Autoantibodies against oxidized low-density lipoprotein and lipid profile in patients with chronic periaortitis: case–control study

“…Although the presence of these antibodies may be an epiphenomenon of little pathogenetic significance, the postulated pathogenesis of chronic periaortitis as being the result of an autoallergic reaction to OxLDL has since been adopted by many investigators (6)(7)(8). The described association with autoimmune disorders and the often observed beneficial response to immunosupressive treatment would further fit the proposed hypothesis (9,10).…”

Unilateral Perirenal Fibrosis

“…8,9 Some proposed that it is a vasculitic disease because a prominent perivascular inflammation occurs in the early course of the disease 10 ; others postulated that RPF is a manifestation of a systemic collagen disease. Some authors equated RPF with immunemediated connective tissue disorder, with fibrosis developing in response to leakage of ceroid from atheroma into the periaortic tissue or with perianeurysmal fibrosis.…”

U-shaped Bilateral Ileal Ureter Substitution for Failed Conservative Management of Retroperitoneal Fibrosis: A Case Report

“…The cause is often unknown, but medications, malignancy, and vascular aneurysms are occasionally associated with RPF [3]. The fibrotic tissue associated with abdominal aortic aneurysms (AAA) can spread to both common iliac arteries and encase both ureters [4], leading to bilateral ureteral obstruction and hydronephrosis.…”
