ETIOLOGY

� Still unknown

� Genetic factor, UTRI, food,immunization,

medicine

� After treatment by antirheumatic, MTX, � After treatment by antirheumatic, MTX,

anti-TNF

� Increase IgA serum concentration,

immune compleks, and IgA deposit in

vessel walls / mesangial renal �

important role

PATOFISIOLOGY

� Renal / skin biopsi : immune deposit compleks

(contains IgA)

� Complement activation (alternative pathway)

� Mediator inflamation activation (vascular

prostaglandin) � small vascular inflamation in prostaglandin) � small vascular inflamation in

the skin, renal, joint and abdominal � skin

purpura, nephritis, arthritis and GIT bleeding

� Histologis : vasculitis leukocitoclastic
