Recurrent valvular replacement due to exacerbation of Behcet's disease by Streptococcus agalactiae infection.

Valvular heart complications in Behcet's disease are rarely reported. Moreover, the risk of dehiscence in postoperative valvular replacement is high in Behcet's disease. We report a case of recurrent aortic prosthetic dehiscence revealing Behcet's disease in a young woman. Each disease exacerbation was concomitant to a Streptococcus agalactiae infection. This infection appears to act as a trigger for Behcet's disease exacerbation. The patient was successfully treated with immunosuppression plus antibiotic therapy.
