OBJECTIVE: The early diagnosis of rheumatoid arthritis (RA) is desirable to install treatment to prevent disease progression and joint destruction. Autoantibodies and immunological markers pre-date the onset of symptoms by years albeit not all patients will present these factors, even at disease onset. Additional biomarkers would be of high value to improve early diagnosis and understanding of the process, leading to disease development. METHODS: Plasma samples donated before the onset of RA were identified in the Biobank of Northern Sweden, a collection within national health survey programs...

Connective tissue diseases including systemic lupus erythematosus (SLE), rheumatoid arthritis, and scleroderma, have a strong predilection for women and are associated with a marked increase in the prevalence of hypertension. The mechanisms leading to the increased risk of hypertension in these patients remain unclear; however, they are likely related to immune mediated changes in cardiovascular and renal function. Over the past several years, we have elucidated a number of factors that contribute to the development of hypertension during SLE using a widely established experimental model of SLE, the female NZBWF1 mouse...

Rheumatoid arthritis (RA) is an autoimmune, inflammatory joint disease whose exact cause is still not completely known. Reactive oxygen species (ROS) are believed to be involved in the pathogenesis of RA. ROS are produced mostly by the phagocytic cells during oxidative burst and oxidative phosphorylation. Lipids, proteins and nucleic acids get damaged by the overproduction of ROS. Damaging effects of ROS are taken care by the enzymatic and non-enzymatic defence system of the body. Overproduction or inadequate elimination of reactive species leading to oxidative stress has been positively correlated with the disease severity in RA patients...

Non-steroidal anti-inflammatory drugs (NSAIDs) are a group of drugs which are used for a wide variety of diseases including pain and inflammatory conditions such as osteoarthritis, rheumatoid arthritis, musculoskeletal disorders, and other comorbid complications. However, this group of drugs have undesirable effects such as peptic ulcer, bleeding and renal failure. Some of these side effects are associated with or caused by generation of oxidative stress. Following the withdrawal of a cyclo-oxygenase-2 (COX-2) inhibitor drug, rofecoxib (VIOXX®) due to cardiovascular complications, scientists suggested that natural COX-2 inhibitors might provide valuable alternatives to COX inhibitors...

Resveratrol is a polyphenol derivatives which exhibits a pro-apoptotic effect in a variety of human cancers by triggering mitochondria apoptosis pathway and autophagy. However, there are scarcely reports on its apoptosis-promoting effect in abnormal proliferation fibroblast-like synoviocytes (FLSs). In this study, we investigated the underlying mechanism and apoptosis-inducing effects of resveratrol on the abnormal proliferation of FLSs in adjuvant-arthritis (AA) rats. Since using resveratrol for 12 days resulted in a significant decreasing the swelling degree of the paw, reducing malondialdehyde (MDA) content and enhancing superoxide dismutase (SOD) activity, antioxidant capacity, glutathione peroxidase and glutathione reductase ratio in AA rats...

Advanced oxidation production products (AOPPs) have been confirmed to accumulate in patients with rheumatoid arthritis (RA). Previous study demonstrated that AOPPs could accelerate cartilage destruction in rabbit arthritis model. However, the effect of AOPP stimulation on apoptosis of human chondrocyte and the underlying mechanisms remains unclear. This study demonstrated that exposure of chondrocyte to AOPPs resulted in cell apoptosis. AOPP stimulation triggered reactive oxygen species (ROS) production, which induced mitochondrial dysfunction and endoplasmic reticulum stress (ER stress) resulted in caspase activation...

Oxidised lipids, covering enzymatic and auto-oxidation-synthesised mediators, are important signalling metabolites in inflammation while also providing a readout for oxidative stress, both of which are prominent physiological processes in a plethora of diseases. Excretion of these metabolites via urine is enhanced through the phase-II conjugation with glucuronic acid, resulting in increased hydrophilicity of these lipid mediators. Here, we developed a bovine liver-β-glucuronidase hydrolysing sample preparation method, using liquid chromatography coupled to tandem mass spectrometry to analyse the total urinary oxidised lipid profile including the prostaglandins, isoprostanes, dihydroxy-fatty acids, hydroxy-fatty acids and the nitro-fatty acids...

Reactive oxygen species (ROS) and reactive nitrogen species (RNS) have distinct contribution to the destructive, proliferative synovitis of rheumatoid arthritis (RA) and play a prominent role in cell-signaling events. However, few studies had clarified the role of individual ROS and RNS in the etiopathogenesis of RA. To date, most of the studies were concerned with the measurement of the total oxidative and nitrative stress levels in RA. The aim of this study was to monitor the levels of individual ROS and RNS to emphasize the role that each plays in the pathogenesis of RA and their usefulness as possible biomarkers for the disease activity...
