Abstract

Background: Low-dose aspirin is widely recommended for patients at high risk for cardiovascular disease (CVD); however, it remains uncertain whether long-term treatment adversely affects renal function in patients with diabetes. We investigated whether long-term low-dose aspirin affects renal dysfunction in patients with diabetes.

Methods: We conducted a randomized controlled trial (RCT), the Japanese Primary Prevention of Atherosclerosis with Aspirin for Diabetes (JPAD) trial, to evaluate low-dose aspirin as primary prevention for CVD in patients with type 2 diabetes. We followed the patients with negative urine dipstick albumin of the JPAD trial in a cohort study after the RCT period was completed. Patients were randomly allocated to receive aspirin (81 mg or 100 mg daily, aspirin group) or no aspirin (no aspirin group). After the RCT, the treating physician decided whether to administer aspirin. We evaluated the incidence of positive urine dipstick albumin and annual changes in estimated glomerular filtration rate (eGFR).

Results: Positive urine dipstick albumin developed in 297 patients in the aspirin group (n = 1,075) and 270 patients in the no aspirin group (n = 1,098) during follow-up (median, 8.5 years). Intention-to-treat analysis showed low-dose aspirin did not increase the incidence of positive urine dipstick albumin (hazard ratio [HR], 1.17; 95% confidence interval [CI], 0.995-1.38). On-treatment analysis yielded similar results (HR, 1.08; 95% CI, 0.92-1.28). Multivariable analysis showed the incidence of positive urine dipstick albumin was higher among the elderly and those with elevated serum creatinine, high hemoglobin A1c, or high blood pressure; however, low-dose aspirin did not increase the risk of positive urine dipstick albumin. There were no significant differences in annual changes in eGFR between the groups (aspirin, -0.8 ± 2.9; no aspirin, -0.9 ± 2.5 ml/min/1.73 m(2)/year).

Conclusion: Long-term low-dose aspirin does not affect eGFR and positive urine dipstick albumin in patients with type 2 diabetes.

Positive urine dipstick albumin developed in 297 patients in the aspirin group and 270 patients in the no aspirin group. The intention-to-treat analysis showed that low-dose aspirin did not increase the incidence of positive urine dipstick albumin (HR, 1.17; 95% CI, 0.995 to 1.38; log-rank P = 0.057)

In the on-treatment analysis, low-dose aspirin had no effect on the incidence of positive urine dipstick albumin (HR, 1.08; 95% CI, 0.92 to 1.28; log-rank P = 0.32).
