OBJECTIVE
To clarify the relationship between dietary habit and disease activity of rheumatoid arthritis (RA).
METHODS
This study enrolled RA patients who met the ACR/EULAR 2010 classification criteria from Kyoto University Rheumatoid Arthritis Management Alliance (KURAMA) cohort in 2015. 22-item food frequency questionnaire (FFQ) was taken for the measurement of dietary habit in a single-institution cohort of RA (Kyoto University Rheumatoid Arthritis Management Alliance: KURAMA) in 2015. The disease activities of RA using the Disease Activity Score calculated based on the erythrocyte sedimentation rate (DAS28-ESR), Simplified Disease Activity Index (SDAI), Health Assessment Questionnaire (HAQ), and serum matrix metalloproteinase-3 (MMP-3) level, the use of disease-modifying anti-rheumatic drugs (DMARDs), disease duration, rheumatoid factor, anti-cyclic citrullinated antibody, and body mass index were also examined. All of them were combined and statistically analyzed.
RESULTS
441 RA patients (81% women; mean age 65 years; mean disease duration 15 years) were enrolled from the KURAMA cohort. Average Disease Activity Score-28 using the erythrocyte sedimentation rate (DAS28-ESR) was 2.7. Univariate analysis showed that intake frequency of vegetables had a statistically significant negative correlation with disease activity markers, such as DAS28-ESR (ρ = -0.11, p<0.01), Simplified Disease Activity Index (SDAI) (ρ = -0.16, p<0.001), matrix metalloproteinase-3 (MMP-3) (ρ = -0.21, p<0.0001), and Health Assessment Questionnaire (HAQ) (ρ = -0.13, p<0.01). Factor analysis with varimax rotation was done to simplify the relevance of disease activity to various food items. 22 foods were categorized into five dietary patterns: "seafoods", "vegetables/fruits", "meats/fried foods", "snacks", and "processed foods". The multivariate analysis adjusted for clinically significant confounders showed that "seafoods" had statistically significant negative correlations with DAS28-ESR (β = -0.15, p<0.01), SDAI (β = -0.18, p<0.001), MMP-3 (β = -0.15, p<0.01), and HAQ (β = -0.24, p<0.0001). "Vegetables/fruits" had statistically significant negative correlations with SDAI (β = -0.11 p<0.05), MMP-3 (β = -0.12, p<0.01), and HAQ (β = -0.11, p<0.05).
CONCLUSIONS
These results suggest that high intake frequency of vegetables/fruits and/or seafoods might correlate with low disease activity.
目的
阐明饮食习惯与类风湿关节炎（RA）疾病活动之间的关系。
方法
本研究纳入了 2015 年来自京都大学类风湿关节炎管理联盟（KURAMA）队列中符合 ACR/EULAR 2010 分类标准的 RA 患者。在 2015 年，对 RA 患者进行了单机构队列（京都大学类风湿关节炎管理联盟：KURAMA）的 22 项食物频率问卷（FFQ）测量饮食习惯。使用红细胞沉降率（DAS28-ESR）计算的疾病活动评分（DAS28-ESR）、简化疾病活动指数（SDAI）、健康评估问卷（HAQ）和血清基质金属蛋白酶-3（MMP-3）水平来评估 RA 的疾病活动，使用疾病修正抗风湿药物（DMARDs）、疾病持续时间、类风湿因子、抗环瓜氨酸抗体和体重指数也进行了检查。将所有这些因素结合起来进行了统计分析。
结果
从 KURAMA 队列中纳入了 441 例 RA 患者（81%为女性；平均年龄 65 岁；平均病程 15 年）。平均红细胞沉降率 DAS28（DAS28-ESR）为 2.7。单因素分析显示，蔬菜的摄入频率与疾病活动标志物如 DAS28-ESR（ρ=-0.11，p<0.01）、简化疾病活动指数（SDAI）（ρ=-0.16，p<0.001）、基质金属蛋白酶-3（MMP-3）（ρ=-0.21，p<0.0001）和健康评估问卷（HAQ）（ρ=-0.13，p<0.01）呈统计学显著负相关。使用方差极大旋转进行因子分析，以简化疾病活动与各种食物之间的相关性。22 种食物被分为五种饮食模式：“海鲜”、“蔬菜/水果”、“肉类/油炸食品”、“零食”和“加工食品”。经过多变量分析调整了临床显著混杂因素后，结果表明“海鲜”与 DAS28-ESR（β=-0.15，p<0.01）、SDAI（β=-0.18，p<0.001）、MMP-3（β=-0.15，p<0.01）和 HAQ（β=-0.24，p<0.0001）呈统计学显著负相关。“蔬菜/水果”与 SDAI（β=-0.11，p<0.05）、MMP-3（β=-0.12，p<0.01）和 HAQ（β=-0.11，p<0.05）呈统计学显著负相关。
结论
这些结果表明，蔬菜/水果和/或海鲜的高摄入频率可能与低疾病活动有关。
