Observation of detection of serum calcitonin original (PCT) in the diagnosis of pediatric infectious pneumonia

Abstract

Objective To observe the serum calcitonin original (PCT) detection in the diagnosis of children with infectious pneumonia. Methods From March 2014 to April 2015, 96 children with infectious pneumonia were selected, including bacterial pneumonia in 43 cases, 26 cases of viral pneumonia, 27 cases of Mycoplasma pneumonia.50 healthy children were selected as control group.All children received serum calcitonin original test, PCT test was applied in the diagnosis of children with infectious pneumonia. Results The PCT level in children with bacterial pneumonia group was(3.84±3.57)μg/L, which was obviously higher than (0.12±0.03)μg/L of healthy children, (0.74±0.13)μg/L of children with viral pneumonia and (1.07±0.08)μg/L of pure chlamydia pneumonia patients(F=6.120, P=0.013). Before treatment, the level of serum PCT in children with bacterial pneumonia was significantly higher than that in normal children[(3.84±3.57)μg/L vs.(0.12±0.03)μg/L, t=6.987, P=0.000]. After treatment, the results of PCT detection in serum of children with bacterial pneumonia was significantly lower[(3.84±3.57)μg/L vs.(0.16±0.03)μg/L, t=6.978, P=0.000)]. Conclusion Serum calcitonin original detection can effectively help the differential diagnosis of pediatric infectious pneumonia, has clinical application value.
