Implication of plasma gelsolin in systemic lupus erythematosus patients

Abstract Background Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with more than one organ involvement. Kidney is the foremost commonly affected one. Gelsolin is a protein that induces depolymerization of actin filaments thus preventing downstream stimulation of inflammatory reactions. The aim of this work was to detect the relation of plasma gelsolin to SLE disease activity and severity indices in order to find out if plasma gelsolin could be used as a biomarker of the disease. This study was conducted on 50 SLE female patients and 30 matched control. SLE disease activity Index (SLEDAI) and SLE damage index (SDI) were assessed. All lupus nephritis (LN) patients were subjected to an ultrasound-guided kidney biopsy. Plasma gelsolin level was measured. Results The mean age of the patients was 38.5 ± 6.3 years (26–51 years) with median disease duration of 5 (3–9.3) years. Eighteen patients had LN, 11 had cardiac manifestations and 12 had chest manifestations. The mean SLEDAI was 13.1 ± 4.5 (4–22) and the median SDI was 2 (1–3). Plasma gelsolin level was significantly lower in SLE patients (74.9 mg/l; 57.5–98.8 mg/l) compared to control (801.5 mg/l; 225–1008.3 mg/l) (p < 0.001). There were significant negative correlations of gelsolin levels with anti-ds DNA (r = − 0.63, p < 0.001), SLEDAI (r = − 0.79, p < 0.001), and SDI (r = − 0.74, p = 0.001). Plasma gelsolin level was significantly lower in SLE patients with high/very high activity grades compared to those with low and moderate (p = 0.007 and p < 0.001 respectively). A gelsolin level of ≤ 78.95 mg/l significantly predicted renal affection (p < 0.001), with a sensitivity of 100%, specificity 71.9%, and a positive predictive value 66.7%. Conclusion A decreased gelsolin level is associated with disease activity in SLE patients. Plasma gelsolin was well related to disease activity and severity with a high predictive value for renal affection comparable to anti-ds DNA titre. Plasma gelsolin is a potentially important predictive biomarker for SLE and LN.

Background:Systemic lupus erythematosus is an autoimmune disease with a major impact on patient’s quality of life.Objectives:To evaluate patient’s attitude toward early disease and factors that influence it.Methods:Performed case-control study included SLE patients that fulfilled SLICC, 2012 classification criteria. The research included two groups of patients: early SLE – 1stgroup (disease duration ≤24 months) and non-early SLE – 2ndgroup control (disease duration >24 months). The pattern of the disease activity was assessed by patient global assessment (PGA), Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and Systemic Lupus Activity Measure (SLAM), for SLE activity, SLICC/ACR Damage Index (DI) for disease irreversible changes and SF-8 for the Quality of Life (QoL).Results:A total of 101 SLE patients with 34 in the 1stgroup (early SLE) and 67 in the 2ndgroup (non-early SLE) was analyzed. The disease activity showed high disease activity in both groups by SLEDAI (7,02±4,16 and 6,26±4,43 points, p>0,05) and SLAM (7,47±4,40 and 7,31±4,10 points, p>0,05) such as (46,97±19,39 vs 47,98±22,41 points). The QoL was appreciated as low, by both components (mental and physical), in groups. The damage index was higher in the 2nd group (0,23±0,43 and 1,07±1,29, p<0,001), which can be explained by the development of irreversible changes with the increase of disease duration.The PGA in early SLE was influenced by subjective symptoms contained in SLAM index (r=0,48, p<0,05), such as fatigue and depression, and the level of the quality of life (r=0,65, p<0,001). Meantime, PGA in patients with longer disease duration (>2 years), was influenced by the presence of organ damage by SLICC/ACR DI (0,23, p<0,05) and objective findings of the disease activity contained in SLEDAI (r=0,33, p<0,005) and SLAM (0,44, p<0,001).Conclusion:The disease recognition in patients with early SLE was determined by subjective and psycho-emotional signs, while in patients with longer disease duration it was influenced by organ damage and complications.References:no referencesDisclosure of Interests:None declared

Lupus Disease Activity

Objective.Adjusted mean Systemic Lupus Erythematosus Disease Activity Index (SLEDAI; AMS) measures lupus disease activity over time. Our aim was to determine optimal visit frequency for calculating AMS.Methods.Patients followed monthly for 12 consecutive visits were included. AMS was calculated using all of the SLEDAI 2000 (AMSGOLD using all 12 visits), only quarterly visits (AMS3, using visits 3 months apart), semiannual visits (AMS6, using first, middle, and last visits only), and annual visits (AMS12, using only the first and last visits). Comparisons of AMS3, AMS6, and AMS12 with AMSGOLD are made using descriptive statistics.Results.Seventy-eight patients were included (92% women, mean age at SLE diagnosis 30.1 yrs and at study start 46.2 yrs). The mean (SD) AMSGOLD for the entire year was 2.05 (1.66), for AMS3 1.99 (1.65), for AMS6 2.12 (1.87), and for AMS12 2.08 (1.83). Mean (SD) of the absolute differences with AMSGOLD: for AMS3 0.29 (0.33), for AMS6 0.45 (0.59), and for AMS12 0.61 (0.58). Differences that were < 0.5 were considered minimal while those ≥ 1 were deemed important. Comparing AMSGOLD to AMS3, 82% of the differences were minimal and 3% were important. When comparing to AMS6, 68% were minimal and 10% were important, while comparing to AMS12, 50% were minimal and 21% were important.Conclusion.Usual clinic visits occurring quarterly offer a good estimation of disease activity over a 1-year period and are preferred over semiannual and annual visits.

Objective To evaluate the reliability, validity, feasibility and psychometric performance of the Lupus Impact Tracker (LIT) as a patient reported outcome (PRO) measure tool in pediatric systemic lupus erythematosus (pSLE). Methods This is a prospective, observational, pilot study where patients aged between 12 and 25 years, fulfilling the 1997 ACR classification criteria for SLE, were enrolled. Over 3 consecutive, routine, clinical visits, the patients completed the LIT alongside the Patient-Reported Outcomes Measurement Information System-Short Forms (PROMIS-SFs), Childhood Health Assessment Questionnaire (CHAQ). Rheumatologists completed the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC-ACR) Damage Index. Demographic, clinical and laboratory data were also collected. Results Of 46 patients enrolled, 38 patients completed 2 visits and 31 completed all 3 visits. Seventy-eight percent were female, 33% African American, 28% Asian, 15% Caucasian and 17% Hispanic. The mean (SD) age was 17.2 (2.7) years, with a mean (SD) disease duration of 4.6 (3.1) years. The mean (SD) SLEDAI-2K at enrollment was 3.54 (2.96). In the 38 patients who completed two or more visits, intra-class correlation coefficient and Cronbach alpha were calculated to be 0.70 and 0.91 respectively, signifying good reliability of LIT. The LIT showed positive correlation with CHAQ-Disability Index and majority of the PROMIS-SFs parameters. Construct validity was established against clinical disease activity (SLEDAI-2K). Conclusion The preliminary results indicate that the LIT is a reliable and valid instrument to capture PRO in p-SLE. Prospective validation with a larger, multicenter cohort is the next step.

Objective.To identify the effect of disease activity and damage, measured by validated indices, on mortality and damage accrual, in order to inform upcoming Canadian systemic lupus erythematosus (SLE) recommendations.Methods.Following GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology to fill in evidence-to-decision tables to create recommendations for “minimal investigations needed to monitor SLE patients at baseline and subsequent visits,” a systematic literature review was performed. The effect of disease activity and damage, measured by validated metrics, on mortality and damage was systematically reviewed, with metaanalyses performed when available.Results.A title/abstract screen of 5599 articles identified 816 articles for full paper review, with 102 meeting inclusion criteria and 53 with extractable data. Thirty-three articles describing outcomes related to disease activity and 20 articles related to damage were identified. Mortality was associated with higher SLE Disease Activity Index-2000 scores in 6 studies (HR 1.14, 95% CI 1.06–1.22) and higher Systemic Lupus International Collaborating Clinics/ACR Damage Index scores in 6 studies (HR 1.53, 95% CI 1.28–1.83). Higher SLE Activity Measure scores were associated with increased risk of damage in 3 studies (OR 1.06, 95% CI 1.04–1.08). British Isles Lupus Assessment Group was associated with mortality in 1 study with HR of 1.15.Conclusion.Active SLE disease and damage are associated with and predict greater mortality and damage. The use of validated disease activity and damage metrics is important in the assessment of disease activity and damage and will inform upcoming Canadian recommendations for the assessment of SLE.

Media Thickness

Objective.Microparticles (MP) are small extracellular vesicles present in body fluids. MP originate from different cellular lineages, principally from platelets in blood, and may expose phosphatidylserine (PS). In systemic lupus erythematosus (SLE), MP harbor immunoglobulin G (IgG), thereby forming MP-containing immune complexes (mpIC). We aimed to verify an association between SLE disease activity, damage, and surrogate markers of atherosclerosis and MP harboring IgG, taking into account the platelet origin and PS exposure of MP.Methods.MP expressing surface IgG, platelet antigen (CD41+), and PS were quantified using flow cytometry in plasma of 191 women with SLE. Carotid ultrasounds (US) were available in 113 patients. Spearman correlation analysis was used to analyze whether levels of MP were associated with the following outcomes: SLE Disease Activity Index 2000 (SLEDAI-2K), Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), and carotid US plaques and intima-media thickness (CIMT) as surrogates for vascular damage.Results.We found CD41+ MP harboring IgG present in SLE. A positive correlation was found between SLEDAI-2K and levels of CD41+ MP harboring IgG and exposing (p = 0.027) and non-exposing PS (p = 0.001). Conversely, SDI (p = 0.024) and CIMT (p = 0.016) correlated with concentrations of CD41− MP harboring IgG and exposing PS. Associations were independent of low-density lipoprotein cholesterol level, body mass index, and antimalarial drug use.Conclusion.Different subtypes of mpIC are produced in SLE and are associated with distinct clinical characteristics such as disease activity and vascular damage. The assessment of MP subtypes might serve for the design of predictive markers of disease activity and vascular damage in patients.

Background:Distinguishing primary NPSLE (neuropsychiatric systemic lupus erythematosus) from secondary causes remains challenging (1). Attribution models were developed in order to aim clinicians in correct classification of NPSLE cases (2).Objectives:To investigate the prevalence of primary NPSLE manifestations assigned with Italian model of attribution (2).Methods:We retrospectively assessed clinical details of 164 patients with SLE classified with 2012 SLICC (Systemic Lupus International Collaborating Clinics) classification criteria, 21 were excluded due to incomplete information. Data was gathered with a questionnaire comprising demographics, medical history, laboratory results (concentrations of antibodies against double stranded DNA – anti-dsDNA, complement components C3 and C4), disease activity measured with Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and Physician Global Assessment (PGA) and damage determined with SLICC/ACR (American College of Rheumatology) Damage Index (SDI). Neuropsychiatric manifestations were categorized in accordance with 1999 ACR glossary and attribution of manifestations was performed with the use of Italian model with the score ≥7 out of 10 points enabling assignment to primary NPSLE group (2). Statistical analysis was conducted with Statistica v.13.3 using Mann-Whitney U, chi-square and Fisher exact test.Results:We encountered 155 NP manifestations in our cohort and 52 (34%) were attributed to SLE. Characteristics of the study groups are presented in Table 1. Exact manifestations and their attribution rates are presented on Graph 1. Patients with attributable NPSLE were younger, had earlier disease onset, presented higher disease activity, lower damage accrual without taking NP damage into account and more often had increased anti-dsDNA serum concentration.Table 1.Demographic and laboratory characteristics with disease activity and damage of the study groups, N(%) or mean(±SD).CharacteristicPatients with attributed NPSLE manifestationsPatients without attributed NPSLE manifestationsPatients34 (23.8%)109 (76.2%)Sex, female30 (88.2%)102 (93.6%)Age (years)37.6 (±11.7)44.3 (±13.9)*Age of disease onset (years)32.5 (±11.4)37.6 (±12.6)*Disease duration (years)5.1 (±4.1)6.8 (±5.6)SLEDAI-2K29.2 (±10.7)12.2 (±8.1)*patients with clinically active disease (defined as SLEDAI-2K≥6 in clinical manifestations)34 (100%)93 (85.3%)*SLEDAI-2K without NP manifestations14.8 (±8.4)11.0 (±6.7)*PGA2.1 (±1.0)1.2 (±1.0)*SDI0.5 (±0.8)0.7 (±1.1)SDI without NP damage0.3 (±0.6)0.7 (±1.1)*low C3/C4 complement component concentration in serum21 (61.8%)55 (50.4%)elevated anti-dsDNA autoantibody concentration in serum27 (79.4%)55 (50.4%)*NPSLE – neuropsychiatric systemic lupus erythematosus, SLEDAI-2K – Systemic Lupus Erythematosus Disease Activity Index version 2000, PGA – physician global assessment, SDI – SLICC/ACR (Systemic Lupus International Collaborating Clinics/American College of Rheumatology) Damage Index*p<0,05, Mann-Whitney U, χ2or Fisher’s exact test, as appropriateConclusion:Primary NP manifestations in patients with SLE occur mainly in young patients with high disease activity.

Objectives To quantify signal abnormalities in the hippocampus (Hsig) of patients with systemic lupus erythematosus (SLE) and to determine if Hsig predict hippocampal atrophy (HA) in SLE. Methods We included all SLE patients and healthy age- and sex-matched individuals with two magnetic resonance imaging (MRI) scans performed with a minimum of 1 year interval. All individuals underwent a standardized neuropsychological evaluation. Individual results were converted into standard scores and compared to normative data. SLE patients were additionally assessed for disease activity (SLE Disease Activity Index (SLEDAI)), damage (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)), and the presence of antiphospholipid antibodies. MRI was performed on an Elscint 2 T scanner and T1 inversion recovery and T2 coronal images were used for analysis. Volumetric (HV) and signal quantification (Hsig) were determined by standardized protocols. Results We included 54 SLE patients (48 women; mean age 32.2 ± 10.56 years). Hsig were found at study entry in 15 (45.5%) patients. Hsig in the body and tail of non-atrophic hippocampi correlated with progression of volume loss during the follow-up period ( r = 0.8, p < 0.001). The presence of Hsig in the head of atrophic hippocampi correlated with progression of HA ( r = 0.73, p = 0.005) during the same period. No correlation of Hsig and disease activity or prednisone dose was observed. Conclusion HA is frequently observed in SLE patients and volume loss is progressive in a subgroup of patients. The evaluation of Hsig is an easy tool to determine patients that may have progressive hippocampal volume loss and should be followed more closely with MRI and cognitive evaluation.

Outcomes included increase in Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), flare, achieving low disease activity (LDA), adjusted mean Systemic Lupus Erythematosus Disease Activity Index 2000, cumulative doses of steroids (CMS), and AM-related retinal toxicity. Regression analysis models were constructed to identify predictors of the outcomes.Results.There were 459 patients identified: 236 (51.4%) in group A, 88 (19.2%) in group B, and 135 (29.4%) in group C. The changes in SDI, flare event, and CMS were significantly lower in group A, which more often achieved LDA. Multivariable analysis revealed that the patients in group A had a lower risk of increasing SDI and were more likely to achieve LDA at Year 5 compared to the patients in group C. Patients taking AM had lower CMS over the 5 years of followup. There was only 1 patient with AM-related retinal toxicity in each group.Conclusion.More consistent use of an AM over the first 5 years of SLE is associated with better outcomes.

Background The emerging role of vitamin D in immunology and autoimmune disorders has been a worldwide interest in the last decade. Systemic lupus erythematosus (SLE) patients are particularly at a delicate position predisposing them to suffer from vitamin D deficiency due to the multiple risk factors accompanying the disease. Whether vitamin D deficiency is also involved as a risk factor for developing SLE and affecting its course is a considerable concern. Objectives The objective of this study was to estimate the prevalence of vitamin D deficiency in SLE patients and its relation to disease. MATERIALS AND METHODS: In our observational cross-sectional study, serum levels of vitamin D [25(OH)D] in 60 SLE patients and 30 age- and sex-matched healthy controls were assessed and estimated for deficiency and insufficiency at 10 and 30 ng/mL, respectively. Disease activity was evaluated by SLE disease activity index (SLEDAI), irreversible organ damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI), and severity by Severity of Disease Index. Fatigue was measured by visual analog scale. Results Significantly lower levels of 25(OH)D were found in SLE patients (17.6 ± 6.9 ng/mL) in comparison to controls (79.0 ± 28.7 ng/mL), with a statistically high significant difference ( t = -11.2, P < 0.001). High prevalence of vitamin D insufficiency and deficiency was detected as 73.3% and 23.3%, respectively. Vitamin D had a highly significant negative correlation with SLEDAI ( r = -0.495, P < 0.001), SLICC ( r = -0.431, P < 0.05), and fatigue ( r = -0.436, P < 0.05). Conclusion Vitamin D deficiency and insufficiency were found to be prevalent in SLE patients in our study and related to disease activity and fatigue. If needed, routine screening and consequent repletion of vitamin D are recommended in SLE patients. Restoring adequate vitamin D levels in SLE patients should be more explored as a potential yet simple measure to their usual management to improve their condition.

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.
