Article Synopsis
- Gentamicin, an antibiotic used to treat infections, can cause acute kidney injury (AKI) due to its nephrotoxic effects, especially in patients on high doses or long-term therapy.
- Researchers are exploring non-protein-coding RNAs, particularly microRNAs (miRNAs), as potential biomarkers for diagnosing and monitoring gentamicin-induced AKI.
- Changes in miRNA expression related to inflammation, cell death, and oxidative stress have been observed in response to gentamicin exposure, indicating their potential role in assessing kidney injury severity.
Introduction: Immunoglobulin A1 (IgA1) with galactose-deficient -glycans (Gd-IgA1) play a key role in the pathogenesis of IgA nephropathy (IgAN). Mucosal-tissue infections increase IL-6 production and, in patients with IgAN, are often associated with macroscopic hematuria. IgA1-secreting cell lines derived from the circulation of patients with IgAN, compared to those of healthy controls (HCs), produce more IgA1 that has glycans with terminal or sialylated -acetylgalactosamine (GalNAc).

A large group of drugs associated with AKI includes a considerable number of antimicrobials. Clinical manifestations range from mild forms of tubular damage to significant deterioration of renal function requiring renal replacement therapy.

The aims of this study were to track the 7-day time course of blood miRNAs in patients with sepsis treated with vancomycin, gentamicin, or a non-nephrotoxic antibiotic and miRNA associations with neutrophil gelatinase-associated lipokalin (NGAL), creatinine, procalcitonin, interleukin-6, and acute kidney injury (AKI) stage.
Methods: Of 46 adult patients, 7 were on vancomycin, 20 on gentamicin, and 19 on another antibiotic.
Background: IgA nephropathy (IgAN) primary glomerulonephritis is characterized by the deposition of circulating immune complexes composed of polymeric IgA1 molecules with altered O-glycans (Gd-IgA1) and anti-glycan antibodies in the kidney mesangium. The mesangial IgA deposits and serum IgA1 contain predominantly light (L) chains, but the nature and origin of such IgA remains enigmatic.
Methods: We analyzed L chain expression in peripheral blood B cells of 30 IgAN patients, 30 healthy controls (HCs), and 18 membranous nephropathy patients selected as disease controls (non-IgAN).
