ObjectiveTo investigate the efficacy and safety of recombinant human tumor necrosis factor-α receptor Ⅱ:IgG Fc fusion protein (rhTNFR:Fc) for treatment of active rheumatoid arthritis (RA). MethodsThis study included 86 patients with active rheumatoid arthritis treated between September 2011 and January 2013. They were divided into two groups randomly. Forty-three patients in the treatment group received rhTNFR:Fc (25 mg, twice a week) by subcutaneous injection and methotrexate (MTX) (10 mg, orally once a week), and the other 43 patients in the contrast group received MTX (10 mg, orally once a week), hydroxychloroquine (100 mg, orally twice daily), and leflunomide (10 mg, orally once daily). The clinical efficacy of the treatments 12 weeks later were compared between the two groups. American College of Rheumatology (ACR) 20, 50, and 70 evaluation criteria were used for efficacy evaluation. ResultsThe ACR 20, 50 and 70 effective rates in 4, 8 and 12 weeks after the treatment in the treatment group were significantly higher than those in the control group (P<0.05). The seven indicators including the duration of morning stiffness, joint tenderness index, joint swelling index, erythrocyte sedimentation rate, C-reactive protein, platelets and rheumatoid factors within 12 weeks after treatment were significantly improved in both the two groups, and the improvements in the treatment group were more significant (P<0.05). There was no significant difference in the incidence of adverse drug reactions between the two groups (P>0.05). ConclusionRhTNFR:Fc is effecive and safe in treating active RA.
ObjectiveTo review the role of dendritic cells (DC) in immune metabolism of rheumatoid arthritis (RA). MethodsLiterature on the role of DC in the immune metabolism of RA was extensively reviewed in recent years, and the metabolic characteristics of RA, the role of DC in RA, the correlation between the immune metabolism of DC and pathogenesis of RA, and the treatment were summarized and analyzed. Results DC promotes the progression of RA under hypoxia, increased glycolysis, inhibition of oxidative phosphorylation, and decreased lipid metabolism. Moreover, many DCs (especially conventional DC and monocyte-derived DC) have different functions and phenotypic characteristics in RA, which are closely related to the occurrence and development of RA. Conclusion DC plays an important role in the immune metabolism of RA, and immunometabolism therapy based on DC can provide targeted therapy for the treatment of RA.
Objective To analyse the results of posterior cruciate l igament-retained mobile-bearing total knee arthroplasty (TKA) in treatment of rheumatoid arthritis (RA) and to solve the problems often encountered during surgery. Methods From February 1999 to August 2005, the cl inical data from 73 patients with RA undergoing TKA were analysed retrospectively. In 73 patients, 38 patients were treated with posterior cruciate l igament-retained mobile-bearing prosthesis (group A), while 35 patients were treated with posterior stabil ized fixed-bearing prosthesis (group B). Another 70 patients with osteoarthritis (OA) treated with an posterior cruciate l igament-retained mobile-bearing prosthesis served as controls (group C). In group A, there were 8 males and 30 females with an average age of 56.5 years and an average diseasecourse of 16.8 years. In group B, there were 6 males and 29 females with an average age of 57.3 years and an average disease course of 17.1 years. In group C, there were 37 males and 33 females with an average age of 65.4 years and an average disease course of 10.8 years. There was no significant difference (P gt; 0.05) in general data between groups A and B, but there were significant differences (P lt; 0.05) when compared with group C. Results In groups A and B, 2 cases (5.3%) and 1 case (2.9%) had poor heal ing of incision, respectively; in group C, all cases had good heal ing of incision. There were significant differences in heal ing rate of incision between groups A, B and group C (P lt; 0.05). All patients were followed up 7.6 years on average (range, 3.5-10.5 years). Deep infection occurred in 1 case respectively in 3 groups, showing no significant difference (P gt; 0.05). Posterior instabil ity occurred in 1 case (2.6%) 5 years after operation in group A and 2 cases (2.9%) 9 years after operation in group C, and no posterior instabil ity occurred in group B; showing significant differences between groups A, C and group B (P lt; 0.05). There were significant differences (P lt; 0.05) in knee score, Feller patellar score, and anterior knee pain score between pre- and postoperative values among groups A, B, and C. There were significant differences (P lt; 0.05) in the function scores between pre- and post-operative values in 3 groups, between groups A, B and group C pre- and post-operatively. Conclusion Posterior cruciate l igament-retained mobile-bearing TKA can yield satisfactory cl inical results in treatment of RA at intermediate-term followup. This mobile-bearing prosthesis has a low prevalence of posterior instabil ity and a good outcome for anterior knee function without patellar resurfacing.
ObjectiveTo observe and study the clinical effect of glucosamine in the treatment of patients with knee articular cartilage injury caused by rheumatoid arthritis. MethodsForty-six patients with knee articular cartilage injury caused by rheumatoid arthritis treated from January 2013 to June 2015 were selected as the research subjects, and they were randomly divided into control group (conventional treatment group, n=23) and observation group (conventional and glucosamine treatment group, n=23) . Then the Noyes classification and serum articular cartilage injury related indexes [cartilage oligomeric matrix protein (COMP), matrix metalloproteinase (MMP)-1, MMP-3 and mouse tissue inhibitors of metalloproteinase (TIMP)-1], inflammatory indexes [tumor necrosis factor (TNF)-α, interleukin (IL)- 17 and IL-33] of the two groups before and after treatment were compared. ResultsIn the observation group, after treatment for 4, 8 and 12 weeks, Noyes grade was better than that in the control group, but with no statistical significance (P ＞ 0.05) . In the observation group, after treatment for 4, 8 and 12 weeks, serum inflammatory markers serum COMP, MMP-1, MMP-3 and TIMP-1 and other related indicators of cartilage damage and serum TNF-α, IL-17 and IL-33 were all significantly lower than those in the control group (P ＜ 0.05) . ConclusionIn the treatment of patients with knee articular cartilage injury caused by rheumatoid arthritis, glucosamine has active role for the improvement of articular cartilage injury and inflammatory stress state of patients.
Objective To explore the technique of the soft tissue balancing in the total knee arthroplasty (TKA) for the patients of rheumatoid arthritis with flexion contracture. Methods From November 1997 to May 2006, 38 patients with rheumatoid arthritis with flexion contracture underwent primary bilateral TKA and balancing of the soft tissues, among whomthere were 8 males and 30 females, aged 48-71 years old (58.2 on average). The course of disease was 28 months-16 years (7.6 years on average). The preoperative flexion contracture was (38.2 ± 11.3)°. The average range of motion (ROM) and HSS score were (49.1 ± 17.8)° and 23.9 ± 16.9, respectively. According to the preoperative flexion-contracture degree of the knees, these patients were divided into 3 levels: 5 patients with ≤ 20°, 26 patients with 20-60° and 7 patients with ≥ 60°. During the TKA procedure, based on the correct osteotomy, different methods of soft tissue balancing were used for different degrees of flexion contracture. The TKA soft tissue treatment was summed up as the releasing of posterior structures and the balancing between medial collateral ligaments (MCL) and lateral collateral ligaments (LCL), etc. Results The flexion contractures in 38 cases were all improved after the operation, among which 33 patients had a complete correction and only 5 patients had a residual flexion contracture of 5-10°. Eight knees suffered from complications within 1 week after operation, among which 3 had subcutaneous superficial infection and 5 had deep vein thrombus (DVT). These patients obtained good heal ing after active treatment. All the 38 patients were followedup for 10 months to 8 years with the median time of 37 months. The postoperative flexion deformity declined to (2.4 ± 5.7)°, and the ROM and HSS scores were (96.3 ± 14.6)° and 81.7 ± 10.4, respectively. There was statistical difference (P lt; 0.05). According to the HSS score, 27 patients (71.05%)were rated as excellent, 6 good (15.79%) and 5 fair (13.16%), and the choiceness rate was 86.84%. Conclusion The balancing of the soft tissue is a major treatment for correction of the flexion contracture, which can avoid bone over-resection during the surgery of TKA. The proper balancing of the soft tissue can not only achieve an obvious correction of the flexion contracture but also effectively improve the range of motion and the functional recovery of the knee joint after TKA.
Objective To evaluate the efficacy and safety of adalimumab for rheumatoid arthritis failing to respond to disease-modifying anti-rheumatic drugs (DMARDs). Methods The Cochrane Library, PubMed, EMbase, CBM, CNKI, VIP and Wanfang (from the date of their establishments to June 2010) were searched, and journals of relevant fields were retrieved to identify randomized controlled trials (RCTs). The data were analyzed by using RevMan 5.0 software. Results Four RCTs were included, all of which were from abroad and with good methodological quality. The baseline data of each trial were comparable. Meta-analyses showed that there was a significant difference between the adalimumab and the placebo in terms of ACR20, ACR50, ACR70, tender joint count, swollen joint count, patient assessment of pain, patient global assessment of disease activity, doctor global assessment of disease activity, and disability index of the HAQ. There was no difference between the adalimumab and the placebo in terms of serious adverse events, intractable adverse events and serious infection. Conclusion Adalimumab can treat rheumatoid arthritis failing to respond to DMARDs, but clinically the doctor should balance the benefit and the risk of the adalimumab.
Objective To study the risk factors of developing progressive pulmonary fibrosis (PPF) within one year in patients diagnosed with rheumatoid arthritis-associated interstitial lung disease (RA-ILD), and develop a nomogram. Methods A retrospective study was conducted in 145 cases of RA-ILD patients diagnosed and followed up in the Affiliated Hospital of Qingdao University from January 2010 to October 2022. Among them, 106 patients and 39 patients were randomly assigned to a training group and a verification group. The independent predictors of PPF in patients with RA-ILD within one year were determined by univariate and multivariate logistic regression analysis. Then a nomogram is established through these independent predictive variables. Calibration curve, Hosmer-Lemeshow test, receiver operating characteristic (ROC) curve and area under ROC curve (AUC) and clinical decision curve were used to evaluate the predictive efficiency of the nomogram model for PPF in RA-ILD patients within one year. Finally, internal validation was used to test the stability of the model. Results Of the 145 patients with RA-ILD, 62 (42.76%) developed PPF within one year, including 40 (37.7%) in the training group and 22 (56.41%) in the verification group. The PPF patients had higher proportion of subpleural abnormalities, higher visual score of fibrosis and shorter duration of RA. Logistic regression analysis showed that the duration of rheumatoid arthritis (RA), visual score of fibrosis and subpleural abnormality were independent risk factors for the occurrence of PPF within one year after diagnosis of RA-ILD. A nomogram was constructed based on these independent risk factors. The AUC values of the training group and the verification group were 0.798 (95%CI 0.713 - 0.882) and 0.822 (95%CI 0.678 - 0.967) respectively, indicating that the model had a good ability to distinguish. The clinical decision curve showed that the clinical benefit of PPF risk prediction model was greater when the risk threshold was between 0.06 and 0.71. Conclusion According to the duration of RA, the visual score of fibrosis and the presence of subpleural abnormalities, the predictive model of PPF was drawn to provide reference for the clinical prediction of PPF in patients with RA-ILD within one year after diagnosis.
ObjectiveTo investigate the potential causal relationship between four types of reproductive behaviors and rheumatoid arthritis (RA), with the goal of establishing a theoretical foundation for clinical prevention and treatment strategies. MethodsPooled gene-wide association study (GWAS) data were obtained from large publicly searchable databases. Four characteristics like menarche, menopause, the age of first pregnancy and the age of last pregnancy, which related to reproductive behavior were selected as the exposure factors and RA as the outcome factors. Single nucleotide polymorphisms (SNPs), which were strongly correlated with the phenotype of the exposure factors, were screened as the instrumental variables, and two-sample Mendelian randomization analyses were used to assess the potential causal relationship between the exposure and the disease. Results① The Mendelian randomization analysis utilizing the inverse variance weighted method on two distinct samples revealed a significant negative correlation between the age of first pregnancy and last pregnancy with the risk of RA (OR=0.91, 95%CI 0.85 to 0.98, P=0.011; OR=0.54, 95%CI 0.31 to 0.93, P=0.026). Conversely, no causal relationship was observed between menarche and menopause with RA. Sensitivity analysis confirmed the robustness of the causal relationship, while MR Egger intercept analysis did not identify any potential horizontal pleiotropy (Page of first gestation -RA=0.169, Page of last gestation -RA=0.283). ② Reverse Mendelian randomization analysis revealed a significant positive causal association between RA and the age of first pregnancy, while no causal relationship was observed with the age of last pregnancy (OR=1.07, 95%CI 1.02 to 1.11, P=0.001). ③ Multivariate Mendelian randomization analysis demonstrated that both the age of first pregnancy and last pregnancy in women were inversely associated with the risk of RA (OR=0.88, 95%CI 0.80 to 0.97, P=0.010; OR=0.68, 95%CI 0.48 to 0.97, P=0.033). ④ There existed a negative correlation between the age of pregnancy in women and the risk of developing RA, suggesting a potential protective effect. ConclusionPregnancy age may have a negative causal relationship with the risk of RA, while menarche and menopause have no causal relationship with RA.
ObjectiveTo evaluate the prevalence of interstitial lung disease (ILD) in patients with rheumatoid arthritis (RA),and explore the association of ILD with RA. MethodsPatients who were diagnosed as RA were recruited in the study,and were categorized into a RA-ILD group and a non-ILD group according to high-resolution computed tomography (HRCT).The data of clinical characteristics,serum biomarkers measurement,and pulmonary function test were collected. Logistic regression analysis was performed to evaluate the factors associated with the incidence of ILD in RA. ResultsA total of 59 patients with RA were enrolled. The incidence of ILD in RA was 42.3%. The rheumatoid factor (RF),carbohydrate antigen 15-3 (CA15-3),carbohydrate antigen12-5 (CA125),inspiratory capacity (IC) and diffusion capacity for carbon monoxide of the lung (DLCO) were significantly different between two groups (all P<0.05). Multivariate logistic regression analysis revealed that the increased CA15-3 and decreased DLCO were independent risk factors for ILD in the patients with RA. ConclusionsThe occurrence of ILD with RA seems very high. CA15-3 and DLCO may be important risk factors for the incidence of ILD in patients with RA.
