Despite treatment with immunosuppressive or clone-targeted chemotherapy, patients with proliferative glomerulonephritis with monoclonal immunoglobulin deposit (PGNMID) frequently progress into end-stage kidney failure, and early recurrence of PGNMID after kidney transplantation is common. The standard management of PGNMID has been unclear, currently based on data from small cohorts, which requires a need for additional therapeutic regimens in this disease. A human IgG monoclonal antibody that targets CD38 (daratumumab) was recently identified as a potential therapeutic option for treating PGNMID.

Article Synopsis
  • Autosomal dominant polycystic kidney disease (ADPKD) primarily results from diverse genetic variants in the PKD1 and PKD2 genes, making diagnosis complicated due to genetic similarities and high GC content in PKD1.
  • The "comprehensive analysis of ADPKD" (CAPKD) method utilizes a single-tube multiplex long-range-PCR and long-read sequencing, enhancing the genetic analysis in a study involving 170 patients compared to other methods like next-generation sequencing (NGS).
  • CAPKD significantly improved the detection of variants, identifying 160 out of 170 patients with PKD1 and PKD2 variants, thus raising the diagnostic accuracy for pathogenic variants and allowing for better characterization of complex genetic configurations.

Traditional Chinese medicine (TCM) is an essential part of the Chinese medical system and is recognized by the World Health Organization as an important alternative medicine. As an important part of TCM, TCM diagnosis is a method to understand a patient's illness, analyze its state, and identify syndromes. In the long-term clinical diagnosis practice of TCM, four fundamental and effective diagnostic methods of inspection, auscultation-olfaction, inquiry, and palpation (IAOIP) have been formed.

Article Synopsis
  • This study investigates methods to predict rapid progressors (RPs) in patients with autosomal dominant polycystic kidney disease (ADPKD) in the Asia-Pacific region, involving five hospitals from different countries.
  • Results showed that, out of 768 patients, 426 were identified as RPs, with significant occurrences of kidney-related complications and a higher rate of progression to end-stage kidney disease (ESKD) compared to slow progressors (SPs).
  • The strongest predictor of RP was historical decline in estimated glomerular filtration rate (eGFR), suggesting the need for varied assessment strategies in clinical practice for better identification of RPs among ADPKD patients.

Autosomal-dominant polycystic kidney disease (ADPKD) is characterized by uncontrolled renal cyst formation, and few treatment options are available. There are many parallels between ADPKD and clear-cell renal cell carcinoma (ccRCC); however, few studies have addressed the mechanisms linking them. In this study, we aimed to investigate their convergences and divergences based on bioinformatics and explore the potential of compounds commonly used in cancer research to be repurposed for ADPKD.

  • Bilateral carotid artery occlusion (CAO) is a rare condition that complicates blood flow compensation, particularly involving the circle of Willis (CoW), which plays a key role in providing collateral circulation.
  • A study of 30 patients revealed varying types of CoW structures, with 60% having a partially complete type and identifying multiple collateral pathways such as the anterior communicating artery and leptomeningeal anastomoses.
  • Findings indicate that while collateral circulation is present in most cases, a significant percentage of patients demonstrate incomplete CoW structures, highlighting the complexity of blood flow compensation in bilateral CAO.

Polycystic kidney disease (PKD) is a group of hereditary kidney diseases caused by genetic mutations. Autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD) are the two main forms of PKD. The pathological features of PKD include progressive enlargement of renal cysts and destruction of kidney structure, which may eventually lead to end-stage renal disease (ESRD).

Positive transcription elongation factor b (P-TEFb) functions as a central regulator of transcription elongation. Activation of P-TEFb occurs through its dissociation from the transcriptionally inactive P-TEFb/HEXIM1/7SK snRNP complex. However, the mechanisms of signal-regulated P-TEFb activation and its roles in human diseases remain largely unknown.

Autosomal dominant polycystic kidney disease (ADPKD) is considered as a tumor-like disease because there are many biological similarities between ADPKD and cancer. However, the commonalities between them are provocative, particularly under the conditions of recent clinical studies. In this paper, we review clinical studies about the association between cancer and ADPKD, and compare the biological characteristics between them, with focusing on cell proliferation, differentiation, migration, apoptosis, and polarity.

Article Synopsis
  • Polarity complexes like PAR, CRB, and SCRIB are crucial for maintaining cell structure, and their dysfunction can lead to cystic kidney diseases, such as autosomal-dominant polycystic kidney disease (ADPKD).
  • The study found that Scribble, part of the SCRIB complex, is less active in ADPKD models, and its overexpression can help prevent cyst formation in zebrafish and cell lines.
  • Additionally, the research indicates a link between Scribble and the Hippo signaling pathway, showing that Scribble affects cyst formation by regulating the location of Yes-associated protein (YAP) within the cell.

Article Synopsis
  • Angiotensin II (Ang II) is recognized as a significant contributor to renal fibrosis, while Krüppel-like factor 15 (KLF15) serves as an important negative regulator in this process.
  • The study used mouse models to analyze KLF15 expression in response to Ang II, finding that Ang II reduces KLF15 levels and contributes to fibrosis, an effect that can be mitigated by losartan, a medication that blocks Ang II receptors.
  • Experiments in cultured rat renal fibroblasts showed that Ang II not only decreased KLF15 levels but also increased profibrotic factors, suggesting that KLF15 might inhibit the promotion of fibrotic processes by directly interfering with the CTGF promoter.

Anti-glomerular basement membrane (GBM) disease is characterized by circulating anti-GBM antibodies and deposition of these antibodies in the renal GBM. Renal involvement in anti-GBM is more severe when compared with other types of immune-mediated glomerulonephritis, and the majority of patients manifest progressive renal failure, leading to end-stage renal disease. In a limited number of cases, anti-GBM disease has been shown to be accompanied with other immune-mediated glomerulonephritis.

Pd/Y multilayer mirrors operating in the soft X-ray region are characterized by a high theoretical reflectance, reaching 65% at normal incidence in the 8-12 nm wavelength range. However, a severe intermixing of neighboring Pd and Y layers results in an almost total disappearance of the interfaces inside the multilayer structures fabricated by direct current magnetron sputtering and thus a dramatic reflectivity decrease. Based on grazing incidence X-ray reflectometry and X-ray photoelectron spectroscopy, we demonstrate that the stability of the interfaces in Pd/Y multilayer structures can be essentially improved by adding a small amount of nitrogen (4-8%) to the working gas (Ar).
