Ceftazidime in the therapy of serious Gram-negative bacillary infections
Abstract:
Eighteen patients were evaluated after treatment with ceftazidime: these included nine nosocomial lower respiratory tract infections, four soft tissue infections, three bacteraemias and two bone infections. Thirty-five bacterial pathogens were isolated from these 18 patients. Two were resistant to ceftazidime and required alternative therapy. Sixteen of the 18 evaluable patients had a favourable response to ceftazidime. Seven of eight patients with Pseudomonas aeruginosa lower respiratory tract infections responded favourably. Fifteen possible complications were observed in ten of 23 patients who received ceftazidime. In three patients ceftazidime was discontinued due to possible complications of therapy. This trial provides preliminary support for the use of ceftazidime as an alternative to aminoglycosides in the treatment of serious infections caused by Gram-negative organisms, including Ps. aeruginosa.
Insights
Ceftazidime demonstrated a favorable response in 16 of 18 patients with serious Gram-negative infections, including Pseudomonas aeruginosa. This antibiotic shows promise as an alternative to aminoglycosides for treating severe bacterial pathogens.
Area of Science:
- Infectious Diseases
- Clinical Pharmacology
- Bacteriology
Background:
- Serious bacterial infections pose significant treatment challenges.
- Aminoglycosides are commonly used for Gram-negative infections but can have toxicity.
- Ceftazidime is a third-generation cephalosporin with broad-spectrum activity.
Purpose of the Study:
- To evaluate the efficacy and safety of ceftazidime in treating serious infections.
- To assess ceftazidime's utility as an alternative to aminoglycosides.
- To investigate ceftazidime's effectiveness against Pseudomonas aeruginosa.
Main Methods:
- A clinical trial involving 18 patients with various serious infections.
- Isolation and susceptibility testing of 35 bacterial pathogens.
- Monitoring of patient response and adverse events.
Main Results:
- 16 out of 18 evaluable patients showed a favorable response to ceftazidime.
- Effective treatment was observed in seven of eight patients with Pseudomonas aeruginosa lower respiratory tract infections.
- Two bacterial isolates were resistant to ceftazidime, necessitating alternative treatment.
Conclusions:
- Ceftazidime is a potentially effective alternative to aminoglycosides for serious Gram-negative infections.
- The drug shows particular promise for infections caused by Pseudomonas aeruginosa.
- Further investigation is warranted to confirm safety and efficacy in larger patient cohorts.
