Abstract: 
The causative role of maternal, anti-human leukocyte antigen (anti-HLA) class I antibodies in foetal and neonatal alloimmune thrombocytopenia (FNAIT) remains controversial. Furthermore, in FNAIT cases caused by anti-human platelet antigen-1a (anti-HPA-1a) antibodies, the possible additive effect of maternal anti-HLA class I antibodies on outcomes is unclear. Among 817 mother-father-neonate trios of suspected FNAIT, we assessed the possible association of maternal anti-HLA class I antibodies with neonatal platelet count, and the incidence of FNAIT caused by anti-HPA-1a antibodies. In 144 FNAIT cases caused by anti-HPA-1a antibodies, we investigated the possible association of maternal anti-HLA class I antibodies with neonatal platelet count, birth weight, and the incidence of intracranial haemorrhage (n = 16). Maternal anti-HLA class I antibodies were not associated with neonatal platelet count in suspected cases of FNAIT. There was no significant interaction between the presence of anti-HLA class I antibodies and anti-HPA-1a antibodies. In FNAIT cases caused by anti-HPA-1a antibodies, there was no association between the presence of anti-HLA class I antibodies and neonatal platelet count, birth weight, or occurrence of intracranial haemorrhage. This study's findings do not support the concept that maternal anti-HLA class I antibodies represent a risk factor of FNAIT or disease severity.
