We have previously reported the association of Chlamydia trachomatis with HLA B27+ related diseases. To investigate the possibility that chlamydial antibodies serve to localize the immune response in such diseases, we examined the crossreactivity of chlamydial antibodies (rabbit anti-D and anti-L2 serotypes) with peripheral blood mononuclear cells of patients with ankylosing spondylitis (AS) and anterior uveitis (AU) and with human and bovine ocular tissue and cells in culture. Our results indicate a significantly increased percentage binding of chlamydial antibody (D serotype) to the mononuclear cells of HLA B27+ patients with AS when compared with HLA B27- patients with AS (12.9% +/- 2.2 versus 5.4% +/- 2.2), B27+ controls (5.5% +/- 1.5) and B27- controls (6.1% +/- 1.0). There was no significant difference between controls and HLA B27+ patients with AU (6.6% +/- 1.9) and B27- patients with AU (8.7% +/- 1.1). This crossreactivity could not be blocked by monoclonal HLA B27 antibody. Chlamydial antibodies (D and L2) crossreact with human and bovine conjunctiva but not uvea, tissue culture derived iris fibroblasts or smooth muscle cells. Our results provide additional support for the concept of crossreactivity between antibodies to microbial agents and peripheral blood mononuclear cells of patients with HLA B27+ AS.

Systemic diseases as rheumatoid arthritis and ankylosing spondylitis have unknown etiologies, unclear pathogenic mechanisms and multiorgan involvements. Ocular involvement is variable and may effect several levels: sclera, cornea, uvea and conjunctiva. Because an ocular event signify an enhancement of inflammatory-immune reactions, the patient may undergo a complete investigation and general therapy must complete local treatment. The paper showing the ocular manifestation in patients with rheumatic arthritis through a ten-years period.
