BACKGROUND: SARS-CoV-2 is the cause of a pandemic with high mortality. In the present study, the effects of the lipase/lymphocyte ratio on mortality were investigated in cases diagnosed with Covid-19 and acute pancreatitis. METHODS: A total of 21 patients who were diagnosed with Covid-19 and acute pancreatitis, 34 patients who were not diagnosed with COVID-19 but diagnosed with acute pancreatitis, and 55 healthy control groups were divided into 3 groups and included in the study retrospectively. The patients who had positive RT-PCR (real-time polymerized chain reaction) test results were included in the study. Complete blood count and biochemical values of the patients were compared with those of the control group. RESULTS: When the data of the cases diagnosed with COVID-19 and acute pancreatitis were examined retrospectively, the amylase, lipase, lipase/lymphocyte ratio, and D-dimer levels were found to be signifi cantly higher than in the control group (p < 0.01). In the ROC analysis, the amylase, lipase, and lipase/lymphocyte ratio had a high AUC (area under the curve) value (0.993 / 0.949 / 0.978, respectively). CONCLUSION: The lipase/lymphocyte ratio can be used in cases diagnosed with Covid-19 and acute pancreatitis to predict mortality (Tab.
