Evaluating the Efficacy of Antibiotic Therapy in Non-responsive Sacroiliitis: A Comparative Study

TL;DR

This study found that adding antibiotics to standard treatments for sacroiliitis does not improve recovery or pain relief in patients unresponsive to usual therapies.

Contribution

The study provides evidence against the efficacy of antibiotic therapy in non-responsive sacroiliitis cases.

Findings

No significant difference in JOA scores between antibiotic and non-antibiotic groups at one and three months.

Antibiotic use did not improve recovery rates or functional outcomes in non-responsive sacroiliitis patients.

Adverse effects from antibiotics were not significant.

Abstract

Background: Sacroiliitis, characterized by inflammation of the sacroiliac joints, poses significant challenges in management, especially in patients unresponsive to standard therapies like non-steroidal anti-inflammatory drugs (NSAIDs) and physical therapy. This study aimed to evaluate the efficacy of antibiotic therapy in such patients, addressing a critical gap in the current treatment approach.

Methods: A total of 360 patients with lower back pain who presented to the outpatient department (OPD) of the Department of Orthopedics of a medical college in Northern India for six months were included in this study. With meticulous history taking, clinical examination, and radiological evaluation, 59 patients were diagnosed with sacroiliitis, out of which 31 were males and 28 were females, aged between 20 and 40 years, and were enrolled in this cross-sectional comparative study. Patients were divided into two groups: a control group (21 patients) receiving conventional treatment without antibiotics and a study group (38 patients) receiving conventional treatment plus antibiotics (who gave consent for treatment with antibiotics). The primary outcome was assessed using the Japanese Orthopaedic Association (JOA) score, with evaluations conducted at baseline, one month, and three months. Recovery rates were also calculated. SPSS trial software version 27 (IBM Corp., Armonk, NY) was used for statistical analysis.

Results: Both groups exhibited improvement in JOA scores over time. At the one-month and three-month follow-ups, the mean JOA scores and recovery rates showed no statistically significant difference between the control and study groups (p-values > 0.05). Adverse effects related to antibiotic use were not significant.

Conclusion: The study concludes that the addition of antibiotics to the conventional treatment regimen for sacroiliitis does not provide significant benefit in terms of functional recovery or pain relief in patients non-responsive to NSAIDs and/or physical therapy. These findings underscore the importance of a targeted treatment approach based on the specific etiology of sacroiliitis and caution against unnecessary antibiotic use.
