Is procalcitonin a useful biomarker to predict severe acute cholangitis : a single-center prospective study?
Procalcitonin predicted severe acute cholangitis better than conventional biomarkers. Severe cases for which urgent biliary drainage is indicated might be identified on admission on the basis of the cutoff values for procalcitonin suggested in this study.
While it is only possible to speculate on the possible reasons, the existence of a possible bias in the published literature according to funding source must be given serious consideration.
