| Design | Controlled Randomised
| Purpose of study | ACE inhibitors and angiotensin II receptor antagonists are drugs capable of reducing proteinuria. These are normally used, with success, in patients with proteinuria greater than 1 gram a day or in patients with arterial hypertension. We don.t know if these drugs, when given during the early (benign) phase of the disease, are capable of reducing the risk of disease progression to a more severe form. The aim of this study is to evaluate this possibility.
The role of biochemical and genetic markers in predicting the nephropathy.s progression and the response to therapy with these drugs will also be evaluated.
| | | | | Summary of study design, objectives, and ongoing research findings | The study foresees randomization of patients into three groups: the first will receive a small daily dose of ramipril (an ACE inhibitor), the second a small daily dose of irbesartan (an angiotensin II receptor antagonist), while the third will only undergo periodic controls to check the glomerulonephritis. progression (this is done routinely as part of daily clinical practice).
All patients will be followed for at least 5 years.
During the study, blood and urine samples will be collected to evaluated the renal disease.s progression from the start and the glomerulonephritis. progression over time in order to verify whether genetic or biochemical factors capable of allowing us to predict the glomerulonephritis. progression.
If the disease should become more severe (arterial hypertension, proteinuria greater than 1 gram/day), the patient will be treated in the most appropriate and effective way to block the disease.s progression, as deemed appropriate by the physician.
