ABSTRACT
This study assesed the prevalence of histopathological changes in renal biopsies from healthy individuals, and the association with age, sex and smoking. Donor biopsies from 109 subjects were obtained from living kidney donors, and blood and urine samples were collected together with medical history. All biopsies were scored according to the Banff '97 classification with some modifications. The parameters included in this study were tubular atrophy, interstitial fibrosis, glomerulosclerosis, arteriosclerosis, arteriolohyalinosis and a sclerosis score. An alternative scoring system for tubular atrophy was examined (using ≤5% rather than <1% as a cut-off for grade 0). Glomerular filtration rate was measured in most cases as chromium ethylenediaminetetra-acetic acid (Cr-EDTA) clearance. Age was a significant predictor for tubular atrophy, fibrosis and sclerosis. Pack-years of smoking increased the risk of tubular atrophy, fibrosis and arteriolohyalinosis. The alternative scoring of tubular atrophy showed a stronger association with smoking, but a weaker association with age, compared with the original one. Limited histopathological changes are common in healthy kidney donors around 50 years of age with normal kidney function. We propose that a cut-off of ≤5% yields a better definition of grade 0 tubular atrophy compared with the established cut-off of >0%.
