Abstract
The emergence of bacterial resistance is a global crisis. Prolonged use of antibiotics especially in acne is one issue of concern among dermatologists. Ketoconazole (KTZ) cream, a topical antifungal with anti-inflammatory and antiandrogenic actions, can decrease lipase activity of Cutibacterium acnes in vitro. We evaluated the efficacy and safety of KTZ cream in mild adult female acne (AFA) by conducting a randomized, double-blind, placebo-controlled trial using KTZ 2% and placebo cream twice daily for 10 weeks. We assessed the improvement of clinical severity, measured by AFA score graded by investigators and participants, and the change of acne count. Forty-one participants enrolled in our study. The proportion of participants with acne improvement from baseline (42.9% vs 9.5%, P = 0.015) and the success rate (45.0% vs 14.3%, P = 0.043) in the KTZ group were significantly higher than that of the placebo group. The most common adverse events were dryness and itching. The percentage change of acne count decreased significantly compared with baseline but did not differ statistically between the two groups (P = 0.268). We concluded that the KTZ monotherapy showed a plausible effect in improving AFA with excellent safety profile. It should be considered as a viable option for mild AFA treatment.

Abstract
BACKGROUNDS The placement of a self-expandable metal stent (SEMS) is widely used in patients with unresectable malignant biliary obstructions, but SEMSs are susceptible to occlusion by tumor ingrowth or overgrowth. The efficacy and safety of a novel paclitaxel-eluting biliary metal stent incorporating sodium caprate (MSCPM-III) were compared prospectively with those of a covered metal stent (CMS) in patients with malignant biliary obstructions. METHODS Patients with unresectable distal malignant biliary obstructions (n = 106) were prospectively enrolled in this study at multiple treatment centers. Stents were placed endoscopically: MSCPM-III in 54 patients and CMS in 51 patients. The patients received systemic chemotherapy regimens according to their disease characteristics. RESULTS The two groups did not differ significantly in basic characteristics or mean follow-up period. Stent occlusion occurred in 14 patients who received MSCPM-III and in 11 patients who received CMS. Time to recurrent biliary obstruction (RBO) and survival time did not differ significantly between the two groups (P = 0.84 and P = 0.29, respectively). However, tumor size at 2 months after stent insertion was significantly decreased in patients in the MSCPM-III group with bile duct cancers or those who experienced stent migration compared with the CMS group. Complications, including cholangitis and pancreatitis, were found to be acceptable in both groups. CONCLUSIONS Although compared with a CMS the MSCPM-III did not significantly influence time to RBO or survival duration in patients with malignant biliary obstructions, MSCPM-III reduced tumor volume and was used safely in humans.

Intensive care medicine. 2017;(11):1668-1677
Abstract
PURPOSE The aim of this study was to determine the impact of a biomarker-based strategy on early discontinuation of empirical antifungal treatment. METHODS Prospective randomized controlled single-center unblinded study, performed in a mixed ICU. A total of 110 patients were randomly assigned to a strategy in which empirical antifungal treatment duration was determined by (1,3)-β-D-glucan, mannan, and anti-mannan serum assays, performed on day 0 and day 4; or to a routine care strategy, based on international guidelines, which recommend 14 days of treatment. In the biomarker group, early stop recommendation was determined using an algorithm based on the results of biomarkers. The primary outcome was the percentage of survivors discontinuing empirical antifungal treatment early, defined as a discontinuation strictly before day 7. RESULTS A total of 109 patients were analyzed (one patient withdraw consent). Empirical antifungal treatment was discontinued early in 29 out of 54 patients in the biomarker strategy group, compared with one patient out of 55 in the routine strategy group [54% vs 2%, p < 0.001, OR (95% CI) 62.6 (8.1-486)]. Total duration of antifungal treatment was significantly shorter in the biomarker strategy compared with routine strategy [median (IQR) 6 (4-13) vs 13 (12-14) days, p < 0.0001). No significant difference was found in the percentage of patients with subsequent proven invasive Candida infection, mechanical ventilation-free days, length of ICU stay, cost, and ICU mortality between the two study groups. CONCLUSIONS The use of a biomarker-based strategy increased the percentage of early discontinuation of empirical antifungal treatment among critically ill patients with suspected invasive Candida infection. These results confirm previous findings suggesting that early discontinuation of empirical antifungal treatment had no negative impact on outcome. However, further studies are needed to confirm the safety of this strategy. This trial was registered at ClinicalTrials.gov, NCT02154178.

Medical science monitor : international medical journal of experimental and clinical research. 2016;:4226-4232
Abstract
BACKGROUND The aim of this study was to evaluate the efficiency, adverse effects, and pharmacoeconomic impact of empirical and preemptive antifungal therapy for febrile neutropenic hematological malignancy patients in China. MATERIAL AND METHODS Patients with febrile neutropenia during hematological malignancy were randomly divided into an empirical group and a preemptive group. The preemptive antifungal treatment was initiated if patient status was confirmed by clinical manifestation, imaging diagnosis, 1-3-β-D glucan(G) testing, and galactomannan (GM) test. The treatment was ended 2 weeks later if the patient was recovered from neutropenia. Voriconazole was used as the first-line medicine. All patients received intravenous administration of voriconazole every 12 h, with an initiating dose of 400 mg, then the dose was reduced to 200 mg. RESULTS The overall survival rate was 97.1% and 94.6% in the empirical group and preemptive group, respectively, with no significant difference observed (χ²=1.051, P=0.305). However, the occurrence rate of invasive fungal disease (IFD) in the preemptive group was 9.2% vs. 2.2% in the empirical group. Moreover, the mortality rate due to IFD was 0.7% and 2.3% for the empirical group and preemptive group, respectively. The average duration and cost of preemptive antifungal therapy were 13.8±4.7 days and 8379.00±2253.00 RMB, respectively, which were lower than for empirical therapy. However, no significant differences were observed for incidence of adverse effects and hospital stay between the 2 groups. CONCLUSIONS Preemptive antifungal therapy for patients with febrile neutropenic hematological malignancy demonstrated a similar survival rate as with empirical therapy but is economically favorable in a Chinese population.

Abstract
PURPOSE To assess the efficacy of corneal cross-linking (CXL) as an adjuvant to appropriate antifungal therapy in nonresolving deep stromal fungal keratitis. DESIGN Randomized clinical trial. METHODS Eyes with culture-positive deep stromal fungal keratitis not responding to appropriate medical therapy for a period of 2 weeks were randomized to receive either adjuvant CXL or no additional treatment. Antifungal medical therapy was continued in both groups. The prespecified primary outcome was treatment failure at 6 weeks after enrollment, defined as perforation and/or increase in ulcer size by ≥2 mm. RESULTS The trial was stopped before full enrollment because of a marked difference in the rate of perforation between the 2 groups. Of the 13 cases enrolled in the study, 6 were randomized to the CXL group and 7 to the non-CXL group. Five eyes in the CXL group and 3 eyes in the non-CXL group experienced treatment failure by 6 weeks (P = .56). In a secondary analysis, the CXL group experienced more perforations than the non-CXL group (4 vs 0, respectively; P = .02). CONCLUSION CXL used as adjuvant therapy for recalcitrant deep stromal fungal keratitis did not improve outcomes.

Abstract
BACKGROUND The utility of Aspergillus galactomannan (GM) and β-D-glucan (BG) in liver transplant recipients remains uncertain. METHODS As part of a randomized, double-blind trial of antifungal prophylaxis in liver transplant recipients at risk for invasive fungal infections (IFIs), GM and BG were assessed in 199 patients at baseline (enrollment) and weekly thereafter for the duration of study drug. Receiver operating characteristic (ROC) analysis was used to evaluate the accuracy of these for the diagnosis of IFIs. RESULTS Overall, 46.4% of the patients at baseline had positive GM (index ≥ 0.5) and 89.6% had BG of 80 pg/mL or greater with BG level of 500 pg/mL or greater in 31.8%. Patients with invasive aspergillosis (IA) (3/3) had positive GM at baseline as did 45.5% of those without IA (P = 0.098); the area under the ROC curve for the diagnosis of IA was 0.77 (fair test, ie, good sensitivity but poor specificity). Using BG cutoff of 80 pg/mL or higher, 100% (12/12) of the patients with IFI had positive baseline BG and as did 88.9% (160/180) of those without IFI (P = 0.618); the area under the ROC curve for predicting IFIs was 0.56 (poor test). In multivariate analyses, GM positivity was associated with study site (P = 0.041), and BG positivity with renal replacement therapy (P = 0.05) and study site (P = 0.01). The GM and BG levels declined over time; positivity at subsequent time points was lower in comparison with baseline (P < 0.001). CONCLUSIONS The GM and BG tests had significant center variability and limited accuracy for the diagnosis of IFIs in high-risk liver transplant recipients.

Abstract
IMPORTANCE Invasive candidiasis in premature infants causes death and neurodevelopmental impairment. Fluconazole prophylaxis reduces candidiasis, but its effect on mortality and the safety of fluconazole are unknown. OBJECTIVE To evaluate the efficacy and safety of fluconazole in preventing death or invasive candidiasis in extremely low-birth-weight infants. DESIGN, SETTING, AND PATIENTS This study was a randomized, blinded, placebo-controlled trial of fluconazole in premature infants. Infants weighing less than 750 g at birth (N = 361) from 32 neonatal intensive care units (NICUs) in the United States were randomly assigned to receive either fluconazole or placebo twice weekly for 42 days. Surviving infants were evaluated at 18 to 22 months corrected age for neurodevelopmental outcomes. The study was conducted between November 2008 and February 2013. INTERVENTIONS Fluconazole (6 mg/kg of body weight) or placebo. MAIN OUTCOMES AND MEASURES The primary end point was a composite of death or definite or probable invasive candidiasis prior to study day 49 (1 week after completion of study drug). Secondary and safety outcomes included invasive candidiasis, liver function, bacterial infection, length of stay, intracranial hemorrhage, periventricular leukomalacia, chronic lung disease, patent ductus arteriosus requiring surgery, retinopathy of prematurity requiring surgery, necrotizing enterocolitis, spontaneous intestinal perforation, and neurodevelopmental outcomes-defined as a Bayley-III cognition composite score of less than 70, blindness, deafness, or cerebral palsy at 18 to 22 months corrected age. RESULTS Among infants receiving fluconazole, the composite primary end point of death or invasive candidiasis was 16% (95% CI, 11%-22%) vs 21% in the placebo group (95% CI, 15%-28%; odds ratio, 0.73 [95% CI, 0.43-1.23]; P = .24; treatment difference, -5% [95% CI, -13% to 3%]). Invasive candidiasis occurred less frequently in the fluconazole group (3% [95% CI, 1%-6%]) vs the placebo group (9% [95% CI, 5%-14%]; P = .02; treatment difference, -6% [95% CI, -11% to -1%]). The cumulative incidences of other secondary outcomes were not statistically different between groups. Neurodevelopmental impairment did not differ between the groups (fluconazole, 31% [95% CI, 21%-41%] vs placebo, 27% [95% CI, 18%-37%]; P = .60; treatment difference, 4% [95% CI, -10% to 17%]). CONCLUSIONS AND RELEVANCE Among infants with a birth weight of less than 750 g, 42 days of fluconazole prophylaxis compared with placebo did not result in a lower incidence of the composite of death or invasive candidiasis. These findings do not support the universal use of prophylactic fluconazole in extremely low-birth-weight infants. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00734539.

Investigation of the effects of ketoconazole on the pharmacokinetics of macitentan, a novel dual endothelin receptor antagonist, in healthy subjects.
Atsmon, J, Dingemanse, J, Shaikevich, D, Volokhov, I, Sidharta, PN
Clinical pharmacokinetics. 2013;(8):685-92
Abstract
BACKGROUND AND OBJECTIVES Macitentan is a potent, orally active, non-peptide antagonist of endothelin receptors with tissue-targeting properties, currently undergoing clinical development for the treatment of pulmonary arterial hypertension. The formation of its active metabolite, ACT-132577, as well as overall elimination of the drug, is catalyzed by the cytochrome P450 (CYP) system, predominantly CYP3A4 and to a lesser extent CYP2C19 isoenzyme. Macitentan is not a substrate of P-glycoprotein. Hepatic uptake is mostly driven by passive diffusion and is not dependent on organic anion-transporting polypeptide transport. This study aimed to investigate the magnitude of a possible effect of a potent CYP3A4 inhibitor, ketoconazole, on the pharmacokinetics of macitentan. METHODS In a two-period, randomized, open-label, crossover study, 10 healthy subjects received each of the following treatments: Treatment A in which a single oral dose of 10 mg macitentan was administered on day 1 and Treatment B which consisted of initial daily treatment with ketoconazole 400 mg for 4 days, coadministration of macitentan and ketoconazole on the fifth day and continued administration of ketoconazole for 19 additional days. RESULTS In the presence of ketoconazole, the exposure to macitentan expressed as area under the plasma concentration-time curve was increased by approximately a factor of 2 and to ACT-132577 was reduced by approximately 26 %. Macitentan was well-tolerated with or without ketoconazole in this study and no relevant differences in safety parameters between the treatments were observed. CONCLUSIONS Although macitentan metabolism is indeed affected by CYP3A4 inhibition, the changes are not considered to be clinically significant and macitentan can be administered concomitantly with CYP3A4 inhibitors without need for dose adjustment.

Abstract
Purpose To study the influence of repeated oral administration of ketoconazole, a potent CYP3A4 inhibitor, on the plasma pharmacokinetics of eribulin mesylate administered by single-dose intravenous infusion. Eribulin mesylate is a non-taxane microtubule dynamics inhibitor that is currently under development in phase I-III trials for the treatment of solid tumors. Experimental design A randomized, open-label, two treatments, two sequences, crossover phase I study was performed in patients with advanced solid tumors. Treatments were given on day 1 and day 15 and consisted of 1.4 mg/m(2) eribulin mesylate alone or 0.7 mg/m(2) eribulin mesylate plus 200 mg ketoconazole on the day of eribulin mesylate administration and the following day. Pharmacokinetic sampling for determination of eribulin plasma concentration was performed up to 144 h following administration of eribulin mesylate. Also safety and anti-tumor activity were determined. Results Pharmacokinetic sampling and analysis was completed in ten patients. Statistical analysis of dose-normalized log-transformed AUC0-∞ and Cmax indicated that single-dose exposure of eribulin was not statistically different when co-administered with ketoconazole (ratio of geometric least square means: 0.95 (90%CI: 0.80-1.12) and 0.97 (90%CI: 0.83-1.12), respectively) in patients with solid tumors. Ketoconazole had no effect on eribulin clearance and elimination half-life. The most frequently reported treatment related adverse events were fatigue and nausea, each reported in 8/12 patients. Seven patients (58.3 %) achieved stable disease as best overall response. Conclusions The results indicate that eribulin mesylate can be safely co-administered with ketoconazole. Drug-drug interactions are not expected with other CYP3A4 inhibitors.

Neoplasma. 2013;(3):315-21
Abstract
We investigated the source of fungi in the lungs of patients with hematological malignancies who had invasive pulmonary fungal infections (IPFI). We also conducted a prospective study to evaluate the efficacy of different mouthwash solutions in preventing IPFI in patients with hematologic malignancies. In order to determine the source of fungi in the lungs of 30 patients with hematologic malignancies who had IPFI, we collected samples from sites with suspected fungal infection and used PCR and sequencing for pathogen identification. For the prospective study, we enrolled 158 patients with hematological malignancies who had IPFI and randomly assigned them to one of three mouthwash groups: 1% nystatin, 2.5% sodium bicarbonate, or normal saline. Fungal staining and incidence of IPFI, oral fungal infection, and intestinal fungal infection were evaluated. We showed that 96.7% of the fungi isolated from the throats and the lungs were identical; 76.9% of the fungi from the lungs and digestive tracts were identical and, 84.6 % of the fungi from the throats and digestive tract were identical. Patients using 1% nystatin had lower incidence of IPFI (1.6%) and fungal enteritis (1.6%) than those using sodium bicarbonate (16.3% and 14.3%) or normal saline (27.7% and 12.8%). All treatments had low incidences of oral fungal infections (0 to 4.3%). Our data showed that fungi originating from mouth and throat cause IPFI. We also showed that use of a prophylactic mouthwash containing 1% nystatin was effective in preventing IPFI in patients with hematological malignancies.
