Although C1q nephropathy (C1qN) was introduced three decades ago, the clinical significance and renal outcomes of C1qN remain unclear. This study aimed to evaluate the clinical characteristics of C1qN, including renal outcomes, by performing a matched comparison within a multicenter cohort. We enrolled 6,413 adult patients who underwent kidney biopsy between January 2000 and January 2018 at three tertiary hospitals in Korea. Read More

Focal segmental glomerulosclerosis (FSGS) is defined by focal (involving few glomeruli) and segmental sclerosis of the glomerular tuft that manifests with nephrotic syndrome. Mutations in genes involved in the maintenance of structure and function of podocytes have been found in a minority of these patients. A family with adult-onset autosomal dominant FSGS was recently found to carry a new germline missense heterozygous mutation (p. Read More

Background: Observational studies show that African American (AA) dialysis patients have longer survival than European Americans. We hypothesized that apolipoprotein L1 (APOL1) genetic variation, associated with nephropathy in AAs, contributes to the survival advantage in AA dialysis patients.

Methods: We examined the association between race and mortality among 37,097 adult dialysis patients, including 54% AAs and 46% European Americans from a large dialysis organization (entry period from July 2001 to June 2006, follow-up through June 2007), within each cause of end-stage renal disease (ESRD) category associated with APOL1 renal risk variants using Cox proportional hazard models.

The epidemiological landscape of nephrotic syndrome (NS) in South Africa has changed drastically in the New Millennium. Although the pattern of disease in the 3 main non-Black racial groups (White, Indian, and Mixed race) mirror that seen in Western countries, Black African children show a pattern of disease that is at variance with these 3 racial groups. The incidence of infectious diseases, particularly hepatitis B virus associated nephropathy has sharply declined to being almost extinct in Black children in the New Millennium whereas HIV-related nephropathy surfaced.

Focal segmental glomerulosclerosis (FSGS) is the most common cause of adult-onset nephrotic syndrome, but its pathophysiology is poorly understood. The question as to why only a subset of patients responds to treatment in unanswered. In the past few years, change of podocytic phenotype from stationary type in health to migratory type in disease has been described, of which loss of subpodocytic space is a surrogate marker.

Apolipoprotein L1 (APOL1) risk variants are strongly associated with sporadic focal segmental glomerulosclerosis in populations with African ancestry. We determined the frequency of G1/G2 variants in patients with steroid-resistant nephrotic syndrome/focal segmental glomerulosclerosis with African or French West Indies origin in France and its relationships with other steroid-resistant nephrotic syndrome genes. In a cohort of 152 patients (139 families), the APOL1 risk variants were genotyped: the two risk allele (high risk) genotype was found in 43. Read More

Background: Patients with frequently relapsing (FR), steroid-dependent (SD) and steroid-resistant (SR) nephrotic syndrome are a therapeutic challenge with limited treatment options. Here, we retrospectively analyze the efficacy and safety of rituximab-induced continuous B-cell depletion in these populations.

Nephrotic syndrome (NS) is one of the most challenging conditions to manage and treat, partly because we lack a specific molecular understanding of its pathogenesis and progression. This limits our ability to provide targeted therapy or precise prognostications. Fortunately, genomic discovery in NS and its translation to genomic-informed medicine is allowing us to improve our understanding of the molecular anatomy of NS and our ability to care for patients with NS.

Background: Previously we found that kidney tissue and urinary exosomes from patients of diabetic kidney disease showed high levels of ceruloplasmin (CP). Because CP is an acute-phase protein of kidney origin, it could be an early marker of many other kidney diseases. To investigate this hypothesis, we first measured urine exosomal and kidney expression of CP in non-diabetic chronic kidney disease (CKD) patients (membranous nephropathy, focal segmental glomerulosclerosis, lupus nephritis and IgA nephropathy) followed by a longitudinal study in rat passive Heymann nephritis (PHN), a model of human membranous nephropathy.

Background: The aims were to compare the cardiovascular disease (CVD) risk among children with chronic kidney disease (CKD) secondary to focal segmental glomerulosclerosis (FSGS) with the CVD risk of children with CKD due to other diagnoses.

Methods: Casual blood pressure (BP), ambulatory blood pressure monitoring (APBM), echocardiogram, lipids, carotid intima medial thickness (cIMT), and uric acid obtained from participants in the Chronic Kidney Disease in Children (CKiD) cohort were analyzed longitudinally.

Both disease entities resemble each other and can sometimes only be discriminated on the basis of their clinical courses. MCD and FSGS display two classical examples that share a common pathophysiology in which the glomerular podocyte and the cytoskeleton of its foot processes play important roles. Read More

In older adults, the most common kidney biopsy diagnoses include pauci-immune crescentic glomerulonephritis, membranous nephropathy, and focal segmental glomerulosclerosis. Recently, investigators described a small series of older patients (aged 66-80 years) with acute kidney injury and a kidney biopsy demonstrating tubular basement membrane (TBM) immune deposits of polytypic immunoglobulin G (IgG) and C3, acute tubular injury, and tubulointerstitial inflammation. They identified a circulating antibody against kidney tubular low-density lipoprotein (LDL) receptor-related protein 2 (LRP2; also known as megalin) in patients' sera and colocalization of LRP2 with IgG in TBM deposits.

Because of its rarity, renal presentation and outcomes of idiopathic nephrotic syndrome (INS; minimal changes disease or focal and segmental glomerulosclerosis) has poorly been described in elderly patients, precluding an individualized therapy procedure. Whether immunosuppressive regimens formerly designed in children and young adults are safe and efficient in elderly remains elusive. In a large multicentric retrospective study that included 116 patients with INS and onset ≥ 60 years of age, we showed that cumulative incidence of renal response was 95% after frontline therapy, with an age-dependent median time-to-response (60 days before 70 years of age at the onset vs. Read More

Background/aims: Calcineurin inhibitors (CNIs) such as cyclosporine A (CsA) and tacrolimus are immunosuppressants that are frequently used as "key drugs" in the fields of transplantation, steroid resistance, refractory nephrotic syndrome, and autoimmune disease. However, long-term CNI use causes nephrotoxicity, the features of which are arteriolar hyalinosis, tubular atrophy, striped interstitial fibrosis, and focal segmental glomerulosclerosis (FSGS). We investigated whether FSGS in CNI-induced nephrotoxicity is associated with CD44-positive glomerular parietal epithelial cells (PECs), which play a significant role in experimental and human FSGS pathogenesis.
