Abstract
Invasive pulmonary aspergillosis (IPA) is a severe condition in immunocompromised children, but the optimal management is still under debate. In order to better clarify this issue, a literature search was performed through MEDLINE/PubMed database to describe current risk factors and diagnostic, therapeutic and prophylactic tools for invasive pulmonary aspergillosis (IPA) in the paediatric age. Observational studies and clinical trials regarding diagnosis, treatment and prophylaxis were considered, and results were summarised. Five clinical trials and 25 observational studies (4453 patients) were included.Haematological malignancies, previous organ transplant and other primary or acquired immunodeficiency were identified as risk factors for IPA in children.Current diagnostic criteria distinguish between "proven", "probable" and "possible" disease. Consecutive galactomannan assays have good sensitivity and specificity, especially when performed on broncho-alveolar lavage. At the same time, β-D-glucan should not be used since cut-off in children is unclear. PCR assays cannot currently be recommended for routine use.Voriconazole is the recommended first-line agent for IPA in children older than 2 years of age. Liposomal amphotericin B is preferred in younger patients or cases of intolerance to voriconazole. Its plasma concentrations should be monitored throughout the treatment. The optimal duration of therapy has yet to be determined. Posaconazole is the preferred prophylactic agent in children older than 13 years old, whereas oral voriconazole or itraconazole are the drugs of choice for those between 2-12 years. Further good-quality studies are warranted to improve clinical practice.

Abstract
Posaconazole is often used for the prophylaxis and treatment of invasive fungal infections (IFI). However, intra- and inter-individual differences and drug interactions affect the efficacy and safety of posaconazole. Precision dosing of posaconazole based on the population pharmacokinetic (PopPK) model may assist in making significant clinical decisions. This review aimed to comprehensively summarize the published PopPK models of posaconazole and analyze covariates that significantly influence posaconazole exposure. Articles published until May 2022 for PopPK analysis of posaconazole were searched in PubMed and EMBASE databases. Demographic characteristics, model characteristics, and results of PopPK analysis were extracted from the selected articles. In addition, the steady-state pharmacokinetic profiles of posaconazole were simulated at different covariate levels and dosing regimens. Out of the 13 studies included in our review, nine studies included adults, three included children, and one included both adults and children. All oral administration models were one-compartment models, and all intravenous administration models were two-compartment models. Body weight, proton pump inhibitors, and incidence of diarrhea were found to be important covariates. Clinically, the potential impact of factors such as patient physiopathologic characteristics and comorbid medications on posaconazole pharmacokinetics should be considered. Dose adjustment in combination with TDM or replacement with a tablet or intravenous formulation with higher exposure may be an effective way to ensure drug efficacy as well as to reduce fungal resistance. Meanwhile, published models require further external evaluation to examine extrapolation.

Abstract
OBJECTIVE Prophylaxis with posaconazole (PP) is effective in the prevention of invasive fungal infections in immunocompromised adult patients. However, evaluation of its effectiveness and safety in children is limited. The aim of the study was to describe the use of posaconazole as antifungal prophylaxis in children. METHODS We reviewed the medical records of immunocompromised patients younger than 13 years with hematologic diseases and post hematopoietic stem cell transplant (HSCT) who received antifungal PP at the Instituto Nacional de Salud del Niño San Borja (INSN-SB) in Lima, Peru, from January 2014 to December 2018. RESULTS Fifty-six courses of PP were identified in 47 patients with a median age of 7.5 years (IQR, 4-10), 51.6% (n = 24) of whom were female. The main underlying medical conditions were aplastic anemia (n = 19, 33.9%), acute lymphoblastic leukemia (n = 18, 32.1%), acute myeloid leukemia (n = 14, 25.0%), and 34.1% had undergone HSCT. The median dose of posaconazole was 13.62 mg/kg/day (IQR, 12.0-16.8), and the median duration of PP was 24 days (IQR, 16-82). Gastrointestinal symptoms included abdominal pain (17.9%), nausea (16.1%), diarrhea (7.1%), and vomiting (3.6%). Elevated alanine aminotransferase and aspartate aminotransferase levels were observed in 9/35 patients (25.7%) and 10/51 (19.6%) patients, respectively. Five cases of breakthrough fungal infection were identified (8.9%). CONCLUSIONS Patients younger than 13 years who received PP showed an increase in transaminase values, and the development of breakthrough fungal infections.

Abstract
Antifungal prophylaxis can reduce morbidity and mortality from invasive fungal disease (IFD). However, its use needs to be optimised and appropriately targeted to patients at highest risk to derive the most benefit. In addition to established risks for IFD, considerable recent progress in the treatment of malignancies has resulted in the development of new 'at-risk' groups. The changing epidemiology of IFD and emergence of drug resistance continue to impact choice of prophylaxis, highlighting the importance of active surveillance and knowledge of local epidemiology. These guidelines aim to highlight emerging risk groups and review the evidence and limitations around new formulations of established agents and new antifungal drugs. It provides recommendations around use and choice of antifungal prophylaxis, discusses the potential impact of the changing epidemiology of IFD and emergence of drug resistance, and future directions for risk stratification to assist optimal management of highly vulnerable patients.

Abstract
Background Invasive fungal diseases (IFDs) are common and contribute to mortality in patients undergoing hematopoietic stem cell transplantation (HSCT). The relative efficacies of posaconazole (POS) and fluconazole (FLU) as primary antifungal prophylaxes are uncertain. Methods A retrospective study was performed on children treated with allogeneic HSCT who received POS or FLU during the early neutropenic period. The efficacies, safety, and tolerabilities of the prophylaxes were compared. Results Data on 78 HSCT recipients were analyzed. Most had thalassemia (58%). Pre-engraftment, POS and FLU were administered to 41 and 37 cases, respectively. There were no proven cases of IFD. However, 2 POS cases and 1 FLU case had probable IFDs. The IFD incidences of the POS (5%) and FLU (3%) groups demonstrated no statistical difference (p = 0.620). Of the 75 surviving cases receiving FLU post-engraftment (including 39 cases previously given POS), 3 had proven IFDs whereas 3 had probable IFDs (total, 6 [8%]) within 1 year post-HSCT. No cases discontinued the prophylaxes due to drug intolerance. The common adverse events with POS and FLU were not significantly different. Only 19% of the patients achieved the therapeutic POS level, with a starting dose of 4 mg/kg thrice daily. Conclusion POS and FLU demonstrate comparable levels of effectiveness, safety, and tolerability as IFD prophylaxes for neutropenic children treated with allogeneic HSCT. Determination of the optimum POS dose and duration requires larger studies.

Abstract
BACKGROUND Posaconazole is a broad-spectrum antifungal that is not licensed for use in children <13 years of age. Despite this and by necessity, it is used extensively in paediatric hospitals for prophylaxis of invasive fungal disease. OBJECTIVES To determine whether initial prophylactic dosing recommendations attain a posaconazole plasma concentration of ≥700 ng/mL in immunocompromised children <13 years of age. PATIENTS AND METHODS We performed a retrospective study of immunocompromised children <13 years of age receiving posaconazole suspension prophylaxis at a starting dose of 5 mg/kg every 8 h for ≥7 days and who had a posaconazole concentration measured after ≥7 days. Posaconazole plasma concentrations and rate of breakthrough infection were recorded. RESULTS A total of 70 patients were included with a median age of 5 years (range 3 months to 12 years). The mean posaconazole plasma concentration was 783.4 ng/mL (IQR 428.3-980 ng/mL) and the percentage of patients with a posaconazole plasma concentration ≥700ng/mL was 47.9%. Patients who were on a proton pump inhibitor, a histamine H2 antagonist or metoclopramide, had mucositis or were enterally fed had a lower posaconazole plasma concentration compared with patients without these co-administered drugs/mucositis/enteral feeding (542.3 versus 1069.8 ng/mL; P<0.001). The breakthrough invasive fungal infection rate was 4.3% (3/70). CONCLUSIONS The studied 5 mg/kg posaconazole suspension every 8 h resulted in target concentrations in only 47.9% of patients and further studies looking at newer posaconazole formulations are needed.

Abstract
BACKGROUND Posaconazole is a recommended option for antifungal prophylaxis in paediatric patients >12 years of age. However, little is known about plasma exposures and safety following administration of the delayed-release tablets (DRTs) in children and adolescents. METHODS In a retrospective observational study, we analysed steady-state trough concentrations of posaconazole in all paediatric patients who had received the DRT formulation between May 2015 and December 2018 for antifungal prophylaxis. Dosing was guided by a published population pharmacokinetic model with weight-based dosing. Drug concentrations in plasma were measured by a validated tandem MS method. Liver function and drug discontinuations due to adverse effects were also assessed. RESULTS A total of 34 patients (21 male, 13 female; median age 12 years, range 5-17 years; median body weight 43.5 kg, range 16-84 kg) undergoing treatment for haemato-oncological disorders (n=23) or immunosuppression for polyarthritis (n=1) or post-allogeneic HSCT (n=11) received posaconazole DRTs for a median of 70 days (range 9-391 days). The median first steady-state trough plasma concentration following model-derived dosing was 1607 ng/mL (range 501-8485 ng/mL) with trough concentrations being above the dosing target of ≥700 ng/mL in 32/34 patients (94%). Considering all (first and subsequent) trough concentrations, target attainment was 90% (63/70 samples). Posaconazole was well tolerated without adverse event-related discontinuations or breakthrough infections. CONCLUSIONS Administration of posaconazole DRTs to paediatric patients guided by a population pharmacokinetic-derived dosing algorithm resulted in predictable and potentially effective exposures and was well tolerated over prolonged time periods.

Itraconazole inhibits the Hedgehog signaling pathway thereby inducing autophagy-mediated apoptosis of colon cancer cells. Cell Death Dis 2020; 11:539.

Abstract
Itraconazole is as an antifungal medication used to treat systemic fungal infections. Recently, it has been reported to be effective in suppressing tumor growth by inhibiting the Hedgehog signaling pathway and angiogenesis. In the present study, we investigated whether itraconazole induces autophagy-mediated cell death of colon cancer cells through the Hedgehog signaling pathway. Cell apoptosis and cell cycle distribution of the colon cancer cell lines SW-480 and HCT-116 were detected by flow cytometry and terminal TUNEL assay. Autophagy and signal proteins were detected by western blotting and cell proliferation-associated antigen Ki-67 was measured using immunohistochemistry. The images of autophagy flux and formation of autophagosomes were observed by laser scanning confocal and/or transmission electron microscopy. Colon cancer cell xenograft mouse models were also established. Itraconazole treatment inhibited cell proliferation via G1 cell cycle arrest as well as autophagy-mediated apoptosis of SW-480 and HCT-116 colon cancer cells. In addition, the Hedgehog pathway was found to be involved in activation of itraconazole-mediated autophagy. After using the Hedgehog agonist recombinant human Sonic Hedgehog (rhshh), itraconazole could counteract the activation of rhshh. Moreover, treatment with itraconazole produced significant cancer inhibition in HCT-116-bearing mice. Thus, itraconazole may be a potential and effective therapy for the treatment of colon cancer.

Abstract
Background Diagnostic value of β-d-glucan (BDG) in populations with low prevalence of invasive fungal infection (IFI), such as hematologic patients receiving antimold prophylaxis, should be re-evaluated. Methods We retrospectively reviewed episodes with BDG results in hematologic patients receiving antimold prophylaxis from January 2017 to August 2019 in a tertiary hospital. The episodes were classified as true positive ([TP] positive BDG with IFI), true negative ([TN] negative BDG without IFI), false positive ([FP] positive BDG without IFI), false negative ([FN] negative BDG with IFI), and nonevaluable. Results A total of 203 episodes were analyzed: 101 episodes (49.8%) were from stem cell transplants, 89 (43.8%) were from induction chemotherapy, and 13 (6.4%) were from graft-versus-host disease treatment. There were 62 nonevaluable episodes. Among 141 evaluable ones, there were 8 (5.7%) episodes of probable/proven IFI. True positive, TN, FP, and FN cases were 4 (2.8%), 112 (79.4%), 21 (14.9%), and 4 (2.8%) episodes, respectively. Sensitivity, specificity, positive predictive value, and negative predictive value were 50.0%, 84.2%, 16.1%, and 96.5%, respectively. Positive predictive value was 26.7% and 0.0% in diagnostic and surveillance episodes, respectively. Conclusions β-d-glucan test should be used to exclude IFI rather than for diagnosis in these patients.

Abstract
OBJECTIVES Posaconazole is effective in preventing invasive fungal infections in neutropenic pediatric patients. The oral suspension has challenges in administration and absorption that are theorized to be minimized with delayed release tablets. However, this has not been validated in the pediatric population. This study was conducted to compare the efficacy and safety of posaconazole suspension and delayed release tablets in pediatric hematology/oncology patients. METHODS A retrospective chart review in pediatric hematology/oncology patients was conducted from February 2013 to February 2017. Data collected include patient demographic data; posaconazole formulation, dose, and serum concentrations; and adverse events. RESULTS Sixty-five patients with 353 serum posaconazole concentrations were included; 51.6% of concentrations drawn while patients were receiving posaconazole suspension were therapeutic, whereas 62.5% of concentrations drawn while patients were receiving posaconazole delayed release tablets were therapeutic (p = 0.035). Serum concentrations drawn while taking acid suppression (histamine receptor antagonists or proton pump inhibitors) and posaconazole suspension were less likely to be therapeutic (p < 0.0001) compared with those taken while receiving delayed release tablets. Adverse event profiles were similar between both formulations. CONCLUSIONS Delayed release tablets proved more effective in achieving therapeutic serum posaconazole concentrations than posaconazole suspension, with minimal difference in adverse events, in pediatric hematology/oncology patients.

Abstract
Limited data exist on intravenous (IV) posaconazole dosing and the risk for hepatotoxicity it confers to children. In this study, we evaluated dosing and resulting trough levels in 10 pediatric patients on IV posaconazole. A therapeutic level in these patients was achieved 95% of the time. We found a median minimum effective dose of 6.55 mg/kg of body weight. No correlation was found between the duration or posaconazole trough level and an increased alanine transaminase level.

Abstract
Invasive fungal infections (IFIs) are the most frequent cause of morbidity and mortality in immunocompromised children. Voriconazole is the first-line antifungal choice in the treatment of IFIs like aspergillosis. Voriconazole pharmacokinetics vary widely among patients and voriconazole is metabolized mainly in the liver by the CYP2C19 enzyme, which is highly polymorphic. The CYP2C19*17 allele is characterized by the presence of four single nucleotide polymorphisms expressing an ultra-rapid enzyme phenotype with an accelerated voriconazole metabolism, is associated with low (sub-therapeutic) plasma levels in patients treated with the standard dose. Considering that in our center a high percentage of children have sub-therapeutic levels of voriconazole when treated with standard doses, we sought to determine the frequency of the CYP2C19*17 polymorphism (rs12248560) in a Chilean population and determine the association between voriconazole concentrations and the rs12248560 variant in immunocompromised children. First, we evaluated the frequency of the rs12248560 variant in a group of 232 healthy Chilean children, and we found that 180 children (77.6%) were non-carriers of the rs12248560 variant, 49 children (21.1%) were heterozygous carriers for rs12248560 variant and only 3 children (1.3%) were homozygous carriers for rs12248560 variant, obtaining an allelic frequency of 12% for variant in a Chilean population. To determine the association between voriconazole concentrations and the rs12248560 variant, we analyzed voriconazole plasma concentrations in a second group of 33 children treated with voriconazole. In these patients, carriers of the rs12248560 variant presented significantly lower voriconazole plasma concentrations than non-carriers (p = 0,011). In this study, we show the presence of the rs12248560 variant in a Chilean population and its accelerating effect on the pharmacokinetics of voriconazole in pediatric patients. From these data, it would be advisable to consider the variant of the patient prior to calculating the dosage of voriconazole.

Abstract
Pediatric patients with malignancies and transplant recipients are at high risk of infection-related morbidity and mortality. Children at the highest risk for infections are those with acute myeloid leukemia (AML), relapsed acute lymphoblastic leukemia (ALL), and hematopoietic stem cell transplant recipients (HSCT). These patients are at high risk for life-threatening bacterial, viral, and fungal infections which are associated with prolonged hospital stay, poor quality of life, and increased healthcare cost and death. Recognition of risk factors which predisposes them to infections, early identification of signs and symptoms of infections, prompt diagnosis, and empiric/definitive treatment are the mainstay in reducing infection-related morbidity and mortality. Infection control and prevention programs also play a crucial role in preventing hospital-acquired infections in these immunosuppressed hosts.

Abstract
The main indications for antifungal drug administration in pediatrics are reviewed as well as an update of the data of antifungal agents and antifungal policies performed. Specifically, antifungal therapy in three main areas is updated as follows: a) Prophylaxis of premature neonates against invasive candidiasis; b) management of candidemia and meningoencephalitis in neonates; and c) prophylaxis, empiric therapy, and targeted antifungal therapy in children with primary or secondary immunodeficiencies. Fluconazole remains the most frequent antifungal prophylactic agent given to high-risk neonates and children. However, the emergence of fluconazole resistance, particularly in non-albicans Candida species, should be considered during preventive or empiric therapy. In very-low birth-weight neonates, although fluconazole is used as antifungal prophylaxis in neonatal intensive care units (NICU's) with relatively high incidence of invasive candidiasis (IC), its role is under continuous debate. Amphotericin B, primarily in its liposomal formulation, remains the mainstay of therapy for treating neonatal and pediatric yeast and mold infections. Voriconazole is indicated for mold infections except for mucormycosis in children >2 years. Newer triazoles-such as posaconazole and isavuconazole-as well as echinocandins, are either licensed or under study for first-line or salvage therapy, whereas combination therapy is kept for refractory cases.

Abstract
BACKGROUND Treatment of relapsed childhood acute lymphoblastic leukemia (ALL) is particularly challenging due to the high treatment intensity needed to induce and sustain a second remission. To improve results, it is important to understand how treatment-related toxicity impacts survival. PROCEDURE In this retrospective population-based study, we described the causes of death and estimated the risk for treatment-related mortality in patients with first relapse of childhood ALL in the Nordic Society of Paediatric Haematology and Oncology ALL-92 and ALL-2000 trials. RESULTS Among the 483 patients who received relapse treatment with curative intent, we identified 52 patients (10.8%) who died of treatment-related causes. Twelve of these died before achieving second remission and 40 died in second remission. Infections were the cause of death in 38 patients (73.1%), predominantly bacterial infections during the chemotherapy phases of the relapse treatment. Viral infections were more common following hematopoietic stem cell transplantation (HSCT) in second remission. Independent risk factors for treatment-related mortality were as follows: high-risk stratification at relapse (hazard ratio [HR] 2.2; 95% confidence interval [CI] 1.3-3.9; P < 0.01), unfavorable cytogenetic aberrations (HR 3.4; 95% CI 1.3-9.2; P = 0.01), and HSCT (HR 4.64; 95% CI 2.17-9.92; P < 0.001). In contrast to previous findings, we did not observe any statistically significant sex or age differences. Interestingly, none of the 17 patients with Down syndrome died of treatment-related causes. CONCLUSIONS Fatal treatment complications contribute significantly to the poor overall survival after relapse. Implementation of novel therapies with reduced toxicity and aggressive supportive care management are important to improve survival in relapsed childhood ALL.

Abstract
Invasive fungal infections are one of the major complications in pediatric patients during prolonged neutropenia after chemotherapy. Evaluation of the efficacy and safety of the triazole posaconazole in these patients is missing. This multicenter survey analyzed trough concentrations of 33 pediatric patients with a median age of 8 years during 108 neutropenic episodes who received prophylactic posaconazole oral suspension. A total of 172 posaconazole trough levels were determined to median 438 ng/ml (range 111-2011 ng/ml; mean 468 ± 244 ng/ml). Age and gender had no influence on posaconazole plasma levels. Posaconazole was not discontinued due to adverse events in any of the patients. Only hepatic parameters significantly increased beyond the upper normal limit to median values of ALT of 87 U/l (P < .0001), and AST of 67 U/l (P < .0001). One patient with a median posaconazole trough concentration of 306 ng/ml experienced an invasive fungal infection. In conclusion, posaconazole was effective, safe and feasible in 33 pediatric patients with neutropenia ≥5 days after chemotherapy. Median posaconazole plasma concentrations were approximately 1.6-fold lower than the recommended plasma level of 700 ng/ml. Larger patient cohorts are needed to evaluate these findings.

Abstract
Talaromyces (Penicillium) marneffei infection is a fatal disseminated mycosis caused by the dimorphic fungus Talaromyces marneffei; the therapeutic strategies for this infectious disease are limited. The aim of this retrospective study was to evaluate the efficacy and safety of voriconazole for treating patients with disseminated T. marneffei infection with or without HIV infection in a clinical setting. Patients who intravenously received voriconazole (6 mg/kg q12 h for the first 24 h followed by 4 mg/kg q12 h) as the initial antifungal treatment were enrolled. The duration of the following antifungal treatment varied at the discretion of the investigators according to the patient responses. The primary global response was evaluated at Week 16 or at the end of treatment (EOT). Follow-up evaluations were performed at 6 months and 1 year after the EOT. Seventeen patients were enrolled in this study, but three were not evaluable because the treatment was prematurely discontinued. Among the remaining fourteen patients, ten patients had complete response and three had partial response at Week 16. Only one patient was determined to have failed response. Follow-up assessments in eleven patients showed that eight patients were cured and the remaining three patients relapsed at 6 months after the EOT. These eight patients were assessed 1 year later, and none of them had relapsed. No adverse events associated with voriconazole were recorded during the treatment. The results from our study suggest that voriconazole is an effective, well-tolerated therapeutic option for disseminated T. marneffei infection.

Abstract
INTRODUCTION Invasive fungal diseases (IFDs) are a leading cause of morbidity and mortality among immunocompromised patients with bone marrow failure syndromes, hematological malignancies, hematopoietic stem cell transplantation (HSCT), those admitted in intensive care units (ICUs) and those with prolonged febrile neutropenia. IFDs occur in a setting of multiple morbidities and are associated with case fatality rates between 30 and 70%. Along with the development of classes and compounds, the last two decades have seen substantial improvements in the prevention and management of these infections and an overall increased use of antifungal agents. Areas covered: All antifungal agents, including amphotericin B formulations, echinocandins and the triazoles, may cause hepatic toxicity that ranges from mild and asymptomatic abnormalities in liver function tests to substantial liver injury and fulminant hepatic failure. Expert opinion: The present article reviews incidence and severity of hepatotoxicity associated with different classes and agents to provide a better understanding of this specific end organ toxicity and safer use of antifungal agents A thorough understanding of the distribution, metabolism, elimination and drug-drug interactions of antifungal agents used for management of IFDs in combination with safety data from clinical trials, pharmacokinetic and pharmacodynamic studies may guide the use of antifungal treatment in patients at high risk for the development of hepatic dysfunction and in those with underlying liver damage due to cytotoxic therapy.

Abstract
Background Antifungal prophylaxis is currently regarded as the gold standard in situations with allo-genetic hematopoietic stem cell transplantation (allo-HSCT). However, the epidemiological information regarding prophylaxis of invasive fungal diseases (IFDs) is not clear in China. Methods We report the first large-scale (1053 patients) observational study of the prophylaxis and management of IFDs among patients with allo-HSCT in China. Results The incidence rates of IFD after primary antifungal prophylaxis (PAP), secondary antifungal prophylaxis (SAP), and non-prophylaxis were 22.7 vs. 38.6 vs. 68.6 %, respectively (P = 0.0000). The median time from transplantation to IFD was 45 days in PAP patients, 18 days in SAP patients, and 12 days in non-prophylaxis patients. Aspergillus spp. represents the most common type of fungal infection. Independent risk factors for IFD in allo-HSCT patients with PAP were age, having human leukocyte antigen (HLA)-haploidentical or matched unrelated donor, decreased albumin levels, and the use of itraconazole as the prophylactic antifungal agent. Among SAP transplant recipients, there was no significant risk factor for IFDs. The incidence rates of overall survival (OS) in the PAP, SAP, and no prophylaxis groups were 85.07, 78.80, and 74.82, respectively (P = 0.01). Conclusions This observational study indicates that prophylaxis of IFD is helpful to reduce the incidence of IFDs and improve the OS of patients after allo-HSCT.

Abstract
Invasive aspergillosis (IA) is a disease of increasing importance in pediatrics due to growth of the immunocompromised populations at risk and improvements in long-term survival for many of these groups. While general principles of diagnosis and therapy apply similarly across the age spectrum, there are unique considerations for clinicians who care for children and adolescents with IA. This review will highlight important differences in the epidemiology, clinical manifestations, diagnosis, and therapy of pediatric IA.

Abstract
The purpose of this study was to explore gastrointestinal dissolution, supersaturation and precipitation of the weakly basic drug posaconazole in humans, and to assess the impact of formulation pH and type on these processes. In a cross-over study, two posaconazole suspensions (40 mg dispersed in 240 mL water at pH 1.6 and pH 7.1, respectively) were intragastrically administered; subsequently, gastric and duodenal fluids were aspirated. In parallel, blood samples were collected. Additionally, posaconazole was intragastrically administered as a solution (20 mg in 240 mL water, pH 1.6). When posaconazole was administered as an acidified suspension, supersaturated duodenal concentrations of posaconazole were observed for approximately 45 min. However, extensive intestinal precipitation was observed. Administration of the neutral suspension resulted in subsaturated concentrations with a mean duodenal AUC0-120 min and Cmax being approximately twofold lower than for the acidified suspension. The mean plasma AUC0-8 h of posaconazole was also twofold higher following administration of the acidified suspension. Similar to the acidified suspension, significant intestinal precipitation (up to 92%) was observed following intragastric administration of the posaconazole solution. This study demonstrated for the first time the gastrointestinal behavior of a weakly basic drug administered in different conditions, and its impact on systemic exposure.

Abstract
BACKGROUND Antifungal prophylaxis remains challenging in immunocompromised children as no clear consensus has yet been reached about which drug to be used. Posaconazole has a broad spectrum of activity, a favorable safety profile and excellent prophylactic activity in adults. However, a lack of pharmacokinetic studies in pediatric patients hampers routine implementation. This study investigates the pharmacokinetics of a newly introduced posaconazole dosing regimen based on the body surface area in pediatric hematologic patients. METHODS In this prospective pharmacokinetic study, 8 blood samples were taken during 1 dosing interval at steady state in children aged 13 years or younger with hematologic malignancy, who were treated prophylactically with posaconazole oral suspension at a dose of 120 mg/m 3 times daily. Posaconazole plasma concentrations were determined using high-performance liquid chromatography fluorescence detection. RESULTS One hundred twelve samples were taken from 14 patients with a mean age of 6.7 ± 2.8 years. A median posaconazole daily dose of 100.0 mg (77.3-100.0) 3 times daily (tid), corresponding to a median of 117.9 mg/m (112.2-120.4) tid, resulted in mean trough posaconazole plasma concentrations of 0.85 ± 0.56 mg/L. Pharmacokinetic analysis revealed a clearance of 0.8 L/(h kg) (0.5-1.4). No invasive fungal infections or adverse events were encountered during treatment. CONCLUSIONS Posaconazole is a promising antifungal agent to be used prophylactically in hematologic patients aged 13 years or younger. Administering posaconazole oral suspension in a dosage of 120 mg/m tid results in adequate posaconazole plasma exposure, without significant adverse events.

Abstract
Posaconazole has been proven to be effective for antifungal prophylaxis in adults after hematopoietic stem cell transplantation (HSCT). Due to low gastrointestinal resorption of posaconazole suspension, bioavailability is impaired. Fatty food improves the uptake of posaconazole, but insufficient data on the pharmacokinetics of posaconazole in pediatric patients are available so far. The single-center analysis investigated 161 posaconazole serum concentrations in 27 pediatric patients after HSCT receiving 12 mg·kg BW(-1)·d(-1) posaconazole suspension depending on age, gender, and intestinal graft-versus-host (iGvHD) disease, and the influence of posaconazole on cyclosporine A plasma concentrations. To improve the uptake of posaconazole, one patient cohort received higher fat nutrition with the drug administration. A comparison of the regular nutrition and higher-fat nutrition groups revealed the following values: 31 (27.4%) versus 8 (16.7%) < 500 ng/ml; 12 (10.6%) versus 7 (14.6%) 500-700 ng/ml; 8 (7.1%) versus 6 (12.5%) 700-1000 ng/ml; 51 (45.1%) versus 21 (43.8%) 1000-2000 ng/ml; and 11 (9.7%) versus 6 (12.5%) > 2000 ng/ml. The mean posaconazole concentrations in patients with regular nutrition was 1123 ± 811 ng/ml and with higher-fat nutrition was 1191 ± 673 ng/ml. Posaconazole levels in patients with iGvHD were significantly lower (P = 0.0003) than in patients without GvHD. The majority of samples showed a sufficient posaconazole concentration above 700 ng/ml. Posaconazole levels were slightly higher in patients with higher-fat nutrition and significantly lower in patients with iGvHD. Cyclosporine A levels were not significantly higher during posaconazole administration.

Abstract
Posaconazole is a triazole antifungal agent that has broad-spectrum activity against many yeasts and filamentous fungi, including Candida species, Cryptococcus neoformans, Aspergillus species, and Zygomycetes. This drug has been approved for the prevention of invasive fungal infections in patients with neutropenia and for the treatment of invasive fungal infections in hematopoietic stem cell transplant recipients with graft-versus-host disease. Studies on the clinical efficacy, safety, tolerability, and cost-effectiveness of posaconazole therapy were performed using the oral suspension form of the drug. Pharmacokinetic studies have found that the oral suspension form of posaconazole has problemeatic bioavailability: its absorption is affected by concomitant medication and food. This article discusses the pharmacokinetic properties of the newly developed posaconazole delayed-release tablet formulation and reviews the efficacy, safety, and cost-effectiveness of both the oral suspension and the new tablet formulation. In conclusion, the posaconazole tablet formulation has better systemic bioavailability, thereby enabling once-daily administration and better absorption in the presence of concomitant medication and food. However, well-designed clinical studies are needed to evaluate the use of the tablet formulation in real-life settings.
