Toll-like receptor 4 (TLR4), the first line of defence in the innate immune system, has been linked to the pathogenesis of autoimmune diseases and LN by activating nuclear factor-κB (NF-κB) or interferon regulatory transcription factor 3 (IRF3). Local expression of those biomarkers in pristane-induced lupus mice is still unknown. Therefore, this study aimed to prove the role of TLR4, NF-κB and IRF3 in pristane-induced lupus mice.</p><p><strong>Subjects and methods: </strong>The study subjects were female Balb/c pristane-induced lupus mice model, 8-12 weeks of age, n=30, divided into two groups, nephritis (LN group) and non-nephritis (SLE group). The control group were age-matched healthy female Balb/c mice, n=11. All mice were euthanised at weeks 16. Kidney tissue was taken for histopathology examination and TLR4, NF-κB, IRF3 immunofluorescence assay. The diagnosis of LN was based on proteinuria and histopathology examination according to the ISN/RPS 2004 classification of LN. Statistical analysis was performed using IBM SPSS Statistics V.25. P value <0.05 was considered statistically significant.</p><p><strong>Results: </strong>There were significant differences in the expressions of TLR4, NF-κB and IRF3 among the LN, SLE and healthy control groups (p=0.000), with the highest expression found in the LN group for all markers. The linear regression between TLR4 and NF-κB resulted in p value=0.000; R<sup>2</sup>=0.817; β=0.904. Linear regression between TLR4 and IRF3 showed p value=0.000; R<sup>2</sup>=0.896; β=0.947, which means TLR4 had an 81.7% effect on NF-κB and 89.6% on IRF3 expression.</p><p><strong>Conclusion: </strong>TLR4, NF-κB and IRF3 expression were increased in lupus, with the highest expression found in the LN group, suggesting that these biomarkers may be responsible for the development of nephritis in SLE, with TLR4 likely playing a dominant role in this pathway. Increased expression of these biomarkers in lupus without nephritis may indicate progression towards nephritis, which still needs to be proven with further research.</p>","PeriodicalId":18126,"journal":{"name":"Lupus Science & Medicine","volume":"12 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143811743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only observational or experimental studies focusing on extrarenal manifestations in adult patients with SLE in Saudi Arabia were included. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist for systematic reviews to ensure a rigorous and comprehensive evaluation.</p><p><strong>Results: </strong>A total of 35 studies were included, primarily retrospective cohort studies. Riyadh showed the highest number of publications over time. Musculoskeletal involvement in SLE ranged from 2% to 100%, with most studies reporting 46%-85%. Mucocutaneous manifestations, including discoid rash (5%-100%), malar rash (up to 79%) and photosensitivity (6.12%-29.3%), varied widely. Raynaud's phenomenon was noted at 4.5%-15.2%. Constitutional symptoms were more common in early-onset SLE, while serositis and cardiopulmonary issues showed variability. Neuropsychiatric symptoms, especially depression, reached up to 67.6%.</p><p><strong>Conclusion: </strong>This study explores the prevalence of extrarenal manifestations of SLE among adult Saudi patients, highlighting significant regional variability in musculoskeletal, dermatological, cardiovascular and neurological symptoms. It addresses a gap in the literature for a region where autoimmune diseases are a growing public health concern. The findings emphasise the need for population-based studies to investigate environmental, genetic and lifestyle factors influencing SLE progression.</p>","PeriodicalId":18126,"journal":{"name":"Lupus Science & Medicine","volume":"12 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11883561/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143567207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
