Uso de la cápsula endoscópica en enfermedad inflamatoria intestinal en práctica clínica en España. Resultados de una encuesta nacional

IntroductionSmall bowel capsule endoscopy (SBCE) is a non-invasive diagnostic technique whose use in inflammatory bowel disease (IBD) has spread. A panenteric capsule, PillCam Crohn's (PCC), has recently been developed. We lack information on the availability and use of the CEID and PCC in our environment.MethodsWe conducted an electronic and anonymous survey among the members of the Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa (GETECCU) [Spanish Working Group on Crohn's Disease and Ulcerative Colitis] and the Asociación Española de Gastroenterología (AEG) [Spanish Association of Gastroenterology], consisting of 37 multiple-choice questions.ResultsOne hundred and fifty members participated, the majority dedicated to IBD (69.3%). 72.8% worked at centres with an IBD unit. 79% had SBCE available at their hospital, 14% referred patients to another centre; 22% had a PCC available, 9% referred patients to another centre. 79.3% of respondents with available SBCE used it in a small percentage of patients with IBD and 15.6% in the majority. The most frequent scenarios were suspicion of Crohn's disease (76.3%), assessment of inflammatory activity (54.7%) and assessment of the extent of the disease (54.7%). More than half (59.7%) preferentially used the Patency capsule to assess intestinal patency. Almost all respondents (99.3%) considered that training resources should be implemented in this technique.ConclusionsSBCE is widely available in Spanish hospitals for the management of IBD, although its use is still limited. There is an opportunity to increase training in this technique, and consequently its use.     

Utilidad de la cápsula endoscópica en el diagnóstico de la enfermedad injerto contra huésped gastrointestinal

Introduction and aimGraft-versus-host disease (GvHD) is a complication of hematopoietic cell transplantation, and the small bowel is one of the main targets in the gastrointestinal tract. Capsule endoscopy is a safe procedure and can be useful in the diagnosis of GvHD. The aim of the present study was to compare the diagnostic yield of capsule endoscopy with the histopathologic findings in GvHD.Materials and methodsA retrospective diagnostic test study included all the patients with suspected GvHD that underwent gastroscopy and colonoscopy, with histopathologic evaluation of the biopsies taken, and capsule endoscopy, within the time frame of July 2015 and July 2019. Capsule endoscopy findings were compared with the histopathologic diagnosis, considered the gold standard.ResultsTwenty-one patients with GvHD (7 [33%] women; 37 ± 11.9 years of age) were included, 20 (95%) of whom had acute GvHD. The median gastric transit time of the capsule was 55 minutes (20-113) and the median small bowel transit time was 261 minutes (238-434). The entire small bowel was visualized through capsule endoscopy in 17 cases (80.95%). The histopathologic findings and capsule endoscopy findings resulted in the diagnosis of GvHD in 17 and 16 cases, respectively. There was agreement between the histopathologic and capsule endoscopy findings in 18 cases (15 positive and 3 negative). Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic yield of capsule endoscopy were 88%, 75%, 94%, 60%, and 85%, respectively.ConclusionsCapsule endoscopy is a safe tool for the diagnosis of GvHD, with high sensitivity and positive predictive value, as well as moderate agreement with histopathologic findings.

A Multicenter,Randomized,Double-blind Clinical Study on Wufuxinnaoqing Soft Capsule(五福心脑清胶囊) in Treatment of Chronic Stable Angina Patients with Blood Stasis Syndrome

Objective:To confirm the efficacy and safety of Wufuxinnaoqing Soft Capsule(五福心脑清胶囊,WSC)in the treatment of chronic stable angina(blood stasis syndrome).Methods:A multicenter,randomized,double-blind,placebo-controlled trial with superiority test was designed.A total of 240 patients with chronic stable angina(blood stasis syndrome)from multiple centers were randomly and equally assigned to the treatment group and the control group.Based on standard treatment of Westem medicine,the treatment group was given WSC,while the control group was given WSC mimetic,both for 12 weeks.Observed indicators included the efficacy in angina,the efficacy in Chinese medicine syndrome,the withdrawal or reduce rate of nitroglycerin and routine safety indices.Results:After 12-week treatment,the significant effective rate and total effective rate of the treatment group were significantly better than those of the control group(23.5%vs.9.2%,64.7%vs.30.8%),respectively,with statistically significant difference(P0.01).After 12-week treatment,the decreased points and the decreased rate of angina symptom score in the treatment group were better than in the control group(5.1±4.2 points vs.2.8±3.5 points,44.9%±37.2%vs.25.4%±30.7%)respectively,with significant difference(P0.01).After 12-week treatment,the significant effective rate and total effective rate of the treatment group were better than the control group(respectively,30.3%vs.15.0%,67.2%vs.45.0%,P0.01).After 8-or 12-week treatment,the decreased points and the decreased rate of Chinese medicine syndrome score in the treatment group were better than the control group(P0.05 or P0.01).After 12-week treatment,nitroglycerin withdrawal rate and the withdrawal or reduce rate in treatment group were better than the control group(P0.01).On safety evaluation,the incidence of adverse events(7.563%vs.7.500%)and the incidence of cardiovascular events(0.840%vs.0.000%)in the treatment group were similar with the control group,and the difference was not statistically significant(P0.05).Conclusion:In treatment of chronic stable angina(blood stasis syndrome),WSC can reduce angina attacks and consumption of nitroglycerin,decrease angina severity degree,effectively relieve the blood stasis syndromes,such as chest pain,chest tightness,palpitations,dark purple tongue and other symptoms.Besides,adverse events and cardiovascular adverse events in the treatment group and the control group showed no difference.All shows that the drug is safe and effective.[This study was registered in Chinese Clinical Trial Registry(ChiCTR),with registration number:ChiCTR-TRC-14005158.]
