Abstract
Lupus nephritis (LN) is a frequent and severe manifestation of SLE. Along the decades, the epidemiology of LN and its clinical presentation have been changing. However, even though retrospective cohort studies report a decreased mortality rate and an improvement in the disease prognosis, the percentage of patients progressing into end stage renal disease (ESRD) keeps steady despite the improvements in therapeutic strategies. Current in-use medications have been available for decades now, yet over the years, regimens for optimizing their efficacy and minimizing toxicity have been developed. Therapeutic research is now moving towards the direction of precision medicine and several new drugs, targeting selectively different pathogenetic pathways, are currently under evaluation with promising results. In this review, we address the main changes and persistent unmet needs in LN management throughout the past decades, with a focus on prognosis and upcoming treatments.

Abstract
In November 2017, the Kidney Disease: Improving Global Outcomes (KDIGO) initiative brought a diverse panel of experts in glomerular diseases together to discuss the 2012 KDIGO glomerulonephritis guideline in the context of new developments and insights that had occurred over the years since its publication. During this KDIGO Controversies Conference on Glomerular Diseases, the group examined data on disease pathogenesis, biomarkers, and treatments to identify areas of consensus and areas of controversy. This report summarizes the discussions on primary podocytopathies, lupus nephritis, anti-neutrophil cytoplasmic antibody-associated nephritis, complement-mediated kidney diseases, and monoclonal gammopathies of renal significance.

Abstract
BACKGROUND Epstein Barr virus (EBV)-associated primary central nervous system lymphoma (ePCNSL) is increasingly recognized in immunocompromised subjects, including patients receiving systemic immunosuppressive therapy. Here, we report the first case of primary CNS lymphoma associated with EBV in a patient with diffuse cutaneous systemic sclerosis (dcSSc) receiving long-term mycophenolate mofetil (MMF). CASE REPORT A 51-year-old female with dcSSc had been on MMF 2 grams daily, which was initiated for a rapidly rising modified Rodnan skin score (mRSS), severe pruritus, and progressive joint contractures. She had an impressive response to this therapy with a significant decrease in her mRSS. Her condition remained stable for the next five years, after which she developed worsening headaches for 2-3 weeks, associated with dizziness, gait instability, and left homonymous hemianopia. MRI scan of the brain revealed a solitary 2.4cm peripherally enhancing right parietal lobe mass. Excised tissue from the right parietal lobe mass showed EBV-associated diffuse large B cell lymphoma. She received four cycles of chemotherapy (high dose methotrexate and rituximab). Currently, her condition is being monitored. Her left homonymous hemianopia persists. CONCLUSION Because of a favorable toxicity profile, MMF is increasingly being used as long-term immunomodulatory therapy for a wide variety of autoimmune disorders. Nevertheless, patients on long-term MMF should still undergo regular CNS surveillance, not only for opportunistic infections but also for opportunistic malignancies such as PCNSL. Progressive focal or non-focal neurological deficits should always raise the alarm. Prompt evaluation and management can prevent irreversible neurological sequelae.

Abstract
Renal involvement in systemic lupus erythematosus (SLE) carries substantial morbidity and mortality. Conventional immunosuppressive agents (cyclophosphamide and azathioprine) have suboptimal efficacy and substantial toxicity. Mycophenolate mofetil has emerged as an alternative agent for both induction and maintenance therapy in lupus nephritis because of its reduced gonadal toxicity, despite its failure to demonstrate superiority over cyclophosphamide in pivotal studies. The calcineurin inhibitor tacrolimus has equivalent efficacy to cyclophosphamide and mycophenolate mofetil for inducing remission of lupus nephritis. Although rituximab has shown promise in refractory lupus nephritis, combining rituximab with mycophenolate mofetil as initial therapy offers no additional benefit. Considerable interethnic variation is evident in the efficacy and tolerability of the various immunosuppressive regimens, which necessitates individualized treatment and comparison of the efficacy of new regimens across different ethnic groups. For example, low-dose combinations of tacrolimus and mycophenolate mofetil seem to be more effective than pulse cyclophosphamide as induction therapy in Chinese patients. The same regimen has also been used successfully to treat refractory proliferative and membranous lupus nephritis in patients of various ethnic groups. Finally, novel serum and urinary biomarkers are being validated for diagnosis, prognostic stratification and early recognition of flares in lupus nephritis.

Int J Nephrol 2015; 2015:917567. [PMID: 26600951 PMCID: PMC4639665 DOI: 10.1155/2015/917567] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2015] [Revised: 09/23/2015] [Accepted: 09/29/2015] [Indexed: 12/05/2022] Open
Abstract
Background/Aims. We aimed to examine the cost-effectiveness of mycophenolate mofetil (MMF) and azathioprine (AZA) as maintenance therapy for patients with Class III and Class IV lupus nephritis (LN), from a United States (US) perspective. Methods. Using a Markov model, we conducted a cost-utility analysis from a societal perspective over a lifetime horizon. The modeled population comprised patients with proliferative LN who received maintenance therapy with MMF (2 gm/day) versus AZA (150 mg/day) for 3 years. Risk estimates of clinical events were based on a Cochrane meta-analysis while costs and utilities were retrieved from other published sources. Outcome measures included costs, quality-adjusted life-years (QALY), incremental cost-effectiveness ratios (ICER), and net monetary benefit. Results. The base-case model showed that, compared with AZA strategy, the ICER for MMF was $2,630,592/QALY at 3 years. Over the patients' lifetime, however, the ICER of MMF compared to AZA was $6,454/QALY. Overall, the ICER results from various sensitivity and subgroup analyses did not alter the conclusions of the model simulation. Conclusions. In the short term, an AZA-based regimen confers greater value than MMF for the maintenance therapy of proliferative LN. From a lifelong perspective, however, MMF is cost-effective compared to AZA.

Abstract
We performed a retrospective cohort analysis focusing on lupus nephritis renal flare incidence and outcome predictors. One hundred and eighteen patients with biopsy-proven lupus nephritis were segregated by induction/maintenance regimes. The primary outcome was the proportion of patients experiencing renal flare. Secondary assessment included doubling of serum creatinine and development of end-stage renal disease. After a median follow-up of 31 months (interquartile range 21–46) from the date of response to induction therapy, 47 patients (39.8%) developed a renal flare. Azathioprine-maintained patients had a higher risk of renal flare compared with mycophenolate mofetil-maintained patients (hazard ratio 2.53, 95% confidence interval 1.39–4.59, p < 0.01). Age (hazard ratio 0.96, 0.92–0.99, p = 0.03), serum creatinine at presentation (hazard ratio 1.76, 1.13–2.76, p = 0.01), complete remission after induction therapy (hazard ratio 0.28, 0.14–0.56, p < 0.001) and azathioprine maintenance therapy (hazard ratio 4.78, 2.16–10.6, p < 0.001) were associated with renal flare on multivariate analysis. Ten patients progressed to end-stage renal disease (8.5%) by a median 32.5 months. Age (hazard ratio 0.88, 0.77–0.99, p = 0.05), complete remission after induction therapy (hazard ratio 0.08, 0.01–0.94, p = 0.04) and severe nephritic flare (hazard ratio 13.6, 1.72–107.7, p = 0.01) were associated with end-stage renal disease development. Azathioprine maintenance therapy is associated with a higher incidence of relapse in the Mexican-mestizo population. Younger age and nephritic flares predict development of end-stage renal disease.

Abstract
BACKGROUND Mycophenolate (MF) is effective as a maintenance therapy after induction therapy in patients with lupus nephritis (LN). However, little is known about its role in patients with impaired renal function. The purpose of this study was to evaluate the efficacy and safety of MF as a maintenance therapy for LN and its association with renal function. METHODS Data were obtained for 56 Spanish patients who were receiving MF as a maintenance therapy for LN. Patients were classified into two groups according to renal function at the initiation of MF treatment: group 1 [estimated glomerular filtration rate (eGFR) ≥60 ml/min/1.73 m(2)] and group 2 (eGFR <60 ml/min/1.73 m(2)). The primary endpoints of the study were the rates of renal relapse and responses, and their relationship with baseline renal function. Secondary outcomes were the appearance of side effects during treatment. RESULTS At initiation of MF treatment, the only differences between the groups were for age, hemoglobin levels, anti-DNA antibody titer, proteinuria, and renal function. In group 1 (n = 38), the eGFR was 98 ± 34 ml/min/1.73 m(2) and in group 2 (n = 18) the eGFR was 43 ± 14 ml/min/1.73 m(2). Only 3 cases had an eGFR <30 ml/min/1.73 m(2). No significant differences were observed in the rate of relapse at 6 months (group 1: 20%; group 2: 23%) or at 12 months (group 1: 25%; group 2: 17%). Response rates were also similar in both groups. Side effects were unremarkable. CONCLUSIONS MF is effective and safe as a maintenance therapy for LN both in patients with normal renal function and in those with renal impairment.

Abstract
BACKGROUND In an era of increased emphasis on patient safety and competency-based education, demonstration of significant variability in the teaching of flexible bronchoscopy has led to initiatives for new standardized curricula and assessment tools. OBJECTIVES To evaluate the efficacy of such curricula and to assess bronchoscopic skill, 2 measuring instruments have been developed: the Bronchoscopy Skills and Tasks Assessment Tool (BSTAT) and the Bronchoscopy Step-by-Step Evaluation Tool (BSET). We studied the validity and reliability of these 2 instruments. METHODS Two independent testers simultaneously scored 22 volunteer participants at 3 levels [novice (n = 7), fellow (n = 8) and attending (n = 7)] on a virtual reality bronchoscopy simulator using the 2 instruments; each participant was tested twice, in 2 separate sessions. Intertester and test-retest reliability were analyzed with intraclass correlations (ICC); ANOVA was used to assess concurrent validity based on the subjects' expected skill level. RESULTS The ICCs between the testers were 0.98 for both the BSTAT and BSET. Comparison of the scores between the sessions showed high test-retest reliability by ICC (0.86 and 0.85 for BSTAT and BSET respectively), with a small yet statistically significant learning effect. The novice group's scores were lower than the fellows' and attendings' (p < 0.001) for both the BSTAT and BSET; the fellows' scores were consistently lower than the attendings' on both tests, yet the differences were not statistically significant. CONCLUSION This validation study of 2 objective tests of bronchoscopic skill demonstrated high reliability and concurrent validity. These instruments can now be used to evaluate the effectiveness of new competency-based bronchoscopy curricula.
