摘要
背景：虾过敏（SA）是一个重要的公共卫生问题，但其总体患病率尚不清楚。方法：到2024年9月30日，系统检索PubMed、Web of Science和Embase，确定了40项研究，这些研究使用自我报告的症状、医生诊断、皮肤点刺试验、特异性IgE或食物刺激试验报告了SA的患病率。结果：自我报告症状性SA的总患病率估计为1.90%，自我报告医生诊断SA的总患病率估计为1.94%，而通过皮肤刺破或特异性IgE检测的总患病率估计为2.76%。值得注意的是，症状检测显示患病率较低，为0.43%，食物激发试验证实患病率为0.50%。研究中观察到相当大的异质性，患病率因地区和年龄组而异，未发现发表偏倚。结论：这些发现表明，SA的患病率因诊断标准、年龄和地区而异，强调需要统一的诊断标准来改进患病率估计并指导公共卫生策略。系统评价注册：标识符[CRD420251003956]。
Prevalence of shrimp allergy: a meta-analysis based on different diagnostic methods.
Background: Shrimp allergy (SA) represents a significant public health concern, yet its overall prevalence remains unclear.
Method: A systematic search of PubMed, Web of Science, and Embase through September 30, 2024 identified 40 studies that reported SA prevalence using self-reported symptoms, physician diagnosis, skin prick tests, specific IgE, or food challenge tests.
Results: The pooled prevalence was estimated at 1.90% for self-reported symptomatic SA and 1.94% for self-reported physician-diagnosed SA, while testing via skin prick or specific IgE yielded a prevalence of 2.76%. Notably, symptomatic testing showed a lower prevalence of 0.43%, and food challenge tests confirmed a prevalence of 0.50%. Considerable heterogeneity was observed across studies, with prevalence varying by region and age group, and no publication bias was detected.
Conclusion: These findings indicate that the prevalence of SA varies with diagnostic criteria, age, and region, underscoring the need for harmonized diagnostic standards to improve prevalence estimates and guide public health strategies.
