Influence of serum Calcium with Severity and Prognosis in Elderly Pneumonia Patients

Objective: To investigate the relationship of serum calcium with the severity of disease and prognosis in geriatric patients with pneumonia.Methods: 206 elderly patients with pneumonia admitted to EICU in our hospital were divided into two groups: sepsis group(n=155) and nonsepsis group(n=51).Patients in sepsis group were divided into two subgroups: survival group(n=91) and death group(n=64).Serum calcium,plasma albumin,C-reactive protein and leukocyte count were measured.Results: Compared with nonsepsis group,serum calcium was decreased in sepsis group(P0.01).C-reactive protein and leukocyte count in sepsis group were heightened(P0.01).Compared with survival group,serum calcium was much lower in death group(P0.01).C-reactive protein was higher in death group(P0.05).Leukocyte counts were similar in the two subgroups(P0.05).There was a positive correlation between serum calcium and plasma albumin.Conclusion: Serum calcium can be helpful to predict the prognosis of geriatric people with pneumonia.
