: Impacto en la calidad de vida del paciente.

BACKGROUND: Proctocolectomy with ileal reservoir is the surgical procedure of choice for patients with ulcerative colitis and familial adenomatous polyposis. OBJECTIVES: To evaluate long-term postoperative complications (1994-2019) in patients operated for familial adenomatous polyposis (FAP) and ulcerative colitis (UC) and the degree of satisfaction with the procedure. METHODS: Observational study based on the analysis of a retrospective database with prospective follow-up in 115 consecutive patients: 79 with UC and 36 with FAP. A total of 88 patients were followed up, 60 with UC and 28 with PFA. RESULTS: 48 males (54.4%) with a mean age of 44.8 ± 10.6 years were evaluated. Indications for surgery were intractable disease in 54 patients (47%), dysplasia/cancer in 43 (37%), severe bleeding in 4 (4%) and perforation in 3 (3%). A proctectomy and mucosectomy of the rectal stump was performed in 67 (76.1%), and a double stapling technique in 21. A protective ileostomy was performed in all patients with UC and FAP. No differences were found in early complications between the two groups. Late complications showed a higher rate of reservoritis in UC patients compared to FAP (44.9 vs. 14.3%, p = 0.001), with more refractory reservoritis in the UC group (13.3 vs. 0%, p = 0.04) with no differences in bowel obstruction, strictures, or anastomotic fistulas. Overall satisfaction and adaptation were considered good in 87% of UC patients and only 57% in the FAP group (p < 0.01). CONCLUSIONS: Proctocolectomy with ileal reservoir has comparable morbidity and mortality, except for the higher rate of reservoritis in patients with a history of UC, despite this contingency there is a better quality of life and greater acceptance of surgery in UC patients than in FAP patients.

Incidence, and natural history of inflammatory bowel disease in Castilla y León: Prospective and multicenter epidemiological study. / Incidencia e historia natural de la enfermedad inflamatoria intestinal en Castilla y León: estudio prospectivo, multicéntrico y poblacional.

INTRODUCTION: The incidence of inflammatory bowel disease (IBD) is increasing worldwide. OBJECTIVES: To evaluate the incidence of IBD in Castilla y León describing clinical characteristics of the patients at diagnosis, the type of treatment received and their clinical course during the first year. MATERIALS AND METHODS: Prospective, multicenter and population-based incidence cohort study. Patients aged >18 years diagnosed during 2017 with IBD (Crohn's disease [CD], ulcerative colitis [UC] and indeterminate colitis [IC]) were included from 8 hospitals in Castilla y León. Epidemiological, clinical, and therapeutic variables were registered. The global incidence and disease incidence were calculated. RESULTS: 290 patients were diagnosed with IBD (54.5% UC, 45.2% CD, and 0.3% IC), with a median follow-up of 9 months (range 8-11). The incidence rate of IBD in Castilla y Leon in 2017 was 16.6 cases per 10,000 inhabitants-year (9/105 UC cases and 7.5/105 CD cases), with a UC/CD ratio of 1.2:1. Use of systemic corticosteroids (47% vs 30%; P=.002), immunomodulatory therapy (81% vs 19%; P=.000), biological therapy (29% vs 8%; P=.000), and surgery (11% vs 2%; p=.000) were significatively higher among patients with CD comparing with those with UC. CONCLUSIONS: The incidence of patients with UC in our population increases while the incidence of patients with CD remains stable. Patients with CD present a worse natural history of the disease (use of corticosteroids, immunomodulatory therapy, biological therapy and surgery) compared to patients with UC in the first year of follow-up.

GADECCU 2022 Guideline for the treatment of Ulcerative Colitis. Adaptation and updating of the GETECCU 2020 Guideline. / Guía GADECCU 2022 para el tratamiento de la colitis ulcerosa. Adaptación y actualización de la Guía GETECCU 2020.

INTRODUCTION: Ulcerative colitis (UC) is a chronic inflammatory disease that compromises the colon, affecting the quality of life of individuals of any age. In practice, there is a wide spectrum of clinical situations. The advances made in the physio pathogenesis of UC have allowed the development of new, more effective and safer therapeutic agents. OBJECTIVES: To update and expand the evaluation of the efficacy and safety of relevant treatments for remission induction and maintenance after a mild, moderate or severe flare of UC. RECIPIENTS: Gastroenterologists, coloproctologists, general practitioners, family physicians and others health professionals, interested in the treatment of UC. METHODOLOGY: GADECCU authorities obtained authorization from GETECCU to adapt and update the GETECCU 2020 Guide for the treatment of UC. Prepared with GRADE methodology. A team was formed that included authors, a panel of experts, a nurse and a patient, methodological experts, and external reviewers. GRADE methodology was used with the new information. RESULTS: A 118-page document was prepared with the 44 GADECCU 2022 recommendations, for different clinical situations and therapeutic options, according to levels of evidence. A section was added with the new molecules that are about to be available. CONCLUSIONS: This guideline has been made in order to facilitate decision-making regarding the treatment of UC, adapting and updating the guide prepared by GETECCU in the year 2020.

De-escalating therapy in inflammatory bowel disease: Results from an observational study in clinical practice.

BACKGROUND AND OBJECTIVES: Combination therapy with an immunomodulator (IMM) and an anti-TNF is commonly recommended in Crohn's disease (CD) and ulcerative colitis (UC) patients. However, little is known about relapse rates after therapeutic de-escalation. This study aimed to evaluate the risk of relapse in a cohort of UC and CD patients with long-standing clinical remission after discontinuation of IMM or anti-TNF and to identify predictive factors for relapse. METHODS: This retrospective study included patients with UC or CD on combination therapy and clinical remission for at least 6 months. IMM or anti-TNF was stopped upon physician decision. Primary objective was to evaluate the relapse rates after discontinuation of IMM or anti-TNF and to analyze predictors of relapse. RESULTS: The study included 88 patients, 48 patients (54.5%) discontinued IMM and 40 (45.5%) anti-TNF. During follow-up, relapse rates were 16.7% and 52.5% in the IMM discontinuation group and anti-TNF discontinuation group, respectively (p<0.001). Multivariate analysis showed that anti-TNF discontinuation (HR=3.01; 95% CI=1.22-7.43) and ileal CD location (HR=2.36; 95% CI=1.02-5.47) were predictive factors for relapse while inflammatory CD phenotype was a protective factor (HR=0.32; 95% CI=0.11-0.90). Reintroduction of anti-TNF upon relapse was effective and safe. CONCLUSION: Anti-TNF discontinuation led to significantly higher relapse rates compared to IMM discontinuation in UC and CD patients on combination therapy. Anti-TNF discontinuation and ileal CD location were identified as predictive factors for relapse while inflammatory CD phenotype was a protective factor. Retreatment after anti-TNF discontinuation was effective and safe.

Clinical and therapeutic characterisation of a multicentre cohort of patients with inflammatory bowel disease in Colombia. / Caracterización clínica y terapéutica de una cohorte multicéntrica de pacientes con enfermedad inflamatoria intestinal en Colombia.

INTRODUCTION: In Latin America and Colombia there are few studies about the clinical and therapeutic characteristics of patients with inflammatory bowel disease (IBD). The objective of this study is to obtain an approximation to these data from a sample of patients from different reference centres in Colombia. PATIENTS AND METHODS: Cross-sectional study in adult and paediatric patients, with IBD, attended ambulatory in 6 institutions in different cities, between 2017 and 2020 information was collected on different dates, about demographic, clinical, and therapeutic aspects. RESULTS: Six hundred and five subjects, 565 (93.4%) adults, mean age 43 years (SD 12.78), 64% with ulcerative colitis (UC). The age at diagnosis of UC was 41.9 years, while in Crohn's disease (CD) it was 47.9 years. In UC, there was greater left involvement (47.2%), and in CD, 42.8% ileocolonic (L3). More than 50% were in mild activity or clinical remission. In UC, the biologic requirement was 27.2%, while in CD, 78%. Overall hospitalisation requirement was 39.5%, and the need for surgery was 37.5% in UC and 62.5% in CD. Also, 40 pediatric patients, 90% female, with UC being more frequent (80%). In UC, 83.3% presented extensive colitis, and in CD, all with ileocolonic localization (L3). More than 95% were in mild activity or remission. Biologic therapy was required in 16.6% and 75% for UC and CD, respectively. The frequency of hospitalisations and surgery was 2.7%. CONCLUSIONS: This study shows some unique characteristics of patients with IBD in Colombia. An earlier diagnosis is required, with a better therapeutic approach.

Perception of the need for dietary advice and dietary modifications in inflammatory bowel disease patients. / Percepción de la necesidad de asesoramiento dietético y modificaciones alimentarias en pacientes con enfermedad inflamatoria intestinal.

BACKGROUND AND AIM: In inflammatory bowel disease (IBD), diet can be perceived as a trigger for relapses or clinical worsening, dietary modifications are frequent and not derived from professional advice. The aim of this study was to evaluate the perception of the need for dietary advice in patients with IBD, to know the dietary modifications adopted and, it's effect on IBD. METHODS: An anonymous structured questionnaire with a visual analog scale (0-10) was distributed to consecutive outpatients from our IBD unit. RESULTS: A total of 124 complete the questionnaire (54% ulcerative colitis, 46% Crohn's disease). Mean age was 47±12 years. Dietary advice provided in the clinic was assessed with a median score of 7 (IIC, 4.50-9.00). 40% sought external dietary advice, often during the first year after diagnosis (70%). The most frequent dietary recommendations from an external professional were: dairy free diet (29%), low fat (27%), gluten free (23%), and low fiber (21%). Dietary advice from external source was assessed with a median score of 7.50 (IIC, 5.50-9.50), improving digestive symptoms in 73% of cases. Regarding dietary modifications, 61% excluded some foods (57% permanently) and 11% fasted on their own decision. CONCLUSIONS: IBD patient show a clear need for dietary advice, especially at the time of IBD diagnosis. Early specific and in-depth dietary information would increase patient satisfaction and could prevent the adoption of unjustified exclusion diets.
