Abstract
Systemic lupus erythematosus mainly affects young women, and approximately half of systemic lupus erythematosus patients develop lupus nephritis (LN). However, data on the types and remission rates of LN in Saudi Arabia are limited. Therefore, we aimed to highlight the LN remission rates in our population. A retrospective record review was conducted between January 2007 and December 2020 in a tertiary center in the western region of Saudi Arabia to determine the remission rates among patients with biopsy-proven LN who met the EULAR\ACR 2019 classification criteria. We identified 59 patients with biopsy-proven LN, mostly in young women. The common histopathological pattern was Class IV LN in 26 patients (44%). Three induction protocols were identified, along with systemic steroids: the high-dose cyclophosphamide protocol in 21 patients (35.6%), low-dose protocol in 4 patients (6.8%), and mycophenolate mofetil (MMF) in 41 patients (69.5%). Partial response, defined as the reduction of the 24-hour proteinuria by 25% at 3 months and 50% at 6 months, was achieved in 18 patients (33.3%) at 3 months and decreased to 13 patients (24.1%) at 6 months. Complete clinical response, defined as 24-hour urinary protein between 500 and 700 mg at 12 months, was achieved in 44 patients (81.5%). Complete remission was higher among patients with Class IV LN (64.4%). The achievement of partial clinical response at 3 months was significantly lower among patients with hypertension (P = .041). This study presented the LN remission rates in a single center in Saudi Arabia. Similar to previous studies, Class IV LN were the most common histopathological finding in this study. Complete remission at 12 months was achieved in 44 (81%) patients. Delayed remission is associated with hypertension at the time of LN diagnosis.

Abstract
Systemic lupus erythematosus (SLE), the prototype of systemic autoimmune diseases is characterized by extreme heterogeneity with a variable clinical course. Renal involvement may be observed and affects the outcome. Hydroxychloroquine should be administered to every lupus patient irrespective of organ involvement. Conventional immunosuppressive therapy includes corticosteroids, methotrexate, cyclophosphamide, mycophenolate mofetil, azathioprine, cyclosporine and tacrolimus. However, despite conventional immunosuppressive treatment, flares occur and broad immunosuppression is accompanied by multiple side effects. Flare occurrence, target organ involvement, side effects of broad immunosuppression and increased knowledge of the pathogenetic mechanisms involved in SLE pathogenesis as well as the availability of biologic agents has led to the application of biologic agents in SLE management. Biologic agents targeting various pathogenetic paths have been applied. B cell targeting agents have been used successfully. Belimumab, a B cell targeting agent, has been approved for the treatment of SLE. Rituximab, an anti-CD20 targeting agent is also used in SLE. Anifrolumab, an interferon I receptor-targeting agent has beneficial effects on SLE. In conclusion, biologic treatment is applied in SLE and should be further evaluated with the aim of a good treatment response and a significant improvement in quality of life.

Abstract
OBJECTIVE A retrospective cohort study was undertaken in a predominantly Black population undergoing standard treatment for lupus nephritis (LN) to estimate the incidence of, and risk factors for, complete response (CR) according to modified Aspreva Lupus Management Study (mALMS) and modified Belimumab International Study in Lupus Nephritis (mBLISS) criteria by 12 months. METHODS Patients with biopsy-proven LN class III or IV ± V, urine protein-to-creatinine ratio of ≥1gm/gm and estimated glomerular filtration rate of >50 ml/minute/1.73 m2 at the time of the incident LN flare were included. The clinical, treatment, and laboratory factors associated with CR were identified using multivariable Cox regression. RESULTS Of 173 patients, 86.1% were women, 77.5% were Black, and over half (59.5%) had non-commercial insurance. By 12 months, 20.6% (95% confidence interval (95% CI) 14.6-28.6%) achieved mALMS CR and 33.7% (95% CI 26.4-42.4%) achieved mBLISS CR. Factors associated with mBLISS CR were commercial insurance (adjusted CR ratio = 3.5 [95% CI 1.9-6.7]; P < 0.001), albumin (adjusted CR ratio = 1.8 per 1 gm/dl increase in albumin; P = 0.02), and low C4 (adjusted CR ratio = 2.6; P = 0.03). Cumulative incidence of end-stage renal disease (ESRD) at 3 years was 23.1% (95% CI 15.7-31.3%) and 6.1% (95% CI 2.8-11.1%) for death. Patients with non-commercial insurance were more likely to develop ESRD, with cumulative incidence of 30.4% (95% CI 19.6-41.9%) compared to 12.7% (95% CI 5.0-24.2%) for patients with commercial insurance (P = 0.024). CONCLUSION In a primarily Black, uninsured LN population, despite achieving similar CR rates at 12 months, the incidence of ESRD and death exceeded those observed in controlled clinical trials with placebo arms.

Abstract
BACKGROUND There is a paradigm shift in the induction therapy for proliferative lupus nephritis (LN). Apart from cyclophosphamide (CYC), mycophenolate mofetil and calcineurin inhibitors have emerged as an alternative option of treatment. OBJECTIVE We aimed to compare the cost-effectiveness analysis (CEA) per year, adverse events and renal damage at 24 months between CYC and non-CYC agents (calcineurin inhibitors or mycophenolate) as induction treatment among proliferative lupus nephritis (LN) patients. METHODS This was a retrospective and non-controlled study involving biopsy-proven proliferative LN patients (class III or IV with or without V) in the clinic registry from 2017 to 2019. Their medical records were reviewed to determine the date and type of induction, treatment effectiveness, adverse events and renal damage at 24 months. The total cost of treatment included capital cost (building, furniture and equipment) and recurrent cost (emolument, supply/drug, lab investigations, administrative cost and utilities). Treatment effectiveness was defined as renal remission (partial or complete) at 6 months without relapse up to 24 months. The cost-effectiveness analysis (CEA) was expressed as cost per remission per year in Malaysian Ringgit (MYR). RESULTS There were a total of 95 inductions with CYC and 27 with non-CYC in 94 LN patients. There was no significant difference in the total mean cost per patient/year between CYC (MYR 18460.26 ± 6500.76) compared to non-CYC (MYR 19302.10 ± 6778.22), p = 0.569. The CEA for CYC was MYR 20,632.06 (GBP 3,538.78) while non-CYC was MYR 20,846.27 (GBP 3,575.52) and mean difference MYR 214.21 (GBP 37.44). There was significantly higher capital cost, consumables, utility, maintenance, administration (p < 0.001) and lab investigations (p = 0.046) in the CYC arm. There was a trend of a higher infection requiring outpatient antibiotic treatment in CYC group (p = 0.05), but similar renal damage outcome with the non-CYC group.Conclusion: For treatment of proliferative LN, there was no significant difference in the CEA and renal damage between CYC and non-CYC induction treatment. There was a trend of a higher rate of infections in the CYC group. Hence, the decision to treat patient with CYC or MMF should be tailored to individual patients, by considering the risk of infection in a particular patient.

Abstract
INTRODUCTION/OBJECTIVES Lupus nephritis (LN) is a major and serious complication of systemic lupus erythematosus (SLE) and is associated with morbidity and mortality. The difference in drug cost between mycophenolate mofetil (MMF) and cyclophosphamide (CYC) inducing regimens becomes a relevant and realistic issue, especially in developing countries. Thus, this study aims to estimate and compare the costs and outcomes of CYC and MMF for better allocation of resources to reduce the burden on the Egyptian healthcare system. METHODS A prospective, parallel observational study was conducted at Kasr Al-Aini Hospital between 2018 and 2020. One hundred and twenty-two LN patients were followed up monthly during the study period. Remission and maintenance of renal remission were assessed at 6 and 12 months from the start of therapy. Total direct medical costs associated with both regimens were examined. We applied the cost-minimization analysis method from governmental perspective. Besides, a prospective evaluation of reported changes in health-related quality of life using SF-36 was included in our study. RESULTS There was no statistically significant difference in treatment response at 6 and 12 months (RR 0.6 [0.26;1.43] and 0.8 [0.27;2.33]), respectively, as well as the incidence of infection episodes between MMF and CYC group (71.4% versus 70.45%, p > 0.05). The average direct medical expenditures per patient in the MMF group were approximately one and half times more than the CYC group (2339.69 $ versus 1329.03 $, p <0.001). CONCLUSION The CYC arm was associated with lower costs than the MMF arm, with equally effective outcomes indicating that CYC is an attractive treatment option.

Abstract
OBJECTIVES To demonstrate the significance of the time to attain lupus low disease activity state (LLDAS) after remission induction therapy in patients with severely active systemic lupus erythematosus (SLE). METHODS We enrolled 79 patients starting prednisolone ≥0.4 mg/kg/day for active lupus with a British Isles Lupus Assessment Group 2004 index of A ≥ 1 or B ≥ 2, or for severe flare based on the Safety of Estrogens in Lupus Erythematosus National Assessment-SLE Disease Activity Index (SELENA-SLEDAI). The time to LLDAS attainment was divided into ≤6, 6-12, and >12 months and non-LLDAS; associations between the timing of LLDAS and flares, damage accrual, and ≥50% LLDAS attainment were examined. RESULTS The mean SLEDAI was 17; median starting dose of prednisolone, 0.95 mg/kg/day; and mean observational period, 39.7 months. Six (7.6%) and 41 (51.9%) patients achieved LLDAS within 6 and 12 months. Patients with a shorter time to LLDAS achievement were more likely to spend ≥50% of the time in LLDAS and had a lower cumulative prednisolone dose; no differences were observed in damage accrual. Patients requiring longer than 12 months to achieve LLDAS had a higher prevalence of thrombocytopenia and those with non-LLDAS had lower renal function and a higher starting dose of prednisolone and steroid pulse therapy than those who achieved LLDAS within 12 months. CONCLUSION Achieving LLDAS within 12 months of induction therapy may be favourable in patients with severely active SLE. The low frequency of LLDAS attainment in high-risk populations highlights the need for a new strategy for SLE treatment.

Abstract
OBJECTIVE The effectiveness and safety of sirolimus for SLE treatment have been shown in some uncontrolled studies. However, a comparison of sirolimus with other classic immunosuppressants has not been reported. We conducted the study to compare the effectiveness and safety of sirolimus versus tacrolimus for SLE treatment. METHODS A real-world cohort study was conducted. Patients with clinically active SLE who were prescribed sirolimus or tacrolimus were enrolled. Propensity score matching was used to ensure equivalent disease conditions and background medications. SLE disease activity indices, serological parameters, steroid doses, modification of other immunosuppressants, renal effectiveness and adverse events were compared between the two groups at 3-month, 6-month, 9-month and 12-month follow-up visits. RESULTS Data from 52 patients in each of the sirolimus and tacrolimus groups were analysed. Indices regarding the effectiveness of sirolimus, including Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) scores, physician's global assessment (PhGA) scores, and proportion of patients with SLEDAI-2K reduction of ≥4 and PhGA increase of <0.3, were equivalent to those of tacrolimus at all follow-up timepoints (all p≥0.05). Greater improvements in complement levels were observed in the sirolimus group at 3 and 6 months. Higher percentages of patients with prednisone doses ≤7.5 mg/day were observed in the sirolimus group at all timepoints. Seventeen adverse events in the sirolimus group were recorded. None was severe or led to drug discontinuation. CONCLUSIONS Overall, sirolimus was as effective as tacrolimus in the treatment of SLE. Sirolimus had better effects on serological improvement and glucocorticoid tapering. Sirolimus was well tolerated in patients with SLE.

Abstract
Glioblastoma multiforme (GBM) is a highly malignant primary brain tumor. The current standard of care for GBM is the Stupp protocol which includes surgical resection, followed by radiotherapy concomitant with the DNA alkylator temozolomide; however, survival under this treatment regimen is an abysmal 12-18 months. New and emerging treatments include the application of a physical device, non-invasive 'tumor treating fields' (TTFs), including its concomitant use with standard of care; and varied vaccines and immunotherapeutics being trialed. Some of these approaches have extended life by a few months over standard of care, but in some cases are only available for a minority of GBM patients. Extensive activity is also underway to repurpose and reposition therapeutics for GBM, either alone or in combination with the standard of care. In this review, we present select molecules that target different pathways and are at various stages of clinical translation as case studies to illustrate the rationale for their repurposing-repositioning and potential clinical use.

Abstract
Objective: To provide real-world data and summarize current clinical evidence on the efficacy and safety of sirolimus in active systemic lupus erythematosus (SLE) patients. Methods: This was a prospective real-world clinical study. Included SLE patients should have Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) ⩾ 2. They were treated with sirolimus and followed up regularly. The SLEDAI-2K, Physician Global Assessment (PGA), serological activity indices, and remission of organ manifestations were evaluated. We also performed a meta-analysis to integrate current evidence of sirolimus in SLE. Results: A total of 49 patients were included in the final analysis. After treatment, the SLEDAI-2K (6.2 ± 3.1 versus 4.0 ± 3.4, p = 0.001) decreased significantly, and the prednisone dosage was tapered successfully (9.9 ± 8.8 mg/day versus 5.9 ± 4.0 mg/day, p = 0.002). Serological activity indices also improved [complement 3 (C3): 0.690 ± 0.209 g/l versus 0.884 ± 0.219 g/l, p < 0.001; complement 4: 0.105 ± 0.059 g/l versus 0.141 ± 0.069 g/l, p < 0.001; anti-dsDNA antibody, 200 ± 178 IU/ml versus 156 ± 163 IU/ml, p = 0.022]. The remission proportions of arthritis, skin rash, and thrombocytopenia were 100%, 88.8%, and 46.2%, respectively. A total of 41.2% of lupus nephritis (LN) patients achieved renal remission, but the average 24-h urine protein level was not significantly changed. Meta-analysis enrolled five studies with 149 patients included, and revealed similar results regarding the changes of SLEDAI-2K [−3.5 (−5.0, −2.1)], C3 [0.224 (0.136, 0.311) g/l] and daily dosage of prednisone [−12.7 (−19.9, −5.6) mg/day]. Conclusion: Sirolimus might be effective and tolerated in SLE. The role of sirolimus in LN requires further study.

Abstract
BACKGROUND AND OBJECTIVES Resistant lupus nephritis (LN) has been associated with the persistence of long-lived plasma cells. Preliminary studies identified bortezomib as a potential treatment option for patients with refractory LN. The aim of this study was to analyze the efficacy and safety of bortezomib in the treatment of severe refractory LN. METHODS This retrospective study included 12 female patients diagnosed for the first time with class IV or IV/V LN with acute or rapidly progressive kidney injury (n = 11) and/or severe nephrotic syndrome (n = 1) who showed resistance to induction therapy with cyclophosphamide, steroids, mycophenolate, and rituximab, and were treated with either intravenous or subcutaneous bortezomib plus intravenous dexamethasone. RESULTS All patients with acute or rapidly progressive kidney injury showed a significant reduction in both biochemical and immunological activity after a mean of 6 (minimum 5, maximum 7) weekly cycles of bortezomib regimen, with a significant increase in C3 levels and a significant decrease of anti-ds DNA antibody titers, Systemic Lupus Erythematosus Disease Activity Index score, serum creatinine, and proteinuria. One patient (8.3%) achieved a complete response, and 10 patients (83.4%) achieved a partial response. During follow-up, all these patients maintained partial responses under treatment with mycophenolate and low-dose glucocorticoids. The patient with refractory nephrotic syndrome showed a partial response but relapsed 11 months after the end of bortezomib treatment and was resistant to treatment. A significant decrease in serum IgG levels after initiation of bortezomib treatment was observed in all patients, five of them (41.6%) showed hypogammaglobulinemia (<500 mg/dl), but no patient suffered from opportunistic infections; in only two patients (16.6%) hypogammaglobulinemia persisted at the end of follow-up. Two patients (16.6%) suffered from sensory neuropathy, which led to bortezomib treatment discontinuation. CONCLUSIONS Bortezomib may be an effective option for refractory LN, but close monitoring must be performed for possible adverse events such as peripheral neuropathy and hypogammaglobulinemia.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the presence of autoantibodies against nuclear antigens, immune complex deposition, and tissue damage in the kidneys, skin, heart and lung. Because of the pathogenic role of antinuclear antibodies and autoreactive T cells in SLE, extensive efforts have been made to demonstrate how B cells act as antibody-producing or as antigen-presenting cells that can prime autoreactive T cell activation. With the discovery of new innate immune cells and inflammatory mediators, innate immunity is emerging as a key player in disease pathologies. Recent work over the last decade has highlighted the importance of innate immune cells and molecules in promoting and potentiating SLE. In this review, we discuss recent evidence of the involvement of different innate immune cells and pathways in the pathogenesis of SLE. We also discuss new therapeutics targets directed against innate immune components as potential novel therapies in SLE.

Abstract
BACKGROUND AND OBJECTIVES Incomplete peripheral blood B cell depletion after rituximab in lupus nephritis might correlate with inability to reduce tubulointerstitial lymphoid aggregates in the kidney, which together could be responsible for inadequate response to treatment. We utilized data from the Lupus Nephritis Assessment with Rituximab (LUNAR) study to characterize the variability of peripheral blood B cell depletion after rituximab and assess its association with complete response in patients with lupus nephritis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We analyzed 68 participants treated with rituximab. Peripheral blood B cell depletion was defined as 0 cells/µl, termed "complete peripheral depletion," assessed over 78 weeks. Logistic regression was used to estimate the association between characteristics of complete peripheral depletion and complete response (defined as urine protein-to-creatinine ratio <0.5 mg/mg, and normal serum creatinine or an increase in creatinine <15%, if normal at baseline), assessed at week 78. RESULTS A total of 53 (78%) participants achieved complete peripheral depletion (0 cells/µl) in a median time of 182 days (interquartile range, 80-339).The median duration of complete peripheral depletion was 71 days (interquartile range, 14-158). Twenty-five (47%) participants with complete peripheral depletion achieved complete response, compared with two (13%) without. Complete peripheral depletion was associated with complete response (unadjusted odds ratio [OR], 5.8; 95% confidence interval [95% CI], 1.2 to 28; P=0.03). Longer time to achieving complete peripheral depletion was associated with a lower likelihood of complete response (unadjusted OR, 0.89; 95% CI, 0.81 to 0.98; P=0.02). Complete peripheral depletion lasting >71 days (the median) was associated with complete response (unadjusted OR, 4.1; 95% CI, 1.5 to 11; P=0.008). CONCLUSIONS There was substantial variability in peripheral blood B cell depletion in patients with lupus nephritis treated with rituximab from the LUNAR trial. Achievement of complete peripheral depletion, as well as the rapidity and duration of complete peripheral depletion, were associated with complete response at week 78.

Abstract
BACKGROUND Cyclophosphamide, in combination with corticosteroids, has been first-line treatment for inducing disease remission for proliferative lupus nephritis, reducing death at five years from over 50% in the 1950s and 1960s to less than 10% in recent years. Several treatment strategies designed to improve remission rates and minimise toxicity have become available. Treatments, including mycophenolate mofetil (MMF) and calcineurin inhibitors, alone and in combination, may have equivalent or improved rates of remission, lower toxicity (less alopecia and ovarian failure) and uncertain effects on death, end-stage kidney disease (ESKD) and infection. This is an update of a Cochrane review first published in 2004 and updated in 2012. OBJECTIVES Our objective was to assess the evidence and evaluate the benefits and harms of different immunosuppressive treatments in people with biopsy-proven lupus nephritis. The following questions relating to management of proliferative lupus nephritis were addressed: 1) Are new immunosuppressive agents superior to or as effective as cyclophosphamide plus corticosteroids? 2) Which agents, dosages, routes of administration and duration of therapy should be used? 3) Which toxicities occur with the different treatment regimens? SEARCH METHODS We searched the Cochrane Kidney and Transplant Specialised Register up to 2 March 2018 with support from the Cochrane Information Specialist using search terms relevant to this review. Studies in the Specialised Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs comparing any immunosuppressive treatment for biopsy-proven class III, IV, V+III and V+VI lupus nephritis in adult or paediatric patients were included. DATA COLLECTION AND ANALYSIS Data were abstracted and the risks of bias were assessed independently by two authors. Dichotomous outcomes were calculated as risk ratio (RR) and measures on continuous scales calculated as mean differences (MD) with 95% confidence intervals (CI). The primary outcomes were death (all causes) and complete disease remission for induction therapy and disease relapse for maintenance therapy. Evidence certainty was determined using GRADE. MAIN RESULTS In this review update, 26 new studies were identified, to include 74 studies involving 5175 participants overall. Twenty-nine studies included children under the age of 18 years with lupus nephritis, however only two studies exclusively examined the treatment of lupus nephritis in patients less than 18 years of age.Induction therapy Sixty-seven studies (4791 participants; median 12 months duration (range 2.5 to 48 months)) reported induction therapy. The effects of all treatment strategies on death (all causes) and ESKD were uncertain (very low certainty evidence) as this outcome occurred very infrequently. Compared with intravenous (IV) cyclophosphamide, MMF may have increased complete disease remission (RR 1.17, 95% CI 0.97 to 1.42; low certainty evidence), although the range of effects includes the possibility of little or no difference.Compared to IV cyclophosphamide, MMF is probably associated with decreased alopecia (RR 0.29, 95% CI 0.19 to 0.46; 170 less (129 less to 194 less) per 1000 people) (moderate certainty evidence), increased diarrhoea (RR 2.42, 95% CI 1.64 to 3.58; 142 more (64 more to 257 more) per 1000 people) (moderate certainty evidence) and may have made little or no difference to major infection (RR 1.02, 95% CI 0.67 to 1.54; 2 less (38 less to 62 more) per 1000 people) (low certainty evidence). It is uncertain if MMF decreased ovarian failure compared to IV cyclophosphamide because the certainty of the evidence was very low (RR 0.36, 95% CI 0.06 to 2.18; 26 less (39 less to 49 more) per 1000 people). Studies were not generally designed to measure ESKD.MMF combined with tacrolimus may have increased complete disease remission (RR 2.38, 95% CI 1.07 to 5.30; 336 more (17 to 1048 more) per 1000 people (low certainty evidence) compared with IV cyclophosphamide, however the effects on alopecia, diarrhoea, ovarian failure, and major infection remain uncertain. Compared to standard of care, the effects of biologics on most outcomes were uncertain because of low to very low certainty of evidence.Maintenance therapyNine studies (767 participants; median 30 months duration (range 6 to 63 months)) reported maintenance therapy. In maintenance therapy, disease relapse is probably increased with azathioprine compared with MMF (RR 1.75, 95% CI 1.20 to 2.55; 114 more (30 to 236 more) per 1000 people (moderate certainty evidence). Multiple other interventions were compared as maintenance therapy, but patient-outcome data were sparse leading to imprecise estimates. AUTHORS' CONCLUSIONS In this review update, studies assessing treatment for proliferative lupus nephritis were not designed to assess death (all causes) or ESKD. MMF may lead to increased complete disease remission compared with IV cyclophosphamide, with an acceptable adverse event profile, although evidence certainty was low and included the possibility of no difference. Calcineurin combined with lower dose MMF may improve induction of disease remission compared with IV cyclophosphamide, but the comparative safety profile of these therapies is uncertain. Azathioprine may increase disease relapse as maintenance therapy compared with MMF.

Abstract
OBJECTIVE This observational study was a retrospective analysis of prospectively collected Hopkins Lupus Cohort data to compare longterm renal survival in patients with lupus nephritis (LN) who achieved complete (CR), partial (PR), or no remission following standard-of-care LN induction therapy. METHODS Eligible patients with biopsy-proven LN (revised American College of Rheumatology or Systemic Lupus Collaborating Clinics criteria) were identified and categorized into ordinal (CR, PR, or no remission) or binary (response or no response) renal remission categories at 24 months post-diagnosis [modified Aspreva Lupus Management Study (mALMS) and modified Belimumab International Lupus Nephritis Study (mBLISS-LN) criteria]. The primary endpoint was longterm renal survival [without endstage renal disease (ESRD) or death]. RESULTS In total, 176 patients met the inclusion criteria. At Month 24 postbiopsy, more patients met mALMS remission criteria (CR = 59.1%, PR = 30.1%) than mBLISS-LN criteria (CR = 40.9%, PR = 16.5%). During subsequent followup, 18 patients developed ESRD or died. Kaplan-Meier plots suggested patients with no remission at Month 24 were more likely than those with PR or CR to develop the outcome using either mALMS (p = 0.0038) and mBLISS-LN (p = 0.0097) criteria for remission. Based on Cox regression models adjusted for key confounders, those in CR according to the mBLISS-LN (HR 0.254, 95% CI 0.082-0.787; p = 0.0176) and mALMS criteria (HR 0.228, 95% CI 0.063-0.828; p = 0.0246) were significantly less likely to experience ESRD/mortality than those not in remission. CONCLUSION Renal remission status at 24 months following LN diagnosis is a significant predictor of longterm renal survival, and a clinically relevant endpoint.

Abstract
The systemic autoimmune/inflammatory condition systemic lupus erythematosus (SLE) manifests before the age of 16 years in 10-20% of all cases. Clinical courses are more severe, and organ complications are more common in patients with juvenile SLE. Varying gender distribution in different age groups and increasing severity with younger age and the presence of monogenic disease in early childhood indicate distinct differences in the pathophysiology of juvenile versus adult-onset SLE. Regardless of these differences, classification criteria and treatment options are identical. In this article, we discuss age-specific pathomechanisms of juvenile-onset SLE, which are currently available and as future treatment options, and propose reclassification of different forms of SLE along the inflammatory spectrum from autoinflammation to autoimmunity.

Abstract
Our previous studies showed that multitarget therapy is superior in efficacy to intravenous cyclophosphamide as an induction treatment for lupus nephritis in Asian populations. We conducted an open label, multicenter study for 18 months as an extension of the prior induction therapy trial in 19 renal centers in China to assess the efficacy and safety of multitarget maintenance therapy in patients who had responded at 24 weeks during the induction phase. Patients who had undergone multitarget induction therapy continued to receive multitarget therapy (tacrolimus, 2-3 mg/d; mycophenolate mofetil, 0.50-0.75 g/d; prednisone, 10 mg/d), and patients who had received intravenous cyclophosphamide induction treatment received azathioprine (2 mg/kg per day) plus prednisone (10 mg/d). We assessed the renal relapse rate during maintenance therapy as the primary outcome. We recruited 116 patients in the multitarget group and 90 patients in the azathioprine group. The multitarget and azathioprine groups had similar cumulative renal relapse rates (5.47% versus 7.62%, respectively; adjusted hazard ratio, 0.82; 95% confidence interval, 0.25 to 2.67; P=0.74), and serum creatinine levels and eGFR remained stable in both groups. The azathioprine group had more adverse events (44.4% versus 16.4% for multitarget therapy; P<0.01), and the multitarget group had a lower withdrawal rate due to adverse events (1.7% versus 8.9% for azathioprine; P=0.02). In conclusion, multitarget therapy as a maintenance treatment for lupus nephritis resulted in a low renal relapse rate and fewer adverse events, suggesting that multitarget therapy is an effective and safe maintenance treatment for patients with lupus nephritis.

Abstract
This review summarizes traditional and emerging therapies for SLE. Evidence suggests that the heterogeneity of SLE is a crucial aspect contributing to the failure of large clinical trials for new targeted therapies. A clearer understanding of the mechanisms driving disease pathogenesis combined with recent advances in medical science are predicted to enable accelerated progress towards improved SLE diagnosis and personalized approaches to treatment.

Abstract
BACKGROUND Childhood-onset lupus nephritis (LN) is one of the most severe manifestations of systemic lupus erythematosus (SLE). Despite treatment-related toxicities, cyclophosphamide (CYC) and glucocorticoid-based treatment protocols are still considered standard therapy in managing this multisystem disorder. An effective and safe alternative induction regimen is needed. METHODS Forty-four pediatric patients with active LN aged 3.5-13.8 (median 8.4) years, of whom 32 entered the study at diagnosis of SLE, were followed over 36 months. Induction therapy consisted of methylprednisolone pulses followed by either rituximab (RTX) (n = 17), mycophenolate mofetil (MMF) (n = 12) or pulse-CYC (n = 15), with tapering dose of prednisolone orally. MMF was added as maintenance immunosuppressant (800 mg/m2 daily) in all children from the third month onward. RESULTS Flare-free survival was significantly higher at 36 months with RTX compared with MMF and CYC (100% for RTX vs. 83% for MMF. and 53% for CYC, p = 0·006). Twelve patients (76.5%) achieved complete remission with RTX compared with five (41.7%) and seven (46.7%) with MMF and CYC, respectively, at last follow-up. Requirement of mean daily dosage of prednisone was significantly lower in RTX group [p = 0.005 (RTX vs MMF); 0.0001 (RTX vs CYC) at 36 months] compared with other groups after the 3-month follow-up. In comparison with few minor adverse events in the other two cohorts, several serious adverse events occurred in the CYC group. CONCLUSIONS Efficacy and medium-term safety of RTX induction followed by MMF maintenance therapy in inducing and maintaining remission among children with LN were evident in this study.

Abstract
Glomerular diseases and renal transplantation are the main fields of nephrology in which the immune system plays a prevalent role. Glomerular diseases have traditionally been attributed to auto-immune conditions, whereas allograft rejection has been considered an allo-immune response. However, common immunopathologic mechanisms that include Toll-like receptors, complement and B-cell activation, as well as genetic and infectious factors appear to be involved in the pathogenesis of both entities. Novel therapeutic regimens directed against specific targets of the immune system show promising results in glomerulopathies as well as in renal transplantation.

Abstract
Abstract
Glomerular diseases and renal transplantation are the main fields in nephrology in which the immune system plays a prevalent role. They have for long been considered as independent conditions due to the prominent role of autoimmunity in glomerular diseases and of alloimmunity in renal transplantation.
Moreover, histologic features differ between glomerular diseases and transplantation: in glomerular diseases, histologic damage involves primarily the glomeruli and secondarily the tubulointerstitium and small vessels, whereas in transplantation, allograft injury comprises primarily the tubulointerstitium and vessels and to a lesser degree the glomeruli.
However, recent research has shown that the pathogenetic mechanisms in both conditions share common pathways and that there is cross-reaction between innate and adaptive immunity as well as between auto- and alloimmunity [1].

Abstract
AIMS The aim of the study was to investigate the combined impact of genetic polymorphisms in key pharmacokinetic genes on plasma concentrations and clinical outcomes of cyclophosphamide (CPA) in Chinese patients with systemic lupus erythematosus (SLE). METHODS One hundred and eighty nine Chinese SLE patients treated with CPA induction therapy (200 mg, every other day) were recruited and adverse reactions were recorded. After 4 weeks induction therapy, 128 lupus nephritis (LN) patients continued to CPA maintenance therapy (200-600 mg week(-1)) for 6 months, and their clinical outcomes were recorded. Blood samples were collected for CYP2C19, CYP2B6, GST and PXR polymorphism analysis, as well as CPA and its active metabolite (4-hydroxycyclophosphamide (4-OH-CPA)) plasma concentration determination. RESULTS Multiple linear regression analysis revealed that CYP2B6 -750 T > C (P < 0.001), -2320 T > C (P < 0.001), 15582C > T (P = 0.017), CYP2C19*2 (P < 0.001) and PXR 66034 T > C (P = 0.028) accounted for 47% of the variation in 4-OH-CPA plasma concentration. Among these variants, CYP2B6 -750 T > C and CYP2C19*2 were selected as the combination genetic marker because these two SNPs contributed the most to the inter-individual variability in 4-OH-CPA concentration, accounting for 23.6% and 21.5% of the variation, respectively. Extensive metabolizers (EMs) (CYP2B6 -750TT, CYP2C19*1*1) had significantly higher median 4-OH-CPA plasma concentrations (34.8, 11.0 and 6.6 ng ml(-1) for EMs, intermediate metabolizers (IMs) and poor metabolizers (PMs), P < 0.0001), higher risks of leukocytopenia (OR = 7.538, 95% CI 2.951, 19.256, P < 0.0001) and gastrointestinal toxicity (OR = 7.579, 95% CI 2.934, 19.578, P < 0.0001), as well as shorter median time to achieve complete remission (13.2, 18.3 and 23.3 weeks for EMs, IMs and PMs, respectively, P = 0.026) in LN patients than PMs (CYP2B6 -750CC, CYP2C19*2*2) and IMs. CONCLUSIONS Our findings have indicated that genetic markers of drug metabolizing enzymes could predict the 4-hydroxylation, adverse reactions and clinical efficacy of CPA. This is a necessary first step towards building clinical tools that will help assess clinical benefit and risk before undergoing CPA treatment in Chinese SLE patients.

Abstract
AIMS This study aimed to assess the relative efficacy and safety of tacrolimus, mycophenolate mofetil (MMF) and cyclophosphamide (CYC) as induction therapy for lupus nephritis. METHODS Randomized controlled trials (RCTs) examining the efficacy and safety of tacrolimus, MMF and CYC for induction therapy in patients with lupus nephritis were included. We performed a Bayesian random-effects network meta-analysis to combine direct and indirect evidence from the RCTs. RESULTS Nine RCTs including 972 patients met the inclusion criteria and pair-wise comparisons were performed, including 11 direct comparisons. Tacrolimus showed a significantly higher overall response rate (complete remission plus partial remission) than CYC (OR 2.35, 95% confidence interval (CI) 1.03-5.45), and was more efficacious than MMF (OR 1.60, 95% CI 0.70-3.57). MMF was superior to CYC in terms of overall response (OR 1.45, 95% CI 0.96-2.42). Ranking probability based on the surface under the cumulative ranking curve (SUCRA) indicated that tacrolimus had the highest probability of being the best treatment for achieving the overall response (SUCRA = 0.9321), followed by MMF (SUCRA = 0.5385) and CYC (SUCRA = 0.0294). In terms of safety, tacrolimus showed the highest probability of decreasing the risk of serious infections (SUCRA = 0.9253), followed by MMF (SUCRA = 0.4027) and CYC (SUCRA = 0.1720). CONCLUSIONS Tacrolimus was the most efficacious induction treatment for patients with lupus nephritis, and had the highest probability of decreasing the risk of serious infections. Higher remission rates combined with a more favorable safety profile suggest that MMF is superior to CYC as induction treatment in these patients.

Abstract
Objective To identify factors associated with clinical outcome in patients with lupus nephritis. Methods Data from the Aspreva Lupus Management Study (ALMS) were analysed. Using multivariate analysis, we assessed the prognostic value of demographic, clinical, laboratory and histopathological features on the frequency of either complete remission (CR) or treatment failure (TF) during the maintenance phase. Results Among the 370 subjects who entered the trial (complete population), non-Hispanic ethnicity was associated with a higher likelihood of CR (OR=2.0). Several factors were independently associated with a greater likelihood of TF, including: (1) anti-double-stranded DNA (anti-dsDNA) at trial entry (OR=12.7), (2) failure to reduce anti-dsDNA within 8 weeks (OR=2.9) and (3) failure to reduce urine protein:creatinine ratio (UP/C) by ≥25% within 8 weeks (OR=2.6). Among the 227 subjects who entered the maintenance phase (maintenance population), baseline estimated glomerular filtration rate (eGFR) ≥90 mL/min/1.73 m2 was associated with a greater likelihood of CR (OR=2.0), and UP/C >1 at the end of induction was associated with a lower likelihood of CR (OR=0.3). Induction treatment with intravenous cyclophosphamide (IVC) was associated with a lower likelihood of TF (OR=0.5), while lack of treatment with antimalarials (OR=2.4), failure to reduce anti-dsDNA during the first 8 weeks of induction (OR=3.5), failure to reduce UP/C during the first 8 weeks of induction (OR=2.1) and anti-dsDNA positivity at the end of induction (OR=8.3) were independently associated with a greater likelihood of TF. Conclusions This analysis demonstrates that levels of anti-dsDNA and UP/C during induction treatment are independently associated with renal outcome over the ensuing 3 years in both the complete and maintenance populations. Ethnicity is associated with renal outcome in just the complete population, and eGFR, induction treatment and treatment with antimalarials are associated with renal outcome in just the maintenance population.

Abstract
INTRODUCTION Mycophenolate sodium, an enteric-coated tablet (EC-MPS), is as effective and safe as mycophenolate mofetil (MMF) in preventing transplant rejection. EC-MPS and MMF improve the outcome of severe lupus nephritis (LN) and have fewer side effects than pulsed intravenous cyclophosphamide. Blood concentrations of mycophenolic acid (MPA), the active metabolite of EC-MPS, vary between participants despite fixed dosing. Interpatient variability has been studied in transplantation, but not well documented in LN. The relationship between MPA concentration and its clinical effect on LN has not been described. METHODS AND ANALYSIS This is a prospective, open-label, randomised controlled trial. -32 participants with LN who meet the inclusion and exclusion criteria will be randomised into two groups: one receiving a fixed dose of EC-MPS and the second, a dosing regimen that is titrated with therapeutic drug monitoring. Included participants will have blood sampled over a period of 8-12 h on three different occasions. Pharmacokinetic parameters will be calculated using non-compartmental methods. ETHICS AND DISSEMINATION The Human Research and Ethics Committee of the Royal Brisbane Women's Hospital have approved this study. The study is registered with Australian and New Zealand Clinical Trials Registry-ACTRN12611000798965 We planned to present the de-identified information at conferences and publish the results in medical journals. TRIAL REGISTRATION ACTRN12611000798965.

Abstract
AIM The options for long-term maintenance therapy in lupus nephritis (LN) remain controversial. This meta-analysis of randomized controlled trials (RCTs) assessed the prognosis and safety of mycophenolate mofetil (MMF) versus azathioprine (AZA) used as maintenance therapy for lupus nephritis. METHODS The data of Cochrane Library, PubMed, EMBASE were retrieved to search the studies about the RCT studies that compared MMF with AZA used as maintenance therapy for lupus nephritis. We extracted the data reflecting prognosis, which included mortality, end-stage renal failure (ESRF), renal relapse, doubling serum creatinine, and adverse effects, then further analyzed the combined results of data and calculated the relative risk (RR). RESULTS Four RCT studies including 328 patients were enrolled into our meta-analysis. There was no difference between the patients receiving either MMF or AZA for maintenance therapy in preventing relapse, progression to end-stage renal failure, death and doubling of serum creatinine. MMF is not superior to AZA in terms of the risks of infection and gastrointestinal upset, but fewer patients receiving MMF developed leukopenia (RR 0.12; 95% confidence interval (CI), 0.04-0.39; P = 0.0004) and amenorrhoea (RR 0.17; 95% CI, 0.04-0.72; P = 0.02) than those receiving AZA. CONCLUSION The current limited evidence suggests that MMF offers similar prognosis as AZA for maintenance therapy, while MMF appears safer than AZA in the treatment of lupus nephritis.

Abstract
A pooled post-hoc analysis of the phase 3, randomized, placebo-controlled BLISS trials (1684 patients with active systemic lupus erythematosus (SLE)) was performed to evaluate the effect of belimumab on renal parameters in patients with renal involvement at baseline, and to explore whether belimumab offered additional renal benefit to patients receiving mycophenolate mofetil at baseline. In addition to belimumab or placebo, all patients received standard SLE therapy. Patients with severe active lupus nephritis were excluded from the trials. Over 52 weeks, rates of renal flare, renal remission, renal organ disease improvement (assessed by Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index and British Isles Lupus Assessment Group), proteinuria reduction, grade 3/4 proteinuria, and serologic activity favored belimumab, although the between-group differences in most renal outcomes were not significant. Among the 267 patients with renal involvement at baseline, those receiving mycophenolate mofetil or with serologic activity at baseline had greater renal organ disease improvement with belimumab than with placebo. Limitations of this analysis included the small patient numbers and the post-hoc nature of this pooled analysis. The results suggest that belimumab may offer renal benefit in patients with SLE. Further study is warranted in patients with severe active lupus nephritis.

Abstract
Drug repositioning is an innovation stream of pharmaceutical development that offers advantages for drug developers along with safer medicines for patients. Several drugs have been successfully repositioned to a new indication, with the most prominent of them being viagra and thalidomide, which have generated historically high revenues. In line with these developments, most of the recent articles and reviews on repositioning are focused on success stories, leaving behind the challenges that repositioned compounds have on the way to the clinic. Here, I analyze repositioning as a business opportunity for pharmaceutical companies, weighing both challenges and opportunities of repositioning. In addition, I suggest extended profiling as a lower-risk cost-effective repositioning model for pharmaceutical companies and elucidate the novel collaborative business opportunities that help to realize repositioning of shelved and marketed compounds.

Abstract
A number of medications do not have a licence, or label, for use in the paediatric age group nor for the specific indication for which they are being used in children. Over recent years, mycophenolate mofetil has increasingly been used off-label (i.e. off-licence) in adults for a number of indications, including autoimmune conditions; progressively, this wider use has been extended to children. This review summarizes current use of mycophenolate mofetil (MMF) in children, looking at how MMF works, the pharmacokinetics, the clinical conditions for which it is used, the advantages it has when compared with other immunosuppressants and the unresolved issues remaining with use in children. The review aims to focus on off-label use in children so as to identify areas that require further research and investigation. The overall commercial value of MMF is limited because it has now come off patent in adults. Given the increasing knowledge of the pharmacodynamics, pharmacokinetics and pharmacogenomics demonstrating the clinical benefits of MMF, new, formal, investigator-led studies, including trials focusing on the use of MMF in children, would be of immense value.

Abstract
BACKGROUND Cyclophosphamide, in combination with corticosteroids has been used to induce remission in proliferative lupus nephritis, the most common kidney manifestation of the multisystem disease, systemic lupus erythematosus. Cyclophosphamide therapy has reduced mortality from over 70% in the 1950s and 1960s to less than 10% in recent years. Cyclophosphamide combined with corticosteroids preserves kidney function but is only partially effective and may cause ovarian failure, infection and bladder toxicity. Several new agents, including mycophenolate mofetil (MMF), suggest reduced toxicity with equivalent rates of remission. This is an update of a Cochrane review first published in 2004. OBJECTIVES To assess the benefits and harms of different immunosuppressive treatments in biopsy-proven proliferative lupus nephritis. SEARCH METHODS For this update, we searched the Cochrane Renal Group's Specialised Register (up to 15 April 2012) through contact with the Trials' Search Coordinator using search terms relevant to this review. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs comparing any treatments for biopsy-proven lupus nephritis in both adult and paediatric patients with class III, IV, V +III and V +IV lupus nephritis were included. All immunosuppressive treatments were considered. DATA COLLECTION AND ANALYSIS Data were abstracted and quality assessed independently by two authors, with differences resolved by discussion. Dichotomous outcomes were reported as risk ratio (RR) and measurements on continuous scales reported as mean differences (MD) with 95% confidence intervals (CI). MAIN RESULTS We identified 50 RCTs involving 2846 participants. Of these, 45 studies (2559 participants) investigated induction therapy, and six studies (514 participants), considered maintenance therapy.Compared with intravenous (IV) cyclophosphamide, MMF was as effective in achieving stable kidney function (5 studies, 523 participants: RR 1.05, 95% CI 0.94 to 1.18) and complete remission of proteinuria (6 studies, 686 participants: RR 1.16, 95% CI 0.85 to 1.58). No differences in mortality (7 studies, 710 participants: RR 1.02, 95% CI 0.52 to 1.98) or major infection (6 studies, 683 participants: RR 1.11, 95% CI 0.74 to 1.68) were observed. A significant reduction in ovarian failure (2 studies, 498 participants: RR 0.15, 95% CI 0.03 to 0.80) and alopecia (2 studies, 522 participants: RR 0.22, 95% CI 0.06 to 0.86) was observed with MMF. In maintenance therapy, the risk of renal relapse (3 studies, 371 participants: RR 1.83, 95% CI 1.24 to 2.71) was significantly higher with azathioprine compared with MMF. Multiple other interventions were compared but outcome data were relatively sparse. Overall study quality was variable. The internal validity of the design, conduct and analysis of the included RCTs was difficult to assess in some studies because of the omission of important methodological details. No study adequately reported all domains of the risk of bias assessment so that elements of internal bias may be present. AUTHORS' CONCLUSIONS MMF is as effective as cyclophosphamide in inducing remission in lupus nephritis, but is safer with a lower risk of ovarian failure. MMF is more effective than azathioprine in maintenance therapy for preventing relapse with no increase in clinically important side effects. Adequately powered trials with long term follow-up are required to more accurately define the risks and eventual harms of specific treatment regimens.

Abstract
Relapses or flares of systemic lupus erythematosus (SLE) are frequent and observed in 27-66% of patients. SLE flares are defined as an increase in disease activity, in general, requiring alternative treatment or intensification of therapy. A renal flare is indicated by an increase in proteinuria and/or serum creatinine concentration, abnormal urine sediment or a reduction in creatinine clearance rate as a result of active disease. The morbidity associated with renal flares is derived from both the kidney damage due to lupus nephritis and treatment-related toxic effects. Current induction treatment protocols achieve remission in the majority of patients with lupus nephritis; however, few studies focus on treatment interventions for renal flares in these patients. The available data, however, suggest that remission can be induced again in a substantial percentage of patients experiencing a lupus nephritis flare. Lupus nephritis flares are independently associated with an increased risk of deterioration in renal function; prevention of renal flares might, therefore, also decrease long-term morbidity and mortality. Appropriate immunosuppressive maintenance therapy might lead to a decrease in the occurrence of renal and extrarenal flares in patients with SLE, and monitoring for the early detection and treatment of renal flares could improve their outcomes.

Abstract
The safety and efficacy of mycophenolate mofetil (MMF) were evaluated in adolescent patients with systemic lupus erythematosus and active or active/chronic class III–V lupus nephritis. During the 24-week induction phase, patients were randomized to oral MMF (target dose 3.0 g/day) or intravenous cyclophosphamide (IVC) (0.5–1.0 g/m2/month), plus prednisone. Response was defined as a decrease in 24-hour urine protein:creatinine ratio (P:Cr) to <3 in patients with baseline nephrotic range proteinuria, or by ≥50% if subnephrotic baseline proteinuria, and stabilization (±25%) or improvement in serum creatinine. In the 36-month maintenance phase, induction therapy responders were randomized 1:1 to MMF (1.0 g twice daily) or oral azathioprine (AZA) (2 mg/kg/day), plus prednisone. In the induction phase, 10 patients received MMF and 14 received IVC; 15 (62.5%) achieved treatment response (MMF, 7 (70%); IVC, 8/15 (57.1%); p = 0.53, odds ratio (95% confidence interval) 2.0 (0.2, 15.5)). There was a non-statistically significant difference in maintenance of response to MMF (7/8; 87.5%) versus AZA (3/8; 37.5%). Seven patients withdrew (MMF, 2; AZA, 5). During both phases, rates of serious adverse events were similar in both arms. During both phases treatment response with MMF was as effective as the comparator.

Abstract
OBJECTIVE To evaluate clinicopathological features and treatment response in patients with lupus nephritis (LN), comparing the childhood- and late-onset forms of the disease. METHODS We retrospectively analyzed clinical presentation, treatment and evolution in patients diagnosed with LN by renal biopsy between 1999 and 2008. Patients were grouped by age-≤18 years (n = 23); and ≥50 years (n = 13)-and were followed for the first year of treatment. RESULTS The baseline features of the childhood- and late-onset groups, respectively, were as follows: mean age, 15 ± 2 and 54 ± 5 years; female gender, 87% and 92%; hypertension, 87% and 77%; Systemic Lupus Erythematosus Disease Activity Index, 29 ± 9 and 17 ± 7 (p = 0.002); estimated glomerular filtration rate (eGFR), 86 ± 66 and 70 ± 18 ml/min; concurrent SLE/LN diagnosis, 90% and 15% (p < 0.001); crescents on biopsy, 74% and 30% (p = 0.02); activity index on biopsy, 4.8 ± 2.6 and 3.3 ± 1.9 (p = 0.10); and interstitial fibrosis (>10%), 39% and 61% (p = 0.08). Treatment consisted mainly of methylprednisolone, prednisone and intravenous cyclophosphamide, average cumulative doses being similar between the groups. After 12 months of treatment, the eGFR in the younger and older patients was 116 ± 62 and 78 ± 20 ml/min, respectively (p = 0.005). Three of the younger patients progressed to dialysis at 12 months, compared with none of the older patients. CONCLUSION Childhood-onset LN seems to be more severe than is late-onset LN.

Abstract
AIM The optimal maintenance therapy for active diffuse lupus nephritis remains to be established. In this study, we explored the efficacy and safety of tacrolimus for maintaining remission of active lupus nephritis compared to that of azathioprine. METHODS Seventy patients with biopsy-proven lupus nephritis who achieved remission were enrolled in nine nephrology centers in China from 2006 to 2008. Patients were randomized either to tacrolimus plus prednisone (n = 34) or azathioprine plus prednisone (n = 36) for six months. Tacrolimus was titrated to achieve a trough blood concentration of 4-6 ng/mL, and the dosage of azathioprine was 2 mg/kg/d. Prednisone was administered at a dose of 10 mg/d to both groups. The primary outcome was incidence of relapse. Response, clinical parameters and adverse effects were secondary endpoints. RESULTS After six months of therapy, two of the azathioprine-treated patients developed renal relapse compared to none of the tacrolimus-treated patients (p = 0.49; odds ratio, 1.06; 95% CI (0.98, 1.15)). Leucopenia (defined as < 2000 cells per cubic millimeter) was significantly more frequent in the azathioprine group than the tacrolimus group (47% vs. 9%, p < .001). CONCLUSION In conjunction with prednisone, maintenance therapy with tacrolimus and azathioprine has a similar low rate of renal relapse, and the tacrolimus regimen has a more favorable safety profile, with less leucopenia. However, since our study lacked sufficient power, longer follow-up is needed to draw final conclusions.

Abstract
Treatment for systemic lupus erythematosus (SLE) has traditionally been restricted to broad-based immunosuppression, with glucocorticoids being central to care. Recent insights into lupus pathogenesis promise new, selective therapies with more favorable side effect profiles. The best example of this is belimumab, which targets the B cell cytokine BLyS and has now received Food and Drug Administration (FDA) approval for its use in SLE. Strategies targeting other cytokines, such as interleukin 6 (IL-6) and interferon (IFN)-α, are also on the horizon. Blockade of costimulatory interactions between immune cells offers another opportunity for therapeutic intervention, as do small molecule inhibitors that interfere with cell signaling pathways. We review here the current strategies for SLE treatment, with particular focus on therapies now in active pharmaceutical development. We will also discuss new understandings in lupus pathogenesis that may lead to future advances in therapy.

Abstract
BACKGROUND Maintenance therapy, often with azathioprine or mycophenolate mofetil, is required to consolidate remission and prevent relapse after the initial control of lupus nephritis. METHODS We carried out a 36-month, randomized, double-blind, double-dummy, phase 3 study comparing oral mycophenolate mofetil (2 g per day) and oral azathioprine (2 mg per kilogram of body weight per day), plus placebo in each group, in patients who met response criteria during a 6-month induction trial. The study group underwent repeat randomization in a 1:1 ratio. Up to 10 mg of prednisone per day or its equivalent was permitted. The primary efficacy end point was the time to treatment failure, which was defined as death, end-stage renal disease, doubling of the serum creatinine level, renal flare, or rescue therapy for lupus nephritis. Secondary assessments included the time to the individual components of treatment failure and adverse events. RESULTS A total of 227 patients were randomly assigned to maintenance treatment (116 to mycophenolate mofetil and 111 to azathioprine). Mycophenolate mofetil was superior to azathioprine with respect to the primary end point, time to treatment failure (hazard ratio, 0.44; 95% confidence interval, 0.25 to 0.77; P = 0.003), and with respect to time to renal flare and time to rescue therapy (hazard ratio, <1.00; P < 0.05). Observed rates of treatment failure were 16.4% (19 of 116 patients) in the mycophenolate mofetil group and 32.4% (36 of 111) in the azathioprine group. Adverse events, most commonly minor infections and gastrointestinal disorders, occurred in more than 95% of the patients in both groups (P = 0.68). Serious adverse events occurred in 33.3% of patients in the azathioprine group and in 23.5% of those in the mycophenolate mofetil group (P = 0.11), and the rate of withdrawal due to adverse events was higher with azathioprine than with mycophenolate mofetil (39.6% vs. 25.2%, P = 0.02). CONCLUSIONS Mycophenolate mofetil was superior to azathioprine in maintaining a renal response to treatment and in preventing relapse in patients with lupus nephritis who had a response to induction therapy.

Abstract
Debate continues about the optimal treatment modality of lupus nephritis (LN). We compared the efficacy and safety of intravenous cyclophosphamide (CYC) and mycophenolate mofetil (MMF) for LN treatment in Korea. After searching for systemic lupus erythematosus (SLE) patients diagnosed between 1998 and 2007 with the diagnostic code of ICD10, we selected the 71 patients who were treated with CYC or MMF without any other immunosuppressant except systemic steroid. Composite outcome was defined as progression to end-stage renal disease (ESRD) and/or all-cause mortality. The initial manifestations of the CYC group were more severe than those of the MMF group. The mean daily MMF dose was 980 ± 100 mg for 21.67 ± 18.25 months. The mean monthly dose per CYC pulse therapy was 850 ± 30 mg for 17.04 ± 13.15 months. The incidence of composite outcome was 5/20 (25%) in the MMF group and 4/51 (7.8%) in the CYC group. The relative risk (RR) for composite outcome in the CYC group was 0.249 (95% CI for RR: 0.067–0.934, p = 0.039) compared with the MMF group with Cox's hazard proportional analysis. In Kaplan–Meier analysis, the probability of composite outcome was lower in the CYC group than in the MMF group (Log rank test p-value = 0.026). The results of this retrospective study suggest that intravenous CYC therapy may be more efficacious in averting ESRD and death than MMF. These results need to be confirmed in a larger randomized controlled trial.

Abstract
A promising therapeutic approach to reducing inflammation is to inhibit the production of proinflammatory cytokines (e.g., tumor necrosis factor alpha [TNF-α], interleukin 1 beta [IL-1β], vascular endothelial growth factor alpha (VEGF-α), and, as shown more recently, interleukin-17 [IL-17]). In the present study, the authors have demonstrated the anti-inflammatory effects of mycophenolate mofetil (MMF) in in vivo experiments and have investigated the mechanism of action underlying those effects. Oral administration of MMF significantly inhibited leukocyte influx during the first (4 hours) and second (48 hours) phases of inflammation in a mouse model of pleurisy caused by carrageenan (P < .01). As expected, MMF suppressed protein levels of TNF-α, IL-1β, VEGF-α, and IL-17A (P < .01). This inhibitory effect was due to down-regulation of mRNA expression for these proinflammatory cytokines (P < .01). These results provide evidence of MMF-mediated inhibition of proinflammatory cytokines, and these anti-inflammatory effects are assumed to result mainly from the inhibition of the synthesis and release of TNF-α, IL-1β, VEGF-α, and IL-17A from activated leukocytes. These findings suggest that MMF might be an applicable therapeutic in the regulation of the inflammatory response-a response in which the humoral system plays a pivotal role.

Abstract
Lupus nephritis is a complication of systemic lupus erythematosus, which has significant morbidity and mortality. The accepted standard of treatment for severe lupus nephritis is cyclophosphamide for induction of remission. This has significant adverse effects including severe infection and amenorrhea. In addition, although cyclophosphamide induces remission, long-term mortality does not seem to be altered. Mycophenolate mofetil (MMF) is an immunosuppressive agent originally used in solid organ transplantation, which has been compared with cyclophosphamide in trials for lupus nephritis. Randomized trials with MMF have been relatively small, although pooled data seem to suggest that it is at least as effective as cyclophosphamide in inducing remission. In addition, MMF has also been associated with a reduced risk of infection and amenorrhea, although this finding is not universal. MMF appears to be associated with more diarrhea compared with cyclophosphamide. MMF is likely to be a useful treatment for lupus nephritis, although available trial data are limited due to the small size of previous studies. A large trial (the Aspreva Lupus Management Study) is currently underway to attempt to establish the place of MMF in treatment of lupus nephritis.
