A young woman presented with portal vein thrombosis and thrombocytopenia and developed further extensive thrombosis following treatment with heparin. Despite no previous heparin exposure, she was found to be strongly positive for anti-platelet factor 4 (PF4) antibodies. She had acute cytomegalovirus (CMV) infection and a monoclonal gammopathy. Commentary on: Nicolson et al. Anti-PF4 mediated thrombocytopenia and thrombosis associated with acute cytomegalovirus infection displays both HIT-like and VITT-like characteristics. Br J Haematol 2025; 206:1737-1742.
一名年轻女性出现门静脉血栓形成和血小板减少症,在接受肝素治疗后又发生了更广泛的血栓形成。尽管此前未曾接触过肝素,但发现她的抗血小板因子4(PF4)抗体呈强阳性。她患有急性巨细胞病毒(CMV)感染和单克隆丙种球蛋白病。评论:Nicolson等人。抗PF4介导的血小板减少症和血栓形成与急性巨细胞病毒感染相关,兼具肝素诱导的血小板减少症(HIT)样和疫苗诱导的免疫性血小板减少症(VITT)样特征。《英国血液学杂志》2025年;206:1737 - 1742。
