The term autophagy usually refers to macroautophagy, which is one of three types of autophagy, alongside microautophagy and chaperone-mediated autophagy. Autophagy is activated by adenosine monophosphate-activated protein kinase (AMPK) and inhibited by mammalian target of rapamycin (mTOR) through their interference with Unc-51-like kinase 1 (ULK1). Dysregulated autophagy is deeply involved in autoimmune glomerular diseases. Upregulated autophagy can induce inflammation and activate innate and adaptive immunity. However, autophagy may also exert a protective role on podocytes, enhance endothelial cell function, and preserve proximal tubular epithelial cells during ischemic or endotoxic acute kidney injury (AKI). Hydroxychloroquine (HCQ) can downregulate increased autophagy and is widely used in lupus nephritis. HCQ causes alkalinization, which results in vacuolization of lysosomes and inhibition of their functions. By inhibiting autophagic activity, HCQ may reduce inflammation and innate immunity, inhibit the activation of T cells, restore the T helper 17/T regulator balance, restrict the production of pro-inflammatory cytokines, and modulate co-stimulatory molecules. This reduces the risk of flares, spares the dosage of glucocorticoids, improves lupus activity, and prevents the thrombotic effects of anti-phospholipid antibodies. Recent studies showed that HCQ can also reduce proteinuria in IgA nephropathy (IgAN) and membranous nephropathy (MN). Drugs that improve mitochondrial function or enhance autophagy, such as metformin, sodium-glucose co-transporter 2 (SGLT2) inhibitors or mTOR inhibitors, may exert protective effects on podocytes and reduce proteinuria in MN or focal segmental glomerulosclerosis (FSGS).</p>","PeriodicalId":16542,"journal":{"name":"Journal of Nephrology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technique has proved to be effective in removing uremic toxins previously deemed inaccessible due to their size or charge, as well as to their molecular interactions with blood proteins. In this context, this review provides a detailed explanation of the role of Polyester-polymer alloy (PEPA®) membranes and hemodiafiltration with endogenous reinfusion. The polyester-polymer alloy membrane is a three-layered dialysis membrane with adsorbent properties, representing an innovative approach to engineering the filter membrane to achieve adsorbent characteristics while maintaining biocompatibility with blood. Haemodiafiltration with endogenous reinfusion is a technique where a first filter separates plasma water from blood, then plasma water is led to a sorbent cartridge. After contact with the sorbent, the purified plasma water reconstitutes the whole blood, which is led to a second filter where diffusion takes place. Both techniques are efficacious in removing middle-molecular weight molecules and protein-bound toxins, and have a role in reducing inflammation and erythropoietin resistance. However, the additional clinical advantage of adsorption is partially offset by lack of selectivity in the absorption process, potentially resulting in the loss of micro- and macronutrients or drugs. Therefore, further studies are encouraged to evaluate the impact of absorption on patient outcomes and clinical applicability in certain medical conditions.</p>","PeriodicalId":16542,"journal":{"name":"Journal of Nephrology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143615763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
