A Case of Classic Polyarteritis Nodosa Resembling Lupus Nephritis

Classic polyarteritis nodosa (cPAN) is a systemic necrotizing vasculitis of medium-sized muscular arteries. Glomerular involvement is not expected in the course of cPAN. Herein, we describe a case of cPAN with glomerular and multiple arterial involvement. The patient presented with severe abdominal pain and high fever. Urine analysis showed hematuria and 1g/day proteinuria. Kidney biopsy showed fibrinoid necrosis of arterioles and IgG, IgA and C1q positivity raising a suspicion of lupus nephritis. However digital subtraction angiography revealed typical multiple micro-aneurysms in the coronary, mesenteric, splenic and renal arteries establishing the diagnosis of cPAN. Kidney biopsy in cPAN may reveal non-specific immune-deposits and fibrinoid necrosis of arterioles mimicking lupus nephritis and microscopic polyangiitis. c-PAN should be carefully differentiated from these entities

Leptin Parameters are Associated with Inflammation and Both Anthropometric and Serum Markers of Protein-Energy Wasting in Hemodialysis Patients

OBJECTIVE: Protein-energy wasting (PEW) and inflammation are common and related to increased cardiovascular mortality in hemodialysis (HD) patients. Herein, we aimed to investigate the relationships between adipocytokines, inflammation and serum and anthropometric markers of PEW syndrome in HD patients
