A 54-year-old woman was diagnosed as having septicemia secondary to infective endocarditis with aortic regurgitation which was complicated by endophthalmitis. Her septicemia was controlled by intravenous antibiotic therapy. Then the localized eye infection and the aortic regurgitation with a massive vegetation were surgically treated simultaneously. She had no relapse of infection after intensive postoperative antibiotic therapy.

We compared the efficacies of fluconazole (Flu), amphotericin B (AmB), and 5-fluorocytosine (5FC) monotherapies with the combination of Flu plus 5FC and Flu plus AmB in a rabbit model of Candida albicans endocarditis, endophthalmitis, and pyelonephritis. The dose of Flu used was that which resulted in an area under the concentration-time curve in rabbits equivalent to that seen in humans who receive Flu at 1,600 mg/day, the highest dose not associated with central nervous system toxicity in humans. Quantitative cultures of heart valve vegetations, the choroid-retina, vitreous humor, and kidney were conducted after 1, 5, 14, and 21 days of therapy. All untreated controls died within 6 days of infection; animals treated with 5FC monotherapy all died within 18 days. In contrast, 93% of animals in the other treatment groups appeared well and survived until they were sacrificed. At day 5, the relative decreases in CFU per gram in the vitreous humor were greater in groups that received Flu alone and in combination with 5FC or AmB than in groups receiving AmB or 5FC monotherapies (P < 0. 005) but were similar thereafter. In the choroid-retina, 5FC was the least-active drug. However, there were no differences in choroidal fungal densities between the other treatment groups. On days 5 and 14 of therapy, fungal densities in kidneys of AmB recipients were lower than those resulting from the other therapies (P < 0.001 and P < or = 0.038, respectively) and AmB-plus-Flu therapy was antagonistic; however, all therapies for fungal pyelonephritis were similar by treatment day 21. While fungal counts in cardiac valves of Flu recipients were similar to those of controls on day 5 of therapy and did not change from days 1 to 21, AmB therapy significantly decreased valvular CFUs versus Flu at days 5, 14, and 21 (P < 0.005 at each time point). 5FC plus Flu demonstrated enhanced killing in cardiac vegetations compared with Flu or 5FC as monotherapies (P < 0. 03). Similarly, the combination of AmB and Flu was more active than Flu in reducing the fungal density in cardiac vegetations (P < 0.03). However, as in the kidney, AmB plus Flu demonstrated antagonism versus AmB monotherapy in the treatment of C. albicans endocarditis (P < 0.05, P = 0.036, and P < 0.008 on days 5, 14, and 21, respectively).

Pseudomonas aeruginosa nowadays is encountered among the leading pathogen in (i) ICU pneumonia; (ii) nosocomial bacteremia and AIDS primary bacteremia; (iii) iv drug users endocarditis; (iv) exacerbations of cystis fibrosis; (v) malignant external otitis and 'swimmers's ear', and (vi) contact lenses keratitis and traumatic endophthalmitis. The most vulnerable nosocomial hosts are the neutropenics and the mechanically ventilated patients in whom mortality rate exceeds 30%. Virulence of P. aeruginosa is attributed to the elaboration of various enzymes and toxins. There is also worldwide emergence of multiresistant phenotypes to antipseudomonal antibiotics. Therapeutic guidelines should therefore be based on (i) continuous resistance surveillance; (ii) in vitro synergistic interactions of antibacterial agents; (iii) pharmacodynamic properties of antibiotics interpreted by optimal dosing and appropriate frequency of administration; and (iv) current information on the necessity for combination therapy using an aminoglycoside.

Endogenous endophthalmitis is a rare disease caused by hematogenic germ spread from an internal focus. Infections due to Streptococcus agalactiae are infrequent in adults although new cases had been described recently associated to inmunodepression. We present a patient with endocarditis due to Streptococcus agalactiae, endophthalmitis and multiple brain abscess. We also review the literature.

Access-related infections are the most important causes of the loss of vascular access for dialysis. These infections also may lead to devastating consequences, including sepsis with multiorgan failure; endocarditis; or metastatic infections such as vertebral osteomyelitis, epidural abscess, or endophthalmitis. A small percentage of these complications are fatal; overall, dialysis-related bloodstream infections are the second leading cause of death in patients undergoing hemodialysis, accounting for up to 10% of all deaths, and approximately three-fourths of all deaths caused by infection in patients undergoing dialysis. Moreover, vascular placement and complications account for approximately one fourth of all admissions and hospital days among patients on dialysis.

The beneficial effects of therapy combining an antibiotic and dexamethasone have been reported in human studies on meningitis and in experimental studies on septic arthritis, nephritis, and endophthalmitis. Since most patients with staphylococcal endocarditis need a combination of medical and surgical treatment, the purpose of this study was to determine whether the addition of dexamethasone to vancomycin has any beneficial effect regarding the degree of valve tissue damage or the course of experimental aortic valve endocarditis caused by a methicillin-resistant strain of Staphylococcus aureus. Rabbits with catheter-induced aortic valve vegetations were randomly assigned to a control group and to groups receiving dexamethasone (0.5 mg/kg of body weight, intravenously [i.v.], twice a day [b.i.d]), vancomycin (30 mg/kg, i.v., b.i.d), or dexamethasone plus vancomycin, for a total of 10 doses (two doses per day for 5 days). The severity of valve tissue damage was significantly less in groups receiving vancomycin plus dexamethasone compared with that of the group receiving vancomycin alone (P < 0.001). The severity of tissue damage was inversely correlated with the mean polymorphonuclear leukocyte number in valve tissue. No statistically significant differences were observed between the vancomycin-treated group and the vancomycin-plus-dexamethasone-treated group in survival, blood culture sterilization rate, or reduction of the microbial burden (in CFU per gram) in valvular tissue. In conclusion, treatment with a combination of vancomycin and dexamethasone for 5 days reduces the severity of valve tissue damage in experimental staphylococcal aortic valve endocarditis. These findings could have significant implications in the treatment of staphylococcal endocarditis and deserve further confirmation in clinical trials.

A 53-year-old female suddenly went blind in her left eye on 3 June, 2000. She was admitted to the Department of Ophthalmology of our hospital under the diagnosis of endophthalmitis. Her left eye was enucleated, and Streptococcus agalactiae was found in the vitreous fluid. After left ophthalmectomy, inflammation recurred after cessation of antibiotic administration. Echocardiography demonstrated a vegetation of the posterior mitral valve. The diagnosis was infective endocarditis. She was transferred to the Department of Internal Medicine. Mitral regurgitation deteriorated during the course of medical therapy, but she was discharged on 13 September, 2000 because inflammation had improved remarkably and the vegetation had disappeared after administration of penicillin G, panipenem, cefotaxime and clindamycin. We suspected that embolism of the ophthalmic artery was the cause of the sudden blindness in her left eye. Infective endocarditis with bacterial endophthalmitis is very rare in Japan.

Bilateral endogenous endophthalmitis is a rare condition initiated by infection by microbes in the bloodstream, such as those arising from a foci of infective endocarditis. We report a case and discuss the diagnostic aspects and the clinical outcome of a patient with characteristic findings of the disease. The patient was a 49 year old white male who had a metallic aortic valve implanted 7 months previously, and who presented to the hospital with 10 days of fever, cough and dyspnea, then diarrhea and mental confusion. On the second day of hospitalization, he experienced sudden loss of vision in both eyes. A Gram-positive coccobacillus was isolated from the bloodstream, he was treated with fluoroquinolone with disappearance of fever, decreased ocular inflammation, and improvement in his vision to light perception. He later underwent valve replacement surgery but died during the procedure. We review the occurrence of ocular signs and symptoms and their importance in patients with endocarditis.

Injection drug use can result in a variety of severe ocular conditions. Hematogenous dissemination of various fungi and bacteria may produce endophthalmitis with resultant severe visual loss. Retinal arterial occlusive disease may result from talc and other particulate emboli. Most commonly, life-threatening systemic diseases such as endocarditis and HIV infection secondarily affect the eye. Because many of these conditions may result in blindness if untreated, accurate diagnosis and prompt initiation of therapy are essential.

Infection caused by Penicillium spp. due to species other than P. marneffei is rare. We present three such cases of invasive disease. The first had chronic granulomatous disorder (CGD) with pulmonary infection caused by Penicillium spp. and he responded to amphotericin B therapy. Cases two and three were not known to be immunocompromised and both failed to respond to therapy. Case two had cerebral disease from an unknown source caused by P. chrysogenum. Case three probably acquired infection caused by P. decumbens peri-operatively and presented with paravertebral infection. The pertinent literature on invasive infections of Penicillium spp. other than P. marneffei is reviewed. From 1951 onwards, 31 reported cases of invasive disease included 12 cases of pulmonary infection (six in non-immunocompromised patients), four cases of prosthetic valve endocarditis, six cases of CAPD peritonitis, five cases of endophthalmitis, individual cases of fungemia and oesophagitis (both in AIDS), upper urinary tract infection and intracranial infection. Trauma, surgery or prosthetic material is commonly implicated in the non-pulmonary cases. Superficial infection (keratitis and otomycosis) is commonly caused by Penicillium spp. Allergic pulmonary disease, often occupational (such as various cheeseworkers' diseases), is also common. Optimal therapy for invasive infection is not established, but surgery may be advisable if possible. Amphotericin B may be the most effective antifungal drug.
