OBJE CTIVE To investigate the clinical characteristics of a dverse drug reactions of asparaginase-associated pancreatitis（AAP），so as to provide reference for clinical safe medication. METHODS Analysis and identification were performed on a severe adverse reaction case of acute pancreatitis complicated with diabetic ketoacidosis and liver injury in a patient with acute lymphoblastic leukemia in our hospital after using pegaspargase. Retrieved from Wanfang database ，CNKI，PubMed and Embase database，case reports of AAP were collected and summarized in terms of patient demographics ，drug use ，incubation period and adverse reaction outcome. Combined with this case ，the disease characteristics and potential risk factors of AAP were analyzed and discussed. RESULTS After analysis and identification ，it was determined that AAP occurred in this patient. A total of 47 case reports were retrieved from the database ，and a total of 52 patients（including this patient ）were included in the analysis ，including 29 males and 23 females，mainly minors （65.4％）. L-asparaginase was the main asparaginase preparation that causes AAP （80.8％）. Gastrointestinal symptoms were the main prodromal symptoms （92.3％），which could be accompanied by other asparaginase related adverse reactions. AAP could occur after 1-33 times of administration ，and the median latency was 14 days after administration；compared with children ，median latency of AAP in adult patients was shortened significantly （11 d vs. 16 d，P＝ 0.049）；the median latency of AAP had longer tendency in patients treated with pegaspargase than that of L-asparaginase （17 d vs. 12.5 d，P＝0.490）. Of the cases included in the analysis ，8 patients died due to AAP ，1 of which was related to re-exposure to asparaginase preparations. CONCLUSIONS Acute pancreatitis is a serious and potentially fatal adverse drug reaction of ； asparaginase preparations. Clinical medical staff should pay attention to the characteristics of AAP ，consider the possibility ： of AAP when the patients have gastrointestinal symptoms and do a good job in patient education and pharmaceutical care to minimize the damage caused by AAP to patients.
