Fluconazole and flucytosine have different mechanisms of action. Since fluconazole has not been associated with hematologic suppression and does not produce renal impairment that can result in higher serum flucytosine levels, this combination may be better tolerated than is amphotericin B plus flucytosine.. Patients in each cohort receive a lower dose of fluconazole alone or in combination with flucytosine, or a higher dose of fluconazole alone. Doses in subsequent cohorts are escalated if safety data in the previous cohort is satisfactory. Patients are evaluated weekly for the first 4 weeks and every 2 weeks thereafter. Therapy continues until 8 weeks after the CSF becomes culture negative, up to a maximum of 26 weeks. ...
Candida tropicalis is a diploid ascomycetes yeast responsible for 4%-24% of candidemia. Resistance to flucytosine is rarely described for this species but was observed for 45 (35%) of 130 C. tropicalis isolates recovered from blood cultures in the Paris area in a 4-year survey. The aims of this study were to test the hypothesis that the flucytosine-resistant isolates could represent a subgroup and to determine the relationship between epidemiologic and genomic data. Epidemiologic data and gene sequences were analyzed, and molecular typing was performed. Our results suggest that a clone of flucytosine-resistant isolates, associated with malignancies and a lower mortality than that for other C. tropicalis isolates, is widespread in the Paris area. We propose the analysis of 2 polymorphic microsatellite markers coupled with URA3 sequencing to track the clone.

At least 10 percent of patients with a low CD4 count and HIV infection will develop meningitis due to Cryptococcus neoformans. More effective treatments than the standard therapy need to be explored.. Patients are selected by a randomization process to take amphotericin B intravenously (in the vein), for 14 days, and either placebo (ineffective substance) or flucytosine for 14 days. Then patients are again selected by a randomization process to take either (1) fluconazole for a total of 8 weeks plus itraconazole placebo; or (2) itraconazole for a total of 8 weeks plus fluconazole placebo. ...
A replication-competent oncolytic adenovirus encoding the murine pro-inflammatory cytokine interleukin-12 (IL-12) gene and two suicide fusion genes, a yeast cytosine deaminase (yCD) and a mutant form of herpes simplex virus type 1 thymidine kinase (HSV-1 TKSR39), with potential immunomodulating and antineoplastic activities. Upon intratumoral administration of Ad5-yCD/mutTKSR39rep-hIL12, the adenovirus selectively infects and replicates in tumor cells, which results in direct tumor cell lysis.

Both these studies also demonstrated that, with appropriate monitoring, conventional amphotericin B is reasonably well tolerated, with drug discontinuations in 3% of patients in the first 2 weeks in the Mycoses Study Group trial [21]. Saline and fluid loading equivalent to 1 litre normal saline daily should be given unless contraindicated, to minimize nephrotoxicity [63], and electrolytes replaced as required. Anaemia, secondary to suppression of erythropoietin transcription [64], is also a predictable side effect of amphotericin B [65-67]. This may be more clinically significant in populations with lower baseline haemoglobin levels, and where transfusion, when occasionally needed, is difficult.. Flucytosine, at the historically low daily dose of 100 mg/kg, was also well tolerated without real-time drug level monitoring in either trial. A substudy of the Thai trial comparing oral and intravenous flucytosine at the same daily dosage of 100 mg/kg has provided some insight into this observation. In ...
Toca 511 and Toca FC is a combination drug involving a gene therapy agent and a prodrug. It is a candidate drug to treat brain cancers. Toca 511 (vocimagene amiretrorepvec) is a gene therapy agent, wherein the payload is a gene encoding cytosine deaminase (CD) in a replicating, non-lytic retroviral vector. Toca FC is an extended-release formulation of the antifungal drug, 5-fluorocytosine, which is a prodrug of 5-fluorouracil, a known cancer drug. 5-fluorouracil does not cross the blood-brain barrier well, but 5-fluorocytosine does. The combination drug was designed to be used after a brain tumor is removed surgically; Toca 511 is intended to be injected into the tissues lining the hole where the tumor was (this region is called the margin), where the virus replicates only in cells that are dividing - in other words, cancer cells left over in the margin and immune cells that are present. 5-fluorocytosine is then administered to the person, and is converted to 5-fluorouracil in those cells by CD ...

In the Jaffe reaction, creatinine reacts with picric acid to form a colored complex. This forms the basis for the commonest methods for measuring serum creatinine. However, this test has well known limitations. Under normal circumstances, the Jaffe reaction overestimates the serum creatinine concentration by 10-20% because of the presence of endogenous chromogens. These chromogens include acetone and acetoacetate which, in the case of diabetic ketoacidosis, can lead to a significant overestimation of the serum creatinine. Similarly, certain drugs, including cephalosporins, flucytosine and barbiturates, can interfere with the assay ...

The therapy for cryptococcal meningitis in patients with the acquired immunodeficiency syndrome (AIDS) is still unsatisfactory. Although other populations generally respond well to treatment with amphotericin B and flucytosine, patients with AIDS have a markedly lower cure rate (1). Moreover, after the initial therapy, long-term maintenance treatment with an antifungal agent is mandatory, because of the high frequency of recurrences. Weekly amphotericin B therapy has been recommended for this purpose, but Zuger and colleagues (2) show that some patients have relapses despite the administration of maintenance doses of the drug. On the other hand, the severity of side effects (including ...

A synthetic bioredox system for the oxidative decarboxylation of L-malate to pyruvate was presented, with which the enzyme purification steps can be omitted. The bioredox system consisted of ME-t (mutant malic enzyme ME L310R/Q401C) and non-natural coenzyme nicotinamide flucytosine dinucleotide (NFCD+) catalyzes the oxidation of L-malate to pyruvate and concurrently generates the reduced coenzyme, NFCDH. Escherichia coli BL21(DE3) pET24b-ME-t cell lysates catalyze the oxidation of L-malate and produce pyruvate only, indicating that the cell lysates have the same substrate selectivity as the purified enzyme. NADH oxidase (NOX) from Enterococcus faecalis can oxidize NFCDH to regenerate NFCD+. Compared with the reaction system containing NAD(+), ME lysates, and NOX lysates, the system containing NFCD+, ME-t lysates, and NOX lysates converts L-malate to pyruvate in 9% higher yield and with significantly less lactate formation. These results suggest that the synthetic bioredox system composed of ME-t ...

CORRESPONDENCE. Responding to the evidence for improved treatment for cryptococcal meningitis in resource-limited settings. To the Editor: The World Health Organization (WHO) issued the first evidence-based treatment guidelines for cryptococcal meningitis in December 2011.1 Although its incidence has decreased with increased access to antiretroviral therapy, cryptococcal meningitis remains a major cause of death in people with HIV/AIDS, with over 500 000 deaths every year in sub-Saharan Africa. It is a leading cause of death in the Médecins sans Frontières (MSF) HIV/AIDS programmes in Africa.2,3. The preferred treatment in the WHO guidelines combines amphotericin B injectable with oral solid formulations of either flucytosine or fluconazole. The liposomal injectable form of amphotericin B is also indicated as an alternative to conventional amphotericin B because it is associated with fewer side-effects. However, it is acknowledged that this option is currently too expensive for routine use in ...
Efficacies of High-Dose Fluconazole plus Amphotericin B and High-Dose Fluconazole plus 5-Fluorocytosine versus Amphotericin B, Fluconazole, and 5-Fluorocytosine
The use of enzymes as biocatalysts applied to synthesis of modified nucleoside-5-monophosphates (NMPs) is an interesting alternative to traditional multistep chemical methods which offers several advantages, such as stereo, regio and enantioselectivity, simple downstream processing, and mild reaction conditions. Herein we report the recombinant expression, production and purification of uracil phosphoribosyltransferase from Thermus themophilus HB8 (TtUPRT). The structure of TtUPRT has been determined by protein crystallography, and its substrate specificity and biochemical characteristics have been analysed, providing new structural insights into the substrate-binding mode. Biochemical characterization of the recombinant protein indicates that the enzyme is a homotetramer, with activity and stability across a broad range of temperatures (50-80 °C), pH (5.5-9) and ionic strength (0-500 mM NaCl). Surprisingly, TtUPRT is able to recognize several 5 and 6-substituted pyrimidines as substrates. ...
BACKGROUND. Cryptococcal meningitis (CM) causes an estimated 180,000 deaths annually, predominantly in sub-Saharan Africa, where most patients receive fluconazole (FLC) monotherapy. While relapse after FLC monotherapy with resistant strains is frequently observed, the mechanisms and impact of emergence of FLC resistance in human CM are poorly understood. Heteroresistance (HetR) - a resistant subpopulation within a susceptible strain - is a recently described phenomenon in Cryptococcus neoformans (Cn) and Cryptococcus gattii (Cg), the significance of which has not previously been studied in humans. METHODS. A cohort of 20 patients with HIV-associated CM in Tanzania was prospectively observed during therapy with either FLC monotherapy or in combination with flucytosine (5FC). Total and resistant subpopulations of Cryptococcus spp. were quantified directly from patient cerebrospinal fluid (CSF). Stored isolates underwent whole genome sequencing and phenotypic characterization. RESULTS. ...
Purpose: Human neural stem cells (NSCs) are inherently tumor-tropic, making them attractive drug delivery vehicles. Toward this goal, we retrovirally transduced an immortalized, clonal NSC line to stably express cytosine deaminase (HB1.F3.CD.C21; CD-NSCs), which converts the prodrug 5-fluorocytosine (5-FC) to 5-fluorouracil (5-FU). Experimental Design: Recurrent high grade glioma patients underwent intracranial administration of CD-NSCs during tumor resection or biopsy. Four days later, patients began taking oral 5-FC every 6 hours for 7 days. Study treatment was given only once. A standard 3+3 dose escalation schema was used to increase doses of CD-NSCs from 10 million to 50 million and 5-FC from 75 to 150 mg/kg/day. Intracerebral microdialysis was performed to measure brain levels of 5-FC and 5-FU. Serial blood samples were obtained to assess systemic drug concentrations as well as to perform immunologic correlative studies. Results: Fifteen patients underwent study treatment. We saw no ...
1I5E: Structure of product-bound Bacillus caldolyticus uracil phosphoribosyltransferase confirms ordered sequential substrate binding.
PASLI disease is inherited in an autosomal dominant manner. This means one only needs a single abnormal gene from his/her parents to have PASLI disease. Of the two copies of PIK3CD each person carries, the abnormal PIK3CD gene dominates despite the fact that the matching PIK3CD gene from the other parent is normal. Additionally, dominant inheritance means most families with PASLI disease have affected relatives in each generation on the side of the family with the mutation. An alternative type of PIK3CD mutation is called de novo, which means that the mutation was not inherited from the parents but rather spontaneously arose in the patient. Children of a parent who carries a PIK3CD mutation have a 50% chance of inheriting the mutation. In a family, each childs risk of inheriting the mutated PIK3CD gene is independent of whether or not other siblings have the mutation. For example, if the first three children in a family have the mutation, the next child has the same 50% risk of inheriting the ...

Twenty-two patients with deep-seated mycotic infections were treated with 5-fluorocytosine: in 8 patients the infection was caused by species of Crypfococcus; in 8, Candida albicans; in 3, Phialophora species; in 1, Torulopsis glabrata; in 1, Sporothrix schenckii; and in 1, Aspergillus fumigatus. Apparent cure was achieved in 11 patients; 6 more showed significant improvement, but 5 were judged to be treatment failures. In some instances this new fungal antimetabolite was effective in cases that had not responded to amphotericin B. Because oral administration produces effective tissue levels, and side effects are rare and usually transient, this drug is a welcome addition to the therapeutic armamentarium for mycotic infections. It may become the drug of choice for the treatment of chromoblastomycosis. ...
