II Brazilian Society of Rheumatology consensus for lupus nephritis diagnosis and treatment. Adv Rheumatol 2024; 64:48. [PMID: 38890752 DOI: 10.1186/s42358-024-00386-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Accepted: 05/25/2024] [Indexed: 06/20/2024] Open
Abstract
OBJECTIVE To develop the second evidence-based Brazilian Society of Rheumatology consensus for diagnosis and treatment of lupus nephritis (LN). METHODS Two methodologists and 20 rheumatologists from Lupus Comittee of Brazilian Society of Rheumatology participate in the development of this guideline. Fourteen PICO questions were defined and a systematic review was performed. Eligible randomized controlled trials were analyzed regarding complete renal remission, partial renal remission, serum creatinine, proteinuria, serum creatinine doubling, progression to end-stage renal disease, renal relapse, and severe adverse events (infections and mortality). The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to develop these recommendations. Recommendations required ≥82% of agreement among the voting members and were classified as strongly in favor, weakly in favor, conditional, weakly against or strongly against a particular intervention. Other aspects of LN management (diagnosis, general principles of treatment, treatment of comorbidities and refractory cases) were evaluated through literature review and expert opinion. RESULTS All SLE patients should undergo creatinine and urinalysis tests to assess renal involvement. Kidney biopsy is considered the gold standard for diagnosing LN but, if it is not available or there is a contraindication to the procedure, therapeutic decisions should be based on clinical and laboratory parameters. Fourteen recommendations were developed. Target Renal response (TRR) was defined as improvement or maintenance of renal function (±10% at baseline of treatment) combined with a decrease in 24-h proteinuria or 24-h UPCR of 25% at 3 months, a decrease of 50% at 6 months, and proteinuria < 0.8 g/24 h at 12 months. Hydroxychloroquine should be prescribed to all SLE patients, except in cases of contraindication. Glucocorticoids should be used at the lowest dose and for the minimal necessary period. In class III or IV (±V), mycophenolate (MMF), cyclophosphamide, MMF plus tacrolimus (TAC), MMF plus belimumab or TAC can be used as induction therapy. For maintenance therapy, MMF or azathioprine (AZA) are the first choice and TAC or cyclosporin or leflunomide can be used in patients who cannot use MMF or AZA. Rituximab can be prescribed in cases of refractory disease. In cases of failure in achieving TRR, it is important to assess adherence, immunosuppressant dosage, adjuvant therapy, comorbidities, and consider biopsy/rebiopsy. CONCLUSION This consensus provides evidence-based data to guide LN diagnosis and treatment, supporting the development of public and supplementary health policies in Brazil.

Belimumab and antimalarials combined against renal flares in patients treated for extra-renal systemic lupus erythematosus: results from 4 phase III clinical trials. Rheumatology (Oxford) 2024; 63:338-348. [PMID: 37228028 PMCID: PMC10836979 DOI: 10.1093/rheumatology/kead253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 04/24/2023] [Accepted: 05/09/2023] [Indexed: 05/27/2023] Open
Abstract
OBJECTIVES To determine the effect of antimalarial agents (AMA) and different doses and pharmaceutical forms of belimumab on preventing renal flares in patients with SLE treated for extra-renal disease. METHODS We pooled data from the BLISS-52, BLISS-76, BLISS-SC and BLISS-Northeast Asia trials of belimumab (n = 3225), that included patients with active SLE yet no severe ongoing nephritis. Participants were allocated to receive intravenous belimumab 1 mg/kg, intravenous belimumab 10 mg/kg, subcutaneous belimumab 200 mg, or placebo in addition to standard therapy. We estimated hazards of renal flare development throughout the study follow-up (52-76 weeks) using Cox regression analysis. RESULTS In total, 192 patients developed a renal flare after a median of 197 days. Compared with placebo, the risk of renal flares was lower among patients receiving intravenous belimumab 10 mg/kg (HR: 0.62; 95% CI: 0.41, 0.92; P = 0.018) and intravenous belimumab 1 mg/kg (HR: 0.42; 95% CI: 0.22, 0.79; P = 0.007), while no significant association was found for subcutaneous belimumab 200 mg. AMA use yielded a lower hazard of renal flares (HR: 0.66; 95% CI: 0.55, 0.78; P < 0.001). The protection conferred was enhanced when belimumab and AMA were co-administered; the lowest flare rate was observed for the combination intravenous belimumab 1 mg/kg and AMA (18.5 cases per 1000 person-years). CONCLUSIONS The protection conferred from belimumab against renal flare development in patients treated for extra-renal SLE appears enhanced when belimumab was administered along with AMA. The prominent effect of low-dose belimumab warrants investigation of the efficacy of intermediate belimumab doses.

Li X, Tan Y, Yu F, Zhao M. Successful glucocorticoid withdrawal in Chinese lupus nephritis patients: A single centre experience. Int Immunopharmacol 2023; 125:111156. [PMID: 37944216 DOI: 10.1016/j.intimp.2023.111156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 10/29/2023] [Accepted: 10/30/2023] [Indexed: 11/12/2023]
Abstract
OBJECTIVE To evaluate the proportion of patients successfully withdrawn from glucocorticoids (GC) in a longitudinal cohort of patients with lupus nephritis over a period of 20 years, clinical and pathological predictors of patients with GC withdrawal and renal outcomes after GC withdrawal were further explored. METHODS Patients with successful GC withdrawal were identified for the cohort, and the following data were collected: demographic characteristics, clinical manifestations, pathological findings at disease onset, flares, and renal outcomes subsequent to GC withdrawal. RESULTS There were 365 patients with lupus nephritis included with a median follow-up of 109.5 (83.5,165.3) months in our cohort. A total of 21 patients (5.8 %) achieved successful GC discontinuation, with a median duration of 7.5 (3,10) years necessary for GC withdrawal. The average duration of GC reduction from 7.5 mg/d to complete withdrawal lasted for approximately 25 months (18,30). Patients in the GC-withdrawal group had a lower prevalence of nephrotic syndrome (NS) at onset (28.5 % vs. 47.3 %, P = 0.035), a higher prevalence of positive anti-double-stranded DNA (anti-dsDNA) antibody (85.7 % vs. 61.6 %, P = 0.028) and more severe endocapillary hypercellularity in the renal histopathology evaluations (3(2.5,3) vs. 3(2,3), P = 0.022). NS at disease onset was an independent risk factor to predict unachievable GC withdrawal (OR 0.296, 95 % CI (0.104,0.842), P = 0.022) by multivariate analysis. With a median follow-up of 34 (20,42) months, none of these patients had flares after GC withdrawal. CONCLUSIONS The discontinuation of GC therapy in LN patients with complete remission and a stable treatment regimen for at least 5 years was feasible without an increased risk of flares, ESKD or death. Low-dose GC withdrawal necessitates a prolonged duration of time and meticulous monitoring.

Allogeneic adipose-derived mesenchymal stromal cell transplantation for refractory lupus nephritis: Results of a phase I clinical trial. Curr Res Transl Med 2021; 70:103324. [PMID: 34979487 DOI: 10.1016/j.retram.2021.103324] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Revised: 10/13/2021] [Accepted: 12/06/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND Mesenchymal stromal/stem cells (MSCs) are known for their immunomodulatory properties. This study was performed to analyse the effects of MSC transplantation on treatment-resistant lupus nephritis (LN). METHODS In this phase I trial, nine biopsy-proven LN patients refractory to standard treatments underwent systemic infusion of 2 × 106 allogeneic adipose-derived (AD) MSCs/kg and were followed for 12 months post-intervention. RESULTS The treatment protocol resulted in no major adverse events. Urine protein levels significantly decreased during the first month post-intervention (baseline vs. month 1 (median): 1800 vs. 1020, P = 0.008), followed by a gradual increase but remained significantly lower than baseline only up to the 3rd month. During the first 3 months post-intervention, complete renal response (proteinuria < 0.5 g/24 h) and partial response (proteinuria > 0.5 g/24 h, but > 50% decrease in proteinuria) were observed in 33.3% and 44.4% of the patients, respectively, though these rates declined thereafter. Median score of Systemic Lupus Erythematosus Disease Activity Index decreased significantly from 16 at the baseline to 6 at sixth months post-treatment (P = 0.007), though it slightly increased at the 12th month follow-up. CONCLUSIONS Allogenic AD-MSC transplantation was associated with favourable safety and efficient to reduce urine protein excretion and disease activity; however, the maximum effect (greatest improvement in outcomes) was observed at 1 month based on the proteinuria, and 6 months post-intervention based on disease activity scores. A single dose of AD-MSCs may not be adequate to maintain long-term remission of refractory LN, and so, additional doses may be required.

Treatment of Lupus Nephritis from Iranian Traditional Medicine and Modern Medicine Points of View: A Comparative Study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6645319. [PMID: 34795786 PMCID: PMC8595000 DOI: 10.1155/2021/6645319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 08/14/2021] [Accepted: 09/24/2021] [Indexed: 12/02/2022]
Abstract
Objective Nephritis or kidney inflammation is characterized as one of the most common renal disorders leading to serious damage to the kidneys. Nephritis, especially lupus nephritis (LN), has remained as the main cause of chronic renal failure which needs serious therapeutic approaches such as dialysis and kidney transplant. Heredity, infection, high blood pressure, inflammatory diseases such as lupus erythematosus and inflammatory bowel disease, and drug-related side effects are known as the main causes of the disease. According to Iranian traditional medicine (ITM), infectious diseases and fever are the main reasons of nephritis, which is called “Varam-e-Kolye” (VK). Results There are various plant-based remedies recommended by ITM for the treatment of nephritis, as discussed herein, comparing with those available in the modern medicine. There is no definite cure for the treatment of nephritis, and immunosuppressive drugs such as corticosteroids and nonsteroidal anti-inflammatory drugs, antibiotics, diuretics, analgesics, and finally dialysis and kidney transplantation are usually used. Based on the efficacy of medicinal plants, jujube (Ziziphus jujuba), almond (Prunus amygdalus), pumpkin seeds (Cucurbita pepo), purslane (Portulaca oleracea), and fig (Ficus carica) were found to be effective for the treatment of kidney inflammation in ITM. Conclusion Considering the fact that there is no efficient strategy for the treatment of nephritis, use of herbal medicine, particularly based on the fruits or nuts that have been safely used for several years can be considered as a versatile supplement along with other therapeutic methods.

Abstract
BACKGROUND Pregnancy in women with systemic lupus erythematosus (SLE) and nephritis (LN) is at risk of foetal and maternal complications. OBJECTIVE To evaluate the effect of LN on pregnancy with respect to foetal and maternal outcome. METHODS We retrospectively studied all pregnant SLE patients with and without diagnosis of LN, who attended the Materno Neonatal Hospital in Cordoba city, Argentina, from January 2015 to April 2017. Demographic, clinical, and laboratory data were collected. The presence of antiphospholipid syndrome (APS) and antiphospholipid antibodies (AAF), and maternal and foetal outcome were evaluated. RESULTS 121 pregnancies in 79 patients were included. Pregnancies were divided into those with LN (69) and those without LN (52). The presence of APS and AAF was more frequent in the LN group as well as higher basal SLEDAI. The LN group received more immunosuppressive therapy and increased steroid dose treatment. Of the patients, 47.5% had Class IV LN. Lupus flares occurred more frequently in the LN group 25.8% vs 10.9% in the group without LN (P = .041), mainly renal flares in the LN group. No patients developed end-stage renal failure. Preeclampsia was more frequent in the LN group, 18.8% vs 6.3% in the group without LN (P = .047). There was only one maternal death. A caesarean section was required in 68.5% of the LN group vs 31.5 in the group without LN, and urgent caesarean section was also performed in the LN group. There were no differences in foetal outcomes in either group: live birth, gestational age, weight birth, perinatal death, foetal distress. CONCLUSIONS Patients with LN experienced more maternal complications such as lupus flares and preeclampsia. However, LN does not lead to a worse pregnancy and foetal outcome. Patients should be strictly monitored before and after conception.

Abstract
Background Screening abnormal pathways and complement components in the kidneys of patients with lupus nephritis (LN) and NZB/W mice may help to identify complement-related therapeutic targets for LN. Methods KEGG and GO enrichment assays were used to analyze kidney microarray data of LN patients and NZB/W mice. Immunohistochemistry and immunofluorescence assays were used to measure renal expression of complement-related proteins and TGFβ1. Cytokines were measured using RT-qPCR and ELISA. Results We screened the renal pathogenic pathways present in LN patients and NZB/W mice and selected the complement activation pathway for further study. The results indicated greater renal expression of C1qa, C1qb, C3, C3aR1, and C5aR1 at the mRNA and protein levels. C3 appeared to be a key factor in LN and the renal signaling downstream of C1 was inhibited. There were significant correlations between the expression of TGFβ1 and C3. Analysis of primary cell cultures indicated that TGFβ1 promoted the expression of C3 and that a TGFβ1 antagonist decreased the levels of C3 and C3aR. TGFβ1 inhibition significantly inhibited the deposition of complement-related factors in the kidneys of NZB/W mice. Conclusions At the onset of LN, there are significant increases in the renal levels of C3 and other complement pathway-related factors in patients with LN and NZB/W mice. C3 may lead to albuminuria and participate in the pathogenesis of LN. TGFβ1 promotes C3 synthesis, and TGFβ1 inhibition may block the progression of LN by inhibiting the synthesis of C3 and other complement components.

Abstract
Objectives To analyse the current evidence for the management of lupus nephritis (LN) informing the 2019 update of the EULAR/European Renal Association-European Dialysis and Transplant Association recommendations. Methods According to the EULAR standardised operating procedures, a PubMed systematic literature review was performed, from January 1, 2012 to December 31, 2018. Since this was an update of the 2012 recommendations, the final level of evidence (LoE) and grading of recommendations considered the total body of evidence, including literature prior to 2012. Results We identified 387 relevant articles. High-quality randomised evidence supports the use of immunosuppressive treatment for class III and class IV LN (LoE 1a), and moderate-level evidence supports the use of immunosuppressive treatment for pure class V LN with nephrotic-range proteinuria (LoE 2b). Treatment should aim for at least 25% reduction in proteinuria at 3 months, 50% at 6 months and complete renal response (<500–700 mg/day) at 12 months (LoE 2a-2b). High-quality evidence supports the use of mycophenolate mofetil/mycophenolic acid (MMF/MPA) or low-dose intravenous cyclophosphamide (CY) as initial treatment of active class III/IV LN (LoE 1a). Combination of tacrolimus with MMF/MPA and high-dose CY are alternatives in specific circumstances (LoE 1a). There is low-quality level evidence to guide optimal duration of immunosuppression in LN (LoE 3). In end-stage kidney disease, all methods of kidney replacement treatment can be used, with transplantation having the most favourable outcomes (LoE 2b). Conclusions There is high-quality evidence to guide the initial and subsequent phases of class III/IV LN treatment, but low-to-moderate quality evidence to guide treatment of class V LN, monitoring and optimal duration of immunosuppression.

Abstract
BACKGROUND Lupus nephritis (LN) is one of the main risk factors contributing to morbidity and mortality of systemic lupus erythematosus (SLE). This study aimed to investigate the potential role of miR-485-5p in human LN. METHODS Quantitative real-time polymerase chain reaction was used for the measurement of miR-485-5p levels. The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in serum were determined by enzyme-linked immunosorbent assay. The diagnostic role of miR-485-5p in LN was evaluated by the receiver operating characteristic (ROC) curve. The impact of miR-485-5p on end-stage renal disease (ESRD) was compared by Kaplan-Meier analysis and Cox regression analysis. The target gene was determined by a dual-luciferase reporter assay system. RESULTS MiR-485-5p was highly expressed in SLE and LN patients compared with the healthy controls, and LN patients had the highest level of miR-485-5p. The expression level of miR-485-5p in active LN patients was significantly increased compared with that in nonactive cases. MiR-485-5p expression showed a positive correlation with the levels of estimated glomerular filtration rate, serum creatinine, proteinuria, SLE disease activity index score, and inflammatory cytokines. The ROC analysis results indicated that serum miR-485-5p was a promising biomarker for the early diagnosis of LN, and it can distinguish active LN patients from nonactive ones. Phosphatase and tensin homolog was a direct target of miR-485-5p, and negatively associated with serum miR-485-5p levels. More ESRD events were observed in cases with high miR-485-5p expression, miR-485-5p was an independent factor for the risk of ESRD in LN patients. CONCLUSION Serum miR-485-5p might be a novel promising diagnostic marker for LN and has potential predictive value for ESRD risk in LN patients.

Abstract
BACKGROUND Pregnancy in women with systemic lupus erythematosus (SLE) and nephritis (LN) is at risk of foetal and maternal complications. OBJECTIVE To evaluate the effect of LN on pregnancy with respect to foetal and maternal outcome. METHODS We retrospectively studied all pregnant SLE patients with and without diagnosis of LN, who attended the Materno Neonatal Hospital in Cordoba city, Argentina, from January 2015 to April 2017. Demographic, clinical, and laboratory data were collected. The presence of antiphospholipid syndrome (APS) and antiphospholipid antibodies (AAF), and maternal and foetal outcome were evaluated. RESULTS 121 pregnancies in 79 patients were included. Pregnancies were divided into those with LN (69) and those without LN (52). The presence of APS and AAF was more frequent in the LN group as well as higher basal SLEDAI. The LN group received more immunosuppressive therapy and increased steroid dose treatment. Of the patients, 47.5% had ClassIV LN. Lupus flares occurred more frequently in the LN group 25.8% vs 10.9% in the group without LN (P=.041), mainly renal flares in the LN group. No patients developed end-stage renal failure. Preeclampsia was more frequent in the LN group, 18.8% vs 6.3% in the group without LN (P=.047). There was only one maternal death. A caesarean section was required in 68.5% of the LN group vs 31.5 in the group without LN, and urgent caesarean section was also performed in the LN group. There were no differences in foetal outcomes in either group: live birth, gestational age, weight birth, perinatal death, foetal distress. CONCLUSIONS Patients with LN experienced more maternal complications such as lupus flares and preeclampsia. However, LN does not lead to a worse pregnancy and foetal outcome. Patients should be strictly monitored before and after conception.

Abstract
BACKGROUND The information concerning non-invasive, easily obtainable, and accurate biomarkers for diagnosis of lupus nephritis (LN) is extremely limited. The aim of this study was to evaluate the diagnostic performance of cystatin C (CysC) and complement component 1q (C1q) for LN. METHODS A case-control study that included 905 patients with systemic lupus erythematosus (SLE) without LN (group SLE), 334 patients with active lupus nephritis (group LNA), 255 patients with inactive lupus nephritis (group LNI), and 497 healthy individuals (group HC) was performed in Mianyang Central Hospital from March 2017 to December 2018. The serum levels of CysC, C1q, urea (Urea), and creatinine (Creat) were measured, and 2 estimated glomerular filtration rates (eGFRCysC and eGFRCreat) were calculated by equations which were based on serum CysC established by our group and the modification of diet in renal disease (MDRD), respectively. ANOVA analysis or Kruskal-Wallis test was used for comparing the differences among the groups, and receiver operating characteristic (ROC) curve was applied to identify the diagnostic efficiencies of individual or combined multiple indicators. RESULTS Significantly elevated CysC and decreased C1q were observed in the LNA and LNI groups, which was in contrast to their levels in the SLE and HC groups. CysC (AUC = 0.906) or eGFRCysC (AUC = 0.907) assessed the highest diagnostic performance on LNA when detected individually, followed by C1q (AUC = 0.753). Joint utilization of C1q and CysC achieved very good performance (AUC = 0.933) which approximated to the best one observed in the combinations of C1q, Urea, CysC, eGFRCreat, and Creat (AUC = 0.975). CONCLUSION The separately detected CysC (eGFRCysC) and C1q were superior to the conventional biomarkers Urea, Creat, and eGFRCreat in the diagnosis of LNA. Moreover, although the combined detection of Urea, Creat, C1q, CysC, and eGFRCreat had the greatest diagnostic performance, the joint utilization of CysC and C1q could be prioritized for rapid discrimination of LNA if the economic burden is taken into consideration.

Abstract
Our objective was to update the EULAR recommendations for the management of systemic lupus erythematosus (SLE), based on emerging new evidence. We performed a systematic literature review (01/2007–12/2017), followed by modified Delphi method, to form questions, elicit expert opinions and reach consensus. Treatment in SLE aims at remission or low disease activity and prevention of flares. Hydroxychloroquine is recommended in all patients with lupus, at a dose not exceeding 5 mg/kg real body weight. During chronic maintenance treatment, glucocorticoids (GC) should be minimised to less than 7.5 mg/day (prednisone equivalent) and, when possible, withdrawn. Appropriate initiation of immunomodulatory agents (methotrexate, azathioprine, mycophenolate) can expedite the tapering/discontinuation of GC. In persistently active or flaring extrarenal disease, add-on belimumab should be considered; rituximab (RTX) may be considered in organ-threatening, refractory disease. Updated specific recommendations are also provided for cutaneous, neuropsychiatric, haematological and renal disease. Patients with SLE should be assessed for their antiphospholipid antibody status, infectious and cardiovascular diseases risk profile and preventative strategies be tailored accordingly. The updated recommendations provide physicians and patients with updated consensus guidance on the management of SLE, combining evidence-base and expert-opinion.

Abstract
Autoimmune rheumatic diseases are characterised by an abnormal immune system response, complement activation, cytokines dysregulation and inflammation. In last years, despite many progresses in managing these patients, it has been shown that clinical remission is reached in less than 50% of patients and a personalised and tailored therapeutic approach is still lacking resulting in a significant gap between guidelines and real-world practice. In this context, the need for biomarkers facilitating early diagnosis and profiling those individuals at the highest risk for a poor outcome has become of crucial interest. A biomarker generally refers to a measured characteristic which may be used as an indicator of some biological state or condition. Three different types of medical biomarkers has been suggested: i. mechanistic markers; ii. clinical disease markers; iii. therapeutic markers. A combination of biomarkers from these different groups could be used for an ideal more accurate diagnosis and treatment. However, although a growing body of evidence is focused on improving biomarkers, a significant amount of this information is not integrated on standard clinical care. The overarching aim of this work was to clarify the meaning of specific biomarkers during autoimmune diseases; their possible role in confirming diagnosis, predicting outcome and suggesting specific treatments.

Abstract
Lupus nephritis (LN) is one of the most severe complications of systemic lupus erythematosus (SLE) caused by uncontrolled activation of the complement system. Mesenchymal stem cells (MSCs) exhibit clinical efficacy for severe LN in our previous studies, but the underlying mechanisms of MSCs regulating complement activation remain largely unknown. Here we show that significantly elevated C5a and C5b-9 were found in patients with LN, which were notably correlated with proteinuria and different renal pathological indexes of LN. MSCs suppressed systemic and intrarenal activation of C5, increased the plasma levels of factor H (FH), and ameliorated renal disease in lupus mice. Importantly, MSCs transplantation up-regulated the decreased FH in patients with LN. Mechanistically, interferon-α enhanced the secretion of FH by MSCs. These data demonstrate that MSCs inhibit the activation of pathogenic C5 via up-regulation of FH, which improves our understanding of the immunomodulatory mechanisms of MSCs in the treatment of lupus nephritis.

Abstract
OBJECTIVE To evaluate the prevalence, duration and effect on damage accrual of the 'Lupus Low Disease Activity State' (LLDAS) in a monocentric cohort of patients with systemic lupus erythematosus (SLE). METHODS We studied 293 Caucasian patients with SLE during a 7-year follow-up period. Disease activity was assessed by SLE Disease Activity Index 2000 (SLEDAI-2K) and SELENA-SLEDAI physician global assessment (PGA), and damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). We considered the following definition of LLDAS: SLEDAI-2K ≤4 without major organ activity, no new disease activity, PGA (0-3)≤1, prednisone ≤7.5 mg/day and well-tolerated immunosuppressant dosages. The effect of LLDAS on SDI was evaluated by multivariate regression analysis. We also evaluated remission defined as clinical SLEDAI-2K=0 and prednisone ≤5 mg/day in patients treated with/without stable immunosuppressants and/or antimalarials. RESULTS LLDAS lasting 1, 2, 3, 4 or ≥5 consecutive years was achieved by 33 (11.3%), 43 (14.7%), 39 (13.3%), 31 (10.6%) and 109 (37.2%) patients, respectively. Patients who spent at least two consecutive years in LLDAS had significantly less damage accrual compared with patients never in LLDAS (p=0.001), and they were significantly less likely to have an increase in SDI (OR 0.160, 95% CI 0.060 to 0.426, p<0.001). On average, 84% of patients in LLDAS also fulfilled the criteria for remission. CONCLUSIONS LLDAS was associated with a decrease in damage progression in Caucasian patients with SLE. The majority of patients in LLDAS were in remission, which can largely contribute to the protective effect of LLDAS on damage accrual.

Abstract
BACKGROUND Lupus nephritis (LN) is a major complication of systemic lupus erythematosus (SLE). This study tested miR-146a and its target gene TRAF6 expression in LN patients and discussed their relationship with LN. MATERIAL AND METHODS One hundred twenty-eight LN patients and 30 healthy controls were enrolled in this study. MiR-146a and TRAF6 expression in peripheral blood mononuclear cells (PBMCs) were detected. Serum cytokines content was determined by ELISA. The diagnostic role of miR-146a and TRAF6 in LN activity was evaluated by ROC curve. The impact of miR-146a and TRAF6 on end-stage renal disease (ESRD) was compared by survival curve. The effect of miR-146a and TRAF6 on LN recurrence was analyzed. RESULTS Compared with healthy controls, miR-146a expression was significantly reduced and TRAF6 was upregulated in LN patients. The expression was related to LN activity. MiR-146a expression was negatively correlated, whereas TRAF6 was positively correlated with serum IL-1β, IL-6, IL-8, and TNF-α activity. The area under the ROC curve (AUC) of miR-146a and TRAF6 on the diagnosis of LN was 0.821 and 0.897, respectively. The AUC of miR-146a and TRAF6 on LN activity differentiation was 0.921 and 0.872, respectively. Downregulation of miR-146a and upregulation of TRAF6 increased the incidence of ESRD progression. Downregulation of miR-146a and upregulation of TRAF6 elevated the possibility of recurrence within one year. CONCLUSIONS MiR-146a declined, while TRAF6 increased in LN patients compared with healthy controls. Their expression can be used to effectively differentiate LN and evaluate activity. MiR-146a reduction and TRAF6 upregulation increased the possibility of ESRD progress and recurrence within one year.

The effect of different durations of remission on damage accrual: results from a prospective monocentric cohort of Caucasian patients. Ann Rheum Dis 2016; 76:562-565. [PMID: 27884821 DOI: 10.1136/annrheumdis-2016-210154] [Citation(s) in RCA: 84] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2016] [Revised: 10/12/2016] [Accepted: 10/21/2016] [Indexed: 11/04/2022]
Abstract
AIM To identify the shortest duration of remission associated with improved outcomes in systemic lupus erythematosus (SLE). METHODS We studied 293 Caucasian patients with SLE during 7-year follow-up. Disease activity was assessed by SLE Disease Activity Index 2000 and damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). We defined three remission levels: complete, clinical off-corticosteroids, clinical on-corticosteroids (prednisone 1-5 mg/day). The effect of different durations of remission (1, 2, 3, 4 and ≥5 consecutive years) on damage was evaluated by multivariate logistic regression analysis. RESULTS Among patients achieving 1-year (27 patients), 2-year (47 patients), 3-year (45 patients), 4-year (26 patients) remission, damage was similar irrespective of the level of remission achieved, whereas, among patients achieving ≥5-year remission (113 patients), damage was higher in those in clinical remission on-corticosteroids (p<0.001).In multivariate analysis, ≥2 consecutive year remission was protective against damage (OR (95% CI)): 2 years 0.228 (0.061 to 0.850); 3 years 0.116 (0.031 to 0.436); 4 years 0.118 (0.027 to 0.519) and ≥5 years 0.044 (0.012 to 0.159). Predictors of damage were cumulative prednisone dose ≥180 mg/month (3.136 (1.276 to 7.707)), antiphospholipid antibody syndrome (5.517 (2.092 to 14.546)), vasculitis (3.107 (1.030 to 9.307)) and number of flare/year (8.769 (1.692 to 45.449)). CONCLUSIONS Two consecutive years is the shortest duration of remission associated with a decrease in damage progression in Caucasian patients with SLE.

THE AMERICAN JOURNAL OF PATHOLOGY 2016; 186:2772-2782.

Abstract
Divergent incommensurable models have been developed to explain the pathogenesis of lupus nephritis. Most contemporary models favor a central role for anti-chromatin antibodies. How they exert their pathogenic effect has, however, endorsed conflicts that at least for now preclude insight into definitive pathogenic pathways. The following paradigms are contemporarily in conflict with each other: i) the impact of anti-double-stranded DNA (dsDNA) antibodies that cross-react with inherent renal antigens, ii) the impact of anti-dsDNA antibodies targeting exposed chromatin in glomeruli, and iii) the impact of relative antibody avidity for dsDNA, chromatin fragments, or cross-reacting antigens. Aside from these three themes, the pathogenic role of T cells in lupus nephritis is not clear. These different models should be tested through a collaboration between scientists belonging to the different paradigms. If it turns out that there are different pathogenic pathways in lupus nephritis, the emerging pathogenic mechanism(s) may be encountered with new individual causal therapy modalities. Today, therapy is still unspecific and far from interfering with the cause(s) of the disorder. This review attempts to describe what we know about processes that may cause lupus nephritis and how such basic processes may be affected if we can specifically interrupt them. Secondary inflammatory mechanisms, cytokine signatures, activation of complement, and other contributors to inflammation will not be discussed herein; rather, the events that trigger these factors will be discussed.
