A 44-year-old man died suddenly, shortly after admission to the hospital with complaints of abdominal pain. Medical history was significant for chronic alcoholism and homozygous hemoglobin C disease. Autopsy revealed vegetations on the aortic valve, especially on the left coronary cusp. There was anomalous origin of the coronary arteries from the left sinus of Valsalva. The large vegetation on the left coronary cusp had extended into the left main-stem coronary artery and obstructed it. There was evidence of prior embolization to the right coronary artery with mycotic aneurysm formation and myocardial infarction. Other lesions included a cerebral artery mycotic aneurysm and metastatic abscesses within the myocardium and spleen. Although the aortic valve was free of underlying chronic pathology, the causative organism was Streptococcus viridans. This case illustrates several unusual, and, in some instances, unique findings in infective endocarditis.

Infective endocarditis is an uncommon manifestation of group B streptococcal disease. Seven cases of group B streptococcal endocarditis are reported herein. Another fifty-five cases published in the literature since 1962 are reviewed: the male to female ratio was 1.4:1. The average age was 53.8 years, and 45% of patients were 60 years of age or older. Two cases of nonsocomial endocarditis and two cases of polymicrobial endocarditis were identified. There were five cases of prosthetic valve endocarditis. Mitral and aortic valvular involvement were present in 48% and 29% of cases, respectively. Underlying heart disease was found in more than half of the cases. Rheumatic heart disease was the commonest underlying cardiac condition. Noncardiac underlying conditions included diabetes mellitus, alcoholism, pregnancy, intravenous drug abuse, and genitourinary disease. Onset was varied as was initial presentation of the disease. Large arterial thrombi were common. Overall mortality was 43.5%. Penicillin is the treatment of choice for group B streptococcal endocarditis. However, based on in vitro and in vivo studies as well as case reports, some authors feel that the combination of penicillin and an aminoglycoside is a superior regimen. Cephalothin or vancomycin are alternatives for patients who are allergic to penicillin.

The group G streptococcus has surfaced in the past 10 to 15 years as an important opportunistic and nosocomial pathogen. Although more precise organism recognition accounts for a portion of these cases, there can be little doubt that the group G streptococcus has become a more prevalent pathogen. Commercial kits, utilizing staphylococcal coagglutination or latex agglutination, are now available, affording all clinical laboratories the opportunity to identify this organism easily. Published reviews encompassing the experiences of a single institution or even several institutions affiliated with a single medical center, particularly as they were influenced by referral patterns, did not reflect the broad scope of infections that we discovered by extending our survey into the community, beyond the medical center complex and its immediate affiliated hospitals. Although malignancy is the single most obvious background factor, alcoholism and diabetes are also important host determinants of infection. Skin and soft-tissue infections (and surface sources of infection) are equally important among patients with or without the element of malignancy. Polymicrobial infection, including polymicrobial bacteremia, is an important feature, with S. aureus infections accounting for most of these cases, relating to the skin and soft tissue sources of infections so commonly seen. We saw a panorama of problems including endocarditis, septic arthritis, pleuropulmonary infections, bone and joint infections, puerperal sepsis and neonatal infection, peritonitis and ophthalmitis; we also saw a significant number of patients with bacteremia and no apparent primary source of infection. Response to antibiotic therapy was dictated by the nature of the underlying diseases, and individuals without a background of malignant disease did well, particularly those with skin and soft-tissue infections. While the literature suggests that patients with endocarditis and septic arthritis due to this organism respond poorly to antibiotic therapy, implying that such failures relate to in vitro antibiotic phenomena, we preferred to examine the problem from the viewpoint of the host(s) involved. Subacute endocarditis and acute endocarditis due to the group G streptococcus may be clinically separable, and thus require separate therapeutic approaches. In patients with septic arthritis, prosthetic devices, prior joint disease and immunosuppressive diseases and therapy often adversely influence the response to antibiotic therapy.(ABSTRACT TRUNCATED AT 400 WORDS)

A patient with a history of alcoholism and drug abuse who developed Pseudomonas cepacia endocarditis is described. The organism was found to be resistant in vitro to all common antimicrobial agents except chloramphenicol and trimethoprim-sulfamethoxazole. Treatment failed with penicillin and streptomycin and later with chloramphenicol. Orally administered trimethoprim-sulfamethoxazole, however, resulted in sterilization of the patient's blood and aortic valve which was resected 27 days after the start of therapy. A 6-week course of therapy was completed and, to date (6 months after treatment), there has been no recurrence.

Sixty-seven patients were treated with moxalactam in a noncomparative trial of hospitalized patients; 32 had endometritis or chorioamnionitis, 12 had skin and soft tissue infections, 5 had osteomyelitis, 5 had pneumonia, 5 had urinary tract infections, 4 had arthritis, 2 had sepsis from an unknown source, 1 had endocarditis, and 1 had peritonitis. Bacteremia was present in 12 of these patients. Patients were given 3 to 12 g of moxalactam per day (mean, 6.24 g/day) in divided doses every 6 to 8 h. Seven patients were given intramuscular treatment for 3 to 20 days for part or all of their therapy. The rest were given intravenous treatment exclusively. Treatment was continued for 2 to 42 days (mean, 10 days). The dose and the duration of therapy were determined by the type of infection and the response of each patient. There were four treatment failures and one enterococcal-clostridial superinfection. Moxalactam was well tolerated. Allergic reactions led to the discontinuation of the antibiotic in three patients. Prolonged prothrombin and partial thromboplastin times were observed in 2 of 11 patients tested; in both instances in patients had severe underlying diseases, including malnutrition and alcoholism. Pain on intramuscular injection was noted in two patients receiving 1,500 mg, but not in five receiving a lower dose; in one case the pain forced the use of intravenous therapy after one dose, and in the other case the pain was mild and the patient was treated for 20 days. We concluded that moxalactam was effective in the treatment of the types of infections included in this study and produced few adverse reactions.

Among 369 patients with native valve infective endocarditis observed during a 14-year period, 17 were related to S: pneumoniae. Fourteen of them were observed in the last 7 years. At the time of admission 13 exhibited purulent meningitis, 6 of them being comatose. An apparent portal of entry was present in 13 patients including Pneumonia (n = 11) and otitis media (n = 2). Major alcoholism was present in 6 cases. The mean delay between the onset of fever and the discovery of the cardiac murmur was 15 days (range 1 to 60). Twelve patients exhibited congestive heart failure with acute pulmonary oedema in 9. The aortic valve was involved in 12 and the mitral valve in 7 (in 2 patients both mitral and aortic valves were involved). Myocardial and/or annular abscesses were found in 7 patients. Nine patients underwent surgical procedure (3 died) whereas 6 comatose patients were not operated on and died. The overall mortality was 59%. Although antibiotics are effective, the severity of anatomical lesions leads to prompt surgical treatment. The high mortality is mainly due to purulent meningitis.

Four cases of infectious arthritis due to beta hemolytic streptococci, Lancefield Group G are described. Three patients presented with acute polyarthritis involving unusual sites while the 4th patient had acute monoarthritis. All 4 cases had underlying diseases which predisposed them to infection: alcoholism (2 cases), malignant disease (1 case) and diabetes mellitus (1 case). Three patients had coexistent Group G streptococcal infection: endocarditis in 2 and skin infection in 1. With adequate parenteral antibiotic therapy and frequent joint aspiration, the prognosis for return of normal joint function following infection with Group G streptococcus appears to be excellent. These cases demonstrate the need for routine serogrouping of streptococcal isolates in patients with septic arthritis. The importance of recognizing this uncommon type of infectious arthritis is emphasized in view of its prognostic and therapeutic implications.

A 28-year-old man with a history of rheumatic heart disease, alcoholism and amphetamine abuse presented with severe left upper quadrant abdominal pain and persistent fever. He stayed at home for the previous two months due to intermittent dull lower abdominal pain, chills, fever and tarry stools without seeking medical help. A diagnosis of infective endocarditis with splenic infarcts and a renal infarct was made based on the echocardiographic and abdominal computer tomography scan findings. His clinical course was complicated by an acute inferior wall myocardial infarction and cerebral hemorrhage. Despite aggressive medical treatment, his condition deteriorated. One month later, his condition became more critical with pneumonia and intractable shock, and his family requested his discharge. He died soon after leaving the hospital.
