Abstract

The present study investigated the clinical effect of antibiotic de-escalation therapy in elderly patients with chronic obstructive pulmonary disease (COPD) complicated with severe pneumonia. According to the parity method of hospitalization number, 86 cases were selected and divided into the observation and control group with 43 cases each. Based on empirical antibiotic application, levofloxacin and cephalosporin antibiotics were used in the control group. After treatment for 3 days, the regimen was adjusted to antibiotics active against Gram‑positive (G+) and Gram‑negative (G-) bacteria such as the third or fourth generation cephalosporin antibiotics, combined with aminoglycoside, or macrolide antibiotics according to their effects. The treatment effects were re‑evaluated after 3‑7 days. Finally, broad-spectrum antibiotics such as imipenem were chosen or adjusted by bacterial cultures and drug sensitivity results in the control group. Patients in the observation group were treated according to the principle of antibiotic de‑escalation therapy. Antibiotics active against G+ and G‑ bacteria were chosen as the first round of medication. After 3 days, broad‑spectrum antibiotics such as imipenem were added to the treatment regimen. After 7 days, the treatment was changed to narrow spectrum antibiotic administration if the disease was in remission, and the antibiotic regimen was adjusted based on bacterial culture and drug sensitivity results. The treatment results were compared. The mechanical ventilation rate, antibiotic courses, number of antibiotics used, and mortality of the observation group were significantly lower than those in the control group (P<0.05). After treatment, lung function improved, partial pressure of oxygen and blood oxygen saturation increased, and partial pressure of carbon dioxide decreased in both groups. The improvement of all of the above parameters were more significant in the observation group (P<0.05). After treatment, the ratio of neutrophils over white blood cells and C‑reactive protein levels of the two groups decreased, respiratory failure index (RFI) increased, and the changes were significantly more pronounced in the observation group (P<0.05). In conclusion, following the antibiotic de‑escalation principle to treat older patients with COPD complicated with severe pneumonia can reduce the number of antibiotics required, improve lung function and clinical effects, and is safe and effective.
