Flucytosine chromatogram

MATERIALS AND METHODS Animal protocol. Pathogen-free BALB c male mice, approximately 6 weeks of age and weighing 20 to 25 g, were used in all experiments. The animals were housed in isolation cages four per cage ; and were given free access to food and water. The mice were briefly anesthetized with CO2 narcosis, weighed individually, and challenged intracerebrally with approximately 300 CFU of Cryptococcus neoformans cells in a volume of 0.06 ml, which was delivered through a 27-gauge needle by direct puncture through the cranial vault approximately 6 mm posterior to the orbit. The animal protocol was approved by the University Institutional Animal Care and Use Committee. Chemotherapy. Mice were randomly assigned to treatment groups cages ; 48 h after intracerebral challenge, and treatment was initiated with the assigned concentrations of fluconazole and flucytosine dissolved in the sole source of drinking water. Drug concentrations were calculated on the basis of the weights of the animals in each treatment cage, measured daily water intake, and assigned drug doses. Treatment was continued for 11 days, with the water supply and added drugs changed every 4th day. The dose levels of fluconazole and flucytosine tested were from 0 to 40 body weight per day in 4- g g increments and from 0 to 200 g g day in 20- g g increments, respectively. In general, two cages with four animals each were treated at each dose combination tested. Mycologic procedures. The C. neoformans isolate was obtained from the laboratory of J. Richard Graybill isolate 89-127 ; and was maintained on Sabouraud dextrose agar at 4 C. the evening prior to infection of the mice, the isolate was grown on brain heart infusion agar at 37 C. The organisms were washed with normal pyrogen-free saline before suspension in saline. The concentrations of organisms injected into the mice were confirmed by serial 10-fold dilutions of the initial suspension and by counting the numbers of CFU on plates prepared from 0.06 ml of the suspension ejected from the inoculation syringe just before and after inoculation of the mice from each cage. For measurement of brain fungal burden, animals were sacrificed 24 h after cessation of treatment and the brains were removed, weighed, and homogenized in 2.0 ml of normal saline. Duplicate 10-fold serial dilutions of the whole brain homogenate were prepared for quantitative counts of CFU. A 0.1-ml aliquot from each dilution was plated on Sabouraud dextrose agar and incubated at 37 C for 72 to 96 h, and the numbers of CFU were recorded. For animals sacrificed to determine if the brain had become sterile, the entire brain homogenate was placed in a tube containing brain heart infusion broth, incubated at 37 C, and observed for 96 h to determine the presence or absence of growth. If growth was.

Secondary prophylaxis for cryptococcal meningitis in HIVinfected patients treated with highly active antiretroviral therapy Pacheco P, Ferreira L, Tavares L. Hospital de Santa Maria, Lisboa, Portugal An azole based drug regimen is recommended by currently accepted guidelines for prevention of opportunistic infections in HIV-infected patients as a lifelong secondary prophylaxis, after an episode of croptococcal meningitis. There is, however, some evidence that secondary prophylaxis could be safely discontinued in patients with certain opportunistic infections e.g. P. carinii and CMV ; after some CD4 + cell count increase under highly active antiretroviral therapy HAART ; . We present a microbiologically proven case of criptococcal meningitis in an HIV + , 29 year old, male IV drug abuser, successfully treated with a suppressive course of Amphotericin B three years ago. At the end of therapy induction, the CSF criptococcal antigen titier dropped from 1: 1000 to 64. In spite of a daily secondary prophylaxis with fluconazole 200mg id ; he was also treated with HAART lamivudine in combination with stavudine and indinavir ; for two years. Under this treatment the patient remained asymptomatic and a marked virologic response was obtained viral load drop from 4.79 to a sustained level around 2.7 log10 HIV RNA copies ML ; as well as a sustained immunological recovery from an initial CD4 + cell count of 9 to average of 230 CD4 + cell count l. The CD19 + cell counts, as marker of the B lymphocytes, remained also stable. During the last 52 weeks he stopped all treatments while resuming IV drug abuse. Now, while asymptomatic, an expected drop of CD4 + cell count to 80 and a viral load rise to 5.04log10 HIV RNA copies ml were observed. Currently he has a normal CSF with undetectable criptococcal antigen in CSF and blood. An absence of a criptococcal disease relapse during a 52-week period, while the patient had still CD4 + cell counts at least over 80 was observed. This case and the potential drugdrug often used to treat HIV-infected patients raise the question about the real value of criptococcal meningitis secondary prophylaxis and emphasizes the importance of a multicentric collaborative study of this issue.

In vivo activity of amphotericin B, itraconazole and terbinafine in a murine model of disseminated zygomycosis Dannaoui E1, Meis JF2, Verweij PE1. 1Department of Medical Microbiology, University Medical Center St. Radboud, Nijmegen, The Netherlands; 2Departement of Medical Microbiology, Canisius Wilhelmina Hospital, Nijmegen, The Netherlands Objectives: To evaluate the correlation between MICs determined in vitro and in vivo activity of amphotericin B AMB ; , itraconazole ITZ ; , and terbinafine TER ; in a murine model of disseminated zygomycosis. Methods: One isolate of Rhizopus microsporus and one isolate of Absidia corymbifera were tested. In vitro susceptibility testing was performed using an NCCLS-based microdilution technique M38-P ; . Nonimmunocompromised mice were infected intravenously with spore suspensions. Treatment was started 2h after infection and continued for ten days. ITZ and TER were given by gavage twice a day at 100 mg kg d and 150 mg kg d, respectively. AMB was given at 4.5 mg kg d by once intraperitoneal injection. Results: The MICs of AMB, ITZ and TER were 1, 32 and 0.5 g ml for Rhizopus microsporus and 0.12, and 0.25 for Absidia corymbifera, respectively. With the Rhizopus isolate, a lethal infection was obtained by day 5 to 8 for control mice receiving no active treatment. In comparision, there was 100% survival for mice receiving AMB. ITZ and TER did not prolonged survival compared to the controls. All control mice infected with Absidia died by day 8 to 9. AMB showed a good activity with 100% survival. TER did not prolonge survival compared to the controls, but ITZ was partially active with 40% survival at the end of the experiment. Conclusion: 1 ; AMB showed a good antifungal activity in vitro and in vivo against Rhizopus and Absidia. 2 ; A partial correlation between MICs and treatment outcome was seen with TER in this model.

Irreproducibility in antifungal susceptibility studies with pathogenic yeasts is a widely recognized problem 5-9, 15, 19, ; . Several environmental factors of which the most frequently cited are inoculum size, duration of incubation, and medium composition 2, 3, 5-9, ; , are known to influence the outcome of susceptibility tests in vitro. Incubation temperature is another variable that might influence antifungal MICs for yeasts in broth dilution tests, but the nature and extent of temperature effects differ for different authors. Most studies have shown minor or no differences in MICs of various antifungal agents tested against yeasts at temperatures ranging from 22 to 37C 1, 3, ; . However, Block et al. 2 ; noted a considerable increase in the susceptibility of Cryptococcus neoformans to flucytosine at 37C compared with that at 32C, while precisely the opposite effect of temperature was noted by Johnson et al., working with nystatin 14 ; , and Galgiani et al., working with flucytosine 11 ; , both in tests with Candida spp. An incubation temperature of 35C has emerged in some recent reports as preferable both to 37C 5 ; and to 30C 23, 25 ; for optimal reader agreement with visual MIC endpoints. Temperature was unequivocally a less significant factor influencing interlaboratory agreement between MICs than was the composition of the test medium 23 ; . In all of the reports cited, MIC was the susceptibility endpoint used to determine the effect of temperature, with one exception in which ion efflux in response to nystatin was measured with a K + electrode 14 ; . However, it has often been stressed that azole-derivative antifungal agents frequently cause partial inhibition of yeast growth at concentrations well below the MIC 1, 8, 12, ; . An MIC determination records only the point of complete growth inhibition and takes no account of the possible significance of measurable but incomplete inhibitory effects at lower drug concentrations. Several alternative susceptibility measurements that are based on non-MIC endpoints of an azole versus a yeast have been devised, for example, the 50% inhibitory concentration 10 ; , the relative area under the.

Flucytosine toxicity

Most HIV-infected patients initially develop HIVspecific immune responses comprising HIV-specific CD8 cell, CD4 cell and B cell activity. These responses are suboptimal and ultimately fail in the vast majority of patients, primarily because of viral mechanisms. The preservation of strong humoral and cellular HIV-specific immune responses in patients with non-progressive infection suggests that strategies to restore and maintain host immune responses will be important in the long-term management of patients with HIV disease. Effective HIV-specific immune responses will also be necessary for the success of prophylactic and therapeutic vaccine strategies. See Figure 2.4 and fludarabine.
