Abstract:
Familial Mediterranean fever (FMF) is an ethnicity-specific autoinflammatory disease prevalent in the Arab world. It has various presentations including amyloidosis, small-vessel vasculitis, and pericarditis. Different mutations in the Mediterranean fever (MEFV) gene can cause this disorder and it is inherited in an autosomal recessive pattern. We present a case of a 23-year-old man of Iranian descent with history of periodic fever, diagnosed as Stanford type A aortic dissection secondary to an acute attack of FMF. To the best of our knowledge, this is the first case reported of such a complication. <Learning objective:1.Diagnosis of familial Mediterranean fever is a diagnosis of exclusion as many diseases involve large arteries and present with aortic involvement.2.Familial Mediterranean fever usually involves small- and medium-sized arteries but unusual case presentations can occur in some patients involving the aorta.3.Physicians in Pakistan must be made aware of the rapidly increasing prevalence of familial Mediterranean fever due to migration of susceptible ethnic groups in order to manage patients while they are still amenable to treatment.>.
Insights
Familial Mediterranean fever (FMF), an autoinflammatory disease, can rarely cause Stanford type A aortic dissection. This case highlights an unusual presentation of FMF in a young Iranian man.
Area of Science:
- Rheumatology and Genetics
- Cardiovascular Medicine
Background:
- Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disorder common in Arab populations.
- FMF typically presents with recurrent fever and serositis, but can also manifest as amyloidosis, vasculitis, or pericarditis.
- The Mediterranean fever (MEFV) gene mutations are causative for FMF.
Observation:
- A 23-year-old man of Iranian descent presented with periodic fever.
- He was diagnosed with Stanford type A aortic dissection during an acute FMF attack.
Findings:
- This case represents the first reported instance of Stanford type A aortic dissection as a complication of FMF.
- While FMF commonly affects small- and medium-sized arteries, this presentation involves the aorta, an unusual manifestation.
Implications:
- Physicians should consider FMF in the differential diagnosis of aortic involvement, especially in susceptible ethnic groups.
- Increased awareness of FMF prevalence, particularly in regions like Pakistan due to migration, is crucial for timely diagnosis and management.
- This case underscores the importance of recognizing atypical presentations of FMF to prevent severe complications.
