title: Procalcitonin Strip Test as an Independent Predictor in Acute Pancreatitis.
abstract: Plasma procalcitonin (PCT) is a highly specific marker for the diagnosis of bacterial infection and sepsis. Studies have demonstrated its role in the setting of sepsis and acute pancreatitis. This study aims to analyze and compare the prognostic efficacy of plasma procalcitonin strip test in acute pancreatitis. A prospective study was conducted in the department of general surgery from June 2012 to June 2013. Plasma procalcitonin was estimated by the semiquantitative strip test. The study included a total of 50 patients diagnosed to have acute pancreatitis. Data was collected and statistically analyzed using SPSS version 17. Thirty-nine out of the 50 patients (78 %) were males with a mean age of 46.8 years (range, 25-78 years) and 25 patients (50 %) had ethanol-induced pancreatitis, while 13 patients (26 %) had gall stone pancreatitis. Plasma PCT values were found to correlate better than CRP levels and total leukocyte count with the total duration of hospitalization, ITU, and ICU stay, as well as with the progression to severe acute pancreatitis. A cut off for plasma PCT of >2 ng/mL was found to be 100 % sensitive and 100 % specific and a cut off for CRP of >19 mg/dL was 70 % sensitive and 65 % specific for predicting the progression to severe acute pancreatitis. Plasma PCT also correlated well with antibiotic requirement. A cut off value of >0.5 ng/mL for plasma PCT was 100 % sensitive and 80 % specific and a cut off value of >18 mg/dL for CRP was 86 % sensitive and 63 % specific for predicting antibiotic requirement. Plasma procalcitonin is an early and reliable prognostic indicator in acute pancreatitis. The procalcitonin strip test is a rapid test which is useful in analyzing prognosis in patients with acute pancreatitis.
