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.

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease involving multiple organ systems. The kidney appears to be the most commonly affected organ, especially nephrotic is a serious kidney injury. The clinical, laboratory manifestations and histopathology are very useful for diagnosis, provide the means of predicting prognosis and guiding therapy in nephrotic patients with lupus nephritis. Methods: Descriptive cross-sectional study of nephrotic patients with lupus treated in the Department of Nephrology Trung Vuong Hospital and Cho Ray Hospital between May/2014 and May/2017. Renal histopathological lesions were classified according to International Society of Nephrology/Renal Pathology Society - ISN/RPS ’s 2003. The clinical, laboratory manifestations and histopathological features were described. Results: Of 32 LN with nephritic range proteinuria cases studied, 93.7% were women. The 3 most common clinical manifestations were edema (93.8%), hypertension (96.8%) and pallor (68.9%), musculoskeletal manifestions (46.9%), malar rash (40.6%). There was significant rise in laboratory and immunological manifestions with hematuria (78.1%), Hb < 12g/dL (93.5%), increased Cholesterol (100%), and Triglycerid (87.5%), Creatinine > 1.4 mg/dL (87.5%), increased BUN 71.9%, ANA (+) 93.8%, Anti Ds DNA(+) 96.9%, low C3: 96.9%, low C4: 84.4%. The most various and severe features were noted in class IV with active tubulointerstitial lesions and high activity index. Conclusion: Lupus nephritis with nephrotic range proteinuria has the more severity of histopathological feature and the more severity of the more systemic organ involvements and laboratory disorders were noted. Key words: Systemic lupus, erythematosus (SLE) lupus nepphritis, clinical

Interferon System

The interferon system (IFN) is a group of signaling molecules with antiviral, antitumor and antiproliferative effects. The most studied signaling pathway is mediated by IFN type I. Mutations of IFN-I-regulated genes are involved in the pathogenesis of systemic lupus erythematosus (SLE). Interferon index (IFN-I-index) – a quantitative indicator of the level of expression of IFN-Iregulated genes – is used to assess the activity of the interferon system. Objective of the study: to assess the level of the IFN-I index in children with SLE, as well as to compare the clinical and laboratory characteristics of patients with high and normal levels of the IFN-I-index. Materials and methods of research: 40 patients (girls – 83%, boys – 17%) under 18 years of age with SLE diagnosed in accordance to the SLICC 2012 criteria were included in a multicenter prospective open uncontrolled nonrandomized continuous study. The age of the patients was 15,2 (12,5 ; 16,7) years. All of them underwent examination and treatment in the Pediatric department № 3 at the clinic of the St. Petersburg State Pediatric Medical University and in the Pediatric department of the Almazov National Medical Research Center. The IFN-I index was determined by real-time PCR with a quantitative assessment of the expression of 5 genes induced by IFN-α and β. Results: aggravated family history of rheumatic diseases was noted in 8 patients: SLE – in 3 (8%), rheumatoid arthritis – in 3 (8%), cold urticaria – in 2 (5%). The average age of onset of the disease is 12 years. The most common clinical manifestations were lesions of the skin, joints, mucous membranes, central nervous system, kidney and fever. 31 patients (78%) had an increased IFN-I index. All cases of kidney failure were observed only in patients with a high IFN index (36% vs 0%, p=0,036). Patients with increased IFN-I-index had statistically significant increased levels of antinuclear (87% vs 56%, p=0,043) and rheumatoid factors (36% vs 0%, p=0,036), higher ECLAM index values (3,0 vs 1.0, p=0,048), ferritin levels (p=0,0008) and, as a consequence, the need for more intensive immunosuppressive therapy (using rituximab and cyclophosphamide) compared with patients with normal IFN-Iindex. A positive statistically significant correlation of the IFN-I index with male sex (r=0,41, p=0,008), nephritis (r=0,35, p=0,026), livedoid rash (r=0,38, p=0,017 ), Raynaud's phenomenon (r=0,37, p=0,018), high antinuclear factor (r=0,82, p=0,001), rheumatoid factor (r=0,654, p=0,011), antibodies to Sm antigen (r=0,57, p=0,034), as well as a negative relationship with anemia (r=–0,67, p=0,009). Conclusion: IFN-I-index can be considered as a surrogate biomarker of activity and prognosis of SLE. Further research is required to validate its diagnostic role.

Background The concomitant presence of two autoimmune diseases – systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) – in the same patient is known as rhupus. We evaluated a group of patients with rhupus to clarify further their clinical, serological and immunogenic features in a multi-centre cohort. In addition, the study aimed to explore the utility of the 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) SLE classification criteria in our group of patients with rhupus. Methods This was a cross-sectional study. We included rhupus patients from 11 different rheumatology departments, and compared them to SLE and RA patients at a ratio of 2:1. All information was recorded following a pre-established protocol. Results A total of 200 patients were included: 40 rhupus patients and 80 each of SLE and RA patients as controls. Disease duration was similar among SLE and rhupus groups (around 13 years), but the RA group had a significantly lower disease duration. Main clinical manifestations were articular (94.2%), cutaneous (77.5%) and haematological (72.5%). Rhupus patients had articular manifestations similar to those expected in RA. Only 10% of rhupus patients had renal involvement compared with 25% of those with SLE ( p < 0.05), while interstitial lung disease was more common in patients affected by RA. The 2019 EULAR/ACR SLE criteria were met in 92.5% of the rhupus patients and in 96.3% of the SLE cohort ( p > 0.05). Excluding the joint domain, there were no differences between the numbers of patients who met the classification criteria. Conclusion Rhupus patients follow a particular clinical course, with full expression of both SLE and RA in terms of organ involvement, except for a lower prevalence of kidney affection. The new 2019 EULAR/ACR SLE criteria are not useful for differentiating SLE and rhupus patients. A new way of classifying autoimmune diseases is needed to identify overlapping clusters.

Objective: To describe the prevalence of neuropsychiatric (NP) syndromes in a Finnish population of patients with systemic lupus erythematosus (SLE) and to classify them according to the recently developed American College of Rheumatology (ACR) nomenclature and case definitions for NPSLE.Methods: Cross-sectional, population-based study covering an area with 440,000 people. A total of 58 patients with a definite diagnosis of SLE and aged 16 to 65 years were found in the computerized database of the area hospitals. Of these, 46 (79%) agreed to participate. The diagnosis of various NP syndromes was based on clinical impression (H.A.) following history, examination, review of medical records, and neuropsychologic testing.Results: At least one NP syndrome was identified in 42 patients (91%). The most frequent manifestation was cognitive dysfunction (n = 37; 81%), followed by headache (n = 25; 54%) and mood disorder (n = 20; 43%). When mild NP syndromes (mild cognitive deficit, headache, mild depression, anxiety, electroneuromyography-negative polyneuropathy) were excluded, the prevalence of NPSLE dropped to 46%.Conclusions: According to the ACR nomenclature, there is a high prevalence of NP manifestations in a population-based sample of patients with SLE. Most NP syndromes were classified as minor; if they were excluded, the 46% prevalence of NPSLE would be slightly less than estimated in previous studies.

Background: Systemic lupus erythematosus (SLE) is an autoimmune condition with a wide spectrum of clinical manifestations encompassing most organs and systems. Its treatment approach includes different immunomodulatory treatments, of which B-cell targeted therapies are part of. Rituximab (an anti-CD20 antibody) had encouraging results in observational studies but failed when tested in clinical trials. It is theorized that this could have been partially due to BAFF upregulation, leading to rituximab failure. Therefore, targeting BAFF with belimumab after rituximab therapy, may have a synergic effect in SLE. Objective: We review the available observational data regarding sequential rituximab/belimumab therapy in SLE patients. Results: Twenty-four patients from 6 studies were included. The results suggest a benefit with this combined therapy, with reduction of the mean SLEDAI. However, there was significant drug regimen and patient selection heterogeneity. Conclusion: Further randomized clinical trials are needed to examine this drug sequencing protocol in SLE patients.

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.

The aim was to explore possible correlations of antibodies to extractable nuclear antigens (ENA) with clinical manifestations and disease activity indices in systemic lupus erythematosus (SLE) patients. A total of 70 consecutive SLE patients (64 females) were included. Disease activity was assessed by SLE activity index (SLEDAI), and British Isles Lupus Assessment Group (BILAG). Anti-Ro/SSA correlated positively with, headache (r=0.24, p=0.04), blurring of vision (r=0.25, p=0.03) and SLEDAI (r=0.25, p=0.04) and negatively with C3 (r=–0.35, p=0.003). Anti-Ro/SSA correlated with anti La/SSB antibodies (r=0.69, p<0.001), but not with anti-DNA, anti-RNP and anti-Sm antibodies. Anti-La/SSB antibodies correlated with headache (r=0.26, p=0.03), SLEDAI (r=0.25, p=0.03) and negatively with C3 (r=–0.34, p=0.004). Anti-La/SSB did not correlate with anti-RNP or anti-Sm antibodies. Anti-Sm antibodies correlated with disease duration (r=0.34, p=0.003), 24 hours urinary proteins (r=0.31, p=0.008), SLEDAI (r=0.31, p=0.009), BILAG renal score (r=0.29, p=0.02) and negatively with age at onset (r=–0.27, p=0.02), WBCs (r=–0.29, p=0.014) and C4 (r=–0.25, p=0.049). In multivariate analyses, anti-Ro/SSA antibodies remained associated with headache, blurring of vision and C3 and anti-La/SSB antibodies remained associated with C3 and with headache. Anti-Sm antibodies were independently associated with disease duration and total SLEDAI scores, while anti-RNP antibodies remained significantly associated with BILAG mucocutaneous scores only. Antibodies to ENAs are associated with clinical aspects of SLE and may play a role in the assessment of disease activity. Insight into these ENAs may lead to new approaches to diagnostic testing, accurate evaluation of disease activity and lead to target approach for SLE.

The complement system contributes to the pathogenesis of systemic lupus erythematosus (SLE). Mannose-binding lectin (MBL) is a key molecule of the lectin pathway of complement and seems to be related to the clinical manifestations of this disease. We evaluated the serum levels of MBL and its relationship with disease onset and clinical findings in SLE patients. Serum samples were analysed in 195 patients and 145 healthy controls from southern Brazil. Patients with high MBL levels (above 2000 ng/ml) showed a significant increase in the frequency of thrombocytopaenia ( p = 0.007; OR = 2.71; 95% CI = 1.32–5.55); and seizures ( p = 0.034; OR = 2.61; 95% CI = 1.07–6.37). A positive correlation between disease activity and MBL levels (>2000 ng/ml; p = 0.031, rho = 0.279) as well as of MBL concentration with accumulated organ damage ( p = 0.021; rho = 0.232) was observed. Our results suggest a role for MBL in the development of clinical manifestations such as thrombocytopaenia and seizures in SLE patients. These findings corroborate the participation of the lectin pathway of complement in the pathophysiologic mechanisms underlying clinical manifestations of SLE.
