In July and August 2010 he was admitted twice with relapses characterised by acute kidney injury (AKI, creatinine 519 μmol/L); each of these relapses was heralded by a worsening of his rash but with no reduction in serum albumin or deterioration in uPCR (serum albumin 37 g/L and uPCR 2.40 g/g (271 g/mol) in August). This evidence concerns the gene ALB and acute kidney injury.
