NSAID use and long-term decline of renal function
Background
• NSAIDs may cause different Adverse Events: Cardiovascular system
( HTA, LVF, MI), Platelet function (Prostacyclin/Thromboxan
Ratio), Gastrointestinal system (GI bleedings)
• Non-steroidal anti-inflammatory drugs (NSAIDs) may cause kidney
damage due to
Vasoconstriction
tubular necrosis
acute interstitial nephritis
• RA patients commonly require more extensive NSAID use than others
• They are at increased risk of impaired renal function and renal failure

NSAID use and long-term decline of renal function
Objective
Is longterm decline of glomerular filtration (eGFR estimates)
in RA patients influenced by NSAID use ?

4. SCQM – The Swiss reference platform for research and quality management in rheumatology
NSAID use and long-term decline of renal function
Methods
• 4101 patients, mean observation time 3.2 years
• Primary outcome:
eGFR estimate according to the Cockroft-Gault formula, eGFRCG
• Secondary outcomes
Modification of Diet in Renal Disease (eGFRMDRD)
Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation
(eGFRCKD)
Absolute serum creatinine concentrations
• Statistical methods
mixed models for longitudinal data

In patients with preserved
baseline (eGFRCG >30
ml/min):
• eGFRCG evolved without
significant differences over
time between ‘NSAID
users’ and ‘NSAID
naive’pts (p=0.63)
• Mean change in eGFRCG
− NSAID users: - 0.87
[CI: -1.15 to -0.59] ml/min/yr
− NSAID naïve: -0.67
[CI: -1.26 to -0.09] ml/min/yr

Effect modification by
baseline renal function:
NSAIDs were an independent
predictor for rapid renal
function decline only in
patients with baseline renal
failure (eGFRCG <30 ml/min,
CKD stages 4 or 5):
• Mean change in eGFRCG
− NSAID users CKD 1 or 2:
-1.27±0.17 ml/min/yr
− NSAID users CKD 4 or 5:
-9.98±2.12 ml/min/yr

Conclusion
NSAIDs had no negative impact on renal function estimates,
except in patients with advanced renal impairment.
