Paecilomyces variotii (P. variotii) is an extremely rare cause of continuous ambulatory peritoneal dialysis (CAPD) peritonitis. When diagnosed, it usually portends poor prognosis. Patient's survival depends on early laboratory diagnosis and proper treatment. We herein report a P. variotii peritonitis in a patient on CAPD which is a quite rare clinical entity. Laboratory diagnosis was confirmed via both morphological analysis and DNA sequencing. Antifungal susceptibility tests were performed and interpreted according to the Clinical Laboratory Standards Institute M38-A2 guidelines...

Recently, several randomized studies have been published that will shape treatment decisions in the prevention and management of invasive mould infections. Liposomal amphotericin B is an option for empirical or targeted treatment of invasive aspergillosis or mucormycosis, but for prophylaxis therapy, the triazole class now predominates. The triazole voriconazole is currently regarded as a drug of choice for the treatment of proven or probable invasive aspergillosis, and has shown significantly higher response rates than amphotericin B deoxycholate in this setting, with fewer severe drug-related adverse events...

Infections caused by filamentous fungi represent a major burden in the ICU. Invasive aspergillosis is emerging in non-neutropenic individuals with predisposing conditions, e.g. corticosteroid treatment, chronic obstructive pulmonary disease, liver cirrhosis, solid organ cancer, HIV infection and transplantation. Diagnosis is challenging because the signs and symptoms are non-specific, and initiation of additional diagnostic examinations is often delayed because clinical suspicion is low. Isolation of an Aspergillus species from the respiratory tract in critically ill patients, and tests such as serum galactomannan, bronchoalveolar lavage 1-3-β-d-glucan and specific PCR should be interpreted with caution...

Histoplasmosis in central Europe is a rare fungal disease with diverse clinical presentations. Apart from acute pulmonary histoplasmosis and involvement of the central nervous system, the most serious clinical presentation is progressive disseminated histoplasmosis which is generally associated with severe immunodeficiency and in particular, advanced HIV-infection. Here we report on an immunocompetent female residing in a non-endemic area, presenting with progressive disseminated histoplasmosis after a remote travel history to Thailand and Costa Rica...

The purpose of this paper was to investigate the aggregation of amphotericin B (AMB) and AMB-arabinogalactan conjugate (AMB-AGC), and the interactions of these drugs with free and membrane-embedded sterols. Aggregation of AMB and AMB-AGC was studied by circular dichroic (CD) and UV absorbance spectroscopic techniques. The effect of liposomes on the spectra was utilized to investigate the interactions of aggregates with membrane-embedded sterols. Interaction with free sterols was studied by measuring sterols' effect on AMB/AMB-AGC susceptibility test...

Haematologists have been using liposomal amphotericin-B (L-AMB) since 1993 and despite the introduction of several novel antifungal agents over the past decade, their propensity to prescribe L-AMB remains unchanged. Although antifungal guidelines strongly recommend voriconazole as the drug of choice in the treatment of probable and proven invasive fungal disease (IFD), L-AMB is widely used in the real life because of its several advantages in terms of wide anti-mould spectrum, tolerability and efficacy. Furthermore, the concept that L-AMB is endowed with immune-modulating effects, which may have a role in fighting IFD, represent another reason for its use in patients who do not tolerate an excess of inflammation...

Pulmonary mucormycosis (PM) is a life-threatening fungal infection in patients with hematologic malignancies, and early and accurate diagnostic modalities are urgently needed. We conducted a polymerase chain reaction (PCR) assay targeting these fungi in peripheral blood from four patients with hematologic malignancies who were strongly suspected of having PM. In these four patients, the Rhizopus species was identified in two patients, and the Cunninghamella and Absidia species in one each. Based on these molecular findings, all of the patients were successfully treated via targeted therapy with liposomal amphotericin B...

Cryptococcal meningoencephalitis is a rapidly lethal infection in immunocompromised patients. Induction regimens are usually administered for 2-weeks. The shortest effective period of induction therapy with liposomal amphotericin B (LAmB) is unknown. The pharmacodynamics of LAmB were studied in murine and rabbit models of cryptococcal meningoencephalitis. The concentrations of LAmB in plasma and brain of mice were measured using HPLC. Histopathological changes were determined. The penetration of LAmB into the brain was determined by immunohistochemistry using an antibody directed to amphotericin B...

Saprochaete capitata (formerly known as Blastoschizomyces capitatus, Trichosporon capitatum, Geotrichum capitatum) is a rare but emerging yeast-like fungus. It is commonly found in environmental sources and can be isolated from skin, gastrointestinal system and respiratory tract of healthy individuals as well. It mainly infects patients with hematological malignancies such as acute myeloid leukemia (AML), especially in the presence of neutropenia; and mortality rates are high in those patients. Although the data about the in vitro antifungal susceptibility are limited, it is being reported that amphotericin B and voriconazole are more effective on S...

Cutaneous leishmaniasis (CL), a common condition in many parts of the world, is being increasingly encountered in non-endemic countries secondary to immigration. The clinical manifestations and course can vary substantially, with appropriate management ranging from observation for self-healing lesions to urgent treatment to prevent damaging anatomical and cosmetic sequelae. While there are now several effective medications, optimal therapy is not well defined, and decision-making can be challenged by the location of lesions and various drug issues, including availability, mode of delivery and adverse effects...

Phaeohyphomycosis is a rare but emerging disease caused by dematiaceous fungi. Here we describe the case of an immunosuppressed dog with disseminated phaeohyphomycosis secondary to Bipolaris spicifera infection. Regionally extensive infiltration of the paw pads, skin, myocardium, liver, renal interstitium and diaphragm was identified on histopathology. Candida glabrata and Fusarium oxysporum were also cultured from multiple sites post-mortem. The dog was treated with fluconazole, itraconazole, terbinafine and liposomal amphotericin B, but was euthanized due to its poor prognosis after 12 days of therapy...
