Summary
High doses or prolonged use of cephapirin can cause reversible neutropenia, a serious blood disorder. Hematologic monitoring is recommended during extended cephapirin therapy to prevent adverse effects.
Area of Science:
- Pharmacology
- Hematology
- Clinical Medicine
Background:
- Cephapirin is an antibiotic used in clinical settings.
- Neutropenia is a condition characterized by an abnormally low level of neutrophils.
Purpose of the Study:
- To investigate the incidence and characteristics of cephapirin-induced neutropenia.
- To identify risk factors associated with the development of neutropenia during cephapirin treatment.
Main Methods:
- Retrospective analysis of 132 patients treated with cephapirin.
- Comparison of demographic and treatment data between patients who developed neutropenia and those who did not.
- Statistical analysis to determine significant risk factors.
Main Results:
- Five cases (3.5%) of reversible neutropenia, including 3 cases of agranulocytosis, were observed.
- Neutropenia was associated with higher daily and total doses, and longer duration of cephapirin therapy (p < 0.05).
- The incidence of neutropenia exceeded 26.3% when the total dose surpassed 90g (p < 0.001).
Conclusions:
- Cephapirin can induce reversible neutropenia, particularly with high doses and prolonged administration.
- Hematologic monitoring is advisable for patients receiving long-term or high-dose cephapirin therapy.
- Early detection and intervention are crucial for managing antibiotic-induced hematologic disorders.
