Abstract
Fluconazole (2-(2,4-difluorophenyl)-1,3-bis(1H-1,2,4-triazol-1-yl)propan-2-ol), which was patented in 1981 and introduced for commercial use in 1988, is a widely utilized antifungal drug whose mechanism of action involves inhibition of the activity of 14-α lanosterol demethylase. Its safety and effectiveness have established it as one of the most frequently employed antifungal agents. Resistance to azole antifungal drugs is becoming more common. It may be related to a mutation of the gene encoding the enzyme. To address this issue, molecules with modifications in three main regions of fluconazole, namely the hydroxyl group, the aromatic ring, and the 1,2,4-triazole rings, have been synthesized in an attempt to create more potent antifungal drugs. These modifications aim at enhancing the effectiveness against microorganisms and improving pharmacokinetic parameters and safety profiles of the synthesized compounds. The present review explores the synthesis of fluconazole derivatives, accompanied by insights into the results of biological studies evaluating the therapeutic effects of these compounds.

Abstract
Tinea capitis is a common fungal infection caused by dermatophytes in children, but it is rare in infants. Although oral itraconazole has been widely used to treat tinea capitis, its use in infants is limited due to its low prevalence in this age group. A previous study reported the effectiveness of itraconazole continuous therapy in treating infantile tinea capitis caused by Microsporum canis. However, this approach has not been extended to tinea capitis caused by other fungi. In this study, we present four cases of infantile tinea capitis treated with continuous itraconazole oral solution therapy (5 mg/kg/day). Two patients were infected with M. canis, one patient with Nannizzia gypsea, and another with Trichophyton tonsurans. This study assesses the efficacy and safety of itraconazole oral solution continuous therapy, expanding our understanding by demonstrating its effectiveness for infantile tinea capitis caused by T. tonsurans and N. gypsea.

World J Pediatr 2023; 19:1139-1148. [PMID: 36973599 DOI: 10.1007/s12519-023-00711-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 02/24/2023] [Indexed: 03/29/2023]
Abstract
BACKGROUND Antibiotics are widely prescribed among children and pregnant women, but their safety profile is controversial. This study aimed to summarize and appraise current evidence for the potential impact of antibiotic exposure on pregnancy outcomes and children's health. METHODS PubMed, Embase, Web of Science and the Cochrane Database of Systematic Reviews were searched from inception to June 2022. Meta-analyses of any study design comparing the impact of antibiotic exposure with nonexposure among children, pregnant women and prepregnant women on adverse health outcomes of children and pregnancy were retrieved. The quality of evidence was assessed by a Measurement Tool to Assess Systematic Reviews 2 (AMSTAR2) and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE). Data were reanalyzed, and the credibility of the evidence was determined. RESULTS Out of 2956 studies identified, 19 articles with 39 associations were included. Totally 19 of the associations (48.72%) were statistically significant with a P value ≤ 0.05, while only six were supported by highly suggestive evidence. Children with postnatal antibiotic exposure had a higher risk of developing asthma odds ratio (OR): 1.95, 95% confidence interval (CI): 1.76-2.17, wheezing (OR: 1.81, 95% CI 1.65-1.97) and allergic rhinoconjunctivitis (OR: 1.66, 95% CI 1.51-1.83), with prediction intervals excluding the nulls. Quality assessed by both AMSTAR2 and GRADE of included meta-analyses were very low in general. CONCLUSIONS Antibiotic exposure in early life was associated with children's long-term health, especially in cases of allergic diseases. Prenatal exposure might also influence children's health in some aspects but requires more high-quality evidence. Potential adverse effects of antibiotics on pregnancy outcomes were not observed in our study. Studies with higher quality and better quantification of antibiotic exposure are needed in the future.

Plasma and Cerebrospinal Fluid Concentrations of Micafungin Administered at High Doses in Critically Ill Infants with Systemic Candidiasis: A Pooled Analysis of Two Studies. Pharmaceuticals (Basel) 2023; 16:ph16030472. [PMID: 36986569 PMCID: PMC10051811 DOI: 10.3390/ph16030472] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 03/09/2023] [Accepted: 03/13/2023] [Indexed: 03/30/2023] Open
Abstract
Background: Neonates may require higher doses of micafungin than adults to reach the therapeutic effect for increased plasma clearance. Only poor and inconclusive data are available still now to support this hypothesis, especially with regard to central nervous system micafungin concentrations. To assess the pharmacokinetics of increased doses (8 to 15 mg/kg/day) of micafungin in preterm and term neonates with invasive candidiasis and to complete previously presented results, we analyzed the pharmacokinetic data on a total of 53 newborns treated with micafungin, whereby 3 of them had Candida meningitis and hydrocephalus. Methods: Fifty-three neonates with systemic candidiasis, three of them with meningitis, were treated for at least 14 days with intravenous micafungin (Mycamine®) at a dosage ranging from 8 to 15 mg/kg/day. Plasma and cerebrospinal fluid (CSF) concentrations of micafungin were measured before the drug administration and at 1, 2, and 8 h after the end of the infusion using high-performance liquid chromatography (HPLC). Systemic exposure was assessed according to AUC0-24, plasma clearance (CL), and half-life measured in 52/53 patients, divided by chronological age. Results and conclusions: The mean micafungin clearance is higher in neonates than in older infants (0.036 L/h/kg before 28 days of life versus 0.028 L/h/kg after 120 days). The drug half-life is shorter in neonates than in older patients (13.5 h before 28 days of life versus 14.4 h after 120 days). With doses ranging between 8 and 15 mg/kg/day, micafungin crosses the blood-brain barrier reaching therapeutic levels in CSF.

A potential implication of UDP-glucuronosyltransferase 2B10 in the detoxification of drugs used in pediatric hematopoietic stem cell transplantation setting: an in silico investigation. BMC Mol Cell Biol 2022; 23:5. [PMID: 35062878 PMCID: PMC8781437 DOI: 10.1186/s12860-021-00402-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Accepted: 12/22/2021] [Indexed: 12/19/2022] Open
Abstract
Background Sinusoidal occlusion syndrome (SOS) is a potentially severe complication following hematopoietic stem cell transplantation (HSCT) in pediatric patients. Treatment related risk factors such as intensity of conditioning, hepatotoxic co-medication and patient related factors such as genetic variants predispose individuals to develop SOS. The variant allele for SNP rs17146905 in UDP-glucuronosyl transferase 2B10 (UGT2B10) gene was correlated with the occurrence of SOS in an exome-wide association study. UGT2B10 is a phase II drug metabolizing enzyme involved in the N-glucuronidation of tertiary amine containing drugs. Methods To shed light on the functionality of UGT2B10 enzyme in the metabolism of drugs used in pediatric HSCT setting, we performed in silico screening against custom based library of putative ligands. First, a list of potential substrates for in silico analysis was prepared using a systematic consensus-based strategy. The list comprised of drugs and their metabolites used in pediatric HSCT setting. The three-dimensional structure of UGT2B10 was not available from the Research Collaboratory Structural Bioinformatics - Protein Data Bank (RCSB - PDB) repository and thus we predicted the first human UGT2B10 3D model by using multiple template homology modeling with MODELLER Version 9.2 and molecular docking calculations with AutoDock Vina Version 1.2 were implemented to quantify the estimated binding affinity between selected putative substrates or ligands and UGT2B10. Finally, we performed molecular dynamics simulations using GROMACS Version 5.1.4 to confirm the potential UGT2B10 ligands prioritized after molecular docking (exhibiting negative free binding energy). Results Four potential ligands for UGT2B10 namely acetaminophen, lorazepam, mycophenolic acid and voriconazole n-oxide intermediate were identified. Other metabolites of voriconazole satisfied the criteria of being possible ligands of UGT2B10. Except for bilirubin and 4-Hydroxy Voriconazole, all the ligands (particularly voriconazole and hydroxy voriconazole) are oriented in substrate binding site close to the co-factor UDP (mean ± SD; 0.72 ± 0.33 nm). Further in vitro screening of the putative ligands prioritized by in silico pipeline is warranted to understand the nature of the ligands either as inhibitors or substrates of UGT2B10. Conclusions These results may indicate the clinical and pharmacological relevance UGT2B10 in pediatric HSCT setting. With this systematic computational methodology, we provide a rational-, time-, and cost-effective way to identify and prioritize the interesting putative substrates or inhibitors of UGT2B10 for further testing in in vitro experiments.

Abstract
PURPOSE Neonatal infections are associated with high morbidity and mortality rates. Optimal treatment of these infections requires knowledge of neonatal pharmacology and integration of neonatal developmental pharmacokinetics of antimicrobial drugs in the design of dosing regimens for use with different gestational and postnatal ages. Population pharmacokinetic (PK) and pharmacodynamic (PD) models are used to personalize the use of these drugs in these fragile patients. The final step to further minimize variability in an individual patient is therapeutic drug monitoring (TDM), where the same population PK/PD models are used in concert with optimally drawn blood samples to further fine-tune therapy. The purpose of this manuscript is to describe the present status and future role of model-based precision dosing and TDM of antimicrobial drugs in neonates. METHODS PubMed was searched for clinical trials or clinical studies of TDM in neonates. RESULTS A total of 447 papers were retrieved, of which 19 were concerned with antimicrobial drugs. Two papers (one aminoglycoside and one vancomycin) addressed the effects of TDM in neonates. We found that, in addition to aminoglycosides and vancomycin, TDM also plays a role in beta-lactam antibiotics and antifungal drugs. CONCLUSION There is a growing awareness that, in addition to aminoglycosides and vancomycin, the use of beta-lactam antibiotics, such as amoxicillin and meropenem, and other classes of antimicrobial drugs, such as antifungal drugs, may benefit from TDM. However, the added value must be shown. New analytical techniques and software development may greatly support these novel developments.

Abstract
To increase the understanding of how drugs behave following oral administration to the pediatric population, the aim of the present study was to investigate the solubilization of fluconazole and ibuprofen during simulated gastro-intestinal (GI) digestion, using an immediate transfer model mimicking pediatric GI digestion. The effects of infant formula and digestion, on the drug solubilization, were studied using simulated fasted and fed state digestion media in the presence and absence of digestive enzymes. Additionally, the effect of digestion media viscosity on the solubilization process was investigated. It was found that the solubilization of fluconazole was unaffected by all tested parameters, as the entire estimated dose equivalent was solubilized in the aqueous phase throughout all digestion studies. In contrast, the solubilization of ibuprofen was affected by all the tested parameters, i.e. in the fasted state, the solubilization of ibuprofen was limited by its solubility in the aqueous phase of the simulated GI digestion media, whereas the solubilization in the fed state was affected by drug partitioning between the lipid and the aqueous phases, and therefore by the digestion of the lipid phase. Adding Nestlé Thicken Up™, containing xanthan gum as a thickening agent, to the digestion medium increased its viscosity, which in turn resulted in a reduced initial digestion rate, increased pH fluctuations, as well as high variability in all drug solubilization data as evident in large standard deviations. Furthermore, the increased digestion medium viscosity decreased the drug recovery from the combined pellet and aqueous phase. The observed viscosity effects might translate into a more variable and lower oral bioavailability.

Abstract
Invasive candidiasis accounts for approximately 10% of nosocomial infections in preterm infants, with an incidence of 1% to 4% among neonatal intensive care unit (NICU) admissions and a mortality as high as 20% to 30%. These outcomes warrant improved treatment and prevention strategies for infants at highest risk. The Infectious Diseases Society of America provides guidelines on antifungal medications for the prophylaxis and treatment of candidiasis in NICUs; however, there are still variations in practice on the use of fluconazole for prophylaxis and treatment of invasive candidiasis. This review provides specific information regarding fluconazole activity, pharmacokinetics, and a literature evaluation of dosing strategies and comparisons to other treatments in the neonatal population.

Abstract
PURPOSE To assess and compare the efficacy and safety of posaconazole with fluconazole for the prevention of invasive fungal infections in children who were undergoing induction therapy for acute lymphoblastic leukemia (ALL). To develop an approach to predict invasive fungal infections in ALL patients who accepted posaconazole prophylaxis. METHODS This was a single-center, retrospective cohort study of patients with newly diagnosed ALL, comparing invasive fungal infections in patients who received no prophylaxis, posaconazole prophylaxis, or fluconazole prophylaxis during induction therapy. A propensity score-weighted logistic regression model was used to adjust for confounders. Hepatotoxicity was assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) criteria. RESULTS Out of the 155 ALL patients, 60 received no prophylaxis, 70 received posaconazole prophylaxis, and 25 received fluconazole prophylaxis. Posaconazole prophylaxis reduced the odds of invasive fungal infections by > 60%, prolonged infection-free survival significantly, and did not increase the risk of hepatotoxicity. Additionally, we found that the combination of age at diagnosis, clinically documented bacterial infection in the first 15 days of induction therapy, and absolute neutrophil count (ANC) curve enabled significant prediction of the susceptibility to infections after receiving posaconazole prophylaxis. CONCLUSIONS Our findings supported using targeted prophylaxis with posaconazole in ALL children undergoing induction chemotherapy. Age, clinically documented bacterial infection and ANC are important predictors of invasive fungal infections in patients with posaconazole prophylaxis.

Abstract
We evaluated the in vitro antifungal activity of essential oils obtained from the aromatic plants Laurus nobilis, Thymus vulgaris, Mentha piperita, Cymbopogon citratus and Lippia junelliana against the following Candida species isolated from clinical samples: C. krusei (n = 10); C. albicans (n = 50); C. glabrata (n = 70) and C. parapsilosis (n = 80). The minimal inhibitory concentration (MIC) was determined according to EDef 7.3.1 document from EUCAST. Amphotericin B and fluconazole were the antifungal drugs used as inhibition control. The concentration ranges evaluated were 0.4-800 and 0.03-128 mg l-1 for essential oils and antifungal drugs, respectively. MIC50 and MIC90, mode and ranges were calculated. All the Candida spp. evaluated were susceptible to amphotericin B (MIC ≤ 1 mg l-1), while fluconazole was inactive for C. krusei (MIC ≥ 32 mg l-1) and intermediate for C. glabrata (MIC≤ 32 mg l-1). The essential oils showed antifungal activity on Candida spp. tested with MIC90 values ranging from 0.8 to 800 mg l-1. In general, the most active essential oils were L. nobilis and T. vulgaris (MIC90 0.8-0.16 mg l-1), and the least active was C. officinalis (MIC90 400-800 mg l-1). C. krusei was inhibited by 5/6 of the essential oils evaluated, and C. glabrata was the least susceptible one. This in vitro study confirms the antifungal activity of these six essential oils assayed which could be a potential source of new molecules useful to control fungal infections caused by some Candida species, including those resistant to antifungal drugs.

Abstract
AIMS The pharmacokinetics (PK) of fluconazole and micafungin differ in neonates compared with children and adults. Dosing instructions in product labels appear to be inconsistent with the emerging scientific evidence. Limited information is available on the safety profile of these agents in neonates. Our objective was to study the population PK and safety of both drugs, randomly administered in neonates with suspected or confirmed systemic candidiasis. METHODS Neonates were randomized 1:1 to fluconazole (loading dose 25 mg kg-1 ; maintenance dose 12 mg kg-1 day-1 or 20 mg kg-1 day-1 , respectively, for infants <30 weeks or ≥30 weeks' corrected gestational age) or micafungin (loading dose 15 mg kg-1 day-1 ; maintenance dose 10 mg kg-1 day-1 ). PK samples were taken on treatment days 1 and 5. Population parameters were determined using NONMEM and Monte Carlo simulations performed to reach predefined targets. Clinical and laboratory data, and adverse events were collected up to 36 weeks' corrected gestational age or hospital discharge. RESULTS Thirty-six neonates were enrolled. The median (range) gestational age was 28.2 (24.1-40.1) and 26.8 (23.5-40.0) weeks for fluconazole and micafungin, respectively. Based on 163 PK samples, the median population clearance (l h-1 kg-1 ) and volume of distribution (l kg-1 ) for fluconazole were: 0.015 [95% confidence interval (CI) 0.008, 0.039] and 0.913, and for micafungin were: 0.020 (95% CI 0.010, 0.023) and 0.354 (95% CI 0.225, 0.482), respectively. The loading dose was well tolerated. No adverse events associated with micafungin or fluconazole were reported. CONCLUSION Based on Monte Carlo simulations, a loading dose for fluconazole and dosing higher than recommended for both drugs are required to increase the area under the plasma drug concentration-time curve target attainment rate in neonates.

Abstract
Preterm infants, born with immature innate immunity, are less likely to develop anaphylaxis. Fluconazole prophylaxis during the first six weeks of life decreases invasive candidiasis in very low birth weight infants. Adverse effects of fluconazole are very rare. In this study, we report a newborn (a male, 26 weeks gestation and 900 g birth weight) who developed anaphylaxis after fluconazole administration. Hypotension and erythematous rash were present. We believe this to be the first anaphylaxis case in newborns caused by fluconazole in literature. Clinicians should be aware of the possibility of this potentially fatal adverse effect occurring with intravenous fluconazole.

Abstract
OBJECTIVES To evaluate the safety and efficacy of different doses of fluconazole used for invasive prophylaxis of fungal infection in neonates. STUDY DESIGN A systematic search was conducted with PubMed, Scopus, and Web of Science. A manual search was performed as well. Only randomized controlled trials of neonates in a neonatal intensive care unit (NICU) who received fluconazole prophylaxis for invasive fungal infection, regardless of the dose or therapeutic regimen, were included in this review. Data on baseline characteristics, outcomes incidence of proven invasive Candida infection, overall mortality, and invasive Candida infection-related mortality were extracted. RESULTS Eleven studies were included in the review, with fluconazole doses of 3, 4, or 6?mg/kg. When the incidence of invasive Candida and invasive Candida-related mortality were considered as outcomes, the 3 and 6?mg/kg fluconazole doses were found to be statistically superior to placebo (OR, 5.48 [95% credible interval, 1.81-18.94] and 2.63 [1.18-7.02], respectively, and 15.32 [1.54-54.31] and 9.14 [1.26-142.7], respectively), but data for the 3 doses were not statistically significantly different. CONCLUSIONS Use of the lowest fluconazole dose (3?mg/kg) should be recommended for Candida prophylaxis in neonates, given that increasing the fluconazole dose is not associated with higher efficacy and has greater potential for toxicity and increased cost.

Abstract
Background Long courses of oral corticosteroids are commonly used in children in the management of chronic conditions. Various adverse drug reactions (ADRs) are known to occur with their use. This systematic review aimed to identify the most common and serious ADRs and to determine their relative risk levels. Methods A literature search of Embase, Medline, International Pharmaceutical Abstracts, CINAHL, Cochrane Library and PubMed was performed with no language restrictions in order to identify studies where oral corticosteroids were administered to patients aged 28 days to 18 years of age for at least 15 days of treatment. Each database was searched from their earliest dates to January 2016. All studies providing clear information on ADRs were included. Results One hundred and one studies including 33 prospective cohort studies; 21 randomised controlled trials; 21 case series and 26 case reports met the inclusion criteria. These involved 6817 children and reported 4321 ADRs. The three ADRs experienced by the highest number of patients were weight gain, growth retardation and Cushingoid features with respective incidence rates of 21.1%, 18.1% and 19.4% of patients assessed for these ADRs. 21.5% of patients measured showed decreased bone density and 0.8% of patients showed osteoporosis. Biochemical HPA axis suppression was detected in 269 of 487 patients where it was measured. Infection was the most serious ADR, with twenty one deaths. Varicella zoster was the most frequent infection (9 deaths). Conclusions Weight gain, growth retardation and Cushingoid features were the most frequent ADRs seen when long-course oral corticosteroids were given to children. Increased susceptibility to infection was the most serious ADR.

Abstract
BACKGROUND Short-course oral corticosteroids are commonly used in children but are known to be associated with adverse drug reactions (ADRs). This review aimed to identify the most common and serious ADRs and to determine their relative risk levels. METHODS A literature search of EMBASE, MEDLINE, International Pharmaceutical Abstracts, CINAHL, Cochrane Library and PubMed was performed with no language restrictions to identify studies in which oral corticosteroids were administered to patients aged 28 days to 18 years of age for up to and including 14 days of treatment. Each database was searched from their earliest dates to December 2013. All studies providing clear information on ADRs were included. RESULTS Thirty-eight studies including 22 randomised controlled trials (RCTs) met the inclusion criteria. The studies involved a total of 3200 children in whom 850 ADRs were reported. The three most frequent ADRs were vomiting, behavioural changes and sleep disturbance, with respective incidence rates of 5.4%, 4.7% and 4.3% of patients assessed for these ADRs. Infection was one of the most serious ADRs; one child died after contracting varicella zoster. When measured, 144 of 369 patients showed increased blood pressure; 21 of 75 patients showed weight gain; and biochemical hypothalamic-pituitary-adrenal axis suppression was detected in 43 of 53 patients. CONCLUSIONS Vomiting, behavioural changes and sleep disturbance were the most frequent ADRs seen when short-course oral corticosteroids were given to children. Increased susceptibility to infection was the most serious ADR. TRIAL REGISTRATION NUMBER CRD42014008774. By PROSPERO International prospective register of systematic reviews.

Abstract
QUESTION I have a patient with persistent breast and nipple thrush. Other therapies have failed, so I have decided to treat her with a loading dose of 400 mg of oral fluconazole followed by 100 mg twice daily for at least 2 weeks. Is there any need for her to interrupt breastfeeding during this treatment? ANSWER Available data regarding fluconazole use during breastfeeding are reassuring. Fluconazole is also used in the treatment of fungal diseases in infants and has a good safety profile. Therefore, there is no need to interrupt breastfeeding when a mother is treated with fluconazole.

Abstract
Opportunistic mycoses increase the morbidity and mortality of immuno-compromised patients. Five Candida species have been shown to be responsible for 97% of worldwide cases of invasive candidiasis. Resistance of C. glabrata and C. krusei to azoles has been reported, and new, improved antifungal agents are needed. The current study was designed to evaluatethe activity of various polyphenolic compounds against Candida species. Antifungal activity was evaluated following the M27-A3 protocol of the Clinical and Laboratory Standards Institute, and antioxidant activity was determined using the DPPH assay. Myricetin and baicalein inhibited the growth of all species tested. This effect was strongest against C. glabrata, for which the minimum inhibitory concentration (MIC) value was lower than that of fluconazole. The MIC values against C. glabrata for myricitrin, luteolin, quercetin, 3-hydroxyflavone, and fisetin were similar to that of fluconazole. The antioxidant activity of all compounds was confirmed, and polyphenolic compounds with antioxidant activity had the greatest activity against C. glabrata. The structure and position of their hydroxyl groups appear to influence their activity against C. glabrata.

Abstract
AIM The aim of this study was to evaluate the attitude of Jordanian dentists towards the treatment of oral candidiasis and their current antifungal prescribing habits, shedding more light on the possible influence of their socio-professional factors on the pattern of prescribing and practice. METHODS A structured validated questionnaire was developed and tested; it was then emailed to a random sample of 600 Jordanian dental practitioners during the period of this cross-sectional survey. The questionnaire recorded practitioners' personal details and their attitude and prescribing of antifungal therapy for oral candidiasis. Statistical significance was based on probability values of <0.05 and was measured using the chi-square and Fisher's exact tests. Multiple logistic regression analysis was used to analyse the influence of respondents' socio-professional factors on their attitude towards oral candidiasis. RESULTS Of the 423 questionnaires returned, only 330 were included. The attitude of respondents was significantly influenced by their experience [odds ratio (OR) = 0.14; P < 0.001] and workplace (OR = 4.70; P < 0.001). Nystatin was the most commonly prescribed antifungal agent (78.2%), followed by miconazole (62.4%), which was prescribed for topical use. Systemic antifungals were prescribed by 21.2% of respondents, with a significant (P < 0.05) association with the country in which their qualification was obtained. CONCLUSION The attitude towards the treatment of oral candidiasis is much better among the least-experienced dentists working in private practice. Nystatin and miconazole are the most popular choices of antifungal agents among Jordanian dentists.

Abstract
BACKGROUND Antibiotic dosing in neonates varies between countries and centres, suggesting suboptimal exposures for some neonates. We aimed to describe variations and factors influencing the variability in the dosing of frequently used antibiotics in European NICUs to help define strategies for improvement. METHODS A sub-analysis of the European Study of Neonatal Exposure to Excipients point prevalence study was undertaken. Demographic data of neonates receiving any antibiotic on the study day within one of three two-week periods from January to June 2012, the dose, dosing interval and route of administration of each prescription were recorded. The British National Formulary for Children (BNFC) and Neofax were used as reference sources. Risk factors for deviations exceeding ±25% of the relevant BNFC dosage recommendation were identified by multivariate logistic regression analysis. RESULTS In 89 NICUs from 21 countries, 586 antibiotic prescriptions for 342 infants were reported. The twelve most frequently used antibiotics - gentamicin, penicillin G, ampicillin, vancomycin, amikacin, cefotaxime, ceftazidime, meropenem, amoxicillin, metronidazole, teicoplanin and flucloxacillin - covered 92% of systemic prescriptions. Glycopeptide class, GA <32 weeks, 5(th) minute Apgar score <5 and geographical region were associated with deviation from the BNFC dosage recommendation. While the doses of penicillins exceeded recommendations, antibiotics with safety concerns followed (gentamicin) or were dosed below (vancomycin) recommendations. CONCLUSIONS The current lack of compliance with existing dosing recommendations for neonates needs to be overcome through the conduct of well-designed clinical trials with a limited number of antibiotics to define pharmacokinetics/pharmacodynamics, efficacy and safety in this population and by efficient dissemination of the results.

Risk assessment for extending the Biopharmaceutics Classification System-based biowaiver of immediate release dosage forms of fluconazole in adults to the paediatric population.

Abstract
OBJECTIVES The paediatric population undergoes developmental changes in gastric pH, gastric emptying, intestinal transit time, membrane permeability, protein binding, body water, distribution and metabolism. It is widely recognised that changes in these parameters may result in an alteration of the plasma profile and thus in key bioequivalence parameters such as Cmax (maximum plasma concentration of drug) and area under the plasma concentration vs time profile curve. The aim of this work is to assess the risk of extending the biowaiver for immediate release dosage formulations of fluconazole from the adult to the paediatric population. METHODS AND KEY FINDINGS Fluconazole exhibits good solubility and very rapid dissolution characteristics in various pH media. The absorption of fluconazole in children is known to be complete (over 90%) and not impaired by elevated pH, which is prevalent during the early days of life. Dose numbers calculated using body surface area are less than 1. Therefore, the risk to drug absorption due to differences in gastric pH, gastric emptying, intestinal transit, membrane permeability and metabolising enzymes between adults and children is considered low. CONCLUSIONS Thus, it can be safely concluded that fluconazole meets highly soluble and highly permeable criteria in the paediatric population and can be allocated to class 1 of the Biopharmaceutics Classification System (BCS) for this population as well as in adults. Additionally, fluconazole has an excellent safety profile in children, similar to that in adults. The BCS-based biowaiver claimed in adults can be safely extended to the paediatric population provided that the requirements in excipient selection and dissolution profile comparison using BCS-based dissolution conditions as stated in the biowaiver monograph for fluconazole immediate release dosage forms in adults are fulfilled.

Abstract
Onychomycosis is a chronic infection of the nail unit, and its prevalence increases with age. Treatment options for children are similar to those for adults and include both oral and topical therapies. Oral agents, such as terbinafine, itraconazole, and fluconazole have been reported to have good efficacy and a low rate of side effects in children. Topical therapies, such as amorolfine and ciclopirox, can also be used as monotherapy or combined with oral agents to treat onychomycosis. Due to their thinner, faster-growing nails, children are more likely to respond to topical monotherapy than adults. There is currently insufficient data comparing emerging medical devices, such as laser therapy, with standard therapeutic options to recommend their use in children.

Abstract
Paediatric clinical pharmacology is the scientific study of medicines in children and is a relatively new subspecialty in paediatrics in the UK. Training encompasses both the study of the effectiveness of drugs in children (clinical trials) and aspects of drug toxicity (pharmacovigilance). Ethical issues in relation to clinical trials and also studies of the pharmacokinetics and drug metabolism in children are crucial. Paediatric patients require formulations that young children in particular are able to take. The scientific evidence generated from clinical trials, pharmacokinetic studies and studies of drug toxicity all need to be applied in order to ensure that medicines are used rationally in children.

Abstract
Drug metabolism importantly determines drug concentrations. The efficacy and safety of many drugs prescribed for children are, therefore, dependent on intraindividual and interindividual variation in drug-metabolising enzyme activity. During growth and development, changes in drug-metabolising enzyme activity result in age-related differences in drug disposition, most pronounced in preterm infants and young infants. The shape of the developmental trajectory is unique to the drug-metabolising enzyme involved in the metabolism of individual drugs. Other factors impacting drug metabolism are underlying disease, drug-drug interactions and genetic variation. The interplay of age with these other factors may result in unexpected variation in drug metabolism in children of different ages. Extrapolation of adult data to guide drug dosing in children should be done with caution. The younger the child, the less reliable is the extrapolation. This review aims to identify the primary sources of variability of drug metabolism in children, the knowledge of which can ultimately guide the practitioner towards effective and safe drug therapy.

Abstract
Toxic epidermal necrolysis (TEN) is a rare, life-threatening mucocutaneous condition, which may occur as an adverse reaction to a number of medications. The anitifungal agent, fluconazole, has been associated with TEN in limited reports, mainly in adults with HIV infection. We describe the case of a neonate with liver disease who developed TEN, presumably induced by fluconazole.
