OBJECTIVE
To determine why methotrexate (MTX) exacerbates rheumatoid nodules in some patients, despite the effective suppression of synovial inflammation.
METHODS
Phorbol myristate acetate (PMA)-induced differentiation of monocytes into multinucleated giant cells was used as an in vitro model to
Methotrexate is one of the most effective and widely used medications in the treatment of rheumatoid arthritis. One poorly understood side effect of methotrexate is increased rheumatoid nodule formation, a phenomenon which has been reported to occur in some patients despite suppression of synovial
The histochemical demonstration of acid phosphatase (ACP) and adenosine triphosphatase (ATP) has been combined with standard immunofluorescence techniques, using a panel of monoclonal and conventional antibodies, to examine lymphocyte and macrophage subsets and their microanatomical relationships
This is the first description of the development of rheumatoid nodules in 3 rheumatoid arthritis patients following leflunomide therapy. The nodules were localized at typical sites with preference of the extensor side of hands and elbow. One nodule examined histologically revealed the typical
A 51-year-old man had been treated at a nearby hospital since 1993 for rheumatoid arthritis. Right pectoralgia developed in December 1994, and the patient consulted a nearby hospital, which detected right pleural effusion retention was pointed out on chest x-ray films. The patient was referred and
OBJECTIVE
We sought further understanding of the association between methotrexate (MTX) therapy and accelerated development of subcutaneous rheumatoid nodules. The objective was to establish expression of genes involved in the transport, metabolism, and mechanism of action of MTX within nodule
A 58-year-old woman with chronic polyarthritis rapidly developed a large number of rheumatic nodules under treatment with methotrexate. A comparison with other cases reported to date showed that the sudden onset of such nodules after initiation of treatment, and their disappearance again after
The treatment of rheumatoid arthritis (RA) patients with methotrexate (MTX) is linked to the development or progression of rheumatoid nodules. The aim of this study was to determine whether folate and adenosine pathways-related single nucleotide polymorphisms might be predictive of increased nodule
