Shortage of blood during the severe acute respiratory syndrome-COV-2 (SARs-COV-2) pandemic impacted transfusion practice. The primary aim of the study is to assess management of acute haemolytic crisis (AHC) in glucose-6-phosphate dehydrogenase(G6PD)- deficient children during SARs-COV-2 pandemic, and then to assess blood donation situation and the role of telemedicine in management.
Assessment of G6PD-deficient children attending the Emergency Department (ER) with AHC from 1 March 2020 for 5 months in comparison to same period in the previous 2 years, in three paediatric haematology centres. AHC cases presenting with infection were tested for SARs-COV-2 using RT-PCR. Children with Hb (50-65 g/L) and who were not transfused, were followed up using telemedicine with Hb re-checked in 24 h.
A 45% drop in ER visits due to G6PD deficiency-related AHC during SARs-COV-2 pandemic in comparison to the previous 2 years was observed. 10% of patients presented with fever and all tested negative for COVID-19 by RT-PCR. 33% of patients had Hb < 50 g/L and were all transfused. 50% had Hb between 50 and 65 g/L, half of them (n = 49) did not receive transfusion and only two patients (4%) required transfusion upon follow up. A restrictive transfusion strategy was adopted and one of the reasons was a 39% drop in blood donation in participating centres.
Fewer G6PD-deficient children with AHC visited the ER during SARs-COV-2 and most tolerated lower Hb levels. Telemedicine was an efficient tool to support their families. A restrictive transfusion strategy was clear in this study.
在严重急性呼吸综合征冠状病毒 2 型(SARS-CoV-2)大流行期间,血液短缺影响了输血实践。本研究的主要目的是评估葡萄糖-6-磷酸脱氢酶(G6PD)缺乏症儿童在 SARS-CoV-2 大流行期间急性溶血性危象(AHC)的管理情况,然后评估血液捐献情况和远程医疗在管理中的作用。
在 3 个儿科血液学中心,评估 2020 年 3 月 1 日至 5 个月期间因 AHC 就诊于急诊科的 G6PD 缺乏症患儿,与前 2 年同期进行比较。出现感染的 AHC 病例采用 RT-PCR 检测 SARS-CoV-2。Hb(50-65g/L)且未输血的患儿采用远程医疗进行随访,Hb 于 24 小时后复查。
与前 2 年相比,SARS-CoV-2 大流行期间因 G6PD 缺乏症相关 AHC 导致急诊科就诊人数下降了 45%。10%的患者有发热,所有患者的 RT-PCR 检测均为 COVID-19 阴性。33%的患者 Hb<50g/L,均进行了输血。50%的患者 Hb 在 50-65g/L 之间,其中一半(n=49)未输血,仅 2 名患者(4%)在随访时需要输血。采用了限制性输血策略,其中一个原因是参与中心的血液捐献量下降了 39%。
SARS-CoV-2 期间,因 AHC 就诊的 G6PD 缺乏症儿童人数减少,大多数患儿能耐受较低的 Hb 水平。远程医疗是支持其家庭的有效工具。本研究中采用了限制性输血策略。
