Characterization and prevalence of extraintestinal manifestations in a cohort of patients with inflammatory intestinal disease in Medellin, Colombia. / Caracterización y prevalencia de manifestaciones extraintestinales en una cohorte de pacientes con enfermedad inflamatoria intestinal en Medellín (Colombia).

INTRODUCTION: Extraintestinal manifestations (EIMs) are frequent in patients with inflammatory bowel disease (IBD). Our objective is to characterize and determine the prevalence of MEIs in our cohort of patients with IBD. PATIENTS AND METHODS: A retrospective study was carried out in adult patients with IBD at the Pablo Tobón Uribe Hospital in Medellín. Colombia. Articular MEIs, primary sclerosing cholangitis (PSC), both ophthalmological and dermatological, were considered. Absolute and relative frequencies were used. The Chi square test of independence was used to compare 2proportions and the odds ratio (OR) was estimated. RESULTS: Our registry has 759 patients with IBD, 544 present UC (71.6%), 200 CD (26.3%) and 15 unclassifiable IBD (1.9%); 177 patients with IBD (23.3%) presented EIMs, 123 of 544 (22.6%) with UC and 53 of 200 (26.5%) with CD (OR: 0.81, 95% CI: 0.55-1.17, P=0.31). Regarding the type of EIMs, the articular ones were the most frequent (13.5%), more in CD than in UC (20.0 vs. 11.3%, OR 1.94, 95% CI: 1.25-3.00, P=0.0037). Patients with IBD and EIMs used more antibodies against tumor necrosis factor (anti-TNFs), compared to those without EIMs (43.5 vs. 18.5%, OR 3.38, 95% CI: 2.31-4.90, P=0.0001). CONCLUSIONS: The prevalence of EIMs in our cohort is high (23.3%) and the most frequent type is joint. Anti-TNFs are most used when IBD and EIMs coexist. Our study provides valuable information on the association of EIMs and IBD in Latin America.

Clinical utility of the small bowel capsule endoscopy in the study of small bowel diseases in Colombia: Results of a national registry. / Utilidad clínica de la videocápsula endoscópica en el estudio de patologías de intestino delgado en Colombia: resultados de un registro nacional.

INTRODUCTION: The small bowel capsule endoscopy (SBCE) has revolutionised the study of small bowel diseases. The objective of this study is to determine the indications, findings and diagnostic yield of SBCE in a national registry. PATIENTS AND METHODS: An observational, analytical cross-sectional study was carried out, analysing the SBCE records at seven centres in the country, where different variables were collected. RESULTS: 1,883 SBCEs were evaluated. The average age was 55.4 years (5.6-94.2). The most frequent indications were suspicion of small bowel bleeding (SBB) (64.4%), study of Crohn's disease (15.2%) and chronic diarrhoea (11.2%). 54.3% were prepared with laxatives. The most frequent lesions found were erosions/ulcers (31.6%), angioectasias (25.7%) and parasitosis (2.7%). The diagnostic yield (P1+P2, Saurin classification) of SBCE in SBB was 60.6%, being higher in overt SBB (66.0%) compared to occult SBB (56.0%) (P=.003). The studies with better preparation showed higher detection of lesions (93.8% vs. 89.4%) (OR=1.8, CI: 95%: 1.2-2.6; P=.004). The SBCE complication rate was 3.1%, with complete SB visualisation at 96.6% and SB retention rate of 0.7%. 81.5% of SBCEs were performed on an outpatient basis, and presented a greater complete SB visualisation than hospital ones (97.1% vs. 94.3%) (OR=2.1, CI: 95%, 1.2-3.5; P=.008). CONCLUSIONS: The indications, findings and diagnostic performance of SBCEs in Colombia are similar to those reported in the literature, with a high percentage of complete studies and a low rate of complications.

Trends in the epidemiology of inflammatory bowel disease in Colombia by demographics and region using a nationally representative claims database and characterization of inflammatory bowel disease phenotype in a case series of Colombian patients.

ABSTRACT: The incidence of inflammatory bowel disease (IBD) is on the rise in Latin America. The aims of this study were to examine epidemiologic trends of IBD in Colombia by demographics, region, urbanicity, and to describe the IBD phenotype in a large well-characterized Colombian cohort.We used a national database of 33 million adults encompassing 97.6% of the Colombian population in order to obtain epidemiologic trends of IBD using International Classification of Diseases 10codes for adults with ulcerative colitis (UC) and Crohn disease (CD). We calculated the incidence and prevalence of UC and CD from 2010-2017 and examined epidemiologic trends by urbanicity, demographics, and region. We then examined the IBD phenotype (using Montreal Classification), prevalence of IBD-related surgeries, and types of IBD-medications prescribed to adult patients attending a regional IBD clinic in Medellin, Colombia between 2001 and 2017.The incidence of UC increased from 5.59/100,000 in 2010 to 6.3/100,000 in 2017 (relative risk [RR] 1.12, confidence interval (CI) (1.09-1.18), P < .0001). While CD incidence did not increase, the prevalence increased within this period. The Andes region had the highest incidence of IBD (5.56/100,000 in 2017). IBD was seen less in rural regions in Colombia (RR=.95, CI (0.92-0.97), p < .01). An increased risk of IBD was present in women, even after adjusting for age and diagnosis year (RR 1.06 (1.02-1.08), P = .0003). The highest IBD risk occurred in patients 40 to 59 years of age. In the clinic cohort, there were 649 IBD patients: 73.7% UC and 24.5% CD. Mean age of diagnosis in CD was 41.0 years and 39.9 years in UC. UC patients developed mostly pancolitis (43%). CD patients developed mostly ileocolonic disease and greater than a third of patients had an inflammatory, non-fistulizing phenotype (37.7%). A total of 16.7% of CD patients had perianal disease. CD patients received more biologics than UC patients (odds ratio: 3.20, 95% CI 2.19-4.69 P < .001).Using both a national representative sample and a regional clinic cohort, we find that UC is more common in Colombia and is on the rise in urban regions; especially occurring in an older age cohort when compared to Western countries. Future studies are warranted to understand evolving environmental factors explaining this rise.

Resumen Introducción: la anemia es la complicación más frecuente en enfermedad inflamatoria intestinal (EII). El objetivo de este estudio fue determinar la prevalencia, asociaciones y tratamiento de la anemia en EII en nuestro medio. Materiales y métodos: se analizaron de forma retrospectiva datos de pacientes adultos con EII del Hospital Pablo Tobón Uribe en Medellín, Colombia, que consultaron desde 2001 hasta febrero de 2019. Se emplearon frecuencias absolutas y relativas. Para comparar dos proporciones se utilizó la prueba de chi cuadrado de independencia y se estimó el Odds ratio (OR). Resultados: se documentaron 759 pacientes con EII, de los cuales 544 (71,6 %) presentaron colitis ulcerativa (CU); 200 (26,3 %), enfermedad de Crohn (EC), y 15, EII no clasificable (1,9 %). En total, 185 (24,4 %) pacientes con EII presentaron anemia, que es menos frecuente en CU que en EC (22,2 % frente a 32,5 %, respectivamente; OR: 0,684; IC: 0,456-0,96; p = 0,03). Los pacientes con CU extensa (54,1 %) tenían más anemia que aquellos con CU no extensa (46,3 %) (OR: 4,4; IC: 2,6-7,4; p = 0,001); lo mismo se observó al comparar la CU grave (66,1 %) con la no grave (32,3 %) (OR: 4,95; IC: 2,87-8,51; p = 0,000). En la EC, los pacientes con comportamiento no inflamatorio (B2, B3: 73,9 %) presentaron más anemia en comparación con aquellos con comportamiento inflamatorio (B1: 26,2 %) (OR: 0,35; IC: 0,18-0,67; p = 0,000). 44,3 % de los pacientes no recibió tratamiento, 19,5 % recibió hierro oral, 20,0 % recibió hierro intravenoso y 16,2 % fue transfundido. Conclusiones: la anemia es una complicación frecuente de la EII en nuestro medio (24,4 %). A pesar de las guías internacionales, el tratamiento es subóptimo en nuestro medio.

Abstract Introduction: Anemia is the most frequent complication of inflammatory bowel disease (IBD). This study aims to determine the prevalence, connection, and treatment of anemia in IBD in a local context. Materials and Methods: This retrospective study was conducted at The Pablo Tobon Uribe Hospital, in Medellín (Colombia) with adult patients who (were admitted) came for consultation from 2001, until February 2019. Absolut and relative frequencies were calculated. The Chi square test of independence was applied for comparing two proportions and the odds ratio (OR) was estimated. Results: A total of 759 IBD patients were enrolled, 544 (71.6%) with ulcerative colitis (UC); 200 (26.3%) Crohn's disease (CD), and 15 (1.9%) with non-classifiable IBD. In total, 185 (24,4 %) IBD patients had a diagnosis of anemia, that is less frequent in UC patients that in CD patients (22,2 % versus 32,5 %, respectively; OR: 0,684; CI: 0,456-0,96; p = 0,03). Extensive UC patients (54,1 %) had a more recurrent level of anemia than non-extensive UC (46,3 %) (OR: 4,4; CI: 2,6-7,4; p = 0,001); the same result was observed when severe UC (66,1 %) was compared with UC non-severe (32,3 %) (OR: 4,95; CI: 2,87-8,51; p = 0,000). In the analysis of CD, patients with a non-inflammatory response (B2, B3: 73,9 %) had a more recurrent level of anemia than patients with an inflammatory response (B1: 26,2 %) (OR: 0,35; CI: 0,18-0,67; p = 0,000). 44,3 % of the total number of patients received treatment, 19,5 % received oral iron, 20,0 % received intravenous iron, and 16,2 % received a blood transfusion. Conclusions: In our context, Anemia is a common complication in IBD cases (24,4 %). Despite the existence of international guidelines, the treatment in our context is not optimal.
