Moreover, one of the major side effects of methotrexate (MTX) is gastrointestinal disorders, which are said to affect medication adherence.

A total of 558 RA patients participated. On the day of the GerdQ questionnaire, data on age, gender, disease duration, RA disease activity, lab results, and lifestyle factors such as smoking history and alcohol consumption were recorded.

After matching, higher GerdQ scores were correlated with increased tender joint counts 28 (TJC28) and worse visual analog scale (VAS) scores. Oral MTX usage was similar, but the dosage was significantly lower in the group with higher GerdQ scores (51.4% vs. 50.8% and 7.7 ± 2.4 mg/wks vs. 6.5 ± 2.6 mg/wks, p < 0.05*).</p><p><strong>Conclusions: </strong>GE symptoms significantly impact MTX treatment and patient-reported outcomes such as TJC28 and VAS in RA disease activity, highlighting their importance in RA treatment strategies.
