Although the diagnosis and management of chronic spontaneous urticaria (CSU) is well documented in the literature, some aspects of the disease remain unclear. We aimed to further describe the natural history, prognostic factors, humanistic burden and uptake of traditional and alternative therapies in patients with CSU. This was a prospective, cross-sectional analysis at a single centre. We reviewed patient medical records and conducted a survey in patients with CSU. 72 patients participated in the study with a median duration of CSU of 48 months. 30% of patients had symptoms that resolved in under 2 years with these patients trending towards an older age of onset of CSU (48 ± 17 years). 16% of patients had symptoms lasting 10 years or longer with these patients trending towards a younger age of onset (22 ± 16 years). Patients with a relapsing/remitting disease course (31%) and those with co-existing angioedema (57%) trended towards a longer median duration of CSU (96 and 50 months respectively) and were observed to have a higher proportion of patients reporting CSU duration of 10 years or longer (33% and 25%, p = 0.033 and p = 0.036 respectively). Patients with co-existing autoimmune/thyroid disease (19%) trended towards a shorter median duration of CSU (37 months). 54 patients (75%) reported sleep disturbance and 29 patients (43%) required emergency room visit(s) for symptomatic control. 84% of patients who trialed second generation antihistamines reported a response to treatment, while 73% of patients who trialed omalizumab reported a response to treatment. Patients using alternative medicine such as acupuncture, traditional Chinese medicine and naturopathic medicine had lower reported response rates (20–29%) to treatment. The natural history of CSU may be longer than previously reported with our study finding a median duration of symptoms of nearly 4 years with one-third of patients reporting a relapsing/remitting disease course. Younger age of onset, a relapsing/remitting disease course and angioedema may predict a longer duration of CSU, whereas older age of onset and co-existing autoimmune/thyroid disease may predict a shorter duration of CSU. Reported symptomatic benefit was higher from guidelines based pharmacologic therapy versus various alternative medicines.

自然史、预后因素和患者对慢性自发性荨麻疹治疗的感知反应。

虽然慢性自发性荨麻疹 (CSU) 的诊断和治疗在文献中有很好的记载,但该疾病的某些方面仍不清楚。我们旨在进一步描述 CSU 患者的自然病程、预后因素、人文负担以及对传统和替代疗法的吸收。这是在单个中心进行的前瞻性横断面分析。我们审查了患者的医疗记录,并对 CSU 患者进行了调查。72 名患者参加了该研究,CSU 的中位持续时间为 48 个月。30% 的患者症状在 2 年内消失,这些患者的 CSU 发病年龄趋向于更高年龄(48 ± 17 岁)。16% 的患者症状持续 10 年或更长时间,这些患者的发病年龄趋向于更年轻(22 ± 16 岁)。复发/缓解病程的患者 (31%) 和同时存在血管性水肿的患者 (57%) 趋向于更长的 CSU 中位持续时间(分别为 96 个月和 50 个月),并且观察到报告 CSU 的患者比例更高持续 10 年或更长时间(分别为 33% 和 25%,p = 0.033 和 p = 0.036)。共存自身免疫/甲状腺疾病的患者(19%)倾向于缩短 CSU 的中位持续时间(37 个月)。54 名患者 (75%) 报告了睡眠障碍,29 名患者 (43%) 需要急诊室就诊以控制症状。84% 试用第二代抗组胺药的患者报告对治疗有反应,而 73% 试用奥马珠单抗的患者报告对治疗有反应。使用针灸等替代疗法的患者,传统中药和自然疗法的治疗反应率较低(20-29%)。CSU 的自然病程可能比之前报道的要长,我们的研究发现症状的中位持续时间接近 4 年,三分之一的患者报告疾病复发/缓解。发病年龄越小、疾病复发/缓解和血管性水肿可能预测 CSU 的持续时间更长,而发病年龄越大和并存的自身免疫/甲状腺疾病可能预测 CSU 的持续时间越短。与各种替代药物相比,基于指南的药物治疗报告的症状益处更高。CSU 的自然病程可能比之前报道的要长,我们的研究发现症状的中位持续时间接近 4 年,三分之一的患者报告疾病复发/缓解。发病年龄越小、疾病复发/缓解和血管性水肿可能预测 CSU 的持续时间更长,而发病年龄越大和并存的自身免疫/甲状腺疾病可能预测 CSU 的持续时间越短。与各种替代药物相比,基于指南的药物治疗报告的症状益处更高。CSU 的自然病程可能比之前报道的要长,我们的研究发现症状的中位持续时间接近 4 年,三分之一的患者报告疾病复发/缓解。发病年龄越小、疾病复发/缓解和血管性水肿可能预测 CSU 的持续时间更长,而发病年龄越大和并存的自身免疫/甲状腺疾病可能预测 CSU 的持续时间越短。与各种替代药物相比,基于指南的药物治疗报告的症状益处更高。而发病年龄较大和同时存在自身免疫/甲状腺疾病可能预示着 CSU 的持续时间较短。与各种替代药物相比,基于指南的药物治疗报告的症状益处更高。而发病年龄较大和同时存在自身免疫/甲状腺疾病可能预示着 CSU 的持续时间较短。与各种替代药物相比,基于指南的药物治疗报告的症状益处更高。
