Curcuminoids and Contrast-induced Acute Kidney Injury

This study was a single-center, prospective, double-blinded, randomized placebo-controlled trial in CKD patients undergoing elective coronary angiography (CAG) at Vajira hospital from October 2018 to March 2019. Patients were stratified according to baseline estimate glomerular filtration rate (eGFR) and diabetes status. They were randomized to Curcuminoids 1,500 milligrams per day starting 3 days before and 2 days after coronary procedure or placebo. The primary outcome was the development of CI-AKI, defined as serum creatinine rising ≥ 0.3 mg/dL within 48 hours after coronary angiography. The secondary outcomes were overall AKI incidences within 7 days after CAG, changes in eGFR, IL-6 hs-CRP, and other adverse events. A total of 60 patients were enrolled( 30 in curcuminoids group, and 30 in the control group). Overall AKI developed in 5 patients in control group and none in curcuminoids group (16.67% versus 0%, p-value 0.052). The results showed that curcuminoids could preserve changes in eGFR compared to the placebo group (-1.5 vs 2.5 mL/min/1.73m2, p-value \<0.001 within 48 hours and -4 versus 1 mL/min/1.73m2, p-value 0.002 within 7 days). The high-sensitive C-reactive protein (hs-CRP) and IL-6 levels were not different between patients receiving curcuminoids and placebo. In curcuminoids group, 3 patients developed mild nausea and diarrhea that improved with supportive care. No serious adverse events were found in both groups.
