Summary
The Rome and New York criteria for ankylosing spondylitis (AS) were compared. The Rome criterion for low back pain was the best clinical discriminator, while radiographic criteria performed well, suggesting a need for new population survey criteria.
Area of Science:
- Rheumatology
- Orthopedics
- Clinical Diagnostics
Background:
- Ankylosing spondylitis (AS) diagnosis relies on established criteria.
- Comparing the efficacy of Rome and New York criteria is crucial for diagnostic accuracy.
Purpose of the Study:
- To compare the diagnostic performance of the Rome and New York criteria for ankylosing spondylitis (AS).
- To evaluate clinical and radiographic discriminators for AS diagnosis.
Main Methods:
- A clinical sample of patients with AS and other joint disorders was assessed.
- Individual clinical and radiographic criteria from Rome and New York were evaluated for their discriminatory power.
Main Results:
- The Rome criterion for low back pain (lasting three months) was the strongest individual clinical discriminator.
- The New York criterion for lumbar spine limitation in three planes outperformed its Rome counterpart.
- Both sets of radiographic criteria demonstrated good performance in discriminating AS.
Conclusions:
- Existing criteria have limitations, particularly for population surveys, necessitating the development of new diagnostic standards.
- Peripheral joint involvement does not appear to be a significant factor for revising current AS diagnostic criteria.
