The aim of this study was to investigate whether osteopontin(OPN)variants are associated with susceptibility to ankylosing spondylitis (AS) in a Chinese population. Polymorphisms at the 9175th position in exon 7 ofOPNand rs17524488 were genotyped using direct sequencing in 186 unrelated AS patients and 188 ethnically matched healthy controls. Serum concentration of OPN was measured by enzyme-linked immunosorbent assay (ELISA) in all participants. AS patients displayed significantly higher OPN serum levels than the controls (P<001). A heterozygous, novel 9175 T>A in exon 7 of theOPNgene was found in this study. In healthy controls, subjects carrying the rs17524488 G/G genotype of theOPNdisplay significantly higher OPN serum levels than the GG/GG genotype (P<0.05). Plasma OPN level is implicated as an early diagnostic marker of AS. The novel 9175th- (exon 7) position polymorphism ofOPNand rs17524488 were related to susceptibility to AS in a Chinese population, the rs17524488 G/G genotype may be involved in the pathogenesis of AS, and the precise molecular mechanism underlying the influence ofOPNpolymorphisms on the development of AS remains to be determined in the further prospective studies.

Objective: Genetic polymorphisms of the Interleukin-10 (IL-10) promoter have been implicated in several autoimmune diseases, including seronegative spondyloarthropathies. This study investigated whether single nucleotide polymorphisms (SNPs) and haplotypes of IL-10 are associated with ankylosing spondylitis (AS), a common subtype of spondyloarthritis (SpA). Methods: The serum levels of IL-10 were measured with an enzyme-linked immunosorbent assay (ELISA). The single nucleotide polymorphisms (SNPs) at positions -1082A/G, -819C/T and -592C/A in the IL-10 gene promoter were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: 110 AS patients and 120 ethnic-matched healthy controls were included in this study. The serum levels of IL-10 were significantly higher in AS patients than healthy controls (Z=-10.9, P < 0.001). Single SNP analysis showed no significant differences in the allelic and genotypic frequencies of -592A/C between the AS patients and healthy controls. No -1082GG genotype was found in this study. An increased frequency of -1082G allele was noted in AS patients (P=0.047). In a logistic regression analysis, the -1082AG genotype was associated with an odds ratio of 1.993 (95%CI, 1.046-3.800, P=0.034) for AS. And the -819CC genotype was associated with an odds ratio of 3.125 (95%CI, 1.246-7.836, P=0.015) for AS. Furthermore, haplotype analysis revealed that GCC haplotype was associated with a significantly increased risk of AS as compared with the ATA haplotype (OR=2.19; 95% CI, 1.13-4.26; P=0.02). Conclusion: Our results indicate that the gene haplotype of IL-10 can contribute to the susceptibility to AS in a Chinese population.

Abstract Objective. It was previously demonstrated that cutaneous vasculitis, including IgA vasculitis and cutaneous arteritis (CA), is associated with the presence of IgM antibodies (Abs) against the phosphatidylserine/prothrombin complex (PS/PT). Recently, novel enzyme-linked immunosorbent assay kits for the detection of IgG and IgM anti-PS/PT (aPS/PT) Abs have become commercially available.Methods. The prevalence of serum IgG and IgM aPS/PT Abs in both cutaneous and systemic vasculitis was determined using these kits. In addition, to examine whether aPS/PT Abs were involved in the pathogenesis of cutaneous vasculitis, inbred wild-type rats were intravenously administered with a rat IgM class aPS/PT monoclonal Ab established previously or with rat immunoglobulins as controls. To express PS on the surface of vascular endothelium, these rats were given a subcutaneous injection of cell-free histones (250 µg/ml, 300 µl/site) 2 hours in advance. Results. Serum IgM aPS/PT Ab levels were elevated in patients with systemic vasculitis with skin involvement and CA compared to those in patients with systemic vasculitis without skin involvement and healthy controls. There was no significant difference in the serum levels of IgG aPS/PT Abs between the patients and healthy controls. Correspondingly, inbred wild-type rats intravenously administered with the aPS/PT monoclonal IgM Ab after appropriate priming—subcutaneous histone injection—developed cutaneous vasculitis. Some rats given rat IgM instead of the aPS/PT monoclonal Ab also developed cutaneous vasculitis, whereas vasculitis did not occur in rats given IgG or only priming by histones. Conclusion. IgM aPS/PT Abs could be involved in the pathogenesis of cutaneous vasculitis.

SummaryImmune dysfunction has been proposed as a mechanism for the pathophysiology of autistic-spectrum disorders. The selectin family of adhesion molecules plays a prominent role in immune/inflammatory responses. We determined the serum levels of three types of soluble-form selectin (sP, sL and sE) in 15 men with high-functioning autism and 22 age-matched healthy controls by enzyme-linked immunosorbent assay. Levels of sP-selectin and sL-selectin were significantly lower in patients than in controls. Furthermore, sP-selectin levels were negatively correlated with impaired social development during early childhood.

Objective. IgA vasculitis (lgAV) is the most frequent vessel vasculitis in children, and the prognosis is related to the children’s age and degree of nephritis. This study is aimed at investigating serum apolipoprotein M (apoM) levels in patients with lgAV patients and at evaluating the association between apoM and disease severity. Methods. A total of 109 lgAV patients and 76 age- and sex-matched healthy controls were included. The age and gender of the study participants were matched. ApoM levels were measured by an enzyme-linked immunosorbent assay. Additionally, the serum levels of lipids, apolipoproteins, kidney biochemical profiles, immunoglobulins (IgA, IgG, IgM, and IgE), and the complements (C3 and C4) were assessed using an automatic biochemical analyzer. Results. ApoM was increased significantly in lgAV patients compared to healthy controls. ApoM, meanwhile, was lower in patients with nephritis than in those without nephritis. The apoM levels were higher in classes I and II IgA vasculitis nephritis (lgAVN) patients than in classes III and IV. Besides, the apoM serum level<24.81 mg/L was an independent predictive factor for lgAVN and can be independently associated with the presence of nephritis in lgAV patients. Meanwhile, the serum apoM concentration negatively correlated with the ISKDC grading score in lgAVN patients. Conclusions. Serum apoM was elevated in lgAV patients and decreased gradually with the ISKDC grading score. ApoM (OR=0.32, 95%CI=0.12‐0.85, p=0.023) was identified as a protective factor for nephritis in all lgAV patients.

Fibroblast growth factor 21 (FGF-21) is known to be a biomarker for mitochondrial disorders. An upregulation of FGF-21 in serum and muscle of carnitine palmitoyltransferase I (CPT I) and carnitine palmitoyltransferase II (CPT II) knock-out mice has been reported. In human CPT II deficiency, enzyme activity and protein content are normal, but the enzyme is abnormally regulated by malonyl-CoA and is abnormally thermolabile. Citrate synthase (CS) activity is increased in patients with CPT II deficiency. This may indicate a compensatory response to an impaired function of CPT II. In this study, FGF-21 serum levels in patients with CPT II deficiency during attack free intervals and in healthy controls were measured by enzyme linked immunosorbent assay (ELISA). The data showed no significant difference between FGF-21 concentration in the serum of patients with CPT II deficiency and that in the healthy controls. The results of the present work support the hypothesis that in muscle CPT II deficiency, in contrast to the mouse knockout model, mitochondrial fatty acid utilization is not persistently reduced. Thus, FGF-21 does not seem to be a useful biomarker in the diagnosis of CPT II deficiency.

Abstract Aim Chronic alcohol consumption can activate and dysregulate the neuroimmune system which leads to neuroinflammation. Neuroimmune regulatory proteins (NIReg) (e.g. Cluster of Differentiation 200 (CD200)) are the regulators of innate immune response and are responsible for silencing the innate immunity and suppression of inflammation. In this study, we explored the changes of serum levels of CD200 in patients with alcohol dependence at baseline, after one-week alcohol withdrawal and after one-month of alcohol abstinence. Methods Seventeen patients with alcohol dependence admitted for de-addiction treatment and 12 healthy controls were enrolled in the study. Blood samples were collected at baseline, after one-week, and after one-month, and CD200 levels were measured using enzyme-linked immunosorbent assay kit and compared with the healthy controls. Results The serum level of the neuroimmune regulatory protein CD200 in alcohol dependent group (at baseline) was significantly lower compared to healthy controls (p=0.003), and increased after one-week, and one-month period. Conclusion The present study indicates that decrease of CD200 serum levels in alcohol dependent patients and its rise during alcohol withdrawal and abstinence may provide a preliminary evidence of the role of neuroimmune regulatory proteins in neuroadaptation during alcohol withdrawal.

The role of C-reactive protein (CRP) in systemic lupus erythematosus (SLE) as an inflammatory marker is still controversial. Recently, more sensitive methods, such as high sensitive CRP (hs-CRP) have been used to detect micro-inflammation. The role of hs-CRP in lupus flare has not been documented well. We conducted this study to examine the correlation between hs-CRP serum concentrations and disease activity in lupus. Ninety-two SLE patients and 49 healthy controls contributed to our study. Most confounding factors influencing the hs-CRP values were excluded. Disease activity was estimated using the SLE Disease Activity Index (SLEDAI-2K). hs-CRP values were determined using an enzyme-linked immunosorbent assay (ELISA) kit. Serum values of hs-CRP were significantly higher ( p < 0.001, z = 3.29) in patients compared with healthy controls. The cutoff point for hs-CRP between patients and controls was 0.93 mg/L (Youden’s Index = 0.39). There was no correlation between hs-CRP serum levels and disease activity. Furthermore, hs-CRP values did not correlate with any of the laboratory parameters, except for C3 ( p = 0.003, rs = −0.2) and C4 ( p = 0.02, rs = −0.1). Although hs-CRP serum levels were significantly higher in lupus patients compared with healthy controls, it seems that this marker is not a good indicator for disease activity.

Objective. Programmed cell death 1 (PD-1) induces negative signals to T cells during interaction with its ligands and is therefore a candidate gene in the development of autoimmune diseases such as rheumatoid arthritis (RA). Herein, we investigate the association ofPDCD-1polymorphisms with the risk of RA among Chinese patients and healthy controls.Methods. Using the PCR-direct sequencing analysis, 4PDCD-1SNPs (rs36084323, rs11568821, rs2227982, and rs2227981) were genotyped in 320 RA patients and 309 matched healthy controls. Expression of PD-1 was determined in peripheral blood lymphocytes by flow cytometry and quantitative real-time reverse transcriptase polymerase chain reaction.Results. We observed that the GG genotype of rs36084323 was associated with a increased risk for developing RA (OR 1.70, 95% 1.11–2.61,P=0.049). Patients carrying G/G genotype displayed an increased mRNA level of PD-1(P=0.04)compared with A/A genotype and healthy controls. Meanwhile, patients homozygous for rs36084323 had induced basal PD-1 expression on activated CD4+ T cells.Conclusion. ThePDCD-1polymorphism rs36084323 was significantly associated with RA risk in Han Chinese population. This SNP, which effectively influenced the expression of PD-1, may be a biomarker of early diagnosis of RA and a suitable indicator of utilizing PD-1 inhibitor for treatment of RA.

To determine serum cytokine profiles in Graves’ disease (GD) patients with or without active and inactive thyroid associated ophthalmopathy (TAO), we recruited 65 subjects: 10 GD only (without TAO), 25 GD + active TAO, 20 GD + TAO, and 10 healthy controls. Liquid chip assay was used to measure serum Th1/Th2/Th17 cytokines including IFN-γ(interferon-gamma), TNF-α(tumor necrosis factor-alpha), IL-1α(interleukin-1 alpha), IL-1Ra (IL-1 receptor antagonist), IL-2, IL-4, IL-6, and IL-17 and two chemokines: RANTES (regulated upon activation, normal T cell expressed and secreted) and IP-10 (IFN-γ-induced protein 10). Serum levels of TSH (thyroid stimulating hormone) receptor autoantibodies (TRAb) were measured using an enzyme linked immunosorbent assay. Compared with healthy controls, TAO patients showed significantly elevated serum levels of IFN-γ, TNF-α, IL-1α, IL-4, IL-6, IL-17, and IP-10. Comparing active and inactive TAO, serum Th1 cytokines IFN-γand TNF-αwere elevated in active TAO, while serum Th2 cytokine IL-4 was elevated in inactive TAO. Serum Th17 cytokine IL-17 was elevated in GD but reduced in both active and inactive TAO. A positive correlation was found between TRAb and IFN-γ, TNF-α, IL-1α, IL-2, IL-4, and IL-6. Taken together, serum Th1/Th2/Th17 cytokines and chemokines reflect TAO disease activity and may be implicated in TAO pathogenesis.

Background. Recently, increasing studies have revealed that leptin is involved in the development of rheumatoid arthritis (RA). This study is aimed at exploring the association of leptin gene single nucleotide polymorphisms (SNPs) with susceptibility to RA in a Chinese population. Methods. We recruited 600 RA patients and 600 healthy controls from a Chinese population and analyzed their three leptin SNPs (rs10244329, rs2071045, and rs2167270) using the improved Multiplex Ligase Detection Reaction (iMLDR) assays. The associations of these SNPs with clinical manifestations of RA were also analyzed. Enzyme-linked immunosorbent assay (ELISA) was performed for plasma leptin determination. Results. No significant difference in either allele or genotype frequencies of these three SNPs between RA patients and healthy controls was observed (all P > 0.05 ). Association between the genotype effects of dominant, recessive models was also not found (all P > 0.05 ). No significant difference in plasma leptin levels was detected between RA patients and controls ( P > 0.05 ). Conclusion. Leptin gene (rs10244329, rs2071045, and rs2167270) polymorphisms are not associated with RA genetic susceptibility and its clinical features in the Chinese population.
