Abstract:
Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by recurrent and self-limited attacks of serosal inflammation with abdominal pain, chest pain, and arthritis usually accompanied by fever. Different vasculitides such as polyarteritis nodosa (PAN) and Henoch-Schönlein syndrome (HSS) may be associated with FMF. We report two sisters of a Turkish family with FMF who developed distinct vasculitides. The younger sister developed severe PAN with perirenal hematoma at the age of 13 years, the older sister presented with severe HSS and acute renal failure at the age of 19 years. Neither sister developed amyloidosis until the age of 30 years. This observation suggests that early events in the pathogenesis of PAN and HSS are generally quite similar.
Insights
Familial Mediterranean fever (FMF) can be associated with vasculitis. Two sisters with FMF developed distinct vasculitides, polyarteritis nodosa (PAN) and Henoch-Schönlein syndrome (HSS), suggesting similar early disease pathways.
Area of Science:
- Rheumatology
- Genetics
- Internal Medicine
Background:
- Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disorder.
- FMF presents with recurrent serosal inflammation, fever, and pain.
- Associated vasculitides like polyarteritis nodosa (PAN) and Henoch-Schönlein syndrome (HSS) can occur in FMF patients.
Observation:
- This report details two sisters from a Turkish family diagnosed with FMF.
- The younger sister developed severe PAN with perirenal hematoma at age 13.
- The older sister presented with severe HSS and acute renal failure at age 19.
Findings:
- Both sisters developed distinct vasculitic syndromes.
- Neither sister developed amyloidosis by age 30.
- The distinct vasculitic presentations in FMF patients were noted.
Implications:
- This case series suggests early pathogenic similarities between PAN and HSS in the context of FMF.
- Understanding these shared pathways may inform future FMF and vasculitis research.
- Further investigation into the early pathogenesis of FMF-associated vasculitides is warranted.
