CHICAGO—Once methotrexate enters a cell through the reduced folate carrier (RFC), which thinks it is picking up folate, the drug is polyglutamated. It is this polyglutamate methotrexate that provides the actual clinical effect. These methotrexate polyglutamate “species” are added and lost over time, but it’s a slow process. What difference does it make whether a… [Read More]
Research has found that taking adalimumab plus methotrexate is effective for patients with juvenile idiopathic arthritis-associated uveitis. However, these patients may also experience an increased incidence of adverse and serious adverse events compared with those taking only methotrexate…... [Read More]
MADRID—Tofacitinib (a JAK inhibitor) used with methotrexate (MTX) is not inferior to adalimumab (a TNF inhibitor) in rheumatoid arthritis (RA) patients who’ve had an inadequate response to MTX alone, according to results of a Phase 3B/4 trial presented in a session at the Annual European Congress of Rheumatology (EULAR). The findings came in a one-year… [Read More]
Highlights from the 2017 EULAR Congress MADRID—Tofacitinib (a JAK inhibitor) used with methotrexate (MTX) is not inferior to adalimumab (a TNF inhibitor) plus MTX in rheumatoid arthritis (RA) patients who’ve had an inadequate response to MTX alone, according to results of a Phase 3B/4 trial presented in a session at the Annual European Congress of… [Read More]
NEW YORK (Reuters Health)—Adding prednisone to methotrexate for early rheumatoid arthritis (RA) results in a lower initiation rate of a biologic, better radiographic outcomes and no steroid-related side effects, researchers in the Netherlands say. Although biological disease-modifying anti-rheumatic drugs (bDMARDs) have led to better control of RA and improved functioning and quality of life, they… [Read More]
NEW YORK (Reuters Health)—Temporarily withholding methotrexate (MTX) can improve the efficacy of seasonal influenza vaccination in patients with rheumatoid arthritis (RA), according to a new randomized clinical trial. Response was strongest in patients who discontinued MTX for two weeks before and two weeks after receiving the flu shot, Dr. Eun Bong Lee of Seoul National… [Read More]
The FDA has approved a new formulation of methotrexate designed as an oral solution for pediatric patients. The agency has also recently introduced age restrictions for codeine and tramadol for children under age 12, citing their risks for slowed or difficult breathing and death…... [Read More]
Disease outcomes in rheumatoid arthritis (RA) have improved dramatically since the introduction of biologic agents and improved treatment strategies. Nevertheless, the majority of patients still require prolonged, if not lifelong, therapy. Therefore, the ultimate goal would be to prevent RA. This study analyzed the effect of a one-year course of methotrexate in high-risk UA patients (studied in a previous trial) after post-randomization exclusion of patients without a high risk of developing RA…...

NEW YORK (Reuters Health)—In patients taking methotrexate for rheumatoid arthritis (RA), moderate alcohol consumption – that is, no higher than existing U.K. guidelines for the general population – was not associated with an increased risk of transaminitis, researchers say. The study is both the largest to examine alcohol and methotrexate (MTX) and the first to… [Read More]
NEW YORK (Reuters Health)—A father’s exposure to methotrexate 90 days or less before conception “should not be of major concern,” researchers say. Prepregnancy paternal methotrexate exposure appears to confer no increased risk of major or minor congenital malformation, stillbirth or preterm birth in his offspring, their study found. Methotrexate is a first-line therapy for rheumatoid… [Read More]
