Common Therapy for Rheumatoid Arthritis Reduces Risk of DeathTaking methotrexate—a commonly prescribed anti-inflammatory medication—may reduce the risk of death among patients with rheumatoid arthritis (RA), according to recently-published research in the journal Arthritis and Rheumatism. The study, which was funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), echoes earlier research that found that this standard treatment has protective effects among RA patients.
RA is a painful, chronic condition that involves persistent inflammation in the body, and is sometimes linked with other life-threatening diseases. Previous studies have suggested that treatment with methotrexate is associated with a lower risk of death among patients with RA. However, it is unclear if this reduced risk of death is attributable to the use of methotrexate itself, or if it is a reflection of other variables, such as overall health differences in the types of patients who are prescribed methotrexate. In addition, over the last 20 years, dosage levels have increased, as well as duration of use, prompting the need for updated information about the medication’s potential effects.
The significant relationship between the drug and improved survival rates also indicates that it may potentially have advantages beyond treating RA symptoms, such as reduced risk of cardiovascular problems, according to the researchers. However, the study did not specifically evaluate just how methotrexate works to decrease mortality rates. "Its full impact on overall health remains unclear and warrants further study," cautioned co-author Michael Ward M.D., who is the Acting Chief of the NIAMS Clinical Trials and Outcomes Branch.
