Spondyloarthritis & psoriatic arthritis
Clinical and laboratory factors associated with the bamboo spine in patients with axial spondyloarthritis: are there clues for the bamboo spine?
Authors' conclusion
Bamboo spine was more common in the male sex and associated with a delay in diagnosis, high BMI, hip involvement, and enthesitis.
Study context

- Exposure
- Bamboo spine vs longstanding disease without syndesmophytes
- Group 1n = 111
- Outcome
- Clinical and laboratory factors associated with bamboo spine
Methodological detailsnational, multicentre, longitudinal, observational database (TReasure), multivariate logistic regression

Median
| Outcome | Group 1 | Group 2 | P value |
|---|---|---|---|
| BMI | 27.7 (range as printed 25.8–31.1) | 25.9 (range as printed 22.9–29.2) | P < 0.001 |
Enthesitis

Male sex
- Male sex more common among patients with bamboo spine
HLA-B27 status
- Did not differ between groups
Smoking
- More prevalent in Group 1
Multivariate logistic regression
