Incidence of inflammatory bowel disease and phenotype at diagnosis in 2011: results of the Epi-IBD 2011 study in the Vigo area.

OBJECTIVE: to validate the incidence of inflammatory bowel disease (IBD) reported in Vigo in 2010 within the Epi-IBD study, which was the highest incidence reported so far in Spain. METHODS: an epidemiological, prospective, population-based inception cohort study. All incident cases of IBD living in the Vigo area at diagnosis from January 1 to December 31, 2011 were included. RESULTS: one hundred patients were diagnosed (62 % men; median age, 43.27 years): 49 with ulcerative colitis (UC), 34 with Crohn's disease (CD), and 17 with IBD unclassified (IBDU). The incidence (per 100,000 inhabitants/year) was 17.56 (CD: 5.97; UC: 8.60; IBDU: 2.98), similar to that reported in 2010. The incidence in the non-pediatric population was 19.66 (CD: 6.89, UC: 9.52; IBDU: 3.04). CD and UC phenotype was similar in 2010 and 2011. CONCLUSION: this study supports the increased incidence of EII in the Vigo area reported in 2010.

Incidence and phenotype at diagnosis of inflammatory bowel disease. Results in Spain of the EpiCom study / Incidencia y fenotipo al diagnóstico en la enfermedad inflamatoria intestinal. Resultados del estudio EpiCom en España

INTRODUCTION: Incidence of inflammatory bowel disease (IBD) is increasing progressively. Few recent epidemiological prospective studies are available in Spain. The Epicom study, a population-based inception cohort of unselected IBD patients developed within the European Crohn's and Colitis Organization, was started in 2010. Vigo is the only Spanish area participating. OBJECTIVE: To describe the incidence of IBD in the Vigo area and the phenotypical characteristics at diagnosis and to compare them with previous data available in Spain. MATERIAL AND METHODS: Epidemiological, descriptive, prospective, and population-based study. All incident cases of IBD during 2010 and living in the Vigo area at diagnosis were included. The Copenhagen Diagnostic criteria were used to define cases. Background population at the start of the study was 579,632 inhabitants. Data were prospectively entered in the EpiCom database. RESULTS: A total of 106 patients were included (57.5% men, median age 39.5 years). Of them 53 were diagnosed of as Crohn's disease (CD), 47 ulcerative colitis (UC) and six IBD unclassified (IBDU). The incidence rate per 100,000 per year for patients aged 15 years or older was 21.4 (10.8 for CD, 9.4 for UC, 1.2 IBDU). Including pediatric population incidence rates were 18.3 (10.3 CD, 8.7 UC, 1.2 IBDU). Median time since onset of symptoms until diagnosis was 2 months. CONCLUSIONS: The incidence rate of IBD in Vigo is the highest compared to former Spanish cohorts, especially in CD patients. Median time since onset of symptoms until diagnosis is relatively short

INTRODUCCIÓN: La incidencia de la enfermedad inflamatoria intestinal (EII) va paulatinamente en aumento. En España escasean los estudios epidemiológicos prospectivos recientes. En 2010 se inició el estudio Epicom, un estudio demográfico de cohortes de inicio de pacientes con EII no seleccionados que se desarrolla en el marco de la Organización Europea de Enfermedad de Crohn y Colitis Ulcerosa. La de Vigo es la única zona española participante. OBJETIVO: Describir la incidencia de la EII en el área de Vigo y las características fenotípicas en el momento del diagnóstico y compararlas con los datos previos disponibles sobre España. MATERIAL Y MÉTODOS: Estudio epidemiológico, descriptivo, prospectivo y demográfico. Se incluyeron todos los casos de EII incidentes durante el año 2010 en residentes de la zona de Vigo. Para definir los casos se emplearon los criterios diagnósticos de Copenhague. La población del entorno al inicio del estudio era de 579.632 habitantes. Los datos se incluyeron en la base de datos EpiCom de manera prospectiva. RESULTADOS: Se incluyó un total de 106 pacientes (57,5% varones, mediana de edad de 39,5 años). De ellos, 53 fueron diagnosticados con enfermedad de Crohn (EC), 47 con colitis ulcerosa (CU) y 6 con EII no clasificado (EIINC). La tasa de incidencia anual por 100.000 para pacientes de 15 años o más fue de 21,4 (10,8 para EC; 9,4 para CU; 1,2 para EIINC). Si se incluye la población pediátrica, la tasa de incidencia fue de 18,3 (10,3 para EC; 8,7 para CU; 1,2 para EIINC). La mediana de tiempo para la aparición de los síntomas hasta el diagnóstico fue de 2 meses.CONCLUSIONES: La tasa de incidencia de la EII en Vigo es la más alta en comparación con antiguas cohortes españolas, sobre todo en el caso de los pacientes con EC. La mediana de tiempo para la aparición de los síntomas hasta el diagnóstico es relativamente breve

Fully covered metal stents for the treatment of leaks after gastric and esophageal surgery.

OBJECTIVE: The use of fully covered metal stents (FCMS) for the treatment of benign conditions is increasing. The aim of our study was to assess the efficacy of FCMS in the management of post-operative leaks after gastric or esophageal surgery. MATERIAL AND METHODS: During a three year period (2011-2013), patients who underwent a surgery related with esophageal or gastric cancer and developed a postoperative anastomotic leak treated with FCMS were prospectively included. RESULTS: Fourteen patients were included (11 men, 3 women), with median age of 65 years. Placement of at least one stent was achieved in 13 patients (93% of cases), with initial closure of the leak in 12 of these 13 cases (92.3%). A final success (after removal of the stent) could be demonstrated in 9 cases (69.2%, intention to treat analysis); stent failed only in one case (7.7%) and there were 3 patients (23.1%) not evaluated because death before stent retrieval (not related with the endoscopic procedure). One stent were used in 9 cases (69.2%), and two in 4 (30.8%). Migration was observed in two cases (15.3%). There were no major complications related with the use of stents. There were no complications related with retrieval. CONCLUSIONS: The placement of FCMS to achieve the leak closure after esophageal or gastric surgery is an effective and probably safe alternative feasible with minor risks.

Factors associated with early virological response to peginterferon-α-2a/ribavirin in chronic hepatitis C.

AIM: To evaluate the impact of sociodemographic/clinical factors on early virological response (EVR) to peginterferon/ribavirin for chronic hepatitis C (CHC) in clinical practice. METHODS: We conducted a multicenter, cross-sectional, observational study in Hepatology Units of 91 Spanish hospitals. CHC patients treated with peginterferon α-2a plus ribavirin were included. EVR was defined as undetectable hepatitis C virus (HCV)-ribonucleic acid (RNA) or ≥ 2 log HCV-RNA decrease after 12 wk of treatment. A bivariate analysis of sociodemographic and clinical variables associated with EVR was carried out. Independent factors associated with an EVR were analyzed using a multiple regression analysis that included the following baseline demographic and clinical variables: age (≤ 40 years vs > 40 years), gender, race, educational level, marital status and family status, weight, alcohol and tobacco consumption, source of HCV infection, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and gamma glutamyl transpeptidase (GGT) (≤ 85 IU/mL vs > 85 IU/mL), serum ferritin, serum HCV-RNA concentration (< 400,000 vs ≥ 400,000), genotype (1/4 vs 3/4), cirrhotic status and ribavirin dose (800/1000/1200 mg/d). RESULTS: A total of 1014 patients were included in the study. Mean age of the patients was 44.3 ± 9.8 years, 70% were male, and 97% were Caucasian. The main sources of HCV infection were intravenous drug abuse (25%) and blood transfusion (23%). Seventy-eight percent were infected with HCV genotype 1/4 (68% had genotype 1) and 22% with genotypes 2/3. The HCV-RNA level was > 400 000 IU/mL in 74% of patients. The mean ALT and AST levels were 88.4 ± 69.7 IU/mL and 73.9 ± 64.4 IU/mL, respectively, and mean GGT level was 82 ± 91.6 IU/mL. The mean ferritin level was 266 ± 284.8 µg/L. Only 6.2% of patients presented with cirrhosis. All patients received 180 mg of peginterferon α-2a. The most frequently used ribavirin doses were 1000 mg/d (41%) and 1200 mg/d (41%). The planned treatment duration was 48 wk for 92% of patients with genotype 2/3 and 24 wk for 97% of those with genotype 1/4 (P < 0.001). Seven percent of patients experienced at least one reduction in ribavirin or peginterferon α-2a dose, respectively. Only 2% of patients required a dose reduction of both drugs. Treatment was continued until week 12 in 99% of patients. Treatment compliance was ≥ 80% in 98% of patients. EVR was achieved in 87% of cases (96% vs 83% of patients with genotype 2/3 and 1/4, respectively; P < 0.001). The bivariate analysis showed that patients who failed to achieve EVR were older (P < 0.005), had higher ALT (P < 0.05), AST (P < 0.05), GGT (P < 0.001) and ferritin levels (P < 0.001), a diagnosis of cirrhosis (P < 0.001), and a higher baseline viral load (P < 0.05) than patients reaching an EVR. Age < 40 years [odds ratios (OR): 0.543, 95%CI: 0.373-0.790, P < 0.01], GGT < 85 IU/mL (OR: 3.301, 95%CI: 0.192-0.471, P < 0.001), low ferritin levels (OR: 0.999, 95%CI: 0.998-0.999, P < 0.01) and genotype other than 1/4 (OR: 4.716, 95%CI: 2.010-11.063, P < 0.001) were identified as independent predictors for EVR in the multivariate analysis. CONCLUSION: CHC patients treated with peginterferon-α-2a/ribavirin in clinical practice show high EVR. Older age, genotype 1/4, and high GGT were associated with lack of EVR.

Complementary and alternative medicine in inflammatory bowel disease patients: frequency and risk factors.

BACKGROUND: The use of complementary and alternative medicine in inflammatory bowel disease patients is progressively increased. AIM: To evaluate the use of complementary and alternative medicine in inflammatory bowel disease patients and to know potential risk factors for their use. The subjective response of these therapies and the impact on treatment adherence were also evaluated. METHODS: Prospective, descriptive and transversal study. Inflammatory bowel disease patients were classified according to demographic and clinical characteristics. A questionnaire about the use of complementary and alternative medicine was collected. RESULTS: 705 patients were included. 126 patients (23%) had used complementary and alternative medicine. The most commonly used was herbal remedies (n=61), homoeopathy (n=36), acupuncture (n=31), kefir (n=31) and aloe vera (n=25). Factors associated with its use were extraintestinal manifestations (OR 1.69, CI 95% 1.11-2.57) and long-term evolution of the disease (OR 2.08, CI 95% 1.44-2.99). Most patients (74%) had the subjective feeling that use of complementary and alternative medicine had not improved their condition, 11 had adverse events related to its use and 11% of patients discontinued their conventional drugs. CONCLUSIONS: Use of complementary and alternative medicine in inflammatory bowel disease patients is frequent, especially in those with extraintestinal manifestations and long-term evolution. The use of these therapies was not perceived as a benefit for patients.
