    INTRODUCTION: Rheumatoid arthritis (RA) is an autoimmune systemic inflammatory disorder characterised by symmetrical polyarthritis which leads to damage of joints if untreated. Early diagnosis and treatment of RA to achieve tight control of the disease will improve outcome and prevent disability.

    OBJECTIVE: We aimed to examine the delays in the diagnosis of RA in patients presenting to the Rheumatology Unit, Sarawak General Hospital (SGH).

    METHODS: Data on demographics and various delays were collected from the medical records from January 2015 until March 2018. Patient delay is defined as from the time onset of symptom to the first primary care presentation. Primary care delay is defined as from the first primary care presentation to referral to rheumatology. Rheumatology delay is defined as from rheumatology referral to appointment at the rheumatology clinic. Disease modifying anti-rheumatic drugs (DMARDS) delay is defined as from the rheumatology clinic appointment to starting DMARDS. Total delay is from symptom onset to starting DMARDS.

    RESULTS: There were 84 new patients diagnosed with rheumatoid arthritis, out of which 66 were females (78.6%). The mean age was 54.1±12.0 years. Only 19 patients (22.6%) were treated with DMARDS within 12 weeks of symptom onset. The median time for patient delay was four weeks (Interquartile range (IQR) 2-20 weeks), while the median time primary care delay was 11 weeks (IQR 4-24 weeks). The median time for rheumatology delay was zero weeks (IQR 0- 1 week) and the DMARDS delay was zero week (IQR 0). The median time from symptom onset to DMARDS initiation was 23.5 weeks (IQR 13.25-51 weeks).

    CONCLUSION: The delays in the diagnosis of rheumatoid arthritis were mainly from the patient and primary care.

    Rheumatoid arthritis (RA) is a major health burden in Asia Pacific affecting the quality of life of patients and consuming healthcare resources. According to recent estimates from the World Health Organization-International League Against Rheumatism-Community Oriented Program for Control of Rheumatic Diseases, prevalence is around 0.3%-0.5%. Management guidelines have helped to improve treatment across this diverse region. To gain better insight into current real-world management applications in view of these guidelines, virtual meetings were conducted in mid-2020 to explore perspectives of rheumatologists and patients, as well as discuss the impact of coronavirus disease 2019 on RA management. Patients and rheumatologists from Hong Kong, Malaysia, Singapore, the Philippines, Thailand, India, Pakistan, and Taiwan were included, representing a diverse mix of healthcare systems, wealth, ethnicity and culture. Despite many countries having prospered in recent years, similar challenges in RA diagnosis and treatment were identified. The daily impact and patient experience of RA were also similar across countries, marked by "silent" pain and disability, and universal misunderstanding of the disease. Late diagnosis and treatment, and barriers to access to appropriate treatment, remain problematic. The experience shared by Taiwan offers a glimmer of hope, however, wherein patient advocacy groups have succeeded in being included in policy-making decisions and securing access to advanced treatment. Real-world solutions that pay heed to the unique local needs and diversity of Asia Pacific are required to improve RA management, which will take time. In the interim, help can be sought from the trained, non-rheumatologist community to reduce some of the disease burden.

    The search for novel biomarkers has taken centre stage in the past decades of research in Rheumatoid Arthritis (RA). The purpose of the present study was to determine the correlation of serum matrix metalloproteinase-3 (MMP-3) with disease activity, joint damage and functional disability in patients with RA. We consecutively recruited RA patients who were under follow-up at the Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Information on the RA disease characteristics were obtained from the medical records and all RA patients were
    assessed for DAS28 (disease activity score based on 28 joints) and Stanford Health Assessment Questionnaire (HAQ) 8-item Disability Index (HAQ-DI). The hand radiographs of the RA patients were assessed for joint damage using the Modified Sharp Score (MSS). Serum MMP-3 levels from RA patients and healthy controls were measured using the ELISA method. We recruited a total of 77 RA patients and 18 healthy controls. The serum MMP-3 levels were significantly higher among the RA patients (p<0.05). There were significant correlations between the serum MMP3 levels and MSS (r =0.327) and HAQ-DI (r=0.256), both p<0.05. The mean serum MMP levels in RA patients with radiographic joint erosions was significantly higher than in patients without erosions (p<0.05). Likewise, the subjects with significant functional impairment i.e HAQ-DI ≥1; had significantly higher mean MMP-3 levels compared to RA patients without significant disability (p<0.05). Using multivariate analysis, HAQ-DI remained the independent predictor of serum MMP-3 in RA patients. Serum MMP-3 is a potential biomarker and predictor of radiographic joint damage and functional disability in RA.

    Tumor necrosis factor alpha (TNFα) is a multifunctional cytokine which plays a pivotal role in the pathogenesis of rheumatoid arthritis (RA). Apart from its well recognized proinflammatory properties, it is known to interfere with lipid metabolism and erythropoiesis. We evaluated the effects of adalimumab on hematologic, lipid and inflammatory parameters using data from patients on adalimumab 40 mg fortnightly from 2 centers in Malaysia. Mean changes in laboratory values from baseline to Weeks 4, 12 and 24 were compared using paired T test and Wilcoxon signed-rank test. We studied 18 patients with RA who were on adalimumab 40 mg fortnightly. The inflammatory markers i.e. erythrocyte sedimentation rate and C reactive protein showed significant changes as early as at week 4 compared to baseline with p values of 0.003 and 0.005, respectively. From a baseline of high disease activity with a mean Disease Activity Score using 28 joint counts (DAS 28) of 5.3, there was a steady improvement in the disease activity and remission was achieved at week 24 with a DAS 28 of 2.4. The hemoglobin level improved at week 12 (p=0.013) and this was sustained till week 24. As opposed to previous studies, the LDL level significantly decreased at week 12 (p=0.015) and this change persisted till week 24 (p=0.001). The total cholesterol showed a similar pattern as the LDL. The pharmacodynamics of adalimumab therapy in rheumatoid arthritis extend beyond the joints with favorable effects on haemoglobin and lipid profile.

    The main objective was to determine the predictors of diastolic dysfunction in rheumatoid arthritis (RA). Articles pertaining to diastolic dysfunction in RA were retrieved from Scopus, EBSCO, PubMed, Web of Science, and Cochrane Library databases. Keywords such as: diastolic, cardiac, left ventricular function, heart failure, rheumatoid arthritis, and cardiac failure were used. Studies, which examined factors, or predictors of diastolic dysfunction in RA, and those with echocardiographic evaluation of diastolic dysfunction, were included. A total of 8 studies met the eligibility criteria. Most studies (6 out of 7 studies) demonstrated a significant inverse relationship between the E (early)/A (late) ratio and disease duration. The pooled analysis using the random effects model revealed a significant but weak inverse relationship between the ratio of the E to A ventricular filling velocities (E/A) ratio and the disease duration (p less than 0.05, r=-0.385). There was a significant relationship between E/A ratio and disease duration in RA.

    OBJECTIVE: This study aimed to estimate annual direct cost attributed to rheumatoid arthritis (RA) treatment from a patient's perspective using real-world patient follow-up data from hospitals' electronic database.

    METHODS: A prospective 1-year study was conducted in rheumatology clinics of tertiary care hospitals of Karachi, Pakistan. Cost-of-illness methodology was used and all patient data related to costs of rheumatologist visits, physical therapy sessions, medications, assistive devices and laboratory investigations were obtained directly in printed hardcopies from patient electronic databases using their medical record numbers. Transportation cost was calculated from patient-reported log books. Data were analyzed through IBM SPSS version 23. Patients were asked to sign a written consent and the study was ethically approved.

    RESULTS: The mean age of patients (N = 358) was 48 years. Most patients (73.7%) were female, married (86%) and had basic education (71.8%). Average cost of rheumatologist visits was PKR 11 510.61 (USD: 72.05) while it was PKR 66 947.37 (USD: 419.07) for physical therapy sessions. On average, medicines and medical devices costs were estimated at PKR 10 104.23 (USD: 63.25) and PKR 7848.48 (USD: 49.13) respectively. Cost attributed to diagnostic and laboratory charges was PKR 1962.12 (USD: 12.28) and travel expense was PKR 6541 (USD: 40.95). The direct expenditure associated with managing RA was PKR 37 558 (USD: 235.1). All costs were reported per annum.

    CONCLUSION: Patient with RA in Pakistan pay a considerable amount of their income for managing their condition. Most patients have no provision for insurance which is a need considering the nature of the disease and associated productivity loss that would significantly lower income as the disease progresses.

    AIM: To update recommendations based on current best evidence concerning the treatment of rheumatoid arthritis (RA), focusing particularly on the role of targeted therapies, to inform clinicians on new developments that will impact their current practice.

    MATERIALS AND METHODS: A search of relevant literature from 2014 to 2016 concerning targeted therapies in RA was conducted. The RA Update Working Group evaluated the evidence and proposed updated recommendations using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach, to describe the quality of evidence and strength of recommendations. Recommendations were finalized through consensus using the Delphi technique.

    RESULTS: This update provides 16 RA treatment recommendations based on current best evidence and expert clinical opinion. Recommendations 1-3 deal with the use of conventional synthetic disease-modifying antirheumatic drugs. The next three recommendations (4-6) cover the need for screening and management of infections and comorbid conditions prior to starting targeted therapy, while the following seven recommendations focus on use of these agents. We address choice of targeted therapy, switch, tapering and discontinuation. The last three recommendations elaborate on targeted therapy for RA in special situations such as pregnancy, cancer, and major surgery.

    CONCLUSION: Rheumatoid arthritis remains a significant health problem in the Asia-Pacific region. Patients with RA can benefit from the availability of effective targeted therapies, and these updated recommendations provide clinicians with guidance on their use.

    Excessive release of kinin (BK) in the synovial fluid can produce oedema, pain and loss of functions due to activation of B1 and B2 kinin receptors. Activation of the kinin forming system could be mediated via injury, trauma, coagulation pathways (Hageman factor and thrombin) and immune complexes. The activated B1 and B2 receptors might cause release of other powerful non-cytokine and cytokine mediators of inflammation, e.g., PGE2, PGI2, LTs, histamine, PAF, IL-1 and TNF, derived mainly from polymorphonuclear leukocytes, macrophages, endothelial cells and synovial tissue. These mediators are capable of inducing bone and cartilage damage, hypertrophic synovitis, vessel proliferation, inflammatory cell migration and, possibly, angiogenesis in pannus formation. These pathological changes, however, are not yet defined in the human model of chronic inflammation. The role of kinins and their interacting inflammatory mediators would soon start to clarify the detailed questions they revealed in clinical and experimental models of chronic inflammatory diseases. Several B1 and B2 receptor antagonists are being synthesized in an attempt to study the molecular functions of kinins in inflammatory processes, such as rheumatoid arthritis, periodontitis, inflammatory diseases of the gut and osteomyelitis. Future development of specific potent and stable B1 and B2 receptor antagonists or combined B1 and B2 antagonists with y-IFN might serve as a pharmacological basis for more effective treatment of joint inflammatory and related diseases.

    The mechanisms causing inflammation in rheumatoid arthritis (RA) are not yet clearly known. They may be associated with different types of inflammatory cells and probably numerous mediators (SHARMA and MOHSIN 1990). Nowadays, the platelet activating factor (PAF) is discussed as an important mediator in RA.

    Owing to its intricate autoimmune pathophysiology and significant risks of progression to other rheumatic co-morbidities (i.e., osteoporosis and osteoarthritis), a plausible therapeutic regimen is mandatory for early-stage management of rheumatoid arthritis (RA). Nevertheless, the conventional therapeutic agents particularly the corticosteroids and disease-modifying anti-rheumatic drugs (DMARDs) have shown grander success in the treatment of RA; however, long-term use of these agents is also associated with serious adverse events. To combat these issues and optimize therapeutic efficacy, nanotechnology-based interventions have been emerged as viable option. While, nanomedicines signposted superiority over the conventional pharmacological moieties; there are still many pharmacokinetic and pharmacodynamic challenges to nanomedicines following their intravenous or intra-articular administration. To circumvent these challenges, significant adaptations such as PEGylation, surface conjugation of targeting ligand(s), and site- responsive behavior (i.e., pH-, biochemical-, or thermal-responsiveness) have been implemented. Besides, multi-functionalization of nanomedicines has been emerging as an exceptional strategy to overcome pharmacokinetic challenges, improve targetability to inflamed synovium, maximise internalisation into the activated macrophages, and improved therapeutic outcomes for treatment of RA. Therefore, this review aims to conceptualize and recapitulate the substantial evidences regarding the pharmacokinetic and pharmacodynamic superiority of multi-functionalized nanomedicines over the naked nanomedicines for site-selective targeting to inflamed synovium and rational treatment of RA and other rheumatic co-morbidities. Pharmaceutical sustainability of the multi-functionalized nanomedicines for improved biocompatibility, profound interaction with the targeting tissue/cells/sub-cellular domain, and diminished systemic toxicity has also been pondered.

    Nanotheranostics is one of the biggest scientific breakthroughs in nanomedicine. Most of the currently available diagnosis and therapies are invasive, time-consuming, and associated with severe toxic side effects. Nanotheranostics, on the other hand, has the potential to bridge this gap by harnessing the capabilities of nanotechnology and nanomaterials for combined therapeutics and diagnostics with markedly enhanced efficacy. However, nanomaterial applications in nanotheranostics are still in its infancy. This is due to the fact that each disease has a particular microenvironment with well-defined characteristics, which promotes deeper selection criteria of nanomaterials to meet the disease needs. In this review, we have outlined how nanomaterials are designed and tailored for nanotheranostics of cancer and other diseases such as neurodegenerative, autoimmune (particularly on rheumatoid arthritis), and cardiovascular diseases. The penetrability and retention of a nanomaterial in the biological system, the therapeutic strategy used, and the imaging mode selected are some of the aspects discussed for each disease. The specific properties of the nanomaterials in terms of feasibility, physicochemical challenges, progress in clinical trials, its toxicity, and their future application on translational medicine are addressed. Our review meticulously and critically examines the applications of nanotheranostics with various nanomaterials, including graphene, across several diseases, offering a broader perspective of this emerging field.

    Porphyromonas gingivalis (P. gingivalis) is the primary periodontal pathogen involved in protein citrullination, which triggers the production of anti-cyclic citrullinated peptide (anti-CCP) antibodies, exacerbating rheumatoid arthritis (RA). This study aims to evaluate the amount of P. gingivalis and its association with anti-CCP antibodies in RA patients with periodontitis. This cross-sectional study involves 100 RA patients with a mean age of 52.36 (SD 13.90) years. Smokers and patients with other uncontrolled systemic diseases were excluded. Disease Activity Score-28 (DAS-28) was used to determine RA disease severity. Periodontal parameters were examined to determine periodontal status. Subsequently, plaque samples were collected from the subgingival periodontal pocket for assessment of P. gingivalis bacterial load using the loop-mediated isothermal amplification method. Blood samples (5 ml) were obtained from all participants to analyse anti-CCP antibody levels. Data was analysed by using SPSS version 24.0. Most participants were female (85.0%) and had low RA disease severity (62%). The mean RA disease duration was 7.77 (SD 6.3) years, with a mean DAS-28 of 3.17 (SD 1.0). Forty-seven per cent of participants had periodontitis, but all periodontal parameters were not associated with RA disease activity (P = 0.38). P. gingivalis bacterial load ranged from 10 to 109 copies/μl. Fifty-five per cent of the collected samples showed positive anti-CCP antibody levels, but no significant association was observed with the P. gingivalis bacterial load (P = 0.58). Considering the study's limitations, although periodontitis is prevalent among RA patients, there is a lack of association between P. gingivalis bacterial load and anti-CCP antibody levels, which should be investigated further.

    Objectives: Anti-cyclic citrullinated peptide (CCP) antibody has recently been used in the classification
    of rheumatoid arthritis (RA). This antibody is more specific than rheumatoid factor (RF) for the diagnosis of RA. The study objectives were to determine the sensitivity, specificity, positive and negative predictive values of anti-CCP in RA diagnosis.
    Methodology: Eighty RA patients and 80 non-RA individuals were included in the study. Blood was collected from both arms of study subjects and tested for anti-CCP and RF antibodies. Relevant clinical information and laboratory profiles of the RA patients were evaluated using patients’ medical records and Integrated Laboratory Management System (ILMS), respectively.
    Results: The sensitivity and specificity of anti-CCP were 35% and 100% respectively. The positive and
    negative predictive values were 100% and 61%, respectively. Positive anti-CCP was found significantly
    associated with multiple joint pain (p < 0.001) and hand’s joints pain (p=0.01), symmetrical joints
    involvement (p=0.015) and high CRP value (p < 0.001). Anti-CCP was also found to have positive association with RF (p < 0.001).
    Conclusion: Anti-CCP is highly specific for the diagnosis of RA. High positive predictive value should be taken into consideration for effective treatment.

    We investigated the association between cigarette smoking and the risk of developing rheumatoid arthritis (RA) in the Malaysian population. A total of 1,056 RA patients and 1,416 matched controls aged 18-70 years within a defined area of Peninsular Malaysia were evaluated in a case-control study between August 2005 and December 2009. A case was defined as a person with early diagnosed RA using the 1987 American College of Rheumatology criteria for RA. Controls were randomly selected matched for sex, age, and residential area. Cases and controls answered a questionnaire on a broad range of issues, including lifestyle factors and smoking habits wherein current and former smoking was classified as ever-smoking. The presence of anti-citrullinated peptide antibodies (ACPA) was determined for cases and controls. We found that ever-smokers had an increased risk of developing ACPA-positive RA [odds ratio (OR) = 4.1, 95% confidence interval (CI) 1.9-9.2] but not ACPA-negative RA (OR = 0.7, 95% CI 0.3-2.0), compared with never-smokers. A significant dose-response relationship between cumulative dose of smoking and risk of ACPA-positive RA was observed (<20 pack-years OR = 3.3, 95% CI 1.1-9.8; at least 20 pack-years OR = 5.2, 95% CI 1.6-17.6). Hence, smoking is associated with an increased risk of ACPA-positive RA in the Malaysian population, in which the genetic context is similar to several other Asian countries.

    Aim: Autoantibodies against cyclic citrullinated peptide (anti-CCP) are considered to be a sensitive and specific marker for rheumatoid arthritis (RA). This study evaluated the diagnostic and analytical performances of the automated anti-CCP assay.
    Materials and Method: Sera from 80 patients with established RA, 65 from other rheumatic diseases (non-RA) and 55 from healthy controls were studied using second generation anti-CCP. Rheumatoid factor (RF) was also assayed in each sample, and the results were compared to the anti-CCP fi ndings. Serum pools were used to determine the precision and linearity.
    Results: At a cut-off of 7.4 U/ml for anti-CCP, the sensitivity and specificity for RA were 65% and 98% respectively. RF had a sensitivity of 58% and a lower specifi city of 93 % than anti-CCP. Conclusion: The high specificity of the assay suggests that anti-CCP is useful in the diagnosis of rheumatoid arthritis and in our cohort of study population anti-CCP exhibits a better diagnostic value than RF. A considerable proportion (28%) of RF-negative RA patients were anti-CCP positive. Based on analytical performance of the assay, we conclude that full automation and high throughput features of AxSYM makes it an ideal platform for routine testing of anti-CCP.

    AIMS: The aim of this study was to evaluate the left ventricular (LV) diastolic dysfunction in rheumatoid arthritis (RA) patients without clinically evident cardiovascular manifestations and to estimate whether there is any correlation between RA disease severity and disability and LV diastolic dysfunction.
    METHODS: The study was a cross-sectional study involving 53 patients (47 female and 6 male) with RA without clinically evident heart disease and 53 healthy subjects (47 female and 6 male) who served as a control group. Both groups were matched for age and sex. Echocardiographic and Doppler studies were conducted in all patients with RA and control subjects.
    RESULTS: Of 17 cardiac parameters assessed, only two were abnormal. None of the specific cardiac diastolic dysfunction parameters were significantly different in RA patients compared to the control group. There was no significant correlation between diastolic function values in RA patients and value of Disease Activity Score 28 (DAS-28) and value of Health Assessment Questionnaires Disability Index (HAQDI). Atrial (A) wave velocity was greater in RA patients compared to the control group (0.71 [0.58-0.83] vs. 0.61 [0.51-0.71]; P < 0.04). However, interventricular relaxation time (IVRT) ([73.08 ± 9.92 vs. 70.74 ± 9.02], P = 0.207), lower E/A ratio (1.27 [1.02-1.56] vs. 1.42 [1.20-1.68], P = 0.102), diastolic dysfunction parameters according to Redfield Classification (25 [47.2%] vs. 27 [50.9%] P = 0.56), diastolic dysfunction using E/A (P = 0.321) and tissue doppler imaging (E/E') (P = 0.148) were not different.
    CONCLUSION: Prevalence of diastolic dysfunction in the rheumatoid arthritis group (47.2%) was not different from controls (50.9%). LV diastolic function had no significant correlation with RA disease severity and duration of disease.

    The aim of our study is to describe the pattern, clinical features, treatment regimes, and disease activity among the patients treated for rheumatoid arthritis (RA) in the Sarawak General Hospital. We performed a cross-sectional study of all patients with a diagnosis of RA who received treatment at the General Medical Clinic and the Rheumatology Clinic in Sarawak General Hospital over a 1-year period from 1st June 2006 to 31st May 2007. Demographic data, clinical features, and disease activity of all 154 patients were collected for statistical analysis. Rheumatoid arthritis afflicts all the major racial groups in Sarawak including the native population. Our patients have a mean disease duration of 5.4 years (SD 5.69) and a mean duration of delay in diagnosis RA and initiation of disease-modifying antirheumatic drug (DMARD) treatment of 42.9 months (SD 60.1). They have a low rate of interstitial lung disease (6.5%) and rheumatoid nodules (4.5%). Rheumatoid factor was positive in 65.5% of our patients. They have a mean Disease Activity Score (DAS) 28 score of 4.28 (SD 1.33). Only 12.5% of our patients are in remission with DAS 28 < 2.6 and 30.9% of our patients are having high disease activity with DAS 28 > 5.1. Despite the high usage of DMARDs in Sarawak (>80%), our patients have severe disease with high disease activity indices. This is most likely due to delay in diagnosis and initiating DMARDs in RA patients in Sarawak.

    Rheumatoid arthritis (RA) is a chronic joint disease of undetermined cause that is associated with significant disability. Low-grade fever, anemia, and weight loss are recognized extra-articular features associated with increased disease activity. Weight loss and cachexia are well-established features of RA. The mechanism behind weight loss in RA is not known and may be multifactorial. Reduced energy intake and hypermetabolism are the major two factors frequently implicated in the etiology of RA cachexia. One would expect the effect of the above two factors to be highest during increased disease activity and lowest during remission. The purpose of this study was: (a) to establish whether in RA patients changes in body composition mirror changes in disease activity, (b) to investigate the relation between the energy expenditures and weight loss, (c) to examine the dietary energy intake and its role in weight loss in RA patients, and (d) to investigate the relation between the cytokine interleukin (IL)-6 and other variables including resting energy expenditure (REE), body composition, and acute phase reactants. Fourteen patients with RA were age-, sex-, and race-matched with 14 controls from patients with noninflammatory diseases/soft tissue rheumatism. The measurements included the following: disease activity assessment, anthropometric measurements, indirect calorimetry, and measurements of dietary intake. Blood was collected to measure the acute-phase reactants and IL-6 levels. We demonstrated that loss of fat-free mass (FFM) might accelerate during times of increased disease activity and is only partially restored during periods of reduced disease activity. This probably means that the extent of cachexia in RA patients is determined by the frequency and intensity of disease activity (flare) for a given disease duration. Hypermetabolism with increased REE was more evident during increased disease activity. Hypermetabolism in the face of increased energy intake continued to cause loss of the FFM. Interleukin-6 correlates with increased REE and erythrocyte sedimentation rate. There was no direct association between IL-6 level and low FFM. We conclude that loss of FFM is common in RA, cytokine production in RA is associated with altered energy metabolism, and preservation of FFM is important in maintaining good quality of life in patients with RA.

    Survivin is a biomarker of cancer known for its anti-apoptotic and cell-cycle regulating properties. In the context of non-cancer pathology, high levels of survivin may be measured in blood and synovial fluid of patients with rheumatoid arthritis (RA) and associate with early joint damage and poor therapy response. The aim of the study was to investigate the value of survivin measurements in blood for diagnosis of RA in the frame of the Malaysian epidemiological investigation of rheumatoid arthritis (MyEIRA) study. The study enrolled RA patients from eight rheumatology centres in Peninsular Malaysia. The healthy controls matched by age, gender and ethnicity were recruited on the community basis from the residential area of the patients. Levels of survivin were measured in blood of RA patients (n = 1233) and controls (n = 1566) by an enzyme-linked immuno-sorbent assay (ELISA). The risk for RA was calculated as odds ratio (OR) and 95% confidence intervals in the individuals with high levels of survivin. The risk was calculated in relation to antibodies against cyclic citrullinated peptides (ACPA), detected by ELISA and HLA-DRB1 shared epitope (SE) alleles, identified by the polymerase chain reaction using sequence specific oligonucleotide method. High levels of survivin were detected in 625 of 1233 (50.7%) RA cases and in 85 of 1566 (5.4%) controls, indicating its high specificity for RA. Survivin was association with an increase in RA risk in the patients having neither SE-alleles nor ACPA (OR = 5.40, 95% CI 3.81-7.66). For the patients combining survivin, SE, and ACPA, the estimated risk for RA was 16-folds higher compared to the survivin negative patients with SE and ACPA(OR = 16.21, 95% CI 5.70-46.18). To conclude, detection of survivin in blood provides a simple test to improve diagnostic and to increase predictability for RA.

    Rheumatoid arthritis (RA) is the most common chronic systemic autoimmune disease worldwide. Although incurable, there are available therapies to effectively control the disease activity and minimize the joint damage. Numerous cytokines, enzymes and other forms of proteins have been implicated in the disease process of RA. In general, pharmacological therapies in RA target cytokine pathways. Despite a wide variety of disease modifying antirheumatic drugs (DMARD), a significant proportion of patients remain refractory to the available therapies. Hence, the search for newer drugs with different modes of actions is an ongoing process. The present review aimed to explore novel therapeutic targets in RA based on data from the literature. Inhibitors of spleen tyrosine kinase, choline kinase, galectin 3 and hypoxia-inducible factor may have a promising role in the
