Vasculopathy and vasculitis in systemic lupus erythematosus Cieslik P; Hrycek A; Klucinski PPol Arch Med Wewn 2008[Jan]; 118 (1-2): 57-63Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease, where vascular lesions are one of the typical symptoms. The pathological process often involves skin vessels, renal glomeruli, the cardiovascular system, brain, lung alveoli, and gastrointestinal tract vessels. This review presents possible adverse mechanisms underlying the cause and effect relationship of various factors causing vascular lesions in SLE patients. The generally accepted hypothesis links vascular damage in SLE with the deposition of immune complexes in the vascular endothelium. The anti-endothelial cell antibodies (AECA), antiphospholipid antibodies and anti-double stranded DNA antibodies present in SLE, that directly or indirectly affect endothelial cells, causing inflammatory damage to the vessel wall, and their role, have been discussed. It has been stressed that although the suggested role of AECA in vasculitis pathogenesis has not been fully established, evidence, however, has demonstrated that AECA is a factor causing endothelial damage in SLE patients. On the other hand, issues concerning cellular adhesion molecules which enable leukocyte adhesion and rolling along the endothelial cell surface, and their extravascular migration, focus on the role they may be playing in SLE patients with vasculitis. A potential role of soluble forms of adhesion molecules, pentraxin 3, medications, infections in the pathogenesis of this disease has also been shown. Special attention has been given to the role of type 3 hepatitis virus in vascular damage in SLE.|Antibodies, Antinuclear[MESH]|Antibodies, Antiphospholipid[MESH]|Autoantibodies/immunology[MESH]|Cell Adhesion Molecules[MESH]|Endothelium, Vascular/*immunology[MESH]|Humans[MESH]|Lupus Erythematosus, Systemic/*immunology/*physiopathology[MESH]|Vasculitis/*immunology/*physiopathology[MESH] |
