Abstract

Background: About 10% of rheumatoid arthritis patients are seronegative, (rheumatoid factor is negative). These patients may be resistant to conventional anti-rheumatic drugs (DMARDs). Pamidronate is one of the drugs of the bisphosphonate group, which can control bone resorption by effect on osteoclasts. Anti-inflammatory effect of this drug can be exerting by increase monocytes apoptosis, which followed decrease serum level of Interlukin-1 (an inflammatory cytokine). As a result pamidronate can control disease activity. Case Report: In this article, I report two cases of seronegative rheumatoid arthritis that dramatically responds to pamidronate. © 2011, Isfahan University of Medical Sciences(IUMS).
