Demographic data, comorbidities, biopsy features and biochemical markers were collected for a minimum of 12 months following biopsy diagnosis. A multivariable analysis using Cox regression was performed to examine their association with renal progression. <b>Results:</b> A total of 104 patients met the inclusion criteria and were followed for a median of 72 months. The cohort had a mean age at presentation of 45 years, with a predominantly male population. Most patients presented with haematuria and non-nephrotic range proteinuria. We stratified patients into three risk categories: low risk, intermediate risk, and high risk. Twenty-eight patients (26.92%) developed kidney failure and 15 patients (14.4%) experienced a > 20 mL/min eGFR decline within the first 12 months. The multivariable analysis revealed the following key factors associated with kidney failure: additional renal pathology on biopsy (HR 3.90, 95% CI 1.63-9.29), proteinuria (HR 1.15, 95% CI 1.02-1.29) and moderate-severe interstitial fibrosis/tubular atrophy (T2) (HR 7.00, 95% CI 2.32-21.05). There were 17 deaths (16.3%) in the cohort, with a mean survival time of 167.8 months (95% CI 152.6-183.1). <b>Conclusion:</b> In contrast to earlier reports from Australia, our findings emphasise that the progression to kidney failure is not uncommon in IgAN. We identified several predictors of the renal progression that are consistent with the previous studies. This highlights the need for a change in clinical management, as IgAN should no longer be considered a benign condition.</p>","PeriodicalId":14177,"journal":{"name":"International Journal of Nephrology","volume":"2025 ","pages":"9976879"},"PeriodicalIF":1.7,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11968155/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This leads to oligonephropathy, which is associated with serious consequences for health in the later stages of life. While the clinical aspects have been intensely investigated, only few pathological data point to the initial traces left by the noxae. Up to this date, only the reduction in the width of the nephrogenic zone (NZ) and the lack of here occurring basophilic S-shaped bodies were reported. <b>Methods and Materials:</b> The relationship between the arising nephron and its structural neighbors changes throughout the developmental progress. Locally, this determines the vertical width of the NZ reflected by the radial expansion of both the parenchyma and the interstitium. Since information about the origin, the site, and the involved structures is not available, the related microanatomical features were recorded. <b>Results:</b> The data reveal that the renal vesicles, comma-shaped bodies, and S-shaped bodies are unequally distributed in the NZ. Due to their progressive sizes, it has an influence on the local vertical width of the NZ. This parameter is registered as the distance between the inner side of the renal capsule and the proximal pole of the respective stage of the nephron anlage. The vertical width can be further subdivided: the constant height of the district of progenitor cell recruitment and the variable height of the area of nephron shaping. Exclusively here, the radial expansion of the shaping nephron stages can be noticed. It starts at the section border between the head and the conus of the related collecting duct ampulla by positioning the primitive renal vesicle. While the respective proximal pole stays mounted next to the connecting tubule of a previously developed nephron, the distal pole sticks between the head and the conus at the CD ampulla for linking the future connecting tubule. This causes that henceforth the medial aspect of the extending renal vesicle, comma-shaped body, or S-shaped body stages radially expands in close proximity to the elongating conus of the CD ampulla. <b>Conclusion:</b> Between the arising nephron stages and the elongating conus of the CD ampulla, a linked radial expansion occurs.
