A retrospective study of infections in neutropenic patients
1Meenakshi Mission Hospital and Research Center, Madurai.
Abstract:
This is a retrospective non-randomised study of 37 episodes of infections in neutropenic patients (grades III and IV myelosuppression). The commonest presentation of infection in these patients was fever which was followed by diarrhoea. Infection was documented bacteriologically in 22.6% of episodes and blood culture was positive in 5.5% of episodes only. More than half episodes (56.8%) received quinolone and aminoglycoside combination, 24.3% 3rd generation cephalosporin and aminoglycoside combination and 18.9% combination of quinolone and cephalosporin in cross over. These combinations of antibiotics were successful in 90.5% with quinolone arm, 44.4% with cephalosporin arm and 71.4% in cross over arm. This difference in success was statistically significant and is independent of grade of neutropenia.
Insights
This study found that quinolone-based antibiotic combinations were more effective in treating infections in neutropenic patients compared to cephalosporin combinations. Fever and diarrhea were common symptoms in these patients.
Area of Science:
- Infectious Diseases
- Hematology
- Pharmacology
Background:
- Neutropenic patients are highly susceptible to infections.
- Fever and diarrhea are common clinical presentations of infection in this population.
- Bacteriological documentation of infection, including blood cultures, is often low.
Purpose of the Study:
- To evaluate the efficacy of different antibiotic combinations in treating infections in neutropenic patients.
- To compare the success rates of quinolone-based versus cephalosporin-based antibiotic regimens.
Main Methods:
- Retrospective, non-randomized study of 37 infection episodes in neutropenic patients (grades III and IV myelosuppression).
- Analysis of antibiotic regimens used: quinolone/aminoglycoside, 3rd generation cephalosporin/aminoglycoside, and quinolone/cephalosporin combinations.
- Assessment of treatment success rates for each antibiotic arm.
Main Results:
- Quinolone-containing antibiotic combinations demonstrated significantly higher success rates (90.5%) compared to cephalosporin-based combinations (44.4%).
- Cross-over arm also showed a high success rate (71.4%).
- Treatment success was independent of the grade of neutropenia.
Conclusions:
- Quinolone-based antibiotic combinations are more effective for treating infections in neutropenic patients.
- Empirical antibiotic selection should consider the efficacy of quinolone regimens in this vulnerable patient group.
- Further prospective studies may be warranted to confirm these findings.
