Although the role of extracellular matrices in the development of glomerulosclerosis has been discussed widely, the cellular origin of type VI collagen in diabetic nephropathy (DN) has remained relatively unexplored. This study reports the distribution and cellular origin of type VI collagen in DN. Type VI collagen‐specific oligonucleotide probes and monoclonal antibody were used to assess the relative expression of mRNA for \alpha1 (VI) chain and its translated protein in paraffin‐embedded renal biopsy sections of DN. By immunohistochemistry, compared to the control, increased deposition of type VI collagen was noted in the diffuse and nodular lesions of diabetic glomeruli. For cellular localization of type VI collagen mRNA, paraffin‐embedded renal sections of the control and DN were hybridizedin situwith digoxigenin (Dig)‐labeled antisense oligo‐DNA probe complementary to a part of \alpha1 (VI) mRNA. In comparison to the control kidney sections, increased numbers of intraglomerular cells (both mesangial and epithelial cells) were positive forα1 (VI) mRNA in renal biopsy sections of DN. From the results, we conclude that overexpression of type VI collagen by intraglomerular cells with its increased deposition might significantly contribute to the glomerulosclerosis found in DN.

Immunoglobulin A nephropathy (IgAN) is the commonest pattern of glomerulonephritis identified in areas of the world where renal biopsy is widely practised. It is defined pathologically by IgA deposition in the glomerular mesangium accompanied by a mesangial proliferative glomerulonephritis which may vary greatly in severity. Aetiology is uncertain, but abnormalities of IgA1 hinge-region ...

Interleukin-4 (IL-4) has been recently implicated in the pathogenesis of glomerulonephritis. However, the expression of IL-4 and IL-4 receptor (IL-4R) in human kidney has not been fully determined. Nonradioactive in situ hybridization was used to examine the expression of IL-4 mRNA and IL-4R mRNA in tissues from normal kidneys and specimens from a variety of human kidney diseases. In normal glomeruli, a few mesangial cells and cells of the Bowman's capsule weakly expressed IL-4 and IL-4R mRNA, whereas in diseased glomeruli both mRNA types were strongly expressed in resident glomerular cells, including mesangial cells, glomerular epithelial cells, and cells of the Bowman's capsule. The relationship between the expression of these mRNA and the degree of glomerular injury was different in different types of glomerulonephritis. In IgA nephropathy and non-IgA mesangial proliferative glomerulonephritis, IL-4 expression correlated positively with the degree of mesangial hypercellularity and extracellular matrix expansion. However, IL-4R expression was relatively constant. In contrast, the expression of IL-4 and IL-4R mRNA correlated negatively with the degree of glomerular injury in lupus nephritis. Coexpression and discordant expression of these mRNA forms were observed in individual cells. In tubulointerstitium with severe lesions, IL-4 mRNA and IL-4R mRNA were observed in atrophic tubules and some of the infiltrating cells and fibroblasts. The interstitial expression of these mRNA forms was similar in IgA nephropathy, non-IGA mesangial proliferative glomerulonephritis, and lupus nephritis and correlated positively with the degree of tubulo-interstitial changes. These results suggest that an autocrine and/or paracrine pathway of IL-4 is present in human diseased kidneys and that IL-4 may be involved in tissue injury in glomerulonephritis.

Nephritic Syndrome

Background : Nephrotic syndrome (NS) is one of the most common renal diseases in children. The cause of idiopathic nephrotic syndrome is still unknown. Once the prevalence of minimal change nephritic syndrome occupied the three forth portion of the total renal pathology and most of them were steroid sensitive. But list of steroid insensitive nephritic syndrome become more longer today. Therefore renal biopsy is essential for histopathological diagnosis which guides the most accurate way for the treatment of such diseases.Objective : The objective of this study was to find out the pattern of renal histopathology of selected cases of Idiopathic nephritic syndrome.Materials and Method : This prospective study was conducted from January 2004 to December 2015 among children who were suffering from nephrotic syndrome admitted in Paediatric nephrology department, National Institute of Kidney Diseases and Urology(NIKDU), Dhaka. Renal biopsy were done who fulfil the inclusion criteria. Obtaining ultrasound-guided percutaneous renal biopsy specimens by means of an automated biopsy gun, were evaluated histopathologically under light and direct immunoflurescent(DIF) microscopy by an experienced histopathologist.Results : Total admitted childhood nephrotic syndrome during this period was 1512 and renal biopsy was done in 354 patient. Among the 354 children, histopathological findings were mesangial proliferative glomerulonephritis [MesPGN]was 92(25.98%),minimal change disease[MCD]was79 (22.32%), IgM nephropathy[IgMN]was69(19.49%), focal segmental glomerulosclerosis[FSGS] was 37(10.45%), membranoproliferative glomerulonephritis [MPGN] was 37(10.45%), IgA nephropathy [IgAN] was 20(5.65%),membranous nephropathy[MN] was 08(2.27%) and others were 12(3.39%).Conclusion : In this study we found that theselected patient for renal biopsy in the last 12 years showed that minimal change disease had been decreasing but the other histological types are increasing gradually such as mesangial proliferative glomerulonephritis, FSGS and IgM nephropathy.Northern International Medical College Journal Vol.8(1) July 2016: 165-169

Twenty one cases of hepatoesplenic schistosomiasis patients without clinical and laboratory evidence of renal disease, were studied by surgical biopsies using light microscopy and immunofluorescence. The cases were classified histologically as: normal pattern (6 cases); minimal changes (6 cases); and mesangial proliferative glomerulonephritis (9 cases). By the immunofluorescence microscopy using anti IgM, IgG, IgA and C3, the predominant finding in all biopsies, except the normal cases, was granular deposits of IgM in the mesangium along with C3. On the other hand, IgG was present in all cases including normal biopsies along the capillary walls. However IgG was also present in the mesangium only in cases with glomerular lesions. This finding may well be similar to that recently described as IgM mesangial nephropathy. According to our cases a mesangial proliferative glomerulonephritis, characterized by segmental cell proliferation and deposition of IgM in the mesangium, is probably the entity found in the early stages of mansonic schistosomiasis.

Introduction: Kidney Biopsy is an important diagnostic tool in Nephrology. It is useful in Nephrology in terms of diagnosis, prognosis and management. There is little information on renal biopsy data from central Nepal. We describe our center`s experience in kidney biopsy in term of histological patterns, complications and outcomes.Methods: We prospectively analyzed the biopsies data of patients over a period of one and half year. All kinds of kidney disease patients were included for kidney biopsy, irrespective of their clinical syndromes and underlying diagnosis.Results: A total of 75 biopsies were analyzed. Majority of them were females; 56% (n=42). Most of the biopsies; 84% (n=63) were from younger subjects ≤ 45 years and majority of them fell in the age group 11-20 years. Most common clinical renal syndrome to undergo biopsy was Sub Nephrotic range Proteinuria in 53.3% (n=40). Among comorbid conditions, 53.3% (n=40) had Hypertension. The most common histological pattern seen was Mesangial proliferative Glomerulonephritis (MesPGN) seen in 24% (n=18). Among complications associated with the procedure, macroscopic hematuria was seen in 6.7% (n=5) cases and clinically significant perinephric hematoma causing pain was seen in 5.3% (n=4). There was no mortality associated with biopsy procedure.Conclusions: Sub Nephrotic range Proteinuria was the commonest clinical renal Syndrome observed. In terms of renal histology, Mesangial Proliferative Glomerulonephritis (MesPGN) was the commonest histological pattern observed. Kidney biopsy is a safe procedure without any significant adverse events.Keywords: Kidney biopsy, sub nephrotic range proteinuria, mesangial proliferative glomerulonephritis
