Combination regimen of leflunomide plus methylprednisolone in a female patient with reactive arthritis and concomitant IgA nephropathy

Spondyloarthropathies （SpAs） include five categories： ankyloslng spondyllns （AS）, reactive arthritis （ReA）,psoriatic arthritis （PsA）, enteropathic arthritis （EA） and undifferentiated spondyloarthropathy （USpA）.2 ReA is an aseptic arthritis occurring after extra-articular infections, particularly genitourinary （GU） or gastrointestinal （GI） tracts. When arthritis is accompanied by conjunctivitis and urethritis, the diagnosis of Reiter syndrome will be suitable for this clinical triad; however, the term ＂ReA＂ has been proposed to substitute for Reiter syndrome.
