OBJECTIVES/HYPOTHESIS: Children have higher rates of asymptomatic SARS-CoV-2 infections or milder courses of infection, and their carrier status may potentially impact viral transmission to those providing them care. The aim of this study is to compare the existing COVID-19 preoperative screening protocols to the detection of SARS-CoV-2 viral particles in surgical samples.
Cross-sectional study.
We conducted a prospective study with consecutive convenience sampling of children undergoing adenoidectomy between January and April 2021. Total nucleic acid was extracted from adenoid tissue and real-time reverse transcription-polymerase chain reaction was conducted to test for the presence of SARS-CoV-2 viral particles. Univariate logistic regression was used to summarize the effect size of variables of interest on the odds of having SARS-CoV-2 positive adenoid tissue.
Forty adenoid samples were collected and 11 (27.5%) had a positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients with positive adenoids were older (11.8 vs. 7.9 years, odds ratio: 1.3, P = .01) and more likely to have had a positive nasopharyngeal swab in the previous 90 days (4/11 or 36% vs. 0).
These data are the first report on the presence of SARS-CoV-2 particles in pediatric adenoidectomy specimens, with a high percentage of patients showing evidence of viral particles within the adenoid. This finding calls in to question the utility of preoperative COVID screening protocols which have yet to be rigorously validated in asymptomatic patients and have the potential to delay patients' surgical care.

目的/假设:儿童无症状 SARS-CoV-2 感染或感染较轻的比例较高,其携带状态可能潜在影响为其提供护理者的病毒传播。本研究旨在比较现有的 COVID-19 术前筛查方案与手术样本中 SARS-CoV-2 病毒颗粒的检测。
横断面研究。
我们进行了一项前瞻性研究,对 2021 年 1 月至 4 月期间接受腺样体切除术的儿童进行连续便利抽样。从腺样体组织中提取总核酸,进行实时逆转录-聚合酶链反应,检测 SARS-CoV-2 病毒颗粒的存在。采用单变量逻辑回归总结感兴趣变量对 SARS-CoV-2 阳性腺样体组织的比值比效应大小。
共采集 40 个腺样体样本,11 个(27.5%)样本 SARS-CoV-2 逆转录-聚合酶链反应阳性。阳性腺样体患者年龄较大(11.8 岁比 7.9 岁,比值比:1.3,P=0.01),且在过去 90 天内更有可能鼻咽拭子检测阳性(4/11 或 36%比 0)。
这些数据是关于 SARS-CoV-2 颗粒在儿科腺样体切除标本中存在的首次报告,有很高比例的患者在腺样体中显示出病毒颗粒的证据。这一发现对术前 COVID 筛查方案的有效性提出了质疑,这些方案尚未在无症状患者中得到严格验证,且有可能延迟患者的手术治疗。
