Considerable shortages in the supply of available organs continue to plague the field of solid organ transplantation. Despite changes in allocation, as well as the utilization of extended criteria and living donors, the number of patients waiting for organs continues to grow at an alarming pace. Xenotransplantation, cross-species solid organ transplantation, offers one potential solution to this dilemma. Previous extensive research dedicated to this field has allowed for resolution of xenograft failure due to acute rejection, leaving new areas of unresolved challenges as barriers to success in large animal models...

BACKGROUND: Congenital sphingosine-1-phosphate (S1P) lyase deficiency due to biallelic mutations in SGPL1 gene has recently been described in association with primary adrenal insufficiency and steroid-resistant nephrotic syndrome. S1P lyase, on the other hand, is therapeutically inhibited by fingolimod which is an oral drug for relapsing multiple sclerosis (MS). Effects of this treatment on adrenal function has not yet been evaluated. We aimed to test adrenal function of MS patients receiving long-term fingolimod treatment...

Minimal change disease (MCD) is one of the most common causes of nephrotic syndrome in children, leading to heavy proteinuria and edema. However, it is not as common in adults. Adult-onset minimal change disease with IgA nephropathy is rare. The initial presentation of heavy proteinuria and edema with effacement of podocytes on electron microscopy (EM) should lead the physician to suspect minimal change disease regardless of age. We present a 44-year-old male patient with a history of hepatitis C virus (HCV) who presented with sudden onset of lower extremity edema and 6...

Idiopathic membranous nephropathy (IMN) is a major cause of nephrotic syndrome. No biomarker to predict the long-term prognosis of IMN is currently available. Growth differentiation factor-15 (GDF-15) is a member of the transforming growth factor- β superfamily and has been associated with chronic inflammatory disease. It has the potential to be a useful prognostic marker in patients with renal diseases, such as diabetic nephropathy and IgA nephropathy. This study examined whether GDF-15 is associated with the clinical parameters in IMN and showed that GDF-15 can predict IMN disease progression...

With normal aging, there are increased numbers of globally sclerotic glomeruli. Global glomerulosclerosis is also a feature of chronic kidney disease. In this issue, Hommos and colleagues provide data on the fraction of globally sclerotic glomeruli in healthy kidney donor biopsies. This provides reference for evaluation of whether isolated global glomerulosclerosis is evidence of pathology.

BACKGROUND: The lack of high-quality clinical evidences hindered broad consensus on optimal therapies for primary nephrotic syndromes. The aim of the present study was to compare prevalence of immunosuppressive drug use in patients with primary nephrotic syndrome across 6 regions in Japan. METHODS: Between 2009 and 2010, 380 patients with primary nephrotic syndrome in 56 hospitals were enrolled in a prospective cohort study [Japan Nephrotic Syndrome Cohort Study (JNSCS)], including 141, 151, and 38 adult patients with minimal change disease (MCD), membranous nephropathy (MN), and focal segmental glomerulosclerosis (FSGS), respectively...

The glomerular basement membrane (GBM) is an important component of the kidney's glomerular filtration barrier. Like all basement membranes, the GBM contains type IV collagen, laminin, nidogen, and heparan sulfate proteoglycan. It is flanked by the podocytes and glomerular endothelial cells that both synthesize it and adhere to it. Mutations that affect the GBM's collagen α3α4α5(IV) components cause Alport syndrome (kidney disease with variable ear and eye defects) and its variants, including thin basement membrane nephropathy...

Rare renal diseases (RRD) are an important category of rare disease (RD) as they can do great damage to the patients, families and society. The patient may undergo years even decades of numerous investigations including invasive procedures and yet not have definitive and precise diagnose and therefore, no opportunity for appropriate treatment. The great progress in molecular genetic techniques characterized many Mendelian diseases on molecular level. This gave the possibility for appropriate prevention and treatment interventions, genetic counseling and prenatal diagnosis...

Patients with diabetic nephropathy develop nephrotic syndrome, and may show limited response to conventional therapy. They often require earlier initiation of renal replacement therapy because they become refractory to diuretics, and experience excessive fluid retention. We aimed to investigate the efficacy of tolvaptan, an oral arginine vasopressin type 2 receptor antagonist, in a case series of 14 severe diabetic renal failure patients who were severely refractory to maximal doses of furosemide and had excessive fluid retention despite preserved cardiac function and residual renal function...

BACKGROUND: Congenital nephrotic syndrome (CNS) is primarily a monogenetic disease, with the majority of cases due to changes in five different genes: the nephrin (NPHS1), podocin (NPHS2), Wilms tumor 1 (WT1), laminin ß2 (LAMB2), and phospholipase C epsilon 1 (PLCE1, NPHS3) gene. Usually CNS is not responsive to immunosuppressive therapy, but treatment with ACE inhibitors, AT1 receptor blockade and/or indomethacin can reduce proteinuria. If the disease progresses to end-stage renal disease, kidney transplantation is the therapy of choice...

Secondary amyloidosis Amyloid A (AA) is an infrequent but a severe complication of Crohn's disease (CD). This complication results from the activity of the underlying inflammation disease to form amyloid fibril deposits in tissues. We present a case of a 34-year-old female patient with CD treated by azathioprine with inactive disease for three years and who developed a nephrotic syndrome secondary to AA amyloidosis. The treatment by infliximab for one year leads to a complete remission of the nephrotic syndrome...

Paraneoplastic glomerulopathy (PG) includes a group of glomerular lesions that are not directly related to tumor burden, invasion, or metastasis, but induced by products from tumor cells such as hormones, growth factors, cytokines, and tumor antigens. PG was first described by Galloway in 1922, in which nephrotic syndrome (NS) secondary to Hodgkin's lymphoma was reported. They can present before, at the time of diagnosis, during remission, or at relapse of the hematological malignancies. We present three cases of paraneoplastic NS associated with hematological malignancies...

Abdominal symptoms are common in patients with lupus nephritis and are often attributed to drugs or uremia per se. Lupus mesenteric vasculitis (LMV) or lupus enteritis is a rare entity reported in patients with active systemic lupus erythematosus. It usually occurs in patients with a long-standing history of lupus with high disease activity. Usually, small bowel is predominantly affected. The stomach and rectum are spared in view of significant collateral circulation. Here, we describe an 18-year-old boy who presented with nephrotic syndrome without any extrarenal features of lupus...

Secondary renal amyloidosis (RA) is the most common type of renal involvement in ankylosing spondylitis (AS). We assessed the epidemiologic and clinico-biological profile of AS patients with RA, to analyze treatment modalities and prognostic aspects, and to determine predictive factors of RA during AS. This was a retrospective study including 13 cases of RA among 212 cases who presented with AS, during the period from 1978 to 2006. The median age of the patients at the time of diagnosing AS was 47 years (range: 19-67)...
