Ch. 21 - Arthropathies of IBD Flashcards
2 patterns of joint inflammation of IBD
1) Peripheral polyarthritis
2) Involvement of SI joints and axial skeleton
T/F: In IBD, arthralgia is more common than arthritis
T
Ratio of boys to girls in those with and without peripheral arthritis in IBD
Almost identical
T/F There is a pronounced tendency for familial clustering in UC and CD
T
T/F SI arthritis is more common in patients with IBD compared to the general population
T, >30x
Peripheral polyarthritis vs SI arthritis: Associated with HLA-B27
SI arthritis
Most frequently affected joint in IBD arthritis
Lower extremity joints, esp ankles and knees
Usual duration of peripheral arthritis in IBD
1-2 weeks, and tend to recur
Arthritis of IBD may last for months especially if
GI disease is active
T/F If joint inflammation in IBD lasts for months, permanent functional loss or joint damage ensues
F, permanent functional loss or joint damage is unusual
SI arthritis vs peripheral arthritis: May reflect activity and course of GI inflammation
Peripheral arthritis
SI arthritis vs peripheral arthritis: More common in IBD arthritis
Peripheral arthritis
T/F IBD arthritis may be accompanied by enthesitis
T, SI arthritis in particular
Very painful MSK complication of IBD that occurs symmetrically in the limbs, rather than the joints, and may be accompanied by increased sweating and purplish discoloration of the affected limbs
Hypertrophic osteoarthropathy
T/F Osteoporosis can take place in patients with IBD arthritis even without steroid use
T
Severe form of IBD that appears to be an autoinflammatory, and is associated with treatment-resistant colitis, perianal fistula formation, folliculitis, and arthritis
Infantile-onset IBD
Infantile onset IBD results from
Mutations in IL-10 or its receptor
Treatment for infantile-onset IBD that may be curative
Hematopoietic stem cell transplantation early in the course of disease
UC vs CD: Bloody diarrhea
UC
Perianal skin tags and fistulae
CD
T/F In IBD arthritis, GI symptoms usually precede joint disease by months or years
T
T/F: In IBD arthritis, joint symptoms may precede GI symptoms or intestinal disease
T
When arthritis precedes GI symptoms in IBD, arthritis resembles what chronic arthritides
JIA, JAS, or seronegative enthesopathy and arthropathy syndrome
T/F: Mucocutaneous manifestations of IBD are less common in patients who have arthritis compared to those without arthritis
F, more common especially in those with peripheral arthritis
