The aim of this study was to assess the epidemiology of different patterns of chronic glomerular diseases based on clinical, histopathological and immunofluorescent findings of glomerulonephritis patients hospitalized in the Department of Nephrology, Transplantology and Internal Diseases in Poznan between January 2009 and December 2012. We retrospectively studied 418 patients who had been subjected to renal biopsies. Data on serum creatinine concentration, 24 h proteinuria, arterial hypertension, diabetes mellitus, and histological and immunofluorescent findings were collected. The patients' mean age was 42 ±15. The male sex prevailed (53.1%). Immunoglobulin A nephropathy was the most common finding (18.9%), followed by focal segmental glomerulosclerosis (16.3%), membranous glomerulonephritis (10.1%), lupus nephritis (8.4%), extracapillary glomerulonephritis (3.3%) and membranoproliferative glomerulonephritis (2.6%). In 69 (16.5%) patients the biopsy was non-informative or non-diagnostic. Patients with membranous nephropathy presented the highest frequency of nephrotic syndrome (71.4%), followed by membranoproliferative glomerulonephritis and focal segmental glomerulosclerosis. Combined analysis of the clinical, histopathological and immunofluorescent findings in glomerulonephritis patients based on a single center's data can provide important epidemiological findings.
Role of immunoflourescence in the diagnosis of glomerulonephritis
JPMA. The Journal of the Pakistan Medical Association, 2012
To correlate the findings of immunoflorescence (IF) with morphology in renal biopsies of patients with glomerulonephritis (GN) of both primary and secondary nature. The cross-sectional analytical study was conducted at the Shifa International Hospital's Department of Pathology form March 2007 to August 2008, during which a total of 207 renal biopsies were done. Of them, the study included 92 cases which were diagnosed as primary or secondary glomerulonephritis under light microscope. Those cases were selected in which both light microscopy (LM) and immunoflorescence were done. Of the 92 patients, 79 (85.8%) were adults (> or = 19 years) and 13 (14%) were children (< 19 years). The mean age of adults was 36.44 +/- 11.55 (range 19-69 years) and that of the children was 10.54 +/- 3.85 years (range 4-18 years). immunoflorescence changed the morphologic diagnosis in 20 (21.73%) cases. The pattern of disease was: membranous glomerulonephritis in 24%, focal segmental glomeruloscl...

Introduction: The frequency of primary glomerular diseases is variable from one part of the world to the other. Data published from India has shown wide range of variation in the different regions of the country. Objectives: This study reports the frequency of primary glomerulonephritis (GN) in adults in the Rayalaseema region of south India. Materials and Methods: The study is based on prospective evaluation of renal biopsies done during 2 years 4 months period (May 2010-August 2012). A total of 137 cases of primary GN were studied by light microscopy and immunofluorescence (IF). The patients age range between 15-74 years. Results: Most frequent primary GN was membranous nephropathy (MN) constituting 35.8%, followed by minimal change disease (MCD) at 16.7%. Conclusion: This study demonstrates that MN is the most common primary GN encountered in the adults, the second more frequent is MCD. This result is in contrast to previous reports from India where IgA nephropathy (IgAN) and MCD...
Direct immunofluorescence and immunohistochemistry in diagnostics of glomerulonephritis
Bosnian journal of basic medical sciences / Udruženje basičnih mediciniskih znanosti = Association of Basic Medical Sciences, 2008
The needle biopsies from 60 transplanted and native kidneys have been processed and a prospective analysis of pattern, intensity and distribution of immunoglobulin deposits (IgA, IgG and IgM) and complement components (C3c and C1q) identified in these lesions has been carried out by immunohistochemistry with three step immunoperoxidase, in the period from 2000 to 2004. Those deposits were previously detected and analyzed by immunofluorescence. The samples consisted of 30 renal biopsies, previously diagnosed with glomerulonephritis and positive immunofluorescence and 30 renal biopsies without morphologic changes and deposits on immunofluorescence. 78,7% of the analyzed samples showed the identical results of the deposits of immunoglobulin and components of the complement with both, immunohistochemistry and immunofluorescence method. Sensitivity of the immunohistochemistry method with three step immunoperoxidase for all analyzed immunoglobulin and complement components is high (0,93),...
Morphological Audit of glomerular diseases in a tertiary care Hospital
INTERNATIONAL JOURNAL OF ENDORSING HEALTH SCIENCE RESEARCH (IJEHSR)
Background: Glomerular diseases are a universal health issue, and Pakistan ranks eighth in renal disease, causing 20,000 deaths every year. Renal biopsy is a valuable diagnostic tool and provides prognostic insight and therapeutic plans. The study's objective is to determine the frequency and pattern of various glomerulopathies concerning age and gender. Methodology: A cross-sectional study was performed at the Department of Pathology, Ziauddin Medical University, and Hospital, Karachi, from 19th December 2018 to 15th April 2019. A total of 91 patients were included of either gender with a clinical history of glomerulonephritis. All biopsy samples were analyzed by using light and immunofluorescence microscopy techniques. Patient data were compiled and analyzed through SPSS version 20.0. Results: A total of 91 cases of the renal biopsy were evaluated; 51.6% of these cases were male patients. Forty-nine (53.8%) cases were reported as focal segmental glomerulosclerosis, 35(38.5%) w...

Published studies from different centers in Saudi Arabia have reported contradicting results regarding glomerular lesions. In this retrospective study, we report our experience in King Fahd Hospital of the University at Al-Khobar in the Eastern province, including a description of the morphologic and clinical characteristics of primary and secondary glomerular disease. The study included 233 renal biopsies obtained from patients presenting with glomerular manifestations over a period of 23 years , investigated by light microscopy, immunofluorescence (149 cases) and electron microscopy (34 cases). One hundred and eighty-seven cases (80.3%) were primary glomerulonephritides. Minimal change glomerulopathy was the most common type of primary glomerulonephritis found (29.4% of primary glomerulonephritides), followed by mesangioproliferative glomerulonephritis (19.8%), and focal/segmental glomerulosclerosis (15.5%). Membranoproliferative glomerulonephritis was found in 9.6% of cases, membranous glomerulopathy in 8.6%, IgA nephropathy in 6.4%, end-stage glomerulopathy in 5.9%, crescentic glomerulonephritis in 3.2%, and IgM nephropathy in 1.6%. Of the secondary glomerulonephritides (46 cases constituting 19.7% of the biopsies), lupus nephritis was the most frequently diagnosed disease (71.7% of secondary glomerulonephritides). Diabetic glomerulosclerosis was found in 10.9% of cases, amyloidosis in 6.5%, and Alport syndrome in 4.3%. Wegener's granulomatosis, Henoch-Schönlein purpura nephritis and hypertensive nephrosclerosis each represented 2.2% of cases (one case each). Other than a significantly higher incidence of minimal change glomerulopathy and lupus nephritis (p < 0.001) and a significantly lower prevalence of membranoproliferative glomerulonephritis (p = 0.029), our results are generally comparable to those reported by the Saudi registry for glomerulopathy and in some neighboring countries. Ageand sex-adjusted analyses revealed that minimal change glomerulopathy and lupus nephritis were also the most prevalent primary and secondary glomerulopathies in the pediatric age group (below 15 years) as well as in adults, females and males.

Direct Immunofluorescence of Renal Biopsy: Perspective of an Immunopathologist
Journal of Postgraduate Medicine Education and Research, 2015
Aims: This study was undertaken to analyze the strength of direct immunofluorescence microscopy in the diagnoses of renal diseases vis-à-vis histopathology. An attempt was also made to present advantages and pitfalls of this age old technique. Settings and design: A total of 250 consecutive renal biopsies received over a period of 1 year were analyzed. The histopatholgy and direct immunofluorescence slides were reported by two separate pathologists and later compared to reach a final diagnosis. Results: Two cores examined by histopatholgy and direct immunofluorescence microscopy yielded a final diagnosis in 98% cases. In 2% of renal biopsies (4 biopsies with a 'descriptive' label and 1 case of amyloid like nephropathy), additional diagnostic aids like electron microscopy were required to clinch a conclusive diagnosis. No case of anti-glomerular basement membrane glomerulonephritis or hereditary glomerular disease was observed over 1 year period under review. Conclusion: Direct immunofluorescence helped to detect IgA nephropathy (5% cases), it incresed the sensitivity of detection of focal segmental glomeulosclerosis (23 more cases) and membranous glomerulopathy (2 more cases). It helped in detection as well as grading of glomerulonephritis in lupus nephritis. Crescentic glomerulonephritis could be further categorized into immune complex and pauci-immune subtypes. Immunofluorescent dye thioflavin T proved out to be a very sensitive dye for detection of amyloidosis. Membranoproliferative glomerulonephritis/ diffuse proliferative glomerulonephritis cases were less well discriminated by direct immunofluorescence than histopathology. Two percent of renal biopsies (2 cases of membranoproliferative glomerulonephritis, 1 case of membranous glomerulopathy, 1 case of mesangioproliferative glomerulonephritis) were false negative on direct immunofluorescence implying technical errors. Thus, correct diagnosis of glomerulonephritis requires direct immunofluorescence jpmer original article

Background: Glomerulonephritis (GN) remains the most probable underlying cause of end stage renal disease of uncertain aetiology in many developing countries including Bangladesh. The pattern of glomerular disease varies widely from country to country. In Bangladesh, the incidence and histological pattern of GN is inadequately described. We performed a study, aiming to determine the pattern of GN in a diabetic hospital of our country. Methods: It was a cross-sectional hospital based prospective study conducted at BIRDEM General Hospital starting from July 2013 to December 2014. It included all patients with suspected GN who underwent native kidney biopsy. Results: Total 57 biopsies were performed and four cases other than primary or secondary GN (renal cortical necrosis 1, tubulointertsitial nephritis 2,chronic GN 1) were excluded i.e total number of PGN was 37 and secondary GN was 16. number of patients with were 53. M:F was 1.2:1.Mean age was 42.35±15(14-72) years. Thirty one (58.49%) of the study subjects had diabetes mellitus (DM). Mesangialproliferative GN (15/37,40.5%) and diabetic nephropathy (9/16,56%) were the commonest histopathological pattern found among primary and secondary GN respectively. Membranoproliferative GN (10/37,27%),was the second commonly observed pattern followed by focal segmental proliferative GN (8%), membranous nephropathy (8%), focal segmental glomerulosclerosis (5.4%) in primary GN and lupus nephritis (6/16,38%) and Wegeners granulomatosis (1/16) were other varieties in secondary group. Among 53 cases, 37 had proliferative variety. Nephrotic range proteinuria (41.5%) was the commonest indication of biopsy and 22% had post biopsy bleeding and 3.7% required blood transfusion. Conclusion: In conclusion, mesangial proliferative and membranoproliferative GN are the two common causes of primary GN. Diabetic nephropathy is the commonest cause of secondary GN. Nephrotic range proteinuria was the main indication of biopsy. Post biopsy complication was negligible. Creation of a national renal registry is essential for obtaining more specific epidemiological data.
Spectrum of biopsy-proven glomerular disease in Al Qassim region: A single centre experience
Saudi Journal of Kidney Diseases and Transplantation, 2012
Introduction: Glomerular disease is one of the most common forms of renal disease and can have many different clinical presentations. However there is variation in the prevalence in the type of glomerular disease according to geographical location and race of population. The aim of the study was to find the overall distribution pattern of glomerular disease based on renal biopsies. Material and Methods: The medical records of all children who underwent kidney biopsy (n=29) between January 2012-june 2014 were analyzed. In this retrospective study we review children from Kanti Children's Hospital, Nephrology Department. Demographic data including age, sex and indication of kidney biopsy as well as complication of the procedures were recorded. Result: A total number of thirty one biopsies were done. Two children were excluded from the study due to inadequate tissue and artifacts defects in preservative. The remaining twenty nine biopsies were included in the study and analyzed. Renal disease was found nearly equal in both male and female (51.72% vs. 48.27%).Mean age was 10.95±3.30 years. Maximum number of biopsies (75.86%) was performed between 10-15 years. The most common indication of the kidney biopsy was nephrotic syndrome (steroid resistant nephrotic syndrome and steroid dependent nephrotic syndrome, 31.02% followed by lupus nephritis 27.58%.The most common glomerular disease were focal segmental glomerulosclerosis and lupus nephritis both contribute 27.58%. Among lupus nephritis class III was found more common (44.44%) in children. IgA nephropathy was also contribute (17.24%) in all glomerular disease. Regarding the kidney biopsy complication gross hematuria was observed in 6.89% of children which was self-limited. Conclusion: FSGS and lupus nephritis is becoming the most common glomerular disease in children attending the Kanti Children Hospital.IgA nephropathy was also contribute the glomerular disease in the children.
Kidney biopsy in glomerular disease: a hospital based study
Journal of Patan Academy of Health Sciences, 2017
Introductions: Kidney biopsy is the standard tool to diagnose glomerular disease (GD). There is lack of national registry of kidney biopsy for the type, incidence and prevalence of GD. We aim to review kidney biopsy at Patan Hospital for profile of GD in local scenario. Methods: This was a chart review of patients who underwent kidney biopsy at Patan Hospital, Nepal, from October 2013 to September 2015. We analyzed the data for indication of kidney biopsy, types of GD and complication of biopsy. Results: There were 117 patients who had kidney biopsies. Immunoglobulin A Nephropathy was seen in 42 (35.8%) and Lupus Nephritis in 38 (32.5%). Sub nephrotic range proteinuria with or without active urinary sediments was found in 75 (64%). Blood transfusion was required in 3 (2.5%) patients after biopsy. There was no surgical intervention or mortality related to biopsy. Conclusions: IgA Nephropathy was the commonest glomerular disease. Kidney biopsy was a safe and effective procedure.
