Area of Science:

  • Immunology
  • Rheumatology
  • Genetics

Background:

  • Familial Mediterranean fever (FMF) is an autoinflammatory disease.
  • Immune reactions play a key role in FMF pathogenesis.
  • Complement system activation is implicated in FMF.

Purpose of the Study:

  • To investigate complement system activity in FMF patients.
  • To assess the impact of colchicine therapy on complement components.
  • To explore the role of immune reactions in FMF.

Main Methods:

  • Hemolytic assay used to measure total hemolytic activity of complement (THAC).
  • Activities of individual complement components (C1, C2, C3, C4) were determined.
  • FMF patients were categorized based on colchicine treatment regularity.

Main Results:

  • No significant differences in C1, C2, C3, and C4 hemolytic activities were observed.
  • FMF patients receiving regular colchicine treatment showed normal complement component activity.
  • Comparison between healthy subjects and FMF patients on regular colchicine revealed no significant changes.

Conclusions:

  • Regular colchicine treatment appears to normalize complement component activity in FMF patients.
  • The findings raise questions about FMF pathogenesis and complement's role.
  • The study reaffirms the efficacy of consistent colchicine therapy for FMF.
