Brief Summary:
The natural course of extracapillary glomerulonephritis is severe leading to End-Stage Renal Disease (ESRD) or death in most cases. Despite immunosuppressive treatment, long-term renal outcome remains poor since active crescents usually progress to fibrotic scars with glomerular occlusion and disruption.In experimental models Angiotensin Converting Enzyme (ACE)-inhibitor therapy targeting the over-expression of angiotensin type 1 (AT1) receptors, that are responsible for dysregulated proliferation of parietal cell progenitors, blocks the formation of crescents and their fibrotic evolution. Should these drugs have similar effects in humans, ACE-inhibitor therapy on top of standard immunosuppression might be instrumental to prevent ESRD and promote renal function recovery in clinical practice.

Drug Information available for: Lisinopril

Arm Intervention/treatment
Experimental: Lisinopril
Patients will receive, in addition to standard immunosuppressive therapy, lisinopril starting with 5 mg/day, then progressively up-titrated to reach the maximum tolerable dose (target dose) for 18 months.
Drug: Lisinopril
No Intervention: No intervention
Patients will receive only the standard immunosuppressive therapy.

Primary Outcome Measures :
  1. The extent of extracapillary proliferation on light microscopy, measured as % of total glomeruli with proliferative lesions at post-treatment repeat biopsy. [ Time Frame: Changes from baseline and 6 and 18 month. ]

Secondary Outcome Measures :
  1. Expression of parietal cell proliferation markers at glomerular level, graded on a scale of 0 to 3 (0: no staining, 1: mild, 2: moderate, 3: strong diffuse [ Time Frame: Changes from baseline and 6 and 18 month. ]
  2. Number of fibrosclerotic crescents [ Time Frame: Changes from baseline and 6 and 18 month. ]
  3. Glomerular Filtration Rate (GFR) measured by iohexol plasma clearance [ Time Frame: Changes from baseline and 6, 12 and 18 month. ]
