1Azathioprine monotherapy withdrawal in inflammatory bowel diseases: A retrospective mono-centric study显示文摘BACKGROUND There is no consensus on the recommended duration of and optimal time to stop azathioprine(AZA)therapy in inflammatory bowel disease(IBD).Determining the optimal duration and cessation time can help to balance the risks of long-term intake with the possibility of relapse after cessation.AIM To describe the events following AZA cessation.METHODS Retrospective analysis was performed to examine data from adult patients affected by IBD who were followed at the University of Padua and had started but then discontinued AZA between 1995 and 2022.Data on therapy duration,reasons for cessation,and type of relapse after cessation were collected.Cox regression models were used to estimate the risk of relapse in different subgroups.RESULTS A total of 133 ulcerative colitis patients and 141 Crohn’s disease patients were included.Therapy with AZA was stopped in the 1st year in approximately 34%of patients but was continued for more than 10 years in approximately 10%of cases.AZA discontinuation was due to primary failure or disease relapse in 30%of patients and due to disease remission in 25.2%of patients.Most of the remaining cases stopped AZA therapy due to side effects(primarily clinical intolerance,cytopenia,and pancreatic disease).Patients who stopped AZA for clinical remission had an 83%lower risk of relapse during the observation time than other groups,with a relapse-free rate of 89%after 1 year and 79%after 2 years.CONCLUSION AZA administration is effective and safe,but it requires careful monitoring for potential minor and major side effects.Only 10%of patients who achieved remission with AZA needed a new treatment within 1 year of drug interruption.Martina Crepaldi Daria Maniero Alessandro Massano Margherita Pavanato Brigida Barberio Edoardo Vincenzo Savarino Fabiana Zingone 2023World Journal of Gastroenterology2023,29,27:0
