Background:Complement is strongly implicated in the pathogenesis of autoimmune diseases like systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Its component C1q plays a dualistic role, triggering the inflammatory cascade on one hand and directing the clearance of immune complexes on the other. Homozygous genetic deficiency of C1q is strongly associated with SLE and SLE-like phenotype as almost 90% of C1q deficient individuals develop SLE or similar disease. Nevertheless, there are few and inconsistent studies exploring the single nucleotide polymorphisms (SNPs) of the C1q gene cluster in relation to the pathogenesis of SLE and RA.Objectives:The aim of the study was to evaluate the possible association of five SNPs – rs292001, rs172378, rs294179, rs665691 and rs682658 in complement C1q gene cluster with susceptibility to SLE and RA in Bulgarian cohort.Methods:Fifty patients with SLE, sixty-one patients with RA and sixty-seven healthy controls were genotyped for the five SNPs by TaqMan allelic discrimination assay.Results:Frequency of genotypes and alleles of rs294179, rs665691 and rs682658 SNPs was similar between patients with SLE, RA and healthy controls. For rs172378 SNP, the minor G allele (OR = 2.73; 95% CI, 1.59-4.67, p=0.0003) and GG genotype (OR = 5.12; 95% CI, 1.60-16.49, p=0.006) were associated with susceptibility to RA. In our cohort in accordance with others, AA rs292001 SNP genotype was associated with increased risk for RA (OR = 3.32; 95% CI, 1.19-9.20, p=0.021). For SLE patients, AA rs292001 SNP genotype was low presented and did not associate with disease.Conclusion:GG genotype of rs172378 SNP in C1q gene cluster could be considered as a new risk factor for RA.References:[1]Diane Scott et al (2016).

Necrosis Factor Alpha

Autoimmune diseases (AIDs) are complex diseases characterized by persistent or recurrent inflammation, alteration of immune response, and production of specific autoantibodies. It is known that different AIDs share several susceptibility genetic loci. Tumor necrosis factor alpha inducible protein 3 (TNFAIP3) encodes the ubiquitin-modifying enzyme A20, which downregulates inflammation by restricting NF-κB, a transcription factor that regulates expression of various proinflammatory genes. Variants in TNFAIP3 gene have been described as associated with susceptibility to several AIDs. Here, we analyzed two TNFAIP3 polymorphisms in Italian patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and primary Sjogren’s syndrome (pSS), to verify if the genetic variability of TNFAIP3 gene is involved in genetic predisposition to AIDs also in the Italian population. We recruited 313 SLE patients, 256 RA patients, 195 pSS patients, and 236 healthy controls. Genotyping of rs2230926 and rs6920220 in TNFAIP3 gene was performed by an allelic discrimination assay. We carried out a case/control association study and a genotype/phenotype correlation analysis. A higher risk to develop SLE was observed for rs2230926 (P=0.02, OR=1.92). No association was observed between this SNP and the susceptibility to pSS or RA. However, the rs2230926 variant allele seems to confer a higher risk to develop lymphoma in pSS patients, while in RA patients, the presence of RF resulted significantly associated with the variant allele. Regarding the rs6920220 SNP, we observed a significant association of the variant allele with SLE (P=0.03, OR=1.53), pSS (P=0.016, OR=1.69), and RA (P=0.0001, OR=2.35) susceptibility. Furthermore, SLE patients carrying the variant allele showed a higher risk to develop pericarditis, pleurisy, and kidney complications. Our results support the importance of the TNFAIP3 gene variant role in the development of different autoimmune diseases in the Italian population and furtherly confirm a sharing of genetic predisposing factors among these three pathologies.

SummaryRheumatic autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus (SLE), are associated with antibodies to “self” antigens. Persons with autoimmune diseases, most notably SLE, are at increased risk for developing accelerated cardiovascular disease. The link between immune and inflammatory responses in the pathogenesis of cardiovascular disease has been firmly established; yet, despite our increasing knowledge, accelerated atherosclerosis continues to be a significant co-morbidity and cause of mortality in SLE. Recent animal models have been generated in order to identify mechanism(s) behind SLE-accelerated atherosclerosis. In addition, clinical studies have been designed to examine potential treatments options. This review will highlight data from recent studies of immunity in SLE and atherosclerosis and discuss the potential implications of these investigations.

ObjectivesPatients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) have increased risk of cardiovascular disease (CVD). We investigated whether single nucleotide polymorphisms (SNPs) at autoimmunity risk loci were associated with CVD in SLE and RA.MethodsPatients with SLE (n=1045) were genotyped using the 200K Immunochip SNP array (Illumina). The allele frequency was compared between patients with and without different manifestations of CVD. Results were replicated in a second SLE cohort (n=1043) and in an RA cohort (n=824). We analysed publicly available genetic data from general population, performed electrophoretic mobility shift assays and measured cytokine levels and occurrence of antiphospholipid antibodies (aPLs).ResultsWe identified two new putative risk loci associated with increased risk for CVD in two SLE populations, which remained after adjustment for traditional CVD risk factors. An IL19 risk allele, rs17581834(T) was associated with stroke/myocardial infarction (MI) in SLE (OR 2.3 (1.5 to 3.4), P=8.5×10−5) and RA (OR 2.8 (1.4 to 5.6), P=3.8×10−3), meta-analysis (OR 2.5 (2.0 to 2.9), P=3.5×10−7), but not in population controls. The IL19 risk allele affected protein binding, and SLE patients with the risk allele had increased levels of plasma-IL10 (P=0.004) and aPL (P=0.01). An SRP54-AS1 risk allele, rs799454(G) was associated with stroke/transient ischaemic attack in SLE (OR 1.7 (1.3 to 2.2), P=2.5×10−5) but not in RA. The SRP54-AS1 risk allele is an expression quantitative trait locus for four genes.ConclusionsThe IL19 risk allele was associated with stroke/MI in SLE and RA, but not in the general population, indicating that shared immune pathways may be involved in the CVD pathogenesis in inflammatory rheumatic diseases.

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.

Polyautoimmunity is one of the major clinical characteristics of autoimmune diseases (ADs). The aim of this study was to investigate the prevalence of ADs in spondyloarthropathies (SpAs) and vice versa. This was a two-phase cross-sectional study. First, we examined the presence of ADs in a cohort of patients with SpAs (N=148). Second, we searched for the presence of SpAs in a well-defined group of patients with ADs (N=1077) including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Sjögren’s syndrome (SS). Among patients with SpAs, ankylosing spondylitis was observed in the majority of them (55.6%). There were two patients presenting with SS in the SpA group (1.4%) and 5 patients with autoimmune thyroiditis (3.5%). The global prevalence of ADs in SpAs was 4.86%. In the ADs group, there were 5 patients with SpAs (0.46%). Our results suggest a lack of association between SpAs and ADs. Accordingly, SpAs might correspond more to autoinflammatory diseases rather than to ADs.

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.

Aim: We aimed to identify differentially expressed Long noncoding RNAs (lncRNAs) and explore their functional roles in systemic lupus erythematosus (SLE). Materials & methods: We identified dysregulated lncRNAs and investigated their prognostic values and potential functions using MiRTarget2, catRAPID omics and Bedtools/blast/Pearson analyses. Results: Among the 143 differentially expressed lncRNAs, TCONS_00483150 could be used to distinguish patients with SLE from healthy controls and those with rheumatoid arthritis and patients with active/stable SLE from healthy controls. TCONS_00483150 was significantly correlated with anti-Rib-P antibody positivity and low C3 levels; TCONS_00483150 dysregulation might contribute to the metabolism of RNA and proteins in SLE patients. Conclusion: Overall, our findings offer a transcriptome-wide overview of aberrantly expressed lncRNAs in patients with SLE and highlight TCONS_00483150 as a potential novel diagnostic biomarker.

Abstract Introduction. Autoimmune diseases are a family of more than 100 heterogeneous conditions that affect 5 to 8% of the world’s population. The etiology is still un-known but the disregulation of the regulatory T-lymphocytes play a central role inthe autoimmunity and the success of the long-term remission. Although conventional immunosuppression and new biological agents can provide disease control in severely affected patients, such treatments are rarely curative and alternative strategies are needed. Indeed, severe forms of systemic autoimmune diseases, such as multiple sclerosis (MS), systemic sclerosis (SSc), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), juvenile idiopathic arthritis (JIA), hematologic immune cytopenia (HIC) and Crohn’s disease are difficult to be treated. High-dose immunosuppressive therapy followed by autologous stem cells transplantation is reliable option for a successive treatment of this group of patients. Aim. To determine the safety of the procedure of autologous stem cell transplantation in patients with autoimmune diseases and concomitant malignant hematological disorders. Methods. During a period of 15 years (from September 2000 to September 2015) at the University Clinic of Hematology in Skopje we have treated 6 patients with autoimmune disease and concomitant hematological neoplasm. None of the patients was treated for primary autoimmune diseases. Two men and 4 women, with median age of 47 years were treated. Sjogren syndrome and multiple myeloma were found in 2 patients, polyartheritis nodosa and multiple myeloma in 1 patient, rheumatoid arthritis and acute myeloblastic leukemia in 1, systemic lupus erythematosus and non-Hodgkin lymphoma in 1; severe psoriasis and acute myeloblastic leukemia in 1 patient. Results. All treated patients are alive after trans-planted procedure, with transplant related mortality day +100: 0. Conclusion. Autologous stem cell transplantation is safe and recommended option for treatment ofpatients with autoimmune disease and hematologic neoplasm.
