Korbet SM, et al: In some of these patients, the EM study provides the key information that can not be otherwise obtained. These results show that the EM study is more useful in children with NS in comparison to adults.

As new approaches are developed, morphologic methods, such as the index proposed by Hill et al [9] that focus on reversible pathology and specific pathogenic mechanisms, may be helpful in evaluating therapeutic efficacy. Classification and atlas of glomerular disease. Clinical findings at presentation included renal insufficiency in The two other groups of glomerular diseases for which the EM study was essential were the mesangiocapillary GN MPGN and the hereditary glomperulopathies.

Three patients responded to steroid and cyclophosphamide treatment, although one of them died of acute bacterial bronchopneumonia. No family history was available of renal disease in our case and genetic testing could not be done due to non-availability of this facility.

Genetic and pedigree analysis can resolve the differential in such cases. While glomerular macrophage accumulation correlates with mesangial cell activation alpha-actin expression and collagen deposition, and interstitial macrophage accumulation correlates with interstitial fibroblast activation and collagen deposition, only interstitial macrophages correlate with renal function.


In clasiifcacion, ING is a progressive vasculopathic lesion linked to hypertension and cigarette smoking.

The nodules are Ig deposits and not mesangial matrix. We retrospectively analyzed 90 DPLN patients who were confirmed by kidney biopsy and treated at least for 12 months to compare the effectiveness of treatment modalities and to investigate the prognostic factors of DPLN. TEM or immunohistology are available for the differential diagnosis.

The results demonstrate that the ultrastructural study is both helpful and essential to a correct classification of glomerular diseases underlying NS in children in nearly all cases and whenever feasible this should be used in the pathologic evaluation of renal biopsies. The initial renal insufficiency OR Subscribe to our Newsletter. Magil AB, et al: This clearly shows that the EM study is useful in a vast preponderance of cases of glomerular diseases in childhood NS. Multivariate Cox regression models were used to adjust the risks of graft failure and mortality for group differences in recipient and donor characteristics.

Prodominant tubulointerstitial lupus nefritis. IFM findings were then related to clinical and LM findings and its prognostic value studied by survival analysis.

Diagnostic Pathology

Medium magnification view of glomerular basement membrane GBM showing focal thickening and rarefaction of the lamina densa of the GBM in a case of Alport syndrome. Nodular dense deposit disease DDGN: Their relevance for classification and relationship with clinical and histological findings and outcome.

Positive antinuclear antibody ANA test was found in 8 Am J Med Sci ; glomerulopatias primarias The dysregulated podocyte phenotype: The risk for endstage renal failure in patients with proliferative lupus nephritis PLN depends largely on the severity and reversibility of the inflammatory process as determined by light microscopy LM.

Idiopathic nodular glomerulosclerosis ING is an enigmatic condition that resembles nodular diabetic glomerulosclerosis but occurs in nondiabetic patients. J Pak Med Assoc ; Glomeurlopatias pathological classification of lupus nephritis Ch. Anti-streptolysin O ASO titer was elevated in two cases. Immunohistochemical staining for CD34, a marker of endothelial ee, showed an increased number of vascular channels within ING glomeruli compared with clqsificacion controls.


Diffuse effacement of podocytes. Value of electron microscopy in the diagnosis of childhood nephrotic syndrome. J Am Soc Nephrol 7: Anti-streptolysin O ASO titer was elevated in two cases. J Glomeruoopatias Soc Nephrol Subclinical diabetes mellitus may be detected by other tests: Role of pathology indices in the management of severe lupus glomeruloglomerulonephritis.

Follow-up data were available for 17 patients, 6 of whom reached end-stage renal disease ESRD SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. However, most previous studies examined small numbers of patients and did not adjust for important confounding factors.

We have recently encountered five cases of active diffuse proliferative glomerlonephritis with no subendothelial and few or no mesangial deposits and thrombotic microangiopathy TMA in four patients with SLE and one patient with lupus-like syndrome. In developing the index the authors demonstrated correlations among the morphological features, the component indices, and the clinical parameters that imply that the assignment of the histological elements to the component indices is valid and that the indices reflect the underlying pathogenetic mechanism.

Predictive power of the second renal biopsy in lupus nephritis: Conflicts of interest The authors declare that there is no conflict of interest associated with this manuscript.

However, there is a caveat:
