Major histocompatibility complex (MHC) class II proteins (HLA-DR, HLA-DP and HLA-DQ) play a fundamental role in the regulation of the immune response. The level of expression of human leukocyte antigen (HLA) class II antigens is regulated by interferon-γ (IFN-γ) and depends on the status of class II trans-activator protein (CIITA), a co-activator of the MHC(More)
BACKGROUND Plasma cystatin (pCyst) is a well-assessed tool for measuring renal function, and it could also play a part in hemodialysis adequacy. METHODS pCyst and other uremic toxins (urea, creatinine, parathyroid hormone, prolactin) were assessed before and after a dialysis session in 18 hemodialysis patients: 7 on bicarbonate hemodialysis (BHD) and 11(More)
Uromodulin is exclusively expressed in the thick ascending limb and is the most abundant protein secreted in urine where it is found in high-molecular-weight polymers. Its biological functions are still elusive, but it is thought to play a protective role against urinary tract infection, calcium oxalate crystal formation, and regulation of water and salt(More)
Immunosuppressive treatment has changed the prognosis of Lupus nephritis over time, but improvement in prognosis is difficult to analyze in different historical periods, and should be better demonstrated in comparison with life expectancy of sex-and age-matched people. Long-term patient and renal survival of 90 patients diagnosed with Lupus nephritis at our(More)
Immunosuppressive treatment has changed the prognosis of renal vasculitis over time, but improvement in prognosis is difficult to analyze in different historical periods, and can be better demonstrated by comparison with life expectancy of sex- and age-matched people. Long-term survival of 101 patients diagnosed with systemic vasculitis at our center from(More)

BACKGROUND The effectiveness of percutaneous revascularisation (PTRA) in the treatment of atherosclerothic renovascular nephropathy (ARN), a leading cause of progressive renal failure, is still a matter of debate. METHODS we reviewed 52 patients submitted to selective stenting from 1991 to 2000 because of ARN, followed for a mean of 22.3 months before and(More)
BACKGROUND To evaluate the metabolic effects of modification of sodium intake in patients with essential hypertension. METHODS Thirteen patients with essential hypertension (10 M, median age 51 yrs, range 21-64) followed in random order a low-sodium and a high-sodium diet (50 mmol Na/day vs 250 mmol/day for two weeks each). At the end of each diet an(More)
