The Role of Proprotein-convertase-subtilisin/Kexin-type 9 in Kidney Damage in Nephrotic Syndrom

Sponsor: Kolding Sygehus

Summary

Nephrotic syndrome (NS) is characterized by gross proteinuria (\>3.5 g/day), hypoalbuminaemia, edema and often hyperlipidemia. Hyperlipidemia is correlated with increased morbidity and mortality. The study aim is to investigate the role of the protein convertase subtilisin/kexin type 9 (PCSK9) in hyperlipidemia of NS, which has been suggested to play an important role. This is done by testing the following hypotheses: 1. PCSK9 is increased in patients with NS and hyperlipidemia compared to kidney-healthy controls 2. The level of PCSK9 in plasma correlates to the degree of proteinuria. 3. PCSK9 i increased in the kidney tissue of patients with NS The study will compare plasma levels of PCSK9 in correlation with degree of protein in the urine between test persons with NS and kidney healthy controls. Furthermore the investigators will study the the degree of PCSK9 in the kidney in biopsies obtained from test persons with nephrotic syndrome and test persons without proteinuria.
