RESUMEN
OBJECTIVES: This phase 2b, randomised, double-blind, placebo-controlled trial evaluated the efficacy and safety of telitacicept, a novel fusion protein that neutralises signals of B lymphocyte stimulator and a proliferation-inducing ligand, in active systemic lupus erythematosus (SLE). METHODS: Adult patients with active SLE (n=249) were recruited from 29 hospitals in China and randomised 1:1:1:1 to receive subcutaneous telitacicept at 80 mg (n=62), 160 mg (n=63), 240 mg (n=62) or placebo (n=62) once weekly in addition to standard therapy. The primary endpoint was the proportion of patients achieving an SLE Responder Index 4 (SRI-4) response at week 48. Missing data were imputed using the last observation carried forward method. RESULTS: At week 48, the proportion of patients achieving an SRI-4 response was 75.8% in the 240 mg telitacicept group, 68.3% in the 160 mg group, 71.0% in the 80 mg group and 33.9% in the placebo group (all p<0.001). Significant treatment responses were observed in secondary endpoints, including a ≥4-point reduction on the Systemic Lupus Erythematosus Disease Activity Index, a lack of Physician's Global Assessment score worsening and a glucocorticoid dose reduction in the 240 mg group. Telitacicept was well tolerated, and the incidence of adverse events and serious adverse events was similar between the telitacicept and placebo groups. CONCLUSIONS: This phase 2b clinical trial met the primary endpoint. All telitacicept groups showed a significantly higher proportion of patients achieving an SRI-4 response than the placebo group at week 48, and all doses were well tolerated. These results support further investigations of telitacicept in clinical trials involving more diverse populations and larger sample sizes.

OBJECTIVE: To evaluate the efficacy and safety of telitacicept in adult patients with primary SS (pSS) in a phase II randomized double-blind placebo-controlled trial. METHODS: Patients with pSS with positive anti-SSA antibody and ESSDAI ≥ 5 were randomly assigned, in a 1:1:1 ratio, to receive weekly subcutaneous telitacicept 240 mg, 160 mg, or placebo for 24 weeks. The primary end point was the change from baseline in the ESSDAI at week 24. Safety was monitored. RESULTS: A total of 42 patients were enrolled and randomized (n = 14 per group). Administration of telitacicept 160 mg resulted in a significant reduction in ESSDAI score from baseline to week 24 compared with placebo (P < 0.05). The placebo-adjusted least-squares mean change from baseline was -4.3 (95% CI -7.0, -1.6; P = 0.002). While, mean change of ESSDAI in telitacicept 240 mg was -2.7(-5.6-0.1) with no statistical difference when compared that in placebo group (P = 0.056). In addition, MFI-20 and serum immunoglobulins decreased significantly (P < 0.05) at week 24 in both telitacicept groups compared with placebo. No serious adverse events were observed in the telitacicept treating group. CONCLUSION: Telitacicept showed clinical benefits and good tolerance and safety in the treatment of pSS.

BACKGROUND: Since the COVID-19 pandemic, several therapeutic agents have been used in COVID-19 management. However, the results were controversial. Here, we aimed to evaluate the efficacy and safety of hydroxychloroquine (HCQ)/chloroquine (CQ) in COVID-19. METHODS: We retrospectively reviewed the medical charts of patients with COVID-19 admitted to an inpatient ward in Wuhan from 2020/Feb/08 to 2020/Mar/05. Patients with HCQ/CQ and age, gender, disease severity matched ones without HCQ/CQ were selected at a 1:2 ratio. The clinical, laboratory and imaging findings were compared between these two groups. The multivariate linear regression analysis was performed to identify the factors that might influence patients' virus shedding periods (VSPs). RESULTS: A total of 14 patients with HCQ/CQ and 21 matched ones were analyzed. The HCQ/CQ treatment lasted for an average of 10.36 ± 3.12 days. The mean VSPs were longer in the HCQ/CQ treatment group (26.57 ± 10.35 days vs. 19.10 ± 7.80 days, P = 0.020). There were 3 patients deceased during inpatient period, two patients were with HCQ/CQ treatment (P = 0.551). In the multivariate linear regression analysis, disease durations at admission (t = 3.643, P = 0.001) and HCQ/CQ treatment (t = 2.637, P = 0.013) were independent parameters for patients' VSPs. One patient with CQ had recurrent first-degree atrioventricular block (AVB) and obvious QTc elongation, another one complained about dizziness and blurred vision which disappeared after CQ discontinuation. One patient with HCQ had transient AVB. CONCLUSIONS: In summary, we identify that the HCQ/CQ administration is not related to less mortality cases at later phase of COVID-19. More studies are needed to explore whether HCQ/CQ treatment would lead to SARS-Cov-2 RNA clearance delay or not.

AIM: The European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) algorithm for the management of knee osteoarthritis (OA) is available worldwide from 2014, but in 2019 an update was published. Based on this algorithm, a Working Group (WG), including ESCEO members and Chinese experts, wished to see how the new ESCEO algorithm was perceived by Chinese experts in knee OA and how it was integrated into their clinical practice. METHODS: A WG was held between members of the international ESCEO task force and a group of Chinese experts. RESULTS: Non-pharmacological approach should be combined with pharmacological interventions. In step 1, symptomatic slow-acting drugs for osteoarthritis (SYSADOA) are the most important background drugs. Evidence, supported by high-quality research, is available only for crystalline glucosamine sulfate (pCGS) and chondroitin sulfate. Topical NSAIDs could be used as an additional option. In step 2, oral NSAIDs could be useful, but cardiovascular/renal/gastrointestinal profiles of the patients should be considered. Intra-articular hyaluronic acid and corticosteroids are alternative to oral NSAIDs, but the evidence is still limited. If steps 1 and 2 are not sufficient, weak opioids could be used. Overall, the conclusions of the ESCEO algorithm are accepted in China for products available in this country. The WG suggests the importance of economic studies, specifically made in China. CONCLUSION: This work provides evidence-based advice to establish a treatment algorithm in knee OA, for practical implementation in clinical practice in China.

CONTEXT: Rheumatoid arthritis (RA) is a chronic multisystem autoimmune disease, mainly characterized by synovitis and with symmetrical joint involvement. LCAP therapy for RA patients has been shown to be safe and efficacious in some developed countries for over a decade. OBJECTIVE: The study intended to evaluate the efficacy and safety of leukocytopheresis (LCAP) for treatment of rheumatoid arthritis (RA) and to study the influence of treatment on the levels of various serum cytokines. DESIGN: The study was a nonblinded, nonrandomized, controlled trial. SETTING: The study took place in the Department of Rheumatology and Immunology at Beijing Hospital at the National Center of Gerontology in Beijing, China. PARTICIPANTS: Participants were 51 patients with RA at the hospital with a 28-joint disease activity score (DAS28) exceeding the 3.20 needed to fulfill the classification criteria of the American College of Rheumatology (ACR). INTERVENTION: Participants were divided into 2 groups. One group (intervention group) received LCAP therapy (n = 20), while the control group (n = 31) received disease-modifying antirheumatic drugs (DMARDs). Patients receiving the LCAP therapy were treated using a Cellsorba column every 5 days for a total of 5 treatments. OUTCOME MEASURES: Clinical assessment of participants' symptoms included: (1) a tender-joint count, (2) a swollen-joint count, (3) erythrocyte sedimentation rates (ESR), (4) C-reactive protein levels (CRP), (5) a visual analog scale (VAS) for pain, (6) the DAS28 C-reactive protein (DAS28-CRP) scores, and the Health Assessment Questionnaire Disability Index (HAQ-DI). The study also evaluated participants' scores for the American College of Rheumatology (ACR) Core Data Set. Serum collected before and after therapy from both groups was analyzed for the levels of bradykinin, serotonin, heat shock protein 70, human CXC-chemokine ligand 16 (CXCL16), prostaglandin E2, and macrophage inflammation protein 1α. RESULTS: At week 4 for participants receiving the LCAP therapy, ACR20, ACR50, and ACR70 were observed in 55%, 30%, and 20% of patients, respectively, compared to 19.4%, 3.2%, and 0% for patients in the control group (P < .05). Also, at week 24 of LCAP therapy, ACR20, ACR50, and ACR70 were observed in 70%, 50%, and 30% of patients, respectively, which was significantly higher than the 25.8%, 12.9%, and 3.2% of patients in the control group (P < .05). The serum levels of CXCL16 and serotonin were significantly reduced in the LCAP group compared with control group. CONCLUSIONS: This study indicated that LCAP therapy can significantly decrease RA disease activity and is a safe and effective alternative therapy. LCAP therapy significantly reduced serum CXCL16 and serotonin levels, offering a putative mechanism by which it improves the articular symptoms of RA.

OBJECTIVES: This study aimed to examine the associations between family history and clinical manifestations and immunologic characteristics of lupus in China. METHODS: Based on their family history, lupus patients from the Chinese lupus treatment and research group (CSTAR) registry were categorised: familial lupus (FL), family history of other rheumatic disorders (RD), and sporadic lupus (SL). Demographic data, clinical manifestations, and laboratory data were compared among these three groups. RESULTS: A total of 2,104 patients from CSTAR were included, with 34 (1.6%) in the FL group, 50 (2.4%) in the RD group, and 2,020 (96.0%) in the SL group. There were no significant differences in age or gender among these groups (p=0.36 and p=0.75, respectively). The prevalence of discoid rash and positivity of anti-RNP antibodies differed significantly among the three groups. Photosensitivity and neurological disorder were marginally significantly different among the three groups (p=0.05). No statistical differences were observed in other clinical manifestations or laboratory results. In the FL group, first-degree relatives (25/34, 73.5%) had higher susceptibility to lupus. Rheumatoid arthritis (RA) (35/50, 70.0%) was the most frequent non-lupus rheumatic disorder in the RD group. CONCLUSIONS: Among lupus patients, the rate of familial lupus was lower in Chinese patients than among other ethnicities. Familial lupus cases are found mainly among their first-degree relatives. A family history of lupus did not significantly affect clinical phenotypes, except for higher frequency of discoid rash and anti-RNP in the FL group, and more anti-RNP positivity in the RD group.

OBJECTIVE: To evaluate the effects of a multitarget method involving plasmapheresis therapy combined with tumor necrosis factor (TNF)-α inhibitor and disease-modifying antirheumatic drugs (DMARDs) on disease activity parameters in the treatment of active rheumatoid arthritis (RA). METHODS: Sixty-five patients with active RA were divided into two groups according to the treatment administered: the plasmapheresis combination therapy group (Plasmapheresis combination group; 38 cases), in which patients received plasmapheresis therapy along with a TNF-α inhibitor (recombinant human tumor necrosis factor-Fc; rhTNFR:Fc; Etanercept biosimilars) and DMARDs, and a TNF-α inhibitor therapy group (biological agent group; 27 cases), in which patients received a TNF-α inhibitor and DMARDs. Clinical parameters were measured before and at 4 and 24 weeks after treatment. RESULTS: ACR20, ACR50, and ACR70 responses at week 4 were achieved in 84.2%, 78.9%, and 60.5% of the patients in the plasmapheresis combination group, respectively, and 74.1%, 55.6%, and 29.6% of the patients in the biological agent group, respectively. The ACR50 and ACR70 response rates were superior in the former than the latter group (p < 0.05). Similar patterns of statistical significance were observed for ACR20, ACR50, and ACR70 responses at week 24 after the treatment. ACR50 responses were achieved in 84.2% patients and ACR70 responses were achieved in 76.3% patients in the plasmapheresis combination group, and these proportions were better than those in the biological agent group (p < 0.05). CONCLUSIONS: The multitarget method combining plasmapheresis, TNF-α inhibitor, and DMARDs for RA therapy was superior to the combination of TNF-α inhibitor for reducing disease activity parameters in patients with active RA.

Systemic lupus erythematosus (SLE) is an autoimmune disease with heterogeneous organ and system manifestations. In this study, urinary metabolic alterations related to SLE were investigated by performing gas chromatography/mass spectrometry (GC/MS) based metabolomics and multivariate statistical analysis. Patients with SLE and healthy controls could be clearly differentiated in view of the metabolic abnormity in urine. Among 70 identified endogenous metabolites, 23 metabolites were dramatically increased in SLE patients, which involved in several key metabolic pathways including energy metabolism, nucleotide metabolism, oxidative stress and gut-microbiome-derived metabolism. This noninvasive and GC/MS-based metabolomic technique is a promising and potent strategy for identifying novel biomarkers and understanding pathogenesis of SLE.

OBJECTIVES: The aim of this study is to characterize the serum metabolic profiles of patients with systemic lupus erythematosus (SLE) using metabolomics. METHODS: Serum samples were collected from patients with SLE (n = 80) and gender- and age-matched healthy controls (n = 57). Metabolite profiles were performed with gas chromatography-mass spectrometry in conjunction with multivariate statistical analysis, and possible biomarker metabolites were identified. RESULTS: SLE and disease severity-related metabolic phenotypes were identified in sera. Parameters of the metabolomic model were correlated with SLEDAI (SLE disease activity index) scores in SLE. The metabolic signature of SLE patients comprised metabolite changes associated with amino acid turnover or protein biosynthesis, saccharometabolism, lipid metabolism, and gut microbial metabolism. Disease activity-related alterations included glutamate, 2-hydroxyisobutyrate, citrate, glycerol, linoleic acid, and propylparaben metabolites. Parts of endogenous metabolites related to SLE had the relationship with serum immunological parameters and organ manifestations. Moreover, receiver operating characteristic curve analysis revealed a higher diagnosis accuracy of endogenous metabolites. CONCLUSIONS: Our study distinguished serum metabotypes associated with SLE and disease activities. The implementation of this metabolomic strategy may help to develop biochemical insight into the metabolic alterations in SLE.

OBJECTIVE: To evaluate the impact of RA on work capacity and identify factors related to work capacity impairment in patients with RA. METHODS: A cross-sectional multicentre study was performed in 21 tertiary care hospitals across China. A consecutive sample of 846 patients with RA was recruited, of which 589 patients of working age at disease onset constituted the study population. Information on the socio-demographic, clinical, working and financial conditions of the patients was collected. Logistic regression analyses were used to identify factors associated with work capacity impairment. RESULTS: The rate of work capacity impairment was 48.0% in RA patients with a mean disease duration of 60 months (interquartile range 14-134 months), including 11.7% leaving the labour force early, 33.6% working reduced hours and 2.7% changing job. Multivariable logistic regression analysis showed that reduced working hours was significantly related to current smoking [odds ratio (OR) 2.07 (95% CI 1.08, 3.97)], no insurance [OR 1.94 (95% CI 1.20, 3.12)], in manual labour [OR 2.66 (95% CI 1.68, 4.20)] and higher HAQ score [OR 2.22 (95% CI 1.36, 3.60)]. There was an association of current smoking [OR 3.75 (95% CI 1.54, 9.15)], in manual labour [OR 2.33 (95% CI 1.17, 4.64)], longer disease duration [OR 1.01 (95% CI 1.00, 1.01)] and lower BMI [OR 0.90 (95% CI 0.82, 0.99)] with leaving the labour force early. CONCLUSION: There is a substantial impact of RA on the work capacity of patients in China. Social-demographic, disease- and work-related factors are all associated with work capacity impairment.

Objective: Osteoarthritis (OA) is a commonly known prevalent joint disease, with limited therapeutic methods. This study aimed to investigate the expression of plasma microRNA-320c (miR-320c) in patients with knee OA and to explore the clinical value and potential mechanism of miR-320c in knee OA. Methods: Forty knee OA patients and 20 healthy controls were enrolled. The levels of plasma miR-320c and plasma inflammatory cytokines were measured by real-time PCR or ELISA. Correlations of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores and cytokine levels with the miR-320c expression level were evaluated by Pearson correlation analysis. Then, a receiver operating characteristic (ROC) curve was drawn to analyse the diagnostic value of miR-320c in OA. Finally, the interaction of miR-320c and cAMP responsive element binding protein 5 (CREB5) was determined using a luciferase reporter assay, and the effect of CREB5 on the cAMP pathway was assessed. Results: The expression level of plasma miR-320c was significantly higher in OA patients than in healthy controls (p < 0.05). The increased plasma miR-320c level was positively correlated with the WOMAC score (r = 0.796, p < 0.001) and the plasma interleukin (IL)-1ß (r = 0.814, p < 0.001) and IL-6 (r = 0.695, p < 0.001) levels in patients with OA. ROC curve analysis demonstrated the relatively high diagnostic accuracy of plasma miR-320c for OA. Furthermore, the luciferase reporter assay results showed that miR-320c regulates CREB5 expression by binding to the CREB5 3'-untranslated region. Moreover, suppression of CREB5 significantly reduced the expression levels of c-fos and c-jun. Conclusion: Our results indicate that plasma miR-320c may serve as a potential novel predictor of the severity of knee OA and that miR-320c may play an important role in the pathogenesis of OA through inhibiting the cAMP pathway by targeting CREB5.

INTRODUCTION: Ixekizumab, an interleukin-17A inhibitor, was efficacious and well tolerated for the treatment of active radiographic axial spondyloarthritis (r-axSpA) in international clinical studies. This phase III study aimed to determine the efficacy and safety of ixekizumab for treating Chinese patients with active r-axSpA. METHODS: Adults with active r-axSpA naïve to biologic disease-modifying antirheumatic drugs (bDMARDs), or with an inadequate response/intolerance to one tumor necrosis factor inhibitor, were randomized (1:1), double-blind, to receive ixekizumab 80 mg every 4 weeks (IXEQ4W; starting dose 160 mg), or placebo, for 16 weeks. Patients receiving placebo were then switched to IXEQ4W, and those receiving IXEQ4W continued, until week 52. The primary endpoint was the proportion of bDMARD-naïve patients achieving an Assessment of SpondyloArthritis International Society 40 (ASAS40) response at week 16. RESULTS: In total, 147 patients were randomized to receive placebo (n = 73) or IXEQ4W (n = 74). At week 16, more bDMARD-naive patients achieved ASAS40 in the IXEQ4W group (n = 66; 40.9%) than the placebo group (n = 64, 7.8%; p < 0.001). In the overall study population, ASAS40 was also achieved by more patients in the IXEQ4W group (37.8%) than the placebo group (8.2%; p < 0.001) at week 16, with a significant difference observed as early as week 1. There were significant improvements in all key secondary endpoints at week 16 with IXEQ4W versus placebo. Efficacy was sustained at week 52 in patients who continued IXEQ4W and there were also clinical improvements from weeks 16 to 52 in patients switched to IXEQ4W. The safety profile of ixekizumab was consistent with that described previously. Infections and injection-site reactions were the most frequently reported events of special interest. CONCLUSIONS: IXEQ4W was associated with rapid and significant improvements in the signs and symptoms of active r-axSpA in Chinese patients at week 16 that were sustained at week 52, with no new safety signals. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov identifier: NCT04285229.

(1) Background: Topical non-steroidal anti-inflammatory drugs (NSAIDs) are one of the primary drugs for treating musculoskeletal pain. However, there are currently no evidence-based recommendations about drug selection, drug administration, drug interactions, and use in special populations or other pharmacology-related content of such medications. To this end, the Chinese Pharmaceutical Association Hospital Pharmacy Professional Committee developed multidisciplinary guidelines on using topical NSAIDs to treat musculoskeletal pain. (2) Methods: The guidelines development process followed the World Health Organization guideline development handbook, the GRADE methodology, and the statement of Reporting Items for Practice Guidelines in Healthcare. The guideline panel used the Delphi method to identify six clinical questions to be addressed in the guidelines. An independent systematic review team conducted a systematic search and integration of evidence. (3) Results: Based on the balance between the benefits and harms of an intervention, the quality of the evidence, patient preferences and values, and resource utilization, the guideline panel developed 11 recommendations and nine expert consensuses on using topical NSAIDs to treat acute and chronic musculoskeletal pain. (4) Conclusions: Based on the effectiveness and overall safety of topical NSAIDs, we recommend patients with musculoskeletal pain use topical NSAIDs and suggest high-risk patients use topical NSAIDs, such as those with other diseases or receiving other concurrent treatments. The evidenced-based guidelines on topical NSAIDs for musculoskeletal pain incorporated a pharmacist perspective. The guidelines have the potential to facilitate the rational use of topical NSAIDs. The guideline panel will monitor the relevant evidence and update the recommendations accordingly.
RESUMEN
OBJECTIVE: To learn about the prevalence and risk factors of coronary artery disease (CAD) in rheumatoid arthritis (RA). METHODS: Data were obtained from a 12-month retrospective investigation of the patients with RA, randomly selected from Departments of Rheumatology and Immunology in 21 big hospitals in China. The data were collected about their social conditions, clinical conditions, medications associated with RA, such as disease modifying anti-rheumatic drugs (DMARDs), non steroidal anti-inflammatory drugs (NSAIDs), glucocorticoid, biologic agents. A nonparameter test and multivariate logistic regression analysis were performed. RESULTS: In the study, 960 patients were enrolled. The prevalence of CAD was 3.5% in China, which was obviously higher than that of normal people. The prevalence of overweight and obesity, smoking, hypertension, diabetes mellitus, hypercholesterolemia and cerebrovascular disease were 35.1%, 12.3%, 17.0%, 7.7%, 0.4% and 3.0%, respectively. Compared with the control group, the CAD group had higher age [(64.7±9.3) years vs. (52.3±14.0) years,P<0.001], more rheumatoid nodules (14.7% vs. 3.1%,P=0.005), lower rate of hydroxychloroquine (HCQ) use (5.9% vs. 22.6%,P=0.021), higher prevalence rates of lung interstitial disease (17.5% vs. 7.0%,P<0.001), diabetes mellitus and hypertension (29.4% vs. 7.0%,P<0.001; 38.2% vs. 16.2%,P=0.001). There was no obvious correlation of CAD in RA with joint deformity, rheumatoid factor (RF) titer, glucocorticoid use, hypercholesterolemia and body mass index (BMI). Multivariate analysis showed higher age, diabetes mellitus and hypertension were independent predictors of CAD, and the use of HCQ was a protective factor of CAD. CONCLUSION: The prevalence of CAD is 3.5%. Higher age, diabetes mellitus and hypertension are independent predictors of CAD, and the use of HCQ is a protective factor of CAD.

OBJECTIVE: To investigate the current status of tumor necrosis factor (TNF) inhibitors application in rheumatoid arthritis (RA) patients in China and to analyze the related factors. METHODS: A retrospective survey was conducted in 21 hospitals from different parts of China. The patients with RA were randomly enrolled. Data of their social backgrounds, clinical conditions, usage and adverse effects of TNF inhibitors were collected. The costs of TNF inhibitors and the indirect costs of the disease were calculated. A multivariate Logistic regression analysis was performed to analyze the factors related to TNF inhibitors application. RESULTS: In the study, 1 095 RA patients from July 2009 to November 2010 were enrolled, of whom 112 had received TNF inhibitors, representing 10.2% of the total patients. The patients who received etanercept and infliximab were 7.4% (86/1 095) of the patients and 2.4% (26/1 095), respectively. There were 0.5% of the patients (5/1 095) who had received both of the TNF inhibitors. The patients who had accepted etanercept and treatment duration for less than 3 months and 3-6 months accounted for 38.5% and 25.0% respectively, while those treated with Infliximab were 38.1%. Their health assessment questionnaire (HAQ) scores were 1.1, 0.5 and 0.1, corresponding to treatment duration of infliximab for less than 3, 3-6 and 6-9 months and those were 1.3, 1.0, 0.3 corresponding to treatment duration of etanercept, respectively. Infliximab costs were RMB 24 525.0, 69 300.0 and 96 800.0 Yuan and etanercept costs were RMB 7 394.8, 9 158.6, 54 910.9 Yuan, respectively. Indirect costs for RA patients who accepted infliximab for less than 3, 3-6 and 6-9 months were RMB 365.6, 0 and 158.9 Yuan and those who accepted etanercept were RMB 2 158.4, 288.5 and 180.1 Yuan, respectively. Allergy and infection were the main side-effects of etanercept and both happened in 3.5% of all the patients. Liver damage happened in 2.3% of all the patients, while allergy and infection happened in 6.5% of all the patients who accepted infliximab. Logistic regression analysis showed that patients with higher education experience increased the odds of entering the TNF inhibitors group (OR: 1.292, 95%CI: 1.132-1.473, P=0.000). CONCLUSION: About one-tenth of RA patients in China have accepted TNF inhibitors. Higher education experience is the key factor for using TNF inhibitors.

OBJECTIVE: To investigate the medication status of rheumatoid arthritis (RA) patients and to analyze the clinical use of sulphasalazine (SSZ) and the adverse effect. METHODS: A total of 1 096 outpatients and inpatients diagnosed with RA were investigated in 21 hospitals all over China from July 2009 to December 2010, including gender, age of onset, clinical manifestations, as well as the clinical characteristics and medication status of 160 RA patients who received SSZ therapy. RESULTS: In the group of 160 patients who received SSZ, the male-to-female ratio was 1:7, The average age at onset was (46.1±15.0) years, while the average course was (9.9±7.8) years. The average dose of sulphasalazine was (1.87±0.52) g/d for a mean duration of (26.3± 14.6) months. Only 17% (27/160) of the patients received SSZ monotherapy. Methotrexate (63.1%), leflunomide (36.2%) and hydroxychloroquine (18.1%) were most commonly used combination drugs. And 36.2% (58/160) of the patients used the two-drug combination of methotrexate plus sulphasalazine .In this group, 41.9% (67/160) once used SSZ but withdrew for adverse events and other reasons, while 17.5% (28/160) withdrew for adverse events, of which the most common were gastrointestinal (8.8%), skin (3.8%) and liver toxicity (3.1%). CONCLUSION: Sulphaszlazine is not a common choice in the RA therapeutics in China, and the average dose of SSZ is lower than the standard dose of 2 to 3 g/d . The adverse events of SSZ are common; however, there are few severe adverse events or threat to life,SSZ is relatively safe in clinical practice.

OBJECTIVE: The equivalence of the biosimilar HS016 to adalimumab (Humira) for the treatment of active ankylosing spondylitis (AS) patients has been previously validated. The aim was to compare the efficacy of HS016 and adalimumab in stratified subgroups at different time points using Health Assessment Questionnaire for Spondyloarthropathies (HAQ-S) and short form 36 (SF-36) questionnaires. METHODS: We carried out a multicenter, randomized, double-blind, parallel, positive control, phase 3 trial of patients with active AS. They were selected randomly to be subcutaneously administered 40 mg HS016 or adalimumab every 2 weeks for a total treatment period of 24 weeks in a 2:1 ratio. A health surveys were used to assess mental and physical improvements of patients as well as other factors. RESULTS: HAQ-S revealed that changes in scores from baseline in both groups were time dependent until 14 weeks and that during the first 4 weeks of treatment the changes declined rapidly. The SF-36 health survey revealed that both HS016 and adalimumab produced rapid beneficial effects against AS during the first 2 weeks of therapy, which gradually declined between 2 and 12 weeks and flattened out after 12 weeks until 24 weeks. CONCLUSION: This trial demonstrated that both HS016 and adalimumab produced rapid improvements in symptoms during the first 2 weeks of treatment. These findings suggest that HS016 is an alternative economical treatment for Chinese AS patients producing a rapid amelioration of symptoms, aiding them to recover their lifestyle satisfaction. TRIAL REGISTRATION: http://www.chictr.org.cn/enindex.aspx , ChiCTR1900022520, retrospectively registered. Key points ⢠HS016 and adalimumab produced rapid AS symptom improvements during the first 2 weeks followed by a slowdown of improvements until week 4 with afterwards few improvements evaluated by HAQ-S ⢠The improvements according to the short form of the 36 (SF-36) questionnaires revealed similar trends as for HAQ-S ⢠There was no significant difference in HAQ-S and SF-36 scores between HS016 and adalimumab.

OBJECTIVE: To investigate the effects of 5-Aza-CdR (methylation transferase inhibitor)on the expression levels of leptin gene in chondrocytes and methylation states of leptin promoter region between osteoarthritis (OA) group and control. METHODS: The chondrocytes in osteoarthritis group were treated with 5-Aza-CdR with different doses and time-points, and the expression level of leptin was detected by real-time polymerase chain reaction for picking up the optimum dose and time-point. Next, the chondrocytes in 5 osteoarthritis patients and 5 control patients (amputation due to severe trauma) were treated with 5-Aza-CdR. Lastly, leptin mRNA expression levels in the four groups osteoarthritis and control chondrocytes treated with/without 5-Aza-CdR were measured by real-time PCR and the methylation state of promoter region (-280 - +79) was detected by epitope quantitative DNA methylation analysis. RESULTS: (1) After treating the chondrocytes in OA groups with 10 µmol/L 5-Aza-CdR for 72 h, the mRNA expression levels of leptin were increased significantly. (2) The mRNA expression levels of leptin were significantly different among the four groups (P < 0.05), and the chondrocytes in osteoarthritis groups treated with 5-Aza-CdR showed a marked induction of leptin mRNA expression. (3) Analysis of quantitative methylation data using an unsupervised hierarchical clustering algorithm, showed that methylation patterns of leptin promoter was different between control and osteoarthritis chondrocyte treated with/without 5-Aza-CdR. CONCLUSION: Demethylation of leptin promoter might up-regulate leptin gene expression level and it might contribute to osteoarthritis.

Lymphotoxin-alpha (LTA) gene has been reported to have a genetic association with systemic lupus erythematosus (SLE), psoriasis, and rheumatoid arthritis. However, the association of LTA with ankylosing spondylitis (AS) has not reported. By case-control study, we carried out the high density limited genome scanning to the HLA class III region about 58 kb in Ningxia population (case 300 and control 385). In this study, 33 SNPs in LTA were genotyped in Ningxia population. We analyzed these SNPs and the haplotypes covering LTA. Only the distribution of TCC haplotype which contains mutation allele of LTA rs909253 was statistically significant(P=0.0005). The C allele frequency of the LTA rs909253 T/C polymorphism was higher in AS cases than that in the controls (28.5% versus 19.7%, P=2×10-4) in Ningxia population. The results suggest that there is a relevance between LTA and the susceptibility of AS, and we identified that the LTA polymorphism may be associated with AS in Ningxia population.

Objective: To enable physicians to understand the efficacy and safety of Tocilizumab (TCZ) in patients with severe coronavirus disease-2019 (COVID-19). Methods: We respectively reviewed the clinical records, laboratory results, and chest computed tomography (CT) scans of 5 geriatric patients with severe COVID-19 treated with TCZ during their inpatient hospitalization period in Wuhan from February 08, 2020 to April 04, 2020. The survival status of the patients in the third and the sixth month after being discharged was followed up and recorded. Results: On the fourteenth day after TCZ administration, periphery oxygen saturation rate (SpO2) returned to normal in 4 patients. The serum Interleukin-6 (IL-6) levels altered in five patients after TCZ infusion. One patient rapidly progressed to acute respiratory distress syndrome (ARDS) and died of multiple organ failures eventually. The other 4 patients were cured and discharged from the hospital. During the inpatient hospitalization period, two patients suffered from virus shedding periods (VSPs) delay, and one patient had mild upper respiratory tract infection. One patient died of esophageal carcinoma one month after being discharged. The other 3 patients survived despite mild cough and insomnia. Serum-specific IgG type antibody titer was decreased in one patient. Six months after being discharged, the other three patients were in good condition. Conclusion: TCZ may be an efficient therapeutic option for patients with COVID-19. However, the possibility of VSPs delay, secondary infection, serum protective antibody tilter attenuation, and long-term survival status should be addressed before TCZ therapy initiation.
