Pulmonary amyloidosis in familial Mediterranean fever

Abstract:
Familial Mediterranean Fever (FMF) is a hereditary periodic fever syndrome expressed by acute episodes of fever and painful manifestations. The gravest consequence of FMF is kidney involvement by secondary amyloidosis of AA type, which gradually leads to nephrotic syndrome and uremia. Nephropathic amyloidosis of the AA type, which complicates FMF in most untreated patients, may progress to effect other organs, including the lungs. This kind of organ involvement rarely produces noticeable symptoms and is associated with symptomatic involvement of other organs while remaining subclinical in itself. In this report, one case who had nephropathic and pulmonary amyloidosis of the secondary amyloidosis of AA type, wich complicates the FMF was presented and the pulmonary manifestations of FMF were reviewed.
Insights
Familial Mediterranean Fever (FMF) can lead to AA amyloidosis affecting kidneys and lungs. This case highlights rare pulmonary involvement in FMF patients with nephropathic AA amyloidosis.
Area of Science:
- Nephrology
- Pulmonology
- Genetics
Background:
- Familial Mediterranean Fever (FMF) is an inherited autoinflammatory disorder characterized by recurrent fever and inflammation.
- AA amyloidosis, a complication of chronic inflammation, can affect organs like the kidneys and lungs.
Observation:
- This report details a case of FMF with concurrent nephropathic and pulmonary AA amyloidosis.
- Pulmonary involvement in AA amyloidosis secondary to FMF is often subclinical, presenting alongside symptomatic organ damage.
Findings:
- The case illustrates the progression of AA amyloidosis from nephropathy to pulmonary complications in an FMF patient.
- Review of FMF pulmonary manifestations indicates they are typically asymptomatic and detected incidentally.
Implications:
- Understanding the spectrum of AA amyloidosis in FMF is crucial for early diagnosis and management.
- Recognizing subclinical pulmonary involvement may improve prognostication and treatment strategies for FMF patients.
