Familial Takayasu arteritis in a mother and daughter. A report of two cases

Takayasu arteritis (TA) is a chronic granulomatous panarteritis, predominantly affecting the aorta and its main branches. Infections, genetic factors as suggested by familial clustering, and autoimmunity may play a role in its pathogenesis. In this report, we describe familial TA in a mother and daughter with diverse clinical manifestations. In addition to being a familial form of vasculitis, both of our cases demonstrated amyloidosis, chronic renal disease thought to be due to ischemic nephropathy, and hypertensive nephrosclerosis.
