Procalcitonin was measured daily by a semi-quantitative immunoassay in the study group. Patients were randomly assigned into 2 groups including a PCT-guided group (study group) and a prophylactic antibiotic therapy (control group). Antibiotic therapy in the study group was not applied until clinical signs and symptoms of infection appeared (PCT value was >0.5ng/ml). We discontinued the antibiotic therapy if clinical signs and symptoms of infection improved and PCT was <0.5ng/ml over 3 days. In the control group, antibiotic therapy was administrated for 2 weeks, or antibiotic therapy was continued because of confirmed infection until clinical signs and symptoms of infection disappeared over 3 days.RESULTS: In the study group (35 patients), the duration of antibiotic therapy and hospitalization was significantly shorter than the control group (36 patients) (10.89±2.85 versus 16.06±2.48 days, p<0.001, and 16.66±4.02 days versus 23.81±7.56 days, p<0.001) without negative clinical effects and the cost of hospitalization was significantly lower.CONCLUSIONS: Procalcitonin is a helpful and safe tool for guiding duration of antibiotic treatment in patients with severe acute pancreatitis.
