Acute kidney injury (AKI) is common and costly.1 Although patients who suffer an episode of AKI may recover, many will go on to develop cardiovascular disease and chronic kidney disease (CKD). Cardiovascular disease is an important complication of AKI.2 Similar to AKI, CKD and kidney transplantation and kidney donation associations with cardiovascular disease.1 The risk of cardiovascular disease complications is also increased in patients with inflammatory diseases that affect the kidneys, such as vasculitis.
Currently, there are no reliable biomarkers that will identify those patients with kidney disease that will go on to develop cardiovascular disease. This study will explore the potential of manganese-enhanced magnetic resonance imaging (MEMRI) to act as a biomarker of AKI and its cardiovascular and renal complications. An analogue of calcium, manganese is readily taken-up into viable cells where it increases T1 relaxivity. Preliminary data show rapid manganese uptake in the heart and kidneys of healthy subjects.
The investigators propose to use MEMRI to demonstrate differences in renal and myocardial calcium handling in patients with acute insults (such as AKI, transplant rejection, donation or episodes of rejection or new vasculitis presentations) or improvements (such as transplantation). The investigators will also investigate whether these abnormalities reverse in those whose injury resolves or persist in those who clearly develop CKD, or who are at risk of future cardiovascular disease and CKD.
