An 80-year-old woman presented with rapid, progressive and multiple cavitary lesions in both lungs. Rheumatoid arthritis had been diagnosed and been treated with prednisolone (5 mg/day) and bucillamine since 1996. Due to worsening of arthralgia, methotrexate (6 mg/week) and leflunomide (10 mg/day)
Leflunomide is a disease-modifying antirheumatic drug with antiinflammatory and immunosuppressive activity used for the treatment of psoriatic and rheumatoid arthritis. It undergoes rapid metabolization to teriflunomide, a metabolite that is responsible for the biological activity of leflunomide.
The anti-inflammatory effects of methotrexate (MTX), an anti-rheumatic drug for treating rheumatoid arthritis, on acute inflammation were studied by using Arthus reactions induced in the pleural cavity and dorsal skin of rats. The effects were compared with those of dexamethasone (DEX), a synthetic
A reversed passive Arthus reaction was elicited in the rat pleural cavity. The kinetics of this inflammatory response indicate that exudate volume (cells and fluid) reaches a maximum level approximately 2 to 4 hr postantibody challenge. The neutrophil is the major cellular constituent of the pleural
Free radicals are involved in diverse disorders such as tumoral, central nervous system alterations, immunological and inflammatory pathologies. Peroxidase is an oral enzyme involved in the defense of the oral cavity. Ilex species such as Ilex paraguariensis St. Hil. and the commercial product made
Mononuclear cell accumulation is of major importance in maintaining chronic inflammatory conditions. In an effort to model this phenomenon, 0.3 ml of a 1% carrageenan solution was injected into the pleural cavity of rats; at various times thereafter peripheral blood and pleural exudate samples were
We assessed the effect of a novel and selective phosphodiesterase 4 (PDE4) inhibitor, ciclamilast, on chronic inflammation in adjuvant-induced arthritis (AIA), a rat model of rheumatoid arthritis (RA), and acute inflammation in the rat and mouse model of carrageenan-induced paw edema and
At present, the early phenomenon of inflammatory angiogenesis is rarely studied in Rheumatoid arthritis (RA). Previous research found that PEG-HM-3, an integrin inhibitor, possessed anti-angiogenesis and anti-rheumatic activity. In this study, the advantages of inhibiting angiogenesis and immune
Previous animal studies have established that the intra-articular injection of holmium-166-chitosan complex (DW-166HC) causes effective necrosis of the inflamed synovium with litle leakage of radioactivity from the injected joint. Based on these findings, we conducted a phase I/IIa study to examine
The effects of a nonsteroidal anti-inflammatory agent, indomethacin, a steroidal anti-inflammatory drug, dexamethasone and an antirheumatic agent, levamisole, on rat polymorphonuclear leukocyte (PMN) adherence and migration were examined. Adherence was evaluated using nylon fiber columns and
In 75 patients with visceral rheumatism prior to and following antirheumatic treatment the authors studied the REG in a frontomastoidal and occipito-mastoidal leading as well as the REG of the brachial muscles. In one group of patients there were REG signs of a significantly increased tone of the
The diagnosis of reactive arthritis (ReA) is easy in typical cases with a history of an infection within 3 weeks in combination with an asymmetric mono or oligoarthritis with or without extra-articular manifestations. Subclinical microbial infections, a possible co-existing inflammatory bowel
BACKGROUND
With socio-economic changes, dentists and maxillofacial surgeons are more and more faced with medically compromised patients. Especially, the admission of antirheumatic drugs has increased remarkably. So dentists and maxillofacial surgeons should be aware of related adverse reactions that
Parasitic rheumatism is a rare condition characterized by inflammatory joint manifestations due to a parasitic infestation without parasites into joint cavity, (but, with circulating immune complexes, in serum, and synovial fluid; and with immunoglobulins and complement deposits in synovium in some
OBJECTIVE
To assess the role of diagnostic imaging techniques in the identification and follow-up of the anatomical damage induced by the chronic inflammatory process of rheumatoid arthritis (RA) not only to study the natural history of the disease but also and especially to assess the long-term
