Objective The objective of this study was to describe the clinical and immunological pattern and disease outcome in Egyptian systemic lupus erythematosus patients. Patients and methods The medical records of 770 systemic lupus erythematosus patients who were followed from 2002–2015 at Kasr Alainy Hospital, Cairo University, were retrospectively reviewed. Results There were 707 (91.8%) females. The mean age at disease onset was 22.1 ± 8.6 and the disease duration was 6.1 ± 4.5 years. The main clinical manifestations were mucocutaneous (90.8% with oral ulcers affecting 52.5%), arthritis (80.3%), nephritis (67.8%), hematologic involvement (64.9%), serositis (55.2%) and neuropsychiatric manifestations (44.3%). The frequencies of antinuclear antibodies were 94.3%, anti-dsDNA 74.8%, anti-Smith 11%, anticardiolipin antibodies 29.5% and lupus anticoagulant 19.8%. Infections, predominantly bacterial, affected 337 (43.8%) patients. Thirty-three (4.3%) patients died. The main causes of death were sepsis and disease activity. The five- and 10-year survival rates for the total cohort were 97.4% and 96.3%, respectively, and were 96% and 92%, respectively for those with nephritis ( p = 0.008). Autoimmune hemolytic anemia, thrombocytopenia, elevated serum creatinine, a higher damage index, infections, a higher glucocorticoid dose and cyclophosphamide use ≥ six months were associated with an increased risk of mortality with odds ratios of 3.69, p < 0.01; 4.12, p < 0.001; 1.54, p < 0.001; 1.43, p < 0.001; 5.08, p < 0.001; 5.04, p < 0.001 and 2.25, p = 0.03, respectively. Conclusion Compared to other cohorts, a relatively lower mean age at systemic lupus erythematosus onset and higher frequencies of oral ulcers, serositis and nephritis were found.

Egyptian Children

Objectives This study aims to present the manifestations of juvenile systemic lupus erythematosus (JSLE) across Egypt, to focus on age at onset and gender-driven influence on disease characteristics, and to compare findings to other countries. Methods The study included 404 Egyptian children with systemic lupus erythematosus (SLE) presenting to one of the specialized rheumatology centers corresponding to 13 major governorates. Juvenile cases age was ≤ 16°years at the time of recruitment. The SLE Disease Activity Index (SLEDAI) and damage index (DI) were assessed. Results The mean age was 13.2 ± 2.4°years; 355 females and 49 males (7.2:1), and the disease duration was 2.3 ± 1.6 years, while age at disease onset was 11.1 ± 2.5°years. Their SLEDAI was 13.5 ± 12.3, and DI, 0.36 ± 0.78. The overall estimated prevalence of childhood-SLE patients in the recruited cohort in Egypt was 1/100,000 population (0.24/100000 males and 1.8/100000 females). 7.4% developed pre-pubertal SLE (≤ 7 years); 73.3%, peri-pubertal; and 19.3% during early adolescence. The differences according to age group were equal for gender and clinical manifestations except skin lesions present in 59.3% of pre-pubertal onset, 74.6% of peri-pubertal, and 84.2% of adolescents ( p = 0.029), and renal involvement in 73.8% of peripubertal, 62.1% of pre-pubertal and 58.9% of adolescents ( p = 0.03). Laboratory investigations, SLEDAI, and DI were similar among age categories. Lupus nephritis was more common in Egypt compared to JSLE from other countries. Conclusion Our large multicenter study identified that female gender influenced disease characteristics with more frequent skin involvement. Skin lesions were significantly higher in adolescents, while renal involvement in peri-pubertal children.

Objective The aim of this study was to present the epidemiology, clinical manifestations and treatment pattern of systemic lupus erythematosus (SLE) in Egyptian patients over the country and compare the findings to large cohorts worldwide. Objectives were extended to focus on the age at onset and gender driven influence on the disease characteristics. Patients and method This population-based, multicenter, cross-sectional study included 3661 adult SLE patients from Egyptian rheumatology departments across the nation. Demographic, clinical, and therapeutic data were assessed for all patients. Results The study included 3661 patients; 3296 females and 365 males (9.03:1) and the median age was 30 years (17–79 years), disease duration 4 years (0–75 years) while the median age at disease onset was 25 years (4–75 years). The overall estimated prevalence of adult SLE in Egypt was 6.1/100,000 population (1.2/100,000 males and 11.3/100,000 females).There were 316 (8.6%) juvenile-onset (Jo-SLE) and 3345 adult-onset (Ao-SLE). Age at onset was highest in South and lowest in Cairo (p < 0.0001). Conclusion SLE in Egypt had a wide variety of clinical and immunological manifestations, with some similarities with that in other nations and differences within the same country. The clinical characteristics, autoantibodies and comorbidities are comparable between Ao-SLE and Jo-SLE. The frequency of various clinical and immunological manifestations varied between gender. Additional studies are needed to determine the underlying factors contributing to gender and age of onset differences.

Objectives: This study aims to examine the frequency and clinical association of lupus-related vasculitis in patients with systemic lupus erythematosus (SLE). Patients and methods: We retrospectively analyzed medical records of a total of 565 SLE patients (42 males, 523 females; mean age: 32.7±9.5 years; range, 13 to 63 years) between January 2017 and February 2020. Demographic, clinical data, and laboratory data and treatment modalities applied were recorded. Lupus-related vasculitis and its different types were documented, and the patients with vasculitis were compared with those without vasculitis. Results: The mean disease duration was 8.9±6.3 years. Vasculitis associated with lupus was found in 191 (33.45%) patients. Cutaneous vasculitis was found in 59.2%, visceral vasculitis in 34.0%, and both in 6.8% of total vasculitis patients. The patients with vasculitis had a longer disease duration (p=0.01), were more likely to have juvenile onset (p=0.002), livedo reticularis (p<0.001), Raynaud's phenomenon (RP) (p<0.001), digital gangrene (p<0.001), thrombosis (p=0.003), and cranial neuropathy (p=0.004). The patients with vasculitis showed a higher prevalence of hypercholesterolemia (p=0.045), diabetes mellitus (p=0.026), higher Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) at disease onset (p<0.001), and Systemic Lupus International Collaborating Clinics (SLICC) Damage Index (p=0.003) scores. They had more prevalent hematological manifestations (p<0.001), hypocomplementemia (p=0.007), received a higher cumulative dose of intravenous methylprednisolone (p<0.001), and had also more frequent cyclophosphamide (p=0.016) and azathioprine intake (p<0.001). In the logistic regression analysis, SLE vasculitis was independently associated with juvenile disease onset, livedo reticularis, RP, hematological manifestations, and higher scores of SLEDAI at disease onset (p<0.05). Conclusion: Juvenile disease onset, livedo reticularis, RP, hematological manifestations, and higher SLEDAI scores at disease onset may be associated with the development of vasculitis in SLE patients.

Background Systemic lupus erythematosus (SLE) is regarded as a prototype autoimmune disease because it can serve as a means for studying differences between ethnic minorities and sex. Traditionally, all Hispanics have been bracketed within the same ethnic group, but there are differences between Hispanics from Spain and those from Latin America, not to mention other Spanish-speaking populations. Objectives This study aimed to determine the demographic and clinical characteristics, severity, activity, damage, mortality and co-morbidity of SLE in Hispanics belonging to the two ethnic groups resident in Spain, and to identify any differences. Methods This was an observational, multi-centre, retrospective study. The demographic and clinical variables of patients with SLE from 45 rheumatology units were collected. The study was conducted in accordance with Good Clinical Practice guidelines. Hispanic patients from the registry were divided into two groups: Spaniards or European Caucasians (EC) and Latin American mestizos (LAM). Comparative univariate and multivariate statistical analyses were carried out. Results A total of 3490 SLE patients were included, 90% of whom were female; 3305 (92%) EC and 185 (5%) LAM. LAM patients experienced their first lupus symptoms four years earlier than EC patients and were diagnosed and included in the registry younger, and their SLE was of a shorter duration. The time in months from the first SLE symptoms to diagnosis was longer in EC patients, as were the follow-up periods. LAM patients exhibited higher prevalence rates of myositis, haemolytic anaemia and nephritis, but there were no differences in histological type or serositis. Anti-Sm, anti-Ro and anti-RNP antibodies were more frequently found in LAM patients. LAM patients also had higher levels of disease activity, severity and hospital admissions. However, there were no differences in damage index, mortality or co-morbidity index. In the multivariate analysis, after adjusting for confounders, in several models the odds ratio (95% confidence interval) for a Katz severity index >3 in LAM patients was 1.45 (1.038–2.026; p = 0.02). This difference did not extend to activity levels (i.e. SLEDAI >3; 0.98 (0.30–1.66)). Conclusion SLE in Hispanic EC patients showed clinical differences compared to Hispanic LAM patients. The latter more frequently suffered nephritis and higher severity indices. This study shows that where lupus is concerned, not all Hispanics are equal.

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.

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.

Objective: to assess the relationship between hematological manifestations of systemic lupus erythematosus (SLE) in the early stage of the disease and development of other syndromes and symptoms of the disease, as well as the nature and severity of internal organs damage during the subsequent five-year period.Subjects and methods. The analysis of data of examination of 89 patients with SLE during the five-year period was carried out. The frequency of clinical manifestations of SLE, the level of antinuclear and antiphospholipid antibodies, SLICC/ACR damage index (SDI) depending on the presence of hematological manifestations of SLE in the onset of the disease including leukopenia (LP), thrombocytopenia (TP) and autoimmune hemolytic anemia (AGA) were studied.Results and discussion. In the onset of SLE LP was observed in 21.3%, TP – in 26.9%, AGA – in 8.9% of patients. The presence of LP was associated with an increase of antibodies to SSA frequency, and TP – with more frequent detection of antibodies to Ro-52, cardiolipin and β-2-glycoprotein (p<0.05). Patients with TP in the onset of SLE compared with patients without hematological manifestations, had an increase (p<0.05) of the cumulative incidence of nephritis (83.3 and 42.9%), central nervous system lesions (70.8 and 26.5%), vasculitis (45.8 and 10.2%) and Libman-Sachs endocarditis (20.8 and 6.1%, respectively), which was accompanied by an increase of SDI values (median was 2.09 [2, 1.82; 2.21] and 1.12 [0.81; 1.32], p<0.05). In patients with LP, the cumulative incidence of pneumonitis and Sjogren's syndrome was increased in the onset of SLE compared with patients without hematological manifestations (15.8 vs 6.1% and 15.7 vs 2.0%, respectively, p<0.05).Conclusion. Presence of TP in the onset of SLE is a predictor of kidneys, central nervous system, peripheral vessels and heart valves damage during the next 5 years.

AbstractCD226 is an activating receptor expressed on the cell surface of natural killer cells and T cells. Although CD226 polymorphism is known to be involved in systemic lupus erythematosus (SLE), the involvement of soluble CD226 (sCD226) in SLE is still unknown. In the present study, we measured serum sCD226 levels using an enzyme-linked immunosorbent assay in 58 SLE patients and 33 healthy controls (HCs) and evaluated their associations with SLE Disease Activity Index 2000 (SLEDAI-2K), clinical manifestations, laboratory data, and the cumulative probability of flare. Serum sCD226 levels showed no significant differences between SLE patients and HCs. However, sCD226 levels were significantly elevated in active SLE patients with a SLEDAI-2K score of ≥ 20 compared with HCs. In SLE patients, sCD226 levels were significantly correlated with SLEDAI-2K scores and anti-dsDNA antibody titers. Moreover, the cumulative probability of flare was markedly higher in patients with high sCD226 than in those with low sCD226. In patients with neuropsychiatric involvement, sCD226 levels were elevated and reflected neuropsychiatric disease activity. These findings indicate that serum sCD226 levels are associated with disease activity and flares of SLE. Thus, it may be a useful biomarker for SLE, and its monitoring allows for more precise SLE management.

Objective To investigate the association of the CD11b single nucleotide polymorphism (SNP) rs1143679 with systemic lupus erythematosus (SLE) in Han Chinese patients, and to clarify this association with SLE clinical manifestations. Methods PCR–restriction fragment length polymorphism and direct sequencing of CD11b rs1143679 were conducted in 584 patients with SLE and 628 healthy controls in this case–control study to compare genotype and allele frequency distributions. Correlations between CD11b genotypes and clinical manifestations were also determined. Results The frequency of the CD11b rs1143679 GA genotype was 1.89% in Han Chinese patients with SLE, which was much lower than that of European and American populations, but close to the frequency observed in individuals from Hong Kong and Thailand. The CD11b rs1143679 GA genotype was also shown to confer susceptibility to SLE (odds ratio = 4.00, 95% confidence interval = 1.11–14.41). CD11b rs1143679 was found to be significantly associated with nephritis, but not with age of disease onset, arthritis, hematological involvement, or neural lesions. Conclusion CD11b rs1143679 appears to be associated with risk for SLE in the Han Chinese population, and may play an important role in the development of lupus nephritis.
