The Link Between Rheumatoid Arthritis and Lymphoma
“A body part from the pain disappeared, and four parts of the body,” Burke said. ”What a beautiful place where I can not immediately go walking or lying down or pick up my second child, who is 10 months old when in I went to see a rheumatologist, I was completely disabled.”
Burke close to the courage and determination of this disease. She is still the envy of the sober, the risk of rheumatoid arthritis and its treatment.
Rheumatoid arthritis is an autoimmune disease. With RA, the immune system attacks the body’s own tissue, leading to chronic inflammation. One autoimmune disease also prone to infections and a host of other medical conditions.
“My immune system is exposed to at this point,” Burke this complain. ”I now know I was in a concentration of risk for many things.”
A disease, Burke is now at a higher risk of lymphoma. This is the beginning of a type of cancer, the body’s lymphatic system and interfere with the body’s ability to make healthy blood cells. Several studies, including a 2008 review of the literature, studies have shown that, RA patients with two to three times the likelihood of developing lymphoma compared with no pull.
RA and lymphoma: the risk measurement
“Pull the link between lymphoma and very famous.” Said John Sweetenham, MD. ”However, lymphoma is rare, it is difficult to find in the end how much increased risk.” Sweetenham is the director of clinical research at the Taussig Cancer Institute Cleveland Clinic in Ohio.
“Most people have rheumatoid arthritis will no longer have this complication,” said Sweetenham, with two states to accept patients.
Some doctors, though, including a Kaman Barton, MD, Ph.D. believes that severe RA could raise your risk significantly higher than in the studies mentioned above, said. Kaman is the executive vice president and chief medical officer of the Leukemia and Lymphoma Society. He pointed out that Burke triathlon training after 2006, Swedish researchers announced that the most severe disease activity in patients with RA from 70-fold increased risk of lymphoma compared to a lower severity. A moderate-severity RA seems people about 8 times more likely develop lymphoma.
There is a rare complication of Felty RA called the syndrome. This is defined as the presence of RA enlargement of the spleen and abnormally low white blood cell count. Felty syndrome appear to at a higher risk of lymphoma.
Individual risk is still small. Lymphoma
Lymphoma is very rare. It is estimated that fewer than 75,000 Americans are diagnosed with the disease last year. Rare diseases and to reduce individual risk.
Rheumatologist Chaim Putterman, MD explains to say: “that may develop into a disease is one in 10 million years. If you have a twofold increased risk, your risk is now in 500 years, this will be a very small increase in your own personal risk. “Putterman is the main division and rheumatism professor of medicine, microbiology, immunology and Medical Center and Albert in part. Albert Einstein College of Medicine in New York.
There are usually two types of lymphoma: Hodgkin’s disease and non-Hodgkin lymphoma (NHL). Non-Hodgkin’s lymphoma is more common. A study, published in January 2009, RA increases the probability of a subtype of breast cancer called diffuse large B-cell non-Hodgkin’s lymphoma lymphoma. This is a fast-growing form of the disease. Also found an increased risk of a rare subtype called t-cell lymphoma.
The actual risk may be related to how long-term treatment of RA patients. In other words, then a person’s immune system is suppressed, there is great risk of lymphoma appears.
RA and risk of lymphoma: disease fault?
What is the exact increased risk of lymphoma? This is the RA disease process or drugs? “That is $ 64,000 question,” Putterman said.
More and more evidence that chronic activation of the immune system caused by the disease process is the increased risk of lymphoma. But doctors are still uncertain.
“It is very difficult to solve this disease process, from drug treatment,” said Eric Engels, MD mile, senior officers from the U.S. National Cancer Institute. ”That is because those diseases are the most active of the strongest drugs.”
“In some people,” Sweetenham explained, “to step up the immune system seems to be more intent, it can no longer be turned off, which eventually turned into cancer.”
“This is not a hard concept that there are specific gene expression of immune system cells,” Kaman said.”If these immune system cells begin to grow out of control, I want to call that’s lymphoma.”
RA lymphoma risk: will drug treatment?
The drug used to treat RA suppress the body’s immune system. Struggle of the occurrence of RA-related inflammation and pain. But they also make your body can not fight infection and disease.
The most common drug treatment, and lymphoma in RA is methotrexate. This is the first of a drug, provided Burke. It is the class of drugs known as disease remission or remission of disease modifying antirheumatic drugs changes. There are some feasibility report, and adopted a series of people, the cancer drug methotrexate to go once they leave. This may indicate that the drug directly contribute to cancer development.

However, many studies, including the Swedish study published in 2006, yet the link between risk and the sun god lymphoma treatment, including methotrexate.
A new class of drugs of concern is to improve the tumor necrosis factor (TNF) antagonists. These are also known as anti-TNF drugs. Such drugs include induced, Enbrel, the annual meeting. They have lifeguards severe RA patients, like Burke. Arthritis Foundation, said the drug treatment adds an important diseases Arsenal.
So far, no clear evidence that anti-TNF drugs cause cancer in adults. May 2009, a study published in anti-TNF drugs are not further increase the risk of heart attack patients with lymphoma pull. However, Putterman said: “The fact is: we do not see it does not mean that there is no contact, which may mean that we do not see it yet.”
However, as treatment becomes stronger, the doctor worry about cancer and other side effects such as infection. Which Sweetenham on: “I think now the introduction of many new drugs treatment in the past five to 10 years, these drugs have some potential to make a slightly higher risk. Unknown how different the feeling of new drugs (such as anti-TNF drugs , intend to. ”
Doctors agree, however, RA treatment benefits far outweigh the potential risks of these drugs. They encourage patients to sit down with their doctors and their families and the balance of the treatment.
This is what Burke has done. After the failure of methotrexate, Burke’s anti-TNF therapy began her rheumatologist, first in the Enbrel, now in the cause. The result is amazing. She pulled completely under control now. ”Drug gave me back my previous life,” she said. ”My medicine is my lifeline.”
The doctor said there is no way to prevent lymphoma. Although there are some reports that oral steroids (such as prednisone) may reduce a person’s risk, doctors abandoned the consensus on that is “very likely” that is feasible.
Burke often see her doctors to prevent any possible complications of the drug. Since her diagnosis, her third child and organized a triathlon for the local Arthritis Foundation fund-raising. She even took part in the swim / run to pass.
“I think a person with chronic diseases, especially there is no cure,” she said, “to be smart how to live with, so they can take advantage of all life has to offer.”
