Cefoperazone sodium/sulbactam sodium piperacillin sodium/tazobactam sodium for treatment of respiratory tract infection in elderly patients.

BACKGROUND

Respiratory tract infections in the elderly are difficult to cure and can easily recur, thereby posing a great threat to patient prognosis and quality of life.

AIM

To investigate the therapeutic effects of different antibiotics in elderly patients with respiratory tract infection.

METHODS

Seventy-four elderly patients with respiratory tract infection were randomly allocated to a study ( = 37; treated with cefoperazone sodium/sulbactam sodium) or control ( = 37; treated with piperacillin sodium/tazobactam sodium on the basis of routine symptomatic support) group. Both groups were treated for 7 d. Time to symptom relief (leukocyte recovery; body temperature recovery; cough and sputum disappearance; and rale disappearance time), treatment effect, and laboratory indexes [procalcitonin (PCT), C-reactive protein (CRP), white blood cell count (WBC), and neutrophil percentage (NE)] before and 7 d after treatment and the incidence of adverse reactions were assessed.

RESULTS

In the study group, the time to WBC normalization (6.79 ± 2.09 d), time to body temperature normalization (4.15 ± 1.08 d), time to disappearance of cough and sputum (6.19 ± 1.56 d), and time to disappearance of rales (6.68 ± 1.43 d) were shorter than those of the control group (8.89 ± 2.32 d, 5.81 ± 1.33 d, 8.77 ± 2.11 d, and 8.69 ± 2.12 d, respectively; = 0.000). Total effective rate was higher in the study group (94.59% 75.68%, = 0.022). Serum PCT (12.89 ± 3.96 μg/L), CRP (19.62 ± 6.44 mg/L), WBC (20.61 ± 6.38 × 10/L), and NE (86.14 ± 7.21%) levels of the study group before treatment were similar to those of the control group (14.05 ± 4.11 μg/L, 18.79 ± 5.96 mg/L, 21.21 ± 5.59 × 10/L, and 84.39 ± 6.95%, respectively) with no significant differences ( = 0.220, 0.567, 0.668, and 0.291, respectively). After 7 d of treatment, serum PCT, CRP, WBC, and NE levels in the two groups were lower than those before treatment. Serum PCT (2.01 ± 0.56 μg/L), CRP (3.11 ± 1.02 mg/L), WBC (5.10 ± 1.83 × 10/L), and NE (56.35 ± 7.17%) levels were lower in the study group than in the control group (3.29 ± 0.64 μg/L, 5.67 ± 1.23 mg/L, 8.13 ± 3.01 × 10/L, and 64.22 ± 8.08%, respectively; = 0.000). There was no significant difference in the incidence of adverse reactions between the groups (7.50% 12.50%, = 0.708).

CONCLUSION

Piperacillin sodium/tazobactam sodium is superior to cefoperazone sodium/ sulbactam sodium in the treatment of elderly patients with respiratory tract infection with a similar safety profile.
