Pulmonary infections in elderly patients: treatment with cefazolin
Abstract:
The effects of cefazolin were studied in 15 hospital patients (average age, 67) with respiratory-tract infections. The infections were chiefly bronchopneumonia caused by organisms such as D. pneumoniae, Staph. aureus, or E. coli. In 13 of the 15 patients the results were excellent to good (eradication of the primary pathogen and clinical improvement); in the other 2 patients the response was fair. Intramuscular injection was well tolerated and only one patient complained of pain at the site of injection; no other adverse clinical effects were observed. In the laboratory determinations, including liver and kidney function tests, the only abnormalities were 2 cases in which the Coombs' test gave positive results without hemolysis. Cefazolin seems to be a safe and effective antibiotic for the treatment of respiratory-tract infections caused by cefazolin-susceptible organisms.
Insights
Cefazolin effectively treated respiratory infections in 15 patients, showing good to excellent results in most cases. This antibiotic demonstrated a favorable safety profile with minimal side effects, making it a viable treatment option.
Area of Science:
- Infectious Diseases
- Pharmacology
- Internal Medicine
Background:
- Respiratory-tract infections pose a significant health burden.
- Bacterial pathogens like D. pneumoniae, Staph. aureus, and E. coli are common causes.
- Effective antibiotic therapy is crucial for managing these infections.
Purpose of the Study:
- To evaluate the efficacy and safety of cefazolin in treating hospital patients with respiratory-tract infections.
- To assess clinical outcomes and adverse effects associated with cefazolin treatment.
Main Methods:
- A study involving 15 hospitalized patients with respiratory-tract infections.
- Treatment administered via intramuscular injection of cefazolin.
- Clinical response and laboratory parameters (including liver and kidney function, Coombs' test) were monitored.
Main Results:
- Excellent to good results were observed in 13 out of 15 patients.
- Clinical improvement and eradication of primary pathogens were noted.
- The drug was well-tolerated, with only one patient reporting injection site pain; no other adverse effects were seen.
- Two patients had positive Coombs' tests without hemolysis; liver and kidney function tests remained normal.
Conclusions:
- Cefazolin is a safe and effective antibiotic for treating respiratory-tract infections.
- It is particularly useful against infections caused by cefazolin-susceptible organisms.
- The intramuscular route of administration is well-tolerated.
