The ubiquitous human polyomaviruses BK (BKV) and JC (JCV) persist with no adverse effects in immunocompetent individuals. Virus-induced pathogenesis has been linked to virus reactivation during impaired immune conditions. Previous studies have shown a significant difference between the VP1 DNA sequences of JCV obtained from control urine samples and those in progressive multifocal leukoencephalopathy brain samples. This difference could not be detected when comparing normal control urinary JCV DNA with DNA sequences from chronic progressive multiple sclerosis patients. Since BKV and JCV are readily activated in systemic lupus erythematosus (SLE) patients, the presence of specific strains, related to VP1 DNA sequences, was investigated in these patients. VP1 DNA sequences in 100 urine samples from 21 SLE patients and 75 urine samples from 75 healthy pregnant women were analysed and compared to previously reported sequences. The results show that the VP1 sequence profiles of JCV and BKV excreted by SLE patients do not differ significantly from those excreted by immunocompetent individuals. The European JCV subtypes 1A or 1B were represented among all JCV-positive urine specimens, while BKV VP1 sequences showed complete, or almost complete, identity with the MM or JL strains. Different urine samples from the same patient collected over a 1 year period were predominantly stable. BKV VP1 DNA in urine specimens from healthy pregnant women was only detected during the third trimester of their pregnancy. These results argue against SLE-specific JCV and BKV strains and suggest reactivation of the viruses rather than recurrent re-infections of patients with SLE.

Introduction Systemic lupus erythematosus has a predilection for women of childbearing age. Globally a shortage of rheumatologists exists resulting in general physicians and obstetricians treating systemic lupus erythematosus in pregnancy. Methods We conducted a survey amongst medical and obstetric registrars in South Africa to assess their subjective and objective competence in managing pregnant women with systemic lupus erythematosus. Results The pass rate for the objective section was 70.8% with no statistically significant difference in the pass rate between medical and obstetric registrars. Participants felt unprepared to manage pregnant women with systemic lupus erythematosus, with a mean overall score of 3.4 out of 7 for the subjective section, based on four Likert scale type questions. Conclusion Trainees are not able to accurately assess their own levels of competence in order to identify their learning needs. Due to the shortage of rheumatologists and lack of obstetric physicians in South Africa, general physicians and obstetricians must be equipped to provide adequate care to pregnant women with systemic lupus erythematosus.

Background:Pregnant women with systemic lupus erythematosus (SLE) are at high risk of preeclampsia, leading to substantial maternal and fetal morbidity. Aspirin reduces preeclampsia risk but recent studies suggest aspirin is used only in a minority of SLE pregnancies. There is an urgent need to improve preeclampsia counselling and management in this vulnerable population.Objectives:We are conducting the PREPARE (PREeclamPsia knowledge & Aspirin adheRence in lupus prEgnancies) trial, a randomized controlled trial (RCT) evaluating an educational tool on preeclampsia knowledge and aspirin adherence among pregnant women with SLE. We present preliminary analyses of the effect of this tool on preeclampsia knowledge.Methods:Consecutive pregnant SLE women are recruited until the 16th gestational week at 5Canadian Systemic Lupus International Collaborating Clinics centres (i.e. Montreal, Halifax, Quebec, Winnipeg, and Calgary) since 05/2018. Subjects are randomly assigned to receive either the specifically-designed educational tool (intervention group) or standard of care (control group). At baseline (i.e. first trimester) and second trimester visits, the participants complete self-administered preeclampsia knowledge questionnaires (scored out of 30 by the research team blinded to the intervention). We restricted the current analysis to participants enrolled in Montreal (accounting for nearly half of the total planned sample size). We performed a univariate linear regression analysis to assess the effect of the educational tool on preeclampsia knowledge (i.e. mean score difference between the two groups from baseline to second trimester visit).Results:Thirty-three pregnant SLE women were included in the study, among which 16 were exposed to the intervention and 17 were unexposed. Baseline characteristics were well balanced between the two groups with similar mean maternal age between intervention group (32.2 years, standard deviation, SD, 4.6) and control group (34.1 years, SD 4.2) and identical proportion of subjects with post-secondary education (i.e. 80%). The difference in mean preeclampsia knowledge scores between second trimester and baseline visits in the intervention group was 4.4 points (95% CI -0.1, 9.0) and in the control group was 1.5 points (95% CI -2.7, 5.7). The mean difference in knowledge scores (from baseline to second trimester) for those receiving the educational tool was 2.7 points higher (95% CI -1.5, 6.9) than those receiving standard of care.Conclusion:Approximately midway into the PREPARE trial, we observed a trend for improvement in preeclampsia knowledge from the baseline to the second trimester visit in pregnant women with SLE who received a specifically-designed educational tool compared to the control group, although the CIs included the null. Our RCT is well-poised to provide a new evidence-based approach to improve preeclampsia knowledge in pregnant women with SLE, which could help to optimize aspirin use and outcomes in this vulnerable population.References:[1]Schramm AM, Clowse ME.

Background:Systemic lupus erythematosus (SLE) has a significant genetic predisposition. Many genetic variants of susceptibility to SLE have been published and analyzed, but the clinical and functional significance of the various genotypes has not yet been clearly defined [1].Objectives:To estimate the association between some of non-HLA gene polymorphisms such as STAT4 rs7574865, RUNX1 rs9979383, IL6 rs1800795, IL6R rs2228145, IL6R rs4845618 and susceptibility to SLE in Belarusian population as well as some disease manifestations.Methods:We examined 383 healthy blood donors and 54 SLE patients (18-72 years old, median age 35) classified according to the 1997 American College of Rheumatology (ACR) revised classification criteria [2]. Deoxyribonucleic acid was extracted from peripheral blood samples by phenol-chloroform method. Genotyping was performed by real-time PCR with fluorescent probes. Differences of distribution of all the single nucleotide polymorphism (SNP) genotypes and their associations with secondary antiphospholipid syndrom (APS) and lupus arthritis were analyzed using Pearson χ2 (χ2) and two-way Fisher exact test (F, p2-t). Diagnostic odds ratio (dOR), likelihood ratio of positive (LR +) and negative (LR –) tests and corresponding 95% confidence intervals (CI) were also calculated.Results:We revealed significant difference in STAT4 rs7574865 genotypes in SLE patients and healthy donors (χ2=8,27, р=0,016) with significant increase of ТТ genotype frequency in SLE patients vs healthy donors (χ2=6.83 p=0.009; p2-t =0.020; dOR=3.78 (CI95% 1.36-10.55); LR+ =3.44 (CI95% 1.35-8.71); LR– =0.91 (CI95% 0.83-0.98)). Lupus arthritis was more common in risk TT-genotype SLE carriers than in other SLE patients (χ2=5.902 p=0.015; p2-t =0.027).We revealed significant increase of СТ genotype (RUNX1 rs9979383) in healthy donors vs SLE patients (χ2=4.14; p=0.042; dOR=0.53 (CI95% 0.29-0.98); LR+ =0.69 (CI95% 0.45-0.99); LR– =1.3 (CI95% 1.01-1,56)). Lupus arthritis was more common in SLE СТ-genotype carriers than in other SLE patients (χ2=4.66 p=0.031; p2-t =0.058).Significant differences in IL6 rs1800795, IL6R rs2228145 and IL6R rs4845618 genotypes distribution between studied groups were not found (χ2, p=0.427, p=0.559 and p=0.407, correspondingly) but GG-genotype (IL6 rs1800795) carriership in SLE patients was associated with increased APS frequency (χ2=4.45, p=0.035; dOR=0.19 (CI95% 0.04-0.9); LR+ =0.28 (CI95% 0.07-0.93); LR– =1.41 (CI95% 1.03-1.64).Conclusion:Our data suggest the susceptibility to SLE in ТТ genotype of STAT4 rs7574865 polymorphism, protective role of СТ genotype of RUNX1 rs9979383 for SLE and association between GG-genotype of IL6 rs1800795 and APS in SLE patients in Belarusian population. Lupus arthritis was associated with ТТ genotype of STAT4 rs7574865 and СТ genotype of RUNX1 rs9979383.References:[1]Chen L, Morris DL, Vyse TJ.

Objective The need for a biomarker with robust sensitivity and specificity in diagnosing systemic lupus erythematosus (SLE) remains unmet. Compared with blood samples, urine samples are more easily collected; thus, we aimed to identify such a biomarker based on urinary proteomics which could distinguish patients with SLE from healthy controls (HCs). Methods Urine samples were collected from 76 SLE patients who visited rheumatology clinic in 2019 at Asan medical center and from 25 HCs. Urine proteins were analyzed using sequential windowed acquisition of all theoretical fragment ion spectra-mass spectrometry, and the candidate marker was confirmed by enzyme-linked immunosorbent assay (ELISA). Receiver operating characteristic curve analysis was used to determine the diagnostic value of the candidate biomarker. Results Of 1157 proteins quantified, 153 were differentially expressed in urine samples from HCs. Among them were previously known markers including α-1-acid glycoprotein 1, α-2-HS-glycoprotein, ceruloplasmin, and prostaglandin-H2 D-isomerase. Moreover, the amount of β-2 glycoprotein (APOH) was increased in the urine of patients with SLE. The ELISA results also showed the level of urine APOH was higher in patients with SLE than in HCs and patients with rheumatoid arthritis. Moreover, the level was not different between SLE patients with and without nephritis. The urine APOH had an area under the curve value of 0.946 at a cut-off value of 228.53 ng/mg (sensitivity 91.5%, specificity 92.0%) for the diagnosis of SLE. Conclusion The results indicate that the urine APOH level can be an appropriate screening tool in a clinical setting when SLE is suspected.

Abstract Background Pediatric Systemic Lupus Erythematosus (pSLE) is a chronic mutisystemic autoimmune disease with complex clinical manifestations whose diagnosis is not always easy and the course is generally severe and the treatment is not very well codified and often extrapolated from that of adults. This study aims to describe the clinical, immunological, therapeutic characteristics and short outcome of systemic lupus erythematosus in Algerian children. Methods This was a prospective, multicentre and descriptive study 36 months (January 2015 - December 2018) at the department of Pediatrics of University Hospital Nefissa Hamoud ex Parnet Algiers. Children less than16 years of age fulfilling the American College of Rheumatology SLE criteria were included. Disease activity estimated by Systemic Lupus Erythematosus Disease Activity index (SLEDAI) whose use has been validated in children and damage index based on Systemic Lupus International Collaborating Clinics (SLICC) score were determined. Results Eighty-three (83) patients were studied. Female: male ratio was1:49. Mean ages at lupus onset and diagnosis were respectively: 10, 12 ± 3, 88 and 11, 3 ± 3, 62 years. All patients had skin involvement while constitutional signs including fever and asthenia were observed in (98.8%). Rheumatological, renal, neuropsychiatric, cardiac, hepato-digestive, pleuropulmonary and ocular disorders were observed respectively: 65, 1%, 44, 6%, 41%, 27, 7%, 41%, 19, 3% and 7, 2%. All patients were positive for antinuclear antibodies. Anti-double-stranded DNA (75%) was the most frequently observed autoantibody profile. Antiphospholipid antibody positivity was noted in 52% whereas hypocomplementemia in fractions C3, C4 was observed in 55% and 56% respectively. In our study, the severe forms were more frequent (83%) than the mild ones (17%) with a significant difference (P = < 10–6). Overall, the mean SLEDAI at disease onset was 22.11 ± 11.87 with high activity ≥ 20 in 59% of cases. The mean damage score was 1.8 ± 2.045 (interquartile range 0–8). Among induction drugs, oral corticosteroids were the most frequently used (92%), and in a third of cases intravenously at high doses in combination with immunosuppressive therapy. In induction therapy, cyclophosphamide (CYC) was the most used drug (23%) compared with mycophenolate mofetil (MMF) (14%). Unlike the maintenance phase where MMF observed an increase (28%) vs (8%) CYC. The use of MMF was correlated with severe lupus nephritis with a significantly effective difference in the decrease in SLEDAI (P = 0.0001). The use of hydroxychloroquine (HCQ) was observed in 81% in induction and 89% in maintenance treatment. The correlation of HCQ use with survival was significantly positive (P = 0.04). Indeed, adherence to treatments and essentially HCQ was a protective factor, its odds ratio is < 1 with a significant p-value, [OR 0.016 95% CI (0.001–0.353)]. Mortality was estimated at 11%. Multivariable regression analysis showed that the neurological involvement (odds ratio = 6,093 95% confidence interval ((1,1 8 0 ∼ 31 446)) and macrophage activation syndrome were associated with a high risk of mortality. Conclusion we report a series of pSLE characterized by great clinical and biological heterogeneity. It follows a severe course of the disease with high disease activity at the diagnosis and therefore leads to high morbidity and mortality. However, these results must be confirmed by other pediatric studies which could form the basis of a diagnostic and therapeutic approach more adapted for children.

Background : Low level of vitamin D impact the disease activity and the degree of fatigue in SLE patients. This study aims to determine the effect of vitamin D supplementation on disease activity and fatigue condition in Systemic Lupus Erythematosus (SLE) patients with hipovitamin D.Methods: We performed an open clinical trial. Subjects were randomized into two different groups (supplementation or placebo) using simple random sampling. The treatment group got vitamin D3 softgel/ cholecalciferol 1200 IU/day or 30 mg/day, while the control group gotplacebo for 3 months. SLEDAI scores and FSS scores were calculated at pre and posttreatment.Results: There were 20 subjectsfor supplementation group and 19 subjects in the placebo group. From this study, before and after treatment, we found a significant difference of mean level of vitamin D in supplementation group (p=0.000), and no significant difference inpatients with placebo (p=0.427). Moreover, from the SLEDAI score analysis, observed a significant difference bothin the supplemented group (p=0.000) and the placebo group (p=0.006). FSS scores significantly different in the supplemented group (p=0.000). Incorrelation test,there was a negative correlation (r=-0763) between vitamin D level and disease activity (SLEDAI), and both showing stastistical significance between thepre supplementation (p=0.000) and post supplementation (r=-0846; p=0.000). Similarly to theFSS scores, there was a meaningfulnegative correlation (r=-0.931, p=0.000) between the level of vitamin D with FSS scores pre and post supplementation (r=-0.911; p= 0.000). Furthermore, there was a significant correlation between disease activity (SLEDAI) pre supplementation with fatigue condition pre supplementation (r=0.846; p = 0.000) and postsupplementation (r=0.913; p= 0.000).Conclusion: The supplementation of vitamin D 1200 IU per day in patients with SLE improve disease activity and degree of fatigue.

Background: Designation of disease activity is serious for the management of systemic lupus erythematosus (SLE). Serum level of β2 microglobulin (β2M) may be associated with illness activity in SLE disease. Since the role of β2M for assessing of illness activity in SLE is not completely clear, the current study aimed to discern evaluation of β2M in patients with SLE and its correlation with sickness activity. Materials and Methods: In this case-control study, 50 patients with SLE disease and 25 healthy individuals were selected in Imam Khomeini Hospital in central of Urmia. Blood samples were collected safely from patients, serum was removed, and β2M measured using an ELISA method. The results for other parameters including C reactive protein, C3, C4, anti dsDNA and erythrocyte sedimentation rate were obtained from patients’ medical record. Data analyzed using appropriate statistical tests including Mann-Whitney U test, Independent f-test, Kruskal-Wallis, and Spearman used for analysis of data. Results: In the current study, a significant difference was seen between two groups in terms of β2M (p < 0.001). Remarkable correlation was seen between the level of β2M with disease activity (p < 0.001). Furthermore, there are significant relevancy between the level of β2M with 24-hour urine protein, ESR, disease activity score, and CRP (p < 0.05). Conclusion: The results revealed that serum amount of β2M in SLE patients is higher compared to healthy ones, which is significantly correlated to score of illness activity, CRP, and ESR in patients with SLE disease. Hence β2M might be an excellent serological marker helping the prediction of sickness activity and inflammation in SLE patients.

Objective The objective of this study was to determine the association between disease activity status and health-related quality of life (HRQoL) in systemic lupus erythematosus (SLE) patients. Methods SLE patients in an out-patient clinic during the previous 12 months were included in the study. The Systemic Lupus Erythematosus-specific Quality-of-Life questionnaire (SLEQoL) was administered at the last visit. Disease activity status was determined retrospectively during the previous year. The categories of disease activity status were defined as: clinical remission (CR): clinical quiescent disease according to Systemic Lupus Erythematosus Disease Activity Index 2000, prednisolone ≤ 5 mg/day; low disease activity (LDA): SLEDAI-2K (without serological domain) ≤ 2, prednisolone ≤ 7.5 mg/day; and non-optimally controlled status: for those who were not in CR/LDA. Immunosuppressive drugs (maintenance dose) and antimalarials were allowed. Prolonged CR or LDA was defined as those with sustained CR or LDA for at least one year. The association between disease activity status and HRQoL was assessed by using regression analysis adjusting for other covariates. Results Of 237 SLE patients, 100 patients (42.2%) achieved prolonged CR, 46 patients (19.4%) achieved prolonged LDA and 91 patients (38.4%) were not in CR/LDA. Non-CR/LDA patients had significantly higher total SLEQoL score and in all domains compared to CR/LDA patients. No significant difference in SLEQoL domain scores was found between CR and LDA groups. Multivariable analysis revealed that non-CR/LDA was positively associated with SLEQoL score compared with CR/LDA (β 20.02, 95% confidence interval (CI) 6.81–33.23, p < 0.003). Moreover, non-CR/LDA was at a higher risk of impaired QoL (SLEQoL score > 80) compared with CR (hazard ratio 3.8; 95% CI 1.82–7.95; p < 0.001). However, there was no significant difference between CR and LDA in terms of SLEQoL score or impaired QoL. Other factors associated with higher SLEQoL score were damage index (β 9.51, 95% CI 3.52–15.49, p = 0.002) and anemia (β 24.99, 95% CI 5.71–44.27, p = 0.01). Conclusion Prolonged CR and LDA are associated with better HRQoL in SLE patients and have a comparable effect. Prolonged CR or optional LDA may be used as the treatment goal of a treat to target approach in SLE.
