Intravesical Bacillus Camlette-Guérin (BCG) is the treatment of choice for non-muscle invasive bladder cancer, and has been used successfully for over 40 years. A rare and potentially fatal complication of intravesical BCG therapy is BCG-induced sepsis. We report a rare case in which a patient with end-stage renal disease secondary to chronic granulomatous interstitial nephritis underwent remote, pre-transplant intravesical BCG treatment for high-grade non-invasive papillary bladder carcinoma. The patient subsequently received a deceased donor kidney transplant 5 years after BCG therapy, with thymoglobulin induction therapy and standard triple maintenance immunosuppression...

INTRODUCTION: In contrast to organ transplantation, few studies correlate the monitoring of pp65 antigenemia with a diagnosis of cytomegalovirus (CMV) in patients with systemic lupus erythematosus (SLE). OBJECTIVE: To highlight the importance of CMV outside transplantation, we monitored pp65 antigenemia in a series of SLE patients. METHODS: From March 2015 to March 2016, SLE patients presenting kidney involvement, fever, and an unclear infection at hospital admission were monitored through pp65 antigenemia...

Systemic lupus erythematosus (SLE) is an autoimmune chronic inflammatory disease that affects multiple organs and tissues. Lupus nephritis (LN) is a serious complication of SLE, which occurs at a high rate. Conventional treatment strategies of LN have been widely accepted by two concepts such as induction therapy and maintenance therapy. In LN induction therapy until recently, cyclophosphamide in combination with prednisone (PSL) has been the standard method of treatment for proliferative forms of LN. In the latest review, the combination of mycophenolate mofetil (MMF) is also considered a standard treatment option...

BACKGROUND: The clinical outcomes after kidney transplantation (KT) according to the types of glomerulonephritis (GN) as the cause of end-stage renal disease (ESRD) are various, but there are not many studies on this. METHODS: Among 1,253 patients who had KT between November 1982 and January 2017, 183 recipients with biopsy-proven GN as the primary cause of ESRD were enrolled. We analyzed the incidence of recurrent GN and the factors associated with recurrence and graft and patient survivals...

The human microbiome is important for health and plays a role in essential metabolic functions and protection from certain pathogens. Conversely, dysbiosis of the microbiome is seen in the context of various diseases. Recent studies have highlighted that a complex microbial community containing hundreds of bacteria colonizes the healthy urinary tract, but little is known about the human urinary viruses in health and disease. To evaluate the human urinary virome in the context of kidney transplantation (tx), variations in the composition of the urinary virome were evaluated in urine samples from normal healthy volunteers as well as patients with kidney disease after they had undergone kidney tx...

Renal DNase I is lost in advanced stages of lupus nephritis. Here, we determined if loss of renal DNase I reflects a concurrent loss of urinary DNase I, and whether absence of urinary DNase I predicts disease progression. Mouse and human DNase I protein and DNase I endonuclease activity levels were determined by western blot, gel, and radial activity assays at different stages of the murine and human forms of the disease. Cellular localization of DNase I was analyzed by immunohistochemistry, immunofluorescence, confocal microscopy, and immunoelectron microscopy...

IgG4-related disease is a relatively newly described entity that can affect nearly any organ, including the kidneys, where it usually manifests as tubulointerstitial nephritis (IgG4-TIN). The diagnosis can be suggested by characteristic histological features, including an inflammatory infiltrate with increased IgG4-positive plasma cells associated with "storiform" fibrosis. Serum IgG4 is usually elevated. In the native kidney and other organs, there is typically a brisk response to treatment with immunosuppression...

CRISPR is a nuclease guidance system that enables rapid and efficient gene editing of specific DNA sequences within genomes. We review applications of CRISPR for the study and treatment of kidney disease. CRISPR enables functional experiments in cell lines and model organisms to validate candidate genes arising from genetic studies. CRISPR has furthermore been used to establish the first models of genetic disease in human kidney organoids derived from pluripotent stem cells. These gene-edited organoids are providing new insight into the cellular mechanisms of polycystic kidney disease and nephrotic syndrome...

Collapsing focal segmental glomerulosclerosis (FSGS) is a variant of FSGS and is associated with severe nephrotic syndrome and acute kidney injury and can occur after kidney transplantation. The exact mechanism of collapsing FSGS after kidney transplantation is unknown, but potential causes include autoimmune diseases, certain malignancies, bisphosphonates, m-TOR inhibitors, interferon-alpha, HIV infection, and other viruses. We describe a case of de novo Cytomegalovirus (CMV)-associated collapsing FSGS in a kidney transplant recipient with a UL97 phosphotransferase mutation that was successfully treated with intravenous ganciclovir, intravenous immunoglobulin, and steroids...

The IL-17 cytokine family and the cognate receptors thereof have a unique role in organ-specific autoimmunity. Most studies have focused on the founding member of the IL-17 family, IL-17A, as the central mediator of diseases. Indeed, although pathogenic functions have been ascribed to IL-17A and IL-17F in the context of immune-mediated glomerular diseases, the specific functions of the other IL-17 family members in immunity and inflammatory kidney diseases is largely unknown. Here, we report that compared with healthy controls, patients with acute Anti-neutrophil cytoplasmatic antibody (ANCA)-associated crescentic glomerulonephritis (GN) had significantly elevated serum levels of IL-17C (but not IL-17A, F, or E)...

BACKGROUND: Systemic lupus erythematosus (SLE) is a severe autoimmune disease that involves multiple organ systems. Lupus nephritis (LN) is a complication of SLE and is associated with poor survival and high morbidity. Many genomic studies have been performed worldwide, and several histocompatibility leukocyte antigen (HLA) loci are linked to lupus susceptibility. OBJECTIVE: The present study evaluated the association of HLA alleles in a lupus patient population, LN group and control group...

Mammalian or mechanistic target of rapamycin (mTOR) is a serine-threonine kinase that plays essential roles in cell growth, proliferation, metabolism, and survival. Increased activation of the mTOR pathway is observed in patients and animal models of renal transplant rejection, autosomal dominant polycystic kidney disease, renal cell carcinoma, diabetic nephropathy, lupus nephritis, and angiomyolipoma. Agents that inhibit mTOR, such as sirolimus and everolimus, are incorporated in immunosuppressive regimens to prevent renal allograft rejection and are often used to facilitate calcineurin inhibitor minimization or to reduce the incidence of tumor recurrence...

Renal transplantation remains the best option for patients suffering from end stage renal disease (ESRD). Given the worldwide shortage of organs and growing population of patients with ESRD, those waitlisted for a transplant is ever expanding. Contemporary crossmatch methods and human leukocyte antigen (HLA) typing play a pivotal role in improving organ allocation and afford better matches to recipients. Understanding crossmatch as well as HLA typing for renal transplantation and applying it in clinical practice is the key step to achieve a successful outcome...

Background: Despite being the leading cause of graft failure, there is a lack of published data about the rates of rejection in kidney transplant patients with glomerulonephritis as the cause of end-stage renal disease. Methods: We examined all consecutive adult (>18 years) renal transplant recipients with biopsy-proven native renal glomerular disease who underwent kidney transplant between 1994 and 2013. Glomerulonephritis groups included were IgA nephropathy (IgAN) (N = 306), focal segmental glomerulosclerosis (FSGS) (N = 298), membranous nephropathy (MN) (N = 81), and lupus nephritis (LN) (N = 177)...

Hematopoietic cell transplantation (HCT) is an increasingly used treatment for hematologic malignancies as well as for nonmalignant diseases. Kidney impairment remains an important early and late post-transplantation complication. Although numerous histopathological changes have been reported, the pathophysiology remains incompletely understood. Furthermore, correlations between clinical findings and morphological changes have not been well studied. Between 2000 and 2016, 17 recipients of allogeneic (n = 12) or autologous (n = 5) HCT underwent kidney biopsy for either proteinuria or deterioration of kidney function at our center...

With the recent introduction of more potent modern immunosuppressive regimens in solid-organ transplant, new types of viral infections such as adenovirus are emerging as a potential cause for graft dysfunction and loss. We report a case of 41-year-old male patient with end-stage renal disease from recurrent kidney stones who underwent kidney transplant from a deceased 12-year-old female donor. He developed adenoviral infection with acute cystitis, microscopic hematuria, and necrotizing interstitial nephritis associated with graft dysfunction within the first month of the postoperative period...

BACKGROUND: Symptoms and signs of acute tubulointerstitial nephritis (ATIN) are nonspecific; therefore, renal biopsy is often necessary to clarify the diagnosis. The aim of this study was to evaluate the use of 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy in the diagnosis and follow-up of ATIN. METHODS: We retrospectively reviewed the charts of five patients (nine renal units) with a median age of 14 years who underwent DMSA scan after a clinical and/or biopsy-proven diagnosis of ATIN...
