Residual activated Th17 cells during low disease activity are associated with disease worsening in radiographic axial spondyloarthritis: A pilot study

Joint Bone SpinePublished Prospective cohort study

Authors' conclusion

Residual activated Th17 cells during inactive disease or LDA are associated with subsequent disease worsening in r-axSpA.

Study context

Population
Patients with radiographic axial spondyloarthritis (r-axSpA) in inactive disease or low disease activity (LDA) (ASDAS<2.1)
Participants

  • Activated Th17-highn = 9
  • Activated Th17-lown = 12reference
Outcome
ASDAS trajectory and loss of LDA (ASDAS≥2.1)
Follow-up
6 months
Methodological detailspilot study, ROC-derived cut-off, linear mixed-effects models
  • Pilot study
  • ROC-derived cut-off
  • Linear mixed-effects models

Main finding

As reported in the abstract

Loss of LDA (ASDAS≥2.1)

Activated Th17-high

44.4%

4 of 9

Activated Th17-low

0

events

P < 0.05

Significantly worse ASDAS trajectory during follow-up in activated Th17-high vs activated Th17-low
P for interaction < 0.05

Observational data: associations, not effects.

Further findings

Baseline disease activity status (inactive disease [ASDAS<1.3] vs LDA [1.3≤ASDAS<2.1])

Not associated with differences in ASDAS trajectories
P for interaction = non-significant
Not associated with loss of LDA
P = non-significant
