Angiotensin-receptor blockers (ARBs) blunt progression of advanced diabetic nephropathy, but their long-term renal effects in other patients are not clear.
To examine the long-term renal effects of telmisartan versus placebo in adults at high vascular risk.
Randomized trial. Patients were randomly assigned by a central automated system between November 2001 and May 2004 and were followed until March 2008. Participants and investigators were blinded to intervention status.
Multicenter, multinational study.
5927 adults with known cardiovascular disease or diabetes with end-organ damage but without macroalbuminuria or heart failure who cannot tolerate angiotensin-converting enzyme inhibitors.
Telmisartan, 80 mg/d (nÂ = 2954), or matching placebo (nÂ = 2972) plus standard treatment for a mean of 56 months.
Composite renal outcome of dialysis or doubling of serum creatinine, changes in estimated glomerular filtration rate (GFR), and changes in albuminuria.
No important difference was found in the composite renal outcome with telmisartan (58 patients [1.96%]) versus placebo (46 patients [1.55%]) (hazard ratio, 1.29 [95% CI, 0.87 to 1.89]; PÂ = 0.20). Among the telmisartan and placebo groups, 7 and 10 patients had dialysis and 56 and 36 patients had doubling of serum creatinine, respectively (hazard ratio, 1.59 [CI, 1.04 to 2.41]; PÂ = 0.031). Albuminuria increased less with telmisartan than with placebo (32% [CI, 23% to 41%] vs. 63% [CI, 52% to 76%]; PÂ < 0.001). Decreases in estimated GFR were greater with telmisartan than with placebo (mean change in estimated GFR, âˆ’3.2 mL/min per 1.73 m2 [SD, 18.3] vs. âˆ’0.26 mL/min per 1.73 m2 [SD, 18.0]; PÂ < 0.001).
Only 17 participants had dialysis.
In adults with vascular disease but without macroalbuminuria, the effects of telmisartan on major renal outcomes were similar to those of placebo.
