Clinical Report: Antibiotic Falls Short in Disc-Related Back Pain
Overview
A randomized clinical trial found that amoxicillin-clavulanate did not significantly reduce pain compared to placebo in patients with chronic low back pain and disc herniation at 12 months. The study included 170 participants.
Background
Chronic low back pain is a leading cause of disability worldwide, and effective treatment options are limited. Antibiotic therapy has been explored as a potential intervention, particularly for patients with disc herniation. However, the evidence supporting its use remains mixed.
Data Highlights
No significant differences in pain reduction were observed between the amoxicillin-clavulanate and placebo groups at 12 months.
Key Findings
- Amoxicillin-clavulanate did not reduce pain more than placebo at 12 months (adjusted mean difference 0.06 points).
- Disability scores did not differ between groups at 12 months.
- Adverse events were reported by 40% of patients in the antibiotic group compared to 23.5% in the placebo group.
- No significant benefits were found in prespecified subgroup analyses for patients with Modic changes.
- Adherence to medication was high, with 83% of the antibiotic group taking over 80% of their prescribed medication.
Clinical Implications
The findings indicate that routine use of antibiotics for chronic low back pain with disc herniation is not supported by the evidence.
Conclusion
This trial adds to the evidence regarding the efficacy of antibiotics for chronic low back pain associated with disc herniation.
