Key result

Aliskiren treatment for 28 days reduced blood pressure to wild-type levels and ameliorated renal interstitial fibrosis and inflammation in 10-month-old renin transgenic mice.

Why the study?

Does aliskiren reverse renal disease and cardiac hypertrophy in a transgenic mouse model of hypertensive chronic kidney disease?

Population

10-month-old renin transgenic mice and age-matched wild-type mice

Comparison

Aliskiren administered for 28 days vs Placebo, untreated wild-type mice, and hydralazine

Design

Preclinical

Follow-up

28 days

Implication

Preclinical data in renin transgenic mice are hypothesis-generating; leaves open whether aliskiren reverses renal fibrosis in human hypertensive CKD.

Structured PICO

Does aliskiren reverse renal disease and cardiac hypertrophy in a transgenic mouse model of hypertensive chronic kidney disease?

P
Population
10-month-old renin transgenic mice with elevated blood pressure and slow decline of renal function treated for 28 days.
I
Intervention
Aliskiren administered for 28 days
C
Comparator
Placebo (for transgenic mice), untreated wild-type mice, and hydralazine (as a blood pressure normalization control)
O
Outcome
Blood pressure, proteinuria, cardiac hypertrophy, and cardiac fibrosissurrogate

Direct renin inhibition with aliskiren reverses renal fibrosis and cardiac hypertrophy in a hypertensive mouse model, demonstrating nephroprotective effects independent of blood pressure lowering.

Cite This Study

Kavvadas et al. (2013) studied Hypertensive chronic kidney disease. Aliskiren vs. Placebo was evaluated on Blood pressure, proteinuria, cardiac hypertrophy, and renal fibrosis. Aliskiren treatment for 28 days reduced blood pressure to wild-type levels and ameliorated renal interstitial fibrosis and inflammation in 10-month-old renin transgenic mice.
