INTRODUCTION: Little is known about the prevalence of kidney diseases according to renal biopsy in Israel. Since updated literature worldwide emphasizes changing etiologies of chronic kidney disease, it is crucial to research and define the epidemiology and pathology of kidney disease in Israel. Hereby, we introduce an original review of the prevalence of kidney diseases in our study population, which we believe reflects the prevalence of kidney diseases in the population of Israel. AIMS: To investigate the prevalence of kidney diseases diagnosed by renal biopsy, according to age, gender, race and clinical symptoms...

It has been noted that cyclosporine A (CsA) is an effective drug for membranous nephropathy (MN). Diabetes is a common disease that sometimes causes nephrotic syndrome. We report the case of an 89-year-old woman with type 2 diabetes mellitus who exhibited nephrotic syndrome. Examination of a renal biopsy indicated MN and she was prescribed CsA as monotherapy. Her edema subsided and she achieved partial remission. This is the first report of a patient in diabetic condition with MN having achieved partial remission after CsA monotherapy without steroid therapy...

BACKGROUND: Mutations in the AarF domain containing kinase 4 gene (ADCK4), one of the novel genes causing steroid-resistant nephrotic syndrome (SRNS), usually manifest as isolated adolescent-onset focal segmental glomerulosclerosis (FSGS). ADCK4 interacts with components of the coenzyme Q10 (CoQ10) biosynthesis pathway. METHODS: The incidence and phenotypes of patients with ADCK4 mutations were investigated in a cohort of Korean pediatric patients with SRNS. RESULTS: Among the 53 patients enrolled in the study the incidence of ADCK4-associated FSGS was 7...

A 55-year-old man developed rapidly progressive glomerulonephritis and nephrotic syndrome. A kidney biopsy specimen showed diffuse proliferative and crescentic glomerulonephritis with monoclonal IgG1κ, humps, and nephritis-associated plasmin receptor, indicating infection-associated proliferative glomerulonephritis with monoclonal immunoglobulin G deposits (PGNMID). Despite dialysis-dependent renal failure, symptomatic therapy resulted in spontaneous recovery of the renal function, mimicking post-infectious glomerulonephritis (PIGN)...

Renal biopsy is crucial while evaluating for the diagnosis of glomerular, vascular, tubulointerstitial, and genetic diseases. It gives vital information which helps in estimating the disease prognosis, progression, and management. This is the retrospective analysis of all adult patients aged above 18 years, who underwent percutaneous renal biopsy at The Kidney Center Post Graduate Training Institute, Karachi, over a duration of 18 years, i.e., January 1, 1996, to December 2013. Renal graft biopsies and those which were inadequate were excluded from analysis...

BACKGROUND AND OBJECTIVES: A low total nephron number, which is associated with low birth weight (LBW), may indicate increased susceptibility to early-onset renal diseases in children. However, few studies have assessed renal biopsy findings in LBW children. We examined the relationship between LBW and glomerular density (GD) and/or glomerular volume (GV) in renal biopsy samples as a surrogate for total nephron number. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Renal biopsy findings of children of LBW were compared with those of age-matched control subjects of normal birth weight (NBW) who were histopathologically diagnosed with FSGS or minimal change nephrotic syndrome (MCNS) from 1995 to 2011...

Monoclonal gammopathy of renal significance (MGRS) can manifest in many different ways depending on the nature of the immunoglobulin and its physicochemical properties. MGRS can lead to the discovery of a hematological malignancy. We report the case of a 32-year-old female patient who underwent renal biopsy on account of an impure nephrotic syndrome associated with immunoglobulin (Ig)G κ monoclonal gammopathy. Histological analysis revealed membranoproliferative glomerulonephritis with IgG, IgM, κ, λ, and C3 deposits...

This case report discusses the clinical indication for immunosuppressants in patients with idiopathic membranous nephropathy (IMN). Because this disease occasionally shows spontaneous remission, it is necessary to determine the predictive values for a therapeutic effect in order to provide appropriate treatment. Two distinct cases described herein illustrate the different effects of tolvaptan in responders and non-responders, according to the pre-treatment levels of AQP-2 immunostaining in the samples from renal biopsy and urinary levels of AQP-2 and osmolality, suggesting that these values may be useful predictors of response to tolvaptan in patients with nephrotic IMN...

INTRODUCTION: The co-existence of focal segmental glomerulosclerosis (FSGS) and rheumatoid arthritis (RA), presenting either together or in succession, is very rare. A variety of histopathological features in the clinical renal disease may occur in RA. Only 8 studies have previously reported this poorly understood connection. CLINICAL FINDINGS/DIAGNOSES: A case of a 54-year-old male with RA lasting for more than 7 years developed cheirarthritis as the first signs...

Despite being a common procedure, percutaneous renal biopsy (PRB) carries the potential for complications. The British Association of Paediatric Nephrologist (BAPN) has published standards for pediatric PRB. As Indian data are scarce, we conducted a prospective audit of 100 consecutive pediatric renal biopsies (60% males) under real-time ultrasound guidance. Nephrotic syndrome was the most common indication for PRB (68%) with minimal change disease (30%) and focal segmental glomerulosclerosis (25%) being the most common histopathological lesions...

BACKGROUND: Immunoglobulin E (IgE) has traditionally been associated with anaphylaxis and atopic disease. Previous studies reported that serum IgE levels are elevated in nephrotic syndrome and suggested IgE levels as a prognostic indicator in glomerular diseases. The aim of this study was to explore the association between serum IgE levels and renal outcome in patients with immunoglobulin A nephropathy (IgAN). METHODS: We included 117 patients with biopsy-proven IgAN...

BACKGROUND: Idiopathic membranous nephropathy (IMN) is a common cause of nephrotic syndrome (NS) in adults in Western countries. In 2012, the KDIGO (Kidney Disease: Improving Global Outcomes) working group published guidelines for the management of glomerulonephritis, thus providing a template for the treatment of this condition. While being aware of the impact of the clinicians' acumen and that patients may choose a different therapeutic option due to the risks of specific drugs and also of the evolving guidelines, this review details our approach to the management of patients with IMN in a Western center (Toronto)...

BACKGROUND: Membranous nephropathy (MN) is the most common cause of nephrotic syndrome (NS) in adults, accounting for about 20.0% of all NS cases. With an increasing prevalence, especially in the elderly, it has received great attention in Asia. SUMMARY: Recently, the prevalence of idiopathic MN (IMN) has significantly increased among the elderly people in Asia and other places in the world. Although the exact mechanism of IMN remains unveiled, the identification of new antigens such as PLA2R and THSD7A has greatly enhanced our understanding of its pathogenesis...

BACKGROUND: The burden of chronic kidney disease (CKD) in Nigeria is quite alarming. The prevalence of CKD ranges from 11 - 23.5%. Hypertension and chronic glomerulonephritis (CGN) remain the two leading causes of CKD in Nigeria. The etiology of CKD in many of these patients remains unknown, as few biopsies are done. In order to demystify the various glomerular diseases that culminate in CGN, performing a kidney biopsy offers a ray of hope. Few studies on renal biopsies have emanated from Nigeria; this study, however, is unique as the histopathological analysis involves light, immunofluorescence, and electron microscopies...

Renal biopsy was performed for the first time more than one century ago, but its clinical use was routinely introduced in the 1950s. It is still an essential tool for diagnosis and choice of treatment of several primary or secondary kidney diseases. Moreover, it may help to know the expected time of end stage renal disease. The indications are represented by nephritic and/or nephrotic syndrome and rapidly progressive acute renal failure of unknown origin. Nowadays, it is performed mainly by nephrologists and radiologists using a 14-18 gauges needle with automated spring-loaded biopsy device, under real-time ultrasound guidance...

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially fatal condition characterized by skin rash, fever, eosinophilia, and multiorgan involvement. Various drugs may be associated with this syndrome including carbamazepine, allopurinol, and sulfasalazine. Renal involvement in DRESS syndrome most commonly presents as acute kidney injury due to interstitial nephritis. An 11-year-old boy was referred to the Children's Hospital of Pusan National University because of persistent fever, rash, abdominal distension, generalized edema, lymphadenopathy, and eosinophilia...
