Early Use of Methotrexate Slows Rheumatoid Arthritis

By Pat Anson, PNN Editor

Early treatment with methotrexate can significantly reduce joint pain and inflammation in patients showing early signs of rheumatoid arthritis (RA), according to a new study by Dutch researchers.

First used as a chemotherapy treatment because it prevents cancer cells from dividing, methotrexate became a first-line therapy for RA in the 1980’s because it also acts as an immune system inhibitor. RA is a chronic autoimmune disease in which the body’s own defenses attack joint tissues, causing pain, swelling, inflammation and bone erosion. 

Treatment with methotrexate usually isn’t initiated until RA is diagnosed, but researchers at Leiden University Medical Centre (LUMC) in the Netherlands found that early treatment of patients in the "pre-rheumatic phase" helped slow progression of the disease.

"At present, methotrexate is only prescribed to the patient following a rheumatoid arthritis diagnosis," said lead author Annette van der Helm, PhD, Professor of Rheumatology at LUMC. "But that is too late. By then, the disease is already considered chronic."

Van der Helm and her colleagues enrolled 236 patients who had joint pain and inflammation that could be seen on an MRI. Although RA was suspected, it was not yet confirmed. Half the patients were treated with methotrexate and the other half with a placebo. The effects of the treatments were assessed a year later.

The study findings, published in The Lancet, show that early treatment with methotrexate did not prevent the development of RA, but the diagnosis was delayed. Patients in the methotrexate group also had less pain and morning stiffness than those treated with a placebo. Their physical function was also better and their MRI scans showed less joint inflammation.

"This is an important step towards reducing disease burden for this group of patients," says Van der Helm. "This chronic disease is extremely burdensome to patients and their families. Our study is paving the way toward arthritis prevention."

In 2019, over a million people were prescribed methotrexate in the United States, where it is approved as a treatment for RA, psoriasis and cancer. The drug is also used “off-label” for lupus, migraine, multiple sclerosis, Crohn’s Disease and other autoimmune problems.   

‘Abortion-Inducing Drug’

Ironically, the Dutch study comes at a time when some female patients in the U.S. are losing access to methotrexate because the drug can cause miscarriages and be used to end ectopic pregnancies. After last month’s Supreme Court ruling that overturned Roe vs. Wade, over half the states enacted or implemented abortion limits, including some that specifically list methotrexate as an “abortion-inducing drug.”  

Although the state laws don’t prohibit methotrexate from being used for other purposes, some doctors, pharmacies and insurers have become cautious about prescribing or dispensing the drug. The Arthritis Foundation has heard from several women who’ve had trouble getting methotrexate, including some beyond childbearing age.

“Some of the stories we’ve gotten in are of women who are over the age of 50 — they are past their reproductive years — and they’re still being asked really invasive questions and having roadblocks thrown up,” Dr. Anna Hyde of the Arthritis Foundation told NBC4 in Washington.

Up to 90% of RA patients are prescribed methotrexate at some point. It doesn’t work for everyone and can have side effects, but it’s the only affordable option for many patients, costing about $50 for a month’s supply of generic methotrexate tablets. Other treatments for RA, such as disease modifying biologic drugs, can cost as much as $3,000 a month and are not covered by insurance.  

Women Losing Access to Arthritis Drugs Due to Abortion Bans

It didn’t take long for last month’s Supreme Court decision overturning Roe v. Wade to have a ripple effect on the U.S. healthcare system – including unintended consequences for women of childbearing age who have painful conditions such as lupus, rheumatoid arthritis, migraine and multiple sclerosis (MS).

Methotrexate and other drugs used to treat autoimmune and neurological conditions can also be used to induce abortions because they prevent cells from dividing. Although not commonly used for that purpose, methotrexate is officially listed in Texas as an “abortion-inducing drug” – an abortifacient -- putting practitioners at risk of running afoul of the state’s $10,000 bounty on anyone who helps a woman end a pregnancy after six weeks.

Even in states where abortion is legal, physicians, pharmacists and other healthcare providers have become cautious about prescribing or dispensing methotrexate.

“I received an email from my rheumatologist today that they are stopping all refills of methotrexate because it is considered an abortifacient,” a Virginia woman with lupus posted on Twitter just days after Roe was overturned. “If this is happening in a blue state with no trigger law, think of those in red states where abortion isn’t even legal. And those states that have trigger laws causing extreme and immediate loss of access.”

On the same day Roe was overturned, another poster on Twitter said his wife’s rheumatologist took all his female patients off medications that might cause a miscarriage

“So those patients are going to have to go off the drugs that were helping to control their condition and have worse health outcomes. People are going to die because of this,” he said.

The Lupus Foundation of America and Arthritis Foundation said they were aware of the situation and encouraged affected patients to contact them directly.

In an op/ed published in JAMA Neurology, neurologists at UC San Francisco School of Medicine warn the new abortion limits could have life-changing and life-threatening consequences for women with migraine, MS and epilepsy.

"Even if prescribed for a neurological condition, there are reports from patients across the country stating they are now unable to access methotrexate because it can also be used to induce abortion," wrote lead author Sara LaHue, MD, of the UCSF Department of Neurology. "This could increase risk of morbidity, mortality and irreversible disability accumulation for women with neurologic diseases."

Ironically, some treatments for neurological conditions also increase the likelihood of an unplanned pregnancy because they reduce the effectiveness of hormonal contraceptives. Physicians may become reluctant to prescribe those drugs to women of childbearing age.

Some neurologists may also rule out the use of monoclonal antibodies for women — not because they are used in abortions, but because they may harm a fetus.

"In many settings, women with MS are treated with less effective therapies, because these medications are perceived to be safer in pregnancy," said co-author Riley Bove, MD, of the UCSF Department of Neurology. "Often, neurologists are not familiar with how to time or optimize certain medications, or of their updated safety profile. The reversal of Roe v. Wade may reinforce decisions to stick with the less effective therapies, which may result in irreversible disability for some women with MS."

This week the Health and Human Services Department (HHS) warned retail pharmacies they are at risk of violating federal civil rights law if they deny women access to medications used in abortions. The warning specifically mentions methotrexate when its prescribed to someone with rheumatoid arthritis or some other disabling condition.

“If the pharmacy refuses to fill the individual’s prescription or does not stock methotrexate because of its alternate uses, it may be discriminating on the basis of disability,” HHS said..
