Antifungal medication use during early pregnancy and the risk of congenital heart defects in the National Birth Defects Prevention Study, 1997-2011. Birth Defects Res 2024; 116:e2308. [PMID: 38343154 DOI: 10.1002/bdr2.2308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 01/02/2024] [Accepted: 01/15/2024] [Indexed: 02/15/2024]
Abstract
BACKGROUND Fungal infections are common among pregnant people. Recent studies suggest positive associations between oral antifungals used to treat fungal infections and congenital heart defects (CHDs). METHODS We estimated associations between first trimester antifungal use and 20 major, specific CHDs using data from the National Birth Defects Prevention Study (NBDPS), a multi-site, case-control study that included pregnancies with estimated delivery dates from October 1997 through December 2011. Infants with CHDs ("cases") were ascertained from 10 birth defect surveillance programs. Live born infants without major birth defects ("controls") were randomly selected from birth records or hospital discharge lists. First trimester antifungal use was self-reported via maternal interview. We estimated adjusted odds ratios (AORs) and 95% confidence intervals (CIs) using logistic regression with Firth's penalized likelihood. RESULTS First trimester antifungal use was reported by 148/11,653 (1.3%) case and 123/11,427 (1.1%) control participants. We estimated AORs for 12 CHDs; six had AORs >1.5 (tetralogy of Fallot, double outlet right ventricle with transposition of the great arteries [DORV-TGA], atrioventricular septal defect, hypoplastic left heart syndrome, pulmonary atresia, muscular ventricular septal defect), and one (pulmonary valve stenosis) had an AOR <0.7. All CIs included the null, except for DORV-TGA. CONCLUSIONS First trimester antifungal use was rare. We observed some positive associations for several specific CHDs in our analysis, although the CIs largely included the null. Results do not support a large increase in risk, but smaller increases in risk for certain CHD cannot be ruled out.

Abstract
PURPOSE Recent studies suggest increased birth defect risk associated with maternal use of specific oral antifungals. We estimated associations between first-trimester antifungal use and selected non-cardiac birth defects using National Birth Defects Prevention Study (NBDPS) data. METHODS Participants with a pregnancy affected by a study-eligible birth defect ("cases") were ascertained from 10 birth defect surveillance programs; participants who delivered livebirths without a major birth defect ("controls") were randomly selected from birth records or hospital discharge lists. First-trimester antifungal use was self-reported via maternal interview. We estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for birth defects with ≥5 exposed cases using logistic regression. We estimated crude ORs and exact 95% CIs for birth defects with 3-4 exposed cases. Additionally, we conducted a probabilistic bias analysis of exposure misclassification. RESULTS Our analysis included 19 624 cases and 11 427 controls; 257 (1.3%) cases and 123 (1.1%) controls reported first-trimester antifungal use. Of those who reported antifungals, 62.6% of cases and 64.2% of controls reported topical antifungals; 10.1% of cases and 4.9% of controls reported oral antifungals. We observed the strongest associations for encephalocele and Dandy-Walker malformation and modestly elevated estimates for several other defects. Bias-adjusted estimates were similar to the main analysis. CONCLUSION First-trimester antifungal use was positively associated with several birth defects in our analysis, although CIs were imprecise. Further study is warranted to investigate associations between antifungal use and birth defects, including potential bias due to confounding by indication.

A microRNA or messenger RNA point of departure estimates an apical endpoint point of departure in a rat developmental toxicity model. Birth Defects Res 2022; 114:559-576. [PMID: 35596682 PMCID: PMC9324934 DOI: 10.1002/bdr2.2046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 05/02/2022] [Accepted: 05/04/2022] [Indexed: 11/10/2022]
Abstract
Traditional developmental toxicity testing practice examines fetal apical endpoints to identify a point of departure (POD) for risk assessment. A potential new testing paradigm involves deriving a POD from a comprehensive analysis of molecular-level change. Here, the rat ketoconazole endocrine-mediated developmental toxicity model was used to test the hypothesis that maternal epigenomic (miRNA) and transcriptomic (mRNA) PODs are similar to fetal apical endpoint PODs. Sprague-Dawley rats were exposed from gestation day (GD) 6-21 to 0, 0.063, 0.2, 0.63, 2, 6.3, 20, or 40 mg/kg/day ketoconazole. Dam systemic, liver, and placenta PODs, along with GD 21 fetal resorption, body weight, and skeletal apical PODs were derived using BMDS software. GD 21 dam liver and placenta miRNA and mRNA PODs were obtained using three methods: a novel individual molecule POD accumulation method, a first mode method, and a gene set method. Dam apical POD values ranged from 2.0 to 38.6 mg/kg/day; the lowest value was for placenta histopathology. Fetal apical POD values were 10.9-20.3 mg/kg/day; the lowest value was for fetal resorption. Dam liver miRNA and mRNA POD values were 0.34-0.69 mg/kg/day, and placenta miRNA and mRNA POD values were 2.53-6.83 mg/kg/day. Epigenomic and transcriptomic POD values were similar across liver and placenta. Deriving a molecular POD from dam liver or placenta was protective of a fetal apical POD. These data support the conclusion that a molecular POD can be used to estimate, or be protective of, a developmental toxicity apical POD.

An adverse outcome pathway on the disruption of retinoic acid metabolism leading to developmental craniofacial defects. Toxicology 2021; 458:152843. [PMID: 34186166 DOI: 10.1016/j.tox.2021.152843] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 05/28/2021] [Accepted: 06/24/2021] [Indexed: 11/21/2022]
Abstract
Adverse outcome pathway (AOP) is a conceptual framework that links a molecular initiating event (MIE) via intermediate key events (KEs) with adverse effects (adverse outcomes, AO) relevant for risk assessment, through defined KE relationships (KERs). The aim of the present work is to describe a linear AOP, supported by experimental data, for skeletal craniofacial defects as the AO. This AO was selected in view of its relative high incidence in humans and the suspected relation to chemical exposure. We focused on inhibition of CYP26, a retinoic acid (RA) metabolizing enzyme, as MIE, based on robust previously published data. Conazoles were selected as representative stressors. Intermediate KEs are RA disbalance, aberrant HOX gene expression, disrupted specification, migration, and differentiation of neural crest cells, and branchial arch dysmorphology. We described the biological basis of the postulated events and conducted weight of evidence (WoE) assessments. The biological plausibility and the overall empirical evidence were assessed as high and moderate, respectively, the latter taking into consideration the moderate evidence for concordance of dose-response and temporal relationships. Finally, the essentiality assessment of the KEs, considered as high, supported the robustness of the presented AOP. This AOP, which appears of relevance to humans, thus contributes to mechanistic underpinning of selected test methods, thereby supporting their application in integrated new approach test methodologies and strategies and application in a regulatory context.

Abstract
OBJECTIVE To examine the risk of congenital malformations associated with exposure to oral fluconazole at commonly used doses in the first trimester of pregnancy for the treatment of vulvovaginal candidiasis. DESIGN Population based cohort study. SETTING A cohort of pregnancies publicly insured in the United States, with data from the nationwide Medicaid Analytic eXtract 2000-14. PARTICIPANTS Pregnancies of women enrolled in Medicaid from three or more months before the last menstrual period to one month after delivery, and infants enrolled for three or more months after birth. INTERVENTIONS Use of fluconazole and topical azoles was established by requiring one or more prescriptions during the first trimester of pregnancy. MAIN OUTCOME MEASURES Risk of musculoskeletal malformations, conotruncal malformations, and oral clefts (primary outcomes), associated with exposure to oral fluconazole, diagnosed during the first 90 days after delivery, were examined. RESULTS The study cohort of 1 969 954 pregnancies included 37 650 (1.9%) pregnancies exposed to oral fluconazole and 82 090 (4.2%) pregnancies exposed to topical azoles during the first trimester. The risk of musculoskeletal malformations was 52.1 (95% confidence interval 44.8 to 59.3) per 10 000 pregnancies exposed to fluconazole versus 37.3 (33.1 to 41.4) per 10 000 pregnancies exposed to topical azoles. The risks of conotruncal malformations were 9.6 (6.4 to 12.7) versus 8.3 (6.3 to 10.3) per 10 000 pregnancies exposed to fluconazole and topical azoles, respectively; risks of oral clefts were 9.3 (6.2 to 12.4) versus 10.6 (8.4 to 12.8) per 10 000 pregnancies, respectively. The adjusted relative risk after fine stratification of the propensity score was 1.30 (1.09 to 1.56) for musculoskeletal malformations, 1.04 (0.70 to 1.55) for conotruncal malformations, and 0.91 (0.61 to 1.35) for oral clefts overall. Based on cumulative doses of fluconazole, the adjusted relative risks for musculoskeletal malformations, conotruncal malformations, and oral clefts overall were 1.29 (1.05 to 1.58), 1.12 (0.71 to 1.77), and 0.88 (0.55 to 1.40) for 150 mg of fluconazole; 1.24 (0.93 to 1.66), 0.61 (0.26 to 1.39), and 1.08 (0.58 to 2.04) for more than 150 mg up to 450 mg of fluconazole; and 1.98 (1.23 to 3.17), 2.30 (0.93 to 5.65), and 0.94 (0.23 to 3.82) for more than 450 mg of fluconazole, respectively. CONCLUSIONS Oral fluconazole use in the first trimester was not associated with oral clefts or conotruncal malformations, but an association with musculoskeletal malformations was found, corresponding to a small adjusted risk difference of about 12 incidents per 10 000 exposed pregnancies overall.

Abstract
The neural crest (NC), discovered by Wilhelm His 150 years ago, gives rise to a multipotent migratory embryonic cell population that generates a remarkably diverse and important array of cell types during the development of the vertebrate embryo. These cells originate in the neural plate border (NPB), which is the ectoderm between the neural plate and the epidermis. They give rise to the neurons and glia of the peripheral nervous system, melanocytes, chondrocytes, smooth muscle cells, odontoblasts and neuroendocrine cells, among others. Neurocristopathies are a class of congenital diseases resulting from the abnormal induction, specification, migration, differentiation or death of NC cells (NCCs) during embryonic development and have an important medical and societal impact. In general, congenital defects affect an appreciable percentage of newborns worldwide. Some of these defects are caused by teratogens, which are agents that negatively impact the formation of tissues and organs during development. In this review, we will discuss the teratogens linked to the development of many birth defects, with a strong focus on those that specifically affect the development of the NC, thereby producing neurocristopathies. Although increasing attention is being paid to the effect of teratogens on embryonic development in general, there is a strong need to critically evaluate the specific role of these agents in NC development. Therefore, increased understanding of the role of these factors in NC development will contribute to the planning of strategies aimed at the prevention and treatment of human neurocristopathies, whose etiology was previously not considered.

Abstract
BACKGROUND Oral fluconazole is used to treat vulvovaginal candidiasis during pregnancy. However, there are concerns regarding the pregnancy outcomes following exposure to fluconazole. OBJECTIVES To evaluate the pregnancy outcomes associated with exposure to oral fluconazole during the first trimester of pregnancy. SEARCH STRATEGY A systematic literature search was conducted to identify relevant studies published from inception until April 2019. SELECTION CRITERIA Relevant English-language citations using the terms oral fluconazole and pregnancy in humans. DATA COLLECTION Two reviewers independently abstracted data and assessed study quality. MAIN RESULTS Oral fluconazole use during the first trimester of pregnancy was marginally associated with an increased risk of congenital malformations (odds ratio [OR] 1.09, 95% CI 0.99-1.2, P = 0.088; n = 6 studies), whereas in the subgroup analysis, this association existed only for high-dose users (>150 mg) (OR 1. 19, 95% CI 1.01-1.4, P = 0.039; n = 2). Exposure to fluconazole also increased the risk of heart malformations (OR 1.31, 95% CI 1.09-1.57, P = 0.003; n = 4), cardiac septal defects (OR 1.3, 95% CI 1.1-1.67, P = 0.047; n = 3), and tetralogy of Fallot (OR 3.39 95% CI 1.71-6.74, P < 0.001; n = 2) in the offspring. In addition, exposure to fluconazole was significantly associated with an increased risk of spontaneous abortion (OR 1.99, 95% CI 1.38-2.88, P < 0.001; n = 3). CONCLUSIONS Oral fluconazole use during the first trimester of pregnancy appears to be associated with heart malformations and spontaneous abortion, but a causal link cannot be proven. TWEETABLE ABSTRACT Oral fluconazole during the first trimester of pregnancy may be associated with unfavourable pregnancy outcomes.

Abstract
BACKGROUND While topical azoles are the first-line treatment for fungal infections, oral fluconazole is frequently used during pregnancy. We aimed to assess the effect of exposure to low and high doses of fluconazole during pregnancy on the occurrence of spontaneous abortions, major congenital malformations and stillbirths. METHODS Within the Quebec Pregnancy Cohort (1998-2015), we identified women exposed to low- (≤ 150 mg) and high-dose (> 150 mg) fluconazole, and women who were not exposed. For each case of spontaneous abortion or stillbirth, up to 5 controls were randomly selected using an incidence density sampling method matched on gestational age at diagnosis of spontaneous abortion or stillbirth (index date) and the year of the last menstrual period. For cases of major congenital malformation, we considered all liveborn babies as controls. Generalized estimation equation models were used to analyze the 3 main outcomes separately. RESULTS Within a cohort of 441 949 pregnancies, 320 868 pregnancies were included in the analyses of spontaneous abortions, 226 599 of major congenital malformations and 7832 of stillbirths. Most (69.5%) women exposed to fluconazole in pregnancy received the common single therapeutic dose of 150 mg (low dose); the remainder received a dose of > 150 mg (high dose). Use of oral fluconazole during early pregnancy was associated with an increased risk of spontaneous abortion compared with no exposure (adjusted odds ratio [OR] for 345 cases exposed to low-dose treatment 2.23, 95% confidence interval [CI] 1.96-2.54; adjusted OR for 249 cases exposed to high-dose treatment 3.20, 95% CI 2.73-3.75). Exposure to fluconazole during the first trimester did not increase the risk of overall major congenital malformations; however, exposure to a high dose during the first trimester was associated with an increased risk of cardiac septal closure anomalies (adjusted OR 1.81, 95% CI 1.04-3.14; 13 exposed cases) compared with no exposure. No association was found between exposure to fluconazole during pregnancy and the risk of stillbirth. INTERPRETATION Any maternal exposure to fluconazole during pregnancy may increase risk of spontaneous abortion and doses higher than 150 mg during the first trimester may increase risk of cardiac septal closure anomalies.

Abstract
The aim of this work was to evaluate the Ascidian Embryo Teratogenicity assay (AET) as new alternative invertebrate model to test the developmental effects of the co-exposure to ethanol and fluconazole. Ciona intestinalis embryos were exposed to the azolic fungicide fluconazole, (FLUCO, 7.8-250μM), to ethanol (Eth, 0.01-0.5%) and to their mixture (0.01% Eth+FLUCO 7.8-250μM) from neurula to larval stage. At the end of the exposure period, larvae were morphologically evaluated and benchmark analysis performed by using the PROAST modelling software. Both compounds were teratogenic in a concentration-related manner, particularly affecting the pigmented organs. The co-exposure to Eth enhanced the effects of FLUCO, the additive hypothesis was not rejected by the modelling. The results demonstrated that AET could be considered a good vertebrate-free alternative model for toxicological investigation in embryos.

Abstract
BACKGROUND Low-dose fluconazole is used commonly to treat vulvovaginal candidiasis, a condition occurring frequently during pregnancy. Conflicting information exists on the association between low-dose fluconazole use among pregnant women and the risk of major birth defects. OBJECTIVE We used data from the National Birth Defects Prevention Study to examine this association. STUDY DESIGN The National Birth Defects Prevention Study is a multisite, population-based, case-control study that includes pregnancies with estimated delivery dates from 1997 to 2011. Information on fluconazole use in early pregnancy was collected by self-report from 31,645 mothers of birth defect cases and 11,612 mothers of unaffected controls. Adjusted odds ratios and 95% confidence intervals were estimated for birth defects with 5 or more exposed cases; crude odds ratios and exact 95% confidence intervals were estimated for birth defects with 3-4 exposed cases. RESULTS Of the 43,257 mothers analyzed, 44 case mothers and 6 control mothers reported using fluconazole. Six exposed infants had cleft lip with cleft palate, 4 had an atrial septal defect, and each of the following defects had 3 exposed cases: hypospadias, tetralogy of Fallot, d-transposition of the great arteries, and pulmonary valve stenosis. Fluconazole use was associated with cleft lip with cleft palate (odds ratio = 5.53; confidence interval = 1.68-18.24) and d-transposition of the great arteries (odds ratio = 7.56; confidence interval = 1.22-35.45). CONCLUSIONS The associations between fluconazole and both cleft lip with cleft palate and d-transposition of the great arteries are consistent with earlier published case reports but not recent epidemiologic studies. Despite the larger sample size of the National Birth Defects Prevention Study, fluconazole use was rare. Further investigation is needed in large studies, with particular emphasis on oral clefts and conotruncal heart defects.

Abstract
Antifungal prescription remains a challenge in pregnant women because of uncertainties regarding fetal toxicity and altered maternal pharmacokinetic parameters that may affect efficacy or increase maternal and fetal toxicity. We present updated data reviewing the available knowledge and current recommendations regarding antifungal prescription in pregnancy. Amphotericin B remains the first-choice parenteral drug in spite of its well-established toxicity. Topical drugs are used throughout pregnancy because of limited absorption. Recent data have clarified the teratogenic effect of high-dose fluconazole during the first trimester and provided reassuring cumulative data regarding its use at a single low dose in this key period. Recent data have also provided additional safety data on itraconazole and lipidic derivatives of amphotericin B. Regarding newer antifungal drugs, including posaconazole and echinocandins, clinical data are critically needed before considering prescription in pregnancy.

Abstract
The embryonic stem cell test (EST) has been shown to be a promising in vitro method for the prediction of developmental toxicity. In our previous studies, we demonstrated that the implementation of gene expression analysis in the EST may further improve the identification of developmental toxicants. In the present study, we investigated if gene expression profiling could be used to discriminate compound classes with distinct modes of action (MoA) using the EST protocol. Gene expression data of our previous study were used and were analyzed of embryonic stem cell (ESC) differentiation cultures exposed to six compounds belonging to two classes with distinct MoA, namely phthalates and triazoles. We used three approaches to study class-characteristic gene regulation that may be useful for discrimination of compound classes. First, at the individual gene level, gene signatures characteristic for each class were identified that successfully discriminated both classes using principal component analysis. Second, at the functional level, enriched gene ontology (GO) biological processes showed their usefulness for class discrimination via hierarchical clustering. Third, two previously identified gene sets, which we designed to predict developmental toxicity, appeared successful in separating phthalate from triazole compounds. In summary, we established the possibility to discriminate between compound classes in the EST system using three different specific transcriptomics-based approaches. Differential gene expression information specific for the class of compound under study may be employed to optimize prioritization of compounds within that class for further testing.

Abstract
Imazalil (IMA) is a fungicide that is used extensively in fruit plantations and post-harvest treatments. IMA is suspected to produce craniofacial malformations in vertebrates and scarce data are available about its genotoxicity. Therefore, toxicity tests on embryogenesis of zebrafish (Danio rerio) and genotoxicity biomonitoring assays on human lymphocytes were performed to assess the effects of IMA. For this aim, zebrafish embryos were continually exposed, from 0.5 to 144 h post-fertilization, to a range of concentrations (5, 10, 20, 50 and 100 µM). IMA (0 to 672 µM) were also applied to the whole-blood cultures from two persons. We used chromosomal aberrations (CA) and micronucleus (MN) tests to examine DNA damage by IMA in human peripheral lymphocytes. The fungicide significantly altered zebrafish development even at low concentrations and its effects were dose-dependent. Results of the experiment indicated that IMA concentrations of 10 µM and above negatively affected embryo survival and hatching success. Morphological analysis uncovered a large suite of abnormalities such as less melanin pigmentation, wavy notochord, crooked trunk, tail defect and cardiac edema. The cytogenetic results clearly showed that IMA caused increases of the frequencies of the structural chromosomal aberrations and the rates of MN as compared to controls in a dose-dependent manner. In conclusion, the present findings are of importance in the assessment of the potential risk of fungicides as IMA on aquatic ecosystems and humans.

Abstract
Imazalil (IMA) is a fungicide that is used extensively in fruit plantations and post-harvest treatments, but has teratogenic effects on vertebrate development, possibly due to the perturbation of retinoic acid (RA) levels in the embryo. Ascidians are sessile marine invertebrate chordates that develop through a tadpole larva, with a body plan that shares basic homologies with vertebrates. In this work, we tested the effects of IMA on the development of the solitary ascidian Ciona intestinalis by treating two-cell stage embryos with a range of concentrations (0.1, 0.5, 1, 2.5, 5, 10, 20 and 50microThe fungicide significantly altered ascidian development even at low concentrations and its effects were dose-dependent. Probit analysis revealed that the median lethal concentration, LC(50), was 4.87microM and the median teratogenic concentration, TC(50), was 0.73microM. Larvae developing from embryos exposed to IMA showed malformations of the anterior structures, which became more severe as IMA concentration increased. In particular, the anterior nervous system and the sensory vesicle were reduced, and the pigmented organs (the ocellus and the otolith) progressively lost their pigmentation. The larval phenotype induced by 5microM IMA exposure was further characterized by means of molecular analysis, through whole mount in situ hybridization with probes for genes related to the nervous system: Ci-Otp, Ci-GAD, Ci-POU IV, which are markers of the anterior neuro-ectoderm, the central nervous system and the peripheral nervous system respectively, and Ci-Hox-1, a gene specifically activated by RA, and Ci-Aldh2, a gene for aldehyde dehydrogenase, which is involved in RA synthesis. The altered expression of Ci-Otp, Ci-GAD, Ci-POU IV in 5microM IMA-exposed larvae compared to control larvae showed that this fungicide could affect the differentiation of the anterior nervous system, particularly of the sensory vesicle neurons. Recent studies suggest a similarity between IMA- and RA-induced phenotypes in tunicates, indicating that triazoles may also alter RA metabolism in ascidians. The observed Ci-Hox-1 and Ci-Aldh2 expression in control and treated larvae did not allow a direct link between IMA teratogenic potential and RA-dependent morphogenesis to be identified. It is likely that the fungicidal teratogenic mechanism involved RA signalling but that its effects on ascidian development depend on a more complex mechanism.

Abstract
Disruption of embryonal retinoic acid homeostasis has been postulated to represent an etiological factor involved in the onset of fluconazole-induced teratogenesis. In the present study the impact of a teratogenic pulse of fluconazole on the gene expression of cytochrome P450 (CYP) 26 isoforms, which plays a central role in maintaining proper retinoic acid levels by mediating its degradation, was investigated. ICR pregnant mice were orally administered with 0 (vehicle) or 700mg/kg of fluconazole on gestation day 8. Embryos were collected 12, 24 and 48h after treatment. Quantitative real-time reverse-transcription polymerase chain reaction (quantitative real-time RT-PCR) assay was used to quantify the mRNA expression of CYP26a1, CYP26b1 and CYP26c1 in embryos. As result, fluconazole exposure was associated to an up-regulation of CYP26a1, CYP26b1, whereas no significant change was identified for the CYP26c1 isoform. This study demonstrates the capacity of fluconazole to alter CYP26 gene expression in mouse embryos.

Abstract
OBJECTIVE This study examined whether first-trimester antifungal drug use was associated with the risk of selected birth defects. STUDY DESIGN Subjects were participants in a case-control study, the National Birth Defects Prevention Study, with singleton deliveries from 1997 to 2003. Based on maternal interviews, first-trimester antifungal drug use was compared between 7047 cases with isolated defects and 4774 nonmalformed controls using unconditional logistic regression. RESULTS Risk was elevated for hypoplastic left heart syndrome (odds ratio, 2.30; 95% confidence interval, 1.04, 5.06) but not for other cardiovascular defects. An increased risk of 1.88 was observed for diaphragmatic hernia but was not statistically significant. Estimates approximated unity for neural tube defects, oral clefts, anorectal atresia, hypospadias, and craniosynostosis. CONCLUSION First-trimester antifungal drug exposure was not strongly associated with the risk of most birth defects, but further studies should examine the preliminary results of an association with hypoplastic left heart syndrome.

Abstract
Fluconazole (FLUCO) is an azole derivative used to treat fungal and yeast infections. Embryotoxicity tests on the ascidian Phallusia mammillata were performed to evaluate the effects of this drug. FLUCO proved to have strong consequences on P. mammillata development. Incidence of malformations and of lethality increased in a dose dependent way. Probit analysis showed that FLUCO had a high TI value (Teratogenic Index, LC(50)/TC(50)), thus this substance could be classified as a teratogenic compound for ascidians. Larvae exposed to FLUCO showed a typical phenotype characterized by malformations restricted to the trunk region: the trunk appeared round in shape with flat palps, the sensory vesicle cavity was absent or reduced and the anterior central nervous system failed to correctly differentiate. These anomalies resulted similar to those induced by retinoic acid (RA) treatment. Thus, it could be hypothesized that FLUCO and RA may act with a similar pathogenic mechanism in ascidian larvae, as it has been proposed for mammals.

Abstract
BACKGROUND The triazole derivative, triadimefon (FON), induces branchial arch abnormalities in post-implantation rat embryos cultured in vitro, and cranio-facial malformations in mouse fetuses. Ectopic maxillary cartilage has been also described as a typical FON-related malformation. This work studies the morphogenesis of the ectopic cartilage in rat embryos and fetuses exposed in vivo to FON during the early postimplantation period. METHODS Pregnant rats were treated with 0, 250, and 500 mg/kg FON on Day 9.5 of pregnancy (D9.5) and sacrificed at term (D20), during the early fetal period (D17) or at different embryogenetic periods (D10, D11, D12). The skeleton was examined after stain of bone and cartilage or of cartilage alone respectively at term or at D17. The neural crest cell (NCC) migration and compaction was investigated at D10 and D11 and the cranial nerve organization described at D12. RESULTS Triadimefon is teratogenic in rats under the chosen experimental conditions. The malformations were at the level of the cranio-facial and axial skeleton at term and of the hindbrain nerves in embryos. A NCC abnormal migration and compaction was observed at the level of the first branchial arch: in FON-exposed embryos NCC were detected at the level of both maxillary and mandibular processes, whereas control embryos showed the immunostained tissue only at the level of the mandibular bud. CONCLUSIONS The pathogenic pathway, proposed to explain the ectopic cartilage, is the displacement of part of the NCC-derived tissues at the maxillary region of the first branchial arch.

Abstract
Azole compounds are fungicides used in agriculture and in clinical area and are suspected to produce craniofacial malformations in vertebrates. Toxicity tests on sperm viability, fertilization and embryogenesis of the solitary ascidian Phallusia mammillata were performed to evaluate the effects of two azole derivatives, Imazalil and Triadimefon. Ascidian (Chordata, Ascidiacea) embryos and larvae could provide biological criteria for seawater quality standards because the larvae are lecitotrophic and have a short pelagic period, allowing to run the larval toxicity tests over a short period of time. Imazalil and Triadimefon proved to have strong consequences on P. mammillata. They could influence the reproductive rate of the animal exerting their effects at different levels: acting as spermiotoxic agents, inhibiting fertilization and impairing embryological development. Fertilization rate significantly decreased after 30min exposure of sperm to 25microM Imazalil (P<0.0001) and after exposure of both gametes to 50microM Imazalil (P<0.05) and 1mM Triadimefon (P<0.0001) as compared to controls. Malformations caused by exposure of embryos to both substances were dose dependent. Imazalil median teratogenic concentration (TC50 concentration, the concentration that resulted in 50% malformed larvae) value was 0.67microM and median lethal concentration (LC50, the concentration that resulted in 50% embryos dead before completing the development) value was 10.23microM while for Triadimefon TC50 value was 29.56 and LC50 value was 173.7microM. Larvae developed from embryos treated with Imazalil and Triadimefon showed alterations of the anterior structures of the trunk: papillary nerves and the anterior central nervous system failed to correctly differentiate, as showed by immunostaining with anti-beta-tubulin antibody. Comparing the anomalies caused by retinoic acid, reported in a previous study, it was possible to hypothesize that malformations induced by Imazalil and Triadimefon could be due to a perturbation of the endogenous retinoid content, as it has been proposed for mammals. Ascidians proved to be good models to study the toxic effects of pesticides since they offered both the convenience of working with an invertebrate species and the tissue sensitivity to chemical compound comparable to vertebrates.

Abstract
The main aim of the study was to identify the critical periods of susceptibility for itraconazole-mediated teratogenesis in the mouse. Pregnant ICR (CD-1) mice received a single oral administration of itraconazole at 50 mg/kg b.w., 150 mg/kg b.w. or 250 mg/kg b.w. on gestation day 8, 9, 10, 11 or 12. Control animals were administered with vehicle on gestation days 8-12. The gestational outcome was evaluated near term, on gestation day 18. Treatment-related morphological findings, as they can be evaluated by external, visceral and skeletal examination, mainly included cleft palate, limb defects and axial skeletal malformations. Cleft palate and limb defects resulted after single exposures between gestation days 9 and 11, with a tendency toward maximal response on gestation day 10. Significant incidences of axial skeletal defects were seen exclusively on gestation days 8 and 9. Exposure on gestation day 12 did not yield significant teratogenic responses. Cleft palate was the most sensitive teratogenic response, being the only developmental lesion associated to exposure to itraconazole at 150 mg/kg b.w.

Abstract
Triazole fungicides are used in medicine as well as in agricultural treatment of mycoses. The pharmacological mechanism is related to the inhibition of CYP enzymes involved in the formation of the fungal walls. A similar inhibition of human CYP enzymes has been suggested as the cause of triazole side effects in humans. An important role of some CYP isoforms (CYP26 isoforms) expressed during mammalian development is the catabolism of retinoic acid, a known morphogen in vertebrates and invertebrates. The adverse effects on morphogenesis, observed after exposure of mammalian, amphibian and ascidiacea, are compared to the reported effects of triazole in humans. The possible pathogenic pathway in triazole-related teratogenesis is discussed on the basis of different experimental approaches.

Abstract
Like triazole-derivatives, imidazole-derivatives exert their antifungal and toxicological properties by inhibiting P450 enzymes (Cyps). At the embryonic level, Cyp enzymes are involved also in the catabolism of the retinoic acid. Specific effects of triazole-derivatives have been reported on developing rodent embryos, and were correlated to an imbalance of the retinoid homeostasis. The aim of this work was to investigate if imidazole-derivatives are able to induce specific malformations similar to those observed after triazole-derivative exposure. Post implantation rat embryos were exposed in vitro to 1,000 microM Imidazole and to 5-100 microM of the imidazole-derivatives Ketoconazole and Enilconazole. After 48 h in culture, the embryos exposed to the imidazole-derivatives showed specific malformations, quite similar to those observed after triazole-derivative exposure. The common dysmorphogenic effects of the azole-derivatives of the two classes could be due to the inhibition of retinoid catabolism. From this point of view, the contemporaneous exposure to these substances or their therapeutic use could be considered as potentially dangerous for human conceptuses.

Abstract
Triazole-derivatives alter the pharyngeal apparatus morphogenesis of rodent embryos cultured in vitro. The hindbrain segmentation and the rhombencephalic neural crest cell (NCCs) migration are altered by Fluconazole exposure in vitro. The aim of the present work is to identify if a common pathogenic pathway is detectable also for other molecules of this class of compounds. 9.5 days post coitum (d.p.c.) old rat embryos were exposed in vitro to the teratogenic concentrations of Flusilazole, Triadimefon and Triadimenol and cultured for 24, 48 or 60 h. The expression and localisation of Hox-b1 and Krox-20 proteins (used as markers for hindbrain segmentation) were evaluated after 24 h of culture. The localisation and distribution of NCC was evaluated after 24, 30 and 48 h of culture. The morphology of the embryos was analysed after 48 h, while the branchial nerve structures were evaluated after 60 h of culture. Hindbrain segmentation and NCC migration alteration as well as pharyngeal arch and cranial nerve abnormalities were detected after exposure of the tested molecules. A common severe teratogenic intrinsic property for the tested molecules of this chemical class has been found, acting through alteration of the normal hindbrain developmental pattern.

Abstract
Triadimefon and triadimenol, fungicides used in agriculture, are suspected of producing craniofacial malformations. As the results of FETAX analysis showed that Triadimefon was highly teratogenic, we studied the action of these triazoles on the development of the branchial apparatus in Xenopus, using early molecular markers and analysis of the cartilaginous-muscular elements of tadpoles. Teratogenic effects were observed, after exposure at the neurula stage, at the level of cartilages and muscles of the 1st and 2nd branchial arches. By in situ hybridization, we observed that in exposed specimens the territories of the branchial arches are perturbed. From these results, we considered the craniofacial malformations related to the influence of triazoles on the differentiation of branchial arches. Comparing the anomalies caused by triazoles and by retinoic acid (RA) led us to the conclusion that triazoles can affect endogenous RA content, as has been shown for mammals.

Abstract
The potential of in utero exposure to fluconazole to initiate teratogenesis was analyzed in ICR (CD-1) mice. Developmental phase specificity was determined by treating mice with single oral doses of 700 mg/kg on gestational day 8, 9, 10, 11, or 12. Control animals received vehicle on gestational days 8-12. Gestational day 10 was identified as the phase of maximal sensitivity for induction of cleft palate, the predominant teratogenic effect induced by fluconazole, with 50% of fetuses exposed on this developmental phase being affected. After treatments on gestational day 8, 9, 11, or 12, cleft palate occurred with lower frequencies: 12, 21, 28.7, and 2.7%, respectively. Examination of skeletal morphology revealed anomalies of the middle ear apparatus in 15% of the fetuses that were exposed on gestational day 8. Dysmorphic tympanic ring and absence of the incus were the more common ear anomalies recorded. Reduced humeral length was noted in 22% of fetuses that were exposed on gestational day 10. Dose-response relationship was investigated by treating animals with 0 (vehicle), 87.5, 175, or 350 mg/kg on gestational day 10, coincident with the phase of peak teratogenic sensitivity. Besides showing that fluconazole operates under a strict dose-response mechanism, the study identified 175 mg/kg as the lowest observed adverse effect level for cleft palate induction, with 7.6% of the exposed fetuses being affected.

Abstract
BACKGROUND Triadimefon is an antifungal derived from triazole. In in vitro whole-rodent embryo cultures, triazole-derivatives showed specific teratogenic effects at the branchial apparatus. The aim of the present work was to test in vivo triadimefon (FON), in order to verify a relationship between triazole exposure, embryonic abnormalities, and/or fetal malformations. METHODS Pregnant CD-1 mice were treated with 0-300 mg/kg FON by gavage on day 8 post coitum (p.c.) at 10:00 AM, and sacrificed on day 8 p.c. at 1:00 PM, on day 9 p.c. at 10:00 AM, on day 10 p.c. at 10:00 AM, and at term of gestation (day 18 p.c.). At midgestation, the embryos were processed for specific immunostainings to visualize the hindbrain segmentation (day 8 p.c.) and the neural crest cell migration (days 8 and 9 p.c.). Fetuses explanted at term were all processed for skeletal examination after double-staining of osseous and cartilaginous tissues. RESULTS At midgestation, the immunostaining of rhombomeres 3 and 5 showed a light scattering of the immunostained areas; the neural crest cell migration was unaffected, but their localization at the branchial arch level was abnormal. At term, several severe malformations were observed at the craniofacial and at the axial skeletal level. Ectopic cartilage was observed at the upper jaw. CONCLUSIONS Triadimefon is teratogenic. The observed craniofacial malformations could be explained by an alteration of the rhombomeric organization and neural crest migration to the branchial arches; the axial abnormalities could be explained by the abnormal segmental identity specification.

Abstract
Fluconazole (FLUCO) and retinoic acid (RA) can perturb morphogenesis of the branchial apparatus in rodent embryos exposed in vitro. The aim of the present study was to compare the effects induced by in vitro exposure to FLUCO or to RA on rhombomere organisation, neural crest cell (NCC) migration and cranial nerve differentiation using specific antibodies. For this purpose 9.5 d.p.c. rat embryos were exposed to teratogenic concentrations of FLUCO or RA; another group was exposed to no-effect concentrations of both agents. Expression of Hox-b1 and Krox20 (markers of specific rhombomeres) was altered after FLUCO and RA exposure. Furthermore, FLUCO and RA showed a synergistic effect. These results suggest that the observed branchial abnormalities are due to anomalous NCC migration related to incorrect organisation of specific rhombomeres.
