Acupuncture as a therapeutic intervention for post-COVID-19 vaccination urticaria: a systematic review and meta-analysis protocol

INTRODUCTION: The COVID-19 pandemic persisted for over 3 years since its onset in December 2019, posing an ongoing global threat to human health. In the absence of specific antiviral medications for COVID-19, vaccination has emerged as a popular preventive measure adopted by the general public. However, an undesirable consequence of COVID-19 vaccination has been the frequent incidence of urticaria, a type of adverse skin manifestations. Despite the prevalence of this issue, there is currently a lack of clinical evidence exploring the potential utility of acupuncture as a therapeutic approach to managing urticaria arising after COVID-19 vaccination. To address this knowledge gap, this study aims to comprehensively evaluate the effectiveness and safety of acupuncture as a therapeutic intervention for treating urticaria in the general population following COVID-19 vaccination. METHODS AND ANALYSIS: The retrieval strategies employed in this study involve obtaining all relevant articles published from December 2019 to October 2023. These articles will be obtained from databases including PubMed, EMBASE, Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (SinoMed), VIP database and the WanFang database. Subsequently, the collected articles will undergo a thorough screening process based on predefined inclusion and exclusion criteria. Additionally, study quality will be evaluated using the Cochrane risk bias assessment tool. To conduct the meta-analysis, we will employ the Review Manager software (RevMan V.5.3). Finally, the study findings will be evaluated for their level of evidence. ETHICS AND DISSEMINATION: As this is a secondary review of published clinical data, this study does not involve direct contact with human subjects, and therefore, ethical approval and consent are not required. The findings of the study will be disseminated through a peer-reviewed journal, ensuring that the results undergo rigorous evaluation by experts in the field.
