TCZ resulted in a decrease of HDL-associated serum amyloid A, phospholipase A2, lipoprotein A, fibrinogen, D-dimer and elevation of paraoxonase while ApoB/ApoA1 ratio remained stable. Risk Assessment, Cardiovascular Outcomes, Pathogenesis, Treatment, Evaluation Introduction Rheumatoid Arthritis (RA), a chronic systemic inflammatory disease which affects approximately 1% of the population, is classically characterized by inflammation and synovitis that leads to cartilage damage Picropodophyllin with joint space narrowing and juxta-articular bone Picropodophyllin erosions. CVD risk is usually increased among RA patients as exhibited by numerous epidemiological studies, as the presence of traditional Cardio Vascular (CV) risk factors do not explain the higher rate of CV events seen in this populace. The inflammatory milieu of RA, marked by elevations of serum inflammatory mediators and endothelial dysfunction, creates an opportune climate for the development of atherosclerosis and cardio myocyte dysfunction. Accordingly, CVD in RA is usually associated with active RA disease as measured by joint swelling, extra-articular disease, and elevated serum inflammatory markers. Clinically, RA patients with CVD present with an increased rate of silent cardiac disease, atypical symptoms and diastolic heart failure. Predicting CVD and evaluating the risk have proven to be hard in RA, in part due to the paucity of studies and difficulties with risk calculator models. Imaging techniques and special functional tests may provide more reliable tools to assess risk and progression of CVD in this individual populace. Optimizing prevention and management in RA includes a combination approach that addresses traditional risk factors and inflammation. Epidemiology The Picropodophyllin acknowledgement that RA carries a heightened CVD morbidity and mortality derived from a number of reviews and meta-analysis. In a review that included 91,618 patients, CVD accounted for 39.6% of all deaths . One meta-analysis comprising 111,758 patients found a 50% increased risk of CVD death, with Ischemic Heart Disease (IHD) and Cerebral Vascular Accidents (CVA) accounting for 59% and 52% increased risks, respectively . Another meta-analysis of 14 observational studies concluded a 48% increased risk of incident CVD in patients with RA, with the risk of Myocardial Infarction (MI) and CVA being increased by 68% and 41%, respectively, with a single study identifying the risk of Congestive Heart Failure (CHF) increased by 87% . These statistics are supported by a recent prospective population-based cohort study of CVD end-points showing that RA patients had higher rates, via adjusted incidence ratio (IRR) of MI (IRR: 1.43), unheralded coronary death (1.60), heart failure (1.61), cardiac arrest (2.26), peripheral arterial disease (1.36) and reduce rates of stable angina (hazard ratio: 0.83) . Increased incidence of CV events in RA patients have been linked to that in diabetics, with a two-fold increase compared to the general populace . Most recently, a large population-based study matched RA patients 15 years of age to individuals without RA. The mortality rate for RA patients was 232-compared to184 in the non-RA populace (14% versus 9%). Overall, RA patients experienced increased all-cause mortality, but age specific mortality ratios suggested extra mortality among patients more youthful than 45 years due to respiratory and circulatory diseases . The majority of population-based studies are derived primarily from European and North American cohorts. A recent cross-sectional study of Chinese patients showed an approximately two-fold increased risk of CVD, IHD and CHF in RA patients compared to age and sex-matched controls . One South African study looked at CVD in RA patients belonging to an African Black populace cohort. Their review argues that CVD in RA occurring in developed populace cohorts cannot be extrapolated to developing countries populace as further research is needed to ascertain the true disease prevalence given Mouse monoclonal to CD20 the degree of heterogeneity in ethnicity and geographic locations . Pathophysiology The pathophysiology of CVD in RA entails immune dysregulation and chronic inflammation which results from the conversation of genetic and environmental factors . Inflammation favors atherosclerotic CVD, with inflammatory markers like C Reactive Protein (CRP) considered impartial predictors for coronary heart disease in the general populace [10, 11]. Evidence supports that inflammation is the major driver of excess CVD in RA [12, 13]. Systemic Inflammation and Endothelial Dysfunction Elevated levels of cytokines such as tumor necrosis factor- (TNF-), interleukin-17 (IL-17), interleukin-6 (IL-6), and interleukin-1 (IL-1) are found in both RA and CVD, with higher levels being present in RA [10, 14C16]. These cytokines have been implicated in endothelial cell activation, a crucial step for pannus formation in the synovial tissue and in the pathogenesis of atherosclerotic CVD [10, 17, 18].
