The frequency and characteristics of ultrasonographic ankle joint involvement in systemic lupus erythematosus: A prospective cross-sectional single-center study.

The involvement of ankles in systemic lupus erythematosus (SLE) has not been widely studied. The aim of our prospective study was to determine the characteristics of the ankle joint and tendon involvement in SLE using ultrasound (US) as an imaging modality. Sixty consecutive patients with SLE underwent a detailed clinical evaluation and US examination. Gray-scale and power Doppler US of the bilateral tibiotalar (TT) joints, subtalar (ST) joints, and ankle tendons were performed using a multiplanar scanning technique. Joint effusion, synovitis, tenosynovitis, enthesitis, and vascularization were assessed according to the OMERACT recommendations. The Total Ankle Ultrasound Score (TAUSS) was calculated as the sum of the grades of joint effusion and synovial hypertrophy for both TT and ST joints bilaterally (ranging from 0–24) and power Doppler activity was assessed separately. Finally, US findings were correlated with physical evaluation, laboratory parameters, and SLE activity scores. US ankle joint involvement was present in 32/60 (53.3%) patients. TT joints were affected in 26 (43.3%) and ST joints in 16 (26.7%) patients. Thirteen (21.7%) patients had US tendons and/or enthesal involvement. TT joint effusion was the most frequent finding, present in 55/240 (22.9%) examined joints, followed by synovial hypertrophy detected in 18/240 (7.5%) joints. The median (interquartile range; range) TAUSS of the US-affected joints was 1 (0–2; range 1–10). There were no significant correlations between US findings and inflammatory parameters or serological parameters of disease activity, but we found a weak positive correlation between TAUSS and the European Consensus Lupus Activity Measurement (r = 0.281, P = .029). This study revealed a high prevalence of pathological US ankle changes in patients with SLE and a positive correlation between ankle US involvement and disease activity score (European Consensus Lupus Activity Measurement).

Anti-RNP Antibody: A Potential Novel Predictor for Osteonecrosis in Systemic Lupus Erythematosus.

ObjectiveTo explore risk factors for developing osteonecrosis in patients with systemic lupus erythematosus (SLE).MethodsTwenty-six SLE patients with osteonecrosis from January 2018 to December 2019 were described. Fifty SLE patients without osteonecrosis were selected as controls from the SLE database (total 2,680) of our hospital during the same period. Clinical manifestations and laboratory tests were recorded and analyzed, especially antibodies. Univariate and multivariate analyses were used to evaluate possible associated risk factors.ResultsTwenty-six (3 male, 23 female) SLE patients with osteonecrosis were confirmed by X-ray and magnetic resonance imaging. The median course from SLE onset to osteonecrosis onset was 45 (range 2–302) months. Seven (27%) patients had a single joint involved and 19 (73%) patients had two or more joints involved. Besides, the incidence of femoral head osteonecrosis (FHON), knee ON, and humerus head ON were 85% (22/26), 27% (7/26), and 12%(3/26), respectively. The multivariate logistic regression analysis showed that the score of European Consensus Lupus Activity Measurement (ECLAM) at SLE onset [odds ratio (OR) 1.37; 95% confidence interval (CI) 1.07–1.75], a cumulative dose of prednisone above 10 g (OR 15.49; 95% CI 3.38–84.61), and positive of independent anti-RNP antibodies (OR 3.35; 95% CI 0.80–10.73) were significantly associated with osteonecrosis in SLE.ConclusionThe score of ECLAM at SLE onset, a cumulative dose of prednisone above 10 g, and positive anti-RNP antibodies are associated with osteonecrosis in SLE. Herein, we reported for the first time that anti-RNP antibodies were associated with osteonecrosis in SLE patients and might be a novel predictor.

Living with Systematic Lupus Erythematosus: A Profile of Young Female Patients.

The aim is to describe a profile of systemic lupus erythematosus (SLE) patient (socio-demographic data, course of disease, health status, and health care utilization, SLE impact on their life, SLE awareness) and to explore the association of patient’s perspective with clinical indicators. Adult patients diagnosed by SLE were recruited in outpatient clinics (n = 76, 88% female, data collected in 2012–2016, Slovakia). The association of patients’ perspective (SLE status, health complaints during remission, SLE impact, hospitalizations) with clinical activity (European Consensus Lupus Activity Measurement Index—ECLAM) and inflammatory marker (erythrocyte sedimentation rate—ESR) was assessed by t-test for independent variables and one-way ANOVA. Almost 17.9% of patients reported relapse. During remission, they mostly suffered fatigue and pain. Nearly all patients were on chronic pharmacological treatment. Most of the patients assessed SLE impact on their life as restrictive (56.9%) or very restrictive (23.1%). The most frequent source of information was their physician, and 67.2% reported that they have sufficient information about the disease and its treatment. Only the association of SLE status and hospitalization with clinical activity (ECLAM) and inflammatory marker (ESR) were confirmed. With recent improvements in diagnostics and therapy options, the prognosis for patients with SLE has improved. Nevertheless, the impact of this disease on all areas of a patient’s life is extensive.

Liver disease in systemic Lupus erythematodes - results of an explorative observational study

Systemic lupus erythematodes (SLE) represents an autoimmune disease with a highly variable clinical course affecting numerous organs. Hepatic manifestation seems to be rare. It is not clear whether hepatic disease in SLE is of any prognostic importance or whether it correlates with disease activity. Our patient cohort included 172 patients with proven SLE, all treated at Bogenhausen Hospital between 01.2009 and 12.2015. Retrospectively, all admissions as inpatients and outpatients were analyzed (n = 671; mean 3.9 per patient). Liver damage was diagnosed by evaluation of laboratory parameters on the basis of pathological liver enzymes and by imaging methods. Disease activity of SLE was calculated by using European Consensus Lupus Activity Measurement-(ECLAM-)Score. Additionally, parameters of SLE including disease duration, organ damage and immune suppressive medication and their possible association with hepatopathy were analyzed. Elevated liver parameters (ASAT, ALAT, GGT, AP) indicating liver damage were detectable in 109 patients (63.4 % of total population) demonstrating significant association with disease activity (on the basis of ECLAM-score, p < 0.001), duration of treatment, frequency of admissions (p < 0.01, respectively), number of used immunosuppressive agents (p < 0.018), increased blood sedimentation rate (p < 0.001) and reduction of serum complement (p < 0.03). Abnormal ultrasound findings of the liver (e. g., non-alcoholic fatty liver disease) were diagnosed in 19.8 %. Elevated liver parameters occur frequently in patients with SLE, especially in context with increased disease activity (on the basis of ECLAM-Score or intensified immunosuppressive therapy) and prolonged course of the disease. Liver enzymes should be obtained regularly in patients with SLE and, if necessary, further diagnostic steps should be initiated. Further prospective studies might clarify whether abnormal liver parameters must be included in activity indices to judge disease activity in SLE.

Early Lupus Project: one-year follow-up of an Italian cohort of patients with systemic lupus erythematosus of recent onset.

Objective To describe the clinical and serological features of a prospectively followed cohort of early diagnosed systemic lupus erythematosus (SLE) patients during a one-year follow-up period. Methods SLE patients with disease duration less than 12 months were consecutively enrolled in a multicentre, prospective study. At study entry and then every 6 months, a large panel of data was recorded. Results Of 260 patients enrolled, 185 had at least 12 months of follow-up; of these, 84.3% were female, 92.4% were Caucasians. Mean diagnostic delay was about 20 months; higher values of European Consensus Lupus Activity Measurement (ECLAM) and of organs/systems involved were both associated with shorter diagnostic delay. Clinical and serological parameters improved after study entry. However, patients' quality of life deteriorated and cardiovascular risk factors significantly increased. About one-third of patients with active disease at study entry went into remission (ECLAM = 0). Negative predictors for remission were: oral ulcers, arthritis, low C4, anti-SSB (Ro) antibodies and therapy with mycophenolate. There was a widespread use of glucocorticoids both at baseline and during follow-up. Conclusion Clinical symptoms and serological parameters improve during the first period after diagnosis. However, patients' quality of life deteriorates. The widespread use of glucocorticoids is probably the reason for the early significant increase of some cardiovascular risk factors.

Sensitivity analyses of four systemic lupus erythematosus disease activity indices in predicting the treatment changes in consecutive visits: a longitudinal study.

This study was conducted to assess the ability of the British Isles Lupus Assessment Group-2004 (BILAG-2004), the SLE Disease Activity Index-2K (SLEDAI-2K), the European Consensus Lupus Activity Measurement (ECLAM), and the Revised Systemic Lupus Activity Measure (SLAM-R) to detect the need to treatment change in daily clinical practice. One hundred and two patients with SLE were enrolled and followed up for 2 to 8months and visited at least 3 times. Physician Global Assessment, BILAG-2004, SLEDAI-2K, SLAM-R, and ECLAM, were calculated in every visit. Treatment change, dependent variable, was categorized as decrease/no change vs. increase. The aforementioned indices, independent variables, were compared to learn their ability in predicting the treatment change. The probability of treatment change was measured by generalized linear-mixed effect model (GLMM) and generalized estimating equations (GEE). Adjusted odds ratios were calculated. Predictive power of indices was compared by area under the curve (AUC) in plots of sensitivity vs. 1-specificity and application of receiver operating characteristic curves (ROC). BILAG-2004 and SLEDAI-2K had substantial correlation with treatment change. Among different GLMM models, BILAG-2004 followed by SLEDAI-2K showed the highest associations with treatment change. Among various GEE models, similar findings were observed. Also, these 2 indices had the highest sensitivity (the largest AUC) towards treatment change; BILAG-2004 (AUC = 0.779, 95% CI = 0.710-0.848, p = 0.001) and SLEDAI-2K (AUC = 0.771, 95% CI = 0.698-0.843, p = 0.001). BILAG-2004 followed by SLEDAI-2K had the highest predictability of treatment change.

Anti-nucleosome antibodies in systemic lupus erythematosus patients: Relation to anti-double stranded deoxyribonucleic acid and disease activity

Aim of the workTo measure the level of anti-nucleosome (anti-NCS) antibodies in systemic lupus erythematosus (SLE) patients and to evaluate their relation with anti-double stranded deoxyribonucleic acid (anti-dsDNA) antibodies and SLE disease activity. Patients and methods66 Egyptian SLE patients were investigated for the detection of anti-NCS antibodies and anti-dsDNA antibodies. Disease activity was assessed using the SLE disease activity index (SLEDAI) and the European consensus lupus activity measurement (ECLAM). ResultsThe median age of the patients was 25.5years (12–48years) and disease duration 3years (1month to 26years). anti-NCS antibody was found in 48 (72.7%) patients. Non-significant difference was found between both those positive or negative anti-NCS antibodies regarding the clinical features apart from fever (p=0.019). Lupus nephritis was present in 35/48(72.9%) of those with positive and in 11/18 (61.1%) of those with negative anti-NCS (p=0.35) A significant correlation was found between anti-NCS antibodies with SLEDAI (r=0.36, p=0.003) and ECLAM (r=0.29, p=0.019). No significant relation was found between anti-NCS antibodies and clinical features of SLE, apart from fatigue (r=0.3, p=0.015). A significant correlation with hypocomplementemia (C3 r=−0.37, p=0.002 and C4 r=−0.32, p=0.018) and anaemia (r=−0.32, p=0.009). anti-dsDNA antibodies were detected in 35(53%) SLE patients; 70.8% of those with positive and 5.6% of those with negative anti-NCS antibodies. ConclusionAnti-NCS antibodies could play a role in the pathogenesis of SLE and is related to disease activity. Its association with anti-dsDNA antibodies and its presence in those with negative anti-ds DNA may aid in the diagnosis of SLE.

A novel DNA/histone H4 peptide complex detects autoantibodies in systemic lupus erythematosus sera.

BackgroundThe detection of anti-dsDNA antibodies is critical for the diagnosis and follow-up of systemic lupus erythematosus (SLE) patients. The presently available assays are characterized by a non-optimal specificity (solid phase assays) or sensitivity (Crithidia Luciliae immunofluorescence test (CLIFT)). To overcome the limits of CLIFT and solid phase chromatin assays, we explored the diagnostic potential of an assay based on plasmid DNA containing a highly bent fragment of 211 bp from Crithidia Luciliae minicircles, complexed with histone peptides.MethodsElectrically neutral complexes of PK201/CAT plasmid (PK) DNA and histone 4 (H4) peptides were evaluated by electromobility shift assay. Complexes of H4 peptides and PK were absorbed to the solid phase to detect specific immunoglobulin G (IgG) in sera. Sera from 109 SLE patients, 100 normal healthy subjects, and 169 disease controls were tested.ResultsH4(14-34) containing the consensus sequence for DNA binding interacts with PK, retarding its migration. H4(14-34)/PK complexes were used to test sera by ELISA. Anti-H4-PK antibodies were detected in 56 % of SLE sera (more frequently in patients with skin or joint involvement) versus 5.9 % in disease controls; inhibition assays show that sera react with epitopes present on DNA or on the complex, not on the peptide. Antibody titer is correlated with European Consensus Lupus Activity Measurement (ECLAM) score and anti-complement component 1q (C1q) antibodies, negatively with C3 levels. Anti-H4-PK antibodies compared with CLIFT and solid phase dsDNA assays display moderate concordance.ConclusionsThe H4/PK assay is a simple and reliable test which is useful for the differential diagnosis and evaluation of disease activity in SLE patients.Electronic supplementary materialThe online version of this article (doi:10.1186/s13075-016-1117-8) contains supplementary material, which is available to authorized users.

SYSTEMIC LUPUS ERYTHEMATOSUS – DESCRIPTIVE STUDY OF 134 PATIENTS FROM A SINGLE CENTER

Introduction. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown origins with increasing prevalence worldwide. Lupus clinical and immunological features are complex and heterogeneous, but peculiar characteristics in different population were described. Aim. Description of specific clinical and biological features of SLE patients. Methods. 134 patients fulfilling the 2012 SLE Systemic Lupus International Collaborating Clinic criteria were enrolled. Baseline characteristics and biological features (such as sex, age, age at disease onset, disease duration, tobacco and alcohol habits, cardiovascular and fracture risk factors) were collected in all consenting patients prospectively included. Also, disease activity scores such as Systemic Lupus Activity Measure (SLAM), European Consensus Lupus Activity Measurement, Systemic Lupus Erythematosus Disease Activity Index, and accrual damage Systemic Lupus International Collaborating Clinics/American College of Rheumatology index were assessed when data needed for these scores were available. Results. A number of 134 SLE patients, majority of feminine sex (89.6%) were enrolled. The mean ± SD age at inclusion and onset age were 46.4 ± 12.9 years and 36.5 ± 12.2 years. 19.4% of patients included were current smokers. Regarding comorbidities, 8.5% associated diabetes and 41.8% hypertension. Anti-deoxyribonucleic acid antibodies were identified in the antecedents of only 50.4% of the searched cases; higher proportion of positivity was found for lupus anticoagulant, respectively 70.9%. Joint involvement was the most frequent clinical criterion used to sustain the lupus diagnosis (110 patients, 82.1%), while the hematological one the most frequent involvement at inclusion (50 patients, 37.3%). 67.9% of patients presented SLAM score results less or equal to 5 points, 10.4% results between 5 and 8 points, and 21.6% of more or equal to 8 points. The majority of patients enrolled were under corticosteroid treatment (109 patients, 81.3%) and also an important part was receiving Hydroxychloroquine (108 patients, 80.6%). Conclusion. In this cross-sectional study, we presented important data related to general characteristics, biological parameters, immunological features, disease scores, and treatment principles in a single-center sample of SLE patients.

Vitamin D Supplementation in Adolescents and Young Adults With Juvenile Systemic Lupus Erythematosus for Improvement in Disease Activity and Fatigue Scores: A Randomized, Double-Blind, Placebo-Controlled Trial.

Vitamin D has an important immunomodulatory effect, but there are no trials that directly address the boosting of serum levels of 25-hydroxyvitamin D (25[OH]D) in juvenile-onset systemic lupus erythematosus (SLE). The aim of this study was to evaluate the effect of vitamin D supplementation on disease activity and fatigue in juvenile-onset SLE. This study was a randomized, double-blind, placebo-controlled, 24-week trial. Forty juvenile-onset SLE patients were randomized (1:1) to receive oral cholecalciferol 50,000 IU/week (juvenile-onset SLE-VitD) or placebo (juvenile-onset SLE-PL). Medications remained stable throughout the study. Serum levels of 25(OH)D were measured using radioimmunoassay. Disease activity was assessed using the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and the European Consensus Lupus Activity Measurement (ECLAM). Fatigue was assessed using the Kids Fatigue Severity Scale (K-FSS). At baseline, groups were similar regarding age, body mass index, organ involvement, glucocorticoid dose, use of immunosuppressive drugs, SLEDAI, ECLAM, K-FSS, and levels of 25(OH)D. After 24 weeks, the mean level of 25(OH)D was higher in the juvenile-onset SLE-VitD group than in the juvenile-onset SLE-PL group (P < 0.001). At the end of the intervention, a significant improvement in SLEDAI (P = 0.010) and in ECLAM (P = 0.006) was observed in the juvenile-onset SLE-VitD group compared to the juvenile-onset SLE-PL group. Regarding fatigue evaluation, a reduction of fatigue related to social life score was found in the juvenile-onset SLE-VitD group compared to the juvenile-onset SLE-PL group (P = 0.008). Cholecalciferol was well tolerated with no serious adverse events. This study suggests that cholecalciferol supplementation for 24 weeks is effective in decreasing disease activity and improving fatigue in juvenile-onset SLE patients.

Illness perception in systemic lupus erythematosus patients: The roles of alexithymia and depression

ObjectiveAlexithymia and depressive mood have been described as important dimensions of several medical diseases. Systemic lupus erythematosus is a chronic condition characterized by unpredictable clinical manifestations. The relationships between alexithymia, depression, and illness perception were examined in systemic lupus erythematosus patients. The interrelationships between psychological factors, such as alexithymia and depressive mood, were explored in systemic lupus erythematosus patients, and associations between these factors and illness perception in SLE were examined. We hypothesized that alexithymia and negative perceptions of illness would be associated in SLE patients, and depression would mediate this relationship. MethodsSubjects were 100 consecutive systemic lupus erythematosus patients attending the outpatient clinic at the University of Pisa rheumatology unit. They completed the Toronto Alexithymia Scale, Beck Depression Inventory, and Revised Illness Perceptions Questionnaire. Clinical variables were measured, disease activity was evaluated using the European Consensus Lupus Activity Measure, and damage was assessed using the Systemic Lupus International Collaborative Clinics/American College of Rheumatology Damage Index. ResultsThere were no associations between clinical variables, alexithymia, and depression. The results highlight the existence of significant links between alexithymia and illness perception for systemic lupus erythematosus patients. Moreover, our data suggest that some of these links are mediated by depression, which is the direct predictor of different aspects of perceived health. ConclusionOur findings suggest that studying the role of psychological factors, such as alexithymia and depression, may contribute to a more comprehensive perspective of systemic lupus erythematosus, including their impact on patients' beliefs about treatment effectiveness and emotional adaptation to chronic disease.

Dissecting the damage in Northern Greek patients with childhood-onset systemic lupus erythematosus: a retrospective cohort study.

The improved survival of childhood-onset systemic lupus erythematosus (cSLE) has resulted in longer patients' exposure to disease inflammation, medications and/or comorbid diseases, which can all contribute to the development of organ damage. The aim of this study was to assess the evolution of damage accrual in cSLE patients overtime and investigate for predisposing factors. Disease characteristics and treatment in 47 Northern Greek Caucasian cSLE patients were retrospectively reviewed. The Systemic Lupus International Collaboration Clinics/American College of Rheumatology Damage Index (SDI) was used for damage assessment and the European Consensus Lupus Activity Measurement (ECLAM) to monitor cSLE activity. After a median disease duration of 7.4years, 17/47 patients (36%) had developed damage (SDI>0). The most frequent domains damaged were the ocular (41%), neuropsychiatric (35%) and peripheral vascular (35%) one. Peripheral vascular and neuropsychiatric damage was seen more frequently during the first 5years of the disease. Longer exposure to azathioprine was associated with higher SDI at the end of follow-up (β=0.008 for every additional month of use, p=0.041). The mean annual flare frequency was associated with a shorter time interval until the development of the first damage (hazard's ratio, HR 2.38 for each unit of increase, p=0.018), while hydroxychloroquine use was associated with longer time interval (HR 0.19, p=0.007). The lower rates of damage accrual in this study compared to other cohorts might be due to milder disease phenotype in Greek Caucasian cSLE patients, prompt diagnosis and effective disease control. Damage was noticed early in the disease course, and one-third of patients had an SDI>0 at study completion. Disease flares and a severe disease course leading to prolonged use of immunosuppressives were significant risk factors, while hydroxychloroquine use was protective against cSLE damage accrual.

Systemic Lupus Erythematosus with and without Anti-dsDNA Antibodies: Analysis from a Large Monocentric Cohort.

Objectives. The anti-dsDNA antibodies are a marker for Systemic Lupus Erythematosus (SLE) and 70–98% of patients test positive. We evaluated the demographic, clinical, laboratory, and therapeutical features of a monocentric SLE cohort according to the anti-dsDNA status. Methods. We identified three groups: anti-dsDNA + (persistent positivity); anti-dsDNA ± (initial positivity and subsequent negativity during disease course); anti-dsDNA − (persistent negativity). Disease activity was assessed by the European Consensus Lupus Activity Measurement (ECLAM). Results. We evaluated 393 patients (anti-dsDNA +: 62.3%; anti-dsDNA ±: 13.3%; anti-dsDNA −: 24.4%). The renal involvement was significantly more frequent in anti-dsDNA + (30.2%), compared with anti-dsDNA ± and anti-dsDNA − (21.1% and 18.7%, resp.; P = 0.001). Serositis resulted significantly more frequent in anti-dsDNA − (82.3%) compared to anti-dsDNA + and anti-dsDNA ± (20.8% and 13.4%, resp.; P < 0.0001). The reduction of C4 serum levels was identified significantly more frequently in anti-dsDNA + and anti-dsDNA ± (40.0% and 44.2%, resp.) compared with anti-dsDNA − (21.8%, P = 0.005). We did not identify significant differences in the mean ECLAM values before and after modification of anti-dsDNA status (P = 0.7). Conclusion. Anti-dsDNA status influences the clinical and immunological features of SLE patients. Nonetheless, it does not appear to affect disease activity.

Clinical Features and Associated Factors of Abdominal Pain in Systemic Lupus Erythematosus

To evaluate the clinical characteristics of systemic lupus erythematosus (SLE)-induced abdominal pain in a cohort in South China and identify the risk factors for SLE-induced abdominal pain. This is a retrospective cohort study of SLE patients with complaint of abdominal pain admitted to the first affiliated university hospital of Sun Yat-sen University between 2002 and 2011. Demographic information, clinical features, laboratory findings, SLE Disease Activity Index, and imaging characteristics were documented. Of the 3823 SLE patients reviewed, 213 patients complained of abdominal pain and 132 cases were considered SLE-induced. The most common causes were lupus mesenteric vasculitis (LMV; 73.5%, 97/132) and lupus pancreatitis (LP; 17.4%, 23/132). Other causes included appendicitis, acute gastroenteritis, and peritonitis. Univariate and multivariate logistic regression analysis indicated the European Consensus Lupus Activity Measurement (ECLAM) score was significantly associated with lupus-induced abdominal pain (OR = 1.858, 95% CI: 1.441-2.394, p < 0.001), LMV (OR = 1.713, 95% CI: 1.308-2.244, p < 0.001), and LP (OR = 2.153, 95% CI: 1.282, 3.617, p = 0.004). The serum D-dimer level (OR = 1.004, 95% CI: 1.002-1.005, p < 0.001) was a strongly associated factor for lupus-induced abdominal pain. Moderate and large amounts of ascetic fluid was significantly associated with lupus-induced abdominal pain and LMV. Elevated liver enzymes was a risk factor for LP (OR = 34.605, 95% CI: 3.591-333.472, p = 0.002). LMV and LP were the leading causes of SLE-induced abdominal pain. The serum D-dimer was a strongly associated factor for lupus-induced abdominal pain. ECLAM score was a reliable index in assessment of SLE-associated abdominal pain. Elevated liver enzymes, and moderate or large amounts of ascites, were positively associated with lupus-induced abdominal pain.
