title: Haematuria: the forgotten CKD factor?
abstract: Haematuria is a frequent manifestation of glomerular disease. However, nephrologists devote more attention to the monitoring and therapeutic targeting of another key manifestation of glomerular injury, proteinuria. Recent reports have propelled haematuria to the forefront of clinical nephrology. Thus, glomerular macroscopic haematuria is associated with the development of acute kidney injury (AKI) with predominant tubular cell damage and there is increasing evidence for the negative impact of glomerular haematuria-associated AKI on long-term renal function outcome both in the context of IgA nephropathy and in anticoagulated patients. In addition, an epidemiological association between isolated microscopic haematuria in young adults and long-term incidence of end-stage renal disease has been described. Finally, a clearer understanding of how haematuria may cause tubular injury is emerging through detailed histological assessment of human biopsies and experimental models of haemoglobin-mediated nephrotoxicity.
