Arthritis Research

Scientists are looking at new ways to treat rheumatoid arthritis. They are experimenting with new drugs and "biologic agents" that selectively block certain immune system activities associated with inflammation. Newly developed drugs include etanercept (Enbrel) and infliximab (Remicade).

Some genetic and behavioral studies are focusing on factors that may lead to osteoarthritis. Researchers recently found that daughters of women who have knee osteoarthritis have a significant increase in cartilage breakdown, making them more susceptible to disease. This finding has important implications for identifying people who are susceptible to osteoarthritis. Other studies of risk factors for osteoarthritis have identified excessive weight and lack of exercise as contributing factors to knee and hip disability.
