BackgroundClinical distinction between patients with lupus nephritis who have active inflammation or chronic kidney damage is challenging. Studies have shown soluble CD163, which derives from cleavage of the CD163 M2c macrophage receptor and can be quantified in urine, correlates with active lupus nephritis.MethodsWe measured urine CD163 at lupus nephritis flares in patients from a Mexican cohort and cross-sectional and longitudinal United States cohorts. We also performed serial urine CD163 measurements during the treatment of flares in a subset of patients from the Mexican and longitudinal United States cohorts, and assessed response to therapy at 12 months. In addition, we evaluated urinary CD163 agreement with histologic activity in 19 patients from the Mexican cohort who had repeated kidney biopsies on follow-up.ResultsUrinary CD163 levels were significantly higher in patients with active lupus nephritis than in patients with active extrarenal SLE, inactive SLE, and other glomerular diseases, and correlated with disease clinical severity, histologic class, and the histologic activity index. Urinary CD163 increased from 6 months preflare to flare, diminishing progressively in complete and partial responders, whereas it remained elevated in nonresponders. Urinary CD163 <370 ng/mmol at 6 months predicted complete renal response at 12 months with >87% sensitivity and >87% specificity. Urinary CD163 <370 ng/mmol or >370 ng/mmol perfectly agreed (κ=1.0) with a histologic activity index ≤1 or >1 in repeated biopsies, respectively. Evaluation of urinary CD163 in patients with persistent proteinuria at 6 months improved the prediction of who would achieve complete renal response at 12 months.ConclusionsUrinary CD163 reflects histologic inflammation in lupus nephritis and is a promising activity biomarker that varies over time with lupus nephritis activity and treatment.

THE AIM: to evaluate the effect of allelic variations in the hemostatic system genes on the development and course of lupus nephritis. PATIENTS AND METHODS. The study analyzed 100 patients with SLE Caucasians. 80 women and 20 men aged 16 to 73 years (mean age 37, ± 14 years). The duration of observation was for 73 patients over 5 years, for 18 – from 1 year to 5 years and for 9 – less than 1 year A rise in the level of creatinine in the blood above or equal to 2 mg / dl was considered a significant sign of impaired renal function. RESULTS. Among the patients included in the study, kidney damage was detected in 61 people (61%). In 33 of them (54.1%), a variant of renal pathology was observed according to the type of rapidly progressive lupus nephritis (BPVN). In patients with BH, mutations in the MTHFR (C677T) gene were statistically significantly more frequent (p = 0.033). The OR for the mutant genotype is 6.146 with 95% CI from 1.692 to 22.326. In patients with PWHD, mutations in the MTHFR (C677T) gene were statistically significantly more frequent (p = 0.031). The OR for the mutant genotype is 1.625 with 95% CI from 1.034 to 4.771. The five-year renal survival in carriers of the mutant allele of the MTHFR gene (C677T) is statistically significantly lower (72.8%) than in patients without this mutation (81.9%) (p = 0.027). Ten-year renal survival in carriers of the mutant allele of the MTHFR gene (C677T) is statistically significantly less (55.6%) than in patients without this mutation (70.5%) (p = 0.016). In patients with BH, mutations in the PAI-1 gene (4G / 5G 675) were statistically significantly more frequent (p = 0.046). OR for mutant genotype – 1.766 with 95% CI from 1.061 to 4.758. CONCLUSION. The mutant alleles of the MTHFR (C677T) and PAI-1 (4G / 5G 675) genes are likely to be associated with the development of BH. Polymorphism of the MTHFR gene (C677T) is associated with an unfavorable course of HH.

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease. Few biomarkers for SLE have been validated and widely accepted for the laboratory follow-up of inflammatory activity. In SLE patients, with lupus nephritis (LN), complement activation leads to fluctuation of serum C3 and C4 that are frequently used as clinicalm biomarker of disease activity in SLE. Patients and Methods: In this study the number of patients were 37, seven patients were excluded for incomplete data collection, 28 were females ,2 were males. The duration of the study is two years from 2015 to 2017. Patients were considered to have SLE and LN according to American College of Rheumatology (ACR) criteria, and International Society of Nephrology/ Renal Pathology Society (ISN/RPS). All patients were evaluated withm clinical presentation, laboratory investigations. Our patients underwent kidney biopsy according to standard procedure by Kerstin Amann, and their tissue specimens were studied in the laboratory with light microscope (LM) and immunofluorescence microscope reagents. The relationship between the serological markers and immunofluorescence deposits in kidney biopsy of all patients were studied using the statistical analysis of Pearson correlation and single table student's T test. A P value 0.05 was considered statistically significant. Results: The granular pattern of IF deposits was present in all LN patients, and in more than two third of patients these IF deposits presented in glomerular, tubular, and mesangium sites. While less than one third of patients had IF deposits in the mesangium only. There was no statistically significant correlation between serum ANA, anti-dsDNA, and IF deposits of different types. There was significant correlation between serum C3 and C4 hypocomplementemia and IgG immune deposits in kidney biopsy, and there was significant relationship between serum C3 hypocomplementemia and full house immunofluorescence (FHIF) deposits inm kidney biopsy.Conclusions:Immunofluorescence deposits is mainly granular pattern in LN patients. There was no significant association between serum ANA, anti-dsDNA, and immune deposits in kidney tissue. Immunofluorescence deposits of IgG type correlates significantly with serum C3 and C4 hypocomplemetemia, and these immune deposits in association with low complement levels correlates with LN flare. There was significant correlation between C3 hypocomplementemia and FHIF.

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
