Lupus & antiphospholipid syndrome

Validating treat-to-target endpoints in childhood lupus: data-driven sensitivity analyses from the UK JSLE cohort study

Rheumatology (Oxford)Published Cohort study

Authors' conclusion

Refining the cLLDAS definition by lowering the SLEDAI-2K cut-off to ≤3 and PGA to ≤0.25 may enhance protection against moderate-severe flare, but not new damage. No variations of cCR or cCR-0 showed significant improvement.

Study context

Population
Childhood-onset SLE, UK JSLE Cohort Study
Exposure
Varied vs original consensus-derived cSLE treat-to-target definitions
Outcome
Hazards of subsequent moderate-severe flare and new damage
Methodological detailsdata-driven sensitivity analyses, Prentice-Williams-Peterson (PWP) gap-time models, two-sided t-tests comparing hazard ratios (HRs)

Main finding

As reported in the abstract

Moderate-severe flare (attainment of varied cLLDAS)
Each group vs original targetsHazard ratio (CI)P value
cLLDAS SLEDAI-2K ≤3
0.13(0.09–0.19)
P < 0.001
cLLDAS PGA ≤0.25
0.14(0.10–0.20)
P < 0.001
Modified cLLDAS
0.12(0.08–0.17)
P < 0.001

Observational data: associations, not effects.

Further findings

New damage (Childhood Lupus Low Disease Activity State (cLLDAS) variations)

These variations in cLLDAS did not impact on the hazards of new damage

Moderate-severe flare/new damage (cCR and cCR-0 variations)

No variations of cCR and cCR-0 led to a significant improvement
all P > 0.05
