| 1 | Clinical epidemiology of ulcerative colitis in Arabs based on the Montréal classification显示文摘AIM:To determine the clinical,epidemiological and phenotypic characteristics of ulcerative colitis(UC)in Saudi Arabia by studying the largest cohort of Arab UC patients.METHODS:Data from UC patients attending gastroenterology clinics in four tertiary care centers in three cities between September 2009 and September 2013were entered into a validated web-based registry,inflammatory bowel disease information system(IBDIS).The IBDIS database covers numerous aspects of inflammatory bowel disease.Patient characteristics,disease phenotype and behavior,age at diagnosis,course of the disease,and extraintestinal manifestations were recorded.RESULTS:Among 394 UC patients,males comprised51.0%and females 49.0%.According to the Montréal classification of age,the major chunk of our patients belonged to the A2 category for age of diagnosis at17-40 years(68.4%),while 24.2%belonged to the A3category for age of diagnosis at>40 years.According to the same classification,a majority of patients had extensive UC(42.7%),35.3%had left-sided colitis and29.2%had only proctitis.Moreover,51.3%were in remission,16.6%had mild UC,23.4%had moderate UC and 8.6%had severe UC.Frequent relapse occurred in17.4%patients,infrequent relapse in 77%and 4.8%had chronic disease.A majority(85.2%)of patients was steroid responsive.With regard to extraintestinal manifestations,arthritis was present in 16.4%,osteopenia in 31.4%,osteoporosis in 17.1%and cutaneous involvement in 7.0%.CONCLUSION:The majority of UC cases were young people(17-40 years),with a male preponderance.While the disease course was found to be similar to that reported in Western countries,more similarities were found with Asian countries with regards to the extent of the disease and response to steroid therapy. | Othman R Alharbi Nahla A Azzam Ahmed S Almalki Majid A Almadi Khalid A Alswat Nazia Sadaf Abdulrahman M Aljebreen | 2014 | World Journal of Gastroenterology2014，20，46： | 2 |
