Abstract：Objective To study efficiency of C reactive protein (CRP) and procalcitonin(PCT) in elderly patients with community acquired pneumonia(CAP).Methods Totally 124 cases of elderly CAP patients were selected in our hospital,PCT,CRP and pneumonia severity index (PSI) score were examed after admission,the difference of CRP,PCT and PSI score were compared between the death group and the survival group,those were compared between the severe pneumonia and no severe pneumonia group too; the content of CRP,PCT and PSI score correlation analysis were carried out.Results The PCT,CRP levels and PSI scores of death group were greater than those in survival group [PCT:(11 ±4) μg/L vs (9 ±4) μg/L,CRP:(28 ± 13) μg/L vs (23 ± 10) mg/L,PSI:(86 ± 27) scores vs (73 ± 27) scores,P ＜ 0.05] ; the level of PCT,CRP hand PSI scores of severe pneumonia patients were greater than in no severe pneumonia patients.Correlation analysis showed that PCT,CRP levels had positive correlation with PSI score (r =0.64,0.71,P ＜ 0.05).Conclusion The PCT and CRP levels have certain prognostic evaluation function for elderly patients with CAP ; high levels of PCT and CRP suggest a poor prognosis.
