enthesitis


Also found in: Wikipedia.

en·the·si·tis

(en-thĕ-sī'tis),
Condition occurring at the insertion of muscles where recurring concentration of muscle stress provokes inflammation with a strong tendency toward fibrosis and calcification.
[G. enthetos, implanted, + -itis, inflammation]

enthesitis

[en′thəsī′tis]
an inflammation of the insertion of a muscle with a strong tendency toward fibrosis and calcification. It is usually only painful when the involved muscle is activated.

en·the·si·tis

(en'thĕ-sī'tis)
Traumatic disease occurring at the insertion of muscles where recurring concentration of stress provokes inflammation with a strong tendency toward fibrosis and calcification.
[G. enthetos, implanted, + -itis, inflammation]

enthesiopathy

; enthesitis acute or chronic inflammation at insertion of tendon or ligament into periosteum and underlying bone, characterized by local pain and/or swelling, and possible spur formation; complication of plantar fasciitis; typical of anykylosing spondylitis and other sero-negative arthropathies (see Table 1)
Table 1: Common features of the range of types of sero-negative inflammatory arthritis
FeatureComment
Leukocyte antigen type90% of patients with sero-negative arthritis test positive for human leukocyte antigen (HLA) B27
Skeletal involvementAxial skeleton/spinal involvement; with back pain (common presenting first symptom)
EnthesopathyInflammation at insertions of ligaments/tendons (posterior calcaneum, plantar calcaneum, base of fifth metatarsal, forefoot)
Soft-tissue swellingsLocalized swelling at Achilles tendon insertion
Bursitis of congenital/adventitious bursae
SynovitisDactylitis/'sausage' toe
Generalized swelling of fore foot
VasculitisNote: Does not tend to affect foot in sero-negative arthritides
RadiographsBone/periosteal fluffy/'whiskery' proliferation
New bone/spur formation at entheses, secondary to inflammation

enthesitis (en·th·siˑ·tis),

n condition characterized by recurring, concentrated stress at points of muscle insertion that leads to inflammation and possible calcification and fibrosis.

The use of the CDAI means that disease features of PsA such as enthesitis, psoriasis, and dactylitis were not captured in the assessment of LDA.
Enthesitis-Related Arthritis (ERA) is a subtype that has replaced, but is not exactly overlapping with, previous definitions in children such as juvenile ankylosing spondylitis or syndrome of seronegative enthesitis arthritis.
sup][35] A research in 2014 applied quantitative CEUS to the evaluation of enthesitis of SpA.
Another important clinical feature of PsA is enthesitis frequently affecting the Achilles tendon.

It comes in the differential diagnosis of seronegative rheumatoid arthritis (RA), Reiter's disease, ankylosing spondylitis with enthesitis and inflammatory bowel disease associated arthritis.
The presentation of the clinical phenotype of AS patients was as follows: 51 (100%) patients were diagnosed with sacroiliitis and enthesitis, 17 (33.
Symptoms include joint pain and stiffness, skin and nail psoriasis, swollen toes and fingers and persistent painful enthesitis (inflammation of the sites where tendons or ligaments insert into the bone).
Inflammatory back pain (IBP) and enthesitis are hallmarks of this family of disorders that can affect both axial and peripheral joints.
In terms of PsA treatment approaches, an evidence review that he and his associates in GRAPPA published in 2009 found that biologies (anti-tumor necrosis factor inhibitors) as a group were effective in all five domains of the disease: peripheral arthritis, skin and nail disease, axial disease, dactylitis, and enthesitis, while the oral disease-modifying antirheumatic drugs (DMARDs) were effective for peripheral arthritis and skin and nail disease.
The resulting arthritis is characterised by asymmetrical arthritis, usually in the lower limbs, inflammatory eye disease, enthesitis (inflammation of tendons and ligaments at their insertions into bones), dactylitis (painful inflammation of fingers or toes), spondylitis (inflammation of the vertebrae) and sacroiliitis.
HLA-DR17 is associated with enthesitis in psoriatic arthritis.
