BACKGROUND: The aim of the present study was to assess the influence of diabetic and pre-diabetic state on the development of contrast-induced nephropathy (CIN) in chronic kidney disease patients undergoing coronary angiography. METHODS: A total of 421 patients with Cockcroft clearance between 15 and 60 ml/min were divided into three groups [diabetes mellitus (DM), n = 137; pre-diabetes (pre-DM), n = 140; and normal fasting glucose (NFG), n = 144]. CIN was defined as an increase of > or =25% in creatinine over baseline within 48 h of angiography, DM as glucose > or =126 mg/dl, pre-DM as glucose between 100 and 125 mg/dl and NFG as glucose <100 mg/dl. RESULTS: CIN occurred in 20% of the DM [relative risk (RR) 3.6, P = 0.001], 11.4% of the pre-DM (RR 2.1, P = 0.314) and 5.5% of the NFG group. The decrease of glomerular filtration rate (GFR) was higher in DM and pre-DM (P = 0.001 and P = 0.002, respectively). GFR < or =30 ml/min (RR 19.22), multivessel involvement (RR 7.59), hyperuricaemia (RR 3.95), use of angiotensin-converting enzyme inhibitors or angiotensin II receptor blocker (RR 2.70) and DM (RR 2.34) were predictors of CIN. Length of hospital stay was 2.45 +/- 1.45 day in DM, 2.27 +/- 0.68 day in pre-DM and 1.97 +/- 0.45 day in NFG (P < 0.001, DM vs NFG and P = 0.032, pre-DM vs NFG). The rate of major adverse cardiac events was 8.7% in DM, 5% in pre-DM and 2.1% in NFG (P = 0.042, DM vs NFG). Haemodialysis was required in 3.6% of DM and 0.7% in pre-DM (P = 0.036, DM vs NFG), and the total number of haemodialysis sessions during 3 months was higher in DM and pre-DM (P < 0.001). Serum glucose > or =124 mg/dl was the best cut-off point for prediction of CIN. CONCLUSION: Our data support that patients with DM are at a higher risk of developing CIN, but patients with pre-DM are not at as high a risk for developing CIN as diabetes patients.
