THE CLINICAL, LABORATORY MANIFESTATIONS AND HISTOPATHOLOGY IN NEPHROTIC PATIENTS WITH LUPUS NEPHRITIS

Abstract

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease involving multiple organ systems. The kidney appears to be the most commonly affected organ, especially nephrotic is a serious kidney injury. The clinical, laboratory manifestations and histopathology are very useful for diagnosis, provide the means of predicting prognosis and guiding therapy in nephrotic patients with lupus nephritis. Methods: Descriptive cross-sectional study of nephrotic patients with lupus treated in the Department of Nephrology Trung Vuong Hospital and Cho Ray Hospital between May/2014 and May/2017. Renal histopathological lesions were classified according to International Society of Nephrology/Renal Pathology Society - ISN/RPS ’s 2003. The clinical, laboratory manifestations and histopathological features were described. Results: Of 32 LN with nephritic range proteinuria cases studied, 93.7% were women. The 3 most common clinical manifestations were edema (93.8%), hypertension (96.8%) and pallor (68.9%), musculoskeletal manifestions (46.9%), malar rash (40.6%). There was significant rise in laboratory and immunological manifestions with hematuria (78.1%), Hb < 12g/dL (93.5%), increased Cholesterol (100%), and Triglycerid (87.5%), Creatinine > 1.4 mg/dL (87.5%), increased BUN 71.9%, ANA (+) 93.8%, Anti Ds DNA(+) 96.9%, low C3: 96.9%, low C4: 84.4%. The most various and severe features were noted in class IV with active tubulointerstitial lesions and high activity index. Conclusion: Lupus nephritis with nephrotic range proteinuria has the more severity of histopathological feature and the more severity of the more systemic organ involvements and laboratory disorders were noted. Key words: Systemic lupus, erythematosus (SLE) lupus nepphritis, clinical
