Biologic Therapies for RA Reduce Kidney Risks

Restricted access

In patients with rheumatoid arthritis, treatment with biologic agents is associated with a lower risk of declining renal function and chronic kidney disease (CKD), reports a study in Kidney International.

Using a Department of Veterans Affairs database, the researchers identified 20,757 veterans diagnosed with RA between 2004 and 2006, with follow-up to 2013. All included patients had initially normal kidney function: estimated glomerular filtration rate (eGFR) 60 mL/min/1.73 m2 or higher. Treatment with biologic agents was examined for association with incident CKD, defined as eGFR less than 60 mL/min/1.73 m2, with at least a
