Ocular inflammation associated with Yersinia infection

Area of Science:

• Ophthalmology
• Rheumatology
• Infectious Diseases

Background:

• Yersinia infections are known to cause reactive arthritis.
• Ocular manifestations associated with Yersinia infection require further characterization.

Purpose of the Study:

• To investigate the clinical characteristics of ocular inflammation in patients with Yersinia infection.
• To determine the association between Yersinia infection, HLA-B27, and ocular and rheumatic conditions.

Main Methods:

• Retrospective study of 23 patients with Yersinia infection.
• Clinical examination and laboratory tests including HLA-B27 typing.
• Ophthalmological assessment of anterior uveitis and conjunctivitis.

Main Results:

• High incidence of arthritis (22/23) and ocular inflammation (17/23 acute anterior uveitis, 9/23 conjunctivitis) post-infection.
• All patients with ocular inflammation tested positive for HLA-B27 antigen.
• Acute anterior uveitis presented with characteristic inflammatory signs and responded to corticosteroids, with recurrences in half of the cases.

Conclusions:

• Yersinia infection can precipitate acute anterior uveitis and conjunctivitis in HLA-B27 positive individuals.
• Ocular inflammation associated with Yersinia infection frequently coexists with rheumatic manifestations.
• Early diagnosis and management of ocular inflammation are crucial in patients with Yersinia infection and HLA-B27.
