Systemic inflammatory cytokine profiles in patients with gout during flare, intercritical and treat-to-target phases: TNFSF14 as new biomarker

Ann Rheum DisPublished Mechanistic study

Authors' conclusion

Gout flare involves multiple inflammatory mediators that may be used as potential therapeutic targets.

Study context

Population
Prospective gout population (GOUTROS); validation in an independent cohort (OLT1177–05)
Comparison
Plasma inflammatory proteins at gout flare (T1) vs intercritical phase (T2) vs serum urate target under ULT (T3)
Outcome
Levels of 92 inflammation-related plasma proteins across gout phases
Methodological detailsprospective cohort, targeted proteomics (Olink), independent validation cohort, ex vivo and in vitro experiments
  • Prospective cohort
  • Targeted proteomics (Olink)
  • Independent validation cohort
  • Ex vivo and in vitro experiments

Main finding

As reported in the abstract

21

IL-6, colony-stimulating factor 1, vascular endothelial growth factor A and TNFSF14 increased during gout flare in an independent cohort
