Objective To estimate real-life European Alliance of Associations for Rheumatology (EULAR)/European Renal Association (ERA)-European Dialysis and Transplantation Association (EDTA) response rates and predictors for no response in patients with lupus nephritis (LN) managed with conventional immunosuppressive therapies. Methods Ambidirectional cohort study of patients with new-onset LN (period 2014–to date). Response rates in the first year were calculated, and all treatment modifications were recorded. Univariate and multivariate regression analyses were performed to assess determinants of failure to respond at 12 months. Results 140 patients were included (81.4% women, median (IQR) age at LN diagnosis 38 (22) years). Among them, 32.1% presented with nephrotic range proteinuria, 28.6% with glomerular filtration rate <60 mL/min, 76.6% had proliferative and 19.7% class V LN. Initial treatment consisted of cyclophosphamide in 51.4% of patients (84.7% high-dose, 15.3% low-dose) and mycophenolate in 32.1%. 120 patients had available data at 12 months. EULAR/ERA-EDTA renal response rates at 3, 6 and 12 months were achieved by 72.6%, 78.5% % and 69.2% of patients, respectively. In multivariate analysis, increased Chronicity Index at baseline was associated with failure to achieve either complete or partial response at 12 months (OR 2.26, 95% CI 1.35 to 3.77). Notably, 20% of patients required treatment modifications due to suboptimal response during the first 12 months, with the addition of or switch to a different immunosuppressive drug in seven and nine patients, respectively. Conclusions More than two-thirds of patients with LN attain EULAR/ERA-EDTA response rates by 12 months, but 20% require therapy modifications within this time period. Patients with increased chronicity in baseline biopsy, when combined with histological activity, are at higher risk for a lack of clinical response.

Mental disorders such as anxiety and depression are prevalent in systemic lupus erythematosus (SLE) patients, yet their association with the underlying disease activity remains uncertain and has been mostly evaluated at a cross-sectional level. To examine longitudinal trends in anxiety, depression, and lupus activity, a prospective observational study was performed on 40 adult SLE outpatients with active disease (SLE Disease Activity Index [SLEDAI]-2K ≥ 3 [excluding serology]) who received standard-of-care. Anxiety and depression were determined at baseline and 6 months by the Hospital Anxiety and Depression Scale. Treatment adherence was assessed with the Morisky Medication Adherence Scale-4. Increased anxiety (median [interquartile range] HADS-A: 11.0 [7.8]) and depression (HADS-D: 8.0 [4.8]) were found at inclusion, which remained stable and non-improving during follow-up (difference: 0.0 [4.8] and −0.5 [4.0], respectively) despite reduced SLEDAI-2K by 2.0 (4.0) (p < 0.001). Among possible baseline predictors, paid employment—but not disease activity—correlated with reduced HADS-A and HADS-D with corresponding standardized beta-coefficients of −0.35 (p = 0.017) and −0.27 (p = 0.093). Higher anxiety and depression correlated with lower treatment adherence (p = 0.041 and p = 0.088, respectively). These results indicate a high-mental disease burden in active SLE that persists despite disease control and emphasize the need to consider socioeconomic factors as part of comprehensive patient assessment.
