Radiocontrast-induced nephropathy (RCIN) represents an increasingly common cause of treatment-related renal failure and increases mortality independent of other risk factors. Major risk factors for RCIN include chronic renal insufficiency, diabetes mellitus (especially when accompanied by renal insufficiency), any condition associated with decreased effective circulating volume, and use of larg...

Modern iodinated contrast media (CM) consist of one or two tri-iodobenzene rings. They differ from each other in the composition of the side chains, creating different molecules and thus different brand substances. After intravascular administration, all CM are distributed rapidly into intravascular and extracellular fluids. They are eliminated solely by glomerular filtration. In patients with ...

This is a good quality study that demonstrates a dramatic decrease in the incidence of contrast nephropathy with the use of sodium bicarbonate infusion prior to contrast administration. However, this study does have some shortcomings. The small sample size resulted in relatively wide confidence intervals and made the generally low attrition rate more significant. The data was not analyzed on an...

Development of contrast-induced nephropathy (CIN), ie, a rise in serum creatinine by either ≥0.5 mg/dL or by ≥25% from baseline within the first 2-3 days after contrast administration, is strongly associated with both increased inhospital and late morbidity and mortality after invasive cardiac procedures. The prevention of CIN is critical if long-term outcomes are to be optimized after percutan...

We previously reported that insufficiency of antithrombin III (ATIII), the major anti-coagulation molecule in vivo, exacerbated renal ischemia-reperfusion injury in animal models and possibly humans. In the present study, we investigated the relationship between ATIII level and contrast induced nephropathy (CIN) in patients and examined therapeutic effect of ATIII on CIN in Sprague-Dawley rats....

Objective(s): This study aimed to show the effects of thymoquinone, which is known for its antioxidant, anti-inflammatory, and renal protective effects in contrast-induced nephropathy.Materials and Methods: This is an experimental study in rats. 7 groups were included within the scope of our study: sham-vehicle (n=3), premedication-contr...

Sir, The paper by Kimmel et al. [1] concludes that cystatin C blood level variations are a more reliable parameter than serum creatinine increments for the diagnosis of contrastinduced nephropathy (CIN). However, this conclusion does not seem sufficiently supported by the data to us. Since the definition of CIN is based on serum creatinine variations, it is not clear what the meaning is of the ...
