The prevalence of axial spondylarthropathy (SpA) and (ankylosing spondylitis) AS in IBD patients late in the disease course was higher than the prevalence reported in general populations.
The prevalence of chronic nonspecific back pain amongst IBD patients was comparable to that reported in the general population.
Why this matters
Patients with IBD often suffer from extraintestinal rheumatic manifestations, prevalently including inflammatory back disorders like ankylosing spondylitis (AS), axial spondylarthropathy (axial SpA) and inflammatory back pain (IBP).
But few studies have estimated the prevalence of these disorders late in the disease course.
Of the total 599 patients from the original cohort still living, 470 (78.5%) were investigated.
Chronic back pain had been present during the disease course in 148 patients (31.5%), 90 (38.3%) women and 58 (24.7%) men.
The ASAS criteria for IBP were met by 37 patients (7.9%), 23 women and 14 men, and 17 patients (3.6%) fulfilled the criteria for axial SpA (11 women and 6 men).
Over the last three months, 80 patients (17.0%) reported chronic back pain, leaving only 21 patients (4.5%) fulfilling the IBP criteria and five patients (1.1%) the axial SpA criteria.
AS was diagnosed in 21 patients (4.5%), 8 women and 13 men; the total HLA-B27 prevalence was 8.7%, higher among patients with chronic...
