Diagnostic Pathology

Prognostic factors in diffuse proliferative lupus nephritis. Copyright Copyright S. MCD was the second most frequent lesion underlying NS in children in this study.

Clinicopathologic correlations in lupus nephritis in Lima, Peru. Bacterial infection-related glomerulonephritis in adults. These results show that the EM study is more useful in children with NS in comparison to adults. The demographic characteristics of 74 children showed the mean age of Minimal change disease in systemic lupus erythematosus.

Dee recent reviews of completely worked-up renal biopsies in patients with nephrotic syndrome NSwe have found that the pattern of glomerular diseases, in both the children and the adults, is more akin to that reported recently in developed parts of the world, rather than the glomerulopwtias pattern reported in earlier studies from Pakistan. This is concordant with several recent studies from around the world, which show that the incidence of this lesion is on the rise in children with NS 9.

Kaplan-Meier survival curves were plotted and the results were compared using log rank test. A clinical and pathologic study based on renal biopsies. Identification of the predictors of outcome would help to improve the management.

Transmission electron microscopy, uranyl acetate and lead citrate, x 8, From the lesions discribed in diabetic nephropathy, the more especific is probably nodular glomerulosclerosis K-W lesion. 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.

The renal biopsies were processed for LM examination according to established protocols, df described in detail in our earlier study. We acknowledge the fact the potential role of EM in establishing a diagnosis of MCD in a pediatric population is not without controversy, especially, in the perspective of developing countries.

IFM findings were recorded in terms of the localization glomerular, tubular or vascular and intensity of fluorescence score from zero to three. The final diagnoses arrived at by combining the LM, IF and EM studies with the clinical and the serological clasifivacion, are shown in Table 2.

Similar comparisons were performed between se with ESRD caused by lupus nephritis and 10, adults with ESRD caused by other causes after first living-related renal transplantation. Contributions to the development of SLE in humans include multiple genetic factors such as intrinsic immunological abnormalities, MHC genes, sex hormones, and environmental factors such as infectious agents, among others, with a complex network involved in its regulation.

The two other groups of glomerular diseases for which the EM study was essential were the mesangiocapillary GN MPGN and the hereditary glomperulopathies. Role of pathology indices in the management of severe lupus glomeruloglomerulonephritis.

In any case, the limitation in caring clasififacion patients with lupus nephritis is not only identification of those with the worse prognosis.

However, histological indices have been criticized because the AI does not predict outcome, and study of the CI yields mixed results, with some investigators finding them prognostically useful while others find that they do not predict outcomes [reviewed in 8]. A new morphologic index for the evaluation of renal biopsies in lupus nephritis.

IgMN has also emerged as an important cause of idiopathic NS in children in our part of the world. Identification of specific pathologic features affecting renal outcome. The same as above the nodules are protein and stain dark blue. Positive antinuclear antibody ANA test was found in 8 APGN humps superimposed on diabetic glomerulosclerosis. In our previous analysis of percutaneous native renal biopsies over 14 year period, this lesion closely followed MCD in children as a cause of idiopathic NS INS.

Aunque se puede dar en cualquier paciente, se da con mayor glomerulopatias primarias en la glomerulopatias primarias negra con un ratio Br Med J ; 2 Transplantation ; 9: Contributions of clinical and histologic data. Dische FE, Parsons V.



It is apparent from these tables that the morphological patterns of glomerular injury as seen glonerulopatias LM are not synonymous with the final diagnoses, the later can only be reached by a correlative approach combining information from LM, IF and EM study with the clinical, laboratory and serological data. The study was approved by the ethical review committee of SIUT.

Other morphological appearances were rare. Clinicopathologic characteristics and steroid response of IgM nephropathy in children presenting with idiopathic nephrotic syndrome. Diffuse proliferative lupus nephritis: Clinical outcome of three discrete histologic patterns of injury in severe lupus glomerulonephritis.

Glycosilated hemoglobin, tolerance tests. These were examined statistically to choose the combinations of variables with the highest overall correlations with clinical and outcome parameters. Couser WG, et al: The presence of glomerular macrophages correlated with both glomerular alpha-actin expression and type IV collagen deposition, but did not correlate with renal function or proteinuria.

To evaluate the contribution of electron microscopy EM to the accurate diagnosis of glomerulopathies in childhood nephrotic syndrome NS in a developing country. Subscribe to our Newsletter. Proc Roy Soc Med ; As is evident, the focal and segmental sclerosing lesion was the most common morphological pattern, followed by minor changes and mesangial proliferative pattern. Idiopathic nodular glomerulosclerosis ING is an enigmatic condition that resembles nodular diabetic glomerulosclerosis but occurs in nondiabetic patients.

Check list and assessment of activity and chronicity: Pakistan too, being a developing country, lacks widespread availability of EM facilities. Irreproducibility of the activity and chronicity indices limits their utility in the management of lupus glomerulonephritis.

We have earlier reported on the role of IF and EM in the evaluation of renal biopsies in NS in a study that included both the children and the adults.
