Women With Lupus at Higher Risk for Hip Fractures?
Study followed nearly 15,000 patients for 6 years
The autoantibodies cause inflammation, pain and damage to the body.
"The systemic inflammation affects bone," Pisetsky said. Patients often are prescribed steroid medicine to relieve the inflammation, but the medicines can also affect bones adversely, he said.
Although the risk to bones in lupus patients is known, the new study teases out details on the type of fracture risk, Pisetsky said.
Treatments, especially the steroids, can affect the bones, said Dr. Joan Merrill, medical director of the Lupus Foundation of America and chairwoman of the clinical pharmacology research program at the Oklahoma Medical Research Foundation. "Steroids are also associated with increased risk for osteonecrosis [death of the bones], which literally can cause the hip joint and other joints to collapse," she said.
For those reasons, experts in recent years have been focusing on using the lowest dose possible of steroids to control symptoms, Pisetsky said.
To help preserve bone health, Pisetsky tells his lupus patients to get enough calcium and vitamin D and to take bone-maintenance drugs, if their doctor decides they are necessary.
Getting regular exercise can help too, he said. With age, lupus patients should try to preserve their balance, which also can reduce the risk of falls.
