Press Release RHEUMATOID ARTHRITIS (RA) MYTHS 20 million people live with RA1 everyday Irreversible joint damage occurs in 70% of all cases within 2 years of a RA2 diagnosis. A panel of Roche experts determined the 10 most frequent Rheumatoid Arthritis (RA) myths. Myth #1: Rheumatoid Arthritis only affects senior citizens Reality: Rheumatoid Arthritis may occur in any ethnic group at any age. Myth #2: RA occurs mostly in people that are 60 or older. Reality: RA mostly affects people between 30 – 50 years-olds. For this reason it is important to perform a diagnostic exam if a person experiences major symptoms (morning stiffness, inflammation and pain). Myth #3: RA affects both men and women equally. Reality: Women are at a higher risk of developing RA. Women have a higher incidence of the disease. Myth #4: Smoking does not affect joints. Reality: Smoking is a risk factor for RA. Myth #5: RA is not hereditary Reality: A family history of rheumatoid arthritis is a risk factor. 1 O’Dell JR . N Engl J Med 2004 2 © 2002-2009 F. Hoffmann-La Roche Ltd Myth #6: RA is reversible. Reality: Joint damage is irreversible. Surgery can reestablish deformed joints. But damage to adjacent tissue is irreparable and prevents a person from fully recovering mobility. Myth #7: Damage occurs only to hands Reality: AR may occur on hands, elbow, knees, feet, shoulders and wrists. Once swelling is chronic, joints become deformed and destroyed, leading to , weakness or atrophy of the adjacent muscles. Myth #8: AR is a joint disease Reality: RA is a systemic disease. It not only affects joints, but may also damage other organs such as the liver, kidney, eyes, heart and adjacent peripheral blood vessels. Myth #9: RA advances slowly Reality: Rheumatoid Arthritis may be transitory or chronic. It may experience periods of inactivity or alternative relapses. Myth #10: RA is an isolated symptom. Reality: In addition to joint pain, symptoms include anemia, osteoporosis and cardiovascular disease. Currently, 20 million people live with rheumatoid arthritis daily all over the world. Rheumatoid Arthritis is an autoimmune disease in which the body attacks its own tissue. Instead of fighting microorganisms or antigens that are potentially dangerous, the immune system identifies parts of its own body as «foreign» and attacks it. As a result, inflammation, congestion and pain occur in joints (hand, foot, knee, elbows, shoulders, wrists and ankles). In more advanced states, inflammation becomes chronic and joints become deformed and are destroyed. Adjacent muscles atrophy, weaken and show subcutaneous nodules in certain cases. 70% of patients experience irreversible joint damage within 2 years after being diagnosed with RA. For this reason, early detection of the disease is key to overcoming it. ACTEMRA® (tocilizumab): Efficient Treatment There is effective treatment for stopping the growth or advancement and controlling the disease. Recent studies (OPTION, TOWARD, RADIATE, STREAM), practiced on all types of rheumatoid arthritis patients throughout the world, demonstrated that ACTEMRA was effective in improving joint pain, controlling fatigue and increasing disease remission rates. The results could be seen in patients as rapidly as 2 weeks after use. It was demonstrated that ACTEMRA had a rapid, potent and overall effect on patients. The drug inhibits progression of joint damage with consistent remission rates and significant improvement seen in patients the longer it was used. ACTEMRA acts by inhibiting the IL-6 (Interleukin) receptor, a substance that is responsible for most of the acute and chronic inflammation associated with chronic arthritis. As a result, the evolution of the disease is controlled as well as associated symptoms. Before Actemra, no drugs had performed that function and achieved the results obtained up until now. Specialists recommend making changes to adapt the patient´s lifestyle to his or her actual RA condition in order to facilitate their daily, help them feel independent and integrated with society.
