Objectives To evaluate comparative efficacy of injection and tablet methotrexate forms in rheumatoid arthritis treatment.
Methods 23 patients were included in study group (19 women, 4 men) with moderate (47.8%) and high activity (52.2%), receiving methotrexate subcutaneously in a dose of 10 -15 mg (average dose - 11 1±5,21) 1 time per week: 11 patients were switched from methotrexate tablet form, 2 patients received leflunomide previously, 10 patients received methotrexate initially. Comparison group - 20 patients (17 women, 3 men) taking methotrexate (10 -15 mg/week, the average dose 11,6±4,89) in tablets. The groups were comparable on key parameters. Effectiveness evaluation (ACR and EULAR criteria) and tolerability of treatment was carried out every 4 weeks for 6 months.
Results Significant clinical and laboratory improvement (ACR 20) was achieved in 23 patients (main group) and in 14 patients - the control group. The appearance of the first effect (ACR 20) of methotrexate subcutaneously was observed after 2 weeks of treatment in 8 (34.8%), one month therapy - 17 (73.9%) patients, in the control group at 2 weeks - in 1 (5%), after 1 month at 7 (5%) patients respectively. After 6 months of methotrexate subcutaneously treatment decrease in activity (DDAS28ESR 2,3±0,9, initial DAS28ESR 5,3±2,9) corresponds to good effect, and treatment was significantly (p<0.05) better compared to the group receiving methotrexate in tablet form (DDAS28ESR 1,3±1,0, initial DAS28ESR 5,2±2,6). Adverse events occurred in 5 (21.7%) patients of the main group (alopecia, itching at the injection site, increased transaminases less than 1.5 normal) did not require discontinuation of the drug, in the control group - in 11 (55%) patients: dyspepsia, alopecia, increased transaminases, 2 (10%) patients refused from therapy
Conclusions Subcutaneous administration of methotrexate in RA patients demonstrated more rapid and pronounced effect, better tolerability compared with taking the drug inside.
