Bilateral Iritis after Vaccine for Bladder Cancer.

Purpose: Bacille Calmette-Guérin (BCG) is a vaccine that can be instilled into the urinary bladder as immunotherapy against superficial bladder cancer. Several case reports have implicated intravesical BCG in the development of uveitis. Patients treated with BCG therapy may present with systemic symptoms resembling reactive arthritis and, less frequently, have ocular adverse effects including bilateral panuveitis or chorioretinitis. In all but three previously reported cases of uveitis associated with BCG treatment, HLA-B27 has been positive. No patients have been reported to be positive for rheumatoid factor or antinuclear antibody (ANA).

Case Report: An HLA-B27-negative and low-positive ANA patient presented with bilateral uveitis after treatment with BCG therapy for superficial bladder cancer.

Conclusions: There is a need for greater awareness among urologists, primary care physicians, and optometrists of the potential for BCG to cause uveitis. These doctors should look for indicators of uveitis, such as circumlimbal conjunctival injection, photophobia, irregular pupils, and keratic precipitates. Together with appropriate treatment or prompt referral, this could prevent unnecessary morbidity. Future studies are needed to further elucidate the possible reasons for ANA positivity in these patients and the future role of the test in diagnosis and management.
