Aim: To analyze the clinical manifestation of Alport syndrome, especially the ocular features.
Methods: The physical, ophthalmologic and audiologic examination results of thirty-two patients with Alport syndrome were analyzed retrospectively.
Results: Thirty (93.7%) patients had some family history. All patients had renal disease: eighteen (56.3%) patients with chronic renal failure, four (12.5%) patients with renal insufficiency, and the other ten (31.3%) patients with hematuria. Twenty (62.5%) patients had sensorineural deafness. Thirteen (40.6%) patients had ocular deformity, five (15.7%) patients had typical ocular changes: three patients with anterior lenticonus, and two patients with macular flecks.
Conclusion: Ocular anomalies are not requisite for the diagnosis of Alport syndrome. But its typical ocular features should be recognized by the ophthalmologists which supports the diagnosis.

We present 3 cases of bilateral anterior lens capsule rupture, all leading to a subsequent diagnosis of Alport syndrome. Clinicians should be alert to the ocular and systemic features of Alport syndrome, especially when presented with a spontaneous rupture of the anterior lens capsule in young males. Ophthalmologists are often the first contact for patients with Alport syndrome, and a sound knowledge of the associated features will enable timely referral to other members of a multidisciplinary team required to treat such patients.

Introduction: Large-scale trials showed positive outcomes of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in adults with chronic kidney disease (CKD). Whether the use of SGLT2i is safe and effective in patients with the common hereditary CKD Alport syndrome (AS) has not yet been investigated specifically in larger cohorts.
Methods: This observational, multicenter, international study (NCT02378805) assessed 112 patients with AS after start of SGLT2i.

Background: Alport Syndromes (AS) are the second leading genetic cause of Kidney Failure (KF). Whether multiple kidney cysts (MKC) phenotype belongs to the AS spectrum remains debated.
Methods: This multicenter retrospective study focused on patients genotyped with pathogenic COL4A3, COL4A4, or COL4A5 variants (classified as ACMG-AMP 4 or 5) between January 2011 and January 2023 across four French university hospitals.

Mitochondrial dysfunction is a critical factor in the pathogenesis of Alport syndrome (AS), contributing to podocyte injury and disease progression. Ezetimibe, a lipid-lowering drug, is known to inhibit cholesterol and fatty acid uptake and to reduce triglyceride content in the kidney cortex of mice with AS. However, its effects on lipid droplet (LD) utilization by mitochondria have not been explored.

Purpose: Alport syndrome (AS) is a genetic condition caused by a dysfunctional collagen (IV) α3α4α5 heterotrimer, leading to basement membrane instability and, ultimately, abnormalities in the kidney, inner ear, and eyes. This study aimed to characterize ocular pathology of AS by focusing on inflammatory and fibrotic markers.
Methods: Col4a3tm1Dec knockout (KO) mice eyes were evaluated for the localization of collagen (IV) α3 and collagen (IV) α4, then stained for transforming growth factor-β1 (TGF-β1), TGF-β2, connective tissue growth factor (CTGF), and β-catenin.
