A 10-year analysis of 113 cases of staphylococcal endocarditis seen in two Washington, D.C., hospitals is presented. 96% of the cases occurred in parenteral drug addicts, but 4% complicated septicemia from known foci of infection. Coagulase positive staphylococcus was responsible for 97% of the infection, and the rest were caused by coagulase negative staphyloccus. Except in four patients with previously known cardiac murmurs, infection occurred on normal valves in these patients. Infection was isolated to the tricuspid valve in 71%, to the mitral valve in 6% and to the aortic valve in 3.5% of our cases; and more than one cardiac valve was affected in the remaining patients. All patients were treated with antibiotics based on bacterial sensitivity testing. The mortality from isolated tricuspid endocarditis was 5%, from isolated mitral endocarditis 33%, and from isolated aortic valve endocarditis 100%. The overall mortality was 18%. The better prognosis documented for acute tricuspid endocarditis is related to the much less severe haemodynamic consequences of acute tricuspid regurgitation, and the probably milder consequences of septic pulmonary embolism compared with coronary or cerebral embolism.

As long as the illicit use of heroin and other drugs continues in our society, infective endocarditis will remain a significant medical problem in the drug-using population. The majority of infections are produced by S. aureus, and the tricuspid valve is most commonly involved. Addicts, unlike the general population, may also develop endocarditis with a variety of gram-negative bacilli and have a higher incidence of fungal infection. The outcome of each individual infection is dependent on the prompt recognition of the underlying valvular infection and the institution of antimicrobial therapy. Infection of the tricuspid valve has a much more favorable prognosis than does infection of the aortic or mitral valves. Fungal endocarditis, and frequently gram-negative bacillary endocarditis, require valvular surgery to effect a cure.

Five heroin addicts were treated for endocarditis caused by Pseudomonas cepacia. Two of these infections occurred in patients with no known heart disease whereas the others occurred at sites of previous endocarditis or valve prostheses. Infection was indolent in four patients but was associated with shock and skin lesions suggestive of ecthyma gangrenosum in the fifth. After failure of chloramphenicol and kanamycin, all patients were treated with a combination of sulfamethoxazole, trimethoprim and polymyxin plus heart valve resection or replacement.

Infection of 300 mice of the Swiss race with Coxsackie B3 viruses gave rise to chronic myocarditis and endocarditis. The virus was cultured from the heart muscle 9 days post infection. Between days 18 and 108 post infection, virtually all mice showed evidence of an active inflammatory process in the myocardium, and in one half there was proliferation of endothelial cells, and infitration and fibrosis in the endocardium. Immunomorphologic studies demonstrated the precence of antiheart antibodies in the blood serum, and Coxsackie B3 antigen and immunoglobulin deposits in the myocardium and endocardium. Highest levels of antivirus antibodies were observed 18 days post infection.

Sixteen patients with coagulase-negative staphylococcal endocarditis were treated at the University of Minnesota Hospitals between January 1970 and September 1977. In six patients, endocarditis developed after prosthetic valve surgery; among the other ten patients (the medical group), eight had known antecedent valvular disease. The skin was thought to be the source of infection in eight patients, suggesting that prompt treatment of skin infections and avoidance of injections in patients with valvular disease are important measures in the prevention of this disease. Patients with prosthetic valve endocarditis were infected with antibiotic-resistant organisms and had a higher mortality than those in the medical group (83% versus 20%). Bacterial isolates from three patients with prosthetic valve endocarditis were resistant to methicillin, and two of these three isolates also were resistant to cephalothin by quantitative susceptibility testing. The only patient with prosthetic valve endocarditis to survive was operated upon early in the course of his illness. These observation, coupled with the high mortality in this series and in others, has prompted us to advocate early surgery in prosthetic valve endocarditis.

Fifteen male hemodialysis patients developed 21 episodes of S. aureus bacteremia. Infections involving vascular access were responsible for 65% of initial bacteremias. The arteriovenous fistula was the most prevalent type of access used, and thus was responsible for the majority of these illnesses. Phage typing indicated that recurrent episodes were due to reinfection rather than relapse. Complications included endocarditis, osteomyelitis, septic embolism, and pericarditis. One patient died of infectious complications. It is recommended that hemodialysis patients developing bacteremia due to S. aureus receive at least 6 weeks of beta lactamase-resistant antimicrobial therapy.

Group C streptococci are generally considered to be a rare cause of infection in man. Infections due to these microorganisms, however, are common in several animal species. To our knowledge, the literature contains only two previous cases of meningitis in man which were due to group C streptococci. In one of these cases meningitis developed as a complication of endocarditis due to group C streptococci. Our recent clinical experience with a patient with severe acute meningitis caused by group C streptococci is reported and the pertinent literature is reviewed. The illness manifested itself as a severe form of acute meningitis, with slow but statisfactory response to therapy with penicillin.

A collection of 820 isolates of streptococci and aerococci from human blood or internal organs was classified by means of a set of cultural and biochemical tests. Of these, 719 (712 streptococci and 7 aerococci) were from patients believed to be suffering from a systemic infection: endocarditis 317; a purulent lesion in an internal organ ("purulent disease") 152; bacteriaemia 250. The endocarditis streptococci included members of all recognisable taxa, but only certain of these were common: Streptococcus sanguis, 16-4%; dextran-positive and usually mannitol-fermenting strains of S. bovis (S. bovis I), 15-1%; S. mutans, 14-2%; S. mitior, 13-2%. Streptococci of the "alpha-haemolytic" taxa (S. sanguis, S. mitior and related strains) formed only 44-8% of the total. When the percentage frequency of streptococcal taxa among the endocarditis and "non-endocarditis" isolates was compared, the dextran-forming taxa (S. mutans, S. bovis I, S. sanguis, and dextran-positive streptococci otherwise resembling S. mitior) all had higher "endocarditis : non-endocarditis" ratios than did any of the non-dextran-producing taxa. Endocarditis increased in frequency with age, and showed an excess of males over females up to the age of 65 years. In young patients (less than 35 years), "alpha-haemolytic" streptococci predominated; with increasing age, the proportion of other streptococci increased progressively but the absolute numbers of isolations of "alpha-haemolytic" streptococci did not fall. Infections with S. mutans were prominent in the age-group 35-54 years and with S. bovis I at ages greater than or equal to 55 years. A history of previous heart disease was more often obtained in endocarditis due to "alpha-haemolytic" streptococci than in other streptococcal endocarditis. The streptococcus most often isolated from purulent lesions in internal organs was S. milleri (29-3%). It was associated with brain abscess, meningitis, pleural empyema and a variety of intra-abdominal abscesses. The only common predisposing factor in endocarditis was previous heart damage. In other systemic streptococcal diseases, other general or local predisposing causes could be observed, mainly in infections with the "pyogenic" groupable streptococci, the enterococci and S. milleri.

Diphtheroid endocarditis after aortic valve replacement was cured with penicillin, gentamycin and erythromycin. Infections occur most commonly on the aortic valves of men patients within two weeks after prosthetic insertion. Management with combined drug therapy based on sensitivities and clinical response are suggested. Paravalvular leaks do not necessarily require valve replacement.

Bacterial endocarditis caused by Actinobacillus actinomycetemcomitans is a rare disease. A 48-year-old man who had a Starr-Edwards aortic valve prosthesis inserted in 1972 was admitted for evaluation of confusion, headaches, anorexia, weight loss, diarrhea and weakness. Six blood cultures yielded gram-negative organisms which were subsequently identified as A. actinomycetemcomitans. Treatment with ampicillin and gentamicin resulted in cure which has been maintained after an observation period of eleven months. This represents the second report of A. actinomycetemcomitans endocarditis in a patient with a prosthetic valve.
