Methotrexate is an antimetabolite and antifolate agent with antineoplastic and immunosuppressant activities. Methotrexate binds to and inhibits the enzyme dihydrofolate reductase, resulting in inhibition of purine nucleotide and thymidylate synthesis and, subsequently, inhibition of DNA and RNA syntheses. Methotrexate also exhibits potent immunosuppressant activity although the mechanism(s) of actions is unclear.
Methotrexate is approved by the Food and Drug Administration (FDA) to be used by itself to treat the following types of gestational trophoblastic tumors, Chorioadenoma destruens, Choriocarcinoma, Hydatidiform mole. Methotrexate is also approved to be used alone or with other drugs to treat acute lymphoblastic leukemia (ALL) that has spread to the central nervous system (CNS) or to keep it from spreading there, and to treat the following, breast cancer, certain types of head and neck cancer, lung cancer, advanced non-Hodgkin lymphoma (NHL), advanced mycosis fungoides (a type of cutaneous T-cell lymphoma), osteosarcoma that has not spread to other parts of the body, following surgery to remove the primary tumor. Methotrexate is also approved to treat the following non-cancer conditions, rheumatoid arthritis, severe psoriasis.

Repeat treatment with corticosteroid injections improved vision in people with persistent or recurrent uveitis-related macular edema better than two other therapies, according to results from a clinical trial funded by the National Eye Institute.
The increased cardiovascular risks in RA include acute coronary syndromes (ACS). The extent to which DMARD-induced remission could reduce the risk of ACS in RA versus rates in the general population – and whether there are DMARD-specific beneficial effects on ACS risk – remain unknown.
Studies on the long-term consequences of COVID-19 (long-COVID) in patients with inflammatory rheumatic diseases (iRD) are scarce.
Rheumatoid arthritis (RA) is an autoimmune disease characterized by joint deterioration. The clinical outcomes of patients with active RA can be improved using anti-rheumatic medications, such as methotrexate (MTX).
Crohn's disease is a lifelong inflammatory bowel disease (IBD) that is characterized by swelling in the lining of the digestive tract, causing severe diarrhea, abdominal pain, and rectal bleeding.
The vascular smooth muscle cells that normally give blood vessel walls strength and flexibility proliferate and become destructive in pulmonary hypertension, a typically rapidly progressing condition that makes it hard to get blood inside our lungs and oxygen to our bodies.
In a recent study posted to the medRxiv* preprint server, researchers assessed the impact of third and fourth coronavirus disease 2019 (COVID-19) vaccination doses on immunity against COVID-19 among immunocompromised adult patients.
The immunosuppressive drug methotrexate (MTX) can be linked to an elevated risk of three types of skin cancer, a new study by University of Gothenburg researchers shows.

Late-breaking research reveals a major treatment advance for adults with newly diagnosed B lineage acute lymphoblastic leukemia (ALL).
People with rheumatoid arthritis are at increased risk of cardiovascular (CV) disease, with studies indicating an approximate 50 percent increase in risk of CV events such as heart attack and stroke.
Soon after cholesterol and fat start depositing on the lining of the blood vessels that supply your heart, the smooth muscle cells that give the blood vessels strength and flexibility start to get bigger and multiply.
Oregon State University scientists have produced a proof of concept for a new and better way of caring for women facing the life-threatening situation of ectopic pregnancy, which occurs when a fertilized egg implants somewhere other than the lining of the uterus.
Since their first publication in 2010, the EULAR recommendations for the use of disease-modifying anti-rheumatic treatments (DMARDs) in people with RA have become a most important publication in the field, and their updates are relied upon by many healthcare professionals, professional organizations and other stakeholders to offer an up-to-date and robust analysis on an optimal approach to the application of available treatment options in clinical practice.
New research presented this week at ACR Convergence 2022, the American College of Rheumatology's annual meeting, showed that discontinuing methotrexate for one week after seasonal influenza vaccination provided the same seroprotection as a two-week discontinuation period in patients with rheumatoid arthritis.
Findings of a new study depicted that fully vaccinated patients suffering from systemic autoimmune rheumatic diseases harbor a lower propensity to developing long COVID symptoms compared to SARDs patients who are not fully vaccinated.
