Abstract: To describe the association of age, sex and body mass index with the rate of change of tibial knee cartilage volume over 10.7 years in a community-based s le of older adults. Four hundred and eighty-one participants (49% female, mean age 60.8 years [range 51.1–79.7], 49% had knee pain and 58% radiographic osteoarthritis) were included. Tibial cartilage volume of the right knee was assessed on T1-weighted fat-suppressed 1.5 T MRI at baseline and 10.7 years. Data analyses were performed using linear regression models. The average rate of loss of cartilage volume was 1.2%/year (range 0.2–3.9%) with all participants losing cartilage volume over the study period. There was a significant association between age and loss of tibial cartilage volume in the medial (0.023%/year, 95% confidence interval [CI] 0.010 to 0.036%, p 0.001), lateral (0.013%/year, 95% CI 0.003 to 0.023%, p = 0.012) and total tibia (0.018%/year, 95% CI 0.009 to 0.026%, p 0.001). Higher body mass index at baseline and increases in body mass index over time were associated with a greater tibial cartilage loss at the medial (body mass index at baseline 0.040%/year, 95% CI 0.022 to 0.058%, p 0.001 increases in body mass index 0.055%/year, 95% CI 0.018 to 0.093%, p = 0.004) but not lateral compartment. No evidence of non-linear relationships was observed. Compared to males, females lost more lateral tibial cartilage with increasing age (0.023%/year, 95% CI 0.003 to 0.043%, p = 0.024 for interaction). Tibial cartilage volume declines at a faster rate with increasing age and body mass index in both males and females, particularly in the medial compartment. In contrast to the low rate of change in radiographs, our findings suggest that cartilage loss at the tibia is universal in this age group.

Abstract: It has been reported that two single nucleotide polymorphisms (SNP) Taq1A and -141C Ins/Del in the DRD2 gene may be associated with susceptibility to schizophrenia. Due to inconclusive and mixed results, a meta-analysis was conducted to further clarify the relationship between the two SNP and schizophrenia susceptibility. A systematic literature search for the association of these two SNP with schizophrenia susceptibility was conducted using PubMed, ScienceDirect, Chinese Biomedical Literature Database, and Chinese National Knowledge Infrastructure. Odds ratios (OR) with 95% confidence intervals (CI) were used to assess the strength of the associations reported. A total of 5558 schizophrenic patients and 6792 healthy controls from 31 articles were included in this study. Evidence regarding the association between -141C Ins/Del polymorphism and schizophrenia was found in the allele frequency comparison (Ins versus Del: OR 1.29, 95% CI 1.06-1.57 p=0.01, Praw=0.1, PFalse Discovery Rate=0.023). In ethnic subgroup analysis, the result revealed that the 141C Ins/Del polymorphism was associated with schizophrenia in all genetic models in Asians, but not in Caucasians. For Taq1A polymorphism, a significant association was found in the allele frequency (A1 versus A2: OR 0.71, 95% CI 0.52-0.98, p=0.03). Stratification by ethnicity indicated an association between the Taq1A polymorphism and schizophrenia in Asians, but not Caucasians. The present study suggests that the -141C Ins/Del polymorphism carries a significantly increased risk of schizophrenia, while the Taq1A polymorphism carries a significantly decreased risk of schizophrenia susceptibility in Asians.

Abstract: Physical inactivity is an independent risk factor for type 2 diabetes (T2D). Osteoarthritis (OA) is a common joint disease that limits patients' physical activity, which may increase risk of other chronic diseases including T2D. However, studies evaluating the effect of OA on T2D are scarce. This study aimed to investigate the causal effect of knee and hip OA on risk of T2D from a genetic perspective. We performed two‐s le Mendelian randomization (MR) analyses to obtain nonconfounding estimates of the effect of OA on T2D risk. Single nucleotide polymorphisms (SNPs) from genome‐wide association studies were selected as genetic instruments for radiographic knee and hip OA (ie, Kellgren–Lawrence grade ≥2). The associations of these SNPs with T2D were evaluated in participants from the UK Biobank. Sensitivity analyses were conducted to test the robustness of the MR results. Genetic predisposition of knee but not hip OA was significantly associated with an increased risk of T2D (knee OA: odds ratio [OR] 1.18, 95% confidence interval (CI) 1.09–1.27, p .001 hip OA: OR 1.04, 95% CI 0.94–1.16, p = .425). Sensitivity analyses showed that the main findings are robust. The current study provides genetic evidence supporting that knee OA is a potential risk factor for T2D.

Abstract: Schizophrenia is a common, complex multi-factorial psychiatric disorder. Many studies have reported associations between the C957T and C939T polymorphisms in Dopamine D2 receptor (DRD2) gene and schizophrenia, but results are inconsistent. To derive a more precise estimation of the relationship, a meta-analysis was conducted to systematically summarize the possibility. We included 13 articles involving 3079 schizophrenia cases and 3851 healthy controls. Positive associations were found between C957T polymorphism and schizophrenia risk in C vs. T (OR=1.26, 95% CI=1.09-1.46, Praw=0.002, PFDR=0.005) and CC+CT vs. TT (OR=1.47, 95% CI=1.25-1.73, Praw<0.001, PFDR<0.001). When stratified by race, a significantly increased risk of schizophrenia was observed in Caucasians, but not in Asians. No association between C939T polymorphism and schizophrenia was found in overall or Asian population. Our study suggested that C957T of DRD2 gene polymorphism is likely to be a risk factor for schizophrenia, especially in Caucasian.

Abstract: Background. Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous non-Hodgkin’s lymphoma with great clinical challenge. Machine learning (ML) has attracted substantial attention in diagnosis, prognosis, and treatment of diseases. This study is aimed at exploring the prognostic factors of DLBCL by ML. Methods. In total, 1211 DLBCL patients were retrieved from Huaihai Lymphoma Working Group (HHLWG). The least absolute shrinkage and selection operator (LASSO) and random forest algorithm were used to identify prognostic factors for the overall survival (OS) rate of DLBCL among twenty-five variables. Receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were utilized to compare the predictive performance and clinical effectiveness of the two models, respectively. Results. The median follow-up time was 43.4 months, and the 5-year OS was 58.5%. The LASSO model achieved an Area under the curve (AUC) of 75.8% for the prognosis of DLBCL, which was higher than that of the random forest model (AUC: 71.6%). DCA analysis also revealed that the LASSO model could augment net benefits and exhibited a wider range of threshold probabilities by risk stratification than the random forest model. In addition, multivariable analysis demonstrated that age, white blood cell count, hemoglobin, central nervous system involvement, gender, and Ann Arbor stage were independent prognostic factors for DLBCL. The LASSO model showed better discrimination of outcomes compared with the IPI and NCCN-IPI models and identified three groups of patients: low risk, high-intermediate risk, and high risk. Conclusions. The prognostic model of DLBCL based on the LASSO regression was more accurate than the random forest, IPI, and NCCN-IPI models.

Abstract: To explore the association of β-defensin gene copy number variations (CNVs) with ankylosing spondylitis (AS). In this study, 405 unrelated Chinese Han patients with AS and 401 unrelated healthy controls were enrolled. The copy numbers of DEFB4 gene (2 fragments) were measured by AccuCopy™ methods. The association of DEFB4 gene CNVs with AS susceptibility was analyzed by chi-square and logistic regression models. Besides, P values, odds ratio, and 95% confidence intervals (CIs) were used to estimate the effects of risk. The range of DEFB4_1 CN was 0-7 and the range of DEFB4_2 CN was 1-8 both in patients and controls. P values of χ(2) trend test for the association of DEFB4_1 and DEFB4_2 with AS were 0.607 and 0.005, respectively. The results of DEFB4_2, compared with the in idual having median 3 copies, those carrying ≤ 2-copies [OR = 0.68, 95%CI: (0.46, 0.99), P = 0.049 adjusted OR = 0.69, 95%CI(0.47, 1.03), P = 0.067.] and those carrying ≥ 4-copies [OR = 0.62, 95%CI: (0.45, 0.86), P = 0.004 adjusted OR = 0.64, 95%CI: (0.46, 0.88), P = 0.006], were significantly associated with decreasing risk of AS. Univariate analysis showed that both DEFB4_1 and DEFB4_2 were associated with Bath AS Disease Activity Index or BASDAI. After adjusted by age, sex, and disease duration, the results changed little, which demonstrated that high copies may be linked with decrease in the risk of disease severity [OR = 0.71, 95%CI: (0.56, 0.90), P = 0.005 OR = 0.75, 95%CI: (0.60, 0.94), P = 0.013, respectively]. The CNs of DEFB4 gene may be associated with AS and involved in disease progression.

Abstract: To describe the association between change in subchondral bone marrow lesions (BMLs) and change in tibiofemoral cartilage volume and knee symptoms in patients with symptomatic knee OA. In total, 251 participants (mean 61.7 years, 51% female) were included. Tibiofemoral cartilage volume was measured at baseline and 24 months, and BML size at baseline, 6 and 24 months. Knee pain and function scores were evaluated at baseline, 6 and 24 months. Change in total and compartment-specific BML size was categorized according to the Least Significance Criterion. Linear mixed-effects models were used to evaluate the associations of change in BMLs over 6 and 24 months with change in cartilage volume over 24 months and knee symptoms over 6 and 24 months. Total BML size enlarged in 26% of participants, regressed in 31% and remained stable in 43% over 24 months. Compared with stable BMLs in the same compartment, enlarging BMLs over 24 months were associated with greater cartilage loss (difference: −53.0mm3, 95% CI: −100.0, −6.0), and regressing BMLs were not significantly associated with reduced cartilage loss (difference: 32.4mm3, 95% CI: −8.6, 73.3) over 24 months. Neither enlargement nor regression of total BML size over 6 and 24 months was associated with change in knee pain and function over the same time intervals. In subjects with symptomatic knee osteoarthritis and BMLs, enlarging BMLs may lead to greater cartilage loss but regressing lesions are not associated with reduced cartilage loss while neither is associated with change in knee symptoms.

Abstract: We investigated whether TESPA1 gene polymorphisms were associated with increased risk of developing ankylosing spondylitis (AS). We also studied whether TESPA1 gene interacts with environmental factors. A total of 494 patients with AS and 478 matched healthy controls were genotyped for four SNPs (rs1801876, rs2171497, rs4758994, and rs997173) in the TESPA1 gene. We found no evidence of association between these SNPs and AS susceptibility, and between their haplotypes and the disease. But, patients with rs1801876 GA, GG, and AA genotypes had significantly different Bath Ankylosing Spondylitis Functional Index (BASFI) scores (p = 0.023). There were significantly different visual analogue scale (VAS) night pain assessment scores (p = 0.040) and BASFI scores (p = 0.023) among different genotypes at rs2171497 locus. There were also significantly different chest expansion scores (p = 0.042) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores (p = 0.014) among different genotypes at rs997173 locus. For multiple testing, Bonferroni correction was performed. After Bonferroni correction, clinical characteristics of these three loci showed association between different genotype groups. These findings indicated that the TESPA1 gene is not involved in AS genetic predisposition in the Han Chinese population however, it may play an important role in the clinical characteristics of AS.

Abstract: The relationship between the SLC2A9 (solute carrier family 2, member 9) gene polymorphisms and gout was still inconsistent among the in idual genetic association studies. Therefore, this present research was aimed to systematically evaluate the association between SLC2A9 gene polymorphisms and gout susceptibility. Relevant studies were enrolled by searching databases systematically. The pooled odds ratios (ORs) with 95 % confidence intervals (CIs) were used to assess the associations. The heterogeneity between each of the studies was calculated by using the Q statistic methods, and Begg's funnel plot and Egger's tests were performed to evaluate publication bias. A total of 13 studies investigated four single nucleotide polymorphisms (SNPs) in SLC2A9 were included. In this study, we found that the allele C of rs3733591 was higher in patients than in controls in both all-pooled population [C vs. T: OR (95 % CI) = 1.432 (1.213-1.691)] and Asians-pooled population [C vs. T: OR (95 % CI) = 1.583 (1.365-1.835)]. The allele frequency C of s6449213 was lower in the gout patients than in controls in both all-pooled population and Caucasians-pooled population. Additionally, the allele frequency T of rs16890979 and the allele frequency C of rs1014290 were lower in gout patients than in controls. This study demonstrated that the genetic susceptibility for gout is associated with the SLC2A9 gene polymorphisms. Four of them except for the rs3733591 are protective SNPs in Caucasians, and rs16890979 and rs1014290 are protective SNPs in both Caucasians and Asians, while rs3733591 may be susceptibility SNP in Asians.

Abstract: The relationship between circulating follicular helper T (Tfh) cells and ankylosing spondylitis (AS) remains unclear. The aims of our study were to measure the levels of circulating Tfh cells and several related parameters in patients with AS, and examine the correlation of these factors with disease activity. We designated CD4 + CXCR5 + ICOS+ T cells as circulating Tfh cells. The percentage of circulating Tfh cells was detected using flow cytometry. Plasma IL-21 and immunoglobulin (IgA, IgM, and IgG) levels were quantified using enzyme-linked immunosorbent assay in 60 AS patients and 60 healthy controls (HC). The percentage of circulating Tfh cells was increased in AS patients compared with that in HC. As AS patients were ided into active and inactive groups, the percentage of circulating Tfh cells was significantly increased in active group compared with both inactive group and HC. Plasma IL-21 and immunoglobulin levels were elevated in AS patients, and the differences were significant except IgG. In addition, the percentage of circulating Tfh cells was positively correlated with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and plasma IL-21 levels were positively correlated with plasma immunoglobulin levels. But neither circulating Tfh cells nor BASDAI was significantly correlated with plasma IL-21 and immunoglobulin levels in AS patients, with the exception of significant correlation between BASDAI and plasma IgM levels in active AS patients. Our study has shown the increased percentage of circulating Tfh cells correlated with disease activity, and the high plasma IL-21 levels were associated with high plasma immunoglobulin levels in patients with AS, indicating that the circulating Tfh cells may be associated with the development of AS.

Abstract: To evaluate the effect of annual infusions of zoledronic acid (ZA) with or without a single injection of methylprednisolone, compared to placebo, on quantitative magnetic resonance imaging 3-D bone area and bone shape in participants with symptomatic knee osteoarthritis (OA). This was a post-hoc analysis of the ZAP2 trial. Active appearance modelling was used to assess bone area (mm At baseline 65% of participants demonstrated an OA shape. Treatment with ZA plus methylprednisolone but not ZA alone, compared to placebo, was associated with significantly slower expansion in bone area at the medial femoral (-33.9 mm ZA plus methylprednisolone may retard expansion of bone area over 24 months, but ZA alone may not. Neither ZA with or without methylprednisolone slowed progression of bone shape over 6 or 24 months.

Abstract: The aim of this study was to compare the efficacy and safety of zoledronic acid (ZA) plus intravenous methylprednisolone (VOLT01) to ZA, and placebo for knee osteoarthritis. A single-center, double-blind, randomized controlled trial (RCT) was carried out. Adults (aged ⩾50 years) with knee osteoarthritis, significant knee pain [⩾40 mm on a 100 mm visual analog scale (VAS)], and magnetic resonance imaging-detected bone marrow lesion (BML) were randomized to receive a one-off administration of VOLT01, ZA, or placebo. The primary hypothesis was that VOLT01 was superior to ZA in having a lower incidence of acute phase responses (APRs) over 3 days. Secondary hypotheses were that VOLT01 was noninferior to ZA, and both treatments were superior to placebo in decreasing BML size over 6 months and in improving knee pain [Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and VAS] and function (WOMAC) over 3 and 6 months. A total of 117 patients (62.2 ± 8.1 years, 63 women) were enrolled. The incidence of APRs was similar in the VOLT01 (90%) and ZA (87%) groups ( p = 0.74). VOLT01 was superior to ZA in improving knee pain and function after 6 months and noninferior to ZA in reducing BML size. However, BML size change was small in all groups and there were no between-group differences. Compared with placebo, VOLT01 but not ZA improved knee function and showed a trend toward improving knee pain after 6 months. Administering intravenous methylprednisolone with ZA did not reduce APRs or change knee BML size over 6 months, but in contrast to ZA or placebo, it may have a beneficial effect on symptoms in knee osteoarthritis.

Abstract: In this brief communication, we investigate the role of DEFB103 gene copy number variation (CNV) in ankylosing spondylitis (AS) susceptibility. A total of 807 Chinese in iduals including 406 AS patients and 401 controls were enrolled. The DEFB103 copy number was measured by two sets of probes to obtain a stable result in a custom-by-design Multiplex AccuCopy(™) kit (Genesky Biotechnologies Inc., Shanghai, China) based on a multiplex fluorescence competitive polymerase chain reaction (PCR) principle. The copy number of DEFB103 ranged from 2 to 6 in both AS patients and controls. Mann-Whitney U test and chi-squared test were performed to analyze the difference of DEFB103 copy number between AS patients and controls while no statistical difference has been found. We considered the copy number of DEFB103 gene may not associate with susceptibility to AS.

Abstract: We assessed whether the vitamin D receptor gene polymorphisms (FokI, BsmI, ApaI, and TaqI) were associated with ankylosing spondylitis (AS) in a Chinese Han population. The TaqI polymorphism G allele was a risk factor in AS susceptibility. Previous studies have found that serum vitamin D levels are declined in patients with AS. The present study aims to evaluate the role of vitamin D receptor (VDR) gene polymorphisms in AS susceptibility in a Chinese Han population. Four single nucleotide polymorphisms (SNPs) in the VDR gene (FokI (rs2228570), BsmI (rs1544410), ApaI (rs7975232), and TaqI (rs731236)) were genotyped by the improved multiplex ligase detection reaction (iMLDR) method in 620 AS patients and 620 geographically and ethnically matched healthy controls. Haplotypes were constructed after linkage disequilibrium (LD) analysis. Statistically significant difference was only found in the TaqI polymorphism between AS patients and controls. The TaqI polymorphism G allele was higher in AS group than that in controls (OR [95 % CI] = 1.624 [1.122-2.352], χ (2) = 6.705, P = 0.006). Linkage disequilibrium has been detected in TaqI and BsmI polymorphisms (D' = 0.87, r (2) = 0.70). Two novel haplotypes (H1: AC and H2: GT) were significantly associated with the risk of AS, and they play protective and risk roles in AS morbidity, respectively. The VDR gene TaqI polymorphism G allele may be a risk factor in AS susceptibility.

Abstract: To describe the effect of knee symptoms and radiographic osteoarthritis (ROA) on the risk of falls, recurrent falls, and fractures. Participants from the Osteoarthritis Initiative were classified as having 'no', 'unilateral' or 'bilateral' knee symptoms (≥19 on a 0-96 Western Ontario and McMaster Universities Osteoarthritis Index) and ROA (Kellgren-Lawrence grade ≥2) for each visit. Self-reported falls and fractures in the past 12 months were extracted at baseline and follow-up visits until month 96. Recurrent falls were defined as having ≥2 falls in the past 12 months. Hazard ratios (HR) with 95% confidence intervals (CI) were estimated using mixed-effects complementary log-log regression. Of 4465 participants, 3145 (70%), 1681 (38%), and 806 (18%) experienced at least one fall, recurrent fall, and fracture, respectively, over 96 months. Compared to participants without symptomatic knee, unilateral and bilateral knee symptoms were associated with a 17% increased risk of falls and a 36-46% increased risk of recurrent falls, and bilateral knee symptoms increased the risk of fractures (HR 1.45, 95%CI 1.17 to 1.81). Compared to participants with no ROA in either knee, bilateral ROA was associated with a reduced risk of falls (HR 0.87, 95%CI 0.77 to 0.99) and fractures (HR 0.78, 95%CI 0.64 to 0.96). No statistically significant interactions between knee symptoms and ROA were observed. This large population-based study showed that knee symptoms but not ROA increased the risk of falls, recurrent falls, and fractures, and that adults with bilateral ROA may have a lower risk of falls and fractures.

Abstract: Since March 2020, when the COVID19 pandemic hit Australia, Victoria has been in lockdown six times for 264 days, making it the world’s longest cumulative locked-down city. This Health Impact Assessment evaluated gender disparities, especially women’s mental health, represented by increased levels of psychological distress during the lockdowns. A desk-based, retrospective Health Impact Assessment was undertaken to explore the health impacts of the lockdown public health directive with an equity focus, on the Victorian population, through reviewing available qualitative and quantitative published studies and grey literature. Findings from the assessment suggest the lockdown policies generated and perpetuated avoidable inequities harming mental health demonstrated through increased psychological distress, particularly for women, through psychosocial determinants. Ongoing research is needed to elucidate these inequities further. Governments implementing policies to suppress and mitigate COVID19 need to consider how to reduce harmful consequences of these strategies to avoid further generating inequities towards vulnerable groups within the population and increasing inequalities in the broader society.

Abstract: No consensus has been reached on sexual dysfunction in men with ankylosing spondylitis (AS). Our study aimed to derive a more precise estimation of the sexual function and its clinical correlations in men with AS. A metaanalysis was performed and the related literature were searched in PubMed, Elsevier Science Direct, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, and in reference lists of articles and systematic reviews. Score of the International Index of Erectile Function (IIEF) was used as the outcome measurement, and standardized mean differences (SMD) with 95% CI were calculated. Eleven studies were included, including 535 men with AS and 430 male controls. Each domain of the IIEF score (erectile function: SMD −0.52, 95% CI −0.68 – −0.37 orgasmic function: −0.72, −1.03 – −0.42 sexual drive: −0.40, −0.62 – −0.18 intercourse satisfaction: −0.86, −1.15 – −0.56 and overall satisfaction: −0.61, −0.91 – −0.32) were lower in men with AS than in controls. In the subgroup analysis, the results did not change except for the sexual drive in the Asians group (−0.15, −0.42–0.13). At metaregression, no study characteristics were significantly associated with effect size of the IIEF score. Sexual function is impaired in male patients with AS and further studies are necessary to better understand risk factors for sexual dysfunction in this population.

Abstract: Many publications with conflicting results have evaluated serum levels of copper (Cu) and zinc (Zn) in patients with rheumatoid arthritis (RA). To derive a more precise estimation of the relationship, a meta-analysis was conducted. Relevant published data were retrieved through PubMed, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biomedical Database (CBM) before September 20, 2014. Weighted mean difference (WMD) with a 95 % confidence interval (95 % CI) was calculated using STATA 11.0. A total of 26 studies, including 1444 RA cases and 1241 healthy controls, were collected in this meta-analysis. Pooled analysis found that patients with RA had a higher serum level of Cu and a lower serum Zn level than the healthy controls (Cu (μg/dl), WMD = 31.824, 95 % CI = 20.334, 43.314 Zn (μg/dl), WMD = -12.683, 95 % CI = -19.783, -5.584). Subgroup analysis showed that ethnicity had influence on the serum level of Cu (μg/dl) (Caucasian, WMD = 43.907, 95 % CI = 35.090, 52.723, P < 0.001 Asian, WMD = 14.545, 95 % CI = -12.365, 41.455, P = 0.289) and Zn (μg/dl) (Caucasian, WMD = -11.038, 95 % CI = -23.420, 1.344, P = 0.081 Asian, WMD = -14.179, 95 % CI = -18.963, -9.394, P < 0.001) in RA and healthy controls. No evidence of publication bias was observed. This meta-analysis suggests that increased serum level of Cu and decreased serum level of Zn are generally present in RA patients.

Abstract: There is an unmet need for treatments for knee osteoarthritis (OA). Effusion-synovitis is a common inflammatory phenotype of knee OA and predicts knee pain and structural degradation. Anti-inflammatory therapies, such as diacerein, may be effective for this phenotype. While diacerein is recommended for alleviating pain in OA patients, evidence for its effectiveness is inconsistent, possibly because studies have not targeted patients with an inflammatory phenotype. Therefore, we will conduct a multi-centre, randomised, placebo-controlled double-blind trial to determine the effect of diacerein on changes in knee pain and effusion-synovitis over 24 weeks in patients with knee OA and magnetic resonance imaging (MRI)-defined effusion-synovitis. We will recruit 260 patients with clinical knee OA, significant knee pain, and MRI-detected effusion-synovitis in Hobart, Melbourne, Adelaide, and Perth, Australia. They will be randomly allocated to receive either diacerein (50mg twice daily) or identical placebo for 24 weeks. MRI of the study knee will be performed at screening and after 24 weeks of intervention. The primary outcome is improvement in knee pain at 24 weeks as assessed by a 100-mm visual analogue scale (VAS). Secondary outcomes include improvement in volumetric (ml) and semi-quantitative (Whole-Organ Magnetic Resonance Imaging Score, 0–3) measurements of effusion-synovitis using MRI over 24 weeks, and improvement in knee pain (VAS) at 4, 8, 12, 16, and 20 weeks. Intention-to-treat analyses of primary and secondary outcomes will be performed as the primary analyses. Per protocol analyses will be performed as the secondary analyses. This study will provide high-quality evidence to determine whether diacerein improves pain, changes disease trajectory, and slows disease progression in OA patients with effusion-synovitis. If diacerein proves effective, this has the potential to significantly benefit the substantial proportion (up to 60%) of knee OA patients with an inflammatory phenotype.

Abstract: The results of studies on association between KIR (killer cell immunoglobulin-like receptors) polymorphisms and susceptibility to RA (rheumatoid arthritis) are inconsistent. To comprehensively evaluate the effect of KIR polymorphisms on the risk of RA, a meta-analysis was carried out. The Web of Science, PubMed, the Chinese Biomedical Database (CBM) and Chinese National Knowledge Infrastructure (CNKI) databases were systematically searched to select studies on the association between KIR polymorphisms and RA. The odds ratio (OR) with 95% confidence interval (95%CI) was obtained. Nine qualified case-control studies were included in this meta-analysis. The results showed there were two positive associations of 2DL1, 2DS1 (OR2DL1=2.20, 95%CI=1.20-4.01, Praw=0.01, PFDR=0.03 OR2DS1=1.84, 95%CI=1.19-2.85, Praw=0.006, PFDR=0.018) and one negative association of 2DL3 (OR2DL3=0.42, 95%CI=0.22-0.79, Praw=0.006, PFDR=0.018) with susceptibility to RA in East Asians, but not in Caucasians. The current meta-analysis provides evidence that 2DL3 might be a potential protective factor and 2DL1, 2DS1 might be risk factors for RA in East Asians but not in Caucasians.

Abstract: The relationship between the endoplasmic reticulum aminopeptidase 1 (ERAP1) polymorphisms and ankylosing spondylitis (AS) was inconsistent in the recent literatures, a meta-analysis was therefore performed. A total of 25 independent studies with 24,271 AS patients and 42,666 controls were included after searching electronic databases for studies published before June 2014. The pooled and in idual odds ratios (ORs) with 95% confidence intervals (CIs) were presented to assess the associations between ERAP1 polymorphisms and AS in different ethnicities. This meta-analysis includes 25 studies that investigate 8 single nucleotide polymorphisms (SNPs rs17482078, rs30187, rs2287987, rs27044, rs26653, rs10050860, rs27037, and rs27434) in ERAP1 gene. Overall, six SNPs were associated with AS two SNPs (rs27044 and rs26653) were not when all studies were pooled into the meta-analysis (rs27044 G vs. C, OR = 1.058, 95% CI = 0.827-1.354 rs26653 C vs. G, OR = 1.154, 95% CI = 0.937-1.422). In Caucasians, all the 8 SNPs were significantly associated with AS. But 5 SNPs (rs17482078, rs2287987, rs27044, rs26653, and rs10050860) did not show statistical association with the risk of AS in Asians. ERAP1 polymorphisms were associated with AS in Caucasians, but their association with AS in Asians needs further exploration.

Abstract: To summarize effects of intravenous bisphosphonates (IVBP) in patients with symptomatic knee OA and bone marrow lesions (BMLs), using a meta-analysis of randomized controlled trials (RCTs). Literature databases were searched for placebo-controlled RCTs of IVBPs for knee OA from inception, and included validated pain and function scales, BML size and incidence of adverse events. Efficacy was compared using standardized mean differences (SMD) and risk ratios (RR) with fixed-effect or random-effects models. Methodological quality was assessed using the Cochrane risk of bias tool, heterogeneity was assessed by I2 statistics. We included 428 patients in four RCTs of 2–24 months duration most patients (84%) received zoledronic acid (ZA). Risk of bias was low-moderate. IVBP had large effect sizes on pain within 3 months [SMD = −2.33 (95% CI: −3.02, −1.65)] mainly driven by neridronate (resulting in substantial heterogeneity, I2 = 92%) with no effect for ZA alone. Differences in knee function were statistically significant at 3 months [SMD = −0.22 (−0.43, −0.01), I2 = 0.2%]. Effect sizes for pain did not reach statistical significance at any other time point. IVBPs improved a semi-quantitative measure of BML size within 6 months [SMD = −0.52 (−0.89, −0.14), I2 = 0%] but not at 12 months or two years. Adverse events [RR = 1.19 (1.00, 1.41) I2 = 52%], occurred more frequently with IVBP. ZA has no effect on knee pain, possibly a short-term effect on BML size and higher rates of adverse events. Neridronate may improve pain in the short term, but this is based on a single trial.

Abstract: The role of vitamin D in ankylosing spondylitis (AS) is largely unknown. This paper aims to examine the association between serum vitamin D levels and susceptibility and disease activity of AS. We searched the relevant literatures in PubMed, Elsevier Science Direct, Chinese Biomedical Database (CBM), Chinese National Knowledge Infrastructure (CNKI) and Wanfang (Chinese) Database published before June 2014. Eight independent case-control studies with a total of 533 AS patients and 478 matching controls were selected into this meta-analysis. Standard mean differences (SMDs) with 95% confidence intervals (CIs) were used to assess the levels of serum vitamin D, parathyroid hormone (PTH), serum calcium and alkaline phosphatase (ALP) in cases and controls, respectively. Correlation coefficients (CORs) have been performed to value the correlationship between vitamin D and disease activity (erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)) of AS patients. Meta-analysis results suggested that vitamin D may play a protective role in AS (for total vitamin D: SMD=-0.71, P<0.001 for 25OHD: SMD=-0.66, P=0.002 for 1,25OHD: SMD=-0.72, P=0.19). Differences in PTH and serum calcium levels were not significant in AS (SMD=-0.10, P=0.67 SMD=0.12, P=0.17 respectively), while ALP was associated with AS susceptibility (SMD=0.20, P=0.04). The relationship between serum vitamin D levels and disease activity was statistically significant except for 25OHD versus (vs.) CRP or BASDAI (for CRP vs. 25OHD: COR=-0.22, P=0.08 for BASDAI vs. 25OHD: COR=-0.20, P=0.06, respectively). The higher levels of serum vitamin D were associated with a decreased risk of AS, and showed an inverse relationship with AS activity.

Abstract: Ankylosing spondylitis (AS) is a common inherited autoimmune disease. Copy number variation (CNV) of DNA segments has been found to be an important part of genetic variation, and the FCGR3A and FCGR3B gene CNVs have been associated with various autoimmune disorders. The aim of the study was to determine whether CNVs of FCGR3A and FCGR3B were also associated with the susceptibility of AS. A total of 801 in iduals including 402 AS patients and 399 healthy controls were enrolled in this study. The copy numbers of FCGR3 gene (two fragments, included FCGR3A and FCGR3B) were measured by AccuCopy™ methods. Chi-square test and logistic regression model were used to evaluate association between FCGR3 gene CNVs and AS susceptibility. P values, odds ratio, and 95% confidence intervals (CIs) were used to estimate the effects of risk. Significantly, difference in the frequencies of FCGR3A and FCGR3B gene CNVs was founded between the patients with AS and controls. For the FCGR3A gene, a low (≤3) copy number was significantly associated with AS [for ≤3 copies versus 4 copies, (OR 2.17, 95% CI (1.41, 3.34), P < 0.001, adjusted OR 2.22, 95% CI (1.44, 3.43), P < 0.001)]. A low FCGR3B copy number was also significantly associated with increasing risk of AS [for ≤3 copies versus 4 copies, (OR 1.87, 95% CI (1.25, 2.79), P = 0.002, adjusted OR 1.94, 95% CI (1.29, 2.91), P = 0.001)] however, both the high FCGR3A and FCGR3B copy numbers (≥5) were not significantly associated with the risk of AS (≥5 copies versus 4 copies). The lower copy numbers (≤3) of FCGR3A and FCGR3B genes confer a risk factor for AS susceptibility.

Abstract: To investigate the relationship between sleep disturbance, catastrophizing, and knee pain in middle‐aged and older in iduals. Data from the Osteoarthritis Initiative cohort from months 48 to 96 were used, where month 48 was treated as baseline. Knee pain (Western Ontario and McMaster Universities Osteoarthritis Index pain scale score ≥5 [range 0–20]), catastrophizing (extracted from Coping Strategies Questionnaire score ≥3 [range 0–6]), and sleep quality (extracted from Center for Epidemiologic Studies Depression Scale [range 1–4]) were assessed annually. We described the association of sleep disturbance with the presence and risk of knee pain and catastrophizing. The mediation effect of knee pain and catastrophizing on the sleep–catastrophizing and sleep–pain association was evaluated, respectively. Catastrophizing and knee pain were reported in 346 (10%) and 917 (24%) of the 3,813 participants (mean 64.9 years, 58% female) at baseline. Participants with worse sleep disturbance were more likely to have knee pain (prevalence ratio [PR] 1.4–2.0, P for trend .001) and catastrophizing (PR 1.4–3.1, P for trend .001). Sleep disturbance at baseline predicted the risk of knee pain (risk ratio [RR] 1.1, P for trend .001) and catastrophizing (RR 1.2–1.7, P for trend .001) during follow‐up. No statistically significant interactions between sleep disturbance and knee pain or catastrophizing were observed. Knee pain and catastrophizing mediated the sleep–catastrophizing and sleep–pain association, respectively, at baseline, and knee pain negatively mediated the sleep–catastrophizing association longitudinally. Sleep disturbance was associated with the presence and risk of catastrophizing and knee pain. Sleep interventions may have a universal and independent effect in preventing incident knee pain.

Abstract: Frailty is a multisystem syndrome and its relationship with symptomatic osteoarthritis has been reported. We aimed to identify trajectories of knee pain in a large prospective cohort and to describe the effect of frailty status at baseline on the pain trajectories over 9 years. We included 4419 participants (mean age 61.3 years, 58% female) from the Osteoarthritis Initiative cohort. Participants were classified as “no frailty,” “pre-frailty,” or “frailty” at baseline, based on 5 characteristics (ie, unintentional weight loss, exhaustion, weak energy, slow gait speed, and low physical activity). Knee pain was evaluated annually using the Western Ontario and McMaster Universities Osteoarthritis Index pain subscale (0–20) from baseline to 9 years. Of the participants included, 38.4%, 55.4%, and 6.3% were classified as “no frailty,” “pre-frailty,” and “frailty,” respectively. Five pain trajectories were identified: “No pain” (n = 1010, 22.8%), “Mild pain” (n = 1656, 37.3%), “Moderate pain” (n = 1149, 26.0%), “Severe pain” (n = 477, 10.9%), and “Very Severe pain” (n = 127, 3.0%). Compared to participants with no frailty, those with pre-frailty and frailty were more likely to have more severe pain trajectories (pre-frailty: odds ratios [ORs] 1.5 to 2.1 frailty: ORs 1.5 to 5.0), after adjusting for potential confounders. Further analyses indicated that the associations between frailty and pain were mainly driven by exhaustion, slow gait speed, and weak energy. Approximately two-thirds of middle-aged and older adults were frail or pre-frail. The role of frailty in predicting pain trajectories suggests that frailty may be an important treatment target for knee pain.
