Abstract
Objective: To explore the menopause status of patients with rheumatoid arthritis (RA) and clinical characteristics of perimenopausal RA patients. Methods: A cross-sectional study. Female RA patients were recruited retrospectively in the Sun Yat-Sen Memorial Hospital from August 2015 to August 2023. Clinical data were collected, including onset age, disease duration, RA disease activity indicators, functional assessment, and radiographic scores. According to menopausal status, the patients were categorized as pre-menopausal, perimenopausal and post-menopausal groups to explore their menopausal and clinical characteristics. Results: A total of 1 151 female patients were enrolled, with a mean age of (50.2±13.0) years. At enrollment, there were 470 (40.8%), 140 (12.2%) and 541 (47.0%) patients in pre-menopause, perimenopause and post-menopause status, respectively. The mean age of menopause was (49.0±4.2) years. Compared with pre-menopausal group, perimenopausal RA patients had higher disease activity indicators [clinical disease activity index (CDAI) 17 (6, 26) vs 10 (3, 19) ], higher levels of inflammation [erythrocyte sedimentation rate (ESR) 35 (21, 65) vs 26 (14, 44) mm/1h, C-reactive protein (CRP) 6.2 (3.2, 16.8) vs 3.3 (3.2, 13.6) mg/L], and a higher proportion of functional limitation [25.0%(35/140) vs 10.4%(49/470)] (all P<0.016 7); while there was no significant differences in disease activity[M(Q1, Q3)] [CDAI 17 (6, 26) vs 14 (6, 25)], levels of inflammation [ESR 35(21, 65) vs 42 (23, 72) mm/1h, CRP 6.2 (3.2, 16.8) vs 6.2 (3.3, 23.9) mg/L] and functional limitation [25.0%(35/140) vs 28.8%(156/541)] when compared with those in post-menopausal group (all P>0.016 7). In RA patients during the perimenopausal period, 49 cases (35.0%) developed RA during this period. Compared with patients with RA onset during reproductive age, patients with RA onset during the perimenopausal period had higher numbers of 28-joint tender joints [7 (2, 10) vs 4 (0, 8)], higher CDAI [20 (12, 29) vs 14 (4, 24)], and higher ESR [45 (25, 72) vs 32 (18, 56) mm/1h] (all P<0.05). Conclusion: Perimenopausal patients with RA have severe disease activity and functional limitation.
