Inhibitors of Angiotensin II in Proteinuric Mesangioproliferative Glomerulonephritis

2014-08-27 03:14:00 | BioPortfolio

Summary

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.

Description

After signing informed consent, enrolled patients started treatment with ACEi. We decided to prescribe to all patients the same drug (ramipril) at the same dosage (5 mg/day). All patients were examined every 2 months during the first year of follow-up and every 6 months thereafter. At each visit, they underwent a complete physical examination. If the target blood pressure of <140/90 mmHg was not achieved with ramipril monotherapy, addition of other antihypertensive drug(s) was allowed. Patients complaining adverse side effects attributed to ramipril were switched to losartan (50 mg/day). The patients were also prescribed a normal protein (1 gram/kg/day) and moderately salt-restricted (6-8 grams/day) diet throughout the study.

Medical and Biotech [MESH] Definitions

Glomerulonephritis associated with autoimmune disease SYSTEMIC LUPUS ERYTHEMATOSUS. Lupus nephritis is histologically classified into 6 classes: class I - normal glomeruli, class II - pure mesangial alterations, class III - focal segmental glomerulonephritis, class IV - diffuse glomerulonephritis, class V - diffuse membranous glomerulonephritis, and class VI - advanced sclerosing glomerulonephritis (The World Health Organization classification 1982).

A chronic form of glomerulonephritis characterized by deposits of predominantly IMMUNOGLOBULIN A in the mesangial area (GLOMERULAR MESANGIUM). Deposits of COMPLEMENT C3 and IMMUNOGLOBULIN G are also often found. Clinical features may progress from asymptomatic HEMATURIA to END-STAGE KIDNEY DISEASE.

A type of glomerulonephritis that is characterized by the accumulation of immune deposits (COMPLEMENT MEMBRANE ATTACK COMPLEX) on the outer aspect of the GLOMERULAR BASEMENT MEMBRANE. It progresses from subepithelial dense deposits, to basement membrane reaction and eventual thickening of the basement membrane.

Chronic glomerulonephritis characterized histologically by proliferation of MESANGIAL CELLS, increase in the MESANGIAL EXTRACELLULAR MATRIX, and a thickening of the glomerular capillary walls. This may appear as a primary disorder or secondary to other diseases including infections and autoimmune disease SYSTEMIC LUPUS ERYTHEMATOSUS. Various subtypes are classified by their abnormal ultrastructures and immune deposits. Hypocomplementemia is a characteristic feature of all types of MPGN.

A long-acting angiotensin-converting enzyme inhibitor. It is a prodrug that is transformed in the liver to its active metabolite ramiprilat.
