[Treatment of rheumatoid polyarthritis with methotrexate].
This retrospective study involved 60 patients (7 men, 53 women) with rheumatoid arthritis (RA) and given methotrexate between 1985 and 1990. The mean time that RA had been present was 12 years and more than half of the patients had received more than 3 types of general treatment in the past. The mean total duration of MTX was 17.3 months, with a total dose of 790 mg. The efficacy of MTX was confirmed by a significant improvement in clinical and laboratory parameters. Treatment was withdrawn permanently in 21 cases (35% of patients). Adverse reactions, responsible for two thirds of treatment withdrawals (14/21) occurred in most instances during the first year of treatment. Hepatic toxicity was commonest. Two cases of aplasia were reported as well as 3 cases of pneumonitis, one fatal. These involved two cases of secondary infection and one of pneumonitis directly imputable to MTX. Withdrawals for inefficacy were rare, occurring in less than 10 p. cent of patients. Treatment continuation rates were 77 p. cent at 1 year, 66 p. cent at 18 months, 55 p. cent at 2 years, 42 p. cent at 3 years and 32 p. cent at 4 years. MTX is effective treatment for RA but is not free of adverse reactions, sometimes potentially fatal. Prolonged monitoring is necessary because of the sometimes delayed onset of adverse reactions.
