Metabolic syndrome in systemic lupus erythematosus patients under Mediterranean diet. Med Clin (Barc) 2024; 162:259-264. [PMID: 38040571 DOI: 10.1016/j.medcli.2023.10.009] [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: 07/20/2023] [Revised: 10/10/2023] [Accepted: 10/11/2023] [Indexed: 12/03/2023]
Abstract
BACKGROUND AND AIMS Metabolic syndrome (MetS) is a chronic proinflammatory and prothrombotic condition that exacerbates insulin resistance, oxidative damage, and cardiovascular risk, being more prevalent in patients with systemic lupus erythematosus (SLE), a chronic multisystemic autoimmune disorder. This study aim was to determine the prevalence of MetS and associations with SLE clinical characteristics, cardiovascular risk and dietary pattern in a population of Spanish SLE patients. DESIGN AND METHODS Cross-sectional study of 293 patients was conducted (90.4% females; mean age 46.8 (12.94)). The diagnosis of MetS was established based on the criteria of the National Cholesterol Education Program Adult Treatment Panel III. SLE Disease Activity Index (SLEDAI-2K) and SDI Damage Index were used to assess disease activity and disease-related damage, respectively. Med Diet adherence was assessed through a 14 items questionnaire on food consumption frequency and habits. RESULTS MetS was present in 15% SLE patients. Triglycerides, high-density lipoprotein cholesterol, systolic blood pressure and waist circumference were significantly increased (p<0.001) in the group of MetS patients. Patients with MetS showed significantly increased SDI damage index (1.70 (1.69) vs 0.88 (1.12), p<0.001) and complement C3 level (118.70 (32.67) vs 107.55 (26.82), p=0.011). No significant differences were observed according to Med Diet adherence level. CONCLUSION We observed a lower prevalence of MetS in SLE than that reported in previous studies, which may be a result of the good level of adherence to the MedDiet in our study sample. Additionally, MetS was associated with higher SDI and complement C3 levels but no with medication use.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is an autoimmune disease that typically affects women aged 16-55 years. Cardiovascular disease (CVD) is a well-recognized complication of SLE. This systematic literature review and meta-analysis evaluated the relative risk (RR; compared with non-SLE controls), absolute risk (AR; as incidence proportion, n/N), and incidence rate (IR) of CVD events (including stroke, myocardial infarction [MI], and CVD [composite or undefined]) in adult patients with SLE. The RR of CV risk factors (including hypertension, diabetes, and metabolic syndrome [MetS]) was also examined. METHODS PubMed and Embase were searched on September 10, 2020. Observational studies published between January 2010 and September 2020 that reported RR, AR, and/or IR of CVD events, or RR of CV risk factors, were eligible. Pooled risk estimates were calculated using a random-effects model. RESULTS Forty-six studies (16 cross-sectional, 15 retrospective cohort, 14 prospective cohort, and 1 case-control) were included in meta-analyses. Most studies were considered high quality (Critical Appraisal Skills Programme checklists). Compared with adults without SLE, patients with SLE had statistically significantly higher RRs (95% CIs) of stroke (2.51 [2.03-3.10]; 12 studies), MI (2.92 [2.45-3.48]; 11 studies), CVD (2.24 [1.94-2.59]; 8 studies), and hypertension (2.70 [1.48-4.92]; 7 studies). RRs of diabetes (1.24 [0.78-1.96]; 3 studies) and MetS (1.49 [0.95-2.33]; 7 studies) were elevated but not significant. RRs of stroke and MI were generally higher in younger versus older patients with SLE. In patients with SLE, the pooled estimate of AR (95% CI) was 0.03 (0.02-0.05), 0.01 (0.00-0.02), and 0.06 (0.03-0.10) for stroke (7 studies), MI (6 studies), and CVD (8 studies), respectively. The pooled estimate of IR per 1000 person-years (95% CI) was 4.72 (3.35-6.32), 2.81 (1.61-4.32), and 11.21 (8.48-14.32) for stroke (10 studies), MI (6 studies), and CVD (8 studies), respectively. Although heterogeneity (based on I2 value) was high in most analyses, sensitivity analyses confirmed the robustness of the pooled estimates. CONCLUSIONS This meta-analysis found an increased risk of stroke, MI, CVD, and hypertension in patients with SLE compared with the general population, despite substantial heterogeneity across the included studies.

Abstract
INTRODUCTION Metabolic syndrome is a pathological entity associated with a high risk of cardiovascular disease. Data regarding the frequency of this syndrome, lipid profile, and atherogenic index of plasma in patients with radiographic axial spondyloarthritis are scarce. We aim to determine the prevalence of metabolic syndrome in patients with spondyloarthritis. We also aim to determine discriminative values of atherogenic indexes between patients with and without metabolic syndrome. METHODS We conducted a cross-sectional study including 51 patients meeting the ASAS 2009 criteria for radiographic axial spondyloarthritis. We measured the following parameters: triglyceride (TG), high-density lipoproteins (HDLc), low-density lipoprotein cholesterol (LDLc), and total cholesterol (TC). We calculated TC/HDLc, TG/HDLc, LDLc/HDLc ratios, and atherogenic index of plasma (LogTG/HDLc). RESULTS Metabolic syndrome was noted in 33% of cases. Patients with active disease had a higher body mass index (26.89±5.88 versus 23.63±4.47kg/m2, p=0.03), higher TG (1.41±0.64 versus 0.89±0.5mmol/L, p=0.05) and a lower HDLc level (1±0.28 versus 1.31±0.22mmol/L, p=0.01). However, the LogTG/HDLc and TG/HDLc were higher in patients under TNFα inhibitors. The ability of the TG/HDLc ratio and LogTG/HDLc to distinguish patients with or without metabolic syndrome were good at cut-offs of 1.33 and 0.22, respectively (specificity: 91.2% and sensitivity 70.6% for both ratios). CONCLUSION Our study showed that metabolic syndrome is frequent in patients with axial spondyloarthritis. Atherogenic indexes can be used for predicting metabolic syndrome in these patients.

Abstract
A high prevalence of metabolic syndrome (MetS) has been reported in multiple cohorts of systemic lupus erythematosus (SLE) patients, most likely as one of the consequences of autoimmune pathogenesis. Although MetS has been associated with inflammation, its consequences on the lupus immune system and on disease manifestations are largely unknown. The metabolism of immune cells is altered and overactivated in mouse models as well as in patients with SLE, and several metabolic inhibitors have shown therapeutic benefits. Here we review recent studies reporting these findings, as well as the effect of dietary interventions in clinical and preclinical studies of SLE. We also explore potential causal links between systemic and immunometabolism in the context of lupus, and the knowledge gap that needs to be addressed.

Abstract
Significance: Metformin has been proposed as a treatment for systemic lupus erythematosus (SLE). The primary target of metformin, the electron transport chain complex I in the mitochondria, is associated with redox homeostasis in immune cells, which plays a critical role in the pathogenesis of autoimmune diseases. This review addresses the evidence and knowledge gaps on whether a beneficial effect of metformin in lupus may be due to a restoration of a balanced redox state. Recent Advances: Clinical trials in SLE patients with mild-to-moderate disease activity and preclinical studies in mice have provided encouraging results for metformin. The mechanism by which this therapeutic effect was achieved is largely unknown. Metformin regulates redox homeostasis in a context-specific manner. Multiple cell types contribute to SLE, with evidence of increased mitochondrial oxidative stress in T cells and neutrophils. Critical Issues: The major knowledge gaps are whether the efficacy of metformin is linked to a restored redox homeostasis in the immune system, and if it does, in which cell types it occurs? We also need to know which patients may have a better response to metformin, and whether it corresponds to a specific mechanism? Finally, the identification of biomarkers to predict treatment outcomes would be of great value. Future Directions: Mechanistic studies must address the context-dependent pharmacological effects of metformin. Multiple cell types as well as a complex disease etiology should be considered. These studies must integrate the rapid advances made in understanding how metabolic programs direct the effector functions of immune cells. Antioxid. Redox Signal. 36, 462-479.

Abstract
Background Systemic lupus erythematosus (SLE), often affects women of childbearing age. Family planning consultation is a major aspect of medical care in these patients because of the risk of disease activation and poor pregnancy and fetal outcomes. The aim of the present study was to evaluate contraceptive prevalence and consulting service in women with SLE. Methods In a cross-sectional study, a total of 144 female patients with SLE, ages 15–50, who were presented to rheumatology clinics in Sari, north of Iran, were evaluated. The study was conducted between March 2019 and May 2020. Patients' clinico-demographic profile and fertility information were obtained. Disease activity and damage were assessed by the systemic lupus erythematosus disease activity (SLEDAI) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index (SDI). Results One hundred and forty-four SLE patients of childbearing age participated in this study. From 102 patients with the possibility of pregnancy, 36(35.2%) received contraceptive consultations in last year. Withdrawal was the most prevalent contraceptive method (41.7%), followed by permanent (11.8%), and barrier methods (9%). There were no significant differences in age, disease duration, marriage duration, SDI or SLEDAI scores between the women who received or not received contraceptive counseling (P>0.05). Conclusion Many SLE patients did not receive adequate information about contraception, and it may be associated with many adverse effects on disease activity and pregnancy outcomes. Therefore, contraceptive consultation as an important aspect of patient's management is strongly suggested.

Abstract
OBJECTIVE To assess serum FABP4 and other metabolic-related parameters in Systemic Lupus Erythematosus (SLE) active and non-active episode. METHODS Fifty-four SLE patients in Hasan Sadikin General Hospital, Bandung, Indonesia in 2018-2019 were recruited and serum samples were collected in their active and non-active episode status. Serum was analyzed for FABP4, leptin, glucose, and triglycerides. The clinical characteristics were analyzed from medical records. Disease activity was assessed with the SLEDAI-2K (≥4 defined as an active; <4 as non-active episode). RESULTS Significantly correlation of Systolic Blood Pressure (SBP) (p = 0.001, r = 0.59) and C3 (p = 0.04, r = 0.47) between active and non-active episode. In non-active episode, there was significant correlation of FABP4 with Diastolic Blood Pressure (DBP) (p = 0.04, r = 0.26) and blood glucose (p = 0.01, r = -0.39). In active episode, there was significant correlation FABP4 with SBP (p = 0.04, r = -0.28) and triglyceride (p = 0.002, r = 0.55). CONCLUSION FABP4 correlates with high DBP in the non-active and high triglyceride serum in the active episode.

Abstract
Systemic lupus erythematosus (SLE) is a typical autoimmune disease characterized by chronic inflammation and pathogenic auto-antibodies. Apart from B cells, dysregulation of other immune cells also plays an essential role in the pathogenesis and development of the disease including CD4+T cells, dendritic cells, macrophages and neutrophils. Since metabolic programs control immune cell fate and function, they are critical checkpoints in an effective immune response and are involved in the etiology of autoimmune disease. In addition, mitochondria and oxidative stress are both involved in cellular metabolism and is also essential in immune response. In this review, apart from the disturbed immune system, we will discuss mitochondrial dysfunction, oxidative stress, abnormal metabolism (including glucose, lipid and amino acid metabolism) of immune cells as well as epigenetic control of metabolism reprogramming to elucidate the underlying pathogenic mechanisms of systemic lupus erythematosus. Mitochondria plays a vital role in cellular metabolism and is involved in immune response. There are alterations in glucose, lipid and amino acid metabolism of various immune cells in SLE patients. Epigenetic status is influenced by the presence of metabolic intermediates and certain autoimmunity-related genes are hypomethylated in CD4+T cells, CD19+ B cells as well as CD14+ monocytes of SLE.

Abstract
About half of patients with systemic lupus erythematosus (SLE) are diagnosed with lupus nephritis (LN). Patients with SLE are also at increased risk for diabetes, hypertension and obesity, which together account for >70% of end-stage renal disease in the general population. The frequencies of non-LN related causes of kidney disease, and their contribution to kidney disease development and progression among patients with SLE have been inadequately studied. We hypothesize that a substantial, and increasing proportion of kidney pathology in patients with SLE might not directly relate to LN but instead might be explained by non-immune mediated factors such as diabetes, hypertension, and obesity. The goal of the manuscript is to draw attention to hypertension, diabetes and obesity as potential alternative causes of kidney damage in patients with SLE. Further, we suggest that misclassification of kidney disease etiology in patients with SLE might have important ramifications for clinical trial recruitment, epidemiologic investigation, and clinical care. Future studies aiming to elucidate and distinguish discrete causes of kidney disease - both clinically and histologically - among patients with SLE are desperately needed as improved understanding of disease mechanisms is paramount to advancing therapeutic discovery. Collaboration among rheumatologists, pathologists, nephrologists, and endocrinologists, and the availability of dedicated research funding, will be critical to the success of such efforts.

Abstract
Obesity and nutrients intake deficiencies may contribute to the clinical manifestations and inflammatory processes in systemic lupus erythematosus (SLE). The aim of this study was to assess the relationship between nutritional status and dietary intake with clinical variables in Mexican-mestizo SLE patients. A cross-sectional study was conducted in 130 female SLE patients, classified by the 1997 SLE American College of Rheumatology (ACR) criteria; the clinical activity was evaluated by the Mexican-Systemic Lupus Erythematosus-Disease Activity Index (Mex-SLEDAI); body mass index (BMI) by the World Health Organization (WHO) criteria; the energy calculation and nutritional intake were performed by Nutritionist Pro Diet software. SLE patients with excess weight (BMI > 25 kg/m2) showed a higher score of clinical activity (Mex-SLEDAI = 2; p = 0.003), higher clinical activity prevalence (40.9%; p = 0.039) and a significant association for high clinical activity (odds ratio (OR) = 2.52; 95% confidence interval (CI) = 1.08-5.9; p = 0.033), in comparison with patients without excess weight (BMI < 25 kg/m2). In particular, the excess weight increased the Mex-SLEDAI score (β coefficient = 1.82; R2 = 0.05; p = 0.005). Also, the SLE patients presented a high prevalence (%) of deficient consumption (cut-off point: <67% of dietary adequacy) of vitamin E (100%), iodine (96%), omega 3 (93.44%), biotin (78%), vitamin K (73.33%), iron (67%), vitamin D (63.3%), potassium (59%), folic acid (56.67%), pantothenic acid (43.3%), vitamin A (41.67%) and zinc (32%). In conclusion, in SLE patients the excess weight was associated with increased clinical activity and to the presence of deficiencies in some essential nutrients ingested.

Abstract
Introduction: The metabolic syndrome (MetS) is now recognized as a chronic proinflammatory and prothrombotic state that aggravates insulin resistance, oxidative injury, and cardiovascular risk. MetS is more prevalent in patients with systemic lupus erythematosus (SLE), a prototype of systemic autoimmune disease associated with premature atherosclerosis that cannot be accounted by traditional vascular risk factors alone. Dysregulation of the cytokines and adipokines is a common feature in both SLE and MetS, suggesting a complex relationship among autoimmunity, obesity, inflammation, and atherosclerosis. Areas covered: This review summarizes the prevalence of MetS and its effect on cardiovascular outcome and organ damage in patients with SLE. The pathophysiology of MetS and its relevance to SLE is also briefly discussed. Expert opinion: Imbalance of adipokine production in MetS contributes to inflammation and atherosclerosis. MetS predisposes SLE patients to new cardiovascular events and vascular mortality, as well as the development of chronic kidney disease and diabetes mellitus. However, conflicting results have been reported in the literature regarding the levels of the proinflammatory leptin and anti-inflammatory adiponectin, and their relationship with disease activity in SLE patients. While lifestyle modifications and targeting dyslipidemia, hypertension and diabetes mellitus is essential, there is little information on the efficacy and safety of metformin and hydroxychloroquine in alleviating insulin resistance in SLE or MetS. Further research on adipokines in SLE and the role of anti-obesity medications and probiotics in MetS is necessary.
