ABSTRACT
Objective Systematic review the effect and side effect of Probucol on contrast-induced acute kidney injury (CIAKI), and to evaluate the characteristics and strength of the protective effect. Methods Electronic search studies from databases published in English and Chinese before March 2014, and hand searches of relevant randomized controlled trials of references. Features, the quality of research and valid data of included studies were extracted, then using RevMan 5.0 software to conduct a Meta-analysis base on Cochrane systematic review methods. Results A total of 11 literatures described eight randomized controlled trials involving 1938 cases of patients evaluated the effect of Probucal on CIAKI. A total of seven studies involving 1,298 patients, compared the incidence of CIAKI, the total incidence rate was 10.9%(141/1298), CIAKI incidence was 5.7%(37/652) in the Probucal group and 16.1%(104/646) in the control group (RR 0.37, 95%CI 0.26~0.53). Lower postoperative creatinine values was observed in Probucol group, compared with the control group on the first day Weighted Mean Difference (WMD-6.76, 95%CI-9.33~-4.20)μmol/L, the second day (WMD-16.90, 95%CI-22.61~-11.19)μmol/L, the third day(WMD-11.05, 95%CI-17.65~-4.45)μmol/L, and lower peak postoperative creatinine than the control group[(WMD- 14.58, 95%CI- 19.00 ~ - 10.16)μmol/L]. Probucol group with lower postoperative urinary KIM-1[(WMD-3.64 , 95%CI-3.72~-3.57) ng/ml], and the serum CysC was also low. Conclusions Preoperative or postoperative oral Probucol has a protective effect on CIAKI, can reduce the rise of postoperative renal injury indicators of coronary angiography or coronary intervention, such as serum creatinine and CysC, and CIAKI can be reduced by about 60%, no significant side effects observed.
