Isolation of Chlamydia psittaci from a patient with interstitial keratitis and uveitis associated with otological and cardiovascular lesions.

Diagnostic Difficulties of Cogan Syndrome

“…There is some data in the literature concerning a link between CS and chronic chlamydial infection [2]. Long-term contact with pigeons, along with positive serology against Chlamydia psittaci, suggests chronic infection as a trigger for a CS in this case.…”

“…Vasculitic manifestations include mainly arteritis affecting small, medium or large arteries and according to the International Chapel Hill Consensus Conference Nomenclature of Vasculitides, CS is defined as "variable vessel vasculitis" [1]. The onset of the disease is preceded in approximately 20% of cases by an infection, especially Chlamydia psittaci [2] and Chlamydia trachomatis [3]. Recent evidence strongly suggests that CS is an autoimmune disease that is mediated by a hypersensitive response to infectious agents associated with vasculitis [3][4][5].…”

Chlamydial infections of the heart

“…As in other chlamydial infections, the clinical course may be acute, subacute or indolent (6,49,50). The aortic valve was involved in most cases (6,36,50,54,55,57,59). The mortality rate was high (50,54,55), and in many cases valve replacement was needed (36, 49,50,54).…”

Sudden bilateral deafness and Chlamydophila infection

“…Finally, Darougar et al reported the case of a 15‐year‐old girl who presented with chronic relapsing sensorineural hearing loss, uveitis, keratitis and vertigo 4 . In this case, chlamydial antibody titres were raised, and C. psittaci was isolated from the conjunctiva.…”
