As the life expectancy is increasing, there is a rise in elderly population and consequent increase in the patients with renal disease. There is an inconsistency between clinical and histopathological diagnosis in elderly, and so renal biopsy is important in these patients to decide appropriate clinical management and prognosis. This study outlines the importance of renal biopsy in elderly and describes the clinical and pathologic spectrum of renal diseases in patient ≥60 years. All patients (age ≥60 years) undergoing renal biopsies from January 2011 to December 2014 were included in this retrospective study...

In tumor nephrectomy specimens, the evaluation of the normal renal parenchyma is often overlooked. A patient with both end-stage renal diseases (ESRDs) with a renal cell carcinoma is more likely to die of the ESRD rather than cancer. At the time of nephrectomy, a pathologist has a large amount of tissue available to him to comment upon the presence of disease in the nonneoplastic kidney. Hence, this study was undertaken with the idea of characterizing disease in the nonneoplastic kidney at the time of tumor nephrectomy...

PURPOSE OF REVIEW: Immunoglobulin A (IgA) nephropathy (IgAN) is a heterogeneous disease, and predicting individual patient risk of renal progression is challenging. Recent studies provide new evidence regarding the use of clinical, histologic, and biomarker predictors of renal outcome in IgAN. RECENT FINDINGS: A meta-analysis of clinical trials demonstrated that early change in proteinuria is a valid surrogate outcome measure for longer term decline in renal function, which supports the use of proteinuria to dynamically re-evaluate patient prognosis over time...

The renal prognosis and treatment of primary IgA nephropathy (IgAN) patients with segmental glomerular necrosis (SGN) remain controversial. Patients with primary IgAN confirmed by renal biopsy were enrolled. Patients with SGN on renal biopsy were selected as the necrosis group, and a propensity score matching method was used to match a control group according to age, gender, weight, height and follow-up time. A total of 825 IgAN patients were enrolled in the present study. Seventy-three (8.8%) patients with SGN were selected as the necrosis group, and 292 patients without SGN were matched as the control group...

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)...

Anticoagulant-related nephropathy (ARN) was initially described in patients on warfarin (as warfarin-related nephropathy) and recently in those using dabigatran. Herein, we report clinical history and kidney biopsy findings in a patient on apixaban (Eliquis). Initiation of treatment with apixaban resulted in aggravation of preexisting mild acute kidney injury (AKI). A few days after apixaban therapy, the patient became oligoanuric, and kidney biopsy showed severe acute tubular necrosis with numerous occlusive red blood cell casts...

BACKGROUND: To clarify the long-term efficacy of multiple-drugs combination therapy (PWDM) and tonsillectomy pulse therapy (TPT) for pediatric IgA nephropathy (IgAN), we retrospectively evaluated the clinical and laboratory findings as well as the prognosis for IgAN patients treated with each treatment at long-term follow-up. METHODS: We collected data on 61 children who had been diagnosed with severe IgAN. The children were retrospectively divided into two groups...

BACKGROUND: The widely used International Study of Kidney Disease in Children (ISKDC) classification for Henoch-Schönlein purpura nephritis (HSPN) does not completely correlate with the clinical presentation and long-term prognosis of this disease. Primary IgA nephropathy (IgAN) and HSPN share common features; thus, the Oxford classification of IgAN might be useful in predicting the long-term outcomes of HSPN. However, its value has not been confirmed in children with HSPN. METHODS: We selected children with HSPN diagnosed between 2003 and 2015, and reclassified their renal biopsies according to the Oxford classification scoring system...

BACKGROUND: We evaluated whether the serum IgA/C3 ratio and glomerular C3 staining predict prognosis in IgA nephropathy. METHODS: We collected data for 44 IgA nephropathy children treated with multi-drug combination therapy. The children were retrospectively divided into four groups based on the serum IgA/C3 ratio and glomerular C3 staining. Group A consisted of 9 children with a higher than median IgA/C3 ratio and glomerular C3 staining ≧2.0, Group B consisted of 7 children with a higher than median IgA/C3 ratio and glomerular C3 staining <2...

IgA nephropathy, the most prevalent form of primary glomerular disease, usually portends a favourable outcome. Antineutrophil cytoplasmic autoantibodies (ANCAs) have been reported in association with IgA nephropathy in a small subset of patients, mostly presenting with rapidly progressive glomerulonephritis and necrotising crescentic lesions. Herein, we describe a case of IgA nephropathy, positive serum cytoplasmic and perinuclear ANCAs with anti-myeloperoxidase antibody, and preserved renal function without any histological evidence of necrotising or crescentic glomerulonephritis...

INTRODUCTION: The possible confounding influence of investigator-related preferences, available histological techniques, and healthcare systems on the frequencies and incidences of primary and secondary nephropathies was evaluated in this long-term observation. MATERIALS AND METHODS: The observation time from 1983 to 2010 was divided in regard to the political regimes: a) prior to and after German reunification: German Democratic Republic (GDR, period 1 from 1983 to 1990)/Federal Republic of Germany (FRG, period 2 from 1990 to 2010); and the two heads of the division of nephrology, b) conductor 1 (1983 - 2006) and conductor 2 (2006 - 2010)...

BACKGROUND: Information on long-term renal outcome of pediatric glomerulonephritis associated with crescent formation is limited. A single center retrospective study was conducted to assess long-term renal survival and to determine whether the 2010 classification for antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis can predict renal outcome in pediatric glomerulonephritis associated with crescent formation. METHODS: Biopsy and clinical data of children, aged ≤ 18 years with ≥ 10 glomeruli and ≥ 10% crescentic glomeruli during January 1998 to December 2015, were reviewed...

A 54-year-old woman presented with atypical chest pain, fever and malaise. She was immunosuppressed with three agents following a living-donor kidney transplant 1 year previously. Her native kidney failure was secondary to biopsy-demonstrated crescentic IgA nephropathy, with systemic involvement. A CT pulmonary angiogram revealed an inflammatory cuff of soft tissue around the descending thoracic aorta suggesting aortitis. Inflammatory markers were elevated. Given her immunosuppression, the patient was screened extensively for infective causes and was empirically commenced on intravenous meropenem...

We present the case of a 75-year-old Hispanic woman with known stage 3 chronic kidney disease, long-standing hypertension and type 2 diabetes mellitus who presented with right-sided abdominal pain and acute kidney injury, nephrotic range proteinuria with positive antimyeloperoxidase antibody. A renal biopsy revealed IgA nephropathy with superimposed pauci-immune antineutrophilic cytoplasmic antibody (ANCA)-associated crescentic glomerulonephritis. The patient was treated with pulse intravenous methylprednisolone, cyclophosphamide and plasmapheresis...

Background: It has been suggested that the prognosis of immunoglobulin (IgA) nephropathy (IgAN) is adversely affected if there is codeposition of IgG in the glomeruli or if immune deposits are present in the glomerular capillary walls. We sought to understand how these variables affect clinical outcome. Methods: A total of 80 IgAN biopsies were retrospectively divided into groups: (i) IgA without IgG deposition versus IgA + IgG and (ii) immune deposits restricted to the mesangium versus mesangium and peripheral capillary walls (PCWs)...

Kidney diseases affect many hospitalized patients and contribute to morbidity and mortality. Therefore, kidney disease should be prevalent, but the frequency and spectrum of medical renal pathology in autopsy specimens has not been well documented. We sought to determine the spectrum of medical renal pathology in adult autopsy specimens and the frequency of overlooked diagnoses. We reviewed the hematoxylin- and eosin-stained kidney sections from 140 adult autopsies performed at a large teaching hospital over a 2-year period...

Strongyloid hyperinfection is seen in immunocompromised individuals with underlying lung disease. The use of immunosuppressive drugs is an important risk factor. We report a case of IgA nephropathy with crescent, started on glucocorticoid and mycophenolate mofetil. He presented with bilateral lung opacities with breathlessness. As the breathlessness was not improving, despite adequate ultrafiltration, bronchoscopy was done. Bronchoalveolar lavage fluid examination showed the presence of strongyloid larvae, which was later demonstrated in stool also...

REVIEW
John Feehally
The role of immunosuppression in IgAN remains controversial despite a growing evidence base of randomized controlled trials (RCTs). In IgAN with nephrotic syndrome the role for corticosteroids is limited to cases with minimal change on light microscopy. In crescentic IgAN, the use of immunosuppression is supported only by anecdotal data, and outcome may be poor especially when glomerular filtration rate is impaired severely at presentation or there are pathologic features of chronic injury. In slowly progressive IgAN, prediction of outcome now is based both on clinical and pathologic features...
