Growing evidence suggests that dysregulation of proteins from the sirtuin family, particularly sirtuin-1 (SIRT1), may play a crucial role in the pathophysiology of SLE, despite its incomplete understanding.ObjectiveTo evaluate SIRT1 levels and study potential association with keratoconjunctivitis sicca (KCS) in SLE patients in relation to disease activity.MethodsA cross-sectional study was conducted on 42 SLE adult patients and 42 healthy controls. Serum SIRT1 levels were measured using enzyme-linked immunosorbent assay. Disease activity was assessed using the SLE Disease Activity Index (SLEDAI) score. Correlations between SIRT1 levels, KCS and disease activity, were analyzed.ResultsPatients with SLE had significantly higher SIRT1 levels than healthy controls (<i>p</i> < .001). SIRT1 was strongly correlated with disease activity (r = 0.958, <i>p</i> < .001), and albuminuria (r = 0.719, <i>p</i> < .001). Negative correlations were observed between SIRT1 levels and C3 (r = -0.843, <i>p</i> < .001), C4 (r = -0.861, <i>p</i> < .001), white blood cell count (r = -0.616, <i>p</i> < .001) and platelet count (r = -0.534, <i>p</i> < .001). Additionally, Patients with SLE who presented with KCS had significantly higher SIRT1 levels than those without (<i>p</i> < .001). SIRT1 exhibited exceptional diagnostic efficacy in differentiating between Patients with SLE and control subjects, with an AUC of 1 (<i>p</i> < .001) and in identifying KCS in SLE patients, with an AUC of 0.989 (<i>p</i> < .001). The multivariable regression model indicated that a lower platelets count (<i>p</i> = .034; OR -0.014; 95% CI -0.026 to -0.001) and high SIRT1 levels (<i>p</i> < .001; OR 0.838; 95% CI 0.678-0.998) were independent predictors of disease activity.ConclusionsSerum SIRT1 levels were significantly elevated in patients with SLE and correlated with the presence of KCS and disease activity. SIRT1 may serve as a potential biomarker of eye involvement in SLE, the disease pathogenesis and severity, and its modulation could offer a therapeutic target for the disease.</p>","PeriodicalId":18044,"journal":{"name":"Lupus","volume":" ","pages":"932-942"},"PeriodicalIF":1.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144326185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bayesian analyses have been proposed to implement more flexible pediatric extrapolation approaches in similar situations. Here we discuss a post-hoc Bayesian analysis the FDA employed which borrowed information from the phase 3 IV belimumab studies in adults to supplement the efficacy information collected in the pediatric population.MethodsWe used a Bayesian method to estimate the treatment effect in SLE Responder Index (SRI) response in pediatric patients, with a robust mixture prior that was a weighted combination of a skeptical prior that assumed no treatment effect and a meta-analysis of the treatment effects seen in adults. The weighting was based on the degree of belief in the similarity of the disease and treatment effect between pediatric and adult subjects.ResultsThe trial design and conduct, endpoints, key demographic and disease characteristics as well as pharmacokinetics (PK) were similar between the pediatric and adult study populations, which justified borrowing information from across studies. A prior weight of 55% or larger on the adult data provided 95% credible intervals that excluded an odds ratio of one, providing supportive evidence that belimumab is an effective treatment in pediatric patients. These results were further supported by the secondary efficacy endpoints, PK and safety.ConclusionThis approach contributed to FDA's decision to approve belimumab as the first treatment for cSLE.
