title: Hereditary nephritis and hypoplastic dysplastic nephropathy: hydroxylysine glycoside excretion and the glomerular basement membrane.
abstract: Eleven children aged 5 to 15 years with hereditary nephritis and twelve children with hypoplastic dysplastic nephropathy were studied. The children with hereditary nephritis were divided into 2 groups while correlating the level of renal excretion of hydroxylysine glycosides (HOLG) with ultrastructure of glomerular basement membrane. The first group was characterized by decreased urinary excretion of HOLG and extremely thin basement membranes, the second one - by increased HOLG excretion and thickened membranes, The children with hypoplastic dysplastic nephropathy which were divided into 2 groups according to HOLG excretion differed in presence or absence of anatomic anomalies and in the number of connective tissue dysembryogenetic stigmata. The data are suggestive of an important role and diversity of metabolic derangement of the collagenic component of basement membranes in the pathogenesis of the diseases studied.
