[Isotretinoin (RoAccutane) embryopathy. A case report].
    Journal de gynecologie, obstetrique et biologie de la reproduction, 1995, Volume: 24, Issue:5

    Retinoids are synthetic vitamin A derivatives, particularly used in dermatology. Their prescription in women of childbearing age can cause, if pregnancy occurs, a serious malformative embryopathy, mainly involving external ear, brain and heart. A neonatal case caused by isotretinoin (RoAccutane) emphasizes the clinical and epidemiological data concerning this embryopathy. The aetiopathological hypothesis of an interaction between isotretinoin and Hox genes is advanced. Prophylactic measures are difficult since neonatal reported cases are uncommon, but antenatal exposition to this strong teratogenic agent results in multiple spontaneous abortions or pregnancy interruptions.

Isotretinoin and pregnancy.
    Journal of the American Academy of Dermatology, 1984, Volume: 10, Issue:5 Pt 1

    Approximately 120,000 women of childbearing age used isotretinoin in the first 16 months after its release for the treatment of cystic acne. In September, 1983, the American Academy of Dermatology requested its members to relate the outcome of pregnancies of women inadvertently exposed to isotretinoin ( Accutane ) during pregnancy to its Adverse Drug Reaction Reporting System ( ADRRS ). Of nine pregnancies reported, seven ended in spontaneous abortion or the birth of an infant with birth defects. Of thirty-five pregnancies with isotretinoin exposure reported to the ADRRS or the U.S. Food and Drug Administration, twenty-nine (83%) resulted in spontaneous abortion or infants with birth defects. The most frequently reported severe birth defects involved the central nervous system (microcephaly or hydrocephalus) and the cardiovascular system (anomalies of the great vessels). Microtia or absence of external ears were also noted in a majority of cases. These findings illustrate the usefulness of specialty-based reporting of adverse drug effects and emphasize the teratogenic risk of isotretinoin in humans. Physicians need to fully and carefully inform women of childbearing age of these risks.

Retinoic acid embryopathy.
    The New England journal of medicine, 1985, Oct-03, Volume: 313, Issue:14

    Retinoic acid, an analogue of vitamin A, is known to be teratogenic in laboratory animals and has recently been implicated in a few clinical case reports. To study the human teratogenicity of this agent, we investigated 154 human pregnancies with fetal exposure to isotretinoin, a retinoid prescribed for severe recalcitrant cystic acne. The outcomes were 95 elective abortions, 26 infants without major malformations, 12 spontaneous abortions, and 21 malformed infants. A subset of 36 of the 154 pregnancies was observed prospectively. The outcomes in this cohort were 8 spontaneous abortions, 23 normal infants, and 5 malformed infants. Exposure to isotretinoin was associated with an unusually high relative risk for a group of selected major malformations (relative risk = 25.6; 95 per cent confidence interval, 11.4 to 57.5). Among the 21 malformed infants we found a characteristic pattern of malformation involving craniofacial, cardiac, thymic, and central nervous system structures. The malformations included microtia/anotia (15 infants), micrognathia (6), cleft palate (3), conotruncal heart defects and aortic-arch abnormalities (8), thymic defects (7), retinal or optic-nerve abnormalities (4), and central nervous system malformations (18). The pattern of malformation closely resembled that produced in animal studies of retinoid teratogenesis. It is possible that a major mechanism of isotretinoin teratogenesis is a deleterious effect on cephalic neural-crest cell activity that results in the observed craniofacial, cardiac, and thymic malformations.
