Abstract
Objective The objective of this analysis was to explore associations between paraoxonase-1 levels, gene polymorphisms and systemic lupus erythematosus. Methods Meta-analyses of paraoxonase-1 levels and Q192R and L55M and polymorphisms in systemic lupus erythematosus were conducted. Results Nine articles were incorporated in our meta-analysis, which uncovered that the paraoxonase-1 level was decreased in systemic lupus erythematosus compared to control (standard mean difference = −1.626, 95% confidence interval = −2.829–−0.424, p = 0.008). Ethnicity-specific meta-analysis demonstrated a relation tendency between decreased paraoxonase-1 activity and lupus in Europeans (standard mean difference = −1.236, 95% confidence interval = −2.634–0.163, p = 0.083). Paraoxonase-1 activity was reduced in systemic lupus erythematosus in a single Arab and African population. Decreased paraoxonase-1 activity was found in a small sample of systemic lupus erythematosus patients (standard mean difference = −1.642, 95% confidence interval = −3.076–−0.247, p = 0.021). Ethnicity-specific analysis indicated a relationship between the paraoxonase-1 55 M allele in the Arab systemic lupus erythematosus population. However, a lack of association with systemic lupus erythematosus and the paraoxonase-1 192 R allele was observed. Conclusions Meta-analyses revealed reduced paraoxonase-1 activity in patients with systemic lupus erythematosus and found possible associations between systemic lupus erythematosus and paraoxonase-1 L55M polymorphism in a specific ethnic group.

Abstract
BACKGROUND AND PURPOSE Subcortical structures are affected by neurodegeneration in Alzheimer's disease (AD) and Lewy body disease (LBD). Although the co-occurrence of AD and LBD pathologies and their possible interaction have been reported, the effect of AD and LBD on subcortical structures remains unknown. The effects of AD and LBD on subcortical atrophy and their relationship with cognitive dysfunction were investigated. METHODS The cross-sectional study recruited 42 patients with pure AD related cognitive impairment (ADCI), 30 patients with pure LBD related cognitive impairment (LBCI), 58 patients with mixed ADCI and LBCI, and 29 normal subjects. A general linear model was used to compare subcortical volume and shape amongst the groups, to investigate the independent and interaction effects of ADCI and LBCI on subcortical shape and volume, and to analyze the relationship between subcortical volume and cognitive dysfunction in each group. RESULTS Alzheimer's disease related cognitive impairment and LBCI were independently associated with subcortical atrophies in the hippocampus and amygdala and in the hippocampus and putamen respectively, but their interaction effect was not significant. Compared to the control group, the pure LBCI group exhibited additional local atrophies in the amygdala, caudate and thalamus. Subcortical atrophies correlated differently with cognitive dysfunction according to the underlying causes of cognitive dysfunction. CONCLUSIONS The patterns of subcortical atrophies and their correlation with cognitive dysfunction differ according to the underlying AD, LBD or concomitant AD and LBD.

Abstract
OBJECTIVE To examine whether alcohol intake is causally associated with rheumatoid arthritis (RA). METHODS We performed a two-sample Mendelian randomization (MR) analysis using the inverse-variance weighted (IVW), weighted median, and MR-Egger regression methods. We used the publicly available summary statistics of alcohol intake frequency from the UK Biobank genome-wide association studies (GWASs; n = 336,965) as the exposure and a GWAS meta-analysis of 5539 autoantibody-positive RA patients and 20,169 controls as the outcome. RESULTS We selected 24 single nucleotide polymorphisms (SNPs) associated with alcohol intake frequency at genome-wide significance as instrumental variables (IVs) to improve inference, 16 of which were inversely associated with RA. The IVW method showed no evidence of a causal association between alcohol intake and RA (beta = 0.218, SE = 0.213, p = 0.306). The MR-Egger regression revealed that directional pleiotropy was unlikely to bias the result (intercept = 0.027, p = 0.292). The MR-Egger analysis and the weighted median approach showed no causal association between alcohol intake and RA (beta = -0.778, SE = 0.947, p = 0.420 and beta = -0.286, SE = 0.302, p = 0.344, respectively). Cochran's Q test did not indicate heterogeneity between IV estimates based on the individual variants, and results from a "leave-one-out" analysis demonstrated that no single SNP was driving the IVW point estimate. CONCLUSION The MR analysis does not support a causal inverse association between alcohol intake and RA occurrence.

Abstract
OBJECTIVES The relative efficacy and safety of tofacitinib and baricitinib were assessed in patients with rheumatoid arthritis (RA) with an inadequate response to disease-modifying anti-rheumatic drugs (DMARDs) or biologics. METHODS We performed a Bayesian network meta-analysis to combine direct and indirect evidence from randomized controlled trials (RCTs) to examine the efficacy and safety of tofacitinib and baricitinib in combination with DMARDs in RA patients with an inadequate DMARD or biologic response. RESULTS Twelve RCTs including 5883 patients met the inclusion criteria. There were 15 pairwise comparisons including 10 direct comparisons of 6 interventions. Tofacitinib 10 mg + methotrexate (MTX) and baricitinib 4 mg + MTX were among the most effective treatments for active RA with an inadequate DMARD or biologic response, followed by baricitinib 2 mg + MTX, tofacitinib 5 mg + MTX, and adalimumab + MTX. The ranking probability based on the surface under the cumulative ranking curve (SUCRA) indicated that tofacitinib 10 mg + MTX had the highest probability of being the best treatment to achieve the ACR20 response rate (SUCRA = 0.865), followed by baricitinib 4 mg + MTX (SUCRA = 0.774), baricitinib 2 mg + MTX (SUCRA = 0.552), tofacitinib 5 mg + MTX (SUCRA = 0.512), adalimumab + MTX (SUCRA = 0.297), and placebo + MTX (SUCRA <0.001). No significant differences were observed in the incidence of serious adverse events after treatment with tofacitinib + MTX, baricitinib + MTX, adalimumab + MTX, or placebo + MTX. CONCLUSIONS In RA patients with an inadequate response to DMARDs or biologics, tofacitinib 10 mg + MTX and baricitinib 4 mg + MTX were the most efficacious interventions and were not associated with a significant risk of serious adverse events.

Abstract
OBJECTIVE This study aimed to examine whether rheumatoid arthritis (RA) is causally associated with Alzheimer's disease (AD). METHODS We performed a two-sample Mendelian randomization (MR) analysis using the inverse-variance weighted (IVW), weighted median, and MR-Egger regression methods. We used the publicly available summary statistics datasets from three-stage trans-ethnic genome-wide association studies (GWAS) meta-analyses of 29,880 RA cases and 73,758 controls as exposures and a meta-analysis of 4 GWAS datasets consisting of 17,008 AD cases and 37,154 controls of European descent as outcomes. RESULTS We selected 80 single nucleotide polymorphisms (SNPs) from GWAS data on RA as instrumental variables (IVs), 60 of which were associated with RA on a genome-wide significance level. The IVW method showed evidence to support an inverse causal association between RA and AD (β = -0.039, standard error [SE] = 0.017, P = 0.021). MR-Egger regression revealed that directional pleiotropy was unlikely to be a source of bias in the results (intercept = 0.002; P = 0.649). The MR-Egger analysis showed no causal association between RA and AD (β = -0.050, SE = 0.030, P = 0.096). However, the weighted median approach showed that RA and AD were causally linked (β = -0.078, SE = 0.024, P = 0.001). The funnel plot did not show heterogeneity between IV estimates based on the individual variants. CONCLUSIONS The MR analysis supports that RA was causally associated with a reduced risk of AD.

Abstract
AIMS Many physiological and microbial characteristics influence the biocontrol performance of the biological control agents (BCAs) in agricultural fields. To implement effective biocontrol, the contribution of specific genes, mechanisms and traits to the biocontrol performance of BCAs need to be characterized and explored in greater detail. METHODS AND RESULTS In this study, a transposon (Tn) mutant library using the BCA Pseudomonas fluorescens NBC275 (Pf275) was generated to explore genes and bacterial characteristics involved in antifungal activity and biocontrol performance. Among the Tn mutants, 205 strains showing variations in antifungal activity compared to wild-type (WT) were selected and further analysed for biocontrol efficacy against gray mold in pepper fruits. The genes involved in pyoverdine biosynthesis (pvdI and pvdD) and chitin-binding protein (gbpA) played essential roles in the antifungal activity and biocontrol capacity of Pf275. In addition, a mutation in phlD completely abolished the antifungal activity and significantly suppressed the biocontrol ability of the strain. Genes affecting antifungal activity of Pf275 significantly influenced swimming motility, which was identified as an important trait for the biocontrol ability of the bacterial strain. CONCLUSIONS Overall, our results suggest that antifungal compound production, siderophore biosynthesis and swimming motility synergistically contribute to Pf275 biocontrol performance. The utility of this library was demonstrated by identifying genes for antagonism and biocontrol ability in this BCA strain. The functional roles of many genes identified as contributing to antagonism and in vivo biocontrol activity require further study. SIGNIFICANCE AND IMPACT OF THIS STUDY Genes contributing to antifungal activity and biocontrol performance of P. fluorescens were identified and highlighted by Tn mutagenesis, which will give insight to improve the biocontrol performance of this BCA.

Abstract
Objective The aim of this study was to systematically review evidence regarding the association between CD40 polymorphisms and systemic lupus erythematosus and between soluble CD40 (sCD40) and CD40 ligand (sCD40L) levels and systemic lupus erythematosus. Methods We performed a meta-analysis on the association between CD40 rs4810495, rs1883832, and rs376545 polymorphisms and systemic lupus erythematosus risk and sCD40/sCD40L levels in patients with systemic lupus erythematosus and controls. Results Fourteen studies were included. Ethnicity-specific meta-analysis indicated a significant association between the T allele of CD40 rs4810485 polymorphism and systemic lupus erythematosus in Europeans (odds ratio = 0.715, 95% confidence interval = 0.641–0.832, p < 0.001) and a trend toward an association between the T allele and systemic lupus erythematosus in Asians (odds ratio = 1.255, 95% confidence interval = 0.978–1.810, p = 0.074). Furthermore, a significant association was reported between systemic lupus erythematosus and the C allele of CD40 rs1883832 polymorphism (odds ratio = 1.235, 95% confidence interval = 1.087–1.405, p = 0.001) and A allele of CD40 rs3765456 polymorphism and systemic lupus erythematosus in Asians (odds ratio = 1.184, 95% confidence interval = 1.040–1.348, p = 0.011). sCD40 and sCD40L levels were significantly higher in SLE than in controls (standardized mean difference = 1.564, 95% confidence interval = 0.256–2.872, p = 0.019 and standardized mean difference = 1.499, 95% confidence interval = 1.031–1.967, p < 0.001, respectively). Stratification based on ethnicity revealed higher sCD40L levels in the systemic lupus erythematosus group among European, Asian, North American, and Arab populations. Conclusions Our meta-analyses found associations between CD40 rs4810495, rs1883832, and rs376545 polymorphisms and systemic lupus erythematosus susceptibility and significantly higher sCD40 and sCD40L levels in patients with systemic lupus erythematosus than in controls.

Abstract
OBJECTIVE The aim of this study was to determine the relationship between anti-Porphyromonas gingivalis (anti-P. gingivalis) antibody levels and rheumatoid arthritis (RA) and its correlation with anti-citrullinated protein antibodies (ACPA). METHODS We performed a meta-analysis of studies comparing (a) anti-P. gingivalis antibody levels in RA patients and healthy controls and (b) the correlation coefficients between the anti-P. gingivalis antibody levels and ACPA in RA patients. RESULTS The study included 14 articles with 3829 RA patients and 1239 controls. Our meta-analysis showed that anti-P. gingivalis antibody levels were significantly higher in the RA group than in the control group (standardized mean difference [SMD] = 0.630, 95% CI = 0.272-0.989, p = 0.001). Subgroup analysis revealed that RA patients had significantly elevated anti-P. gingivalis antibody levels compared with healthy controls, but not compared with the non-RA control group and also not between different sample sizes. Anti-P. gingivalis antibody levels were significantly higher in the RA group than in the control group in the age-/sex-matched population, but not in the unmatched population. Anti-P. gingivalis antibody levels were significantly higher in the ACPA-positive group than in the ACPA-negative group (SMD = 0.322, 95% CI = 0.164-0.480, p = 6.4 × 10-5). Meta-analysis of the correlation coefficients showed a significant positive correlation between anti-P. gingivalis antibody levels and ACPA (correlation coefficient = 0.147, 95% CI = 0.033-0.258, p = 0.012). CONCLUSION Our meta-analysis demonstrated that anti-P. gingivalis antibody levels were significantly higher in patients with RA and they were positively correlated with ACPA.

Abstract
OBJECTIVE To assess the relative efficacy and safety of apremilast, secukinumab, and ustekinumab at different doses in patients with active psoriatic arthritis (PsA). METHOD A Bayesian network meta-analysis was conducted, which included randomized controlled trials (RCTs) that examined the efficacy and safety of apremilast 20 mg, apremilast 30 mg, secukinumab 75 mg, secukinumab 150 mg, secukinumab 300 mg, ustekinumab 45 mg, and ustekinumab 90 mg compared with placebo. RESULTS Of the RCTs 8 comprising 3289 patients met the inclusion criteria. The American College of Rheumatology (ACR) 20 response rate was significantly higher in the secukinumab 300 mg group than in the placebo group (odds ratio OR, 7.55; 95% confidence interval CI, 3.18-17.63). Secukinumab 150 mg, secukinumab 75 mg, ustekinumab 90 mg, apremilast 30 mg, apremilast 20 mg, and ustekinumab 45 mg were also more efficacious than placebo. There were no significant differences in the efficacy between the interventions. A dose-response relationship among the same drug groups was observed. The number of serious adverse events was not significantly different among the apremilast, secukinumab, ustekinumab, and placebo groups. CONCLUSION All drug treatments were more efficacious than placebo; however, there were no significant differences in the efficacy and safety between the drugs at the different doses.

Abstract
Phase lag entropy, an electro-encephalography-based hypnotic depth indicator, calculates diversity in temporal patterns of phase relationship. We compared the performance of phase lag entropy with the bispectral index™ in 30 patients scheduled for elective surgery. We initiated a target-controlled infusion of propofol using the Schnider model, and assessed sedation levels using the Modified Observer's Assessment of Alertness/Sedation scale every 30 s with each stepwise increase in the effect-site propofol concentration. Phase lag entropy and bispectral index values were recorded. The correlation coefficient and prediction probability between phase lag entropy or bispectral index and the sedation level or effect-site propofol concentration were analysed. We calculated baseline variabilities of phase lag entropy and bispectral index. In addition, we applied a non-linear mixed-effects model to obtain the pharmacodynamic relationships among the effect-site propofol concentration, phase lag entropy or bispectral index and sedation level. As sedation increased, phase lag entropy and bispectral index both decreased. The prediction probability values of phase lag entropy and bispectral index for sedation levels were 0.697 and 0.700 (p = 0.261) and for the effect-site concentration of propofol were 0.646 and 0.630 (p = 0.091), respectively. Baseline variability in phase lag entropy and bispectral index was 3.3 and 5.7, respectively. The predicted propofol concentrations, using the Schnider pharmacokinetic model, producing a 50% probability of moderate and deep sedation were 1.96 and 3.01 μg.ml-1 , respectively. Phase lag entropy was found to be useful as a hypnotic depth indicator in patients receiving propofol sedation.

Abstract
OBJECTIVE The aim of this study is to determine whether the functional interferon regulatory factor 5 ( IRF5) polymorphism rs2004640 is associated with susceptibility to systemic lupus erythematosus (SLE) in multiple ethnic populations. METHODS A meta-analysis was conducted on the T allele of the IRF5 rs2004640 polymorphism in all study participants as well as each ethnic population. RESULTS Twenty research articles that included 28 comparative studies of 20,892 patients and 24,930 controls were included in the meta-analysis. The Asian population had a much lower prevalence of the T allele than any other study population at 28%, and the European population had the highest prevalence of the T allele at 52%. Meta-analysis showed an association between the IRF5 rs2004640 polymorphism and SLE in all participants (odds ratio = 1.472, 95% confidence interval = 1.370-1.582, p < 0.001). Analysis after stratification by ethnicity indicated that the IRF5 rs2004640 T allele is significantly associated with SLE in Europeans, Asians, Latin Americans and Arabs. CONCLUSIONS This meta-analysis confirms that the IRF5 rs2004640 polymorphism is associated with SLE susceptibility in different ethnic groups, and that its prevalence is ethnicity dependent.

Abstract
OBJECTIVES This study aimed to examine whether alcohol intake is causally associated with systemic lupus erythematosus (SLE). METHODS We performed a two-sample Mendelian randomization (MR) analysis using the inverse-variance weighted (IVW), weighted median, and MR-Egger regression methods. We used the publicly available summary statistics of alcohol intake frequency from the UK Biobank genome-wide association studies (GWASs; n = 336,965) as the exposure and an SLE GWAS consisting of 1311 SLE and 1783 control subjects of European descent as the outcome. RESULTS We selected 20 single nucleotide polymorphisms (SNPs) associated with alcohol intake frequency at genome-wide significance as instrumental variables to improve inference. The IVW method found no evidence to support a causal association between alcohol intake and SLE (beta = -0.413, SE = 0.513, p = 0.421). The MR-Egger regression revealed that directional pleiotropy was unlikely to bias the result (intercept = 0.031, p = 0.582). The MR-Egger analysis found no causal association between alcohol intake and SLE (beta = -1.494, SE = 1.996, p = 0.464). Likewise, the weighted median approach also did not provide evidence of a causal association between alcohol intake and SLE (beta = -0.538, SE = 0.574, p = 0.349). The MR estimates determined using the IVW, weighted median, and MR-Egger regression methods were consistent and results from a "leave-one-out" analysis demonstrated that no single SNP was driving the IVW point estimate. CONCLUSIONS The results of MR analysis do not support a causal inverse association between alcohol intake and SLE occurrence.

Abstract
BACKGROUND Vitamin D is considered a regulator of the immune system, and its polymorphisms have been associated with psoriasis in some but not all reports. AIM To explore whether vitamin D receptor (VDR) polymorphisms are associated with susceptibility to psoriasis. METHODS Meta-analyses were conducted to determine the associations between psoriasis and the VDR ApaI, TaqI, BsmI and FokI polymorphisms in all participants, and stratified by ethnic group. RESULTS In total, 16 studies on VDR polymorphisms and psoriasis were included in this meta-analysis, which involved 2086 patients and 2182 controls. The meta-analysis indicated an association between psoriasis and the VDR TaqI TT genotype in Caucasian (OR = 1.29, 95% CI = 1.00-1.66, P < 0.05), but not in Asian (OR = 1.32, 95% CI = 0.89-1.96, P = 0.16) populations. However, no association was found between psoriasis and the VDR TaqI polymorphism using dominant, allele contrast or homozygous contrast models. No association was found between psoriasis and either the VDR ApaI, BsmI or FokI polymorphisms by meta-analyses of the allele contrast, recessive, or dominant models or homozygous contrast models in the overall, Caucasian or Asian populations. CONCLUSION This meta-analysis showed that polymorphisms in VDR ApaI, BsmI and FokI are not associated with psoriasis susceptibility in overall, Caucasian or Asian populations. However, the VDR TaqI polymorphism is associated with psoriasis susceptibility in Caucasian populations.

Abstract
Two series of experiments were performed to investigate the aerobic preservation of fruit and vegetable discards (FVD) using sodium metabisulfite (SMB). In Exp. 1, metabisulfite was applied at 0, 2, 4, 6, and 8 g/kg FVD for 0, 3, 6, 9, and 12 d. Metabisulfite treatment at 6 and 8 g/kg FVD was highly effective in controlling putrefaction and preserving the nutrient components for 6 and 9 d, respectively. In the pilot-scale experiment (Exp. 2), SMB was applied at 0 and 8 g/kg FVD in a 600-L bucket for 0, 6, and 9 d in an outdoor environment. The SMB treatment was highly effective in maintaining the integrity and freshness of FVD, suppressing microbial proliferation, and preserving the nutrient constituents. Under the conditions of this study, SMB effectively preserved FVD in an aerobic environment, enabling their more efficient long-term recycling through livestock feed or development of value-added products.

Abstract
Although surrogate measures to quantify pain intensity have been commercialised, there is a need to develop a new index with improved accuracy. The aim of this study was to develop a new analgesic index using nasal photoplethysmography data. The specially designed sensor was placed between the columella and the nasal septum to acquire nasal photoplethysmography in surgical patients. Nasal photoplethysmography and Surgical Pleth Index® (GE Healthcare) data were obtained for 14 min both in the absence (pre-operatively) or presence (postoperatively) of pain in a group of surgical patients, each patient acting as their own control. Various dynamic photoplethysmography variables were extracted to quantify pain intensity; the most accurate index was selected using logistic regression as a classifier. The area under the curve of the receiver-operating characteristic curve was measured to evaluate the accuracy of final model predictions. In total, 12,012 heart beats from 89 patients were used to develop a new Nasal Photoplethysmography Index for analgesic depth quantification. The two-variable model (a combination of diastolic peak point variation and heart beat interval variation) was most accurate in discriminating between the presence and absence of pain (numerical rating scale (NRS) ≥ 3). The accuracy and area under the curve of the receiver-operating characteristic curve for the Nasal Photoplethysmography Index were 75.3% and 0.8018, respectively, and 64.8% and 0.7034, respectively, for the Surgical Pleth Index. The Nasal Photoplethysmography Index clearly distinguished pain (NRS ≥ 3) in awake surgical patients with postoperative pain. The Nasal Photoplethysmography Index performed better than the Surgical Pleth Index. Further validation studies are needed to evaluate its feasibility to quantify pain intensity during general anaesthesia.

Abstract
OBJECTIVE This study aimed to evaluate whether urinary monocyte chemoattractant protein-1 (MCP-1) could serve as a biomarker for lupus nephritis (LN). METHODS We performed a meta-analysis to examine the relationship between urinary MCP-1 level and LN in three comparisons: active LN versus inactive LN, active LN versus control, and inactive LN versus control. RESULTS Eight studies of a total of 399 patients with LN (204 with active LN, and 195 with inactive LN) and 130 controls were available for this meta-analysis. The meta-analysis revealed that the urinary MCP-1 level was significantly higher in the active-LN group than in the inactive-LN group (standard mean difference [SMD] = 1.883, 95 % confidence interval [CI] = 0.811-2.954, p = 0.001). The meta-analysis showed that the urinary MCP-1 level was significantly higher in the active-LN group than in the control group (SMD = 3.085, 95 % CI = 1.684-4.485, p = 1.6 × 10-5). Furthermore, stratification by ethnicity showed significantly elevated urinary MCP-1 levels in the active-LN group in Caucasian, Asian, and Egyptian populations (SMD = 2.408, 95 % CI = 1.711-3.105, p < 1.0 × 10-8; SMD = 1.020, 95 % CI = 0.623-2.153, p = 4.6 × 10-7; and SMD = 7.370, 95 % CI = 1.467-2.157, p = 5.9 × 10-5, respectively). The meta-analysis indicated that the urinary MCP-1 level was also significantly higher in the inactive-LN group than in the control group (SMD = 1.812, 95 % CI = 0.628-2.996, p = 0.003). CONCLUSIONS The meta-analysis demonstrated that urinary MCP-1 was significantly higher in patients with active LN than in those with inactive LN and control subjects, and the patients with inactive LN showed significantly higher urinary MCP-1 levels than the controls.

Abstract
BACKGROUND Behçet disease (BD) is a chronic inflammatory disease. Adipokines are synthesized in adipose tissue, and have been reported to play important roles in the pathogenesis of autoimmune and inflammatory diseases, including BD. AIM To evaluate the relationship between circulating blood adipokine levels and BD. METHODS We conducted a meta-analysis of papers reporting on serum/plasma resistin, leptin, adiponectin and visfatin levels in patients with BD and in healthy controls (HCs). We identified 82 relevant studies using electronic and manual search methods, and selected 16 studies for full-text review based on the title and abstract. Two of these were later excluded (one was a review, one had no data), leaving 14 articles that met the inclusion criteria for this meta-analysis. RESULTS The 14 included studies assessed 637 patients with BD and 520 HCs. Compared with the HCs, the BD group had significantly higher levels of leptin [standardized mean difference (SMD) = 0.68, 95% CI 0.15-1.21, P = 0.01]. Levels of resistin (SMD = 0.51, 95% CI 0.92-0.918, P = 0.02) and adiponectin (SMD = 0.31, 95% CI 0.06-0.56, P = 0.02) were significantly higher in the BD group after adjustment for age, sex and body mass index (BMI), but not without such adjustment (resistin: (SMD = 0.38, 95% CI -0.18 to 0.93, P = 0.19; adiponectin: SMD = -0.59, 95% CI -2.23 to 1.06, P = 0.48). A significantly lower visfatin level was found in the BD group with adjustment (SMD = -1.70, 95% CI -2.14 to -1.25, P < 0.001) but not without adjustment (SMD = 0.31, 95% CI -0.21 to 0.82, P = 0.24). CONCLUSIONS Our meta-analysis revealed significantly higher circulating resistin, leptin and adiponectin levels and lower visfatin levels in patients with BD than in HCs, indicating that adipokines probably play an important role in BD pathogenesis.

Abstract
BACKGROUND Psoriasis is a chronic, autoimmune, inflammatory skin disorder. 25-hydroxy vitamin D [25(OH)D] deficiency may contribute to the pathogenesis of psoriasis through reduction in antiproliferative, anti-inflammatory and antiangiogenic activities. AIM To evaluate the relationship between circulating 25(OH)D levels and psoriasis, and to determine the correlation between serum/plasma 25(OH)D levels and psoriasis severity. METHODS We performed a meta-analysis to compare serum/plasma 25(OH)D levels between patients with psoriasis and healthy controls (HCs), and to determine the correlation coefficients between circulating 25(OH)D levels and psoriasis severity as assessed by Psoriasis Area and Severity Index (PASI). RESULTS Ten articles with a total of 571 patients with psoriasis and 496 HCs were included. The 25(OH)D level was significantly lower in the psoriasis group than in the HC group. Subgroup analysis by sample size revealed a significantly lower level of 25(OH)D in the psoriasis group for large (N > 80) but not for small (N < 80) sample sizes. Stratification by adjustment for age and/or sex or sample type revealed a significantly lower 25(OH)D level in the psoriasis group after adjustment for serum but not after nonadjustment for plasma. Meta-analysis of the correlation coefficients revealed a small but statistically significant positive correlation between circulating 25(OH)D levels and PASI. CONCLUSIONS This meta-analysis demonstrated that circulating 25(OH)D levels are lower in patients with psoriasis, and that a small but statistically significant negative correlation exists between 25(OH)D levels and psoriasis severity.
