Living With Pain: A Scare for Arthritis Patients
By Josh Fischman
Posted 10/11/06
Headlines like "Death risk linked to steroid use for arthritis" are not comforting, since most of the 2 million rheumatoid arthritis patients in this country have been on steroid pills such as prednisone at one point or another. Yet that's the headline Reuters used last week to announce a new study hinting that RA patients who used prednisone had a higher death rate than those who didn't; the story was also picked up by Scientific American's website and a TV station as far away as New Zealand.
Yet news headlines like this are way overblown. "We've all known that corticosteroids like prednisone are two-edged swords," says Roland Moskowitz, a rheumatologist at Case Western Reserve University School of Medicine and a leading arthritis researcher. "They do have side effects. But used carefully they are safe, and they are really valuable medications." The drugs damp down inflammation, a hallmark RA symptom.

The study, conducted by researchers in Finland and published last month in the Journal of Rheumatology, focused on 600 RA patients, 65 percent of whom had been treated with corticosteroids. Compared with those who didn't get the drugs, corticosteroid patients' risk of death was 14 percent higher after one year and 69 percent higher after 10 years. Causes of death were mostly related to infections.
Scary numbers, but steroids may not be the only reason behind them. In their paper, the Finnish researchers caution that other factors could account for the deaths they observed. "It's the sickest patients who get more corticosteroids, and since they were sicker to start with, you'd expect more deaths," says Moskowitz. "Plus they were being treated with many other drugs, so it's impossible to single out the steroids as responsible for the deaths. It could have been other drugs, and it could have been their greater degree of illness."
Other studies, in fact, have shown that steroids like prednisone are safe in low doses–less than 7.5 milligrams per day for women and under 10 milligrams for men. "Steroids are very important as 'bridge' therapies" to help patients while they wait for other drugs to kick in, Moskowitz says. "If a patient is seriously flaring with inflammation, you put them on low-dose prednisone for three months until other drugs, such as methotrexate, build up in their bodies enough to have an effect."
Steroids can cause side effects like hypertension and osteoporosis, so they are best used for short periods. And people on them need to be carefully watched. But fear of death as a major side effect is premature. |
