The aim of this study was to evaluate the involvement of TNF-αand insulin resistance (IR) in the inflammatory process, oxidative stress, and disease activity in patients with rheumatoid arthritis (RA). This cross-sectional study included 270 subjects (control group,n=97) and RA patients (n=173). RA patients were divided into four groups: the first group without IR and not using antitumor necrosis factor-α(TNF-) (G1, IR− TNF−); the second group without IR and using anti-TNF-α(G2,IR-TNF+); the third group with IR and not using anti-TNF-α(G3, IR+TNF-); and the fourth group with IR and using anti-TNF-α(G4, IR+ TNF+). G3 and G4 had higher (p<0.05) advanced oxidation protein products (AOPPs) and oxidative stress index (OSI) compared to G1. G4 group presented higher (p<0.05) AOPPs and OSI than G2. TRAP was significantly lower in G3 compared to G1. Plasma TNF-αlevels were significantly higher in G4 and G2 compared to G1 (p<0.0001) and G3 (p<0.0001andp<0.01, resp.). The presence of insulin resistance was robustly associated with both oxidative stress and TNF-αlevels. More studies are warranted to verify if IR can be involved in therapeutic failure with TNF-αinhibitors. This trial is registered with Brazilian Clinical Trials Registry Register numberRBR-2jvj92.

Objectives: Objective of our study is to measure the concentration and role of Malondialdehydein determining the oxidative stress in rheumatoid arthritis patients in comparison with healthy individuals. Study Design: Cross sectional study. Setting: Department of physiology Gujranwala Medical College and Shalamar Medical College, Lahore. Period: From October 2016 to October 2017. Methodology: 180 patients of age 49 to 70 years of either gender. The approval for conducting experimental study was taken from ethical committee and consent information was taken from the patient on prescribed Performa. Data was analyzed on SPSS Version 23 related to study. Continuous variables were presented as mean and standard deviation like age and serum MDA concentration. Categorical variables were presented as numbers and percentages like gender. Post operative chi square test was applied and p- value less than or equal to 0.05 was considered as significant. Results: Total 180 person (n=180) of either genderwere included in this study. The study group was divided into two equal groups. Group A (RA group) consists of 90 patients (n=90) based on clinically and laboratory based criteria while group B (control group) consists of 90 (n=90) normal healthy individuals. The serum MDA levels in the RA patients were 3.97±1.03 nmoles/ml and it was 1.59±0.32 n moles/ml in control patients. The difference was statistically significant (t=20.87, p=0.001). Conclusion: The observations of our study showed statistically significant raised serum Malondialdehyde level as compared to control group which shows that raised serum MDA is an indicator of oxidative stress in rheumatoid arthritis patients.

Aims: The etiopathogenesis of Rheumatoid Arthritis (RA) is not clearly understood. However, the role of the cytokines takes an important part in this mechanism. We aimed to bring a new approach to the concept of 'remission' in patients with RA. Background: RA is a chronic, autoimmune, inflammatory disease that involves small joints in the form of symmetrical polyarthritis and progresses with exacerbations and remissions. Pain, swelling, tenderness and morning stiffness are typical of the joints involved. Although it is approached as a primary joint disease, a wide variety of extra-articular involvements may also occur. It is an interesting pathophysiological process, the exact cause of which is still unknown, with many environmental, genetic and potentially undiscovered possible factors in a chaotic manner. Objective: In this cross-sectional study, sedimentation rate (ESR), C- Reactive protein (CRP), Tumor necrosis factor (TNF)-α, soluble-TNF-α receptor (TNF-R), Interleukin (IL)-1B and IL-10 were measured in three groups which were healthy volunteers, patients with RA in the active period, and patients with RA in remission. Disease activity score-28 (DAS-28) was calculated in active RA and RA in remission. Methods: This study included 20 healthy volunteers, 20 remission patients with RA and 20 active RA patients. Venous blood samples were collected from patients in both healthy and RA groups. Results: RA group consisted 43 (71.6%) female and 17 (28.4%) male. Control group consisted 11 (55%) female and 9 (45%) male. TNF-R was significantly high only in the active group according to the healthy group (p=0.002). IL-10 was significantly high in active RA according to RA in remission (p=0.03). DAS-28 was significantly high in active RA according to RA in remission (p=0.001). In the active RA group, ESR and TNF-R had a positive correlation (r:0.442; p=0.048). In the active RA group, there was also a positive correlation between TNF-R and CRP (r:0.621; p=0,003). Both healthy and active RA group had significant positive correlation between ESR and CRP (r: 0.481; p=0.032 and r: 0,697; p=0,001 respectively). Conclusion: TNF-R can be the main pathophysiological factor and a marker showing activation. TNF-R can be very important in revealing the effect of TNF on the disease and the value of this effect in the treatment and ensuring the follow-up of the disease with CRP instead of ESR in activation.

Background:Rheumatoid Arthritis (RA) is one of the risk factors for the calculation of the 10 years fracture probability assessed by the FRAX tool.Objectives:The aim was to study the association of disease activity and the 10 year fracture risk probability by the FRAX tool in our RA patients and their impact on fracture prevalence.Methods:Cross-sectional study of the association FRAX and disease activity score (DAS 28 CRP) was designed. Patients with RA were included. Mean DAS was calculated for each patient adjusted on his follow-up duration. Data about patients (demographic, disease characteristics and fracture assessment) were collected. The 10 year fracture risk probability for major osteoporotic fracture was calculated with and without BMD (bone mineral density) using the FRAX tool for Morocco. Descriptive analysis and regressions were performed with SPSS.20. p<0.05 was considered significant.Results:One hundred and ninety nine RA patients were included with mean age of 55.5±12 years. Women represented 91% and 40.1% had osteoporosis. Remission was observed in 86.4% with 95.5% taking methotrexate. 17.1% had vertebral fractures. FRAX and DAS were associated (p=0.03), and both explained vertebral fracture (VF) prevalence. When adjusted on disease parameters, FRAX with and without BMD explained the vertebral prevalence (p=0.02, OR=1.09[1.01-1.19]). However, age remains the only predictor of VF when adjusted on osteoporosis factors (DAS28CRP, menopause, BMI, smoking, diabetes, gender, steroid use, HAQ) and FRAX BMD.Conclusion:Persistent disease activity was associated to high 10 year fracture risk probability calculated by the FRAX tool in RA.Disclosure of Interests:None declared

Abstract Background This study aimed to measure the serum and synovial interleukin (IL)-37 levels in rheumatoid arthritis (RA) patients compared to patients with primary knee osteoarthritis (PKOA) and healthy controls and to detect its relation to RA disease activity. Results This cross-sectional study included 50 RA patients with a mean age of 40.24 ± 8.62 years, 50 patients with PKOA with a mean age of 56.69 ± 4.21, and 40 healthy controls with a mean age of 41.75 ± 7.38 years. The mean serum IL-37 level in the RA patients (382.6 ± 73.97 pg/ml) was statistically significantly (P < 0.001) the highest among the studied groups; however, it showed a non-significant difference between the PKOA patients (70.38 ± 27.49 pg/ml) and the healthy controls (69.97 ± 25.12 pg/ml) (P > 0.94). Both serum and synovial IL-37 levels were significantly positively correlated with disease activity scores (r = 0.92, P< 0.001 and r = 0.85, P < 0.001), tender joint counts (r = 0.83, P < 0.001 and r = 0.82, P < 0.001 ), swollen joint counts (r = 0.72, P < 0.001 and r = 0.60, P < 0.001), visual analog scale (r = 0.82, P < 0.001 and r = 0.82, P < 0.001), erythrocyte sedimentation rate (r = 0.75, P < 0.001 and r = 0.65, P < 0.001), and C-reactive protein (r = 0.93, P < 0.001 and r = 0.79, P < 0.001), respectively. Conclusion Serum and synovial IL-37 were significantly elevated in the RA patients, and they were closely correlated. Being less invasive, the serum IL-37 could be a marker of disease activity and could reflect the effective disease control by drugs. Having an anti-inflammatory effect could not suggest IL-37 as the key player to control inflammation alone, but its combination with other anti-proinflammatory cytokines could be investigated.

Objective. The genes for killer-cell immunoglobulin-like receptors (KIRs) have been cloned and their functions and expression in patients with rheumatoid arthritis (RA) have been partially clarified. However, the correlation between their expression and disease activity has not been analyzed in patients with RA. Thus, we measured KIR expression on lymphocytes in patients with RA, and assessed the correlation between KIR expression and disease activity.Patients and Methods. In the cross-sectional study, 15 patients (9 females and 6 males) who fulfilled the diagnostic criteria for RA were assessed. In the longitudinal study, patients who were followed-up for 3 months were assessed. CD158a/b expression on peripheral blood mononuclear cells (PBMC) of RA patients was analyzed using flow cytometry.Results. No significant correlation between KIR expression and CRP, ESR, or IgM-RF was observed. There was no remarkable change in the expression of KIRs between the baseline and after 3 months. Additionally, in the 5 patients whose expression of KIRs particularly changed, the time-related changes in the expression of KIRs were independent from those of inflammation parameters and IgM-RF.Conclusion. There was no correlation between KIR expression and disease activity; therefore, the clinical use of KIR expression should be limited, while unnatural KIR expression may be involved in the pathogenesis of RA, but not a recruitment of chronic inflammation to induce joint damage.
