New Onset Psoriatic Arthritis Reported in Psoriasis Patients Treated with Efalizumab
|
The T-cell inhibitor efalizumab (Raptiva) has demonstrated efficacy in the treatment of moderate to severe plaque psoriasis. However, it has not demonstrated efficacy for the treatment of psoriatic arthritis and, in one study, was associated with worsening of arthritis symptoms. Only a minority of individuals with psoriasis have a concomitant inflammatory arthritis, making therapy with efalizumab an option for the treatment of a large number of psoriasis patients who have no articular involvement.

Denosumab, an inhibitor of RANKL, suppresses erosions but has no effect on articular signs and symptoms in rheumatoid arthritis
|
Bone erosions in response to inflammation in RA are driven by osteoclasts which are in turn activated by RANKL (Receptor Activator for Nuclear Factor κ B Ligand) binding to its receptor RANK. Inhibition of RANKL has the potential to retard bone erosions in RA patients, thereby limiting progressive joint damage and destruction.

Barriers to Urate Lowering Therapy Explored
|
Urate lowering therapy can be very effective for reducing flares of gout, thereby preventing ongoing joint damage and deformity. Despite this efficacy, most gout patients are undertreated, leading to undue painful flares and joint damage. Non-adherence to therapy is a strong contributor to undertreatment.

Golimumab Shows Promise for the Treatment of Rheumatoid Arthritis
|
There are currently three TNF agents on the market for RA; among these, infliximab is a chimeric monoclonal antibody against TNF-α administered as an infusion. Golimumab is similar to infliximab, except that it has been engineered to be fully human and is given as a subcutaneous injection.

Does Postmenopausal Hormone Replacement Affect Rheumatoid Arthritis Outcomes?
|
Estrogens are known to modify immunologic responses and the modulation of rheumatoid arthritis (RA) disease activity during pregnancy is well documented. However, whether physiologic replacement of estrogen and other hormones after menopause adversely affects RA outcomes is controversial. Here, Wallitt et al (Arthritis Care & Research 2008; 59: 302) explore whether postmenopausal hormone replacement therapy (HRT) increases the incidence or severity of RA in women enrolled in the Women Health Initiative (WHI) trials.

Do TNF Inhibitors Increase the Risk of Heart Failure in Rheumatoid Arthritis?
|
The observation that TNF-α is elevated in individuals with advanced heart failure (HF) prompted several high-profile clinical trials investigating whether TNF inhibitors could be used to treat HF. The failure of these trials and reports of RA patients treated with TNF inhibitors developing new-onset or worsening HF has raised questions as to whether TNF inhibition is beneficial or detrimental to the myocardium.

Is Glucosamine Sulfate an Effective Treatment for Osteoarthritis of the Hip?
|
Large scale, independent studies of glucosamine and/or chondroitin have not shown a definitive benefit for the treatment of painful knee osteoarthritis (OA) and the effect of retarding knee OA progression remains controversial.

European Admixture Associated with Genetic Risk for Rheumatoid Arthritis in African-Americans
|
Susceptibility to rheumatoid arthritis (RA) is complex; although a number of genetic susceptibility loci have been identified that appear to confer increased risk. Among these, genes encoding sequence variants in the major histocompatibility complex (MHC) class II molecule, known as the “shared epitope� (SE), have been known for decades and have the strongest link to RA susceptibility.
