Etiological spectrum and short-term outcomes of acute kidney injury in hospitalised patients of uncertain aetiology who underwent percutaneous renal biopsy.
J Pak Med Assoc
January 2025
Department of Nephrology, Sindh Institute of Urology and Transplantation, Karachi, Pakistan.
Objectives: To analyse the aetiological spectrum, clinical presentation and short-term renal outcomes of patients with acute kidney injury of uncertain aetiology subjected to percutaneous renal biopsy.
Methods: The prospective, cohort study was conducted at the Sindh Institute of Urology and Transplantation, Karachi, from March 1 to October 30, 2024, and comprised hospitalised acute kidney injury patients of either gender aged 18- 75 years who had been subjected to percutaneous renal biopsy. The patients were followed up for at least three months from the time of the biopsy.
[Clinicopathological significance and prognostic value of serum 25-hydroxyvitamin D level in children with IgA vasculitis nephritis].

Department of Pediatrics, Jinling Hospital, Medical School of Nanjing University, Nanjing 210000, China.
Objectives: To study the significance of serum 25-hydroxyvitamin D [25-(OH)D] level in the clinicopathological characteristics and prognosis of children with immunoglobulin A vasculitis nephritis (IgAVN).
Methods: A retrospective analysis was conducted on the clinical data of children with IgAVN who underwent renal biopsy at Suzhou Hospital Affiliated to Anhui Medical University and Jinling Hospital of the Medical School of Nanjing University from June 2015 to June 2020. Based on serum 25-(OH)D level, the patients were divided into a normal group and a lower group.
Single-cell transcriptomics in a child with coenzyme Q10 nephropathy: potential of single-cell RNA sequencing in pediatric kidney disease.

January 2025
Department of Translational Medicine, Seoul National University College of Medicine, Seoul, Republic of Korea.
Background: Coenzyme Q10 (CoQ10) nephropathy is a well-known cause of hereditary steroid-resistant nephrotic syndrome, primarily impacting podocytes. This study aimed to elucidate variations in individual cell-level gene expression in CoQ10 nephropathy using single-cell transcriptomics.
Methods: We conducted single-cell sequencing of a kidney biopsy specimen from a 5-year-old boy diagnosed with a CoQ10 nephropathy caused by a compound heterozygous COQ2 mutation complicated with immune complex-mediated glomerulonephritis.
APOL1 Modulates Renin-Angiotensin System.
Biomolecules
December 2024
Department of Medicine and Feinstein Institute for Medical Research, Zucker School of Medicine, Hempstead, NY 11549, USA.
Patients carrying APOL1 risk alleles (G1 and G2) have a higher risk of developing Focal Segmental Glomerulosclerosis (FSGS); we hypothesized that escalated levels of miR193a contribute to kidney injury by activating renin-angiotensin system (RAS) in the APOL1 milieus. Differentiated podocytes (DPDs) stably expressing vector (V/DPD), G0 (G0/DPDs), G1 (G1/DPDs), and G2 (G2/DPDs) were evaluated for renin, Vitamin D receptor (VDR), and podocyte molecular markers (PDMMs, including WT1, Podocalyxin, Nephrin, and Cluster of Differentiation [CD]2 associated protein [AP]). G0/DPDs displayed attenuated renin but an enhanced expression of VDR and Wilms Tumor [WT]1, including other PDMMs; in contrast, G1/DPDs and G2/DPDs exhibited enhanced expression of renin but decreased expression of VDR and WT1, as well as other PDMMs (at both the protein and mRNA levels).

A rare complication is posterior reversible encephalopathy syndrome (PRES), characterized by subcortical vasogenic cerebral edema associated with variable neurological symptoms. The development of autoimmune hemolytic anemia is an atypical clinical presentation.
