Abstract INTRODUCTION: Lupus nephritis (LN) is a major complication of systemic lupus erythematosus (SLE). Renal involvement is a major determinant of the prognosis of SLE. The histological classification of LN is a key factor in determining the renal survival of patients with LN. Prompt recognition and treatment of renal disease are important, as early response to therapy is correlated with better outcome and renal biopsy plays an important role in achieving this. OBJECTIVES: The objective of this study was to correlate the clinical and laboratory findings with histopathological classes of LN as per the 2003 International Society of Nephrology-Renal Pathology Society (ISN/RPS) classification system. PATIENTS AND METHODS: Fifty-six patients with SLE, undergoing a renal biopsy for renal dysfunction were studied. The comparison of data from multiple groups was made by Pearson’s Chi-square test and between two groups by independent samples t-test. The values of P < 0.05 were considered statistically significant. RESULTS: Of the 56 cases studied, 51 (91.1%) were females. The most common presenting symptoms were edema, arthralgia, and hypertension. Class IV (55.4%) was the most common class. Thirty-nine (69.6%) cases showed full house immunostaining. Hypertension, hematuria, proteinuria, and tu bulo-interstitial disease showed a significant correlation (P < 0.05) with ISN/RPS classification, 2003. CONCLUSION: Assessment and management of patients with suspected LN are greatly facilitated through information obtained by renal biopsy. Since renal morphology may predict long-term prognosis, and no clinical or laboratory feature uniformly predicts prognosis, it is important to study the constellation of features in LN for better patient management.

Background: A revision of the International Society of Nephrology/Renal Pathology Society (ISN/RPS) classification for lupus nephritis has been published in 2018. The current study aimed to verify the utility of this system. Materials and Methods: A total of 101 lupus nephritis patients from a large Chinese cohort who underwent renal biopsy in Peking University First Hospital were reevaluated by 2 renal pathologists, who had no knowledge of the clinical findings. The association between clinical data at the time of initial renal biopsy and follow-up and pathological features were further analyzed on all patients selected. Results: The mean age of the cohort was 33 years with a male/female ratio of 1:9, and a median follow-up period of 128 months. The presence and extent of mesangial hypercellularity, endocapillary hypercellularity, global and segmental glomerulosclerosis, neutrophil exudation/karyorrhexis, glomerular hyaline deposits, extracapillary proliferation (crescents), tubular atrophy/interstitial fibrosis, and interstitial inflammation were significantly correlated with several clinical renal injury indices (systemic lupus erythematosus disease activity index, serum creatinine value, proteinuria, and C3 level) at the time of biopsy. By multivariable Cox hazard analysis, fibrous crescents, tubular atrophy/interstitial fibrosis, and the modified National Institutes of Health chronicity index were independent risk factors for patients’ composite renal outcomes (hazard ratio [HR] 4.100 [95% CI 1.544–10.890], p = 0.005; HR 8.584 [95% CI 2.509–29.367], p = 0.001; and HR 3.218 [95% CI 1.138–9.099], p = 0.028; respectively). Conclusions: The 2018 revision of the ISN/RPS classification for lupus nephritis has utility for prediction of clinical renal outcomes.

Lupus Glomerulonephritis

Abstract Context.—Systemic lupus erythematosus is an autoimmune disease with protean clinical and pathologic manifestations involving almost all organs in the body. There is a high incidence of renal involvement during the course of the disease, with varied renal pathologic lesions and diverse clinical features. A renal biopsy examined by routine light microscopy, immunofluorescence, and electron microscopy contributes toward diagnosis, prognostic information, and appropriate management. Objectives.—(1) To review the clinical and various pathologic features of renal lesions in systemic lupus erythematosus patients. (2) To introduce the International Society of Nephrology and Renal Pathology Society Classification of Lupus Glomerulonephritis. Data Sources.—A literature review, illustrations with original artwork, and tabulation of clinical and pathologic data of cases obtained from the authors' renal biopsy files examined during the last 8 years were used. Conclusions.—The International Society of Nephrology/ Renal Pathology Society–sponsored Classification of Lupus Glomerulonephritis proposes standardized definitions of the various pathologic findings, describes clinically relevant lesions, incorporates prognostic parameters, and recommends a uniform way of reporting the renal biopsy findings. Lupus glomerulonephritis is divided into 6 classes primarily based on the morphologic lesions, extent and severity of the involvement, immune complex deposition, and activity and chronicity. Special emphasis is laid on describing qualitative as well as quantitative morphologic data and to include the accompanying tubulointerstitial disease and different vascular lesions, which have prognostic and therapeutic significance. This classification is intended to facilitate a higher degree of reproducibility, resulting in better patient care and more effective future clinical and translational research. Renal biopsy findings in systemic lupus erythematosus add new and independent parameters of prognostic significance to established clinical and genetic factors.

Introduction: Lupus nephritis is a serious complication of systemic lupus erythematosus. Currently, therapy is guided by findings in the renal biopsy, following the International Society of Nephrology / Renal Pathology Society classification. Austin and Hill’s histomorphological indexes are not routinely obtained. In this retrospective single-centre study, we aimed to analyze the importance and applicability of the different morphological indexes in predicting response to treatment and prognosis.Material and Methods: Patients with kidney biopsy demonstrating lupus nephritis from the 2010 – 2016 period were included. We analyzed their demographic data, comorbidities, clinical presentation and laboratorial evaluation at the time of renal biopsy. We evaluated the following outcomes: clinical remission, renal function and proteinuria at end of follow-up. Histologic analysis was performed using the International Society of Nephrology / Renal Pathology Society classification and the morphological indexes described by Austin (Activity and Chronicity) and Hill. Univariate and multivariate statistical analysis was performed using STATA software.Results: We analyzed 46 biopsy-proven lupus nephritis cases, with a median follow-up of 31.9 (13.2 – 45.6) months. Based on biopsy findings, 35 patients were started on immunosuppressive therapy. We observed that Class IV patients had, at presentation, lower estimated glomerular filtration rate (67.3 vs 94.6 mL/min; p = 0.02), higher proteinuria (4.26 vs 2.37 g/24 hours; p = 0.02) and a non-significantly higher C3 consumption (58.9 vs 77.4 mg/dL; p = 0.06). We did not observe correlations between International Society of Nephrology / Renal Pathology Society classification and the outcomes at the end of follow-up. In contrast, both the Hill biopsy index and Austin’s Chronicity index were correlated with renal function and proteinuria at the end of follow-up. Austin’s Activity index correlated with the immunological findings (C3, C4 and anti-dsDNA) at presentation.Discussion: Because clinical activity poorly correlates with histologic activity, histological findings are fundamental when assessing patients with suspected lupus nephritis. The most recent International Society of Nephrology / Renal Pathology Society report supports the European League Against Rheumatism guidelines, encouraging the adoption of histomorphological indexes when evaluating lupus nephritis. Our data, showing a correlation between the renal outcomes and the indexes described by Austin and Hill, supports this view.Conclusion: The histomorphological indexes in lupus nephritis are easily obtainable, can predict renal outcomes and may help in the management of such patients.
