High frequency of methotrexate intolerance in longstanding rheumatoid arthritis: using the methotrexate intolerance severity score (MISS)

Abstract Background Methotrexate (MTX) intolerance is frequent, and its early identification may impact treatment, leading to timely changes in medication that may promote patient compliance and better control of rheumatoid arthritis (RA). The objective of this study was to identify the frequency of...

description Abstract Background Methotrexate (MTX) intolerance is frequent, and its early identification may impact treatment, leading to timely changes in medication that may promote patient compliance and better control of rheumatoid arthritis (RA). The objective of this study was to identify the frequency of, and risk factors for, MTX intolerance using the Brazilian Portuguese version of the Methotrexate Intolerance Severity Score (MISS) questionnaire in patients with RA. Methods This cross-sectional study was performed between April 2018 and April 2019 and enrolled patients with RA in regular use of oral or subcutaneous MTX for at least 3 months. Patients were invited to answer the Brazilian Portuguese version of the MISS questionnaire, and MTX intolerance was defined by a score ≥ 6 points. Age, sex, disease duration, time of MTX use, dose, route of administration, concomitant medications, comorbidities, smoking, and Disease Activity Score for 28joint (DAS28) data were collected from institutional medical records. Results Among 120 patients, 103 (85.8%) were female, the mean age was 61 (±12.5) years, the mean duration of disease was 16 (±10.3) years, and the average duration of MTX use was 7 (±5.5) years. The frequency of MTX intolerance was 21.6%. The most frequent symptoms reported after the use of MTX were nausea (92.3%), abdominal pain (46.1%), and vomiting (30.7%). Behavioral symptoms occurred in 96.1% of patients with MTX intolerance, the most frequent being restlessness and irritability. Patients who used corticosteroids were more likely to develop MTX intolerance than those not using corticosteroids (odds ratio = 2.73; 95% confidence interval, 1.06 to 7.06; p = 0.038). Conversely, increasing age showed marginally significant association with decreased risk of MTX intolerance (p = 0.059). Conclusions The use of the MISS questionnaire disclosed high frequencies of anticipatory, associative, and behavioral symptoms in MTX-intolerant patients, and the use of corticosteroid increases the risk of MTX intolerance. We suggest that the MISS questionnaire be used routinely in clinical practice.
