Association between disease activity and quality of life among patients with rheumatoid arthritis

Abstract The aim of this study is the association between the scores of disease activity, functional capacity and quality of life among patients diagnosed with rheumatoid arthritis, under clinical treatment at the Regional University Hospital of Campos Gerais - Wallace Thadeu de Mello and Silva. The sample was composed by volunteer patients, who freely underwent 3 research questionnaires. With the results of the survey, the disease activity score was correlated to the functional capacity and the quality-of-life scores. A mean of 3.87 and 1.2 was observed for the disease activity and the functional capacity scores, respectively, yet not achieving a correlation between those two variables. A strong correlation between the disease activity and the "functional capacity", "general health status" and "mental health" domains was found. The lowest average observed corresponded to "physical limitation", from the quality-of-life questionnaire. There was no statistically significant correlation between disease activity and functional capacity, although disease activity seems to affect the mental health, general health status and functional capacity of patients.

Myeloperoxidase as an important predictor of cardiovascular risk in individuals with rheumatoid arthritis.

BACKGROUND: Rheumatoid arthritis is an inflammatory disease with joint manifestations. In the presence of extra-articular manifestations, the morbidity and severity of the disease increase. Glucocorticoid is used as a treatment and may result in side effects related to cardiovascular risk. METHODS: This was a cross-sectional study including 59 volunteers with rheumatoid arthritis receiving treatment at a hospital of Campos Gerais that aimed to establish the relation between cardiovascular risk, glucocorticoid treatment and myeloperoxidase in these patients. Subjects were divided into two groups: using (n = 39) and without glucocorticoids (n = 20). They underwent clinical evaluation, physical examination and blood samples were taken. Statistical analysis was performed using Student's t test and Mann-Whitney test. Logistic regression was performed to assess the cardiovascular risk. The significance level was 5% (α = 0.05). Calculations were performed using the Statistical Package for the Social Science version 21.0. RESULTS: There has been a significant difference between groups in blood glucose values (p = 0.012), which can be explained by the different percentage of diabetic patients in the groups. When assessing cardiovascular risk using the predictors of glucocorticoid dose, time of glucocorticoid use, myeloperoxidase, and C-reactive protein together, these were responsible for significantly predicting this risk (p = 0.015). CONCLUSION: A significant relation between the predictor myeloperoxidase alone was also demonstrated (p = 0.037), it may be an important predictor of cardiovascular risk among individuals with rheumatoid arthritis.

Relationship between corticotherapy and increased cardiac risk in patients with rheumatoid arthritis

Rheumatoid arthritis is an autoimmune inflammatory joint disease with global prevalence of 0.4% to 1.0%. Extra-articular manifestations increase its morbidity and severity, and cardiovascular diseases present the greatest risk. Therapeutic approaches have been used to treat rheumatoid arthritis, often involving the use of multiple classes of drugs with different mechanisms and forms of action. Corticosteroid therapy is widely used in this therapeutic combination; however, its use has been widely questioned because of its high toxicity and some negative effects, including the possibility of increased cardiovascular risk, depending on the dosage. Some studies have provided important insights into how glucocorticoids have an impact on cardiac complications in patients with rheumatoid arthritis. Most of these studies have concluded that exposure to these drugs at high or cumulative doses is associated with increased risk of death, as well as possibly being associated with the presence of a positive rheumatoid factor.
