Abstract
Objective:
Statins have anti-inflammatory/immunomodulatory effects that may be
useful to prevent rheumatoid arthritis (RA) but previous observational
studies about the risk of RA with statin use provided conflicting
results. The aim of this study was to determine whether high-intensity
statin treatment is associated with a lower risk of rheumatoid
arthritis.
Methods: Using data from
the UK Clinical Practice Research Datalink, we performed a nested
case-control analysis in a population-based cohort of new statin users
between 1997 and 2009, followed until a first diagnosis of RA, death,
end of registration or end of 2009. For each case of RA, 10 age, sex and
calendar year-matched controls were randomly selected from risk sets.
We estimated the hazard ratio (HR) of incident RA in the highest
quintile of duration-weighted average statin intensity compared with the
lowest, using conditional logistic regression. Models were adjusted for
smoking status, total cholesterol levels, obesity, history of
cardiovascular disease, coexistent autoimmune diseases, hypothyroidism
and persistence with treatment.
Results:
The cohort included 528,654 new users of statins, with 1,357 new RA
cases during a mean 3.3 years of follow-up, for an incidence rate of 7.9
per 10,000 person-years. Cases were more likely to be smokers, have
other autoimmune diseases and lower total cholesterol levels at
baseline. The incidence of RA was lower in the highest statin intensity
quintile (adjusted HR 0.77; 95% CI: 0.63-0.95) in comparison to the
lowest quintile.
Conclusions: In
this large population-based study, high-intensity statin treatment was
associated with a reduced risk of RA in comparison with low-intensity
statins. This article is protected by copyright. All rights reserved.
