The development of glomerulonephritis causes glomerular injury and renal
dysfunction and is thought to increase renin release, thus activating the
renin-angiotensin system (RAS). The aims of this study were to demonstrate
activation of the intrarenal RAS and determine the effects of direct renin
inhibition (DRI) on the progression of glomerulonephritis. Rats were treated with
anti-Thy1.1 antibody with or without DRI, aliskiren (30 mg/kg/d). In the
glomerulonephritic rats, protein, microalbumin excretion levels, urinary
angiotensinogen excretion, glomerular expansion score and intrarenal transforming
growth factor-? and plasminogen activator inhibitor-1 mRNA levels were augmented
compared with control rats; however, hypertension was not observed in the
glomerulonephritic rats, and aliskiren treatment did not modify their blood
pressure. The increases in urinary protein (94.7 ± 13.0 mg/d) and microalbumin
(7.52 ± 2.6 mg/d) excretion were reduced by aliskiren (43.6 ± 4.5 mg/d of protein
and 2.57 ± 0.7 mg/d of microalbumin). Furthermore, the progression of glomerular
expansion and elevation of intrarenal transforming growth factor-? and
plasminogen activator inhibitor-1 levels were prevented by aliskiren.
Importantly, aliskiren suppressed the augmentation of urinary angiotensinogen
levels, the increased angiotensinogen expression in the kidneys and the increases
in Ang II levels in renal medulla induced by the anti-Thy1.1 antibody. These
results suggest that DRI with aliskiren prevents intrarenal RAS activation
leading to mitigation of the development of glomerulonephritis. In addition, the
renoprotective effects of DRI on glomerulonephritis occur in a blood
pressure-independent manner. Accordingly, treatment with aliskiren may be an
effective approach to treat glomerulonephritis and other intrarenal
RAS-associated kidney diseases.
