Promising leadsWhat is the future of arthritis research? Research in arthritis holds great promise for discoveries that will help many people.
Scientists may be able to correct malfunctions in the immune system.
They may be able to immunize people against bacteria or viruses that
trigger some forms of arthritis. And they may be able to prevent types
of arthritis from ever happening by identifying and eliminating those
factors that cause them. One of the biggest areas of future research
will concern genes and gene replacement. Some forms of arthritis
probably result from genes that have the wrong set of instructions. For
example, several types of gout
result from such genes. If scientists can find out exactly how genes
influence the development of a particular type of arthritis, they may
eventually be able to replace a gene that increases your risk for
disease with one that carries no increased risk. Sometimes, scientists
find things that cause or increase our risk for disease by studying
differences in patterns of disease in large groups of people. This area
of study is called epidemiology. For example, almost everyone over 65
shows signs of osteoarthritis
on X-ray. But, only one-third of those with X-ray evidence of disease
ever feel symptoms. Why? Studies of differences in disease patterns may
offer us some clues to the answers. Women get some arthritis-related
diseases--such as rheumatoid arthritis, lupus, and osteoporosis--more often than men. Scientists are now studying the effects of both male and female hormones in some types of arthritis.
For instance, women develop osteoporosis after menopause, when a
drop occurs in levels of the female hormone estrogen. Symptoms of
rheumatoid arthritis and lupus may temporarily disappear while a woman
is pregnant,
when female hormone levels are high, only to come back after the baby
is born. Yet, an eight year study of nurses failed to show a reduced
risk for rheumatoid arthritis in women who used birth control pills
containing estrogen. Researchers are trying to discover how hormones
work to protect or expose people to some arthritis related diseases.
