Articular damage in familial Mediterranean fever. Report of four cases
Abstract:
Four cases of familial Mediterranean fever have been reported in which the disease produced organic damage to a joint. The diagnosis was confirmed by clinical and family history and a typical course which included attacks of recurrent joint synovitis. The laboratory findings, while typical, were not specific. The main involvement was in the lower limbs. The findings at operation were of a non-specific synovitis with destruction of cartilage. It is emphasized that in the majority of cases of familial Mediterranean fever the joint involvement is transient and only uncommonly does damage to the joint become permanent. The fact that organic joint damage occurs is not widely recognized, which is the reason for our report of these four cases.
Insights
Familial Mediterranean fever can cause permanent joint damage, not just temporary inflammation. This report highlights four cases of organic joint damage in patients with this condition.
Area of Science:
- Rheumatology
- Genetics
- Internal Medicine
Background:
- Familial Mediterranean fever (FMF) is an autoinflammatory disorder.
- Joint involvement in FMF is typically transient synovitis.
- Organic joint damage in FMF is underrecognized.
Purpose of the Study:
- To report four cases of FMF with permanent organic joint damage.
- To increase awareness of this uncommon complication of FMF.
Main Methods:
- Clinical diagnosis of FMF based on history and recurrent synovitis.
- Family history assessment.
- Surgical findings including synovitis and cartilage destruction.
Main Results:
- Four patients with FMF presented with significant joint damage.
- Lower limb joints were primarily affected.
- Surgical findings revealed non-specific synovitis and cartilage destruction.
Conclusions:
- Familial Mediterranean fever can lead to permanent organic joint damage.
- This complication, though uncommon, should be recognized in FMF patients.
- Early recognition and management may prevent long-term joint sequelae.
