The primary objective was to investigate the prevalence of neuropathic-like pain in patients with psoriatic arthritis (PsA). Secondary outcomes were to investigate whether mood, fatigue, pain, disease severity and fibromyalgia are associated with neuropathic-like pain in PsA patients.
PsA patients were assessed for fatigue, mood, pain, disease activity and fibromyalgia using questionnaires. Neuropathic-like pain was assessed by PainDetect.
Sixty-four patients with PsA were recruited from the Rheumatology Outpatient Department. Of the 64 patients recruited, 26.6% had 'likely neuropathic pain' and 21.9% had 'possible neuropathic-like pain' according to the PainDetect questionnaire. Patients with 'likely neuropathic pain' had higher disease activity, health assessment questionnaire, patient global self-assessment score, tender and swollen joint counts, dactylitis, enthesitis, pain severity and interference with day-to-day activities, fatigue severity and impact, fibromyalgia, anxiety and depression than 'unlikely neuropathic pain' patients (p < 0.05). PainDetect score correlated with measures of disease activity, fatigue, depression, anxiety, Widespread Pain Index and Symptom Severity Scale (all p < 0.05). Most patients (71%) with neuropathic-like pain fulfilled American College of Rheumatology 2010 fibromyalgia criteria. Patients with 'possible neuropathic-like pain' had scores between patients with 'likely neuropathic pain' and 'unlikely neuropathic pain'.
Neuropathic-like pain as evidence of abnormal pain processing is common in patients with PsA. It is associated with higher disease activity and fibromyalgia. A significant proportion of patients had 'possible neuropathic-like' pain with intermediate disease and symptom score suggesting neuropathic-like pain as evidence of abnormal pain processing is a continuum rather than concurrent fibromyalgia. Key Points • Neuropathic pain is prevalent in psoriatic arthritis. • Higher levels of pain, disease activity, fatigue, depression, anxiety and comorbidities in Psoriatic arthritis. • Increased pain severity is associated with increased disease activity, fatigue, depression and anxiety.
主要目的是调查银屑病关节炎（PsA）患者中神经性疼痛的患病率。次要结局是调查情绪、疲劳、疼痛、疾病严重程度和纤维肌痛是否与 PsA 患者的神经性疼痛相关。
使用问卷评估 PsA 患者的疲劳、情绪、疼痛、疾病活动度和纤维肌痛。通过 PainDetect 评估神经性疼痛。
从风湿病门诊招募了 64 名 PsA 患者。根据 PainDetect 问卷，64 名入组患者中，26.6%有“可能的神经性疼痛”，21.9%有“可能的神经性样疼痛”。有“可能的神经性疼痛”的患者疾病活动度更高，健康评估问卷、患者总体自我评估评分、压痛和肿胀关节计数、指炎、肌腱端炎、疼痛严重程度和对日常活动的干扰、疲劳严重程度和影响、纤维肌痛、焦虑和抑郁程度均高于“不太可能的神经性疼痛”患者（p < 0.05）。PainDetect 评分与疾病活动度、疲劳、抑郁、焦虑、广泛疼痛指数和症状严重程度量表的测量值相关（均 p < 0.05）。大多数（71%）有神经性样疼痛的患者符合美国风湿病学会 2010 年纤维肌痛标准。有“可能的神经性样疼痛”的患者介于“可能的神经性疼痛”和“不太可能的神经性疼痛”患者之间。
异常疼痛处理的神经性样疼痛作为证据在 PsA 患者中很常见。它与更高的疾病活动度和纤维肌痛有关。相当一部分患者有“可能的神经性样疼痛”，疾病和症状评分处于中间水平，这表明神经性样疼痛作为异常疼痛处理的证据是一个连续体，而不是并发的纤维肌痛。
神经性疼痛在银屑病关节炎中很常见。
银屑病关节炎患者的疼痛、疾病活动度、疲劳、抑郁、焦虑和合并症水平更高。
疼痛严重程度增加与疾病活动度、疲劳、抑郁和焦虑增加相关。
