| 标题： The Current Treatment of Ulcerative Colitis in the USA | |
| 摘要：
Ulcerative colitis (UC) is a chronic disease characterized by diffuse mucosal inflammation limited to the colon. UC affects approximately 500,000 individuals in the US with an incidence of 8 – 12 per 100,000 population per year. UC accounts for 1/4 million physician visits annually, 30,000 hospitalizations, and loss of over 1 million workdays per year. The direct medical costs alone exceed 4 billion dollars annually. Although some UC patient might eventually need surgery for medically refractory disease, chronic corticosteroids use, dysplasia, or colorectal cancer, many UC patients are still able to achieve clinical remission and mucosal healing with current available medical treatments. This review will focus on current available medicines that are used in the United States of America (USA) to treat UC. It will discuss corticosteroids, mesalamine, thiopurines, calcineurin inhibitors, anti- tumor necrosis factor (TNF) monoclonal antibodies, anti-α4β7 integrins monoclonal antibodies, Janus kinases inhibitor, and biosimilars. The review will discuss the current algorithm of medically treating UC in the USA. It will also provide evidence of using these medicines in treating UC based on the most recent clinical trials. At the last, the review will also compare the difference of medical treatments between Crohn’s disease and UC.
