Background Patients with rheumatoid arthritis (RA) are at increased risk of renal dysfunction.

Objectives To assess the prevalence and associations of renal dysfunction in patients with RA.

Methods COMEDRA is a French nation-wide cross-sectional multicentric study on comorbidities in RA patients. Renal function was assessed by estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease (MDRD) equation in patients from the COMEDRA study. Demographics and RA characteristics, risk factors for renal dysfunction (cardiovascular risks, medications) were collected in all participants.

Results Of the 970 recruited patients, 931 were analyzed (female gender: 79.6%, age: 57.8 years, disease duration: 11.1 years, DAS28-erythrocyte sedimentation rate: 3.1). 8.8% of patients had eGFR<60 ml/min/1.73m2. 9.9% of the patients had proteinuria (as defined by positive dipstick testing). In univariate analysis, age (p<0.001), presence of hypertension (p<0.001), systolic blood pressure (p=0.03), and Framingham Risk score (p<0.001) were associated with eGFR<60 ml/min/1.73m2. Renal dysfunction was not associated with gender (p=0.35), disease duration (p=0.91), disease activity (for DAS28-erythrocyte sedimentation rate: p=0.14, for SDAI: p=0.41, for CDAI: p=0.77) or RA medications. Two models of multivariate analysis were constructed: Model A, without the Framingham risk score revealing that age (OR: 1.05; IC95% [1.03-1.09]) and hypertension (OR: 2.5, IC95% [1.5-4.3]); were predictive of eGFR <60 ml/min/1.73m2 Model B revealing that the Framingham risk score was predictive of eGFR <60 ml/min/1.73m2 (OR 1.06, IC95% [1.03-1.09]).

Conclusions Renal impairment is quite common and associated with cardiovascular risk factors such as age, hypertension and Framingham risk score but not with disease activity.
