Clinical Predictors Associated with Severe Radiographic Sacroilitis in Axial Spondyloarthritis

Grace Yoon and colleagues presented a study to determine if there were clinical predictors of severe sacroilitis. They found association with non-Caucasian ethnicity, disease duration, a history of total hip arthroplasty, and more. Smoking tobacco as measured by pack is also a predictor of severe sacroilitis. With other conclusions the authors see a modifiable risk factor in smoking.
I think, we as rheumatologists or patients’ organisations should put even more emphasis on counseling patients to quit smoking and provide links or access to quit smoking programs.

Conclusion: Severe radiographic sacroilitis appears to be associated with predictable characteristics like disease duration and total hip arthroplasty, but also appears to be associated with less reported characteristics such as familial AS and tobacco use. Smoking may be a modifiable risk factor for the development of severe radiographic AS.

And here’s another study on the damage smoking is doing in ankylosing spondylitis.

Conclusion: Smoking, male sex, age and BASMI scores are independently associated with structural damage in AS. The association between the presence of calcaneal enthesophytes and syndesmophytes, which was present in univariate analysis but which disappeared after multivariate logistic regression analysis, needs to be further explored in future prospective studies.

And there’s still another study on the damage smoking is doing in ankylosing spondylitis.

Conclusion: The presence of radiographic damage in the spine (syndesmophytes), elevated acute phase reactants and cigarette smoking status predict spinal radiographic progression in early axial SpA.
