RESUMO

This study evaluated the possible association between SNPs in cytokines coding genes, namely IL10, IL6 and IFNG, cytokines serum levels and clinical assessment' scores in patients with Rheumatoid Arthritis(RA). SNPs genotyping was performed in 126 RA patients and 177 healthy individuals with Taqman probes specific for IL10 -1082 (T>C, rs1800896);INFG -1616 (A>G, rs2069705) and IL6 -174 (G>C, rs1800795) variants,positioned in regulatory regions. Cytokine Bead Array (CBA) was used to measure cytokine levels. We found association between INFG -1616 G allele(p = 0.0210; OR = 1.605) and INFG -1616 GG genotype (p = 0.0268; OR =2.609) and RA susceptibility. We also observed association between IL10 -1082 TT genotype and high clinical disease activity index (CDAI) values (p = 0.026; OR = 1.906; 95% CI = 1.082 - 3.359), IL10 -1082 CC genotype and low CDAI values (p = 0.016; OR = 0.256) and INFG -1616 AA and high CDAI values (p = 0.025; OR = 2.919). IL10 -1082 CC also exhibited the lowest IL-10 levels than IL10 -1082 TT (p = 0.020) and IL10 -1082 TC (p = 0.032). Finally, we verified higher IL-6 value in the RA patients than healthy control group (p = 0.007) and an association between high IL-6 levels and increased CDAI (r = 0.4648, p = 0.0015); DAS 28 (r = 0.3933, p= 0.0091), presence of bone erosions (r = 0.3170, p = 0.0361), ESR levels(r = 0.3041, p = 0.0448) and IFN-γ levels (r = 0.3049, p = 0.0468).Altogether, we suggest that IL10 -1082 (T>C, rs1800896) and INFG -1616(A>G, rs2069705) polymorphisms as well as IL-6 levels alterations may play a role for prognostic and disease follow-up.

RESUMO

BACKGROUND: Caulophyllum robustum Maxim (CRM) is a medicinal compound of the Northeast and is commonly used in China for the treatment of rheumatic pain and rheumatoid arthritis (RA). A preliminary study found that CRM has good anti-inflammatory, analgesic and immunosuppressive effects. However, the specific links and targets for its function remain unclear. Our study aimed to provide a mechanism for the action of Caulophyllum robustum Maxim extraction (CRME) against RA and to establish a method for studying disease treatment using Chinese medicine. METHODS: The 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) method was used to detect the toxicity of CRME in L929 cells, and the concentration ranges of the blank, model, and CRME drug groups were determined. Differentially expressed long non-coding RNAs (lncRNAs) and messenger RNAs (mRNAs) were identified between the three groups. Gene Ontology (GO) and pathway enrichment analyses were performed to analyze the biological functions and pathways of the differentially expressed genes. Expression of Hist1h2bj, Hist1h2ba, Zfp36, Ccl3, Cxcl2 and Egr1 in the blank, model and drug groups was detected by quantitative real-time PCR (qRT-PCR), and the role of CRME on the above factors was determined to ensure consistency with the chip data. RESULTS: A total of 329 significantly upregulated genes and 141 downregulated genes were identified between the blank and model groups. A total of 218 significantly upregulated genes and 191 downregulated genes were identified between the CRME drug group and model group. CRME has a significant role in multiple pathways involved in the occurrence and development of RA. Additionally, Hist1h2bj, Hist1h2ba, Zfp36, Ccl3, Cxcl2, and Egr1 were observed in modules of the lncRNA-mRNA weighted co-expression network, consistent with the chip data. CONCLUSIONS: CRME has regulatory effects on inflammatory factors, the histone family, chemokines and their ligands that are related to RA-related cytokines, the RA pathway, the TNF signaling pathway, the Toll receptor-like signaling pathway, the chemokine signaling pathways and other pathways are related to the course of RA.

RESUMO

Plenty of studies demonstrated an association between a Vitamin D deficiency and several autoimmune disorders, such as diabetes mellitus, systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA) in adult patients. This study was aimed to assess probable association between the 25-hydroxyvitamin D [25(OH)D] level and juvenile idiopathic arthritis (JIA) features and the possible relationship between serum vitamin D level and disease activity. 69 patients with JIA were examined and 15 healthy children were chosen as the control group. The mean age of patients was 10 years 8 months ±4 years 6 months (45 female, 24 male). 25 patients with oligoarthicular subtype of disease, 34 with poliarthicular sybtype and 10 patient with undifferentiated arthritis . The total duration of the disease was 4 years 1 month ± 1 year 1 month. Patients got methotrexate therapy (15mg/m2). Any of the patients were not treated by corticosteroids. The serum level of vitamin D was measured through blood test by chemiluminescence method. The relationship between the level of vitamin D and disease activity was analyzed based on juvenile arthritis disease activity score (JADAS27). The average level of vitamin D in serum was 22,69±7,8 ng/ml at the control group the vitamin D status was 28,67±5,06 ng/ml. In spite of the fact that a decrease in vitamin D status was observed in both groups, however in the group of healthy children it was significantly higher (p>0.05). Using the regression method, a significant relationship was established between the number of active joints and the age of patients, duration of disease, the level of vitamin D in serum, the number of injured joints, and disease activity (accordant to JADAS27 score) (number of active joints = - 1,144 + 0,005 x age of patients - 0,007x duration of disease + 0,292 x the number of injured joints + 0,033 x level of vitamin D + 0,077 x the number of points accordant to JADAS27). The monitoring of vitamin D level is advisable to carry out during observing the children with JIA. It can be useful for timely correction of vitamin D deficiency and preventions both skeleton and non-skeleton complications. That may improve the quality of life of patients and their families.

RESUMO

The wrist is a rare location of septic arthritis. It often involves patients with preexisting joint disease which symptoms could be confused with infection making the diagnosis more difficult and usually delayed. It is often responsible for residual functional impairment and for a high mortality rate among vulnerable patients. We report 6 cases of septic arthritis of the wrist in 3 males and 3 females. The mean age was 32 years in the male patients and 66 in the female patients. All the women were followed for rheumatoid arthritis. Biological results showed elevated rates of white blood cells and c-reactive protein in all the patients. Joint fluid analyses showed elevated white blood cell count. The treatment was medico-surgical consisting in synovectomy, joint debridement and immobilization of the wrist. At the average follow-up of 1 year and 4 months, 3 patients recovered a perfect mobility of the wrist without any limitation of the range of motion nor the strength. Three patients developed stiffness of the wrist.

RESUMO

Purpose: The purpose of this study was to assess the efficacy of mouthwash containing essential oils and curcumin (MEC) as an adjunct to nonsurgical periodontal therapy on the disease activity of rheumatoid arthritis (RA) among RA patients with chronic periodontitis (CP). Materials and Methods: A triple-blinded controlled trial was conducted among 45 female RA patients with CP randomized into three treatment groups as follows: Group A: scaling and root planing (SRP) with 0.2% chlorhexidine mouthwash as an adjunct (n = 15), Group B: SRP with MEC as an adjunct (n = 15), and Group C: SRP alone (n = 15). RA disease activity was assessed using erythrocyte sedimentation rate, serum C-reactive protein, serum anti-citrullinated protein antibody, and serum rheumatoid factor. Periodontal disease activity was assessed using plaque index, clinical attachment level (CAL), and pocket depth (PD). All parameters were recorded at baseline and 6 weeks thereafter. Data were assessed using one-way ANOVA and paired t-test. Results: A significant reduction in periodontal and RA disease activity parameters was observed from baseline to 6 weeks following intervention (P < 0.05). The highest percentage of mean reduction in plaque index and RA parameters from baseline to 6 weeks was observed in Group B followed by Groups A and C. The highest percentage of mean reduction in PD and CAL was observed in Group A followed by Groups B and C (P < 0.001). Conclusion: This study reveals that MEC as an adjunct to SRP is effective in reducing the disease activity of RA and CP, thereby warranting the use of the same.

RESUMO

Objective To explore the role of multidrug resistance gene-1(MDR1)gene in methotrexate(MTX)resistance in patients with rheumatoid arthritis(RA).Methods Fibroblast-like synoviocytes(FLS)from RA patients were infected with recombinant adenovirus Ad-EGFP-MDR1 in vitro to obtain MDR1 over-expressed RA FLS.The transcription level of MDR1 gene and the expression level of its coding product P-glycoprotein(P-gp) rotein were detected by real-time PCR and Western blot analysis.The efflux function was verified by rhodamine 123 efflux assay.The resistance to MTX was detected by MTT assay.Results RA FLS were infected with recombinant adenovirus Ad-EGFP-MDR1;72 hours later,the particles size in MDR1 over-expressed RA FLS increased,the cell volume became larger,and the growth rate decreased.The transcription level of MDR1(1.4325±0.3924 vs.0.0650±0.0070;t=6.035,P=0.004),the expression level of P-gp protein(1.8667±0.2857 vs. 0.9367±0.0551;t=5.536,P=0.005),and the ability of extracellular rhodamine 123(979.43±196.81 vs.1680.06±147.04;t=-4.940,P=0.008) in MDR1 over-expressed RA FLS were significantly higher than those of negative virus control RA-FLS,and the survival rate of MDR1 over-expressed RA FLS was significantly increased at each concentration of MTX(P<0.05).Conclusion The high expression of MDR1 can affect the efflux ability to MTX by up-regulating the expression of P-gp,thus enhancing the drug resistance to MTX in RA FLS.

RESUMO

The aim was to study the level of some cytokines (IL-2, IL-6, IL-8 TNFα) and calcium regulating hormones (calcitonin, parathyroid hormone, 25 (OH) D) in the blood of patients with rheumatoid arthritis (RA) depending on rheumatoid factor (RF) and the assessment of the role of the revealed violations in the pathogenesis of bone loss in this pathology. For this purpose, 74 patients with RA (59 women, 15 men) aged from 27 to 71 were examined. On the basis of RF in the blood serum, the patients were divided into 2 groups: seronegative and seropositive RA. The control group included 16 healthy individuals (13 women, 3 men). The results obtained that the serological variant of RA affects the serum levels of proinflammatory cytokines and calcium-regulating hormones: more pronounced changes were found in seropositive RA. The high production of IL-2, IL-6, IL-8, TNF-α and parathyroid hormone detected in both groups of patients undoubtedly contributes to the mechanisms of bone loss in RA. In both groups we detected hypovitaminosis D. This results recommended to use this vitamin in the complex treatment of RA.

RESUMO

Ophthalmologic manifestation of Sjogren's disease (SD) and rheumatoid arthritis (RA) is dry keratoconjunctivitis (dry eye disease; DED). PURPOSE: To study the relationship of polymorphic markers rs7947461 (C/T), rs915956 (C/T), rs4144331 (C/A) of the TRIM21 gene with the severity of DED in patients with RA and SD. MATERIAL AND METHODS: The study included 70 patients with RA (n=27) and SD (n=43). The control group consisted of volunteers without a history of RA or SD (n=35). Alleles of the polymorphic marker C660T rs7947461 of the TRIM21 gene were identified using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method; alleles of the polymorphic marker rs915956 (C/T) and rs4144331 (C/A) of the TRIM21 gene were identified by analyzing DNA melting curves. RESULTS: An association was found between the predisposing genotype (TT) of rs7947461 polymorphic marker and the risk of developing severe DED. The AA genotype of rs4144331 polymorphic marker was found only in severe DED (c2=7.74; OR=17.46, CI95%=1.96-318.38, p=0.02). CONCLUSION: An association was established between rs7947461 (rs660) and rs4144331 and the risk of developing severe DED.

RESUMO

The article reviews literature on relationships between polymorphic variants of the genes THBS1, GTF2I, MUC1, TRIM21, STAT4, PTPN22 with clinical features of dry keratoconjunctivitis in rheumatoid arthritis and Sjogren's syndrome. The development and implementation of a method for analyzing polymorphic gene variants used to diagnose dry keratoconjunctivitis in rheumatoid arthritis and Sjogren's syndrome will allow assessment of the possibility of developing dry keratoconjunctivitis and/or its progression in patients with autoimmune diseases or in people at risk. Determination of clinical and morphological regularities of dry keratoconjunctivitis in accordance with the revealed molecular and genetic changes will contribute to better understanding of the etiology and pathogenesis of ophthalmological manifestations of autoimmune diseases, and will also help improve the diagnostics and prognosis of dry keratoconjunctivitis.

RESUMO

Osteoarthritis (OA) may be associated with substantial work disability, morbidity, costs, and increased mortality rates, often similar to rheumatoid arthritis (RA), documented in many published reports over the last 4 decades. However, OA generally has been viewed as less severe than RA. This discrepancy may be explained in part by:a) RA may have been considerably more severe in the past, prior to effective therapies.b) most older individuals have radiographic joint damage, which often is not associated with clinical symptoms.c) RA is associated with abnormal laboratory tests, which are regarded as conveying greater significance than symptoms of pain and disability according to a "biomedical model," the dominant paradigm of modern medicine.d) Most reports of OA and RA have emphasised differences between the 2 diseases even beyond laboratory abnormalities in pathogenesis, physical findings, and imaging.e) Even pain and functional disability seen in both diseases are assessed using different patient self-report questionnaires, a WOMAC (Western Ontario McMaster Universities osteoarthritis index) in OA, and HAQ (health assessment questionnaire) in RA.An identical measure is required for optimal direct comparisons, which has been used in 8 studies performed between 1979 and 2019 at 8 sites in North America, Europe, and Australia. These studies were primarily based on retrospective analyses at sites which collected a patient questionnaire in routine clinical care by all patients at all visits to inform clinical decisions. A pain visual analogue scale (VAS) was higher in OA compared to RA in 11/12 patient groups, while physical function on a HAQ (health assessment questionnaire) or derivative MDHAQ (multidimensional HAQ) and RAPID3 (routine assessment of patient index data) were slightly higher in RA before 2013 and higher in OA in later reports. Furthermore, a study of population-based data from the 1978 US Health Interview Survey indicated similar levels of disability and earnings losses according to surrogate variables for OA and RA. Therefore, at least over the last 40 years, pain and functional disability in OA have appeared to be severe and similar to RA. These observations also-illustrate the potential value of using an identical patient questionnaire in all patients at all visits in routine care settings, analogous to using the same laboratory tests such as erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) in all rheumatic diseases, and maintaining a database of the results for later analyses.

RESUMO

Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory autoimmune disease associated with increased prevalence of type 2 diabetes mellitus (T2DM). Here, we investigated the effect of the combination of cyclooxygenase (COX)-2 inhibitors and metformin on the rate of admission in patients with RA and T2DM and compared it with that of only COX-2 inhibitors.In total, 1268 subjects with RA and T2DM under COX-2 inhibitor and metformin therapy were selected from the National Health Insurance Research Database of Taiwan, along with 2536 patients as 1:2 sex-, age-, and index year-matched controls without metformin therapy. Cox proportional hazard analysis was used to compare the rate of admission during the 10 years of follow-up.At the end of the follow-up, 72 enrolled subjects (1.89%) had admission, including 9 from the combination group (0.71%) and 63 from the COX-2 inhibitor group (2.48%). The combination group was associated with a lower rate of admission at the end of follow-up (P < .001). Cox proportional hazard regression analysis revealed the lower rate of admission for subjects under combination therapy (adjusted hazard ratio of 0.275; 95% confidence interval = 0.136-0.557, P < .001).Patients with RA and T2DM receiving the combination of COX-2 inhibitors and metformin were associated with lower admission rate than those on COX-2 inhibitors alone, and this effect may be attributed to the decrease in the levels of proinflammatory factors.

RESUMO

Risk of development of malignant tumors increases in elderly people. There are numerous clinical symptoms mimicking primary rheumatic diseases in the course of cancers, referred to as paraneoplastic rheumatologic syndromes. They are not caused directly by the tumor or its metastases, but result from the action of biologically active substances released by cancer cells and abnormal immunological reactions. Paraneoplastic rheumatologic syndromes may precede the diagnosis of cancer, occur simultaneously or occur after the diagnosis of malignancy. In clinical practice, it is very difficult to distinguish paraneoplastic syndromes from idiopathic rheumatic diseases. However, some clinical features may suggest the paraneoplastic nature of rheumatic diseases, including the onset of symptoms in old age, atypical and rapidly progressive course or poor response to conventional treatment. Early and well-targeted diagnostics allow the diagnosis of often latent neoplasm, and its effective treatment may lead to resolution of paraneoplastic rheumatic symptoms. This paper discusses selected paraneoplastic rheumatologic syndromes that often occur in older people, including carcinomatous polyarthritis, remitting seronegative symmetrical synovitis with pitting edema (RS3PE), palmar fasciitis-polyarthritis syndrome, hypertrophic osteoarthropathy, tumor-induced osteomalacia, cancerassociated myositis, paraneoplastic scleroderma like syndrome, paraneoplastic vasculitis and paraneoplastic Raynaud's syndrome.

RESUMO

Rheumatoid arthritis (RA) is a chronic, systemic connective tissue disease, characterized by progressive, destructive polyarthritis with internal organs involvement due to active, systemic inflammation. The onset of disease occurs usually in 4th or 5th decade of life. Since the general population is ageing, beginning of RA in older age is more and more common. The term elderly onset of rheumatoid arthritis (EORA) describes the disease with onset at age over 60. Several observational studies indicated, that proportion of women and men is comparable in EORA. Clinical course of the disease is characterized by sudden onset with general constitutional symptoms, high disease activity and inflammatory parameters. Involvement of large joints is more common, specially shoulder joints. Antibodies typical for RA (rheumatoid factor, anti-citrullinated peptide) are usually negative. More advanced destructive changes of joints and functional impairment are also characteristic for EORA patients in comparison with younger onset of RA (YORA). In clinical practice the use of methotrexate and biological drugs is less common, and glucocorticosteroids more common in EORA. Due to high RA activity, patients with EORA should be treated in the same way as YORA, with careful monitoring due to higher risk of adverse events associated with treatment.

RESUMO

Dysregulated proinflammatory cytokine expression may result in the development of severe pathologies, such as rheumatoid arthritis, psoriasis, and neurodegenerative diseases. Transgenic mice and, in particular, those with controllable systemic overexpression of proinflammatory cytokines have recently become an essential instrument to study the molecular mechanisms underlying disease development. Importantly, many of the models are humanized by introducing a human cytokine gene, while leaving or removing the respective endogenous mouse gene. Humanized mice are especially valuable for biomedical research as they provide a relevant model to develop therapies based on blocking the pathogenic activity of a cytokine or to establish the functional significance of genome polymorphisms. The review discusses the available humanized mouse models with overexpression of key proinflammatory cytokines (TNF, IL-ip, and IL-6) and inflammatory cytokines with more specific functions (IL-8, IL-17, and IL-32) and their significance for basic and clinical research.

RESUMO

The present study evaluated the association between appendectomy and rheumatoid arthritis (RA) using a national sample cohort of the Korean population. In this cohort study, the Korean National Health Insurance Service-National Sample Cohort of individuals ≥20 years old was collected from 2002 to 2013. A total of 14,995 appendectomy participants were 1:4 matched with 59,980 control subjects for age, group, sex, income group, region of residence, hypertension, diabetes, and dyslipidemia. We analyzed the occurrence of RA in both the appendectomy and control groups. Appendectomies were identified using operation codes for appendicitis only. RA was defined by International Classification of Disease-10 codes (M05 or M06) and medication histories. Crude and adjusted hazard ratios (HRs) were analyzed using a stratified Cox proportional hazard model. Subgroup analyses were performed on groups stratified by age and sex. The adjusted HR for RA was 1.02 (95% confidence interval = 0.76-1.38) in the appendectomy group (P = .883). In all of the subgroup analyses according to age and sex, the adjusted HRs for RA were not higher in the appendectomy group than those in the control group. We could not identify any significant relationship between appendectomy and RA.

RESUMO

To evaluate the effect of Tripterygium Glycosides Tablets extract in the treatment of rheumatoid arthritis( RA). Clinical trials of treating rheumatoid arthritis with Tripterygium Glycosides Tablets published by Meta-analysis were retrieved from EMbase,PubMed,Clinical Trials,Web of Science,Cochrane Library,CNKI,Wanfang,VIP,CBM and Chi CTR,and comprehensively analyzed. A total of 3 studies were enrolled,the modified Sharp score( m TSS),tender join joint erosions( JE) and joint space narrowing( JSN) of Tripterygium Glycosides Tablets group were significant superior to those of control group,including positive drugs methotrexate( MTX) and salazopyridine( SSZ)( P<0. 01). Tripterygium Glycosides Tablets had an effect in treating RA. Due to the small sample size,this study shall be verified with high-quality,large-sample-size double-blinded RCTs.

RESUMO

Traditional Chinese medicine Tripterygium wilfordii Hook.f( TWHF) is a natural botanical drug in China. It has complex chemical compositions and has been used for a long history. TWHF was used as an insecticide to protect crops at early stage,and it was later found to have significant effects in the treatment of rheumatoid arthritis,attaining great concerns. With further researches,it was found that TWHF can treat various diseases in the medical field due to a variety of pharmacological activities such as anti-cancer,neuroprotection,anti-inflammatory and immune-suppressing,particularly. Multiple extracts of TWHF have unique immunosuppressive function,playing an immune role through multi-target and multi-channel,with significant effect in the treatment of autoimmune diseases. As an immune-suppressing drug,TWHF is worthy of in-depth research due to its broad application prospects. While achieving good clinical efficacy,reports about its toxic effects to multiple systems of the body are also increasing,greatly hindering its clinical application. In order to fully understand the immune-suppressing function of TWHF and reduce or avoid the occurrence of toxic and side effects,we summarized recent progress of TWHF on the immune organs,cells and factors in recent years,as well as the pharmacology and toxic effects,hoping to provide a scientific and reasonable reference for its wider use in clinical treatment.

RESUMO

Rheumatoid arthritis( RA) is an autoimmune disease characterized by chronic and aggressive polyarthritis. The innate immunity mechanism plays a key role in the pathogenesis of RA. Tripterygium wilfordii and its extracts have regulatory effects on innate immune cells including macrophages,dendritic cells,neutrophils,mast cells,NK cells,NKT cells,etc.,as well as a variety of innate immune molecules including cytokines,adhesion molecules,patterns recognition receptor( PRR) and the complement molecules,showing a regulatory effect in the pathogenesis of RA innate immunity. In this paper,the recent domestic and foreign researches on the pathogenesis of RA with innate immunity involved were reviewed and the research status of T. wilfordii and its extracts on the regulation of innate immunity involved in RA was summarized.
