Nov. 9, 2007 (Boston) -- A new inflammation-fighting drug may spell relief
for people with severe gout who are unable to take other drugs for gout treatment because of underlying health
Given by injection just underneath the skin, rilonacept (IL-1 Trap) blocks interleukin-1, a
protein involved in inflammation. A new study of 10 people with severe gout
shows that it substantially decreases both disease activity and pain.
The findings were presented at the American College of Rheumatology's Annual
Scientific Meeting in Boston.
"Lots of gout patients can't take standard anti-inflammatory drugs such
as nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine, or systemic steroids because they
may have kidney problems, heart problems, or diabetes," explains researcher Robert Terkeltaub,
Terkeltaub is section chief of rheumatology-allergy at the VA Medical Center
in San Diego and a professor of medicine at the University of California, San
Diego. "Now we can help break the inflammatory loop in these patients,"
"IL-1 is a lynch pin of gout inflammation, and if we can block the lynch
pin, we can stop the inflammatory cascade," Terkeltaub tells WebMD.
Gout is a condition characterized by "flares" of intense pain,
redness, inflammation, and warmth in the affected joint. It is caused by
an accumulation of uric acid crystals in joints, which can also build up in
other areas of the body. As the disease progresses, these flares may become
more frequent and patients may develop joint deformity and large deposits of
crystals, which can become visible under the skin (called tophi). Patients with
gout can also develop kidney stones and kidney damage.
Uric acid is found naturally in the body. In gout, there is generally a
problem with either too much production of uric acid or problems in getting rid
of the uric acid, or both. During an attack, gout is typically treated with
drugs that cool inflammation. In addition, uric-acid-lowering drugs are
Some uric-acid-lowering drugs actually cause flares, and it is possible the
new drug may be used along with drugs to lower uric acid to help prevent such
