TNRSF1A-pR92Q variant identifies a subset of patients more similar to systemic undifferentiated recurrent fever than TNF receptor-associated periodic syndrome

Clin Exp RheumatolPublished Retrospective registry-based cohort study

Authors' conclusion

Patients with AID carrying the TNFRSF1A-pR92Q variant behave more like SURF patients and differ from patients diagnosed with classical TRAPS and PFAPA in clinical phenotype.

Study context

Population
Autoinflammatory disease (AID) patients from the Eurofever international multicentre registry
Participants
361 patients
Exposure
pR92Q variant AID vs classical TRAPS, PFAPA and syndrome of undefined recurrent fever (SURF)
  • pR92Qn = 77reference
  • Classical TRAPSn = 72
  • PFAPAn = 152
  • SURFn = 60

Main finding

As reported in the abstract

  • pR92Q carriers had an older age of disease onset than classical TRAPS and PFAPA
  • Classical TRAPS had more relatives affected and were more likely to have migratory rash and AA-amyloidosis than pR92Q
  • Part of pR92Q patients had PFAPA-like symptoms, despite several differences vs PFAPA
  • pR92Q and SURF showed a comparable clinical phenotype
  • No major differences in response to treatment between the four groups
  • Steroids most often prescribed and effective in the majority

Observational data: associations, not effects.
