We present a case of nephrotic syndrome secondary to a membranous glomerulonephritis (MG), in a nonsmoking female with a solitary pulmonary nodule, which did not show growth during 2 years of followup. A biopsy by videothoracoscopy showed a granulomatous non-neoplastic process with giant multinucleated cells. The appearance of a nephrotic syndrome and its interpretation as paraneoplastic revealed the existence of a primary pulmonary lymphoepithelioma-like carcinoma (LELC), a very rare pulmonary tumor. After resection of tumor there was a complete recovery from the nephrotic syndrome. This case highlights how the investigation of paraneoplastic syndromes can help in the early diagnosis of some malignancies.

Reports of glomerulonephritis associated with lymphoproliferative disorders are common, but reports of minimal change disease (MCD) accompanying non-Hodgkin's lymphoma are rare. Here, we present a case of a 45-year-old woman diagnosed with primary Waldenström's macroglobulinemia (WM) during MCD treatment. Her kidney biopsy revealed endothelial cell injury in parts of the MCD.

Background: Idiopathic nephrotic syndrome (NS) is the most prevalent glomerular disease in children. Heat shock protein 70 (HSP70) is synthesized in response to diverse stress factors like infections and oxidative stress. We aimed to evaluate serum and urine levels of HSP70 in children with steroid-sensitive nephrotic syndrome (SSNS) and to assess changes in HSP70 levels with prednisolone treatment.

Adult nephrotic syndrome is primarily caused by membranous nephropathy (MN), with idiopathic membranous nephropathy (IMN) being a prominent subtype. The onset of phospholipase A2 receptor (PLA2R1)-associated IMN is critically linked to M-type PLA2R1 exposure, yet the mechanism underlying glomerular injury remains unclear. In this study, membranous nephropathy datasets (GSE115857, GSE200828) were retrieved from GEO.

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.

Nephrotic syndrome (NS) occurs in 5-15% of patients with IgA nephropathy (IgAN), resulting in poorer long-term outcomes compared to those without NS. Clinical features and renal prognosis for patients with both NS and IgAN across different kidney pathologies have not been fully elucidated. This study included patients with primary IgAN through renal biopsy at the First Affiliated Hospital of Sun Yat-sen University from January 2001 to November 2021 presenting with NS.
