摘要

目的：英国的产前筛查和新生儿免疫规划防止垂直HBV传播。然而，目前尚不清楚HTLV-1是否正在传播。我们测定了2021年3月27日至2023年3月30日通过产前强化监测发现的乙型肝炎表面抗原阳性个体的HTLV血清阳性率。结果：在3583例个体中，8例HTLV-1阳性（2.2 / 1000,95% CI 1.0 / 1000 ~ 4.4 / 1000），无HTLV-2阳性（95% CI 0.0 ~ 1.0 / 1000）。黑人妇女HTLV-1血清患病率为5.3 / 1000（95%可信区间为2.1 / 1000至10.8 / 1000）。假设垂直传播率为20%，在5年的监测中，可能有4名（95% CI 1.0 - 10.0）婴儿可避免感染HTLV-1。由于可以通过教育HTLV-1阳性个体避免母乳喂养来预防传播，这意味着错过了避免新生儿感染的机会。结论：本可避免的HTLV-1垂直传播可能发生在这一人群中，呼吁加强公共卫生干预。

Infants of hepatitis B surface antigen-positive women of Black ethnicity in the UK may be at risk of acquiring human T-cell lymphotropic virus type 1

Objectives

The UK’s antenatal screening and neonatal immunisation programme prevents vertical HBV transmissions. However, it is unknown whether HTLV-1 transmissions are occurring. We determined HTLV seroprevalence among hepatitis B surface antigen-positive individuals identified through antenatal enhanced surveillance between 27/03/2021 to 30/03/2023.

Results

For 3583 individuals, eight were HTLV-1 positive (2.2 per 1000, 95% CI 1.0 per 1000 to 4.4 per 1000) and none were HTLV-2 positive (95% CI 0.0 to 1.0 per 1000). HTLV-1 seroprevalence in women of Black ethnicity was 5.3 per 1000 (95%CI 2.1 per 1000 to 10.8 per 1000). Assuming 20% vertical transmission rates, over five years of the surveillance, it is likely that four (95% CI 1.0 – 10.0) infants avoidably acquired HTLV-1. As transmission can be prevented through education of HTLV-1 positive individuals to avoid breastfeeding, this represents a missed opportunity for averting neonatal infection.

Conclusions

Avoidable HTLV-1 vertical transmissions are likely occurring in this population, calling for strengthened public health interventions.
