Psoriatic arthritis (PsA) is a common form of inflammatory arthritis that affects people with psoriasis. Both psoriasis and PsA are associated with metabolic diseases including obesity, hypertension, hyperlipidaemia, diabetes mellitus, fatty liver disease, and cardiovascular disease including myocardial infarction. Dietary interventions for psoriatic disease have been of great interest, particularly among patients with PsA.
Herein, we review the evidence for dietary intervention in psoriatic arthritis. To date, weight loss among patients who are obese has the greatest evidence for benefit. We also examine the evidence for fasting, nutrient supplementation, and specific diets as adjunct therapeutic strategies.
While the data do not clearly support a single dietary intervention across the disease, weight loss among those who are obese results in improved PsA disease activity and physical function. Additional studies are needed to better understand the impact of diet on psoriatic arthritis.
银屑病关节炎（PsA）是一种常见的炎症性关节炎，影响银屑病患者。银屑病和 PsA 均与代谢疾病相关，包括肥胖、高血压、高脂血症、糖尿病、脂肪肝和心血管疾病，包括心肌梗死。针对银屑病的饮食干预措施一直备受关注，尤其是在患有 PsA 的患者中。
本文综述了饮食干预在银屑病关节炎中的作用。迄今为止，肥胖患者的体重减轻具有最大的获益证据。我们还检查了禁食、营养补充和特定饮食作为辅助治疗策略的证据。
尽管数据并未明确支持针对该疾病的单一饮食干预，但肥胖患者的体重减轻可改善 PsA 疾病活动度和身体功能。需要进一步研究以更好地了解饮食对银屑病关节炎的影响。
