Patients with such complications can benefit from a low vision assessment to improve their functionality and their quality of life. In this case study, the importance of early detection and management of ocular complications of JRA, as well as visual rehabilitation through a low vision assessment, are highlighted and discussed. Case Presentation: A 12-year-old female of East Indian descent presented to the Low Vision Center of the University of the West Indies Optometry Eye Unit, bilaterally aphakic (absence of crystalline lens) as a result of complications she developed secondary to a systemic condition diagnosed as JRA. She presented with a distance visual acuity of 2.30 logMAR in the RE, and 1.64 logMAR in the LE, at near she was able to read 8.0 M and 3.2 M at a distance of 8 cm for RE & LE respectively. She has a history of ocular disorder secondary to JRA such as cataract, uveitis, upon low vision assessment a new spectacle prescription and an illuminated stand magnifier of 8D was issued, the patient was satisfied with the outcome of the treatment, management and low vision device issued. Conclusion: At the end of the low vision assessment, the patient was extremely satisfied and looked forward to the prospect of returning to school. Although JRA can have severe ocular complications, with the correct management, a patient’s quality of life can be dramatically improved thus stressing the importance of these types of visual assessments.展开更多

It is associated with abnormal levels of serum zinc (Zn) and copper (Cu) as during inflammation serum copper concentration increases and zinc decreases. Objective: To assess the serum Zn and Cu levels in different sub-types of JIA patients and their correlation with the disease duration. Methods: This cross-sectional study was conducted over twelve months at the Pediatric Rheumatology Division, Department of Paediatrics, Bangabandhu Sheikh Mujib Medical University. Sixty-nine JIA cases that fulfilled the International League of Association for Rheumatology (ILAR) criteria were taken as cases and age and sex-matched healthy children were considered as controls. The serum Zn and Cu tests were done using the spectrophotometric method with INDIKO PLUS Drug Analyzer. Data were recorded in a pre-designed questionnaire. Data were checked, verified and analyzed manually where continuous variables were analyzed using unpaired t-test and categorical variables using the ANOVA test. Pearson’s correlation coefficient test was used to see the correlation of serum zinc and copper levels with disease duration. Results: Boys were predominant in both case and control groups, with the majority within the 10 to 16-year-age group. Enthesitis-related arthritis (ERA) was the most common subtype followed by sJIA, Oligo JIA, Poly JIA (RF-) and unclassified subtypes. Disease duration was found less than 12 months in 30.4% of JIA patients. Serum analysis revealed a statistically significant reduction in mean zinc levels and increased copper levels in JIA patients compared to controls. This study observed a negative correlation between serum zinc levels and disease duration, whereas serum copper levels exhibited a positive correlation with disease duration. Conclusion: In conclusion, this study revealed that JIA patients exhibit alterations in serum zinc and copper levels. Serum copper levels showed a positive correlation and serum zinc levels showed a negative correlation with the duration of the disease.展开更多

In the era of biotherapies and the arrival of biosimilars in sub-Saharan Africa, the objective of this study was to describe plasma IL-6 variations in RA patients at Cité Verte District Hospital (Cameroon). Material and Methods: Descriptive and analytical cross-sectional study from December 1, 2021 to May 31, 2022. We included patients over 18 years old suffering from RA (ACR/EULAR 2010). Patients with an infection were not included. The data collected were age, sex, smoking status, family history, disease duration, disease activity by DAS28, CRP, rheumatoid factor, and plasma level of IL-6. Bone erosion was sought on radiography and ultrasound. Result: We included 31 patients, 25 of whom were women (80.6%). The mean age was 47.27 ± 17.97 years. Disease activity was predominantly moderate (32.3%) and severe (32.3%). Mean IL-6 level was 15.29 ± 2.36 pg/ml (extremes: 11.26 pg/ml and 20.15 pg/ml). IL-6 levels were higher in patients with a history of smoking. Similarly, IL-6 levels were higher in patients with mildly active RA in remission than in moderately and severely active RA. Mean IL-6 levels were significantly higher in patients with erosive RA (16.3 pg/ml VS 14.6 pg/ml). Conclusion: IL-6 levels were significantly elevated in men, weaned smokers and patients with bone erosions.展开更多

文摘Background: Juvenile Rheumatoid Arthritis (JRA) is an inflammatory disease that affects the joints of children and is associated with ocular complications, like uveitis and cataract. Patients with such complications can benefit from a low vision assessment to improve their functionality and their quality of life. In this case study, the importance of early detection and management of ocular complications of JRA, as well as visual rehabilitation through a low vision assessment, are highlighted and discussed. Case Presentation: A 12-year-old female of East Indian descent presented to the Low Vision Center of the University of the West Indies Optometry Eye Unit, bilaterally aphakic (absence of crystalline lens) as a result of complications she developed secondary to a systemic condition diagnosed as JRA. She presented with a distance visual acuity of 2.30 logMAR in the RE, and 1.64 logMAR in the LE, at near she was able to read 8.0 M and 3.2 M at a distance of 8 cm for RE & LE respectively. She has a history of ocular disorder secondary to JRA such as cataract, uveitis, upon low vision assessment a new spectacle prescription and an illuminated stand magnifier of 8D was issued, the patient was satisfied with the outcome of the treatment, management and low vision device issued. Conclusion: At the end of the low vision assessment, the patient was extremely satisfied and looked forward to the prospect of returning to school. Although JRA can have severe ocular complications, with the correct management, a patient’s quality of life can be dramatically improved thus stressing the importance of these types of visual assessments.

文摘Rheumatoid Arthritis(RA)is an autoimmune disorder that hinders the normal functioning of bones and joints and reduces the quality of human life.Every year,millions of people are diagnosed with RA worldwide,particularly among elderly individuals and women.Therefore,there is a global need to develop new biomaterials,medicines and therapeutic methods for treating RA.This will improve the Healthcare Access and Quality Index and also relieve administrative and financial burdens on healthcare service providers at a global scale.Hydrogels are soft and cross-linked polymeric materials that can store a chunk of fluids,drugs and biomolecules for hydration and therapeutic applications.Hydrogels are biocompatible and exhibit excellent mechanical properties,such as providing elastic cushions to articulating joints by mimicking the natural synovial fluid.Hence,hydrogels create a natural biological environment within the synovial cavity to reduce autoimmune reactions and friction.Hydrogels also lubricate the articulating joint surfaces to prevent degradation of synovial surfaces of bones and cartilage,thus exhibiting high potential for treating RA.This work reviews the progress in injectable and implantable hydrogels,synthesis methods,types of drugs,advantages and challenges.Additionally,it discusses the role of hydrogels in targeted drug delivery,mechanistic behaviour and tribological performance for RA treatment.
文摘Amultifunctional liposomal polydopamine nanoparticle(MPM@Lipo)was designed in this study,to combine chemotherapy,photothermal therapy(PTT)and oxygen enrichment to clear hyperproliferating inflammatory cells and improve the hypoxic microenvironment for rheumatoid arthritis(RA)treatment.MPM@Lipo significantly scavenged intracellular reactive oxygen species and relieved joint hypoxia,thus contributing to the repolarization of M1 macrophages into M2 phenotype.Furthermore,MPM@Lipo could accumulate at inflammatory joints,inhibit the production of inflammatory factors,and protect cartilage in vivo,effectively alleviating RA progression in a rat adjuvant-induced arthritis model.Moreover,upon laser irradiation,MPM@Lipo can elevate the temperature to not only significantly obliterate excessively proliferating inflammatory cells but also accelerate the production of methotrexate and oxygen,resulting in excellent RA treatment effects.Overall,the use of synergistic chemotherapy/PTT/oxygen enrichment therapy to treat RA is a powerful potential strategy.

文摘Rheumatoid arthritis(RA),a globally increasing autoimmune disorder,is associated with increased disability rates due to the disruption of iron metabolism.Tripterygium glycoside tablets(TGTs),a Tripterygium wilfordii Hook.f.(TwHF)-based therapy,exhibit satisfactory clinical efficacy for RA treatment.However,drug-induced liver injury(DILI)remains a critical issue that hinders the clinical application of TGTs,and the molecular mechanisms underlying the efficacy and toxicity of TGTs in RA have not been fully elucidated.To address this problem,we integrated clinical multi-omics data associated with the anti-RA efficacy and DILI of TGTs with the chemical and target profiling of TGTs to perform a systematic network analysis.Subsequently,we identified effective and toxic targets following experimental validation in a collagen-induced arthritis(CIA)mouse model.Significantly different transcriptome–protein–metabolite profiles distinguishing patients with favorable TGTs responses from those with poor outcomes were identified.Intriguingly,the clinical efficacy and DILI of TGTs against RA were associated with metabolic homeostasis between iron and bone and between iron and lipids,respectively.Particularly,the signal transducer and activator of transcription 3(STAT3)–hepcidin(HAMP)/lipocalin 2(LCN2)–tartrate-resis tant acid phosphatase type 5(ACP5)and STAT3–HAMP–acyl-CoA synthetase long-chain family member 4(ACSL4)–lysophosphatidylcholine acyltransferase 3(LPCAT3)axes were identified as key drivers of the efficacy and toxicity of TGTs.TGTs play dual roles in ameliorating CIA-induced pathology and in inducing hepatic dysfunction,disruption of lipid metabolism,and hepatic lipid peroxidation.Notably,TGTs effectively reversed“iron–bone”disruptions in the inflamed joint tissues of CIA mice by inhibiting the STAT3–HAMP/LCN2–ACP5 axis,subsequently leading to“iron–lipid”disturbances in the liver tissues via modulation of the STAT3–HAMP–ACSL4–LPCAT3 axis.Additional bidirectional validation experiments were conducted using MH7A and AML12 cells to confirm the bidirectional regulatory effects of TGTs on key targets.Collectively,our data highlight the association between iron-mediated metabolic homeostasis and the clinical efficacy and toxicity of TGT in RA therapy,offering guidance for the rational clinical use of TwHF-based therapy with dual therapeutic and toxic potential.

文摘Rheumatoid arthritis(RA)is a prevalent autoimmune disease whose main features include chronic synovial inflammation,bone destruction,and joint degeneration.Neutrophils are often considered to be the first responders to inflammation and are a key presence in the inflammatory milieu of RA.Neutrophil extracellular traps(NETs),a meshwork of DNA-histone complexes and proteins released by activated neutrophils,are widely involved in the pathophysiology of autoimmune diseases,especially RA,in addition to playing a key role in the neutrophil innate immune response.NETs have been found to be an important source of citrullinated autoantigen antibodies and inflammatory factor release,which can activate RA synovial fibroblasts(FLS)and cause joint damage.This article reviews the role of NETs in the pathophysiology of RA,demonstrating the application of multiple molecules with various therapies,with a view to informing the discovery and development of novel biomarkers and therapeutic targets for RA.
文摘A recent study published in World J Clin Cases addressed the optimal non-steroidal anti-inflammatory drugs(NSAIDs)for juvenile idiopathic arthritis(JIA).Herein,we outline the progress in drug therapy of JIA.NSAIDs have traditionally been the primary treatment for all forms of JIA.NSAIDs are symptom-relief medications,and well tolerated by patients.Additionally,the availability of selective NSAIDs further lower the gastrointestinal adverse reactions compared with traditional NSAIDs.Glucocorticoid is another kind of symptom-relief medications with potent anti-inflammatory effect.However,the frequent adverse events limit the clinical use.Both NSAIDs and glucocorticoid fail to ease or pre-vent joint damage,and the breakthrough comes along with the disease-mo-difying antirheumatic drugs(DMARDs).DMARDs can prevent disease pro-gression and reduce joint destruction.Particularly,the emergence of biologic DMARDs(bDMARDs)has truly revolutionized the therapeutics of JIA,compared with conventional synthetic DMARDs.As a newly developed class of drugs,the places of most bDMARDs in the management of JIA remain to be well estab-lished.Nevertheless,the continuous evolution of bDMARDs raises hopes of improving long-term disease outcomes for JIA.

文摘[Objectives]To investigate the anti-inflammatory effect of Embelia parviflora Wall.polysaccharide on rheumatoid arthritis(RA)in rats.[Methods]RA rat model was induced by type II collagen.After successful modeling,the rats were divided into model group,positive group,low,medium and high dose of E.parviflora Wall.polysaccharide groups,and normal control group.Body mass,toe volume and arthritis index were measured,and thymus index and spleen index were calculated.The levels of interleukin-1β,interleukin-6 and tumor necrosis factor-αin serum and synovial tissue of ankle joint were detected by ELISA.[Results]Compared with the normal control group,the pathological changes such as synovial hyperplasia and unclear layer were observed in the model group,the body mass was decreased(P<0.05),the toe volume,arthritis index,thymus and spleen index were increased(P<0.05),and the levels of IL-1β,IL-6 and TNF-αin serum and ankle synovial tissue were increased(P<0.05).Compared with the model group,the histopathological changes in synovium of ankle joint in the positive group and the medium and high dose groups of E.parviflora Wall.polysaccharide were significantly improved,and the body mass was increased(P<0.05).The toe volume,arthritis index,thymus index and spleen index were decreased(P<0.05).The levels of IL-Iβ,IL-6 and TNF-αin serum and synovial tissue of ankle joint were increased(P<0.05),while there was no significant difference between the low dose group of E.parviflora Wall.polysaccharide and the model group(P>0.05).[Conclusions]E.parviflora Wall.polysaccharide can reduce the body's inflammatory response and improve RA,which may be related to the inhibition of the activation of inflammatory cytokines IL-1β,IL-6 and TNF-α.
文摘Background: Juvenile Idiopathic Arthritis (JIA) is the most prevalent rheumatic disease in children. It is associated with abnormal levels of serum zinc (Zn) and copper (Cu) as during inflammation serum copper concentration increases and zinc decreases. Objective: To assess the serum Zn and Cu levels in different sub-types of JIA patients and their correlation with the disease duration. Methods: This cross-sectional study was conducted over twelve months at the Pediatric Rheumatology Division, Department of Paediatrics, Bangabandhu Sheikh Mujib Medical University. Sixty-nine JIA cases that fulfilled the International League of Association for Rheumatology (ILAR) criteria were taken as cases and age and sex-matched healthy children were considered as controls. The serum Zn and Cu tests were done using the spectrophotometric method with INDIKO PLUS Drug Analyzer. Data were recorded in a pre-designed questionnaire. Data were checked, verified and analyzed manually where continuous variables were analyzed using unpaired t-test and categorical variables using the ANOVA test. Pearson’s correlation coefficient test was used to see the correlation of serum zinc and copper levels with disease duration. Results: Boys were predominant in both case and control groups, with the majority within the 10 to 16-year-age group. Enthesitis-related arthritis (ERA) was the most common subtype followed by sJIA, Oligo JIA, Poly JIA (RF-) and unclassified subtypes. Disease duration was found less than 12 months in 30.4% of JIA patients. Serum analysis revealed a statistically significant reduction in mean zinc levels and increased copper levels in JIA patients compared to controls. This study observed a negative correlation between serum zinc levels and disease duration, whereas serum copper levels exhibited a positive correlation with disease duration. Conclusion: In conclusion, this study revealed that JIA patients exhibit alterations in serum zinc and copper levels. Serum copper levels showed a positive correlation and serum zinc levels showed a negative correlation with the duration of the disease.
文摘Introduction: Rheumatoid arthritis (RA) is a chronic, erosive and deforming inflammatory rheumatic disease. In the era of biotherapies and the arrival of biosimilars in sub-Saharan Africa, the objective of this study was to describe plasma IL-6 variations in RA patients at Cité Verte District Hospital (Cameroon). Material and Methods: Descriptive and analytical cross-sectional study from December 1, 2021 to May 31, 2022. We included patients over 18 years old suffering from RA (ACR/EULAR 2010). Patients with an infection were not included. The data collected were age, sex, smoking status, family history, disease duration, disease activity by DAS28, CRP, rheumatoid factor, and plasma level of IL-6. Bone erosion was sought on radiography and ultrasound. Result: We included 31 patients, 25 of whom were women (80.6%). The mean age was 47.27 ± 17.97 years. Disease activity was predominantly moderate (32.3%) and severe (32.3%). Mean IL-6 level was 15.29 ± 2.36 pg/ml (extremes: 11.26 pg/ml and 20.15 pg/ml). IL-6 levels were higher in patients with a history of smoking. Similarly, IL-6 levels were higher in patients with mildly active RA in remission than in moderately and severely active RA. Mean IL-6 levels were significantly higher in patients with erosive RA (16.3 pg/ml VS 14.6 pg/ml). Conclusion: IL-6 levels were significantly elevated in men, weaned smokers and patients with bone erosions.
文摘Objective:Rheumatoid arthritis(RA)requires comprehensive management.Structured nursing protocols may enhance outcomes,but evidence is limited.This study evaluated the effect of a structured nursing protocol on RA outcomes.Materials and Methods:In this one-group pre-post study,30 Egyptian RA patients completed assessments before and after a 12-week nursing protocol comprising education,psychosocial support,and self-management promotion.Assessments included clinical evaluation of joint counts,erythrocyte sedimentation rate(ESR),and C-reactive protein(CRP)and patient-reported Arthritis Self-Efficacy Scale(ASES),Health Assessment Questionnaire(HAQ),Visual Analog Scale(VAS)for pain,and Hospital Anxiety and Depression Scale(HADS).Results:The study demonstrated significant improvements in both clinical-and patient-reported outcomes.Joint count decreased from 18.4±4.2 to 14.2±3.8(P<0.001),ESR from 30.1±6.8 mm/h to 25.5±6.8 mm/h(P<0.01),and CRP levels from 15.2±3.6 mg/L to 11.8±2.9 mg/L(P<0.01)postintervention.Patient-reported outcomes showed a marked increase in ASES score from 140±25 to 170±30(P<0.001)and reductions in HAQ from 1.6±0.4 to 1.3±0.3(P<0.01),VAS pain score from 7.8±1.7 to 6.2±1.2(P<0.001),and HADS anxiety and depression scores from 11±3 to 8±2(P<0.05)and 10±2 to 7±1(P<0.05),respectively.Conclusion:A structured nursing protocol significantly improved clinical disease activity,physical functioning,pain,self-efficacy,and emotional well-being in RA patients.A multifaceted nursing intervention appears beneficial for optimizing RA outcomes.

文摘BACKGROUND Previous studies in the pre-biological era showed an association of wrist inflammation in juvenile idiopathic arthritis(JIA)with progressive disease course,polyarticular involvement and failure of methotrexate treatment.AIM To describe features of JIA,associated with wrist arthritis.METHODS Data from about 753 JIA patients were included in this retrospective cohort study.The clinical and laboratory features of patients with and without wrist involvement were analyzed.RESULTS Wrist involvement was found in oligoarthritis(5.8%),RF(−)/RF(+)polyarthritis(44.9%/15.0%),enthesitis-related arthritis(17.7%),and systemic(58.6%)JIA categories.Unilateral wrist involvement was typical for oligoarthritis patients,bilateral involvement was either equal to that of unilateral involvement or was more frequent in other categories.Wrist arthritis was found to be associated with female sex,a low incidence of uveitis,and more indications of systemic inflammation,including elevated levels of C-reactive protein,erythrocyte sedimentation rate,and platelets,as well as involvement of the cervical spine,temporomandibular,shoulder,elbow,metacarpophalangeal,proximal interphalangeal,distal interphalangeal,hip,ankle,and tarsus arthritis.The number of patients with hip osteoarthritis and hip replacement was also higher.Wrist arthritis was associated with a lower probability of achieving remission[hazard ratio(HR)=1.3(95%CI:1.0-1.7),P=0.055],and a higher probability of being treated with biologics[HR=1.7(95%CI:1.3-2.10,P=0.00009)].CONCLUSION Wrist arthritis in JIA patients is a marker of a severe disease course,characterized by more intensive inflammation,unfavorable outcomes,and.requiring more intensive treatment with early administration of biologics.Close monitoring of wrist inflammation with ultrasound and MR assessment with early biological treatment might improve the outcomes.

文摘BACKGROUND Lung damage in systemic juvenile arthritis(sJIA)is one of the contemporary topics in pediatric rheumatology.Several previous studies showed the severe course and fatal outcomes in some patients.The information about interstitial lung disease(ILD)in the sJIA is scarce and limited to a total of 100 cases.AIM To describe the features of sJIA patients with ILD in detail.METHODS In the present retrospective cohort study,information about 5 patients less than 18-years-old with sJIA and ILD were included.The diagnosis of sJIA was made according to the current 2004 and new provisional International League of Associations for Rheumatology criteria 2019.ILD was diagnosed with chest computed tomography with the exclusion of other possible reasons for concurrent lung involvement.Macrophage activation syndrome(MAS)was diagnosed with HLH-2004 and 2016 EULAR/ACR/PRINTO Classification Criteria and hScores were calculated during the lung involvement.RESULTS The onset age of sJIA ranged from 1 year to 10 years.The time interval before ILD ranged from 1 mo to 3 years.The disease course was characterized by the prevalence of the systemic features above articular involvement,intensive rash(100%),persistent and very active MAS(hScore range:194-220)with transaminitis(100%),and respiratory symptoms(100%).Only 3 patients(60%)developed a clubbing phenomenon.All patients(100%)had pleural effusion and 4 patients(80%)had pericardial effusion at the disease onset.Two patients(40%)developed pulmonary arterial hypertension.Infusion-related reactions to tocilizumab were observed in 3(60%)of the patients.One patient with trisomy 21 had a fatal disease course.Half of the remaining patients had sJIA remission and 2 patients had improvement.Lung disease improved in 3 patients(75%),but 1 of them had initial deterioration of lung involvement.One patient who has not achieved the sJIA remission had the progressed course of ILD.No cases of hyper-eosinophilia were noted.Four patients(80%)received canakinumab and one(20%)tocilizumab at the last follow-up visit.CONCLUSION ILD is a severe life-threatening complication of sJIA that may affect children of different ages with different time intervals since the disease onset.Extensive rash,serositis(especially pleuritis),full-blown MAS with transaminitis,lymphopenia,trisomy 21,eosinophilia,and biologic infusion reaction are the main predictors of ILD.The following studies are needed to find the predictors,pathogenesis,and treatment options,for preventing and treating the ILD in sJIA patients.
文摘Objective:To explore the correlation between the change of D-dimer level and rheumatoid arthritis complicated with interstitial lung disease.Methods:From January 2022 to February 2024,20 rheumatoid arthritis patients complicated with interstitial lung disease(interstitial lung disease group),20 rheumatoid arthritis patients without interstitial lung disease(without interstitial lung disease group),and 20 healthy people(control group)in Xijing Hospital were selected for this study.The fasting venous blood of the three groups of subjects was collected and their D-dimer,C-reactive protein(CRP),rheumatoid factor(RF),and erythrocyte sedimentation rate(ESR)were detected.Subsequently,the correlation between each index and rheumatoid arthritis complicated with interstitial lung disease was analyzed.Results:The D-dimer level of the interstitial lung disease group was significantly higher than the other two groups(P<0.05).The D-dimer level of the group without interstitial lung disease was significantly higher than the control group(P<0.05).CRP levels in the interstitial lung disease group and the group without interstitial lung disease were significantly higher than those of the control group(P<0.05).The ESR and RF levels of the interstitial lung disease group were significantly higher than the other two groups(P<0.05).The levels of ESR and RF levels of the group without interstitial lung disease were significantly higher than the control group(P<0.05).Conclusion:D-dimer levels of rheumatoid arthritis patients are higher than those of healthy individuals,and those complicated with interstitial lung disease present even higher levels.This finding shows that there is a correlation between D-dimer levels and rheumatoid arthritis with interstitial lung disease,which may facilitate the evaluation and diagnosis of this disease.
文摘Objective:To study the effect of Helicobacter pylori infection on rheumatoid arthritis and T-lymphocyte subpopulations in patients with rheumatoid arthritis and to provide a new method for the treatment of rheumatoid arthritis by removing Helicobacter pylori from patients.Methods:60 patients with rheumatoid arthritis admitted to the hospital from May 2022 to May 2023 were selected for the study,and all patients underwent a 13-carbon urea breath test to detect gastric H.pylori and the test results showed that 20 cases were negative and 40 cases were positive.The 40 positive patients were divided into the treatment group(n=20)and non-treatment group(n=20)by random number table method and the treatment group was given anti-Helicobacter pylori treatment,and the non-treatment group was given maintenance rheumatoid basic treatment,comparing the anti-cyclic citrulline peptide(CCP),DS28 score,peripheral blood T-lymphocyte subsets(CD4^(+)T-lymphocytes,CD8^(+)T-lymphocytes,CD4^(+)/CD8^(+)ratio)before and after the treatment of patients by 13-carbon urea respiration test(pylori-negative group,20 patients)and those who were positive for the treatment of H pylori(pylori-positive group,40 patients).Besides,the correlation of peripheral blood T-lymphocyte subsets and disease activity between treatment and non-treatment groups in the pylori-positive group was identified together with the correlation of DS28 scores,TNF-αlevels,sedimentation and immunoglobulin,lymphocyte subsets in the pylori-positive treatment group and positive non-treatment group as well as the level of globulin,lymphocyte subsets,and peripheral blood lymphocytes before and after treatment.Results:Before treatment,CCP,DS28 score,CD8^(+)T lymphocyte level of the pylori-negative group were lower than that of the positive group,and CD4^(+)T lymphocyte and CD4^(+)/CD8^(+)ratio were higher than that of the positive group(P<0.05);after treatment,the indexes of the pylori-positive group improved,and there was no significant difference in the comparison of the indexes with those of the pylori-negative group(P>0.05);the positive treatment group had a DS28(3.19±1.02)points,positive non-treatment group DS28(5.36±1.85)points,non-treatment group DS28 score and CD4^(+)T lymphocytes,CD4^(+)/CD8^(+)negative correlation with CD8^(+)T lymphocytes showed a positive correlation(P<0.05);before the treatment,pylori-positive treatment group and non-treatment group DS28 scores,TNF-αlevels,peripheral blood T lymphocyte subpopulation levels were not significantly different(P>0.05);after treatment,DS28 score,TNF-αlevel,CD8^(+)T of the treatment group were lower than those of the non-treatment group,and CD4^(+)T lymphocytes and CD4^(+)/CD8^(+)ratio were higher than those of the non-treatment group(P<0.05).Conclusion:H.pylori affects the level of T lymphocyte subsets in patients with rheumatoid arthritis,and there is a certain correlation between the two.Removal of H.pylori can improve the level of T lymphocyte subsets,which is important for the treatment of patients with rheumatoid arthritis.

文摘Rheumatoid arthritis(RA)is a systemic autoimmune disease characterized by synovitis.This disease tends to recur,persist,and is difficult to cure.The pathogenesis of RA is complex.Currently,the commonly used treatments for RA—non-steroidal anti-inflammatory drugs(NSAIDs),disease-modifying anti-rheumatic drugs(DMARDs),glucocorticoids,and immunosuppressants—have notable side effects with long-term use and may be ineffective for some patients.Therefore,it is crucial to find drugs with limited side effects and significant curative effects.Xinjiang's local characteristic drugs have a long history,abundant resources,and are known for their safety and effectiveness in treating RA.In recent years,many studies have reported on the mechanisms of action and therapeutic effects of Xinjiang's local characteristic drugs on RA.This article reviews the pathogenesis of RA,as well as the research progress and treatment characteristics of Xinjiang-featured drugs.
