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.

Rheumatoid arthritis (RA) is a highly debilitating chronic inflammatory autoimmune disease most prevalent in women. The true etiology of this disease is complex, multifactorial, and is yet to be completely elucidated. However, oxidative stress and lipid peroxidation are associated with the development and pathogenesis of RA. In this case, oxidative damage biomarkers have been found to be significantly higher in RA patients, associated with the oxidation of biomolecules and the stimulation of inflammatory responses. Lipid peroxidation is one of the major consequences of oxidative stress, with the formation of deleterious lipid hydroperoxides and electrophilic reactive lipid species. Additionally, changes in the lipoprotein profile seem to be common in RA, contributing to cardiovascular diseases and a chronic inflammatory environment. Nevertheless, changes in the lipid profile at a molecular level in RA are still poorly understood. Therefore, the goal of this review was to gather all the information regarding lipid alterations in RA analyzed by mass spectrometry. Studies on the variation of lipid profile in RA using lipidomics showed that fatty acid and phospholipid metabolisms, especially in phosphatidylcholine and phosphatidylethanolamine, are affected in this disease. These promising results could lead to the discovery of new diagnostic lipid biomarkers for early diagnosis of RA and targets for personalized medicine.

Background:Bone is a target in many inflammatory rheumatic diseases such as rheumatoid arthritis (RA). It has been supposed that an atherogenic lipid profile could be associated with lower bone mineral density (BMD) and vertebral fractures (VF).Objectives:We aimed to evaluate the relationship between the lipid profile, BMD and the presence of VF in RA patients.Methods:A cross sectional study was conducted in a population of 169 established RA. In each subject we evaluated the body mass index (BMI), tobacco use, alcohol consumption, presence of diabetes and high blood pression, lipid profile (total cholesterol (TC), High density lipoprotein cholesterol (HDLc), low density lipoprotein cholesterol (LDLc), triglycerides (TG), and VF. RA characteristics were also assessed (disease duration, disease activity score (DAS), auto antibodies, corticosteroid intake, and secondary sjogren’s syndrome). BMD was measured by dual energy X-ray absorptiometry (DXA) in lumbar spine and femoral neck. Logistic and linear regression were performed with SPSS 20, both BMD and VF were assessed as dependent variables.Results:The mean age was 55.5±11.9 years, with a female predominance (152 women). The average BMI was 26.79 ± 5.36. We had 24.3 % of hypertensive patients and 16.6 % of diabetics. The average lipid concentrations were 4.39±1 mmol/L for TC, 1.293±0.36 mmol/L for HDLc, 2.74±0.80 mmol/L for LDLc and 1.25±0.62 mmol/L for TG. At the linear regression there was no correlation between plasma lipid concentrations and BMD, whether at the lumbar spine or the femoral neck. However we found a significant correlation between VF and high TC concentrations (p=0.043, OR: 2.864, 95% IC [1.036-7.922]). At the multivariate regression, high TC levels were still associated with VF, adjusted in BMI, age and the duration of corticosteroid use (p=0.006, OR: 6.07, 95% CI[1.69- 21.77]). The same finding was observed between high concentrations of HDLc and the prevalence of VF adjusted in the same variables (p=0.006, OR: 197.01, 95% CI [4.64-8363.51]).Conclusion:Although there was no relation between lipid plasma levels and BMD in our population. There was a significant association between high concentrations of TC, HDLc and the prevalence of VF.Disclosure of Interests:None declared
