Amphotericin B (AmB) and fluconazole, administered intraperitoneally for 7 days, were compared in a rabbit model for Candida albicans endocarditis. When given early, AmB was more effective than fluconazole for reducing CFU counts in vegetations (P < 0.01) and kidneys. Forty-eight hours after the last dose, AmB was still detected in all vegetations whereas fluconazole was detected in only one case.

Amphotericin B (1 mg/kg of body weight, intravenous) and fluconazole (100 mg/kg, intraperitoneal) were compared in the prophylaxis of experimental Candida endocarditis caused by drug-susceptible, non-C. albicans strains C. tropicalis and C. parapsilosis. Neither antifungal agent was effective at preventing endocarditis due to either Candida strain when either agent was administered in a single-dose regimen (1 h prior to fungal challenge); the prophylactic efficacy of both agents increased substantially when a second prophylactic dose was given (24 h postchallenge). The excellent prophylactic efficacy of fluconazole, a fungistatic agent, underscores the importance of microbistatic mechanisms in endocarditis prophylaxis.

Phialophora is a dematiaceous fungus isolated from soil and wood. Human infections including chromoblastomycosis, mycotic keratitis, cutaneous infections, and prosthetic valve endocarditis have been reported. We report a case of fatal hemorrhage due to Phialophora verrucosa in a patient with prolonged neutropenia undergoing autologous bone marrow transplant (BMT) for acute myelogenous leukemia (AML). Bacterial infections complicated induction and consolidation chemotherapies. Liposomal amphotericin B (LAMB) was given from day +33 to day +72 for febrile neutropenia. Death occurred on day +74 due to tracheal hemorrhage. Autopsy revealed granulation tissue on the posterior wall of the trachea with fungal hyphae on histopathology; the tissue grew Phialophora verrucosa. In vitro susceptibility studies revealed a minimum inhibitory concentration to AmB of 0.1 microg/ml. This represents the first reported case of invasive P. verrucosa in a BMT patient leading to fatal hemorrhage, despite large cumulative doses of LAMB to which the organism remained susceptible.

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.

Aspergillus species infections are an increasingly common occurrence in hospital wards. Aspergillus endocarditis constitutes one of the manifestations of the disease, which bears a poor prognosis in cardiac surgery patients. A review of the literature on fungal and Aspergillus endocarditis was undertaken. Valvular risk factors, indwelling intravenous catheters, prolonged antibiotics, malignancy, and intravenous drug use increase the risk. Clinical presentation is insidious, with embolic complications often representing the first manifestation of the disease. Blood cultures are typically negative. The mortality rate is almost 100%. Amphotericin B represents the mainstay of medical therapy with several possible adjuncts. Surgery is an essential part of therapy in Aspergillus endocarditis after cardiac surgery and should be undertaken as soon as the diagnosis is made. Aspergillus endocarditis is an ominous complication after cardiac surgery. A high suspicion index, early administration of appropriate antibiotics, and prompt surgical intervention should improve the prognosis, which remains dismal.

The diagnosis of fungal endocarditis requires a high index of clinical suspicion. Rarely, pacemaker implantation may be a risk factor for the development of fungal endocarditis. A 71-year-old man with a history of multiple transvenous pacemaker manipulations and fever of an uncertain source is described. A diagnosis of culture-negative pacemaker endocarditis was established only after repeat transthoracic echocardiography. Amphotericin B was instituted; however, the patient developed a cerebral infarct and died. Postmortem examination demonstrated Aspergillus fumigatus within a large pacemaker lead thrombus, tricuspid and aortic valve vegetations, and septic pulmonary and renal emboli. The present report describes the clinical and pathological features of a rare case of Aspergillus fumigatus pacemaker lead endocarditis and suggests that serial echocardiograms may be effective in the early detection of pacemaker lead vegetations. The diagnostic features and therapeutic management of pacemaker lead endocarditis are reviewed.

Rhodotorula spp. are emergent opportunistic pathogens, particularly in immunocompromised individuals. They have been associated with endocarditis, peritonitis, meningitis endophthalmitis and catheter-associated fungemia. The aim of this study was to review all cases of central venous catheter-related fungemia due to Rhodotorula spp. reported in the literature in order to determine the best management of this uncommon infection. All patients but one in the 88 cases examined had some form of underlying disease including sixty-nine (78.4%) who had cancer. Rhodotorula mucilaginosa was the species most frequently recovered (75%), followed by Rhodotorula glutinis (6%). Amphotericin B deoxycholate was the most common antifungal agent used as treatment and the overall mortality was 9.1% in this review. This fungemia is a rare disease which can be found in immunocompromised and in the intensive care patients. The use of specific antifungal therapy may be associated with an increase in the survival. It should be noted that Rhodotorula spp. is resistant to fluconazole.

This manuscript reports on two very low birth weight premature infants with respiratory distress, receiving parenteral nutrition and broad-spectrum antibiotics for about 3 weeks, who developed Candida albicans sepsis associated with fungal mycoses and endocarditis, despite treatment with Amphotericin B and Caspofungin. On days 40 and 47, respectively, antifungal therapy was modified to liposomal Amphotericin B combined with Fluconazole 6 mg/kg/day for 4 weeks, resulting in complete resolution of the mycetomas. Our observations suggest that the combination of liposomal Amphotericin B with Fluconazole is able to result in complete resolution of cardiac mycetomas in preterm infants.

Invasive aspergillosis is an opportunistic infection with a high mortality rate that usually occurs in the immunocompromised host. Several cases of fungal infections have been reported after cardiac surgery. We present here a case of Aspergillus fumigatus tricuspid valve endocarditis associated with permanent pacemaker leads. Tricuspid valve vegetectomy was done and the pacing leads were also removed. Culture from the excised vegetation grew Aspergillus fumigatus. The patient was started on IV Amphotericin B for eight weeks. The patient was subsequently followed up in the out-patient clinic, and remains afebrile after one year, with no evidence of any vegetation.

This part of the EFISG guidelines focuses on non-neutropenic adult patients. Only a few of the numerous recommendations can be summarized in the abstract. Prophylactic usage of fluconazole is supported in patients with recent abdominal surgery and recurrent gastrointestinal perforations or anastomotic leakages. Candida isolation from respiratory secretions alone should never prompt treatment. For the targeted initial treatment of candidaemia, echinocandins are strongly recommended while liposomal amphotericin B and voriconazole are supported with moderate, and fluconazole with marginal strength. Treatment duration for candidaemia should be a minimum of 14 days after the end of candidaemia, which can be determined by one blood culture per day until negativity. Switching to oral treatment after 10 days of intravenous therapy has been safe in stable patients with susceptible Candida species. In candidaemia, removal of indwelling catheters is strongly recommended. If catheters cannot be removed, lipid-based amphotericin B or echinocandins should be preferred over azoles. Transoesophageal echocardiography and fundoscopy should be performed to detect organ involvement. Native valve endocarditis requires surgery within a week, while in prosthetic valve endocarditis, earlier surgery may be beneficial. The antifungal regimen of choice is liposomal amphotericin B +/- flucytosine. In ocular candidiasis, liposomal amphotericin B +/- flucytosine is recommended when the susceptibility of the isolate is unknown, and in susceptible isolates, fluconazole and voriconazole are alternatives. Amphotericin B deoxycholate is not recommended for any indication due to severe side effects.
