[Treatment of rheumatoid arthritis of senile onset with methotrexate].

Elderly onset rheumatoid arthritis is a not rare disease with relevant social implications. The most important question is represented by the therapeutic choice, in relation to the typical problems of the elderly patients and to the frequent coexistence of other diseases. In this work, we evaluated the practicability and the efficacy of methotrexate therapy, at the dose of 5 mg/week, in 27 patients affected by elderly onset rheumatoid arthritis (mean age 73.76 +/- 3.39 years, range 70-83). Low dose prednisone was associated in order to control painful symptoms. Also sulindac was allowed. Frequent clinical and hematochemical controls were made in order to precociously evaluate the appearance of side effects. All the 27 patients completed the first year of treatment; during this period there was no drop out. Sixteen patients finished the second year too; during this year one patient dropped out because of significant hypertransaminasemia and another patient did not respect the follow-up. Clinical and hematochemical parameters were monitored. A significant improvement of all data was observed from the third month. A further amelioration was recorded in the following months. Our data suggest the efficacy and the safety of low dose methotrexate in the treatment of elderly onset rheumatoid arthritis. A careful evaluation of side effects is obviously necessary.
