Are azole fungicides a teratogenic risk for human conceptus?
Summary of "Are azole fungicides a teratogenic risk for human conceptus?"
Azole fungicides are widely used in agriculture and in human mycosis. Their antifungal activity is based on their ability to inhibit CYP51, a key enzyme in the formation of fungal wall. Several azole fungicides tested in laboratory animals have been found to possess a common teratogenic potential to induce facial, axial skeleton, and limb defects. The mechanism of the teratogenic effect has been hypotesized to be related to the capability of these substances to alter embryonic retinoic acid catabolism. Although a number of human epidemiological studies were unable to demonstrate a definite relationship between azole exposure during pregnancy and birth defects, some case reports indicate a possible teratogenic effect of high doses of azoles in humans. Because of their common mechanism of action, azole fungicides should be regarded with caution for use in pregnant women.

Medical and Biotech [MESH] Definitions
Chemicals used to destroy pests of any sort. The concept includes fungicides (FUNGICIDES, INDUSTRIAL); INSECTICIDES; RODENTICIDES; etc.
Experimentation on, or using the organs or tissues from, a human or other mammalian conceptus in the postembryonic period, after the major structures have been outlined. In humans, this corresponds to the period from the third month after fertilization until birth.
Experimentation on, or using the organs or tissues from, a human or other mammalian conceptus during the prenatal stage of development that is characterized by rapid morphological changes and the differentiation of basic structures. In humans, this includes the period from the time of fertilization to the end of the eighth week after fertilization.
Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues.
Risk Reduction Behavior
Reduction of high-risk choices and adoption of low-risk quantity and frequency alternatives.
The increasing resistance of several phytopathogenic fungal species to the existing agrochemical fungicides has alarmed to the worldwide scientific community. There is no available methodology to pred...
Purpose: To develop a method for estimating the radiation dose to the conceptus from multidetector computed tomography (CT) of the abdomen and pelvis in pregnant patients during the first 7 weeks of g...
The effect of mixtures of azole fungicides on development of postimplantation rat whole-embryos cultured in vitro has been tested. On the basis of bench mark dose (BMD) modeling of the in vitro effect...
OBJECTIVE: The aim of this study was to examine teratogenic risk perceptions and confidence in the use of medicines in pairs of pregnant women and general practitioners (GPs) through assessments of me...
The current study determined whether the pre-implantation conceptus modified endometrial fatty acid concentrations. Oestrus was synchronized in 14 mature lactating cows and embryos were transferred on...
