Simple quantitative serological tests demonstrating Staphylococcus epidermidis agglutinins and C-reactive protein were used for the early detection of ventriculo-atrial shunt colonization by this organism. Tests in normal children and adults in various age groups throughout life confirmed Bayston's ovservations that those tested attained a titre up to 1:160 TO S. epidermidis agglutinogen. In contrast, the titre in children with colonised shunts and in adults with S. epidermidis endocarditis, both conditions which are usually accompanied by bacteraemia, rose to much higher levels, sometimes up to 1:5120. The routine combination of both tests has proven to be of considerable diagnostic value, particularly in early or recent colonisation.

A 40-year-old woman in whom the mitral valve had to be replaced with a prosthetic one (St. Jude's) had to be reoperated 8 months later because of endocarditis on the second prosthetic valve (Carbo-Medics). Four months later her general condition deteriorated progressively with cough and dyspnoea, requiring hospitalization. Auscultation revealed moist rales over both lung bases; heart sounds were distant but otherwise normal. The "international normalized ratio" was 2.5, while erythrocyte sedimentation rate, white cell count and C-reactive protein were normal. Transthoracic echocardiography demonstrated a hardly moving mitral valve prosthesis with an opening area of 0.8 cm. Subsequently this decreased further and measurement of the anticardiolipin antibody titre revealed an IgG fraction of 37.9 U/ml (normal up to 12 U/ml). Within 48 hours thrombolysis with streptokinase had increased the valve's opening area to 1.8 cm. The patient made an uneventful recovery under strict anticoagulation. This case illustrates that the anticardiolipin syndrome can be a cause of an otherwise unclear genesis.

A case of active prosthetic valve infective endocarditis (PVE) due to Candida glabrata was successfully treated by the systemic administration of fluconazole. A 66-year-old Japanese man with infective endocarditis of unknown etiology underwent aortic and mitral valve replacement to treat severe aortic and mitral regurgitation associated with multiple organ failure. Postsurgical cultures of arterial blood were repeatedly positive for C. glabrata, and therefore fluconazole was administered either intravenously or orally at a dose of 400 mg/day for 46 days. During that time the signs of inflammation including fever such as an elevated white blood cell count and the presence of C-reactive protein (CRP) all improved while the blood cultures became negative. Fluconazole is thus considered to be effective in treating PVE caused by C. glabrata. When administering this treatment, it is also important to monitor the patient's renal and liver function.

We reviewed clinical course and surgical outcome of 31 patients with native valve endocarditis who underwent an operation between 1980 and 1994. In the present study, 15 patients who manifested a neurologic complication associated with endocarditis and/or those who had a periannular abscess were assigned as 'clinical active'. Comparing with non-active group (n = 16), clinical active group included more patients with increased C-reactive protein level and those with histological acute inflammatory reaction on excised valvular tissue. Optimal timing of the operation and surgical procedures for aortic root reconstruction were significant problems in the active group. Actuarial probability of survival at 5 postoperative year was 50.8 and 87.5% in the active and non-active group, respectively. The results suggest our 'clinical activity' is a useful predictor in patients with native valve endocarditis.

A 26-year-old man who had suffered from intermittent chills and fever over a two month period was quite clear of heart or kidney involved developed acute deterioration of renal function. A new pansystolic murmur over the apex of the heart was heard on auscultation, and echocardiography clearly showed a vegetation about 0.7-0.9 cm in size on the atrial site of the mitral value. Laboratory investigation displayed normochromic anemia with negative Coombs' test. Immunological studies were positive for rheumatoid factor and circulating immune complex. High serum levels of erythrocyte sedimentation rate and C-reactive protein, nephritic sediment of urinalysis and negative blood cultures for bacteria, tuberculosis or fungus were also noted. Abdominal sonography showed normal kidney size, bilaterally. Renal biopsy revealed typical crescentic glomerulonephritis. After intravenous penicillin therapy for two weeks, the serum creatinine level recovered from 6.7 mg/dl to 2.0 mg/dl and circulating immune complex disappeared. In consideration of cardiac insufficiency and the potential risk for complications of the vegetation, the patient underwent mitral valve replacement. Four weeks after operation, all the abnormal data had resolved completely. These data suggested that infective endocarditis with rapidly progressive glomerulonephritis is curable by antibiotic therapy and surgical intervention.

The objective of this study was to evaluate the sensitivity of C-reactive protein (CRP) elevation compared to erythrocyte sedimentation rate (ESR), leucocyte count and thrombocyte count in the diagnosis of infective endocarditis (IE). It was designed as a prospective study of suspected episodes of IE in adults in tertiary care at a university-affiliated department of infectious diseases. In 89 episodes of IE, CRP was available from the start of treatment. Median age was 66 years, 45 were men and 44 women. Median CRP concentration was found to be 90 (range 0-357) mg/l with only 4% normal values. Episodes involving native valves had higher CRP than episodes occurring with prosthetic valves. Staphylococcal origin, short duration of symptoms, short duration of fever and highest recorded temperature all correlated to higher CRP levels. The CRP response was also prominent among patients > 70 years old. Among non-responders, a few cases with simultaneous cirrhosis were noted. ESR was less sensitive than CRP, with a normal level in 28% of the episodes. It was concluded that CRP determination is superior to erythrocyte sedimentation rate, leucocyte count and thrombocyte count in the diagnosis of infective endocarditis.

A 77-year-old man was referred to our hospital on October 2, 1995 because of fever and left mandibular pain beginning three months before admission. His blood pressure was 90/60 mmHg. A grade III/VI pansystolic murmur was heard over the cardiac apex. The liver was palpable 4 cm below the right costal margin. Lower extremity edema was present bilaterally. White blood cell count was 7,030/mm3 and C-reactive protein was 2.54. Enterococcus faecalis was identified by the blood culture. The diagnosis was infective endocarditis associated with congestive heart failure. He was treated by administration of antibiotics and diuretics. Mitral valve replacement and tricuspid annuloplasty were performed on October 19 because of progressive congestive heart failure with oliguria. The surgical intervention was successful despite the presence of multiple risk factors: high age, emergency, congestive heart failure and active infection. His condition improved dramatically after the operation and he was discharged two months later. Surgical intervention for infective endocarditis was a significant high-risk procedure in this uncontrollable and elderly case. This successful result suggests the indication for the timing of surgery.

A 58-year-old man was involved in an automobile accident and suffered remittent fever, leukocytosis and high C-reactive protein level. He developed a diastolic murmur 2 months after the accident. Transesophageal echocardiography showed severe aortic regurgitation with a vegetation-like echo image attached to the right coronary cusp leaflet, suggesting infective endocarditis. Intensive medical treatment for 11 months did not improve the vegetation-like echo-image, so aortic valve replacement was performed. Disruption of the right coronary cusp leaflet was confirmed surgically. Prolapse had occurred as a result of disruption during diastole. The vegetation-like echo-image was considered to be the tip of this leaflet.

Infective endocarditis caused by Kingella denitrificans occurs rarely. A review of the literature reveals only 6 cases of endocarditis caused by the bacillus. K. denitrificans is normally a commensal of the upper respiratory airways, may exceptionally be responsible for endocarditis. A case of possible prosthetic endocarditis caused by K. denitrificans is presented. A 78-year-old male with Type II diabetes was admitted to the hospital complaining of fever, a sore throat and arthralgia. He underwent replacement surgery of a St. Jude medical prosthesis for aortic stenosis at the age of 75. The only physical findings at admission were a temperature of 38.2 degrees C and murmurs of mild mitral regurgitation. The liver and spleen were not palpable, and there were no skin or eye lesions. Laboratory findings were as follows: white blood cell count 9500/microliters with 77% neutrophils, erythrocyte sedimentation rate 71 mm/h (Westergren), blood urea nitrogen 50.2 mg/dl, serum creatinine 1.7 mg/dl and C-reactive protein 22.2 mg/dl. The Gram-negative bacillus isolated from the blood was identified as K. denitrificans by the identification system, namely ID test.FN-20 rapid (Nissui, Japan). Although an echocardiogram detected no vegetation, infective endocarditis was diagnosed because the same bacillus was detected by separate blood cultures and an obvious source of infection was not found other than the prosthetic valve. Initial treatment was flomoxef, which was changed to Ampicillin 2 g/day after K. denitrificans was identified. Ampicillin continued for 6 weeks. The clinical course was good and he did not require further surgery. He has been afebrile for 2 years after completing treatment. This case represents the first report of prosthetic valve endocarditis caused by K. denitrificans in Japan.

We analyzed 118 consecutive cases of pathologically proven infective endocarditis (100 cases of native valve endocarditis [NVE] and 18 cases of prosthetic valve endocarditis [PVE]) with use of the Beth Israel criteria, the Duke criteria, and our suggested modifications of the Duke criteria; we found improved diagnostic sensitivity with our modifications. These modifications included the following additional minor criteria: the presence of newly diagnosed clubbing, splenomegaly, splinter hemorrhages, and petechiae; a high erythrocyte sedimentation rate; a high C-reactive protein level; and the presence of central nonfeeding lines, peripheral lines, and microscopic hematuria. Analysis of the pathologically proven cases of NVE showed that 64% were probable by the Beth Israel criteria, 83% were definite by the Duke criteria, and 94% were definite by our modified Duke criteria. For the pathologically proven cases of PVE, 50% were probable by the Beth Israel criteria, 50% were definite by the Duke criteria, and 89% were definite by our modified Duke criteria. All cases of NVE and PVE rejected by the Duke criteria remained rejected by our modifications. Therefore, our modifications improved diagnostic sensitivity while retaining specificity.
