Purpose. We analyzed the prevalence, clinical correlation, and the functional significance of ALA in patients with systemic lupus erythematosus (SLE).Methods. ALA IgG was detected by indirect immunofluorescence in the serum of 130 SLE patients, 75 patients with various rheumatic diseases, and 45 healthy controls (HC).Results. The sensitivity and specificity of ALA IgG in SLE were 42.3% and 96.7%, respectively. ALA was observed in 55.6% (50/90) of patients with lymphopenia, which was significantly higher than in patients with normal lymphocytes (5/40, 12.5%;P<0.001). Patients with active SLE showed higher ALA positivity (60.9%) than those with inactive disease (24.2%;χ2= 17.925;P<0.001). ALA correlated significantly with hypocomplementemia, anti-dsDNA antibodies, and higher SLEDAI scores. The incidences of ALA in SLE patients who were seronegative for anti-dsDNA, anti-Sm, or both antibodies were 32.9% (26/79), 41.0% (43/105), and 32.4% (22/68), respectively. The ALA-positive group also had higher incidences of neuropsychiatric SLE (NPSLE) and lupus nephritis (LN). In multivariate analyses, ALA was independently associated with lymphopenia, higher SLEDAI scores, and increased risk for LN. ALA titers significantly decreased as clinical disease was ameliorated following treatment.Conclusions. ALA occurred more frequently in patients with active SLE and was independently associated with lymphopenia, disease activity, and LN.

Introduction We aimed to investigate risk factors for fatigue in patients with systemic lupus erythematosus (SLE) and neuropsychiatric symptoms in order to identify potential interventional strategies. Methods Patients visiting the neuropsychiatric SLE (NPSLE) clinic of the Leiden University Medical Center between 2007–2019 were included. In a multidisciplinary consensus meeting, SLE patients were classified as having neuropsychiatric symptoms of inflammatory origin (inflammatory phenotype) or other origin (non-inflammatory phenotype). Fatigue was assessed with the SF-36 vitality domain (VT) since 2007 and the multidimensional fatigue inventory (MFI) and visual analogue scale (VAS) since 2011. Patients with a score on the SF-36 VT ≥1 standard deviation (SD) away from the mean of age-related controls of the general population were classified as fatigued; patients ≥2 SD away were classified as extremely fatigued. Disease activity was measured using the SLE disease activity index-2000. The influence of the presence of an inflammatory phenotype, disease activity and symptoms of depression and anxiety as measured by the hospital anxiety and depression scale (HADS) was analyzed using multiple regression analyses corrected for age, sex and education. Results 348 out of 371 eligible patients filled in questionnaires and were included in this study . The majority was female (87%) and the mean age was 43 ± 14 years. 72 patients (21%) had neuropsychiatric symptoms of an inflammatory origin. Fatigue was present in 78% of all patients and extreme fatigue was present in 50% of patients with an inflammatory phenotype vs 46% in the non-inflammatory phenotype. Fatigue was similar in patients with an inflammatory phenotype compared to patients with a non-inflammatory phenotype on the SF-36 VT (β: 0.8 (95% CI −4.8; 6.1) and there was less fatigue in patients with an inflammatory phenotype on the MFI and VAS (β: −3.7 (95% CI: −6.9; −0.5) and β: −1.0 (95% CI −1.6; −0.3)). There was no association between disease activity and fatigue, but symptoms of anxiety and depression (HADS) associated strongly with all fatigue measurements. Conclusion This study suggests that intervention strategies to target fatigue in (NP)SLE patients may need to focus on symptoms of anxiety and depression rather than immunosuppressive treatment.

Background Epidemiological studies in systemic lupus erythematosus have been reported in the literature in many countries and ethnic groups. Although systemic lupus erythematosus in Jamaica has been described in the past, there has not been a detailed evaluation of systemic lupus erythematosus patients in urban Jamaica, a largely Afro-Caribbean population. The goal of this study was to describe the clinical features, particularly disease activity, damage index and immunological features, of 150 systemic lupus erythematosus subjects. Methods 150 adult patients (≥18 years) followed in rheumatology clinic at a tertiary rheumatology hospital centre (one of two of the major public referral centres in Jamaica) and the private rheumatology offices in urban Jamaica who fulfilled Systemic Lupus International Collaborating Clinics (SLICC) criteria were included. Data were collected by detailed clinical interview and examination and laboratory investigations. Hence demographics, SLICC criteria, immunological profile, systemic lupus erythematosus disease activity index 2000 (SLEDAI-2K) and SLICC/American College of Rheumatology (ACR) damage index (SDI) were documented. Results Of the 150 patients, 145 (96.7%) were female and five (3.3%) were male. The mean age at systemic lupus erythematosus onset was 33.2 ± 10.9. Mean disease duration was 11.3 ± 8.6 years. The most prevalent clinical SLICC criteria were musculoskeletal, with 141 (94%) of subjects experiencing arthralgia/arthritis, followed by mucocutaneous manifestations of alopecia 103 (68.7%) and malar rash 46 (30.7%), discoid rash 45 (30%) and photosensitivity 40 (26.7%). Lupus nephritis (biopsy proven) occurred in 42 (28%) subjects and 25 (16.7%) met SLICC diagnostic criteria with only positive antinuclear antibodies/dsDNA antibodies and lupus nephritis on renal biopsy. The most common laboratory SLICC criteria were positive antinuclear antibodies 136 (90.7%) followed by anti-dsDNA antibodies 95 (63.3%) and low complement (C3) levels 38 (25.3%). Twenty-seven (18%) met SLICC diagnostic criteria with only positive antinuclear antibodies/anti-dsDNA antibodies and lupus nephritis on renal biopsy. Mean SLEDAI score was 6.9 ± 5.1 with a range of 0–32. Organ damage occurred in 129 (86%) patients; mean SDI was 2.4 ± 1.8, with a range of 0–9. Conclusion These results are similar to the clinical manifestations reported in other Afro-Caribbean populations; however, distinct differences exist with respect to organ involvement and damage, particularly with respect to renal involvement, which appears to be reduced in our participants.

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.

Abstract Background involvement of central and peripheral nervous systems are well-documented in SLE but literature on prevalence and pattern of autonomic neuropathy are few. Women with SLE have been found to have 5-8 fold increased risk of coronary heart disease. Autonomic dysfunction in the presence of structural cardiovascular disease is associated with adverse prognosis. Aim of the Work the purpose of this study is to evaluate the cardiovascular autonomic function in patients with Systemic lupus erythematosus, and to correlate it with SLE clinical features. Patients and Methods we conducted our study on one-hundred Egyptian SLE patients diagnosed according to SLICC classification criteria for SLE recruited from rheumatology outpatient clinic and inpatient department at Ain Shams University Hospitals. All the studied patients were subjected to history taking, clinical examination, and laboratory and radiological investigations related to SLE diagnosis and activity. SLE disease activity was assessed by SLE disease activity index-2000 (SLEDAI-2K).Tilt table test was used to assess for presence of cardiovascular autonomic neuropathy. Results we found that fifty (50%) of our SLE patients had symptoms suggestive for autonomic dysfunction, including orthostatic hypotension, palpitation and or Raynaud’s phenomenon. Regarding the result of tilt table test, sixty eight (68%) of the studied SLE patients were found to have positive tilt table responses. By doing the uni-variate analysis for predictors of SLE patients with positive tilt table test, we found that vasculitis, proteinuria, DNA, low TLC and complement levels, high SLEDAI, ESR and urinary P/C all were predictors for positivity of tilt table testing. Conclusion The prevalence of autonomic dysfunction was high among SLE patients.

Abstract Concentrations of neopterin were measured in urine specimens from 35 patients with active and eight with inactive systemic lupus erythematosus (SLE). Compared with those of apparently healthy controls, neopterin concentrations were higher in patients with active disease (P less than 0.001) and with inactive disease (P less than 0.01), those in patients with active disease being significantly higher than those in patients with inactive disease (P less than 0.001). The correlation between the neopterin concentration and evidence of disease activity was good. All of the patients with clinically active SLE had increased neopterin, but for only 37.5% (three of eight) did the neopterin concentration exceed the upper normal limit during clinical remission. The increase in neopterin concentration did not correlate with clinical courses or severity of renal function. Moreover, serial determinations of neopterin in active SLE patients showed a rapid decrease of initially high concentration, paralleling a decline of clinical activity after initiation of medical therapy. Thus, urinary neopterin may be a useful marker for monitoring disease activity in SLE patients.

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.

Objective.Type I interferons (IFN), especially IFN-α, have been proposed to underlie the pathogenesis of systemic lupus erythematosus (SLE). Members of the IFN regulatory factor (IRF) family, which regulate IFN expression, have been implicated as risk factors for SLE. Our aims were to investigate the expression of IRF7 and its correlation with disease activity and to explore the association in Taiwanese patients between 2 genetic single-nucleotide polymorphisms (SNP) of IRF7 and SLE.Methods.IRF7 messenger RNA (mRNA) levels were measured in peripheral blood mononuclear cells by real-time reverse transcription polymerase chain reaction in 51 adult patients with SLE and 65 age-matched and sex-matched controls. Their serum IFN-α levels were determined by ELISA and the clinical manifestations were recorded at the same time. Two IRF7 SNP, rs1061501 and rs1061502, were examined by genotyping across 92 patients with SLE and 92 age and sex-matched healthy control subjects.Results.Compared with controls, the expression of IRF7 mRNA was significantly increased in patients with SLE and was positively correlated with both the serum level of IFN-α and lupus disease activity. The distribution of SNP rs1061501 by genotype (CC, CT, and TT) and by allele (C, T) was significantly different between the SLE and the control group (p = 0.028 for genotype and p = 0.009 for allele). There were no significant differences for SNP rs1061502.Conclusion.The results suggest that dysregulation of IRF7 might mediate an excessive production of IFN-α, which then exerts a crucial effect on the pathogenesis of human SLE. The IRF7 SNP rs1061501 TT genotype and T allele are enriched in Taiwanese patients with SLE and thus would seem to be associated with an increased risk of developing SLE.

Background Cathelicidin (LL-37), an endogenous antimicrobial peptide, has recently been involved in the pathogenesis of autoimmune diseases. To assess whether LL-37 reflects disease activity, we measured serum levels of it in systemic lupus erythematosus (SLE) patients with active and inactive disease compared to healthy controls. LL-37 was also compared between new and old cases. Moreover, the correlation of LL-37 and pro-oxidant, antioxidant balance (PAB) was measured. Methods The study population consisted of 50 SLE patients and 28 healthy controls. Of those, 39 patients had active and 11 patients had inactive disease. Serum levels of LL-37 were measured by ELISA and PAB values by a special method. Results There was no difference in levels of LL-37 between patients and healthy controls (50.9 ± 20.8 vs. 67.7 ± 43.3 ng/ml, P = 0.31). LL-37 did not correlate with SLEDAI and its items in total patients. LL-37 had a positive correlation with SLEDAI in active patients ( P = 0.01, r = 0.4). In active patients (78% of patients), multivariate regression analysis showed significant negative correlation between LL-37 and C3 ( P = 0.01, standardized beta –0.50). No difference was found in levels of PAB between patients and controls (90.4 ± 34.1 vs. 86.9 ± 25.6 HK, P = 0.4).There was no difference in the levels of PAB between patients with active and inactive disease (93.2 ± 34.1 vs. 80.2 ± 33.7 HK, P = 0.27). No correlation was found between levels of PAB and SLEDAI items and total score. However, a positive correlation between the levels of LL-37 and PAB in SLE patients was found ( r = 0.3, P < 0.01). Conclusion Based on this study, serum LL-37 and PAB did not increase in lupus compared with healthy individuals. LL-37 serum values rose in parallel with SLEDAI in active disease. Positive correlation between serum PAB and LL-37 could be a great achievement of this study that may suggest the role of antioxidants in controlling NETosis.

ObjectiveTo determine the risk of thrombosis in patients with systemic lupus erythematosus (SLE) and other autoimmune diseases of recent onset.MethodsA retrospective cohort of 482 patients, mean age 28.3 years, with SLE or other autoimmune diseases was analyzed. Followup started at diagnosis or first appointment within 12 months since diagnosis until the development of thrombosis, end of study, loss to followup, or death. Thromboses were diagnosed upon clinical manifestations and confirmed by appropriate studies. Clinical variables were retrieved from the medical records, and SLE activity was assessed from the medical notes at onset of thrombosis, or at a dummy date for thrombosis, using the SLE Disease Activity Index-2K.ResultsDuring 2936 patient-years of followup, thromboses occurred in 49 patients (20.3%) with SLE and 6 patients (2.5%) with other autoimmune diseases. The incidence rate of thrombosis was 36.3 and 3.8 per 1000 patient-years in SLE and in other autoimmune diseases, respectively; relative risk 9.6 (95% CI 4.1–27.4, p < 0.0001). Throughout the disease course, the risk of thrombosis remained high in the SLE group, while in patients with other autoimmune diseases this risk was lower. The incidence of venous and arterial thrombosis was similar among SLE patients and patients with other autoimmune diseases. SLE and venous insufficiency were associated with thromboses in the total study population, and with venous insufficiency, vasculitis, and disease activity in the SLE group.ConclusionPatients with autoimmune diseases, particularly SLE, are at an increased risk of thrombosis. In patients with SLE, the risk remains elevated throughout the course of the disease.
