- 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.

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.
- Extra-criteria manifestations of antiphospholipid syndrome: Risk assessment and management(2018) RADIN, Massimo; UGOLINI-LOPES, Michelle Remiao; SCIASCIA, Savino; ANDRADE, DanieliObjectives: Extra-criteria manifestations of antiphospholipid syndrome (APS) might impact on prognosis and morbidity of the disease. In this study, we aimed to evaluate a population of patients with primary APS (PAPS) whether the extra-criteria manifestations were more frequently found in subjects with higher adjusted Global APS Score (aGAPSS) values when compared to patients with thrombotic and/or obstetric APS (""criteria"" manifestations) only. Methods: Clinical records were analyzed to retrieve extra-criteria manifestation of APS, cardiovascular risk factors and antiphospholipid antibodies profile. The aGAPSS was calculated by adding the points, as follows: 3 for hyperlipidaemia, 1 for arterial hypertension, 5 for anticardiolipin antibodies IgG/IgM, 4 for anti-beta 2 glycoprotein I IgG/IgM, and 4 for lupus anticoagulant. Results: This retrospective multicenter study included 89 consecutive PAPS [mean age 43.1 (S.D. +/- 12.9), female 67%, 52% arterial and 65% venous]. Twenty-seven patients (30.3%) had a history of livedo, 19 (21.3%) had a history of confirmed thrombocytopenia, 3 (3.4%) had biopsy-proven antiphospholipid antibodies (aPL)-related nephropathy and 3 (3.4%) had a history of valvulopathy. Patients with extra criteria manifestations presented a mean aGAPSS significantly higher [mean 10.30 (S.D. +/- 3.57, range: 4-17) vs mean 8.16 (S.D. +/- 3.52;range: 4-16, p = 0.005). When comparing patients with and without extra-criteria manifestations, the first group had significantly higher incidence of anti-beta 2GPI antibodies positivity (59% and 33%, respectively, p = 0.015), double aPL positivities (53% and 31%, respectively, p = 0.034), cerebrovascular events history (52% and 24%, respectively, p = 0.007) and arterial hypertension (52% and 24%, respectively, p = 0.007). Conclusions: Our results suggest that patients with higher aGAPSS, might be at higher risk for developing extra-criteria manifestations of APS and should therefore undergo a thorough laboratory and instrumental evaluation.
- Short- and Long-Term Outcome of Systemic Lupus Erythematosus Peripheral Neuropathy Bimodal Pattern of Onset and Treatment Response(2021) FARGETTI, Simone; UGOLINI-LOPES, Michelle R.; PASOTO, Sandra G.; SEGURO, Luciana P. C.; SHINJO, Samuel K.; BONFA, Eloisa; BORBA, Eduardo F.Background/Objective: Our aim was to describe the short- and long-term outcome of peripheral neuropathy (PN) attributed exclusively to systemic lupus erythematosus (SLE). Methods: Systemic lupus erythematosus patients with defined PN (clinical and electroneuromyography) were retrospectively evaluated at onset, 1-year, and 5-year follow-up using a standardized electronic chart database that started in 2000. Exclusion criteria were comorbidities, drugs, and infections. Age-, sex-, and disease duration-matched SLE patients without PN were selected as controls. Results: Lupus PN was identified in 38 (1.8%) of 2074 patients, and almost two thirds had PN onset in the first 5 years of SLE (63.2%). Peripheral neuropathy SLE had higher frequencies of cutaneous vasculitis (50% vs 21.1%, p = 0.002), lymphopenia (60.5% vs 36.8%, p = 0.027), anti-Sm (52.6% vs 27.6%, p = 0.013), and higher SLEDAI-2K scores (11.5 +/- 10.5 vs 4.9 +/- 6.7, p < 0.001) compared with controls. The most common type was polyneuropathy (71.1%) with sensory-motor pattern (68.4%). At PN diagnosis, all patients received glucocorticoid and 97.4% started immunosuppressive therapy (50% intravenous cyclophosphamide, 42.1% azathioprine). After 1-year follow-up, 92.1% had a favorable outcome with complete (36.8%) or partial remission (55.2%), in parallel with a decrease in prednisone dose (48.3 +/- 17.9 vs 15.3 +/- 13.4 mg/d, p < 0.001), symptomatic therapy (57.9% vs 29.7%, p = 0.02), and SLEDAI-2K score (11.5 +/- 10.5 vs 1.7 +/- 3.7, p < 0.001). SLEDAI-2K scores were higher in patientswho had PN onsetwith less than 1 year of SLE duration, compared with those with more than 5 years of disease (21.3 +/- 9.1 vs 3.9 +/- 5.3, p < 0.001). Early-PN-onset group had a better response to treatment (complete remission at 1-year follow-up 61.5% vs 25%, p = 0.039). At 5-year follow-up, 89.3% remained with complete/partial remission. Conclusions: Peripheral neuropathy attributed to SLE itself is a rare manifestation with a bimodal pattern, characterized by a predominant early-onset group associated with high disease activity and a higher rate of complete remission, and a late-onset group with low disease activity and a partial therapy response.
