RESUMEN
BACKGROUND: Previous data support that the inflammatory process underlying ulcerative colitis (UC) and Crohn's disease (CD) can start years before the diagnosis. The aim of this study was to determine if patients with an incidental diagnosis of UC or CD demonstrate an increase in healthcare utilization in the years preceding the symptomatic onset of the disease. METHODS: We performed a multicenter, retrospective, hospital-based, case-control study. Patients with an incidental diagnosis of UC or CD during the colorectal cancer screening program at 9 hospitals were included. Cases were matched 1:3 and compared separately with two control populations: one including healthy non-IBD subjects adjusted by gender, age, and date, excluding those with visits to Gastroenterology; and a second control cohort of UC/CD patients with symptomatic onset. RESULTS: A total of 124 patients with preclinical inflammatory bowel disease (IBD) were included (87 UC, 30 CD, 7 IBD unclassified; median age 56 years). Patients with preclinical IBD showed an increase in the number of visits to Primary Care up to 3 and 5 years before diagnosis (aIRR 1.59, 95% CI [1.37-1.86], p = 0.001; aIRR 1.43, 95% CI [1.24-1.67], p = 0.01) and more frequent use of steroids (aOR 2.84, 95% CI [1.21-6.69], p = 0.03; aOR 2.25, 95% CI [1.06-4.79], p = 0.04) compared to matched non-IBD healthy controls, respectively. In contrast, patients with a symptomatic onset visited Primary Care less frequently, but they had an increase in the number of visits to Emergency Department, specialist care, sick-leaves, CT/ultrasound examinations, and use of antibiotics or systemic steroids. CONCLUSIONS: There is an increased need for medical assistance and use of systemic steroids during the presymptomatic phase of IBD. These results will help in establishing new tools for early identification of IBD in the future.

Toxic megacolon is most commonly considered as a complication of inflammatory bowel disease, especially ulcerative colitis and colonic Crohn's disease to a lesser extent. It appears in the context of moderate-to-severe disease and often requires colectomy. Currently, after an inadequate response to conventional therapy with systemic corticosteroids, the use of cyclosporine or infliximab is considered as an alternative option, prior to surgical intervention. We present a case report of toxic megacolon in a patient with a severe refractory colonic Crohn's disease, where anti-tumor necrosis factor (anti-TNF) therapies were contraindicated. Consequently, we decided to use ustekinumab as a rescue therapy, despite insufficient evidence to provide recommendations for this indication.

BACKGROUND: The immune response involved in the pathogenesis of Inflammatory Bowel Disease (IBD) may be present years before the diagnosis, but the characteristics of the disease during the preclinical period have been scarcely investigated. AIM: To describe the microscopic findings of preclinical IBD and its relationship with the natural history of the disease. METHODS: Medical records from all patients with an incidental diagnosis of IBD during a screening colonoscopy were included in this multicentric and retrospective study. We assessed 15 histologic items in the biopsy samples at diagnosis, and the Geboes score was calculated in patients with Ulcerative Colitis (UC). The main outcome was the development of gastrointestinal symptoms during follow-up. RESULTS: We included 110 patients (79 UC, 24 Crohn's Disease (CD) and 7 with unclassified disease). In UC the most common histologic findings were acute or chronic inflammatory infiltrate and crypt epithelial polymorphs, while in CD we observed acute or chronic neutrophilic infiltrate and epithelial irregularity. Granuloma were only observed in 4% of CD patients. Crypt distortion and the infiltration of neutrophils in the epithelium were associated with a higher risk of developing symptomatic disease. CONCLUSIONS: Preclinical IBD shows specific microscopic findings and they are associated with the progression to symptomatic disease.

BACKGROUND: Adalimumab is the second tumour necrosis factor antagonist (anti-TNF) adopted for the treatment of ulcerative colitis. Clinical data from naïve patients are scarce. AIM: Examine the response to adalimumab in TNF-antagonist-naïve patients. METHODS: This multicentre, observational, prospective study was conducted using a cohort of consecutive patients with ulcerative colitis. Clinical remission, mucosal healing and deep remission were examined employing the Mayo Score and Mayo Endoscopic Score. Clinical response was assessed using the Partial Mayo Score. RESULTS: Of 53 individuals included in this study, 49.1% of patients were in clinical remission at week 8 and 60.3%, at week 52. Clinical response was observed in 84.9% and 69.8%, respectively. Mucosal healing was found in 62.3% and 67.9% of the patients, and 43.4% and 58.4% showed deep remission at week 8 and 52, respectively. After a year, 71.7% of the patients continued the adalimumab treatment. Adverse effects were observed in 28.3% of patients. Multivariate analysis showed that the long-term factor predictive of response at week 52 was the response in week 8 (expressed as Mayo Score; OR 0.66; 95% IC 0.1-0.67, pâ¯<â¯0.006). CONCLUSIONS: Adalimumab treatment of ulcerative colitis is effective; the results are better in clinical practice and in patients naïve to anti-TNF.

BACKGROUND & AIMS: Inflammatory bowel disease (IBD) is a chronic disease usually diagnosed after the appearance of gastrointestinal symptoms. Little is known about IBD progression during its early and even preclinical phases. We aimed to determine the number of new incidental diagnoses of IBD in an older population, and evaluate disease progression from its early stages. METHODS: We performed a retrospective analysis of 31,005 colonoscopies performed during colorectal cancer screening of patients with positive results from fecal immunochemical tests, at 11 centers in the Basque Country (Spain) from 2009 through 2014. We collected clinical and laboratory data from all asymptomatic individuals suspected to have IBD during screening colonoscopies, with histologic confirmation. RESULTS: Colonoscopy screening led to 79 new diagnoses of ulcerative colitis, 24 of Crohn's disease, and 7 of unclassified colitis (average patient age, 57 y; interquartile range, 52-62 y; 57% male). Eleven patients had symptoms before colonoscopy and were excluded from the analysis. Among those patients who were asymptomatic at diagnosis, 36% developed symptoms after a follow-up period of 25 months (interquartile range, 10.5-42 mo), mostly rectal bleeding and diarrhea. Treatment was prescribed for 81 patients (88%), and 2 cases required surgery. CONCLUSIONS: We analyzed data from a large cohort of patients with IBD diagnosed at early or even preclinical stages, from an older population. New incidental diagnoses of IBD were made in 0.35% of individuals undergoing a population-based screening colonoscopy-most were classified as ulcerative colitis. Approximately one third of patients developed symptoms during the follow-up period.
