The clinical spectrum of Henoch–Schönlein purpura nephritis (HSPN), now known as IgA vasculitis‐associated nephritis (IgAVN), ranges from isolated microscopic haematuria to nephrotic syndrome, progressive glomerulonephritis, and kidney failure. The outcome also varies, and the management of IgAVN is controversial. The presence of nephrotic state at disease onset is thought to be a risk...
Aim
Accurate and precise estimation of glomerular filtration rate (GFR) is essential in kidney disease. We evaluated the usefulness of the mean of creatinine clearance (CCr) and urea clearance (CUN) examined over a 1‐h urine collection period (1‐h (CCr + CUN)/2) in a retrospective, cross‐sectional study across two centres, as a relatively simple method for estimating GFR in children.
