BACKGROUND: The most common cause of nephrotic syndrome (NS) is idiopathic nephrotic syndrome (INS), also called nephrosis. Although most patients respond to steroid therapy, there is unequal response to treatment suggesting the involvement of genetic factors. The current study was conducted to evaluate the influence of two single nucleotide polymorphisms (SNPs) in ABCB1 (C3435T and C1236T) on the steroid treatment response in INS children. MATERIALS AND METHODS: Genotyping of ABCB1 C3435T and C1236T polymorphisms by real time PCR were conducted on 120 INS children, 80 steroid sensitive (SS) and 40 steroid resistant (SR)...

Shenkangling plays a role of Yishenhuoxue effect for the treatment of children with nephrotic syndrome. The aim of this study was to investigate the effects of Shenkangling intervention on the mitogen-activated protein kinase (MAPK) pathway in rats with Adriamycin-induced nephropathy (AN) and its underlying mechanism of action. Nephrosis was induced in healthy Sprague-Dawley rats by doxorubicin and the rats were untreated or treated with prednisone, simvastatin, Shenkangling, or a combination thereof. Using real-time PCR, the mRNA expression levels of Chemokine (C-X-C motif) ligand 16 (CXCL16), A Disintegrin and metalloproteinase domain-containing protein 10 (ADAM10), and ADAM17 in the renal tissues of these rats were found to be decreased by the various treatments compared to those in the untreated doxorubicin-induced nephrosis rats...

Systemic lupus erythematosus (SLE), a disorder of the immune system, is potentially curable by allogeneic bone marrow transplantation (alloBMT). Until recently, alloBMT was limited by donor availability and toxicity. Reduced intensity conditioning (RIC) combined with post-transplantation cyclophosphamide (PTCy) has improved the availability and safety of alloBMT permitting its exploration in severe-refractory autoimmune illnesses. We report the six-year follow-up of a young female whose refractory SLE-associated nephrosis resolved after RIC alloBMT with PTCy...

In brain-dead donor resuscitation, hydroxyethyl starch (HES) use has been associated with presence of osmotic-nephrosis-like lesions in kidney transplant recipients. Our aim was to determine whether the presence of HES in protocol renal graft biopsies at three months (M3) after transplantation is associated with renal graft quality. According to the HES administered to the donor during the procurement procedure, two groups of patients were defined according graft exposition to HES: HES group, (N = 20) and control group (N = 6)...

BACKGROUND: Aberrant glomerular polyanionic charge of glycosaminoglycans (GAGs) and sialic acid expression has been observed in proteinuric human and experimental glomerular diseases. Angiotensin-converting enzyme inhibitors (ACEI) lower proteinuria and amend renal function deterioration via hemodynamic mechanisms. We tested the hypothesis that ACEI modulate proteinuria additionally by modifying glomerular GAGs. METHODS: In this study, we explored the effects of the ACEI enalapril on proteinuria and GAG synthesis in puromycin aminonucleoside (PAN)-treated rats...

Serum albumin concentration (CP) is a remarkably strong prognostic indicator of morbidity and mortality in both sick and seemingly healthy subjects. Surprisingly, the specifics of the pathophysiology underlying the relationship between CP and ill-health are poorly understood. This review provides a summary that is not previously available in the literature, concerning how synthesis, catabolism, and renal and gastrointestinal clearance of albumin interact to bring about albumin homeostasis, with a focus on the clinical factors that influence this homeostasis...

Health effects following low doses of ionizing radiation are uncertain. Military veterans at the Nevada test site (NTS) during the SMOKY atmospheric nuclear weapons test in 1957 were reported to be at increased risk for leukemia in 1979, but this increase was not evaluated with respect to radiation dose. The SMOKY test was one of 30 tests in 1957 within the PLUMBBOB test series. These early studies led to public laws where atomic veterans could qualify for compensation for presumptive radiogenic diseases. A retrospective cohort study was conducted of 12219 veterans at the PLUMBBOB test series, including 3020 at the SMOKY nuclear test...

Bile cast nephropathy is a tubulo-interstitial nephropathy. Its diagnosis may be under-estimated. It develops in patients who have cholestatic jaundice, with high bilirubinemia. Bile salts are freely filtered through glomerulus. Under certain circumstances, it forms casts into the tubule and cause an acute tubular necrosis. The diagnosis evidence is histologic, but fulfilment of renal biopsy is often made difficult, because of the hemostatic abnormalities that patients with hepatocellular injury develop. The treatment is supportive and etiological...

The RNA-guided endonuclease clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein 9 (Cas9) derived from CRISPR systems is a simple and efficient genome-editing technology applied to various cell types and organisms. So far, the extensive approach to detect the cleavage activity of customized Cas9/guide RNA (gRNA) is T7 endonuclease I (T7EI) assay, which is time and labor consuming. In this study, we developed a visualized fluorescent reporter system to detect the specificity and cleavage activity of gRNA...

Fanconi-Bickel Syndrome (FBS) is an autosomal recessive disorder of the carbohydrate metabolism, which has been reported in human and some animals (OMIA 000366-9913). In Fleckvieh cattle it is caused by mutations in SLC2A2, a gene encoding for glucose transporter protein 2 (GLUT2), which is primarily expressed in liver, kidney, pancreas and intestines. The causal mutation resides in a previously reported Fleckvieh Haplotype 2 (FH-2). FH-2 homozygous individuals are rare, but due to widespread use of heterozygous bulls in artificial insemination, heterozygous animals are likely to be present in a larger number in the cattle population...

In Japan, Dr. Michiaki Takahashi (1928-2013) successfully developed the first live attenuated varicella vaccine in the world. The virus used for this vaccine was varicella-zoster virus isolated from the vesicular fluid of a child with typical varicella and it was named the Oka strain after the family name of the child. In 1974, a patient with nephrosis developed varicella in the Pediatric Ward, and uninfected pediatric patients received varicella vaccine immediately. As a result, there were no cases of varicella in the other children and all of the vaccinated children acquired immunity to the disease...

The tight junction (TJ) has a key role in regulating paracellular permeability to water and solutes in the kidney. However, the functional role of the TJ in the glomerular podocyte is unclear. In diabetic nephropathy, the gene expression of claudins, in particular claudin-1, is markedly upregulated in the podocyte, accompanied by a tighter filtration slit and the appearance of TJ-like structures between the foot processes. However, there is no definitive evidence to show slit diaphragm (SD) to TJ transition in vivo Here, we report the generation of a claudin-1 transgenic mouse model with doxycycline-inducible transgene expression specifically in the glomerular podocyte...

Kidney injury in the context of cholestatic liver dysfunction is not uncommon; this has been historically referred to as cholemic nephrosis implying a direct deleterious renal effect of cholemia. However, scepticism about the exact role that bile and its constituents play in this injury has led to the disappearance of the term. We describe a case of severe AKI due to bile nephropathy with bile casts in flucloxacillin-induced liver dysfunction. We also discuss the recent literature reviving the concept of bile nephropathy...
