[Cogan's syndrome with angitis of cranial nerves, aortitis, endocarditis, and glomerulonephritis (author's transl)]
Insights
Cogan's syndrome, a rare autoimmune disorder, can lead to severe aortic valve disease and heart failure. This case highlights the systemic vascular complications of Cogan's syndrome, impacting multiple organs.
Area of Science:
- Cardiovascular Medicine
- Rheumatology
- Ophthalmology
- Neurology
Background:
- Cogan's syndrome is a rare autoimmune disorder characterized by interstitial keratitis and vestibuloauditory dysfunction.
- Systemic involvement, particularly cardiovascular disease, is a known but less common manifestation.
- Pregnancy can be a trigger or exacerbate autoimmune conditions.
Observation:
- A 34-year-old woman presented with symptoms of Cogan's syndrome during pregnancy, including sensorineural hearing loss, vertigo, and vision loss.
- Three years later, she developed fatal left-heart failure.
- Necropsy revealed recurrent aortic valve endocarditis with stenosis and regurgitation, and severe aortitis.
Findings:
- The cause of death was left-heart failure secondary to combined aortic valve disease and thoracic aortitis.
- Aortitis and inflammation of the optic nerve and stato-acoustic nerve were responsible for the visual and vestibular deficits.
- Acute glomerulonephritis was also noted, potentially coincidental.
Implications:
- This case underscores the critical importance of monitoring for systemic vascular complications in patients with Cogan's syndrome, even during pregnancy.
- Early detection and management of aortitis and valvular disease are crucial to prevent severe cardiovascular events.
- Cogan's syndrome can have devastating multi-systemic consequences, necessitating a comprehensive diagnostic and therapeutic approach.
Abstract:
A 34-year-old woman died of left-heart failure due to combinated aortic-valve disease three years after manifestation of Cogan's syndrome characterized by sudden inner-ear deafness, loss of equilibrium, interstitial keratitis, and progressive loss of vision during pregnancy. At necropsy there was evidence of recurrent endocarditis of the aortic valves with stenosis and regurgitation, severe angitis of the thoracic aorta with marked secondary sclerosing changes as the cause of the heart failure. Angitis within the optical fasciculus and stato-acoustic nerve was the cause of the vestibular and optical defects. Primary changes in the visual and auditory cortices, the retina and inner ear were excluded as causes. There was also acute membrano-proliferative glomerulonephritis, which may have been coincidental.
