Depression and anxiety in an early rheumatoid arthritis inception cohort. associations with demographic, socioeconomic and disease features.

Objective: Depression and anxiety are not uncommon in Rheumatoid arthritis (RA). It is increasingly recognised that they are associated with high disease activity and worse disease outcomes. We aimed to examine the frequency of depression and anxiety in an early RA inception cohort and to explore associations with disease-related measures.

Inhibition of spleen tyrosine kinase in the treatment of rheumatoid arthritis.

The pathogenesis of RA is a complex and ever-changing landscape but amid the chaos of the disease process we have found effective treatment regimes. However, our current therapeutics, although targeting various components of both the innate and adaptive immune response, do not result in disease remission. Protein kinase inhibitors are attractive targets due to their ability to influence downstream signalling and their oral bioavailability.

Correlation of protease-activated receptor-2 expression and synovitis in rheumatoid and osteoarthritis.

Protease-activated receptor-2 (PAR-2) is known to be pro-inflammatory and increasing evidence points to an inflammatory component in osteoarthritis. This investigation examined the relationship between synovitis and PAR-2 expression, histological and immunohistochemical analysis being performed on synovial samples obtained from OA and RA patients, along with non-arthritic samples obtained by post mortem (PM). Samples were also analysed for PAR-4 expression, this receptor also having putative pro-inflammatory roles.
