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.

In the present study, a novel broad-range real-time PCR was developed for the rapid detection of human pathogenic fungi. The assay targets a part of the 28S large-subunit ribosomal RNA (rDNA) gene. We investigated its application for the most important human pathogenic fungal genera, including Aspergillus, Candida, Cryptococcus, Mucor, Penicillium, Pichia, Microsporum, Trichophyton, and Scopulariopsis. Species were identified in PCR-positive reactions by direct DNA sequencing. A noncompetitive internal control was applied to prevent false-negative results due to PCR inhibition. The minimum detection limit for the PCR was determined to be one 28S rDNA copy per PCR, and the 95% detection limit was calculated to 15 copies per PCR. To assess the clinical applicability of the PCR method, intensive-care patients with artificial respiration and patients with infective endocarditis were investigated. For this purpose, 76 tracheal secretion samples and 70 heart valve tissues were analyzed in parallel by real-time PCR and cultivation. No discrepancies in results were observed between PCR analysis and cultivation methods. Furthermore, the application of the PCR method was investigated for other clinical specimens, including cervical swabs, nail and horny skin scrapings, and serum, blood, and urine samples. The combination of a broad-range real-time PCR and direct sequencing facilitates rapid screening for fungal infection in various clinical specimens.

Despite the relative high frequency of Candida bloodstream infection, Candida endocarditis is a rare entity. We report seven cases, which occurred during a period of 1 year in western France. Six cases were because of Candida albicans, and one pacemaker endocarditis was because of Candida parapsilosis. All patients were men and presented risk factors for candidaemia. Of the six patients with valvular involvement, five received caspofungin and two had surgical valve replacement. Three patients treated with caspofungin antifungal therapy without valve replacement were cured from endocarditis. Antifungal and surgical strategies are discussed, in particular, the possible role of new antifungal therapies and long-term suppression therapy without surgery. One patient died in the acute phase of endocarditis, three patients died of causes unrelated to infective endocarditis and three patients had a favourable outcome.

To identify demographics, clinical manifestations, and outcomes of patients with Coccidioides fungemia, we searched our institutional medical records to identify patients with Coccidioides fungemia treated between 1998 and 2008 and conducted a comprehensive search of the medical literature to identify previously reported cases. Coccidioides fungemia is an uncommon manifestation of coccidioidomycosis, a fungal infection caused by Coccidioides sp. endemic to the southwestern United States. Six Coccidioides fungemia patients were treated at our institution during the 10-year period. All 6 had underlying comorbid disease; three were receiving immunosuppressants. Three patients survived longer than 2 years. The literature review identified 107 patients, bringing the total cohort to 113 (mean age, 42 years). Forty-three patients (38%) had infection with the human immunodeficiency virus, 20 (18%) were receiving corticosteroids, 11 (10%) had solid organ transplants, and 5 (4%) were pregnant. Sites of extrapulmonary dissemination were reported for 97 (86%); the most common sites were liver (26/97 [27%]), spleen (21/97 [22%]), and meninges/central nervous system (17/97 [18%]). No patient showed evidence of endocarditis. At least 1 serologic test was positive in 45 (87%) of 52 patients for whom results were available. Overall mortality at 30 days was 62% (70/113; mean survival, 11.4 days). Survival was significantly worse in immunocompromised versus immunocompetent patients (22/72 [31%] vs. 19/36 [53%], respectively; P = .04). Lack of antifungal therapy predicted poor survival (8/38 [21%] vs. 32/65 [49%], respectively; P = .004). Coccidioides fungemia is an uncommon manifestation of fulminant, disseminated coccidioidomycosis. Survival is poorest in immunocompromised patients or those not receiving antifungal therapy.

Fungal prosthetic valve endocarditis is a rare but devastating disease. To better characterise this syndrome, we retrospectively reviewed 21 cases of fungal prosthetic valve endocarditis seen at Mayo Clinic over the past 40 years. The average patient age was 65 years with a 2 : 1 male predominance. Twelve of 21 cases (57%) occurred within 1 year of prosthetic valve placement. The aortic valve was most commonly affected, and the most common aetiological agent was Candida species, followed by Histoplasma capsulatum. Although 20 of 21 patients (95%) were immunocompetent, they had other risk factors for fungal infection. Patients typically presented with systemic signs and symptoms of infection, and cardiac imaging was abnormal in 68% of cases. Pathological evaluation of valve material was of high yield, with organisms identified in 92% of cases who underwent valve replacement surgery or had an autopsy performed. Prosthetic valve fungal endocarditis was associated with a high morbidity and mortality, with 67% of patients experiencing complications and 57% of patients dying of infection-related disease. Hopefully, with the prompt institution of early medical therapy, surgical intervention and lifelong oral antifungal suppressive therapy, cure rates will continue to improve.

Fungal infections of the heart are increasingly described especially in immunocompromised patients. Cardiac involvement can present with myocarditis, pericarditis or endocarditis. Cryptococcal endocarditis is extremely rare, with only four reported cases in the literature. The prognosis, natural history and the optimal management for cryptococcal endocarditis are not well described because of paucity of cases. We report the case of a patient with prosthetic aortic valve endocarditis due to C. neoformans. The diagnosis was confirmed with transthoracic and transesophageal echocardiogram, blood cultures that were positive for C. neoformans and high titers of cryptococcal antigen in the serum. The patient was successfully treated with liposomal amphotericin without surgical intervention.

Coincident with an increased use of cardiac rhythm management devices (CRMD) has been an increase in the number of pacemaker and cardioverter-defibrillator infections. CRMD endocarditis accounts for about 10% of all device-related infections, and cardiac infection caused by Candida sp. is a rare event. To date, only sporadic reports of this unusual and life-threatening event have been reported. By describing a case of CRMD-related Candida endocarditis and conducting a literature review, we provide a detailed characterisation of this unusual clinical entity with an emphasis on diagnosis, management and treatment. A case of CRMD-related Candida endocarditis is presented and a computer search for confirmed cases of CRMD-Candida endocarditis was conducted. Current recommendations for management and treatment were documented. From 1969 to 2009, 15 patients with CRMD-Candida endocarditis (12 pacemaker and three implanted cardioverter-defibrillator) were documented. All were males, non-albicans Candida sp. were frequently recovered, a major fungal embolus occurred in 27% of patients and two of 10 patients who received defined antifungal therapy and device explantation expired. CRMD Candida endocarditis is a rare and serious clinical event; isolates can include Candida albicans and other Candida sp., and treatment involves both targeted antifungal therapy and device removal.

Fungal endocarditis (FE) is a rare complication in immunocompromised patients which is difficult to diagnose and has been characterized by excessive mortality (> 50%) and morbidity, regardless of treatment. The lack of clinical trials due to the small number of cases contributes further to a poor outcome. In our two cases of aspergilllus endocarditis we reviewed the clinical features, echocardiographic findings, microbiologic data, treatment, and outcome of these 2 cases and provide a current characterization of the syndrome. In this paper we have demonstrated the diversity of presentation of a critical fungal infection in immunocompromised but non neutropenic paediatric patients. The prompt diagnosis and initiation of treatment is crucial for a favourable outcome along with the use of double antifungal treatment with liposomal amphotericin and voriconazole initially which could be later switched to oral voriconazole with a good tissue penetration. Histological samples as well as radiological evidence and echocardiograms should be reviewed by experienced clinicians in order to aid diagnosis and promptly initiate treatment for these patients in order to achieve a favourable outcome.

Aim. To describe keratitis due to Chaetomium sp. occurring in a 65-year-old woman who presented with a corneal ulcer with hypopyon of the right eye with a history of trauma by vegetable matter. Method. Multiple scrapings were obtained from the ulcer. A lactophenol cotton blue wet mount and a Gram-stained smear of the scrapings were made. Scrapings were also inoculated onto various culture media. Results. Direct microscopy of corneal scrapings revealed moderate numbers of septate fungal hyphae. Greenish-yellow-coloured fungal colonies with aerial mycelium were observed in culture of the corneal scrapes. On the basis of colony characteristics and conidial structure, the fungal isolate was identified as Chaetomium sp. The patient was treated with topical natamycin (5%) hourly and cyclopentolate 1% drops 3 times a day. After 4 weeks of therapy, the hypopyon had disappeared, the epithelial defect had healed, and the stromal infiltration had almost completely resolved; the visual acuity of the eye improved from hand movements to (1/2)/60. Conclusion. Fungi of the genus Chaetomium, which are rare causes of human disease (systemic mycosis, endocarditis, subcutaneous lesions), may also cause ocular lesions.
