Clinical study on procalcitonin in septicemia of infected

Objective To study the value of procalcitonin in septicemia. Methods A total of 60 patients with sepsis, 60 local intection patients from our hospital, the level of white blood cell(WBC), neutrophil ratio(Neu%), C- reactive protein(CRP) and procalcitonin(PCT) were observed on the first day of enrollment. Results Patients with sepsis were main infection with Gram-negative bacilli(47/60); local intection patients were main infection with gram positive coccus(43/60). Patients with sepsis had a higher level of Neu%、CRP and PCT than local intection patients(all P 0.01). The area under the curve of ROC of PCT was significantly larger than others. The sensitivity and specificity of PCT was 83.3%and 86.7% respecitively on diagnosis of septicemia. Conclusion PCT has higher sensitivity and specificity than WBC、Neu% and CRP. PCT has high clinical value in septicemia.
