Chlamydia Pneumoniae in the Etiology of the Keratoconjunctivitis Sicca in Adult Patients (a Pilot Study)
Abstract
In the pilot study the authors refer to the possible connection between the appearance of keratoconjunctivitis sicca (KCS) and Chlamydia pneumoniae (CP) infection. The decrease of the antibody levels was proved and objective findings and subjective symptoms of KCS in all patients subsided.
Altogether 7 patients were without clinical signs of the KCS and without regular application of local artificial tears treatment. At the same time, in two thirds of the patients, the levels of the antibodies decreased or remained unchanged.
In the last three patients, the signs of the dry eye decreased, but they didn't disappeared permanently. These patients had to apply artificial tears several times a day.
The suspect signs of this serologically active infection persisted despite the antibodies levels' decrease.
