Methotrexate, a common drug for rheumatic diseases, has a complex history due to its use in abortions and teratogenic effects. Recent policy changes impact its use and rheumatologists' role in patient reproductive health.
Area of Science:
- Rheumatology
- Pharmacology
- Reproductive Health
Background:
- Methotrexate is a cornerstone medication for various rheumatic diseases, including rheumatoid arthritis, psoriatic arthritis, and systemic lupus erythematosus.
- Initially developed as chemotherapy, its efficacy in inflammatory conditions was recognized early on.
- Methotrexate also has abortifacient properties and is a known teratogen, posing risks during pregnancy.
Purpose of the Study:
- To examine the implications of recent US abortion policy changes on methotrexate use in rheumatology.
- To explore the impact of the Dobbs v. Jackson Women's Health Organization ruling on provider and patient perspectives regarding methotrexate.
- To highlight the evolving role of rheumatologists in addressing patients' sexual and reproductive health concerns.
Main Methods:
- Review of recent literature and data concerning methotrexate use in the context of reproductive health and policy changes.
- Analysis of provider perspectives and patient experiences post-Dobbs ruling.
- Discussion of the intersection of rheumatology, teratogenicity, and abortion policy.
Main Results:
- Recent data indicate that the Dobbs ruling has influenced both healthcare providers and patients concerning methotrexate.
- The teratogenic nature and historical use of methotrexate for abortion complicate its prescription and management.
- There is a growing need for rheumatologists to engage with patients on reproductive health matters.
Conclusions:
- The current landscape of abortion policy in the US presents unique challenges for methotrexate's clinical application.
- Rheumatologists are increasingly expected to navigate complex reproductive health discussions with patients on methotrexate.
- Further research and guidelines are needed to support rheumatologists in managing methotrexate therapy amidst evolving reproductive rights.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
