This Dangerous Pain Relief Arthritis Drug Linked to Lymphoma Cancer

 

Rheumatoid Pain Relief Arthritis Drug Linked to Lymphoma Cancer For people with rheumatoid arthritis, methotrexate is the treatment of choice in reducing pain and inflammation. But there’s evidence the Pain Relief Arthritis Drug can activate a virus that can increase the risk of Lymphoma Cancer and similar cancers in some patients.The study appears in this month’s issue of the Journal of the National CancerInstitute.A number of reports have linked Pain Relief Arthritis Drug methotrexate with lymphoma and similar cancers of the lymph glands, says senior researcher Shannon C. Kenney,

MD, a microbiologist and infectious disease specialist with the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill. Also, studies have shown that when rheumatoid arthritis patients quit taking methotrexate, their lymphoma went into regression, another sign that the Pain Relief Arthritis Drug directly contributes to the Lymphoma Cancer, she tells WebMD. Some studies have indicated that the Pain Relief Arthritis drug’s immune-weakening effect places people at risk for viral-associated lymphomas.Another factor in this story: Epstein-Barr virus (EBV), a herpes virus that is common among adults.

Some 90% of adults are said to have EBV, which is associated with mononucleosis and other infections — but in the vast majority of people, the virus remains latent, never causing an infection, says Kenney. EBV has also been linked with Lymphoma Cancer.In this newest study, Pain Relief Arthritis Drug methotrexate has been shown to activate latent EBV in cells infected with the virus, Kenney reports.

High levels of circulating infectious particles of the EBV were also found in patients taking methotrexate for rheumatoid arthritis compared with patients taking other immune-weakening Pain Relief Arthritis drugs. Methotrexate and Lymphoma Cancer In a series of laboratory tests involving cells with latent EBV virus, Kenney found that using methotrexate on cells that contained the latent Epstein-Barr virus activated the virus, causing an increase in the release of infectious EBV.“An infectious form of the virus was released from the cells,” she tells WebMD. “We were surprised by that. We had already shown that certain kinds of chemotherapy could induce release of a form of EBV, but none would allow the infectious virus to be released.
