Hypothesis

Is a combination of intravenous clindamycin and oral tetracycline effective in treating active rheumatoid arthritis?

Conclusion

This antibiotic regime is unlikely to be a valuable therapy for active rheumatoid arthritis.

Supporting Evidence

  • Two patients in the active group achieved an ACR20 response, while none in the placebo group did.
  • There was a better ESR20 response in the placebo group.
  • The trial was halted after an interim analysis showed no significant differences.

Takeaway

Doctors tested a combination of two antibiotics to see if they could help people with rheumatoid arthritis, but it didn't seem to work.

Methodology

Patients with active RA were randomized to receive either the antibiotic treatment or a placebo for 25 weeks, with assessments made at regular intervals.

Potential Biases

Patients were aware of their treatment allocation, which could introduce bias.

Limitations

The trial was halted early due to lack of significant differences between treatment groups.

Participant Demographics

Patients aged 18 to 80 with active rheumatoid arthritis.
