Nonenterococcal group D streptococcal septicemia: association with unrecognized endocarditis.
68 patients presented to the Veterans General Hospital, Taipei with nonenterococcal group D streptococcal septicemia in the years 1985-1987. 36 patients (53%) had nonenterococci as part of a polymicrobial bacteremia. The large intestine was not examined in most patients. Five patients (7%) had associated colonic carcinoma, and 17 patients (25%) had colorectal diseases. Only 7/68 patients (10%) were clinically diagnosed as having infective endocarditis by the doctors in charge. The others were regarded as having septicemia. The charts of these patients were reviewed retrospectively to diagnose infective endocarditis based on strict definitions. One (1%) had definite endocarditis proved at autopsy. 16 patients (24%) had probable endocarditis due to the presence of either a new regurgitant murmur or both a predisposing heart disease and embolic phenomena; 39 (57%) had possible endocarditis based on evidence of having either a predisposing heart disease or embolic phenomena; and only 12 (18%) had no evidence of endocarditis. 27 patients (40%) had at least one predisposing heart disease associated with endocarditis. 51 patients (75%) had at least one lesion suggesting embolic phenomena. 30 patients (44%) had electrocardiographic abnormalities. This high incidence of arrhythmia in nonenterococcal septicemia is of particular interest and could be related to cardiac involvement in some patients. The overall mortality, 62% (42/68), was extremely high in our series, but in those who were clinically diagnosed and treated as infective endocarditis, the mortality was low, 14% (1/7). We suggest all patients with nonenterococcal septicemia associated with either heart disease or lesions of CNS, lung, heart, kidney or limbs suggesting embolic phenomena should be regarded as having possible or probable endocarditis. Treating such patients as having infective endocarditis may reduce the mortality in nonenterococcal septicemia.
