Sjögren's disease & overlap diseases

Concomitant Sjögren’s disease in patients with neuromyelitis optica spectrum disorder (NMOSD): impacts on neurologic disease severity and recurrence

Arthritis Res TherPublished Cross-sectional study

Authors' conclusion

NMOSD patients with SjD manifested more severe disease at attack and relapsed earlier than those without SjD.

Study context

Population
NMOSD patients serologically positive for AQP4-IgG, single tertiary centrederivation 108, validation 47
Participants
155 participants
Exposure
NMOSD with Sjogren's disease (SjD) vs NMOSD without SjD
  • NMOSD with SjDn = 70
  • NMOSD without SjDn = 85reference
Outcome
Predictors of coexisting SjD and performance of a predictive nomogram
Methodological detailssingle tertiary-centre cohort, predictive nomogram, derivation and validation groups (7:3), logistic regression
  • Single tertiary-centre cohort
  • Predictive nomogram
  • Derivation and validation groups (7:3)
  • Logistic regression

Observational data: associations, not effects.

Further findings

Relapse and time to EDSS score 4.0 (survival curve analysis)

EDSS score in NMOSD with SjD associated with clinical relapse; reached EDSS 4.0 earlier than those without SjD
