ETHNIC DIVERSITY AND CLINICAL CHARACTERISTICS OF HOSPITALIZED PATIENTS WITH ACUTE PANCREATITIS

Background Previous studies have shown a correlation between acute pancreatitis and several different risk factors that vary in different countries and ethnic groups. The aims of this study are to examine the clinical characteristics and outcomes of acute pancreatitis in patients of Jewish and Bedouin origin. Methods We performed a retrospective cohort study of patients hospitalized with acute pancreatitis in the Soroka University Medical Center between the years 2012 and 2016 and compared two groups of patients: patients of Jewish and Bedouin origin. The primary outcome was a composite outcome consisting of 30-days mortality, ICU admission, complications (defined as necrotizing pancreatitis or pseudocyst formation), surgery due to these complications and 30-days re-admission due to pancreatitis. Results A total of 560 patients were included, 483 patients (86.3%) of Jewish origin and 77 patients (13.7%) of Bedouin origin. The most common cause in both groups was biliary pancreatitis: 49.7% among Jewish, 61% among Bedouin. In our study alcohol consumption, the most common worldwide risk factor of pancreatitis, accounts for only a small percentage of the disease in the Jewish population (5.6%) and does not exist in the Bedouin population. We found no significant differences in outcomes between the two groups. Conclusions Biliary pancreatitis was the most common cause in both groups of patients. The important finding of our study is that alcohol use is a minor cause of acute pancreatitis in the Negev. Moreover, it is uncommon in the Jewish population and is completely non-existent among Bedouins. No differences were found in the primary outcomes between the two groups.
