Safety and pharmacokinetics of coadministered voriconazole and anidulafungin. Dowell JA, Schranz J, Baruch A, Foster G. Vicuron Pharmaceuticals, 455 South Gulph Road, Suite 310, King of Prussia, PA 19406, USA. There is considerable interest in combining echinocandin and triazole antifungal agents for treatment of invasive fungal infections; however, information is needed regarding the tolerability and potential for pharmacokinetic interactions. Anidulafungin is a semisynthetic echinocandin, and voriconazole is an extended-spectrum triazole. In a random sequence, 17 subjects received anidulafungin with placebo, voriconazole with placebo, and anidulafungin with voriconazole. Anidulafungin was administered intravenously: 200 mg on day 1, then 100 mg d on days 2 through 4. Voriconazole was administered orally: 400 mg every 12 hours on day 1, then 200 mg every 12 hours on days 2 to 4. dose-limiting toxicities or serious adverse events occurred, and all adverse events were mild and consistent with the known safety profiles of both drugs. Pharmacokinetic parameters were not affected by coadministration. The geometric mean ratio 90% confidence interval ; of the combination drug alone for AUC SS ; was 97.4% 94.9-99.9 ; , 97.4% 92.1-103.0 ; , and 94.4% 87.0-102.5 ; for anidulafungin, voriconazole, and the voriconazole metabolite, respectively.

BioMrieux, Marcy l'Etoile, France ; was used to identify C. albicans. Polyethylene glycol 400 was used to solubilize ketoconazole and itraconazole Janssen Pharmaceutica, Piscataway, NJ, USA ; , while DMSO Merck, Darmstadt, Germany ; was used to solubilize voriconazole Pfizer, Sandwich, UK ; and amphotericin B Bristol-Myers Squibb, Princeton, NJ, USA ; . Stock solutions of amphotericin B, fluconazole Pfizer, Groton, CT, USA ; , ketoconazole and itraconazole were prepared using RPMI-1640 buffered with 0.165 M MOPS t pH 7.0 Biowhittacker, Walkerville, MD, USA ; , whereas voriconazole was prepared in HR antifungal compounds were 0.0316 mg L for amphotericin B, ketoconazole, itraconazole and voriconazole, and 0.12564 mg L for fluconazole. Broth microdilution testing was performed according to the NCCLS M27-A reference method. The C. albicans inoculum size ranged between 0.5 103 3 and 2.5 10 cfu mL. In each case, the inoculum size was verified by colony counting. The 96-well plates were incubated at 37C in air. The MICs were recorded at 24 and 48 h. ATCC strains 90028 C. albicans ; , 6258 Candida krusei ; and 22019 Candida parapsilosis ; were included as controls. All isolates were biotyped by random amplified polymorphic DNA, inter-repeat PCR and electrophoretic karyotype for genetic alterations. In nine patients, consecutively obtained C. albicans isolates were found to be isogenic by all three methods. In patient 1, the first four isolates mb4389, mb1307, mb8808 and mb8456 ; were isogenic, whereas isolates mb4544 and mb8577 showed a different karyotype. According to NCCLS breakpoints, all C. albicans isolates of three children patients 1, 4 and 9 ; developed crossresistance to ketoconazole, fluconazole and itraconazole, as well as high voriconazole MICs consistent with resistance. All isolates remained susceptible to amphotericin B Table ; . All isolates that were cross-resistant to ketoconazole, fluconazole MIC 16 mg L ; . However, in patient 1 a correlation between an altered karyotype of isolates mb4544 and mb8577 and greater susceptibility to all four azoles was observed. The isolates from three children patients 2, 3 and 7 ; developed increased MICs or resistance to ketoconazole and fluconazole, but remained susceptible, dose dependently, to itraconazole and voriconazole, and were highly susceptible to amphotericin B. C. albicans isolates from four children patients 5, 6, 8 and 10 ; were susceptible to all azoles, but the MICs of fluconazole either increased four-fold patients 5, 6 and 8 ; or were already `susceptible dose-dependent' patient 10 ; , whereas all isolates remained susceptible to ketoconazole, itraconazole, voriconazole and amphotericin B.
Additional comparison group. Level of adherence to medication is a mediating interim ; outcome measure for the 2 antidepressant drug groups. For the final outcome measures, the analysis of all-cause costs is supplemented with a measure more logically related to the subject of the study--cost to treat depression and related conditions. In most situations, the claims data are still available to the researchers after the initial analyses have been completed, making investigation of possible causal mechanisms feasible. Irrespective of whether the claims data are available, evidence from the research literature e.g., similar studies conducted on other patient populations ; should be assessed and, if appropriate, used as 1 component of the explanation of process. While it is unreasonable to expect investigation of every possible explanation, no matter how far-fetched, a reasonable expenditure of time to investigate major study findings should be expected of claims database researchers. 7. Use Disclosure Not Data Torture The analytic process and the data presentation ; should begin with basic descriptive measures e.g., percentage, mean, median, and a measure of dispersion such as range or standard deviation ; for the study sample overall and for key subgroups. When used at the outset of the analytic process, basic descriptive information helps the researcher to select a statistical technique that is appropriate for the data.39 Additionally, readers can use this information to compare the study sample to their own populations on key dimensions e.g., age, gender, comorbidities, benefit design ; and determine the degree to which study results apply to them; that is, the "external validity" pragmatic applicability ; of the work outside its original setting.38 Readers who are unfamiliar with the statistical techniques employed can better grasp the gist of the study findings from and vortex.
Voriconazole vs caspofungin
Cantly delayed the growth and multiplication of C. albicans cells whereas cells exposed to voriconazole 1 mg L ; showed no substantial delay of growth and multiplication suggesting that amphotericin B and caspofungin had prolonged PAFE on C. albicans but not voriconazole. A summary of the data obtained for multiple experiments for amphotericin B, four triazoles and two echinocandins is shown in Table 1. Among various antifungal drugs we examined for their PAFE against A. fumigatus, amphotericin B is known to be fungicidal against filamentous fungi, including A. fumigatus. Amphotericin B acts on ergosterol of fungal cytoplasmic membrane and create pores through which essential nutrients and ions are leaked out of the cell. The rapid loss of essential nutrients and ions leads to the death of the fungal cell. Since amphotericin B is a rapidly acting fungicidal agent, even a brief exposure of fungal cells to it produces a prolonged PAFE. On the other hand, the echinocandins, known to be fungistatic agents against A. fumigatus, do not elicit permanent injury to the fungal cell. As soon as the drug is removed, the cells recover immediately and resume growth and multiplication. Thus, fungistatic agents are expected to produce short PAFE as opposed to fungicidal drugs. Our results on the PAFE of caspofungin and micafungin on A. fumigatus confirm this assumption. In contrast to the fungistatic activity of triazoles against pathogenic yeasts such as Candida species, these agents are fungicidal against Aspergillus species, including A. fumigatus.9, 10 Our results show that all the triazoles we used possessed short PAFE. This apparent contradiction of the fungicidal activity and the short PAFE of triazoles against Aspergillus species may be related to the mode of action of these compounds. In the case of amphotericin B, the effect on the fungal cell is direct by physically creating `pores' in the cytoplasmic membrane rendering it biologically non-functional. Since it is a physical injury, the effect is rapid and requires only short exposure e.g. 2 h ; to inflict a prolonged crippling effect on the cell. On the other hand, the fungicidal effect of triazoles on A. fumigatus is slow and it takes 1224 h to obtain 90% killing of the cells.9 This is

Community controls 2 95 2.1% ; and also among the cases of sporadic CJD 0 169 0% ; . It is generally accepted that 10 15% of the western population has an infertility problem at some point in their reproductive life. Although the frequency of infertile patients seeking medical assistance is less well known, gures ranging from 39 to 62% have been quoted Stephen and Chandra, 1995; Olsen et al., 1996; Collins, 2002 ; , with 50% representing the most accepted percentage ESHRE Capri Workshop Group, 2001 ; . Thus one should have expected an ~5% frequency of infertility treatment in both vCJD and controls, as well as in sporadic CJD. The frequency of patients receiving gonadotrophins, however, should be considerably lower. It has been reported that 16% of patients undergoing infertility treatment receive gonadotrophin treatment Collins, 2002 ; . However, following some treatment models, at least 50% may be elegible for gonadotrophin treatment Effective Health Care, 1992 ; . Thus, it would be of interest to know in detail how the history of infertility treatment was investigated. The authors stated that `we obtain a detailed medical history from relatives, which is corroborated using hospital and primary care records' Ward et al., 2004 ; . Since sometimes the information related to infertility treatment is withheld from the relatives except for the husband ; , additional data concerning the methodology followed should be given, to rule out any under-reporting. On the other hand, given the low aforementioned frequencies of infertility, it would be of interest to know the distribution regarding the number of children in vCJD, sporadic CJD and controls. We fully agree with the conclusion of Ward et al. `To date, there is no strong evidence to support the suggestion that vCJD or in fact sporadic CJD ; has been acquired through receiving urinary gonadotrophins'. In our opinion, the available epidemiological data are reassuring, although they do not seem enough to guarantee gonadotrophin safety. We congratulate the authors for their work, and trust they will continue with their endeavour `continuing to collect data on a wide range of potential mechanisms of secondary transmission of CJD, including infertility treatment' Ward et al., 2004 ; .
