conferenceObject Induction of Lupus Nephritisin in Real Situation: Cyclophosphamide or Mycophenolate Mofetil?(2017) MUNHOZ, Gabriela; LACERDA, Maira; LOPES, Michelle; BORBA, Eduardo Ferreira; SEGURO, Luciana; BONFA, Eloisa- Early proteinuria response: a valid real-life situation predictor of long-term lupus renal outcome in an ethnically diverse group with severe biopsy-proven nephritis?(2017) UGOLINI-LOPES, Michelle R.; SEGURO, Luciana Parente C.; CASTRO, Maite Xavier F.; DAFFRE, Danielle; LOPES, Alex C.; BORBA, Eduardo F.; BONFA, EloisaObjective Two recent important lupus nephritis trials reported that proteinuria was a good predictor of renal outcome in Caucasians, but data on real-life situation, other races and severe nephritis are lacking to substantiate this finding as a simple test to guide clinical practice. The aim of this study was to validate proteinuria as a predictor of long-term renal outcome in real-life situation in a racially diverse group of patients with severe nephritis. Methods Proteinuria, serum creatinine (SCr) and urine red blood cells were assessed at baseline and after 3, 6 and 12 months, as early predictors of long-term renal outcome (SCr <1.5 mg/dL at 7 years), in 94 patients with biopsy-proven lupus nephritis. The parameter performance and cut-off values were computed by receiver operating characteristic curves. Kaplan-Meier curves were used to validate the parameter. Results A proteinuria <0.8 g/24 hours at 12 months was the best single predictor of long-term renal outcome (sensitivity 90%, specificity 78%, positive predictive value 67%, negative predictive value (NPV) 94% and area under the curve 0.86; p<0.001). Addition of other variables to proteinuria such as SCr and haematuria at 12 months did not improve its performance. The proteinuria cut-aft value of <0.8 g/24 hours at 12 months was a good predictor of 7-year renal survival (years free of dialysis) for patients with pure membranous (p=0.005) and proliferative nephritis (p=0.043), as well as black (p=0.002) and white race (p=0.001), anti-dsDNA positive (p=0.001) and anti-dsDNA negative (p=0.04) and male (p=0.028) and female (p=0.003) patients. Conclusion We provided novel evidence that, in a real-life situation, proteinuria at 12 months of follow-up was the single best predictor of renal outcome at 7 years for an ethnically diverse group of patients with severe nephritis and a valid parameter for distinct histological classes, races, genders and anti-dsDNA profiles. The remarkably high NPV obtained reinforces its recommendation as the ideal predictor for clinical practice, since it is of low cost, easy to interpret, non-invasive and widely available.
- Immunogenicity and safety of primary fractional-dose yellow fever vaccine in autoimmune rheumatic diseases(2021) TONACIO, Adriana Coracini; PEDROSA, Tatiana do Nascimento; BORBA, Eduardo Ferreira; AIKAWA, Nadia Emi; PASOTO, Sandra Gofinet; FERREIRA FILHO, Julio Cesar Rente; BARROS, Marilia Mantovani Sampaio; LEON, Elaine Pires; LOMBARDI, Suzete Cleusa Ferreira Spina; MENDRONE JUNIOR, Alfredo; AZEVEDO, Adriana de Souza; SCHWARCZ, Waleska Dias; FULLER, Ricardo; YUKI, Emily Figueiredo Neves; LOPES, Michelle Remiao Ugolini; PEREIRA, Rosa Maria Rodrigues; BARROS, Percival Degrava Sampaio; ANDRADE, Danieli Castro Oliveira de; MEDEIROS-RIBEIRO, Ana Cristina de; MORAES, Julio Cesar Bertacini de; SHINJO, Samuel Katsuyuki; MIOSSI, Renata; DUARTE, Alberto Jose da Silva; LOPES, Marta Heloisa; KALLAS, Esper Georges; SILVA, Clovis Artur Almeida da; BONFA, EloisaBackground Brazil faced a yellow fever(YF) outbreak in 2016-2018 and vaccination was considered for autoimmune rheumatic disease patients(ARD) with low immunosuppression due to YF high mortality. Objective This study aimed to evaluate, prospectively for the first time, the short-term immunogenicity of the fractional YF vaccine(YFV) immunization in ARD patients with low immunossupression. Methods and Results A total of 318 participants(159 ARD and 159 age- and sex-matched healthy controls) were vaccinated with the fractional-dose(one fifth) of 17DD-YFV. All subjects were evaluated at entry(D0), D5, D10, and D30 post-vaccination for clinical/laboratory and disease activity parameters for ARD patients. Post-vaccination seroconversion rate(83.7%vs.96.6%, p = 0.0006) and geometric mean titers(GMT) of neutralizing antibodies[1143.7 (95%CI 1012.3-1292.2) vs.731 (95%CI 593.6-900.2), p< 0.001] were significantly lower in ARD compared to controls. A lower positivity rate of viremia was also identified for ARD patients compared to controls at D5 (53%vs.70%, p = 0.005) and the levels persisted in D10 for patients and reduced for controls(51%vs.19%, p = 0.0001). The viremia was the only variable associated with seroconvertion. No serious adverse events were reported. ARD disease activity parameters remained stable at D30(p>0.05). Conclusion Fractional-dose 17DD-YF vaccine in ARD patients resulted in a high rate of seroconversion rate(> 80%) but lower than controls, with a longer but less intense viremia. This vaccine was immunogenic, safe and did not induce flares in ARD under low immunosuppression and may be indicated in YF outbreak situations and for patients who live or travel to endemic areas.

F.conferenceObject Is Uric Acid Level a Predictor of Long-Term Renal Outcome in Lupus Nephritis?(2017) LOPES, Michelle; GAVINIER, Samara; LEON, Elaine; VIANA, Vilma; BORBA, Eduardo Ferreira; BONFA, Eloisa- Is serum uric acid a predictor of long-term renal outcome in lupus nephritis?(2019) UGOLINI-LOPES, Michelle Remiao; GAVINIER, Samara S.; LEON, Elaine; VIANA, Vilma Trindade; BORBA, Eduardo Ferreira; BONFA, EloisaBackground/objective Recent studies observed an association between increased serum uric acid (SUA) levels and renal damage in lupus. However, the predictive value of UA for the development of long-term renal dysfunction in lupus nephritis (LN) is still unknown. The aim of this study was to evaluate if SUA may be a predictor of long-term renal outcome in LN. Methods Eighty biopsy-proven LN patients > 7 years of follow-up were selected. SUA levels were measured in sera stored at - 70 degrees C. All patients had serum stored from LN baseline, and 32 also had stored serum from 6 and 12 months after LN. Renal outcome was addressed after 7 years of follow-up to determine if SUA could be a predictor of long-term renal outcome. A good long-term renal outcome in 7 years was defined as a creatinine clearance (CrCl) >= 90.0 mL/min/1.73 m(2), and poor if CrCl < 90 mL/min/1.73 m(2). Patients were divided in two groups according to the renal outcome to assess whether SUA levels at different time points of follow-up could differentiate such groups. An ROC curve was plotted to assess accuracy. Results SUA levels at baseline and 6 months were not able to differentiate good from poor long-term renal outcomes in LN (respectively p = 0.37, p = 0.28), but at 12 months (p = 0.02), they could clearly differentiate the two groups. ROC curve (12 months) accuracy was 0.76. SUA cutoff was 6.05 mg/dL (sensitivity = 0.67, specificity = 0.89, positive predictive value = 0.85, negative predictive value = 0.73). Conclusion SUA levels < 6.05 mg/dL at 12 months of follow-up is a predictor of good long-term renal outcome in lupus nephritis.
- Effectiveness of renoprotective approaches for persistent proteinuria in lupus nephritis: more than just immunosuppression(2018) CASTRO, M.; UGOLINI-LOPES, M.; BORBA, E. F.; BONFA, E.; SEGURO, L. P. C.Objective The objective of this study is to evaluate the efficacy of a tightly controlled renoprotective protocol in systemic lupus erythematosus (SLE) patients with persistent proteinuria. Methods Thirteen SLE patients with nephritis and persistent proteinuria (>1 g/24 hours) were included. The protocol consisted of regular clinical evaluations every two weeks to assess blood pressure (BP, target <130/80 mmHg), adherence to therapy, diet and smoking. No change in immunosuppressive drugs was allowed but reduction of glucocorticoid dose was permitted if indicated. Clinical, laboratory and treatment evaluations were performed at baseline and at the end of the study (after three months). Results SLE patients had a mean age of 37.85 +/- 7.68 years and disease duration of 9.85 +/- 7.29 years. At baseline, patients had a mean duration of maintenance therapy of 10.38 +/- 7.56 months, 12 with mycophenolate mofetil (92.3%) and one with azathioprine (7.7%). At least one dose optimization of antihypertensive regimen was required in all patients during the study. Seven patients (53.8%) had BP>130/80mmHg at baseline. At the end, 11 patients (84.6%) achieved stable BP target; 92.3% were using an angiotensin-converting enzyme inhibitor, 53.9% an angiotensin receptor blocker, and 46.2% were using combined therapy. All patients had a significant reduction in proteinuria levels (2.26 +/- 1.09 vs 0.88 +/- 0.54 g/24 hours, p < 0.001) and 61.5% achieved proteinuria <1 g/24 hours. A significant decrease in mean prednisone dose was observed (10.96 +/- 6.73 vs 5.38 +/- 3.36 mg/day, p = 0.013) as well as mean Systemic Lupus Erythematosus Disease Activity Index score (4.38 +/- 0.72 vs 3.08 +/- 1.86, p = 0.043). No significant changes were identified in serum creatinine, albumin, potassium, complement 3 and complement 4 levels (p > 0.05). Conclusion This study provides evidence that a tightly controlled renoprotective protocol is effective in reducing persistent proteinuria in lupus nephritis. The concomitant reduction of prednisone without any change in immunosuppression reinforces the importance of strategies beyond the treatment of nephritis activity.
