Implications of serum calcitonin gene-related peptide and type I interferon in systemic lupus erythematosus-associated headaches

LupusPublished Cross-sectional study

Authors' conclusion

Serum CGRP and type I IFNs levels may not be involved in SLE-associated headaches.

Study context

Population
Patients with systemic lupus erythematosus (SLE) from a Japanese multicenter cohort and a biobankplus 20 healthy controls (HC)
Participants
144 patients
Exposure
SLE with headache vs SLE without headache vs healthy controls
  • Headachen = 60
  • HCn = 20reference
Outcome
Serum CGRP, IFN-α and IFN-β levels (enzyme-linked immunoassay) as headache biomarkers
Methodological detailsmulticentre cohort and biobank
  • Multicentre cohort and biobank

Main finding

As reported in the abstract

Serum CGRP, IFN-α and IFN-β levels
  • Serum calcitonin gene-related peptide (CGRP) and interferon (IFN)-α levels not significantly different between patients with headache, those without headache, and HC
  • Headache vs Without headache: P < 0.005
  • Headache vs HC: P < 0.005
  • Without headache vs HC: P < 0.005

Observational data: associations, not effects.
