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.

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease involving multiple organ systems. The kidney appears to be the most commonly affected organ, especially nephrotic is a serious kidney injury. The clinical, laboratory manifestations and histopathology are very useful for diagnosis, provide the means of predicting prognosis and guiding therapy in nephrotic patients with lupus nephritis. Methods: Descriptive cross-sectional study of nephrotic patients with lupus treated in the Department of Nephrology Trung Vuong Hospital and Cho Ray Hospital between May/2014 and May/2017. Renal histopathological lesions were classified according to International Society of Nephrology/Renal Pathology Society - ISN/RPS ’s 2003. The clinical, laboratory manifestations and histopathological features were described. Results: Of 32 LN with nephritic range proteinuria cases studied, 93.7% were women. The 3 most common clinical manifestations were edema (93.8%), hypertension (96.8%) and pallor (68.9%), musculoskeletal manifestions (46.9%), malar rash (40.6%). There was significant rise in laboratory and immunological manifestions with hematuria (78.1%), Hb < 12g/dL (93.5%), increased Cholesterol (100%), and Triglycerid (87.5%), Creatinine > 1.4 mg/dL (87.5%), increased BUN 71.9%, ANA (+) 93.8%, Anti Ds DNA(+) 96.9%, low C3: 96.9%, low C4: 84.4%. The most various and severe features were noted in class IV with active tubulointerstitial lesions and high activity index. Conclusion: Lupus nephritis with nephrotic range proteinuria has the more severity of histopathological feature and the more severity of the more systemic organ involvements and laboratory disorders were noted.

Objective This study aimed to assess IL-24 levels and their association with clinical manifestations in patients with systemic lupus erythematosus (SLE). Methods There were 75 patients with SLE and 58 healthy controls recruited in this study. Serum levels of IL-24 were measured by enzyme-linked immunosorbent assays, and mRNA levels of IL-24 were tested by quantitative real-time polymerase chain reaction . The area under the curve of the receiver operating characteristic (ROC) curve was used for diagnostic ability of the inflammatory cytokine. Results Serum IL-24 levels were significantly higher in SLE patients than that in healthy controls. SLE patients with nephritis had higher IL-24 levels than those without nephritis. Active SLE patients showed higher expression of IL-24 as compared to less active disease patients. The mRNA levels of IL-24 were much higher in SLE patients. Correlation analysis showed significant correlation between serum IL-24 levels and SLE disease activity index. In addition, ROC analysis may suggest good ability of serum IL-24 in differentiating SLE. Conclusion The inflammatory cytokine correlated with SLE disease activity, and may be involved in this disease pathogenesis.

Objective To describe long-term clinical and serological outcome in all systemic lupus erythematosus (SLE) domains in SLE patients with hand arthralgia (HA) and joint ultrasound (JUS) inflammatory abnormalities, and to compare them with asymptomatic SLE patients with normal JUS. Methods SLE patients with HA who presented JUS inflammatory abnormalities (‘cases’) and SLE patients without HA who did not exhibit JUS abnormalities at baseline (‘controls’) were included. All SLE clinical and serological domain involvement data were collected. End follow-up clinical activity and damage scores (systemic lupus erythematosus disease activity index (SLEDAI), Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR)) were recorded. JUS inflammatory abnormalities were defined based on the Proceedings of the Seventh International Consensus Conference on Outcome Measures in Rheumatology Clinical Trials (OMERACT-7) definitions. Statistical analyses were carried out to compare ‘cases’ and ‘controls’. Results A total of 35 patients were recruited. The ‘cases’, n = 18/35, had a higher incidence of musculoskeletal involvement (arthralgia and/or arthritis) through the follow-up period (38.9% vs 0%, p = 0.008) and received more hydroxychloroquine (61.1% vs 25.0%, p = 0.034) and methotrexate (27.8% vs 0%, p = 0.046) compared to ‘controls’, n = 17/35. Other comparisons did not reveal any statistical differences. Conclusions We found SLE patients with arthralgia who presented JUS inflammatory abnormalities received more hydroxychloroquine and methotrexate, mainly due to persistent musculoskeletal involvement over time. JUS appears to be a useful technique for predicting worse musculoskeletal outcome in SLE patients.

Abstract Background Human herpesviruses (HHVs) are responsible for a significant number of clinical manifestations in systemic lupus erythematous (SLE) patients. The aim of this study was to determine the frequency of active HHV infections in SLE patients and correlating them with disease activity. Methods Serum samples were collected from 71 SLE patients and their DNAs were extracted and analyzed to detect HHV-DNA viruses using the nucleic acid amplification technique. Results Fifteen out of the 71 (21.1%) patients tested positive for the HHV-DNA virus. Of them, 11/15 HHV-DNA-positive patients (73.3%) had SLE activity index (SLEDAI – Systemic Lupus Erythematosus Disease Activity Index) ≥8 (p = 0.0001). Active HCMV infection was the mostly frequently observed infection, occurring in 6/15 patients (40%). The frequencies of other active viral infections were 22% for HSV-1, 16.7% for HHV-7, and 5.5% for HSV-2. Viral coinfection (two or more viruses detected in the same sample) occurred in three patients (16.7%). Active HHV infections in SLE patients are more frequent in those with active SLE (≥8), who is at high risk of HHV reactivation and HCMV disease. Conclusion Viral surveillance is important to identify active HHV infections that can cause clinical symptoms and other complication in SLE patients.

Objective.Disease course in systemic lupus erythematosus (SLE) is primarily relapsing-remitting. Long quiescent and chronically active patterns are less frequent. We recently described an atypical “monophasic” course in a small number of patients. The aim of the present study was to assess the prevalence and characteristics of such patients in a defined SLE cohort.Methods.The inception patients of the University of Toronto Lupus Clinic (enrolled within 18 mos of diagnosis) were investigated. No time interval > 18 months was allowed between consecutive visits. A monophasic course was defined as Systemic Lupus Erythematosus Disease Activity Index 2000 = 0 (serology excluded), achieved within 5 years since enrollment and maintained for ≥ 10 years. Descriptive statistics were used.Results.Of 267 inception patients, 27 (10.1%) achieved prolonged clinical remission (≥ 10 yrs) and 20 (7.5%) sustained remission for the entire followup (18 yrs on average). Twelve patients were receiving no maintenance treatment 10 years after achieving remission. Clinical manifestations at diagnosis (apart from skin and musculoskeletal involvement) included 25% in each of central nervous system involvement and lupus nephritis (LN). Half the patients were serologically active. Ten years after achieving remission, two-thirds of the patients had discontinued glucocorticosteroids; the remaining were treated with 5 mg/day on average. Seven patients relapsed after 10 years, 4 with arthritis, 2 LN, and 1 catastrophic antiphospholipid syndrome.Conclusion.A monophasic disease course was observed in 7.5% in this inception cohort. Patients sustained remission for 18 years on average, eventually without medications. Further study of such patients may provide unique pathophysiologic insights for SLE.

BackgroundCD226, an activating receptor expressed on the surface of natural killer (NK) cells and T cells, is also seen on B cells and CD226 polymorphism is associated with systemic lupus erythematosus (SLE). Because the specific roles of CD226+ B cells in SLE are still unknown, we investigated the association of CD226+ B cells with SLE.MethodsWe measured CD226 expression on B cells and its subsets using flow cytometry in 48 SLE patients and 24 healthy controls (HCs). We assessed the relationships between CD226+ B cells and SLE Disease Activity Index 2000 (SLEDAI-2K), clinical manifestations, laboratory data, and prognosis after 12 months.ResultsThe proportions of CD226+ cells in whole B cells and all its subsets were significantly higher in SLE patients than HCs. In SLE patients, the proportions of CD226+ B cells and CD226+ switched-memory (SM) B cells were significantly correlated with SLEDAI-2K scores and anti-dsDNA antibody titers, and negatively correlated with serum complement levels. Moreover, basal percentages of CD226+ B cells and CD226+ SM B cells were low in patients who were in Lupus Low Disease Activity State after 12 months. In patients with renal involvement, the proportion of CD226+ B cells increased. Additionally, the proportion of CD226+ B cells was higher in patients who were not in complete renal remission after 12 months.ConclusionsIncreased proportion of CD226+ B cells was associated with disease activity and prognosis of SLE. CD226+ B cells may be a useful biomarker for the management of SLE.

The aim was to explore possible correlations of antibodies to extractable nuclear antigens (ENA) with clinical manifestations and disease activity indices in systemic lupus erythematosus (SLE) patients. A total of 70 consecutive SLE patients (64 females) were included. Disease activity was assessed by SLE activity index (SLEDAI), and British Isles Lupus Assessment Group (BILAG). Anti-Ro/SSA correlated positively with, headache (r=0.24, p=0.04), blurring of vision (r=0.25, p=0.03) and SLEDAI (r=0.25, p=0.04) and negatively with C3 (r=–0.35, p=0.003). Anti-Ro/SSA correlated with anti La/SSB antibodies (r=0.69, p<0.001), but not with anti-DNA, anti-RNP and anti-Sm antibodies. Anti-La/SSB antibodies correlated with headache (r=0.26, p=0.03), SLEDAI (r=0.25, p=0.03) and negatively with C3 (r=–0.34, p=0.004). Anti-La/SSB did not correlate with anti-RNP or anti-Sm antibodies. Anti-Sm antibodies correlated with disease duration (r=0.34, p=0.003), 24 hours urinary proteins (r=0.31, p=0.008), SLEDAI (r=0.31, p=0.009), BILAG renal score (r=0.29, p=0.02) and negatively with age at onset (r=–0.27, p=0.02), WBCs (r=–0.29, p=0.014) and C4 (r=–0.25, p=0.049). In multivariate analyses, anti-Ro/SSA antibodies remained associated with headache, blurring of vision and C3 and anti-La/SSB antibodies remained associated with C3 and with headache. Anti-Sm antibodies were independently associated with disease duration and total SLEDAI scores, while anti-RNP antibodies remained significantly associated with BILAG mucocutaneous scores only. Antibodies to ENAs are associated with clinical aspects of SLE and may play a role in the assessment of disease activity. Insight into these ENAs may lead to new approaches to diagnostic testing, accurate evaluation of disease activity and lead to target approach for SLE.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a wide range of clinical manifestations. Numerous observations and surveys of patients have shown that the most common symptom of SLE is fatigue complaints in 51 to 90% of patients.Objective: to determine the significance of fatigue in the general health status of RENAISSANCE cohort patients with SLE who were hospitalized in the Clinic, V.A. Nasonova Research Institute of Rheumatology.Patients and methods. The investigation included SLE patients aged 18 years and older who met the 2012 SLICC criteria. The standard examination accepted in the management of patients with SLE was made. Disease activity was determined by SLEDAI-2K; irreversible lesions in various organs were identified using the SLICC damage index. The SF-36 and the LupusQoL questionnaires were used to assess health-related quality of life (HRQOL) and the FACIT-Fatigue scale was applied to measure fatigue.Results and discussion. The investigation enrolled 328 patients, mainly women (91%); the mean age was 34.4±11.5 years; the duration of the disease was 106.3±97.9 months. In this group, moderate and high disease activities (SLEDAI-2K scores of 6–10 and 11–19, respectively) were observed at approximately the same frequency. At the time of inclusion, more than half (56.5%) of the patients already had various irreversible organ lesions. At Visit 1, the FACIT-Fatigue scale showed that fatigue was present in 148 (45%) of the 328 patients. According to the presence of fatigue, the patients were divided into two groups. Group 1 included 148 patients with fatigue; Group 2 consisted of 180 patients without fatigue. The Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and anti-DNA antibody levels were significantly higher in the fatigue group (p=0.01 and p=0.02, respectively); the patients also had decreased HRQOL according to 7 LupusQol domains (p<0.001). The patients with fatigue were significantly more likely to receive intravenous glucocorticoids and rituximab. At 12 months after the start of treatment, the patients with fatigue were found to have a statistically significant reduction in disease activity, as well as normalization of anti-DNA antibody levels, improvements in HRQOL according to the LupusQol domains, and less severity of fatigue according to the FACIT-Fatigue scale.Conclusion. Fatigue was detected in almost half (45–53%) of SLE patients. It is associated with a higher disease activity by SLEDAI-2K and with a high anti-DNA antibody level. The patients with fatigue are observed to have an obvious worsening of HRQOL according to all LupusQol domains.

Introduction. In spite of the growing number of reports on the study of anti-nucleosome and anti-C1q antibodies, there are still controversies on their significance as disease activity markers in patients with systemic lupus erythematosus (SLE) and their use in everyday clinical practice. Objective. Our aim was to assess the presence of anti-dsDNA, anti-nucleosome and anti-C1q antibodies in SLE patients, as well as to establish their sensitivity, specificity, positive and negative predictive value, and their correlation with SLE and lupus nephritis clinical activity. Methods. The study enrolled 85 patients aged 45.3?9.7 years on the average, with SLE of average duration 10.37?7.99 years, hospitalized at the Institute ?Niska Banja? during 2011, and 30 healthy individuals as controls. Disease activity was assessed using Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). In all examinees the levels of anti-dsDNA, anti-nucleosome and anti-C1q antibodies were measured using the ELISA method with Alegria Test Strips Orgentec (Germany). Results. Patients with active lupus nephritis had a higher presence of anti-C1q antibodies and higher co-positivity of anti-dsDNA, anti-nucleosome, and anti-C1q antibodies compared to those with inactive lupus nephritis (77.77% vs. 21.74%; p<0.01). SLE patients with SLEDAI ?11 had a higher presence of antinucleosome (93.75% vs. 64.15%; p<0.01) and anti-C1q antibodies (46.87% vs. 22.64%; p<0.05), as well as a higher mean level of anti-nucleosome antibodies (107.79?83.46 U/ml vs. 57.81?63.15 U/ml; p<0.05), compared to those with SLEDAI of 0-10. There was a positive correlation between the SLEDAI and the level of anti-dsDNA (r=0.290; p<0.01), anti-nucleosome (r=0.443; p<0.001), and anti-C1q antibodies (r=0.382; p<0.001). Only anti-C1q antibodies demonstrated correlation with proteinuria (r=0.445; p<0.001). Conclusion. Anti-nucleosome and anti-C1q antibodies demonstrated association with SLE and lupus nephritis activity, suggesting their potential usefulness in making predictions about lupus nephritis and assessment of disease activity.

Objective.Syndecan-1 (SDC-1) is a major constituent of the endothelial glycocalyx, which plays a role in maintaining vascular homeostasis and functions as a glomerular filtration barrier. SDC-1 is readily shed into the blood under various conditions, but the clinical implication of circulating SDC-1 in patients with systemic lupus erythematosus (SLE) remains unclear. We aimed to investigate the association of serum SDC-1 level with certain clinical manifestations of SLE.Methods.We measured serum SDC-1 levels by ELISA in 111 patients with SLE, 18 with rheumatoid arthritis (RA), and 20 healthy subjects, and investigated its association with clinical manifestations and laboratory variables.Results.Serum SDC-1 levels were higher in patients with SLE than in those with RA and healthy controls (both p < 0.001) and were positively correlated with SLE Disease Activity Index (SLEDAI; r = 0.367, p < 0.001) and anti-dsDNA antibody level (r = 0.259, p = 0.007), but inversely correlated with serum C3 and CH50 levels (r = −0.305, p = 0.001 and r = −0.244, p = 0.012). Patients with active nephritis had higher serum SDC-1 levels than patients with inactive nephritis and those without nephritis (both p < 0.001). In addition, serum SDC-1 levels were correlated with renal SLEDAI score (r = 0.540, p < 0.001) and excretion of proteinuria as measured by spot urine protein/creatinine ratio (r = 0.538, p < 0.001). In 14 patients with lupus nephritis (LN) whose serum samples were obtained at the time of renal biopsy, there was a positive correlation between serum SDC-1 levels and activity index (r = 0.632, p = 0.015).Conclusion.Serum SDC-1 levels are increased in SLE patients with nephritis, indicating that SDC-1 might be a useful serum biomarker for active LN.
