Abstract
Renal involvement in systemic lupus erythematosus (SLE) represents one of the most frequent organ manifestations, often leading to end-stage kidney disease (ESKD). Several therapies have been tested in patients with lupus nephritis (LN) to prevent further organ damage. The effectiveness of immunosuppressive therapy as a treatment for LN is abundant, supported by multiple clinical trials that have shown its efficacy in preventing the development of chronic kidney disease (CKD). In addition to immunosuppressive therapy, several traditional and recent therapies aimed at nephroprotection in patients with proteinuric chronic kidney disease are gaining importance in the setting of LN. Thus, immunosuppressive therapy should be accompanied by nephro- and cardioprotective measures to control cardiovascular risk factors and proteinuria to ensure a better renal prognosis. Despite this, the literature on these specific measures is relatively scarce, with recommendations focused on the blockade of the renin-angiotensin-aldosterone system (RAAS). This review explores the pharmacological options available for cardiovascular and renal protection outside the usual treatment schemes.

Kidney Int 2022; 102:395-404. [PMID: 35618096 PMCID: PMC9329244 DOI: 10.1016/j.kint.2022.04.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 03/07/2022] [Accepted: 04/08/2022] [Indexed: 02/06/2023]
Abstract
There is little data to inform use of renin angiotensin aldosterone system (RAAS) inhibitors in pediatric patients with systemic lupus erythematosus (SLE). Here, we sought to characterize RAAS inhibitor use in pediatric SLE, and determine whether early RAAS inhibitor initiation among children with incident lupus nephritis is associated with decreased duration of chronic glucocorticoid exposure. A retrospective cohort study was performed of children (ages 5-18) with SLE and/or lupus nephritis in the Truven MarketScanΤΜ Medicaid and Commercial databases (2013-2018) and estimated RAAS inhibitor use. Among incident nephritis cases, we used competing risk hazard models with inverse probability of treatment weighting to estimate the association between RAAS inhibitor initiation less than 180 days after diagnosis and time to glucocorticoid discontinuation with kidney failure as a competing event. Among 592 children with nephritis and 1407 children with non-kidney SLE, 67% and 15% ever received RAAS inhibitors, respectively. Median duration of RAAS inhibitor use among 323 incident users was 14 and 9 months in children with and without nephritis, respectively. Medicaid enrollment was independently associated with greater likelihood of RAAS inhibitor use, irrespective of nephritis. Among 158 incident nephritis cases, early RAAS inhibitor initiation was significantly associated with a faster rate of glucocorticoid discontinuation (adjusted sub-distribution hazard ratio 1.81, 95% confidence interval [1.09 - 3.00]). Thus, early initiation of RAAS inhibitors may have a role in children newly diagnosed with lupus nephritis; not only those with refractory proteinuria after induction therapy. Hence, integrated health systems data could be leveraged to confirm these findings and optimize adjunctive therapies in pediatric lupus.

Abstract
There is a well-known increased risk for cardiovascular disease that contributes to morbidity and mortality in systemic lupus erythematosus (SLE). Major adverse cardiovascular events and subclinical atherosclerosis are both increased in this patient population. While traditional cardiac risk factors do contribute to the increased risk that is seen, lupus disease-related factors, medications, and genetic factors also impact the overall risk. SLE-specific inflammation, including oxidized lipids, cytokines, and altered immune cell subtypes all are likely to play a role in the pathogenesis of atherosclerotic plaques. Research is ongoing to identify biomarkers that can help clinicians to predict which SLE patients are at the greatest risk for cardiovascular disease (CVD). While SLE-specific treatment regimens for the prevention of cardiovascular events have not been identified, current strategies include minimization of traditional cardiac risk factors and lowering of overall lupus disease activity.

Abstract
Purpose of the Review The main goal of this article is to discuss how the development of state-of-the-art technology has made it possible to address fundamental questions related to how the renin-angiotensin system (RAS) operates within the brain from the neurophysiological and molecular perspective. Recent Findings The existence of the brain RAS remains surprisingly controversial. New sensitive in situ hybridization techniques and novel transgenic animals expressing reporter genes have provided pivotal information of the expression of RAS genes within the brain. We discuss studies using genetically engineered animals combined with targeted viral microinjections to study molecular mechanisms implicated in the regulation of the brain RAS. We also discuss novel drugs targeting the brain RAS that have shown promising results in clinical studies and trials. Summary Over the last 50 years, several new physiological roles of the brain RAS have been identified. In the coming years, efforts to incorporate cutting-edge technologies such as optogenetics, chemogenetics, and single-cell RNA sequencing will lead to dramatic advances in our full understanding of how the brain RAS operates at molecular and neurophysiological levels.

Abstract
Understanding the causal role of the immune and inflammatory responses in hypertension has led to questions regarding the links between hypertension and autoimmunity. Immune pathology in primary hypertension mimics several autoimmune mechanisms observed in the pathogenesis of systemic lupus erythematosus, psoriasis, systemic sclerosis, rheumatoid arthritis and periodontitis. More importantly, the prevalence of hypertension in patients with these autoimmune diseases is significantly increased, when compared to control populations. Clinical and epidemiological evidence is reviewed along with possible mechanisms linking hypertension and autoimmunity. Inflammation and oxidative stress are linked in a self-perpetuating cycle that significantly contributes to the vascular dysfunction and renal damage associated with hypertension. T cell, B cell, macrophage and NK cell infiltration into these organs is essential for this pathology. Effector cytokines such as IFN-γ, TNF-α and IL-17 affect Na+/H+ exchangers in the kidney. In blood vessels, they lead to endothelial dysfunction and loss of nitric oxide bioavailability and cause vasoconstriction. Both renal and vascular effects are, in part, mediated through induction of reactive oxygen species-producing enzymes such as superoxide anion generating NADPH oxidases and dysfunction of anti-oxidant systems. These mechanisms have recently become important therapeutic targets of novel therapies focused on scavenging oxidative (isolevuglandin) modification of neo-antigenic peptides. Effects of classical immune targeted therapies focused on immunosuppression and anti-cytokine treatments are also reviewed.

Abstract
Systemic lupus erythematosus (SLE) is a systemic disease of unknown aetiology with variable course and prognosis. Lupus nephritis (LN) is one of the important disease manifestations of SLE with considerable influence on patient outcomes. Immunosuppression therapy has made it possible to control the disease with improved life expectancy and quality of life. In the last few decades, various studies across the globe have clarified the role, dose and duration of immunosuppression currently in use and also provided evidence for new agents such as mycophenolate mofetil, calcineurin inhibitors and rituximab. However, there is still a need to develop new and specific therapy with less adverse effects. In this review, the current evidence of the treatment of LN and its evolution, and new classification criteria for SLE have been discussed. Also, rationale for low-dose intravenous cyclophosphamide as induction agent followed by azathioprine as maintenance agent has been provided with emphasis on individualized and holistic approach.

Abstract
Podocalyxin is an electronegative sialoglycoprotein that prevents the podocyte foot process from collapsing. The aim of this study was to detect an association between the glomerular immunohistochemical (IHC) expression of podocalyxin and the degree of podocyte effacement detected by electron microscopy, and to evaluate the role of podocalyxin IHC expression as a novel marker for disease activity in lupus nephritis (LN). METHODS Thirty-two renal biopsies of active lupus nephritis patients were studied. Clinical assessment by the systemic lupus activity measure (SLAM-R) score and laboratory data were included [serum creatinine, 24-h urinary protein, antinuclear antibodies (ANA), anti-double-strand DNA antibodies (anti-dsDNA), C3 and C4]. Light (L/M) and electron microscopic (E/M) examination was conducted. Podocyte loss was evaluated by immunohistochemistry with monoclonal anti-podocalyxin antibodies by means of a semiquantitative score that was graded from 0 to 4+ according to the percentage of glomerular involvement. RESULTS 22 cases (68.8%) with LN class IV, 6 (18.8%) with class III and 4 (12.5%) with class V. The mean age was (25.41±10.13) years. There was a significant negative correlation between IHC podocalyxin score and LN class, and NIH activity parameters such as leukocyte infiltration, endocapillary proliferation, fibrinoid necrosis and cellular crescent and disease activity index but not chronicity index. There was a highly significant negative correlation between IHC podocalyxin and podocyte effacement by E/M (rs=-0.903, P=0.000), and E/M immune deposits (r=-0.53, P=0.001), and a significant association with degree of proteinuria, ANA and SLAM score (P<0.05). CONCLUSIONS Podocyte loss indicated by podocalyxin immunohistochemical expression reflects the degree of activity and severity of LN and the degree of podocyte effacement by E/M.

Abstract
Objective Several studies have reported that tacrolimus (TAC) significantly reduced proteinuria in lupus nephritis (LN) patients and mouse models. However, the mechanism for this effect remains undetermined. This study explored the mechanism of how TAC protects podocytes from injury to identify new targets for protecting renal function. Methods MRL/lpr mice were given TAC at a dosage of 0.1 mg/kg per day by intragastric administration for 8 weeks. Urine and blood samples were collected. Kidney sections (2μm) were stained with hematoxylin-eosin (HE), periodic acid-Schiff base (PAS) and Masson's trichrome stain. Mouse podocyte cells (MPC5) were treated with TAC and/or TGF-β1 for 48h. The mRNA levels and protein expression of synaptopodin and Wilms’ tumor 1 (WT1) were determined by real-time PCR, Western blotting and/or immunofluorescence, respectively. Flow cytometry was used to detect cell apoptosis with annexin V. Podocyte foot processes were observed under transmission electron microscopy. IgG and C3 deposition were assessed with immunofluorescence assays and confocal microscopy. Results Synaptopodin expression significantly decreased in MRL/lpr disease control mice, accompanied by increases in 24-h proteinuria, blood urea nitrogen, and serum creatinine. TAC, however, reduced proteinuria, improved renal function, attenuated renal pathology, restored synaptopodin expression and preserved podocyte numbers. In MPC5 cells, TGF-β1 enhanced F-actin damage in podocytes and TAC stabilized it. TAC also decreased TGF-β1-induced podocyte apoptosis in vitro and inhibited foot process fusion in MRL/lpr mice. In addition, our results also showed TAC inhibited glomerular deposition of IgG and C3. Conclusion This study demonstrated that TAC reduced proteinuria and preserved renal function in LN through protecting podocytes from injury partly by stabilizing podocyte actin cytoskeleton and inhibiting podocyte apoptosis.

Abstract
The prevalence of atherosclerosis (ATH) is higher in patients with systemic lupus erythematosus (SLE) and occurs at an earlier age. The lupus-related factors that account for this increased risk are likely numerous and related to the factors described in this article. Identifying of at-risk subjects and increasing the understanding of pathogenesis of ATH in SLE is critical for improving the quality of care and improving mortality in this vulnerable population.

Abstract
Patients with systemic lupus erythematosus (SLE) have a higher prevalence of clinical and subclinical atherosclerosis compared with age- and sex-matched controls. Atherosclerosis progression is also accelerated in SLE, and coronary heart disease (CHD) is a major cause of morbidity and mortality. Traditional cardiovascular (CV) risk factors, including hypertension, diabetes mellitus or dyslipidemia, are more prevalent in SLE patients than in the general population, but they cannot fully account for accelerated atherosclerosis in SLE. In fact, a number of nontraditional risk factors have been identified, including disease activity, damage and various treatments. Preventive strategies for CHD are mandatory in SLE patients and should include giving up smoking; performing regular physical activity; managing metabolic abnormalities such as dyslipidemia, insulin resistance, and diabetes; treating persistent disease activity; and minimizing chronic exposure to corticosteroids. Low-dose aspirin, angiotensin-converting enzyme (ACE) inhibitors, vitamin D supplementation, antimalarials and, when indicated, some immunosuppressants such as mycophenolate mofetil should also be considered.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease of diverse manifestations, with onset usually in young women in the third to fourth decade of life. The chronic nature of this relapsing remitting disease leads to organ damage accrual over time. Mortality and morbidity are increased in patients with SLE compared with the general population. Therapeutic advances over the last few decades have led to significant improvements in patient outcomes. Five-year survival has improved to over 90% from a low of 50% in the 1950s. However, multiple aspects of the management of SLE patients are still far from optimal. Early diagnosis remains a challenge; diagnostic delays leading to delay in definitive treatment are common. Monitoring treatment remains problematic due to the paucity of sensitive biomarkers. Current treatment regimens rely heavily on corticosteroids, even though corticosteroids are well known to cause organ damage. Treatment of refractory disease manifestations such as nephritis, recalcitrant cutaneous lesions and neurological involvement require new approaches with greater efficacy. Cognitive dysfunction is common in SLE patients, but early recognition and adequate treatment are yet to be established. Premature accelerated atherosclerosis remains a leading cause of morbidity and mortality. Fatigue is one of the most disabling symptoms, and contributes to the poor quality of life in patients with SLE. Ongoing research in SLE faces many challenges, including enrollment of homogeneous patient populations, use of reliable outcome measures and a standard control arm. The current review will highlight some of the outstanding unmet challenges in the management of this complex disease.

Abstract
Lupus nephritis is a common complication of systemic lupus erythematosus (SLE) which is associated with significant morbidity and mortality. The concept of two phases of therapy for lupus nephritis, such as an induction phase and a maintenance phase, is widely accepted. Since the renal involvement in SLE is heterogeneous, the treatment of lupus nephritis is governed by its pathological type and ranges from nonspecific measures, such as maintenance of adequate blood pressure control and blockade of the renin-angiotensin-aldosterone system, to the use of immunosuppressive agents. Cyclophosphamide (CYC) in combination with prednisone has been the standard method of treatment of the proliferative forms of lupus nephritis. However, the high rates of progression to end-stage renal disease coupled with the adverse effects of CYC and prednisone have led to an intensive search for more effective and less toxic therapies for lupus nephritis. We review the options available for the treatment of proliferative and membranous lupus nephritis and summarize the results of recently published clinical trials that add new perspectives to the management of kidney disease in SLE.

Abstract
Studies investigating the association between angiotensin-converting enzyme (ACE) insertion/deletion polymorphisms and the risk of acute respiratory distress syndrome (ARDS) report conflicting results. The objective of the present study was to summarize quantitatively the evidence for such a relationship. Two investigators independently searched the MEDLINE (January 1966 - October 2009) and EMBASE (January 1980 - October 2009) databases. This meta-analysis included six case-control studies, which included 514 ARDS cases and 2619 controls. The combined results based on all studies showed that patients with ARDS had a significantly higher frequency of the ACE deletion/deletion (DD) genotype (odds ratio [OR] 1.56; 95% confidence interval [CI] 1.22, 2.00) than controls. When stratifying for race, no significant differences in genotype distribution were found except that Caucasian patients with ARDS had a significantly higher frequency of the DD genotype (OR 1.65; 95% CI 1.27, 2.13) than controls. This meta-analysis suggests that ACE insertion/deletion polymorphisms may be associated with ARDS among Caucasians.

Abstract
Cardiovascular disease (CVD) is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Patients with SLE have an excess risk compared with the general population; this is particularly pronounced in younger women with SLE who have an excess risk of over 50-fold compared with population controls. There is a higher prevalence of subclinical atherosclerosis in patients with SLE compared with controls, as demonstrated by a variety of imaging modalities discussed in this review. The causality of the excess risk of CVD and subclinical atherosclerosis is multifactorial in patients with SLE. While traditional risk factors play a role, after controlling for the traditional Framingham risk factors, the excess risk is still 7.5-fold greater than the general population. This review will also cover novel cardiovascular risk factors and some SLE-specific variables that contribute to CVD risk. This review discusses the risk factor modification and the evidence available for treatment of these risk factors in SLE. There have not yet been any published randomized, controlled trials in patients with SLE with respect to CVD risk factor modifications. Thus, the treatment and management recommendations are based largely on published guidelines for other populations at high risk for CVD.
