Objective.Interleukin 18 (IL-18) has a central role in the pathogenesis of adult-onset Still’s disease (AOSD). We investigated the functional association of −607 (C/A) IL-18 promoter polymorphisms with disease course in Chinese patients with AOSD.Methods.Sequence-specific primer polymerase chain reaction and the restriction fragment-length polymorphism method were used to analyze the genotypes of IL-18 promoter polymorphism at position −607 in 96 unrelated patients with AOSD and 164 ethnically-matched healthy controls. Serum IL-18 levels were determined using ELISA in patients with active untreated AOSD.Results.Significantly lower frequencies of single-nucleotide polymorphism −607/AA were observed in patients with AOSD compared to healthy controls (18.8% vs 31.1%, respectively; p < 0.05). Median levels of serum IL-18 were significantly lower in AOSD patients with AA genotype compared to those with CA genotype or CC genotype (147.5 pg/ml vs 410.5 pg/ml or 262.4 pg/ml, respectively; both p < 0.05). Significantly lower IL-18 levels were demonstrated in AOSD patients with a monocyclic systemic course than in those with a polycyclic systemic course or a chronic articular course. The AA genotype was more frequently observed in patients with monocyclic systemic course, which had the best prognosis, than in those with the other 2 disease courses. In contrast, a lower frequency of the AA genotype than the CA or the CC genotype was observed in patients with chronic disabling arthritis (5.5% vs 25.0% or 19.2%, respectively).Conclusion.The SNP −607/AA genotype with lower IL-18 levels might be a genetically protective factor for the occurrence of AOSD in the Chinese population, against progression of chronic disabling arthritis.

Objective.To describe the onset, clinical features, prognostic factors, and treatment of adult-onset Still’s disease (AOSD) in cases from China.Methods.Sixty-one Chinese patients with AOSD were analyzed retrospectively.Results.Common clinical features were fever (100.0%), rash (88.5%), and arthritis (82.0%). The laboratory findings were as follows: leukocytosis (83.6%), increased erythrocyte sedimentation rate (100.0%), elevated transaminase concentrations (23.0%), elevated ferritin levels (79.6%), negative antinuclear antibody (88.5%), and negative rheumatoid factor (88.5%). Of the 61 patients, 44.3% exhibited a monocyclic disease pattern, 29.5% experienced disease relapse at least once, 16.4% exhibited chronic articular course, and 9.8% died; most deaths were due to pulmonary infection and respiratory failure. Based on the disease course, we divided the 61 patients into 2 groups: those with favorable outcome (cyclic disease course, n = 45) and unfavorable outcome (chronic disease course or death, n = 16). We analyzed the prognostic factors for the 2 groups, and found that pleuritis, interstitial pneumonia, elevated ferritin levels, and failure of fever to subside after 3 days of prednisolone at 1 mg/kg/day were unfavorable prognostic factors for patients with AOSD.Conclusion.Patients with AOSD had complex symptoms with no specific laboratory findings. Our results indicate that AOSD is not a relatively benign disease, especially in cases that are refractory to high doses of prednisone.

Interleukin 18 (IL-18) is a pro-inflammatory cytokine of the IL-1 family, whose activity is tightly controlled at the level of production, as well as signalization. Notably, it is buffered by its natural inhibitor, IL-18 binding protein (IL-18BP), which is massively present in circulation in normal and in most pathological conditions, thus preventing harmful pro-inflammatory systemic effects of IL-18. IL-18 has long been considered to be involved in the pathophysiology of various inflammatory diseases. However, a first clinical trial using recombinant IL-18BP for the treatment of rheumatoid arthritis and psoriasis gave disappointing results. Direct measurements of unbound, bioactive, free form of circulating IL-18 demonstrated that IL-18 was more specifically involved in adult-onset Still’s disease (AOSD) and systemic juvenile idiopathic arthritis (sJIA) but also in their most severe complication, macrophage activation syndrome (MAS). More importantly, administration of recombinant IL-18BP to patients with AOSD, and sJIA with MAS, showed promising results. This review summarizes available data regarding IL-18 and IL-18BP in AOSD and sJIA in mouse models and humans and shows the importance of IL-18/IL-18BP imbalance in these conditions, leading to the conclusion that IL-18, particularly free IL-18, may be a useful biomarker in these diseases and an interesting therapeutic target.

Objective.Fcγreceptors (FcγR) have important functions in the regulation of immune response and clearance of immune complex. High levels of immunoglobulins have been observed in patients with the active stage of adult onset Still’s disease (AOSD), and high-dose intravenous immunoglobulin treatment has decreased the disease activity of AOSD. We investigated polymorphisms of FcγR as genetic factors influencing susceptibility or disease course of AOSD in Korea.Methods.We genotyped the FcγRIIA H/R131, IIIA F/V176, and IIIB NA1/NA2 loci in 98 patients with AOSD and 151 healthy controls. Genotyping was performed using sequence-specific PCR. Patients with AOSD were subdivided into groups according to disease course: monocyclic systemic, polycyclic systemic, or chronic articular type. Allelic, genotypic, and haplotypic associations were analyzed by chi-square test.Results.No significant skewing in any of the 3 FcγR polymorphisms was found between Korean AOSD patients and controls. FcγRIIA R/R131 and R/H131 genotype in patients with chronic articular-type disease was more frequent than in controls (p = 0.006 and pcorr = 0.018). No differences of genotypic and allelic frequencies were found between other disease course types and controls. Haplotype IIA R131-IIIA F176-IIIB NA2 was more frequent in AOSD patients than in controls (p = 0.021).Conclusion.Although FcγR polymorphisms are not associated with development of AOSD in Koreans, the haplotype IIA R131-IIIA F176-IIIB NA2 may be associated with AOSD. Also, the FcγRIIA polymorphism may be associated with chronic articular-type AOSD. We need to identify whether these polymorphisms are associated with a response to anti-tumor necrosis factor agents in patients with AOSD.

Objective.S100A8/A9, follistatin-like protein 1, and interleukin 18 (IL-18) have been suggested as biomarkers of disease activity in patients with systemic juvenile idiopathic arthritis or adult-onset Still’s disease (AOSD). We investigated the clinical significance of these factors in AOSD.Methods.Blood samples were collected from 36 patients with AOSD, 40 patients with rheumatoid arthritis (RA), and 33 healthy controls. Of the patients with AOSD, followup samples were collected from 16 patients after resolution of disease activity.Results.Serum levels of S100A8/A9 (11.77 ± 8.84 μg/ml) in AOSD patients were higher than those in RA patients (3.53 ± 3.43 μg/ml; p < 0.001) and controls (2.49 ± 1.83 μg/ml; p < 0.001). Follistatin-like protein 1 levels in AOSD were not different from those in RA and controls. IL-18 levels in AOSD (7560.3 ± 7577.6 pg/ml) were higher than those in RA (217.7 ± 292.1 pg/ml; p < 0.001) and controls (139.2 ± 86.2 pg/ml; p < 0.001). The sensitivity and specificity of IL-18 for diagnosing AOSD was highest with a cutoff value of 366.1 pg/ml. Serum S100A8/A9 correlated with leukocyte count, erythrocyte sedimentation rate, C-reactive protein, ferritin, and systemic disease score; however, IL-18 correlated only with ferritin and systemic disease score. S100A8/A9 was decreased after disease activity was resolved in followup of AOSD patients (9.96 ± 7.35 μg/ml in active AOSD vs 3.6 ± 4.77 μg/ml in resolved cases; p = 0.001). The change of S100A8/A9 was well correlated with that of systemic disease score.Conclusion.The data suggest that serum S100A8/A9 may be a useful biomarker for evaluating disease activity in patients with AOSD.

Abstract Objective Liver damage is a common manifestation and can be life-threatening in adult-onset Still’s disease (AOSD), an autoinflammatory disease. The hallmark of AOSD is activation of neutrophils, whose infiltration in liver is suspected to promote tissue injury. Here we aimed to identify a candidate biomarker and to validate its association with liver damage in AOSD. Methods Transcriptome analysis of neutrophils from treatment-naïve active AOSD patients and healthy donors was performed. Lipocalin-2 (LCN2) expression was assessed in neutrophils, plasma and liver biopsies of AOSD. The correlations of LCN2 with different variables and its ability to identify liver damage from AOSD patients were analysed. Results LCN2, a novel biomarker in hepatic inflammation, was found to be upregulated in AOSD neutrophils by RNA sequencing and confirmed at the mRNA and protein levels. Plasma levels of LCN2 were significantly higher in AOSD patients than healthy controls, RA and SLE patients. Plasma LCN2 levels were closely correlated with inflammatory markers, systemic score, HScore and cytokines. Moreover, LCN2 levels were increased in active AOSD with liver involvement and independently associated with liver dysfunction. Enhanced expression of LCN2 was detected in liver biopsies from three patients with ongoing liver injury. Furthermore, the area under the curve value of LCN2 for identifying AOSD with liver injury from other liver diseases was 0.9694. Conclusion Our results reveal that neutrophils-derived LCN2 is higher in plasma and liver tissue in AOSD patients than in healthy controls, and it could serve as a potent biomarker for identifying AOSD with systemic inflammation, especially liver damage caused by hyperinflammation.
