Introduction. Retrospective observational data show that ACE-inhibitor therapy delays renal failure and improves life expectancy in Alport patients with proteinuria. The EARLY PRO-TECT Alport trial assesses the safety and efficacy of early therapy onset with ramipril in pediatric Alport patients. Methods and analysis. This double-blind, randomized, placebo-controlled, multicenter phase III tria...

Alport disease is caused by mutations in genes encoding the alpha3, alpha4, or alpha5 chains of type IV collagen, which form the collagenous network of mature glomerular basement membrane (GBM). In the absence of alpha3, alpha4, alpha5 (IV) collagen, alpha1, alpha2 (IV) collagen persists, which ordinarily is found only in GBM of developing kidney. In addition to dysregulation of collagen IV, Al...

BACKGROUND Alport syndrome is a progressive genetic disease which is characterised by glomerulonephritis, sensorineural deafness and ocular abnormalities. We aimed to present a clinical case of a patient with Alport syndrome with spontaneous anterior lens capsule rupture. CASE REPORT A 16-year-old male with histologically proven Alport syndrome was hospitalised in the Department of Ophthalmol...

BACKGROUND Alport syndrome is an inherited disease resulting in kidney failure, hearing loss and ocular abnormalities. Alport syndrome is however often unrecognized, and the aim of this study was to characterize the associated but rarely described peripheral retinopathy and determine whether its demonstration was diagnostically helpful. METHODS Index cases were diagnosed with Alport syndrome ...

Alport syndrome, also termed hereditary nephritis, was initially described in 1927 by A.C. Alport [1] as an inherited kidney disease characterized by hematuria and sensorineural deafness. Later, ocular lesions were also associated with the syndrome and, with the introduction of the electron microscope, irregularities and disruptions in the glomerular basement membrane (GBM) were shown to be typ...

Few prospective, randomized controlled clinical trials address the diagnosis and management of patients with Alport syndrome or thin basement membrane nephropathy. Adult and pediatric nephrologists and geneticists from four continents whose clinical practice focuses on these conditions have developed the following guidelines. The 18 recommendations are based on Level D (Expert opinion without e...

Introduction Background. Alport syndrome is a hereditary nephritis that may lead to end-stage renal disease (ESRD) in Alport syndrome is a progressive hereditary nephroyoung adult life and is often associated with sensorineupathy associated with characteristic ultrastructural ral deafness and/or ocular abnormalities. The majority abnormalities of the glomerular basement membrane of families are...

Alport syndrome is a rare hereditary disease that is associated with retinal abnormalities such as dot-and-fleck retinopathy and temporal macular thinning. The main pathophysiological process of Alport syndrome is loss of the collagen network in the basement membrane. However, the alterations in each retinal layer have not been fully evaluated. In the case presented here, we evaluated the retin...

Alport syndrome is caused by mutations in the genes encoding α3, α4, or α5 (IV) chains. Unlike X-linked Alport mice, α5 and α6 (IV) chains are detected in the glomerular basement membrane of autosomal recessive Alport mice, however, the significance of this finding remains to be investigated. We therefore generated mice lacking both α3 and α6 (IV) chains and compared their renal function and su...

BACKGROUND Alport syndrome is the most common form of hereditary nephritis and is mainly caused by mutations in the COL4A5 gene, which shows the X-linked form. It is well known that some male Alport syndrome cases show a relatively mild phenotype, but few molecular investigations have been conducted to clarify the mechanism of this phenotype. Methods and results. This report concerns an 8-year-...
