Area of Science:

  • Reproductive toxicology
  • Dermatology
  • Pharmacology

Background:

  • Methotrexate is a common treatment for psoriasis.
  • Accidental exposure during early pregnancy is a concern.
  • Understanding the risks of methotrexate in pregnancy is crucial.

Observation:

  • A 39-year-old woman experienced a spontaneous abortion at 13-14 weeks gestation.
  • She had taken two 15 mg doses of methotrexate for psoriasis around the time of conception.
  • The fetus, examined post-mortem, exhibited no congenital malformations.

Findings:

  • The case highlights a potential association between early methotrexate exposure and spontaneous abortion.
  • Absence of fetal malformations in this instance warrants further investigation.

  • Low-dose methotrexate exposure may have different outcomes than previously understood.

    • Implications:

    • This case necessitates a review of methotrexate prescribing guidelines for women of childbearing potential.
    • Further research is needed to clarify the teratogenic potential of low-dose methotrexate.
    • Enhanced patient counseling regarding methotrexate use and pregnancy is essential.
