ABSTRACT
Objective To investigate the clinical value of prealbumin (PA) and C-reactive protein (CRP) level for the diagnosis of children patients with bacterial community acquired pneumonia (CAP).Methods Seventy-two children with bacterial CAP (CAP group) between July 2012 and December 2013 were enrolled in the study.Fifty healthy children were selected as healthy control group.The level of serum PA and CRP were measured by flow cytometry and turbidimetric immunoassay respectively.The results were compared.Results Before treatment,the level of CRP in CAP group was higher than that in healthy control group,and the level of PA in CAP group was lower than that in healthy control group,there was significant difference (P ＜ 0.01).The level of white blood cell count and the rate of neutrophilic granulocyte in CAP group was higher than that in healthy control group,but there was no significant difference(P ＞ 0.05).After treatment,the level of CRP in CAP group was decreased and the level of PA was increased,there was significant difference (P ＜ 0.05).Pearson analysis showed that the level of CRP in CAP patients had negative relationship with the level of PA (r =-0.613,P ＜ 0.01).Conclusion Detection of serum PA and CRP contributes to clinical diagnosis of children bacterial CAP and evaluation of anti-infection effect.
ABSTRACT
Objective To explore the relationships between antithrombinⅢ(AT-Ⅲ) and D-dimer (DD) level with pediat-ric critical illness score (PCIS) in children with sepsis, and to evaluate the values in assessing the severity of illness. Methods Sixty-one children with sepsis were included in this study. Within 24 hours after admission, blood samples were tested for the ac-tivity of AT-Ⅲ and DD level. The PCIS was calculated. According to PCIS, the patients were divided into extremely critical group (<70), critical group (71-80) and non-critical group (80-100). According to the prognosis, the patients were divided into survival and death groups. The differences of the activity of AT-Ⅲand DD were compared and the relationship with PCIS were analyzed. Results The activity of AT-Ⅲ was lower and DD level was higher in critical group than in non-critical group (P<0.01) and the changes in extremely critical group were more evident than those in critical group. The activity of AT-Ⅲand PCIS were positively correlated (r=0.548, P<0.01).The DD level and PCIS was negatively correlated (r=-0.657, P<0.01). Compared with survival group, the level of DD was significantly higher in death group (P<0.01), and PCIS and the activity of AT-Ⅲwere significantly lower in death group (P<0.05). Conclusions The patients with sepsis have dysfunctions of coagulation. The activity of AT-Ⅲ, DD level are correlated with illness severity, and can be useful for assessing the severity of sepsis.
