Renal damage in rheumatoid arthritis

: Renal damage is not uncommon in rheumatoid arthritis, but the causative role of the disease per se is not well defined yet. In this paper the updated literature data are reported and our own experience as well. In particular, we describe renal syndromes associated with non-steroidal antiinflammatory drugs, remission-inducing agents (gold and penicillamine) and cytotoxic drugs, secondary amyloidosis, systemic rheumatoid vasculitis, glomerular and tubulo-interstitial nephritis not related to drug therapy.
