Gonococcal endocarditis in a patient with mitral valve prolapse: study of host immunology and organism characteristics.
The first case of gonococcal endocarditis on a prolapsing mitral valve is reported. The organism was found to be highly sensitive to penicillin G, Arg- Hyp- Ura-, and sensitive to the bactericidal action of normal serum. This combination of characteristics in a strain of Neisseria gonorrheae causing systemic disease is distinctly unusual. With high dose penicillin therapy the immunologic parameters returned to normal and the patient made an uneventful recovery. High levels of circulating immune complexes were detected in the patient's serum.
