Etanercept (Enbrel), a recombinant, dimeric, soluble tumour necrosis factor (TNF) receptor protein, is approved in various countries for the treatment of adult patients with ankylosing spondylitis or psoriatic arthritis. Monotherapy with subcutaneous etanercept 25mg twice weekly or 50mg once weekly was effective and generally well tolerated in patients with ankylosing spondylitis or psoriatic arthritis participating in several large, well designed clinical studies. Treatment with etanercept was more effective than placebo in reducing disease activity and improving health-related quality of life (HR-QOL) in both patient populations, and in delaying structural disease progression in patients with psoriatic arthritis. The beneficial response to etanercept achieved with shorter-term treatment was sustained in studies of up to 4 years' total duration. Randomised, well designed, head-to-head comparisons, including pharmacoeconomic analyses, with other anti-TNF biological modulators are required to accurately position etanercept and fully establish its cost effectiveness. In the meantime, etanercept is a valuable treatment option for patients with ankylosing spondylitis or psoriatic arthritis who are suitable candidates for therapy.

Psoriasis and psoriatic arthritis are debilitating inflammatory immunemediated diseases which are chronic in nature and often require lifelong attention. Traditional therapies used to combat these diseases lack sufficient long-term efficacy and are associated with a number of toxicities. Failing to adequately satisfy both patients and physicians, traditional therapies have proven insufficient and have left few options. Etanercept is a tumor necrosis factor (TNF) antagonist that reduces elevated TNF levels by competitively binding to both TNF-alpha and TNF-beta and inhibiting the proinflammatory cascade. Providing a valuable treatment option alone, etanercept can also be effectively administered in conjunction with traditional treatments. Etanercept is self administered by subcutaneous (SC) injection, making treatment less of a burden for patients by eliminating the need for frequent office visits and laboratory testing. Etanercept is approved in the US for the treatment of psoriasis, psoriatic arthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, and ankylosing spondylitis.

New pathogenetic insights have identified the key role of TNF-alpha in inflammatory rheumatic diseases and have revolutionized the therapy of spondyloarthritides. TNF-alpha-antagonists specifically inhibit the pro-inflammatory effects of TNF-alpha. Clinical studies with infliximab (Remicade), Etanercept (Enbrel) or Adalimumab (Humira) in ankylosing spondylitis or related diseases demonstrate superior efficacy to conventional drugs like non-steroidal antirheumatic drugs or traditional disease modifying antirheumatic drugs.

Etanercept is a tumor necrosis factor (TNF) blocking agent that has been shown to suppress ongoing experimental autoimmune myasthenia gravis (EAMG). This subcutaneously administered TNF blocking agent has also been shown to be safe and effective in several rheumatological diseases including rheumatoid arthritis, psoriasis, and ankylosing spondylitis. A prospective clinical pilot trial of etanercept in corticosteroid-dependent autoimmune myasthenia gravis (MG) patients supports further study into etanercept as a treatment for MG.

With the development of biologicals that specifically target tumor necrosis factor (TNF)alpha, our therapeutic approach to inflammatory diseases has dramatically changed. There are currently three anti-TNFalpha drugs available: etanercept, infliximab, and adalimumab. Etanercept is a recombinant fusion protein that can be used alone or in combination with other medications for conditions such as rheumatoid arthritis, juvenile rheumatoid arthritis, psoriatic arthritis, psoriasis, and ankylosing spondylitis. Infliximab, a chimeric humanized monoclonal antibody and adalimumab, a fully human monoclonal antibody are approved for the treatment of rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, and moderate to severe Crohn's disease. Infliximab is also approved for ulcerative colitis. Another anti-TNFalpha drug, certolizumab pegol, was declined approval as treatment option for active Crohn's disease due to a lack of sufficient efficacy. Phase III studies for the treatment of rheumatoid arthritis patients are still pending. It is the goal of this review article to summarize various therapeutic indications, underlying studies, safety, and use during pregnancy, as well as future directions for anti-TNF therapies.

Lymphoedema is a rare complication of psoriatic arthritis (PsA) and inflammatory joint disease, with no response noted to disease-modifying drugs. However, reports are emerging of a beneficial effect on lymphoedema in patients treated with tumor necrosis factor-alpha antagonists for PsA (Etanercept), rheumatoid arthritis (Etanercept) and ankylosing spondylitis (Infliximab). We describe a psoriatic arthritis patient whose lymphoedema greatly improved following commencement of adalimumab.

Etanercept is a soluble TNF receptor p75 fusion protein which is approved for subcutaneous use (50 mg weekly) in the treatment of patients with active rheumatoid arthritis (RA), juvenile RA, ankylosing spondylitis, and psoriatic arthritis. Etanercept binds to both TNFalpha and lymphotoxin and has quite a short mean half-life (70 hours). Numerous randomized clinical trials have demonstrated its efficacy to improve signs and symptoms in early and established RA and other inflammatory arthritis. Furthermore, etanercept has shown its ability to prevent radiographic progression and to improve health-related quality of life in patients with RA and psoriatic arthritis. A combination of etanercept plus methotrexate was more efficacious than etanercept monotherapy in RA patients but there is currently no evidence that such rheumatic combination is better than monotherapy in other disorders. Etanercept was generally well tolerated both in controlled trials with withdrawal rates being similar to the comparator groups and in large observational studies. Infections and injection-site reactions were the most frequently reported events. Serious infections were slightly increased but the occurrence of tuberculosis seemed less frequent than with anti-TNF monoclonal antibodies (infliximab and adalimumab). The benefit-risk ratio of etanercept appeared to be very positive, and this drug has now emerged as a major therapy in patients with active inflammatory arthritis. Furthermore, it is more frequently considered as an emerging and valuable option in patients with early disease.

Etanercept is singular among anti-tumor necrosis factor alpha (TNF-alpha) agents, for being a soluble antibody to both TNF and lymphtoxin-alpha. The long-term neutralization of two cachexins by etanercept would theoretically compromise early detection of malignancy. This case reports a patient who was treated by etanercept for 21 months due to ankylosing spondylitis. Metastatic malignancy of unknown origin developed, and silently led the patient to lethal hepatic rupture. With an example of a malignancy masking effect of soluble TNF receptor, this article questions a need for vigilant attention to de novo carcinoma during the therapy, and calls for refined strategies in modulating autoimmune diseases.

A female patient diagnosed with ankylosing spondylitis experienced a new onset acute iritis following the initiation of etanercept therapy and recurrent episodes of iritis continues during the treatment of etanercept. Etanercept-associated iritis was suspected. Anti-TNF therapies can alleviate uveitis in some studies, but in some other anecdotal reports etanercept is considered as the main cause of uveitis. A literature review is presented below. For clinicians, more attention must be paid to the potential association between uveitis or iritis and etanercept, and more careful surveillance of patients under etanercept treatment is necessary.

Etanercept is a tumor necrosis factor (TNF) inhibitor that has been used for the treatment of chronic inflammatory diseases including rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis. Because of its immunosuppressive activity, opportunistic infections have been noted in treated patients, most notably caused by Mycobacterium tuberculosis. Tuberculosis may present in an extrapulmonary or disseminated form. Since TNF-alpha inhibitors have been used in Korea, a few cases of TNF-alpha inhibitor associated tuberculosis have been described. However, tuberculous arthritis has not been previously reported. We describe a case of tuberculous arthritis in a 57-year-old woman with rheumatoid arthritis who was treated with etanercept.
