Introduction: The number of antifungal agents has sharply increased in recent decades. Antifungals differ in their spectrum of activity, pharmacokinetic/pharmacodynamic properties, dosing, safety-profiles and costs. Risk of developing antifungal associated hepatotoxicity is multifactorial and is influenced by pre-existing liver disease, chemical properties of the drug, patient demographics, comorbidities, drug-drug interactions, environmental and genetic factors. Antifungal related liver injury typically manifests as elevations in serum aminotransferase levels, although the clinical significance of these biochemical alterations is not always clear. Incidence rates of hepatotoxicity induced by antifungal therapy range widely, occurring most frequently in patients treated with azole antifungals for documented fungal infections.
Areas covered: This review provides an update regarding the hepatotoxicity profiles of the modern systemic antifungals used in treatment of invasive fungal infections.
Expert commentary: Understanding the likelihood and pattern of hepatotoxicity for all suspected drugs can aid the clinician in early detection of liver injury allowing for intervention and potential mitigation of liver damage. Therapeutic drug monitoring is emerging as a potential tool to assess risk for hepatotoxicity. 相似文献

Candidemia is a common invasive fungal infection with a high mortality rate. We performed a retrospective audit of candidemia at a tertiary centre in Western Australia, 2005–2014. There were 167 episodes of candidemia due to 173 isolates of Candida. Candida albicans (40.5%), Candida glabrata complex (30.6%), Candida parapsilosis complex (14.4%) were the most common species causing candidemia across the study. Of the tested isolates, 17.7% (11/62) were non-susceptible to fluconazole and 13.6% (9/66) non-susceptible to caspofungin. 22.8% (8/35) C. glabrata complex were fluconazole resistant and 17.1% (6/35) were non-susceptible to caspofungin. Candida glabrata complex was more common in the latter time period, but there were no susceptibility changes over time. In our setting, the prevalence of C. glabrata complex and antifungal non-susceptibility is high, and the prevalence of C. glabrata complex is increasing. 相似文献

Candida is one of the most common causes of nosocomial bloodstream infections. Candidemia is not confined to hematological patients, intensive care units or abdominal surgery wards, but it is remarkably frequent in the internal medicine setting. High mortality associated with candidemia can be reduced by prompt, appropriate antifungal therapy. The epidemiology of species has been shifting toward non-albicans strains. Significant improvements in nonculture-based diagnostic methods, such as serological markers, have been made in recent years, and novel diagnostic techniques should be further studied to enable early pre-emptive therapy. Treatment guidelines indicate that echinocandins are at present the best choice for patients who are severely ill or possibly infected with fluconazole-resistant strains. 相似文献

Invasive Candida spp. infections are increasingly diagnosed in critically ill patients. For initial treatment, an echinocandin is recommended with a possible step‐down to fluconazole when the patients’ condition is improving and the isolate appears susceptible, but there are no data to support such policy. We studied the safety and efficacy of step‐down therapy in critically ill patients with culture proven deep seated or bloodstream infections by C. albicans susceptible to fluconazole. All patients admitted into the intensive care unit from January 2010 to December 2014, who had a culture proven invasive C. albicans infection and received initial treatment with an echinocandin for at least 4 days were included. Data on patient characteristics, treatment and vital outcomes were assessed. Of the 56 patients, 32 received step‐down fluconazole therapy, at median day 5, whereas the echinocandin was continued in the other 24. No differences where seen in baseline characteristics or risk factors for invasive C. albicans infection between the two groups. Response rates were similar and no difference where seen in 28‐day or 90‐day mortality between the groups. Step‐down therapy to fluconazole may be safe and effective in critically ill patients with invasive infections by C. albicans, susceptible to fluconazole, who have clinically improved as early as 4 days after start of treatment with an echinocandin. 相似文献
