If it weren’t for your kidney’s, where would you be? You’d be in the hospital or infirmary (with apologies to Fred Dagg). The heart and kidneys are not just linked by a pipe, but the health of one is very much dependent on the health of the other. Acute Kidney Injury (AKI) is a phenomenon whereby there is a sudden loss of all or some of the kidneys’ filtration ability. This can have dire immediate consequences with a greater increased risk of mortality & longer hospital stays. It can also increase the risk of developing a chronic kidney disease or even later cardiac problems. Unfortunately, AKI is devilishly difficult to detect, and therefore there are no early treatments. It is also very common – some 4-5% of all hospital patients. Those with heart failure are particularly vulnerable.
IDENTAKIT-HF is a new project all about identifying AKI biomarkers inheart failure. Two weeks ago it enrolled its first patient. It is a collaborative project involving myself, the Christchurch Heart Institute, and a biomarker laboratory in Prince of Wales Hospital, Sydney headed by former Christchurch nephrologist Professor Zoltan Endre. Not only are blood samples being taken from patients with heart failure and potential AKI, but also urine samples. This is because various novel protein markers in the urine appear to respond much more quickly to AKI than markers in the blood. It is now recognised, that not one marker, but a panel of markers is needed to identify AKI and provide information about how to target any treatments. IDENTAKIT-HF will identify the likely members of such a panel and then test if they really do identify the disease and predict its course. This will form the platform for future intervention trials to develop treatments and improve patient outcomes.
