“…In these patients, the addition of gentamicin to penicillin or to ceftriaxone for at least the first 2 weeks of a 4-to 6-week course of antimicrobial therapy for group B, C, and G streptococcal IE may be considered. 132,133 There is a clinical impression 134,135 that early cardiac surgical intervention has improved overall survival rates among treated patients with β-hemolytic streptococcal IE compared with patients treated decades ago. Because of the relative infrequency of IE caused by these microorganisms, consultation with an infectious diseases specialist during treatment is recommended.…”

Background— Infective endocarditis is a potentially lethal disease that has undergone major changes in both host and pathogen. The epidemiology of infective endocarditis has become more complex with today’s myriad healthcare-associated factors that predispose to infection. Moreover, changes in pathogen prevalence, in particular a more common staphylococcal origin, have affected outcomes, which have not improved despite medical and surgical advances. Methods and Results— This statement updates the 2005 iteration, both of which were developed by the American Heart Association under the auspices of the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease, Council on Cardiovascular Disease of the Young. It includes an evidence-based system for diagnostic and treatment recommendations used by the American College of Cardiology and the American Heart Association for treatment recommendations. Conclusions— Infective endocarditis is a complex disease, and patients with this disease generally require management by a team of physicians and allied health providers with a variety of areas of expertise. The recommendations provided in this document are intended to assist in the management of this uncommon but potentially deadly infection. The clinical variability and complexity in infective endocarditis, however, dictate that these recommendations be used to support and not supplant decisions in individual patient management.

Background-Despite advances in medical, surgical, and critical care interventions, infective endocarditis remains a disease that is associated with considerable morbidity and mortality. The continuing evolution of antimicrobial resistance among common pathogens that cause infective endocarditis creates additional therapeutic issues for physicians to manage in this potentially life-threatening illness. Methods and Results-This work represents the third iteration of an infective endocarditis "treatment" document developed by the American Heart Association under the auspices of the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease, Council on Cardiovascular Disease of the Young. It updates recommendations for diagnosis, treatment, and management of complications of infective endocarditis. A multidisciplinary committee of experts drafted this document to assist physicians in the evolving care of patients with infective endocarditis in the new millennium. This extensive document is accompanied by an executive summary that covers the key points of the diagnosis, antimicrobial therapy, and management of infective endocarditis. For the first time, an evidence-based scoring system that is used by the American College of Cardiology and the American Heart Association was applied to treatment recommendations. Tables also have been included that provide input on the use of echocardiography during diagnosis and treatment of infective endocarditis, evaluation and treatment of culture-negative endocarditis, and short-term and long-term management of patients during and after completion of antimicrobial treatment. To assist physicians who care for children, pediatric dosing was added to each treatment regimen. Conclusions-The recommendations outlined in this update should assist physicians in all aspects of patient care in the diagnosis, medical and surgical treatment, and follow-up of infective endocarditis, as well as management of associated complications. Clinical variability and complexity in infective endocarditis, however, dictate that these guidelines be used to support and not supplant physician-directed decisions in individual patient management.

“…Our findings confirm previous reports on the high rate of complications associated with group G streptococcal endocarditis (7,12,15,25). The onset of the disease is usually acute, and the disease often progresses rapidly as is the case in Streptococcus pyogenes endocarditis.…”

“…Many authors now recommend combination therapy with an aminoglycoside when patients do not respond to high-dose therapy with a beta-lactam antibiotic. In the case of endocarditis the aminoglycoside should probably be added at the outset (21,25). Factors responsible for the differences in the clinical course of group G streptococcal septicemia in our patients as well as in others series remain unclear.…”

The clinical and bacteriological features of septicemia caused by group G streptococci were analyzed in nine patients seen during a period of 28 months. Four of these patients had acute endocarditis with a high rate of serious neurological complications. The clinical response to antibiotic treatment was slow in the endocarditis patients despite sensitivity of the organism in vitro. Group G streptococcal septicemia can be a very serious condition associated with endocarditis of a destructive nature. Comparison with previous reports suggests that group G streptococcal infections are of increasing importance. The virulence of group G streptococci may be changing, resulting in more serious infections and complications. This series stresses the importance of prompt recognition of this infection and the need for aggressive management of these patients.
