Introduction: Adult-onset Still Disease (AoSD) is a rare systemic polygenic nonfamilial autoinflammatory disease of unknown aetiology. The long-term course of the disease can be categorised in three different definitions including self-limited course, intermittent course or chronic course. Recently, Neutrophil-to-Lymphocyte Ratio (NLR) and Platelet-to-Lymphocyte Ratio (PLR) were investigated in various rheumatic diseases as an informative markers in evaluating severity of inflammation and disease activity. Aim: To explore association between baseline NLR, PLR, disease activity score and subsequent disease course in patients with AoSD. Materials and Methods: This retrospective cohort study enrolled 61 patients with AoSD and 61 age-matched patients with Fibromyalgia Syndrome (FMS). Pouchot score was specifically used in AoSD patients to assess disease activity based on symptoms, physical examination findings and laboratory results from April 2020 to July 2020. Patients with AoSD were subgrouped into three groups: self-limited; intermittent; and chronic course. The association of NLR and PLR with disease activity score was analysed between groups by using independent samples t-test, Mann-Whitney U test and Kruskal Wallis Variance Analysis. Differences between categorical variables were analysed using chi-square test. A p≤0.05 was considered statistically significant. Results: The mean follow-up of the 61 patients with AoSD was 74 months (range, 14-169). Eighteen patients (29.5%) had a self-limited disease course, nine (14.8%) an intermittent disease course and thirty four (55.7%) a chronic disease course. AoSD patients had significantly higher serum NLR, PLR and lower Mean Platelet Volume (MPV) values than FMS patients {6.68 (1.67-19.7), 1.83 (1.1-4) p=0.0001; 187 (82.9-549), 114 (72-246) p=0.0001; 8.3 (6.4-11.3), 9.3 (7.7-11.7) p=0.0001, respectively}. NLR, PLR and Pouchot score were similar among AoSD subgroups, which were grouped according to disease pattern. The majority of patients in the self-limited and chronic course groups had higher baseline Pouchot score without statistical significance. The NLR and C-Reactive Protein (CRP) were significantly higher in AoSD patients with active disease than inactive disease {7.02 (1.8-19.7), 4.17 (1.67-14.8) p=0.06; 13 (1.9-29.5), 9 (1.6-20.9) p=0.046, respectively)}. Conclusion: High NLR and elevated CRP levels are related to active disease in AoSD patients. Although NLR, PLR and Pouchot score were similar among subgroups, patients with a chronic course or self-limited course had higher NLR values and more active disease at diagnosis compared with patients with an intermittent course.

Abstract Objectives Triggering receptor expressed on myeloid cells-1 (TREM-1) is an amplifier of inflammatory signals. Recently, a soluble form of TREM-1 (sTREM-1) was described. This study aimed to investigate the role of serum sTREM-1 in patients with adult-onset Still’s disease (AOSD). Methods Serum sTREM-1 levels were detected in 108 AOSD patients, 88 RA patients and 112 healthy controls (HC). The correlations of sTREM-1 with disease activity, clinical characteristics and laboratory parameters in AOSD patients were analysed by the Spearman correlation test. Risk factors for the chronic course of AOSD were evaluated by multivariate logistic regression analysis. Results AOSD patients had significantly higher serum sTREM-1 levels than RA patients and HC, and serum sTREM-1 levels were correlated with the systemic score, ferritin, leucocyte count, CRP, IL-1β and IL-6. The elevation in the initial sTREM-1 level by itself could discriminate patients developing the chronic course from patients developing the nonchronic course. Moreover, an elevated sTREM-1 level (> 526.4475 pg/ml) was an independent risk factor for the chronic course in active AOSD patients. Furthermore, interfering with TREM-1 engagement led to reductions in the secretion of pro-inflammatory cytokines, such as IL-1β, IL-6 and TNF-α, in neutrophils and monocytes from active AOSD patients. Conclusion Serum sTREM-1 levels are correlated with disease activity, and an elevation in the initial serum sTREM-1 level is a potential predictor of the chronic course in AOSD patients, which currently provides the best predictive model for identifying patients prone to developing the chronic course of AOSD.

Objective.The dysregulation of the NLRP3 (NLR containing a pyrin domain) inflammasome is involved in autoinflammatory diseases. Adult-onset Still disease (AOSD) is regarded as an autoinflammatory disease. However, the pathogenic involvement of NLRP3 inflammasome in AOSD remains unclear and NLRP3 activators in AOSD are currently unknown.Methods.The mRNA expression of NLRP3 inflammasome signaling in peripheral blood mononuclear cells (PBMC) from 34 patients with AOSD and 14 healthy subjects was determined using quantitative-PCR (qPCR). The changes in mRNA and protein levels of NLRP3 inflammasome signaling in PBMC treated with the potential activator [imiquimod (IMQ)] or inhibitor of NLRP3 were evaluated using qPCR and immunoblotting, respectively. The supernatant levels of interleukin (IL)-1β and IL-18 were determined by ELISA.Results.Significantly higher mRNA levels of NLRP3 inflammasome signaling were observed in patients with AOSD compared with healthy controls. NLRP3 expressions were positively correlated with disease activity in patients with AOSD. IMQ (an effective Toll-like receptor 7 ligand; 10 µg/ml and 25 µg/ml) stimulation of PBMC from patients with AOSD induced dose-dependent increases of mRNA expression of NLRP3 (mean ± standard error of the mean, 2.06 ± 0.46 and 6.05 ± 1.84, respectively), caspase-1 (1.81 ± 0.23 and 4.25 ± 0.48), IL-1β (5.68 ± 1.51 and 12.13 ± 3.71), and IL-18 (2.32 ± 0.37 and 4.81 ± 0.51) compared with controls (all p < 0.005). IMQ stimulation of PBMC from patients similarly induced greater increases in protein expressions of NLRP3 inflammasome compared with controls. The protein expressions of NLRP3, IL-1β, and IL-18 on PBMC significantly decreased after treatment with NLRP3 inhibitor in patients with AOSD.Conclusion.Increased expression of NLRP3 inflammasome and its positive correlation with disease activity in AOSD suggest its involvement in disease pathogenesis. IMQ upregulated expressions of NLRP3 inflammasome signaling, and IMQ might be an activator of NLRP3 inflammasome in AOSD.
