Summary
Serial C-reactive protein (CRP) monitoring can guide early antibiotic discontinuation for intracranial abscesses. A normalized CRP level, alongside clinical and CT scan improvements, indicates successful treatment, avoiding prolonged antimicrobial therapy.
Area of Science:
- Neurology
- Infectious Diseases
- Biochemistry
Background:
- Intracranial abscesses require prompt diagnosis and treatment.
- Prolonged antimicrobial therapy is common but may not always be necessary.
- Monitoring inflammatory markers can aid treatment decisions.
Purpose of the Study:
- To evaluate the utility of serial C-reactive protein (CRP) measurements in guiding the duration of antimicrobial treatment for intracranial abscess.
- To determine if CRP normalization correlates with successful treatment and recovery.
Main Methods:
- Serial CRP levels were measured in 26 patients with intracranial abscesses post-surgery and antimicrobial therapy.
- CRP trends were correlated with clinical condition, CT scan findings, and treatment outcomes.
- Antibiotic duration was guided by CRP normalization, clinical improvement, and CT scan resolution.
Main Results:
- Elevated CRP was observed in 77% of patients.
- Normalized CRP correlated with good recovery.
- Persistently high CRP indicated abscess reformation in 12% of patients.
- Transient CRP rise was linked to deep venous thrombosis in 8% of patients.
- Mean antibiotic duration was 20 days (range 11-30 days).
Conclusions:
- Serial CRP monitoring is a valuable tool for guiding early discontinuation of antibiotics in intracranial abscess treatment.
- Combining CRP normalization with clinical and radiological evidence allows for safe shortening of antimicrobial therapy.
- No recurrences were observed in the study cohort with a median follow-up of 21 months.
