Hypertension and renal failure with right arm pulse weakness in a 65 years old man

Implication for health policy/practice/research/medical education: Antiphospholipid syndrome (APS) is being increasingly recognized as an important cause of kidney injury due to thrombosis at any location within the renal vasculature. The term antiphospholipid syndrome nephropathy (APSN) refers to the kidney damage caused by vascular lesions in the glomeruli, arterioles and/ or interlobular arteries in patients with antiphospholipid antibodies. APSN manifests with hypertension, acute and/or chronic kidney failure, and often a lowgrade proteinuria.
