Background: Rheumatoid Arthritis (RA) is one of the known Autoimmune diseases in patients with age group of 25 to 60. A significant aspect of disease development should be Reactive Oxygen Species (ROS). Few studies have shown an association between oxidative stress and RA disease activity. This study was therefore intended to examine whether there is a link between oxidative stress and disease activity. Methods and Materials: This case-control study on 120 individuals was conducted. In accordance with the Disease Activity Score (30) were healthy controls with 90 RA patients in mild (30), moderate (30) and severe (30). Malondialdehyde Measured Lipid Per Oxidation (MDA). Antioxidant enzyme activities such as Superoxide Dismutase (SOD), Catalase (CAT) and glutathione peroxidase (GPX) have been also measured. A correlation coefficient was also used to evaluate the strength of the link between oxidative stress and activity of the illness. Results: the MDA levels in all the RA subgroups were substantially higher than those in the control group, but the activity of antioxidant enzymes was significantly lower. Between Malondialdehyde Measured Lipid Per Oxidation (MDA) and Disease Activity score of 28 RA patients (DAS28) there were positive correlations. Conclusion: Significant increase in RA patients' lipid per oxidization supports the role of oxidative stress in RA aetiology and the usage of MDA for disease control.

Abstract Background. Oxidative stress may play an important role in rheumatoid arthritis (RA) etiopathogenesis. The thiol group is a very strong antioxidant. In this study, we aimed to investigate the presence of oxidative stress in patients with RA by evaluating thiol/disulfide homeostasis. Material and methods. A total of 50 female RA patients and 50 healthy female controls were included in this study. Thiol and disulfide values were calculated utilizing novel methods. Results. Native thiol (p < 0.001) and total thiol (p < 0.001) levels of RA patients were significantly lower compared to values in the control group. However, the disulfide (p < 0.001) levels of RA patients were strongly higher than in healthy individuals. A negative correlation was found between thiol and disease activity score-28 among the patients, whereas a positive correlation was found between disulfide and disease activity score-28 among the patients. Conclusion. We found that the thiol–disulfide rate deteriorated in RA patients, with the proportion of disulfide increasing. There is a strong correlation between the decrease in thiol levels, increase in disulfide levels and the disease activity scores.

The Impact

Rheumatoid arthritis (RA) is considered as an autoimmune-related condition in which the overproduction of pro-inflammatory cytokines leads to an inflammatory cascade. N-acetylcysteine (NAC) is a potent anti-inflammatory and anti-oxidant agent. We aimed to explore the impact of oral NAC on cytokines activities and clinical indicators in RA patients. In this placebo-controlled randomized double-blind clinical trial, 41 active RA patients were allocated in either NAC (600 mg, twice a day) or placebo group, as add-on therapy to the routine regimen, for 8 weeks. Disease activity score with an erythrocyte sedimentation rate (DAS28-ESR), and serum concentrations of interleukin (IL)-1β and IL-17 were assessed at baseline and end of the trial for all participants in the test and control groups. The reduction of the DAS28-ESR was higher considerably in the NAC group compared to that of the control group. No statistically significant differences were seen in the reduction of IL- 1β and IL-17 cytokines between the NAC and control groups. In addition, improvements in the patient global assessment, number of tender joints, number of swollen joints, and the ESR rates were in favor of the NAC group. Our findings reveal that NAC may have a beneficial effect on all of the clinical features of RA. However, non-significant variations in the IL-1β and IL-17 levels suggest an alternative way of NAC effectiveness without influencing the measured cytokines. Nevertheless, these results need to be confirmed by further investigations.

ObjectivesTo compare the efficacy of disease activity score in 28 joints (DAS28ESR)-driven therapy with anti-tumour necrosis factor (patients from the GUEPARD trial) and routine care in patients with recent-onset rheumatoid arthritis (patients of the ESPOIR cohort).ResultsAfter matching GUEPARD and ESPOIR patients on the basis of a propensity score and a 1:2 ratio, at baseline all patients had comparable demographic characteristics, rheumatoid factor, anticyclic citrullinated peptide antibody positivity and clinical disease activity parameters: erythrocyte sedimentation rate, C-reactive protein, mean DAS (6.26±0.87), Sharp/van der Heijde radiographic score (SHS), health assessment questionnaire (HAQ). Disease duration was longer in GUEPARD patients (5.6±4.6 vs 3.5±2.0 months, p<0.001). After 1 year, the percentage of patients in remission with an HAQ (<0.5) and an absence of radiological progression was higher in the tight control group (32.3% vs 10.2%, p=0.011) as well as the percentage of patients in low DAS with an HAQ (<0.5) and an absence of radiological progression (36.1% vs 18.9%, p=0.045). However, there was no difference in the decrease in DAS, nor in the percentage of EULAR (good and moderate), ACR20, ACR50 and ACR70 responses. More patients in the tight control group had an HAQ below 0.5 (70.2% vs 45.2%, p=0.005). Overall, pain, patient and physician assessment and fatigue decreased more in the tight control group. The mean SHS progression was similar in the two groups as was the percentage of patients without progression.ConclusionsIn patients with recent onset active rheumatoid arthritis, a tight control of disease activity allows more patients to achieve remission without disability and radiographic progression.

Background: Rheumatoid Arthritis (RA) is an autoimmune, chronic, and systematic disease. It affects joints and bones. The exact etiology of RA is still unclear. Varied genetic and environmental factors have been associated with the increased risk for RA. Overactivation of Toll-Like Receptors (TLRs) could initiate the development of autoimmune diseases including RA. Objective: The aim of the study was to evaluate TLR2 gene expression in rheumatoid arthritis patients and investigate its correlation with the disease activity. Materials and Methods: This study included 60 patients and 20 healthy individuals. The patients were diagnosed with RA according to the 2010 American College of Rheumatology/ European League Against Rheumatism criteria (ACR/EULAR). All included subjects did not have any joint disorders and /or autoimmune diseases. RA disease activity was determined by the disease activity score of 28 joints. Whole blood was collected from all participants. Total RNA extraction was done. TLR2 mRNA expression was assessed by reverse transcription-PCR (RT-PCR). Results: TLR2 mRNA expression was found to be significantly higher in RA patients compared to healthy controls. Also, a strong positive correlation was found between TLR2 expression level and the disease activity score. A non significant positive correlation was found between TLR2 expression and serum Rheumatoid Factor (RF) level. Conclusion: TLR2 pathway may have an important role in RA pathogenesis and could be a new biomarker for diagnosis and monitoring disease activity.

Background: Rheumatoid arthritis (RA) is a common progressive chronic inflammatory autoimmune disease which affects mostly small joints, causing pain, swelling, deformity, and disability. Although progress has been made in exploring RA nature, still there is a lot to know about the disease pathogenesis, diagnosis, and treatment. Aim of the Work: To investigate the role of serum anti-carbamylated protein antibodies and 14-3-3η in the diagnosis of RA compared to rheumatoid factor (RF), anti-CCP antibodies, and highfrequency musculoskeletal ultrasound used to assess the disease activity and joint damage. Methods: Serum anti-carbamylated protein antibodies and 14-3-3η were measured using ELISA in 61 RA patients and 26 normal controls. RA Disease Activity Score (DAS 28), X-ray and musculoskeletal ultrasound (hands and feet), carotid ultrasound (Intima-Media Thickness IMT) were used in assessing the RA disease. Results: Anti-carbamylated protein antibodies were significantly elevated in RA patients 4.5 (4.1- 8.9 U⁄ml) compared to the control 3.2(1.9- 4.3 U⁄ml) (p< 0.001) but 14-3-3η showed no significant difference. There was a significant positive correlation between anti-carbamylated protein antibodies, 14-3-3η levels and disease activity score assessed by DAS 28, increased IMT measured by carotid duplex, total synovitis and total erosion score were assessed by musculoskeletal ultrasound. There was no correlation between RF and anti-CCP antibodies. Anti-carbamylated protein antibodies were found to have 66.7% sensitivity and 85.2% specificity in RA diagnosis, while 14- 3-3η had 51.9% sensitivity and 72.1% specificity. Conclusion: Anti-carbamylated protein antibodies and 14-3-3η have a high sensitivity and specificity in RA diagnosis and had a correlation with the disease activity and joint damage.

There is limited data on the effect of the novel coronavirus disease (COVID-19) caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) on pediatric rheumatology. We examined the prevalence of antibodies against SARS-CoV-2 in children with juvenile idiopathic arthritis (JIA) and a negative history of COVID-19 and the correlation of the presence of these antibodies with disease activity measured by juvenile arthritis disease activity score (JADAS). In total, 62 patients diagnosed with JIA, under treatment with various antirheumatic drugs, and 32 healthy children (control group) were included. Serum samples were analyzed for inflammatory markers and antibodies and their state evaluated with the juvenile arthritis disease activity score (JADAS). JIA patients do not have a higher seroprevalence of anti-SARS-CoV-2 antibodies than healthy subjects. We found anti-SARS-CoV-2 antibodies in JIA patients who did not have a history of COVID-19. The study showed no unequivocal correlation between the presence of SARS-CoV-2 antibodies and JIA activity; therefore, this relationship requires further observation. We also identified a possible link between patients’ humoral immune response and disease-modifying antirheumatic treatment, which will be confirmed in follow-up studies.
