Characteristics of Post-traumatic-spondyloarthritis: A Cross-sectional Study From a Single Tertiary Hospital.

Objective: Trauma has been proposed as a triggering factor of psoriatic arthritis (PsA), and the deep Koebner phenomenon was the suggested underlying mechanism The relationship between spondyloarthritis (SpA) and trauma was only observed in PsA This study investigated cases of SpA other than PsA that occurred after physical trauma and analyzed their clinical, laboratory, and radiologic features.

Methods: We retrospectively reviewed the medical records of 213 patients who visited our hospital due to a suspicion of SpA and grouped them into post-traumatic-SpA (PT-SpA, n=12) and non-post-traumatic-SpA (non-PT-SpA, n=201) Baseline characteristics were compared between the two groups by cross-sectional manner.

Results: Peripheral SpA was more common in PT-SpA than in non-PT-SpA Active inflammation on sacroiliac joint (SIJ) magnetic resonance imaging (MRI) was more common in non-PT-SpA (835% vs 545%, p=0046) The modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) was significantly higher in the non-PT-SpA group (20 vs 00, p=0007) Symptom duration from the first SpA symptom to diagnosis tends to be longer in the non-PT-SpA group (20 vs 05 years, p=0079).

Pilot study: asymptomatic hyperuricemia patients with obesity and nonalcoholic fatty liver disease have increased risk of double contour sign.

Background/aims: Double contour sign (DCS) is a representative ultrasonographic finding in gout. DCS is evidence of monosodium urate deposit in gouty arthritis and has been identified in some patients with asymptomatic hyperuricemia. However, the specific characteristics of asymptomatic hyperuricemia in patients with DCS have not yet been revealed.

Baseline severity of sacroiliitis can predict acute inflammatory status of sacroiliac joint in early axial spondyloarthritis of male patients: a cross sectional study.

Background: This study compared clinical, laboratory and radiographic features of axial spondyloarthritis (axSpA) between ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nrAxSpA) of young male patients. Additionally, we sought factors which can predict the baseline inflammatory status of sacroiliac joint (SIJ) in axSpA.

Methods: We retrospectively reviewed the medical records of 322 patients who visited our hospital due to inflammatory back pain, and 159 male patients with axSpA were enrolled.
