Abstract

Purpose: Increasing seafood consumption is associated with more frequent reports of food allergy. Little is known about seafood allergy (SFA) among adults in Vietnam. We investigated the characteristics of individuals with SFA and the risk factors for severe SFA.
Patients and methods: A cross-sectional, web-based survey was conducted among individuals aged ≥ 18 years from universities in Ho Chi Minh City (Vietnam) between December 2021 and July 2022. The survey was based on a structured, validated questionnaire related to FA. Strict definitions of “convincing allergy” were used. Multivariate analysis was used to estimate the risk factors for severe SFA after adjusting for covariates. Data were analyzed using JASP (v.0.16.3) and SPSS (v.22.0).
Results: Totally, 1038 out of 2137 (48.57%) individuals completed the questionnaire, of whom 285 (27.46%) had reported SFA. Convincing SFA accounted for 20.13% (209/1038) of the cases, with convincing shellfish allergy being more common than fish allergy. Participants with comorbid shellfish and fish allergy had higher prevalence of atopic dermatitis, peanut/nut allergy, other food allergy, and cutaneous and upper airway symptoms compared to participants with shellfish allergy (p < 0.05). The spectrum of reactive seafood was diverse and characterized by local species. The age of symptom onset was most commonly during late childhood and adolescence, with most reactions persisting into adulthood. A history of anaphylaxis, comorbid peanut, and tree nut allergy, and ≥ 3 allergens were associated with severe SFA.
Conclusion: Features of causative, coexisting seafood allergy, and risk factors for severe SFA were demonstrated, which can provide a reference for future studies.

Keywords: seafood allergy, shellfish allergy, fish allergy, Vietnam

越南某城市成年人对海鲜严重过敏的风险因素

目的：海鲜消费量的增加与更频繁地报告食物过敏有关。但人们对越南成年人的海鲜过敏症（SFA）知之甚少。我们调查了 SFA 患者的特征以及严重 SFA 的风险因素：2021 年 12 月至 2022 年 7 月期间，我们对胡志明市（越南）各所大学中年龄≥ 18 岁的人进行了横断面网络调查。调查以结构化的、经过验证的 FA 相关问卷为基础。采用了 "令人信服的过敏 "的严格定义。在调整协变量后，采用多变量分析估计严重 SFA 的风险因素。数据使用 JASP（v.0.16.3）和 SPSS（v.22.0）进行分析：2137人中有1038人（48.57%）完成了问卷调查，其中285人（27.46%）报告了SFA。有说服力的 SFA 占 20.13%（209/1038），有说服力的贝类过敏比鱼类过敏更常见。与贝类过敏的参与者相比，合并贝类和鱼类过敏的参与者患有特应性皮炎、花生/坚果过敏、其他食物过敏以及皮肤和上呼吸道症状的比例更高（p <0.05）。反应性海产品的种类多种多样，并以当地物种为特征。发病年龄多在儿童晚期和青少年时期，大多数反应会持续到成年。过敏性休克病史、合并花生和树坚果过敏以及过敏原≥3种与严重SFA有关：结论：研究显示了海鲜过敏的致病特征、共存特征以及严重SFA的危险因素，可为今后的研究提供参考。关键词：海鲜过敏；贝类过敏；鱼类过敏；越南
