Current diagnostic approaches to invasive candidiasis in critical care settings

MYCOSES, Issue 5 2010
Javier Pemán
Summary For the specialist, the management of invasive candidiasis infections, from diagnosis to selection of the therapeutic protocol, is often a challenge. Although early diagnosis and treatment are associated with a better prognosis, apart from cases with positive blood cultures or fluid/tissue biopsy, diagnosis is neither sensitive nor specific, relying on many different factors, clinical and laboratory findings but there is certainly a need for the specific markers in this disease. Recently, new serodiagnostic assays as Candida albicans germ-tube antibodies or (1,3)-,- d -glucan detection and molecular techniques for the detection of fungal-specific DNA have been developed with controversial results in critical care setting. One of the main features in diagnosis is the evaluation of risk factor for infection, which will identify patients in need of preemptive or empirical treatment. Clinical scores were built from those risk factors. For these reasons, an approach to the new diagnosis tools in the clinical mycology laboratory and an analysis of the new prediction rules and its application situations has been made. Currently, the combination of prediction rules and non-culture microbiological tools could be the clue for improving the diagnosis and prognosis of invasive fungal infections in critically ill patients.

Treatment of invasive candidiasis with echinocandins

MYCOSES, Issue 6 2009
Andreas Glöckner
Summary Blood stream infections by Candida spp. represent the majority of invasive fungal infections in intensive care patients. The high crude mortality of invasive candidiasis remained essentially unchanged during the last two decades despite new treatment options that became available. The echinocandins, the latest class of antifungals introduced since 2001, exhibit potent activity against clinically relevant fungi including most Candida spp. In several randomised multicentre phase III trials, anidulafungin, caspofungin and micafungin showed convincing efficacy when compared with standard treatment regimens. In all trials, echinocandins were at least non-inferior to standard treatments. Anidulafungin was shown to be superior to fluconazole. Echinocandins have a favourable tolerability profile and exhibit a minimal potential for drug interactions since their pharmacokinetics is independent of renal and , largely , hepatic function. As a result of these properties, echinocandins are appropriate drugs of choice for invasive candidiasis in intensive care where many patients experience organ failure and receive multiple drugs with complex interactions.

Evaluation of antifungals in the surgical intensive care unit: a multi-institutional study

MYCOSES, Issue 3 2006
Kevin W. Garey
Summary In the USA, >50% of candidemia episodes occur in medical or surgical intensive care units (SICU). However, studies focused on patterns and rationale for antifungal use are lacking. The objective of this study was to evaluate systemic antifungal usage in SICU patients. Retrospective audit of SICU patients receiving antifungal therapy from four American hospitals. Medical records were reviewed for demographics, hospital variables, microbiology results, antifungal regimens and indications for therapy. A total of 2411 patient-days of antifungal use were evaluated in 225 patients. Fluconazole was the most frequently prescribed antifungal (1846 patient-days) followed by amphotericin B deoxycholate (251 patient-days), lipid formulations of amphotericin B (201 patient-days), itraconazole (71 patient-days), and caspofungin (42 patient-days). Antifungals were prescribed empirically (44%), for preemptive therapy in critically ill patients colonised with Candida (43%), or for candidiasis (12%). Candida species were recovered from 98% of patients with positive fungal cultures most commonly from pulmonary (53%) or urinary sources (17%). Fluconazole is the most frequently prescribed antifungal agent in SICUs and is most often prescribed for empiric or preemptive indications. Research efforts to identify patients who warrant preemptive antifungal therapy for invasive candidiasis could dramatically change antifungal prescribing patterns in the SICU. [source]

Pharmacological properties and clinical efficacy of a recently licensed systemic antifungal, caspofungin

MYCOSES, Issue 4 2005
Georg Maschmeyer
Summary Caspofungin, a semisynthetic derivative of the pneumocandin B0, is the first licensed compound of a new class of antifungal agents, the echinocandins. It attacks the fungal cell by selective inhibition of the beta-(1,3)- d -glucan synthase, which is not present in mammalian cells. In vitro studies have indicated a potent fungicidal effect on Candida species, and in vivo studies in immunocompromised animals with invasive candidiasis demonstrated a favourable outcome. In randomized clinical trials in patients with oropharyngeal/oesophageal and invasive candidiasis, caspofungin was at least as effective as amphotericin B deoxycholate, yet showed a significantly superior safety profile. Of patients with invasive aspergillosis refractory to or intolerant of other antifungal agents, 45% showed a partial or complete response to caspofungin given as a salvage treatment. Also, it demonstrated comparable clinical efficacy but superior tolerability in the empirical antifungal therapy in neutropenic patients compared with liposomal amphothericin B. Caspofungin has an excellent tolerability and a low potential for drug interactions. Thus, caspofungin represents an interesting and clinically valuable new antifungal drug that broadens the available therapeutic armamentarium for the treatment of invasive fungal infections.

Neonatal liver abscesses due to Candida infection effectively treated with caspofungin

ACTA PAEDIATRICA, Issue 5 2009
Luca Filippi
Abstract Candidiasis is relatively frequent in neonatal and pediatric intensive care units (ICUs), particularly in preterm infants less than 28 weeks of gestational age. Neonatal candidiasis shows high mortality and is often associated to poor neurodevelopmental prognosis in survivor patients. Amphotericin B and fluconazole are the first choice drugs for the treatment of neonatal candidiasis. Caspofungin is an alternative antifungal agent, which is recommended for invasive candidiasis in adults, but has been poorly experienced in neonates and infants as far as now. We report the first two infants with Candida liver abscesses treated with caspofungin. In the first infant bloodstream and liver lesions were cleared by combination therapy with fluconazole, liposomal amphotericin and caspofungin, while in the second one by caspofungin alone. Conclusion: Our observations confirm the efficacy and tolerability of caspofungin in the treatment of neonatal candidiasis refractory to conventional antifungal drugs. More extensive data are recommended in order to asses a specific neonatal schedule. [source]

Caspofungin,a new therapeutic option for oropharyngeal candidiasis

CLINICAL MICROBIOLOGY AND INFECTION, Issue 3 2004
J. Garbino
Abstract Patients with AIDS are often severely immunocompromised. These patients commonly develop opportunistic infections such as oropharyngeal candidiasis whose treatment may prove to be difficult. Caspofungin belongs to a new class of antifungal agents that have a different mode of action to azoles and polyenes. This new agent is the first inhibitor of fungal glucan synthesis to receive approval for the treatment of mucosal and invasive candidiasis and invasive aspergillosis. Caspofungin is well-tolerated and represents a substantial improvement over existing therapeutic options for patients prone to azole-resistant candida infection or who cannot tolerate amphotericin B.
