Comparison of lipid and lipid-associated cardiovascular risk marker changes after treatment with tocilizumab or adalimumab in patients with rheumatoid arthritis

Ann Rheum Dis. 2015;0:1-7. doi:10.1136/annrheumdis-2015-207872 [Epub ahead of print]

RA patients have increased risk of CVD compared with the general population that is not fully explained by traditional risk factors. This is a post-hoc analysis of data from a clinical trial that compared IL-6 and TNF-α signaling inhibition to compare changes in lipids and lipid-associated CV risk markers in 324 patients treated with TCZ IV q4w or ADA SC q2w for 24 weeks. HDL-SAA and sPLA2 IIA is also measured in an additional subpopulation of 87 and 97 TCZ and ADA patients, respectively.Greater...

Potential Mechanisms Leading to the Abnormal Lipid Profile in Patients With Rheumatoid Arthritis Versus Healthy Volunteers and Reversal by Tofacitinib

Arthritis Rheumatol. 2015;67(3):616-25.

Active RA is associated with changes in both high- and low-density lipoprotein cholesterol as well as changes in the level and function of several HDL-associated proteins, yet the pathways and mechanisms involved with systemic inflammation altered lipid metabolism have not been determined. In addition, treatments for active RA are known to modify lipid metabolism, such as increasing circulating cholesterol levels. In the clinical development programme, a proportion of tofacitinib-treated patien...

Cytokine networks—towards new therapies for rheumatoid arthritis

Nature Clinical Practice 2005; 1(1):31-9

This review describes cytokines and the cytokine network in chronic inflammatory diseases such as rheumatoid arthritis (RA). It also discusses how therapies that target cytokines may be feasible and efficacious treatments option for RA. Various targets are considered including blockade of tumour necrosis factor (TNF) and interleukin-1 (IL-1), as well as the targeting of cytokines that play a central role in immune regulation and tissue matrix destruction such as IL-6, IL-15, interferon-gamma (IF...

Cytokines in the pathogenesis of rheumatoid arthritis

Nature Reviews Immunology 2007; 7:429-42

The imbalance between the activity of pro- and anti-inflammatory cytokines favouring induction of autoimmunity, chronic inflammation and joint damage is well known, but how cytokines are organised within a hierarchical regulatory network and which cytokines are the best targets for clinical intervention is uncertain. This review therefore examines the effector function of cytokines in the immunological processes central to the pathogenesis of rheumatoid arthritis (RA). The paper aims to try and ...

The pathogenesis of rheumatoid arthritis

The New England Journal of Medicine 2011; 365:2205-19

This review article describes the pathogenic processes involved in rheumatoid arthritis (RA) and discusses the genetic factors and environmental triggers implicated in the disease. Data from twin studies are discussed along with candidate genes with single nucleotide polymorphisms (SNPs) that have been linked to RA. It is now thought a multistep progression to the development of RA occurs via environmental factors, epigenetic modification of susceptible genes that leads to altered post-transcrip...

Back to the future: oral targeted therapy for RA and other autoimmune diseases

Nature Reviews Rheumatology 2013; 9(3):173-82

This review paper considers how advances in understanding of the disease process underlying rheumatoid arthritis (RA) and the development of novel techniques have transformed the management of this progressively disabling condition. Physicians are no longer limited to prescribing symptomatic treatments such as non-steroidal anti-inflammatory drugs (NSAIDs) or choosing from a seemingly random array of drugs drawn from multiple disciplines, such as methotrexate and sulphasalazine, which are descri...

Open-label tofacitinib and double-blind atorvastatin in rheumatoid arthritis patients: a randomised study

Annals of Rheumatic Diseases 2013; doi:10.1136/annrheumdis-2012-202442

This randomised, placebo-controlled, multicentre phase 2 study evaluated the efficacy and safety of atorvastatin versus placebo in modifying lipids in 111 patients with active rheumatoid arthritis (RA) receiving tofacitinib. All patients took tofacitinib 10 mg twice daily for 12 weeks, and after the first 6 weeks patients were randomised 1:1 to receive either atorvastatin 10 mg once daily (n=50) or matched placebo (n=48) in a double-blind phase for a further 6 weeks. Tofacitinib-induced elevatio...
