Background:Optimal prognostic predictors in lupus nephritis (LN) are still not clearly defined. Studies have recently shown that albumin-to-globulin ratio (A/G) is not only a good predictor of outcomes in malignancy, infection and renal disease, but is also a potential marker of increased immunoglobulin synthesis and LN activity and might be useful as a predictor of the development of LN in SLE patients. Studies on the role of A/G in predicting outcomes in LN are, however, lacking.Objectives:To assess a potential prognostic value of A/G at renal biopsy in predicting outcomes in LN.Methods:In this retrospective study we analyzed the demographic, histologic, laboratory and clinical characteristics of patients with biopsy-proven LN diagnosed between 2011 and 2020. All patients met the 1997 revised American College of Rheumatology classification criteria for SLE. Complete remission was defined as proteinuria <0.5 g/day and serum creatinine within 10% from baseline, and partial remission as more than 50% reduction in proteinuria to sub-nephrotic levels and serum creatinine within 10% from baseline.Results:We have included 55 patients (80% women) with biopsy-proven LN (age at biopsy 38±13 years). On renal histology, one patient was class I LN, two patients were class II, 7 were class III, 5 were class III+V, 23 were class IV, two were class IV+V, 11 class VI and 4 had other features. Median eGFR and proteinuria at biopsy were 69 (IQR: 44, 100) mL/min/1.73 m2 and 3.5 (2.3, 5.6) g/day, respectively. Baseline mean A/G was 1.12±0.29 and did not differ between LN classes (p=0.91). At one-year follow-up eGFR increased non-significantly (69 vs. 82 mL/min/1.73 m2, p=0.13) and proteinuria decreased (3.5 vs. 0.6 g/day, p<0.001). Eighteen patients achieved complete remission (CR), 16 partial remission and 21 did not achieve remission. None progressed to ESRD and two patients died, both from sepsis. A/G at the time of biopsy did not differ between group which achieved CR/PR vs. no remission (p>0.05; Figure 1) and was not a significant predictor of remission in a multivariate regression model (OR 5.9, 95% CI 0.6, 63.2).Conclusion:While being a potential marker for transition of SLE to LN, A/G was not showed to be a predictor of renal remission in LN.References:[1]Liu XR, et al.

Background:A number of blood count parameters are associated with inflammatory and autoimmune diseases. There is discordant evidence whether neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and mean platelet volume (MPV) might reflect inflammatory response and have prognostic value in SLE patients. However, the studies examining the potential role of these markers in LN are missing.Objectives:To examine NLR, PLR and MPV at the time of biopsy in patients with LN and evaluate their association with prognosis.Methods:In this retrospective study we analyzed the demographic, histologic, laboratory and clinical characteristics of patients with biopsy-proven LN diagnosed between 2011 and 2020. All patients met the 1997 revised American College of Rheumatology classification criteria for SLE.

On renal histology, one patient was class I LN, two patients were class II, 7 were class III, 5 were class III+V, 23 were class IV, two were class IV+V, 11 class VI and 4 had other features. Median baseline NLR was 3.64 (IQR: 1.85, 6.93), PLR was 167 (IQR: 116, 300) and MPV was 10.0 (IQR: 9.2, 10.8). There were no differences in any of the three parameters between different classess of LN (all p>0.05). Eighteen patients achieved complete remission (CR), 16 partial remission and 21 did not achieve remission. None progressed to ESRD and two patients died, both from sepsis. There no differences in NLR, PLR and MPV at the time of biopsy between group which achieved CR/PR vs. no remission (all p>0.05; Figure 1). We constructed a thorough multivariate regression model which showed that neither NLR, PLR or MPV are predictors of renal remission in LN.Conclusion:NLR, PLR and MPV are not useful prognostic markers in predicting renal remission in LN.References:[1]Hartmann LT, et al.

Abstract Background and Aims Lupus nephritis (LN) poses a considerable impact on the morbidity and mortality of SLE patients. Long term comparative outcome data with cyclophosphamide (CYP) and mycophenolate mofetil (MMF) based regimen from the Indian subcontinent is sparse. We assessed the renal and patient survival of these patients for the types of induction CYP or MMF and the two maintenance therapies – MMF or Azathioprine. We determined the predictors of death and dialysis dependency in the study population. Method In this retrospective study, we analysed outcomes of 100 LN patients, total 67 (26 class III, 25 class IV, 6 class III+V, and 10 class IV+V)) treated with CYP (euro lupus-40 and NIH- Dharmendra Bhadauria 27), and 33 with MMF based regimen with the steroid between July 2008 to June 2018. The class distribution of the patients in the two groups was similar. The data were archived regarding demography, clinical, histopathological features, and the treatment given of all 100 biopsy-proven LN patients. Outcomes between two regimens CYP and MMF in terms of remission, dialysis dependency, and patient survival were compared. The renal survival and patient survival at the end of follow-up between two groups were also analysed. Results The clinical characteristics were similar in both groups, except the activity index was high in CYP patients (6.13 ±4.48 Vs. 4.61 ± 2.80); however, the chronicity index was similar. The overall remission was 70% at the end of induction. The CR, PR, and NR in the CYP group was 46.2%, 23.9 %, 29.9% respectively; however, in the MMF group was 57.6%, 12.1%, and 30.3%, respectively. More patients died in CYP (14.9%) than those in MMF (9.1 %) patients. The 1-, 2-, 3-, 4-, 5- and 10-years patient survival in the CYP induction was 89.5%, 86.2%, 86.2%,83.8%, 83.8% and 83.8% however in MMF was 93.9%, 93.9%, 89%, 89%, 89% and 89% respectively. The most common cause of death was sepsis 9/13(69.2%), followed by uremia. The high serum creatinine, low Hb, male, thrombocytopenia, microscopic haematuria, leukocyturia, nephrotic proteinuria, lack of remission in 12 months, dialysis, doubling of creatinine on follow-up were significant predictors of mortality. The 1-, 2- 3-, 4-, 5- and 10- years renal survival (event death-censored, but dialysis dependency) in CP group was 98.5%, 96.7%, 94.7%, 92.4%, 92.4% and 84 % respectively however in the MMF was 96.8 %, 96.8%, 91.9%, 91.9%, 91.9%, and 78.8% respectively. (Figure 1)At the end of the study, dialysis dependency in the MMF group and CYP group was 7.5% and 12.1 %, respectively (NS). In the maintenance therapy, 3/56(5.3%) had to double of creatinine in MMF, and 7/34 (20.5%) in the AZA group (p=0.03). Conclusion Long term outcomes in terms of patient and renal survival of LN patients treated with CP and MMF based induction is similar. Serum creatinine doubling was more with MMF than AZA based maintenance. The majority of death occurred during induction, and sepsis was the most common cause of death.

Introduction Mycophenolate mofetil is an immunosupressive agent used in transplantation and subsequently in a variety of autoimmune conditions. It inhibits both B and T lymphocyte proliferation, and also has nonimmune effects on the kidney. The major experience in systemic lupus erythematosus has focused on proliferative lupus nephritis. Materials and methods In our study we treated 8 female patients having proliferative lupus nefritis with combination therapy of prednisone (1mg/kg body weight) and mycophenolate mofetil (2g per day). Complete remission was defined as a value for urinary protein excretion that was less than 0.5g per 24 hours, with normal urinary sediment, a normal serum albumin concentration and improved or stable serum creatinine. Partial remission was defined as a daily proteinuria below 2g in the previosly nephrotic patient or minimum 30% from starting values, with normal urinary sediment, serum albumin of minimum 30g/L and stable serum creatinine. Results Two patients had a complete remission after 7 and 2 months respectively. Five patients had a partial remission after 5.2?4.3 months of therapy. One patient did not react to therapy. There were no side effects during the course of therapy. Discussion Considering the fact that 7/8 patients have had nephrotic range proteinuria and that 50% of patients were refractory on standard induction therapy, the results of this study are a good indicator of value of mycophenolate mofetil in the therapy of proliferative forms of lupus nephritis. Conclusion Mycophenolate mofetil has satisfactory results in the treatment of proliferative forms of lupus nephritis with minimal side effects.

Abstract Background and Aims Lupus Nephritis (LN) occurs in up to 80% of children with SLE and it affects the long term outcome and the overall survival. Achieving and maintaining renal remission is crucial. However definition of remission in children is not clearly defined. We compared the outcomes using different published definitions of complete and partial remission. Method 248 children with biopsy proven LN class III or higher (ISN/RPS) diagnosed and treated in 23 international centers in the last 10 years were included. Data regarding their renal outcome were collected for twenty-four months after the start of induction therapy. We applied seven definitions of remission to compare the number of children achieving partial and complete remission. Definitions applied have been adapted from the Bristol-Myers Squibb (BMS) trial, the American College of Rheumatology (ACR) recommendations, the Lupus Nephritis Assesment with Rituximab (LUNAR) trial, the Aspreva Lupus Management Study (ALMS) trial, the Abatacept and Cyclophosphamide Combination: Efficacy and Safety Study (ACCESS) trial, the Kidney Disease Improving Global outcomes (KDIGO) guidelines and the Two-Year, Randomized, Controlled Trial of Belimumab in Lupus Nephritis (BLISS-LN). We also focused on the BMS trial, the ACCESS trial and the KDIGO guidelines definitions to analyse the importance of gender, age, ethnicity and the economic income of the country (as defined by the World Bank) where patients had been treated. Results The mean age at diagnosis was 11 years and 4 month. 71.4% were females. They were mainly East-Asian (34.3%), South-Asian (24.6%) and Caucasian (18.6%). 42.7 % were from middle income countries and 57.3% high income countries. The kidney biopsies showed LN class III in 35.5%; class IV in 45.6% and class V in 18.9%. The different definitions varied significantly in terms of outcomes, with that of the ACCESS trial having the highest percentages of complete remission and the BMS trial the lowest (Figure 1). A relatively small percentage of children achieved partial remission during the follow-up for all the definitions (Figure 2). Focusing on the BMS, ACCESS and KDIGO definitions, we found no statistically significant differences of gender and age in the rate of children entering complete remission at 6, 12 and 24 months. East Asian children did however achieve remission more often than other ethnic groups (p &lt; 0.05) (Figure 3). Children treated in high income countries showed a statistically significant higher percentage of complete remission at 12 and 24 months (p &lt; 0.05) (Figure 4). Conclusion Rate of complete and partial remission varied considerably when using the different definitions. Ethnicity and income of the country where the patients were treated did influence outcome. The findings of our study can help in deciding how to define remission in urgently needed future treatment studies in children.

Introduction Systemic lupus erythematosus affects 4.8–78.5 people per 100,000 worldwide, 90% of whom are females. Geography and ethnicity have been shown to significantly affect the prevalence and natural history of the disease. Lupus nephritis affects around half of patients with systemic lupus erythematosus. Data about systemic lupus erythematosus and lupus nephritis in the Middle East are still scarce. In this study, we aimed to describe the characteristics of systemic lupus erythematosus and lupus nephritis at a tertiary care center in Lebanon. Methods This is a retrospective chart review of all biopsy-proven lupus nephritis patients admitted to the American University of Beirut medical center between January 2000 and December 2018. Patients above 12 years of age who had any International Society of Nephrology/Renal Pathology Society (ISN/RPS) class of lupus nephritis on their renal biopsy were included in the study. Results The study included 55 patients with lupus nephritis. Upon presentation of systemic lupus erythematosus, the most common clinical feature was arthritis, seen in 83% of patients, followed by anemia (82%) and malar rash (48%). In total 93% had positive ANA, 89% had positive anti-dsDNA and 98% of patients had proteinuria. The most common ISN/RPS class of lupus nephritis in our series was IV (49%). At the time of the biopsy 15% of patients underwent dialysis. At 6 months, 11/27 had complete remission, 6/27 had partial remission and 10/27 had no remission. At 1 year, 8/23 had complete remission, 4/23 had partial remission and 11/23 had no remission. During the study period, 15 out of 35 patients available for analysis had chronic kidney disease (CKD) and six out of 34 patients developed end-stage kidney disease requiring renal replacement therapy. In comparison to other series in the region, our series had more males affected, higher creatinine at the time of biopsy and greater degree of proteinuria. Conclusion Our study provided insight on the demographics, characteristics, and outcomes of lupus nephritis in Lebanon. Interestingly, male gender was present in a quarter of patients. This warrants further investigation and confirmation. We are hoping to expand this experience into a national prospective registry to further characterize this entity in our region.

Abstract Background To evaluate histological active and chronic lesions associated with proteinuria and serum creatinine (SCr) level as common clinical endpoints in many clinical trials for lupus nephritis (LN). Methods One hundred and nineteen patients from 1990 to 2015 with LN class III, IV, and V, as defined by the International Society of Nephrology/Renal Pathology Society classification, were enrolled. Multiple regression analysis was performed to explore semiquantitative histological variables related to urinary protein and SCr levels. Results The mean age of enrolled patients was 45 years and 79% were female. The mean SCr level was 0.87 mg/dl and mean urinary protein was 3.00 g/gCr at the time of the renal biopsy. Class IV (71%) was the most common type, followed by class III (17%) and class V (13%). Multicollinearity was confirmed between monocellular infiltration (variance inflation factor [VIF] = 10.22) and interstitial fibrosis (VIF = 10.29) and between karyorrhexis (VIF = 4.14) and fibrinoid necrosis (VIF = 4.29). After excluding fibrinoid necrosis and monocellular infiltration because of multicollinearity, only urinary protein level was correlated with wire loop (β−coefficient [β]: 1.09 and confidence interval [CI]: 0.35 to 1.83), and SCr level was correlated with glomerular sclerosis (β: 1.08 and CI: 0.43 to 1.74) by multiple regression analysis. Conclusion As urinary protein and SCr levels could not reflect active lesions quantitatively, they might be difficult to be evaluated for response to induction remission treatments in patients with LN.

We investigated renal outcome of kidney-transplantation in 19 Korean recipients with biopsy-proven lupus nephritis and compared it with 18 Korean age- and gender-matched recipients without lupus nephritis who were diagnosed with end-stage renal disease caused by renal diseases other than lupus nephritis in a single centre. We reviewed histological findings of kidneys and calculated cumulative dose of immunosuppressive agents. We assessed renal flare of systemic lupus erythematosus, recurrence of lupus nephritis and graft failure as prognosis. The mean age of recipients with lupus nephritis was 43.5 years and all patients were female. Six patients had class III, 10 had class IV and three had class V. There were no meaningful differences in demographic data, renal replacement modality, cumulative doses of immunosuppressants and prognosis between recipients with and without lupus nephritis. Eight patients experienced renal flare of systemic lupus erythematosus, but there were no cases of recurrence of lupus nephritis or graft failure in recipients with lupus nephritis. Kidney-recipients with class IV lupus nephritis exhibited a lower cumulative renal flare of systemic lupus erythematosus free survival rate than those with class III lupus nephritis. In conclusion, renal outcome of kidney-transplantation in patients with lupus nephritis is similar to that in those without lupus nephritis, and class IV was associated with renal flare of systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by aberrant T cell immune response. Diffuse proliferative lupus nephritis (LN-IV) is the most common, severe, and active form of lupus nephritis. In this study, we investigated the production of Th1, Th2, and Th17 cytokines in prediction of active form of LN-IV. ProcartaPlex multiplex immunoassays panels were used for detection of serum Th1, Th2, and Th17 cytokines profiling. Th1 and Th17 cytokines (IL-18, IFN-γ, IL-12p70, IL-6, and IL-17A) were considerably expressed in the serum of lupus nephritis IV patients in comparison to the healthy control. However, only IL18 and IL6 were higher in class IV versus class III lupus nephritis. Importantly, the ratios of Th1/Th2 (IL-18/IL-4) and Th17/Th2 (IL-17A/IL-4) were significantly elevated in LN-IV when compared with LN-III, LN-V, and healthy controls. Consistently, the serum cytokines IL-18, IL-17A, and IFN-γwere markedly expressed in LN-IV patient glomeruli and interstitial tissue compared to other classes of LN by IHC. ROC further suggests that IL-18 was a potential marker for LN-IV. The data from our study suggests that the early detection and quantification of these cytokines may help in prediction of active form of LN-IV.

AbstractLupus nephritis (LN) is a life-threatening complication of systemic lupus erythematosus. The 2003 pathological classification of LN was revised in 2016; it quantitatively evaluates the interstitium in addition to the glomeruli. We performed a retrospective multi-centre cohort study and investigated the utility of the 2016 classification—including the activity index (AI), chronicity index (CI), and each pathological component to predict complete remission or renal function decline, defined as 1.5-fold increase in serum creatinine levels—and compare with that of the 2003 classification. Ninety-one consecutive adult patients with first-onset class III/IV LN who were newly prescribed any immunosuppressants were enrolled and followed up for a median of 51 months from January 2004. Cox regression analysis demonstrated the subclasses based on the 2003 classification, which mainly evaluate glomerular lesions, were not associated with clinical outcomes. After adjustments for estimated glomerular filtration rate and urinary protein levels, higher CI and higher interstitial fibrosis and lower hyaline deposit scores were associated with renal functional decline. Similarly, higher CI and interstitial inflammation scores were associated with failure to achieve complete remission. Therefore, the 2016 classification can predict the clinical outcomes more precisely than the 2003 classification.
