MATERIALS AND METHODS Organisms. A total of 3, 997 clinical isolates of Candida spp. obtained from more than 60 medical centers in Europe, Latin America, North America, and the Asia-Pacific region were collected during the course of the ARTEMIS Global Antifungal Surveillance Program in 2001 and 2002. The isolates represented consecutive incident isolates from patients with candidemia or other invasive forms of candidiasis isolates from sterile-site infections, tissue biopsy specimens, abscesses, and joint fluid ; cared for at ARTEMIS participating hospitals. Of the 3, 997 isolates, 15% 601 isolates ; were C. glabrata, including 331 isolates 20% of all Candida spp. submitted from North America ; from 21 study sites in North America, 58 isolates 8% of total submitted ; from 8 sites in Latin America, 135 isolates 14% of total submitted ; from 19 sites in Europe, and 77 isolates 11% of total submitted ; from 11 sites in the Asia-Pacific region. A total of 25 countries were represented in the collection. All isolates were identified by Vitek and API products bioMerieux, St. Louis, Mo. ; , supplemented by conventional methods as required 11 ; , and were stored as water suspensions until they were used. Prior to testing, each isolate was passaged on potato dextrose agar Remel, Lenexa, Kans. ; and CHROMagar Hardy Laboratories, Santa Monica, Calif. ; to ensure purity and viability. Antifungal agents. Standard antifungal powders of flucytosine Sigma ; , fluconazole Pfizer ; , voriconazole Pfizer ; , posaconazole Schering-Plough ; , ravuconazole Bristol-Myers Squibb ; , and caspofungin Merck ; were obtained from their respective manufacturers. Stock solutions were prepared in water caspofungin, fluconazole, and flucytosine ; , dimethyl sulfoxide ravuconazole and voriconazole ; , or polyethyleneglycol posaconazole ; . Serial twofold dilutions of each agent were prepared exactly as outlined in National Committee for Clinical Laboratory Standards NCCLS ; document M27-A2 18 ; . Final dilutions were However, there were no differences in the risk for all-cause readmission among patients discharged with a prescription for a thiazolidinedione HR 1.04, 95% CI 0.99 to 1.10; Table 2 ; or metformin HR 0.94, 95% CI 0.89 to 1.01; Table 3 ; compared with those not treated with an insulin sensitizer referent ; . However, there was a modestly higher risk of borderline statistical significance for readmission for heart failure among patients receiving a thiazolidinedione HR 1.06, 95% CI 1.00 to 1.12 ; and a lower risk for heart failure readmission with metformin HR 0.92, 95% CI 0.86 to 0.99 ; . Patients treated with both a thiazolidinedione and metformin had a significantly lower risk for readmission for all causes HR 0.82, 95% CI 0.69 to 0.96 ; and a borderline significantly lower risk for heart failure HR 0.85, 95% CI 0.71 to 1.01 ; . Readmissions for metabolic acidosis were similar among patients not treated with an insulin sensitizer 2.6% ; compared with those discharged with a prescription for metformin 2.3%, P 0.40 ; or a thiazolidinedione 2.2%, P 0.24.

MTL status, fluconazole, itraconazole, and flucytosine resistance, decade of isolation, and geographical source were not significant clade-related variables by ANOVA. DISCUSSION This study has generated a considerable amount of data on the population structure of isolates of C. albicans and the relationship between clades of isolates and their properties of clinical relevance. We have provided evidence that different clades of C. albicans may differ significantly in the proportions of isolates from blood, the oropharynx, the vagina, and other sites. While, on the one hand, it is beyond dispute that the immune status of the host is the major factor determining the ability of a C. albicans to invade human tissues 8, 28 ; , our data provide the first-ever clear suggestion that particular strain type clusters within the species may differ in their proportions of isolates from disseminated or mucosal infections. It is especially notable that, while the proportions of several properties of the isolates studied varied significantly between clades in single-factor tests, only ABC type and anatomical origin emerged as significant factors relating to clade number by univariate ANOVA. This result lends particular emphasis to the likely importance of an association between clades and putative virulence properties within the species of C. albicans. Assignation of population structures and clade boundaries to a set of isolates cannot be done entirely objectively. The clade assignments in Fig. 2 take account of three types of information: the UPGMA dendrogram, results of eBURST analysis, and the results of Ca3 oligonucleotide fingerprinting for several of the isolates. Use of neighbor-joining statistics in place of pairwise-difference analyses further redistributed some isolates between clades Fig. 3 ; . We intend to evaluate a wider range of statistical approaches to clade designation, including Bayesian statistics, when our database of MLST results is at least twice as large as that reported in this study. For the time being, we consider pairwise-difference analyses to be the simplest and most useful approach for clade assignments in the population of isolates at hand. The eBURST results were helpful in demarcating potential clades, but not definitive: many examples occurred where isolates that coclustered by Ca3 typing or by MLST analyzed by pair differences were designated as singletons by the eBURST test. It may be that the nature of sequence variation in C. albicans and the diploid genome of the species make eBURST analyses less relevant than they are to haploid bacteria 50 ; . In common with others 4 ; , we found an excellent correlation between UPGMA clusters for MLST and Ca3 fingerprinting data. Clades I, II, III, and SA as currently delimited by Ca3 typing 46 ; matched clades 1 to 4, respectively, as defined by MLST in the present study. Only MLST clade E failed to emerge as a single group of isolates as determined by MLST; the 5 representatives of Ca3 clade E split into two clusters by UPGMA analysis of MLST data Fig. 2 ; . The very clear demarcation of geographical origin of strains determined by Ca3 typing as described previously 46 ; was not confirmed in the present study. Our panel of isolates was dominated by isolates of European origin, particularly by isolates from the United Kingdom, while the panel of isolates studied by Ca3 typing 36, 46 ; was dominated by isolates from and flumist.

Dis. Soc. Am. ; . One of the possible reasons for the small number of published reports may be the lack of reliable methods for susceptibility testing of C. neoformans. Neither the NCCLS broth macrodilution reference method 16 ; nor the alternative broth microdilution method 13 ; recommended in the M27-A document has proved ideal for the detection of resistance to amphotericin B 15 ; . contrast, the E-test method, performed on glucose-supplemented RPMI 1640 agar, has provided an excellent means of discrimination between susceptible and resistant strains of C. neoformans 15 ; . Using this method, we found that there had been no change in the MIC ranges, MIC50s, or MIC90s of amphotericin B for C. neoformans between 1992 to 1994 and 1996 to 1998 Table 1 ; . Although the NCCLS M27-A document does not define MIC breakpoints for amphotericin B resistance, it has been suggested that isolates for which MICs are 2 g ml should be regarded as resistant. If this definition is adopted, our findings Table 1 ; indicate that less than 1% of C. neoformans isolates obtained between 1996 and 1998 were resistant to this agent. Although less than 2% of C. neoformans isolates are resistant to flucytosine prior to treatment 24 ; , a justified fear of the emergence of resistance during treatment with this drug alone and reports of favorable interactions in tests with C. neoformans in vitro and in vivo have led to its use in combination with amphotericin B in patients with cryptococcosis 22 ; . In this study, we found that there had been almost no change in the MIC ranges, MIC50s, and MIC90s of flucytosine for C. neoformans between 1992 to 1994 and 1996 to 1998 Table 1 ; . The NCCLS M27-A document 16 ; recommends that isolates for which MICs are 32 g ml regarded as resistant to flucytosine. By this definition, the rate of flucytosine resistance by C. neoformans ranged from 1.6% among isolates collected from 1992 to 1994 to 2.2% among those collected from 1996 to 1998. Various methods have been developed for testing the susceptibility of C. neoformans to azole antifungal agents, including fluconazole and itraconazole 2, 10, 12, ; . The NCCLS reference method 16 ; has proved problematic, as has Remune had no effect upon people with HIV and AIDS. The complaint further alleges defendants' false misrepresentations worked to artificially inflate the price of Immune stock." Visit wyca . ; The New York Times on July 9 reported that IRC shares dropped 44% the day of the Pfizer announcement, down .01 to .58. According to the report, IRC planned to continue its Remune trials, but with only enough money for about six months. Company executives told the Times that money from investors may be hard to come by following Pfizer's decision. HIV treatment advocate and longtime Remune supporter David Scondras, founder of Search for a Cure, in Boston, is struggling to either get Agouron to state a scientific reason for dropping out of the Remune trials, or to continue funding trials looking for another potential role for the therapy. These trials seek to determine whether using Remune during a Strategic Treatment Interruption STI ; can increase the amount of time that a person can be off drug and remain below a predetermined HIV viral load the amount of HIV in the blood ; . Scondras' own partner is in a clinical trial looking at this issue. According to Reuters Health news service, Agouron based its decision on data from several studies. The thought of a pharmaceutical company callously stopping a trial midway outraged many advocates. But Delaney claims that the truth is, the STIs trial were still in preliminary stages and have not actually started, and that the 10 people in Boston signed up have not yet been given Remune. Scondras says his partner did receive a Remune injection already. ; Delaney says one of the big dangers now would be a public perception that immune-based therapies--the stimulation of people's own immune system to fight HIV--don't work, rather than that Remune doesn't work. e and fluoride.

Activity of XR5944 against CCRF-CEM Cell Lines Using the ATP-TCA, the IC50 values for XR5944 were 0.27 F 0.05 and 4.24 F 0.25 nmol L in the CCRF-CEM parental and XR5944-resistant sublines, respectively. The quantitative PCR technique produced extremely reproducible results with an intra-assay and interassay coefficient of variation of 1.5% and 5%, respectively. The XR5944 line showed 10- and 100-fold increase in mRNA levels of major vault protein and MDR1 Fig. 1 ; , respectively, when compared with the parental line. Quantitative PCR also showed a modest increase in the expression of MRP1 2DDCt 2.0 ; . The levels of BCRP, MRP2, and topoisomerase isoforms were essentially unchanged in the resistant subline. Activity of XR5944 against Tumor-Derived Cells Each of the agents tested produced a wide range of tumor inhibition, as can be seen in Table 2. This is consistent with considerable heterogeneity of chemosensitivity as published previously 22 24 ; . XR5944 showed a steep concentration response curve in most tumors. Overall, XR5944 had median IC50 and IC90 values of 26 and 68 nmol L, respectively Table 2 ; . The IC90 values well correlated with the IC50 values r 0.8055; P 0.0001; nonparametric Spearman correlation ; . In all samples, XR5944 was more.
Effect of the partial enzyme activity of the Stop373C mutant protein. The nonclassic presentation of the patient was evident by normal genitalia, premature sexual hair growth and mild growth acceleration between the ages of 57 yr, normal PRA and aldosterone levels, low normal cortisol secretion, and only mildly elevated basal 5-17P level. It is of interest that the in vitro Stop373C enzyme exhibited a similar degree and fluphenazine. Received November 8, 1996.

Cuenca-Estrella et al. susceptibility of C. glabrata to fluconazole was noted over the 3 year period. Focusing on the results of our study it can be seen that, overall, non-albicans species were isolated more frequently than C. albicans. In the Spanish laboratory, 69.8% of episodes of candidaemia were caused by non-albicans species, and in the Argentinian laboratory, 59.1% of episodes. The rate of the incidence of C. parapsilosis fungaemia in both Spain and Argentina is interesting to note. Among Spanish isolates, C. parapsilosis was the most common pathogen 39.1% ; and among Argentinean isolates, the second most frequently isolated Candida spp. 30.4% ; . This organism is often a cause of clusters of nosocomial cases related to poor catheter care or poor infection control practices.3, 4 Compared with the incidence in other studies, it is remarkable that similar rates of C. parapsilosis were described in neonatal units included in the NEMIS programme and in Latin American medical centres in the SENTRY programme. In addition, a single US institution study has reported the emergence of C. parapsilosis as the predominant Candida species causing fungaemia in a children's hospital 49% of episodes ; , and an Italian study and a Brazilian multicentre study have reported a rate of nosocomial candidaemias caused by C. parapsilosis comparable to the values obtained in the present study.2628 These data support the hypothesis that geographical variation may have influenced the high incidence of C. parapsilosis fungaemia in some institutions, but whether true or not, given the rates of C. parapsilosis infection in Spanish and Argentinian medical centres, good catheter care and infection control practices should be implemented in both countries. The in vitro susceptibility results obtained for amphotericin B and flucytosine are consistent with other reports.8, 17, 22, 25 MICs of amphotericin B for the great majority of isolates 97.5% ; ranged from 0.12 to 1 mg L. In addition, 8.3% of strains had decreased susceptibility to flucytosine, a rate similar to those recorded by the SCOPE and SENTRY programmes and some European surveys.17, 25 Regarding susceptibility results for azole agents, as others have reported, 8, 24 the percentages of fluconazole- and itraconazole-resistant organisms causing candidaemia were low, 3.5% and 6.6%, respectively. However, the rates of decreased susceptibility to azole agents category including dose-dependently susceptible and resistant organisms ; were significantly higher. Overall, the percentages of decreased susceptibility to fluconazole and itraconazole were 9.9% and 21.9%, respectively. On the other hand, our data indicated that although the rates of resistance to azole agents are low, there were regional differences in resistance to these agents when results were analysed by species. Decreased susceptibility to azole agents was detected more frequently among Argentinian isolates of C. albicans, C. parapsilosis and C. tropicalis. The explanation for this resistance trend is unknown. These findings reinforce the need for active surveillance programmes that analyse multiple factors such as patient population, hospital infection control practices, antifungal and antimicrobial therapies, cytotoxic treatments and underlying diseases. Finally, the reproducibility of the susceptibility results using the EUCAST procedure was very high. A high correlation was observed between MICs for quality control strains obtained in Spain and Argentinian laboratories ICC 0.97 ; , indicating that the EUCAST methodology is a reliable technique that gives good interlaboratory agreement. In addition, the MICs determined by the EUCAST method show a good agreement with the NCCLS reference MICs for quality control strains and flurazepam.
