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.

    ABSTRACT: Destabilization of one predator–one prey systems with an increase in nutrient input has been viewed as a paradox. We report that enrichment can damp population cycles by a food-web structure that balances inflexible and flexible interaction links (i.e. specialist and generalist predators). We modeled six predator–prey systems involving three or four species in which the predators practice optimal foraging based on prey profitability determined by handling time. In all models, the balance of interaction links simultaneously decreased the amplitude of population oscillations and increased the minimum density with increasing enrichment, leading to a potential theoretical resolution of the paradox of enrichment in non-equilibrium dynamics. The stabilization mechanism was common to all of the models. Important previous studies on the stability of food webs have also demonstrated that a balance of interaction strengths stabilizes systems, suggesting a general rule of ecosystem stability.

    ABSTRACT: Infliximab is a chimeric mouse/human monoclonal anti-body against tumor necrosis factor-alpha (TNF-α) that is used worldwide to treat rheumatic disease. However, the reactivation of tuberculosis, including extrapulmonary me-nifestation, is a severe side effect of anti-TNF-α treat-ment. Mycobacterium tubercluosis causes two forms of joint involvement, TB arthritis and Poncet's disease. Poncet's disease is a rare aseptic form of arthritis, known as re-active arthritis in tuberculosis. We encountered a case of tuberculous peritonitis with Poncet's disease in a 38-year-old man with a history of ankylosing spondylitis that was treated with infliximab. We report this case with a review of the literature.

    ABSTRACT: Tuberculosis infection (TB) is one of the most important problems for the rheumatoid arthritis (RA) patients treated with anti-TNF agents. Pulmonary tuberculosis is the most common clinic form of the TB in these patients. However, tuberculosis arthritis is very rare. We present here a 72-year-old Caucasian woman with seropositive RA, treated with etanercept/adalimumab for the last 2 years, who presented with resistant knee pain and joint effusion. We believe that this treatment caused the tuberculosis in this patient, which is the most worried complication. Interestingly, tuberculosis was in the knee joint at this time.
