Chronic kidney disease and acute kidney injury are being increasingly recognized in very elderly patients, aged 80 or more. In cases of suspected glomerulonephritis with or without nephrotic syndrome, the clinical decision-making of whether to obtain a renal biopsy and treat with immunosuppressive therapy should not be based on advanced age alone but take into consideration the patient's functional status and overall prognosis. Herein, we report a case of an elderly patient with minimal change disease who benefitted from a timely renal biopsy and aggressive immunosuppressive therapy...

We report here a case that highlights tuberculosis (TB) as a possible cause for pauci-immune crescentic glomerulonephritis (c-GN), an important and often treatable cause of kidney injury. A 47-year-old HIV-negative man of mixed ethnicity presented with a 2-week history of cough, haemoptysis and unintentional weight loss. Chest examination revealed crepitations over the right upper zone and urinalysis demonstrated an active urinary sediment with red cell casts. Chest radiograph confirmed right upper lobe cavitation...

Tumor necrosis factor (TNF)-α has been reported to be important in glomerulonephritis, which is closely associated with podocyte dysfunction and apoptosis. However, the precise mechanisms by which TNF-α expression are regulated remain unclear. The purpose of the present study was to investigate the role of microRNA (miR)-130a-3p/301a-3p in the post-transcriptional control of TNF-α expression and high glucose (HG)-induced podocyte dysfunction. Mice MPC5 podocytes were incubated with HG and transfected with miR-130a-3p/301a-3p mimics or inhibitors, reactive oxygen species (ROS) levels were measured by flow cytometry assay, and the mRNA and protein levels were assayed by using reverse transcription-quantitative polymerase chain reaction and western blotting, respectively...

Persistent infection with hepatitis B virus (HBV) may lead to HBV-associated glomerulonephritis (HBV-GN). Presence of HBV-DNA and -RNA in renal tubular epithelial cells (RTECs) suggests direct virus-induced injury. Increase in proinflammatory cytokines is also observed under these conditions. Apoptosis by tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) plays a significant role in the pathogenesis of HBV-infections. However, the effects of HBV X protein (HBx) on TRAIL-induced apoptosis of RTECs especially under certain inflammatory conditions remain obscure...

Neuronal intranuclear inclusion disease (NIID) is a relatively new entity identified as a progressive neurodegenerative disease characterised by eosinophilic hyaline intranuclear inclusions widely observed in neuronal and somatic cells. Renal biopsy from one of our patients with NIID showed lupus nephritis-like pathology. He was treated with steroids and angiotensin-converting enzyme inhibitors and his proteinuria improved. The present case highlights that immune-mediated glomerulonephritis can be a presenting feature of NIID, which can be controlled with proper treatment...

We report a case of glomerular basement membrane crescentic glomerulonephritis and multicentric Castleman disease-associated interstitial nephritis in a patient with human immunodeficiency virus (HIV) infection. The patient received corticosteroids, cyclophosphamide, and plasmapheresis, and within 3 weeks, there was worsening thrombocytopenia, anemia, and renal function requiring initiation of hemodialysis. He then received 8 weekly doses of rituximab, and there was steady improvement in renal function, such that he stopped dialysis within 6 weeks and has remained in disease remission at 1-year follow-up...

Neuropsychiatric systemic lupus erythematosus (NPSLE) has a wide variety of neurologic and psychiatric features. NPSLE symptoms and the psychotic features of primary psychiatric disorders often overlap with each other. These psychotic features often mask and delay the diagnosis of NPSLE. We present the case of a 59-year-old female previously diagnosed with bipolar disorder and generalized anxiety disorder presenting with altered mental status (AMS), subsequently diagnosed with neuropsychiatric lupus. Initially, medication overdose was suspected as an empty bottle of trazodone was found beside her...

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...

INTRODUCTION: Burkitt's lymphoma (BL) is an exceptional cause of acute renal failure (ARF). The origin of the tumor clone may be lymphoid follicles secondary to renal Epstein-Barr virus (EBV) infection. With the presentation of this clinical case, the pathogenesis, diagnostic criteria and evolution of this extremely rare affection will be discussed. OBSERVATION: A 4-year-old patient with a recent history of acute osteomyelitis of the right thigh presented an ARF without indications of post-infectious glomerulonephritis...

Senescent cells have deleterious effects on the tissue microenvironment through proinflammatory senescence-associated secretory phenotypes; meanwhile, the onset of glomerulonephritis is predominant in younger adults. To clarify the influence of aging on the onset and development of glomerulonephritis, we used a murine model of antibody-mediated nephritis. Sheep nephrotoxic serum was administered in C57BL/6J mice at 12 weeks (adult) or 18 months old (aged) after pre-immunization with sheep IgG. Depositions of sheep IgG and autologous mouse IgG along the glomerular basement membrane and the serum titer of anti-sheep IgG-specific mouse IgG were similar between adult and aged mice...

BACKGROUND: The balance of several cytokines likely influences the resolution of glomerulonephritis. Monocyte chemoattractant protein-1(MCP-1) is a chemokine that promotes renal inflammation whereas epidermal growth factor (EGF) stimulates protective responses. Previously, high urine MCP-1(MCP-1) and low urine EGF (EGF) levels were found to be associated with tubulointerstitial fibrosis, but there is limited information on the value of these mediators as predictors of therapeutic responses or long term outcome in primary glomerulonephritis...

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...

Immunoglobulin A nephropathy (IgAN) is the most commonly occurring glomerulonephritis. Recurrence of disease in the transplanted kidney can significantly reduce allograft survival rates. Currently, there is no definitive management plan for IgAN recurrence in a transplant that reduces the rate of decline of allograft function and prolongs time to dialysis or re-transplantation. Herein we present a 48-year-old man who had received a renal transplantation in 2006 following his diagnosis of IgAN. In 2015, the patient was noted to have an elevated blood pressure and proteinuria (urinary protein:creatinine ratio [uPCR] 170 mg/mmol)...
