Use of exogenous sex hormones tied to more frequent remission in women with rheumatoid arthritis

Australia: The use of oral contraceptives or hormone replacement therapy (HRT) is linked to a greater chance of remission in female rheumatoid arthritis (RA) patients, specifically those who were perimenopausal and early postmenopausal, according to a large study.
Researchers, led by the University of South Australia, also found that perimenopausal women were less likely to achieve remission than premenopausal rheumatoid arthritis patients.
The study linked remission, reproductive status, and sex hormone use, after assessing data from 4474 female rheumatoid arthritis (RA) patients treated with the anti-inflammatory drug Tocilizumab and other immuno-suppressive medications.
The study revealed the following:
• Pre-menopausal women (those still experiencing a regular menstrual cycle) reported fewer RA symptoms than peri-menopausal (irregular or infrequent periods) or post-menopausal women with RA.
• RA patients using HRT or oral contraceptives in combination with the drugs prescribed for rheumatoid arthritis had a much greater likelihood of remission.
• Post-menopausal women, comprising 63 per cent of the participants, of whom only eight per cent were using HRT, were less likely to achieve RA remission than pre-menopausal women.
The findings suggest that female sex hormones could play a major role in improving the outcome of women taking drugs prescribed for rheumatoid arthritis.
Remission rates were higher in some groups of women who were taking HRT or oral contraceptives at the same time they were taking medicines for RA, and in fact, RA remission was twice as high in peri-menopausal women.
Lead researcher UniSA Associate Professor Michael Wiese says it’s premature to say that HRT and oral contraceptives protect against rheumatoid arthritis, but the study has revealed a potential connection.
“We looked at whether women who used oral contraceptives or HRT had different outcomes when treated with drugs for rheumatoid arthritis. We found that women entering menopause who were not taking HRT or contraceptives were less likely to achieve remission compared with RA women still experiencing a regular menstrual cycle,” Assoc Prof Wiese says.
“The decision to use HRT is complex,” Assoc Prof Wiese says. “It does improve menopause symptoms, but it can modify the risk of some cancers and cardiovascular disease. This study suggests it could also benefit women with rheumatoid arthritis. Still, using it requires an in-depth discussion with a general practitioner because each woman has different risk factors.”
Rheumatoid arthritis is an autoimmune inflammatory condition four times more prevalent in women under 50 years than men in the same age bracket and is twice as common in women over 60 years.
Compared with males, rheumatoid arthritis is more aggressive in women, and the prognosis worsens.
“The peak age of onset of rheumatoid arthritis among females is 45-55 years, corresponding with a drop in oestrogen when women typically enter a peri-menopausal period, where their periods become irregular.
“Furthermore, at the onset of menopause, there is an increase in pro-inflammatory proteins.”
Early menopause or menopause that occurs in women under 45 years increases the risk of developing rheumatoid arthritis and the incidence also sharply spikes in post-menopausal women.
Conversely, younger women with rheumatoid arthritis who fall pregnant experience a 50% decline in inflammatory activity.
