4.  Extra-articular manifestations and comorbidities

•  The frequently observed extra-articular manifestations, for example, psoriasis, uveitis and IBD, should be managed in collaboration with the respective specialists.

•  Rheumatologists should be aware of the increased risk of cardiovascular disease and osteoporosis.

Cardiovascular comorbidities

Risk of myocardial infarction and stroke in AS •  A systematic literature review with 8 longitudinal studies.

•  AS (n=3,279): 224 MI cases (incidence 7.4%; 95%CI 5.2%, 10.0%).

•  Controls (n=82,745): 1318 MI cases (incidence 4.6%; 95%CI 1.2%, 10.0%).

•  Risk ratio for MI 1.88 (95% CI 0.83, 4.28).

•  No risk increase for stroke, but higher weighted mean intima-media thickness and higher risk of metabolic syndrome.

•  Lipid profile in AS: a significant decrease in triglycerides, total cholesterol, and high-density lipoprotein (HDL).

Prevalence of vertebral fractures in AS

Klingberg E, et al. J Rheumatol 2012;39:1987-95.

The majority of fractures were subclinical. Factors significantly associated with fractures: •  lower BMD, •  higher age and longer disease duration, •  impaired mobility, •  syndesmophyte formation, •  smoking.

Osteoporosis: summary •  Patients with ankylosing spondylitis are at risk for osteoporosis and

osteoporotic vertebral fractures.

•  Significant bone loss might occur even early in the course of the disease.

•  In patients with long-standing AS, a BMD measurement in the hip neck might provide more reliable results in comparison to lumbar spine.

•  Risk of osteoporosis and fractures is increased in patients with high inflammatory activity, long-standing disease, presence of syndesmophytes and limited spinal mobility and in smokers. Psoriasis and IBD are also associated with higher risk for osteoporosis.

•  Whether antiosteoporotic treatment initiated early might improve the long-term outcome is unclear.
