A significant proportion of individuals with systemic lupus erythematosus (SLE) will have clinical or laboratory evidence of renal involvement at some point in the course of their disease. Lupus nephritis (LN) is one of the more important systemic manifestations of SLE and although progression to end-stage renal disease (ESRD) is not usually the norm, a significant minority of patients will do so, some in a rather dramatic fashion. It is in such instances that LN constitutes a true nephrologic emergency. Gratifyingly, it is rarely a silent emergency and heightened awareness amongst clinicians about its unpredictable course should lead to earlier recognition and intervention...

Immunoglobulin A nephropathy or Berger's disease is the most common type of primary glomerulonephritis, which is characterized by IgA1-containing immune-deposits in the glomerular mesangium. Microscopic haematuria and proteinuria are the most common presentations. Mesangial cell proliferation with IgA deposition is found on renal biopsy. Mechanims of the disease implicate at least four key molecules have been implicated in immune complex formation: galactose-deficient IgA1, autoantibodies anti-galactose-deficient-IgA1, soluble CD89 (Fc receptor for IgA) and the CD71 mesangial IgA receptor (transferrin receptor)...

BACKGROUND: Vancomycin is the first-line antibiotic for methicillin-resistant Staphylococcus aureus and coagulase-negative strains. The risk of vancomycin-induced acute kidney injury increases with plasma vancomycin levels. Vancomycin-induced acute kidney injury is histologically characterized by acute interstitial nephritis and/or acute tubular necrosis. However, only 12 biopsy-proven cases of vancomycin-induced acute kidney injury have been reported so far, as renal biopsy is rarely performed for such cases...

The most common renal disease associated with human immunodeficiency virus infection (HIV) is HIV-associated nephropathy (HIVAN), especially in the African American patient population. However, various patterns of glomerulonephritis (GN) are not uncommon, collectively accounting for nearly half of the renal biopsies performed in HIV patients. Most GNs that occur in HIV patients are immune complex mediated, often with concurrent infections such as hepatitis B or C. Fibrillary glomerulonephritis (FGN), a rare primary glomerular disease, has only been reported in 2 HIV patients, and both patients had concurrent hepatitis C (HCV) infection...

Although sudden sensorineural hearing loss (SSNHL) affects chronic kidney disease (CKD) patients more frequently than non-CKD patients, few reports have described SSNHL in dialysis patients. We aimed to review the characteristics of SSNHL in chronic dialysis patients and evaluate treatment responses to steroid therapy. We retrospectively reviewed the records of dialysis patients diagnosed with idiopathic SSNHL at Asan Medical Center between January 2000 and December 2014. Pure tone and speech audiometry analyzes were performed before and 2 weeks and 2 months after treatment onset to evaluate outcomes...

Epigenetics refers to heritable changes in gene expression patterns not caused by an altered nucleotide sequence, and includes non-coding RNAs and covalent modifications of DNA and histones. This review focuses on functional evidence for the involvement of DNA and histone epigenetic modifications in the pathogenesis of kidney disease and the potential therapeutic implications. There is evidence of activation of epigenetic regulatory mechanisms in acute kidney injury (AKI), chronic kidney disease (CKD) and the AKI-to-CKD transition of diverse aetiologies, including ischaemia-reperfusion injury, nephrotoxicity, ureteral obstruction, diabetes, glomerulonephritis and polycystic kidney disease...

In this review we discuss how sex steroids and prolactin affect regulation and responsiveness of B and T cells. Sex hormones exert profound effects on several physiological processes of non- reproductive tissues. In the immune system, several studies with experimental models for SLE have shown a noticeable pro-inflammatory role for ERα, contributing to disease development reflected in proteinuria and renal pathology. On the other hand, ERβ appears to have an anti- inflammatory and immunosuppressive effect...

INTRODUCTION: Hydralazine is an antihypertensive medication that has been associated with drug-induced lupus erythematosus (DIL) as well as ANCA-associated vasculitis (AAV). Although rare, early diagnosis is critical since drug cessation is the mainstay of therapy. This retrospective study aims to characterize the clinical, laboratory, and histopathologic features of this disease. METHODS: Once approval was obtained from the Institutional Review Board at the University of Iowa, all patients carrying a diagnosis of vasculitis (ICD9 code: 447...

Background: Glomerulonephritis (GN) consists of a group of kidney diseases that are categorized based on shared histopathological features. The current classifications for GN make it difficult to distinguish the individual variability in presentation, disease progression, and response to treatment. GN is a significant cause of end-stage renal disease (ESRD), and improved therapies are desperately needed because current immunosuppressive therapies sometimes lack efficacy and can lead to significant toxicities...

IgA nephropathy (IgAN) is the most common cause of primary glomerulonephritis worldwide. Up to 30% of cases develop the progressive form of the disease, eventually requiring renal replacement therapy. Diagnosis and risk stratification relies on an invasive kidney biopsy and management options are limited, with recurrence following renal transplantation being common. Thus the quest to understand the pathophysiology of IgAN has been one of great importance. MicroRNAs (miRs) are short nucleotides that suppress gene expression by hybridizing to the 3' untranslated region of messenger RNA (mRNAs), promoting mRNA degradation or disrupting translation...

Dengue is a significant health problem in many countries. In recent years, complications involving specific organ systems have been increasingly observed and appear to have important effects on overall dengue related morbidity and mortality. Renal involvement in dengue could potentially cause increased mortality and long term effects. We review the different renal manifestations associated with dengue virus infections and explore their potential underlying pathophysiological mechanisms. The serum electrolyte and urinary abnormalities seen in dengue are discussed and Acute Kidney Injury (AKI) due to acute glomerulonephritis, rhabdomyolysis and haemolytic uraemic syndrome following dengue are explored...

BACKGROUND: IgA nephropathy is the most common primary glomerulonephritis worldwide and a significant cause of end-stage renal disease (ESRD). While most cases of IgA nephropathy are considered sporadic, familial cases have been reported. METHODS: We performed a national audit of 1,809 patients attending renal clinics and dialysis units to identify a family history among patients with kidney disease. We reviewed all renal biopsies performed at our institution spanning a 30-year period...

The association between malignant tumors and the occurrence of glomerular disease has been well documented in previous studies. The most common types of malignant tumor include Hodgkin's lymphoma with minimal change glomerular nephritis, solid tumor with membranous nephropathy and renal cell carcinoma with immunoglobulin (Ig)A nephropathy. The present case study describes a case of a 31-year-old Chinese female patient who was hospitalized with chronic glomerulonephritis. The patient self-administered unknown traditional Chinese medicine; however, protein excretion/24-h remained increased compared with normal levels...

Background: C3 glomerulonephritis (C3GN) is caused by alternate complement pathway over-activation. It frequently progresses to end-stage renal disease, recurs in two-thirds of transplants and in half of these cases progresses to allograft loss. There is currently no proven treatment for C3GN. Case Presentation: We describe a family segregating pathogenic alleles of complement factor H and I (CFH and CFI). The only member carrying both mutations developed C3GN. Prolonged delayed graft function after deceased donor transplantation, heavy proteinuria and isolated C3 hypocomplementemia prompted an allograft biopsy confirming diagnosis of recurrent C3GN...

The presence of human immunodeficiency virus (HIV)-related kidney disease is an important cause of mortality and morbidity. HIV infection induces renal injury by direct cytotoxicity or immune complex-mediated glomerulonephritis in patients with genetic susceptibility factors. In the last decades, with the development and diffusion of combination antiretroviral therapy, which has prolonged patient survival, there has been a shift in the spectrum of renal diseases in HIV-infected patients, with the decrease of glomerular diseases and increase in the role of nephrotoxicity and co-morbidities...

Hepatitis C virus (HCV) infection affects many organs in the body, including the liver, kidneys, skin, joints and others. Although the hepatic manifestation of HCV has been widely studied, the extrahepatic manifestaions of HCV have not been fully appreciated. Studies have shown that patients with HCV have a higher risk of chronic kidney disease and end-stage renal disease, as well as poorer outcomes after kidney transplantation. Given these findings, it is important to screen HCV patients for presence of renal impairement in a timely manner...

BACKGROUND: Despite the development of biomarkers and noninvasive imaging tools, biopsy remains the only method for correctly diagnosing patients with unexplained hematuria, proteinuria and renal failure. Renal biopsy has been performed for several decades in Taiwan; however, a national data registry is still lacking until 2013. METHODS: The Renal Biopsy Registry Committee was established within the Taiwan Society of Nephrology in January 2013. A biopsy registry format, including basic demographic data, baseline clinical features, laboratory data, and clinical and pathological diagnosis was developed...
