abstract = {Acute kidney injury (AKI) corrupts the outcome of about
$50\%$ of all critically ill patients. We investigated the
possible contribution of the pathology acidemia on the
development of AKI. Pigs were exposed to acidemia, acidemia
plus hypoxemia or a normal acid-base balance in an
experimental setup, which included mechanical ventilation
and renal replacement therapy to facilitate biotrauma caused
by extracorporeal therapies. Interestingly, extensive
histomorphological changes like a tubular loss of cell
barriers occurred in the kidneys after just 5 hours exposure
to acidemia. The additional exposure to hypoxemia aggravated
these findings. These 'early' microscopic pathologies
opposed intra vitam data of kidney function. They did not
mirror cellular or systemic patterns of proinflammatory
molecules (like TNF-α or IL 18) nor were they detectable by
new, sensitive markers of AKI like Neutrophil
gelatinase-associated lipocalin. Instead, the data suggest
that the increased renal proton excretion during acidemia
could be an 'early' first hit in the multifactorial
pathogenesis of AKI.},
