To investigate the clinical diagnostic value of procalcitonin after liver transplantation in patients with bacterial pneumonia. We divided 49 patients who operated liver transplantation into two groups, which were bacterial pneumonia infection group and non-bacterial pneumonia group. Extracted serums to detect procalcitonin and C-reactive protein, the difference of results were compared by ROC curve. PCT detection in patients after liver transplantation who complicated bacterial pneumonia showed a statistically significant difference (P < 0.05). CRP detection in patients after liver transplantation who complicated bacterial pneumonia showed no significant difference (P > 0.05), compared with patients with non-bacterial pneumonia. With the development of pneumonia, PCT of bacterial pneumonia group increased significantly, sensitivity and specificity difference were statistically significant (P < 0.05), compared with CRP. Procalcitonin was more sensitive to detect the development of patients after liver transplantation with bacterial pneumonia, compared with C-reactive protein, and provided better and rapid clinical diagnostic.
