In vitro interactions of AT406, a novel IAP antagonist, and azoles including itraconazole, voriconazole, and fluconazole against planktonic cells and biofilms of Candida albicans and Exophiala dermatitidis were assessed via broth microdilution checkerboard technique. AT406 alone exhibited limited antifungal activity. However, synergistic effect between AT406 and fluconazole was observed against both planktonic cells and biofilms of C. albicans, including one fluconazole-resistant strain. Moreover, synergism was also demonstrated between AT406 and itraconazole against both planktonic cells and biofilms of E...

From 2009, Candida auris has emerged as a multidrug-resistant ascomycete yeast pathogen with the capacity for easy transmission between patients and hospitals, as well as persistence on environmental surfaces. Its association with high mortalities, breakthrough and persistent candidaemia, inconsistencies in susceptibility testing results, misidentification by available commercial identification systems and treatment failure, complicates its management and detection. Within the last nine years, C. auris has been increasingly reported from far-Eastern Asia, the Middle East, Africa, Europe, South and North America with substantial fatalities and misidentification...

The mortality of acute-on-chronic liver failure (ACLF) patients complicated with invasive pulmonary aspergillosis (IPA) was extremely high. We aimed to explore prognostic value of the Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) lung score and to establish an optimal voriconazole regimen for ACLF patients complicated with IPA. We retrospectively screened hospitalized ACLF patients in our hospital from July 2011 to April 2016, from which 20 probable IPA cases were diagnosed. Along with onsets of IPA, deteriorated diseases severity, especially lung conditions were found in those 20 ACLF patients...

INTRODUCTION: Invasive fungal infections are an increasing cause of mortality and morbidity in high risk patient populations such as those on immunosuppressive therapy. Triazole antifungals are recommended for the prevention and treatment of such infections. The aim of this study was to develop and validate a simple, sensitive and robust LCMS/MS method for the simultaneous analysis in human plasma of three frequently used antifungal drugs: voriconazole, posaconazole, and itraconazole...

Scedosporium apiospermum is a rare cause of infection but is increasingly being reported among immunocompromised individuals around the world. We report two cases of S. apiospermum, one of keratitis and the other of nasal polyp both from immunocompetent patients. The two cases were successfully treated with voriconazole. It is important to diagnose such infections as their antifungal susceptibility to amphotericin B is variable.

A 19 year female, presented with life threatening haemoptysis and cough with minimum expectoration for 3 months. Bronchoscopy showed multiple nodules in airway. The direct microscopy and culture of sputum revealed fungal elements and Aspergillus flavus respectively. Serum Galactomannan was positive. Thus diagnosis of invasive aspergillus tracheo-bronchitis made. She responded to voriconazole. Aspergillus tracheo-bronchitis is a rare form of invasive pulmonary aspergillosis in immuno-competent host. Aspergillus spp in respiratory samples should not be routinely discarded as colonization...

Therapeutic concentrations of voriconazole in invasive fungal infections (IFIs) are ensured using drug monitoring approach, which relies on attainment of steady state pharmacokinetics. For voriconazole, time to reach steady state can vary from 5-7 days, not optimal for critically ill patients. We developed a population pharmacokinetic/pharmacodynamic model-based approach to predict doses which can maximize the net benefit (probability of efficacy - probability of adverse events) and ensure therapeutic concentrations, early on during treatment...

Invasive and allergic infections by Aspergillus flavus are more common in tropical and subtropical countries. The emergence of voriconazole (VRC) resistance in A. flavus impacts the management of aspergillosis as azoles are used as the first line and empiric therapy. We screened molecularly confirmed 120 A. flavus isolates obtained from respiratory and sino-nasal specimens in a chest hospital in Delhi for azole resistance using CLSI BMD method. Overall, 2.5% (n=3/120) of A. flavus isolates had VRC MICs above epidemiological cutoff values (>1μg/ml)...

RATIONALE: Cerebral aspergillosis (CA) is a rare manifestation of invasive aspergillosis. It usually affects seriously immunocompromised hosts. Pancreatic bacterial or/and fungal infection is common in patients with severe acute pancreatitis. PATIENT CONCERNS: We report the first case of an immunocompetent woman with infected necrotizing pancreatitis due to multidrug resistant Acinetobacter baumannii who, in the course of treatment, developed isolated CA. DIAGNOSES: Magnetic resonance imaging, rather than computed tomography, revealed latent homolateral sinus disease-the possible source of the Aspergillus infection...

Acanthamoeba keratitis (AK) is an unusual infectious disease of the cornea which sometimes leads to blindness. We report the experience of adding oral voriconazole in conjunction with topical antiacanthamoebic drops to treat refractory AK. A 20-year-old girl experienced a deep stromal keratitis with large epithelial defect in the left eye, suspected as AK. The initial best-corrected visual acuity (BCVA) of the eye was counting finger. She received topical chlorhexidine 0.02% and voriconazole 1% during the first 14 days but in vain...

Mycotic aneurysms are a fatal manifestation of disseminated fungal infections in immunocompromised hosts. We present a patient with an Aspergillus mycotic aneurysm after hematopoietic cell transplant. Due to CYP2C19 rapid metabolizer phenotype (*1/*17), therapeutic levels of voriconazole were unobtainable. Successful therapy was achieved with posaconazole salvage therapy and early, aggressive surgery. This case demonstrates the consequences of voriconazole rapid metabolism and the potential impact of genetic variants...
