To investigate the application value of serum procalcitonin and high sensitivity C-reactive protein (hsCRP) in children with bronchial pneumonia.

Total of 80 specimens from 80 cases with infection (40 cases with general infection and 40 cases with severe infection) were collected, while 40 cases from physical examination center were collected as control group. The levels of PCT, hsCRP and WBC counts were detected, and the score of sepsis were calculated, respectively. The levels of PCT, hsCRP, WBC and sepsis score were compared among two infection groups and the control group, respetively, and the levels of PCT, hsCRP, WBC and sepsis score of two infection groups were compared before and after treatment, respectively.

Before treatment, the levels of PCT, hsCRP, WBC and sepsis score of patients in infection group were significantly different compared with those of control group (all P < 0.05). After treatment, all indexes of patients in infection group had significant differences compared with the indexes before treatment (all P < 0.05). The levels of PCT, hsCRP, WBC counts of patients in severe infection had significant differences compared with those in general infection group after treatment (all P < 0.05), but sepsis score had no significant differences between the two groups (t = 0.821, P = 0.241).

Serum PCT and hsCRP were positively correlated with infantile bronchial pneumonia severity, which could guide the treatment and curative effect of bronchopneumonia.
