Objective Patients with axial spondyloarthritis (axSpA) in clinical remission tapered tumor necrosis factor inhibitor (TNFi) therapy according to a clinical guideline. Over a 2-year follow-up period, we aimed to investigate flare frequency, dose at which flare occurred, type of flare, and predictors thereof. Methods Patients in clinical remission (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] < 40, physician global score < 40, and without disease activity the previous year) tapered TNFi to two-thirds the standard dose at baseline, half at week 16, one-third at week 32, and discontinued at week 48. Flares were defined as BASDAI flare (BASDAI ≥ 40 and change ≥ 20 since inclusion), and/or clinical flare (development of inflammatory back pain, musculoskeletal or extraarticular manifestations, and/or Ankylosing Spondylitis Disease Activity Score [ASDAS] ≥ 0.9), and/or magnetic resonance imaging (MRI) flare (≥ 2 new or worsened inflammatory lesions). Results Of 108 patients, 106 (99%) flared before 2-year follow-up: 29 patients (27%) at two-thirds standard dose, 21 (20%) at half dose, 29 (27%) at one-third dose, and 27 (25%) after discontinuation. Regarding type of flare, 105 (99%) had clinical flares, 25 (24%) had BASDAI flares, and 23 (29% of patients with MRI at flare available) had MRI flares. Forty-one patients (41%) fulfilled the Assessment of SpondyloArthritis international Society (ASAS) definition of clinically important worsening (≥ 0.9 increase since baseline). Higher baseline physician global score was an independent predictor of flare after tapering to two-thirds (OR 1.19, 95% CI 1.04-1.41, P = 0.01). Changes in clinical and/or imaging variables in the 16 weeks prior to tapering did not predict flare. Conclusion Almost all (99%) patients with axSpA in clinical remission experienced flare during tapering to discontinuation, but in over half of these patients, flare did not occur before receiving one-third dose or, Objective.

Objectives In a 2-year follow-up study of patients with axial spondyloarthritis (axSpA) in clinical remission who tapered TNF inhibitor (TNFi) treatment according to a clinical guideline, we aimed to investigate the proportion who successfully tapered/discontinued therapy and baseline predictors thereof. The proportion regaining clinical remission after flare and the progression on MRI/radiography were also assessed. Methods One-hundred-and-nine patients (78 [72%]/31 [28%] receiving standard and reduced dose, respectively) in clinical remission (BASDAI < 40, physician global score < 40) and no signs of disease activity the previous year tapered TNFi as follows: to two-thirds of standard dose at baseline, half at week 16, one-third at week 32 and discontinuation at week 48. Patients experiencing clinical, BASDAI or MRI flare (predefined criteria) stopped tapering and escalated to previous dose. Prediction analyses were performed by multivariable regression. Results One hundred and six patients (97%) completed 2 years' follow-up; 55 patients (52%) had successfully tapered: 23 (22%) receiving two-thirds, 15 (14%) half, 16 (15%) one-third dose and 1 (1%) discontinued. In patients at standard dose at baseline (n = 78), lower physician global score was the only independent predictor of successful tapering (odds ratio [OR] = 0.79 [95% CI: 0.64, 0.93]; P = 0.003). In the entire patient group lower physician global score (OR = 0.86 [0.75, 0.98]; P = 0.017), lower Spondyloarthritis Research Consortium of Canada (SPARCC) Sacroiliac Joint Erosion score (OR = 0.78 [0.57, 0.98]; P = 0.029) and current smoker (OR = 3.28 [1.15, 10.57]; P = 0.026) were independent predictors of successful tapering. At 2 years, 97% of patients were in clinical remission. Minimal changes in imaging findings were observed. Conclusion After 2 years following a clinical guideline, 52% of patients with axSpA in clinical remission had successfully tapered TNFi, only 1% discontinued. Baseline physi

OBJECTIVES: To study prospectively whether structural changes determined by ultrasound scanning (US) can be used as prognostic markers for outcome in patients with symptomatic Achilles tendinopathy (AT) and to investigate whether there exists an association between US findings and pain measured by visual analog scale (VAS) and a general assessment score (GA).METHODS: 92 consecutive patients with AT symptoms were recruited from two outpatient clinics in rheumatology. The patients underwent a conservative treatment protocol consisting of reduced activities, controlled rehabilitation including eccentric exercises of the calf muscles and if needed supplemented with corticosteroid injections. The patients were examined clinically and by US (tendon thickness, hyper- and hypoechogenicity, calcification, bursitis, calcaneusspure, tenosynovitis, gray scale and color Doppler focusing on increased flow intra- or peritendinous). The clinical and US examination were performed at entry, 1, 2, 3 and at 6 month.RESULTS: 42 women and 50 men were included (mean age of 47 years). They had symptoms for more than 13 months and a symptomatic Achilles tendon mean thickness of 7.4±2.3mm. Heterogeneity at the initial examination was found to be a prognostic marker for the clinical outcome. Tendon thickness, hypoechogenicity and increased flow at any time point were significantly correlated to pain at function, palpatory pain and morning pain at the same time points. A reduction in tendon thickness was statistically associated with a decrease in palpatory pain.CONCLUSION: Heterogeneity is a prognostic marker in AT. Tendon thickness, hypoechogenicity and increased Doppler activity can be used as objective outcome parameters for the treatment effect of AT.
