2023年孕婦及新生兒弓形蟲感染症案例報告

2023年一名孕婦於懷孕28週時確診弓形蟲感染症，並於36週時產下男、女嬰各一名，其中女嬰因血清學檢驗弓形蟲特異性抗體IgM陰性、IgG陽性及IgG親和力試驗中度，並伴隨有左眼視網膜脈絡膜炎之症狀，判定為先天性弓形蟲感染症。孕婦於妊娠早期初次感染弓形蟲，可能會經由母子垂直傳染，造成新生兒嚴重的先天性弓形蟲感染症。受感染新生兒出現顱內或眼部病變，並使主要照顧者後續面臨醫療費用壓力及照護負擔。為預防新生兒先天性弓形蟲感染症，建議針對一般或有育齡婦女之家庭加強弓形蟲症之衛教宣導，有養貓的飼主宣導正確的飼養觀念，也建議具風險因子之備孕或懷孕婦女可諮詢醫師是否進行自費弓形蟲檢查。

In 2023, a case study of a pregnant woman was diagnosed with toxoplasmosis at 28 weeks of gestation. At 36 weeks, she delivered a boy and a girl. The female newborn tested negative for toxoplasmosis-specific IgM antibodies but positive for IgG antibodies with moderate avidity. She also had chorioretinitis in her left eye, leading to a diagnosis of congenital toxoplasmosis. Vertical transmission from mother to child can occur when a pregnant woman contracts toxoplasmosis in early pregnancy. This transmission can result in severe congenital toxoplasmosis in newborns. Infected infants may present with intracranial or ocular lesions, placing significant financial and caregiving burdens on their primary caregivers. To prevent congenital toxoplasmosis in newborns, it is crucial to prioritize health education regarding toxoplasmosis for households with women of childbearing age. Additionally, cat owners should receive education on proper cat care practices. We also recommend that women who are pregnant or plan to be pregnant consult a physician for evaluation of risk and the need for toxoplasmosis testing.
