Immunoglobulin A (IgA) nephropathy is the most common type of primary glomerulonephritis in the world. The treatment of IgA nephropathy with normal renal function and minimal proteinuria is unknown. Since angiotensin-converting enzyme (ACE) inhibitors reduce proteinuria and retard the rate of decline of renal function in chronic proteinuric nephropathies, including IgA nephropathy. The investigators conduct a randomized control study to evaluate the efficacy of ACE inhibitor in the treatment of early IgA nephropathy. Sixty patients with biopsy-proven IgA nephropathy and minimal proteinuria are recruited. They will be randomized to ramipril for 5 years or no treatment. Blood pressure, proteinuria and renal function will be monitored. This study will explore the effects of ACE inhibitor in the treatment of early IgA nephropathy, which is a major cause of dialysis-dependent renal failure.
This study is to evaluate efficacy and safety of tacrolimus in the patients with non-nephrotic albuminuric, normotensive IgA nephropathy after 16 week treatment with tacrolimus (Prograf) or placebo.
The purpose of this study is to assess whether a tailored diet, eliminating antigens to which IgA nephropathy patients have demonstrated sensitivity, will have an effect on proteinuria, renal function and other immunological variables.
The purpose of this study is to evaluate the effect of aliskiren, a novel direct rennin inhibitor, on renal function and progress of renal disease in hypertensive patients with IgA nephropathy.
Primary Hypothesis: Aldosterone breakthrough will occur at a far lower frequency during renin inhibition (0-10% over 9 months), alone or in combination with an ARB, compared to conventional ARB therapy (35-45% over 9 months). The investigators hypothesize that aldosterone breakthrough occurs due to accumulation of active precursor substances, most notably angiotensin II, produced in response to conventional RAAS blockade with ACEinhibitors and ARBs. The investigators believe that direct renin inhibition (DRI) should minimize this accumulation and therefore significantly lower or possibly eliminate the breakthrough effect. Interruption of the renin-angiotensin-aldosterone system (RAAS) with angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin receptor blockers (ARBs), alone and in combination, has become a leading therapy to slow the progression of chronic heart and kidney disease. Both types of drugs inhibit the formation of aldosterone, a hormone, which has been shown to have harmful effects on patients with chronic heart and kidney disorders. This treatment is effective but not perfect since, even after an initial improvement, many patients become worse over the long term. This may be due to an unexpected increase in aldosterone, a phenomenon called "aldosterone breakthrough." The purpose of this study is to find out whether the use of a direct renin inhibitor (DRI) alone, or in combination with an angiotensin receptor blocker (ARB), will lessen the occurrence of aldosterone breakthrough since direct renin inhibitors inhibit the formation of aldosterone at a very early step. This study will compare the effectiveness of adding Diovan (valsartan) or Tekturna (aliskiren) or a combination of Diovan and Tekturna to the usual antihypertensive treatment. The investigators will follow blood pressure, aldosterone levels, and urinary protein levels over 9 months to evaluate which of these therapies is most effective for treating hypertension in patients with proteinuric kidney disease.
This study evaluates prospectively the effects of an anti-angiotensin II regimen on renal outcome in patients with mesangioproliferative glomerulonephritis followed-up for 10 years.
The primary objective of this study is to investigate the ability of Velcade® (bortezomib) to induce complete or partial remission in patients with severe IgA nephropathy. The secondary objectives are to assess clinical outcomes relating to safety and efficacy, such as infection, malignancy, preservation of renal function, partial responders, relapse rate, and to study mechanistic assays to predict remission.
Study objective: To investigate the potential anti-proteinuric efficacy of aliskiren, a novel direct renin inhibitor (DRI), in addition to angiotensin receptor blocker (ARB) in immunoglobulin A nephropathy (IgAN) patients at risk of developing progressive renal failure.
The purpose of this study is to: 1. To evaluate the latest effects of TW for IgA nephropathy (IgAN) with asymptomatic abnormal urinalysis. 2. To evaluate the safety and tolerability of TW.
