Different ways of diagnosing selective glomerular hypofiltration syndromes such as shrunken pore syndrome and the associated increase in mortality
BackgroundIn 2015, a selective decrease in the glomerular filtration of middle-sized molecules such as cystatin C compared to small molecules such as creatinine was first described and tentatively termed “Shrunken pore syndrome.” Numerous studies have thereafter found an association between this syndrome (defined by a low eGFRcystatin C to eGFRcreatinine ratio) and mortality and morbidity.
