BACKGROUND: Patients with calcium pyrophosphate deposition disease sometimes require a continuous therapy. Nonsteroidal anti-inflammatory drugs, colchicine, and glucocorticoids are commonly used with good results, but occasionally, these are ineffective, contraindicated, or not tolerated. We present our experience with methotrexate (MTX) in refractory CPP arthritis.
METHODS: An observational study to describe and evaluate the use of MTX in refractory calcium pyrophosphate deposition disease was undertaken. Ten patients were included. Treatment response was evaluated by the physician (excellent, good, medium, poor, or absent response) and the patient as measured on a 10-cm visual analog scale (0 = no effect; 10 = complete resolution of symptoms). Adverse effects were recorded on all patients.
RESULTS: Five patients presented a persistent polyarthritis, 3 presented a persistent oligoarthritis, and 2 presented a very frequently recurring monoarthritis. Median MTX evaluation by patients on visual analog scale was 7.4, and physicians considered excellent (n = 2), good (n = 5), or medium (n = 3). The safety profile was generally good, but MTX was discontinued in 2 patients because of adverse effects (transient bone marrow aplasia and elevation of liver enzymes).
CONCLUSIONS: Methotrexate could be an effective and safe option for patients with refractory CPP arthritis, but additional studies are necessary to determine to what extent and for which patients MTX is effective.
