Trend of Survival of a Cohort of Chinese Patients With Systemic Lupus Erythematosus Over 25 Years.

Objectives: To revisit the trend of survival of systemic lupus erythematosus in a cohort of Chinese patients over 25 years.Methods: Patients who fulfilled the 1997 ACR criteria for SLE and were followed in our hospital since 1995 were included. Patients were stratified into two groups according to the year of diagnosis: (1) 1995–2004 and (2) 2005–2018. Survival of patients was studied by Kaplan–Meier analysis. Organ damage as assessed by the Systemic Lupus International Collaborating Clinics (SLICC) damage index (SDI) and causes of death in the first 10 years of SLE onset was compared between the two groups. Cox regression was used to study factors associated with survival.Results: A total of 1,098 SLE patients were registered in our database. After excluding 157 patients diagnosed outside the time period of 1995–2018, 941 patients were studied (92% women). All were ethnic Chinese. The mean age of SLE onset was 35.1 ± 14.4 years, and the mean duration of observation was 13.1 ± 6.6 years. Seventy-seven (8.2%) patients were lost to follow-up. Groups 1 and 2 consisted of 364 and 577 patients, respectively. The mean SDI score at 10 years of disease onset was significantly higher in group 1 than group 2 patients (1.01 ± 1.43 vs. 0.57 ± 0.94; p < 0.01), particularly in the neuropsychiatric, musculoskeletal, and gonadal domains. Within 10 years of SLE onset, 32 (8.8%) patients in group 1 and 25 (4.3%) patients in group 2 died (p = 0.005). The 5- and 10-year cumulative survival rates were 93.6 and 91.0% in group 1 and 96.5 and 94.2% in group 2 patients, respectively (log-rank test p = 0.048). Infection accounted for more than half of the deaths in both groups. More group 1 than group 2 patients died of vascular events, but the difference was not statistically significant. Cox regression showed that the age of SLE onset and damage score accrued at 10 years, but not the time period in which SLE was diagnosed, were significantly associated with mortality.Conclusions: The improvement in survival of our SLE patients is probably related to the accrual of less organ damage in the past 15 years.

SAT0162 WITHDRAWAL OF LOW-DOSE STEROIDS IN SYSTEMIC LUPUS ERYTHEMATOSUS IN REMISSION: PREDICTORS OF FLARES AND DIFFERENCE IN OUTCOMES IN SEROLOGICALLY ACTIVE CLINICALLY QUIESCENT PATIENTS

Background:According to the recent recommendations for Systemic Lupus Erythematosus (SLE), a progressive tapering until withdrawal of glucocorticoids (GC) is considered one of the main goals of SLE management (1). However, which patient may be a candidate for safe GC withdrawal has not been determined yet and a proportion of patients are kept on long-term low-dose prednisone despite clinical remission.Objectives:to evaluate the rate of low-dose GC withdrawal in SLE patients in remission and to identify predictors of flares.Methods:Eligible patients were SLE patients according to the ACR criteria (2) who were in prolonged clinical remission defined by a cSLEDAI=0 for at least 2 years and on a stable SLE treatment (immunosuppressive drugs and/or hydroxychloroquine (HCQ) and daily 5 mg prednisone). A SACQ period was defined as at least 1-year period with persistent serologic activity without clinical manifestations. Flares were defined by SELENA-SLEDAI Flare Index (3). Damage was assessed by SLICC damage index (SDI). Data were compared by the unpaired student’s t test or chi-squared test as appropriate. Predictors of flares after GC withdrawal were analyzed by Cox regression.Results:Out of 246 SLE patients registered in the Naples Lupus Clinic database, 132 eligible patients were identified. Among them, we selected 57 (43%) patients in whom a GC withdrawal was attempted. 75 (57%) patients were in the prednisone maintenance group.There were no significant differences between the two treatment groups (table 1). The proportion of patients experiencing a flare was not significantly lower in the maintenance group than in the withdrawal group (15/75 vs 16/57; p=0.28). Moreover, the proportion of patients who had an increase in the SDI at the end of follow up was similar between the two groups (14/75 vs 8/57; p=0.48). However, among the withdrawal group, the rate of flares was significantly higher in SACQ patients (10/22 vs 6/35; p=0.02), while the majority of serologically inactive patients (82%) successfully stopped GCs without subsequent flares. At Cox regression analysis (Table 2), duration of HCQ therapy and &gt;4 year remission at withdrawal were protective factors, while a SACQ disease and history of lupus nephritis (LN) increased the risk of disease flare.Table 1.Baseline characteristics of 132 patients at study entryCharacteristicsWithdrawal group (n=57)Maintenance group (n=75)p-valueFemale, no.

In SACQ patients, maintenance of 5mg prednisone is superior to its withdrawal in order to prevent flares. Long-term HCQ therapy and prolonged remission can significantly reduce the risk of disease relapse after GC withdrawal.

FRI0583 VALIDATION OF THE MODIFIED FATIGUE IMPACT SCALE IN DANISH PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS

Background:Patients with systemic lupus erythematosus (SLE) experience significant fatigue, a debilitating symptom associated with reduced quality of life. A simple, reliable multidimensional method for assessing fatigue has not yet been validated for Danish patients with SLE.Objectives:The primary objective was to study the internal consistency, test-retest reliability, and construct validity (convergent and discriminant validity) of the multidimensional Modified Fatigue Impact Scale (MFIS) in patients with SLE. The secondary objective was to investigate the contribution of disease activity and organ damage to fatigue.Methods:Data from the ”Bio and Genome Bank Study in Centre for SLE and Vasculitis” obtained through routine visits were used. Fatigue was assessed using the MFIS and Short Form 36 (SF36). Internal consistency of the MFIS was assessed with Cronbach’s alpha (α). Test-retest reliability was evaluated using the intraclass correlation coefficient (ICC). Construct validity was studied using Spearman’s rank correlation coefficient (rs) and Principal Component Analysis (PCA) between MFIS and SF36 vitality (VT-SF36) and mental health (MH-SF36) subscales. Association between MFIS and disease activity and organ damage was estimated with Spearman’s rank correlation coefficient.Results:The study included 30 patients with SLE. Internal consistency of the MFIS was excellent with Cronbach’s α = 0.97 for the complete scale. Excellent test-retest reliability was found with ICC = 0.95 (95% confidence interval: 0.88-0.98, p &lt; 0.05). Construct validity was confirmed by Spearman’s correlation (VT-SF36: rs= −0.73, p &lt; 0.001 (Fig. 1). MH-SF36: rs= −0.74, p &lt; 0.001 (Fig. 2)) and PCA with explained variance from the first two principal components (PC) (VT-SF36: PC1 = 60.2%, PC2 = 8.5%. MH-SF36: PC1 = 58.5%, PC2 = 7.4%). No significant correlation was found between the MFIS and SLEDAI (rs= 0.04, p = 0.84) or SLICC Damage Index (rs= 0.32, p = 0.08).Figure 1.Scatter plot of the Modified Fatigue Impact Scale (MFIS) and the Short Form 36 vitality (VT-SF36) subscale.Figure 2.Scatter plot of the Modified Fatigue Impact Scale (MFIS) and the Short Form 36 mental health (MH-SF36) subscale.Conclusion:The present study found the multidimensional assessment of fatigue with MFIS to be a reliable and valid instrument in SLE. The MFIS might provide more detailed information about fatigue in future studies. In agreement with some previous studies we found no association between fatigue and SLEDAI or SLICC which raises questions about the cause of this symptom. Further and larger studies are needed to investigate if any association between fatigue and disease components exist.Disclosure of Interests:None declared

Clinical and laboratory characteristics in juvenile-onset systemic lupus erythematosus across age groups.

BackgroundSystemic lupus erythematous (SLE) is a systemic autoimmune/inflammatory condition. Approximately 15–20% of patients develop symptoms before their 18th birthday and are diagnosed with juvenile-onset SLE (JSLE). Gender distribution, clinical presentation, disease courses and outcomes vary significantly between JSLE patients and individuals with adult-onset SLE. This study aimed to identify age-specific clinical and/or serological patterns in JSLE patients enrolled to the UK JSLE Cohort Study.MethodsPatient records were accessed and grouped based on age at disease-onset: pre-pubertal (≤7 years), peri-pubertal (8–13 years) and adolescent (14–18 years). The presence of American College of Rheumatology (ACR) classification criteria, laboratory results, disease activity [British Isles Lupus Assessment Group (BILAG) and Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2 K) scores] and damage [Systemic Lupus International Collaborating Clinics (SLICC) damage index] were evaluated at diagnosis and last follow up.ResultsA total of 418 JSLE patients were included in this study: 43 (10.3%) with pre-pubertal disease onset; 240 (57.4%) with peri-pubertal onset and 135 (32.3%) were diagnosed during adolescence. At diagnosis, adolescent JSLE patients presented with a higher number of ACR criteria when compared with pre-pubertal and peri-pubertal patients [pBILAG2004 scores: 9(4–20] vs. 7(3–13] vs. 7(3–14], respectively, p = 0.015] with increased activity in the following BILAG domains: mucocutaneous (p = 0.025), musculoskeletal (p = 0.029), renal (p = 0.027) and cardiorespiratory (p = 0.001). Furthermore, adolescent JSLE patients were more frequently ANA-positive (p = 0.034) and exhibited higher anti-dsDNA titres (p = 0.001). Pre-pubertal individuals less frequently presented with leukopenia (p = 0.002), thrombocytopenia (p = 0.004) or low complement (p = 0.002) when compared with other age groups. No differences were identified in disease activity (pBILAG2004 score), damage (SLICC damage index) and the number of ACR criteria fulfilled at last follow up.ConclusionsDisease presentations and laboratory findings vary significantly between age groups within a national cohort of JSLE patients. Patients diagnosed during adolescence exhibit greater disease activity and “classic” autoantibody, immune cell and complement patterns when compared with younger patients. This supports the hypothesis that pathomechanisms may vary between patient age groups.

Obesity increases the incidence of new-onset lupus nephritis and organ damage during follow-up in patients with systemic lupus erythematosus.

Objective This study explored the effects of obesity on clinical manifestations, disease activity and organ damage in Korean patients with systemic lupus erythematosus (SLE). Methods We assessed 393 SLE patients annually for three consecutive years based on demographic information, clinical manifestations, laboratory findings and Physician Global Assessment, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2000 and Systemic Lupus International Collaborating Clinics (SLICC) damage index (SDI) scores. Patients were grouped by body mass index (BMI): normal weight, BMI &lt;23 kg/m2; overweight, 23 kg/m2 ≤BMI &lt;25 kg/m2; obese, BMI ≥25 kg/m2. The impact of obesity on clinical outcomes was assessed using univariate and multivariate analyses. Results Of the 393 patients, 59 (15.0%) were obese at enrollment. They had more comorbidities compared with non-obese patients, including diabetes, hypertension, hyperlipidemia and pulmonary hypertension. Nephritis at enrollment and newly developed nephritis during follow-up were more common ( p = 0.002 and p = 0.002, respectively) and Physician Global Assessment and SDI scores were higher in these patients for three consecutive years ( p = 0.017 and p = 0.039, respectively). Multivariate analysis revealed that obesity was significantly associated with development of nephritis during follow-up (odds ratio = 26.636; 95% confidence interval, 11.370–62.399; p &lt; 0.001) and cumulative organ damage (odds ratio = 4.096; 95% confidence interval, 2.125–7.894, p &lt; 0.001). Conclusions The incidences of newly developed nephritis and cumulative organ damage were higher in obese SLE patients than in non-obese SLE patients.

Association of Oxidative Stress with Disease Activity and Damage in Systemic Lupus Erythematosus: A Cross Sectional Study from a Tertiary Care Centre in Southern India.

To study oxidative stress in systemic lupus erythematosus (SLE) by estimating serum oxidised LDL (OxLDL), 8-hydroxy-2'-deoxyguanosine (8-OHdG), malondialdehyde (MDA), and total anti-oxidant status and to correlate with SLE disease activity and disease damage. Eighty SLE patients satisfying the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) 2012 criteria and 80 healthy controls were studied. Exclusion criteria were infections, renal insufficiency, other connective tissue diseases, drug-induced lupus, smoking, alcohol consumption. Disease activity was measured by SLE disease activity index-2K (SLEDAI), disease damage was quantified by SLICC-Damage Index (SDI). Sera was tested for OxLDL, 8-OHdG, and total antioxidant status (TAS) by double-antibody sandwich ELISA; MDA measured by Colorimetric assay. Oxidative stress markers were compared between group1- controls, group 2-mildly active SLE (SLEDAI ≤ 5), group 3- moderate to highly active SLE (SLEDAI ≥ 6). SLE patients had significantly higher MDA, 8-OHdG and lower TAS when compared to healthy controls, while OxLDL was similar in the three groups. MDA, 8-OHdG were significantly higher, TAS lower in group 3 compared to group 2. MDA had positive correlation with SLEDAI, TAS negatively correlated with SLEDAI. SLE with neuropsychiatric manifestations, vasculitis, anti-sdDNA antibodies had higher MDA, MDA/TAS ratio. SLE patients with thrombocytopenia, and vasculitis had higher OxLDL. Only OxLDL was significantly higher in those patients who have SDI > 1. SLE patients have increased oxidative stress measured by increases in MDA, 8-OHdG, and lower total antioxidant status that was associated with disease activity and some disease manifestations. However only OxLDL was associated with damage.

The additive effects of hydroxychloroquine to maintenance therapy with standard of care in patients with systemic lupus erythematosus.

In this retrospective study, the effect of hydroxychloroquine (HCQ) added to maintenance therapy according to the standard of care (SoC) was evaluated for 1year in 101 patients with systemic lupus erythematosus (SLE). The primary endpoint was the SLE Disease Activity Index (SLEDAI). The secondary endpoints were the British Isles Lupus Assessment Group index, serum complement activity (CH50) levels, anti-double-stranded DNA (dsDNA) antibody titer, concomitant corticosteroid (CS) dose, and Systemic Lupus International Collaborating Clinics (SLICC) damage index. These variables were compared between the SoC+HCQ (n=42) and SoC (n=59) groups. The SLEDAI improved from 2 (0, 6) to 0 (0, 4) in the SoC+HCQ group (P = .038) but significantly deteriorated from 1 (0, 4) to 2 (0, 8) in the SoC group (P = .033). CH50, anti-dsDNA antibody titer, concomitant CS dose, and SLICC damage index did not significantly change. The increase in the SLEDAI and concomitant CS dose after 1year were all significantly greater in the SoC group, and the proportion of patients with SLEDAI flare was significantly lower in the SoC+HCQ group (SoC+HCQ: 4.76% vs SoC: 25.4%, P=.006). Univariate logistic regression analyses identified HCQ as a predictive factor for no SLEDAI flare (P=.003, odds ratio 6.81, 95% confidence interval 1.77-45.00). The use of HCQ effectively improved SLEDAI scores and was a predictive factor for the prevention of SLEDAI flare. Therefore, HCQ may be considered a potential mainstay of maintenance therapy.

Assessment of severity and pattern of irreversible organ damage in patients with systemic lupus erythematosus and systemic scleroderma

The article is devoted to the study of the degree and pattern of irreversible changes in the organs and systems of the body using the SLICC damage index in patients with systemic lupus erythematosus (SLE) and systemic scleroderma (SSc) with a disease duration of more than 5 years. Data were obtained from a high incidence of adverse changes in patients with SLE and SSc. In patients with SLE, adverse changes in the cardiovascular system, central nervous system in the form of acute cerebral circulation disorders and seizures, as well as venous thrombosis, damage to the organ of vision in the form of cataracts, proteinuria (more than 3.5 g per day) and alopecia prevailed. Patients with SSc more often developed lesions of the respiratory organs in the form of pulmonary fibrosis and pulmonary hypertension, the musculoskeletal system, skin and neuropathy of the cranial nerves and peripheral nerves.

Systemic lupus erythematosus: genetic variants in Xq28 region.

ObjectivesMethyl-CpG-binding protein 2 (MECP2) and interleukin-1 receptor-associated kinase (IRAK1) are encoded by adjacent X-linked genes and recognized for their role in regulation of inflammation. The present case control study was conducted to detect the genetic association between MECP2 (rs1734791) and IRAK1 (rs1059703) single nucleotide polymorphisms (SNPs) and susceptibility to systemic lupus erythematosus (SLE), and the possible association of these SNPs and severity of SLE.Material and methodsFifty patients with SLE and 100 healthy controls were included in this study. Systemic Lupus International Collaborating Clinics (SLICC) criteria were used to classify SLE patients and the activity of the disease was assessed by SLEDAI score. Disease severity was assessed by the SLICC damage index (SLICC DI). Genetic association of both SNPs with SLE was assessed by Taq Man allelic discrimination technique.ResultsAnalyses of MECP2 (rs1734791) SNP genotypes revealed that homozygous TT genotype was significantly higher in the control group than SLE patients (p < 0.001, odds ratio [OR] = 0.120). Frequency of allele (A) was significantly higher in SLE patients, (p < 0.001, OR = 0.334). SLE patients had significantly higher frequency of the homozygous AA and heterozygous AG genotype of IRAK1 (rs1059703) SNP in comparison to healthy controls (p = 0.0029, OR = 4.17 and 6.30 respectively). T+G and T+A of rs1734791 and rs1059703 SNPs are protective haplotypes (OR = 0.47 and 0.3, p = 0.0046 and < 0.012 respectively). No significant association between either SNP and disease activity or severity was found.ConclusionsThere is a possible genetic association between both rs1734791 and rs1059703 SNPs and susceptibility to SLE, while no significant association between either SNP and disease activity or severity was detected.

P4450Atherosclerosis in women with systemic lupus erythematosus with and without nephritis

Abstract Background Nephritis in systemic lupus erythematosus (SLE) is a factor contributing to early development of atherosclerosis (AS). Objectives The aim of the study is to determine differences in cardiovascular risk factors and AS in SLE pts with and without lupus nephritis (LN). Methods The study included 162 females, age 35 [26–43] years (median [interquartile range 25–75%])) with SLE (ACR,1997). We divided SLE pts on two groups, comparable in age: the 1st group is the pts with LN (n=84, 52%), the 2nd - without LN (n=78, 48%). We considered traditional factors of cardiovascular disease (CVD): (smoking, family history of CVD, blood pressure, cholesterol (total, HDL, LDL) and triglyceride (TG) levels, body mass index, diabetes mellitus) and SLE-related factors (age at onset, duration, clinical features, SLE Disease Activity Index (SLEDAI-2K) and the Systemic Lupus International Collaborating Clinics damage index (SLICC/DI), treatment with steroids); intima-media thickness (IMT) and the 10-year risk for coronary events. Carotid intima-media wall thickness of common carotid arteries was measured by high resolution B-mode ultrasound. The 10-year risk for coronary events was estimated by the Framingham risk equation. Results Median SLE duration was 8,0 [2,3–17,0] years, SLEDAI 2K – 8 [3–16], SLICC/DI score – 2 [0–3], duration of prednisone treatment – 72 [26–141] months. SLE pts from the 1st group had higher prevalence of hypertension (61% vs 36%, p&lt;0,01), systolic blood pressure (130 [110–150] vs 120 [110–130]mm Hg, p&lt;0,01), diastolic blood pressure (80 [70–95] vs 70 [70–80] mm Hg, p&lt;0,05), TG concentration (136 [98–184] vs 100 [61–162] mg/dl, p&lt;0,01), Framingham Risk Score (5 [1–30] vs 1 [1–27]%, p&lt;0,05), SLEDAI-2K (12 [5–19] vs 4 [2–10], p&lt;0,ehz745.08501), SLICC/DI score (2 [0–4] vs 0 [0–2], p&lt;0,01), prednisone therapy duration (95 [26–192] vs 44 [14–98] months, p&lt;0,05), prednisone cumulative dose (34,4 [13,6–82,5] vs 15,7 [6,2–35,2] g, p&lt;0,001), mean IMT (0,73 [0,65–0,83] vs 0,67 [0,61–0,75] mm, p&lt;0,01), than the pts from the 2nd group. There is no difference in CVD frequency in these groups (17% vs 8%, p=0,084). Conclusions SLE patients with and without LN had no difference in frequency of clinical manifestations of AS (CVD), but had a greater value of mean IMT, Framingham Risk Score and a higher incidence of both traditional (hypertension, TG concentration) and SLE-related (disease activity, prednisone therapy) risk factors for AS.

IMPACT OF THERAPY ON HEALTH-RELATED QUALITY OF LIFE IN PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS (ACCORDING TO THE RENAISSANCE REGISTER)

Objective: to assess changes in health-related quality of life (HRQoL) in patients with systemic lupus erythematosus (SLE) during performed therapy.Subjects and methods. The investigation included 128 patients with reliable SLE who fulfilled the 2012 SLICC criteria. Sixty-eight patients received standard therapy; 60 used biological agents (BA). During the first visit and at 12 months, all the patients were assessed for disease activity using by SLEDAI-2K and for organ damage employing the SLICC damage index (DI). HRQoL was assessed by the LupusQoL questionnaire that was filled out by the patients independently.Results and discussion. At Visit 1, the disease activity index averaged 8.0±7.3 in the standard therapy group and 15.4±7.6 in the BA group (p≤0.001); DI was 1.2±0.9 and 1.8±1.8, respectively (p=0.008). BA-treated patients had significantly lower HRQoL scores on all questionnaire scales, except «dependence on others» and «emotional health» ones Both the standard therapy and BA groups showed significantly lower disease activity during Visit 2 at 12 months. HRQoL assessment revealed significant improvements in the scales «pain», «planning», «intimate relationships», «emotional health», «body image», and «fatigue» in the BA group. The standard therapy group had a statistically significant improvement in the scale «dependence on others». All the other scales of the questionnaire displayed a positive change in HRQoL; however, it did not reach statistical significance.

Neutrophil/lymphocyte and platelet/lymphocyte ratios are useful predictors comparable to serum IL6 for disease activity and damage in naive and relapsing patients with lupus nephritis

Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have become recently useful as predictive and prognostic tools in patients with various medical conditions. Aim of the workTo evaluate NLR and PLR in systemic lupus erythematosus (SLE) and their relation to disease clinical characteristics, nephritis, disease activity and damage. Patients and methodThe study involved 110 Egyptian SLE patients; 80 with lupus nephritis (naive and relapsing) and 30 without as well as 50 matched control. Patients were subjected to full clinical examination, SLE disease activity index (SLEDAI) scoring, and damage using Systemic Lupus International Collaborating Clinics Damage Index (SLICC-DI). Laboratory and immunology profiles included the complete blood count (CBC) with differential white blood cell counts and estimation of both NLR and PLR, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), protein/creatinine ratio, anti-nuclear antibody (ANA), anti-double stranded deoxyribonucleic acid (anti-dsDNA), serum complements and interleukin-6 (IL-6) levels. ResultBoth NLR and PLR were significantly higher in SLE patients (4.8 ± 1.4 and 281.7 ± 66.7 respectively) compared to controls (3.8 ± 2 and 138.2 ± 50.4). Both ratios were significantly elevated in patients with active lupus nephritis (at presentation or as a flare) and were comparable between naive and relapsing lupus nephritis patients. In lupus nephritis patients, NLR and PLR significantly correlated with proteinuria, ESR, hypocomplementemia, IL6, SLEDAI and SLICC-DI. The best NLR cut-off value to predict nephritis activity was 5.65, whereas the best PLR cut-off value was 316.5. ConclusionNLR and PLR appear to be potentially useful cheap parameters of activity, relapse and severity in SLE patients with nephritis.

Associations between resilience and sociodemographic factors and depressive symptoms in women with systemic lupus erythematosus

ObjectiveTo compare resilience in women with SLE and healthy women and determine whether sociodemographic factors and depressive symptoms were associated with resilience in patients with SLE. MethodsThis was a cross-sectional study. Participants were 123 women with SLE according to the ACR criteria and 132 age-matched healthy women (median = 45 (IQR = 34–54) years). Scales administered were: SLEDAI-2 K for disease activity, Graffar method, SLICC damage index, Center for Epidemiologic Studies Depression Scale, and the Spanish version of the Resilience Scale of Wagnild and Young. The statistical analysis was made using the Student t, Mann Whitney, Chi-square, and Spearman's Rho tests and multivariate analysis with a generalized linear model (GLM). Statistical significance was set as p < .05. ResultsThere were no differences in resilience scores between women with SLE and healthy women (median = 80, IQR = 75–87 vs. median = 80, IQR = 74–86.75, p = .38), although patients with SLE had higher self-efficacy scores (median = 47 IQR = 43–50 vs. median = 45, IQR = 42–48, p = .002) and depressive symptoms (median = 10, IQR = 5–18 vs. median = 8, IQR = 5–18, p = .01). The overall resilience score correlated with depressive symptoms (r = −0.537, p < .01). The GLM showed no association between sociodemographic factors and resilience in patients with SLE. ConclusionsResilience did not differ between women with SLE and healthy women. In patients with SLE, depressive symptoms may influence resilience and its domains, but sociodemographic factors do not. Public health significance statementThe results suggest that resilience was similar between females with systemic lupus erythematosus (SLE) and age-matched healthy women. Depressive symptoms correlated negatively with resilience in patients with SLE. Sociodemographic factors were not associated with resilience in patients with SLE.

Lymphopenia in systemic lupus erythematosus patients: Is it more than a laboratory finding?

Aim of the workTo investigate the relation between lymphopenia and clinical manifestations, laboratory findings, disease activity and damage index in systemic lupus erythematosus (SLE) patients. Patients and methods124 SLE patients were recruited from the Rheumatology Department in-patient and outpatient clinic, Faculty of medicine, Cairo University Hospitals. SLE disease activity index (SLEDAI) and the systemic lupus international collaborating clinics damage index (SLICC-DI) were assessed. Patients were divided into two groups according to presence or absence of lymphopenia (lymphocyte count ≤1500 cells/mm3), and were compared as regards different disease parameters. ResultsThe 124 patients were 113 females (91.1%) and 11 males (8.9%). Their mean age was 28.54 ± 8.25 years and median disease duration was 48 (24–105) months. 86 (69.4%) had renal involvement, complement C3 was consumed in 84 (67.7%) and C4 in 44 (35.5%). All were receiving steroids and a high dose was more frequent in those with lymphopenia (17 (29.8%) compared to those without (in 9 (13.4%). Lymphopenia was found in 57 (46%) patients. Lymphopenic patients had higher frequency of renal involvement (p = 0.002) (OR = 3.37, CI = 1.5–7.8), complement consumption (p = 0.03), 24 h urinary proteins (p = 0.034), higher steroid doses (p = 0.012) and cyclophosphamide administration (p = 0.03). SLEDAI was severe in 29.8% of lymphopenic patients (p = 0.16), and SLICC-DI median was 2 in both groups (p = 0.4). ConclusionLymphopenia is a common finding in SLE patients and was significantly associated with lupus nephritis, complement consumption, higher steroid doses and cyclophosphamide administration. Lymphopenia might be a promising marker for renal involvement in SLE.

Carotid artery atherosclerosis and ECG changes in patients with systemic lupus erythematosus: relation to disease activity and severity

AimThis study aimed to detect atherosclerotic changes in the carotid arteries of systemic lupus erythematous (SLE) patients as an indicator of cardiovascular risk factors and to correlate the findings with disease severity and activity parameters as well as to study specific ECG changes in these patients to elucidate possible associations between these variables.Patients and methodsThis study included 30 SLE patients who met the Systemic Lupus International Collaborating Clinics (SLICC) criteria (group I), 30 rheumatoid arthritis (RA) patients diagnosed according to the American College of Rheumatology/European league against rheumatism (EULAR) 2010 criteria (group II), and 30 apparently healthy volunteers age and sex matched to the SLE patients’ group (group III). All patients were subjected to full history taking, thorough clinical examination, assessment of disease activity using the Systemic Lupus Erythematous Disease Activity Index (2 K) score and assessment of damage by the SLICC/American College of Rheumatology Damage Index (SDI). Laboratory investigations included: complete blood count, erythrocyte sedimentation rate, lipid profile, immunological profile (antinuclear antibodies, anti-double-stranded DNA antibody, anticardiolipin antibody, and complements C3 and C4). The right common carotid artery was scanned by ultrasound and the average of carotid intima media thickness (CIMT) was calculated (mean of four readings) for all participants participating in the study. ECG was also done for all participants.ResultsThe mean CIMT was higher in RA patients (0.71±0.194 mm) with a nonsignificant difference compared with SLE patients (0.68±0.197 mm) and a high statistically significant difference (P<0.001) compared with healthy controls (0.34±0.09 mm). There was no statistically significant correlation of the mean CIMT (mm) with SLICC damage index (P=0.09) and disease activity score (P>0.05). Abnormal ECG findings were observed in 3/30 SLE patients (10%), 10/30 RA patients (33.3%), and one/30 healthy control (3.3%), with statistically significant difference (P<0.03) among groups. The presence or absence of abnormal ECG findings showed statistically insignificant differences regarding patients’ disease activity and mean CIMT.ConclusionAlthough ECG changes were present in 10% of our SLE patients, association of specific ECG changes could not be confirmed. A greater prevalence of increased CIMT was observed in SLE patients, emphasizing the important role of this disease in the development of premature atherosclerosis which did not correlate with disease activity or severity parameters.

Homocysteine levels are independently associated with damage accrual in systemic lupus erythematosus patients from a Latin-American cohort.

To determine the impact of homocysteine levels on damage accrual in systemic lupus erythematosus (SLE) patients. This longitudinal study was conducted in consecutive patients seen every 6months at our Rheumatology Department since 2012. Patients with available homocysteine levels and who had at least one subsequent visit were included. Univariable and multivariable Cox regression models were done to determine if homocysteine levels were predictive of damage accrual as per the SLICC Damage Index (SDI). The multivariable model was adjusted for pertinent variables (age at diagnosis, gender, socioeconomic status, disease duration, disease activity (SLEDAI), Framingham score, antimalarial and immunosuppressive drug use, average daily dose, and exposure time to prednisone (PDN)). One hundred forty-five patients were included; their mean (SD) age at diagnosis was 43.70 (12.09) years, 136 (93.8%) were female, and nearly all were Mestizo. At baseline, disease duration was 7.55 (6.73) years; patients were followed for 3.54 (1.27) years. The SLEDAI was 5.60 (4.34), and the SDI 0.97 (1.35). The average daily PDN dose was 7.30 (5.78) mg/day and the time of PDN exposure was 7.36 (6.73) years. Mean homocysteine levels were 10.07 (3.71) μmol/L. The highest tertile of homocysteine levels predicted new damage accrual in the univariable and multivariable models [HR 1.78 (95% CI, 1.042-3.039); p = 0.035 and HR 2.045 (95% CI, 1.077-3.883); p = 0.029, respectively]. Increased levels (> 15μmol/L) were found in 12 (8.3%) patients; 75 (51.7%) patients increased ≥ 1 SDI point. In SLE patients, homocysteine levels predicted damage accrual independently of other well-known risk factors for such occurrence.

The relationship between remission and health-related quality of life in a cohort of SLE patients.

To investigate the relationship between remission and health-related quality of life (HRQoL) in patients with SLE in a longitudinal observational cohort. HRQoL was measured at cohort visits using the physical and mental component score (PCS and MCS, respectively) of the Short Form 36 questionnaire. Definitions of Remission in SLE remission categories (no remission/remission on therapy/remission off therapy) were applied. Determinants of PCS and MCS were identified with simple linear regression analyses. Association between remission and HRQoL was assessed using generalized estimating equation models. Data from 154 patients with 2 years of follow-up were analysed. At baseline 60/154 (39.0%) patients were in either form of remission. Patients in remission had higher Short Form 36 scores in all subdomains compared with patients not in remission. PCS was positively associated with remission and employment, and negatively associated with SLICC damage index, ESR, medication, patient global assessment and BMI. MCS was positively associated with Caucasian ethnicity and negatively associated with patient global assessment. In generalized estimating equation analysis, a gradual and significant increase of PCS was observed from patients not in remission (mean PCS 36.0) to remission on therapy (41.8) to remission off therapy (44.8). No significant difference in MCS was found between remission states. we show a strong and persistent association between remission and PCS, but not MCS. These results support the relevance (construct validity) of the Definition of Remission in SLE remission definitions and the further development of a treat-to-target approach in SLE.

Slicc damage index score in systemic lupus erythematosus patients and its associated factors.

The aims of this study were to determine damage index in systemic lupus erythematosus (SLE) patients based on Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index (SDI) and to determine the laboratory and clinico-demographic factors affecting SDI.This is a retrospective cohort study of 94 SLE patients attending rheumatology clinics in 2 local hospitals in Kelantan, Malaysia. The patients were divided into 2 groups based on SDI score assigned by the attending physician, 0 (without damage) or ≥1 (with damage). Newly diagnosed SLE patients with disease duration less than 6 months were excluded.A total of 45 (47.9%) SLE patients showed damage by SDI score. Majority of the subjects had neuropsychiatric damages (21/94; 22.3%) followed by skin (12/94; 12.8%) and musculoskeletal (6/94; 6.4%) damage. SDI score was significantly associated with higher disease duration (6.2 ± 6.57 years vs 4.5 ± 3.7 years; P = .018), lower prednisolone dose (8.74 ± 10.89 mg vs 4.89 ± 3.81 mg; P < .001), hypertension (P = .007), and exposure to cyclophosphamide (P = .004). Hypertension (P = .020), exposure to cyclophosohamide (P = 0.013), and lower prednisolone dose (P = .023) were significantly associated with damage by multivariable analysis.Higher SDI score was significantly associated with exposure to cyclophosphamide, suggesting that lower cyclophosphamide doses or alternative therapeutic agents are recommended.
