Here’s why the disease progresses, what to expect, and how to stop it.
Rheumatoid arthritis (RA) is a chronic condition for which there is no cure. But even though the disease is progressive, newer disease-modifying drugs may actually be able to slow or even halt it getting worse. “We have many effective treatments for RA that help control the symptoms of joint pain and stiffness, but also prevent progression of the disease and the development of permanent damage,” says Lindsay Lally, MD, a rheumatologist at Hospital for Special Surgery in New York City.
Early treatment for RA is key, because whatever joint damage has already occurred can’t be reversed. Find out how to recognize the symptoms at each stage of RA, and what can be done to treat it.
Stage 1: Early RA
In the autoimmune process of RA, the body mistakenly attacks its own joint tissue. “In early RA, the patient may not have many symptoms except for some stiffness in the early hours of the morning, primarily small joints — hands, the foot, sometimes the knees,” says Rajat Bhatt, MD, a rheumatologist at Allergy and Rheumatology Specialists of Houston. The stiffness gets better with movement, which differentiates it from osteoarthritis, the “wear-and-tear” degenerative kind.
Ideally at this point you’d see a specialist called a rheumatologist. The only problem is that symptoms may be vague or come and go, making the diagnosis of RA difficult. “It can be challenging to diagnose RA in the very early phases,” says Dr. Lally. “Often patients with early RA will have joint pain without the characteristic swelling of RA. Moreover, in early inflammatory arthritis there may be only one affected joint that has evidence of swelling as compared to the classic presentation of RA, which tends to involve small joints of the hands and feet in a symmetric fashion.”
Dr. Lally says that antibodies in the blood, though, can be present for years before symptoms develop. In addition, “while X-rays at this time are usually normal, more sensitive imaging like ultrasound may show fluid or inflammation in an affected joint,” Dr. Lally says. Still, definitive testing for RA is difficult early on because although these inflammation markers may show up in blood tests, they might not, Dr. Bhatt says. Ultrasound also may or may not show anything unusual.
Stage 2: Antibodies Develop and Swelling Worsens
In many cases, RA progresses to the second stage without being diagnosed. “In the second stage the body makes the antibodies [shown in blood work] and the joints start swelling up,” Dr. Bhatt says. “It can affect other organ systems and cause inflammation there: the lungs, the eyes, a skin rash, and it can even affect the heart.” Lumps on the elbows called rheumatoid nodules may also develop. (Keep in mind, though, that some people have what’s known as seronegative RA, in which blood tests don’t reveal antibodies like rheumatoid factor or anti-citrullinated protein antibodies, or anti-CCP.)
When it comes to imaging results, the “second stage is more confirmative for the diagnosis,” Dr. Bhatt says. “It has kind of a moth-eaten, chipped off appearance on the X-rays. Ultrasound can also be done, and the most sensitive is an MRI, which would pick up if there are any problems even if the X-ray is normal.”
Stage 3: Symptoms Are Visible
In this latter, more severe stage, blood tests and imaging are less relevant for diagnosis because you can actually see the effects of the disease. “The joints start becoming bent and deformed, the fingers become crooked,” Dr. Bhatt says. These misshapen joints can press on the nerves and can cause nerve pain as well, he says. “In the older days we used to see more deformed joints when we did not have much treatment, but now we are seeing less and less,” Dr. Bhatt says.
Stage 4: Joints Become Fused
If not treated, the disease will progress to the last stage, in which “there’s no joint remaining at all and the joint is essentially fused,” Dr. Bhatt says. Luckily, with treatment, people with RA do not reach this stage.
How to Know if Your RA Is Progressing
“You will know — your joints will tell you,” Dr. Bhatt says. “The pain will get worse and you could have more swelling.” Dr. Lally says that although periods of pain may resolve on their own in early RA, “these episodes tend to become more frequent and longer in duration until the classic features of RA persist.” In addition, Dr. Bhatt says to pay attention to non-joint symptoms like increased shortness of breath or red, painful eyes, which could be signs the RA is affecting other systems in the body. Let your doctor know if your RA symptoms are changing at all.
What Makes RA Get Worse?
Different factors affect the pace and progression of individual patients’ RA. Some things you can’t control, like whether you have a family history of the disease. In addition, although women are more likely to get RA, when men get rheumatoid arthritis, their prognosis is generally worse, Dr. Bhatt says.
But there are factors you can control and change. “We know smoking makes RA more aggressive, so smoking cessation is key,” Dr. Lally says. Also, people with “heavy manual occupations might stress the joints further and might have quicker progression,” Dr. Bhatt says. If your workplace can make accommodations for your disease, that will help. Read more about how to make working with arthritis easier.
Exercise and maintaining a healthy weight can also help reduce stress on the joints, Dr. Bhatt says. But talk to your doctor before starting a workout regimen. “A physical therapist can advise patients on the right type of exercise,” he says. “If patients do exercises wrong it could stress the joints even further.” In addition, getting enough sleep, starting an anti-inflammatory diet, eating less red meat, and possibly using herbal remedies like turmeric may help control RA, Dr. Bhatt says. Here are more healthy habits to adopt if you have RA.
How Your RA Treatment Plan Prevents Disease Progression
Perhaps the biggest factor that affects how RA progresses is if you’re in treatment with a specialist who can put you on medications to slow the disease. “Being on a DMARD or biologic therapy for RA is the best way to prevent progression,” Dr. Lally says.
Disease-modifying anti-rheumatic drugs (DMARDs) are usually the first line in medication. “Methotrexate [a DMARD] is the anchor drug for rheumatoid arthritis,” Dr. Bhatt says. “Some patients are scared because methotrexate is also used for cancer chemotherapy so they don’t want to take a ‘chemo pill,’ but those we use for RA are a very small dose with lesser chance of side effects.” Your doctor will reassess in a month or so and see if it’s necessary to add in other drugs.
“If after three to six months they have still not responded then we progress to medications called biologics,” Dr. Bhatt says. These genetically engineered drugs target the inflammation process specifically, and are usually self-injected or infused via IV in your doctor’s office or a medical center. “There are sub-classes and different types,” Dr. Bhatt says. Your doctor will try various medications to see which you respond best to.
Understanding a “Treat-to-Target” Approach
Rheumatologists follow a “treat-to-target” strategy when it comes to how to manage the disease and prevent progression. This means treating the disease aggressively until a treatment target, such as low disease activity, is reached.
“The concept of treat to target is a partnership between patient and physician to get RA into a state of low disease activity or remission,” Dr. Lally says. “This approach requires routine examinations usually every three months. If there is evidence that the RA is not adequately controlled, the medication regimen is changed in an attempt to get to the target of remission.”
