We describe a patient with relapsing polgchondritis in whom aortic valve inflammation developed 3 years after diagnosis, when the polychondritis had been in apparent remission for an extended period of time. Infection and cardiac involvement can be significant complications of relapsing polychondritis. Recommendations for monitoring and treatment of patients with this disease are discussed.Relapsing polychondritis is a systemic autoimmune disease characterized by episodic inflammation of cartilaginous structures (nose, ear, and trachea). It is associated with inflammatory arthritis and occasionally with vasculitis, aortitis, and inflammation of the aortic valve and ring. We report a case of relapsing polychondritis in which aortic valve involvement developed 3 years after diagnosis, when the patient was otherwise asymptomatic, had not been receiving therapy for 7 months, and had a normal erythrocyte sedimentation rate (ESR).
CASE REPORTThe patient was well until April 1985 when, at the age of 35, he developed chronic otitis media which did not respond to antibiotic treatment. Over the ensuing 4 months he developed iridocyclitis, cough and hemoptysis, fatigue, myalgias, and arthralgias. In October he noted the onset of erythema and tenderness of the bridge of the nose and external otitis media, which resolved without treatment.On presentation to us 4 weeks later, his physical examination findings were notable only for costochondritis and swelling of the second proximal interphalangeal joint of the left hand. Cardiac examination revealed the absence of murmurs. Urinalysis results, creatinine levels, and chest radiography findings were within normal limits. The ESR (Westergren) was 94 mm/hour, and antinuclear antibodies were present at a titer of 1 : 160. Assays for anticollagen antibodies, rheumatoid factor, and complement levels all yie!ded normal results.Relapsing polychondritis was diagnosed and the patient was begun on a regimen of prednisone, 50 mg/day. He responded well with resolution of symptoms, and the prednisone was tapered over 2 years, and then discontinued. During this time he developed occasional worsening of the iridocyclitis and joint pain, but had no further episodes of inflammation of the nasal or ear cartilage.The patient had been asymptomatic and not receiving treatment for 7 months when he returned for followup. Examination findings at that time were remarkable for a III/VI systolic and diastolic murmur at the left sternal border (second intercostal space), which radiated to the carotid artery. Echocardiography revealed aortic regurgitation. The ESR was 16 mmhour. He felt well and continued to participate in competitive soccer.However, a followup echocardiogram 6 months later showed progressive aortic regurgitation and left
