Rheumatoid Arthritis Activity

Background:Production of antibodies to ceruloplasmin (CP) in rheumatoid arthritis is an issue that has not been studied well enough. It was not by chance that this copper–containing alpha 2-glycorpoteid of blood plasma showing multienzymatic properties was chosen as an object of investigation. Data on the content and activity of CP in the blood of rheumatoid arthritis patients are contradictory, which has to do with different approaches to selection of patients and different measuring methods.Objectives:Improving diagnosis of rheumatoid arthritis by determination of antibodies to CP as well as its amount and enzymatic activity.Methods:We studied the serum from 30 apparently healthy individuals, and 108 rheumatoid arthritis patients. Antibodies to CP were determined by enzyme immunoassay using immobilized granulated antigen preparations (modification by Gontar et al, 2002). The amount of CP was determined by enzyme immunoassay according to the method of I.S. Kuzmina et al (1991) using commercial diagnostic agent manufactured by Mechnikov Research Institute for Vaccines and Sera.Results:Enzyme immunoassay showed a mean level of CP antibodies in donor sera of 0,020±0,006 optical density units. The level of normal values of specific antibodies determined as M±2σ included an extinction value in the range 0 – 0,086. The mean value of oxidase activity and the amount of CP in healthy people was 716±26,3 and 921±32 ng/ml, correspondingly. In the process of study we revealed a reliable increase in CP antibody count, the activity and amount of CP in patients with rheumatoid arthritis while in all cases the parameters under study correlated with the degree of disease activity (p<0,05): at activity degree I CP antibodies were 0,098±0,011; CP activity was 954±48,1; CP amount was 1292±73,4. At activity degree II CP antibodies were 0,138±0,007; CP activity was 1163±39,6; CP amount was 1763±69,3. At activity degree III, CP antibodies were 0,182±0,015; CP activity was 1368±89,5; CP amount was 1794±102,8. After a course of hospital treatment was completed, we noted a reliable decrease in the activity and amount of CP (at degree I of rheumatoid arthritis activity p<0,001, at degree II of rheumatoid arthritis activity p<0,01for both parameters; at degree III, p<0,05) compared with baseline findings. A decrease in CP antibodies shows decelerated dynamics, especially in patients with pronounced disease activity, which indicates severe disorders in the immunity that cannot be cured completely within 30 – 40 days of hospital treatment course.Conclusion:Determination of CP antibodies, as well as quantitative content of CP and its oxidase activity can serve as indicators of the activity of rheumatoid arthritis, as well as an accessory criterion of the effectiveness of administered therapy.Disclosure of Interests:None declared

Background/Aim. Many arguments prove the pathophysiologic role of histamine in the process of remodeling and joint destruction in rheumatoid arthritis. The aim of our study was to find out if there was a relation between histamine concentration in synovial fluid and blood with clinical expression of disease activity. Methods. Histamine concentration in synovial fluid and blood was determinated in 19 patients with rheumatoid arthritis. Histamine concentration measurement was based on the Shore's fluorometric method. Histamine index (HI) was evaluated as a ratio between histamine concentration in synovial fluid and blood. Disease activity score, DAS 28 (3), with three variables (erythrocyte sedimentation rate, the number of swelled joints and the number of tender joints) was also evaluated. Results. Our results showed that there was no significant difference in concentration of histamine in synovial fluid and blood related to disease activity. However, there was a significant difference in the histamine index which was increased proportionally with disease activity. Conclusion. Our study indicates that histamine index could be useful in estimation of rheumatoid arthritis activity.

Introduction. Cardiovascular complications are more often observed in patients with rheumatoid arthritis. Available cardiovascular risk scales were developed for general population and provide in sufficiently adequate assessment of the cardiovascular event likelihood. Studying the risk factors in rheumatoid arthritis patients is necessary for timely diagnosis and prevention.Objective: To analyze the incidence of atherosclerotic lesions in the brachiocephalic arteries in patients with rheumatoid arthritis and associations of this pathology with cardiovascular risk factors.Material and Methods. Two hundred and twelve Caucasian patients with rheumatoid arthritis (age of 58.0 years [48.3; 65.0]; Disease Activity Score-28 of 4.96 [3.86; 5.85]) were included in our study. Patients had American College of Rheumatology-defined rheumatoid arthritis (1987 classification criteria). The ratio of women to men was 5.8 to 1. General clinical examination of patients, the identification of traditional cardiovascular risk factors, and the determination of disease activity were performed. The atherosclerotic progression was assessed by ultrasonography with carotid intima-media thickness measurement and atherosclerotic plaque detection. All patients gave written informed consent before enrollment into the study.Results. Atherosclerotic plaques were found in 59 patients (27.8%), predominantly in older individuals (66.0 [59.0; 73.0] versus 55.0 years [42.0; 61.0], p<0.001) and in men (51.6 versus 23.8% in women, p=0.001). Atherosclerotic plaques were detected in 46.3% of smokers versus 23.4% of non-smokers (p=0.003). Atherosclerotic plaques were more frequently detected in patients with type 2 diabetes mellitus (58.3 versus 26.0%, p=0.036), arterial hypertension (41.7 versus 5.0%, p<0.001), angina pectoris (73.1 versus 21.5%, p<0.001), past history of acute cerebrovascular event (83.3 versus 25.9%, p=0.008), and the presence of post-infarction cardiosclerosis (100.0 versus 26.6%, p=0.03). No atherosclerotic plaques were found in 48 non-climacteric women. Except for the level of rheumatoid factor, all parameters of rheumatoid arthritis activity did not demonstrate statistically significant differences between groups with and without atherosclerotic plaques. The intima-media thickness mainly correlated with age (rs=0.633, p<0.001) and was not associated with rheumatoid arthritis activity. After the use of age- and sex-specific ultrasound criteria, the proportion of patients with intima-media thickening increased from 34.9 to 58.0% (p<0.001). Prevalence rates of most cardiovascular risk factors were associated with age and gender.Conclusion. The present study identified the differences between the incidence rates of traditional risk factors in patients with rheumatoid arthritis compared with the corresponding values in world studies and generated comparable results with REMARKA study confirming a significance of studying this question in the context of the Russian population. The results, obtained in this study, improve understanding of the structure of risk factors in patients with rheumatoid arthritis and may provide the basis for the algorithm of curation of patient with high cardiovascular risk.
