IMPORTANCE: The optimal blood pressure (BP) target remains debated in nondiabetic
patients with chronic kidney disease (CKD). OBJECTIVE: To compare intensive BP
control (<130/80 mm Hg) with standard BP control (<140/90 mm Hg) on major renal
outcomes in patients with CKD without diabetes. DATA SOURCES: Searches of PubMed,
MEDLINE, Embase, and Cochrane Library for publications up to March 24, 2016.
STUDY SELECTION: Randomized clinical trials that compared an intensive vs a
standard BP target in nondiabetic adults with CKD, reporting changes in
glomerular filtration rate (GFR), doubling of serum creatinine level, 50%
reduction in GFR, end-stage renal disease (ESRD), or all-cause mortality. DATA
EXTRACTION AND SYNTHESIS: Random-effects meta-analyses for pooling effect
measures. Meta-regression and subgroup analyses for exploring heterogeneity. MAIN
OUTCOMES AND MEASURES: Differences in annual rate of change in GFR were expressed
as mean differences with 95% CIs. Differences in doubling of serum creatinine or
50% reduction in GFR, ESRD, composite renal outcome, and all-cause mortality were
expressed as risk ratios (RRs) with 95% CIs. RESULTS: We identified 9 trials with
8127 patients and a median follow-up of 3.3 years. Compared with standard BP
control, intensive BP control did not show a significant difference on the annual
rate of change in GFR (mean difference, 0.07; 95% CI, -0.16 to 0.29 mL/min/1.73
m2/y), doubling of serum creatinine level or 50% reduction in GFR (RR, 0.99; 95%
CI, 0.76-1.29), ESRD (RR, 0.96; 95% CI, 0.78-1.18), composite renal outcome (RR,
0.99; 95% CI, 0.81-1.21), or all-cause mortality (RR, 0.95; 95% CI, 0.66-1.37).
Nonblacks and patients with higher levels of proteinuria showed a trend of lower
risk of kidney disease progression with intensive BP control. CONCLUSIONS AND
RELEVANCE: Targeting BP below the current standard did not provide additional
benefit for renal outcomes compared with standard treatment during a follow-up of
3.3 years in patients with CKD without diabetes. However, nonblack patients or
those with higher levels of proteinuria might benefit from the intensive
BP-lowering treatments.
