Abstract:
All febrile episodes (a total of 276) which occurred in 85 patients with acute myelogenous leukaemia treated in four Norwegian centres during the period 1990-1994 were studied retrospectively in order to assess the efficacy of antibiotic treatment. 72% of these episodes were initially treated with benzyl penicillin and aminoglycoside (standard treatment), while alternative empirical treatment was given in the remaining cases. The treatment was successful in 94% of the febrile episodes initially treated with standard treatment and in 96% of the episodes which received alternative antibiotics. For both types of treatment, a change to second line antibiotic regimen was made for various reasons in a majority of cases. The combination benzyl penicillin and aminoglycoside seems to be a safe empirical treatment for febrile neutropenia in patients with acute myelogenous leukaemia in our treatment centres, provided that the treatment is modified in patients with unsatisfactory clinical response.
Insights
This study found that standard antibiotic treatment, including benzyl penicillin and aminoglycoside, is effective for febrile neutropenia in acute myelogenous leukemia patients. Alternative treatments also showed high success rates, with modifications often necessary.
Area of Science:
- Hematology
- Infectious Diseases
- Clinical Pharmacology
Context:
- Febrile neutropenia is a common and serious complication in patients with acute myelogenous leukemia (AML).
- Empirical antibiotic treatment is crucial for managing febrile episodes in this immunocompromised population.
- This retrospective study analyzes treatment data from Norwegian centers between 1990 and 1994.
Purpose:
- To retrospectively assess the efficacy of empirical antibiotic treatment for febrile episodes in patients with acute myelogenous leukemia.
- To compare the success rates of standard benzyl penicillin and aminoglycoside treatment versus alternative antibiotic regimens.
- To evaluate the safety and necessity of modifying antibiotic regimens based on clinical response.
Summary:
- A total of 276 febrile episodes in 85 AML patients were analyzed.
- Standard treatment (benzyl penicillin and aminoglycoside) was used in 72% of episodes, with a 94% success rate.
- Alternative antibiotics were used in 28% of cases, achieving a 96% success rate. Regimen modifications were common for both approaches.
Impact:
- The combination of benzyl penicillin and aminoglycoside is a safe and effective empirical treatment for febrile neutropenia in AML patients.
- Clinical response monitoring and timely modification of antibiotic regimens are essential for optimal patient outcomes.
- Findings support current guidelines for managing infections in hematological malignancies.
