[Diagnosis and management of fungal infections and pneumocystis pneumonitis in pediatric cancer patients].
Invasive fungal infections are important causes of morbidity and mortality in pediatric cancer patients with hematological malignancies and following allogeneic hematopoietic stem cell transplantation. This article provides the recommendations of the Infectious Diseases Working Party of the German Society for Pediatric Infectious Diseases (DGPI) and the German Society for Pediatric Hematology/Oncology (GPOH) for diagnosis and treatment of fungal infections including Pneumocystis jiroveci. They are based on specific pediatric pharmacological and regulatory considerations and on the results of clinical trials, case series and expert opinions using the evidence criteria set forth by the Infectious Diseases Society of America (IDSA). Recommendations for the most frequent clinical entities are summarized here. Options for initial therapy of uncomplicated candidemia include deoxycholate amphotericin B (DAMB), fluconazole (FLC), liposomal amphotericin B (LAMB), the combination of DAMB plus FLC as well as voriconazole (VCZ) for patients > 11 years. For acute disseminated candidiasis, the combination of DAMB plus flucytosine is recommended. Indwelling central venous catheters serve as infectious nidus and should be removed whenever feasible. First-line therapy for presumed or proven invasive Aspergillus infections in patients 12 years and older is VCZ with DAMB and LAMB serving as alternatives. Choices for patients < 12 years of age are essentially limited to DAMB and LAMB. Due to the yet lacking evidence for enhanced antifungal efficacy and the ongoing dosage finding of caspofungin (CAS) in pediatric patients, combination therapies (LAMB plus CAS or VCZ plus CAS) should only be considered for fulminant or massive, life threatening infections. In granulocytopenic patients, adjunctive therapy with colony-stimulating factors (G-CSF) is recommended. In patients under immunosuppressive therapy, glucocorticosteroids ought to be reduced or discontinued, if feasible. Surgical interventions are restricted to specific indications. Zygomyces infections are an indication for high-dose LAMB. The combination of DAMB plus flucytosine is the initial treatment of choice of cryptococcal mengoencephalitis, and for treatment of Pneumocystis jiroveci pneumonitis, trimethoprim/sulfamethoxazol or intravenous pentamidine is recommended. Beyond the listed entities, the article provides a brief review on the pharmacokinetics and dosing of antifungal agents in children and adolescents as well as detailed discussions and evidence-based recommendations for empirical antifungal therapy, diagnosis and treatment of superficial fungal infections, of invasive infections by previously rare fungal pathogens and endemic moulds and for adjunctive immunomodulatory and surgical interventions.

[Antimicrobial agents in pediatric cancer patients with hepatic or renal impairment].
Antimicrobial agents are among the most frequently prescribed therapeutics in the supportive care of children and adolescents with cancer or following hematopoietic stem cell transplantation. Most of these agents are cleared from the body by elimination of unchanged drug by the kidney and/or metabolism by the liver. Impaired renal and hepatic function may have profound effects on the pharmacokinetics and pharmacodynamics of antimicrobial agents, necessitating modification of the dosage regimen in order to avoid toxicity through accumulation of the parent and/or its metabolites. Key to minimize such toxicities is a thorough understanding of the antimicrobial drug armamentarium and a careful evaluation of benefits and risks of antimicrobial interventions. This article reviews the mechanisms of renal and hepatic drug clearance in the normal state and in the state of functional impairment, their implications for antimicrobial therapy and dosage recommendations for pediatric cancer patients with impaired renal or hepatic function.

[Drug interactions of antimicrobial agents in children with cancer].
Antimicrobial agents are among the most common therapeutics prescribed to children and adolescents with hematologic/oncologic disorders. Because of the polymorbid state of most patients, they are frequently administered concomitantly with other drugs, resulting in a considerable potential for drug interactions. While many of these interactions are of marginal clinical significance, others are associated with substantial risks of decreased therapeutic efficacy or increased drug toxicity. Prevention and recognition of drug interactions are therefore of vital importance to optimizing effective use of antimicrobials and enhancing patient outcome. Key to minimize drug interactions are a thorough understanding of the pharmacology of frequently used antimicrobial agents and a careful evaluation of risks and benefits of potentially interacting drugs. This article reviews mechanisms and clinical relevance of drug interactions of antimicrobial agents in the supportive care of children and adolescents with hematologic/oncologic disorders and provides strategies for their prevention.

[Viral infections in pediatric cancer patients].
Children with cancer or stem cell transplantation (SCT) are at considerable risk to develop life threatening viral infections. Due to both underlying disease and immunosuppressive therapy lymphocyte number and function are low and the cellular immunity against viral infections is restricted or missing. As immunosuppressive treatment regimens and mismatched or T-cell-depleted stem cell products are being used increasingly, viral infections will become an even greater problem in the future. PCR-based methods have become an indispensable tool for early recognition, preemptive therapy, and monitoring therapeutic responses by qualitative and quantitative approaches. Assays are now available that allow for parallel screening of the 16 most common viral agents. Responses to antiviral therapy are often limited in immunocompromised patients and mainly depend on the time of their initiation. Most antiviral agents have a toxicity profile that may become clinically relevant and curtail antiviral therapy. New options for treatment are therefore warranted. For the next future, these may include the transfer of specific T-cells and other immunotherapeutic approaches. This article provides the recommendations of the Infectious Diseases Working Party of the German Society for Pediatric Hematology/Oncology (GPOH) and the German Society for Pediatric Infectious Diseases (DGPI) for diagnosis and treatment of viral infections in children with cancer or post HSCT. They are based on the results of clinical trials, case series and expert opinions using the evidence criteria set forth by the Infectious Diseases Society of America (IDSA).

Antifungal agents: in vitro susceptibility testing, pharmacodynamics, and prospects for combination therapy.
As invasive fungal infections in immunocompromised patients become increasingly important, the field of antifungal chemotherapy continues to evolve rapidly. New agents have entered the clinical arena, providing physicians with a variety of choices for treatment of most infections. Standardized methods for testing the in vitro susceptibility of fungi have become available, and concentration-effect relationships are increasingly explored. Finally, the availability of an entirely new class of antifungal agents is opening new opportunities for combination therapy of infections that are notoriously difficult to treat and carry a dismal prognosis. However, the ongoing progress in these key areas has also made antifungal chemotherapy considerably more complex and susceptible to misconceptions. Continuing efforts in the laboratory and well designed collaborative clinical trials are needed more than ever to turn opportunities into lasting benefit for patients at risk for or suffering from life-threatening invasive mycoses.

Itraconazole--perspectives for the management of invasive aspergillosis.
Itraconazole has become an important option in the management of invasive aspergillosis. The compound has potent and broad spectrum antifungal activity in vitro against Aspergillus spp. with a species- and strain dependent fungicidal mode of action. In vivo, the antifungal efficacy of itraconazole has been demonstrated in several non-immunocompromised and immunocompromised animal models of disseminated and invasive pulmonary aspergillosis. Itraconazole is available in oral and intravenous formulations, displays non-linear plasma pharmacokinetics, and is usually well tolerated. Non-comparative clinical data of itraconazole for therapy of suspected or proven invasive aspergillosis suggest response rates similar to those of conventional amphotericin B; however, the experience with itraconazole for induction therapy of invasive aspergillosis is limited, particularly in profoundly neutropenic patients. Itraconazole has an important role for consolidation and maintenance therapy of patients with invasive aspergillosis, and novel combination therapies involving itraconazole are currently under intensive preclinical investigation as to their usefulness for primary therapy.

[Guidelines for Prevention of Pneumocystis carinii Pneumonitis in Children and Adolescents with Cancer].
Pneumocystis carinii pneumonitis (PCP) is one of the most important opportunistic infections in children and adolescents with cancer. Its high frequency and a considerable mortality have led to primary chemoprophylaxis in patients with hematological malignancies and following allogeneic hematopoietic stem cell transplantation. Although less well characterized, patients with autologous stem cell transplantation and patients with dose-intensive chemotherapy for pediatric solid tumors may have a similarly high risk for PCP based on their profound T-cell depletion. For more than two decades, effective chemoprophylaxis for PCP has been available. Trimethoprim and sulfamethoxazole (TMP/SMX) is the prophylactic modality of first choice. The combination has been shown to be almost 100 % efficacious in pediatric cancer patients at highest risk, and it is usually well tolerated in this setting. Secondary alternatives to TMP/SMX include oral dapsone, oral atovaquone, and aerosolized pentamidine-isethionate. These modalities are less effective than TMP/SMX, and have been evaluated predominantly in HIV-infected patients. This article reviews epidemiology and current approaches to chemoprophylaxis for PCP in children and adolescents with cancer and/or hematopoietic stem cell transplantation, and provides evidence-based guidelines for indications and modalities of PCP prophylaxis in this population.

[Prevention of fungal infections in children and adolescents with cancer].
Opportunistic mycoses have emerged as important causes for morbidity and mortality in pediatric cancer patients, particularly in those with intensively treated hematological malignancies, allogeneic hematopoetic stem cell transplantation, and aplastic anemia. The incidence of invasive fungal infections in these settings may range from 10 to 25 % despite empirical antifungal therapy with an overall case fatality rate of up to 50 and 75 % depending on the organism. Preventive interventions are thus warranted, including but not limited to chemoprophylaxis with antifungal agents. Effective chemoprophylaxis of invasive Candida infections with a long-term benefit for overall survival has been demonstrated in patients with allogeneic bone marrow transplantation. However, its benefit in other high-risk populations is less well established, and a clearly effective approach to chemoprophylaxis for invasive Aspergillus infections has not been documented in appropriately designed clinical trials. This article reviews epidemiology and current approaches to chemoprophylaxis of opportunistic invasive fungal infections in children and adolescents with cancer and/or stem cell transplantation, and provides evidence-based guidelines for indications and modalities of antifungal prophylaxis and antifungal infection control measures in this population.

Uncommon opportunistic fungi: new nosocomial threats.
During the past two decades opportunistic fungal infections have emerged as important causes of morbidity and mortality in patients with severe underlying illnesses and compromised host defenses. While Aspergillus and Candida spp. collectively account for the majority of these infections, recent epidemiological trends indicate a shift towards infections by Aspergillus spp., nonalbicans Candida spp., as well as previously uncommon opportunistic fungi. Apart from an expanding number of different Zygomycetes, previously uncommon hyaline filamentous fungi (such as Fusarium species, Acremonium species, Paecilomyces species, Pseudallescheria boydii, and Scedosporium prolificans), dematiaceous filamentous fungi (such as Bipolaris species, Cladophialophora bantiana, Dactylaria gallopava, Exophiala species, and Alternaria species) and yeast-like pathogens (such as Trichosporon species, Blastoschizomyces capitatus, Malassezia species, Rhodotorula rubra and others) are increasingly encountered as causing life threatening invasive infections that are often refractory to conventional therapies. On the basis of past and current trends, the spectrum of fungal pathogens will continue to evolve in the settings of an expanding population of immunocompromised hosts, selective antifungal pressures, and shifting conditions in hospitals and the environment. An expanded and refined drug arsenal, further elucidation of pathogenesis and resistance mechanisms, establishment of in vitro/in vivo correlations, incorporation of pharmacodynamics, combination- and immunotherapies offer hope for substantial progress in prevention and treatment.

Pharmacokinetic and pharmacodynamic modeling of anidulafungin (LY303366): reappraisal of its efficacy in neutropenic animal models of opportunistic mycoses using optimal plasma sampling.
The compartmental pharmacokinetics of anidulafungin (VER-002; formerly LY303366) in plasma were characterized with normal rabbits, and the relationships between drug concentrations and antifungal efficacy were assessed in clinically applicable infection models in persistently neutropenic animals. At intravenous dosages ranging from 0.1 to 20 mg/kg of body weight, anidulafungin demonstrated linear plasma pharmacokinetics that fitted best to a three-compartment open pharmacokinetic model. Following administration over 7 days, the mean (+/- standard error of the mean) peak plasma concentration (C(max)) increased from 0.46 +/- 0.02 microg/ml at 0.1 mg/kg to 63.02 +/- 2.93 microg/ml at 20 mg/kg, and the mean area under the concentration-time curve from 0 h to infinity (AUC(0-infinity)) rose from 0.71 +/- 0.04 to 208.80 +/- 24.21 microg. h/ml. The mean apparent volume of distribution at steady state (V(ss)) ranged from 0.953 +/- 0.05 to 1.636 +/- 0.22 liter/kg (nonsignificant [NS]), and clearance ranged from 0.107 +/- 0.01 to 0.149 +/- 0.00 liter/kg/h (NS). Except for a significant prolongation of the terminal half-life and a trend toward an increased V(ss) at the higher end of the dosage range after multiple doses, no significant differences in pharmacokinetic parameters were noted in comparison to single-dose administration. Concentrations in tissue at trough after multiple dosing (0.1 to 10 mg/kg/day) were highest in lung and liver (0.85 +/- 0.16 to 32.64 +/- 2.03 and 0.32 +/- 0.05 to 43.76 +/- 1.62 microg/g, respectively), followed by spleen and kidney (0.24 +/- 0.65 to 21.74 +/- 1.86 and <0.20 to 16.92 +/- 0.56, respectively). Measurable concentrations in brain tissue were found at dosages of > or =0.5 mg/kg (0.24 +/- 0.02 to 3.90 +/- 0.25). Implementation of optimal plasma sampling in persistently neutropenic rabbit infection models of disseminated candidiasis and pulmonary aspergillosis based on the Bayesian approach and model parameters from normal animals as priors revealed a significantly slower clearance (P < 0.05 for all dosage groups) with a trend toward higher AUC(0-24) values, higher plasma concentrations at the end of the dosing interval, and a smaller volume of distribution (P < 0.05 to 0.193 for the various comparisons among dosage groups). Pharmacodynamic modeling using the residual fungal tissue burden in the main target sites as the primary endpoint and C(max), AUC(0-24), time during the dosing interval of 24 h with plasma drug concentration equaling or exceeding the MIC or the minimum fungicidal concentration for the isolate, and tissue concentrations as pharmacodynamic parameters showed predictable pharmacokinetic-pharmacodynamic relationships in experimental disseminated candidiasis that fitted well with an inhibitory sigmoid maximum effect pharmacodynamic model (r(2), 0.492 to 0.819). However, no concentration-effect relationships were observed in experimental pulmonary aspergillosis using the residual fungal burden in lung tissue and survival as parameters of antifungal efficacy. Implementation of optimal plasma sampling in discriminative animal models of invasive fungal infections and pharmacodynamic modeling is a novel approach that holds promise of improving and accelerating our understanding of the action of antifungal compounds in vivo.

Compartmental pharmacokinetics and tissue distribution of the antifungal echinocandin lipopeptide micafungin (FK463) in rabbits.
The plasma pharmacokinetics and tissue distribution of the novel antifungal echinocandin-like lipopeptide micafungin (FK463) were investigated in healthy rabbits. Cohorts of three animals each received micafungin at 0.5, 1, and 2 mg/kg of body weight intravenously once daily for a total of 8 days. Serial plasma samples were collected on days 1 and 7, and tissue samples were obtained 30 min after the eighth dose. Drug concentrations were determined by validated high-performance liquid chromatographic methods. Plasma drug concentration data were fit to a two-compartment pharmacokinetic model, and pharmacokinetic parameters were estimated using weighted nonlinear least-square regression analysis. Micafungin demonstrated linear plasma pharmacokinetics without changes in total clearance and dose-normalized area under the concentration-time curve from 0 h to infinity. After administration of single doses to the rabbits, mean peak plasma drug concentrations ranged from 7.62 microg/ml at 0.5 mg/kg to 16.8 microg/ml at 2 mg/kg, the area under the concentration-time curve from 0 to 24 h ranged from 5.66 to 21.79 microg x h/ml, the apparent volume of distribution at steady state ranged from 0.296 to 0.343 liter/kg, and the elimination half-life ranged from 2.97 to 3.20 h, respectively. No significant changes in pharmacokinetic parameters and no accumulation was noted after multiple dosing. Mean tissue micafungin concentrations 30 min after the last of eight daily doses were highest in the lung (2.26 to 11.76 microg/g), liver (2.05 to 8.82 microg/g), spleen (1.87 to 9.05 microg/g), and kidney (1.40 to 6.12 microg/g). While micafungin was not detectable in cerebrospinal fluid, the concentration in brain tissue ranged from 0.08 to 0.18 microg/g. These findings indicate linear disposition of micafungin at dosages of 0.5 to 2 mg/kg and achievement of potentially therapeutic drug concentrations in plasma and tissues that are common sites of invasive fungal infections.

Dosage-dependent antifungal efficacy of V-echinocandin (LY303366) against experimental fluconazole-resistant oropharyngeal and esophageal candidiasis.
V-echinocandin (VER-002; LY303366) is a semisynthetic derivative of echinocandin B and a potent inhibitor of fungal (1, 3)-beta-D-glucan synthase. We studied the antifungal efficacy, the concentrations in saliva and tissue, and the safety of VER-002 at escalating dosages against experimental oropharyngeal and esophageal candidiasis caused by fluconazole-resistant Candida albicans in immunocompromised rabbits. Study groups consisted of untreated controls, animals treated with VER-002 at 1, 2.5, and 5 mg/kg of body weight/day intravenously (i.v.), animals treated with fluconazole at 2 mg/kg/day i.v., or animals treated with amphotericin B at 0.3 mg/kg/day. VER-002-treated animals showed a significant dosage-dependent clearance of C. albicans from the tongue, oropharynx, esophagus, stomach, and duodenum in comparison to that for untreated controls. VER-002 also was superior to amphotericin B and fluconazole in clearing the organism from all sites studied. These in vivo findings are consistent with the results of in vitro time-kill assays, which demonstrated that VER-002 has concentration-dependent fungicidal activity. Esophageal tissue VER-002 concentrations were dosage proportional and exceeded the MIC at all dosages. Echinocandin concentrations in saliva were greater than or equal to the MICs at all dosages. There was no elevation of serum hepatic transaminase, alkaline phosphatase, bilirubin, potassium, or creatinine levels in VER-002-treated rabbits. In summary, the echinocandin VER-002 was well tolerated, penetrated the esophagus and salivary glands, and demonstrated dosage-dependent antifungal activity against fluconazole-resistant esophageal candidiasis in immunocompromised rabbits.

Compartmental pharmacokinetics of the antifungal echinocandin caspofungin (MK-0991) in rabbits.
The pharmacokinetics of the antifungal echinocandin-lipopeptide caspofungin (MK-0991) in plasma were studied in groups of three healthy rabbits after single and multiple daily intravenous administration of doses of 1, 3, and 6 mg/kg of body weight. Concentrations were measured by a validated high-performance liquid chromatography method and fitted into a three-compartment open pharmacokinetic model. Across the investigated dosage range, caspofungin displayed dose-independent pharmacokinetics. Following administration over 7 days, the mean peak concentration in plasma (C(max)) +/- standard error of the mean increased from 16.01 +/- 0.61 microg/ml at the 1-mg/kg dose to 105.52 +/- 8.92 microg/ml at the 6-mg/kg dose; the mean area under the curve from 0 h to infinity rose from 13.15 +/- 2.37 to 158.43 +/- 15.58 microg. h/ml, respectively. The mean apparent volume of distribution at steady state (Vd(ss)) was 0.299 +/- 0.011 liter/kg at the 1-mg/kg dose and 0.351 +/- 0.016 liter/kg at the 6-mg/kg dose (not significant [NS]). Clearance (CL) ranged from 0.086 +/- 0.017 liter/kg/h at the 1-mg/kg dose to 0.043 +/- 0.004 liter/kg/h at the 6-mg/kg dose (NS), and the mean terminal half-life was between 30 and 34 h (NS). Except for a trend towards an increased Vd(ss), there were no significant differences in pharmacokinetic parameters in comparison to those after single-dose administration. Caspofungin was well tolerated, displayed linear pharmacokinetics that fit into a three-compartment pharmacokinetic model, and achieved sustained concentrations in plasma that were multiple times in excess of reported MICs for susceptible opportunistic fungi.

Antifungal activity and pharmacokinetics of posaconazole (SCH 56592) in treatment and prevention of experimental invasive pulmonary aspergillosis: correlation with galactomannan antigenemia.
The antifungal efficacy, safety, and pharmacokinetics of posaconazole (SCH 56592) (POC) were investigated in treatment and prophylaxis of primary pulmonary aspergillosis due to Aspergillus fumigatus in persistently neutropenic rabbits. Antifungal therapy consisted of POC at 2, 6, and 20 mg/kg of body weight per os; itraconazole (ITC) at 2, 6, and 20 mg/kg per os; or amphotericin B (AMB) at 1 mg/kg intravenously. Rabbits treated with POC showed a significant improvement in survival and significant reductions in pulmonary infarct scores, total lung weights, numbers of pulmonary CFU per gram, numbers of computerized-tomography-monitored pulmonary lesions, and levels of galactomannan antigenemia. AMB and POC had comparable therapeutic efficacies by all parameters. By comparison, animals treated with ITC had no significant changes in outcome variables in comparison to those of untreated controls (UC). Rabbits receiving prophylactic POC at all dosages showed a significant reduction in infarct scores, total lung weights, and organism clearance from lung tissue in comparison to results for UC (P < 0.01). There was dosage-dependent microbiological clearance of A. fumigatus from lung tissue in response to POC. Serum creatinine levels were greater (P < 0.01) in AMB-treated animals than in UC and POC- or ITC-treated rabbits. There was no elevation of serum hepatic transaminase levels in POC- or ITC-treated rabbits. The pharmacokinetics of POC and ITC in plasma demonstrated dose dependency after multiple dosing. The 2-, 6-, and 20-mg/kg dosages of POC maintained plasma drug levels above the MICs for the entire 24-h dosing interval. In summary, POC at > or =6 mg/kg/day per os generated sustained concentrations in plasma of > or =1 microg/ml that were as effective in the treatment and prevention of invasive pulmonary aspergillosis as AMB at 1 mg/kg/day and more effective than cyclodextrin ITC at > or =6 mg/kg/day per os in persistently neutropenic rabbits.

Caspofungin: pharmacology, safety and therapeutic potential in superficial and invasive fungal infections.
Invasive fungal infections are important causes of morbidity and mortality in hospitalised patients. Current therapy with amphotericin B and antifungal triazoles has overlapping targets and is limited by toxicity and resistance. The echinocandin lipopeptide caspofungin is the first of a new class of antifungal compounds that inhibit the synthesis of 1,3-beta-D-glucan. This homopolysaccharide is a major component of the cell wall of many pathogenic fungi and yet is absent in mammalian cells. It provides osmotic stability and is important for cell growth and cell division. In vitro, caspofungin has broad-spectrum antifungal activity against Candida and Aspergillus spp. without cross-resistance to existing agents. The compound exerts prolonged post-antifungal effects and fungicidal activity against Candida spp. and causes severe damage of Aspergillus fumigatus at the sites of hyphal growth. Animal models have demonstrated efficacy against disseminated candidiasis and disseminated and pulmonary aspergillosis, both in normal and in immunocompromised animals. Caspofungin possesses favourable pharmacokinetic properties and is not metabolised through the cytochrome P450 (CYP) enzyme system. It showed highly promising antifungal efficacy in Phase II and III clinical trials in immunocompromised patients with oesophageal candidiasis. Caspofungin was effective in patients with invasive aspergillosis intolerant or refractory to standard therapies. Based on its documented antifungal efficacy and an excellent safety profile, caspofungin has been approved recently by the US Food and Drug Administration for the treatment of invasive aspergillosis in patients who are refractory to or intolerant of other therapies (i.e., amphotericin B, lipid formulations of amphotericin B, and/or itraconazole). Phase III clinical trials in patients with candidaemia and in persistently febrile neutropenic patients requiring empirical antifungal therapy are ongoing. This paper reviews the preclinical and clinical pharmacology of caspofungin and its potential role for treatment of invasive and superficial fungal infections in patients.

Antifungal pharmacodynamics: concentration-effect relationships in vitro and in vivo.
The pharmacodynamics of antifungal compounds involve relationships among drug concentrations, time, and antimicrobial effects in vitro and in vivo. Beyond better understanding of a drug's mode of action, characterization of these relationships has important implications for setting susceptibility breakpoints, establishing rational dosing regimens, and facilitating drug development. Important advances have been made in the experimental investigation of pharmacokinetics and pharmacodynamics of antifungal drugs; however, much remains to be learned about specific pathogens and specific sites of infection. Increased incorporation of pharmacokinetic and pharmacodynamic principles in experimental and clinical studies with antifungal agents is an important objective that will benefit the treatment and prophylaxis of life-threatening invasive fungal infections in immunocompromised patients.
